Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine

Medicinal Research Reviews, EarlyView.
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

Systematic Review of Patient‐ and Observer‐Reported Outcomes of Fatigue in Pediatric Neuromuscular Disorders

Muscle &Nerve, EarlyView.
ABSTRACT Fatigue is a burdensome symptom for pediatric populations with neuromuscular disorders, often assessed using patient‐ and observer‐reported outcomes. The three aims of this systematic review are to: (1) explore, summarize and critically appraise primary studies that measure fatigue in pediatric neuromuscular disorders using patient‐ and ...

Let's Talk About Bone Cylinders. Taphonomy of Carnivores and Humans

International Journal of Osteoarchaeology, EarlyView.
ABSTRACTBone cylinders are a distinctive structure predominantly produced by durophagous carnivoran species during the consumption of long bones, in which the diaphyseal canal remains intact while both epiphyses are removed or consumed. This study evaluates the significance of this morphology, traditionally attributed to extant and extinct hyena ...

Tooth Enamel Carbon and Oxygen Isotope Ratios Reveal Shifts in Neolithic Caprine Husbandry on the Dalmatian Coast, Croatia

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT Stable isotope analysis of sequential samples of ancient sheep and goat tooth enamel is used to investigate feeding, breeding, and mobility strategies at Neolithic villages on the Dalmatian Coast of Croatia. δ13C values demonstrate clear enrichment of caprine diet in 13C from the Early (c. 8.1–7.5 kya cal.

Dental Modifications Indicate Social Identity in the Insular Region of Wallacea, Indonesia 3634–2268 Cal BP

International Journal of Osteoarchaeology, EarlyView.
ABSTRACT The dispersal of Austronesian‐speaking people across Island Southeast Asia and the Pacific during the Late Holocene was associated with the spread of shared cultural practices, including intentional dental modifications. These practices, like tooth ablation and dental staining (likely with betel quid), are interpreted as embodied expressions ...
