Polymorphisms Influence the Expression of the Fas and FasL Genes in COVID-19.

The apoptotic molecule Fas and its ligand FasL are involved in the process of T-lymphocyte death, which may lead to lymphopenia, a characteristic of severe coronavirus disease 2019 (COVID-19). In this study, we investigated the influence of polymorphisms in the and genes, and gene expression, and plasma cytokine levels on COVID-19 severity and long COVID occurrence. A total of 116 individuals with severe COVID-19 and 254 with the non-severe form of the disease were evaluated.

The bidirectional relationship between pain and tobacco use: Insights from the longitudinal Population Assessment of Tobacco and Health (PATH) study.

Background: Tobacco smoking remains the leading preventable cause of death, whereas chronic pain is the leading cause of disability. Chronic pain and tobacco smoking are closely interrelated. We investigated whether pain predicts daily cigarette smoking and if daily cigarette smoking predicts the development of pain.

Description of Colobomatus conodoni n. sp. (Cyclopoida: Philichthyidae), a New Parasitic Copepod from the Barred Grunt Conodon nobilis (Linnaeus, 1758) (Actinopterygii: Haemulidae) Off the Brazilian Coast.

Introduction: Copepods of the genus Colobomatus Hesse, 1873 are parasites associated with subcutaneous spaces of marine fish. To date, around 76 species of the genus have been described in marine ecosystems, but few species have been recorded in the South Atlantic Ocean.

Methods: One hundred and eight specimens of Co.

Distinct muscle growth and strength adaptations after preacher and incline biceps curl.

We compared performing preacher and incline biceps curls on changes in elbow flexors muscle size and strength. This was a between-group repeated measures randomized trial. Sixty-three young women performed preacher biceps curl (PC, n = 30) or incline biceps curl (IC, n = 33) for 8 weeks, twice a week.

Comprehensive molecular epidemiology of influenza viruses in Brazil: insights from a nationwide analysis.

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.
