The terpenoid biosynthetic pathway and strategies for its manipulation have been reviewed recently (Mahmoud and Croteau blood pressure medication liver disease buy indapamide 2.5mg low price, 2002; Aharoni et al. A comprehensive listing of transgenic plants with altered terpenoid biosynthetic properties is available elsewhere (Aharoni et al. Ex amples include expression of heterologous synthases in tomato, leading to enhanced aroma in ripening fruit (Lewinsohn et al. Other endogenous, plant-derived terpenoids with demonstrated pharmaceutical properties include the anti-malarial agent artemisinin, the diuretic glycyr rhizin, and the cancer drugs Taxol and perilla alcohol. Several of these compounds are currently derived from endangered species in threatened ecosystems (Bouwmeester, 2006), while chemical synthesis of terpenes can be prohibitively costly and inefficient (Wu et al. Plants contain two terpene biosynthetic pathways; the mevalonate pathway leads to the synthesis of sesquiterpenes and triterpenes at the level of the endoplasmic reticulum, while the methyl-D-erythritol-4-phosphate pathway functions in the chloroplast to produce monoterpenes, diterpenes, and carotenoids (Aharoni et al. Most attempts to manipulate the pathways involve introducing terpene synthase genes whose products could divert pathway intermediates towards the production of desired, and in some cases novel, terpenes (Chappell, 2004). To date, generating monoterpenes in transgenic plants has proven easier than modifying the metabolism of longer-chain terpenoids (Aharoni et al. The com plexity of the biosynthetic pathway, giving rise to a vast number of natural products, and the subcellular compartmentalization of the processes pose challenges for terpenoid genetic engineering. Manipulating terpenoid bio synthetic pathways in plant species that produce the same class of terpenes is less problematic, because the plant already has the specialized structures necessary to carry out the storage and transport of volatile, hydrophobic compounds. In contrast, introducing novel pathways into species that lack the secretory structures required may prove to be far more difficult 94 Lois M. A recent comprehensive evaluation of the factors required for high-level terpene production in tobacco identified several effective strategies for enhancing synthesis as much as 1,000-fold (Wu et al. By over-producing, in the same subcellular compart ment, an enzyme producing an isoprenoid substrate and a terpene synthase that rapidly incorporates this substrate, Wu et al. Commercially important traits in trees have also been a focus of recent Agrobacterium mediated transformation (Tzfira et al. Tree improvement goals in clude increasing timber yield and decreasing generation time; together, these traits could pave the way for economically viable plantation forests, leading to decreased pressure on natural forests as sources of wood (Fenning and Gershenzon, 2002). In this regard, overexpression of a key enzyme in the gibberellin biosynthetic pathway resulted in enhanced bio mass and accelerated growth rate in hybrid aspen, but had a negative effect on rooting. Interestingly, the transgenic trees also exhibited longer and more numerous xylem fibers that could be advantageous in producing stronger paper (Eriksson et al. Altering plant composition could also enhance the production of bioethanol, a renewable energy source for the transportation sector with substantial positive environmental impact (Boudet et al. Finally, in poplar and aspen, biotechnology has proven to be an effective way to manipulate levels of the undesirable cell wall component lignin by downregulating the last step of the lignin bio synthetic pathway through an antisense strategy (Baucher et al. Since removal of lignin in the paper and pulp industry is an energy-consuming process that requires large amounts of hazardous chemicals, the success of the antisense trees holds promise for more environmentally friendly proc essing in the future. To date, most such clinically relevant proteins have been produced in tobacco, although potatoes, al falfa, soybean, rice and wheat have also been used successfully. While green tissue has a distinct advantage in terms of productivity, seeds or tu bers are most useful for delivery of an edible product such as a vaccine; they can be stored for long periods of time (Daniell et al. Edible vaccines may hold considerable promise for the developing world, where refrigeration, sterile syringes and needles, and trained health care personnel are frequently in short supply (Arntzen et al. Since many pathogens utilize mucosal surfaces as their point of entry, priming the entire mucosal immune system via oral stimulation is an especially at tractive mode of immunization (Streatfield et al. Nonetheless, lack of a profit incentive for private industry, coupled with concerns about in adequate biosafety infrastructure in developing countries and the complex ity of government-financed health care delivery systems, have resulted in the development of relatively few products (Ma et al. Oral immunization has been achieved using trans genic potatoes expressing antigens including the heat-labile enterotoxin from E. Despite these successes, it should be noted that there are no transgenic-plant-derived pharmaceuticals in commercial production (Ma et al. This group would be the first to carry out clinical trials of plant-derived candidate pharmaceuticals within the European Union regulatory framework. Plant-derived pharmaceuticals have many potential advantages over those produced in animal cell culture or by microbial fermentation. High yields, favorable economics, existing technologies for harvesting and processing large numbers of plants, and the possibility of expressing pro teins in specific subcellular compartments where they may be more stable, 96 Lois M. Banta and Maywa Montenegro all contribute to the choice of transgenic plants over bacterial expression systems for recombinant proteins (Daniell et al. Like animal cells, plants have the ability to carry out post-translational modifications, and can fold and assemble recombinant proteins using eukaryotic chaperones, but plant expression systems have the added benefit of minimizing the po tential for contamination with human pathogens (Woodard et al. Finally, multimeric protein complexes may be recon structed in transgenic plants by stacking transgenes through successive crosses among plants resulting from single transformation events (Hiatt et al. This is a particularly im portant consideration when producing multimeric secretory antibodies to protect against microbial infection at mucosal sites (Giddings et al. One concern about plant-based pharmaceuticals is the potential for non-mammalian glycosylation patterns that might result in immune sensi tization or loss of function (Bardor et al. However, at least one plant-derived monoclonal antibody was found to be functional despite differences in N-linked glycosylation (Ko et al. Other potential limitations of plant expression sys tems include low and/or variable yield (Chargelegue et al. Finally, contamination of food and feed crops with pharmaceutical crops, either in the field or post harvest, poses potentially serious health and public relations risks (Ma et al. By integrating an engineered marker gene, beta-glucuronidase, Barbara Hohn and coworkers have pioneered a strategy in which trans genic Arabidopsis