#1
Sandra Schläfle, Thomas Senn, Peter Gschwind, Reinhard Kohlus
Stripping of mashes with air as stripping gas and low ethanol contents between 3 and 5wt% was investigated in terms of its suitability for continuous bioethanol production. Experiments in a Blenke cascade system were carried out and the results were compared with values obtained from theoretical vapour-liquid-equilibrium calculations. The whole stripping process was energetically evaluated by a simulation in ChemCAD and compared to conventional distillation. Therefore several parameters such as temperature, air volume flow and initial ethanol load of the mash were varied...

BACKGROUND: Non-vitamin K dependent oral anticoagulants (NOACs) significantly decrease overall major bleeding rates compared with vitamin K antagonists (VKAs) but there is conflicting evidence regarding the relative risk of gastrointestinal bleeding. Since data regarding the types, the management, and the outcome of NOAC-associated gastrointestinal bleeding are scarce, we aimed to fill this gap by comparing cases of gastrointestinal bleeding associated with NOAC, VKA, or antiplatelet therapy...

Two distinct Phytophthora taxa were found to be associated with brown rot of pomelo (Citrus grandis), a new disease of this ancestral Citrus species, in the Vinh Long province, Mekong River Delta area, southern Vietnam. On the basis of morphological characters and using the ITS1-5.8S-ITS2 region of the rDNA and the cytochrome oxidase subunit 1 (COI) as barcode genes, one of the two taxa was provisionally named as Phytophthora sp. prodigiosa, being closely related to but distinct from P. insolita, a species in Phytophthora Clade 9, while the other one, was closely related to but distinct from the Clade 2 species P...

Most alphaviruses are transmitted by arthropods and infect vertebrate hosts. An exception is Eilat virus (EILV), the only described alphavirus with a host range restricted to insects. We established a new generic reverse transcription PCR assay for alphaviruses and tested 8860 tropical mosquitoes. We detected a novel alphavirus, tentatively named Taï Forest alphavirus (TALV), in Culex decens mosquitoes collected in Ivory Coast. The full genome was sequenced, and closest similarity was found to EILV. Pairwise amino acid identities to EILV ranged between 67 and 88 % for the corresponding proteins, suggesting that TALV defines a proposed new alphavirus species...

OBJECTIVES: Burst spinal cord stimulation (SCS) has been reported to reduce back pain and improve functional capacity in Failed Back Surgery Syndrome (FBSS). However, its mechanism of action is not completely understood. Systemic circulating cytokines have been associated with the development of chronic back pain. METHODS: This prospective, feasibility study enrolled 12 refractory FBSS patients with predominant back pain (70% of overall pain) suitable for Burst SCS...

REVIEW
Sandra Malmgren Hill, Sarah Hanzén, Thomas Nyström
The accumulation of damaged and aggregated proteins is a hallmark of aging and increased proteotoxic stress. To limit the toxicity of damaged and aggregated proteins and to ensure that the damage is not inherited by succeeding cell generations, a system of spatial quality control operates to sequester damaged/aggregated proteins into inclusions at specific protective sites. Such spatial sequestration and asymmetric segregation of damaged proteins have emerged as key processes required for cellular rejuvenation...

The recently described taxon Negevirus is comprised of a diverse group of insect-specific viruses isolated from mosquitoes and phlebotomine sandflies. In this study, a comprehensive genetic characterization, molecular, epidemiological and evolutionary analyses were conducted on nearly full-length sequences of 91 new negevirus isolates obtained in Brazil, Colombia, Peru, Panama, USA and Nepal. We demonstrated that these arthropod restricted viruses are clustered in two major phylogenetic groups with origins related to three plant virus genera (Cilevirus, Higrevirus and Blunevirus)...

BACKGROUND: Available incidence data for invasive salmonella disease in sub-Saharan Africa are scarce. Standardised, multicountry data are required to better understand the nature and burden of disease in Africa. We aimed to measure the adjusted incidence estimates of typhoid fever and invasive non-typhoidal salmonella (iNTS) disease in sub-Saharan Africa, and the antimicrobial susceptibility profiles of the causative agents. METHODS: We established a systematic, standardised surveillance of blood culture-based febrile illness in 13 African sentinel sites with previous reports of typhoid fever: Burkina Faso (two sites), Ethiopia, Ghana, Guinea-Bissau, Kenya, Madagascar (two sites), Senegal, South Africa, Sudan, and Tanzania (two sites)...

