Rapidly self-crosslinking sodium alginate hydrogel for infected wounds.

The risks associated with wound infections are significant, making a snug-fitting hydrogel dressing an optimal choice for wound management. For it, we employed the self-cross-linking method of oxidized sodium alginate (SCSA), incorporating clarithromycin (Cla) and basic fibroblast growth factor (bFGF) to formulate a rapidly forming, bacteriostatic, and wound-healing hydrogel (SCSA@C/b). Bacteriostatic and cytocompatibility assays demonstrated that SCSA@C/b exhibits exceptional antibacterial activity alongside strong biocompatibility.

Copper(II)-Catalyzed Enantioselective Addition of Aryl Amines to Isatin-Derived -Boc-Ketimines for the Synthesis of Acyclic ,'-Ketals.

Here, we demonstrated a copper(II)-catalyzed enantioselective addition of aryl amines to isatin-derived -Boc-ketimines using chiral O-N-N tridentate ligands derived from BINOL and proline. Generally, the chiral acyclic ,'-ketals were obtained in high yields (up to 98%) and excellent ee values (up to 98%). Various aryl amines could be tolerated and a gram-scale reaction was also possible.

TCBGY net for enhanced wear particle detection in ferrography using self attention and multi scale fusion.

The intelligent identification of wear particles in ferrography is a critical bottleneck that hampers the development and widespread adoption of ferrography technology. To address challenges such as false detection, missed detection of small wear particles, difficulty in distinguishing overlapping and similar abrasions, and handling complex image backgrounds, this paper proposes an algorithm called TCBGY-Net for detecting wear particles in ferrography images. The proposed TCBGY-Net uses YOLOv5s as the backbone network, which is enhanced with several advanced modules to improve detection performance.

Evidence of an emerging triple-reassortant H3N3 avian influenza virus in China.

A read-through circular RNA RCRIN inhibits metabolic dysfunction-associated steatotic liver disease.

Background & Aims: The molecular mechanism underlying metabolic dysfunction-associated steatotic liver disease (MASLD) is elusive and whether non-coding RNAs can serve as biomarkers and therapeutic targets of MASLD is less defined.

Methods: Exon capture RNA sequencing analysis was used to identify read-through circRNAs (rt-circRNAs) in livers from three MASLD patients and three patients without MASLD. Hepatocyte-specific deletion or overexpression of rt-circRNA RCRIN were utilized to study MASLD pathogenesis.

Exploring strategies for kitchen waste treatment and remediation from the perspectives of microbial ecology and genomics.

Nowadays, the rapid growth of population has led to a substantial increase in kitchen waste and wasted sludge. Kitchen waste is rich in organic matter, including lignocellulose. Synergistic treatment involving kitchen waste and wasted sludge can enhance treatment process.

Meta-analysis of the effect of sophora flavescens on tumor metastasis-induced bone neuropathic pain.

Background: Tumor metastasis to bone is a critical and painful stage in cancer progression, significantly affecting patients' quality of life. Traditional treatments for bone neuropathic pain often exhibit limited efficacy and undesirable side effects. Sophora flavescens, an herb used in traditional Chinese medicine, has shown potential analgesic and anti-cancer properties, but the existing evidence is fragmented and inconsistent.

Oblique Lumbar Interbody Fusion Combined With Anterolateral Fixation and Cement Augmentation for the Treatment of Degenerative Lumbar Diseases in the Elderly Population: A Retrospective Study.

Objectives: Cage subsidence is a common complication of oblique lumbar interbody fusion (OLIF), particularly in elderly patients with osteoporosis or osteopenia. While bilateral pedicle screw fixation (BPS) is effective in reducing subsidence, it is associated with longer operative times, increased blood loss, and greater tissue trauma. In contrast, anterolateral fixation (AF) is less invasive but linked to higher subsidence rates.

Objective: To analyze part of the mechanism of electroacupuncture on Sishencong (EX-HN1) for stroke-related sleep disorders (SSD) and post-stroke cognitive impairment (PSCI).

Methods: Using a randomized controlled trial (RCT) design, 72 patients were assigned to the electro-acupuncture (EA) group or the sham acupuncture (SA) group. A healthy control (HC) group was also included.

Doxorubicin- and Selenium-Incorporated Mesoporous Silica Nanoparticles as a Combination Therapy for Osteosarcoma.

Doxorubicin (Dox) is a promising anticancer chemotherapeutic, which has been widely investigated in osteosarcoma (OS) treatment. However, there are several disadvantages regarding its clinical use. Specifically, Dox has low specificity toward cancer cells, which can lead to serious side effects.

A Microporous Hydrogen-Bonded Organic Framework with Open Pyrene Sites Isolated by Hydrogen-Bonded Helical Chains for Efficient Separation of Xenon and Krypton.

Achieving efficient xenon/krypton (Xe/Kr) separation in emerging hydrogen-bonded organic frameworks (HOFs) is highly challenging because of the lack of gas-binding sites on their pore surfaces. Herein, we report the first microporous HOF (HOF-FJU-168) based on hydrogen-bonded helical chains, which prevent self-aggregation of the pyrene core, thereby preserving open pyrene sites on the pore surfaces. Its activated form, HOF-FJU-168a is capable of separating Xe/Kr under ambient conditions while achieving an excellent balance between adsorption capacity and selectivity.

Refining antipsychotic treatment strategies in schizophrenia: discovery of genetic biomarkers for enhanced drug response prediction.

Schizophrenia (SCZ) is a severe mental disorder affecting around 1% of individuals worldwide. The variability in response to antipsychotic drugs (APDs) among SCZ patients presents a significant challenge for clinicians in determining the most effective medication. In this study, we investigated the biological markers and established a predictive model for APD response based on a large-scale genome-wide association study using 3269 Chinese schizophrenia patients.

Inhibition of breast cancer growth with AN-329, a novel Hsp110 inhibitor, by inactivating p-STAT3/c-Myc axis.

Breast cancer, a leading cause of cancer-related mortality in women, is characterized by its propensity for metastasis. Heat shock protein 110 (Hsp110), a molecular chaperone encoded by the HSPH1 gene, has been implicated in cancer progression, including breast cancer, where it is upregulated and associated with worse outcomes. However, the role of Hsp110 in breast cancer pathogenesis and its potential as a therapeutic target have not been thoroughly investigated.

Optimizing Propylene/Propane Sieving Separation through Gate-Pressure Control within a Flexible Organic Framework.

The separation of propylene (CH) and propane (CH) is of great significance in the chemical industry, which poses a challenge due to their almost identical kinetic diameters and similar physical properties. In this work, we synthesized an ultramicroporous flexible hydrogen-bonded organic framework (named HOF-FJU-106) by using molecule 2,3,6,7-tetra (4-cyanophenyl) tetrathiafulvalene (TTF-4CN). The formation of the dimer causes the TTF-4CN molecular to bend and weaken π-stacked interactions, coupled with the flexibility of C≡N H-C hydrogen bonds, which leads to reversible conversion between open and closed frameworks through the mutual slip of adjacent layers/columns under activation and stimulation of gas molecules.

Reversible-gel-assisted, ambient-pressure-dried, multifunctional, flame-retardant biomass aerogels with smart high-strength-elasticity transformation.

Bio-based aerogels, which are poised as compelling thermal insulators, demand intricate synthesis procedures and have limited durability under harsh conditions.
