Over the last decades, the human species has seen an increase in the incidence of pathologies linked to the genitourinary tract. Observations in animals have allowed us to link these increases, at least in part, to changes in the environment and, in particular, to an increasing presence of endocrine disruptors. These can be physical agents, such as light or heat; natural products, such as phytoestrogens; or chemicals produced by humans.

Introduction: Granulocyte concentrates (GC) are leukocyte preparations enriched in neutrophils that can potentially save neutropenic patients from life-threatening, antimicrobial-resistant infections. The main challenge of GC transfusions is preserving the viability and antimicrobial activity of neutrophils beyond 24 h to reduce the logistical burden on collection centers and increase the availability of this cell therapy. Thus, the aim of this study was to explore extending the ex vivo viability and antimicrobial activity of GC neutrophils up to 72 h with a unique combination of the clinically-approved additives Plasma-Lyte, SAGM, AS-3 and Alburex.

Can J Cardiol

December 2024

Institut Universitaire de Cardiologie et de Pneumologie de Québec- Université Laval, Quebec, Canada; Faculty of Medicine, Laval University, Quebec, Canada. Electronic address:

This review looks into sedentary behavior (SB) beyond its simplistic definition of "sitting" while also including sedentary activities. It explores the definition, physiological characteristics, prevalence, and guidelines of SB, contrasting it with physical activity (PA). The discussion encompasses: 1) the association between SB and mortality, with a specific focus on cardiovascular (CV) outcomes; 2) biological mechanisms linking SB to CV health, differentiating between the impacts of acute and chronic sitting additionally, 3) sex and gender differences in SB and, 4) SB as an independent CV risk factor are explored.
