Dietary supplementation of barley and/or dates attenuate hypercholesterolemic-induced endometrial dysfunction in Wistar albino rats via alleviation of apoptotic pathways and enhancing oxidative capacity

Abnormal Endometrial Receptivity and Oxidative Stress in Polycystic Ovary Syndrome

Polycystic ovary syndrome (PCOS) is a common endocrine and metabolic disorder in women of childbearing age. Individual heterogeneity is evident, and the prevalence rate ranges between 6 and 15% globally. The prevalence rate of PCOS in Chinese women of childbearing age is 5.6%. The main manifestations are infertility, sparse menstruation, irregular vaginal bleeding, long-term endometrial hyperplasia, and endometrial cancer. PCOS is often associated with hyperandrogenemia, insulin resistance, hyperinsulinemia, obesity, metabolic syndrome, and intestinal flora disorder. Although there have been many studies in the past, the underlying pathophysiological mechanism of the disease is still unclear. Studies have shown that PCOS diseases and related complications are closely related to local oxidative stress imbalance in the endometrium, leading to poor endometrial receptivity and effects on pregnancy. Previous reviews have mainly focused on the abnormal mechanism of ovarian oxidative stress in women with PCOS, while reviews on endometrial receptivity and oxidative stress are relatively insufficient. This study reviews the abnormal cellular and molecular mechanisms of oxidative stress due to comorbidities in women with PCOS, leading to a downregulation of endometrial receptivity.

The potential antioxidant bioactivity of date palm fruit against gentamicin-mediated hepato-renal injury in male albino rats

Gentamicin (GM) is a commonly prescribed antimicrobial drug used for treatment of infections but associated hepatic and renal complications restrict its efficacy. Overproduction of free radicals and inflammation are involved in GM-induced hepato-renal damage. Date palm is renowned to have antioxidant and anti-inflammatory bioactive composites. In this context, the current research was purposed to assess the ameliorative influence of date palm extract (DE) supplementation against GM-induced hepato-renal injury. Gas chromatography-mass spectrometry (GC-MS) was used to detect the bioactive constitutes in DE. The protective action of high and low doses of DE was assessed alongside the GM remediation (80 mg/kg) in rats. GM evoked significant alterations in liver and kidney function biomarkers (aminotransferases, albumin, creatinine, and blood urea). Furthermore, notable elevations in malondialdehyde (MDA) level and increment expression of inducible nitric oxide synthase (iNOS) along with reduction in catalase (CAT) activity were observed in both organs after GM treatment. Oxidative stress was the main modulatory mechanism in GM-induced hepato-renal toxicity. However, DE could mitigate the GM-inflicted liver and kidney damage, in a dose-response pattern, due to its high content of phenolics and flavonoids.

Female infertility and herbal medicine: An overview of the new findings

Infertility is defined as the failure to achieve a successful pregnancy after 12 months' sexual activity that affects 15%-17% of couples in the world and about 50% of them are related to female infertility factors. In this study, using the PRISMA checklist and MeSH keywords, 128 articles were extracted from various databases (PubMed, Cochrane library, WHO, Iranmedex, Science Direct, SID, and Google Scholar search engine) without language and time restrictions, and 128 articles were selected after eliminating duplicate studies. In this review, we present some solid evidence for role of herbal medicine in the treatment of female infertility. The results of this study showed that different parts of some plants are rich in polyphenolic compounds (isoflavones and flavonoids) and other compounds which are beneficial to in reproductive health in women. The compounds in these plants, along with regulating the female endocrine pathways, and improving symptoms of menopause, treat female reproductive disorders such as polycystic ovary syndrome (PCOS), premature ovarian failure (POF), endometriosis, hyperprolactinemia, and hypothalamic dysfunction; moreover, because of their anticancer, antioxidant, and antidepressant properties, they can be used in traditional medicine or in the pharmaceutical industry as safe compounds in women's health.
