Bias-Induced Ga-O-Ir Interface Breaks the Limits of Adsorption-Energy Scaling Relationships for High-Performing Proton Exchange Membrane Electrolyzers.

Rationally manipulating the in-situ formed catalytically active surface of catalysts remains a significant challenge for achieving highly efficient water electrolysis. Herein, we present a bias-induced activation strategy to modulate in-situ Ga leaching and trigger the dynamic surface restructuring of lamellar Ir@Ga2O3 for the electrochemical oxygen evolution reaction. The in-situ reconstructed Ga-O-Ir interface sustains high water oxidation rates at OER overpotentials.

Gas chromatography-mass spectrometry metabolic profiling and sensory evaluation of greenhouse mangoes (Mangifera indica L. 'Irwin') over multiple harvest seasons.

Compared to outdoor mango cultivation in the tropics, greenhouse cultivation in temperate regions is less reported due to its short history and small scale. Here, we evaluated for the first time the taste-focused quality of greenhouse-grown mangoes (Irwin) by GC-MS metabolic profiling and sensory evaluation for over three years (2021-2023). The relative standard deviation in sensory evaluation scores was approximately 15 % each year.

Identification of Gingival Inflammation Surface Image Features Using Intraoral Scanning and Deep Learning.

Introduction And Aim: The assessment of gingival inflammation surface features mainly depends on subjective judgment and lacks quantifiable and reproducible indicators. Therefore, it is a need to acquire objective identification information for accurate monitoring and diagnosis of gingival inflammation. This study aims to develop an automated method combining intraoral scanning (IOS) and deep learning algorithms to identify the surface features of gingival inflammation and evaluate its accuracy and correlation with clinical indicators.

CADCAM Versus Conventional Denture Bases: Network Meta-Analysis of In Vitro Studies Comparing Accuracy and Surface Properties.

Introduction: This systematic review with network meta-analysis (NMA) analysed the current evidence on in vitro studies comparing trueness of fit, surface roughness, colour stability, surface wettability, water sorption, water solubility, and microbial adhesion between conventional and digital denture bases.

Methods: From inception until December 2023, a systematic search of published in-vitro studies from Scopus, PubMed, and the Cochrane Central Register of Controlled Studies was conducted. The protocol was registered in PROSPERO (CRD42024531416).

Role of the sarcin-ricin loop of 23S rRNA in biogenesis of the 50S ribosomal subunit.

The sarcin-ricin loop (SRL) is one of the most conserved segments of ribosomal RNA (rRNA). Translational GTPases (trGTPases), such as EF-G and EF-Tu and IF2, form contacts with the SRL that are critical for GTP hydrolysis and factor function. Previous studies showed that expression of 23S rRNA lacking the SRL confers a dominant lethal phenotype in E.

Parsimonious versus extensive bleeding score: can we simplify risk stratification after percutaneous coronary intervention and reduce bleeding events by de-escalation of the antiplatelet strategy?

Background And Aims: Due to the multitude of risk factors outlined in the guidelines, personalised dual antiplatelet therapy (DAPT) guidance after percutaneous coronary intervention (PCI) is complex. A simplified method was created to facilitate the use of risk stratification. We aimed to compare the predictive and prognostic value of the 'Zuidoost Nederland Hart Registratie' (ZON-HR) classification for bleeding risk with the PREdicting bleeding Complications In patients undergoing Stent implantation and subsEquent DAPT (PRECISE-DAPT) score and to determine the effect of ticagrelor monotherapy versus DAPT in patients with or without high bleeding risk (HBR).

[Legal requirements for information and their influence on patient satisfaction].

The German Patientenrechtegesetz defines, among other things, medical obligations in connection with the provision of information. To date, the extent to which these legal requirements also influence patient satisfaction with information has not been investigated in Germany.The study employed an anonymized patient survey on satisfaction with information, which was recorded using a validated 10-item questionnaire.

Can spatial self-organization inhibit evolutionary adaptation?

