What is Sildenafil

Mechanism of action Sildenafil citrate mechanism of action involves the release of nitric oxide (NO) in the corpus cavernosum of the penis. NO binds to the receptors of the enzyme guanylate cyclase, which results in increased levels of cyclic guanosine monophosphate (cGMP), which muscle relaxation (vasodilatation) for smoothing the cushions of the intima of arteries helicinae, resulting increased blood flow and an erection.
Sildenafil is a potent and selective inhibitor of cGMP specific phosphodiesterase type 5 (PDE5) which is responsible for degradation of cGMP in the corpus cavernosum. The molecular structure of sildenafil is similar to that of cGMP and functions as a competitive binding agent of PDE5 in the corpus cavernosum, resulting in more cGMP and better erection. Without sexual stimulation, and therefore lack of activation of the NO / cGMP system, sildenafil should not cause an erection. Other drugs that, by the same mechanism tadalafil (Cialis) and vardenafil (Levitra) are operated.
Sildenafil is metabolised by liver enzymes and excreted by the liver and kidneys. Absorption When taken with a high fat meal reduced; time to maximum plasma concentration is increased by about an hour, and the maximum concentration itself is reduced to obtain about a third.

use:
1) Sexual dysfunction
The primary indication of sildenafil is treatment of erectile dysfunction (inability to fulfill to get a satisfactory erection traffic). It is now using the standard treatment for erectile dysfunction in all settings, including diabetes.
People on antidepressants may occur either sexual dysfunction because of their illness or as a result of their treatment. A 2003 study showed that sildenafil improved

sexual function in men in this situation. Up previous reports of 1999, found the same researchers found that sildenafil was able and sexual function in women, improve anti-depressants.
2) Pulmonary hypertension
In addition to erectile dysfunction, sildenafil citrate is also effective in the rare disease pulmonary arterial hypertension (PAH). It relaxes the artery wall, which reduces pulmonary arterial resistance and pressure. This reduces the workload of the right ventricle of the heart and improves symptoms of right heart failure. Because PDE-5 is primarily distributed within the arterial wall smooth muscle lung and penis, sildenafil acts selectively in both areas without vasodilation in other areas of the body to induce.
3) altitude
Sildenafil is for the prevention and treatment of pulmonary edema associated with altitude high altitude sickness, as they proved suffered by mountaineers to be useful. Although this effect was only recently discovered, sildenafil is already becoming an accepted treatment for this condition, especially in situations where delays the standard treatment of rapid descent for any reason.
4) Use in Sports
Professional sports players have been using drugs. It can open their blood vessels will enrich their muscles, increasing their effectiveness.

How to buy T84

Berberine is a plant alkaloid with multiple pharmacological effects, including anti-diarrheal activity, and secretion is Cl in the distal colon to inhibit shown. The objectives of this study were to determine the molecular signaling mechanisms of berberine on secretion and ion transporters Cl goals. culture monolayers of human T84 bearing permeable colon carcinoma cells were placed in Ussing chambers and measured short-circuit current in response to secretagogues and berberine. current records of whole cells were carried out in T84 cells using the patch clamp. Berberine reduces the short-circuit current induced by forskolin in a manner dependent on the concentration (IC 50 80 ± 8 pM). In monolayers permeabilized apically and current records of whole cells, berberine inhibited cAMP-dependent and chromanol 293B sensitive basolateral membrane K + current by 88%, suggesting inhibition of KCNQ1 K + channels. Berberine did not affect apical or basolateral conductance Cl + -K + -ATPase Na. Berberine stimulates p38 MAPK and PKA PKC, but had no effect on p42 / p44 MAPK and PKCô. However berberine pretreatment prevented the stimulation of p42 / p44 MAPK by epidermal growth factor. The inhibitory effect of berberine on Cl- secretion was partially offset by HBDDE (~ 65%), an inhibitor of PKC and blocked to a lesser extent by the inhibition of p38 by SB202190 (~ 15%) . treatment with berberine increased association between PKC and PKA with KCNQ1 and produces the induced phosphorylation of channels. We conclude that berberine on Cl secretion by inhibiting colon channels KCNQ1 basolateral exerts its inhibitory action responsible for the K + recycling a PKC-dependent pathway.

