Matrix Redox Physiology Governs the Regulation of Plant Mitochondrial Metabolism through Posttranslational Protein Modifications

Mitochondria function as hubs of plant metabolism. Oxidative phosphorylation produces ATP, but it is also a central high-capacity electron sink required by many metabolic pathways that must be flexibly coordinated and integrated. Here, we review the crucial roles of redox-associated posttranslational protein modifications (PTMs) in mitochondrial metabolic regulation. We discuss several major conce

Higher burden of supraventricular ectopic complexes early after catheter ablation for atrial fibrillation is associated with increased risk of recurrent atrial fibrillation

Early identification of patients who could benefit from early re-intervention after catheter ablation is highly warranted. Our aim was to investigate the association between post-procedural burden of supraventricular ectopic complexes (SVEC) and the risk of long-term atrial fibrillation (AF) recurrence. A total of 125 patients undergoing catheter ablation for AF were included. Patients underwent 7

On-line compositional measurements of AuAg aerosol nanoparticles using optical emission from spark ablation

Spark ablation is an established method for generating aerosol nanoparticles. By changing the electrodes, synthesis of monometallic, multimetallic and semiconducting nanoparticles has been demonstrated. Apart from using electrodes of specific composition, compositional tuning of bimetallic nanoparticles during synthesis has recently been demonstrated (Kohut, et al., 2021). In many applications, it

Use phase and end-of-life modeling of biobased biodegradable plastics in life cycle assessment : a review

Due to the negative environmental impacts along the life cycle of fossil-based plastics, there is an increased interest in the development of biobased and biodegradable plastics. Especially, biodegradable bioplastics possess different material characteristics than fossil-based plastics and can therefore be expected to perform differently during the product use and in end-of-life (EOL) phases. Thus

Design and characterization of matrix metalloproteinase-responsive hydrogels for the treatment of inflammatory skin diseases

Enzyme-responsive hydrogels, formed by step growth photopolymerization of biscysteine peptide linkers with alkene functionalized polyethylene glycol, provide interesting opportunities as biomaterials and drug delivery systems. In this study, we developed stimuli-responsive, specific, and cytocompatible hydrogels for delivery of anti-inflammatory drugs for the treatment of inflammatory skin disease

Measurement of the polarisation of single top quarks and antiquarks produced in the t-channel at √s = 13 TeV and bounds on the tWb dipole operator from the ATLAS experiment

A simultaneous measurement of the three components of the top-quark and top-antiquark polarisation vectors in t-channel single-top-quark production is presented. This analysis is based on data from proton–proton collisions at a centre-of-mass energy of 13 TeV corresponding to an integrated luminosity of 139 fb−1, collected with the ATLAS detector at the LHC. Selected events contain exactly one iso

A global synthesis of offspring size variation, its eco-evolutionary causes and consequences

1.Offspring size is a key functional trait that can affect all phases of the life history, from birth to reproduction, and is common to all the Metazoa. Despite its ubiquity, reviews of this trait tend to be taxon‐specific. We explored the causes and consequences of offspring size variation across plants, invertebrates and vertebrates.2.We find that offspring size shows clear latitudinal patterns Offspring size is a key functional trait that can affect all phases of the life history, from birth to reproduction, and is common to all the Metazoa. Despite its ubiquity, reviews of this trait tend to be taxon-specific. We explored the causes and consequences of offspring size variation across plants, invertebrates and vertebrates. We find that offspring size shows clear latitudinal patterns amo

Anisotropic flow of identified particles in Pb-Pb collisions at √sNN=5.02 TeV

The elliptic (v2), triangular (v3), and quadrangular (v4) flow coefficients of π±, K±, p+p¯,Λ+Λ¯,KS0, and the ϕ-meson are measured in Pb-Pb collisions at sNN=5.02 TeV. Results obtained with the scalar product method are reported for the rapidity range |y| < 0.5 as a function of transverse momentum, pT, at different collision centrality intervals between 0–70%, including ultra-central (0–1%) collis

A Simple Method of Genomic DNA Extraction from Human Samples for PCR-RFLP Analysis

Isolation of DNA from blood and buccal swabs in adequate quantities is an integral part of forensic research and analysis. The present study was performed to determine the quality and the quantity of DNA extracted from four commonly available samples and to estimate the time duration of the ensuing PCR amplification. Here, we demonstrate that hair and urine samples can also become an alternate sou

Clinical utility and impact of the use of the chromogenic vs one-stage factor activity assays in haemophilia A and B

Treatment of haemophilia A/B patients comprises factor VIII (FVIII) or factor IX (FIX) concentrate replacement therapy, respectively. FVIII and FIX activity levels can be measured in clinical laboratories using one-stage activated partial thromboplastin time (aPTT)-based clotting or two-stage chromogenic factor activity assays. We discuss strengths and limitations of these assays, providing exampl

Preclinical evidence for the role of stem/stromal cells in COPD

Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death worldwide and there are currently limited treatment options for these patients. The disease is characterized by a reduction in airflow due to chronic bronchitis, as well as airspace enlargement in the distal lung, resulting in a loss of surface area available for gas exchange. At end-stage disease, oxygen therapy an

In-situ electrochemical synthesis of heteroatoms-doped reduced graphene oxide toward nonradical degradation of tetracycline

Nonradical-based advanced oxidation processes (AOPs) catalyzed by defective carbonaceous materials have exhibited great superiorities in trace antibiotics removal from natural water matrices. However, the complicated, extensive and highly-energy consumed synthesis methods are seriously hindering its development and application. Herein an in-situ electrochemical synthesis technology was developed a

Genetic traces of hybrid zone movement across a fragmented habitat

Theoretical and empirical studies suggest that the structure and position of hybrid zones can change over time. Evidence for moving hybrid zones has been directly inferred by repeated sampling over time, or indirectly through the detection of genetic footprints left by the receding species and the resulting asymmetric patterns of introgression across markers. We here investigate a hybrid zone form
