[ 1 ] - The Effects of Buthotus schach Scorpion Venom on Electrophysiological Properties of Magnocellular Neurons of Rat Supraoptic Nucleus
Potassium channels are trans-membrane proteins, which selectively transport K+ ions across cell membranes and play a key role in regulating the physiology of excitability cells and signal transduction pathways. Bothutous Schach (BS) scorpion venom consists of several polypeptides that could modulate ion channels. In this study, the effects of BS crude venom on passive and active electrophysiolo...
[ 2 ] - Impact of Corporate Reputation on Brand Differentiation : An Empirical Study from Iranian Pharmaceutical Companies
The influence of company reputation, or what is often referred to as corporate reputation on branding strategy and producing intangible asset for different industries has been researched in western countries, but there is a gap for the generalizability of findings to countries out of the United State and Europe . To establish the western researcher’s external validity of theories in other count...
[ 3 ] - Anticancer Activity a of Caspian Cobra (Naja naja oxiana) snake Venom in Human Cancer Cell Lines Via Induction of Apoptosis
Abstract Cancer is the leading cause of death worldwide. Current anticancer drugs involve various toxic side effects; efforts are ongoing to develop new anticancer agents especially from the screening of natural compounds. Present study investigated cytotoxic effects and mode of cell death induced by the Caspian cobra venom in some human cancer cell lines. Cytotoxic effects of snake venom toxin...
[ 4 ] - Cytotoxic Effect of Iranian Vipera Lebetina snake Venom on HUVEC Cells
Objective: Envenomation by heamotoxic snakes constituted a critical health occurrence in the world. Bleeding is the most sever consequence following snake bite with viperid and crothalid snakes. It is believed that the degradation of vascular membrane caused hemorrhage; in contrast, some suggested that direct cytotoxicity has role in endothelial cell disturbances. This study was to evaluate the...
[ 5 ] - FTIR Microspectroscopy Reveals Chemical Changes in Mice Fetus Following Phenobarbital Administration
Phenobarbital is a phenobarbiturate used as a sedative, anticonvulsant, or hypnotic with the doses prescribed and can cause teratogenic effects. The goal of this study was to examine an alternative method for the recognition of the mechanism or the bimolecular potential changes in mice fetus caused by Phenobarbital using FTIR micro spectroscopy. The mice were injected with Phenobarbital (120mg/...
[ 6 ] - Immunomodulatory Effects of Bee Venom in Human Synovial Fibroblast Cell Line
As in Iranian traditional medicine, bee venom (BV) is a promising treatment for the rheumatoid arthritis (RA) which is considered as a problematic human chronic inflammatory disease in the present time. Smoking is considered to be a major risk factor in RA onset and severity. The main aim of this study is to investigate the effects of BV on cigarette smoke-induced inflammatory response in fibro...
[ 7 ] - FTIR-Microspectroscopy Detection of Metronidazole Teratogenic Effects on Mice Fetus
Metronidazole is used to treat trichomoniasis, bacterial vaginosis, and other diseases. There are controversy aspects about its teratogenicity. A teratogenic agent can alter morphology or subsequent function of the fetus. The aim of this study was to examine an alternative method for the recognition of the mechanism or the bimolecular potential changes in mice fetus caused by Metronidazole usin...
[ 8 ] - Effects of Odontobuthus Doriae Scorpion Venom on Mouse Sciatic Nerve
Temporary paralysis is a rare manifestation of envenoming following the yellow Iranian scorpion, Odontobuthus doriae (O. doriae). Thus, to elucidate the underlying mechanism, we investigated the neurotoxic effect of venom in the sciatic nerve, the possible mechanism in a mice model. The neurotoxicity and temperature effects in the venom-induced neurotoxicity were examined using the mouse sciati...
[ 9 ] - Silo Effect a Prominence Factor to Decrease Efficiency of Pharmaceutical Industry
To be sure, all the industries try to be involved in globalization with a constant trend to find out ways to increase productivity across different functions within an organization to maintain competitive advantage world. Pharmaceutical industries are not exceptional and further are based on fragmentation. So these kind of companies need to cope with several barriers such as silo mentality that...
[ 10 ] - Partial Fractionation of Venoms from Two Iranian Vipers, Echis carinatus and Cerastes persicus Fieldi and Evaluation of Their Antiplatelet Activity
Platelet aggregation inhibitory effect and anticoagulant properties of fractions separated from the venoms of Cerastes persicus fieldi and Echis carinatus were investigated.
