Similar in structure to glycogen (the major form of polysaccharide in animals) order discount dilantin on-line medicine and manicures, it makes up as much as 20% of the starch in the diet buy generic dilantin on-line medicine 2410. The glucose-to-glucose bridge is of the alpha type in contrast to the beta type buy cheap dilantin on line treatment quadriceps pain, which connects glucose units in cellulose, an indigestible saccharide. These non-starch polysaccharides provide most of the unavailable carbohydrate in the diet, mainly as dietary fibers, (e. Cellulose is comprised of non digested -1,4-linked glucose in straight chains, and hemicelluloses is comprised of polymers of pentose and hexose with straight as well as branched chains. Other dietary fibers such as pectins, gums and alginates that may First Principles of Gastroenterology and Hepatology A. Dietary fibers are active molecules that play an important role in altering the luminal content and mass, transit time and absorption of some nutrients. The remaining 80% of the starch that humans ingest has a branch point every 25 molecules along the straight -1,4 glucose chain. The action of pancreatic -amylase on linear (amylose) and branched (amylopectin) starch. Salivary amylase acts in the mouth where slow chewing improves its action, while gastric acid leads to rapid inactivation of salivary amglose. Pancreatic amylase is the major enzyme of starch digestion and acts mainly within the intestinal lumen. These are called limit dextrins, and represent about 30% of amylopectin breakdown. The end products of amylase hydrolysis therefore are not single glucose molecules. They are present in highest concentration at the villous tips in the jejunum, and persist throughout most of the ileum, but not in the colon. Maltase-Glucoamylase differs from pancreatic -amylase First Principles of Gastroenterology and Hepatology A. Shaffer 186 since it sequentially removes a single glucose from the nonreducing end of a linear -1,4 glucose chain, breaking down maltose into glucose.

In contrast, increasing the dietary load does not up-regulate manipulation can regulate the activities of lactase or maltase. Disaccharidase enzymes are glycoproteins that are synthesized as proenzymes in the rough endoplasmic reticulum, then pass through the Golgi complex of the crypt and villus enterocytes for further processing. In normal adult small intestine, these enzymes are expressed in the more well-differentiated villous cells compared to crypt cells and their activities are greater in the proximal compared to distal small intestine. Sucrase-isomaltase is encoded by a single gene located on chromosome 3 at locus 3q-25-26 while the lactase gene is located on the long arm of chromosome 2. A single missense mutation in amino acid 28 (aspartate asparaginase) is + responsible for familial glucose-galactose malabsorption. Shaffer 188 molecule of glucose, about 1100 molecules of water also cross the epithelium to maintain 150-osmolarity of the absorbate). Primary lactase deficiency is very common in certain ethnic groups, such as persons from South East Asia, and may limit the intake of milk in some adults. Secondary Deficiency of disaccharidases results from anatomic injury of the small intestine, as in celiac disease, tropical sprue and gastroenteritis. When disaccharidase levels are sufficiently low, the particular oligosaccharide or disaccharide remains unhydrolyzed within the intestinal lumen, and augments intraluminal fluid accumulation by virtue of its osmotic effect. Intermediate and end products of anaerobic bacterial fermentation of carbohydrates. First, reabsorption of fatty acids and alcohols in the colon salvages First Principles of Gastroenterology and Hepatology A. Second, this colonic salvage reduces the number of osmoles of the solutes in the lumen, and hence lessens the water lost in feces. Although infants have a relative deficiency of amylase, starch is not fed for the first few months of life. In the adult, there is a great excess of pancreatic amylase secreted into the intestinal lumen, so that even in patients with severe fat malabsorption due to pancreatic exocrine insufficiency, residual salivary and pancreatic amylase output are usually sufficient to completely hydrolyze starch by the time a meal reaches the mid-jejunum. Digestion and Absorption of Peptides and Amino Acids Derived from Protein An average adult consumes about 70 g of protein daily. About half of the protein in the intestine is derived from endogenous sources, such as salivary, gastric and pancreatobiliary secretions, desquamated mucosal cells and exudated plasma proteins. Pepsinogen release from gastric chief cells is stimulated by gastrin, histamine and acetylcholine. Pepsins are derived from precursor pepsinogens; autoactivation of secreted pepsinogens in the acidic pH with loss of a small basic peptide, producing pepsin. Pancreatic amylase is secreted in an active form, but pancreatic proteases are secreted as proenzymes that require luminal activation. Trypsin, in turn, activates other proteases, and autocatalyzes its own further activation from trypsinogen. Sequence of events leading to hydrolysis of dietary protein by intraluminal proteases. Most peptidases are aminopeptidases that remove an amino acid residue from the peptide amino terminus. Because of this alternate small peptide pathway, patients with inherited basic or neutral aminoacidurias (e. A single hydrogen ion is transported with peptide by a hydrogen-peptide cotransporter (hPepT1). Passive Permeation The epithelium of the small intestine exhibits a high passive permeability to salt and water that is a consequence of the leakiness of the tight junctions between epithelial cells. The ileum is less permeable to ions than is the jejunum, and the colon is even less permeable with First Principles of Gastroenterology and Hepatology A. In the small intestine most water absorption occur as the result of carrier-mediated transport of solutes. Osmotic equilibration between plasma and lumen is rapid; as a result, large differences in ion concentration do not really develop. Water and some small water-soluble solutes can pass across the mucosal barrier formed by the enterocytes. Persons with intestinal secretory diseases such as cholera + absorb glucose normally. Na (and thus water) are also absorbed with glucose, so that the secretory fluid losses incurred by these patients can be replaced by oral glucose-electrolyte solutions (e. In addition to sugar, many amino acids, certain B vitamins and bile salts are absorbed through this mechanism. Nutrient-Independent Nutrient-independent active absorption of electrolytes and water by intestinal epithelial cells occurs through mechanisms located along the small and large intestine.

