Spatiotemporal cellular dynamics of the notochord shape intervertebral disc morphogenesis in the mouse embryo through apoptosis and proliferation

Developmental Dynamics, EarlyView.
Abstract Background The notochord is a midline structure essential for vertebrate embryogenesis, contributing to the development of the nervous system, digestive tract, and vertebral column. In particular, notochord signaling is indispensable for proper patterning and coordinated development of alternating vertebrae and intervertebral discs (IVDs ...

Do witnesses of functional/dissociative seizures recall them accurately? A UK experimental study of semiology recall at clinically relevant time points with a pilot intervention

Epilepsia, EarlyView.
Abstract Objective Different causes of transient loss of consciousness (TLOC) carry distinct risks and require different management. Early accurate diagnosis is essential to guide counseling, investigation, and referral. In routine practice, frontline clinicians and specialists often rely on eyewitness accounts, yet the reliability of witness testimony

Caring Flexibly? Working Conditions and the Supply of Adult Care

Health Economics, EarlyView.
ABSTRACT Although flexible employment policies can help employed individuals balance caregiving and paid work, limited evidence has been devoted to examining the effect of working flexibly on the supply of care to older adults. In this paper, we study the impact of flexible working conditions on the supply of informal adult care and mental health.
