Assessment of COVID-19 incidence after performing pulmonary function tests during the pandemic: Findings from a real-life cohort.

Background: Pulmonary function testing (PFT) is paramount in assessing patients with respiratory symptoms and chronic cardiopulmonary diseases. Although seminal studies have demonstrated that PFT generates aerosols, this simple observation does not confirm the potential for enhanced pathogen transmission.

Objective: We aimed to describe the frequency of patients who developed suspected symptoms of COVID-19, prompting SARS-CoV-2 testing after undergoing PFT during the reopening of a laboratory amid the deceleration of the pandemic.

Oxidative stress induces plasma membrane phosphatidylserine externalization in canine erythrocytes in vitro, mitigated by thiol antioxidants.

Objective: To determine if oxidative stress induces phosphatidylserine (PS) externalization in canine erythrocytes and if exposure to antioxidants prevents such changes.

Methods: This was an in vitro, experimental study using 5 healthy, adult, purpose-bred research Beagles. Fresh EDTA-anticoagulated blood samples were collected from each dog, and erythrocytes were harvested.

Zinc-L-Selenomethionine Improves Growth and Hemato-Biochemical Parameters at Low but not at High Stocking Density for Nile Tilapia Males.

The study aimed to examine the interaction between diets supplemented with zinc-L-selenomethionine (ZnSeMet) and two stocking densities (SD) on Nile tilapia (Oreochromis niloticus) males. Four extruded diets were formulated: 0.0, 0.

Susceptibility of Tambaqui () to Nile Tilapia-Derived and .

Nile tilapia () and tambaqui () are the two most produced freshwater fishes in Brazil. This study investigated the potential pathogenicity of and , previously isolated from diseased Nile tilapia, to tambaqui. Experimental infection trials were conducted in juvenile tambaqui at a dose of approximately 10 CFU fish, assessing clinical signs, mortality, bacterial recovery, and histopathological changes.

Synergistic Pain-Reducing Effects of (Chronic and Chronic In) and Cannabidiol-Rich Extracts in Experimental Pain Models.

The present study aimed to evaluate the potential synergy between pharmaceutical formulations containing L. (granulated-CHR OR and injectable nanodispersion-CHR IN) in conjunction with a cannabidiol (CBD)-rich extract of L. (CSE) on experimental pain models in Wistar rats.