has successfully been used to report enhanced rates of homologous recombination or point mutation due to heavy metal ions (Kovalchuk et al. Agrobacterium and Plant Biotechnology 97 Increasing levels of pollution resulting from global industrialization have focused attention on the possibility of phytoremediation: using plants to remove or inactivate pollutants from soil or surface waters. Factors that influence the utility of a plant in phytoremediation include (i) the availabil ity of the trace element in a form that can be taken up by the plants roots; (ii) the rate of uptake; (iii) the ability of the plant to transform the pollutant into a less toxic, and potentially volatile, compound; and (iv) the movement of the compound from the roots into the shoots (Kramer and Chardonnens, 2001). Theoretically, genetic manipulation of heavy metal accumulation in plants could be used to imbue a plant with any of these traits or to enhance an existing capability (Clemens et al. Introduction of bacterial genes has enabled the creation of transgenic Arabidopsis plants capable of converting the highly toxic contaminant methylmercury to the volatile and much less toxic elemental mercury (Bizily et al. Similar modifications have resulted in Arabidopsis and poplar able to process and sequester mercury ion (Rugh et al. To deplete arsenic contamination from groundwater, re searchers have introduced bacterial genes that confer on Arabidopsis the ability to extract and accumulate in the leaf levels of arsenic that would normally poison the plant (Dhankher et al. Second generation phytoremediating plants will likely capitalize on the finding that overex pression of a yeast vacuolar transporter in Arabidopsis leads to enhanced accumulation, and hence tolerance, of heavy metals such as cadmium and lead (Song et al. The advent of basic plant molecular biology, made possible in large part by the availability of Agro bacterium-mediated techniques for introducing and knocking out plant genes, has dramatically augmented our understanding of how plant archi tecture and generation time are regulated, and these discoveries may enable further improvements in yield. Banta and Maywa Montenegro brassinosteroid levels resulted in a more erect leaf structure in rice, in creasing yield under dense planting conditions (Sakamoto et al. Tissue-specific modulation of the growth hormone gibberellin catabolism in transgenic rice led to a semi-dwarf phenotype without a loss in grain productivity (Sakamoto et al. In other cases, yield may be en hanced by decreasing the time required for the plant to produce the edible portion. Dormancy in potatoes was controlled by expressing a bacterial gene that altered sprouting behavior (Farre et al. Other attempts to increase yield potential have centered on the photo synthetic process, and in particular the inefficiency of the carbon assimila tion pathway in C3 plants, a group that includes many agronomically important crop plants. Using Agrobacterium-mediated transformation, Matsuoka and co-workers have expressed three key C4 en zymes in rice (a C3 plant) (Ku et al. Another strategy, involving expression in tobacco of a cyanobacterial enzyme, successfully improved photosynthetic capacity and concomitantly increased the plants biomass (Miyagawa et al. However, grain production is tightly linked to ni trogen availability, and hence larger plants will not necessarily yield more grain unless soil nitrogen levels are sufficient (Sinclair et al. Among the approaches to mitigating these con straints are some that involve genetically modifying the crop plant. It is Agrobacterium and Plant Biotechnology 99 important to stress that there are also many highly successful non biotechnological practices that have been in use for centuries, including in tegrated pest and vector management, crop rotation, dissemination of pathogen-free plant material (Rudolph et al. Indeed, farming systems that combine careful land management with a diverse array of species and genetic backgrounds within a species can be highly productive even in the absence of modern varieties or biotechnology improvements (Brown, 1998). The lessons of such a holistic approach to agriculture are enjoying a resurgence of popularity among small and some medium-scale farmers in the industrialized world; for example, integrated production and organic farming guidelines are in practice on 85% of the farmland in Swit zerland (Xie et al. Nonetheless, the predominant model of agricul ture in much of the developed world is one of monocultures grown with high external inputs.

Exposures and outbreaks of communicable diseases in childcare settings and schools can result in spread to the general community. Section 1 includes the exclusion policies for children in childcare/preschool and schools. When the child enrolls in childcare or school, parents/guardians should be given a list of exclusion policies and given notice whenever these policies change. Some childcare facilities or schools may have this information in a student handbook or on their websites. Section 4 contains information on what diseases are reportable in Missouri, what information is needed when a report is made to the local or state health department, and a list of local and state health department disease prevention and control resources in Missouri. When a communicable disease of public health importance or an outbreak of illness in a childcare setting or school is reported to the local or state health department, the health department will investigate the situation. Specific prevention and control measures will be recommended to reduce spread to others. These measures require the cooperation of the parents/guardians, child caregivers, children, school health staff, healthcare providers, childcare health consultants, and environmental health inspectors. In these situations, recommendations will be made by the health department regarding: Notification to parents/guardians, childcare providers, school health staff, and healthcare providers of the problem. Childcare providers and school health staff should be aware that these situations can be very stressful for everyone concerned. Reports to local or state health department Childcare providers or school health staff should notify the local or state health department as soon as an outbreak is suspected. Doing so can reduce the length of the outbreak and the amount of activity required to bring it under control. This manual contains fact sheets on most communicable diseases that you would expect to see in childcare or school settings. Sample line list A line list is a tool that can be used by the provider when the childcare or school is receiving sporadic reports of illness in children from different classrooms. It is a standardized way to analyze data to determine the presence of an outbreak. In a line listing, each column represents an important variable, such as name, age, and symptoms present, while each row represents a different case. Contact information for your local public health agency can be obtained from the following website: health. The phrase Reportable to local or state health department appears under the title of the disease. If children or staff have been diagnosed with or are suspected of having any of these diseases, contact the local or state health department for consultation before sharing any information about the disease. Bed bugs may be difficult to control without