Plants often respond to drier climates by slow evolutionary adaptations from fast-growing to stress-tolerant species. These evolutionary adaptations increase the plants' resilience to droughts but involve productivity losses that bear on agriculture and food security. Plants also respond by spatial self-organization, through fast vegetation patterning involving differential plant mortality and increased water availability to the surviving plants.

Capacity and limitations of microfluidic flow to increase solute transport in three-dimensional cell cultures.

Culturing living cells in three-dimensional environments increases the biological relevance of laboratory experiments, but requires solutes to overcome a diffusion barrier to reach the centre of cellular constructs. We present a theoretical and numerical investigation that brings a mechanistic understanding of how microfluidic culture conditions, including chamber size, inlet fluid velocity and spatial confinement, affect solute distribution within three-dimensional cellular constructs. Contact with the chamber substrate reduces the maximally achievable construct radius by 15%.

Quantifying the configurational complexity of biological systems in multivariate 'complexity space'.

An increasing number of evolutionary studies seek to quantify the morphological complexity of organisms, particularly those comprising serially homologous elements at different hierarchical levels of organization. Numerous operational frameworks have been proposed for doing this, but most focus on one or multiple conflated aspects of what is really a multidimensional concept. Here, we advocate the use of 'complexity spaces': multidimensional spaces defined by different vectors of complexity.

Healthy Lifestyle in the First 1000 Days and Overweight and Obesity Throughout Childhood.

Objectives: Investigate associations of different family healthy lifestyle scores (HLS) during the first 1000 days with childhood overweight and obesity (OWOB).

Methods: Cohort-specific analyses were conducted on participants (n = 25 006) from 4 European birth cohorts (The study on the pre- and early postnatal determinants of child health and development [EDEN], Elfe, France; Generation R, the Netherlands; and Lifeways, Ireland). Three composite HLSs were calculated: a maternal pregnancy HLS based on prepregnancy body mass index (BMI) and diet quality, physical activity, smoking status, and alcohol consumption during pregnancy; a parental pregnancy HLS additionally considering paternal BMI and smoking status; and an infancy HLS based on breastfeeding duration, age of solid food introduction, and exposure to passive smoking.

Cotadutide reversible self-assembly based long-acting injectable depot for sustained delivery of GLP-1 glucagon receptor agonists with controlled burst release.

Cota is a lipidated dual GLP-1 and Glucagon receptor agonist that was investigated for the treatment of various metabolic diseases, it is designed for once daily subcutaneous administration. Invasive daily injections often result in poor patient compliance with chronic disease, and here, we demonstrate an innovative strategy of encapsulating reversible cota self-assembled fibers within an in-situ forming depot of low molecular weight poly(lactic-co-glycolic) acid (LWPLGA) for sustained delivery GLP-1 and Glucagon receptor agonist with controlled burst release. This could be a suitable alternative to other sustained delivery strategies for fibrillating peptides.

A simple model for the analysis of epidemics based on hospitalization data.

An epidemiological model with a minimal number of parameters is introduced and its structural and practical identifiabity is investigated both analytically and numerically. The model is useful when a high percentage of unreported cases is suspected, hence only hospitalization data are used to fit the model parameters and calculate the basic reproductive number R and the effective reproductive number R. As a case study, the model is used to study the initial surge and the Omicron wave of the COVID-19 epidemic in Belgium.

Occurrence and transport of per- and polyfluoroalkyl substances (PFAS) in the leachate of a municipal solid waste landfill in Tehran, Iran (a Middle-eastern megacity).

Per- and polyfluoroalkyl substances (PFAS) are present in a variety of products that are disposed in landfills as waste and end up in landfill leachate which cause severe problems. The primary aim of this study was to detect PFAS in generated leachate in different sections of a process and disposal complex (called Aradkuh) located in Tehran, Iran. Due to techno economic limitations of measuring PFAS in Iran and easiness of measuring physicochemical parameters to determine PFAS concentration as well as better understanding of the mechanisms of these substances releases from landfills, this research aimed to evaluate the potential relationship between these parameters in landfill leachate.

