Role of Antioxidants in Male Reproduction: Review

To counter oxidative stress, cells constitutively express enzymes that detoxify the reactive oxygen species and repair the damage. An antioxidant is any substance that when present at low concentrations compared to those of an oxidizable substrate significantly delays or prevents oxidation of that substrate. The antioxidant enzymes are major cell defense against acute oxygen toxicity. The functions of these antioxidant enzymes are to protect the membrane and cytosolic components against damage caused by free radicals. Glutathione peroxidase, Superoxide dismutase, glutathione-s-transferase, catalase, xanthine oxidase. Amongst a variety of antioxidants; vitamin E antioxidant use is essential because it travels through the body in molecules called lipoproteins and protect them from oxidation. For Many years, vitamin E considered as an anti-sterility factor. In the male reproductive system, vitamin C is known to protect spermatogenesis, and it plays a major role in semen integrity and fertility in men. It increases testosterone levels and prevents sperm agglutination. It is an important chain-breaking antioxidant, contributing up to 65 % of the total antioxidant capacity of seminal plasma found intracellularly and extracellularly. N-Acetyl cysteine reacts with highly oxidizing radicals such as ˙OH, ˙NO2, CO3˙‑, and also bind redox-active metal ions. Thiosl can also afford radioprotection through the donation of reducing equivalents. Keywords: Antioxidants; Male fertility; Sperm quality

EFFECT OF STRESS ON HISTOPATHOLOGY OF MALE REPRODUCTIVE SYSTEM IN RATS

Background: Although relatively little is known about factors affecting fertility. Latest literature suggests that environmental and lifestyle factors play an important role. Recently, oxidative stress has become the focus of interest as potential cause of male infertility. Oxidative stress may play a role in a number of conditions known to be detrimental to male fertility Method: Adult male albino rats weighing 200 - 220 g and aged 12-15 weeks male rats were selected for the study. The rats were randomly analyzed into 3 groups Group 1: Control rat, Group 2: Swimming stress without treatment, Group 3: Treated with vitamin C 30mg/kg/day doses. All rats were subjected to swimming stress daily between 9.00 AM to 10.00 AM until 50 days. Drugs were administered orally for 50 days half an hour before subjecting to stress. At end of the study the reproductive organs testes, seminal vesicles, Vas deferens and prostate were dissected and the samples were used for the histo-pathological evaluation. Result: In stress group section of testis shows seminiferous tubules showed focial poor spermatogenesis with reduction in number of sperm containing seminiferous tubules and absence of spermatozoa was clearly recognized in some seminiferous tubules. Treatment with antioxidant showed recovery but still some of the seminiferous tubules showed decreased spermatozoa. Stress changes in seminal vesicle: the hyperplasia of epithelial lining, histological features of mucosa severely affected and reduced number of gland. Stress induced changes in vas deferens: produced desquamated ling epithelium with atrophic changes and mild exploited epithelium, degenerated basement membrane of vas deferens. Stress induced changes in prostate: Prostatic acini with many papillary folds, desquamated epithelial cells, epithelial proliferation was seen. Conclusion: Oxidative stress produced deleterious effects on male reproductive system and supplementation of antioxidants such as vitamin C have been shown to be protecting effect against the histological changes produced by the oxidative stress on male reproductive system in rats.KEYWORDS:  Stress; Male reproductive organs; Histopathology; Rat

Correlation of primary knee osteoarthritis severity with the lipid peroxidation biomarker (MDA) in synovial fluid: A pilot study

