Palmitoylethanolamide in Postmenopausal Metabolic Syndrome: Current Evidence and Clinical Perspectives.

Menopause leads to a decline in estrogen levels, resulting in significant metabolic alterations that increase the risk of developing metabolic syndrome-a cluster of conditions including central obesity, insulin resistance, dyslipidemia, and hypertension. Traditional interventions such as hormone replacement therapy carry potential adverse effects, and lifestyle modifications alone may not suffice for all women. This review explores the potential role of palmitoylethanolamide (PEA), an endogenous fatty acid amide, in managing metabolic syndrome during the postmenopausal period.

Carotenoid Interactions with PCSK9: Exploring Novel Cholesterol-Lowering Strategies.

: This study investigated the potential of green algae-derived carotenoids as natural inhibitors of the proprotein convertase subtilisin/kexin type 9 (PCSK9), a key regulator of cholesterol metabolism. PCSK9 promotes the degradation of low-density lipoprotein receptors (LDLR), thereby increasing blood cholesterol levels and elevating the risk of cardiovascular diseases. /: We screened the pharmacophore fit score of 27 carotenoids with PCSK9 and identified 14 that were analyzed for binding affinity and molecular interactions.

Computational Assessment of Carotenoids as Keap1-Nrf2 Protein-Protein Interaction Inhibitors: Implications for Antioxidant Strategies.

The Keap1-Nrf2 pathway is an essential system that maintains redox homeostasis and modulates key metabolic processes, including metabolism of amino acids to promote the synthesis of antioxidant enzymes. Inhibitors of the protein-protein interaction (PPI) between Keap1 and Nrf2 have emerged as a promising strategy for developing novel classes of antioxidant agents that selectively activate this pathway without off-target effects. Carotenoids, a large family of lipophilic isoprenoids synthesized by all photosynthetic organisms, are well-known for their antioxidant activities.

Effects of Maltodextrin-Fructose Supplementation on Inflammatory Biomarkers and Lipidomic Profile Following Endurance Running: A Randomized Placebo-Controlled Cross-Over Trial.

Background: Managing metabolism for optimal training, performance, and recovery in medium-to-high-level endurance runners involves enhancing energy systems through strategic nutrient intake. Optimal carbohydrate intake before, during, and after endurance running can enhance glycogen stores and maintain optimal blood glucose levels, influencing various physiological responses and adaptations, including transitory post-endurance inflammation. This randomized trial investigates the impact of a high-dose 2:1 maltodextrin-fructose supplementation to medium-to-high-level endurance runners immediately before, during, and after a 15 km run at 90% VO intensity on post-exercise inflammatory stress.
