Ultrasound-Assisted H Transmitter Enables Hydrogen-Gene Therapy to Prevent Anesthesia/Surgery-Induced Cognitive Impairment.

Postoperative cognitive dysfunction (POCD) frequently occurs after surgery, resulting in extended hospitalizations, higher healthcare expenses, and potential long-term cognitive impairment. Despite its significant impact, effective preventive and therapeutic strategies for POCD are still lacking. Neuroinflammation plays a crucial role in the pathogenesis of POCD.

Transdermal microneedle-assisted ultrasound-enhanced CRISPRa system to enable sono-gene therapy for obesity.

Obesity, a surging global health challenge, necessitates effective, accessible and innovative therapeutic models. Here we develop a spatiotemporally controllable microneedle (MN) drug delivery platform for sono-gene therapy to fight obesity. The platform delivers the methoxy polyethylene glycol-polyethyleneimine (mPEG-PEI) modified metal-organic frameworks (MOFs) sonosensitizer and the clustered regularly interspaced short palindromic repeats-activating (CRISPRa)/CRISPRa-uncoupling protein 1 (UCP1) system intradermally to adipocytes.

Losartan-based nanocomposite hydrogel overcomes chemo-immunotherapy resistance by remodeling tumor mechanical microenvironment.

Preclinical studies demonstrating high cure rates with PD1/PD-L1 combinations have led to numerous clinical trials, but emerging results are disappointing. These combined immunotherapies are commonly employed for patients with refractory tumors following prior treatment with cytotoxic agents. Here, we uncovered that the post-chemotherapy tumor presents a unique mechanical microenvironment characterized by an altered extracellular matrix (ECM) elasticity and increased stiffness, which facilitate the development of aggressive tumor phenotypes and confer resistance to checkpoint blocking therapy.

Microbial corrosion of metallic biomaterials in the oral environment.

A wide variety of microorganisms have been closely linked to metal corrosion in the form of adherent surface biofilms. Biofilms allow the development and maintenance of locally corrosive environments and/or permit direct corrosion including pitting corrosion. The presence of numerous genetically distinct microorganisms in the oral environment poses a threat to the integrity and durability of the surface of metallic prostheses and implants used in routine dentistry.

Fagopyrum Dibotrys Rhizoma regulates pulmonary lipid metabolic homeostasis and the ERK-cPLA pathway to alleviate asthma in mice.

Background: Asthma is a complex disease with mechanisms involving multiple factors, and there is still a lack of highly effective and low-side-effect drugs. Traditional Chinese medicine Fagopyrum Dibotrys Rhizoma (FDR) has been applied for the treatment of acute and chronic bronchitis as well as bronchial asthma due to its favorable pharmacological activity. However, the exact mechanism of FDR remains unclear.

Corrigendum: Expression profiling of ALOG family genes during inflorescence development and abiotic stress responses in rice ().

[This corrects the article DOI: 10.3389/fgene.2024.

Expression profiling of ALOG family genes during inflorescence development and abiotic stress responses in rice ( L.).

The ALOG ( LSH1 and G1) family proteins, namely, DUF640 domain-containing proteins, have been reported to function as transcription factors in various plants. However, the understanding of the response and function of ALOG family genes during reproductive development and under abiotic stress is still largely limited. In this study, we comprehensively analyzed the structural characteristics of ALOG family proteins and their expression profiles during inflorescence development and under abiotic stress in rice.

Multiple-matrix metabolomics analysis for the distinct detection of colorectal cancer and adenoma.

Objectives: Although colorectal cancer (CRC) is the leading cause of cancer-related morbidity and mortality, current diagnostic tests for early-stage CRC and colorectal adenoma (CRA) are suboptimal. Therefore, there is an urgent need to explore less invasive screening procedures for CRC and CRA diagnosis.

Methods: Untargeted gas chromatography-mass spectrometry (GC-MS) metabolic profiling approach was applied to identify candidate metabolites.

Aldicarb disturbed bile acid, steroid hormone and oxylipin homeostasis in C57BL/6 J mice.

Mounting evidence has shown that the gut microbiota plays a key role in human health. The homeostasis of the gut microbiota could be affected by many factors, including environmental chemicals. Aldicarb is a carbamate insecticide used to control a variety of insects and nematode pests in agriculture.

Analysis of gut microbiota metabolites of platycodin D and activity verification.

As the main saponin component of Platycodon grandiflorum A.DC, Platycodin D has been reported to have an anti-obesity effect. Due to poor oral absorption, the intestinal microflora usually transforms saponins into potential bioactive substances.

Integration of semi-empirical MS/MS library with characteristic features for the annotation of novel amino acid-conjugated bile acids.

Recently, amino acids other than glycine and taurine were found to be conjugated with bile acids by the gut microbiome in mouse and human. As potential diagnostic markers for inflammatory bowel disease and farnesoid X receptor agonists, their physiological effects and mechanisms, however, remain to be elucidated. A tool for the rapid and comprehensive annotation of such new metabolites is required.

Optimization of bronchoalveolar lavage fluid volume for untargeted lipidomic method and application in influenza A virus infection.

Bronchoalveolar lavage (BAL) has been widely applied for the diagnosis of pulmonary diseases in clinical as it was recognized as a minimally invasive, well-tolerated and easily performed procedure. Lipid analysis of BAL fluid is a comprehensive strategy to observe lipid phenotypes, explore potential biomarkers, and elucidate the biological mechanisms of respiratory diseases. However, the highly diverse concentration of lipids in BAL fluid due to the deviation between the retrieved and injected aliquot volumes during lavage raised a challenge in obtaining high-quality lipidomic data.

Electroacupuncture intervention on stress-induced cardiac autonomic imbalance in rats involves corticotropin-releasing hormone system activity.

Autonomic imbalance is a core aspect of stress response that strongly correlates to cardiovascular diseases. Enhanced activity of the central corticotropin-releasing hormone (CRH) system may result in autonomic imbalance to cause cardiovascular responses in a stress state. Electroacupuncture at PC6 acupoints has been demonstrated to prevent and treat cardiovascular diseases.
