OBJECTIVES HIV-infected controllers have provided novel insights into mechanisms of viral control. We investigated the degree to which HIV DNA and RNA are present in gut-associated lymphoid tissue (GALT) of controllers. DESIGN Cross-sectional cohort study. METHODS Colorectal biopsy pieces were obtained from five untreated noncontrollers, five(More)
Errorless learning (EL) procedures have been shown to be effective in teaching new information and new procedures to individuals with severe memory impairment. The published studies have been based on comparatively short-term interventions delivered to individuals with relatively circumscribed impairments. In this single case study, we explore the(More)
UNLABELLED The anti-inflammatory agent, mesalamine (5-aminosalicylic acid) has been shown to decrease mucosal inflammation in ulcerative colitis. The effect of mesalamine in HIV-infected individuals, who exhibit abnormal mucosal immune activation and microbial translocation (MT), has not been established in a placebo-controlled trial. We randomized 33(More)
Gap junctions and purinergic P2 receptors (P2Rs) can be regarded as belonging to a common functional unit, given that they are involved in the transmission of calcium signals between cells. We have previously shown that deletion of the Gja1 gene alters expression levels of numerous genes encoding proteins with diverse functions, including purinergic(More)
