Exposure of six wheat (Triticum aestivum L.) and one rye (Secale cereale L.) cultivar to 40% relative humidity for 24 hours induced the same degree of freezing tolerance in seedling epicotyls as did cold conditioning for 4 weeks at 2 degrees C.Frost hardiness varietal relationships were the same in desiccation-stressed and cold-hardened seedlings. Drought stress could, therefore, be used as a r...

introduction: methadone has been used as a drug to detoxify opioid tolerance. naloxane precipitated morphine withdrawal behaviours were attenuated by venlafaxine as an antidepressant. on the contrary, after detoxifying the opioids, spontaneous withdrawal syndrome may occur with pain sensitivity. therefore the present study aimed to examine the effects of chronic methadone (70 mg/kg, in drinking...

since particulate matter (total suspended particles and particulate matter with median aerodynamic diameter less than 10 µm) is one of the important pollutants in the ambient air of tehran, the capital of iran, organic substances, inorganic substances and lead levels in tsp and pm10, correlation between tsp and pm10 concentrations, ratio among the two fractions and relation between tsp and pm10...

background: benzene is one of the most widely used volatile organic compounds showing severely adverse effects on human health. removing benzene from the airflow or controlling its amounts, is one of the issues put to discussion in the field of environmental engineering. the objective of this study was to examine the efficacy of the ultraviolet-c (uv-c) radiations on removing benzene from the a...

Under the effect of global warming, more precipitation will shift to rainfall in cryospheric regions. Considering influence type on surface energy and mass cycles, it is important determine specific features classify key areas correctly. We analyzed monthly distribution, variations each type’s annual days, trends based daily air temperature observations from six tripolar stations. The results i...

In growing plasmodia of the myxomycete Physarum polycephalum (G2-phase), three distinct classes of nuclei with a relative DNA content of 1x, 2x, and 4x are observed in the presumed haploid strain CL. The 2x and 4x species comprise up to 35% and 5% of the nuclei. Quantitative cytofluorometric studies of nuclei isolated in either G2- or S-phase or after FUDR treatment (G1 arrest) show that the th...
