Six rhesus macaques were adapted to morphine dependence by injecting three doses of morphine (5 mg/kg of body weight) for a total of 20 weeks. These animals along with six control macaques were infected intravenously with mixture of simian-human immunodeficiency virus KU-1B (SHIV(KU-1B)), SHIV(89.6P), and simian immunodeficiency virus 17E-Fr. Levels of(More)
HIV infection is increasing in minority groups, particularly in African American and Hispanic women. Although the incidence of HIV dementia has decreased since the advent of highly active antiretroviral treatment, prevalence of neurocognitive complications has increased as patients are now living longer. This study's purpose was to determine the(More)
While the mechanisms of cellular aging remain controversial, a leading hypothesis is that mitochondrial oxidative stress and mitochondrial dysfunction play a critical role in this process. Here, we provide data in aging rhesus macaques supporting the hypothesis that increased oxidative stress is a major characteristic of aging and may be responsible for the(More)
Historically, HIV vaccines specifically designed to raise cellular immunity resulted in protection from disease progression but not infection when tested in monkeys challenged with a single high virus exposure. An alternative approach, more analogous to human sexual exposures, is to repetitively challenge immunized monkeys with a much lower dose of virus(More)
Pink-to-red anogenital and facial sexual skin occurs in females of many primate species. Since female sexual skin color varies with reproductive state, it has long been assumed that color acts to stimulate male sexual interest. Although there is supportive evidence for this as regards anogenital skin, it is unclear whether this is also the case for facial(More)
Anti-HIV-active polysaccharides and polyphenols were isolated from the brown seaweed Fucus vesiculosus by hot H2O extraction of both the intact and the homogenized algae. This was followed by XAD2 chromatography and by sequential precipitation of the non-adsorbed compounds with glacial HOAc and thereafter with EtOH. The precipitate was solubilized, dialyzed(More)
SIVsm chronically infected cultures were obtained after infection of CEMX174 cells with either SIVsmH3 or SIVsmE660. These phenotypically CD4 cells, formed syncytia but only when cocultivated with CD4+ cells. Single cell clones were derived from these cultures and examined for the production of virus-specific proteins. The majority of the clones expressed(More)
Macaques are the only animal model used to test dengue virus (DENV) vaccine candidates. Nevertheless, the pathogenesis of DENV in macaques is not well understood. In this work, by using Affymetrix oligonucleotide microarrays, we studied the broad transcriptional modifications and cytokine expression profile after infecting rhesus macaques with DENV serotype(More)
Incidence of HIV and of several other sexually transmitted diseases (STDs) was determined in 171 female prostitutes from 3 sites in San Juan, Puerto Rico. The sites were selected by high incidence of penicillinase-producing N. gonorrhoeae in clients of prostitutes. These women came from about a dozen different countries, mostly Latin American. 14%(More)