How to use Vardenafil

Vardenafil is a tablet and a rapidly disintegrating (dissolves in the mouth and swallowed without water) to take the tablet in the mouth. It is generally considered necessary, with or without food 60 minutes before sexual activity. Vardenafil should not be taken as once every 24 hours usually frequent. If you have health problems or are taking certain medications, your doctor may tell you to take vardenafil less often. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take vardenafil exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor take.

If you quickly disintegrating tablet, see the blister before your first dose. Do not use the medication package when the bubbles are broken, cracked, or do not contain tablets. Follow the instructions on the package to remove the tablet from the blister. Do not try to push the tablet through the foil. After removing the tablet from the blister, they put immediately on the tongue and close the mouth. The tablet will dissolve rapidly. Do not take the rapid dissolution with water or other liquids tablets.

Your doctor will probably start at a mean dose of vardenafil tablets and increase or decrease depending on the response to the drug. Dose If you take the fast disintegrating tablets, your doctor will not be able to adjust your dose, because the tablets are available in a rapidly disintegrating available thickness. If you need a higher or lower dose, your doctor may prescribe regular tablets instead. Tell your doctor if vardenafil is not working well or if you experience side effects.

Vardenafil rapidly disintegrating tablets can not be replaced vardenafil tablets. Make sure you get only the kind of vardenafil, which was prescribed by your doctor. Have you given your pharmacist if you have questions about the type of vardenafil.

What is Ghrelin

Ghrelin is the endogenous ligand for the receptor of the growth hormone secretagogue (GHS-R) present on the pituitary cells secrete growth hormone. Ghrelin and motilin and GHS-R and the motilin receptor are structurally related. Ghrelin, surprisingly, is the most abundant in the stomach and the GHS-R is also in the stomach and other organs and tissues, effects on the stimulation of growth hormone from the pituitary gland which suggests, particularly in the regulation of gastrointestinal function. But still seems rather a ghrelin through the digestive system works differently signal that regulates digestion. The most important role of ghrelin seems to stimulate appetite and regulate energy homeostasis, favoring adiposity and contribute to obesity. As recently suggested, ghrelin may therefore "saginary" (fattening) peptide called. Ghrelin can affect the secretion of gastric acid and gastric protection, but the proposed role of ghrelin in infection by Helicobacter pylori, in turn involves saginary effect. Ghrelin is functionally related to the motilin because it also stimulates gastrointestinal motility. In rodents taken motilin function have ghrelin, such as motilin natural knockouts are rodents. Ghrelin appears as an endocrine signal can reach the central nervous system via the blood stream. However, he also used neural pathways, particularly the vagus. A better understanding of the physiology of ghrelin may lead to new therapies for the treatment of obesity and hypomotility syndromes.

Leptin for sale

Diabetes is one of the biggest problem in the world. Despite some progress in the development of new anti-diabetic agents, the ability to maintain tight glycemic control to prevent kidney, retina and neuropathic complications of diabetes without adverse complications remains a challenge. However, recent results suggest that in addition to playing a key role in regulating energy homeostasis of the hormone leptin adiposity plays an important role in the control of glucose metabolism through its actions in the brain. This review focuses on the role of leptin action in the central nervous system and the mechanisms by leptin mediates its effects to regulate glucose metabolism. These results suggest that defects or defects in the leptin signaling may contribute to the etiology of diabetes and raise the possibility that either leptin or downstream targets of leptin may have therapeutic potential for the treatment of diabetes.

Mass spectrometry and chromatography, the main metabolite (about 70%) is a bile acid monoketo dihydroxybenzyl (cholanic acid 3α, 7α-dihydroxy-12-keto-5β); a second metabolite (approximately 20%) is a monohydroxy-diketo acid (cholanic 3α-hydroxy-7,12-di-keto-5β); and about 10% of the radioactivity was as cholic acid. The reduction appears to have been sequentially (3 positions, the positions 7 and 12 position) and stereospecific (only α epimer was recovered).
Bile, as the ratio between the flow of bile acid excretion in the bile expressed was increased by dehydrocholic administration. It was hypothesized that ketone hydroxylated metabolites are hydrocholeretics. not significantly change after the administration of the proportion of cholesterol into bile acids, lecithin and dehydrocholic. In vitro studies have shown that keto-hydroxy metabolites cholate are dispersed lecithin bad compared; However, mixtures of cholate and either a dispersion metabolite has similar properties to those alone, provided that the ratio of cholate metabolites for each metabolite remained cholate below a characteristic value. The experiments reveal a new metabolic pathway in humans, provide further insight into the hydrocholeresis induced keto bile acids, and show the remarkable change of pharmacological and physical properties. Replacement of hydroxyl group by a keto substituent in the bile acid molecule

