Ecto-ATPase and ecto-ATP-diphosphohydrolase are co-localized in rat hippocampal and caudate nucleus synaptic plasma membranes
(Physiological Research, 2003)
Enzymes that hydrolyze extracellular ATP, i.e. ecto-ATPase and ecto-ATP diphosphohydrolase (ATPDase), can be differentiated by ability of the latter to hydrolyze ADP and by slightly different kinetic properties of the two ...
The modulatory effect of estradiol benzoate on superoxide dismutase activity in the developing rat brain
(Brazilian Journal of Medical and Biological Research, 2003)
The sensitivity of copper,zinc (CuZn)- and manganese (Mn)-superoxide dismutase (SOD) to exogenous estradiol benzoate (EB) was investigated in Wistar rats during postnatal brain development. Enzyme activities were measured ...
Apoptotic versus genotoxic potential of antimtumor agents: a concept of duality in unity
(Medical Hypotheses, 2003)
Recent advances in anti-tumor therapy have raised a problem of secondary tumors and tumor resistance. Secondary tumors induced by chemotherapeutic agents as a consequence of primary therapy have poor prognostic outcome. ...
The effects of microalloying with silicon and germanium on microstructure and hardness of a commercial aluminum alloy
(Journal of the Serbian Chemical Society, 2003)
The effect of small additions of Si and Ge on the microstructure and hardness was investigated during aging of a commercial 2219 aluminum alloy It was found that for the same level of microalloying in alloy 2219SG (containing ...
Unidirectional stripping extraction from a cyclotron which accelerates light as well as heavy ions
(Physical Review Special Topics - Accelerators and Beams, 2003)
The VINCY Cyclotron (VINca CYclotron) is a multipurpose machine intended to accelerate light as well as heavy ions. To extract heavy ions with low energy and light ions an extraction system with stripping foil is used. ...
Effect of curing time on the fraction of Cs-137 from cement matrix
(Annals of Nuclear Energy, 2003)
To assess the safety of disposal of radioactive waste material in concrete, curing conditions and time of leaching radionuclides Cs-137 have been studied. Leaching tests in concrete were carried out in accordance with a ...
Laser interaction with some Bi-ferrites
(Journal of Materials Science Letters, 2003)
Criticality safety of low-enriched uranium and high-enriched uranium fuel elements in heavy water lattices
(Nuclear Science and Engineering, 2003)
The RB reactor was designed as a natural-uranium, heavy water, nonreflected critical assembly in the Vinca Institute of Nuclear Sciences, Belgrade, Yugoslavia, in 1958. From 1962 until 2002, numerous critical experiments ...
In vivo monitoring of chlorophyll fluorescence response to low-dose gamma-irradiation in pumpkin (Cucurbita pepo) leaves
(Luminescence, 2003)
The effect of gamma-irradiation on the in vivo-measured chlorophyll fluorescence in a pumpkin leaves (Cucurbita pepo) has been investigated. Plants were grown in the same environment, then divided into several groups and ...
Baseline micronuclei in fetal lymphocytes-a higher frequency in females relative to males
(Korean Journal of Genetics, 2003)
This study provides information concerning base-line micronuclei (MN) and sister-chromatid exchanges (SCEs) in human-fetal lymphocytes. Fetal cord blood (75 samples) were used for purposes of prenatal diagnosis; small ...
