 Stannous Chloride Uses Alerter l'administrateur Recommander à un ami Lien de l'article 

  A solution of Stannous Chloride containing a little hydrochloric acid is used for the tin-plating of steel, in order to make tin cans. An electric potential is applied, and tin metal is formed at the cathode via electrolysis.

  Stannous Chloride www.metal-material.net/Chemical-Products/Stannous-Chloride/ is used as a mordant in textile dyeing because it gives brighter colours with some dyes e.g. cochineal. This mordant has also been used alone to increase the weight of silk.It also finds a use as a catalyst between acetone and hydrogen peroxide to form the tetrameric form of acetone peroxide.

  A related reduction was traditionally used as an analytical test for Hg2+(aq). For example, if SnCl2 is added dropwise into a solution of mercury(II) chloride, a white precipitate of mercury(I) chloride is first formed; as more SnCl2 is added this turns black as metallic mercury is formed. Stannous chloride can be used to test for the presence of gold compounds. SnCl2 turns bright purple in the presence of gold.

 Dynorphin A(1-13) Acetate In Vitro Alerter l'administrateur Recommander à un ami Lien de l'article 

  Dynorphin A is an endogenous opioid peptide that preferentially activates κ opioid receptors and is antinociceptive at physiological concentrations. Levels of dynorphin A and a major metabolite, Dynorphin A(1-13) Acetate increase significantly following spinal cord trauma and reportedly contribute to neurodegeneration associated with secondary injury. Interestingly, both κ opioid and N-methyl-D-aspartate (NMDA) receptor antagonists can modulate dynorphin toxicity, suggesting that dynorphin is acting (directly or indirectly) through κ opioid and/or NMDA receptor (NMDAR) types.   Despite these findings, few studies have systematically explored dynorphin toxicity at the cellular level in defined populations of neurons co-expressing κ opioid and NMDA receptors. To address this question, we isolated populations of neurons enriched in both κ opioid and NMDA receptors from embryonic mouse spinal cord and examined the effects of Dynorphin A(1-13) Acetate on intracellular calcium concentration ([Ca2+]i) and neuronal survival in vitro.   Time-lapse photography was used to repeatedly follow the same neurons before and during experimental treatments. At micromolar concentrations, Dynorphin A(1-13) Acetate www.poly-peptides.com/Polypeptide/Dynorphin-A(1-13)-Acetate/elevated [Ca2+]i and caused a significant loss of neurons.

 Effects of Liquorice extract Alerter l'administrateur Recommander à un ami Lien de l'article 

  Licorice is an herb that is also known by the scientific name, Glycyrrhiza glabra. According to the University of Maryland Medical Center (UMMC), it has been used for centuries in both Eastern and Western medical practices to treat numerous ailments, from respiratory problems to stomach problems.

  Liquorice extract is a concentrated product of the licorice plant, available in liquid or powdered root form. While licorice can have medicinal benefits, it can also produce negative side effects that you, as a potential Liquorice extract user, should be aware of.

  One of the effects of Liquorice extract www.cosmetics-add.com/Herb-Extracts/Liquorice-extract/ can be high blood pressure. A study published in the March–April 2000 edition of the "American Journal of Nephrology" reports that licorice, even in small doses, can cause hypertensive encephalopathy, which is high blood pressure accompanied by nausea, vomiting, dizziness, visual problems and headache.

 Effect of obestatin on normal, diabetic, and adipose macho albino rats Alerter l'administrateur Recommander à un ami Lien de l'article 

  A absolute of 60 macho albino rats were disconnected into six groups: accumulation 1 was the accustomed ascendancy group; accumulation 2, the obestatin-treated group, was injected with 100 μg/kg of obestatin subcutaneously alert circadian for 1 week; accumulation 3 was the diabetic ascendancy group; accumulation 4, the obestatin-treated diabetic group, was injected with obestatin as in accumulation 2; accumulation 5 was the adipose ascendancy group; and accumulation 6, the obestatin-treated adipose group, was injected with obestatin as in accumulation 2. At the end of the beginning period, serum samples were calm afterwards beheading for admiration of abnegation glucose, insulin, triglyceride (TG), and absolute cholesterol. BMI was aswell measured.

  After 1 anniversary of obestatin treatment, the obestatin-treated ascendancy accumulation showed bush changes in serum abnegation glucose, insulin, TG, and absolute cholesterol levels with the barring of BMI, which showed a cogent abatement as compared with the accustomed ascendancy group. However, the obestatin-treated diabetic accumulation showed a cogent abatement in serum abnegation glucose, TG, and absolute cholesterol levels, with a cogent access in insulin level, but an bush change in BMI as compared with the diabetic ascendancy group. In contrast, the obestatin-treated adipose accumulation showed bush changes in serum abnegation glucose and insulin, but cogent abatement in serum TG, absolute cholesterol levels, and BMI as compared with the adipose ascendancy group.

  From these results, we achieve that there is a cogent role for obestatin www.chemicalreagent.net/Products/Obestatin/ in the adjustment of carbohydrate and lipid metabolism, apparent from its aftereffect on glucose, insulin, and serum lipids. Thus, obestatin administering develops new and added able ameliorative approaches to amusement diabetes and obesity.

 Pharmacokinetics and metabolism of formestane in breast cancer patients Alerter l'administrateur Recommander à un ami Lien de l'article 

  Formestane is a steroidal aromatase inhibitor used for treatment of advanced breast cancer. Clinically, it is administered as a depot form once fortnightly by intramuscular (i.m.) injection. To investigate the pharmacokinetics, bioavailability and metabolism of the drug, seven patients received single 250 mg i.m. doses of commercial formestane on Days 0, 21, 35, 49 and 63 of this trial.

  On Day 63, three of the patients received an additional single intravenous (i.v.) pulse dose of 1 mg of 14C-labelled formestane. The plasma kinetics after i.m. dosing confirmed a sustained release of formestane from the site of injection. Within 24–48 h of the first dose, the circulating drug reached a Cmax of 48.0±20.9 nmol/l (mean±S.D.; N=7). At the end of the dosing interval, after 14 days, the plasma concentration was still at 2.3±1.8 nmol/l.

  The kinetic variables did not significantly change during prolonged treatment. Intramuscular doses appear to be fully bioavailable. Following i.v. injection of 14C-formestane www.hormone-pro.com/Male-Sexual-Enhancement/Formestane_4d725d7b/, the unchanged drug disappeared rapidly from plasma, the terminal elimination half-life being 18±2 min (N=3). Plasma clearance, CL was 4.2±1.3 l/(h kg) and the terminal distribution volume Vz was 1.8±0.5 l/kg.