The urinary eccDNA landscape in prostate cancer reveals associations with genome instability and vital roles in cancer progression.

Introduction: Extrachromosomal circular DNA (eccDNA) plays significant roles in cancer progression and prognosis. However, it remains unclear whether cell-free eccDNA, considered more stable than linear DNA, possesses cancer-specific genomic features. Furthermore, the biogenesis and function of eccDNAs are not yet fully understood.

Deep eutectic solvents in analysis, delivery and chemistry of pharmaceuticals.

Deep eutectic solvents (DES) have an emerging scientific role, assisting modern pharmaceutics. They are uniquely supporting the resolution of crucial issues, such as the effective extraction and isolation of bio-actives. They act as media and catalysts for pharmaceutical drug synthesis, and as green solvents and modifiers in pharmaceutical analysis.

Formulation screening of lyophilized mRNA-lipid nanoparticles.

Lipid nanoparticles (LNPs) have demonstrated their therapeutic potential as safe and effective drug delivery systems for nucleic acids during the COVID-19 pandemic. However, one of the main challenges during technical CMC (Chemistry, Manufacturing, and Controls) development is their long-term stability at temperatures of 2-8 °C or higher, which may be improved by the removal of water by lyophilization. In this study, we identified lyo-/cryo-protectants for freeze-dried mRNA-LNP formulations beyond conventional excipients such as sucrose and trehalose as T-modifiers using polyA as a surrogate.

Background: Continuous electroacupuncture pre-conditioning (EPRC) and post-conditioning (EPOC) effectively improve motor dysfunction after acute cerebral ischemia, but they require multiple treatments. Recently, electroacupuncture per-conditioning (EPEC) has demonstrated neuroprotective effects, indicating that this single-session intervention has short-term efficacy.

Objective: To evaluate the effect of EPEC at Huantiao (GB30) on motor recovery in acute cerebral ischemia mice.

Nivolumab plus ipilimumab versus nivolumab in microsatellite instability-high metastatic colorectal cancer (CheckMate 8HW): a randomised, open-label, phase 3 trial.

Background: CheckMate 8HW prespecified dual primary endpoints, assessed in patients with centrally confirmed microsatellite instability-high or mismatch repair-deficient status: progression-free survival with nivolumab plus ipilimumab compared with chemotherapy as first-line therapy and progression-free survival with nivolumab plus ipilimumab compared with nivolumab alone, regardless of previous systemic treatment for metastatic disease. In our previous report, nivolumab plus ipilimumab showed superior progression-free survival versus chemotherapy in first-line microsatellite instability-high or mismatch repair-deficient metastatic colorectal cancer in the CheckMate 8HW trial. Here, we report results from the prespecified interim analysis for the other primary endpoint of progression-free survival for nivolumab plus ipilimumab versus nivolumab across all treatment lines.

Differences between medalists, fourth- to eighth-ranked (T8), and ninth- to 12th/13th-ranked finalists in relative performance (relative to season-best), race time, and section times were determined.

Optimal Strategies for Autologous Fat Grafting in Breast Augmentation and Reconstruction: A Systematic Review and Network Meta-Analysis.

Background: Cell-assisted lipotransfer (CAL) and platelet-rich plasma (PRP)-assisted lipotransfer have been used to overcome the low survival rate of conventional lipotransfer. However, there is still insufficient evidence to determine which technique is the best strategy for autologous fat grafting in breast cosmetic and reconstructive surgery. The present study aimed to compare the efficacy of traditional fat transplantation, CAL, and PRP-assisted lipotransfer.

VAE-Surv: A novel approach for genetic-based clustering and prognosis prediction in myelodysplastic syndromes.

Background And Objectives: Several computational pipelines for biomedical data have been proposed to stratify patients and to predict their prognosis through survival analysis. However, these analyses are usually performed independently, without integrating the information derived from each of them. Clustering of survival data is an underexplored problem, and current approaches are limited for biomedical applications, whose data are usually heterogeneous and multimodal, with poor scalability for high-dimensionality.