As compared to conventional high-performance liquid chromatography (HPLC) techniques, nanoflow HPLC exhibits improved sensitivity and limits of detection. However, nanoflow HPLC suffers from low throughput due to instrument failure (e.g., fitting fatigue and trapping column failure), limiting the utility of the technique for clinical and industrial applications. To increase the robustness of nanoflow HPLC, we have developed and tested a trapping column exchanging robot for autonomous interchange of trapping columns...

Colorectal carcinoma represents a heterogeneous entity, with only a fraction of the tumours responding to available therapies, requiring a better molecular understanding of the disease in precision oncology. To address this challenge, the OncoTrack consortium recruited 106 CRC patients (stages I-IV) and developed a pre-clinical platform generating a compendium of drug sensitivity data totalling >4,000 assays testing 16 clinical drugs on patient-derived in vivo and in vitro models. This large biobank of 106 tumours, 35 organoids and 59 xenografts, with extensive omics data comparing donor tumours and derived models provides a resource for advancing our understanding of CRC...

By moving essential body fluids and molecules, motile cilia and flagella govern respiratory mucociliary clearance, laterality determination and the transport of gametes and cerebrospinal fluid. Primary ciliary dyskinesia (PCD) is an autosomal recessive disorder frequently caused by non-assembly of dynein arm motors into cilia and flagella axonemes. Before their import into cilia and flagella, multi-subunit axonemal dynein arms are thought to be stabilized and pre-assembled in the cytoplasm through a DNAAF2-DNAAF4-HSP90 complex akin to the HSP90 co-chaperone R2TP complex...

INTRODUCTION: Numerous micronutrients have immunomodulatory roles that may influence risk of tuberculosis (TB), but the association between baseline micronutrient deficiencies and incident TB after antiretroviral (ART) initiation in HIV-infected individuals is not well characterized. METHODS: We conducted a case-cohort study (n=332) within a randomized trial comparing three ART regimens in 1571 HIV treatment-naïve adults from nine countries. A subcohort of 30 patients was randomly selected from each country (n=270)...

The Research Domain Criteria (RDoC) matrix has been developed to reorient psychiatric research towards measurable behavioral dimensions and underlying mechanisms. Here we used a new genetic rat model with a loss of function point mutation in the dopamine transporter (DAT) gene (Slc6a3_N157K) to systematically study the RDoC matrix (www.nimh.nih.gov/research-priorities/rdoc/constructs/rdoc-matrix.shtml). First, we examined the impact of the Slc6a3_N157K mutation on monoaminergic signaling. We then performed behavioral tests representing each of the five RDoC domains - negative and positive valence systems, cognitive, social, and in arousal/regulatory systems...

Man9GlcNAc2 (Man-9) present at the surface of HIV constitutes the binding sites of several HIV neutralizing agents and mammalian lectin DC-SIGN that is involved in cellular immunity and trans-infections. We describe the conformational properties of Man-9 in free state and when bound by an HIV entry inhibitor protein and define the minimum epitopes of two HIV binding proteins using NMR spectroscopy. In this regard we developed a robust expression system for production of 13C,15N-labeled glycans in mammalian cells that facilitated the implementation of 3D 13C-edited spectra to deconvolute spectral overlap allowing for the solution structure determination of Man-9...

Bipolar disorder (BD) is a highly heritable neuropsychiatric disease characterized by recurrent episodes of mania and depression. BD shows substantial clinical and genetic overlap with other psychiatric disorders, in particular schizophrenia (SCZ). The genes underlying this etiological overlap remain largely unknown. A recent SCZ genome wide association study (GWAS) by the Psychiatric Genomics Consortium identified 128 independent genome-wide significant single nucleotide polymorphisms (SNPs). The present study investigated whether these SCZ-associated SNPs also contribute to BD development through the performance of association testing in a large BD GWAS dataset (9747 patients, 14278 controls)...

Posttranscriptional gene regulation by microRNAs (miRNAs) contributes to the induction and maintenance of prostate carcinoma (PCa). To identify mRNAs enriched or removed from Ago2-containing RISC complexes, these complexes were immunoprecipitated from normal prostate fibroblasts (PNFs) and the PCa line DU145 and the bound mRNAs were quantified by microarray. The analysis of Ago complexes derived from PNFs or DU145 confirmed the enrichment or depletion of a variety of mRNAs already known from the literature to be deregulated...
