Polycystic ovary syndrome and mitochondrial dysfunction.
Polycystic ovary syndrome and mitochondrial dysfunction. Reprod Biol Endocrinol. 2019 Aug 16;17(1):67 Authors: Zhang J, Bao Y, Zhou X, Zheng L Abstract Polycystic ovary syndrome (PCOS) is a prevalent hormonal disorder of premenopausal women worldwide and is characterized by reproductive, endocrine, and metabolic abnormalities. The clinical manifestations of PCOS include oligomenorrhea or amenorrhea, hyperandrogenism, ovarian polycystic changes, and infertility. Women with PCOS are at an increased risk of suffering from type 2 diabetes; me\tabolic syndrome; cardiovascular events, such as hypertension, dyslipidemia; gynecological diseases, including infertility, endometrial dysplasia, endometrial cancer, and ovarian malignant tumors; pregnancy complications, such as premature birth, low birthweight, and eclampsia; and emotional and mental disorders in the future. Although numerous studies have focused on PCOS, the underlying pathophysiological mechanisms of this disease remain unclear. Mitochondria play a key role in energy production, and mitochondrial dysfunction at the cellular level can affect systemic metabolic balance. The recent wide acceptance of functional mitochondrial disorders as a correlated factor of numerous diseases has led to the presupposition that abnormal mitochondrial metabolic markers are associated with PCOS. Studies conducted in the past few years have confirmed that increased oxidative stress is associated with the progression and ...
CONCLUSION: Structural prevention measures in addition to behavioral measures enable a reduction of the cancer risk caused by UV radiation. The aim must be to establish these measures nationwide for the entire population. PMID: 32494842 [PubMed - as supplied by publisher]
This study sought to determine the incidence rates of all gynecologic, including peritoneal, malignancies in the U.S. Active Duty population compared to the general US population as reported in the Surveillance, Epidemiology, and End Results Program database. MATERIALS AND METHODS: Gynecologic cancers diagnosed in U.S. Active Duty women aged 20-59 between 2004 and 2013 were retrospectively ascertained. Cancer cases were identified in both the Automated Central Tumor Registry and the Military Health System Data Repository. All cases in Automated Central Tumor Registry plus cases recorded in Military Health System Data R...

CONCLUSIONS: Our data provide new insights into the biology driving metastasis in PTCs and highlight how lncRNAs cooperate with coding transcripts to sustain these processes. PMID: 32495722 [PubMed - as supplied by publisher]
CONCLUSIONS: Fusion genes were the most common genetic cause of pediatric PTCs. Fusion gene positive PTCs showed more aggressive behavior than fusion gene negative PTCs. Several novel rearrangements were identified. Fusion genes seem to be a molecular marker number one in pediatric PTC patients. PMID: 32495721 [PubMed - as supplied by publisher]
LUNG CANCER symptoms include difficulty breathing, headaches, and persistent chest pain. But you could also be at risk of an advanced tumour if you develop a subtle sign on your eyes. Could you be at risk of lung cancer?

Conclusion: Early diagnosis and direct surgery for excision of hemangioblastoma is a good option during pregnancy while avoiding CSF diversion procedures. The symptomatic hemangioblastoma during pregnancy can be safely operated during early pregnancy. PMID: 32494398 [PubMed]
