This metabolic pathway in addition to erectile dysfunction treatment in lahore buy viagra sublingual in united states online providing energy provides building blocks required for growth impotence psychological treatment buy viagra sublingual without a prescription, reproduction laptop causes erectile dysfunction order genuine viagra sublingual, repair and maintenance of cellular viability. Structurally it is bounded by two separate membranes (outer mitochondrial membrane and inner mitochondrial membrane) Out membrane - smooth and unfolded - Freely permeable to most ions and polar molecules (Contain porous channels) Inner membrane - folded into cristae-increased surface area - Highly impermeable to most ions and polar molecules Contain transporters which access polar and ionic molecules in and out Cristae are characteristic of muscle and other metabolically active cell types - Protein-rich membrane (about 75%) Inter membrane space space between outer and inner membranes Matrix-the internal compartment containing soluble enzymes and mitochondrial genetic material Fig 3. Inside matrix pyruvate is oxidized into acetylCoA by pyruvate dehydrogenase complex which is complex of E1, E2 and E3 enzymes. Reactions take place in cytosol of prokaryotes and mitochondria matrix of eukaryotes 63 Fig 3. Considerable free energy is lost as heat due to hydrolysis of thisester bond (drive the reaction forward). This enzyme has the same coenzyme requirement to that of pyruvate dehydrogenase complex. Transfer and accept two electrons at a time Cytochromes heme conjugated proteins Heme = Fe2+/F3+ + porphyrin Include classes of cytochromes designated a, b, and c. Iron at the center of cytochromes accept and donates single electron Cytochrone Fe2+ (reduced) Cytochrome Fe3+ + e(Oxidized) Cytochrome with relatively less positive reduction potential. CoQ and cytochrome C are mobile electron carriers which act as a link between the complexes. The free energy released is captured at three sites to pump protons against concentration gradient from matrix to inter membrane space generating proton gradient across inner mitochondrial membrane. As a result of this pH gradient is also formed, more positive (acidic) on the outer side more negative (basic) on the inner side of mitochondria. Now the kinetic energy of electrons is transformed into the proton motive force. They also dissolve the vitamins, which are fat-soluble and assist their digestion. Complex lipids:- Esters of fatty acids and alcohols together with some other head groups. Glycerophospholipids:- the alcohol is glycerol Sphingophospholipids:- the alcohol is shingosine. Glycolipids:- Lipids containing fatty acid, sphingosine and carbohydrate residues. Others:- Include sulfolipids, amino lipids and lipoproteins, which are modified forms of lipids. The simplest naturally occurring lipids are triacylglycerols formed by esterification of fatty acids with glycerol. Mostly the double bond occurs at the 9th carbon as we count from the carboxyl group end. In a different way the position of the double bond(s) can be indicated as shown in the second expression without the delta. C18:1, 9 or 18:1(9) C18 indicates 18 carbons, 1 indicates the number of double bonds, delta 9(9) indicates the position of double bond between 9th and 10th carbon atoms. Double bonds in naturally occuring fatty acids are in the cis- configuration and saturated fatty acids of C12 to C24 are solids at body temperature but the unsaturated once are liquids. Poly unsaturated fatty acids are released from membranes, diverted for the synthesis of prostaglandins, leukotriens and thromboxanes. They act as fat mobilizing agents in liver and protect liver from accumulating fats (fatty liver). Triacylglycerols or also called as triacylglycerides, exist as simple or mixed types depending on the type of fatty acids that form esters with the glycerol. Both saturated and/or unsaturated fatty acids can form the ester linkage with the backbone alcohol. Triacylglycerols are mainly found in special cells called adipocytes (fat cells), of the mamary gland, abdomen and under skin of animals. Structure of phosphatidate Phosphatidate is the parent compound for the formation of the different glycerophospholipids.

