Early Use of Liraglutide for the Treatment of Acute COVID-19 Infection: An Open-Label Single-Center Phase II Safety Study with Biomarker Profiling.

Background: Glucagon-like peptide-1 (GLP-1) agonists are an existing treatment option for patients with insulin-resistant states, which elicit further pleiotropic effects related to immune cell recruitment and vascular inflammation. GLP-1 agonists downregulate the cluster of differentiation 147 (CD147) receptor, one of several receptors for the SARS-CoV-2 spike protein that mediate viral infection of host cells.

Methods: We conducted an open-label prospective safety and tolerability study including biomarker responses of the GLP-1 agonist Liraglutide, administered for 5 days as an add-on therapy to the standard of care within 48 h of presentation in a cohort of 13 patients hospitalized with COVID-19 pneumonia.

Topical application of the ethanol extract and the hydroethanolic fraction of ripe Solanum lycocarpum A. St. Hil. fruit improves the healing of excisional wounds.

Purpose: To evaluate the effect of the topical application of the ethanol extract (EESL) and the hydroethanolic fraction (HFSL) of ripe Solanum lycocarpum fruit on the healing of experimentally-induced wounds in mice.

Methods: The EESL and HFSL obtained from ripe fruit of the species S. lycocarpum were obtained by percolation with ethanol.

Gait patterns in unstable older patients related with vestibular hypofunction. Preliminary results in assessment with time-frequency analysis.

Background: Gait instability and falls significantly impact life quality and morbi-mortality in elderly populations. Early diagnosis of gait disorders is one of the most effective approaches to minimize severe injuries.

Objective: To find a gait instability pattern in older adults through an image representation of data collected by a single sensor.

First record of microplastic contamination in adult endemic amazonian anuran species.

The microplastics (MPs), due to their high dispersion and bioaccumulation rates, have been identified in various animal groups, such as anuran amphibians during both larval and adult stages. However, current studies on adult anuran amphibians focus on assessing only one exposure route, the digestive system, while other routes remain underestimated. Therefore, this present study aimed to evaluate the degree of contamination in the digestive, respiratory, and integumentary systems, in situ, of two endemic Amazonian adult anuran species (Physalaemus ephippifer and Boana multifasciata).
