In this report we examined the effects of a discontinuous radio frequency (RF) signal produced by a GSM multiband mobile phone (900/1,900 MHz; SAR approximately 1.4 W/kg) on Drosophila melanogaster, during the 10-day developmental period from egg laying through pupation. As found earlier with low frequency exposures, the non-thermal radiation from the GSM mobile phone increased numbers of offsp...

background: the goal of antivenom administration for snake-bitten patients is to achieve therapeutic response (initial control), which means reversal of the venom-induced effects through neutralizing the venom. the aim of this study was to identify snakebite prognostic factors of weak therapeutic response prior to antivenom administration. methods: this was a retrospective study of patients wit...

BACKGROUND The mammalian response to stress results in the activation of stress-activated protein kinases (also known as cJun N-terminal kinases; SAPKs or JNKs), which are a sub-group of the mitogen-activated protein (MAP) kinase family. The SAPKs are involved in the upregulation of activity of the transcription factor AP-1 by post-translational modification of two of its components, cJun and A...

Chemotaxis of rabbit mononuclear cells was studied by the micropore-filter technique. Mononuclear cells obtained from mineral oil-induced peritoneal exudates respond chemotactically to rabbit serum treated with immune complexes or with streptokinase and plasminogen, to soluble factors produced by bacteria, and to lysates obtained from rabbit neutrophils. The first chemotactic factor requires he...
