Endometriosis is a leading cause of infertility in women of reproductive age. It involves the occurrence of endometrial tissue outside the uterine endometrium, mainly in the peritoneal cavity. Prostaglandin E 2 is up regulated in the peritoneal cavity in endometriosis and is produced by macrophages and ectopic endometrial cells. This prostaglandin is involved in the pathophysiology of the disease and elicits cell signals via four receptor types. Prostaglandin E 2 increases estrogen synthesis bydoi:10.3109/09513590.2011.588753 pmid:22003899 fatcat:hbz5cxyk5rgsrbw6b365lylopy

Prostaglandin E 2 affects leukocyte populations and promotes angiogenesis through its effect on estrogen and up regulation of vascular endothelial growth factor (VEGF). Dienogest is a synthetic progestin targeting expression of genes involved in prostaglandin synthesis.

Abstract: Ian Bremmer published a treatise on the stability of states built on the notion that states fall along a curve resembling a slanted "J" when plotting their stability against openness. States in the turnover process are considered unstable, and are at risk of either reversing to a closed and stable system or even collapsing. Our paper shifts the J curve's associated conditions to a model to more accurately specify the causes of reversal in which crises of instability and backsliding occur. We define stability as a function of two state dimensions: authority and capacity, and apply the remaining state dimension of legitimacy as a proxy for openness. We find that transitions can reverse, oscillate, or simply stall, which are exemplified in the different types of states we categorize. The paper concludes with implications for policy and the application of the model to conflict prediction.

BACKGROUND: The effect of the menopause and HRT on the intervertebral discs has not been investigated. METHODS: One hundred women were recruited, comprising of 44 post-menopausal women on HRT, 33 untreated post-menopausal women and 23 pre-menopausal women. The height of the intervertebral discs between the 12th thoracic vertebra and the 3rd lumbar vertebra was measured by utilizing the bone densitometer height cursors. RESULTS: The untreated menopausal group of women had the lowest total discdoi:10.1093/humrep/dei251 pmid:16113041 fatcat:yaxllc267zcijah2myp2gfeeo4

The 2nd intervertebral disc consistently maintained a significant difference between the untreated menopausal group (D2: 0.63 ± 0.13) and the other two groups (pre-menopausal group (D2: 0.72 ± 0.09 cm) and treated menopausal group (D2: 0.73 ± 0.12 cm) (P > 0.02). CONCLUSIONS: Estrogen-replete women appear to maintain higher intervertebral discs compared to untreated post-menopausal women. The estrogenic milieu may be relevant because of the significant impact it has on the hydrophilic glycosaminoglycans, the water content, collagen and elastin of the intervertebral discs. The maintenance of adequate disc height may allow the intervertebral discs to retain their discoid shape and viscoelastic function, containing vertical forces which may threaten spinal architecture leading to vertebral body compression fractures.

Transport of Na + and Li + under the influence of an electric field in twinned quartz is simulated using molecular dynamics techniques. Comparison between bulk transport and transport along twin boundaries shows that the cations are trapped inside twin walls for weak fields along the crystallographic c-axis. Stronger fields lead to transport along twin walls with significantly lower mobility than in the bulk. With E along , transport in the wall is faster than in the bulk.

The eMinerals Virtual Organisation consists of a consortium of individuals affiliated to geographically distributed academic institutions. Collaborative tools are essential in order to facilitate cooperative work within this Virtual Organisation. The Access Grid Toolkit has been widely adopted for this purpose, delivering high quality group-to-group video and audio conferencing.

Diabetes mellitus (DM) is well established as a short-term prognostic indicator after myocardial infarction (MI), but little long-term data are available. Hypothesis: The objective of the study was to assess the impact of DM and other patient characteristics at baseline on long-term mortality after acute MI. Methods: Patients who were hospitalized with MI from December 1990 to November 1992 were recruited. Baseline data were recorded and patients were followed up through January 31, 2008, todoi:10.1002/clc.20776 pmid:20641120 fatcat:fq2nkdipf5h25aufb2wr43az74

Results: The study followed 337 patients (mean age 66.4 y, 61.1% men) for a median of 16.6 years. Using Cox regression analysis, survival was associated with history of MI (hazard ratio [HR]: 1.47, P = 0.016), DM at baseline (HR: 1.31, P = 0.038), and age (HR: 1.061 for each additional year, P < 0.001). By multivariable regression, cardiovascular mortality was also associated with previous MI (HR: 1.58, P = 0.017), DM at baseline (HR: 1.69, P = 0.001), and age (HR: 1.075 for each additional year, P < 0.001). There was no statistically significant difference between the HRs for history of MI and history of DM. Conclusions: Diabetic patients with MI have a higher long-term all-cause and cardiovascular mortality. Our data also show that in patients with MI, DM confers the same level of risk as a previous MI. This extends to patients with documented MI, our concept of diabetes being a coronary heart disease equivalent. Based on this and on data from the literature, we propose that it would be more accurate to consider DM as an MI equivalent rather than a coronary heart disease equivalent. The authors have no funding, financial relationships, or conflicts of interest to disclose. mortality during long-term follow-up (median 16.6 y; range, 15.3-17.2 y) of a cohort of patients who had had an MI.
We have studied the atomic structure of 90 • rotation twin walls in orthorhombic CaTiO 3 (symmetry Pbnm) at low temperature (10 K) and their effects on oxygen vacancies. The wall thickness was found to be 2.3 nm at T T c and it was found that it is energetically favourable for such vacancies to reside in the wall, particularly when bridging titania ions in the (001) plane. The binding energy of an oxygen vacancy in the wall with respect to the bulk is calculated to be 1.2 eV. 1 www.esc.cam.ac.uk/minscidoi:10.1088/0953-8984/15/14/305 fatcat:ew6raeznpbfahkvm6ctv4m4lyy
Rare ovarian cancers (ROCs) are OCs with an annual incidence of fewer than 6 cases per 100,000 women. They affect women of all ages, but due to their low incidence and the potential clinical inexperience in management, there can be a delay in diagnosis, leading to a poor prognosis. The underlying causes for these tumors are varied, but generally, the tumors arise due to alterations in gene/protein expression in cellular processes that regulate normal proliferation and its checkpoints.doi:10.3390/cancers13205040 pmid:34680193 fatcat:nn6t4l6rljdp7gcnqyp4cx6yv4

Long non-coding RNA (lncRNA) are defined as transcribed RNA molecules, more than 200 nucleotides in length which are not translated into proteins. They regulate gene expression through several mechanisms and therefore add another level of complexity to the regulatory mechanisms affecting tumor development. Since few studies have been performed on ROCs, in this review we summarize the mechanisms of action of lncRNA in OC, with an emphasis on ROCs.
Reliable identification of copy number aberrations (CNA) from comparative genomic hybridization data would be improved by the availability of a generalised method for processing large datasets. To this end, we developed swatCGH, a data analysis framework and region detection heuristic for computational grids. swatCGH analyses sequentially displaced (sliding) windows of neighbouring probes and applies adaptive thresholds of varying stringency to identify the 10% of each chromosome that containsdoi:10.1155/2012/876976 pmid:23008709 pmcid:PMC3449101 fatcat:drqvimfhifeopg3ttopah2ml74

We used the method to analyse a published dataset, comparing data preprocessed using four different DNA segmentation algorithms, and two methods for prioritising the detected CNAs. The consolidated list of the most commonly detected aberrations confirmed the value of swatCGH as a simplified high-throughput method for identifying biologically significant CNA regions of interest.
