miR-Cabiner: A Universal microRNA Sensing Platform Based on Self-Stacking Cascaded Bicyclic DNA Circuit-Mediated CRISPR/Cas12a.

CRISPR/Cas12a-based diagnostics have great potential for sensing nucleic acids, but their application is limited by the sequence-dependent property. A platform termed miR-Cabiner (a universal NA sensing platform based on self-stacking scaded cyclic DA circuit-mdiated CISPR/Cas12a) is demonstrated herein that is sensitive and universal for analyzing miRNAs. This platform combines catalytic hairpin assembly (CHA) and hybrid chain reaction (HCR) into a unified circuit and finally cascades to CRISPR/Cas12a.

Development and validation of disulfidptosis-related genes signature for patients with glioma.

Bioorthogonal Engineering of Bacterial Outer Membrane Vesicles for NIR-II Fluorescence Imaging-Guided Synergistic Enhanced Immunotherapy.

The efficacy of immunotherapy in treating triple-negative breast cancer (TNBC) has been restricted due to its low immunogenicity and suppressive immune microenvironment. Bacterial outer membrane vesicles (OMVs) have emerged as innovative immunotherapeutic agents in antitumor therapy by stimulating the innate immune system, but intricate modifications and undesirable multiple dose administration severely hinder their utility. Herein, a two-step bacterial metabolic labeling technique was utilized for the bioorthogonal engineering of OMVs.

Interactions Between Ferroptosis and Oxidative Stress in Ischemic Stroke.

Ischemic stroke is a devastating condition that occurs due to the interruption of blood flow to the brain, resulting in a range of cellular and molecular changes. In recent years, there has been growing interest in the role of ferroptosis, a newly identified form of regulated cell death, in ischemic stroke. Ferroptosis is driven by the accumulation of lipid peroxides and is characterized by the loss of membrane integrity.

miR-630 as a therapeutic target in pancreatic cancer stem cells: modulation of the PRKCI-Hedgehog signaling axis.

Background: MicroRNAs (miRNAs) are critical regulators of cancer progression, prompting our investigation into the specific function of miR-630 in pancreatic cancer stem cells (PCSCs). Analysis of miRNA and mRNA expression data in PCSCs revealed downregulation of miR-630 and upregulation of PRKCI, implying a potential role for miR-630 in PCSC function and tumorigenicity.

Results: Functional assays confirmed that miR-630 directly targets PRKCI, leading to the suppression of the Hedgehog signaling pathway and consequent inhibition of PCSC self-renewal and tumorigenicity in murine models.

Electroacupuncture may alleviate inflammatory pain by downregulating the expression of P2Y receptor in the primary somatosensory cortex.

Observation of a Novel Interligand Chiral Arrangement in Metal Nanoclusters and Its Implication in Resisting Racemization.

Given the scientifically significant importance of studying the chirality of clusters, the challenges of synthesizing chiral clusters are progressively surmounted. However, the racemization of clusters is unavoidable, and it limits the development of their follow-on chiral applications. To address this issue, chiral thiols are synthesized and used for the construction of high-stability optically pure nanoclusters in this work.

A single-gold-atom addition regulates sharp redshift in the fluorescence of atomically precise nanoclusters.

The manipulation of emission peaks at the atomic level and the investigation of the fluorescent origin mechanism are important issues. In this study, a phosphine-mediated modification method was employed on Au(TBBT) nanocluster to produce a new gold nanocluster Au(TBBT)(TPP). The structural comparison revealed that Au(TBBT)(TPP) has a structural framework similar to that of Au(TBBT) except for the reconstruction of its surface motifs, the addition of one gold atom into the kernel, and local structural distortion.

Parameter identification of solar photovoltaic (PV) cells is crucial for the PV system modeling. However, finding optimal parameters of PV models is an intractable problem due to the highly nonlinear characteristics between currents and voltages in different environments. To address this problem, whale optimization algorithm (WOA)-based meta-heuristic algorithm has turned out to be a feasible and effective approach.

Electroacupuncture pretreatment enhances the calcium efflux activity of Na/Ca exchanger to attenuate cerebral injury by PI3K/Akt-mediated NCX1 upregulation after focal cerebral ischaemia.

Electroacupuncture pretreatment is considered as an optimal strategy for inducing cerebral ischaemic tolerance. However, the underlying neuroprotective mechanism of this approach has never been explored from the perspective of calcium homeostasis. Intracellular calcium overload is a key inducer of cascade neuronal injury in the early stage after cerebral ischaemia attack and the Na/Ca exchanger (NCX) is the main plasma membrane calcium extrusion pathway maintaining post-ischaemic calcium homeostasis.