Introduction: Osteoarthritis (OA) is progressive, degenerative disease that leads to joint pain, tenderness, stiffness, locking, effusion, reduced motion, swelling, crepitus, and disability. The pain in OA is the most significant clinical feature and impacts function, mobility, quality of life, and reason for medical advice. Methods: A hospital-based cross-sectional study was conducted on patients attending the Outpatient Department of Orthopedics. A total of 50 individuals with primary knee osteoarthritis in the age range of 45-90 years were chosen at random for the research (26 females and 24 males). The American College of Rheumatology's Diagnostic criteria were employed to diagnose osteoarthritis, and a visual analogue scale was utilized to score the severity of pain. Knee OA was graded using the Kellgren-Lawrence (K-L) radiographic assessment method. The MDA levels in the synovial fluid of all 50 individuals were measured by using the Thiobarbituric acid technique. The severity of knee OA was compared to oxidative stress measures and synovial fluid MDA levels in order to determine if there was a link between oxidative stress-induced damage and disease development. Results: Grades 1, 2, 3, and 4 have MDA values of 3.9±0.4, 4.3±0.5, 5.4±0.2 and 5.96±0.2, respectively, in synovial fluid. MDA mean levels in synovial fluid increased with the severity of knee osteoarthritis (K-L grading), which was statistically significant (p.001). Conclusions: Kellgren-Lawrence grading and synovial MDA had a favourable connection. In osteoarthritis patients, free radical-induced lipid peroxidation was high, as evaluated by synovial fluid MDA concentration, and it increased with the severity of osteoarthritis. It suggests that oxidative stress is important in the etiopathogenesis of OA and that synovial MDA could be employed as a biomarker to determine the severity of the illness

Evaluation of Short-Term Side Effects Following the First Dose of COVID-19 Vaccines Among Physicians and Dentists: A Cross-Sectional Study from India

Background: Efficacy and safety are fundamental for the development of successful COVID-19 vaccines. Vaccine-associated side effects influence vaccine hesitancy. This study investigated the prevalence, severity, and onset of side effects following the first dose of COVID-19 vaccines among physicians and dentists working in various healthcare settings across India. Methods: A cross-sectional survey collected self-report data from April to June 2021 on side effects following the first dose of the vaccine. An online validated questionnaire using the Google Docs® platform was circulated via email and social media platforms. Results: More than 40% of participants experienced at least one side effect after the first dose of vaccination; the most common were mild and resolved within three days after vaccination. More than 91% of respondents received the Covishield (AstraZeneca) vaccine; the most prevalent adverse effects were soreness of the injected arm (78.9%), tiredness (71.1%), and fever (54.9%). Logistic regression showed that women were almost 60% less likely to report side effects. Conclusion: Findings supported the safety of the first dose of the COVID-19 vaccine based on relatively few self-limiting side effects, mainly soreness of the injected arm and tiredness. Further research is needed to determine the long-term safety of COVID-19 vaccines, especially after booster doses

Self-reported side effects of COVID-19 vaccines among health professions students in India

Studies focusing on the safety and common side effects of vaccines play a crucial role in enhancing public acceptance of vaccination. Research is scarce regarding the usage of COVID-19 vaccines and the side effects experienced by health professions students in India and other countries. This study aimed to document self-reported side effects associated with COVID-19 vaccination among medical and dental students of six medical and dental colleges and teaching hospitals in four states (Tamil Nadu, Madhya Pradesh, Gujarat, and West Bengal) of India. A cross-sectional survey using purposive sampling of medical and dental students was conducted from 26 April to 26 May 2021. Data was collected using a Google Forms questionnaire capturing information regarding receiving COVID-19 vaccines, side effects and symptoms, onset and duration of symptoms, use of treatment to alleviate symptoms, awareness of haematologic risks associated with vaccination, and side effects from previous (non-COVID-19) vaccinations. The majority (94.5%) of participants received both doses of the Covishield/AstraZeneca COVID-19 vaccine. Among participants (n = 492), 45.3% (n = 223) reported one or more side effects. The most frequently reported side effects were soreness of the injected arm (80.3%), tiredness (78.5%), fever (71.3%), headache (64.1%), and hypersomnia (58.7%). The two most common severe symptoms were fever (14.8%) and headache (13%). Most side effects appeared on the day of vaccination: soreness of the injection site (57%), fever (43.1%), and tiredness (42.6%). Most reported symptoms persisted for one to three days–soreness of the injection site (53%), fever (47.1%), and headache (42.6%). Logistic regression showed that women were almost 85% less likely to report side effects. The study’s findings corroborate the safety of the Covishield/AstraZeneca vaccine’s first dose, evidenced by the relatively minor and transient nature of the side effects. However, the study underscores the necessity for ongoing research to assess the long-term impacts of COVID-19 vaccines, especially in the context of booster doses, thereby contributing to the global understanding of vaccine safety and efficacy
