Exploration of Shared Genetic Architecture Between Subcortical Brain Volumes and Anorexia Nervosa.

Mol Neurobiol 2018 Dec 5. Epub 2018 Dec 5.

Division of Psychological and Social Medicine and Developmental Neurosciences, Faculty of Medicine, Technische Universität Dresden, Fetscherstr. 74, 01307, Dresden, Germany.

In MRI scans of patients with anorexia nervosa (AN), reductions in brain volume are often apparent. However, it is unknown whether such brain abnormalities are influenced by genetic determinants that partially overlap with those underlying AN. Here, we used a battery of methods (LD score regression, genetic risk scores, sign test, SNP effect concordance analysis, and Mendelian randomization) to investigate the genetic covariation between subcortical brain volumes and risk for AN based on summary measures retrieved from genome-wide association studies of regional brain volumes (ENIGMA consortium, n = 13,170) and genetic risk for AN (PGC-ED consortium, n = 14,477).

BMC Cancer 2018 Nov 22;18(1):1158. Epub 2018 Nov 22.

Charité-Universitätsmedizin Berlin corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Institute of Pathology, Charitéplatz 1, 10117, Berlin, Germany.

Background: Rearrangements of the anaplastic lymphoma kinase (ALK) belong to the promising targets in the therapy of advanced non-small cell lung cancer (NSCLC) and are predominantly detected by immunohistochemistry (IHC) and/or fluorescence in-situ hybridization (FISH). However, both methods occasionally produce discordant results, especially in so-called borderline (BL) cases, showing ALK FISH-positive signals in 10-20% of the tumor nuclei around the cutoff (15%). This leads to a diagnostic and thus to a therapeutic dilemma. Read More

Intercepting the Disilene-Silylsilylene Equilibrium.

Angew Chem Int Ed Engl 2018 Nov 21. Epub 2018 Nov 21.

University of Edinburgh, School of Chemistry, Joseph Black Building, West Mains Road, EH9 3FJ, Edinburgh, UNITED KINGDOM.

The equilibrium between disilenes (R2Si=SiR2) and their silylsilylene (R3Si-SiR) isomers has previously been inferred but not directly observed, except in the case of the parent system H2Si=SiH2. Here, we report a new method to prepare base-coordinated disilenes with hydride substituents. By varying the bulk of the coordinating base and other silicon substituents, we have been able to control the rearrangement of disilene adducts to their silylsilylene tautomers. Read More

Reactive Dimerization of an N-heterocyclic Plumbylene: CH Activation with PbII.

Angew Chem Int Ed Engl 2018 Nov 20. Epub 2018 Nov 20.

GERMANY.

The N-heterocyclic plumbylene [Fe{(η5-C5H4)NSiMe3}2Pb:] is in equilibrium with an unprecedented dimer in solution, whose formation involves the cleavage of a strong C-H bond and concomitant formation of a Pb-C and an N-H bond. According to a mechanistic DFT assessment, dimer formation does not involve direct PbII insertion into a cyclopentadienyl C-H bond, but is best described as an electrophilic substitution. The bulkier plumbylene [Fe{(η5-C5H4)NSitBuMe2}2Pb:], in turn, shows no dimerization, but compensates its electrophilicity by formation of an intramolecular Fe-Pb bond. Read More

Substrate fluxes in brown adipocytes upon adrenergic stimulation and uncoupling protein 1 ablation.

Life Sci Alliance 2018 Dec 14;1(6):e201800136. Epub 2018 Nov 14.

Chair of Molecular Nutritional Medicine, TUM School of Life Sciences, Technical University of Munich, Freising, Germany.

Brown adipocytes are highly specialized cells with the unique metabolic ability to dissipate chemical energy in the form of heat. We determined and inferred the flux of a number of key catabolic metabolites, their changes in response to adrenergic stimulation, and the dependency on the presence of the thermogenic uncoupling protein 1 and/or oxidative phosphorylation. This study provides reference values to approximate flux rates from a limited set of measured parameters in the future and thereby allows to evaluate the plausibility of claims about the capacity of metabolic adaptations or manipulations.

