We present a new instrument, "Boreas", a cryogen-free methane (CH4) preconcentration system coupled to a dual-laser spectrometer for making simultaneous measurements of δ13C(CH4) and δ2H(CH4) in ambient air. Excluding isotope ratio scale uncertainty, we estimate a typical standard measurement uncertainty for an ambient air sample of 0.07‰ for δ13C(CH4) and 0.9‰ for δ2H(CH4), which are the lowest r
Scope: This European Society of Clinical Microbiology and Infectious Diseases guideline provides evidence-based recommendations to support a selection of appropriate antibiotic use practices for patients seen in the emergency department (ED) and guidance for their implementation. The topics addressed in this guideline are (a) Do biomarkers or rapid pathogen tests improve antibiotic prescribing and
Combined CDK4/6 inhibitor (CDK4/6i) and endocrine therapy significantly improves outcome for patients with estrogen receptor-positive (ER+) metastatic breast cancer, but drug resistance and thus disease progression inevitably occur. Herein, we aimed to identify genomic alterations associated with combined CDK4/6i and endocrine therapy resistance, and follow the levels of specific mutations in long
Besides thriving on altered glucose metabolism, cancer cells undergo glutaminolysis to meet their energy demands. As the first enzyme in catalyzing glutaminolysis, human kidney-type glutaminase isoform (KGA) is becoming an attractive target for small molecules such as BPTES [bis-2-(5 phenylacetamido-1, 2, 4-thiadiazol-2-yl) ethyl sulfide], although the regulatory mechanism of KGA remains unknown.
Sequential anaerobic/aerobic (A/O) treatment conditions for textile wastewater (WW) are more effective than conventional biological treatment. Anaerobic treatment is essential because anaerobic microbes can first break down complex and recalcitrant compounds, which are difficult to degrade under aerobic conditions. The simpler, more degradable compounds are then further broken down by aerobic micr
In this study, a solar dryer incorporating a flat plate heat exchanger to recover heat from exhaust air was investigated to explore the usability of different types of collectors in the system. Their usability was further evaluated through economic and environmental analyses. Moreover, the thermodynamic performance of the solar dryers was evaluated under two weather conditions in Nepal. Apple dryi
Background: Metabolic-associated steatotic liver disease (MASLD) is a novel term proposed in 2023 to replace non-alcoholic fatty liver disease (NAFLD) with the aim of better reflecting its pathogenesis and clinical manifestations. Vibration-controlled transient elastography (VCTE) is an evidence-based, non-invasive imaging device used to evaluate liver fat deposition and fibrosis. It can effective
An uncharacterized gene encoding a glycoside hydrolase family 43-like enzyme from Clostridium boliviensis strain E-1 was identified from genomic sequence data, and the encoded enzyme, CbE1Xyn43-l, was produced in Escherichia coli. CbE1Xyn43-l (52.9 kDa) is a two-domain endo-β-xylanase consisting of a C-terminal CBM6 and a GH43-like catalytic domain. The positions of the catalytic dyad conserved
Background: Etranacogene dezaparvovec, the first gene therapy approved for haemophilia B treatment, was shown to be superior to treatment with continuous prophylactic factor IX in terms of bleeding protection 18 months after gene therapy in a phase 3 trial. We report post-hoc 24-month efficacy and safety data from this trial to evaluate the longer-term effects of etranacogene dezaparvovec in indiv
A novel phosphine-free ruthenium pincer complex based on an NNN pincer ligand has been prepared and fully characterized. The complex was subsequently employed as an efficient catalyst for the N-methylation of amines and the direct N-methylation of nitroarenes using methanol as a C1 source under mild reaction conditions following the borrowing-hydrogen approach. Both of the catalytic transformation
PURPOSE: Brief Admission by self-referral (BA) is a standardized crisis-management intervention for individuals with self-harm and risk for suicide. This study explored relatives' experiences of BA. Relatives' perspectives may contribute to an increased understanding of the effects of BA given the relatives' role as support and informal caregivers as well as being co-sufferers.METHODS: Fourteen re
Background: Children whose parents have alcohol use problems are at an increased risk of several negative consequences, such as poor school performance, an earlier onset of substance use, and poor mental health. Many would benefit from support programs, but the figures reveal that only a small proportion is reached by existing support. Digital interventions can provide readily accessible support a
Global reconstructions, inclusive of environments and ecosystems, and biodiversity counts for the Devonian Period are often done so at the expense of high latitude regions given a historical lack of data presented from these areas. This has bearing on the recognition of biocrises (events marked by extinctions and faunal turnovers) at high latitudes as well as their controls and potential correlati
Ultra-high-frequency ultrasound (UHFUS) has a reported potential to differentiate between aganglionic and ganglionic bowel wall, referred to as histoanatomical differences. A good correlation between histoanatomy and UHFUS of the bowel wall has been proven. In order to perform more precise and objective histoanatomical morphometrics, the main research objective of this study was to develop a compu
GJ 367 is a bright (V ≈ 10.2) M1 V star that has been recently found to host a transiting ultra-short period sub-Earth on a 7.7 hr orbit. With the aim of improving the planetary mass and radius and unveiling the inner architecture of the system, we performed an intensive radial velocity follow-up campaign with the HARPS spectrograph—collecting 371 high-precision measurements over a baseline of nea
A search for pair-produced vector-like quarks using events with exactly one lepton (e or μ), at least four jets including at least one b-tagged jet, and large missing transverse momentum is presented. Data from proton–proton collisions at a centre-of-mass energy of s= 13 TeV , recorded by the ATLAS detector at the LHC from 2015 to 2018 and corresponding to an integrated luminosity of 139 fb - 1 ,
Context: For nonazoospermic infertile men with elevated sperm DNA fragmentation (SDF), it is unclear whether the use of testicular sperm for intracytoplasmic sperm injection (ICSI) may offer advantages over ejaculated sperm. Objective: To determine whether ICSI outcomes (fertilisation rate, pregnancy rate, miscarriage rate, and live birth rate) are better with testicular sperm than with ejaculated
Adjuvant bacillus Calmette-Guérin (BCG) instillations represent a cornerstone in the treatment of non–muscle-invasive bladder cancer. Instillation schedule and dose modifications have been evaluated in efforts to reduce the incidence of adverse events (AEs), but none so far has the same treatment efficacy as the full-dose recommended schedule. It has been shown that prophylactic quinolone use in c
Decentralized water reuse technologies are increasingly being explored as a transformative approach for complementing centralized water and wastewater infrastructure. A transition to onsite water reuse requires a better understanding of how urban infrastructures are governed. While governance tends to be discussed within ideal types─i.e., hierarchy, market, and network─researchers increasingly rec
