It is known that hypoxia has a negative effect on nervous system functions, but exercise and DHA (docosahexaenoic acid) have positive effect. In this study, it was investigated whether exercise and/or DHA can prevent the effects of hypoxia on EEG and nerve conduction velocity (NCV). 35 adult Wistar albino male rats were divided into five groups (n=7): control (C), hypoxia (H), hypoxia and exercise (HE), hypoxia and DHA (HD), and hypoxia and exercise and DHA (HED) groups. During the 28-day hypoxia exposure, the HE and HED groups of rats were exercised (0% incline, 30 m/min speed, 20 min/day, 5 days a week). In addition, DHA (36 mg/kg/day) was given by oral gavage to rats in the HD and HED groups. While EEG records were taken before and after the experimental period, NCV records were taken after the experimental period from anesthetized rats. Data were analyzed by paired t-test, one-way ANOVA, and post hoc Tukey test. In this study, it was shown that exposure to hypoxia decreased theta activity and NCV, but exercise and DHA reduced the delta activity, while theta, alpha, beta activities, and NCV were increased. These results have shown that the effects of hypoxia exposure on EEG and NCV can be prevented by exercise and/or DHA.

A convenient but efficient tool for evaluating dietary intakes in Chinese professional athletes has yet to be established. The aim of this study was to assess the validity of a short semi-quantitative food frequency questionnaire (FFQ) through comparison with 3-day weighed food records (3DWFRs) and corresponding serum biomarkers from a cohort of 102 professional athletes, while also evaluating its reproducibility. The relative validity was assessed using Spearman correlation coefficients, cross-quintiles classification, weighted kappa, and Bland-Altman analysis, while reproducibility was evaluated using the Spearman correlation coefficients and intraclass correlation coefficient (ICC) between two FFQs.

Background & Aims: Muscle strength is a key predictor of both quality of life and mortality. Although numerous studies have investigated the relationship between omega-3 (ω-3) intake and muscle strength, the evidence remains inconclusive. Furthermore, it is unclear whether this association is influenced by protein intake.

Vitiligo, a prevalent cutaneous depigmentation disorder, often leads individuals to seek cosmetic remedies such as dihydroxyacetone (DHA)-infused camouflage makeup. Wood's lamp, a common diagnostic tool in dermatology, is typically employed to assess vitiligo lesions, revealing DHA-induced fluorescence in a distinct salmon color, contrasting with the bright blue-white fluorescence exhibited by vitiligo lesions. Erythrasma, a bacterial infection of the epidermis, is known for its unique bright coral-pink or coral-red fluorescence under Wood's lamp.

Preterm birth (delivery prior to 37 weeks) appears to be rising globally, increasing the risk of a myriad of down-stream disorders which affect families, their offspring and society, including increased morbidity, mortality and economic costs. Strategies for prevention of preterm birth have therefore become a priority among healthcare providers. One proposed strategy is increased consumption of Omega-3 long-chain polyunsaturated fatty acids (LC-PUFAs), particularly docosahexaenoic acid (DHA) (from food or supplements) in women of childbearing age and during pregnancy.

Metabolic dysfunction-associated steatotic liver disease (MASLD) has emerged as a public health threat as it affects approximately 38% of the adult population worldwide, with its prevalence rising in step with that of obesity and type 2 diabetes. Beyond the implications of MASLD for liver health, it is also associated with cardiovascular and vascular dysfunction. Although the many shared risk factors and common metabolic milieu might indicate that cardiovascular disease and MASLD are discrete outcomes from common systemic pathogeneses, a growing body of evidence has identified a potential causal relationship between MASLD and coronary artery disease, which is the leading cause of morbidity and mortality in people with MASLD and all-cause mortality worldwide.
