Eating a high carbohydrate diet will ensure maintenance of muscle and liver glyco- gen (storage forms of carbohydrate) buy generic oxybutynin 5mg on line, improve performance and delay fatigue buy oxybutynin 2.5mg amex. Thus, carbohy- drates are a group of polyhydroxy aldehydes, ketones or acids or their derivatives, together with linear and cyclic polyols. Most of these com- pounds are in the form CnH2nOn or Cn(H2O)n, for example glucose, C6H12O6 or C6(H2O)6. Monosaccharides These carbohydrates, commonly referred to as ‘sugars’, contain from three to nine carbon atoms. Most common mono- saccharides in nature possess five (pentose,C 5H10O5) or six (hexose, C6H12O6) carbon atoms. For example, glucose, a six-carbon-containing sugar, is the most common monosaccharide that is metabolized in our body to provide energy, and fructose is also a hexose found in many fruits. Di-, tri- and tetrasaccharides These carbohydrates are dimers, trimers and tetramers of monosaccharides, and are formed from two, three or four monosaccharide molecules, with the elimination of one, two or three molecules of water. For example, sucrose is a disaccharide composed of two monosaccharides, glucose and fructose. Oligosaccharides The name ‘oligosaccharide’ refers to saccharides con- taining two to 10 monosaccharides. Polysaccharides Polysaccharides are composed of a huge number of monosaccharide units, and the number forming the molecule is often approximately known. For example, cellulose and starch are polysacchar- ides composed of hundreds of glucose units. Classification of monosaccharides according to functional groups and carbon numbers The two most common functional groups found in monosaccharides (in open chain form) are aldehyde and ketone. Sometimes, monosaccharides are classified more precisely to denote the functional group as well as the number of carbon atoms. For example, glucose can be classified as an aldohexose, as it contains six carbon atoms as well as an aldehyde group. If any monosaccharide lacks the usual numbers of hydroxyl groups, it is often called a deoxy sugar. For example, 2-amino-2- deoxy-D-glucose, also known as glucosamine, is an amino sugar, and glucuronic acid is a sugar acid. It can be noted that D- and L-notations have no relation to the direction in which a given sugar rotates the plane-polarized light i. In Fischer projections, most natural sugars have the hydroxyl group at the highest numbered chiral carbon pointing to the right. In Fischer projections, L-sugars have the hydroxyl group at the highest numbered chiral carbon pointing to the left. When a sample of either pure anomer is dissolved in water, its optical rotation slowly changes and ultimately reaches a constant value of þ 52. Both anomers, in solution, reach an equilibrium with fixed amounts of a (35 per cent), b (64 per cent) and open chain ($1 per cent) forms. For example, the anomeric carbon (C-1) in glucose is a hemiacetal, and that in fructose is a hemiketal. Only hemi-acetals and hemiketals can exist in equilibrium with an open chain form. Acetals and ketals do not undergo mutarotation or show any of the reactions specific to the aldehyde or ketone groups. When glucose is treated with methanol containing hydrogen chloride, and prolonged heat is applied, acetals are formed. A sugar solution contains two cyclic anomers and the open chain form in an equilibrium. Once the aldehyde or ketone group of the open chain form is used up in a reaction, the cyclic forms open up to produce more open chain form to maintain the equilibrium. Although only a small amount of the open chain form is present at any given time, that small amount is reduced. Then more is produced by opening of the pyranose form, and that additional amount is reduced, and so on until the entire sample has undergone reaction. Reaction (reduction) with phenylhydrazine (osazone test) The open chain form of the sugar reacts with phenylhydrazine to produce a pheny- losazone. Three moles of phenylhydrazine are used, but only two moles taken up at C-1 and C-2. If we examine the structures of glucose and mannose, the only structural difference we can identify is the orientation of the hydroxyl group at C-2. These reactions are simple chemical tests for reducing sugars (sugars that can reduce an oxidizing agent). Cu2O ðred=brownÞþoxidized sugar Although majority of sugar molecules are in cyclic form, the small amounts of open chain molecules are responsible for this reaction. Therefore, glucose (open chain is an aldose) and fructose (open chain is a ketose) give positive test and are reducing sugars. For example, when glucose is treated with acetic anhydride and pyridine, it forms a pentaacetate. The ester functions in glucopyranose pentaacetate undergo the typical ester reactions.