Pharmacotherapy of Allergic Diseases Carlos E Baena-Cagnani, Hйctor Badellino Key statements · · · Subjects from all countries, ethnic and socio-economic groups and ages suffer from allergies. Asthma and allergic rhinitis are common health problems that cause major illnesses and disability worldwide. The burden of allergic diseases is huge at both an individual and a familial level. This translates to an increased burden at a national level, making allergies a public health issue. Allergic diseases are complex because both genetic and environmental factors influence disease development. They show a strong familial and intra-individual clustering, suggesting overlapping disease aetiology. It is clear that the recent increase in the prevalence of allergic rhinitis and asthma cannot be due to a change in the gene pool. Allergic rhinitis is a major chronic respiratory disease due to its prevalence, impact on quality of life, work/school performance, economic burden and links with asthma and other co-morbidities. Allergic rhinitis is part of the ``allergic march' during childhood, but intermittent allergic rhinitis is unusual before two years of age and is most prevalent during school age years. Interactions between the lower and the upper airways are well known and have been extensively studied since 1990. Over 80% of asthmatics have rhinitis, and 10-40% of patients with rhinitis have asthma. Most patients with asthma have rhinitis, suggesting the concept of "one airway, one disease", although there are underlying differences between rhinitis and asthma. The socio-economic consequence and impact of allergies is often underestimated and allergic diseases are frequently undertreated, causing substantially elevated direct and indirect costs. Symptom control, improvement in quality of life and rehabilitation to normal (or almost normal) function can be achieved through modern pharmacological treatment. Disease management that follows evidence-based practice guidelines yields better patient results, but such guidelines may recommend the use of resources not available in the family practice setting. Goals for the treatment of rhinitis include unimpaired sleep, ability to perform normal daily activities (including work/school attendance), and sport/leisure activities, with no or minimal sideeffects of drugs. The goal of asthma treatment is to achieve and maintain clinical control of symptoms and normal (or near to normal) lung function. This clinical control includes an absence of daytime symptoms, with no limitations of activities including exercise, no nocturnal symptoms, normal or near-normal lung function, and no (or minimal) exacerbations. The following section lists the most commonly used medications for allergic diseases: H1-antihistamines: H1-blockers or H1-antihistamines are shown to be safe and effective in young children. Cetirizine, when compared with placebo, delayed or, in some cases, prevented, the development of asthma in a sub-group of infants with atopic eczema who were sensitized to grass pollen and, to a lesser extent, house dust mite.
Haptoglobulin: It combines with haemoglobin in order to impotence nerve cheap viagra sublingual 100 mg otc remove it from the circulation erectile dysfunction lipitor 100 mg viagra sublingual visa. Ceruloplasmin: A copper binding plasma protein and function as ferrooxidase and converts Fe2+ Fe3+ Erythropoietin: It is involved in erythropoiesis erectile dysfunction evaluation discount viagra sublingual 100 mg free shipping. Other globulins present in plasma are: Fibrinogen: It is similar to globulins because it is precipitated by half saturation with ammonium sulfate. Though it is a globulin by nature it is named as prealbumin because it migrates ahead of a albumin in electrophoresis. Other blood clotting factors, plasminogen and several non-functional enzymes are also present in plasma. They are 1-antitrypsin, haptoglobin, ceruloplasmin, complement-3, fibrinogen and c-reactive protein. Their concentration increases in conditions like surgery, myocardial infraction, infections and tumours. The synthesis of these proteins by liver is triggered by interleukin at the site of injury. C-reactive protein is so called because it forms precipitate with somatic C-polysaccharide of pneumococcus bacteria. Invasion of body by virus or microorganisms or foreign molecules is called infection. They are produced by Proteins 43 B-lymphocytes, bone marrow and spleen in response to infection. Entry of foreign molecule into body triggers the synthesis of specific globulin, which selectively combines with foreign molecule and lead to its inactivation. The foreign molecule is called as antigen where as globulin produced against it is called as antibody. Even without infection the normal plasma contains hundreds of different antibody molecules. Classification the immunoglobulin (Ig) proteins of plasma are divided into three major classes Ig G, Ig A, Ig M and two minor classes Ig D, Ig E based on their composition. Structure the composition and shape of various classes of immunoglobulins have similar pattern and are represented by the structure of major G class of molecule i. Each Ig G molecule consist of 4 polypeptide chains and molecular weight is 150,000. They are two heavy chains or H chains or about 450 amino acids (molecular weight 50,000) and two light or L chains or about 220 amino acids (molecular weight 25,000). Two heavy chains intertwine to form the base of the Y, a disulfide bond links the L chain to H chain to form arm of the Y. The two heavy chains are held together by disulfide bonds formed between them at the hinge region of the Y. The amino acid sequence in the variable regions of H and L chains varies and are specific to the type of antibody. In contrast amino acid sequence in constant region of H and L chains are same in each class of immunoglobulins. The remaining part of the immunoglobulin is called as Fc (fragment with constant domain). The different classes of immunoglobulins vary in their size, distribution, function and composition. It is the only class of antibody that is capable of crossing the placental barrier from the maternal to fetal circulation. Ig G antibodies bind to phagocytic cells thus making a link between antibody and phagocytes. Further, binding of Ig G to foreign cells increases their susceptibility to killer cell attack. It is the chief antibody present in mucous secretions of lungs and gastrointestinal tract.

