1 Introduction Many languages systematically avoid stressing final syllables. This dispreference for final stress can be seen both in languages with weight-insensitive stress and those with weight-sensitive stress. For example, many languages with weight-insensitive stress, e.g. Nahuatl (Wolgemuth 1981), Polish (Comrie 1976), regularly stress the penultimate syllable, the syllable closest to th...

Proteolytic cleavage of the dynamin-like guanosine triphosphatase OPA1 in mitochondria is emerging as a central regulatory hub that determines mitochondrial morphology under stress and in disease. Stress-induced OPA1 processing by OMA1 triggersmitochondrial fragmentation, which is associated with mitophagy and apoptosis in vitro. Here, we identify OMA1 as a critical regulator of neuronal surviv...

standardization of induction of oxidative stress with fenton mixture (fm) in isolated perfused rat kidney and the antioxidant effect of terminalia arjuna bark in the isolated oxidatively stressed rat kidney has been evaluated. six groups each containing eight isolated perfused rat kidneys were used for the present study and the oxidative stress was induced by perfusing the isolated kidneys with...

dobutamine stress echocardiography (dse) has been widely used as a diagnostic and prognostic modality in the management of stress. dse is associated with limited complications and adverse effects on the health of patients. in this case report, we described a 42-year-old female patient with dobutamine-induced coronary artery spasm with history of exertional dyspnea, which had deteriorated recent...

Background: Probiotics have attracted a great attention aiming to develop natural non-toxic antioxidants, because of their role in decreasing the risk of reactive oxygen species (ROS) accumulation. Objectives: The purpose of this study was to assess the antioxidant activity of a probiotic Streptococcus salivarius ssp thermophillus (St.sa) and to evaluate its protective effect against the ...

The effect of chronic nicotine treatment on chronic psychosocial stress-induced impairment of short-term memory and long-term potentiation (LTP) was determined. An "intruder" stress model was used to induce psychosocial stress for 4-6 wk, during which rats were injected with saline or nicotine (1 mg/kg s.c.) twice a day. The radial arm water maze memory task was used to test hippocampus-depende...

Excess concentrations of catecholamines in pheochromocytoma can cause various clinical manifestations. There are few reports of pheochromocytoma presented with stress-induced cardiomyopathy (catecholamine-induced cardiomyopathy) after mild stress and the case of pheochromocytoma associated with nonocclusive stroke is more uncommon. We report a case of pheochromocytoma manifested repeated stress...
