Longitudinal studies of clinical outcomes in more highly exposed populations would allow for more definitive health assessments by increasing the statistical power of the studies and reducing concerns with the possibility of physiological confounding or reverse causality erectile dysfunction jogging buy discount super avana line. Triangulation using both prospective exposure biomarkers and careful external dosimetry would further strengthen these study findings. Such studies of large, highly exposed populations could corroborate or challenge the findings of the C8 Science Panel and other epidemiological research which forms the basis for current thinking with regard to clinical disease. One or more of these fundamental features would need to be addressed to have a significant impact on the overall body of evidence from epidemiologic studies. Using these improved methods, there would also be a need for identifying health effects with a quantitative measure of exposure levels and some form of a dose-response gradient. If research could begin to determine empirically how these mixtures of compounds act independently or together to affect health it would change the views of what to regulate, i. There is an extensive amount of toxicology literature that addresses specific chemicals and outcomes and allows for some broader conclusions. Studies of cancer are limited, but the C8 Health Project evidence supported an association with kidney and testicular cancer. While adverse reproductive effects are clear from toxicology studies, the epidemiologic studies suggest a reduction in birth weight. Toxicologic evidence indicates adverse hepatic and renal effects, with limited epidemiologic support, and there is mixed evidence regarding endocrine effects (particularly thyroid), neurodevelopment, and obesogenicity. The Panel recommends adding immunologic effects to the list of health condition of concern, particularly those that arise during prenatal exposure and childhood, and reduced birthweight, based on strong toxicology findings and supporting epidemiologic evidence. The levels vary widely between chemicals, and among the entities that issued them. Calls for global collaboration to harmonize the risk assessment and regulatory actions on this class of chemicals has emerged (Ritscher et al. These differences reflect the specific toxicological outcomes identified as critical driver for derivation of the Reference Dose (RfD) and estimates of daily water intake. The exceedingly persistent nature of these chemicals in humans must be taken into consideration for health risk assessment. This choice was challenged because reduced bone ossification reflects a developmental delay, rather than an induction of anatomical defect; however, developmental delay can reflect an overall detrimental effect of chemical exposure that lead to growth and developmental deficit in the offspring. On the other hand, advanced pubertal maturation was only seen in males and was somewhat inconsistent with a general pattern of developmental delays. However, two other toxicity outcomes evaluated (reduced immunological function in mice, and reduction of body, liver and kidney weights in a 2-generation reproductive toxicity study with rats) yielded an identical RfD (20 ng/kg/day). To provide additional protection for breastfeeding infants, the risk assessors assumed a more conservative water intake estimate of 0. Minimal risk levels are analogous to reference doses and follow similar derivation procedures. As shown above, even based on an identical critical effect that drives the risk evaluation, a different set of drinking water values can be derived from various assessors. Hence, interpretation of a specific numerical drinking water values from various health advisories can be subject for debate, until an enforceable limit is available after formal regulatory determinations by the federal or state government. Consideration of the epidemiological findings suggests that human health effects may occur at exposures within this range of drinking water values as discussed later in this report. No relative source contribution is included (assumes all exposure is from drinking water) 50 Table 4. It has been used as a chemical exposure metric in assessing risk of cancer or other chronic health conditions. Pharmacokinetic models (also called toxicokinetic or biokinetic models) are used to represent the quantitative relationship between specific water concentrations and the resulting human serum concentrations over time. These models require knowledge regarding several key physiological and behavioral characteristics including the excretion half-life of the chemical, the extent to which it is absorbed and distributed among various bodily tissues after ingestion, and the water ingestion rate. Because these characteristics may vary among individuals and are often difficult to measure, the models are most often used to represent the average relationship between environmental concentrations and serum concentrations for populations, rather than making specific predictions for individuals. For upper percentile water ingestion, the estimated cumulative serum concentration is 1300 ng/ml-years. Nonetheless, if the parameters are wrong then these models may produce estimates that are