According to the antagonistic pleiotropy theory of ageing, natural selection has favoured genes conferring short-term benefits to the organism at the cost of deterioration in later life. The 'disposable soma' theory expresses this as a life-history strategy in which somatic maintenance is below the level required to prevent ageing, thus enabling higher immediate fertility. It has been argued th...
One of the main health issues facing general practitioners in and gynecologists particular is ovarian tumors. Ovarian cancer second most prevalent malignancy female reproductive system fifth leading cause cancer-related death women. The majority instances are discovered when disease has already progressed even though early neoplasms benign which emphasizes importance detection.  ...
BACKGROUND Early detection of ovarian cancer remains a challenge due to widespread metastases and a lack of biomarkers for early-stage disease. This study was conducted to identify relevant biomarkers for both laparoscopic and serum diagnostics in ovarian cancer. METHODS Bioinformatics analysis and expression screening in ovarian cancer cell lines were employed. Selected biomarkers were furth...
To study the effects of post-stripping oocyte ageing at low temperatures on the viability of kutum (Rutilus kutum) oocytes, unfertilised eggs of five females were stored in ovarian fluid at temperatures of 4 and 7 degree centigrade for 24 hours post stripping (HPS). The stored ova of five female kutum were separately fertilised at 0 (i.e., control eggs fertilised prior to storage), 4, 8, 12, 16...
STUDY QUESTION Does maternal ageing and ovarian stimulation alter mitochondrial DNA (mtDNA) copy number and gene expression of oocytes and cumulus cells from a novel bovine model for human IVF? SUMMARY ANSWER Oocytes collected from females with identical nuclear genetics show decreased mtDNA copy number and increased expression of an endoplasmic reticulum (ER) stress gene with repect to ovari...
Ovarian cancer has received national attention as a highly virulent disease. Its lack of early warning symptoms and the failure to develop highly sensitive screening tests have led some physicians to recommend prophylactic oophorectomies to women with relatives who have had ovarian cancer. Others have recommended routine screening of otherwise normal women for CA 125, a circulating tumor marker...
Ovarian cancer is the fifth leading cause of cancer death in the United States, and contrib‐ utes significantly to the worldwide cancer burden [1]. The lack of gynecologic-specific symptoms and effective early detection methods for ovarian cancer leads to a preponder‐ ance of late-stage diagnoses. Ovarian cancer is a surgically-staged and treated disease, and the application of appropriate, gui...
introduction: women are facing inequalities including health, thus their health deserves attention. investigating people’s health status from their viewpoints is an important measure in terms of public health of society and an indicator to determine the efficiency of health system. this study aimed at evaluating the self-assessed health of older women living in shiraz and yasuj. methods: this ...
