Intrinsically disordered regions regulate both catalytic and non-catalytic activities of the MutLα mismatch repair complex.

Nucleic Acids Res 2018 Dec 12. Epub 2018 Dec 12.

Department of Molecular Biosciences and Institute for Cellular and Molecular Biology, University of Texas at Austin, Austin, TX 78712, USA.

Intrinsically disordered regions (IDRs) are present in at least 30% of the eukaryotic proteome and are enriched in chromatin-associated proteins. Using a combination of genetics, biochemistry and single-molecule biophysics, we characterize how IDRs regulate the functions of the yeast MutLα (Mlh1-Pms1) mismatch repair (MMR) complex. Shortening or scrambling the IDRs in both subunits ablates MMR in vivo. Read More

Authors:
Stephanie Ward

20 Century Br Hist 2018 Dec 11. Epub 2018 Dec 11.

Cardiff University, UK.

This article explores working-class women's experiences of political activism in the Labour Party in the 1930s. The article focuses upon the relationships formed with leaders, the bonds with fellow women, and the emotional fulfilment politics could bring, rather than considering the policies and campaigns which drew women into the party. It suggests how working-class women performed a political self which was shaped by but distinctive from a domestic self. Read More

Who suffers from the cumulation of atypical employment? A longitudinal analysis based on Dutch data.

Eur J Public Health 2018 Dec 11. Epub 2018 Dec 11.

Labour Law and Social Policy Department, Tilburg Law School, Tilburg University, Tilburg, The Netherlands.

Our study examines the relationship between the cumulation of employment statuses such as temporary contracts, self-employed, work at home or participating in the business activity of the spouse, and the health of Dutch early career workers. We followed four cohorts of Dutch early career workers that entered the labour market in 2002, 2004, 2006 and 2008 for a period of six years. Based on our fixed effects models, we conclude that men but not women who during their first six years of labour market participation experienced more spells of atypical employment also reported worse self-rated health.

Mucosal healing and bacterial composition in response to enteral nutrition versus steroid based induction therapy - a randomized prospective clinical trial in children with Crohn's disease.

J Crohns Colitis 2018 Dec 12. Epub 2018 Dec 12.

Hôpital Necker Enfants Malades Université Sorbonne Paris Cité, Paris, APHP.

Exclusive Enteral Nutrition (EEN) is as efficacious as corticosteroids (CS) to induce remission in Crohn's disease (CD), without their adverse effects. EEN seems to be more efficient than steroids to induce mucosal healing, but the underlying molecular mechanisms are only sparsely understood. We aimed in the present work to study the anti-inflammatory effects of EEN with Modulen IBD® versus CS in active pediatric CD and to assess its modulatory effects on the intestinal microbiota as compared to steroids.

A transient DMSO treatment increases the differentiation potential of human pluripotent stem cells through the Rb family.

PLoS One 2018 12;13(12):e0208110. Epub 2018 Dec 12.

Department of Psychiatry and Behavioral Sciences, Stanford University School of Medicine, Stanford, California, United States of America.

The propensity for differentiation varies substantially across human pluripotent stem cell (hPSC) lines, greatly restricting the use of hPSCs for cell replacement therapy or disease modeling. Here, we investigate the underlying mechanisms and demonstrate that activation of the retinoblastoma (Rb) pathway in a transient manner is important for differentiation. In prior work, we demonstrated that pre-treating hPSCs with dimethylsulfoxide (DMSO) before directed differentiation enhanced differentiation potential across all three germ layers. Read More

A simple survey protocol for assessing terrestrial biodiversity in a broad range of ecosystems.

PLoS One 2018 12;13(12):e0208535. Epub 2018 Dec 12.

Department of Zoology, Institute of Ecology and Earth Sciences, University of Tartu, Vanemuise, Tartu, Estonia.

Finding standard cost-effective methods for monitoring biodiversity is challenging due to trade-offs between survey costs (including expertise), specificity, and range of applicability. These trade-offs cause a lack of comparability among datasets collected by ecologists and conservationists, which is most regrettable in taxonomically demanding work on megadiverse inconspicuous taxon groups. We have developed a site-scale survey method for diverse sessile land organisms, which can be analyzed over multiple scales and linked with ecological insights and management. Read More

Evidence for encounter-conditional, area-restricted search in a preliminary study of Colombian blowgun hunters.

PLoS One 2018 12;13(12):e0207633. Epub 2018 Dec 12.

University of California Davis, Department of Anthropology, Davis, CA, United States of America.

Active search for prey is energetically costly, so understanding how foragers optimize search has been central to foraging theory. Some theoretical work has suggested that foragers of randomly distributed prey should search using Lévy flights, while work on area-restricted and intermittent search strategies has demonstrated that foragers can use the information provided by prey encounters to more effectively adapt search direction and velocity. Previous empirical comparisons of these search modes have tended to rely on distribution-level analyses, due to the difficulty of collecting event-level data on encounters linked to the GPS tracks of foragers.

Live nanoscopic to mesoscopic topography reconstruction with an optical microscope for chemical and biological samples.

PLoS One 2018 12;13(12):e0207881. Epub 2018 Dec 12.

LAI, Aix Marseille Univ, CNRS, INSERM, Marseille, France.

Macroscopic properties of physical and biological processes like friction, wetting, and adhesion or cell migration are controlled by interfacial properties at the nanoscopic scale. In an attempt to bridge simultaneously investigations at different scales, we demonstrate here how optical microscopy in Wet-Surface Ellipsometric Enhanced Contrast (Wet-SEEC) mode offers imaging and measurement of thin films at solid/liquid interfaces in the range 1-500 nm with lateral optical resolution. A live, label-free and noninvasive methodology integrated with microfluidic devices allowed here characterization of polymers and proteins patterns together with corresponding phenotypes of living cells.