help from a pest control professional. Bed bugs are small (up to 1/4" long) flattened, wingless insects that feed on the blood of people and certain animals. Bed bugs move quickly, feed at night, and hide in small spaces (under bed mattresses, in furniture, etc. Bed bugs feed at night, so you may not be aware that you were bitten, or the bites can be mistaken for bites from another pest (fleas or mosquitoes). They quickly crawl to find a human host, feed for less than 5 minutes, and then hide. Bed bugs like to hide in small places; therefore, it is possible that bed bugs will crawl into luggage, beds, or furniture that is being moved from one place to the next. It is also possible for bed bugs to crawl through small spaces between units in a hotel or apartment building. Because bed bugs can survive for many months without feeding, they may already be present and hidden in apartments or homes that appear to not have any bed bugs. Bed bugs are spread between residences when they hide and are transported in luggage, furniture, or other items. Because several different kinds of insects look like bed bugs, carefully compare the bugs with good reference images to confirm their identity. If still unsure about the identity of bugs in the home, contact a pest control expert. Cast skins, which are empty shells of bed bugs as they grow from one stage to the next, may be present. In heavier infestations, live bed bugs may be found further away from the bed (window and door frames, electrical boxes, cracks in floors and ceilings, within furniture, behind picture frames on the wall). Taking free furniture items left by the curb for disposal or behind places of business is not recommended. The insecticides available are commercial products requiring special equipment and training and are not readily available in over-the-counter products. Work with a certified pest control operator to determine how insecticides will be used and applied in your residence. Insecticide treatments may require you to leave your home for a few hours or even several days. For more information about bedbugs, refer to University of Missouris Extension Office website at: extension. Bronchitis and bronchiolitis tend to occur more often in the fall and winter months. When infants and young children experience common respiratory viruses and are exposed to secondhand tobacco smoke, they are at risk of developing bronchiolitis, bronchitis, pneumonia, and middle ear infections. Most of these organisms can cause other illnesses and not all persons exposed to the same organism will develop bronchitis or bronchiolitis. If you think your child Symptoms has Bronchitis: Your child may have a runny nose and fever. Also if your child has a sore medicines to anyone throat or cough that wont go away. Antibiotics do not work for illnesses caused by a virus, including some types of bronchitis. Persons with Campylobacter infections may have mild symptoms or may not have any symptoms at all. Spread can also occur through handling infected pets, usually puppies, kittens, or farm animals. People most often get Campylobacter by eating contaminated food, or drinking contaminated water or unpasteurized milk. Children who have Campylobacter in their feces but who do not have symptoms do not need to be excluded. In more severe cases, antibiotics can be used, and may shorten the duration of symptoms if given early in the illness. In the classroom, children should not serve themselves food items that are not individually wrapped. If you think your child has Symptoms Campylobacteriosis: Your child may have diarrhea, vomiting, or a fever. Childcare: Spread Yes, until diarrhea has By eating or drinking contaminated beverages or food, stopped. The illness can spread as long as Campylobacter In addition, anyone with bacteria are in the feces. Always disinfect food preparation surfaces, especially after handling or cutting raw chicken. Within several hours, the bumps turn into small blisters (fluid-filled bumps), and then scabs after a few days. Chickenpox can be severe in newborns, adults, and those with weakened immune systems. Complications that commonly lead to hospitalization and can lead to death include severe skin and soft tissue infections, pneumonia, encephalitis, and dehydration.

This functionality offsets the Pneumatic jet nebulizers (most commonly used in the issues of portability, weight, noise, cost, and time of admin hospital or clinic) are low-cost, mass-produced, single istration associated with nebulizers. Nebulizer systems may deliver a dose of aerosolized medication is an important include a nebulizer, compressor or power pack, tubing, determinant of patient adherence, especially in the outpa and accessories. Jet nebulizers require 2 to 10 liters per minute of pressurized gas generated as a jet through a small open ing, generating a region of Figure 5. Labeled schematic illustration of the operation of a standard jet nebulizer sub-ambient pressure above a small capillary tube placed in the medication cup or reservoir. The solution to be aero solized is pulled into the gas stream and then sheared into a liquid flm. This flm is unstable and rapidly breaks into droplets due to surface tension forces. As larger droplets impact the baffe placed in the aerosol stream, smaller par ticles form and become entrained in the gas stream inhaled by the patient. Depicted in Figure 4 (see page 17) are four different designs of the pneumatic jet nebulizer: jet nebulizer with reservoir tube, jet nebulizer with collection bag, breath-en hanced jet nebulizer, and breath-actuated jet nebulizer. Schematic diagram of a breath nebulizer with the reservoir tube is the least expensive enhanced nebulizer and most routinely used of the four designs. This nebulizer provides continuous aerosol during inhalation, exhalation, proximal to an equally small capillary tube. As the pressur and during breath-holding, causing the release of aerosol to ized gas leaves the jet, it mixes with the liquid medication ambient air during exhalation and anytime when the patient in the capillary tube to create a mist. The patient inhales aerosol gated tubing attached to the expiratory side of the nebu from the reservoir through a one-way inspiratory valve and lizer helps to decrease drug loss and increase inhaled drug exhales to the atmosphere through an exhalation port mass.

Breath-actuated Jet Nebulizer: Breath-actuated nebuliz unable to aerosolize viscous solutions and can degrade ers are designed to increase aerosol drug delivery to patients heat-sensitive materials. Consequently, should not be used to nebulize suspensions, such as loss of medication during expiration is greatly reduced, as budesonide, or proteins. Small-volume ultrasonic nebulizers are commercially avail able for delivery of inhaled bronchodilators. Large volume Electronic Nebulizers ultrasonic nebulizers are used for sputum induction. Vibrating Mesh Nebulizers these other models are called electronic nebulizers and can be classifed as either ultrasonic or vibrating mesh. Electronic nebulizers are small, ity to generate aerosols with a fne-particle fraction, which quiet, and typically powered by standard size batteries. In some instances, because of the higher Ultrasonic Nebulizers effciency of these nebulizers, it may be necessary to adjust medication dosage to prevent a possible adverse effect Ultrasonic nebulizers incorporate a piezoelectric crystal because of overdose.