Break this question into parts and it becomes easier to locate which gland is being referenced: Superior means “upper quality 2.5mg oxybutynin,” media– means “middle” (or “midline”) quality 5mg oxybutynin, and –stinum refers to the ster- num, or breastbone. It recycles critical components from the spent blood cells and sends them to the bone marrow to be turned into fresh cells. A The lymph system offers an alternative route for the return of the tissue fluid to the blood- stream. True B The fluid surrounding the cells that will enter the lymph capillaries is called interstitial fluid. True C Lymph from the lymph vessels flows into the right thoracic duct and the left thoracic duct. False F The thymus gland is functional in the early years of life and is most active in old age. G Tonsils function to protect against pathogens and foreign substances that are inhaled or ingested. True H The spleen functions in the removal of aged and defective blood cells and platelets from the blood. This statement doesn’t make much sense because “gastric” refers to the digestive system. J The thoracic duct originates from a triangular sac called the chyle cistern (or cisterna chyli). M Peyer’s patches are masses of lymphatic nodules found in the distal portion of the small intes- tines. You may be tempted to write “thoracic duct” here, but that’s incorrect because the duct is the largest vessel, not the largest organ. P In the center of the nodules of the lymph node are areas called germinal centers. When you read “germinal,” think of the word “germinate,” and then think of a place where lymphocytes can sprout and mature. Chapter 12 Filtering Out the Junk: The Urinary System In This Chapter Putting the kidneys on clean-up duty Tracking urinary waste out of the body f you read Chapter 9 on the digestive system, you may be chewing on the idea that undi- Igested food is the body’s primary waste product. We make more of it than we do feces — in fact, our bodies are making small amounts of urine all the time — and we release it more often throughout the day. Most important, urine captures all the leftovers from our cells’ metabolic activities and jettisons them before they can build up and become toxic. In addition, urine helps maintain homeostasis, or the proper balance of body fluids. In short, the urinary system Excretes useless and harmful material that it filters from blood plasma, including urea, uric acid, creatinine, and various salts Removes excess materials, particularly anything normally present in the blood that builds up to excessive levels Maintains proper osmotic pressure, or fluid balance, by eliminating excess water when concentration rises too high at the tissue level In this chapter, we look at how the urinary system collects, manages, and excretes the waste that the body’s cells produce as they go about busily metabolizing all day. You practice iden- tifying parts of the kidneys, ureter, urinary bladder, and urethra. Examining the Kidneys, the Body’s Filters The kidneys are nonstop filters that sift through 1. Humans have a pair of kidneys just above the waist (lumbar region) toward the back of the abdominal cavity. While sometimes the same size, the left kidney tends to be a bit larger than the right. The last two pairs of ribs surround and protect each kidney, and a layer of fat, called perirenal fat, pro- vides additional cushioning. Kidneys are retroperitoneal, which means that they’re posterior to the peritoneum. The renal capsule, or outer lining of the kidney, is a layer of collagen fibers; these fibers extend outward to anchor the organ to surrounding structures. Each kidney is dark red, about 4 ⁄12 inches long, and shaped like a bean (hence the type of legumes called kidney beans). The portion of the bean that folds in on itself, referred to as the medial border, is concave with a deep depression in it called the hilus, or hilum. The hilus opens into a fat-filled space called the renal sinus, which in turn contains the renal pelvis, renal calices, blood vessels, nerves, and fat. Immediately below the renal capsule is a granular layer called the renal cortex, and just below that is an inner layer called the medulla that folds into anywhere from 8 to 18 conical projections called the renal pyramids. Between the pyramids are renal columns that extend from the cortex inward to the renal sinus. The tips of these pyramids, the renal papillae, empty their contents into a collecting area called the minor calyx. It’s one of several sac-like structures referred to as the minor and major calyces which form the start of the urinary tract’s “plumbing” system and collect urine transmitted through the papillae from the cortex and medulla. Although the number varies between individuals, generally each of two or three major calyces branches into four or five minor calyces, with a single minor calyx surrounding the papilla of one pyra- mid.

