Background/Aim. The reaction of an organism to radiation depends on the level irradiation and sensitivity affected tissue cells. biological effects cells tissues are proportional absorbed energy. aim our study was examine hypofunction pituitary gland, previously irradiated with x-rays, growth rat?s craniofacial stomatognathic system as well tibia. Methods. A total dose x-rays 27.92 Gy applied i...

We have used both a rat orthotopic hepatocellular carcinoma model and a mouse allograft tumor model to study liver tumor ablation with nanosecond pulsed electric fields (nsPEF). We confirm that nsPEF treatment triggers apoptosis in rat liver tumor cells as indicated by the appearance of cleaved caspase 3 and 9 within two hours after treatment. Furthermore we provide evidence that nsPEF treatmen...

Objective: The role of growth factors, including vascular endothelial growth factor of activated omentum on mitosis is clearly known, though not on all the aspects of in vitro oocyte maturation. This study was designed to assess the effect of activated-omental extract (AOE) on in vitro maturation (IVM) of rat cumulus-oocyte complexes (COCs). Materials and Methods: In this experimental study, th...

This study aimed to evaluate the inhibitory effect of lentinan on the growth of rat C6 glioma cells in vitro. After C6 cells were treated with lentinan for 24, 48 and 72 h respectively, cell activity was detected using MTT assay. After the cells were conducted Annexin V/PI double staining or PI single staining, apoptosis and cell cycle were detected by a flow cytometry. The activities of C6 cel...

Ferritin was isolated from six Morris hepatomas with growth rates ranging from 3 to 12 days doubling time and also from regenerating rat liver. The ferritins from all six tumors differed electrophoretically from normal rat liver ferritin. Five of them migrated identically, and antigenic studies on four confirmed the change in protein structure. In response to iron treatment of the host, more fe...

the aim of this study is to investigate the share of total factor productivity growth (tfpg), labor force growth and physical capital growth on the value added growth of non-oil sector by applying the cob-douglass production function during the third, fourth and fifth development plans before the islamic revolution of iran (1342-1356), and during the first, second, third and forth economic, soc...

The replicative responses of suckling and adult rat hepatocytes in primary culture to growth-stimulating factors were compared. By addition of L-proline alone, the [3H]-thymidine labeling of suckling rat hepatocytes was dramatically enhanced, but that of adult ones was not. Epidermal growth factor (EGF), insulin, triiodothyronine (T3) and glucagon also enhanced the labeling of suckling rat hepa...

Individuals differ in both inherited and acquired abilities, but only the latter differ among countries and time periods. Human capital analysis deals with acquired capabilities which are developed through formal and informal education at school and at home, and through training, experience, and mobility in the labor market. Just as accumulation of personal human capital produces individual eco...
