Glycopeptide microneedles triggering the ECM process to promote fibroblast viability for anti-aging treatments.

Skin anti-aging remains challenging due to the cumulative detrimental effects within the intricate microenvironment. Here, we present glycopeptide hydrogel (γ-PGA/HA) microneedle patches composed of poly (γ-glutamic acid) and hyaluronic acid as a potential solution. These microneedles aim to effectively penetrate the skin barrier while remodeling extracellular matrix to regulate the skin microenvironment.

A N7-methylguanosine modified circular RNA, circIPP2A2, promotes malignant behaviors in hepatocellular carcinoma by serving as a scaffold in modulating the Hornerin/PI3K/AKT/GSK3β axis.

Despite the advancements in treatment strategies, the long-term survival of hepatocellular carcinoma (HCC) is still pessimistic. Therefore, understanding the mechanisms of hepatocellular carcinoma may offer substantial benefits for patients. Our previous research has revealed that Hornerin promoted HCC progression by regulating the AKT signaling pathway.

An engineered dual-functional L-DOPA decarboxylase enables a minimized hydroxytyrosol cascade.

Hydroxytyrosol has been proven beneficial to human health. However, the process involving the conversion of L-DOPA to 3,4-dihydroxyphenylacetaldehyde (3,4-DHPAA) in hydroxytyrosol biosynthesis typically required the simultaneous use of decarboxylase and oxidative deaminase. In addition, phenylacetaldehyde reductase from Solanum lycopersicum (SlPAR) in hydroxytyrosol biosynthesis exhibits poor thermal stability.

Synthesis of novel deep eutectic solvent-modified nano cellulosic gel formulation-based strain sensor for human motion monitoring.

Using deep eutectic solvents (DES) to pretreat wheat straw (WS) and extract lignin-containing nanocellulose (LCNC). Acrylic acid/choline chloride (AA/ChCl) polymerizable deep eutectic solvents (PDES) were used as the primary polymerization network, combined with polyvinyl alcohol (PVA). Lignocellulose nanocrystals (LCNC) oxidized by sodium periodate were prepared as dialdehyde-based nanocellulose (DCNC) to serve as the crosslinking agent.

The causal effect of serum amino acids on the risk of prostate cancer: a two-sample mendelian randomization study.

Prostate cancer (PCa) is the second most common malignancy affecting men globally. Recent advances in metabolomics have highlighted significant alterations in specific amino acid (AA) metabolism linked to PCa, indicating their potential utility in diagnosis and therapy. However, no direct causal association between serum AA levels and PCa risk has been established.

Carboxymethyl chitosan: Synthesis, functional properties, and applications in sustainable food packaging material.

Global environmental concerns about non-degradable packaging materials are increasing. Carboxymethyl chitosan (CMCS), a polysaccharide widely used in the food industry, has gained attention in the field of food packaging. Due to its biodegradability, film-forming ability, and biocompatibility, CMCS has emerged as a sustainable option for degradable and functional food packaging materials, offering solutions to plastic pollution and food waste issues.

Role of the mA demethylase ALKBH5 in gastrointestinal tract cancer (Review).

N6‑methyladenosine (mA) is one of the most universal, abundant and conserved types of internal post‑transcriptional modifications in eukaryotic RNA, and is involved in nuclear RNA export, RNA splicing, mRNA stability, gene expression, microRNA biogenesis and long non‑coding RNA metabolism. AlkB homologue 5 (ALKBH5) acts as a m6A demethylase to regulate a wide variety of biological processes closely associated with tumour progression, tumour metastasis, tumour immunity and tumour drug resistance. ALKBH5 serves a crucial role in human digestive system tumours, mainly through post‑transcriptional regulation of mA modification.

The neurotoxicity of acrylamide in ultra-processed foods: interventions of polysaccharides through the microbiota-gut-brain axis.

Ultra-processed foods (UPFs) have become popular in recent years, however, the detrimental effects of their excessive consumption have also become evident. Acrylamide (AA), a processing hazard present in UPFs, can further aggravate the harmful effects of UPFs. AA can cause significant damage to both the intestinal barrier and gut microbiota, thereby affecting the nervous system through the microbiota-gut-brain (MGB) axis.

