Background: Autophagy and immunity play important regulatory roles in lung developmental disorders. However, there is currently a lack of bioinformatics analysis on autophagy-related genes (ARGs) and immune infiltration in bronchopulmonary dysplasia (BPD). We aim to screen and validate the signature genes of BPD by bioinformatics and in vivo experiment.

Spontaneous Formation of Single-Crystalline Spherulites in a Chiral 2D Hybrid Perovskite.

In two-dimensional (2D) chiral metal-halide perovskites (MHPs), chiral organic spacers induce structural chirality and chiroptical properties in the metal-halide sublattice. This structural chirality enables reversible crystalline-glass phase transitions in (-NEA)PbBr, a prototypical chiral 2D MHP where NEA represents 1-(1-naphthyl)ethylammonium. Here, we investigate two distinct spherulite states of (-NEA)PbBr, exhibiting either radial-like or stripe-like banded patterns depending on the annealing conditions of the amorphous film.

Effective Hydrogel Vascular Patch Dual-Loaded with Cycloastragenol Nanostructured Lipid Carriers and Doxycycline for Repairing Extravascular Injury in Abdominal Aortic Aneurysm.

Endovascular aneurysm repair (EVAR) plays a crucial role in the treatment of abdominal aortic aneurysm (AAA) in the clinic, but the aneurysm remains in the patient's body after surgery, continuing to pose a risk of progression. Cycloastragenol (CAG) is proven to be an effective anti-AAA drug, and its vascular protective effects can be further improved when the hydrophobic CAG is encapsulated into nano-sized formulations to enhance its bioavailability. In this context, this study developed an extravascular patch hydrogel loaded with CAG nanostructured lipid carriers and a hydrophilic drug of doxycycline hydrochloride (DOX).

As a follow-up study, we here made advances by pinpointing a Lactobacillus murinus (L.m.

Integrated Biochemical and Computational Methods for Deciphering RNA-Processing Codes.

RNA processing involves steps such as capping, splicing, polyadenylation, modification, and nuclear export. These steps are essential for transforming genetic information in DNA into proteins and contribute to RNA diversity and complexity. Many biochemical methods have been developed to profile and quantify RNAs, as well as to identify the interactions between RNAs and RNA-binding proteins (RBPs), especially when coupled with high-throughput sequencing technologies.

Integrated omics profiling reveals systemic dysregulation and potential biomarkers in the blood of patients with neuromyelitis optica spectrum disorders.

Background: Neuromyelitis optica spectrum disorders (NMOSD) are autoimmune conditions that affect the central nervous system. The contribution of peripheral abnormalities to the disease's pathogenesis is not well understood.

Methods: To investigate this, we employed a multi-omics approach analyzing blood samples from 52 NMOSD patients and 46 healthy controls (HC).

A machine learning based approach to standardizing tooth color and shade recommendations.

Statement Of Problem: Achieving the precise reproduction of tooth color is pivotal in esthetic restorations. However, existing visual and instrumental shade matching methods, each with inherent limitations, have often resulted in inconsistent color communication and subsequently suboptimal esthetic results in clinical practice.

Purpose: The purpose of this in vitro study was to evaluate a 2-tier color correction strategy to accurately acquire standardized tooth color and to provide shade recommendations for esthetic restorations.

Pressure-constrained sonication activation of flexible printed metal circuit.

Metal micro/nanoparticle ink-based printed circuits have shown promise for promoting the scalable application of flexible electronics due to enabling superhigh metallic conductivity with cost-effective mass production. However, it is challenging to activate printed metal-particle patterns to approach the intrinsic conductivity without damaging the flexible substrate, especially for high melting-point metals. Here, we report a pressure-constrained sonication activation (PCSA) method of the printed flexible circuits for more than dozens of metal (covering melting points from room temperature to 3422 °C) and even nonmetallic inks, which is integrated with the large-scale roll-to-roll process.

Molecular serotyping of diarrheagenic with a MeltArray assay reveals distinct correlation between serotype and pathotype.

Diarrheagenic serotypes are associated with various clinical syndromes, yet the precise correlation between serotype and pathotype remains unclear. A major barrier to such studies is the reliance on antisera-based serotyping, which is culture-dependent, low-throughput, and cost-ineffective. We have established a highly multiplex PCR-based serotyping assay, termed the MeltArray serotyping () assay, capable of identifying 163 O-antigen-encoding genes and 53 H-antigen-encoding genes of .

Yanghe Decoction promotes ferroptosis through PPARγ-dependent autophagy to inhibit the malignant progression of triple-negative breast cancer.

Triple-negative breast cancer (TNBC) is a heterogeneous subtype of breast cancer that displays highly aggressive with poor prognosis. Yanghe Decoction (YHD) has been used in the treatment of breast cancer for many years. We aimed to explore the effects of YHD on the malignant phenotypes of MDA-MB-231 cells and the potential mechanism related to PPARγ, autophagy and ferroptosis.

Research progress in the mechanisms and functions of specialized pro-resolving mediators in neurological diseases.

The nervous system interacts with the immune system through a variety of cellular regulators, signaling pathways, and molecular mechanisms. Disruptions in these interactions lead to the development of multiple neurological diseases. Recent studies have identified that specialized pro-resolving mediators (SPMs) play a regulatory role in the neuroimmune system.

Protein Complex Heterogeneity and Topology Revealed by Electron Capture Charge Reduction and Surface Induced Dissociation.

We illustrate the utility of native mass spectrometry (nMS) combined with a fast, tunable gas-phase charge reduction, electron capture charge reduction (ECCR), for the characterization of protein complex topology and glycoprotein heterogeneity. ECCR efficiently reduces the charge states of tetradecameric GroEL, illustrating Orbitrap / measurements to greater than 100,000 /. For pentameric C-reactive protein and tetradecameric GroEL, our novel device combining ECCR with surface induced dissociation (SID) reduces the charge states and yields more topologically informative fragmentation.

Bowel function, quality of life, and mental health of patients with high-grade intraepithelial neoplasia or T1 colorectal cancer after organ-preserving versus organ-resection surgeries: a cross-sectional study at a Chinese tertiary care center.

Background: This study aimed to determine the postoperative intestinal functioning, quality of life (QoL), and psychological well-being of patients treated either with organ-preserving surgery (OPS) or organ-resection surgery (ORS) for high-grade intraepithelial neoplasia (HIN) or T1 colorectal cancer (CRC).

Methods: This cross-sectional study was conducted at a single tertiary care center. In total, 175 eligible individuals with T1 CRC or HIN were divided into the OPS (n = 103) or ORS (n = 72) group based on whether the relevant segment of the intestine was preserved or resected.

Nuclear retention coupled with sequential polyadenylation dictates post-transcriptional mA modification in the nucleus.

N-methyladenosine (mA) modification is deemed to be co-transcriptionally installed on pre-mRNAs, thereby influencing various downstream RNA metabolism events. However, the causal relationship between mA modification and RNA processing is often unclear, resulting in premature or even misleading generalizations on the function of mA modification. Here, we develop 4sU-coupled mA-level and isoform-characterization sequencing (4sU-mA-LAIC-seq) and 4sU-GLORI to quantify the mA levels for both newly synthesized and steady-state RNAs at transcript and single-base-resolution levels, respectively, which enable dissecting the relationship between mA modification and alternative RNA polyadenylation.