somewhat too low or too high. For example, several publications have reported human half-lives slightly longer than 2. Because the half-life and other parameters are intertwined, a longer half life might result in a different estimate of the steady-state serum to water concentration ratio, and slightly different serum predictions. Nonetheless, a close agreement among different models suggests that the calculations can be useful in translating drinking water exposures to serum concentrations for comparison to the epidemiological literature. This is important because it indicates that this level of exposure would result in being in the top quartile, quintile, or decile of exposure in epidemiological studies of the general population. For some epidemiological studies, cumulative serum concentrations have been used to characterize exposure instead of serum concentrations at a single time point. For testicular cancer, incidence was increased by 4% and 91%, respectively, in the second and third quartiles. Thyroid cancer was similar elevated, but with less precise effect estimates and weaker evidence of a dose-response relationship. These cumulative exposures fall near the top of the second quartile or bottom of the third quartile of exposure for the C8 Science Panel cohort; the second quartile was 219-812 ng/Ml-years for kidney cancer and 150-876 ng/ml-years for testicular cancer. Again, the implication of this comparison is that one must infer that the cancer associations reported in this study (and in the similar study by Vieira et al. Three such studies appear to be available, showing a remarkable consistency despite different primary exposure pathways, study designs, and methods of exposure quantitation (Table 5). Study Exposure Source; Equivalent Exposure Effect Estimate (95% Quantification Category for 70 ppt Confidence Interval) Steenland et al. The limitations in this approach must also be acknowledged, starting with the inherent uncertainty in a limited body of research from a single study population as in the C8 Health Project. Random error and bias were addressed to the extent feasible, but nonetheless, some or all of the associations may not reflect causal effects. The quantification of risk is also subject to uncertainty, with some uncertainty in reconstructing exposure and inferring water consumption levels to derive risk estimates. High quality toxicology experiments use randomized experiments under carefully controlled laboratory conditions, which increases confidence for inferring causation, but laboratory animals are not humans (despite many similarities in mammalian physiology across species). Epidemiology studies, on the other hand, must rely on natural experiments or other observational data rather than randomized experiments, which makes it much more difficult to rule out confounding or other sources of bias and infer causation. Hertz-Picciotto (1995) proposed influential guidelines for determining when epidemiological data are sufficient for risk assessment, including criteria for individual level exposure quantification, limited potential for confounding and other bias, and clearly elevated risk. Finally, some authors have recommended that animal and human dose-response information be combined quantitatively using formal methods, rather than choosing one or the other, when high quality studies of both types are available (Samet et al. This approach has not yet, to our knowledge, been used to set drinking water limits. The differences in these recommended limits reflect selection of different health outcomes, or different assumptions regarding water consumption rates or lactational transfer. The pharmacokinetic models used to link serum concentrations in these animal studies to human doses can also be used to determine the serum concentration expected to result in humans. Increases in ulcerative colitis, some cancers, and other health effects have reported for those exposure categories. The epidemiologic evidence that supports health effects from the serum levels produced by long-term exposure to 70 ppt pertains to developmental immunologic outcomes as well as adult diseases evaluated by the C8 Science Panel and are supported by the toxicology studies. Their log Koc (organic carbon-water partitioning coefficient) values range from 1 to 230; chemicals with higher Koc values will tend to move into the organic matter on soils and biosolids, whereas compounds with low Koc will have stronger associations with (and will be more mobile in) water. The charge of the compound is important as it will affect whether it is in air, water, or on a solid surface, how it is transported into an organism, and the efficacy of a remediation strategy. However, more recent research suggests that the Koc values for these compounds depend more on chain length than whether the chemical contains sulfonic acid or carboxylic acid groups (Rayne and Forest, 2009). Compounds with a high log Koc (usually those with longer chains) are more effectively removed by adsorption onto activated carbon thank those with a low log Koc. Among the challenges in measuring efficiencies are an inability to quantify these chemicals or to identify their byproducts analytically along with unknown or unmeasurable losses of the chemical to the air and solid.