Include client in making decisions related to selection of alternative coping strategies generic 5mg oxybutynin amex. If the client elects to work on elimination of the fear discount oxybutynin 2.5mg overnight delivery, tech- niques of desensitization may be employed. This is a sys- tematic plan of behavior modification, designed to expose the individual gradually to the situation or object (either in reality or through fantasizing) until the fear is no longer experienced. This is also sometimes accomplished through implosion therapy, in which the individual is “flooded” with stimuli related to the phobic situation or object (rather than in gradual steps) until anxiety is no longer experienced in relation to the object or situation. Fear is decreased as the physical and psychological sensations diminish in response to repeated exposure to the phobic stimulus under non- threatening conditions. Encourage client to explore underlying feelings that may be contributing to irrational fears. Help client to understand how facing these feelings, rather than suppressing them, can result in more adaptive coping abilities. Verbalization of feelings in a nonthreatening environment may help client come to terms with unresolved issues. Client does not experience disabling fear when exposed to phobic object or situation, or 2. Client verbalizes ways in which he or she will be able to avoid the phobic object or situation with minimal change in lifestyle. Client is able to demonstrate adaptive coping techniques that may be used to maintain anxiety at a tolerable level. Possible Etiologies (“related to”) [Underdeveloped ego; punitive superego] [Fear of failure] Situational crises Maturational crises [Personal vulnerability] [Inadequate support systems] [Unmet dependency needs] Defining Characteristics (“evidenced by”) [Ritualistic behavior] [Obsessive thoughts] Inability to meet basic needs Inability to meet role expectations Inadequate problem solving [Alteration in societal participation] Goals/Objectives Short-term Goal Within 1 week, client will decrease participation in ritualistic behavior by half. Long-term Goal By time of discharge from treatment, client will demonstrate abil- ity to cope effectively without resorting to obsessive-compulsive behaviors or increased dependency. Try to determine the types of situations that increase anxiety and result in ritualistic behav- iors. Recognition of precipitating factors is the first step in teaching the client to interrupt the escalating anxiety. Encour- age independence and give positive reinforcement for inde- pendent behaviors. Sudden and complete elimination of all avenues for dependency would create intense anxiety on the part of the client. Positive reinforcement enhances self-esteem and encourages repetition of desired behaviors. Client may be unaware of the relationship between emotional problems and compulsive behaviors. Provide structured schedule of activities for the client, includ- ing adequate time for completion of rituals. Gradually begin to limit the amount of time allotted for ritualistic behavior as client becomes more involved in unit activities. Anxiety is minimized when client is able to replace ritualistic behaviors with more adaptive ones. Positive reinforcement enhances self-esteem and encourages repetition of desired behaviors. Encourage recognition of situations that provoke obsessive thoughts or ritualistic behaviors. Client is able to verbalize signs and symptoms of increasing anxiety and intervene to maintain anxiety at manageable level. Client demonstrates ability to interrupt obsessive thoughts and refrain from ritualistic behaviors in response to stressful situations. Possible Etiologies (“related to”) Lifestyle of helplessness [Fear of disapproval from others] [Unmet dependency needs] [Lack of positive feedback] [Consistent negative feedback] Defining Characteristics (“evidenced by”) Verbal expressions of having no control (e. Long-term Goal Client will be able to effectively problem-solve ways to take con- trol of his or her life situation by discharge, thereby decreasing feelings of powerlessness. Allow client to take as much responsibility as possible for own self-care practices. Respect client’s right to make those decisions independently, and refrain from attempting to influence him or her toward those that may seem more logical. Unrealistic goals set the client up for failure and reinforce feelings of powerlessness. Client’s emotional condition interferes with his or her ability to solve problems. Assistance is required to perceive the benefits and consequences of available alternatives accurately. Help client identify areas of life situation that are not with- in his or her ability to control. Encourage verbalization of feelings related to this inability in an effort to deal with unresolved issues and accept what cannot be changed. Encourage par- ticipation in these activities, and provide positive reinforce- ment for participation, as well as for achievement. Client verbalizes choices made in a plan to maintain control over his or her life situation.

