Glutathione is a ubiquitous antioxidant with critical roles in xenobiotic clearance and aerobic metabolism. Reduced glutathione (GSH) is converted to its oxidized counterpart, GSSG, in the process of neutralizing free radicals and maintaining biochemical homeostasis. An imbalance between free radical generation and antioxidant protection leads to oxidative stress and diminished GSH concentrations. Polymorphisms in GSH synthesi...

Muscle fascicle length is a key determinant of sprint performance, with lengthening adaptations observed following eccentric strength training or combined sprint and resistance interventions. However, whether sprint-focused training can induce meaningful architectural adaptations, independent of concurrent sport-related training, remains unclear. Fourteen participants (10 female, 4 male; age 21.6 ± 3.3 years; body mass 68.0 ±...

While genetic testing (GT) has become more available over the past decade, it is unclear whether public awareness and use have increased proportionally. We aimed to evaluate national trends in GT awareness and usage. We performed a cross-sectional analysis of nationally representative data from the National Cancer Institute’s Health Information National Trends Survey (HINTS). We analyzed survey responses from HINTS 4 Cycle 1–4...

Background and aims Biological nitrogen fixation (BNF) supplies much of soybean ( Glycine max (L.) Merr.) nitrogen (N) demand, but reported fixation rates vary widely, leading to uncertainty in the soybean N cycle. We quantified whole-plant soybean BNF and N allocation using long-term 15 N labeling to assess whether BNF can offset grain N removal in a high-yielding system, and to quantify root contributions to fixed N. Methods...

Blacktip sharks ( Carcharhinus limbatus ) are a circumglobal species that rely on nearshore nursery habitats during their early years. Movement patterns and habitat use of blacktip sharks in the Hawaiian Islands is poorly understood, and no nursery habitats have been discovered within Hawai’i. For this study, juvenile blacktip sharks (n = 29) were caught and tagged in Hilo Bay, Hawai’i, USA with acoustic transmitters. Tracking...
