Identification of 12 new susceptibility loci for different histotypes of epithelial ovarian cancer

Abstract: To identify common alleles associated with different histotypes of epithelial ovarian cancer (EOC), we pooled data from multiple genome-wide genotyping projects totaling 25,509 EOC cases and 40,941 controls. We identified nine new susceptibility loci for different EOC histotypes: six for serous EOC histotypes (3q28, 4q32.3, 8q21.11, 10q24.33, 18q11.2 and 22q12.1), two for mucinous EOC (3q22.3 and 9q31.1) and one for endometrioid EOC (5q12.3). We then performed meta-analysis on the results for high-grade serous ovarian cancer with the results from analysis of 31,448 BRCA1 and BRCA2 mutation carriers, including 3,887 mutation carriers with EOC. This identified three additional susceptibility loci at 2q13, 8q24.1 and 12q24.31. Integrated analyses of genes and regulatory biofeatures at each locus predicted candidate susceptibility genes, including OBFC1, a new candidate susceptibility gene for low-grade and borderline serous EOC.

Super-Resolution Structured Illumination Microscopy.

Abstract: Super-resolved structured illumination microscopy (SR-SIM) is among the most rapidly growing fluorescence microscopy techniques that can surpass the optical diffraction limit. The strength of SR-SIM is that it can be readily applied to samples prepared for conventional fluorescence microscopy, requiring no sophisticated sample preparation protocols. As an extension of wide-field fluorescence microscopy, it is inherently capable of multicolor imaging and optical sectioning and, with sufficiently fast implementations, permits live cell imaging. Image reconstruction, however, currently relies on sophisticated computational procedures, susceptible to reconstruction artifacts, requiring trained users to recognize and avoid them. Here, we review the latest developments in SR-SIM research. Starting from a historical overview of the development of SR-SIM, we review how this method can be implemented in various experimental schemes, we provide an overview of the important parameters involved in successful image re...

An Aqueous Redox-Flow Battery with High Capacity and Power: The TEMPTMA/MV System.

Abstract: Redox-flow batteries (RFB) can easily store large amounts of electric energy and thereby mitigate the fluctuating output of renewable power plants. They are widely discussed as energy-storage solutions for wind and solar farms to improve the stability of the electrical grid. Most common RFB concepts are based on strongly acidic metal-salt solutions or poorly performing organics. Herein we present a battery which employs the highly soluble N,N,N-2,2,6,6-heptamethylpiperidinyl oxy-4-ammonium chloride (TEMPTMA) and the viologen derivative N,N′-dimethyl-4,4-bipyridinium dichloride (MV) in a simple and safe aqueous solution as redox-active materials. The resulting battery using these electrolyte solutions has capacities of 54 Ah L−1, giving a total energy density of 38 Wh L−1 at a cell voltage of 1.4 V. With peak current densities of up to 200 mA cm−2 the TEMPTMA/MV system is a suitable candidate for compact high-capacity and high-power applications.

Quality of life and psychological well being in polycystic ovary syndrome

Abstract: BACKGROUND: Polycystic ovary syndrome (PCOS) is associated with poor quality of life (QoL) and high levels of depression. Existing research is confounded by small sample sizes and inconsistent use of control groups. METHODS: Depression and QoL were assessed in women with PCOS and healthy controls (n 5 1359). The polycystic ovary syndrome health-related QoL questionnaire (PCOSQ) was modified to include an acne subscale. RESULTS: Seventy-one percentage of women with PCOS who were taking anti-androgen (AA) medication and 67% not taking AA medication were classified as depressed. Women with PCOS had lower QoL on all seven factors of the modified PCOSQ (emotional disturbance, weight, infertility, acne, menstrual symptoms, menstrual predictability and hirsutism). Weight was the largest contributor to poor QoL for women taking and not taking AA medication. Women taking AA medication, independent of diagnosis, generally had better QoL than women not taking them. CONCLUSIONS: This large study refines our understanding of depression and QoL in PCOS and demonstrates the need to regularly review the psychological health of women with PCOS.
