Glutamyl-tRNA reductase activity in Bacillus subtilis is dependent on the hemA gene product

The Bacillus subtilis hemAXCDBL operon encodes enzymes for the synthesis of 5-aminolaevulinic acid via the C5 pathway (hemA and hemL) and uroporphyrinogen III (hemB, hemC and hemD). B. subtilis HemA protein (molecular mass 50 kDa) was overexpressed in hemA mutants of both Escherichia coli and B. subtilis. A mutant B. subtilis HemA protein with a Cys to Tyr change at position 105 was also overexpre

Increased Melatonin Signaling Is a Risk Factor for Type 2 Diabetes

Type 2 diabetes (T2D) is a global pandemic. Genome-wide association studies (GWASs) have identified >100 genetic variants associated with the disease, including a common variant in the melatonin receptor 1 b gene (MTNR1B). Here, we demonstrate increased MTNR1B expression in human islets from risk G-allele carriers, which likely leads to a reduction in insulin release, increasing T2D risk. Accordin

Capto™ Resins for Chromatography of DNA : A Minor Difference in Ligand Composition Greatly Influences the Separation of Guanidyl-Containing Fragments

The differences in chromatographic behaviour of individual deoxynucleotides as well as small single-stranded and double-stranded DNA molecules have been examined for two resins from the Capto family: Capto Adhere and Capto Q ImpRes. Capto Adhere carries a multimodal ligand which combines strong anion with aromatic recognition, while Capto Q ImpRes is a strong anion exchanger with a chemically simi

Genome-wide association study of the modified stumvoll insulin sensitivity index identifies BCL2 and FAM19A2 as novel insulin sensitivity loci

Genome-wide association studies (GWAS) have found few common variants that influence fasting measures of insulin sensitivity. We hypothesized that a GWAS of an integrated assessment of fasting and dynamic measures of insulin sensitivity would detect novel common variants. We performed a GWAS of the modified Stumvoll Insulin Sensitivity Index (ISI) within the Meta-Analyses of Glucose and Insulin-Re

Beam Dynamics in the ESS Linac under the Influence of Monopole and Dipole HOMs

The European Spallation Source (ESS), planned to be operational in 2019, is anticipated to be the worlds most intense neutron source. The total beam power will be 5 MW. We focus on the impact of manufacturing errors on the beam quality. In particular we assess the emittance dilution which occurs due to Higher Order Modes (HOMs) excited at a harmonic of the bunch frequency. We also discuss some ali

Targeting human fear of large carnivores — Many ideas but few known effects

This paper reviews the peer-reviewed scientific literature on interventions aimed to reduce human fear of large carnivores in human-large carnivore conflicts. Based on psychological theories, a wide definition of fear was adopted, including fear as an emotion, as a perception and as an attitude. Four major categories of interventions were identified: information and education, exposure to animal a

Analog Integrated Audio Frequency Synthesizer

In this paper we present an audio synthesizer that creates audio signals, intended to be reproduced as sound by a loudspeaker. This paper details the design, implementation and verification of an analog, subtractive audio synthesizer. The synthesizer produces a variety of waveforms spanning approximately 3 octaves. The frequency is controlled by an external voltage and the harmonic content is regu

The Swedish National Innovation Council: Innovation policy governance to replace linearity with holism

The Swedish National Innovation Council (NIC) was created by the Prime Minister (Stefan Löfven) in February 2015, and it has now been operating for 18 months. It is personally chaired by the Prime Minister, which is unusual for such councils in other countries. Another atypical characteristic of the Swedish NIC is its dominant and wide focus on innovation rather than on research (for which there i

Revision of river terrace geochronology in the Orawa-Nowy Targ Depression, south Poland : insights from OSL dating

Geochronologies of intramontane depression (basin) fluvial sedimentation enable to identify through time periods of alluviation and river erosion, and date fault movement. For these purposes the optically stimulated luminescence (OSL) dating has been applied to evaluate and to develop a geochronological framework of river terraces. We study the age of river terrace deposits of the Czarny Dunajec R

RIFM fragrance ingredient safety assessment, isobornyl isovalerate, CAS registry number 7779-73-9

This material was evaluated for genotoxicity, repeated dose toxicity, developmental toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization potential, as well as, environmental safety. Data from the suitable read across analog isobornyl acetate (CAS # 125-12-2) show that this material is not genotoxic, provided a MOE> 100 for the repeated d

Patterns of metastasis in colon and rectal cancer

Investigating epidemiology of metastatic colon and rectal cancer is challenging, because cancer registries seldom record metastatic sites. We used a population based approach to assess metastatic spread in colon and rectal cancers. 49,096 patients with colorectal cancer were identified from the nationwide Swedish Cancer Registry. Metastatic sites were identified from the National Patient Register

Cancer heterogeneity determined by functional proteomics

Current manuscript gives a synopsis of tumor heterogeneity related to patient samples analyzed by proteomics, protein expression analysis and imaging mass spectrometry.First, we discuss the pathophysiologocal background of cancer biology as a multifactorial and challenging diseases. Disease pathology forms the basis for protein target selection. Therefore, histopathological diagnostics and grading

Surface Partitioning in Organic-Inorganic Mixtures Contributes to the Size-Dependence of the Phase-State of Atmospheric Nanoparticles

Atmospheric particulate matter is one of the main factors governing the Earth's radiative budget, but its exact effects on the global climate are still uncertain. Knowledge on the molecular-scale surface phenomena as well as interactions between atmospheric organic and inorganic compounds is necessary for understanding the role of airborne nanoparticles in the Earth system. In this work, surface c
