sulfuric acid ([3-(3-silicapropyl)sulfanyl]propyl]ester (saspspe) is employed as a recyclable catalyst for the silylation of hydroxyl groups. a good range of primary, secondary alcohols and phenolic hydroxyl groups were effectively converted into their corresponding trimethylsilyl ethers with hexamethyldisilazane in the presence of catalytic amounts of saspspe at room temperature with short rea...

conclusions this report is the first to document other treatment possibilities for pressure ulcer and/or stasis dermatitis in cases where the use of topical applied ointments and medications is difficult. this new therapy may therefore help physicians to treat pressure ulcers and stasis dermatitis. case presentation case 1: a 21-year-old japanese female with lower-body paralysis. pressure ulcer...

a growing number of observational and epidemiological studies have suggested that mental illness, in particular mood disorders, is associated with decreased dietary intake and/or cellular abundance of omega-3 polyunsaturated fatty acids (pufa). this has prompted researchers to test the efficacy of omega-3 pufa in a range of different psychiatric disorders. we have critically reviewed the double...

objective: type 2 diabetes mellitus (dm-2) is a chronic and progressive metabolic disorder known as a serious threatening condition in the individual and society. type 2 diabetes mellitus is known as the major cause of cardiovascular diseases (cvd). contradictory evidences about the effect of omega-3 fatty acids on cvd risk factors, particularly hypertension. the aim of this study was to determ...

tranexamic acid is generally used in the treatment of disorders that predispose one to bleeding. it is a synthetic lysine analog that has strong antifibrinolytic activity. plasminogen binds to fibrin to form plasmin, which in turn degrades fibrin into fibrin degradation products. tranexamic acid blocks the lysine binding site on plasminogen and prevents interaction with fibrin. tranexamic acid ...

the mechanism by which bi-and trivalent cations affect human liver phosphatidatephosphohydrolase (pap) activity was investigated. bivalent cations up to 1 mm increased pap activity whereas at higher concentrations the activity of the enzyme decreased. the stimulatory concentration for trivalent cations such as al3+ and cr3+, however, was much lower being 2 m m and 1 m m, respectively. all catio...

background and purpose: the relationship between uric acid and stroke recurrence is ambiguous. some studies have explored this relationship in acute ischemic stroke but had different results. we evaluated the association of admission uric acid level with risk of stroke recurrence in patients with ischemic stroke. methods: we studied ischemic stroke patients presenting to our hospital with magne...

sugarcane bagasse contains cellulose, lignin and hemicellulose, 39-42%, 20-25% and 25-27% respectively. so it is can be used as a sugar source in many processes. lignin and hemicellulose must be removed before hydrolysis of cellulose. several different pretreatment approaches have been studied. the purpose of this research is comparison of acid, ozone and combination of ozone-acid as pretreatme...

we have investigated the preventive effects of oral administration of isolated e.coli ghttam'tc acid decarboxylase (gad) in animal models. based on our results, the blood glucose levels were reduced by oral administration of gad to rats 14 days before intraperitoneal injections of streptozocin (40 mg/kg on five consecutive days). on the other hand, oral administration of gad to rats before stre...