The exposed nerves are damaged can you get erectile dysfunction young age buy super avana once a day, leaving the child with varying degrees of paralysis, incontinence, and sometimes mental retardation. Some women are at an increased risk for having a baby with an open neural tube defect. These women include, but are not limited to , those with a family history of spina bida and those taking anti-epileptic medicines. Your doctor can discuss this with you and, in some cases, refer you for genetic counseling. Public Health Service recommends that all women of childbearing age get 400 micrograms of folic acid each day. There are natural sources of folic acid: green leafy veg etables, nuts, beans, and citrus fruits. Taking calcium during pregnancy can prevent a new mother from losing her own bone density as the fetus uses the mineral for bone growth. While a daily vitamin supplement is no substitute for a healthy diet, most pregnant and lactating women need supplements to make sure they get adequate levels of these minerals. All rights reserved 13 Medicine Guidelines During Pregnancy Although some medicines are considered safe during pregnancy, the effects of other medicines on your unborn baby are unknown. Certain medicines can be most harmful to a developing baby when taken during the rst three months of pregnancy, often before a woman even knows she is pregnant. Prescription medicine guidelines If you were taking prescription medicines before you became pregnant, please ask your health care provider about the safety of continuing these medicines as soon as you nd out that you are pregnant. Your health care provider will weigh the benet to you and the risk to your baby when making his or her recommendation about a particular medicine. With some medicines, the risk of not taking them might be more serious than the potential risk associated with taking them. For example, if you have a urinary tract infection, your health care provider might prescribe an antibiotic. If the urinary tract infection is not treated, it could cause long-term problems for both the mother and her baby. If you are prescribed any new medicine, please inform your health care provider that you are pregnant. Be sure to discuss the risks and benets of the newly prescribed medicine with your health care provider. Ask your health care provider about the safety of taking other vitamins, herbal remedies, and supple ments during pregnancy. Most herbal preparations and supplements have not been proven to be safe when taken during pregnancy. Generally, you should not take any over-the-counter medicine unless it is necessary. The following medicines and home remedies have no known harmful effects during pregnancy when taken according to the package directions. If you want to know about the safety of any other medicine not listed here, please contact your health care provider. The results of the test remain a part of your medical records and are treated the same way as any other part of your medical record. Your decision whether to get tested and/or the test result itself will not prevent you from getting health care. Therefore, if you have a neg ative test during your pregnancy, it will likely prevent testing on your baby after birth. All rights reserved Index# 4849 20 Screening for Chromosome Abnormalities in Pregnancy Cleveland Clinic offers options for women who are interested in determining the risk for chromosome abnormalities and certain birth defects in their baby during a pregnancy. These tests allow patients the opportunity early in pregnancy to nd out if their baby has one of these conditions. Having this testing performed is optional and should only be done after a thorough discussion of available tests. In some instances, your provider may refer you for genetic counseling to see which, if any, test is best for you. Sequential Screening the sequential screen combines ultrasound and blood tests to determine the risk for chromosome abnormalities, including Down syndrome (Trisomy 21) and Trisomy 18. The nuchal translucency is a uid lled space behind the neck, which is typically increased in size in fetuses with Down syndrome, other chromosome abnormalities, and birth defects. This women with risk factors for having a includes a baby with chromosomal new test called non-invasive abnormalities. This test detects ultrasound 75 to 80 percent of cases of Down -Previous history of a syndrome and 60 to 75 percent of chromosome abnormality cases of Trisomy 18, with a 5 to 7 percent false positive rate. All rights reserved Index# 15187 23 Prenatal Ultrasonography What is ultrasonography In ultrasonography, or ultrasound, high-frequency sound waves are sent through your abdomen by a device called a transducer. The sound waves are recorded and changed into video or photographic images of your baby. The ultrasound can be used during pregnancy to show images of the amniotic sac, placenta, and ovaries. The idea for ultrasonography came from sonar technology, which makes use of sound waves to detect underwater objects. Ultrasound might be used with other diagnostic procedures, such as amniocentesis, or by itself. Transvaginal ultrasound Most prenatal ultrasound procedures are performed on the surface of the skin, using a gel as a conductive medium to aid the quality of the image. However, a transvaginal ultrasound is performed using a probe that is in serted into the vaginal canal. A transvaginal ultrasound may be used early in pregnancy to determine how far along you are in your pregnancy (gestational age) if this is uncertain or unknown. It may also be used to get a clearer view of the uterus or ovaries if a problem is suspected. Ultrasound An ultrasound is generally performed for all pregnant women at 20 weeks gestation. During this ultrasound, the doctor will evaluate if the placenta is attached normally, and that your baby is growing properly in your uterus. If you wish to know the gender of your baby, it can usually be determined at 20 weeks. Be sure to tell the ultrasound doctor whether or not you want to know the gender of your baby. There is a chance that 25 the ultrasound images can be During the test misinterpreted. An ultrasound You will lie on a padded examining might be performed earlier in your table during the test. A small device, called a transducer, Later in pregnancy, ultrasound is gently applied against the skin on might be used to determine: your abdomen. Even though ultrasound There is virtually no discomfort is safe for mother and baby, it is a during the test. If a full bladder is test that should be done only when required for the test, you might feel medically necessary. If you have an some discomfort when the probe is ultrasound that is not medically nec applied. You might be asked to hold essary (for example, to simply see the your breath briey several times.