Toxicity If mega doses of iron is taken excess iron is deposited in liver as hemosiderin impotence age 40 order viagra sublingual 100 mg amex. When the condition is accompanied by bronze pigmentation of skin the condition is called as hemochromatosis erectile dysfunction patanjali medicine discount 100mg viagra sublingual fast delivery. Other hemosiderosis causing conditions are repeated blood transfusions impotence liver disease proven 100mg viagra sublingual, idiopathic hemochromatosis in which iron is absorbed in excess due to inherited defect in regulation of iron absorption and alcoholic cirrhosis. Treatment Iron chelators like desferyioxamine is useful in removing excess iron from the body. It removes iron from the body by forming water soluble complex which is excreted in urine. Sources Cereals, legumes, green leafy vegetables like mint leaves, coriander leaves, spinach and jaggery are good sources. Organ meats like liver, kidney, spleen and farm products like eggs and fish are fair sources. Among different organs of the body prostate (86 mg/100 gm) and choroid of eye are rich in this metal. Absorption and transport Zinc is absorbed by carrier mediated process in duodenum and jejunum. It is required for the activity of enzymes involved in carbohydrate metabolism, protein and amino acid metabolism, nucleic acid metabolism, bone metabolism, blood pressure, gas transport and removal of superoxides. In most of the enzymes zinc is an integral part and it is attached to protein through coordinate covalent bonds. It is a constituent of zinc finger proteins which are involved in regulation of gene expression. It is required for the synthesis of gustin a salivary protein involved in development of taste buds. Zinc deficiency in man has been reported in middle east countries particularly in Egyptian and Iranian dwarfs. In experimental subjects zinc deficiency causes dermatitis, sore throat, immune defects. Toxicity Though it is less common intake of foods, beverages and milk prepared in galvanized vessels leads to zinc poisoning. Absorption Copper absorption in small intestine probably involves two transport processes. High copper in diet induces metallothionin production by mucosal cells which binds copper and inhibits its absorption. Copper is required for the activity of enzymes involved in respiratory chain, cross linking of collagen and elastin, blood cell formation, melanin formation, superoxides removal, neurotransmitter formation and neuropeptides. Some cuproenzymes are cytochrome oxidase, lysyloxidase, superoxide dismutase, ceruloplasmin, tyrosinase, dopamine -oxidase, amine oxidase and uricase. Symptoms are hypochromic anaemia, leukopenia, central nervous system lesions, bone demineralization, demyelination of nerves, fragility of large blood vessels, depigmentation of skin and steely hair. It is rare inherited deficiency disease in which intracellular copper metabolism is defective. It is rare inherited disease in which excess copper is present in tissues due to abnormal metabolism of copper in liver. Clinical symptoms are acute or chronic liver failure, emotional disturbances and dementia. In the eye copper deposit produce golden brown green ring (Kayser-Fleisher ring) in the cornea. It is a fatal diesase and death occurs within few years after the appearance of clinical signs. Treatment Copper chelator like pencilamine is effective in removing excess copper. Remaining is present in muscle, skin, bone, nervous system and other endocrine glands.
