Distinct Pharmacodynamic Activity of Rilpivirine in Ectocervical and Colonic Explant Tissue.

A long-acting injectable form of rilpivirine (RPV) is being evaluated in clinical trials for the prevention of HIV infection. Preclinical testing was undertaken to define RPV pharmacokinetic (PK) and pharmacodynamic (PD) activities in ectocervical and colonic tissue treated in vitro Tenfold dilutions of RPV were added to the basolateral medium of polarized ectocervical and colonic explant tissues. To half the explants, HIV-1BaL was applied to the apical tissue surface.

Identification of novel microbes associated with pelvic inflammatory disease and infertility.

Objectives: As pelvic inflammatory disease (PID) aetiology is not completely understood, we examined the relationship between select novel bacteria, PID and long-term sequelae.

Methods: Fastidious bacterial vaginosis (BV)-associated bacteria (Sneathia (Leptotrichia) sanguinegens, Sneathia amnionii, Atopobium vaginae and BV-associated bacteria 1 (BVAB1)), as well as Ureaplasma urealyticum and Ureaplasma parvum were identified in cervical and endometrial specimens using organism-specific PCR assays among 545 women enrolled in the PID Evaluation and Clinical Health study. Risk ratios and 95% CIs were constructed to determine associations between bacteria, histologically confirmed endometritis, recurrent PID and infertility, adjusting for age, race, gonorrhoea and chlamydia.

Broadly Neutralizing Anti-HIV Antibodies Prevent HIV Infection of Mucosal Tissue Ex Vivo.

Broadly neutralizing monoclonal antibodies (nAbs) specific for HIV are being investigated for use in HIV prevention. Due to their ability to inhibit HIV attachment to and entry into target cells, nAbs may be suitable for use as topical HIV microbicides. As such, they would present an alternative intervention for individuals who may not benefit from using antiretroviral-based products for HIV prevention.

The assembly of miRNA-mRNA-protein regulatory networks using high-throughput expression data.

Motivation: Inference of gene regulatory networks from high throughput measurement of gene and protein expression is particularly attractive because it allows the simultaneous discovery of interactive molecular signals for numerous genes and proteins at a relatively low cost.

Results: We developed two score-based local causal learning algorithms that utilized the Markov blanket search to identify direct regulators of target mRNAs and proteins. These two algorithms were specifically designed for integrated high throughput RNA and protein data.

Women's perspectives on the context of violence and role of police in their intimate partner violence arrest experiences.

Intimate partner violence (IPV) accounts for up to 50% of all calls to police. In an effort to standardize arrest criteria, mandatory arrest laws were established. It is unclear whether subsequent increased rates of female arrest are due to greater recognition of female IPV perpetrators or of women acting in self-defense.

Follistatin-like 3 across gestation in preeclampsia and uncomplicated pregnancies among lean and obese women.

The purpose of this study was to examine circulating maternal follistatin-like 3 (FSTL-3) by gestational age and obesity in pregnancy and preeclampsia. FSTL-3 was quantified in maternal plasma collected in each trimester from prepregnancy body mass index-determined groups: 15 lean and 24 obese controls and 20 obese women who developed preeclampsia. Repeated measures mixed models and logistic regression were conducted (P ≤ .
