A new study shows that a plant gives less carbon to its root-associated mycorrhizal fungus when targeted by herbivores, but the fungus doesn't retaliate.Objective(s) To assess the association between the ultrasonographic presence of adenomyosis and recurrent miscarriage (RM). Study design A prospective matched case-control study was conducted between March 2018 and December 2018 at Ankara University Hospital. A total of 132 women were assessed with transvaginal ultrasonography for the presence of adenomyosis markers. The case group consisted of 66 women with RM. The control group consisted of 66 women without RM or any other gynaecologic conditions. The rates of ultrasonographic adenomyosis, using strict criteria, were compared between the groups. Other etiologic factors for RM were described in the case group. The primary outcome was the ultrasonographic diagnosis of adenomyosis. Results The ultrasonographic diagnosis of adenomyosis, using diagnostic criteria of at least two markers, was significantly higher in the RM group when compared to the control group (19.7% vs. 6.1%, respectively; P = 0.035). The most common ultrasonographic finding in the RM group was heterogeneous myometrium (18.2%). In the RM group, there was at least one possible risk factor (including adenomyosis) for RM in 42 women (63.6%). The prevalence of adenomyosis in nine women with unexplained RM was 13.6%. selleck chemicals llc Conclusion(s) The prevalence of adenomyosis was significantly increased in women with RM compared to healthy controls. Adenomyosis and uterine anomalies were the most common risk factors associated with RM.Cancer cells exhibit molecular characteristics that confer them different proliferative capacities and survival advantages to adapt to stress conditions, such as deregulation of cellular bioenergetics, genomic instability, ability to promote angiogenesis, invasion, cell dormancy, immune evasion, and cell death resistance. In addition to these hallmarks of cancer, the current cytostatic drugs target the proliferation of malignant cells, being ineffective in metastatic disease. These aspects highlight the need to identify promising therapeutic targets for new generations of anti-cancer drugs. Toxins isolated from snake venoms are a natural source of useful molecular scaffolds to obtain agents with a selective effect on cancer cells. In this article, we discuss the recent advances in the molecular mechanisms of nine classes of snake toxins that suppress the hallmarks of cancer by induction of oxidative phosphorylation dysfunction, reactive oxygen species-dependent DNA damage, blockage of extracellular matrix-integrin signaling, disruption of cytoskeleton network and inhibition of growth factor-dependent signaling. The possible therapeutic implications of toxin-based anti-cancer drug development are also highlighted.The lung function laboratory frequently provides relevant information to the practice of Pulmonology. Clinical interpretation of pulmonary function and exercise tests, however, has more recently been complicated by temporal changes in demographics (higher life expectancy) and anthropometric attributes (increased obesity prevalence) and the surge of polypharmacy in a sedentary population suffering from multiple chronic-degenerative diseases. In this narrative review, we concisely discuss some key challenges to testing interpretation which have been impacted from these epidemiological shifts a) the confounding effects of advanced age and severe obesity, b) the contemporary controversies in the diagnosis of obstruction (including asthma and/or chronic obstructive pulmonary disease), c) the importance of considering the lung diffusing capacity for carbon monoxide (DLCO)/"accessible" alveolar volume (diffusing coefficient, KCO) in association with DLCO to uncover the cause(s) of impaired gas exchange, and d) the modern role of the pulmonary function laboratory (including cardiopulmonary exercise testing) in the investigation of undetermined dyspnea. Following a Bayesian perspective, we suggest interpretative algorithms which consider the pre-test probability of abnormalities as indicated by additional clinical information. We, therefore, adopt a pragmatic approach to help the practicing pulmonologist to apply the information provided by the lung function laboratory to the management of individual patients.Cadherin-based cell-cell junctions help metazoans form polarized sheets of cells, which are necessary for the development of organs and the compartmentalization of functions. The components of the protein complexes that generate cadherin-based junctions have ancient origins, with conserved elements shared between animals as diverse as sponges and vertebrates. In invertebrates, the formation and function of epithelial sheets depends on classical cadherin-containing adherens junctions, which link actin to the plasma membrane through α-, β- and p120 catenins. Vertebrates also have a new type of cadherin-based intercellular junction called the desmosome, which allowed for the creation of more complex and effective tissue barriers against environmental stress. While desmosomes have a molecular blueprint that is similar to that of adherens junctions, desmosomal cadherins - called desmogleins and desmocollins - link intermediate filaments (IFs) rather than actin to the plasma membrane through protein complexes comprising relatives of β-catenin (plakoglobin) and p120 catenin (plakophilins). In turn, desmosomal catenins interact with members of the IF-binding plakin family to create the desmosome-IF linking complex. In this Minireview, we discuss when and how desmosomal components evolved, and how their ability to anchor the highly elastic and tough IF cytoskeleton endowed vertebrates with robust tissues capable of not only resisting but also properly responding to environmental stress.Study objective To determine whether dienogest therapy following endometriosis surgery reduces the risk of endometriosis recurrence compared to expectant management. Data sources Ovid MEDLINE, Ovid EMBASE, PubMed, Cochrane Central Register of Controlled Trials, Web of Science, LILACS, clinicaltrials.gov and International Standard Randomized Controlled Trial Number Registry were searched from inception to March 2019 for observational and randomized controlled trials. Methods of study selection The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were followed. MeSH terms and keywords such as "dienogest", "endometriosis" and "recurrence" were used to identify relevant studies. Tabulation, integration, and results The search yielded 328 studies, 10 of which were eligible for inclusion, representing 1,184 patients treated with dienogest and 846 expectantly managed controls. Among these studies, 9 looked exclusively at endometrioma recurrence, whereas one used reappearance of symptoms as evidence of disease recurrence.