For example pulse pressure of 100 purchase 1.5mg indapamide mastercard, in the World Trade Center attacks on September 11, 2001, 658 employees of the investment rm of Cantor Fitzgerald died, leading to the collapse of Cantor Fitzgeralds core interdealer business in the United States (Cantor Fitzgerald, undated). Economic and Intangible Consequences of Property Damage Terrorist attacks can destroy both physical and intellectual property. Attacks that damage facilities, ships, vehicles, airplanes, infrastructure, or products and raw materials reduce the assets of private rms. In cases in which power is disrupted or computer networks are targeted, loss of data may also reduce rm assets that enable future revenues. Damage to infrastructure, facilities, and information systems may propagate into both short and long-term economic disruptions. Firms may immediately experience delivery delays, loss of revenue from interrupted business, and increased transportation costs. Reduction of demand or supply could eliminate the benets of economies of scale until facilities and infrastructure can be replaced. As the magnitude and duration of disruptions to infrastructure, facilities, and informa tion systems increase, the consequences can be more permanent. In extreme cases, disruptions can lead to long-term or permanent loss of business. Following a large re in a Philips Electronics manufac turing facility, Ericssons inability to adapt its supply chain quickly for mobile phone components contributed to the rms loss of signicant market share to competitor Nokia (She, 2005). Business disruptions can lead to signicant loss of revenue for local and state governments. The pooled eects of destruction of private infrastructure along with public infrastructure can lead to signicant loss of public services, such as freight and public transportation. Tese public-sector eects were most recently demonstrated by the devasta tion wrought by Hurricane Katrina. Loss of population and business prompted initial projections of a budget shortfall of as much as $1 bil lion for the state government of Louisiana2 and freight transportation was disrupted for months by damage to rail, road ($3 billion [Burton and Hicks, 2005]), and port facilities ($1. Economic and Intangible Consequences of Responding to Terrorism The unfolding of events and reactions following a terrorist attack can result in a cascade of secondary consequences. In addition to the direct costs of emergency response to the attack, subsequent changes in the nations posture toward terrorism and the economic impact of those changes can also be construed as consequences of terrorism. Experience from the events of September 11, 2001, strongly suggest that terrorist events will be followed by increased public and private-sector secu rity investments or increases in insurance rates as rms and the public sector react to new perceived and realized threats (Zycher, 2003). Terrorism-induced changes in risk perception may also lead indi viduals and rms to change their consumption and investment pref erences. This could be particularly signicant for luxury and substitutable industries, such as jewelry or travel tourism, respectively. Large terrorist events might also provoke shifts in foreign policy and have domestic political consequences. By analogy to the costs of the Iraq war, Linda Bilmes and Joseph Stiglitz (2006) have suggested that costs from shifting political focus might compound other human and economic consequences of the Iraq war, thereby contributing to 2 Hochberg (2005). Note that apparent increases in sales tax receipts from increased pur chases ultimately eased the projected decits. Consequences of Maritime Terrorism 37 reduced condence in the national economy, and ultimately leading to the macroeconomic eect of decreased foreign investment. This kind of eect could alter even technological innovation, if severe uncertainty about the future were to lead to a reduced tolerance for risk invest ments. Tese kinds of eects could lead to shifts and loss of value in domestic securities markets. Tough these consequences are poorly understood and dicult to estimate, it is prudent to consider proactively how they may arise and how alternative responses might amplify or counter them. Scenario based tools, such as day-after gaming, may be particularly useful for assessing risk management for these types of consequences. Methods of Estimating Consequences of Maritime Terrorism Past maritime terrorist events provide the most direct means of esti mating the consequences of future attacks. However, there are two sig nicant limitations to relying on this type of historical analysis. As dis cussed in Chapter Two, a few events can be used as benchmarks for the potential consequences of terrorist attacks. However, the small number of events is limiting because it does not provide a representative sample of attack modes that terrorism analysts have discussed. Second, his torical analysis does not provide a means for extrapolating to events that may occur as terrorists adapt and aect maritime systems in new ways. Terefore, additional approaches are necessary to augment this direct historical analysis. In the analysis of risks of cruise, passenger, and container ships in the subsequent chapters, we used three addi tional sources of information. First, terrorist attacks in nonmaritime arenas can provide a mea sure of typical fatalities and injuries from dierent attack modes. While maritime attacks are relatively rare, terrorists have been active with land-based and aviation-based attacks for decades. Reviewing shoot ings, suicide bombings in crowds, and hijackings in other scenarios 38 Maritime Terrorism: Risk and Liability can provide a better understanding of what the consequences of these attacks might be in the maritime domain. Second, modeling and simulation can provide estimates of direct and indirect impacts of terrorism. Physical models have been used to understand the impacts of weapons on structures and humans. Tese can be used to estimate the casualties from conventional, nuclear, radiological, and biological weapons. Direct economic eects can often be easily estimated through modeling and simulation, though uncertainty in the extent of disruptions must be addressed. Economic models, such as input-output models, represent the interdependen cies of sectors in the economy. Day-after games and scenario analysis can be used to elicit expert estimates of consequences and how rms and individuals will respond to terrorist events. All of these tools can be used to estimate the indirect eects of terrorism on regional and national economies. Labor disputes like the 2002 West Coast port lockout provide another source of case studies that can be used as a proxy for disruptions. We discuss the tort liability implications of this distinction in Chapter Four of this book. The victims of terrorist aggression are fre quently private citizens and commercial interests, for whom the central problem in the wake of a terrorist attack is recovering from the damages inicted and, where possible, seeking compensation for those damages from any available resource. Terrorism, however, presents problems for this sort of conventional tort recovery. Lawsuits led by victims against terrorist perpetrators can be dicult to pursue, particularly when per petrators deliberately kill themselves to perpetrate an attack, or when perpetrators are international fugitives who are impossible to locate or to investigate. One such challenge lies in developing the evidence to tie responsibility for terrorist acts to foreign governments. A second involves overcoming traditional legal rules that, until recently, protected sovereign states from civil suits brought by U. Civil liability is an important dimension to consider in examining the impact of maritime terrorist threats on the United States. Liability is tied not only to the harms actually inicted by an attack, but also to complicated legal rules that shift associated costs from one party to another. In the wake of an actual terrorist event, the costs of civil liability to such parties could become enormous. Yet quantifying the magnitude of liability risk in connection with terrorist attacks remains dicult, because tort principles associated with such attacks are not fully settled under U. First, mari time commerce often involves intricate relationships between multiple business entities that may share responsibility for shipping operations and that owe contractual obligations to each other. For this reason, liability principles and incentives relating to accidents provide little insight with regard to terrorism. Finally, liability problems in mar itime terrorism are complex partly because potential attack scenarios are broadly varied and fundamentally heterogeneous, in ways that may be tied to basic legal questions about U. Related scenarios range from small-scale attacks on domestic pas senger shipping4 to catastrophic attacks involving concealed weapons of mass destruction entering the United States through seaports.

