Two strains of obligate chemolithoautotrophic sulfur-oxidizing bacteria were isolated from soda-lake sediments by enrichment culture with thiocyanate and nitrate at pH 9.9. The isolates were capable of growth with thiocyanate or thiosulfate as electron donor, either aerobically or anaerobically, and with nitrate or nitrite as electron acceptor. Cyanate was identified as an intermediate of thioc...
Quaternary climatic changes have been recognized to influence the distribution patterns and evolutionary histories of extant organisms, but their effects on alpine species are not well understood. To investigate the Pleistocene climatic oscillations on the genetic structure of amphibians, we sequenced one mitochondrial and three nuclear DNA fragments in Nanorana parkeri, a frog endemic to the T...
background: the clinical significance of antiphospholipid antibodies in patients with chronic hepatitis c virus (hcv) and some other viral infections is controversial. objective: to study the prevalence of anticardiolipin antibody (acla) and antibeta2glycoproteini antibody (antibeta2gpi antibody) in hcv and hepatitis b virus (hbv) infected patients and its association with liver clinical parame...
Emerging evidence suggests that mitochondrial dysfunction contributes to the pathophysiology of epilepsy. Recurrent mitochondrial Ca2+ ion load during seizures might act on mitochondrial membrane potential (DeltaPsim) and proton motive force. By using electrophysiology and confocal laser-scanning microscopy, we investigated the effects of epileptiform activity, as induced by low-Mg2+ ion perfus...
Onset of the mitochondrial permeability transition (MPT) is the penultimate event leading to lethal cellular ischemia-reperfusion injury, but the mechanisms precipitating the MPT after reperfusion remain unclear. Here, we investigated the role of mitochondrial free Ca(2+) and reactive oxygen species (ROS) in pH- and MPT-dependent reperfusion injury to hepatocytes. Cultured rat hepatocytes were ...
Muscle contraction requires ATP and Ca(2+) and, thus, is under direct control of mitochondria and the sarcoplasmic reticulum. During postnatal skeletal muscle maturation, the mitochondrial network exhibits a shift from a longitudinal ("longitudinal mitochondria") to a mostly transversal orientation as a result of a progressive increase in mitochondrial association with Ca(2+) release units (CRU...
Previous experiments in cultures of neonatal rat myocytes demonstrated that the shape of Cai(2+) transients measured using high-affinity Ca(2+)-sensitive dyes may be misrepresented. The purpose of this study was to examine the role of dye affinity in Cai(2+) measurements in intact adult cardiac tissue by comparing optical recordings obtained with high- and low-affinity dyes. Experiments were ca...
