Trait sensitivity to stress and cognitive bias processes in fish: A brief overview.

Like other animals, fish have unique personalities that can affect their cognition and responses to environmental stressors. These individual personality differences are often referred to as "behavioural syndromes" or "stress coping styles" and can include personality traits such as boldness, shyness, aggression, exploration, locomotor activity, and sociability. For example, bolder or proactive fish may be more likely to take risks and present lower hypothalamo-pituitary-adrenal/interrenal axis reactivity as compared to shy or reactive individuals.

Using Pre-Exercise Photobiomodulation Therapy Combining Super-Pulsed Lasers and Light-Emitting Diodes to Improve Performance in Progressive Cardiopulmonary Exercise Tests.

Context: Skeletal muscle fatigue and exercise performance are novel areas of research and clinical application in the photobiomodulation field, and positive outcomes have been reported in several studies; however, the optimal measures have not been fully established.

Objective: To assess the acute effect of photobiomodulation therapy (PBMT) combining superpulsed lasers (low-level laser therapy) and light-emitting diodes (LEDs) on muscle performance during a progressive cardiopulmonary treadmill exercise test.

Design: Crossover study.

Epidemiological aspects of Toxoplasma gondii infection in riverside communities in the Southern Brazilian Amazon.

Introduction: Toxoplasma gondii infection is widely prevalent in humans and other animals worldwide. Information on the prevalence of T. gondii infection is scarce in some regions of Brazil, including riverside communities along the Amazon River basin.

Use of ivermectin in the treatment of orbital myiasis caused by Cochliomyia hominivorax.

Orbital myiasis cases by dipterous fly larvae are rarely reported. A case of massive orbital myiasis caused by Cochliomyia hominivorax resulting in complete loss of the globe is described. Oral ivermectin was used successfully to eliminate the larvae prior to enucleation, making the mechanical removal of larvae an unnecessary procedure.
