Diagnostic Performance of Clinical and Routine Laboratory Data in Acute Mesenteric Arterial Occlusion-An International Multicenter Study.

Background: There are no clinical or laboratory markers that can diagnose acute mesenteric ischemia (AMI) accurately. This study aimed to find differences in clinical and laboratory markers between arterial occlusive AMI and other acute abdominal diseases where AMI was initially suspected.

Methods: This was a post hoc study of an international prospective multicenter study where data on patients with suspected AMI were collected.

A comparative study of Cu-based nanoparticles and their spin-coated films: photocatalytic degradation mechanisms and efficiencies towards malachite green and neutral red azo dyes.

In this work, a comparison of the photocatalytic activity of free-standing Cu-based nanoparticle mixtures and spin-coated nanoparticle films under visible-light radiation is conducted. Herein, CuO, CuO-Cu, CuO-CuN-Cu, and CuN-Cu nanoparticle mixtures were successfully synthesized by a non-aqueous sol-gel route and then deposited on a glass substrate by spin-coating. The surface chemistry of the nanoparticles studied by X-ray photoelectron spectroscopy (XPS) allowed elucidating the nanoparticle synthesis mechanism.

Outcome of Liver Retransplantation in Patients With Primary Sclerosing Cholangitis.

Background And Aims: Primary sclerosing cholangitis (PSC) is among the most common indications for liver transplantation in the Nordic countries and with an increasing trend in Europe and North America. Due to post-transplant complications and high prevalence of disease recurrence this group is at risk of requiring retransplantation (re-LTX). Results from re-LTX for PSC are not extensively studied and there is a lack of knowledge regarding prognosis after re-LTX in this population.

Greening of a boreal rich fen driven by CO fertilisation.

Boreal peatlands store vast amounts of soil organic carbon (C) owing to the imbalance between productivity and decay rates. In the recent decades, this carbon stock has been exposed to a warming climate. During the past decade alone, the Arctic has warmed by ∼ 0.

Use of Estonian Biobank data and participant recall to improve Wilson's disease management.

Population-based biobanks enable genomic screening to support initiatives that prevent disease onset or slow its progression and to estimate the prevalence of genetic diseases in the population. Wilson's disease (WD) is a rare genetic copper-accumulation disorder for which timely intervention is crucial, as treatment is readily available. We studied WD in the Estonian Biobank population to advance patient screening, swift diagnosis, and subsequent treatment.

A European aerosol phenomenology - 9: Light absorption properties of carbonaceous aerosol particles across surface Europe.

Carbonaceous aerosols (CA), composed of black carbon (BC) and organic matter (OM), significantly impact the climate. Light absorption properties of CA, particularly of BC and brown carbon (BrC), are crucial due to their contribution to global and regional warming. We present the absorption properties of BC (b) and BrC (b) inferred using Aethalometer data from 44 European sites covering different environments (traffic (TR), urban (UB), suburban (SUB), regional background (RB) and mountain (M)).

Black Holes and Gravitational Waves from Slow First-Order Phase Transitions.

Slow first-order phase transitions generate large inhomogeneities that can lead to the formation of primordial black holes. We show that the gravitational wave spectrum then consists of a primary component sourced by bubble collisions and a secondary one induced by large perturbations. The latter gives the dominant peak if β/H_{0}<12, impacting, in particular, the interpretation of the recent pulsar timing array data.

Recent advances in asymmetric synthesis cyclopropanol intermediates.

Cyclopropanols have attracted significant attention in organic synthesis as versatile three-carbon synthons, as this readily available class of donor-activated cyclopropanes undergoes miscellaneous transformations, either ring-opening or with retention of the cyclopropane ring. This review summarizes stereoselective and stereoretentive transformations suitable for asymmetric synthesis. The utility of cyclopropanols is discussed for two main strategies: (i) substrate-controlled transformations using enantiomerically enriched cyclopropanol intermediates through a traditional approach, and (ii) the use of nonchiral or racemic cyclopropanols, where asymmetric induction is achieved through a chiral catalyst, representing a direction that has recently emerged.

