Immunogenetics of CD4 Lymphocyte Count Recovery during Antiretroviral Therapy: An AIDS Clinical Trials Group Study

During antiretroviral therapy, CD4 lymphocyte count increases are modest in some patients despite virologic control. We explored whether polymorphisms in genes important for T cell expansion, survival, and apoptosis are associated with the magnitude of CD4 lymphocyte count recovery during antiretroviral therapy. We studied treatment-naive individuals who achieved sustained control ...

Vascular involvement and cell damage in experimental AA and clinical β2‐microglobulin amyloidosis

Background. Amyloidosis is a highly prevalent disease characterized by the deposition of amyloid fibrils. Although several types of amyloidosis can be identified according to their protein constituents and suggest putative aetiological factors, the causes of amyloidosis remain unknown. Furthermore, the cellular participation and the ultrastructural particularities of amyloidosis ...

Factors Associated with Induced Abortion in Women Prostitutes in Asturias (Spain)

BackgroundThe aim is to investigate the factors that might be associated with the presence of induced abortion (IA) in women prostitutes in Asturias (Spain).Methodology/Principal FindingsCross-sectional descriptive study by self-completion questionnaire of 212 women prostitutes who attended the three Sexually Transmitted Disease Clinics in Asturias, between January–December 2003. ...

Risk Factors Influencing HIV Infection Incidence in a Rural African Population: A Nested Case-Control Study

BackgroundRisk factors influencing the incidence of human immunodeficiency virus (HIV) infection were investigated in a case-control study nested within a community-randomized trial of treatment of syndromic sexually transmitted infections (STIs) in rural Tanzania MethodsCase patients were persons who became HIV positive, and control subjects were randomly selected from among ...

Saccharomyces cerevisiae Fungemia: An Emerging Infectious Disease

Background Saccharomyces cerevisiae is well known in the baking and brewing industry and is also used as a probiotic in humans. However, it is a very uncommon cause of infection in humans.

Abnormalities in the functioning of adipocytes from R6/2 mice that are transgenic for the Huntington’s disease mutation

In an effort to characterize the basis of abnormalities in body weight regulation (i.e. wasting) in Huntington’s disease (HD), we examined adipocytes in a transgenic model of HD, the R6/2 mouse. These mice typically show severe wasting beginning at ∼12 weeks of age and die between 12 and 15 weeks. Despite an overall growth retardation compared with wild-type littermates, we ...

Isoniazid Hepatotoxicity among Drug Users: The Role of Hepatitis C

The incidence of and risk factors associated with hepatotoxicity in patients with chronic hepatitis have not been systematically studied. Therefore, we conducted a prospective study that included former drug users who were treated with isoniazid for latent tuberculosis infection. Of 415 patients, 20 (4.8%; 95% confidence interval [CI], 3–7.4) had hepatotoxicity diagnosed, and 6 ...

Evaluation of the Immunochromatographic Binax NOW Assay for Detection of Streptococcus pneumoniae Urinary Antigen in a Prospective Study of Community-Acquired Pneumonia in Spain

We evaluated the Binax NOW rapid immunochromatographic membrane test (ICT) for detection of Streptococcus pneumoniae urinary antigen in a population-based prospective study of adults with community-acquired pneumonia (CAP). ICT was performed with urine samples obtained from 452 (91.7%) of 493 patients enrolled. Pneumococcal antigen was detected in 19 (70.4%) of 27 patients with ...

Sperm motility index: a quick screening parameter from sperm quality analyser-IIB to rule out oligo- and asthenozoospermia in male fertility study

The aim of this study was to evaluate the sperm quality analyser (SQA)-IIB, a new automated sperm analyser, and to compare its results with those obtained with a method based on the World Health Organization recommendations. Eighty-nine unprocessed semen samples and 53 selected sperm suspensions were analysed. Concentration, motility and morphology were evaluated using the routine ...

Superinfection Following Smallpox Vaccination (Vaccinia), United States: Surveillance January 2003 through January 2004

Background. Superinfection is an adverse event following smallpox vaccination. The clinical presentation is similar to that of a large normal vaccine reaction or “robust take,” and the frequency is unknown. Methods. We retrospectively reviewed all reported severe local reactions consistent with superinfection among United States civilian smallpox vaccinees from January 2003 through ...

Genome-wide SNP assay reveals structural genomic variation, extended homozygosity and cell-line induced alterations in normal individuals

The recent hapmap effort has placed focus on the application of genome-wide SNP analysis to assess the contribution of genetic variability, particularly SNPs, to traits such as disease. Here, we describe the utility of genome-wide SNP analysis in the direct detection of extended homozygosity and structural genomic variation. We use this approach to assess the frequency of genomic ...

Broad-band and Hα surface photometry of the central regions of nearby active galaxies — I. Observations

Broad-band V, R and I and narrow-band Hα CCD surface photometry of a sample of 24 active and three normal nearby galaxies is presented, in order to study their morphological and structural properties. This first paper presents the observations, data reduction and processing techniques used; the main characteristics of the central regions of the sample galaxies are derived from ...

Diethanolamine Induces Hepatic Choline Deficiency in Mice

The purpose of the present experiments was to test the hypothesis that diethanolamine (DEA), an alkanolamine shown to be hepatocarcinogenic in mice, induces hepatic choline deficiency and to determine whether altered choline homeostasis was causally related to the carcinogenic outcome. To examine this hypothesis, the biochemical and histopathological changes in male B6C3F1 mice ...

V, R, I and Hα photometry of circumnuclear star-forming regions in four galaxies with different levels of nuclear activity

We present photometry, in the V, R and I continuum bands and in the Hα+[N ii] emission lines, for a sample of circumnuclear star-forming regions (CNSFR), located in four galaxies with different kinds of activity in their nuclei: NGC 7469 (Seyfert 1), NGC 1068 (Seyfert 2), NGC 7177 (LINER) and NGC 3310 (starburst). Hα luminosities for the CNSFR range from 0.02 to 7×1040 erg s−1 ...
