Effect of temperature on circadian clock functioning of trees in the context of global warming.

Plant survival in a warmer world requires the timely adjustment of biological processes to cyclical changes in the new environment. Circadian oscillators have been proposed to contribute to thermal adaptation and plasticity. However, the influence of temperature on circadian clock performance and its impact on plant behaviour in natural ecosystems are not well-understood.

A new species of Asplenium L. (Aspleniaceae) is described and illustrated. Asplenium sylvaticum is endemic of the Yungas and Paraná biogeographic provinces in the Southern Cone.

The Critical Role of Health Educators: Findings from the 2021 Public Health Workforce Interests and Needs Survey (PH WINS).

Objective: This analysis of governmental health educators from the 2021 Public Health Workforce Interest and Needs Survey (PH WINS) examines demographic and workplace characteristics, COVID-19 pandemic activities and beliefs, job satisfaction, training needs, mental health, and engagement in health equity.

Setting And Participants: Participants were public health staff in public health agencies who completed the 2021 PH WINS.

Design And Main Outcome Measures: Chi-square and means tests were used to compare job satisfaction, mental health status, training needs, and health equity concepts between health educators and other disciplines in the governmental public health workforce.

Glutamine promotes human CD8 T cells and counteracts imiquimod-induced T cell hyporesponsiveness.

T cells protect tissues from cancer. Although investigations in mice showed that amino acids (AA) critically regulate T cell immunity, this remains poorly understood in humans. Here, we describe the AA composition of interstitial fluids in keratinocyte-derived skin cancers (KDSCs) and study the effect of AA on T cells using models of primary human cells and tissues.
