Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight

open access: yesExperimental Physiology, EarlyView.
Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

Exploring neuronal mechanisms of osteosarcopenia in older adults

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend The mechanosensitive osteocytic network within the bone matrix acts as a receptor and plays a crucial role in the functional adaptation of bone to mechanical loading. Through mechanotransduction, osteocytes convert mechanical impulses into electrical signals, which are transmitted via afferent nerves to sympathetic preganglionic ...

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Mitochondrial oxidative stress, calcium and dynamics in cardiac ischaemia‐reperfusion injury

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Heart attack causes ischaemia–reperfusion injury in cardiomyocytes. Mitochondria generate reactive oxygen species (ROS), leading to oxidative stress. High levels of mitochondrial calcium (Ca2+) activate the mitochondrial permeability transition pore (mPTP), and excess ROS levels can lower the Ca2+ required to activate the mPTP ...