Most of the food we eat is turned into glucose, or sugar, for our bodies to use for energy. The pancreas, an organ that lies near the stomach, makes a hormone called insulin to help glucose get into the cells of our bodies. Risk factors are less well defined for Type 1 diabetes than for Type 2 diabetes, but autoimmune, genetic, and environmental factors are involved in the development of this type of diabetes. Type 2 diabetes may account for about 90 percent to 95 percent of all diagnosed cases of diabetes. African Americans, Hispanic/Latino Americans, American Indians, and some Asian Americans and Pacific Islanders are at particularly high risk for type 2 diabetes. Gestational diabetes develops in 2 percent to 5 percent of all pregnancies but usually disappears when a pregnancy is over. Gestational diabetes occurs more frequently in African Americans, Hispanic/Latino Americans, American Indians, and people with a family history of diabetes than in other groups. Women who have had gestational diabetes are at increased risk for later developing Type 2 diabetes. In some studies, nearly 40 percent of women with a history of gestational diabetes developed diabetes in the future. Such types of diabetes may account for 1 percent to 2 percent of all diagnosed cases of diabetes. Approximately 40 percent of people with type 2 diabetes require insulin injections. A number of studies have shown that regular physical activity can significantly reduce the risk of developing type 2 diabetes. In response to the growing health burden of diabetes mellitus (diabetes), the diabetes community has three choices: prevent diabetes; cure diabetes; and take better care of people with diabetes to prevent devastating complications.

Successful Salvage of Sildenal (Sildenal) Failures: Benets of Patient Education and Re-Challenge with Sildenal. Presented at the 4th Congress of the European Society for Sexual and Impotence Research, Sept. Sildenal failures may be due to inadequate instructions and follow-up: a study of 100 non-responders. It encourages the belief that sexually healthy women agree to sex or initiate it mostly because they are aware of sexual desirebefore any sexual stimulation begins. Indeed, this is in accordance with the traditional model of human sexual responding of Masters, Johnson, and Kaplan. As we will see, this conceptualization contradicts both clinical and empirical evidencewomen in established relationships infrequently engage in sex for reasons of sexual desire (16). That sense of desire, or need, or hunger is nevertheless felt once subjectively aroused/excited. When that arousal is insuf- cient or not enjoyed, motivation to be sexual typically fades. In other words, although not usually the prime reason for engaging in sex, enjoyable subjective arousal is necessary to maintain the original motivation. So, lack of subjective arousal is key to womens complaints of disinterest in sex. This imprecision presents a major dilemma to both clin- icians and the women requesting their help. Any formulation of a hypoactive sexual desire/interest disorder must take into account the normative range of womens sexual desire across cultures (7), age, and life cycle stage (8). Desire for sex typically lessens with relationship duration and increases with a new partner (6). Womens sexual enjoyment and desire for further sexual experiences were acknowledged early last century. Before that time, there had been variable denial or intolerance and endeavors to curb womens sexuality. Unfortunately, sub- sequent to that acknowledgement, came the assumption that womens sexual function mirrors mens experiences. Female Hypoactive Sexual Desire Disorder 45 arousal is not simply a matter of genital vasocongestion. The only published randomized controlled trial using physiological (or at least close to physiological) testosterone supplementation did not result in any increased desire as in having sexual thoughts, over and beyond placebo, but did show increased pleasure and orgasm intensity and frequency. Subjective arousal was not reported, but, given the improvement in pleasure and orgasmic experiences, its improvement is implied (25). To identify reasons women willingly initiate/agree to sexwith a view to understanding why some do not. To review a model of sexual response that permits motivations (reasons/incentives), for being sexual, over and beyond sexual desire. To clarify that it is the womans arousability (along with the usefulness of sexual stimuli and context) that determines whether she will access sexual desire. In other words, for women, the concept of responsive desire or desire accessed during the sexual experience may be as or more important than initial desire as measured by sexual thoughts and sexual fantasies. To critique the traditional markers of sexual desire as they apply to womenand the questionable relevance of their lack. To outline the assessment of low desire and the associated low arousa- bility, thereby identifying therapeutic options. To review what is known of the biological basis of womens sexual desire and arousability, including the role of androgens. To review psychotherapy, pharmacotherapy, and the biopsychosexual approach to the management of womens lack of sexual interest/desire. Further reasons include increasing the womans sense of well being, of attractiveness, womanlinesseven to feel more normal (26). Simply wanting to share something of herself that is very precious, to sense her partner as sexually attractive (be it his/her strength and power, or ability to be tender/considerateor both), are further reasons. Incen- tives that might supercially appear unhealthy are also common, for example, to placate a needy (and increasingly irritable) partner (26), or do ones duty. The concept of rewards or spin offs from being sexual is currently being empirically researched. The degree of emotional intimacy with her partner that may have even been the major motivating force, is also a very important inuence on her arousability to the sexual stimuli. Various other psychological and biological factors will inuence this arousability such that the processing of the sexual information in her mind may or may not lead to subjective arousal (2731). This accessed or triggered sexual desire and the subjective arousal continue together, each reinforcing the other (32,33). A positive outcome, emotionally and physically, increases the womans motivation to be sexual again in the future (32). Sexual desire that appears to be innate or spontaneous and reected by sexual thoughts/fantasies, awareness of wanting sexual sensations per se before any activity actually begins, may or may not augment or sometimes over- ride the previously described cycle (Fig. Typically, women are more aware of this type of initial desire early on in their relationships (6). Some would argue that there is no such thing as apparent innate or spontaneous desire (26). This presupposes that desire is always part of arousal, triggered by a stimulus with a sexual meaning. A positive outcome emotionally and physically allows sexual satisfaction (goal set enroute) plus other rewards that motivated initially.