1.5 mg indapamide mastercard

This is because bacterial death on a copper surface is probably caused by a different mechanism pulse pressure waveform indapamide 2.5 mg on line, such as damage to the cell or organisms outer membrane. Copper is not genotoxic (does not affect the integrity of an organisms genetic material, Cross et al. Copper can be cytotoxic at very high concentrations, as, for example, when encountered by a microorganism on a dry copper surface. This means that, on a copper surface, the bacterium dies without any change in its genetic material. Despite the fact that copper has been around for 10,000 years, bacteria still cannot survive on its metallic surfaces. In contrast, resistance to beta-lactam (penicillin-type) antibiotics became prevalent after only 30 years of use. While existing evidence indicates that microbes will not be resistant to copper as an antimicrobial material, experimental and empirical studies need to be conducted so it can be further confirmed. Environmental Protection Agency approved the first set of registrations of copper alloys as antimicrobial materials with public health claims. Before the antimicrobial copper alloy registration was granted, only antimicrobial gases liquids, sprays and concentrated powders were registered to make antimicrobial public health claims. Significantly, to obtain a non-public health registration, registrants need only demonstrate that the substance will not cause unreasonable adverse effects to human health or the environment; they do not have to demonstrate the antimicrobial efficacy of the substance. An example of a treated article is the addition of a fungicide to paints for the purpose of preventing the development of mildew. In this application, the fungicide protects the paint, but it does not protect people who touch the painted surface from microbes. For this reason, manufacturers of fungicide paints are not legally permitted to make public health claims. Accordingly, this type of restriction forbidding manufacturers to make public health claims applies to all products granted Treated Article Exemptions. Articles or products that claim to be effective in controlling infectious microorganisms, such as E. These articles or products can then make a public health claim that goes beyond the preservation of the treated article itself. Regulations require the successful completion of a lengthy registration process before products can be labeled antibacterialand their public health benefits promoted. The results, summarized in this chapter, were a resounding success that culminated in the registration of 275 antimicrobial copper alloys with public health claims. The length of time pathogens were exposed to copper surfaces increased from five minutes to two hours. The exposure times between the pathogens and copper surfaces increased from five minutes to two hours, and coatedantimicrobial surfaces were replaced with solid copper alloy surfaces. For this protocol, a 99% or greater efficacy was required to justify antimicrobial claims. By doing so, a meaningful and level playing field will be maintained as efficacy determinations are made on other solid materials. These studies are undertaken to generate data by which the hazards and risks to users, consumers and third parties, including the environment, can be assessed for pharmaceuticals, agrochemicals, cosmetics, food and feed additives and contaminants, novel foods and biocides. In the remaining six tests (all under the most rigorous Continuous Reductiontest protocol), the bacteria count was reduced by 99. Results for Efficacy of Copper Alloy Surfaces as a Sanitizer: In this test protocol, a reduction in live bacteria greater than 99. These efficacies are typical against all five microorganisms by all five copper alloys. Source: Michels and Anderson (2008) Initial Concetration Viability on S304 Viability on C110 1. The results for Staphylococcus aureus and Enterobacter aerogenes, which are representative of typical data, are illustrated in Figure 16. These results confirm that the antimicrobial efficacy of copper alloys is robust and durable. Copper alloy C26000 performed just as well in the initial two hour antimicrobial efficacy test as it did after the six wet and dry wear cycles. Source: Michels and Anderson (2008) Results for Continuous Reduction of Bacterial Contamination on Copper Alloy Surfaces In this test protocol, a reduction of >99. Similar results were achieved with all microbes on all five of the copper alloy surfaces. Clearly, these results prove that the antimicrobial efficacy of copper alloys is consistent, strong, enduring and reproducible. Seven additional alloys have since been registered and many more will eventually be added. The alloys are registered as six separate groups according to their respective copper content. Laboratory testing has shown that when cleaned regularly: Antimicrobial Copper Alloys continuously reduce bacterial* contamination, achieving 99. In particular, it is important for users to understand that the registered copper alloys are a supplement to and not a substitute for standard infection control practices, and that all current infection control practices, including those related to cleaning and disinfection of environmental surfaces, must continue to be followed. Antimicrobial copper alloys are intended to provide supplemental antimicrobial action in between routine cleaning of environmental or touch surfaces in healthcare settings, as well as in public buildings and the home. Users must also understand that in order for antimicrobial copper alloys to remain effective, they cannot be coated in any way. The Copper Alloy surface material has been shown to reduce microbial contamination, but it does not necessarily prevent cross-contamination. As has been noted throughout this document, any promotional materials developed for the U. Included in the label are directions for use and approved uses for Antimicrobial Copper Alloy products. More than 100 different potential product applications were cited in the registrations for their potential public health benefits. Manufacturers that incorporate registered copper alloys into their products can now make public health claims for those products. To attain this registration, five copper alloys representing the major alloy families were subjected to three rigorous tests to evaluate their antimicrobial efficacy. The five organisms tested were: Staphylococcus aureus, Methicillin-resistant Staphylococcus aureus, Pseudomonas aeruginosa, Enterobacter aerogenes, and Escherichia coli O157:H7. All testing was conducted in 95 accordance with the Organisation for Economic Co-operation and Developments Good Laboratory Practice guidelines. The alloys were divided into five groups according to their nominal copper content. Manufacturers have to promote the proper use and care of these products and must specifically emphasize that the use of these products is a supplement and not a substitute for routine hygienic practices. Department of Defense Funding for Antimicrobial Copper Research and Other Hospital Trials DoD Addresses Problem of Keeping Injured Soldiers Safe from Hospital-acquired Infectionsthe U. Department of Defense (DoD) has vested interests in the potential for antimicrobial copper surfaces to reduce hospital-acquired infections: thousands of enlisted servicemen and servicewomen in the U. The situation among armed forces casualties is no different from that of patients in the public sector, but DoD wants its injured soldiers returned home without risks from infections. The military however, thought these infections were caused by obscure organisms found in desert soil. Hospital-acquired Acinetobacter baumannii infected more than 700 soldiers in Iraq from 2003 until the beginning of 2007 (Wired, 2007). More than 70 patients at Walter Reed Hospital eventually contracted Acinetobacter blood infections. Other infected patients and pathogen carriers surfaced at Landstuhl, Germany; Bethesda, Maryland; and Balad Airbase, an embarkation point for troops leaving Iraq. By early 2005, nearly one-third of wounded soldiers admitted to the National Naval Medical Center had been infected by the bacteria (Wired, 2007). Until a few years ago, most strains of Acinetobacter baumannii could be treated with a wide variety of drugs. Strains of Acinetobacter are now emerging that are resistant to most many types of traditional treatments.

