The purpose of this study was to evaluate the effect of docosahexaenoic acid (DHA) dietary supplementation on semen quality, fatty acid composition, antioxidant capacity, and DNA fragmentation. In this randomized, double blind, placebo-controlled, parallel-group study, 74 subjects were recruited and randomly assigned to either the placebo group (n=32) or to the DHA group (n=42) to consume three 500-mg capsules of oil per day over 10 weeks. The placebo group received 1,500 mg/day of sunflower oil and the DHA group 1,500 mg/day of DHA-enriched oil. Seminal parameters (semen volume, sperm concentration, motility, morphology, and vitality), total antioxidant capacity, deoxyribonucleic acid fragmentation, and lipid composition were evaluated prior to the treatment and after 10 weeks. Finally, 57 subjects were included in the study with 25 in the placebo group and 32 in the DHA group. No differences were found in traditional sperm parameters or lipid composition of the sperm membrane after treatment. However, an increase in DHA and Omega-3 fatty acid content in seminal plasma, an improvement in antioxidant status, and a reduction in the percentage of spermatozoa with deoxyribonucleic acid damage were observed in the DHA group after 10 weeks of treatment.

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.

The rising popularity of bioconjugate therapeutics has led to growing interest in late-stage functionalization (LSF) of peptide scaffolds. α,β-Unsaturated amino acids like dehydroalanine (Dha) derivatives have emerged as particularly useful structures, as the electron-deficient olefin moiety can engage in late-stage functionalization reactions, like a Giese-type reaction. Cheap and widely available building blocks like organohalides can be converted into alkyl radicals by means of photoinduced silane-mediated halogen-atom transfer (XAT) to offer a mild and straightforward methodology of alkylation.

The detection of endogenous anabolic androgenic steroids misuse in Asian population using the Steroidal Module of the Athlete Biological Passport (ABP) is a challenge due to the high prevalence of UGT2B17 gene deletion polymorphism with low levels of testosterone (T) glucuronide. In this study, the capabilities of different approaches based on urine analysis for the detection of oral T undecanoate administration were evaluated in 13 Asian volunteers, including 11 subjects with del/del genotype and 2 subjects with del/ins genotype. In the first part of the work, the effect on the urinary steroid profile (SP) and on the isotope ratio mass spectrometry markers was evaluated.

Objective: This study explored the association between ω-6 to ω-3 polyunsaturated fatty acids (PUFAs) and metabolic syndrome in women experiencing climacteric syndrome.
Methods: The study involved 186 female participants and utilized surveys, anthropometric measurements (waist circumference, height, BMI, waist-to-height ratio), blood pressure assessments, and blood samples for lipid profile, glucose, insulin, HbA1c analysis. Serum PUFAs levels were analyzed using gas chromatography-mass spectrometry.

Dihydroartemisinin (DHA) is an effective antimalarial drug with potential antitumor efficacy, yet toxicological information is limited. The present study was designed to evaluate the potential toxicity of oral DHA. DHA was administered orally by gavage to SD rats at doses of 0, 25, 50, and 75/60 mg/kg b.
