Tests were carried out on sperm from 40 fertile and infertile men to evaluate 2 DNA in situ denaturation methods using acridine orange (AO; the modified Rigler-Roschlau method and the Tejada method), alongside routine aniline blue (AB) and toluidine blue (TB) tests in our modification, and in order to estimate and compare the practical value of different in situ cytochemical tests for sperm chr...

an ion imprinted polymer (iip) based on aniline-formaldehyde was synthesized and then modified with extra aniline as cross-linker in the presence and absence of sr (ii) as the template to produce ion imprinted poly(aniline-formaldehyde) (iipaf) and non imprinted poly(aniline-formaldehyde) (nipaf). the sorbent was characterized by fourier transform infrared spectroscopy and was used for solid ph...

Background: Acyclovir is asynthetic purin nucleoside analog,which has been reported to be very effective against the treatment of herpes simplex and varicella zoster infections. Acyclovir is known to be toxic to gonads, but available literature fails to provide the indepth analyses of damage.The aim of the present study was to evaluate the effect of Acyclovir on DNA damage and nuclear maturatio...

The development of the notochord, perichordal sheath and vertebrae was studied in C57BL/6 and Danforth's short-tail (Sd) mutant mice on days 9-14 of gestation, using histochemical stains to detect possible extracellular matrix (ECM) components or precursors. Stains used were periodic-acid Schiff (PAS) after diastase treatment (glycoproteins, neutral polysaccharides) and alcian blue (glycosamino...

Enhancement of aniline hydroxylation by Habu snake venom was studied in vitro. The fraction which was isolated from Habu venom through column chromatography caused the enhancement of aniline hydroxylation of hepatic microsomes obtained from untreated rats. This fraction was heat stable and free from phospholipase activity. Enhancement of aniline hydroxylation was not clear in crude Habu venom o...

The interactions of aniline with soil at an industrial spill site were investigated. Sorption of aniline to the soil was observed to occur through a two-step mechanism. The first step was an ion exchange process with the protonated amine serving as an organic cation. This step was influenced by solution pH and ionic composition. The second step was covalent bonding most likely with quinone moie...
