Arginine vasopressin (AVP) in the parvocellular neurons of the paraventricular nucleus (PVN) is known to play an important role in the hypothalamo-pituitary-adrenal axis. In the present study, we examined how cAMP and glucocorticoids regulate AVP gene expression in the parvocellular neurons of the PVN in rat hypothalamic organotypic cultures with in situ hybridization. AVP heteronuclear (hn) RN...

Hippocampal de novo mRNA and protein synthesis has been suggested to be critical for long-term spatial memory. However, its requirement in each memory process (i.e. encoding, consolidation and retrieval) and the differences in the roles of de novo mRNA and protein synthesis in different situations where spatial memory is tested have not been thoroughly investigated. To address these questions, ...

HLA class II antigens are central in initiating antigen-specific CD4+ T cell responses to HIV-1. Specific alleles have been associated with differential responses to HIV-1 infection and disease among adults. This study aims to determine the influence of HLA class II genes and their interactive effect on mother-child perinatal transmission in a drug naïve, Mother-Child HIV transmission cohort es...

There are four outcomes to feline coronavirus (FCoV) infection: the development of feline infectious peritonitis (FIP, which is immune-mediated), subclinical infection, development of healthy lifelong carriers and a small minority of cats who resist infection (Addie and Jarrett, Veterinary Record 148 (2001) 649). Examination of the FCoV genome has shown that the same strain of virus can produce...

We have shown previously that H11, a serine/threonine kinase, is up-regulated in a heart subjected to ischaemia/reperfusion. In the present study, we have characterized the cellular function of H11, using neonatal rat cardiac myocytes. Although transduction of adenovirus harbouring H11 at low doses increased the cell size, at higher doses it induced apoptosis in cardiac myocytes. Apoptosis was ...

A chromogenic and fluorogenic detection of aldehydes was achieved via analyte triggered opening of the deoxylactam of N-(rhodamine B)-deoxylactam-ethylenediamine (dRB-EDA). The utility of the sensor was demonstrated by fluorescent labeling of aldehyde-displaying sialoproteins on cell surfaces.

The aim of this document it to present an overview of some recent research activities on ultra–wideband (UWB) channel modeling. Compared to models introduced in DRB1.2, recent research was focused on more sophisticated tools to model UWB channels, like information theoretic arguments. Physical modeling of UWB channels was also investigated. Reference D.xx.xx Issue n.m 4 November 2006 507325 NEW...
