Etiology and Clinical Prediction of Community-Acquired Lower Respiratory Tract Infection in Children.

Background: Community acquired lower respiratory tract infection (LRTI) is a leading cause for hospitalization in children and important cause for antibiotic prescription. We aimed to describe the aetiology of LRTI in children and analyse factors associated with bacterial or viral infection.

Methods: Patients aged < 19 years with a diagnosis of LRTI were identified from the Observational Medical Outcomes Partnership Common Data Model Database of Seoul National University Bundang Hospital from January 2005-July 2019, and their clinical characteristics were obtained from the electronic medical records and retrospectively reviewed.

Sirt1 Regulates Phenotypic Transformation of Diabetic Cardiac Fibroblasts through Akt/Α-SMA Pathway.

Aims: Cardiac fibrosis causes most pathological alterations of cardiomyopathy in diabetes and heart failure patients. The activation and transformation of cardiac fibroblasts (CFs) are the main pathological mechanisms of cardiac fibrosis. It has been established that Sirtuin1 (Sirt1) plays a protective role in the pathogenesis of cardiovascular disorders.

Amorphization Stabilizes Te-based Aqueous Batteries via Confining Free Water.

Tellurium (Te), with its rich valence states (-2 to +6), could endow aqueous batteries with potentially high specific capacity. However, achieving complete and stable hypervalent Te0/Te4+ electrochemistry in an aqueous environment poses significant challenges, owing to the sluggish reduction kinetics, the easy dissolution of Te4+ species, and a controversial energy storage mechanism. Herein, for the first time, we demonstrate an amorphous strategy for robust aqueous TeO2/Te electrochemistry.

In a Different Light: Irradiation-Induced Cuticular Wax Accumulation Fails to Reduce Cuticular Transpiration.

The cuticle, an extracellular hydrophobic layer impregnated with waxy lipids, serves as the primary interface between plant leaves and their environment and is thus subject to external cues. A previous study on poplar leaves revealed that environmental conditions outdoors promoted the deposition of about 10-fold more cuticular wax compared to the highly artificial climate of a growth chamber. Given that light was the most significant variable distinguishing the two locations, we hypothesized that the quantity of light might serve as a key driver of foliar wax accumulation.

Zero-Valent Copper Catalysis Enables Regio- and Stereoselective Difunctionalization of Alkynes.

The development of a metallic copper-based catalyst system remains a significant challenge. Herein, we report the synthesis of highly stable, active, and reusable Cu0 catalyst for the carboboration of alkynes using carbon electrophiles and bis(pinacolato)diboron (B2pin2) as chemical feedstocks to afford di- and trisubstituted vinylboronate esters in a regio- and stereoselective manner with appreciable turnover number (TON) of up to 2535 under mild reaction conditions. This three-component coupling reaction works well with a variety of substituted electrophiles and alkynes with broad functional group tolerance.

[Calling for attention to prevention and treatment of infection in children during the fall-winter seasons].

(MP) is a common cause of community-acquired pneumonia in children in China, and it is often prevalent in the autumn and winter seasons. In the autumn and winter of 2023, a large-scale epidemic outbreak of MP pneumonia occurred nationwide in the pediatric population, which brought harm to child health, caused a heavy disease burden, imposed a challenge to the pediatric medical service system, and aroused great attention from medical administration and public health fields. The widespread prevalence of macrolide-resistant MP (MRMP) in China has become a prominent problem in pediatric clinical practice.

Open frameworks in the NaMn(PO)F fluoro-pyrophosphates system.

Three new sodium manganese fluoro-pyrophosphate compounds, namely, NaMn(PO)F (I), NaMn(PO)F (II), and NaMn(PO)F (III), have been synthesized by heating a mixture of NaPF, NaPOF or NaHPO with different Mn sources in NaNO and KNO fluxes. The structures of the title compounds were characterized single-crystal X-ray diffraction (XRD). II is characteristic of a shell of Na ions that encloses one [Mn(PO)F] unit, whereas I and III reveal three-dimensional (3D) frameworks that consist of MnO, Mn/NaOF octahedra or MnO octahedra and distorted MnO square pyramids with PO units, where Na cations reside in different-membered ring one-dimensional (1D) tunnels.

Early Initiation of Bundle Sheath Cells During Leaf Development as Visualised by SCARECROW Expression in Dicotyledonous C Plants.

The C type of dicotyledonous plants exhibit a higher density of reticulate veins than the C type, with a nearly 1:1 ratio of mesophyll cells (MCs) to bundle sheath cells (BSCs). To understand how this C-type cell pattern is formed, we identified two SCARECROW (SCR) genes in C Flaveria bidentis, FbSCR1 and FbSCR2, that fully or partially complement the endodermal cell layer-defective phenotype of Arabidopsis scr mutant. We then created FbSCRs promoter β-glucuronidase reporter (GUS) lines of F.

Public Involvement to Enhance Care Home Research; Collaboration on a Minimum Data Set for Care Homes.

Introduction: Information on care home residents in England is captured in numerous data sets (care home records, General Practitioner records, community nursing, etc.) but little of this information is currently analysed in a way that is useful for care providers, current or future residents and families or that realises the potential of data to enhance care provision. The DACHA study aimed to develop and test a minimum data set (MDS) which would bring together data that is useful to support and improve care and facilitate research.

