The dental pattern is defined as the combination of distinct codes assigned to describe specific tooth conditions including virgin, missing, and restored teeth that comprise the complete dentition or from discrete groups of teeth. This pattern can be then compared to the dentition of individual/s in an attempt to determine positive identification. The aims of the present investigation were to s...

Blood volume expands significantly during pregnancy, but afferent signals from cardiac receptors are reduced. In addition, during exogenous volume expansion, right atrial pressure (RAP) increases more for equivalent volumes in pregnant animals, implying reduced atrial compliance. To examine possible gestational alterations in atrial dimension during volume expansion, we compared the effects of ...

BACKGROUND Extra virgin olive oil (EVOO) is fruit oil with rich source of monounsaturated fats and powerful antioxidants. It acts as hypolipidemic agent and significant decrease of plasma lipids level was observed with EVOO use. Atorvastatin is hypolipidemic drug commonly used for treatment of hyperlipidaemia. The purpose of this study was to determine & compare the lipid lowering effect of EVO...

The endogenous synthesis of lipids, which requires suitable dietary raw materials, is critical for the formation of membrane bilayers. In eukaryotic cells, phospholipids are the predominant membrane lipids and consist of hydrophobic acyl chains attached to a hydrophilic head group. The relative balance between saturated, monounsaturated, and polyunsaturated acyl chains is required for the organ...

Male Drosophila melanogaster that have courted newly-emerged males can modify their subsequent courtship behavior to avoid further courtship with immature males for up to 6 hr (previously reported). Here, it was hypothesized that such an experience-dependent modification would afford a mating advantage to normal males over males that carried a mutation that affects learning and memory. Coisogen...

Hines, Tina, and William A. Herzer. Effect of cardiac receptor stimulation on renal vascular resistance in the pregnant rat. Am. J. Physiol. Regulatory Integrative Comp. Physiol. 278: R171–R178, 2000.—Stimulation of cardiac receptors (CR) evokes blunted reflex reductions in mean arterial pressure (MAP) in pregnant compared with virgin rats. Because CR-mediated sympathoinhibition has preferentia...

Epithelial cells in explants from the mammary glands of euthyroid mature virgin mice are proliferatively dormant. They must undergo DNA synthesis and traverse the cell cycle in vitro before they are able to differentiate fully in response to insulin, hydrocortisone, and prolactin, and synthesize enzymatically active alpha-lactalbumin (measured as lactose synthetase activity). In contrast, gland...

The effect of temperature on male sexual displays is well documented but its role in mediating the differential mating success of males is less well established. Male sagebrush crickets Cyphoderris strepitans Morris and Gwynne occur in high-elevation sagebrush meadows in mountainous areas of the western U.S.A., and often are observed singing at temperatures as low −8 to −4 °C to attract sexuall...

The submandibular gland is a rich source of epidermal growth factor (EGF) in mice. The concentration of EGF in the gland of virgin female mice of C3H/HeN strain increased as much as 9-fold from the age of 30 to 52 weeks. During this period, the incidence of mammary tumor in virgin females increased markedly to a maximal level of 62.5% (n = 48) at 52 weeks of age. Removal of the submandibular gl...

Field trials were conducted in winter season in two sites located about 20km north east of Cairo; Gabal Asfar farm (fertile soil) and Berka site (virgin soil).The trials aimed to evaluate the impact of rapeseed irrigation methods with secondary treated wastewater on yield ,quality trace elements and heavy metal content. The results clearly showed that rapeseed crop was not suited to the virgin ...
