Influenza A and B viruses represent significant global health threats, contributing substantially to morbidity and mortality rates. However, a comprehensive understanding of the molecular epidemiology of these viruses in Brazil, a continental-size country and a crucial hub for the entry, circulation, and dissemination of influenza viruses within South America, still needs to be improved. This study addresses this gap by consolidating data and samples across all Brazilian macroregions, as part of the Center for Viral Surveillance and Serological Assessment project, together with an extensive number of other Brazilian sequences provided by a public database during the epidemic seasons spanning 2021-23.

Objectives: This study evaluated the effectiveness of initiating novel therapies during hospitalization or vulnerable phase for WHF patients to reduce rehospitalization risks and determine the optimal treatment sequence.
Background: Currently, great debate exists over the proposed superiority of some resistance exercises to induce muscular adaptations. For example, some argue that unilateral exercise (meaning one limb at a time) is superior to bilateral exercises (meaning both limbs). Of note, an evidence-based answer to this question is yet to be determined, particularly regarding muscle hypertrophy.

Greenhouse and field experiments were conducted to investigate the effects of exogenous applications of the phytohormones gibberellic acid (GA3) and abscisic acid (ABA) on waterhemp (Amaranthus tuberculatus [Moq.]) emergence.
