Nanogenerators for gas sensing applications.

Gas sensors are now widely employed in many industries due to the rapid speed of industrialization and the growth of the Internet of Things. However, the wearability and mobility of traditional gas sensors are limited by their high reliance on external power sources. Nanogenerators (NGs) can compensate for their power source limitations when paired with gas sensors by transforming the environment's widely dispersed low-frequency energy into electrical energy, allowing for self-powered gas detection.

Downregulation of RSAD2 ameliorates keratinocyte hyperproliferation and skin inflammation in psoriasis via the TAK1/NF-κB axis.

Immune cell infiltration and keratinocyte (KC) hyperproliferation are characteristics of psoriasis. Radical S-adenosyl methionine domain-containing 2 (RSAD2) plays an integral role in the innate immune response and is associated with various immune-related diseases. However, RSAD2's expression and role in modulating immune responses in psoriasis remain unexplored.

Oral resists the acidic pH of the stomach due to membrane erucic acid synthesized via enoyl-CoA hydratase-related protein FnFabM.

Methods: To investigate the mechanisms of acid resistance in oral bacteria, an in vitro gastrointestinal tract Dynamic pH Model was established.

Integrative multi-omics analysis reveals liver-gut axis adaptation in high-altitude goats.

The liver-gut axis is an important regulatory axis for the host's metabolic functions. The study of liver gene expression, changes in metabolic products and the regulation of gut microbial communities in plateau animals under harsh environments can reveal the mechanisms by which Tibetan goats adapt to the plateau environment. This study employs transcriptome, metabolome and metagenomic analyses to reveal the differences in genes, metabolism, and gut microbiota between Jianzhou big-eared goats (JBG) and Xizang cashmere goats (TCG), which is of significant importance for improving survival models of high-altitude ruminants.

Discovery of a common light chain bispecific antibody targeting PD-1 and PD-L1 by Hybridoma-to-Phage-to-Yeast (H2PtY) platform.

Background: Therapeutic antibody drugs targeting the PD-1 pathway are generally characterized by relatively low response rates and susceptibility to drug resistance during clinical application. Therefore, there is an urgent need for alternative therapeutic strategies to increase the immune response rate. Bispecific antibodies co-targeting PD-1 and PD-L1 may have greater potential to improve the efficacy of the immune checkpoint pathway.

A Randomized, Comparative Trial of a Potassium-Competitive Acid Blocker (X842) and Lansoprazole for the Treatment of Patients with Erosive Esophagitis.

Introduction: X842 is a new type of gastric acid-suppressing agent with a rapid onset of action and a long duration of effect. We aim to investigate the efficacy and safety of different doses of X842 versus lansoprazole in the treatment of patients with erosive esophagitis (EE).

Methods: This phase 2 study included 90 patients with EE (Los Angeles grades A-D) who were randomized (1:1:1) to receive oral low-dose X842 (50 mg/day, n=31), high-dose X842 (100 mg/day, n=31), or lansoprazole (30 mg/day, n=30) for 4 weeks.

Structural insights into RNA cleavage by PIWI Argonaute.

Argonaute proteins are categorized into AGO and PIWI clades. Across most animal species, AGO-clade proteins are widely expressed in various cell types, and regulate normal gene expression. By contrast, PIWI-clade proteins predominantly function during gametogenesis to suppress transposons and ensure fertility.

Intermediate-dose immune tolerance induction outperforms with faster success, less bleeding, and no added cost in comparison with low dose: a multicenter randomized clinical trial.

Background: Low-dose (LD) or intermediate-dose (MD) immune tolerance induction (ITI) is effective in children with severe hemophilia A (SHA) with high-titer inhibitors (HTIs) and is attractive in countries with economic constraints. However, high-quality evidence of their use is lacking.

Objectives: This was a multicenter randomized clinical trial comparing the efficacy, safety, and medication cost between LD-ITI and MD-ITI for SHA-HTI children.

Porcine pericardial decellularized matrix bilayer patch containing adipose stem cell-derived exosomes for the treatment of diabetic wounds.

Chronic hard-to-heal wounds pose a significant threat to patients' health and quality of life, and their clinical management remains a challenge. Adipose-derived stem cell exosomes (ADSC-exos) have shown promising results in promoting diabetic wound healing. However, effectively enhancing the retention of exosomes in wounds for treatment remains a key issue that needs to be addressed.

Generation of a KDM5D knockout human embryonic stem cell line with CRISPR/Cas9 technology.

KDM5D is a gene implicated in spermatogenic failure and sex-related differences in colon cancer progression, though its role in spermatogenesis remains unclear. We successfully generated a KDM5D knockout human embryonic stem cells using CRISPR/Cas9 technology. This knockout cell line provides a valuable model for studying KDM5D's function in spermatogenesis and its influence on sex differences in various diseases.

Small-molecule organic ice microfibers.

Small organic molecules are essential building blocks of our universe, from cosmic dust to planetary surfaces to life. Compared to their well-known gaseous and liquid forms that have been extensively studied, small organic molecules in the form of ice at low temperatures receive much less attention. Here, we show that supercooled small-molecule droplets can be drawn into highly uniform amorphous ice microfibers with lengths up to 5 cm and diameters down to 200 nm.

A dual-drive strategy for enhanced protein crystallization with sodium alginate/hyaluronic acid film: Protein adsorption and supersaturation regulation.

Protein crystallization is essential for determining the three-dimensional structures of biomacromolecules and advancing biopharmaceutical development, yet it remains a major challenge in structural biology due to common issues like slow nucleation rates and inconsistent crystal quality. Herein, a dual-drive crystallization (DDC) strategy, relying on a composite film of sodium alginate (SA) and hyaluronic acid (HA), is reported to synergistically regulate both protein adsorption and solution supersaturation. Driven by the electrostatic interactions of SA and the water absorption properties of HA, the SA/HA film achieves enhanced crystallization efficiency and controlled crystal quality mainly.

Generation of a USP9Y knockout human embryonic stem cell line with CRISPR-Cas9 technology.

Human embryonic stem cell (hESC) lines are vital tools for studying gene function, disease modeling, and therapy. We generated a USP9Y knockout hESC line using CRISPR-Cas9 in the male-derived H1 line. Targeted deletion of the USP9Y gene was confirmed via PCR and sequencing.

Polo-like kinase 4 accelerates glioma malignant progression and vasculogenic mimicry by phosphorylating EphA2.

Vasculogenic mimicry (VM), which involved the formation of vascular-like structures by highly invasive tumor cells, had been identified as one of the mechanisms contributing to resistance against anti-angiogenic therapy in patients with glioblastoma (GBM). Therefore, inhibition of VM formation may serve as an effective therapeutic strategy against angiogenesis resistance. Polo-like kinase 4 (PLK4), a protein kinase, had been linked to the progression of glioblastoma and was associated with an unfavorable prognosis.

Discovery of a novel Fam20C inhibitor for treatment of triple-negative breast cancer.

Sequence similarity 20 family member C (Fam20C), a Golgi casein kinase, has a gradually elucidated mechanism in triple-negative breast cancer (TNBC) and is considered a possible target for therapeutic intervention. In this study, we combined virtual screening and chemical synthesis methods to obtain a new small-molecule Fam20C inhibitor, compound 5k, which possesses desirable kinase inhibitory activity against Fam20C and significant anti-proliferative activity against MDA-MB-231 and BT-549 cells. Subsequently, cellular thermal shift assay (CETSA), molecular docking, and molecular dynamics (MD) simulations revealed that compound 5k binds to Fam20C.
