Cassava (Manihot esculenta Crantz) plant resists water-deficit stress by shedding leaves leading to adaptive water-deficit condition. Transcriptomic, physiological, cellular, molecular, metabolic, and transgenic methods were used to study the mechanism of cassava abscission zone (AZ) cell separation under water-deficit stress. Microscopic observation indicated that AZ cell separation initiated ...

We explored the neurochemical mechanism of electroacupuncture's (EA) protective effect on brain function in focal cerebral ischemia rats, using cerebral ischemia/reperfusion rats established by the middle cerebral artery occlusion (MCAO) method. Adult male Sprague-Dawley rats were randomly divided into four groups: Sham, Sham+EA, MCAO and MCAO+EA. The rats in Sham+EA and MCAO+EA were accepted E...

We compared the metabolic responses of leaves and roots of two Eucalyptus globulus Labill. clones differing in drought sensitivity to a slowly imposed water deficit. Responses measured included changes in concentrations of soluble and insoluble sugars, proline, total protein and several antioxidant enzymes. In addition to the general decrease in growth caused by water deficit, we observed a dec...

PURPOSE The objective of this study is to compare the physiological capacity and training characteristics of the world's six highest ranked female cross-country skiers (world class (WC)) with those of six competitors of national class (NC). METHODS Immediately before the start of the competition season, all skiers performed three 5-min submaximal stages of roller skiing on a treadmill for mea...

Article history: Received: 23 Apr 2011 Accepted: 26 Feb 2012 Available online: 18 Nov 2012 ZJRMS 2013; 15(5): 1-5 Background: Recent studies have shown that normobaric hyperoxia compared with normobaric normoxia can reduce the damages resulting from the stroke. The purpose of this study is to investigate the effects of oxygen radicals in reduction of cerebral edema caused by normobaric hyperoxi...

BACKGROUND Atrial fibrillation (AF) is associated with impaired exercise capacity. Oxygen uptake (VO2) kinetics determines cardiopulmonary performance during submaximal exercise, which may be impaired in patients with AF. AIM To study oxygen kinetics and cardiopulmonary performance in patients with AF without structural heart disease and the effects of oral sotalol on these parameters. PATI...

Aeration is one of the most important factors in biological wastewater treatment process. Through aeration, oxygen is supplied to the bacteria to allow their respiration to proceed rapidly and satisfy the biochemical oxygen demand (BOD). This study was carried out to determine the biological growth in aerated palm oil mill effluent (POME) when subjected to aeration using air of different oxygen...

This paper reports the outcome after carbon monoxide poisoning in 31 consecutive patients treated with mechanical ventilation and hyperbaric oxygen therapy, compared with another study of mechanically ventilated patients treated with normobaric oxygen. We found 16.1% hospital mortality and 3.8% severe short-term memory loss, compared with 30% hospital mortality and 20% incidence of serious neur...
