Impairment by Hypoxia or Hypoxia/Reoxygenation of Nitric Oxide–Mediated Relaxation in Isolated Monkey Coronary Artery: the Role of Intracellular Superoxide

open access: yesJournal of Pharmacological Sciences, 2011
.: To investigate the effect of hypoxia or hypoxia/reoxygenation on vascular smooth muscle function, mechanical response of monkey coronary artery without endothelium was studied under normoxia, hypoxia, and hypoxia/reoxygenation.

Is There a Difference in Occurrence of Complications Between Adults With Hemoglobin SS and Hemoglobin SC Disease: An Extended Systematic Review

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Sickle cell disease (SCD) is characterized by both acute and chronic complications. The clinical manifestation of these complications differs between genotypes. Given the large amount of research already published, this systematic review aims to offer a complete overview of types of sickle cell complications between adults in the most common ...

Mathematical models of repopulation and reoxygenation in radiotherapy

open access: yesThe British Journal of Radiology, 1990
Mathematical models of the effect of ionizing radiation on tumours have not, so far, received general acceptance, and Wheldon (1989) warns of the dangers of over-generalization. Nevertheless, the construction of models may have a certain value, in that we are forced to define our assumptions with clarity. It is interesting to compare two

Ubiquitin and ubiquitin‐like modifications in the endoplasmic reticulum stress response

open access: yesThe FEBS Journal, EarlyView.
Endoplasmic reticulum (ER) stress activates various proteostasis control processes, including the unfolded protein response, ribosome‐associated quality control, and ER‐associated degradation. Ubiquitin and ubiquitin‐like modifications dynamically regulate these processes to determine cell fate, promoting adaptation or inducing cell death.

Intermittent hypoxia increases lipid insulin resistance in healthy humans: A randomized crossover trial

open access: yesJournal of Sleep Research, Volume 34, Issue 2, April 2025.
This scheme illustrates the main results of the present study showing an increase in circulating free fatty acids (FFA) that are likely to be related to several mechanisms like decrease in FFA insulin sensitivity and increase in FFA production. Significant changes are labelled in white, and non‐significant or hypothesis are labelled in pale green ...

Phosphoproteomic changes in response to anoxia are tissue-specific in the anoxia-tolerant crucian carp (Carassius carassius)

open access: yesFrontiers in Physiology
Crucian carp (Carassius carassius), a freshwater fish, can survive chronic anoxia for several months at low temperatures. Consequently, anoxia-related physiological and biochemical adaptations in this species have been studied for more than half a ...

Expression characteristics of dual‐specificity phosphatase 2 and hypoxia‐inducible factor‐1α in acute kidney injury and preliminary study of the effect of dual‐specificity phosphatase 2 on HK‐2 cells

open access: yesExperimental Physiology, EarlyView.
ABSTRACT Acute kidney injury (AKI) is a global health problem with significant long‐term harm if the prognosis is poor. Dual‐specificity phosphatase 2 (DUSP2) is involved in key regulatory pathways in several disease processes, but its function in renal pathophysiology is unclear.

Down-regulation of NDRG1 promotes migration of cancer cells during reoxygenation.

open access: yesPLoS ONE, 2011
One characteristic of tumor microenvironment is oxygen fluctuation, which results from hyper-proliferation and abnormal metabolism of tumor cells as well as disorganized neo-vasculature. Reoxygenation of tumors can induce oxidative stress, which leads to

Substrate‐specific mitochondrial dysfunction and metabolomic profiles in type 2 diabetic rat hearts

open access: yesExperimental Physiology, EarlyView.
Abstract Type 2 diabetes (T2D) greatly alters cardiac fuel handling, yet how mitochondrial function adapts to the diabetic substrate environment remains unclear. This study investigated substrate‐specific cardiac mitochondrial bioenergetics from a T2D rat model induced by a high‐fat diet and low‐dose streptozotocin.

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).
