Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Preoperative Diagnosis of Adult Intussusception Caused by Small Bowel Lipoma

Case Reports in Gastroenterology, 2009
Adult intussusception is rare, accounting for only 5% of all intussusceptions, for which preoperative diagnosis is difficult. We herein report a preoperatively diagnosed case of adult intussusception caused by a small bowel lipoma.

Reduction of Ribonucleotide Reductase Subunit RRM2 Potentially Impairs Gut Function of Woody Breast Broilers

Animal Research and One Health, EarlyView.
Woody breast compromises meat quality leading to reduced consumer appeal. Although its causes are unclear, improvements observed with certain dietary supplements suggest that gut health may influence woody breast development. Ribonucleotide reductase subunit RRM2 is vital for mitochondrial function and gastrointestinal integrity, and alteration in its ...

The paper puzzle as an active learning tool in the teaching of anatomy: A qualitative study of perceptions in students and near‐peer teachers

Anatomical Sciences Education, EarlyView.
Abstract Active learning strategies enhance medical education by fostering self‐directed learning, communication, and problem‐solving skills. The paper puzzle, a game‐based learning approach, provides an engaging way to reinforce anatomical knowledge and promote collaboration.

Cartooning in Biological Learning

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Teaching bioscience subjects requires helping students understand complicated and abstract concepts. An effective method of helping students understand these abstract topics is the use of concept cartoons. Concept cartoons are cartoon‐style drawings that illustrate everyday situations. In constructivism, learners create their own knowledge and

Bowel Intussusception in Adults: Think Cancer!

Case Reports in Gastroenterology, 2020
Intussusception is a rare phenomenon in adults and usually presents with bowel obstruction. Unlike child intussusception, adult intussusception is seldom idiopathic and frequently associated with secondary causes such as benign and malignant tumors ...

Optimizing biophysical properties of cellular niches to enhance stem cell‐derived extracellular vesicle function in musculoskeletal regeneration

BMEMat, EarlyView.
Extracellular vesicles (EVs) derived from stem cells show promise for applications in regenerative medicine, but their scalability and yield remain challenges. This review explores the approaches for biophysical modulations within cell niches on EV properties, discusses the current clinical application of EVs, and provides an outlook on the existing ...

Exosome as bioactive nanovesicle for diagnostic and therapeutic applications in periodontitis

BMEMat, EarlyView.
This review introduces the mechanism that exosomes participate in the pathogenesis of periodontitis and their potential as biomarkers for early diagnosis and summarizes the application of cell‐ or plant‐derived exosomes or engineered exosomes in periodontitis or periodontal regeneration while proposing the perspective of translational application of ...

Early evolutionary history of the seed

Biological Reviews, EarlyView.
ABSTRACT The seed is an essential stage in the life history of gymnospermous and angiospermous plants, facilitating both their survival and dispersal. We reappraise knowledge of the evolutionary history of the gymnospermous seed, from its origin in the late Devonian through to the well‐known end‐Permian extinctions – an interval encompassing the ...
