Impaired Windkessel function and proximal aortic stiffness: Linking vascular ageing to cognitive decline

open access: yesExperimental Physiology, EarlyView.
Abstract Central arterial stiffening, particularly of the proximal aorta, is increasingly recognised as a pivotal contributor to cardiovascular disease, dementia, and mild cognitive impairment. Loss of Windkessel function amplifies pulsatile pressure, reduces diastolic perfusion and accelerates microvascular damage in the brain.

Toxicity of Dietary Lead in Japanese Quail ,

open access: yesPoultry Science, 1975
The toxicity of dietary lead in Japanese quail was investigated. The data indicated that dietary lead, in the form of lead acetate, was toxic to young quail at the level of 500 p.p.m. and this toxicity was evidenced by an inhibition of normal growth and by anemia.

Behavior of Japanese quail in different air velocities and air temperatures

open access: yes, 2017
The objective of this work was to evaluate the combined effects of air temperature and air velocity on the behavior of Japanese quail ( Coturnix coturnix japonica ). A total of 216 Japanese quail in their initial laying phase were used. Bird behavior was

Cerebrovascular regulation during heat stress

open access: yesExperimental Physiology, EarlyView.
Abstract Given that the brain is a highly metabolic organ and is enclosed by the skull, effective regulation of cerebral blood flow (CBF), not only for oxygen and nutrients supply but also as a means of convective heat exchange, is critical for preventing excessive elevations in brain temperature.

Uterus-specific transcriptional regulation underlies eggshell pigment production in Japanese quail

open access: yesPLoS ONE, 2022
The precursor of heme, protoporphyrin IX (PPIX), accumulates abundantly in the uteri of birds, such as Japanese quail, Coturnix japonica, which has brown-speckled eggshells; however, the molecular basis of PPIX production in the uterus remains largely ...

Cerebral blood flow regulation, central arterial stiffness and traumatic brain injury: Effects of aerobic exercise training

open access: yesExperimental Physiology, EarlyView.
Abstract Advanced age is the strongest risk factor for Alzheimer's disease and related dementias (ADRDs). Traumatic brain injury (TBI) has also been recognized as a risk factor for ADRD, potentially contributing to an earlier onset of the disease. Thus, elucidating the mechanisms underlying brain ageing and TBI is critical for developing strategies to ...

Passive hyperthermia increases blood circulation in specific regions, largely independent of conduit artery mechanics and cardiac performance

open access: yesExperimental Physiology, EarlyView.
Abstract Passive hyperthermia increases net peripheral and systemic blood flow in humans and other animals, yet the underlying haemodynamic forces that selectively accelerate blood movement remain incompletely characterized. Wave intensity analysis offers insight into the respective contributions of the heart and the vascular system to changes in blood

Phosphorus requirements of laying Japanese quails

open access: yesPoultry Science
Available phosphorus (AP) is a crucial nutrient for laying quails, influencing eggshell quality and overall production performance. This study investigated the optimal levels of dietary AP in laying quails from 10 to 16 weeks of age. A total of 375 laying quails were used in a completely randomized design with five experimental diets (0.25, 0.30, 0.35,

Caloric restriction and aerobic exercise differentially counteract muscle–tendon dysfunction following diet‐induced obesity in C57BL/6J mice

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Diet‐induced obesity induced fibro‐adipogenic remodelling of the muscle–tendon unit, characterized by increased fibrosis, reduced specific force, impaired relaxation kinetics, elevated hysteresis, and reduced aerobic capacity and glucose tolerance.
