BACKGROUND AND METHODS The extent to which renal allotransplantation - as compared with long-term dialysis - improves survival among patients with end-stage renal disease is controversial, because those selected for transplantation may have a lower base-line risk of death. In an attempt to distinguish the effects of patient selection from those of(More)
Evidence suggests that the New World was colonized only 11,000-40,000 years ago by Palaeo-Indians. The descendants of these Palaeo-Indians therefore provide a unique opportunity to study the effects of selection on major histocompatibility complex class I genes over a short period. Here we analyse the class I alleles of the Waorani of South America and the(More)
This study creates a compendium of gene expression in normal human tissues suitable as a reference for defining basic organ systems biology. Using oligonucleotide microarrays, we analyze 59 samples representing 19 distinct tissue types. Of approximately 7,000 genes analyzed, 451 genes are expressed in all tissue types and designated as housekeeping genes.(More)
Multiple sclerosis is thought to be an autoimmune disease of the central nervous system mediated by T cells specific for a myelin antigen. Myelin basic protein has been studied as a potential autoantigen in the disease because of its role as an encephalitogen in experimental autoimmune encephalomyelitis and post-viral encephalomyelitis and because of the(More)
BACKGROUND There is a high prevalence of liver disease among the recipients of organs from donors with antibodies to hepatitis C virus (HCV). We undertook a study to determine the frequency of persistent HCV infection, as indicated by the presence of HCV RNA, among both cadaveric organ donors positive for antibodies to HCV (anti-HCV) and the recipients or(More)
We undertook a prospective randomized trial to examine whether an intravenous cytomegalovirus (CMV) immune globulin would prevent primary CMV disease in renal-transplant recipients. Fifty-nine CMV-seronegative patients who received kidneys from donors who had antibodies against CMV were assigned to receive either intravenous CMV immune globulin or no(More)
The findings cited in this report suggest that renal allograft survival might be improved by matching nephron supply to recipient needs (analogous to prescription dialysis based on Kt/V). Methods for assessing functional graft capacity (ie, nephron number, filtration, or total microvascular surface area) are needed. Graft weights might serve as a useful(More)
The renin-angiotensin system (RAS) plays an important role in the regulation of inflammation and in the progression of chronic kidney disease. Accumulation of inflammatory cells into the renal parenchyma has been a hallmark of chronic kidney disease; however, little is known concerning the presence and the function of RAS elements in T and natural killer(More)
OBJECTIVE To study Class I soluble HLA in black patients with rheumatoid arthritis (RA) and their families, and to compare the findings to a group of healthy families of the same racial background. METHODS ELISA was developed measure soluble HLA Class I (sHLAI) in the serum of 25 patients with RA. Family studies were performed in seven patients with RA(More)
