The aim: To study the morphological structure of the parotid salivary gland of young, mature and old rats at micro- and ultrastructural levels under water deprivation. PATIENTS AND METHODS: Materials and methods: The experiment was carried out on thirty six laboratory male rats of different ages (young, mature and old). The rats of the control group received normal volume of drinking water...

PURPOSE: To evaluate the prevalence of regional lymph node (LN) metastasis in patients with non-clear cell epithelial ovarian cancer apparently confined to the ovary, stratified by tumor grade. METHODS: The National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) database was accessed (1988-2014). We identified patients with epithelial ovarian carcinoma of serous, endometrioid and mucinous histology apparently confined to the ovary who underwent extensive lymphadenectomy (defined as at least 20 lymph nodes removed)...

Cancer metastatic spread to serous cavity causes malignant pleural effusions (MPEs), indicating dismal prognosis. Tumor microenvironment can implement suppressive activity on host immune responses. Thus, we investigated the prevalence of Tregs and the relationship between them and TGF- β and IL-10 concentrations and measured expression of FOXP3 , CTLA-4 , CD28 , and GITR genes, as well as protein expression of selected genes in benign effusions and MPEs. The percentage of Tregs was determined by means of multicolor flow cytometry system...

AIM: To explore the expression profile of some DHRS genes in high-grade serous ovarian cancer (SOVC) and to study their prognostic values. PATIENTS & METHODS: A retrospective bioinformatic analysis was performed using data in the Gene Expression Omnibus, the Human Protein Atlas and the Cancer Genome Atlas-Ovarian Cancer. RESULTS: Increased DHRS12 expression was an independent indicator of poor overall survival (hazard ratio [HR]: 1.265; 95% CI: 1...

Somatic mutations in TP53 are a hallmark of high-grade serous ovarian cancer (HGSOC), although their prognostic and predictive value as markers is not well defined. Next-generation sequencing (NGS) can identify novel mutations with high sensitivity, that may be repurposed as potential druggable anti-cancer targets and aid in therapeutic decisions. Here, a commercial NGS cancer panel comprising 26 genes, including TP53 , was used to identify new genetic markers of platinum resistance and patient prognosis in a retrospective set of patients diagnosed with epithelial ovarian cancer...

Epithelial ovarian cancer (EOC) is a lethal gynaecological disease that imposes significant burden on health care and patient quality of life. High-grade serous carcinoma of the ovary (HGSC) is the most prevalent histological type of EOC. A vast majority of HGSC cases are diagnosed at late stages of the disease, limiting the opportunity for clinical intervention and resulting in a 10-year survival rate of <20%. Recent innovations in high-throughput molecular analysis of patient-derived specimens may address these clinical challenges by providing an enhanced understanding of the molecular aetiology of ovarian cancer, in addition to offering several opportunities for rational biomarker and targeted therapy discovery...

New techniques able to monitor the maturation of tissue engineered constructs over time are needed for a more efficient control of developmental parameters. Here, a label-free fluorescence lifetime imaging (FLIm) approach implemented through a single fiber-optic interface is reported for non-destructive in situ assessment of vascular biomaterials. Recellularization processes of antigen removed bovine pericardium scaffolds with endothelial cells and mesenchymal stem cells were evaluated on the serous and the fibrous sides of the scaffolds, two distinct extracellular matrix niches, over the course of a 7 day culture period...

Purpose: Optic disc pits (ODP) are rare and congenital anomalies of the optic disc, sometimes remaining asymptomatic. However, serous macular detachment or optic disc maculopathy is the most common complication, causing significant visual deterioration, without a current consensus about treatment. We describe a case of ODP maculopathy that was treated successfully with micropulse laser. Observations: A patient with ODP maculopathy remained with macular serous detachment after nine months of follow up after pars plana vitrectomy...

Objective: The main aim of this study was to evaluate cancer antigen 125 (CA125)/carcinoembryonic antigen (CEA) ratio (CCR), as a reliable marker to differentiate ovarian mucinous carcinoma from other epithelial ovarian carcinomas (EOCs), namely serous, clear cell, and endometrioid carcinomas. Methods: Female patients suffering from different kinds of EOCs whom were subjected to elective surgery at the Gangnam Severance Hospital between January 2008 and December 2016, were included in this study...

Objective: Circulating cell-free tumor DNA (cfDNA) is the DNA released by apoptotic and necrotic cells of the primary tumor into the blood during the period of tumor development. The cfDNA reflects the genetic and epigenetic alterations of the original tumor. TP53 mutations are a defining feature of high-grade serous ovarian carcinoma. We optimized the methods for detecting TP53 mutations in cfDNA from blood samples. We confirmed the correlation of TP53 mutation in primary ovarian cancer tissue and it in cfDNA using digital polymerase chain reaction (dPCR)...

Autoantibodies against myelin oligodendrocyte glycoprotein (MOG-IgG) have been detected in inflammatory demyelinating central nervous system diseases. A 30-year-old woman had blurred vision, marked optic nerve disc swelling, serous retinal detachment at the macular on optic coherence tomography, and MOG-IgG seropositivity. The patient was thought to have optic papillitis associated with MOG-IgG. Her symptoms rapidly improved after high-dose methylprednisolone therapy. We hypothesize that serous retinal detachment was secondary, arising from optic papillitis...

Ovarian cancer as the most fatal gynecological malignancy is often manifested by excessive fluid accumulation known as ascites or effusion. Ascites-derived microRNAs (miRNAs) may be closely associated with ovarian cancer progression. However, our knowledge of their roles, altered expression, and clinical outcomes remained limited. In this study, large-scale expression profiling of 754 human miRNAs was performed using real-time quantitative polymerase chain reaction and 384-well TaqMan array human miRNA A and B cards to identify differentially expressed miRNAs between extracellular fraction of the ascitic fluid associated with high-grade serous ovarian carcinomas and control plasma...

DNA methylation is one of the epigenetic mechanisms associated with gene expression and plays a key role as in activation and deactivation of oncogenes and tumor suppressor genes, respectively. This study employed DNA methylation array to identify methylated genes which are highly correlated with various phenotypes of epithelial ovarian cancer (EOC) in Thai patients and to quantify promoter CpG-island methylation of candidate genes. Tissues from patients with serous and non-serous EOC showed significantly higher promoter methylation of EGFL7 and RASSF1 compared to benign cases...

OBJECTIVE: To evaluate the frequency of central serous chorioretinopathy (CSC) in African Americans/blacks within an academic center in a predominantly African American city, as the current belief is that CSC is rare in this population. METHODS: A retrospective review of all patients' charts diagnosed with CSC at Wilmer Eye Institute/Johns Hopkins University from August 2009-August 2015 was conducted via an electronic health record search (EPIC). The charts were categorized by self-reported race and gender...