Insomnia is a set of symptoms with a large number sleep without those same conditions being present. Bedtime and wake-up time should be about the same time on school nights and non-school nights. Avoid high-energy activities, such as rough play, and stimulating activities, such as watching television or playing computer games, just before bed. Make sure your child spends time outside every day whenever possible and is involved in regular exercise. A low-level night light is acceptable for children who fnd completely dark rooms frightening. Children can easily develop the bad habit of needing the television to fall asleep. Its also much more diffcult to control your childs viewing if the set is in the bedroom.

On the other hand arrhythmia and chest pain order indapamide toronto, Rhizobium nomenclature encompassing Agrobacterium is increasingly accepted for reporting ecological and taxonomic studies, and for cataloguing culture collections. Since the Approved Lists were published, all other genera containing plant pathogenic species have been the subject of substantial revision. As indicated, there is little or no taxonomic data to support Agrobacterium as a genus separate from Rhizobium. Perhaps it arises from a misun derstanding of the nature of names in taxonomy, from over-emphasis given to the particular implied characters of the two genera, and from a habit of thought. Taken literally, the etymology of the name Rhizobium implies an association of the bacterium with plant roots; however subsequent use has resulted in the name being applied to nitrogen-fixing symbionts of legumes. The etymology of the name Agro bacterium implies an association of the bacterium with soil, but subse quent use has resulted in the named being applied to oncogenic pathogens. To apply the epithets tumefaciens to strains inducing crown-gall and the epithet rhizogenes to strains that induce hairy root, and to refer all onco genic stains to Agrobacterium would make common-sense if it were not for the fact that binomial nomenclature has the intention of indicating a hi erarchy of natural relationships (Sneath, 1988; Goodfellow and ODonnell, 1993). Descriptive terms necessarily refer to one or a few characters, often regulated by a few genes that may not be present in all members of a taxon, especially after revision in classification (Young, 2000b; Young et al. As taxa are redefined to include or exclude populations that do not conform to all the characters of the original description, so names lose their descriptive relevance (Young, 2001; Sneath, 2005). The etymol ogy of generic names Agrobacterium and Rhizobium is not indicative of their current use, nor can the epithets tumefaciens and rhizogenes be ap plied descriptively to species. In cases where genera have been divided, or species distributed into genera unfamiliar to a scholar, the application of novel binomials has created little tension, as when comprehensive revisions of Pseudomonas has resulted in transfer of species to genera distributed across the Proteobacteria (Kersters et al. However, in this particular case, two genera with popular and long-standing names, Agrobacterium and Rhizo bium, have been amalgamated. This poses a burden on translation from the old to the new nomenclature for those who have a developed familiarity with Agrobacterium nomenclature, but it is not insuperable, and is unlikely to pose difficulties for those who approach bacterial nomenclature for the 206 John M. The reward is a nomenclature that allocates due weight to taxo nomic and pathogenic differences. Following publication of nomenclature based on phenotypic species (Holmes and Roberts, 1981) and support for this concept (Bradbury, 1986; Moore et al. Application of names, whether as references to pathogenic (Kersters and De Ley, 1984) or natural (Holmes and Roberts, 1981; Bradbury, 1986; Young et al. The taxonomic literature contains nomenclature based on distinct pathogenic characters (Jarvis et al. Amal gamation with the genus Rhizobium does not affect the validity of the ear lier nomenclature and the relevant nomenclature can still be used, although the special purpose nature of the nomenclature should not be lost sight of. A possible complication would only arise if in future a novel oncogenic pathogen was proposed as an Agrobacterium sp. In such a case, as well as a circumscription of the novel species, it might be required of proposers of novel Agrobacterium species that they produce a circumscription to justify Agrobacterium as a genus distinct from Rhizobium. The term agrobacteria can be used with little ambiguity to refer spe cifically to bacteria with oncogenic capability based on the expression of Ti or Ri plasmids irrespective of taxon, in a way analogous to the applica tion of rhizobia. The Subcommittee on the Taxonomy of Agrobacterium and Rhizobium of the International Committee on Systematics of Pro karyotes suggest that. The term agrobacteria will need to be carefully applied in future if more widespread examples are discovered of Agrobacterium species with legume nodulating, nitrogen-fixing capabilities, or of Rhizobium species with oncogenic capabilities, or of Agrobacterium species from other environ ments (Popoff et al. Conn (1938) proposed the bacterial family, Rhizobiaceae, which originally included Rhizobium, Chromobacterium and Alcaligenes. Subsequently it included Agrobacterium and Rhizobium (Jordan and Allen, 1974), and Agrobacte rium, Rhizobium and Bradyrhizobium. Most recently, genera included in the family Rhizobiaceae are Rhizo bium, Agrobacterium, Allorhizobium, Carbophilus, Chelatobacter, and Ensifer. The relationships of these genera are likely to be modified by more detailed studies based on a wider selec tion of sequence data that include more representatives of related taxa. As noted, caution is in order when classification is based solely on a single sequence comparison because analyses give differing results de pending on the chosen algorithm and, most particularly, on the selection of included sequences as shown by comparison of inferred phylogenies. Strains representing Bartonella, Brucella, Blastobacter, Phyllobacterium and Mesorhizobium have been reported as interspersed between the mem bers of the Rhizobiaceae (Young and Huakka, 1996; De Lajudie et al. However, as now understood, the distribution, diver sity and systematics of these pathogenic bacteria is similar to those of other bacteria. They are small but significant populations of the soil micro flora that comprise closely related bacteria with the capacity to exchange characteristic plasmids that usually confer oncogenic capabilities affecting plants, but can also form symbiotic nitrogen-fixing associations with leg ume plants. The oncogenic spe cies are members of the genus Rhizobium, whose species, until now, have largely been characterized on the basis of their symbiotic nitrogen-fixing associations with legume plants. However, the present record of character ized species is strongly biased in favour of organisms of anthropocentric interest and there is little basis for believing even that nitrogen-fixing or oncogenic strains are the predominant representatives of species with which they are associated; these nitrogen-fixing strains almost certainly represent only a small part of the greater diversity of soil bacteria poten tially identifiable with this genus. The past literature that has separated these similar bacteria into distinct taxa has been an obvious hindrance to conceptualizing their ecology. If formal nomenclature is to serve the pur pose of indicating natural bacterial relationships then oncogenic strains must be identified in Rhizobium. It can be expected that novel species of Rhizobium will be identified that are uncharacteristic of the genus as now understood, and in these circumstances, names established and maintained as keys to characters such as tumorigenic capabilities or nitrogen fixation can be expected only to become more confusing.

