Predicted short and long-term impact of deworming and water, hygiene, and sanitation on transmission of soil-transmitted helminths.

PLoS Negl Trop Dis 2018 Dec 6;12(12):e0006758. Epub 2018 Dec 6.

Research School of Population Health, College of Medicine, Biology and Environment, The Australian National University, Canberra, Australian Capital Territory, Australia.

Background: Regular preventive chemotherapy (PCT) targeting high-risk populations is an effective way to control STH in the short term, but sustainable long-term STH control is expected to require improved access to water, sanitation, and hygiene (WASH). However, experimental studies have not been able to conclusively demonstrate the benefit of WASH in preventing STH (re-)infections. We investigated the impact of WASH on STH infections during and after PCT using mathematical modelling. Read More

Longer schooling but not better off? A quasi-experimental study of the effect of compulsory schooling on biomarkers in France.

Soc Sci Med 2018 Nov 23;220:379-386. Epub 2018 Nov 23.

Department of Social and Behavioral Sciences, Harvard T H Chan School of Public Health, 677 Huntington Ave, Boston, MA, 02115, USA; CUNY Graduate School of Public Health and Health Policy, 205 East 42nd Street, New York, NY, 10017, USA.

Less schooling is associated with increased biological risks for chronic disease, but whether increasing years of schooling through policy interventions reduces these risks remains unclear. We examine the effect of a major education reform introduced in 1959 that raised the minimum school leaving age from 14 to 16 years in France, offering a unique natural experiment. We assess the causal impact of increased schooling duration on 16 biomarkers of cardiovascular, metabolic, organ and immune function in a large cohort of men and women born around 1953. Read More

Winning smiles: Signalling reward by overlapping and non-overlapping emotional valence differentially affects performance and neural activity.

Neuropsychologia 2018 Dec 3. Epub 2018 Dec 3.

Department of Experimental Psychology, Ghent University.

It is well-known that both emotional and motivational events greatly impact our behaviour. Based on previous work on the interplay between these two constructs, the present study aimed to test whether and how concurrent emotion and reward signals interact in terms of their basic valence, when both are equally relevant to the task. To this end, we employed a novel fMRI paradigm in which reward availability was explicitly signalled by positive, neutral, or negative facial expressions (using block-wise instructions). Read More

Cracking the Function of Layers in the Sensory Cortex.

Neuron 2018 Dec;100(5):1028-1043

Department of Molecular and Cell Biology, University of California, Berkeley, Berkeley, CA, USA; The Helen Wills Neuroscience Institute, University of California, Berkeley, Berkeley, CA, USA.

Understanding how cortical activity generates sensory perceptions requires a detailed dissection of the function of cortical layers. Despite our relatively extensive knowledge of their anatomy and wiring, we have a limited grasp of what each layer contributes to cortical computation. We need to develop a theory of cortical function that is rooted solidly in each layer's component cell types and fine circuit architecture and produces predictions that can be validated by specific perturbations.

Pharmacological treatment of obesity

Rev Med Inst Mex Seguro Soc 2018 11 30;56(4):395-409. Epub 2018 Nov 30.

Instituto Mexicano del Seguro Social, Hospital de Especialidades “Dr. Bernardo Sepúlveda Gutiérrez”, Unidad de Investigación Médica en Endocrinología Experimental. Ciudad de México, México

More than 70% of the population in Mexico is overweight or obese, affecting mainly people in productive age. Obesity is associated with the development of diseases that increase cardiovascular risk (diabetes mellitus, hypertension or atherogenic dyslipidemia), diseases that limit the quality of life of the patient (osteoarthrosis or sleep apnea) and even with the increase in the incidence of certain types of cancer (breast or colon). It is evident that the decrease of at least 5% of body weight induces improvement in all these factors; however, in some patients it is difficult to achieve this goal only with lifestyle modifications.

Acute effects of zinc and insulin on arcuate anorexigenic Proopiomelanocortin (POMC) neurons.

Br J Pharmacol 2018 Dec 6. Epub 2018 Dec 6.

Division of Hypothalamic Research, the University of Texas Southwestern Medical Center at Dallas, Dallas, Texas, USA.

Background And Purpose: Acute insulin administration results in a hyperpolarization and concomitant decrease of firing rate in a subpopulation of arcuate Proopiomelanocortin (POMC) and Neuropeptide Y/Agouti-related peptide (NPY/AgRP) cells. This rapid effect on cellular activity has been implicated as a cellular correlate of insulin effects on energy balance and glucose homeostasis. Recent evidence suggests that zinc in mammalian insulin formulations is required for the insulin-induced inhibition of arcuate POMC neurons, while guinea-pig insulin, which fails to bind zinc, activates POMC neurons in mice.

Spectral clustering with distinction and consensus learning on multiple views data.

PLoS One 2018 6;13(12):e0208494. Epub 2018 Dec 6.

School of Computer and Information Technology, Shanxi University, Taiyuan, China.

Since multi-view data are available in many real-world clustering problems, multi-view clustering has received considerable attention in recent years. Most existing multi-view clustering methods learn consensus clustering results but do not make full use of the distinct knowledge in each view so that they cannot well guarantee the complementarity across different views. In this paper, we propose a Distinction based Consensus Spectral Clustering (DCSC), which not only learns a consensus result of clustering, but also explicitly captures the distinct variance of each view.

