Functional movement screen scores and injury prevalence among collegiate basketball players: a cross-sectional analysis

<title>Abstract</title> Background The Functional Movement Screen (FMS) is widely used to evaluate movement quality and injury risk in athletes, yet evidence regarding its applicability in non-Western collegiate basketball contexts remains limited. This study examined the associa...

Extraction and optimization of chitosan yield and deacetylation quality from mushroom mycelium waste

The growing mushroom industry generates substantial quantities of residual mycelial biomass, much of which is discarded despite its potential as a source of value-added biopolymers. This study investigated the extraction of fungal chitosan from Pleurotus ostreatus mycelium waste...

Longitudinal Associations Among Maternal Health Literacy, Psychological Empowerment and Health‐Promoting Behaviours in Rural Pregnant Women: A Cross‐Lagged Panel Study

AIMS: To examine longitudinal associations among maternal health literacy, psychological empowerment and health-promoting behaviours across pregnancy among rural pregnant women. DESIGN: Prospective cohort study. METHODS: Between 1 May 2023 and 15 January 2024, 694 rural pregnant...

Exploring the pedagogical landscape of mobile social network-supported microlearning in higher education: a community of inquiry perspective

Purpose This scoping review maps mobile social network–supported microlearning (MSNSM) in higher education, identifying research trends and applications and how MSNSM enhances cognitive, social and teaching presence within the community of inquiry (CoI) framework. Design/methodol...

Task-oriented circuit training to improve adaptive walking and cognitive-motor function after stroke: a clinical review

Abstract Background The evaluation of ambulation recovery after stroke commonly involves the use of linear outcomes such as walking speed and endurance. Task-oriented circuit training (TOCT) is commonly used in stroke rehabilitation to improve walking performance, but most existi...

Characterisation of monocyte migration potential in response to stimuli from human arthroplasty revision xenograft transplanted in a NOD-SCID mouse model

Monocyte migration into periprosthetic tissue in response to wear debris-induced inflammation factors (WDIF) has been identified as one of the primary contributors to the progression of osteolysis in aseptic loosening (AL) of arthroplasty implants. However, the dynamics of monocy...

Ferroptosis and Iron Dyshomeostasis as Drivers of Wound Chronicity in Diabetic Foot Ulcers: Pathophysiological Mechanisms and Targeted Therapeutic Strategies

Background diabetic foot ulcers (DFUs) carry 5-year mortality rates of 50%–70% and recurrence rates of 65% at three to five years. Standard-of-care protocols fail to resolve wound chronicity in a substantial proportion of patients, reflecting incomplete understanding of the cellu...

Interactive influence of in-situ annealing temperature and thermal processing parameters on defect minimization and strength enhancement in FDM-printed PEEK

Abstract PolyEther Ether Ketone (PEEK) fused deposition modelling (FDM) has become a viable manufacturing technique for creating high-performance parts utilised in high-temperature engineering, biomedical, and aerospace applications. However, poor heat control during FDM printing...