Cheap indapamide 2.5mg line

Because of its thermotolerance blood pressure chart diastolic indapamide 1.5mg online, it has been isolated from decaying plant materials, compost, wood chips, hay and crops, as well as a variety of organic substrates, including stored grains and stored sweet potatoes. Although it does not normally grow indoors, it has occasionally been found to amplify indoors where ideal growth conditions. It has been isolated from a number of substrates, including house dust, soil, plant litter, dried nuts and seeds, textile materials, and water-damaged products. They have been reported from soils, plant parts, paper pulps, photographic optics, and other substrates. These two species of Aspergillus are morphologically and ecologically very similar. These fungi usually grow on indoor materials subjected to high humidity or in indoor environments with prolonged high 1 Xerophilic (dry loving) fungi are fungi that require low water content (or low water activity) in a substrate for spore germination and for growth. Carpets on concrete slabs are also susceptible to xerophilic species of Aspergillus and Eurotium. Another source of these fungi is preserved food products, such as fruit jams and food of high sugar content. Aureobasidium pullulans: It is a phylloplane2 fungus and likes to grow on wet surfaces, such as shower walls and house sidings. Species of the genus are well known as wood decay fungi and destroyers of paper products. Many of them are agricultur ally and economically important because they infect corn, rice, sorghum, and other grass crops. They produce large spores (9 to 32 mm wide and 16 to over 300 mm long) of non-respirable size. In addition, species of the genus are known producers of trichothecene mycotoxins. Memnoniella echinata: this is a species closely related to the genus Stachybotrys. In fact, the species may be found growing with Stachybotrys chartarum on water-damaged paper products. Some species are ex tremely common in the environment, but a few species have very unique ecological niches. This genus includes species that can grow in xerophilic to hydrophilic conditions. It has also been isolated on paper and is common on dead leaves and stems of more than 50 different plants. The spores are particularly abundant in the fall, which suggests the source of the fungus is outdoors. Paecilomyces variotii: this species is commonly associated with water-damaged wood products (such as wood subfloor) and with dust. Stachybotrys chartarum: this species is one of approximately 20 species in the genus Stachybotrys. The fungus produces dark, slimy, ellipsoidal to broadly ellipsoidal spores measuring 6-12 x 4-10 mm. The spores may be dispersed by insects, small animals, water, or through air when disturbed. As a saprophyte, the fungus is easily isolated and cultured on the common fungal media. However, for the correct identification of the fungus, cornmeal agar and 2-percent malt extract agar are recommended. The isolation and detection of Trichoderma in indoor environments may be from house plants, outdoors, or water damage. They have been found in various substrates including soils, roots, straw, wood, wood pulp, timber, paper, textiles, jet fuel, and rotting wood. They often produce green spore masses on wet wood out doors and in basements and crawl spaces. They have been observed on water-damaged, wet furniture made of wood and particleboard. This fungus may produce a strong musty, moldy (or coconut-like) odor when growing in a closed space, such as a basement. The fungus is found chiefly on substrates with high sugar or salt content (low water activity), but has been isolated from soils, samples of paper, and food stuffs including jam, bread, cakes, salted fish, milk, and fats. Sampling in snow-covered conditions in northern states or on rainy days may affect outdoor airborne mold spores. Professionals need to take this into consideration when planning for sampling and when interpreting the results. It may be instructional to compare results from the indoor area being investigated with other indoor non-problem areas. All samples taken for molds require analysis in a laboratory to minimize contamination. Indirect measurements of airborne mold spores by direct read-out instruments have been attempted. Particle counters may detect airborne particles, including mold spores, but there is no ratio that can be used to calculate concentrations of airborne mold spores. A direct read-out meter measuring mold-specific enzymatic activity has been introduced in the last few years, but the reading is qualitative and there is little field data to support its application. Field Guide for the Determination of Biological Contaminants in Environmental Samples. There are many hundreds of mycotox ins with different biological properties (Etzel 2002, Norred and Riley 2001). The different chemical groups of mycotoxins include aflatoxins, fumonisins, ochratoxins, rubratoxins, and trichothecene toxins (Wannemacher and Wiener 1997), all with different biological properties (Jarvis 1995a). Some of these growth conditions are temperature, nutritive status, light level, and growth phase. In recent years, there have been numerous reports in both the medical literature and the popular media (both print and electronic) that indoor exposure to fungi or fungal toxins has caused significant disease or death in the occupants of water-damaged homes or workplaces. These locations had signifi cant (generally visible) fungal growth and odors, typically reported as from the black mold, Stachybotrys chartarum. Cruse reported that although Stachybotrys molds have historically been speciated by morphologic criteria, their studies indicate that two separate phylogenetic species of S. What remains to be answered is whether these two subspecies produce similar toxins under similar growth conditions. Some reports of Stachybotrys related disease have involved celebrities, and these and other incidents have triggered widely publicized litigation against builders and insurance companies. A wave of lawsuits has brought mold and its potential health and economic consequences to the publics and the medias atten tion. It is named for the 9-year-old daughter of the manager of his Detroit office (The Detroit News 2002). Although not passed, this and other proposals have contributed to the publics heightened concern over mold in the indoor environment. Background on Assessing Toxicity Risk Despite the extensive attention and concern, there is no consensus in the scientific medical literature regarding toxic effects of mold as encountered by humans in non-industrial, non-farm