Abstract The obstetrical dilemma hypothesis (ODH) proposes an evolutionary trade‐off between obstetric requirements and locomotor performance. However, whether external pelvic breadth measures influence walking energetics during human growth remains poorly understood.

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

Abstract All infant mammals must suckle in order to effectively acquire milk from a nipple. Yet, not all infants are able to do so. Preterm infants in particular face significant feeding challenges, often failing to establish successful breastfeeding due to complex neurophysiologic challenges.

Human digital Meissner's corpuscles are not doubly innervated
Abstract Recent studies have shown that murine and avian Meissner‐like corpuscles are innervated by two distinct mechanoreceptor afferents with different functional properties. In addition, there is evidence that one subpopulation of Meissner corpuscles of monkeys is doubly innervated by mechanoreceptors and nociceptors.

Abstract Meissner corpuscles are rapidly adapting mechanoreceptors involved in tactile discrimination in human glabrous hand skin. Detailed information on their regional distribution and variation across age, sex, and hand side remains limited. This study mapped Meissner corpuscles in 17 phalangeal and palmar regions from 46 individuals (27 male and 19

Assessment of gestational age in twins
Gestational age was estimated by the method of Dubowitz et al. (1970) in 33 pairs of twins. In spite of marked differences of up to 20% in birthweight between the two members of a twin pair, the mean estimated gestational age of the heavier twins did not

Intensive or organic farming systems may expose pigs to management or environmental challenges. Our preliminary results concluded that organic farming might enhance adaptive immune function, showing that improvements in welfare can translate into measurable immunological benefits, based on the correlation between welfare assessment and physiological ...

Gestational age, birth weight, and perinatal complications in mothers with diabetes and impaired glucose tolerance: Japan Environment and Children’s Study cohort [PDF]
We aimed to determine the risk of perinatal complications during delivery in mothers with non-normal glucose tolerance in a large Japanese birth cohort. We analysed data of 24,295 neonate-mother pairs in the Japan Environment and Children's Study cohort ...

Gastrointestinal nematode infections damage the gastrointestinal epithelial tissues of ruminants, affecting nutrient utilization and overall production performance. This review outlines host‐gastrointestinal nematode interactions and discusses integrated control strategies, including nutritional supplementation, grazing management, vaccines, and ...

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable
