Macromolecular design and synthesis of hydroxide conducting membranes with high alkaline stability
Today extensive research efforts are devoted to the synthesis and studies of durable anion exchange membranes (AEMs) with the aim to develop alkaline fuel cells and electrolyzers that are able to operate efficiently without platinum group metal catalysts [1]. One of the great challenges is to design and synthesize polymeric AEM materials with high OH– conductivity and the necessary stability under
Continuous Droplet Coalescence in a Microchannel Coflow Using Bulk Acoustic Waves
The coalescence of liquid droplets with a liquid stream has profound importance in various emerging applications, such as biochemical assays. Acoustic force-based droplet manipulation, which offers unique advantages, is consequently gaining attention. However, the physics of acoustics-driven coalescence of liquid droplets with a liquid stream is not well understood. Here, we unravel the mechanism
Intensity-dependent near-threshold ionization of Kr in the vacuum-uv
In this work, we present measurements of the intensity-dependent photoelectron spectrum of Kr irradiated by the FLASH FEL tuned to a photon energy of 25.8 eV. Intensity dependent photoelectron spectra were obtained with the aid of a Velocity Map Imaging (VMI) spectrometer. As the FEL photon energy is close to threshold, two photon sequential double ionization is favoured. The number of open channe
The Rise of Common Ownership: A Call to Arms for Competition Policy?
Breaking the stalemate of sustainable consumption with industrial ecology and a circular economy
Genomics of host-pathogen interactions : challenges and opportunities across ecological and spatiotemporal scales
Evolutionary genomics has recently entered a new era in the study of host-pathogen interactions. A variety of novel genomic techniques has transformed the identification, detection, and classification of both hosts and pathogens, allowing a greater resolution that helps decipher their underlying dynamics and provides novel insights into their environmental context. Nevertheless, many challenges to
The left habenular nucleus contains a discrete serotonin-immunoreactive subnucleus in the coho salmon (Oncorhynchus kisutch)
By use of antibodies against serotonin, a discrete subnucleus of putatively serotoninergic neurons was observed in the dorsal subdivision of the left habenular nucleus in the brain of the coho salmon. The subnucleus was observed in salmon of different life-stages: in fingerlings, during smolt transformation, after smolt transformation (in seawater), and after spawning. This finding further emphasi
Evolutionary aspects of Indo-European gender assignment
Gender assignment in languages with a gender system is a complex issue, as this can be influenced by both semantic, morphological, and phonological factors (Corbett, 1991, 2013; Corbett & Fraser, 2000). Many Indo-European languages possess a three-gender system, which distinguishes masculine, feminine, and neuter gender. Whereas this system is preserved in several Indo-European branches, it ha
Free Ports for Art: Special Tax Zones as Cultural Policy Incentives?
A free port for art is a location in a country with purpose-built art facilities where imported works of art may be stored without taxes such as value added tax (VAT), goods and services tax (GST), consumption tax, transaction taxes and customs duties. As long as the art does not leave the free port, such taxes are not imposed, hence the word “free”. These free ports could be regarded as special t

Metabolite-related dietary patterns and the development of islet autoimmunity
The role of diet in type 1 diabetes development is poorly understood. Metabolites, which reflect dietary response, may help elucidate this role. We explored metabolomics and lipidomics differences between 352 cases of islet autoimmunity (IA) and controls in the TEDDY (The Environmental Determinants of Diabetes in the Young) study. We created dietary patterns reflecting pre-IA metabolite difference
Aged garlic extract preserves cutaneous microcirculation in patients with increased risk for cardiovascular diseases : A double-blinded placebo-controlled study
Laser Doppler velocimetry estimates tissue perfusion providing a record of microvascular blood flow. Patients with heart disease or diabetes mellitus have impaired microvascular perfusion leading to impaired wound healing. Aged garlic extract (AGE) has a positive effect on vascular elasticity. This study aimed to assess the effect of long-term treatment with AGE on cutaneous tissue perfusion. A to
The hippocampus in families with schizophrenia in relation to obstetric complications
Background: Hippocampal volume reduction is a well replicated finding in schizophrenia. Evidence indicates a contribution of genetic and environmental factors, especially the influence of obstetric complications to this volume reduction. The aim of this study was to compare hippocampal volume of schizophrenic patients as well as and their relatives with control subjects and to quantify the additio
The origins of Nostra Aetate, with a special regard to the Jewish contributions
Magdalena Dziaczkowska analyzes the process of drafting of the Nostra Aetate (1965), the declaration on the relation of the Church with non-Christian Religions of the Second Vatican Council. Her interest focuses particularly on the Jewish contributions to this document.
Genome-wide study on uveal melanoma patients finds association to DNA repair gene TDP1
Uveal melanoma is a life-threatening disease for which data on germline predisposition are essentially limited to mutations in the BAP1 gene. Many risk factors are shared between uveal melanoma and cutaneous melanoma, and these include fair skin color and light eye color. We carried out a genome-wide association study on 590 uveal melanoma patients and 5199 controls. Using a P-value limit of 10 we
Identification of the atypical L-type Ca2+ channel blocker diltiazem and its metabolites as ghrelin receptor agonists
Using a high-throughput functional screen, the atypical L-type Ca 2+ channel blocker diltiazem was discovered to be an agonist at the human ghrelin (GHSR1a) receptor. In cellular proliferation, Ca2+ mobilization, and bioluminescence resonance energy transfer (BRET-2) assays, diltiazem was a partial agonist at GHSR1a receptors, with 50 to 80% relative efficacy compared with the GHSR1a peptide agoni
Alkylative cleavage of the endo-cyclic C-O bond in lactol ethers employing organometallic reagents
Simple lactol ethers undergo ring cleavage to give acyclic chain-extended products on treatment with organoaluminium and organotitanium reagents.
Development of tyrosine hydroxylase-, dopamine- and dopamine β-hydroxylase-immunoreactive neurons in a teleost, the three-spined stickleback
The development of catecholaminergic neuronal systems in the brain of a teleost, the three-spined stickleback, was studied through embryonic to early larval stages by immunocytochemistry using specific antibodies against dopamine, tyrosine hydroxylase and dopamine β-hydroxylase. By analysing the spatiotemporal patterns of development for the catecholaminergic nuclei, possible homologies with nucle
