the effects of pesticide endosulfan (an organochlorine compound), on the ovaries of bluegill fish (lepomis macrochirus) were studied. exposures for 24 hs with histological preparations at 25% (0.25 î¼g/l), 75 % (0.75 î¼g/l), and 100 % (1 î¼g/l) sub lethal concentrations were examined. the control contained an abundance of the different stages of oocytes (oocytes i, ii, iii, and iv) and had an i...

due to importance of combination therapies in cancer treatment, this study was performed to find the effects of hyperthermia and neutron irradiation and heir combination on the human lymphocytes. blood samples were treated separately with 41.5 °c for 30 and 60 minutes, 43 °c for 15 and 30 minutes, as well as 10 cgy neutron irradiation. they also treated with hyperthermia followed by irradiation...

Introduction: Radiation from cell phones has been associated with an increased risk of cancer. The literature has reported evidence of certain biological effects resulting from exposure to various wavelengths, doses, and intensities of radiofrequency radiation. The present study aimed to evaluate the possible adverse effects of radiation from a GSM mobile phone operating at 900 MHz on human mel...

The loss of kernels lowers the yield, whereas damaged kernels reduce the grade of the harvested wheat. Standards established by the Canadian Grain Commission limit midge damage in No. 1 CWRS and No. 2 CWRS to 2 per cent and 8 per cent respectively, before grade is affected. Damage tolerances for amber durum are 2 per cent for No. 1 CWAD and 8 per cent for No. 2 CWAD. However, if disease associa...

Objective(s): Despite several proposed mechanisms for the pathophysiology of cardiorenal syndrome (CRS), the exact mechanism remains unclear. Nitrosative stress has been argued as a key mechanism recently. Nebivolol is a beta-blocker with nitric oxide (NO)-releasing effect. In the present study, NO-mediated effects of two different treatment regimes of nebivolol in CRS...

salinity is a major limitation ecological factor for plant development in arid and semi-arid regions. the ionic imbalance, deficiency of nutrients and degradation of plant metabolites are caused by saline conditions, are affected by the reduction ratio of potassium (k) then sodium (na). in this research foliar applications of humic acid (ha) for improve the absorption of k under salt stress was...

Background: The incidence of diabetes mellitus is rapidly increasing in the world. One of the complications of diabetes includes disturbance of the reproductive tract, such as infertility, erectile dysfunction, and endocrine disturbances. Nitric oxide (NO) is a free radical produced by most of cells including the human male and female reproductive tracts. NO has a dual role where low concentrat...
