BACKGROUND The description of new hydrolytic enzymes is an important step in the development of techniques which use lignocellulosic materials as a starting point for fuel production. Sugarcane bagasse, which is subjected to pre-treatment, hydrolysis and fermentation for the production of ethanol in several test refineries, is the most promising source of raw material for the production of seco...

Sodium carboxymethylcellulose (SCMC) has been effective in reducing adhesion formation and corticosteroids reduce the inflammatory process. The objective of this study was to define the intraperitoneal (ip) effects of SCMC combined with intramuscular (im) methylprednisolone on peritoneal adhesion formation and on jejunal anastomosis healing in rats. Twenty Wistar rats (200-350 g) were divided i...

Synthesis of collagen types I, II, III, and IV in cells from the embryonic chick cornea was studied using specific antibodies and immunofluorescence. Synthesis of radioactively labeled collagen types I and III was followed by fluorographic detection of cyanogen bromide peptides on polyacrylamide slab gels and by carboxymethylcellulose chromatography followed by disc gel electrophoresis. Type II...

Nuclear proteins modified by mono or poly ADP-ribosylation were selectively isolated and purified by covalent chromatography on a dihydroxyboryl polyacrylamide bead column that specifically interacts with cis-diol-containing compounds. From rat liver nuclei that had been incubated with NAD+, histones and some nonhistone proteins were extracted with 0.25 M HCl. Approximately 60% of the ADP-ribos...

trans-Resveratrol was reported to have health benefits including anticarcinogenic effects and protection against cardiovascular disease. One of the mechanisms by which it exerts its action is through modulating the estrogen response systems. Because estrogen is involved in male reproductive biology, we investigated the effect of trans-resveratrol on testis and spermatogenesis. Adult male rats w...

BACKGROUND/AIMS Contact tonometry is generally considered more accurate than non-contact tonometry in the assessment of intraocular pressure (IOP). This study was designed to investigate the effect of ocular anesthesia, a pre-requisite for contact tonometry, on the IOP in a sample of visually normal subjects. METHOD In a random sample of 120 young visually normal subjects (divided equally amo...
