Evidence based survey of the distribution volume of ethanol: Comparison of empirically determined values with anthropometric measures.

Forensic Sci Int 2018 Nov 13;294:124-131. Epub 2018 Nov 13.

Principal Forensic Services, Bromley, Kent, UK.

The Widmark equation is commonly used when blood alcohol calculations are required in forensic and legal medicine, such as in road-traffic cases and alcohol-related deaths. An important biological variable in this connection is the volume of distribution (V) of ethanol, which is commonly referred to as the rho-factor. Although a person's V can be determined empirically through controlled drinking experiments, this approach is not very practical in reality. Read More

Molecular Imaging of mGluR5 Availability with [C]ABP68 in Glutaminase Heterozygous Mice.

Cell Mol Neurobiol 2018 Dec 14. Epub 2018 Dec 14.

Molecular Imaging Center Antwerp, University of Antwerp, Antwerp, Belgium.

Many PET tracers enable determination of fluctuations in neurotransmitter release, yet glutamate specifically can not be visualized in a noninvasive manner. Several studies point to the possibility of visualizing fluctuations in glutamate release by changes in affinity of the mGluR5 radioligand [C]ABP688. These studies use pharmacological challenges to alter glutamate levels, and so probe release, but have not measured chronic alterations in receptor occupancy due to altered neurotransmission relevant to chronic neuropsychiatric disorders or their treatment.

Predicting 7-year mortality for use with evidence-based guidelines for Prostate-Specific Antigen (PSA) testing: findings from a large prospective study of 123 697 Australian men.

BMJ Open 2018 Dec 14;8(12):e022613. Epub 2018 Dec 14.

Department of Medical Epidemiology and Biostatistics, Karolinska Institutet, Stockholm, Sweden.

Objectives: To develop and validate a prediction model for short-term mortality in Australian men aged ≥45years, using age and self-reported health variables, for use when implementing the Australian Clinical Practice Guidelines for Prostate-Specific Antigen (PSA) Testing and Early Management of Test-Detected Prostate Cancer. Implementation of one of the Guideline recommendations requires an estimate of 7-year mortality.

Design: Prospective cohort study using questionnaire data linked to mortality data. Read More

Clinical and genetic associations of renal function and diabetic kidney disease in the United Arab Emirates: a cross-sectional study.

BMJ Open 2018 Dec 14;8(12):e020759. Epub 2018 Dec 14.

Center of Biotechnology, Khalifa University, Abu Dhabi, United Arab Emirates.

Objectives: Within the Emirati population, risk factors and genetic predisposition to diabetic kidney disease (DKD) have not yet been investigated. The aim of this research was to determine potential clinical, laboratory and reported genetic loci as risk factors for DKD.

Research Design And Methods: Four hundred and ninety unrelated Emirati nationals with type 2 diabetes mellitus (T2DM) were recruited with and without DKD, and clinical and laboratory data were obtained. Read More

Towards quantitative microbiome community profiling using internal standards.

Appl Environ Microbiol 2018 Dec 14. Epub 2018 Dec 14.

Division of Earth and Ocean Sciences, Nicholas School of the Environment, Duke University, Durham, NC 27708, USA

An inherent issue of high-throughput rRNA gene tag sequencing microbiome surveys is that they provide compositional data in relative abundances. This often leads to spurious correlations making the interpretation of relationships to biogeochemical rates challenging. To overcome this issue, we quantitatively estimated the abundance of microorganisms by spiking in known amounts of internal DNA standards. Read More

Population genetics and characterization of isolates in western jackdaws and game birds in Finland.

Appl Environ Microbiol 2018 Dec 14. Epub 2018 Dec 14.

Department of Food Hygiene and Environmental Health, Faculty of Veterinary Medicine, University of Helsinki, Helsinki, FI-00014, Finland

Poultry is considered a major reservoir and source of human campylobacteriosis but the roles of environmental reservoirs, including wild birds, have not been assessed in depth. In this study, we isolated and characterized from western jackdaws (n=91, 43%), mallard ducks (n=82, 76%) and pheasants (n=9, 9%). Most of the western jackdaw and mallard duck isolates represented MLST sequence types (STs) that diverged from those previously isolated from human patients and various animal species, whereas all pheasant isolates represented ST-19, a common ST among human patients and other hosts worldwide.

Pipeline shield with single antiplatelet therapy in aneurysmal subarachnoid haemorrhage: multicentre experience.

J Neurointerv Surg 2018 Dec 14. Epub 2018 Dec 14.

Institute of Neurological Sciences, Prince of Wales Hospital, Randwick, New South Wales, Australia.

Background: The Pipeline Embolisation Device with Shield technology (PED-Shield) is suggested to have reduced thrombogenicity. This reduced thrombogenicity may make it possible to use safely in the acute treatment of aneurysmal subarachnoid haemorrhage (aSAH) on single antiplatelet therapy (SAPT).

Objective: To evaluate the safety and efficacy of the off-label use of PED-Shield with SAPT for the acute treatment of aSAH. Read More

Hif-1α-Induced Expression of Il-1β Protects against Mycobacterial Infection in Zebrafish.

J Immunol 2018 Dec 14. Epub 2018 Dec 14.

The Bateson Centre, University of Sheffield, Western Bank, Sheffield S10 2TN, United Kingdom;

Drug-resistant mycobacteria are a rising problem worldwide. There is an urgent need to understand the immune response to tuberculosis to identify host targets that, if targeted therapeutically, could be used to tackle these currently untreatable infections. In this study we use an Il-1β fluorescent transgenic line to show that there is an early innate immune proinflammatory response to well-established zebrafish models of inflammation and infection.

Genetic Nicotinamide N-Methyltransferase () Deficiency in Male Mice Improves Insulin Sensitivity in Diet-Induced Obesity but Does Not Affect Glucose Tolerance.

Diabetes 2018 Dec 14. Epub 2018 Dec 14.

Sanofi Research and Development, Industriepark Hoechst, H823, D-64926 Frankfurt am Main, Germany.

Antisense oligonucleotide knockdown (ASO-KD) of nicotinamide N-methyltransferase (NNMT) in high-fat diet (HFD)-fed mice has been reported to reduce weight gain, plasma insulin and improve glucose tolerance. Using NNMT-ASO-KD or NNMT knockout mice (NNMT), we tested the hypothesis that deletion protects against diet-induced obesity and its metabolic consequences in males and females on obesity-inducing diets. We also examined samples from a human weight reduction (WR) study for adipose (a) expression and plasma 1-methylnicotinamide (MNAM) levels. Read More
