BACKGROUND
Chronic fatigue stress (CFS) is an important health problem with unknown causes and unsatisfactory prevention strategies, often characterized by long-lasting and debilitating fatigue, myalgia, impairment of neuro-cognitive functions along with other common symptoms. The present study has
Nitric oxide (NO) plays important, but incompletely defined roles in skeletal muscle. NO exerts its regulatory effects partly though S-nitrosylation, which is balanced by denitrosylation by enzymes such as S-nitrosoglutathione reductase (GSNOR), whose functions in skeletal muscle remain to be fully
A thirty-two year old female had chronic progressive external ophthalmoplegia (CPEO), exertional fatigue, dysarthria, dysphagia, and bilateral hearing impairment. Histochemical stains, obtained from the right vastus lateralis, showed ragged-red fibers and wide-spread abnormalities in the number,
An animal model for the human condition of mitochondrial myopathy has been established and characterized physiologically and biochemically. The NADH: coenzyme Q reductase inhibitor diphenyleneiodonium [Bloxham (1979) Biochem. Soc. Trans. 7, 103-106] was either infused acutely in vivo into rat hind
Chronic administration of the NADH-CoQ reductase inhibitor, diphenyleneiodonium to rats at two dose levels, 1.0 and 1.5 mg/kg per day, caused a 40% and 60% reduction, respectively, in the in vitro rate of NAD-linked respiration by skeletal muscle mitochondria. At the highest dose, muscle fatigue,
Sepiapterin reductase (SR) catalyses the last step in the tetrahydrobiopterin biosynthesis pathway; it converts 6-pyruvoyl-tetrahydropterin (6-PTP) to BH(4) in an NADPH-dependent reaction. SR deficiency is a very rare autosomal recessive disorder with normal phenylalanine (Phe) concentration in
BACKGROUND
In the current Phase II study, the authors evaluated the association between genomic polymorphic variants in uridine diphosphate glucuronosyl transferase (UGT1A1), methylenetetrahydrofolate reductase (MTHFR), and thymidylate synthase (TS) genes, and the incidence of the adverse effects of
BACKGROUND In the present study, we aimed to retrospectively analyze the correlation between toxicity of pemetrexed (PEM) chemotherapy and methylenetetrahydrofolate reductase (MTHFR) C677T polymorphisms in patients with advanced non-squamous non-small cell lung cancer (non-sq NSCLC). MATERIAL AND
Introduction: Cancer-related fatigue (CRF) is the most debilitating symptom with the greatest adverse side effect on quality of life. The etiology of this symptom is still not understood. The purpose of this study was to examine the relationship between mitochondrial gene expression,
OBJECTIVE
To investigate the effective dose and the possible mechanism of the anti-fatigue effect of ginsenosides and then deduce to the recommended intake of human body.
METHODS
Healthy adult male SD rats intook ginsenosides solution every day through stomach at doses of 50, 150, 250 mg/kg per day,
1. Chronic fatigue syndrome is characterized by muscle fatigue and pain at rest, symptoms which are usually exacerbated with exercise. Although various studies have shown minor, non-specific morphological and biochemical changes in muscle of patients with chronic fatigue syndrome, no consistent
OBJECTIVE
The isoprenoid pathway was assessed in 15 patients with chronic fatigue syndrome (CFS). The pathway was also assessed in individuals with differing hemispheric dominance to assess whether hemispheric dominance has any correlation with these disease states.
METHODS
The isoprenoid
BACKGROUND
3-Aminopyridine-2-carboxaldehydethiosemicarbazone (3-AP) is a novel small molecule ribonucleotide reductase (RR) inhibitor which is more potent than hydroxyurea, the prototype of RR inhibitors. 3-AP enhances the cellular uptake and DNA incorporation of gemcitabine in tumor cell lines. We
We investigated whether there is any relationship between biochemical and clinical parameters of migraine and methylenetetrahydrofolate reductase (MTHFR) gene C677T polymorphism, associated with the migraine subtypes, symptoms, and gender. A total of 150 migraine patients with and without aura (MA
