An assay has been developed and measurements of aryl hydrocarbon [benzo(a)pyrene] hydroxylase have been made in peripheral blood monocytes from a human population. Treatment with benz(a)anthracene in cell culture increased aryl hydrocarbon hydroxylase activity from 6.5 to 37-fold in monocytes from each of 25 apparently healthy donors. A weak correlation (r = 0.38) was observed between the induc...

Despite the ubiquity and rich features of current mobile phones, mobile games have failed to reach even the lowest estimates of expected revenues. This is unfortunate as mobile phones offer unique possibilities for creating games aimed at attracting demographics not currently catered for by the traditional console market. As a result, there has been a growing call for greater innovation within ...

A modified Ebers-Moll transistor model for RF-interference analysis " in IEEE Trans.

Accurate test effectiveness estimation for analogue and mixed-signal Systems on a Chip (SoCs) is currently prohibitive in the design environment. One of the factors that sky rockets fault simulation costs is the number of structural faults which need to be simulated at circuit-level. The purpose of this paper is to propose a novel fault list compression technique by defining a stratified fault ...

This investigation examined the effects of mediators derived form activated spleen cells on macrophage Ia-antigen expression and function. Incubation of adherent thioglycollate-induced murine peritoneal macrophages(> 90% Ia-) with concanavalin A (Con A)-stimulated spleen cell supernate (Con A sup) resulted in a dose-dependent increase in the percentage of Ia-containing (Ia+) phagocytic cells, a...

Several IP components have been developed and are presented here including analog, digital, mixed-signal, and MEMS circuitry. These components have been incorporated into a recently founded research IP repository, UMIPS, for design reuse. A complete microsystem has since been developed from this repository using an IPbased development framework and platform design approach. Here a discussion is...

T lymphocytes that are activated in the autologous mixed lymphocyte reaction (MLR) have suppressor activity. Concanavalin A (Con A) augments the suppressor activity generated in cultures containing both T and non-T lymphocytes and can induce suppressor activity in T-lymphocyte preparations that contain too few (10%) non-T cells to generate a significant autologous MLR. However, when such T-lymp...

Hepatitis A infection is a common disease in tropical countries, including Thailand. Hepatitis A vaccination of children and adolescents has been recommended by many countries. We performed a cost-benefit analysis in order to determine the best strategy for Thailand. Three strategies were tested: a) no intervention; b) vaccination without screening; c) vaccination after screening. A review of t...

In an attempt to modulate the recognition processes that occur on lymphocyte membranes in mixed lymphocyte culture, responding cortisone resistant thymocytes or stimulating spleen cells (treated with mitomycin C) were pretreated with native concanavalin A (N-Con A) or succinyl-Con A (S-Con A). Highly significant cell proliferation was observed in syngeneic combinations when either the respondin...