Direct antagonism between lactic acid When the calf fnishes drinking, rub a little bacteria and the pathogenic bacteria. This is commonly done through palatable, coarse-textured, high in energy milk replacer feeding. However, there is also research showing the failure of probiotics to produce benefcial effects. Calves can be weaned once they are c) the bacteria fail to competitively exclude consistently consuming 1kg of concentrates harmful bacteria. Prebiotics A number of feed additives can be added to Prebiotics are carbohydrates which are not calf rations to help improve calf digestion, broken down in the small intestine. They are health and support optimum growth and fermented in the large intestine, acting as a performance. Mannanoligosaccharides and glucan are commonly used prebiotics that are able to I. Probiotics prevent pathogenic bacteria sticking to the lining of the digestive tract. Prebiotics can also Probiotics are live bacteria that are fed to , and decrease the coliform numbers in the large beneft, the animal through improvements in intestine and colon of calves. Feeding benefcial lactic acid bacteria is thought to inhibit the Through these mechanisms, prebiotics can growth of pathogenic bacteria by: improve average daily gain and reduce faecal 68 13 E. Yeast products There are two types of yeast products on the market: live yeast products and yeast cultures. Live yeast products contain viable yeast (such as Saccharomyces cerevisiae) and the media on which the yeast is grown. It is claimed they stimulate rumen fermentation and bacterial growth, and thereby increase dry matter intake and consequently improve animal performance. However some research studies have found only limited effects of yeast on both intake and gain effciency. This suggests that the response of calves to yeast cultures can be both variable and inconsistent. Yucca extract Yucca extract is prepared by processing the cactus plant Yucca schidigena. Yucca inclusion in the diet of pigs and poultry is common practice with a signifcant reduction in ammonia levels found. For calves, the inclusion of Yucca extract in their diet can improve rate of gain and feed effciency. This may be due to the reduction of rumen fuid ammonia levels and increases in microbial growth, resulting in increased microbial protein synthesis and increased protein availability in the small intestine. Water consumption is important for the development of the rumen and to allow for timely weaning of calves off milk. Ruminants require quality fbre in the diet to maximise production and maintain health by sustaining a stable environment within the rumen. If the calves you are rearing are to achieve maximum milk or beef production from pasture, then the importance of setting the rumen up for life with quality fbre early cannot be overemphasised. This water goes directly into the leads to a 56g increase in weight gain per rumen and creates the ideal environment day. Separation improves both starter and Better starter Improved grain water consumption. As a minimum, the water should Research has shown that calves that have free be tested annually for minerals, nitrates, access to water eat more starter concentrates total dissolved solids and pH, as well as and have enhanced rumen development. The ideal time for hay or straw to be introduced depends on the type of starter concentrates that you are feeding. In particular, if fne ground pelleted rations are fed, additional roughage will be necessary to aid the development of the rumen. In general, fbre/roughage may be introduced by day three and should be available to all calves by two weeks of age. In this situation, the rumen is stuffed with hay which cannot be properly digested and rumen development is delayed. Poor quality fbre creates a fll effect, especially if long stemmed, and is indigestible to a young calf. Studies have shown that providing pre-weaning calves with a chopped forage source separately to starter concentrate, such as oat or ryegrass hay, triticale silage and barley straw, improves their average daily gain, fnal bodyweight at weaning and their starter intake compared to calves not receiving forage and those receiving alfalfa hay.

He was brought up in Austrian Trieste, studied medicine in Vienna, and in 1906 took a post in the Psychiatric Clinic under Professor Julius von Wagner-Jauregg. In 1916 during World War I, he began seeing cases of a new and previously unrecorded type of encephalitis and published his rst report of this illness in 1917. Although subsequent accounts have often confused this illness with the epidemic of inuenza that swept through Europe and then the rest of the world during World War I, von Economo was quite clear that encephalitis le thargica was not associated with respiratory symptoms, and that its appearance preceded the onset of the latter epidemic. Von Economo continued to write and lecture about this experience for the remainder of his life, until his premature death in 1931 from heart disease. Based on his clinical observations, von Economo proposed a dual center the ory for regulation of sleep and wakefulness: a waking inuence arising from the upper brainstem and passing through the gray matter surrounding the cerebral aqueduct and the posterior third ventricle; and a rostral hypothalamic sleep promoting area. These observations became the basis for lesion studies done by 20 21 22 Ranson in 1939, by Nauta in 1946, and by Swett and Hobson in 1968, in which they showed that the posterior lateral hypothalamic lesions in monkeys, rats, and cats could reproduce the prolonged sleepiness that von Economo had observed. The rostral hypothalamic sleep-promoting area was conrmed exper 21 imentally in rats by Nauta in 1946 and in cats by Sterman and Clemente in the 23 1960s.

