A study on the mechanical and economic performance comparison of ceramsite concrete based on fiber selection and optimization.

To improve the toughness and strength of ceramsite concrete, this study employed three different types of fibers to enhance its performance. It prepared 8 sets of specimens, conducted stress-strain curve and static strength tests, and calculated various performance parameters. Through analysis of the economic performance and failure modes, it is found that high-toughness polypropylene fibers and steel fibers significantly enhanced both the strength and toughness of ceramsite concrete, while carbon fibers, although capable of increasing strength, do not improve toughness.

Hotspots of nitrogen losses from anthropogenic sources in the Huang-Huai-Hai Basin, China.

Poor management of nitrogen (N) can lead to serious environmental problems, such as air and water pollution. The accurate identification of priority control areas and emission sources is critical for making effective decisions regarding sustainable N management. This study aimed to identify hotspots for N losses and quantitatively analyze the relative contributions of different emission sources in the Huang-Huai-Hai Basin at the county scale.

Stacking Configurations of Triangular Au and Tetrahedral Au Units in Thiolate-Protected Gold Nanoclusters: Insights into Structural Stability and Growth Mechanisms.

Triangular Au and tetrahedral Au are key structural units in the face-centered cubic gold core of thiolate-protected gold nanoclusters. Understanding their stacking arrangements is essential for elucidating the growth mechanisms of these gold cores. In this study, we design two new isomers of Au(SR) nanoclusters via deliberately adjusting the stacking pattern of Au and Au based on the grand unified model and ring model to show preferable packing arrangements.

Evaluation of Pharmacokinetics of Lebrikizumab in Healthy Individuals After Subcutaneous Administration Using a Prefilled Syringe or Autoinjector in a Phase 1 Randomized Study.

Purpose: Lebrikizumab is a novel, high-affinity immunoglobulin G4 monoclonal antibody that targets interleukin-13, a central mediator in atopic dermatitis (AD). In previous studies in patients with moderate-to-severe AD, lebrikizumab, administered subcutaneously via a prefilled syringe with a needle safety device (PFS-NSD), demonstrated rapid and durable dose-dependent efficacy. We assessed the pharmacokinetics and safety of lebrikizumab using either a PFS-NSD or an investigational autoinjector.

Optical tuning of the terahertz response of black phosphorus quantum dots: effects of weak carrier confinement.

In contrast to few-layer black phosphorus (BP) with a relatively larger area, BP quantum dots (BP-QDs) are expected to have distinctive electromagnetic response and carrier behaviors, especially in low-frequency range such as in the THz regime. Herein, we experimentally investigate the THz properties of BP-QDs as well as the optical control of these properties. It is demonstrated that the effects of weak carrier confinement, which is associated with diffusive restoring current in each BP-QD, contribute significantly to the effective THz conductivity of BP-QDs.

An Auger electron-loaded theranostic biosensor triggered by the ACE2-mediated virus/host endocytosis.

Accurate diagnosis and effective antiviral strategies are critical to combat acute infection and to avoid damage to the host. Due to their restricted radiation range and energy, Auger electron emitters have shown potential as a RNA-destructing radionuclide therapy in oncology and infection. Focusing on the process of angiotensin-converting enzyme 2 (ACE2)-mediated endocytosis, Technetium-99m-labeled DX600 (Tc-DX600) was synthesized as an Auger electron vector to specifically bind to surface-expressed ACE2 proteins on 293T-hACE2 cells (293T cells stably expressing human ACE2), and Technetium-99m-loaded microvesicles (Tc-MVs) served as an antiviral tracer and effector in pseudovirus infection.

Tissue source may affect the esophageal flora in patients with esophageal squamous cell carcinoma.

The aim of the present study was to provide a theoretical basis for the selection of standard sampling methods in the study of the esophageal microbiota in patients with esophageal squamous cell carcinoma (ESCC) by comparing the differences in bacterial communities between surgical and endoscopic esophageal mucosal tissues. A total of 72 patients with ESCC who were diagnosed at Taihe Hospital (Shiyan, China) between July 2018 and July 2019 were selected to participate in the present study. The sequence V hypervariable region was amplified, and Illumina HiSeq sequencing was performed to analyze the differences between the two groups.

PepCARES: A Comprehensive Advanced Refinement and Evaluation System for Peptide Design and Affinity Screening.

Peptides are crucial in vaccine research, and their remarkable specificity and efficacy make them a promising potential drug class. However, designing and screening these peptides computationally is challenging. Here, we present the comprehensive advanced refinement and evaluation system (PepCARES), a program utilizing our novel model called PeptideMPNN and score evaluation for peptide design and affinity screening.

A multiband NIR upconversion core-shell design for enhanced light harvesting of silicon solar cells.

Exploring lanthanide light upconversion (UC) has emerged as a promising strategy to enhance the near-infrared (NIR) responsive region of silicon solar cells (SSCs). However, its practical application under normal sunlight conditions has been hindered by the narrow NIR excitation bandwidth and the low UC efficiency of conventional materials. Here, we report the design of an efficient multiband UC system based on Ln/Yb-doped core-shell upconversion nanoparticles (Ln/Yb-UCNPs, Ln= Ho, Er, Tm).

Peripheral microvessel area better predicts the severity of coronary stenosis of acute myocardial infarction patients over pulse wave velocity.

Microvascular obstruction (MVO) is linked with adverse clinical outcome in acute coronary syndrome (ACS) patients, therefore, early prediction of MVO with non-invasive peripheral microcirculation is crucial in facilitating optimal treatment. Current study aims to analyze the significance of opisthenar microvessel area (OMA, measured using optical coherence tomography, OCT) in predicting coronary stenosis (Gensini score, GS) and short-term cardiac recovery of ACS patients and the results were compared to those of arterial stiffness parameters (Pulse Wave Velocity, PWV; Ankle-Brachial Index; ABI). Results showed that cardiac functional parameters (e.

DFT-Guided Design of Dual Dopants in Anatase TiO for Boosted Sodium Storage.

Anatase titanium dioxide (TiO) has drawn great attention as an anode material in sodium ion batteries (SIBs), but it suffers from the sluggish diffusion kinetics of Na within TiO and inferior electronic conductivity. Herein, under the guidance of density functional theory (DFT), we propose a nitrogen and selenium dual-doped TiO system as an advanced SIB anode. Both DFT and experimental investigations reveal the cooperative effect of dopants in boosting the electrochemical performance of TiO, finding the optimal content ratio (N/Se at 1:3) for overall improved SIB performances.

Short-term efficacy and safety of endoscopic injection of low dose of sclerotherapy and cyanoacrylate injection for type GOV1 gastric varices combined with endoscopic variceal ligation for esophageal varices.

Nanocarrier mediated delivery of insecticides into tarsi enhances stink bug mortality.

Current delivery practices for insecticide active ingredients are inefficient with only a fraction reaching their intended target. Herein, we developed carbon dot based nanocarriers with molecular baskets (γ-cyclodextrin) that enhance the delivery of active ingredients into insects (southern green stink bugs, Nezara viridula L.) via their tarsal pores.

Overexpression of SlATG8f gene enhanced autophagy and pollen protection in tomato under heat stress.

Autophagy is a mechanism for the degradation of cellular components in eukaryotes and plays a critical role in plant responses to abiotic stress. As a core member of the autophagy process, ATG8's role in how plants respond to heat stress remains unclear. To investigate the response of the tomato autophagy core member ATG8f to heat stress, we studied the key gene ATG8f and generated tomato lines overexpressing SlATG8f using the recombinant expression vector pBWA(V)HS.