indoor environments (Fung et al. To review the reasons for this, we will briefly review some intrinsic limitations and difficulties involved in risk identification in toxicology. Most physicians obtain their introduction to toxicology as a branch of pharmacology. We perhaps first think of toxic manifestations of drugs, which can occur as extensions of the therapeutic effects. This type of toxicity occurs most frequently with medications that have low therapeutic indices. Finally, we may think of the toxic effects of environmental agents, including heavy metals (mercury, cadmium, and lead) and airborne toxic agents (such as carbon monoxide and diesel exhaust particles). Brief consideration of the issues will lead to the conclusion that the toxicologist faces significant problems, as compared to the pharmacologist, in terms of quantify ing the relationships between the agent and the response. The data can be used to derive a rather precise and predictable log-dose response curve for most agents. In contrast, the toxicologist or epidemiologist studying clinical effects of naturally occurring toxins has none of this information and thus labors under several disadvantages. First, he or she often does not know with certainty the concentration of the toxic agent that was present in the environment when the pathology was induced.

Indapamide 2.5 mg lowest price

Limit the amount of non-disposable patient-care equipment brought into the home of patients on Contact Precautions blood pressure kits stethoscope order 1.5 mg indapamide. Whenever possible, leave patient-care equipment in the home until discharge from home care services. Alternatively, place contaminated reusable items in a plastic bag for transport and subsequent cleaning and disinfection. In ambulatory settings, place contaminated reusable noncritical patient-care equipment in a plastic bag for transport to a soiled utility area for reprocessing. Environmental measures Ensure that rooms of patients on Contact Precautions are prioritized for frequent cleaning and disinfection. Discontinue Contact Precautions after signs and symptoms of the infection have resolved or according to pathogen-specific recommendations in Appendix A. Use Droplet Precautions as recommended in Appendix A for patients known or suspected to be infected with pathogens transmitted by respiratory droplets. Draw the privacy curtain between 103, 104 410 beds to minimize opportunities for close contact. In long-term care and other residential settings, make decisions regarding patient placement on a case-by-case basis after considering infection risks to other patients in the room and 410 available alternatives. In ambulatory settings, place patients who require Droplet Precautions in an examination room or cubicle as soon as possible. Instruct patients to follow recommendations for 447, 448 9, 828 Respiratory Hygiene/Cough Etiquette. If transport or movement in any healthcare setting is necessary, instruct patient to wear a mask and follow Respiratory Hygiene/Cough Etiquette Discontinue Droplet Precautions after signs and symptoms have resolved or according to pathogen-specific recommendations in Appendix A. Use Airborne Precautions as recommended in Appendix A for patients known or suspected to be infected with infectious agents transmitted person-to-person by the airborne route. Provide at least six (existing facility) or 12 (new construction/renovation) air changes per hour. Once the patient leaves, the room should remain vacant for the appropriate time, generally one hour, to allow for a full 11, 12, 122 exchange of air. Instruct patients with a known or suspected airborne infection to wear a surgical mask and observe Respiratory Hygiene/Cough Etiquette. Personnel restrictions Restrict susceptible healthcare personnel from entering the rooms of patients known or suspected to have measles (rubeola), varicella (chickenpox), disseminated zoster, or smallpox if other immune 17, 775 healthcare personnel are available. Respiratory protection is recommended for all healthcare personnel, including those with a documented take after smallpox vaccination due to the risk of a genetically engineered virus against which the vaccine may not provide protection, or of exposure to a very large viral load. In acute care hospitals and long-term care and other residential settings, limit transport and movement of patients outside of the room to medically-necessary purposes. For patients with skin lesions associated with varicella or smallpox or draining skin lesions caused by M. Healthcare personnel transporting patients who are on Airborne Precautions do not need to wear a mask or respirator during transport if the patient is wearing a mask and infectious skin lesions are covered. Exposure management Immunize or provide the appropriate immune globulin to susceptible persons as soon as possible following unprotected contact. Discontinue Airborne Precautions according to pathogen-specific recommendations in Appendix A. The environmental recommendations in these guidelines may be applied to patients with other infections that require Airborne Precautions. No recommendation for placing patients with other medical conditions that are associated with increased risk for environmental fungal infections 11. Directed room airflow with the air supply on one side of the room that moves air across the patient bed and out through an 13 exhaust on the opposite side of the room. Positive air pressure in room relative to the corridor (pressure 13 differential of >12. Lower dust levels by using smooth, nonporous surfaces and finishes that can be scrubbed, rather than textured material. Wet dust horizontal surfaces whenever dust detected and routinely clean crevices and sprinkler heads where dust may 940, 941 accumulate. Minimize the length of time that patients who require a Protective Environment are outside their rooms for diagnostic procedures and other 11, 158, 945 activities. During periods of construction, to prevent inhalation of respirable particles that could contain infectious spores, provide respiratory protection. No recommendation for use of particulate respirators when leaving the Protective Environment in the absence of construction. Implement Droplet and Contact Precautions as recommended for diseases listed in Appendix A. Transmission-Based precautions for viral infections may need to be prolonged because of the patients 930 immunocompromised state and prolonged shedding of viruses 1010 928, 932 1011. Implement Airborne Precautions for patients who require a Protective Environment room and who also have an airborne infectious disease.