Therefore cheap 5mg oxybutynin fast delivery, sexual behaviour also occurs within the context of specific communities with their own sets of norms and values generic oxybutynin 2.5mg free shipping. Many of these discussions about sex challenge the traditional biological reductionist approach to sex and argue for an understanding of sex within a context of social meanings and discourses. These behaviours have been predominantly understood using cognitive models, which emphasize individual differences and individual cognitions. However, sex presents a problem for psychologists as it is intrinsically an interactive behaviour involving more than one person. Therefore, cognitive models have been expanded in an attempt to emphasize cognitions about the individual’s social world, particularly in terms of the relationship. To further the understanding of sex as an interaction, qualitative methods have been used to examine the process of negotiation. Social cognition models have also been developed in an attempt to address individuals’ representations of this world – their normative beliefs. Consider a recent advertisement and discuss whether or not this would encourage you to use condoms. It is believed that questionnaires/interviews provide us with insights into what people think and believe. Do people have behavioural intentions prior to being asked whether they intend to behave in a particular way? Social psycholo- gists have studied processes such as conformity, group dynamics, obedience to authority and diffusion of responsibility, all of which suggest that individuals behave differently when on their own than when in the presence of others and also indicate the extent to which an individual’s behaviour is determined by their context. How- ever, much psychological research continues to examine behaviour and beliefs out of context. It is assumed that eventually we will develop the best way to study sex, which will enable us to understand and predict sexual behaviour. However, perhaps the different approaches to sex can tell us something about the way we see individuals. For example, attempt- ing to incorporate interactions between individuals into an understanding of sex may be a better way of understanding sex, and it may also suggest that we now see individuals as being interactive. In addition, examining the social context may also suggest that our model of individuals is changing and we see individuals as being social products. This paper examines the multitude of information sources used by young people in the context of current school health education. It outlines the guidelines for developing screening programmes and assesses the patient, health professional and organizational predictors of screening uptake. The chapter then examines recent research which has emphasized the negative consequences of screening in terms of ethical principles, the cost effectiveness and the possible psychological consequences. There are three forms of prevention aimed at improving a nation’s health: 1 Primary prevention refers to the modification of risk factors (such as smoking, diet, alcohol intake) before illness onset. The recently developed health promotion campaigns are a form of primary prevention. Screening programmes (secondary prevention) take the form of health checks, such as measuring weight, blood pressure, height (particularly in children), urine, carrying out cervical smears and mammograms and offering genetic tests for illnesses such as Huntington’s disease, some forms of breast cancer and cystic fibrosis. Until recently, two broad types of screening were defined: opportunistic screening, which involves using the time when a patient is involved with the medical services to measure aspects of their health. For example, people are encouraged to practise breast and testicular self-examination and it is now possible to buy over-the-counter kits to measure blood pressure, cholesterol and blood sugar levels. The aim of all screening programmes is to detect a problem at the asymptomatic stage. For example, cervical screening may detect precancer- ous cells which place the individual at risk of cervical cancer, genetic screening for cystic fibrosis would give the person an estimate of risk of producing children with cystic fibrosis and cholesterol screening could place an individual at high risk of developing coronary heart disease. For example, a mammogram may discover breast cancer, genetic testing may discover the gene for Huntington’s disease and blood pressure assessment may discover hypertension. The drive to detect an illness at an asymptomatic stage of its develop- ment (secondary prevention) can be seen throughout both secondary and primary care across the Western world. In Britain, the inter-war years saw the development of the Pioneer Health Centre in Peckham, south London, which provided both a social and health nucleus for the community and enabled the health of the local community to be surveyed and monitored with ease (Williamson and Pearse 1938; Pearse and Crocker 1943). Sweden mounted a large-scale multiphasic screening programme that was completed in 1969 and similar programmes were set up in the former West Germany and Japan in 1970. In London, in 1973, the Medical Centre at King’s Cross organized a computerized automated unit that could screen 15,000 individuals a year. General practice also promoted the use of screening to evaluate what Last (1963) called the ‘iceberg of disease’. In the 1960s and 1970s, primary care developed screening programmes for disorders such as anaemia (Ashworth 1963), diabetes (Redhead 1960), bronchitis (Gregg 1966), cervical cancer (Freeling 1965) and breast cancer (Holleb et al. Recent screening programmes Enthusiasm for screening has continued into recent years. The report (Forrest 1986) concluded that the evidence of the efficacy of screening was sufficient to establish a screening programme with three-year intervals. Furthermore, in the late 1980s, Family Practitioner Committees began computer-assisted calls of patients for cervical screening, and in 1993 a report from the Professional Advisory Committee for the British Diabetic Association suggested implementing a national screening programme for non-insulin-dependent diabetes for individuals aged 40–75 years (Patterson 1993).