It doesnt stop you leading your normal life but makes everything harder to do and seem less worthwhile. At its most severe, depression can be life-threatening because it can make you feel suicidal or simply give up the will to live. We all have times when our mood is low, and were feeling sad or miserable about life. But if the feelings are interfering with your life and dont go away after a couple of weeks, or if they come back over and over again for a few days at a time, it could be a sign that youre experiencing depression. It starts as sadness then I feel myself shutting down, becoming less capable of coping. If you are given a diagnosis of depression, you might be told that you have mild, moderate or severe depression. This describes what sort of impact your symptoms are having on you currently, and what sort of treatment youre likely to be offered. You might move between different mild, moderate and severe depression during one episode of depression or across different episodes. See Minds booklet Understanding postnatal depression (and other perinatal problems) for more information. Sometimes it feels like a black hole but sometimes it feels like I need to cry and scream and kick and shout. Sometimes I go quiet and lock myself in my room and sometimes I have to be doing something at all times of the day to distract myself. There are many signs and symptoms of depression, but everyones experience will vary. This section covers: common signs and symptoms of depression psychotic symptoms self-harm and suicide anxiety depression as a symptom of other mental health problems. I had constant low mood, hopelessness, frustration with myself, feeling like I could cry at any moment. About psychotic symptoms If you experience an episode of severe depression, you might also experience some psychotic symptoms. These can include: delusions, such as paranoia hallucinations, such as hearing voices. If you experience psychotic symptoms as part of depression, theyre likely to be linked to your depressed thoughts and feelings. For example, you might become convinced that youve committed an unspeakable crime. These kinds of experiences can feel very real to you at the time, which may make it hard to understand that these experiences are also symptoms of your depression. They can also be quite frightening or upsetting, so its important to seek help and support. You might feel worried that experiencing psychotic symptoms could mean you get a new diagnosis, but psychosis can be a symptom of depression. Discussing your symptoms with your doctor can help you get the right support and treatment. About self-harm and suicide If you are feeling low, you might use self-harming behaviours to cope with diffcult feelings. Although this might make you feel better in the short term, self-harm can be very dangerous and can make you feel a lot worse in the long term. When youre feeling really low and hopeless, you might fnd yourself thinking about suicide. Whether youre only thinking about the idea, or 6 7 Understanding depression actually considering a plan to end your life, these thoughts can feel diffcult to control and very frightening. If youre worried about acting on thoughts of suicide, you can call an ambulance, go straight to A&E or call the Samaritans for free on 116 123 to talk. See Minds online booklet How to cope with suicidal feelings for more information. Some symptoms of depression can also be symptoms of anxiety, for example: feeling restless being agitated struggling to sleep and eat. If you think youre experiencing other symptoms, you can talk to your doctor about this to make sure youre getting the right treatment to help you. See Minds booklet Seeking help for a mental health problem for information on how to make sure your voice is heard, and what you can do if youre not happy with your doctor. It can vary a lot between different people, and for some people a combination of different factors may cause their depression. In this section you can fnd information on the following possible causes of depression: childhood experiences life events other mental health problems physical health problems genetic inheritance medication, drugs and alcohol sleep, diet and exercise. As antidepressants work by changing brain chemistry, many people have assumed that depression must be caused by changes in brain chemistry which are then corrected by the drugs. Some doctors may tell you that you have a chemical imbalance and need medication to correct it. But the evidence for this is very weak, and if changes to brain chemistry occur, we dont know whether these are the result of the depression or its cause. This could be: physical, sexual or emotional abuse neglect loss of someone close to you traumatic events unstable family situation.
