The mechanism of labor in nonhuman primates: A look inside

open access: yesThe Anatomical Record, EarlyView.
Abstract While in humans, the flexed position of the fetus and its rotating course down the birth canal are well documented, in other primates the mechanism of labor is unknown. Despite the lack of comparative data, it is commonly assumed that the human obstetric mechanism is unique, and anthropologists have disputed when and why the transition to the ...

Human evolution and the obstetrical dilemma: The pelvic floor hypothesis

open access: yesThe Anatomical Record, EarlyView.
Abstract Human childbirth is mechanically difficult because a large‐headed, broad‐shouldered fetus must pass through a comparatively narrow, twisted bony birth canal. Traditional explanations of this “obstetrical dilemma” emphasize the role of bipedal locomotion in inhibiting the evolution of a wider, more spacious pelvis.

Duck Orbivirus and Egg Production: A Newly Identified Duck Orbivirus Is the Etiological Agent of Egg Production Decline in Chinese Breeder Ducks

open access: yesAnimal Research and One Health, EarlyView.
Field samples from breeder duck farms with egg‐production decline were subjected to viral detection, genome sequencing, and virus isolation. Experimental infection demonstrated that duck orbivirus (DORV) causes a significant and persistent reduction in egg production in breeder ducks.

Stabilization by Crosslinking of β‐Galactosidase Immobilized by Adsorption for Application in a Continuous Lactose Removal Process

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Adsorption is the simplest method of enzyme immobilization, but it often requires additional treatments to improve stability. These treatments, however, may impact enzymatic activity. This study investigated the effect of crosslinking on the stability of β‐galactosidase immobilized by adsorption on A‐568 resin and its implications for ...

When meta‐analyses mislead: Promises and pitfalls in teratology counselling

open access: yesBritish Journal of Clinical Pharmacology, EarlyView.
Meta‐analysis has become a central tool for evidence synthesis in clinical teratology, offering the promise of increased statistical power, earlier signal detection and consolidated guidance for teratology counselling. When conducted rigorously and interpreted carefully, pooled analyses can provide clinicians with a structured basis for risk ...
