Preference for HIV Pre-exposure Prophylaxis Access Among Men who Have Sex With Men in China: A Discrete Choice Experiment.

Background: HIV pre-exposure prophylaxis (PrEP) is highly effective but not widely used by men who have sex with men (MSM; 27%) in China.

Methods: In June 2023, an online cross-sectional survey with a discrete choice experiment (DCE) was distributed to PrEP-eligible MSM in China who were at least 18 years old. The DCE explored attributes of PrEP modality (daily pill, on-demand pill, injections, implants), clinical care model (same-day, 2-visit, telehealth prescription), medication pickup (clinic, community health center, pharmacy, MSM-focused community-based organization, home delivery), enhanced support (self-management, smartphone app, text reminder, anonymous peer support group), and cost.

Exploring PrEP Motivation as a Modifiable Target for HIV Prevention Uptake for Cisgender Women in Atlanta, Georgia.

Background: Pre-exposure prophylaxis for HIV prevention (PrEP) prescriptions in the U.S. have increased, yet only 15% of individuals assigned female at birth who could benefit from PrEP had received prescriptions as of 2022, with marked racial disparities.

Structured lipids from fish viscera and coconut oils improve weight gain and intestinal morphology of piglets at nursery phase.

Five metabolism assays were performed to determine the metabolizable energy (ME) content of soybean oil, coconut oil, fish viscera oil, physical mixture of coconut oil and fish viscera oil (3:2, in kg: kg) and structured lipid prepared from interesterification of fish viscera oil and coconut oil (3: 2, in kg: kg), and one assay to evaluate the effects of including these lipid sources in piglet diets on performance, digestibility of diets, incidence of diarrhea and intestinal morphometry at nursery phase. Soybean, coconut, fish viscera, physical mixture and structured lipid oils showed ME values of 8239, 8199, 8839, 8268 and 8523 kcal/kg DM respectively. In the performance trial, a total of 90 piglets with 23 days of age were distributed among 5 diets, differing in the lipid source used (soybean oil, coconut oil, fish viscera oil, physical mixture or structured lipid).

Asphaltenes biodegradation from heavy crude oils by the yeast Yarrowia lipolytica.

Heavy crude oil reserves are characterized by their high viscosity and density, largely due to significant quantities of asphaltenes. The removal of asphaltene precipitates from oil industry installations is crucial, as they can contaminate catalysts and obstruct pipelines. Therefore, this study aimed to bio-transform heavy oil asphaltenes into smaller molecules using the yeast Yarrowia lipolytica, known for its ability to efficiently degrade hydrophobic substrates.
