We studied the role of autochthonous microflora from body cavities in the development of tissue hypoxia and instability of cell membranes. In children with tuberculosis dysbiosis manifested in nonspecific quantitative changes in the intestinal microflora and the presence of coxsackievirus antigens in the urine. DNA-containing viruses with pronounced immunosuppressive activity (e.g., herpesvirus, measles virus, and rubella virus) were found in most children. Microbiological and virological changes were accompanied by the appearance of laboratory signs for tissue hypoxia, which included inhibition of Krebs cycle dehydrogenases and alpha-glycerophosphate pathway in blood lymphocytes. Regression analysis revealed a relationship between the content of extraintestinal coxsackieviruses and inactivation of alpha-glycerophosphate dehydrogenase, succinate dehydrogenase and ratio of facultatively anaerobic bacteria in microbiocenosis, and expression of acid phosphatase and total population of malonate-positive enterobacteria, staphylococci, yeasts, and enterococci.

Focal adhesion kinase mediates microvascular leakage and endothelial barrier dysfunction in ischemia-reperfusion injury.

Intestinal ischemia-reperfusion (I/R) injury occurs under various surgical or disease conditions, where tissue hypoxia followed by reoxygenation results in the production of oxygen radicals and inflammatory mediators. These substances can target the endothelial barrier, leading to microvascular leakage. In this study, we induced intestinal I/R injury in mice by occluding the superior mesenteric artery, followed by removing the clamp to resume blood circulation.

Aims: Accumulating studies have demonstrated obstructive sleep apnea (OSA) is strongly associated with metabolic syndrome (MetS) and inflammatory response in adipose tissue. Chronic intermittent hypoxia (CIH) has been proved leading to M1 macrophage polarization that contributes to adipose tissue inflammation, but the molecular mechanism remains unclear. Epigenetic regulation of RNA has been found playing crucial roles in incremental diseases.

Article Synopsis
- This study investigates the biological changes in rabbit corneas caused by two light-activated corneal stiffening methods: riboflavin with UVA and WST11 with NIR.
- Differentially expressed proteins were identified following treatments, showing RF-D/UVA affected cell metabolism and keratocyte differentiation, while WST-D/NIR influenced extracellular matrix regulation.
- The findings reveal a metabolic shift towards glycolysis in RF-D/UVA treated corneas compared to normal respiration in WST-D/NIR treated corneas, highlighting the distinct biological effects of each treatment.
Chronic fetal hypoxia and antenatal Vitamin C exposure differentially regulate molecular signalling in the lung of female lambs in early adulthood.

Introduction: Chronic fetal hypoxia is commonly associated with fetal growth restriction and can predispose to respiratory disease at birth and in later life. Antenatal antioxidant treatment has been investigated to overcome the effects of oxidative stress to improve respiratory outcomes. We aimed to determine if the effects of chronic fetal hypoxia and antenatal antioxidant administration persist in the lung in early adulthood.

Significance: Protoporphyrin IX (PpIX) delayed fluorescence (DF) is inversely related to the oxygen present in tissues and has potential as a novel biomarker for surgical guidance and real-time tissue metabolism assessment. Despite the unique promise of this technique, its successful clinical translation is limited by the low intensity emitted.
Aim: We developed a systematic study of ways to increase the PpIX DF signal through acquisition sampling changes, allowing optimized imaging at video rates.
