Helminth extracellular vesicles co-opt host monocytes to drive T cell anergy.

Parasitic helminths secrete extracellular vesicles (EVs) into their host tissues to modulate immune responses, but the underlying mechanisms are poorly understood. We demonstrate that Ascaris EVs are efficiently internalised by monocytes in human peripheral blood mononuclear cells and increase the percentage of classical monocytes. Furthermore, EV treatment of monocytes induced a novel anti-inflammatory phenotype characterised by CD14, CD16, CC chemokine receptor 2 (CCR2) and programmed death-ligand 1 (PD-L1) cells.

Long-term impact of congenital Zika virus infection on the rat hippocampus: Neuroinflammatory, glial alterations and sex-specific effects.

Congenital Zika Syndrome (CZS) is a condition that arises when a neonate presents with abnormalities resulting from Zika virus infection during gestation. While microcephaly is a prominent feature of the syndrome, other forms of brain damage are also observed, often accompanied by significant neurological complications. It is therefore essential to investigate the long-term effects of CZS, with special attention to sex differences, particularly concerning hippocampal function, given its vulnerability to viral infections.

Thriving Through Adaptation: Adaptive Sports after Spinal Cord Injury.

This article focuses on identifying how health care providers can support a person with spinal cord injury to pursue and maintain involvement in adaptive sports. Benefits and barriers of sport participation, equipment considerations, and recommendations on how to determine sport appropriateness for a person with spinal cord injury will be provided. The authors emphasize through appropriate medical management and consideration of level of disability, functional performance, psychological readiness, and individual preference, a health care provider can play a valuable role in connecting individuals with spinal cord injury to adaptive sports and recreation.

Importance of habit and environmental characteristics in shaping patterns of richness and range size of ferns and lycophytes in the Atlantic Forest.

Premise: Ferns and lycophytes, the two spore-bearing lineages of vascular plants, share a unique life cycle, and because of several morpho-ecophysiological similarities, are usually investigated as a unit, but they may have distinct ecological and environmental responses. Understanding the diversity and distribution patterns of ferns and lycophytes separately is essential for designing effective conservation strategies.

Methods: We assessed species richness and range sizes using range-diversity analyses and investigated environmental (climatic, edaphic) and ecological (endemism, habit diversity, specialization) predictors of these range and richness metrics using generalized linear models.

Air temperature and humidity impact out-of-hospital-cardiac-arrests in Germany: A 10-year cohort study from the German Resuscitation Registry.

Objectives: This study examines the impact of temperature variations on out-of-hospital-cardiac-arrests in Germany over a decade (2010-2019). Out-of-hospital-cardiac-arrests affects 164 per 100,000 inhabitants annually in Germany, 11% survive to hospital discharge. The following study investigates days with the following characteristics: summer days, frost days, and high humidity days.
