Bilodeau Centre de Recherche, Laboratoire d'hepatologie cellulaire, Hospital Saint-Luc (CHUM), Montreal, Quebec, Canada, Department of Organic Chemistry, University of Bremen, Bremen, Germany Introduction Mitochondrial damage is being recognized as a key step in liver injury associated with oxidative stress. Mitochondria also have necessary roles in the...
متن کاملExperimental hyperthyroidism-induced oxidative stress and impairment of antioxidant defence system in rat testis.
Short-term hyperthyroidism, induced by daily administration of T3 (20 microg/100g body weight) for one, three, and five days consecutively, modulates oxidative stress and antioxidant defence parameters in mitochondrial and postmitochondrial fractions of testis in adult rats. Alteration in antioxidant defences along with oxidative stress parameters in testis by thyroid hormone was found to be as...

متن کاملMechanisms of plant adaptation/memory in rice seedlings under arsenic and heat stress: expression of heat-shock protein gene HSP70
BACKGROUND AND AIMS Plants can withstand many abiotic stresses. Stress adaptation through retention of imprints of previous stress exposure has also been described in plants. We have characterized the imprint or memory of adaptive stress responses of rice seedlings to arsenic (As) and heat stress. METHODOLOGY Two-week-old rice seedlings (both with and without As) were given a 45 °C heat shock...
متن کاملPolyamines in Rice Seedlings under Oxygen-Deficit Stress.
Incubation of 3-d-old seedlings of Oryza sativa L. cv Arborio under anaerobic conditions, leads to a large increase in the titer of free putrescine while aerobic incubation causes a slight decrease. After 2 days, the putrescine level is about 2.5 times greater without oxygen than in air. The rice coleoptile also accumulates a large amount of bound putrescine and, to a lesser extent, spermidine ...
