Low concentrations (0.10 to 1.0 microgram/ml) of alpha-amanitin inhibit wheat embryo germination. Labeled RNA, synthesized in vivo by embryos imbibed in the presence of [3H]uridine and various concentrations of alpha-amanitin, was analyzed by oligo(dT)-cellulose chromatograhy and by gel electrophoresis (acrylamide and agarose) coupled with fluorography. Low concentrations of alpha-amanitin (0.1...

A technique for measuring the alkaline phosphatase activity of serum protein fractions separated by electrophoresis on cellulose acetate strips is described. Alkaline phosphatase activity in alpha 2, alpha 1, and beta globulins and in albumin is present in varying proportions in normal and pathological sera. In normal sera peak activity is in the alpha 2 globulins and beta globulins have a litt...

losartan potassium is a well known orally active non-peptide angiotensin ii receptor antagonist. losartan potassium and its principle active metabolites block the vasoconstrictor and aldosterone secreting effect of angiotensin ii by selectively blocking the binding of angiotensin ii to at1 receptors. the drug is reported to promote the decrease in ventricular hypertrophy, salt and water excreti...

Lyotropic liquid crystals based on mixtures of cellulose tricarbanilates (urethanes) generated stronger selective reflection in the visible range after an increase in concentration of approximately 9 wt.-% above the concentrations described by Miiller, Zentel, and Keller in "Solid Opalescent Films Originating from Urethanes of Cellulose".[2] The cellulose urethanes used were of a lower molecula...

We test the hypothesis that the estrogen metabolite ratio 2-OH-estrone:estriol can be raised via dietary indole-3-carbinol (I3C) and that this higher ratio can be sustained over a 3-month test period. We also explore the possible role of pure fiber on estradiol metabolism. Using a randomized clinical trial with three arms, each containing 20 subjects, arm 1 received 400 mg/day of I3C daily for ...

In this study, microcrystalline cellulose (MCC) was isolated from walnut and apricot shells (WS AS) as agricultural wastes in order to use it reinforcement polymer composites. The extracted by alkaline treatment bleached peroxide an environmentally friendly treatment, called (WC) (AC). chemical composition of the samples set according Technical Association Pulp Paper Industry (TAPP). After trea...

The aim of the study was to investigate the physical stability of the semi-solid dispersions into the hard gelatine capsules prepared with Gelucire 44/14, Labrasol and different additives such as microcrystalline cellulose (MCC), mannitol and lactose (alpha-monohydrate) used for enhancing the stability of the formulations. The master dispersion prepared with only Gelucire 44/14 (20% w/w) and La...
