reliable estimates of runoff are required as a part of the information sets that help watershed managers make informed decisions on water resources planning and management. this study was carried out in shafaroud watershed located in the north of iran. in order to achieve the best runoff simulation in the study area, first rainfall data of four stations during 1998 to 2011 were collected and co...

alpha-1-proteinase inhibitor (api) is one of the acute phase proteins. following an inflammatory stimuli the concentration of api increased up to four folds. accompanying these quantitative changes, there is qualitative alterations in the structure of carbohydrate moiety (glycosylation). to determine the alterations in the glycosylation of api in inflammation, api was isolated from the sera of ...

OBJECTIVE The purpose of this project was to examine the effects of estradiol (E2) and progesterone (P) on the proliferation of HeLa cells. E2 promoted and P inhibited the proliferation of HeLa cells. MATERIALS AND METHODS Then, we tested the consequence of combining the different activities of E2 + P. RESULTS We found that P inhibited the proliferative effect of E2 on HeLa cells. Analysis ...
