Vortex complexes in two-dimensional optical lattices linearly coupled at a single site
(Physica Scripta, 2013)
We investigate the stability and dynamical properties of complexes consisting of two identical vortices with topological charges S = 1 and 2 in the system of two linearly on-site-coupled two-dimensional (2D) vortices. The ...
Kinetic characterization of ecto-nucleoside triphosphate diphosphohydrolases in brain nerve terminals during rat postnatal development
(Russian Journal of Physical Chemistry A, 2011)
A family of enzymes named ecto-nucleoside triphosphate diphosphohydrolase (NTPDases) catalyzes the termination of ATP and ADP actions. Three different NTPDases (NTPDase 1-3), differing in their preference for a substrate, ...
Inhibition of Mitochondrial Na-Dependent Ca2+ Efflux from Rat Brain Stem By 17 Beta-Estradiol
(Archives of Biological Sciences, 2009)
The role of membrane-bound estradiol in modulation of mitochondrial Ca2+ flux in nerve endings isolated from rat brain stem was examined. Physiological concentrations of 17 beta-estradiol bind specifically to isolated ...
Effect of acute stress on NTPDase and 5 -nucleotidase activities in brain synaptosomes in different stages of development
(International Journal of Developmental Neuroscience, 2010)
The aim of the present study was to examine the effect of acute restraint stress on rat brain synaptosomal plasma membrane (SPM) ecto-nucleotidase activities at specific stages of postnatal development (15-, 30-, 60- and ...
Time-Course of Hypothalamic-Pituitary-Adrenal Axis Activity and Inflammation in Juvenile Rat Brain After Cranial Irradiation
(Cellular and Molecular Neurobiology, 2012)
Recent studies reported that exposure of juvenile rats to cranial irradiation affects hypothalamic-pituitary-adrenal (HPA) axis stability, leading to its activation along with radiation-induced inflammation. In the present ...
ATP and ADP hydrolysis in cell membranes from rat myometrium
(Molecular and Cellular Biochemistry, 2012)
Extracellular nucleotides affect female reproductive functions, fertilization, and pregnancy. The aim of this study was to investigate biochemical characteristics of ATP and ADP hydrolysis and identify E-NTPDases in ...
Effect of Sex Hormones on Plasma Phospholipid Fatty Acid Composition in Intact Rats and Rats With Bilaterally Occluded Carotid Arteries
(Physiological Research, 2014)
The effects of 8-days treatment with 17 alpha-estradiol (33.3 mu g/kg) and progesterone (1.7 mg/kg) on plasma lipids and fatty acid composition of plasma phospholipids were examined in intact (INT) and bilaterally common ...
Effects of acute gamma-irradiation on extracellular adenine nucleotide hydrolysis in developing rat brain
(Russian Journal of Physical Chemistry A, 2009)
Cell membrane is highly sensitive to irradiation which, acting directly or indirectly, may disturb functions of constitutive proteins including membrane enzymes. Plasma membrane surface-located enzyme chain of ecto-nucleotide ...
Effect of EDTA on copper-induced inhibition of rat myometrial ecto-ATPase activity
(Russian Journal of Physical Chemistry A, 2009)
The aim of this study was to examine in vitro chelators ability to prevent copper-induced inhibition of rat myometrial ecto-ATPase activity. The effects of increasing CuSO(4) concentrations, in the absence and presence of ...
Radiation-Mediated Induction of Apoptotic Cell Death in Rat Hippocampus
(Nuclear technology and radiation protection, 2013)
Ionizing radiation is commonly used in the treatment of brain tumors but it can impair cognitive functions, such as learning and memory. Since cognitive dysfunctions are predominantly result of cell death by apoptosis in ...