Thermo-responsive hydrogel loading hypericin induces pro-inflammatory response against Trichinella spiralis infection via toll-like receptor 3 activation.

Background: Trichinella spiralis can cause animal and human trichinellosis, which is fatal for human beings. Study demonstrated that toll-like receptor 3 (TLR3) agonist was effective in reducing trichinella infections. Hypericin (Hyp) has great potential in activating TLR3 and may be a favorable choice for immunotherapy of trichinellosis.

Complete genome sequence of a new poacevirus infecting wild oat (Avena fatua L.) in France.

Using a high-throughput sequencing (HTS) approach, we report the discovery of a new poacevirus (family Potyviridae) in symptomatic wild oat (Avena fatua L.) plants collected near Bordeaux, France, in June 2023. A nearly complete genome sequence of 10,292 nucleotides (nt) was obtained.

Polymerization-Achieved Cyclodextrin Slide-Ring Supramolecular Hydrogel Self-Generating Flexible Electronic Device.

Supramolecular flexible electronic devices are one of the research hotspots due to their application in the fields of chemistry, biology, and materials. Herein, we reported a slide-ring supramolecular flexible electronic device, which is constructed by acrylamide (AAm), acrylic acid (AA), carboxymethyl-α-cyclodextrin (CM-α-CD), PEG diacrylate (PEGDA), and calcium chloride via the photoinitiated polymerization, displaying not only the mechanical force-responded self-generation but also the human-computer information transfer. As compared with the polymer hydrogel, the addition of α-CD polypseudorotaxane to the hydrogel has notably enhanced both the tensile length and the tensile toughness, making it more suitable for flexible electronic device applications.

Nicotinamide Riboside Ameliorates Fructose-Induced Lipid Metabolism Disorders in Mice by Activating Browning of WAT, and May Be Also Related to the Regulation of Gut Microbiota.

Objectives: This study aims to observe the preventive effect of nicotinamide riboside (NR) on fructose-induced lipid metabolism disorders and explore its mechanism.

Methods: Male C57BL/6J mice were fed a 20% fructose solution and given 400 mg/kg NR daily by gavage for 10 weeks.

Results: The results indicated that NR supplementation significantly reduced the body weight, liver weight, white adipose tissue (WAT) weight, serum, and hepatic lipid levels.

SLAM Algorithm for Mobile Robots Based on Improved LVI-SAM in Complex Environments.

The foundation of robot autonomous movement is to quickly grasp the position and surroundings of the robot, which SLAM technology provides important support for. Due to the complex and dynamic environments, single-sensor SLAM methods often have the problem of degeneracy. In this paper, a multi-sensor fusion SLAM method based on the LVI-SAM framework was proposed.

The primary studies of epigallocatechin-3-gallate in improving brain injury induced by chronic high-altitude natural environment in rats by 7.0T high-field MR imaging.

Background: Epigallocatechin-3-gallate (EGCG) is one of the most abundant and important bioactive polyphenolic compounds in green tea. However, despite its potent antioxidant effects, its neuroprotective effects on chronic high altitude (HA)-induced nerve damage have not been reported. The purpose of this study is to use quantitative susceptibility mapping (QSM) with pathology to dynamically evaluate the status of brain damage and the effect of EGCG.

MEHP induced mitochondrial damage by promoting ROS production in CIK cells, leading to apoptosis, autophagy, cell cycle arrest.

Although Mono (2-ethylhexyl) phthalate (MEHP) is a metabolite of Di (2-ethylhexyl) phthalate (DEHP), it has been confirmed to exhibit stronger biological toxicity than DEHP. Mitochondrial dynamic homeostasis and normal mitochondrial function regulate numerous physiological and pathological processes. However, it remains unclear whether MEHP triggers apoptosis, autophagy, and cell cycle arrest in grass carp kidney (CIK) cells by causing mitochondrial damage.
