Abstract:
... The present study investigates the effect of the addition of medicinal plants, such as lady’s mantle, lavender, rosehip, and meadowsweet, on the chemical composition, antioxidant activity, and color intensity of ready-to-drink aronia nectar during pasteurization and long-term storage. Pasteurization caused a significant decrease in anthocyanin content of aronia nectar, which reduced to 20% of the ...
... The objective of the present study was to establish whether the addition of l-carnitine (LC), which exhibits antioxidant activity, to the freezing extender improves the quality of cryopreserved Okinawan native Agu pig sperm. Ejaculated sperm frozen in an extender supplemented with 0, 1, 2.5, or 5 mM LC was thawed, and the integrities of mitochondria and the plasmalemma and other sperm characterist ...

... To date, there exists a debate on the effect of milk added to coffee infusions/beverages concerning the nutritional quality of coffee and the functional properties of its phenolic compounds. Yet, the full nutritional quality and functional properties of a coffee beverage without a significant negative impact on its sensorial profile are highly desired by the consumers. Negative/masking, positive, ...

Abstract:
... Chronic exposure of particulate matter of less than 2.5 μm (PM₂.₅) has been considered as one of the major etiologies for various respiratory diseases. Adenophora stricta Miq. is a medicinal herb that has been used for treating respiratory diseases in East Asia. The present study investigated the effect of A. stricta root extract (AsE) on PM₂.₅-induced lung injury in mice. Oral administration of 1 ...
... Plant-based proteins are very often used as carriers of different phenolic compounds. For that purpose, complexation of quercetin with almond and brown rice protein matrices was investigated. The amount of protein matrices was constant, while the concentration of quercetin varied (1 mM, 2 mM or 5 mM) during complexation. Dried complexes were investigated for quercetin amount (HPLC analysis) and an ...
... This study investigated the flavonoid content, antioxidant activity, and toxicological properties of the acetone–water fraction of stem bark of Stryphnodendron rotundifolium Mart. (TFSR). The total flavonoid content and antioxidant activity were determined, as typified by DPPH● and ABTS●⁺ radical scavenging abilities, Fe³⁺ reducing antioxidant power (FRAP), relative antioxidant capacity (RAC), and ...
... Xylooligosaccharides (XOS) are mainly derived from lignocellulosic materials, such as rice husk, corn cobs, straw, wheat bran, wheat straw and other grain by-products. XOS have become one of the functional oligosaccharides of great concern at home and abroad due to their beneficial functional properties, such as low calorie, high stability, poor digestibility and high performance in proliferating ...

Abstract:
... “Green” extraction of black alder bark using deionized water as an alternative to organic solvents and microwave (MW) - induced heating instead of convective/conductive heating was studied. An extractor of original construction with the MW capacity of 2.4 kW, equipped with a pressurized extraction chamber (V = 1350 cm³) and a condenser section, was used. The MW-assisted heating of the suspension u ...
... Systemic arterial hypertension (SAH) is a health problem of great importance worldwide, and endothelial dysfunction underlies SAH development. This condition's main characteristics include vasoconstriction, inflammation, oxidative stress, and procoagulant and proliferative states. This study's objective was to evaluate the antihypertensive, anti-inflammatory, and antioxidant effects of the whole e ...
... Effects of age on postmortem redox states were investigated in yak muscles. Extended postmortem time reduced the muscle antioxidant capacity and induced oxidation in lipids, myoglobin, and proteins. Compared with older yaks, muscles of younger ones could delay this oxidation process due to lower initial myoglobin content of 30.7%, lipid peroxidation of 42.4%, H₂O₂ of 41.2%, and intramuscular fat o ...
... This study investigated the protective effects of aged Pericarpium Citri Reticulatae ‘Chachi’ (PCR-C) on tert-butyl hydroperoxide (t-BHP)-induced oxidative damage in HepG2 cells. According to HPLC analysis, PCR-C aged 10 years (PCR-C10) had the highest flavonoids content, especially polymethoxyflavones (PMFs), compared with the fresh peel of Citrus reticulata cv. ‘Chachiensis’ and PCR-C aged 1, 3, ...
... BACKGROUND: Early‐life diseases in dairy animals are main causes of economic loss in livestock production. Oxidative stress (OS) and thyroid hormones are important inter‐related components in the normal physiology of this critical period of life.
