    The Best Whey Protein Powder Selection Via Vikor Based on Circular Intuitionistic Fuzzy Sets
    (Mdpi, 2023) Buyukselcuk, Elif Caloglu; Sari, Yigit Can; Çaloğlu Büyükselçuk, Elif
    People try very hard to have a symmetrical, strong, and beautiful body. The human body needs high amino acids for muscle protein synthesis. Whey protein is a good choice that contains all amino acids, which increases muscle protein synthesis and improves body shape with resistance exercise. For this reason, those who do sports, especially professionals, prefer to use these products frequently. A large number of commercial whey protein powders are sold on the market, and to achieve maximum purpose, individuals want to use the best one. Intuitionistic fuzzy sets are used in order to minimize the negative effects of the uncertainty environment and ambiguous information encountered in the decision-making process on the solution. In this study, VIKOR, based on the circular intuitionistic fuzzy set, has been used to determine the best whey protein supplement. In line with the comprehensive literature review and expert opinions, the evaluation criteria affecting the selection process have been determined, and the solution of the problem has been focused.

    The Effect of Whey Proteins on the Brain and Small Intestine Nitric Oxide Levels: Protein Profiles in Methotrexate-Induced Oxidative Stress

    Objectives: The aim of this study was to determine the effects of whey proteins on methotrexate (MTX)-induced brain and small intestine damage. Materials and Methods: 30 Sprague Dawley rats (200-300 g) were divided into four groups: Control, control + whey, MTX, and MTX+whey. MTX was administered at 20 mg/kg (single dose) intraperitoneally to the MTX group rats, and 2 mg/kg of whey protein were administered by oral gavage for 10 days to the whey groups. Lipid peroxidation, glutathione, and nitric oxide (NO) levels, as well as glutathione-Stransferase and superoxide dismutase activities were measured in the brain and small intestine. SDS-polyacrylamide gel electrophoresis of the brain and intestine tissues were also carried out. Results: While MTX treatment caused oxidative damage in the brain and small intestine, whey protein administration ameliorated MTXinduced oxidative stress. MTX administration did not change the brain's NO level, while an increase in intestinal NO level was detected. Conclusion: MTX induced oxidative stress in the brain and small intestine changed the protein metabolism in these tissues regardless of reduced food intake. Consecutive 10-day administration of whey proteins has shown its therapeutic effect on MTX-induced brain and small intestine oxidative damage.
