conclusions due to the long exposure to the loud noise during the day, hearing loss in drivers is significant. the left ear displays greater loss than the right ear. therefore, strategies to prevent hearing loss in drivers could include education, lifestyle changes and compliance issues related to hearing health, use of personal protective equipment, conducting periodic examinations and early t...

To date, cultivated male Japanese eels have not matured sexually in captivity under normal conditions. However, spermatogenesis and spermiation can be induced by the injection of gonadotropins. During this study, most males spermiated after the fifth or sixth weekly injection of human chorionic gonadotropin (HCG; 1 IU/g BW/wk) and the milt weight gradually increased as the number of injections ...

A testicular feed back on the hypothalamo-pituitary system was studied in male rainbow trout (Salmo gairdneri) after bilateral castration and steroid or testicular supplementation. Experiments were carried out at various periods of the spermatogenetic cycle ; in March-April (resting stage), June (initiation of spermatogenesis), October (end of spermatogenesis and before spermiation), and Decemb...

Disubstituted haloacid by-products of drinking water disinfection such as dibromoacetic acid and dichloroacetic acid have been shown to perturb spermatogenesis and fertility in adult male rats. In the present study we sought to establish whether equimolar exposure to bromochloroacetic acid (BCA), a prevalent by-product in finished drinking water, is also capable of disrupting these endpoints, a...

conclusions misoprostol plus letrozole was more effective for inducing abortion in the first trimester of pregnancy compared to misoprostol alone. results the complete abortion rate was 69.7% in the misoprostol and letrozole group and 30.3% in the misoprostol group. incomplete abortion was 32.4% in the misoprostol and letrozole group, and 67.6% in the misoprostol group (p = 0.004). bleeding, ce...

background: nowadays, magnetic nanoparticles (mnps) have received much attention because of their enormous potentials in many fields such as magnetic fluid hyperthermia (mfh). the goal of hyperthermia is to increase the temperature of malignant cells to destroy them without any lethal effect on normal tissues. to investigate the effectiveness of cancer therapy by magnetic fluid hyperthermia, fe...

exercise induced asthma (eia) is a transient increase in airway resistance after intensive exercise and can be measured as a decline in forced expiratory volume in one second (fev1). the condition is due to increased training load and inhalation of cold and dry air. several studies have shown that eucapnic voluntary hyperpnea challenge test (evh test) is a very sensitive and specific diagnostic...

The response of climate to perturbations in GHGs is location dependent. Six experiments: control (CTRL); double CH4; double CO2; double N2O; halved CFC11 and halved CFC12 were carried out to reveal the local area response to different GHGs levels in the atmosphere over West Africa. Double CH4, CO2 and N2O generally induce wetness but they also induce localized dryness at the hilly and mountaino...
