LRP receptors in chondrocytes are modulated by simulated microgravity and cyclic hydrostatic pressure.

PLoS ONE, 2019
Mechanical loading is essential for the maintenance of musculoskeletal homeostasis. Cartilage has been demonstrated to be highly mechanoresponsive, but the mechanisms by which chondrocytes respond to mechanical stimuli are not clearly understood.

Concurrent ANNPE and vertebral T‐cell lymphoma in a dog: A case report

Journal of Small Animal Practice, EarlyView.
Acute non‐compressive nucleus pulposus extrusion (ANNPE) is a recognised cause of peracute spinal cord injury in dogs, involving sudden extrusion of non‐degenerated nucleus pulposus with minimal compression. While often linked to vigorous activity, its triggers remain unclear.

Women in space: A review of known physiological adaptations and health perspectives

Experimental Physiology, EarlyView.
Abstract Exposure to the spaceflight environment causes adaptations in most human physiological systems, many of which are thought to affect women differently from men. Since only 11.5% of astronauts worldwide have been female, these issues are largely understudied.

Skeletal muscle in MuRF1 null mice is not spared in low-gravity conditions, indicating atrophy proceeds by unique mechanisms in space

Scientific Reports, 2019
Microgravity exposure is associated with loss of muscle mass and strength. The E3 ubiquitin ligase MuRF1 plays an integral role in degrading the contractile apparatus of skeletal muscle; MuRF1 null (KO) mice have shown protection in ground-based models ...

Turning over new ideas in human skeletal muscle proteostasis: What do we know and where to from here?

Experimental Physiology, EarlyView.
Abstract Understanding the turnover of proteins in tissues gives information as to how external stimuli result in phenotypic change. Nowhere is such phenotypic change more conspicuous than skeletal muscle, which can be effectively remodelled by increased loading, ageing and unloading (disuse), all of which are subject to modification by nutrition and ...

The relationship of sphingolipid mechanisms with oxidative stress and changes in mitochondria during functional unloading of postural muscles

Acta Biomedica Scientifica
Background. Prolonged inactivity of skeletal muscles is accompanied by the development of oxidative stress and changes in sphingolipid metabolism. The relationship of sphingolipid mechanisms with generation of reactive oxygen species (ROS) in muscles ...

Nitrite supplementation alleviates cerebrovascular dysfunction in chronically stressed mice, but cognitive decline remains

Experimental Physiology, EarlyView.
Abstract This study aimed to determine whether sodium nitrite supplementation prevented chronic stress‐induced cerebrovascular dysfunction and cognitive decline. We hypothesize that nitrite supplementation will prevent the oxidative environment and cerebrovascular dysfunction associated with chronic stress and maintain cognitive health.

The effect of HIIT before and after hindlimb suspension on the gene expression of MSTN and ActrIIB in skeletal muscle of male Wistar rats [PDF]

فصلنامه ابن سینا
Background and aims: Exercise training is employed as a practical method to combat muscle atrophy. The purpose of this study was to investigate the effects of high-intensity interval training (HIIT) conducted before and after hindlimb suspension (HLS) on

Myocellular adaptations to short‐term weighted wheel‐running exercise are largely conserved during C26‐tumour induction in male and female mice

Experimental Physiology, EarlyView.
Abstract This study investigated whether performing a translatable murine model of concurrent training after tumour induction affects adaptations in juvenile male and female tumour‐bearing mice. Male and female Balb/c mice were injected bilaterally with colon‐26 adenocarcinoma (C26) cells or PBS at 8 weeks of age.