Diagnosing missed cases of spinal muscular atrophy in genome, exome, and panel sequencing datasets.

Purpose: We set out to develop a publicly available tool that could accurately diagnose spinal muscular atrophy (SMA) in exome, genome or panel sequencing datasets aligned to a GRCh37, GRCh38, or T2T reference genome.

Methods: The SMA Finder algorithm detects the most common genetic causes of SMA by evaluating reads that overlap the c.840 position of the SMN1 and SMN2 paralogs.

A decision-making tool for navigating extracellular vesicle research and product development.

Due to their intercellular communication properties and involvement in a wide range of biological processes, extracellular vesicles (EVs) are increasingly being studied and exploited for different applications. Nevertheless, their complex nature and heterogeneity, as well as the challenges related to their purification and characterization procedures, require a cautious assessment of the qualitative and quantitative parameters that need to be monitored. This translates into a multitude of choices and putative solutions that any EV researcher must confront in both research and translational environments.

Automated generation of process simulation scenarios from declarative control-flow changes.

Business process simulation is an established approach to estimate the potential impact of hypothetical changes on a process, particularly in terms of time and cost-related performance measures. To overcome the complexity associated with manually specifying and fine-tuning simulation models, data-driven simulation (DDS) methods enable users to discover accurate business process simulation models from event logs. However, in the pursuit of accuracy, DDS methods often generate overly complex models.

Surprising acidity for the methylene of 1,3-indenocorannulenes?

Quantitative assessment of the first acidity constant (p ) for BFC (27.6 in CHCN) and FIC (27.8 in CHCN) shows the methylene protons to be significantly more acidic than those in related cyclopentadiene (32 in CHCN), indene (34 in CHCN), or fluorene (37 in CHCN) and comparable to the methine of 9-perfluorophenylfluorene (28.

Wolfram syndrome (WS) is a rare condition caused by homozygous or compound heterozygous mutations in the WFS1 gene primarily. It is diagnosed on the basis of early-onset diabetes mellitus and optic nerve atrophy. Patients complain of trigeminal-like migraines and show deficits in vibration sensation, but the underlying cause is unknown.

Association of ability to rank sweet and fat taste intensities with sweet and fat food propensity ratios of children, adolescents and adults: the I.Family study.

Purpose: It is assumed that sensory taste perception shapes food choices and impacts dietary intake. However, this has rarely been studied in free living subjects of different age-groups with standardised methods. The present study investigated the association of the ability to rank sweet and fat taste intensities with consumption frequency of sweet and fatty foods in children, adolescents and adults from eight European countries.

Foliage development and resource allocation determine the growth responses of silver birch (Betula pendula) to elevated environmental humidity.

Scenarios for future climate predict an increase in precipitation amounts and frequency of rain events, resulting in higher air humidity and soil moisture at high latitudes, including in northern Europe. We analysed the effects of artificially elevated environmental humidity (air relative humidity and soil moisture) on leaf gas exchange, water relations, growth and phenology of silver birch (Betula pendula) trees growing at the Free Air Humidity Manipulation (FAHM) experimental site situated in the hemiboreal vegetation zone, in eastern Estonia, with no occurring water deficit to the trees. The environmental humidity manipulation did not significantly affect the water relations traits but did affect some leaf gas exchange parameters, growth and phenology of the trees.

Secukinumab (Anti-IL-17A Therapeutic Antibody) Improves Clinical Outcome for a Mixed Endotype CRS.

We identified two CRSwNP patients who had previously failed treatment with an anti-IL-4/IL-13 antibody (dupilumab). Based on their clinical characteristics and blood cytokine levels, we considered them mixed Type II/Type III cases and treated them with an anti-IL-17 antibody (secukinumab). Anti-IL-17 antibody secukinumab was superior in reducing their NPS and SNOT-22 values compared to dupilumab.
