Hydrogen bonding-mediated phase-transition gelatin-based bioadhesives to regulate immune microenvironment for diabetic wound healing.

Gelatin-based biomaterials have emerged as promising candidates for bioadhesives due to their biodegradability and biocompatibility. However, they often face limitations due to the uncontrollable phase transition of gelatin, which is dominated by hydrogen bonds between peptide chains. Here, we developed controllable phase transition gelatin-based (CPTG) bioadhesives by regulating the dynamic balance of hydrogen bonds between the peptide chains using 2-hydroxyethylurea (HU) and punicalagin (PA).

Changes in methanogenic performance and microbial community during gradual transition from co-digestion with food waste to mono-digestion of rice straw.

This study investigated the performance and phase-specific characteristics of mesophilic co-digestion of food waste (FW) with rice straw (RS) at different RS proportions (40 %, 60 %, and 80 %), as well as mono-digestion of RS. The system achieved optimal performance at 40 % RS content, with a methane yield of 383.8 mL/g-VS and cellulose removal efficiency exceeding 75 %.

Non-Pharmacological Interventions Targeting Sense of Coherence Among Older Adults and Adults With Chronic Conditions: A Meta-Analysis With Trial Sequential Analysis.

Background: Sense of coherence (SoC) is a core concept of 'salutogenesis' in positive psychology, correlated with emotional distress and disease development in adults with chronic disease and older adults. A diversity of non-pharmacological interventions (NPIs) has been developed to enhance SoC, but research findings are conflicting and the adequacy of sample sizes is uncertainty.

Objective: This paper aimed to explore appropriate interventions, evaluate the effectiveness of these SoC interventions and verify the statistical robustness and reliability of pooled results.

Transcriptome comparison revealed the difference in subcutaneous fat metabolism of Qinghai yak under different feeding conditions.

In order to explore the differences in subcutaneous fat metabolism and pathway information in yaks under different feeding conditions, this experiment used Illumina high-throughput sequencing technology to sequence the transcriptome of subcutaneous fat tissues of yaks under different feeding conditions and analyzed them bioinformatically. 9 naturally grazed yaks at 18 months of age were randomly divided into 3 groups, one group (G18_SF) was slaughtered, one group (G24_SF) continued to graze until 24 months of age was slaughtered, and one group (F24_SF) was housed until 24 months of age was slaughtered, and subcutaneous fat tissue was collected from the back of the yaks. A total of 15,261 expressed genes were identified in the nine samples, with 13,959 coexpressed genes and 533 differential expressed genes (DEGs), G18_SF vs F24_SF 133 DEGs, G18_SF vs G24_SF 469 DEGs, F24_SF vs G24_SF 5 DEGs.

A gelatin/acrylamide-based hydrogel for smart drug release monitoring and radiation-induced wound repair in breast cancer.

Radiotherapy is a common local treatment for breast cancer, and while it is effective in targeting tumor cells, it inevitably causes significant side effects. These include excessive production of reactive oxygen species (ROS), repeated inflammatory, and severe skin ulceration, all of which can hinder the wound healing process. As a result, there is a pressing need for multifunctional medical dressings that can support wound repair following radiotherapy.

Selective Plasma Treatment Endowing Low-Friction and Wear-Resistant Surface of Polycrystalline Diamond against Copper.

Despite its unrivaled hardness, polycrystalline diamond can be severely worn under the interaction with softer copper during the ultrafine copper wire drawing process. The influence of the polycrystalline diamond surface state on its friction behavior is investigated in this work, and argon, oxygen, and hydrogen plasma treatments are adopted to regulate the surface state of diamond. When sliding against copper, the original diamond plate exhibits a coefficient of friction (COF) exceeding 0.

HIF-1α knockdown suppresses breast cancer metastasis via epithelial mesenchymal transition Abrogation.

Lung metastasis, a leading cause of breast cancer mortality, lacks effective therapeutic options. Hypoxia-inducible factor 1-alpha (HIF-1α) plays important roles in breast cancer progression, but its direct impact on lung metastasis remains unclear. Herein, in this study, we investigated the role of HIF-1α in breast cancer lung metastasis and the potential of targeting it for therapeutic benefit.

Biokinetic and microbial insights into regulatory mechanisms of long-chain fatty acid degradation during food waste-lipid co-digestion within anaerobic membrane bioreactor.

This study investigated the effects of varying lipid ratios on the anaerobic co-digestion of high-lipid food waste (FW) in a mesophilic anaerobic membrane bioreactor (AnMBR). At a lipid concentration of 5 %, optimal biogas production (3.84 L/L/d) and lipid removal efficiency (78 %) were achieved; however, increasing lipid concentrations resulted in significant accumulations of long-chain fatty acids (LCFAs) and volatile fatty acids (VFAs).

Room-temperature low-threshold avalanche effect in stepwise van-der-Waals homojunction photodiodes.

Avalanche or carrier-multiplication effect, based on impact ionization processes in semiconductors, has a great potential for enhancing the performance of photodetector and solar cells. However, in practical applications, it suffers from high threshold energy, reducing the advantages of carrier multiplication. Here, we report on a low-threshold avalanche effect in a stepwise WSe structure, in which the combination of weak electron-phonon scattering and high electric fields leads to a low-loss carrier acceleration and multiplication.

Enantioselective Synthesis of the 1,3-Dienyl-5-Alkyl-6-Oxy Motif: Method Development and Total Synthesis.

The 1,3-dienyl-5-alkyl-6-oxy motif is widely found in various types of bioactive natural products. However, present synthesis is mainly non-asymmetric which relied upon different olefination or transition metal-catalyzed cross-coupling reactions using enantioenriched precursors. Herein, based upon a newly developed enantioselective α-alkylation of conjugated polyenoic acids, a variety of 1,3-dienyl-5-alkyl-6-oxy motif (with E-configured internal olefin) was generated as the corresponding α-adducts in a highly enantioselective and diastereoselective manner.

Prostate transmembrane androgen inducible protein 1 : regulation and clinical implications.

Prostate transmembrane androgen inducible protein 1 (PMEPA1) can promote or inhibit prostate cancer cell growth based on the cancer cell response to the androgen receptor (AR). Further, it can be upregulated by transforming growth factor (TGF), which downregulates transforming growth factor-β (TGF-β) signaling by interfering with R-Smad phosphorylation to facilitate TGF-β receptor degradation. Studies have indicated the increased expression of PMEPA1 in some solid tumors and its functioning as a regulator of multiple signaling pathways.

Knockdown of LOX-1 ameliorates bone quality and generation of type H blood vessels in diabetic mice.

Our previous studies have shown that lectin-like oxidized low-density lipoprotein receptor 1 (LOX-1) is expressed in liver sinusoidal endothelial cells, and oxidized low-density lipoprotein induces liver sinusoidal dysfunction and defenestration through the LOX-1/ROS/NF-kB pathway, revealing that LOX-1 can mediate liver sinusoidal barrier function, involved in the regulation of non-alcoholic fatty liver disease. Here, we investigated whether, in the context of bone metabolic diseases, LOX-1 could affect bone quality and type H blood vessels in diabetic mice. We used db/db mice as model and found that LOX-1 knockdown can ameliorate bone quality and type H blood vessel generation in db/db mice.
