re-vegetation of bare soil is believed to increase, or at least maintain the organic matter levels of soil. the aim of this study was to investigate the soil characteristics changes, nutrient pool sizes and their availability under mid canopy, and canopy gap positions of saltbush in an area re-vegetated with atriplex lentiformis. some of the physical and chemical soil characteristics (the parti...

Background: The effects of aqueous extract of Fadogia agrestis stem at the doses of 18, 36, and 72 mg/kg body weight on alloxan-induced toxicity was investigated in Wistar rats. Methods: In total, 35 rats of both sexes (132.80±7.22g) were randomized into five groups (A-E): animals in group A received 0.5 ml of distilled water orally on daily basis for 15 days while the alloxanized rats in gr...

The aim of this study was to perform ICP analysis of the content of Pb, Mn, Cu, Zn, Fe, K, Na, P, MgandCa in wildediblemushrooms Boletus pinophilus. The samples were collected from the Batak mountain, Bulgaria. The preparation of samples was done by microwave mineralisation. Allmineral concentrations were determined on a dry weight basis (d.w.). The average content of studied elements: Pb, Mn, ...

The previous experiments have demonstrated that NMDA receptor antagonists and nitric oxide synthase (NOS) inhibitors have antidepressant- and anxiolytic-like activities in rodents. Moreover, chronic treatments with these agents result in down-regulation of beta-adrenoceptors in the brain cortex with a magnitude comparable to clinically effective antidepressants. However, still little is known a...

To test whether mineral recommendations for horses are likely to guarantee adequate mineral provision for tapirs (Tapirus spp.), we investigated the apparent absorption (aA) of macro and micro-minerals in 18 tapirs from five zoological institutions in a total of 24 feeding trials with total faecal collection. Samples of feeds and faeces were analysed for Ca, P, Mg, Na, K, Fe, Cu and Zn. The res...

in this study, the effects of long term use of urban wastewater (over 40 years) on soil salt content and related parameters were evaluated in the lands south of tehran. for this analysis, kriging methods were tested. according to the suitable model indices, ordinary kriging (ok) was suitable for ph, clay, na+, mg2+ and sodium adsorption ratio (sar) interpolation; log-normal kriging (log-normal ...

The neutral exchange between Na+ or K+ ions and protons across the mitochondrial membrane was studied by means of passive swelling in isotonic acetate salts. The selectivity for Na+ over K+ was approximately 50: 1. The rate of Na+-dependent swelling mediated by the natural exchange system was sensitive to pH and inhibited 70% or more by 20 rnM Mgr+. Physiological Mg 2+ levels, however, inhibite...
