In this study, evidence for a factor secreted by bovine hypophyseal pars tuberalis that stimulates luteinizing hormone (LH) release from rat pars distalis cells is shown. The secretion products of bovine pars tuberalis cells into the culture medium were assayed on dispersed rat pars distalis cells in 30 min incubations and superfusion experiments. The culture medium from pars tuberalis total ce...

One of Iran's oil and gas reservoirs' characteristics is that some huge reservoirs are shared with its neighbors. common fields neighbors among the most valuable income national wealth sources, so production delays cause irreparable damage to economy. Therefore, this research attempts use game theory investigate optimal onshore offshore. For purpose, existing revenues costs have been identified...

 Events leading up to the release of toxic chemicals in the processing plants are one of the main hazards of chemical industries that can endanger employees and also people in neighborhood. In this study, DOW's Chemical Exposure Index (CEI) is used to determine hazard distances of possible toxic chemical releases in one of the South Pars gas refineries. To...

BACKGROUND Morphological variations have arisen due to diverse environmental conditions. Application of cytoarchitectonic criteria permits the delineation of distinct nuclear complexes from the brain region. PURPOSE Very less information is available on the cytoarchitectonic pattern of the brain, of the giant snake headed murrel, Channa marulius. The murrel is much neglected in neuroanatomica...

As little is known about the neurotoxicity of histological structure brain, this study focuses on side four- to six-month-old adult Wistar rat brains, which were examined after 0.1 mg\g organophosphate had been administered orally. In study, lesions mainly localized at hippocampus and substantia nigra (compacta pars) region. Distinct areas necrotic apoptotic tissues detected in CA1, CA2, dentat...

Aim To understand better the representation of arctic tundra vegetation by pollen data, we analysed pollen assemblages and pollen accumulation rates (PARs) in the surface sediments of lakes. Location Modern sediment samples were collected from seventy-eight lakes located in the Arctic Foothills and Arctic Coastal Plain regions of northern Alaska. Methods For seventy of the lakes, we analysed po...
