Cumulative Impact Loading and Cartilage Synthesis Biomarkers May Be Associated With Injury Risk in Female Collegiate Basketball Players.

Purpose: To evaluate whether cumulative impact load and serum biomarkers are related to lower-extremity injury and to determine any impact load and cartilage biomarker relationships in collegiate female basketball athletes.

Methods: This was a prospective longitudinal study evaluating lower-extremity impact load, serum cartilage biomarkers, and injury incidence over the course of a single collegiate women's basketball season. Data were collected from August 2022 to April 2023; no other follow-up after the cessation of the season was conducted in this cohort.

Role of the stratosphere in the global mercury cycle.

Mercury (Hg) is a global pollutant with substantial risks to human and ecosystem health. By upward transport in tropical regions, mercury enters into the stratosphere, but the contribution of the stratosphere to global mercury dispersion and deposition remains unknown. We find that between 5 and 50% (passing through the 400-kelvin isentropic surface and tropopause, respectively) of the mercury mass deposited on Earth's surface is chemically processed in the lower stratosphere.

Rapid NO Formation from N on Water Droplet Surfaces.

Nitrogen (N) has long been considered as stable atmospheric reservoir for N element and has a persistence time of hundreds of years. This study reveals that oxygen (O) at typical tropospheric concentrations can rapidly activate N, leading to substantial production of nitrous oxide (NO), the third most impactful greenhouse gas, at rates approaching 2.83±0.

Position statement of the Spanish Working Group on Crohn's Disease and Ulcerative Colitis on the use of Telemedicine in Inflammatory Bowel Disease.

Inflammatory Bowel Disease (IBD) is a chronic digestive condition that requires continuous monitoring by healthcare professionals to determine appropriate therapy and manage short- and long-term complications. Telemedicine has become an essential approach for managing chronic conditions such as IBD, improving care accessibility and continuity, decreasing hospitalization rates, and optimizing patient follow-up. It enables rapid treatment adjustments and encourages patient self-management.

Heterogenous Chemistry of IO as a Critical Step in Iodine Cycling.

Global iodine emissions have been increasing rapidly in recent decades, further influencing the Earth's climate and human health. However, our incomplete understanding of the iodine chemical cycle, especially the fate of higher iodine oxides, introduces substantial uncertainties into atmospheric modeling. IO was previously deemed a "dead end" in iodine chemistry; however, we provide atomic-level evidence that IO can undergo rapid air-water or air-ice interfacial reactions within several picoseconds; these reactions are facilitated by prevalent chemicals on seawater such as amines and halide ions, to produce photolabile reactive iodine species such as HOI and IX (X = I, Br, and Cl).
