Research ArticleOpen accessPhrase in the titleIn vitro Kinematics Semen Tolerance to Oxidative StressCyril Mpho PilaneInterpretation of semen kinematic parameters remain as a point of discussion in predicting semen quality following processes like cryopreservation. During cryopreservation, oxidative stress remains a challenge in promoting post-thaw semen quality. Comparison of livestock semen exposed to oxidative stress, in vitro, highlight various aspects of sperm cell movement, like kinematics, to predict their qualities. Sperm cell kinematics includes the measurement … …American Journal of Animal and Veterinary Sciences, Vol. 19, Issue 3 · 13 Sep 2024 · 4,560 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleTrilobatin Possesses Protective Potentials on H2O2-Induced HepG2 Cells by Suppressing Oxidative Stress: Involvement of Nrf2/Keap1 Signal PathwayYuhan Zhai, Yuqing Zhang, Yaping Li et al.Trilobatin, a natural dihydrochalcone compound, possesses various biological activities. However, few investigations have been carried out on the mechanisms of trilobatin against oxidative stress. To comprehend the effects and mechanism of trilobatin on oxidative stress after hepatic injury, H2O2-induced HepG2 cells were used in this research. The results indicated that trilobatin enhanced the viability and improved the apoptosis morphology of … …American Journal of Biochemistry and Biotechnology, Vol. 19, Issue 4 · 22 Dec 2023 · 5,087 accessesView PDFCite

Taha et al.Traditional Coronary Artery Bypass Graft (CABG) is currently among of the chief methods in dealing with patients suffering from atherosclerotic coronary heart disease. The current study aimed to measure and compare the levels of proinflammatory cytokines and oxidative stress marker in patients who underwent multivessels Minimally Invasive Coronary Artery Bypass Graft Surgery (MICS– CABG) versus off-pump Coronary Artery Bypass Grafting … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 3 · 29 Sep 2021 · 6,170 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleEffect of Cell Phone-Emitted Electromagnetic Waves on Levels of Male Sex Hormones and Oxidative Stress Biomarkers in HumansAbdelgawad Fahmi, Amal Saad-Hussein, Khadiga S Ibrahim et al.Cell phones emit Electromagnetic Waves (EMWs) that may have adverse effects on human health. The study aimed to investigate some possible health impacts associated with cell phone-derived EMWs on male sex hormones and oxidative stress biomarkers. One-hundred recruited male volunteers were classified into two equal groups; group 1 who used mobile phones less than one hour per day for less … …OnLine Journal of Biological Sciences, Vol. 21, Issue 3 · 16 Aug 2021 · 6,822 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleThe Role of Oxidative Stress during Pregnancy on Obstetric Pathology Development in High-Yielding Dairy CowsInna Ventsova, Vladimir SafonovThe study aimed to examine the processes of oxidative stress and their intensity depending on the state of the antioxidant system in dairy cows. The study was conducted in 2018-2019 on the territory of the Druzhba breeding factory (Voronezh region, Russia) and involved 154 cows divided into 4 groups. Group 1 consisted of healthy animals (n = 83). Group 2 … …American Journal of Animal and Veterinary Sciences, Vol. 16, Issue 1 · 19 Jan 2021 · 6,723 accessesView PDFCite
Research ArticleOpen accessPhrase in the titleA Comparative Analysis on the Physiological Effects of the Physical and Chemical Properties of the Trihalomethanes on Nutrient Levels, Oxidative Stress and Sterol Compositions of Leaf Oils in Solanum Lycopersicum CultivarsBabatunde C. Akande, Olalekan S. Fatoki, James P. Odendaal et al.Trihalomethane group of disinfection by-products was used to evaluate the magnitude of physiological changes induced on nutrient levels, oxidative stress and phytosterol content in two tomato cultivars. The tomato cultivars were grown as potted plants in a greenhouse and exposed to the varying concentrations of trihalomethanes and organochlorines via irrigation water for a period of 30 days. The concentration levels … …American Journal of Agricultural and Biological Sciences, Vol. 13, Issue 1 · 11 May 2018 · 8,413 accessesView PDFCite

Research ArticleOpen accessPhrase in the titleCrosstalk between Oxidative Stress Signaling and HER2 Pathway in Breast CancerVanessa Jacob Victorino, Adriano Martin Felis Aranome, Fernanda Carolina de Campos et al.About 20% of breast cancer patients overexpress the Human Epidermal growth factor Receptor-2 (HER2), also known as ErbB2. HER2-overexpression is associated with enhanced tumor malignancy and its overexpression is related to specific target therapy against breast tumors and other cancers. HER2-mediated pathways in tumor cells act on behalf of the tumor conferring aggressive characteristics. Several reports demonstrated the occurrence of … …American Journal of Immunology, Vol. 10, Issue 4 · 17 Jan 2015 · 8,038 accessesView PDFCite