Donor-Acceptor Type Carbon Nitride Photocatalysts in Photocatalysis: Current Understanding, Applications and Challenges.

The exploration of photocatalytic materials with efficient charge separation has always been a prominent area of research in photocatalysis. In the preceding years, the strategy of constructing donor-acceptor (D-A) structured materials has gradually been developed in photocatalytic systems, becoming a new research crossroads and attracting extensive interdisciplinary focus. Polymeric carbon nitride (PCN) has gradually been recognized as the primary photocatalytic material for constructing D-A structures due to its attractive exceptional physicochemical stability, electronic band structure, and cost-effectiveness.

The differences in the distribution characteristics and prognostic value of tumor-infiltrating T lymphocyte subsets between lung adenocarcinoma and lung squamous cell carcinoma.

This study aims to compare the distributions of cluster of differentiation (CD) 4+ and CD4+ T cell subsets of TILs and their clinical significance between lung adenocarcinoma (LUAD) and lung squamous cell carcinoma (LUSC).

Methods: The tumor tissues of 78 LUAD and 56 LUSC patients who underwent surgery at The Second Affiliated Hospital of Zhengzhou University between October 2020 and October 2022 were collected, TIL level were detected by pathological observation, and the proportions of CD4+, CD4+ T cell subsets and CD4+/CD4+ ratio in TILs were detected by flow cytometry.

Efficient and Scalable Direct Regeneration of Spent Layered Cathode Materials via Advanced Oxidation.

Among direct recycling methods for spent lithium-ion batteries, solid-state regeneration is the route with minimal bottlenecks for industrial application and is highly compatible with the current industrial cathode materials production processes. However, surface structure degradation and interfacial impurities of spent cathodes significantly hinder Li replenishment during restoration. Herein, we propose a unique advanced oxidation strategy that leverages the inherent catalytic activity of spent layered cathode materials to address these challenges.

Seed pretreatment with cloquintocet-mexyl protects wheat seedlings from fomesafen injury by promoting photosynthesis and decreasing oxidative stress.

Background: Fomesafen is a selective herbicide widely used to control post-emergent broad-leaf weeds in soybean and peanut fields. Because of its persistent nature in soil, it can suppress subsequent crops, including wheat. There is limited information focusing on methods of protecting wheat from fomesafen injury by soil residue.

Zero-Waste Polyanion and Prussian Blue Composites toward Practical Sodium-Ion Batteries.

Closed-loop transformation of raw materials into high-value-added products is highly desired for the sustainable development of the society but is seldom achieved. Here, a low-cost, solvent-free and "zero-waste" mechanochemical protocol is reported for the large-scale preparation of cathode materials for sodium-ion batteries (SIBs). This process ensures full utilization of raw materials, effectively reduces water consumption, and simplifies the operating process.

Surface-Enhanced Raman Spectroscopy for Nitrite Detection.

Nitrite is an important chemical intermediate in the nitrogen cycle and is ubiquitously present in environmental and biological systems as a metabolite or additive in the agricultural and food industries. However, nitrite can also be toxic in excessive concentrations. As such, the development of quick, sensitive, and portable assays for its measurement is desirable.

Identifying genetic differences between bipolar disorder and major depression through multiple genome-wide association analyses.

Background: Accurate diagnosis of bipolar disorder (BPD) is difficult in clinical practice, with an average delay between symptom onset and diagnosis of about 7 years. A depressive episode often precedes the first manic episode, making it difficult to distinguish BPD from unipolar major depressive disorder (MDD).

Aims: We use genome-wide association analyses (GWAS) to identify differential genetic factors and to develop predictors based on polygenic risk scores (PRS) that may aid early differential diagnosis.

Predicting Color Development and Texture Changes in Tomatoes Treated With Hot Water and Exposed to High-Temperature Ethylene Using Support Vector Regression.

This study investigated the impacts of hot water treatment (HWT) at 50°C or 25°C for 5 min and high-temperature ethylene (HTE) exposure at varying temperatures (20°C, 30°C, or 35°C) and durations (24, 48, or 72 h) on the postharvest quality and antioxidant properties of mature green tomatoes (MG). Color changes, physicochemical characteristics, antioxidant compounds, and overall antioxidant ability were assessed. HWT increased β-carotene levels and oxygen radical absorbance capacity (ORAC) while preserving color metrics, despite later HTE exposure.

Conservation genomics within government led conservation planning: an Australian case study exploring cost and benefit for threatened flora.

The importance of conserving plant genetic diversity has been recognised since the 1980's, but genetic research tools for improving conservation remain largely absent from standard planning. Using an Australian case study framework of the New South Wales Government's Saving our Species program, we outline the costs and benefits associated with conducting genomic analysis within a conservation strategy to inform for example, taxonomic resolution, targeted monitoring, translocations and ex situ collections. Despite a reported sentiment that costs are prohibitive, our study identified that where genetics reports have been provided (32 to date), the cost of genetic sampling, analysis and advice is less than 10% of the total Government investment (SoS program) and will continue decreasing proportionally throughout the years as other management occurs.