These indi viduals would develop episodes of sleep attacks during which they had an over whelming need to sleep. He noted that they also had attacks of cataplexy in which they lost all muscle tone, often when excited emotionally. Von Economo noted accurately that these symptoms were similar to the rare condition previously identied by Gelinaux as narcolepsy. He also noted that they had developed symptoms of narcolepsy after recovering from encephalitis lethargica with pos terior hypothalamic lesions. Wilson even described examining a patient in his ofce, with the young house ofcer McDonald Critchley, and that the patient indeed had atonic paralysis, with loss of tendon reexes and an extensor plantar response during the attack.

The stomach has a storage capacity of 1/2 to 1 liter erectile dysfunction treatment natural remedies purchase super avana 160mg on-line, the exact reservoir size depending on the degree of stretching of the convoluted walls. These convolutions are called rugae, which are the macroscopic folds observed in dissection of the stomach. The rugae, which run predominantly longitudinally, are upthrusting folds of the submucosa upon which is draped the entire mucosa. Examination of the stomach mucosa with the Virtual Microscope at fairly low magnification reveals that the surface epithelium is not smooth, but is folded into mucosal glands (illustrated in Figures 2B, 4B, 4C, and 4D). The folding pattern of these glands is unique to the stomach and therefore key to identifying the stomach in Virtual Microscopy sections. Specifically, the stomach mucosal glands can be divided into two distinctive regions: gastric pits and gastric glands. The fairly wide gastric pits extend from the lumen into the lamina propria, about 1/4 to 1/3 of the way to the muscularis mucosae. At the base of the wide pits the epithelium turns into gastric glands, which are narrower in diameter than the pits and extend down to the muscularis mucosae (Figures 4B and C). Simple columnar epithelium lines the surface of the pits and glands throughout the stomach (Figure 4D). All of the surface cells in the pits produce a mucous secretion and are therefore referred to as mucous surface cells (Figure 4D). These rectangular mucous surface cells are different from the goblet cells seen in the intestinal epithelium, which are distended apically (hence the term goblet) by their secretory product. The mucous surface cells differ in appearance from the mucous neck cells of the glands in the lamina propria, because there is often less secretory product visible in the cytoplasms of the neck cells (Figure 4D). However, the types of epithelial cells in the glands vary, depending on the region of stomach, as described in the next section. Progressing clockwise from A to D are schematic representations at increasing magnifications of the stomach, stomach wall, mucosal glands, and a gastric (fundic) gland. These main gastric glands are tubular glands that run perpendicular to the lumenal surface, extending from the base of the gastric pits to the muscularis mucosae-they are 2-3 times as deep as the pits. As shown in Figure 4D, in these main gastric glands the epithelium of the isthmus, neck and base contains four types of cells, not evenly distributed: (1) Mucous neck cells, found primarily in the neck (top) of the gland, are thought to produce a slightly different secretion from the mucous surface cells. They probably also release A and B blood-group substances which are thought important in the protection of the mucosal surface, since type 0 individuals are more prone to ulcers. They are large rounded cells found in the neck and isthmus, and, to a smaller extent, in the base of the gland. They are characterized by an elaborate intracellular system of membranous channels or canaliculi and by a profusion of mitochondria. Because they produce pepsinogen, a precursor to pepsin, these are often called zymogenic cells. However, in your Webslides their secretory granules are not as obvious as those of pancreatic acinar cells. Occasionally chief cell granules appear somewhat pale, suggesting that the cells are intermediate in the serous-mucous spectrum. The chief cells also produce rennin (the enzyme present in infants which curdles milk) and probably other enzymes, among them a lipase. That is, because endocrine cells secrete into the underlying connective tissue (and not into the lumen of the gland), the nucleus is often located near the apex of the cell and secretion granules are situated between the nucleus and the basal lamina. The apices of these cells may or may not be in continuity with the glandular lumen. Endocrine cells secrete hormones into the blood stream, whereas paracrine cells secrete substances that act on neighboring cells. That is, paracrine