BACKGROUND The role of plasma cholesterol in impairing arterial function and elasticity remains unclear. We evaluated arterial stiffness, measured locally in the common carotid artery by high-resolution echo-tracking, and aortic stiffness, using carotid-femoral pulse wave velocity (PWV) (the "gold-standard" measurement of arterial stiffness), in(More)
Reproductive biology of the Japanese mitten crab Eriocheir japonica (de Haan, 1835) was studied in the northern part of its habitat. It was revealed that E. japonica from the water bodies of Primorye, in contrast to crabs in the central part of the habitat on the Japanese Islands, lays fewer eggs in the first clutch, does not have direct dependence between(More)
Functional activity of the CGABA(A)-receptor/Cl(-) ionophore complex was investigated the muscimol-stimulated entry of the radioactive isotope 36Cl(-) in synaptoneurosomes in changing the structure and permeability of neuronal membranes. Integrity of the membranes was damaged by removal of Ca(+2) and Mg(+2) from the incubation medium and by the method of(More)
We studied the effect of Cl(-) (10-75 mM) and HCO(3)(-) ions (10-25 mM) on the ATP-dependent GABA(A) receptor-coupled Cl(-) channel (Cl(-)-ATPase) in rat brain plasma membranes. The total enzyme activity was detected in the presence of both anions at a Cl(-)/ HCO(3)(-) ratio of 5:1 (Cl(-), HCO(3)(-)-ATPase). Specific inhibitors of P-type transport ATPases(More)
Experiments on Wistar rats showed that basal and muscimol-induced 36Cl- entry into synaptoneurosomes isolated from the brain cortex decreased after kindling (30 mg/kg pentylenetetrazole intraperitoneally for 30 days) in animals with seizure severity score 4-5. Changes in Cl- conduction during kindling are discussed.
Muscimol-stimulated Cl- conductance of synaptoneurosomes from the cerebral cortex of Wistar rats increased during the early stage of pharmacological kindling not inducing the seizure response in animals. Picrotoxin, bicuculline, and pentylenetetrazole potentiated inhibition of muscimol-dependent 36Cl- entry into synaptoneurosomes, which attested to(More)
Experiments on Wistar rats showed a decrease in basal and muscimol-stimulated 36Cl(-) entry into synaptoneurosomes isolated from the cerebral cortex during the middle stage of kindling (30 mg/kg pentylenetetrazole intraperitoneally for 14 days) characterized by the development of convulsions of higher (2 points) severity in comparison with the previous(More)
