A subset (gamma(2)) of late herpes simplex virus 1 genes depends on viral DNA synthesis for its expression. For optimal expression, a small number of these genes, exemplified by U(S)11, also requires two viral proteins, the alpha protein infected cell protein (ICP) 22 and the protein kinase U(L)13. Earlier we showed that U(L)13 and ICP22 mediate the stabilization of cdc2 and the replacement of ...

Introduction: Internal exposure to radon gas progeny can lead to serious biologic damages to the lung tissue. The aim of this study was to evaluate the absorbed dose by lung tissue due to the exposure from short-lived radioactive products of radon (222Rn) decay using Monte Carlo simulation. Material and Methods: A lung equivalent p...

Several cytokines, especially granulocyte/macrophage colony-stimulating factor (GM-CSF) and tumor necrosis factor alpha (TNF-alpha), have been identified that foster the development of dendritic cells from blood and bone marrow precursors in suspension cultures. These precursors are reported to be infrequent or to yield small numbers of dendritic cells in colony-forming assays. Here we readily ...

background: in this study, measurement of indoor radon and its progeny levels was carried out in gas turbine power station in haryana ( india ), where natural gas is used as fuel. for comparison, the results of a study carried out in thermal power plant in haryana are also presented. radon being a ubiquitous air pollutant has global impact and its monitoring in the environment at work places is...

The long-standing problem related to prompt analyses in continuous air sampling or monitoring has been the well-known interference of the radon- and thoron-progeny co-deposited on the filtration media with any potential suspect radionuclides. The solutions to this problem have been quite diverse, and have included, for example, simple gross-alpha screening, the use of beta-to-alpha ratios, and/...

Zygotic transcription was analyzed in embryos of the glossiphoniid leech Helobdella triserialis by autoradiographic detection of tritiated uridine incorporated in the presence or absence of low concentrations of alpha-amanitin. RNA synthesis was first detected after the second cleavage and alpha-amanitin-sensitive RNA synthesis was first detected during the divisions yielding the embryonic stem...