secretions do not have to enter the blood stream, but rather diffuse through the connective tissue to act locally. The mucosal glands of the cardiac and pyloric regions of the stomach are different from these main gastric glands (Figure 4C). The cardiac glands, which only occur over an area of about 10-15 cm2 centered on the gastro-esophageal junction and can sometimes be found in the lamina propria of the distal esophagus, are shorter and more branched than the fundic glands. The cardiac glands contain mostly mucous cells, with few chief cells and virtually no parietal or 9 Normal Body 2015 endocrine cells. Over the approximately 15% of the stomach mucosa centered on the pyloric sphincter are pyloric glands, whose gastric pits are deeper and whose glands are often more coiled and branching than the main gastric glands. Although in humans the pyloric glands contain a few parietal cells, there are essentially no chief cells, the main type being a cell with a rather pale, apparently mucous-containing cytoplasm. These pyloric glands do contain endocrine cells, which produce the polypeptide hormone gastrin. Gastrin is released into the circulation when food enters the stomach and stimulates release of the acid secretions of the main gastric gland-a stimulation that is counteracted when the acidity of the stomach contents gets too high. Because the stomach mucosa is packed with glandular epithelium, the lamina propria is not obvious as a continuous layer, being found essentially as thin strands between the glands. The muscularis mucosae is prominent in the stomach as a distinct layer delimiting the bases of the mucosal glands. Elastic fibers of the submucosa account for the stretch ability of these folds and thus the dispensability of the stomach. In the cardiac region there is an additional, innermost, layer of obliquely oriented smooth muscle fibers, which is scanty elsewhere in the stomach and often difficult to see in a given histological preparation. In the stomach, the middle layer of circularly oriented smooth muscle is thickened at the juncture between the pyloric stomach and the small intestine (duodenum) forming the pyloric sphincter. Food, having traversed the esophagus rapidly, spends a few minutes to a few hours within the stomach. The most vigorous mixing occurs in the pyloric antrum and the longitudinally oriented rugae tend to funnel the food, repeatedly displaced upward by the churning of the muscularis, back down to the pylorus. Exposure to the acid mixture of gastric enzymes converts the fairly solid ingesta into a creamy semi-solid mass called chyme, which, in small portions, is passed through the pyloric sphincter to the duodenum. While food is thus at least partially digested in the stomach, little absorption takes place there, with the exceptions of water and alcohol. Although these preprocessing operations are highly useful, they are not indispensable, since persons with total gastrectomy seem to function quite well. This acidity, which is entirely due to the actions of the parietal cells, poses severe problems for the gastric mucosa-problems that appear to have been solved by extensive overproduction of mucous material which coats and protects the epithelium. Nevertheless, the wear and tear on the epithelium of the gastric mucosa is significant and there is extensive cell turnover. The mucous surface cells seem to be replenished by virtue of mitotic activity in the isthmus regions of the fundic glands, but the turnover of parietal and chief cells is less well understood. With regard to the recognized connection between tension (or anxiety) and ulcers, you should realize that the control of gastric secretion (which can range from a basal rate of 10 Normal Body 2015 about 10 ml/hr to more than 100 ml/hr) involves an initial cephalic phase (psychic factors including emotional state, sight and smell of food, etc. Small Intestine the partially digested food (chyme) passes through the pyloric sphincter and into the small intestine (Figure 5). This is a tube some 7 meters long in humans consisting of, in proximo distal order, the duodenum (about 25 cm), the jejunum (2. In the small intestine the degradative phase of digestion is essentially completed and most absorption of nutrients occurs. Accordingly the mucosa is highly specialized, primarily for absorption, but also for secretion. To facilitate absorption, the intestinal wall has a very large surface area due to the folding of the mucosal elements at three levels; (1) the entire mucosa is thrown into deep folds called plicae circulares, which run circumferentially or spirally (upper right hand panel of Figure 5A). Plicae begin in the distal duodenum, reach maximal size in the jejunum, begin to diminish in the ileum, and are nearly absent in the distal ileum.
