Phase composition and fracture toughness of Si3N4-ZrO2 with CeO2 additions
(Ceramics International, 1999)
Zirconia toughened Si3N4 was prepared with addition of CeO2 by applying hot pressing technique. Phase composition, densification, fracture toughness and hardness were investigated as a function of hot pressing temperature ...
Genotoxicity of the anticoccidial agent salinomycin
(Acta Veterinaria, Beograd, 1998)
This report presents an analysis of genotoxic effects of the ionophoric antibiotic salinomycin commonly used in the control of coccidiosis. Mutagenic properties were determined, after application of increasing doses to ...
Spectrophotometric study of hexanitrocobaltate(III) ion spontaneous reduction in water-ethanol and water-acetone mixtures
(Spectroscopy Letters, 1998)
The kinetics of the spontaneous reduction of hexanitrocobaltate(III) ion have been investigated spectrophotometrically (lambda=360 nm at 298 K) in ethanol or acetone water mixtures containing 0, 10, 25 and 50 % of organic ...
Central and peripheral catecholamine stores in spontaneously hypertensive rats under immobilization stress
(Acta Veterinaria, Beograd, 1999)
The effects of increasing duration of immobilization stress (from 30 min to 240 min) on catecholamine stores in some central (hypothalamus, corpus striatum) and peripheral tissues (suprarenal glands, heart auricles) in ...
Radiosensitivity of human lymphocytes in vitro correlates more with proliferative ability of cells than with the incidence of radiation-induced damages of the genome
The purpose of this study was the estimate the extent of individual variability in radioresponse of human lymphocytes in vitro and to establish the reasons of variability. Individual variability in radiation-response was ...
Association of the insertion/deletion polymorphism at the angiotensin I-converting enzyme locus with arterial blood pressure: Population-based study
(Jugoslovenska Medicinska Biohemija, 1999)
We have determined frequencies of alleles and genotypes at angiotensinl-converting enzyme (ACE) locus by polymerase chain reaction (PCR) in the healthy population of Belgrade. We also studied the association of this ...
Effects of progesterone and estradiol benzoate on glutathione dependent antioxidant enzyme activities in the brain of female rats
(General Physiology and Biophysics, 1999)
The activities of glutathione dependent antioxidant enzymes were measured in subcellular fractions of whole brain homogenates prepared from ovariectomized (OVX) female rats, untreated or treated 2 h or 24 h prior to sacrifice ...
RuO2-TiO2 coated titanium anodes obtained by the sol-gel procedure and their electrochemical behaviour in the chlorine evolution reaction
(Colloids and Surfaces. A: Physicochemical and Engineering Aspects, 1999)
TiO2 and RuO2 sols were obtained from RuCl3 and TiCl3 aqueous solutions by condensation and forced hydrolysis at elevated temperature. The Ti supported coatings were obtained by the sol-gel method using a sol mixture in ...
A simple PCR with different 3 ends of the third primer for detection of defined point mutations: HCV genotyping as an example
(Clinical Chemistry and Laboratory Medicine, 1998)
In this article, we describe a useful modification of the polymerase chain reaction for amplification applicable to hepatitis C virus genotyping and determination of its subtypes. The method is fast, cheap and simple for ...
Diagnostic of astrophysical plasma in neighborhood of neutron stars
(IAU Symposia / International Astronomical Union, 1998)
