BACKGROUND AND PURPOSE Circulating endothelial progenitor cells (EPCs) play an important role in repair of injured vascular endothelium and neovascularization. The present study was designed to determine the effect of EPCs transplantation on the regeneration of endothelium and recovery of endothelial function in denuded carotid arteries. METHODS Isolated(More)
Chicken infectious anemia virus (CIAV) is a unique infectious agent with an amino acid composition that has been found to be remarkably conserved even in isolates from different parts of the world. We have characterized field isolates of CIAV which vary significantly in terms of their abilities to replicate in culture, demonstrating a biological difference(More)
Genes from the SNF2 family play important roles in transcriptional regulation, maintenance of chromosome integrity and DNA repair. This study describes the molecular cloning and characterization of cereal genes from this family. The predicted proteins exhibit a novel C-terminal domain that defines a new subfamily designated SNF2P that includes human and(More)
Apoptosis of CD4(+) T lymphocytes, induced by contact between human immunodeficiency virus type 1 (HIV-1) envelope glycoprotein (gp120) and its receptors, could contribute to the cell depletion observed in HIV-infected individuals. CXCR4 appears to play an important role in gp120-induced cell death, but the mechanisms involved in this apoptotic process(More)
INTRODUCTION The earliest lesion in the kidneys of idiopathic calcium oxalate stone formers is deposition of calcium phosphate in the interstitium, termed a Randall's plaque. Yet the cellular and molecular factors leading to their formation are unknown. METHODS The influence of urinary proteins on adhesion of preformed calcium oxalate crystals to rat(More)
The 'shock and kill' approach to cure human immunodeficiency virus (HIV) includes transcriptional induction of latent HIV-1 proviruses using latency-reversing agents (LRAs) with targeted immunotherapy to purge infected cells. The administration of LRAs (panobinostat or vorinostat) to HIV-1-infected individuals on antiretroviral therapy induces a significant(More)
BACKGROUND Coronary artery calcium, a radiographic marker for atherosclerosis and a predictor of coronary heart disease (CHD), is less extensive in women than in men of the same age. The role of estrogen in the pathogenesis of coronary artery calcification is unknown. We examined the association of estrogen status with extent of calcification and(More)
Sequential plasma samples obtained from 16 individuals who seroconverted were tested for the presence of antibody to human immunodeficiency virus type 1 (HIV-1) by an antigen conjugate enzyme immunoassay (EIA) and a conventional antibody conjugate assay. In 11 of these individuals, the antigen conjugate assay detected antibody to HIV-1 2 to 11 days (mean,(More)
BACKGROUND Controversy exists over the association of estrogen and cardiovascular disease. Estrogen receptors (ERs) alpha and beta are expressed in the endothelial cells and vascular smooth muscle cells (VSMCs) of many arteries, but the relative importance of ERalpha or ERbeta in mediating the vascular response to estrogens is not well defined, particularly(More)
The target cells of most steroid hormones contain prominent structures termed nuclear bodies (NB). Estrogen (ES) responsive tissues have very distinctive NB, whose development has been associated with both the level of ES receptors and their retention times in nuclei. It has been suggested that these NB may be large-scale ES binding centers at(More)