Global knowledge gaps in the prevention and control of bovine viral diarrhoea (BVD) virus.

Transbound Emerg Dis 2018 Nov 11. Epub 2018 Nov 11.

EpiCentre, School of Veterinary Science, Massey University, Palmerston North, New Zealand.

The significant economic impacts of bovine viral diarrhoea (BVD) virus have prompted many countries worldwide to embark on regional or national BVD eradication programmes. Unlike other infectious diseases, BVD control is highly feasible in cattle production systems because the pathogenesis is well understood and there are effective tools to break the disease transmission cycle at the farm and industry levels. Coordinated control approaches typically involve directly testing populations for virus or serological screening of cattle herds to identify those with recent exposure to BVD, testing individual animals within affected herds to identify and eliminate persistently infected (PI) cattle, and implementing biosecurity measures such as double-fencing shared farm boundaries, vaccinating susceptible breeding cattle, improving visitor and equipment hygiene practices, and maintaining closed herds to prevent further disease transmission.

Intermolecular structural correlations in model globular and unconcatenated ring polymer liquids.

Soft Matter 2018 Nov;14(45):9132-9142

Department of Polymer Science and Engineering, University of Massachusetts, Amherst, MA 01003, USA.

We employ the field theoretic polymer integral equation theory to construct a segment-level theory for the thermodynamics and pair structure of dense liquids of interpenetrating ring polymers and a simple globule model. The latter is defined by a fractal mass distribution on all internal length scales with an exponent equal to the spatial dimension (dF = ds = 3). In an isochoric ensemble the dimensionless compressibility and pressure is predicted to vary exponentially with macromolecular volume fraction. Read More

Psychophysiological reactivity, coping behaviour and intrusive memories upon multisensory Virtual Reality and Script-Driven Imagery analogue trauma: A randomised controlled crossover study.

J Anxiety Disord 2018 Oct 18;59:42-52. Epub 2018 Aug 18.

Department of Psychology, Clinical Psychology and Psychotherapy, University of Freiburg, 79085 Freiburg, Germany.

Background: Peri- and post-traumatic factors predict the differential development of stress-associated mental disorders. Prospective designs assessing these risk factors in real-time under controlled experimental conditions can overcome limitations of retrospective designs. Therefore, we aimed to investigate multi-sensory, experimental analogues of a traumatic experience delivered in Virtual Reality (VR) or Script-Driven Imagery (SDI). Read More

Development and validation of a triplex quantitative real-time PCR assay to detect efflux pump-mediated antibiotic resistance in Burkholderia pseudomallei.

Future Microbiol 2018 09 26;13:1403-1418. Epub 2018 Sep 26.

Global & Tropical Health Division, Menzies School of Health Research, Darwin, Northern Territory, Australia.

Aim: To develop a probe-based triplex quantitative real-time PCR assay to simultaneously detect the upregulation of the efflux pumps AmrAB-OprA, BpeAB-OprB and BpeEF-OprC in Burkholderia pseudomallei strains exhibiting increased minimum inhibitory concentrations toward meropenem, doxycycline or trimethoprim-sulfamethoxazole.

Methods: The triplex assay was developed and subsequently tested on RNA isolated from eight clinical and eight laboratory-generated B. pseudomallei mutants harboring efflux pump regulator mutations. Read More

Fiber-bundle model with time-dependent healing mechanisms to simulate progressive failure of snow.

Phys Rev E 2018 Aug;98(2-1):023002

WSL Institute for Snow and Avalanche Research SLF, Flüelastrasse 11, 7260 Davos Dorf, Switzerland.

Snow is a heterogeneous material with strain- and/or load-rate-dependent strength. In particular, a transition from ductile-to-brittle failure behavior with increasing load rate is observed. The rate-dependent behavior can partly be explained with the existence of a unique healing mechanism in snow that stems from its high homologous temperature (temperature close to melting point).

