Enhanced Anticancer Efficacy of Alkaline Plasma-Activated Water through Augmented RONS Production.

Despite notable advances in anticancer drug development, their manufacture and use pose environmental and health risks due to toxic byproducts, drug residue contamination, and cytotoxicity to normal cells. Therefore, developing cost-effective anticancer treatments with fewer toxic side effects and higher selectivity is essential to the advancement of highly effective anticancer therapies. Plasma-activated water (PAW) offers a green alternative to conventional chemical treatments as it reverts to water within days.

Catalytic insights of acetolactate synthases from different bacteria.

Acetolactate synthase (ALS) is an essential enzyme involved in the biosynthesis of platform chemicals acetoin and 2,3-butanediol in several microorganisms. In this study, we investigated the catalytic differences among three bacterial ALSs involved in the ligation of two molecules of pyruvate or 2-ketobutyrate. Based on the findings, we predicted three amino acid residues in each enzyme that caused a discrepancy in accordance with the multi-sequence alignment and molecular docking experiments: I398, A402, and T480 in Bacillus subtilis ALS; V400, Y404, and S482 in Listeria seleigeri serovar 1/2b ALS; and M394, H398, and G476 in Klebsiella pneumoniae ALS.

Linear regression with standard errors clustered at the city level was employed.

Enhancing substrate specificity of microbial transglutaminase for precise nanobody labeling.

transglutaminase (smTG) can be used for site-specific labeling of proteins with chemical groups. Here, we explored the use of modified smTG for the biosynthesis of nanobody-fluorophore conjugates (NFC). smTG catalyzes the conjugation of acyl donors containing glutamine with lysine-containing acceptors, which can lead to non-specific cross-linking.

Progressive Optic Neuropathy in Hydrocephalic Ccdc13 Mutant Mice Caused by Impaired Axoplasmic Transport at the Optic Nerve Head.

Purpose: Optic nerve head (ONH) atrophy is frequently associated with hydrocephalic conditions. Cerebrospinal fluid (CSF)-containing meninges form a subarachnoid space that terminates at the ONH, which physically impacts it. This study aims to characterize optic neuropathy in congenital hydrocephalic mice with genetic disruption of the Ccdc13 gene.

Aluminum decreases cadmium accumulation by down-regulating the expression of cadmium-related genes in wheat.

Aluminum (Al) and cadmium (Cd) often coexist in the acidic soils of southern China, but their interactive effects remain unclear. In this study, this was examined in Al-resistant (Atlas 66) and Al-sensitive (Scout 66) wheat cultivars. The results showed that Al significantly alleviated the root growth of Al-tolerant Atlas 66 under Cd stress but had no effect on the root growth of Al-sensitive Scout 66 or the shoot growth of both cultivars.

Long-Term Stable EuO-Loaded Dendritic Mesoporous Silica Nanoprobes with Coordination-Enhanced Photoluminescence for Ultrasensitive Lateral Flow Immunoassay.

Inorganic lanthanide nanomaterials as photoluminescent biolabels have attracted increasing attention due to their superior physicochemical properties. However, unstable conjugation of inorganic lanthanide nanomaterials with biological function units (such as antibodies) induces instability of conjugated complexes in aqueous solution, limiting their clinical application. In this study, we developed a rapid point-of-care testing (POCT) platform strategy based on coordination-enhanced time-resolved luminescence of specially nanostructural lanthanide particles for lateral flow immunoassay (CE-TRFIA).

Weight-Based Standardized Sugammadex Dosing in Pediatrics: A Quality Improvement Initiative to Improve Compliance with Dosing Guidelines and Reduce Waste and Cost.

Methods: Sugammadex vials were fractionated into 25, 50, or 100 mg aliquots, which would be distributed to anesthesia staff by pharmacy staff in approximate 2 mg/kg of actual body weight doses (±10%). We analyzed changes in sugammadex waste and dosing practices 1/1/2019 to 3/15/2023 pre/postintervention (4/1/2021). We gauged dose appropriateness using last train of four (TOF) prior to sugammadex administration.

OsRAV1 Regulates Seed Vigor and Salt Tolerance During Germination in Rice.

Seed vigor is a complex trait encompassing seed germination, seedling emergence, growth, seed longevity, and stress tolerance, all are crucial for direct seeding in rice. Here, we report that the AP2/ERF transcription factor OsRAV1 (RELATED TO ABI3 AND VP1) positively regulates seed germination, vigor, and salt tolerance. Additionally, OsRAV1 was differently expressed in embryo and endosperm, with the OsRAV1 localized in the nucleus.

Diabetic peripheral neuropathy based on Schwann cell injury: mechanisms of cell death regulation and therapeutic perspectives.

Diabetic peripheral neuropathy (DPN) is a complication of diabetes mellitus that lacks specific treatment, its high prevalence and disabling neuropathic pain greatly affects patients' physical and mental health. Schwann cells (SCs) are the major glial cells of the peripheral nervous system, which play an important role in various inflammatory and metabolic neuropathies by providing nutritional support, wrapping axons and promoting repair and regeneration. Increasingly, high glucose (HG) has been found to promote the progression of DPN pathogenesis by targeting SCs death regulation, thus revealing the specific molecular process of programmed cell death (PCD) in which SCs are disrupted is an important link to gain insight into the pathogenesis of DPN.

Changes in the gut microbiota of patients with sarcopenia based on 16S rRNA gene sequencing: a systematic review and meta-analysis.

Introduction: Sarcopenia, an age-related disease, has become a major public health concern, threatening muscle health and daily functioning in older adults around the world. Changes in the gut microbiota can affect skeletal muscle metabolism, but the exact association is unclear. The richness of gut microbiota refers to the number of different species in a sample, while diversity not only considers the number of species but also the evenness of their abundances.

Investigation of the Driving Force of Replacing Adsorbed Hydrocarbons by CO in Organic Matter from an Energy Perspective.

Carbon dioxide (CO) has been widely used to enhance the recovery of adsorbed hydrocarbons from the organic matter (OM) in shale formations. To reveal the driving force of replacing adsorbed hydrocarbons from OM by CO, we performed molecular dynamics (MD) simulations of the replacement process and calculated the interaction forces between CO and hydrocarbons. In addition, based on the umbrella sampling method, steered MD simulations were performed, and the free energy profiles of hydrocarbons were obtained using the weighted histogram analysis method.
