Ultrasonography in the Differentiation of Endometriomas from Hemorrhagic Ovarian Cysts: The Role of Texture Analysis.

J Pers Med 2021 Jun 28;11(7). Epub 2021 Jun 28.

Radiology and Imaging Department, County Emergency Hospital, Cluj-Napoca, Clinicilor Street, Number 5, 400006 Cluj-Napoca, Romania.

The ultrasonographic (US) features of endometriomas and hemorrhagic ovarian cysts (HOCs) are often overlapping. With the emergence of new computer-aided diagnosis techniques, this is the first study to investigate whether texture analysis (TA) could improve the discrimination between the two lesions in comparison with classic US evaluation. Fifty-six ovarian cysts (endometriomas, 30; HOCs, 26) were retrospectively included. Read More

Occurrence of Zearalenone and Its Metabolites in the Blood of High-Yielding Dairy Cows at Selected Collection Sites in Various Disease States.

Toxins (Basel) 2021 06 28;13(7). Epub 2021 Jun 28.

Department of Veterinary Prevention and Feed Hygiene, Faculty of Veterinary Medicine, University of Warmia and Mazury in Olsztyn, Oczapowskiego 13, 10-718 Olsztyn, Poland.

Zearalenone (ZEN) and its metabolites, alpha-zearalenol (α-ZEL) and beta-zearalenol (-ZEL), are ubiquitous in plant materials used as feed components in dairy cattle diets. The aim of this study was to confirm the occurrence of ZEN and its selected metabolites in blood samples collected from different sites in the hepatic portal system (posthepatic-external jugular vein EJV; prehepatic-abdominal subcutaneous vein ASV and median caudal vein MCV) of dairy cows diagnosed with mastitis, ovarian cysts and pyometra. The presence of mycotoxins in the blood plasma was determined with the use of combined separation methods involving immunoaffinity columns, a liquid chromatography system and a mass spectrometry system.

Probing the tumorigenic potential of genetic interactions reconstituted in murine fallopian tube organoids.

J Pathol 2021 Jun 29. Epub 2021 Jun 29.

Department of Molecular Carcinogenesis, Chiba Cancer Center Research Institute, Chiba, Japan.

Genetically engineered mice have been the gold standard in modeling tumor development. Recent studies have demonstrated that genetically engineered organoids can develop subcutaneous tumors in immunocompromised mice, at least for organs that prefer predominant driver mutations for tumorigenesis. To further substantiate this concept, the fallopian tube (FT), a major cell of origin of ovarian high-grade serous carcinoma (HGSC), which almost invariably carries TP53 mutations, was investigated for p53 inactivation-driven tumorigenesis.

Mod Pathol 2021 Jun 25. Epub 2021 Jun 25.

Department of Obstetrics and Gynecology, Kindai University Faculty of Medicine, Osaka, Japan.

Recent studies have reported cancer-associated mutations in normal endometrium. Mutations in eutopic endometrium may lead to endometriosis and endometriosis-associated ovarian cancer. We investigated PIK3CA mutations (PIK3CAm) for three hotspots (E542K, E545K, H1047R) in eutopic endometrium in patients with ovarian cancer and endometriosis from formalin-fixed paraffin-embedded specimens by laser-capture microdissection and droplet digital PCR.

A wide spectrum of hereditary syndromes predispose patients to distinct pancreatic abnormalities, including cystic lesions, recurrent pancreatitis, ductal adenocarcinoma, nonductal neoplasms, and parenchymal iron deposition. While pancreatic exocrine insufficiency and recurrent pancreatitis are common manifestations in cystic fibrosis and hereditary pancreatitis, pancreatic cysts are seen in von Hippel-Lindau disease, cystic fibrosis, autosomal dominant polycystic kidney disease, and McCune-Albright syndrome. Ductal adenocarcinoma can be seen in many syndromes, including Peutz-Jeghers syndrome, familial atypical multiple mole melanoma syndrome, Lynch syndrome, hereditary breast and ovarian cancer syndrome, Li-Fraumeni syndrome, and familial pancreatic cancer syndrome.

STING pathway expression in low-grade serous carcinoma of the ovary: an unexpected therapeutic opportunity?

J Pathol Clin Res 2021 Jun 17. Epub 2021 Jun 17.

Department of Molecular Oncology, BC Cancer Research Center, Vancouver, BC, Canada.

Ovarian carcinoma histotypes are distinct diseases with variable clinical outcomes and response to treatment. There is a need for new subtype-specific treatment modalities, especially for women with widespread and chemo-resistant disease. Stimulator of interferon genes (STING) is a part of the cGAS-STING pathway that mediates innate immune defence against infectious DNA-containing pathogens and also detects tumour-derived DNA and generates intrinsic antitumour immunity.

Remarks on the Hormonal Background of the Male Equivalent of Polycystic Ovary Syndrome.

Prague Med Rep 2021 ;122(2):73-79

Institute of Endocrinology, Prague, Czech Republic.

The hypothesis that the most common female endocrine disease, the polycystic ovarian syndrome (PCOS), has a male equivalent, has recently become more widely accepted. The male form of PCOS is marked by alterations in the secretion of gonadotropins, increased insulin resistance, and changes of the levels of several steroid hormones, with clinical manifestations including premature androgenic alopecia (AGA). Because these symptoms are not always found in men with genetic predispositions, knowledge of the male equivalent of PCOS needs to be supplemented by measurements of adrenal 11-oxygenated C19 steroids, particularly 11-keto-, and 11β-hydroxy-derivatives of testosterone and dihydrotestosterone, by focusing on the newly-realized role of skin as an endocrine organ, and by confirming any age-related factors in glucose metabolism disorders in such predisposed men.

Association of Angiotensin-Converting Enzyme gene polymorphism in Pakistani women with the atypical steroidogenesis in Polycystic ovarian syndrome: A case-control study.

Saudi J Biol Sci 2021 Jun 14;28(6):3483-3489. Epub 2021 Mar 14.

Department of Microbiology and Molecular Genetics, University of the Punjab, Lahore, Pakistan.

Background: Polymorphism in the angiotensin-converting enzyme gene (ACE) is responsible for elevated ACE concentrations in plasma. High ACE levels induce insulin resistance and hyperandrogenism, which are the main attributes of polycystic ovary syndrome (PCOS). Therefore, it was hypothesized that I/D polymorphism plays a role in the pathogenesis of PCOS. Read More
