Modelling the effect of varying metabolic rate and cardiac output on estimated tissue and blood O2 and CO2 levels in an extreme deep‐diver, the goose‐beaked whale (Ziphius cavirostris)

open access: yesExperimental Physiology, EarlyView.
Abstract High‐resolution movement data from Cuvier's beaked, or goose‐beaked whale (Ziphius cavirostris, hereafter Ziphius, n = 8) tag deployments (4.1–19.2 days) were used to estimate blood and tissue O2 and CO2 levels. Acceleration and magnetometry data were used to estimate the locomotion cost (LC) from the relationship between activity and the O2 ...

Carbohydrates as a source of energy and matter for the origin of life [PDF]

open access: yes
Recently, we proposed a new model of early glycolysis in which the oxidation of glyceraldehyde self-hemiacetals yielded energy rich polyglyceric acid instead of energy rich thioesters.

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 ...

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Heterogeneous metabolic response of endothelial cells from different vascular beds to experimental hyperglycaemia and metformin

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Diabetes mellitus is associated with vascular pathology that leads to vascular complications in several tissues, such as retinopathy of the eye. Endothelial dysfunction plays a pivotal role in the progression of each complication.