Alpha7 acetylcholine receptor autoantibodies are rare in sera of patients diagnosed with schizophrenia or bipolar disorder.

PLoS One 2018 6;13(12):e0208412. Epub 2018 Dec 6.

Department of Psychiatry and Neuropsychology, School for Mental Health and Neuroscience, Maastricht University, Maastricht, the Netherlands.

The α7 acetylcholine receptor (AChR) has been linked with the onset of psychotic symptoms and we hypothesized therefore that it might also be an autoimmune target. Here, we describe a new radioimmunoassay (RIA) using iodine 125-labelled α-bungarotoxin and membrane extract from transfected HEK293 cells expressing human α7 AChR. This RIA was used to analyze sera pertaining to a cohort of 711 subjects, comprising 368 patients diagnosed with schizophrenia spectrum disorders, 140 with bipolar disorder, 58 individuals diagnosed of other mental disorders, and 118 healthy comparison subjects.

Human bone marrow contains high levels of extracellular vesicles with a tissue-specific subtype distribution.

PLoS One 2018 6;13(12):e0207950. Epub 2018 Dec 6.

Gynecological Endocrinology and Reproductive Medicine, Medical University Innsbruck, Innsbruck, Austria.

Introduction: Extracellular vesicles (EV) are shed from a broad variety of cells and play an important role in activation of coagulation, cell to cell interaction and transport of membrane components. They are usually measured as circulating EV in peripheral blood (PB) and other body fluids. However, little is known about the distribution, presence and impact of EV and their subpopulations in bone marrow (BM). Read More

Effects of turbulent aggregation on clay floc breakup and implications for the oceanic environment.

PLoS One 2018 6;13(12):e0207809. Epub 2018 Dec 6.

Remote Sensing Division, U.S. Naval Research Laboratory, Washington D.C., United States of America.

Understanding how turbulence impacts marine floc formation and breakup is key to predicting particulate carbon transport in the ocean. While floc formation and sinking rate has been studied in the laboratory and in-situ, the breakup response to turbulence has attracted less attention. To address this problem, the breakup response of bentonite clay particles flocculated in salt water was studied experimentally. Read More

Aberrations in the female reproductive organs and a role of telocytes in a rat model of anorexia nervosa.

Folia Med Cracov 2018 ;58(3):115-125

Department of Pathophysiology, Jagiellonian University Medical College, Czysta 18, Kraków, Poland.

Background: Anorexia nervosa is a widely prevalent eating disorder that o en leads to life-threatening complications. Since it mostly concerns females, many authors have focused on studying the reproductive system in anorexic women. Recently discovered telocytes may give a new insight into the pathophysiology of gynecological complications in these patients. Read More

Quasi-degenerate magnetic states in α-RuCl.

J Phys Condens Matter 2019 Jan;31(2):025803

Department of Physics and Beijing Key Laboratory of Opto-electronic Functional Materials & Micro-nano Devices, Renmin University of China, Beijing 100872, People's Republic of China.

Exploring quantum spin liquid (QSL) state has both fundamental scientific value and realistic application potential. Recently, α-RuCl was experimentally observed to hold in-plane zigzag antiferromagnetic (AFM) order at low temperature, which was further proposed to be proximate to a Kitaev QSL ground state. We have studied the magnetic properties of α-RuCl in the framework of electronic structure calculation based on density functional theory (DFT) with Hubbard U correction (DFT+U) and spin-orbit coupling.

3D surface condensation of large atomic shear strain in nanoscale metallic glasses under low uniaxial stress.

J Phys Condens Matter 2019 Jan;31(2):025401

Materials Science Program, School of Mechanical, Industrial and Manufacturing Engineering, Oregon State University, Corvallis, OR 97331, United States of America.

Nanoscale metallic glasses (MGs) are frequently used in experimental and computational studies to probe the deformation mechanisms in amorphous metals. Potential consequences of the significant surface to volume ratio in these extremely small materials, nevertheless, are not well understood. Here, using molecular dynamics simulations and novel selective 3D visualization, we show that significant irreversible atomic shear strain condenses on the 3D surface of these materials under low uniaxial stress, while the interior atoms are bearing much lower, mostly reversible shear strain.

On the role of magnesium in a LiF:Mg,Ti thermoluminescent dosimeter.

J Phys Condens Matter 2019 Jan;31(2):025502

Instituto de Física, Universidad Nacional Autónoma de México, 04510 Coyoacan Mexico City, Mexico.

LiF doped with Mg and Ti is the most widely used thermoluminescent (TL) dosimeter for a large variety of applications. It has been argued that the Mg dopant is the most important defect in the TL process. Besides the common F-centre defects in LiF, optical absorption measurements have suggested the presence of Mg-related absorption bands at 380 nm (3. Read More

Selectivity map for molecular beam epitaxy of advanced III-V quantum nanowire networks.

Nano Lett 2018 Dec 6. Epub 2018 Dec 6.

Selective area growth is a promising technique to enable fabrication of scalable III-V nanowire networks required to test proposals for Majorana-based quantum computing devices. However, the contours of the growth parameter window resulting in selective growth remain undefined. Herein, we present a set of experimental techniques which unambiguously establish the parameter space window resulting in selective III-V nanowire networks growth by molecular beam epitaxy.
