Designing Fast-Moving Antibacterial Microtorpedoes to Treat Lethal Bacterial Biofilm Infections.

Engineering fast-moving microrobot swarms that can physically disassemble bacterial biofilms and kill the bacteria released from the biofilms is a promising way to combat bacterial biofilm infections. Here, we report electrochemical design of AgONO microtorpedoes with outstanding antibacterial performance and meanwhile capable of moving at speeds of hundreds of body lengths per second in clinically used HO aqueous solutions. These fast-moving antibacterial AgONO microtorpedoes could penetrate into and disintegrate the bacterial biofilms and, in turn, kill the bacteria released from the biofilms.

Enzyme-free and rapid colorimetric analysis of osteopontin via triple-helix aptamer probe coupled with catalytic hairpin assembly reaction.

Background: Osteopontin (OPN) is closely associated with tumorigenesis, growth, invasion, and immune escape and it serves as a plasma biomarker for hepatocellular carcinoma (HCC). Nevertheless, the accurate and rapid detection of low-abundance OPN still poses significant challenges. Currently, the majority of protein detection methods rely heavily on large precision instruments or involve complex procedures.

Ultrasound-enhanced nano catalyst with ferroptosis-apoptosis combined anticancer strategy for metastatic uveal melanoma.

Uveal melanoma is the most common primary ocular tumor owing to its highly invasive and metastatic characteristics. Currently, standard clinical treatment has an unsatisfied curative effect due to the lack of an effective approach to inhibit the tumor metastasis. Therefore, it is necessary to develop a new strategy that can both restraint local tumors and suppress the ocular tumor metastasis.

Gallic Acid Ameliorates Cognitive Impairment Caused by Sleep Deprivation through Antioxidant Effect.

Sleep deprivation (SD) has a profound impact on the central nervous system, resulting in an array of mood disorders, including depression and anxiety. Despite this, the dynamic alterations in neuronal activity during sleep deprivation have not been extensively investigated. While some researchers propose that sleep deprivation diminishes neuronal activity, thereby leading to depression.

Structural and molecular basis of pollen germination.

Pollen germination is a prerequisite for double fertilization of flowering plants. A comprehensive understanding of the structural and molecular basis of pollen germination holds great potential for crop yield improvement. The pollen aperture serves as the foundation for most plant pollen germination and pollen aperture formation involves the establishment of cellular polarity, the formation of distinct membrane domains, and the precise deposition of extracellular substances.

Biocompatible Gallium Nanodots against Drug-Resistant Bacterial Pneumonia and Liver Abscess.

Resistant bacterial infection remains a severe public health threat, and conventional antibiotic drugs work poorly in effectively treating infectious diseases. Here, we developed gallium-based nanodots (Ga NDs), consisting of specific disruption of bacterial iron ability, to treat multidrug-resistant (MDR) Gram-negative bacteria-infected diseases. The Ga NDs significantly suppress the proliferation of two typical MDR bacteria strains ( and ESBL ) compared with clinically used antibacterial drugs, including penicillin and levofloxacin.

S100A family is a group of immune markers associated with poor prognosis and immune cell infiltration in hepatocellular carcinoma.

It is urgent to identify novel biomarker and valid target to effectively diagnose, treat or predict the prognosis of HCC.

Bioinspired pH-Responsive Microalgal Hydrogels for Oral Insulin Delivery with Both Hypoglycemic and Insulin Sensitizing Effects.

The oral form of insulin is more convenient and has better patient compliance than subcutaneous or intravenous insulin. Current oral insulin preparations, however, cannot overcome the enzyme barrier, chemical barrier, and epithelial barrier of the gastrointestinal tract completely. In this study, a microalgae-based oral insulin delivery strategy (CV@INS@ALG) was developed using (CV)-based insulin delivery system cross-linking with sodium alginate (ALG).

Promoting genotype-independent plant transformation by manipulating developmental regulatory genes and/or using nanoparticles.

This review summarizes the molecular basis and emerging applications of developmental regulatory genes and nanoparticles in plant transformation and discusses strategies to overcome the obstacles of genotype dependency in plant transformation. Plant transformation is an important tool for plant research and biotechnology-based crop breeding. However, Plant transformation and regeneration are highly dependent on species and genotype.

Opportunities and challenges of natural killer cell-derived extracellular vesicles.

Extracellular vesicles (EVs) are increasingly recognized as important intermediaries of intercellular communication. They have significant roles in many physiological and pathological processes and show great promise as novel biomarkers of disease, therapeutic agents, and drug delivery tools. Existing studies have shown that natural killer cell-derived EVs (NEVs) can directly kill tumor cells and participate in the crosstalk of immune cells in the tumor microenvironment.

Gestational psittacosis causes severe pneumonia and miscarriage: A case report and literature review.

Psittacosis is an uncommon zoonotic illness, and gestational psittacosis is even rarer. The clinical signs and symptoms of psittacosis are varied, often overlooked, and swiftly identified by metagenomic next-generation sequencing. We recorded the case of a 41-year-old pregnant woman with psittacosis where the disease was not detected early on, resulting in severe pneumonia and fetal miscarriage.

Host-Defense-Peptide-Mimicking β-Peptide Polymer Acting as a Dual-Modal Antibacterial Agent by Interfering Quorum Sensing and Killing Individual Bacteria Simultaneously.

Host defense peptides (HDPs) are one of the potentially promising agents for infection diseases due to their broad spectrum and low resistance rate, but their clinical applications are limited by proteolytic instability, high-cost, and complicated synthesis process. Here, we report a host-defense-peptide-mimicking β-peptide polymer that resists proteolysis to have enhanced the activity under physiological conditions, excellent antimicrobial efficiency even at high density of bacteria, and low cost for preparation. The β-peptide polymer demonstrated quorum sensing (QS) interference and bactericidal effect against both bacterial communities and individual bacterium to simultaneously block bacterial communication and disrupt bacterial membranes.

Quercetin Inhibits Intrahepatic Cholangiocarcinoma by Inducing Ferroptosis and Inhibiting Invasion via the NF-[Formula: see text]B Pathway.

Intrahepatic cholangiocarcinoma (ICC) is a rare, highly fatal hepatobiliary malignancy, with very limited treatment options and, consequently, a poor prognosis. Recently, emerging evidence has suggested the potential of quercetin (QE) for use in cancer therapy. The purpose of this study is to investigate whether QE could inhibit ICC.

Protein-free, ultrasensitive miRNA analysis based on an entropy-driven catalytic reaction switched on a smart-responsive DNAzyme dual-walker amplification strategy.

MicroRNAs (miRNAs), useful biomarkers for cancer diagnosis, play an important role in tumorigenesis and progression, but many of the current analysis methods can suffer from excessive protease dependence, being time-consuming and unsatisfactory performance. Therefore, a reliable sensing strategy for the protein-free, ultrasensitive analysis of tumor-associated miRNAs is desired. The proposed dual-walker biosensing strategy based on an entropy-driven catalytic (EDC) walker coupled with a smart-responsive DNAzyme walker was demonstrated for the dual-amplification detection of miRNA-21.