Department of Biochemistry, Molecular Biology, Entomology and Plant Pathology, Mississippi State University, Mississippi State, Mississippi, United States of America.

Plant protein kinases form redundant signaling pathways to perceive microbial pathogens and activate immunity. Bacterial pathogens repress cellular immune responses by secreting effectors, some of which bind and inhibit multiple host kinases. To understand how broadly bacterial effectors may bind protein kinases and the function of these kinase interactors, we first tested kinase-effector (K-E) interactions using the Pseudomonas syringae pv.

Hemodynamic effects of the dipeptidyl peptidase-4 inhibitor linagliptin with renin-angiotensin system inhibitors in type 2 diabetic patients with albuminuria.

J Hypertens 2018 Dec 11. Epub 2018 Dec 11.

Boehringer Ingelheim International GmbH, Ingelheim.

Objective: Concomitant treatment with angiotensin-converting enzyme (ACE) inhibitors and dipeptidyl peptidase-4 (DPP-4) inhibitors is increasingly common. Pharmacological studies have suggested a potential adverse drug interaction between ACE inhibitors and DPP-4 inhibitors resulting in unfavorable hemodynamic changes; very few studies have examined such an interaction between angiotensin II receptor blockers (ARBs) and DPP-4 inhibitors. We investigated blood pressure (BP) and heart rate (HR) during treatment with the DPP-4 inhibitor linagliptin in individuals receiving either ACE inhibitors or ARBs in the MARLINA-T2D trial.

Curr Opin Organ Transplant 2018 Dec 11. Epub 2018 Dec 11.

Transplant Nephrology, Keck Hospital of USC, California, USA.

Purpose Of Review: Delayed graft function (DGF) has several long-term graft implications in the field of kidney transplantation and remains a challenge. The incidence of DGF is on the rise because of an increasing use of marginal kidneys in an era of organ shortage. Risk factors for DGF are numerous and stem from multiple sources in the transplant chain starting from the donor to its final allocation in the recipient. Read More

G-protein-coupled formyl peptide receptors play a dual role in neutrophil chemotaxis and bacterial phagocytosis.

Mol Biol Cell 2018 Dec 12:mbcE18060358. Epub 2018 Dec 12.

Chemotaxis Signal Section, Laboratory of Immunogenetics, National Institute of Allergy and Infectious Diseases, National Institutes of Health, Rockville, MD.

A dogma of innate immunity is that neutrophils use G-Protein-coupled receptors (GPCRs) for chemoattractant to chase bacteria through chemotaxis and then use phagocytic receptors coupled with tyrosine kinases to destroy opsonized bacteria via phagocytosis. Our current work showed that G-protein-coupled formyl peptide receptors (FPRs) directly mediate neutrophil phagocytosis. Mouse neutrophils lacking formyl peptide receptors (Fpr1/2) are defective in the phagocytosis of E. Read More

Actomyosin contractility modulates Wnt signaling through adherens junction stability.

Mol Biol Cell 2018 Dec 12:mbcE18060345. Epub 2018 Dec 12.

Department of Molecular Biology and Biochemistry, Centre for Cell Biology, Development and Disease, Simon Fraser University, Burnaby, V5A 1S6, Canada.

Actomyosin contractility can influence the canonical Wnt signaling pathway in processes like mesoderm differentiation and tissue stiffness during tumorigenesis. We identified that increased non-muscle myosin II activation and cellular contraction inhibited Wnt target gene transcription in developing Drosophila imaginal discs. Genetic interactions studies were used to show that this effect was due to myosin-induced accumulation of cortical F-actin resulting in clustering and accumulation of E-cadherin to the adherens junctions.

Single molecule dynamics of the P granule scaffold MEG-3 in the C. elegans zygote.

Mol Biol Cell 2018 Dec 12:mbcE18060402. Epub 2018 Dec 12.

Department of Biological Sciences, Dartmouth College, Hanover NH 03755, USA.

During the asymmetric division of the C. elegans zygote, germ (P) granules are disassembled in the anterior cytoplasm and stabilized/assembled in the posterior cytoplasm, leading to their inheritance by the germline daughter cell. P granule segregation depends on MEG-3 and MEG-4, which are enriched in P granules and in the posterior cytoplasm surrounding P granules. Read More

The transfer function of the rhesus macaque oculomotor system for small-amplitude slow motion trajectories.

J Neurophysiol 2018 Dec 12. Epub 2018 Dec 12.

Werner Reichardt Centre for Integrative Neuroscience, Germany.

Two main types of small eye movements occur during gaze fixation: microsaccades and slow ocular drifts. While microsaccade generation has been relatively well-studied, ocular drift control mechanisms are unknown. Here we explored the degree to which monkey smooth eye movements, on the velocity scale of slow ocular drifts, can be generated systematically. Read More

Gaussian Process Surrogate Models for the CMA Evolution Strategy.

Evol Comput 2018 Dec 12:1-30. Epub 2018 Dec 12.

Institute of Computer Science, Czech Academy of Sciences, Pod Vodárenskou věží 2, 182 07 Prague, Czech Republic

This article deals with Gaussian process surrogate models for the Covariance Matrix Adaptation Evolutionary Strategy (CMA-ES)-several already existing and two by the authors recently proposed models are presented. The work discusses different variants of surrogate model exploitation and focuses on the benefits of employing the Gaussian process uncertainty prediction, especially during the selection of points for the evaluation with a surrogate model. The experimental part of the paper thoroughly compares and evaluates the five presented Gaussian process surrogate and six other state-of-the-art optimizers on the COCO benchmarks. Read More
