Article Synopsis
  • - Cocaine abuse disrupts the blood-brain barrier (BBB) by decreasing the expression of glucose transporter 1 (GLUT1) in brain cells, which leads to cognitive issues and increased BBB leakage.
  • - The study reveals that cocaine elevates the level of miR-320a, which then reduces GLUT1 expression through the activation of the beta 2-adrenergic receptor (ADRB2).
  • - Melatonin can help counteract cocaine-induced BBB disruption and cognitive impairment by boosting GLUT1 expression through a specific signaling pathway, suggesting it could be a potential treatment for cocaine-related problems.

Identifying interactions between long non-coding RNAs (lncRNAs) and microRNAs (miRNAs) provides a new perspective for understanding regulatory relationships in plant life processes. Recently, computational methods based on graph neural networks (GNNs) have been widely employed to predict lncRNA-miRNA interactions (LMIs), which compensate for the inadequacy of biological experiments. However, the low-semantic and noise of graph limit the performance of existing GNN-based methods.

Basal-like breast cancer (BLBC) is the most malignant subtype of breast cancer because of its aggressive clinical behaviour and lack of effective targeted agents. Krüppel-like factor 5 (KLF5) is an oncogenic transcription factor that is highly expressed in BLBC. The deubiquitinase (DUB) BRCA1-associated protein 1 (BAP1) stabilizes KLF5 and promotes BLBC growth and metastasis.

Low-dimensional organic-inorganic hybrid lead halide perovskites have attracted much interest in solid-state lighting and displays, but the toxicity and instability of lead halide are obstacles to their industrial applications, which must be overcome. As an alternative, Cu(I)-based hybrid metal halides have emerged as a new type of luminescent material owing to their diversified structure, adjustable luminescence, low toxicity and low cost. Herein, we report three one-dimensional (1D) hybrid Cu(I)-based halides with the general formula ACuBr (A = [(Me)-Pipz] and [BuDA] and [TMEDA]).

Pressure injuries (PIs) are a common healthcare problem worldwide and are considered to be the most expensive chronic wounds after arterial ulcers. Although the gross factors including ischemia-reperfusion (I/R) have been identified in the etiology of PIs, the precise cellular and molecular mechanisms contributing to PIs development remain unclear. Various forms of programmed cell death including apoptosis, autophagy, pyroptosis, necroptosis and ferroptosis have been identified in PIs.

Commercially available rare-earth-doped inorganic oxide materials have been widely applied as X-ray scintillators, but the fragile characteristics, high detection limit, and harsh preparation condition seriously restrict their wide applications. Furthermore, it remains a huge challenge to realize X-ray flexible imaging technology for real-time monitoring of the curving interface of complex devices. To address these issues, we herein report two isostructural cuprous halides of zero-dimensional (0D) [AEPipz]CuX·X·HO (AEPipz = -aminoethylpiperazine, X = Br and I) with controllable size to nanosize crystal as highly efficient scintillators toward flexible X-ray imaging.

Kuiper's statistic is a good measure for the difference of ideal distribution and empirical distribution in the goodness-of-fit test. However, it is a challenging problem to solve the critical value and upper tail quantile, or simply Kuiper pair, of Kuiper's statistics due to the difficulties of solving the nonlinear equation and reasonable approximation of infinite series. In this work, the contributions lie in three perspectives: firstly, the second order approximation for the infinite series of the cumulative distribution of the critical value is used to achieve higher precision; secondly, the principles and fixed-point algorithms for solving the Kuiper pair are presented with details; finally, finally, a mistake about the critical value for in Kuiper's distribution table has been labeled and corrected where is the sample capacity and is the upper tail quantile.

Article Synopsis
  • - The study investigates the role of endothelial cell-derived microvascular basement membrane (BM) components in maintaining the blood-brain barrier (BBB) and reveals that knocking out the gene Atg7 in endothelial cells disrupts the interaction between astrocytes and microvessels.
  • - In mice lacking Atg7 in endothelial cells, astrocytic endfeet detach from blood vessels, leading to BBB leakage and decreased coverage of astrocytes due to reduced fibronectin expression.
  • - Findings suggest that Atg7 is crucial for regulating fibronectin production in endothelial cells, which is necessary for proper astrocyte adhesion to microvessels and overall BBB homeostasis.
