A two-in-one molybdenum disulfide-chitosan nanoparticles system for activating plant defense mechanisms and reactive oxygen species to treat Citrus Huanglongbing.

Citrus Huanglongbing (HLB) poses an enormous challenge to Citrus cultivation worldwide, necessitating groundbreaking interventions beyond conventional pharmaceutical methods. In this study, we propose molybdenum disulfide-chitosan nanoparticles (MoS-CS NPs) through electrostatic adsorption, preserving the plant-beneficial properties of molybdenum disulfide (MoS), while enhancing its antibacterial effectiveness through chitosan modification. MoS-CS NPs exhibited significant antibacterial efficacy against RM1021, and the closest relatives to Candidatus Liberibacter asiaticus (CLas), Erwinia carotovora, and Xanthomonas citri achieved survival rates of 7.

Mapping subcellular RNA localization with proximity labeling.

The subcellular localization of RNA is critical to a variety of physiological and pathological processes. Dissecting the spatiotemporal regulation of the transcriptome is key to understanding cell function and fate. However, it remains challenging to effectively enrich and catalogue RNAs from various subcellular structures using traditional approaches.

Genetically predicted fatty liver disease and risk of psychiatric disorders: A mendelian randomization study.

Background: Non-alcoholic fatty liver disease (NAFLD) and alcohol-related liver disease (ArLD) constitute the primary forms of chronic liver disease, and their incidence is progressively increasing with changes in lifestyle habits. Earlier studies have documented a correlation between the occurrence and development of prevalent mental disorders and fatty liver.

Aim: To investigate the correlation between fatty liver and mental disorders, thus necessitating the implementation of a mendelian randomization (MR) study to elucidate this association.

Chaiqin Chengqi Decoction as an adjuvant treatment for mild/moderately severe hypertriglyceridemic acute pancreatitis: A retrospective study.

Background: Hypertriglyceridemia is the third leading cause of acute pancreatitis (AP), and its incidence is increasing. Due to its relatively insidious etiology, it is easy to be ignored in the early stages. In China, Chaiqin Chengqi Decoction (CQCQD) has long been employed for treating AP.

Graphene Oxide Nanoparticles Combined with CRISPR/Cas9 System Enable Efficient Inhibition of .

We describe an application where graphene oxide nanoparticles (GONs) enable combined inhibition of (PRV) through delivery of a CRISPR/Cas9 system for targeted cleaving of a PRV genome and direct interaction with viral particles. The sheeted GONs could load CRISPR plasmid DNA (pDNA) to form a small sized, near-spheroidal GONs-CRISPR complex, which enables CRISPR pDNA efficient intracellular delivery and transient expression under serum conditions. Cell studies showed that GONs-CRISPR could allow rapid cellular uptake, endolysosomes escape, and nucleus transport within 3 h.

Efficacy of fibrates in the treatment of primary biliary cholangitis: a meta-analysis.

Patients with primary biliary cholangitis (PBC) who respond poorly to ursodeoxycholic acid (UDCA) are increasingly being trialed using fibrates, showing promising results. To further investigate, we performed a meta-analysis to evaluate the benefit of administrating fibrates to patients with PBC. PubMed, EMBASE, and Cochrane library databases were searched using the keywords "bezafibrate", "fenofibrate", "fibrate", "primary biliary cholangitis" and clinical studies involving the use of fibrates in patients with PBC were included.

Gene editing of Duchenne muscular dystrophy using biomineralization-based spCas9 variant nanoparticles.

The CRISPR/Cas9 mediated genome editing have provided a promising strategy to correct multiple mutations of Duchenne muscular dystrophy (DMD). However, the delivery of CRISPR/Cas9 system into mammalian cell for DMD gene editing mainly relies on adeno associated virus (AAV)-mediated transport. Meanwhile, the protospacer adjacent motif (PAM) requirement of wild-typed Cas9 protein causing the target sites for exon splice acceptor site are restricted to limited regions.

Efficient Gene Silencing in Intact Plant Cells Using siRNA Delivered By Functional Graphene Oxide Nanoparticles.

Delivery of small interfering RNA (siRNA) to intact plants for gene silencing mainly relies on viral vectors and Agrobacterium-mediated transformation due to the barrier of intact plant cell wall. Here, we reported that polymer functionalized graphene oxide nanoparticles (GONs) enable siRNA transfer into intact plant cells and bring about efficient gene silencing. We found that sheeted GONs could efficiently load siRNA to form small sized, near-spheroidal GONs-siRNA complex, which could be across the cell wall and internalize in the plant cell.

Simvastatin is Efficacious in Treating Cirrhosis: A Meta-analysis.

Background: Statins can improve prognosis of patients with liver cirrhosis by suppressing inflammation and lowering portal pressure. Here, we performed a meta-analysis to evaluate the clinical efficacy of simvastatin in liver cirrhosis patients.

Methods: We searched PubMed, EMBASE, and Cochrane library databases for randomized controlled trials targeting simvastatin in patients with liver cirrhosis.

Tea Polyphenol Liposomes Overcome Gastric Mucus to Treat Helicobacter Pylori Infection and Enhance the Intestinal Microenvironment.

Infection with () is one of the leading causes of stomach cancer. The ability to treat infection is hampered by a lack of stomach gastric acid environment. This work introduces a nanoliposome that can rapidly adjust the gastric acid environment to ensure a drug's optimal efficacy.

Biomimetic Mineralization-Based CRISPR/Cas9 Ribonucleoprotein Nanoparticles for Gene Editing.

Delivery of the CRISPR/Cas9 ribonucleoprotein (RNP) complex has provided an alternative strategy for the regulation of CRISPR functions, offering a transient and DNA-free means for genomic editing. Chemical methods of delivering the RNPs via nanocomplexes have the potential to address these delivery problems for efficiency, safety, and packaging capacity. Here, we developed a biomimetic mineralization-mediated strategy for efficient DNA-free genome editing by using CRISPR/Cas9 RNPs.

Nitrogen-Doped Carbon Quantum Dots for Preventing Biofilm Formation and Eradicating Drug-Resistant Bacteria Infection.

The development of novel antimicrobial agents is a top priority in the fight against drug-resistant bacteria. Here, we synthesized a green nanoantibiotic, nitrogen-doped carbon quantum dots (N-CQDs) from bis-quaternary ammonium salt (BQAS) as carbon and nitrogen sources. The as-obtained N-CQDs possess high antibacterial activity (>99%) against both methicillin-resistant (MRSA) and Ampicillinresistant bacteria in vitro than some known clinical antibiotics (vancomycin and gentamicin).
