As advances in analytical separation techniques, mass spectrometry instrumentation, and data processing platforms continue to spur growth in the lipidomics field, more structurally unique lipid species are detected and annotated. The lipidomics community is in need of benchmark reference values to assess the validity of various lipidomics workflows in providing accurate quantitative measurements across the diverse lipidome. LipidQC addresses the harmonization challenge in lipid quantitation by providing a semi-automated process, independent of analytical platform, for visual comparison of experimental results of National Institute of Standards and Technology Standard Reference Material (SRM) 1950 Metabolites in Frozen Human Plasma against benchmark consensus mean concentrations derived from the NIST Lipidomics Interlaboratory Comparison Exercise...

BACKGROUND: Small heterodimer partner (SHP) is an important transcriptional factor involved in the regulation of glucose, lipid, and bile acid metabolism in the liver. SHP has been reported to be down-regulated in ovariectomized (Ovx) mice and up-regulated by estrogens suggesting a link between estrogens and SHP. The aim of the present study was to determine the effects of exercise training on SHP and key molecular markers of cholesterol and bile acid homeostasis in Ovx rats under cholesterol feeding...

PURPOSE: Due to the suboptimal uptake of cardiac rehabilitation (CR), alternative models have been proposed. This study compared the effectiveness of a traditional supervised program in a medical setting versus a hybrid CR model, where patients transition to unsupervised programming. METHODS: This was a prospective, 2-arm, nonrandomized study. Health-related quality of life (HRQoL), functional capacity, physical activity, diet, smoking, blood pressure, lipids, blood glucose, anthropometrics, and depressive symptoms were assessed before and after the 8-week program models...

PURPOSE OF REVIEW: Postprandial lipemia (PPL), the prolonged increase in plasma triglyceride-rich lipoproteins following food consumption, is an independent risk factor for cardiovascular disease. Genetic variation, environment and the interplay between these direct an individual's postprandial lipid response. From such interplay, inducible and reversible epigenetic changes arise. Increasing evidence suggests epigenetic variation contributes to postprandial response in lipids and risk...

Regular moderate physical activity positively affects health, fitness, and body composition; it regulates the pro- and anti-inflammatory cytokines levels. Vitamin D plays an important regulatory role; its adequate levels correlate with low values of inflammation markers and an increase in muscle strength and fitness in exercising people. The study's aim was to evaluate changes in somatic variables, oxidative stress, and inflammation markers, as well as blood calcidiol concentration in middle-aged healthy women after 12 weeks of aerobics classes-endurance exercises, including choreographic sequences, aiming to improve fitness and motor coordination...

The purpose of this study was to investigate the combinatory effects of an isoflavone (ISO)-rich diet and exercise on fat mass and lipid metabolism in ovariectomized (OVX) rats. Therefore the female Wistar rats were sedentary, performed an intense treadmill uphill running, received ISOs, or a combination of ISOs and running after ovariectomy. The exercise reduced visceral fat mass, adipocyte size and serum leptin in Sham animals and antagonized the increases of these parameters induced by OVX. ISOs reduced OVX induced increase of serum leptin...

Exercise training reduces intrahepatic lipid (IHL) content in people with elevated liver fat content. It is unclear, however, whether exercise training reduces IHL content in people with normal liver fat content. Here, we measured the effect of exercise training on IHL content in people with and people without non-alcohol fatty liver. We further measured changes in insulin sensitivity and hepatic energy metabolism. Eleven males with non-alcoholic fatty liver (NAFL) and 11 BMI-matched individuals without non-alcoholic fatty liver (CON) completed a 12-week supervised exercise training program...

BACKGROUND: Endocannabinoids are critical for rewarding behaviors such as eating, physical exercise, and social interaction. The role of endocannabinoids in mammalian sexual behavior has been suggested because of the influence of cannabinoid receptor agonists and antagonists on rodent sexual activity. However, the involvement of endocannabinoids in human sexual behavior has not been studied. AIM: To investigate plasma endocannabinoid levels before and after masturbation in healthy male and female volunteers...

Sweat is a promising biofluid scarcely used in clinical analysis despite its non-invasive sampling. A more frequent clinical use of sweat requires to know its whole composition, especially concerning to non-polar compounds, and the development of analytical strategies for its characterization. The aim of the present study was to compare different sample preparation strategies to maximize the detection of metabolites in sweat from humans collected after practicing moderate exercise. Special emphasis was put on non-polar compounds as they have received scant attention in previous studies dealing with this biofluid...

Amyotrophic Lateral Sclerosis is an adult-onset neurodegenerative disease characterized by the specific loss of motor neurons, leading to muscle paralysis and death. Although the cellular mechanisms underlying amyotrophic lateral sclerosis (ALS)-induced toxicity for motor neurons remain poorly understood, growing evidence suggest a defective energetic metabolism in skeletal muscles participating in ALS-induced motor neuron death ultimately destabilizing neuromuscular junctions. In the present study, we report that a specific exercise paradigm, based on a high intensity and amplitude swimming exercise, significantly improves glucose metabolism in ALS mice...

BACKGROUND: High-intensity intermittent training (HIIT) may serve as an effective alternative to traditional endurance training, since HIIT has been shown to induce greater improvements in aerobic fitness and health-related markers in adult populations. Our objective was to determine whether HIIT and supramaximal high-intensity intermittent training (supra-HIIT) would improve vascular structure and function in obese preadolescent boys. METHODS: Before the baseline testing, 48 obese preadolescent boys, aged 8-12 years, were randomly assigned into control (CON; n = 16), HIIT (8 × 2 minutes at 90% peak power output, n = 16), and supra-HIIT (8 × 20 seconds at 170% peak power output, n = 16) groups...
