Changes in Availability and Affordability on the University Food Environment: The Potential Influence of the COVID-19 Pandemic.

Background: The COVID-19 pandemic has had an impact on the eating habits of the general population, among other reasons, because it has affected access to commercial establishments since some of them closed. This study aimed to describe potential changes that occurred between 2019 and 2022 in the availability and affordability of food and beverages in the food environment of a Brazilian public university.

Methods: Cross-sectional and descriptive study conducted at a public university located in Rio de Janeiro, Brazil.

Inflammatory Monocytes Increase Prior to Detectable HIV-1 Rebound Viremia.

The persistence of HIV-1 proviruses in latently infected cells allows viremia to resume upon treatment cessation. To characterize the resulting immune response, we compare plasma proteomics and single-cell transcriptomics of peripheral blood mononuclear cells (PBMCs) before, during, and after detectable plasma viremia. We observe unique transcriptional signatures prior to viral rebound including a significant increase in CD16 monocytes with increased anti-viral gene expression.

Is Platelet-rich Plasma Effective in Treating Achilles Tendinopathy? A Meta-analysis of Randomized Clinical Trials.

Background: Several meta-analyses have evaluated the use of platelet-rich plasma (PRP) in the treatment of Achilles tendinopathy. Although they generally did not find PRP to be effective, an updated meta-analysis containing all the available, high-quality randomized trial evidence that addresses the methodological shortcomings identified in earlier meta-analyses needs to be performed.

Question/purposes: This systematic review and meta-analysis aimed to evaluate the efficacy of PRP in improving (1) pain and function as assessed using the Victorian Institute of Sports Assessment-Achilles (VISA-A) score 3 months, 6 months, and 1 year after treatment and (2) VAS pain scores 3 months after treatment in patients with chronic Achilles tendinopathy.

Bio-based plasticizer Babassu oil for custom-made conductive additive-manufacturing filaments: towards 3D-printed electrodes applied to cocaine detection.

Babassu (Atallea sp.), a native palm tree from South America's Amazon produces bio-oil and biochar with significant potential for industrial applications. Babassu oil as a bio-based plasticizer is reported here for the first time to replace petrochemical alternatives in the production of conductive filaments for additive manufacturing purposes.

New insights into the putative role of leucine-rich repeat proteins of and their participation in host cell invasion: an analysis.

Pathogenic are spirochetes that cause leptospirosis, a worldwide zoonotic disease. Leptospirosis affects humans and animals, with approximately 1 million human infections and 60,000 deaths per year. The diversity of leptospiral strains and serovars allied to the fact that pathogenesis is not yet fully understood, make the development of an effective vaccine against leptospirosis a challenge.