Comparative Analysis of Mechanical Properties and Metal-Ceramic Bond Strength of Co-Cr Dental Alloy Fabricated by Different Manufacturing Processes.

Materials (Basel) 2018 Sep 22;11(10). Epub 2018 Sep 22.

Section Medical Materials Science and Technology, University Hospital Tübingen, Osianderstr. 2-8, Tübingen 72076, Germany.

Cobalt-chromium (Co-Cr) alloy is a widely used base material for dental fixed prostheses. These restorations can be produced through casting technique, subtractive or additive manufacturing technologies. However, limited information is available regarding the influence of manufacturing techniques on the properties of Co-Cr alloy since most studies used different chemical compositions of Co-Cr alloy for different manufacturing methods.

Novel approach to discriminate left bundle branch block from nonspecific intraventricular conduction delay using pacing-induced functional left bundle branch block.

J Interv Card Electrophysiol 2018 Dec 19;53(3):347-355. Epub 2018 Sep 19.

Department of Cardiology, Angiology, and Pneumology, University Hospital Heidelberg, Im Neuenheimer Feld 410, 69120, Heidelberg, Germany.

Purpose: Left bundle branch block (LBBB) has a predictive value for response to cardiac resynchronization therapy as reported by Zareba et al. (Circulation 123(10):1061-1072, 2011). However, based on ECG criteria, the discrimination between complete LBBB and nonspecific intraventricular conduction delay is challenging. Read More

Seroepidemiology of , Etiologic Agent of Melioidosis, in the Ouest and Sud-Est Departments of Haiti.

Am J Trop Med Hyg 2018 Nov;99(5):1222-1228

Emerging Pathogens Institute, University of Florida, Gainesville, Florida.

, the etiological agent of melioidosis, has been hypothesized to be endemic throughout the Caribbean, including the impoverished nation of Haiti. However, because of the protean clinical manifestations, presence of asymptomatic infections, and limited medical diagnostic capacity, the identification of active melioidosis cases remains challenging. A seroepidemiological study was conducted using a novel enzyme-linked immunosorbent assay (ELISA) to detect antibodies toward in the native population. Read More

The gut microbiota promotes hepatic fatty acid desaturation and elongation in mice.

Nat Commun 2018 09 14;9(1):3760. Epub 2018 Sep 14.

Ernährungsphysiologie, Technische Universität München (TUM), Freising, 85354, Germany.

Interactions between the gut microbial ecosystem and host lipid homeostasis are highly relevant to host physiology and metabolic diseases. We present a comprehensive multi-omics view of the effect of intestinal microbial colonization on hepatic lipid metabolism, integrating transcriptomic, proteomic, phosphoproteomic, and lipidomic analyses of liver and plasma samples from germfree and specific pathogen-free mice. Microbes induce monounsaturated fatty acid generation by stearoyl-CoA desaturase 1 and polyunsaturated fatty acid elongation by fatty acid elongase 5, leading to significant alterations in glycerophospholipid acyl-chain profiles.

MILK COMPOSITION OF INDIAN RHINOCEROS ( RHINOCEROS UNICORNIS) AND CHANGES OVER LACTATION.

J Zoo Wildl Med 2018 Sep;49(3):704-714

The objective of this study was to determine the major nutrient composition of Indian rhinoceros milk ( Rhinoceros unicornis) over the first 13 mo of an 18-mo lactation period and to compare the results to those of previous studies on rhinoceros, African elephant ( Loxodonta africana), and horse milk ( Equus ferus caballus). The following parameters were measured: dry matter (DM), crude ash (ASH), crude protein (CP), ether extract (EE), nitrogen-free extract (NFE; calculated), lactose, calcium (Ca), phosphorus (P), magnesium (Mg), fatty acids (FAs), and gross energy (GE). DM, ASH, CP, and EE were determined with a proximate analysis, lactose with infrared spectroscopy and an enzymatic method, minerals with an autoanalyzer, FA with gas chromatography, and GE with bomb calorimetry.
