Lithic analysis in African archaeology: Advances and key themes
Archaeometry, EarlyView.Abstract Stone artifacts (lithics) preserve for extended periods; thus they are key evidence for probing the evolution of human technological behaviors. Africa boasts the oldest record of stone artifacts, spanning 3.3 Ma, rare instances of ethnographic stone tool‐making, and stone tool archives from diverse ecological settings, making it an anchor for ...

Disproportional ventilatory response to incremental exercise in individuals with cerebral palsy
Developmental Medicine &Child Neurology, EarlyView.Individuals with cerebral palsy demonstrate a disproportionate ventilatory response during incremental exercise. Compared with typically developing peers, respiratory frequency increases earlier and at comparable exercise intensities, contributing to higher perceived exertion and reduced ventilatory efficiency. At task failure, respiratory frequency is

Biomechanical effects of equine training aids: A systematic review
Equine Veterinary Education, EarlyView.Summary Equine training aids, including auxiliary reins such as draw reins, Pessoa‐type systems and side reins, are widely used during lungeing and ridden exercise to improve posture, back engagement and movement quality. Despite their extensive practical application, the biomechanical effects of these devices remain poorly defined and are often ...

Equine Veterinary Journal, EarlyView.Abstract The need for comprehensive equine welfare assessments has become particularly evident amid ongoing debates about the social licence to operate in equestrian sports. During exercise, multiple physiological systems, principally the cardiovascular, respiratory, muscular, thermoregulatory, endocrine, and locomotory systems, undergo complex ...

Equine Veterinary Journal, EarlyView.Abstract Background Flexion tests are commonly used in equine locomotion examinations to identify underlying locomotor issues, yet their neuromuscular effects remain poorly understood. Response variability raises concerns about their clinical value in lameness assessments and pre‐purchase evaluations.

Functional morphology of trabecular bone in the calcaneus of African apes
Journal of Anatomy, EarlyView.Pan exhibits significantly higher calcaneal tuberosity trabecular thickness (Tb.Th) and bone volume fraction (BV/TV) than Gorilla, potentially reflecting higher triceps surae forces for vertical climbing. Both taxa have significantly higher Tb.Th and BV/TV in the anterior calcaneus; the difference is exaggerated in Gorilla, potentially reflecting ...

Journal of Anatomy, EarlyView.The pyramidalis (Py) is a small triangular‐shaped anterior abdominal wall muscle, the function of which remains uncertain. We used shear wave elastography to test the hypothesis that Py contributes to stiffness of the linea alba. Our results indicate that Py contraction results in a significant increase in LA stiffness, supporting the previously ...
