The Role of Oxidative Stress in Periodontitis

Journal of Periodontal Research, EarlyView.
Oxidative stress is involved in multiple chemical reactions that take place in different intracellular organelles: mitochondria, rough endoplasmic reticulum, peroxisomes, autophagy, and aging, and can be influenced by exogenous factors: nutrition, physical activity, psychological status, environmental conditions, microbiome, and drugs.

Characteristics of metabolic myopathies among Egyptian patients

The Egyptian Journal of Neurology, Psychiatry and Neurosurgery
Background Metabolic Myopathies are characterized by defect in muscle energy production. The main symptoms are exercise intolerance, fatigue, myalgias, rhabdomyolysis and \or weakness, they present with episodic or fixed manifestations.

Daridorexant‐ Case Report of Possible Side‐Effect in Rare Mitochondrial Disorder

Journal of Sleep Research, EarlyView.
ABSTRACT This case report describes a 40‐year‐old woman with maternally inherited diabetes and deafness (MIDD), a rare mitochondrial disorder, who received treatment with daridorexant due to severe chronic insomnia. She developed progression of her MIDD symptoms during treatment.

Mitophagy in skeletal muscle: Impact of ageing, exercise and disuse

Experimental Physiology, EarlyView.
Abstract Skeletal muscle plays an important role in whole‐body health, quality of life and regulation of metabolism. The maintenance of a healthy mitochondrial pool is imperative for the preservation of skeletal muscle quality and is mediated through mitochondrial quality control consisting of mitochondrial turnover mediated by a balance between ...

Niacin supplementation in a child with novel MTTN variant m.5670A>G causing early onset mitochondrial myopathy and NAD+ deficiency

Myopathy is a common manifestation in mitochondrial disorders, but the pathomechanisms are still insufficiently studied in children. Here, we report a severe, progressive mitochondrial myopathy in a four-year-old child, who died at eight years.

Canonical and non‐canonical functions of proteins regulating mitochondrial dynamics in mammalian physiology

The Journal of Physiology, EarlyView.
Abstract figure legend Mitochondria are highly dynamic organelles that continuously remodel their architecture through coordinated cycles of fusion and fission. This review examines the four key GTPases that orchestrate mitochondrial dynamics in mammals: MFN1, MFN2, OPA1, and DRP1.

Intramuscular pathways of maladaptation in overtraining syndrome

The Journal of Physiology, EarlyView.
Abstract figure legend The transition from adaptive overreaching to maladaptive overtraining and mechanisms through which excessive training load can lead to performance decline. Four interconnected pathophysiological domains are highlighted: neural fatigue, involving both central and peripheral components such as altered sensory feedback and reflex ...

The mitochondrial‐targeted antioxidant SkQ1 prevents skeletal muscle mitochondrial‐apoptotic but not necroptotic signalling during ovarian cancer

The Journal of Physiology, EarlyView.
Abstract figure legend An evaluation of the degree to which mitochondrial hydrogen peroxide emission (mH2O2)‐mediated apoptotic and necroptotic signalling contributes to skeletal muscle atrophy in an orthotopic epithelial ovarian cancer (EOC) model. To determine whether attenuating mH2O2 could prevent regulated cell death signalling and mitigate muscle
