Restriction of virus-specific cytotoxic T cell function by products of the major histocompatability complex (MHC), 1 a phenomenon first described in murine systems (1-3), has now been confirmed for the human T cell responses to antigens on cells infected by influenza (4, 5), Epstein-Barr (EB) (6, 7), and more recently, mumps (8), measles (9), and cytomegalo(10) 2 viruses. In each case the patte...

Objective: To examine the relationship between child maltreatment, clinically relevant adjustment problems, and dating violence in a community sample of adolescents. Method: Adolescents from 10 high schools (N = 1,419; response rate = 62%) in southwestern Ontario completed questionnaires that assessed past maltreatment, current adjustment, and dating violence. Logistic regression was used to co...

Activation of factor VIII (FVIII) by thrombin plays a fundamental role in the amplification of the coagulation cascade and takes place through specific proteolytic cleavages at Arg(372), Arg(740) and Arg(1689). Full FVIII activation requires cleavage at Arg(372), a process involving the alpha-thrombin exosite-II; referred to as heparin-binding site (HBS). The present study was aimed at investig...

Despite the interest of industry in nickel-based superalloys and its main features (high temperatures resistance, hardness, low thermal conductivity, among others), even today they are still materials that difficult to cut. Cutting tools withstand both high pressures highly localized at cutting area because elevated work hardening alloy problems for fluid access region, with consequent strong t...

Peanut is a crucial source of edible oil and nutrients. Five peanut genotypes' yield quality parameters were assessed to select superior genotypes. The experiment was conducted in Bangladesh Institute Nuclear Agriculture HQ's experimental field, Mymensingh-2202. Correlation study identified significant positive correlation pods plant-1, kernel weight shelling % with pod yield. Considering conte...