Muscle glycogen concept

The importance of carbohydrates as an energy source during endurance training is known for 60 years. With the advent of needle muscle biopsy in the 1960s, it was found that the main source of carbohydrates during exercise are the glycogen reserves. It was shown that the capacity between 65 to 75% VO2max exercised at intensities of pre-exercise glycogen levels in the muscle bound, ie more glycogen reserves, more exercise time to exhaustion. Because of the critical importance of muscle glycogen during prolonged, intense exercise, a considerable amount of research has been conducted in order to design the best diet to increase muscle glycogen stores prior to the competition and the most effective means of replenishment quickly determining the glycogen after training. The rate determining step in the glycogen synthesis is the transfer of glucose from uridine diphosphate-glucose on an amylose chain. This reaction is catalyzed by the enzyme glycogen synthase, which in a glucose 6-phosphate-dependent, inactive form (form D) and an active form of glucose 6-phosphate can independent (I-form) exist. The conversion of glycogen synthase from one form to the other is controlled by phosphorylation-dephosphorylation reactions. The concentration of muscle glycogen can vary greatly depending on the level of conditioning, exercise routines and diet. The pattern of muscle glycogen re-synthesis after exercise-induced exhaustion is biphasic. After completion of movement and adequate glycogen muscle carbohydrate consumption is rapidly resynthesized to close before training levels within 24 hours. Muscle glycogen then increased very gradually to normal in the coming days. A contribution to the rapid phase of the re-synthesis is to increase the proportion of glycogen synthase I, an increase in muscle cell membrane permeability to glucose and an increased sensitivity of muscle to insulin. The slow phase of the glycogen synthesis is under the control of the intermediate form of glycogen synthase, which is very sensitive to the activation of the glucose 6-phosphate. The conversion of the enzyme can be attributed to this intermediate to form a plasma insulin concentration elevated after several days of high consumption of carbohydrates constantly exposed to muscle tissue. For optimal performance of the exercise, muscle glycogen stores must be replenished on a daily basis again. For athletes daily average endurance of a carbohydrate consumption of 500 to 600 g is required. This leads to a maximum glycogen from 80 to 100 micromol / g wet weight.

Thebaine content and Plant

Four varieties of thebaine-rich P. bracteatum grown outdoors on two seasons and distribution of thebaine in the aerial parts considered the most suitable raw material for commercial production to be determined. The leaves contain only 0-1 to 0-15%; capsules 0-5 to 3-0% and 28-53% latex bled. The maximum for the latter occurred about 3-4 weeks after the opening of the petals and during the day, at about 15.00 pm. A product 'bractium' just prepared as opium of P. somniferum contain up to 55% thebaine and calculations of the 1974 results provided theoretical yields of up to 58 k of thebaine per hectare. However, this method is very labor; more latex bled represents only 46% of the total thebaine of the capsule. Also contain significant amounts of thebaine stalks so that the seed heads can be recommended as a starting material. In the capsule of thebaine content peaked at 3 to 4 weeks after the opening of the petals and again two weeks later. At this stage, mature, there is a theoretical yield of 50 kg per hectare. Two other advantages result from the collection at that time mature seeds can probably be used for similar purposes in a poppy; and fruit walls at this stage does not contain thebaine bound '(i, e, thebaine insoluble in MeOH but soluble in acetic acid; NH4OH - linked in immature capsules thebaine 18-36% of the total thebaine represents. ). There is some evidence that, as these perennial increases in age, the ability of thebaine increase seems to continue production. Storage of the raw material, even under ideal conditions, resulting in a loss of thebaine between 12 and 20% in one year.
