High-throughput microarray analysis is an efficient means of obtaining a genome-wide view of transcript profiles across physiological states. However, quantitative PCR (qPCR) remains the chosen method for high-precision mRNA abundance analysis. Essential for reliability of qPCR data is normalization using appropriate internal control genes (ICG), which is(More)
Coma, tetany, dehydration, hypotension, tachycardia, and hyperpyrexia developed in a 2 1/2-year-old girl following two hypertonic phosphate pediatric enemas. She had marked hyperphosphatemia, hypocalcemia, hypernatremia, and acidosis. Hypocalcemia due to hyperphosphatemia can explain all of these findings. Calculations indicate that about one third of the(More)
BACKGROUND A causal association links high-risk human papillomavirus (HR-HPV) and cervical cancer, which is a major public health problem. The objective of the present study was to investigate the association between male circumcision (MC) and the prevalence of HR-HPV among young men. METHODS We used data from a MC trial conducted in Orange Farm, South(More)
OBJECTIVE Little is known about the interaction between human papillomavirus (HPV) and HIV. This study aimed to explore the association of oncogenic (high risk) and nononcogenic (low risk) HPV with HIV incidence. METHODS We used 1683 urethral swabs collected at the last follow-up visit of a male circumcision trial conducted in Orange Farm (South Africa).(More)
BACKGROUND The optimum collection procedure for the evaluation of HIV-1 burden in ulcer secretions has not been well defined. OBJECTIVES The objective of this study was to compare ulcer swabs and ulcer lavages for the detection and quantitation of HIV-1 RNA in genital ulcers. STUDY DESIGN A convenience sample of the first 84 HIV-positive participants in(More)
BACKGROUND Low-Risk Human Papillomavirus (LR-HPV) genotypes 6 and 11 cause genital warts. This study investigated the association of LR-HPV infection with male circumcision (MC). METHODS We used data from the South African MC trial conducted among young men. Urethral swabs, collected among intervention (circumcised) and control (uncircumcised) groups,(More)
OBJECTIVE In 2012, 7 years after the introduction of antiretroviral treatment (ART) in the South African township of Orange Farm, we measured the proportion of HIV-positive people who were virally suppressed, especially among high-risk groups (women 18-29 years and men 25-34 years). DESIGN A community-based cross-sectional representative survey was(More)
Recent evidence suggests that the cirrhosis of alpha-1-antitrypsin deficiency is not invariably fatal as it was previously thought. Portal hypertension is often the major determinant of survival. The few reports of porta-systemic venous anastomosis in this disorder have shown poor results or uncertain outcome. Thus, doubts exist as to whether porta-systemic(More)
