OBJECTIVES Cold exposure induces glycogen and lipid depletion in the liver and the adrenal gland, respectively. However, no previous study has determined the effects of electrical countershock on those tissues. We aimed to evaluate the effects of electrical countershock on lipid depletion in the adrenal gland and on glycogen depletion in the liver. METHODS We used 40 male Wistar rats divided ...

The amplified fragment length polymorphism (AFLP) assay is an efficient method for the identification of molecular markers, useful in the improvement of numerous crop species. Bulked Segregant Analysis (BSA) was used to identify AFLP markers associated with water-stress tolerance in barley, as this would permit rapid selection of water-stress tolerant genotypes in breeding programs. AFLP marker...

vetiver grass is known to survive under diverse soil and water conditions. in order to test its potential of salinity and aridity tolerance ability, the effect of salinity and aridity stress on the growth of the vetiveria zizanioides was studied by growing plants in arid soils that receiving salinity stress. the experiment was conducted in a greenhouse, arrangement in a completely randomized de...

The purpose of the present study was to investigate the limits of irrigationwater salinity and soil water content for growth inhibition of vetiver. Moreover,different models were studied to describe the root water uptake and plant topgrowth under salinity and water stresses in a pot experiment. Irrigation treatmentsconsisted of three irrigation intervals (3, 6 and 9-day). The salinity levels of...

lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. in this paper, the environmental problems of lead and zinc production in calcimin plant are expressed and life cycle assessment of this plant is assessed. the data regarding the amount of induced global warming and pollution, acidification, and depletion...

Sap flow, and atmospheric and soil water data were collected in closed-top chambers under conditions of high soil water potential for saplings of Liquidambar styraciflua L., Quercus phellos L. and Pinus taeda L., three co-occurring species in the southeastern USA. Responses of canopy stomatal conductance (g(t)) to water stress induced by high atmospheric water vapor demand or transpiration rate...

This study was undertaken to verify the effects of chronic stress and lithium treatments on the hippocampal Na+,K(+)-ATPase activity of rats, as well as to investigate the effects of stress interruption and post-stress lithium treatment on this enzyme activity and on spatial memory. Two experiments were carried out; in the first experiment, adult male Wistar rats were divided into two groups: c...

in this study the effect of nitric oxide synthesis inhibition on stress-induced gastric damage was evaluated in bile duel ligated, sham operated and unoperated rats. animals were injected intraperitoneally with ng-nitro-l-arginine methylester (l-name), 40 mglkg, l-argininc, 200 mg/kg or saline, 30 min before water-immersion stress. one hour after water immersion, the animals were killed and the...

ABSTRACT: Recent theoretical work on stream depletion and water level responses to pumping a well near a stream include the (semi-) analytical solutions by Hunt (1999), Zlotnik and Huang (1999), and Butler et al. (2001). Yet, few field studies assessed the limiting assumptions and physical concepts inherent in the theoretical models. A long-term study of stream depletion under typical condition...

this experiment aimed to determine evapotranspiration, and responses of some yield and quality parameters of subsurface drip irrigated broccoli (brassica oleraceae l.). treatments included water application when available soil moistures were depleted 30, 40, and 50% during both spring and autumn cultivations. under a semi-arid climatic condition of tokat, turkey, the experiment was carried out ...
