The present study summarizes the formation and characterization of multilayers of polyacrylonitrile (PAN) membranes with β-cyclodextrin derivatives in order to be potentially interesting for triclosan (TR) controlled delivery with antibacterial purposes, as well as, for the removal of TR from wastewater. With this object, cationic and anionic branched β-cyclodextrins (bβCDs) were incorporated by layer-by-layer (LbL) process onto previously synthesized and hydrolyzed PAN membranes. FTIR, XPS and labelling with fluoresceinamine (FA) let to study the formation and stability of the prepared multilayered systems. TR is a widely used antibacterial and antifungal agent with proven ability to inhibit bacterial growth that, however, recently has shown a potential toxicity. The ability of obtained bβCDs/PAN multilayered membranes to retain TR in water was evaluated by two different loading procedures. The delivery kinetic profile of TR from loaded membranes was also analyzed showing the maximum release in the first 24h.

Purpose: RING Finger 187 (RNF187) has recently emerged as a potential contributor to tumorigenesis. However, a comprehensive pan-cancer analysis of RNF187 in human tumors has not been undertaken until now.
Methods: Our study aims to investigate RNF187 expression across 33 different types of human tumors, utilizing data from the TCGA and GTEx databases.

Glioblastoma (GBM) persists as a highly fatal malignancy, with current clinical treatments showing minimal progress over years. Interstitial photodynamic therapy (iPDT) holds promise due to its minimally invasive nature and low toxicity but is impeded by poor photosensitizer penetration and inadequate GBM targeting. Here, we developed a biomimetic pure-drug nanomedicine (MM@CT), which co-assembles the photosensitizer chlorin e6 (Ce6) and the first-line chemotherapeutic drug (temozolomide, TMZ) for GBM, then camouflaged with macrophage membranes.

Bisphenol A (BPA) is a common endocrine disruptor chemical that is widely used in the production of food plastic packaging, and it has been shown to potentially harm the reproductive system. However, the specific mechanism by which BPA induces apoptosis of Leydig cells (LCs) and inhibits testosterone synthesis in these cells is unclear. In the present study, TM3 cells were used as an experimental model in combination with a reactive oxygen species (ROS) scavenger (N-acetylcysteine), Caspase-3 inhibitor (Ac-DEVD-CHO), autophagy activator (Torin2), and autophagy inhibitor (Chloroquine) to investigate the potential mechanisms by which BPA causes TM3 cell damage in vitro.

Lithium-ion batteries (LIBs) have broad application prospects in many fields because of their high energy density. However, the poor heat resistance of polyolefin membranes and uneven lithium deposition result in battery failure and even infamous thermal runaway behavior. To improve the intrinsic safety of batteries, fire-retardant, thermally conductive, electrospinning strategies are employed to acquire a functional polyacrylonitrile (PAN) nanofiber separator (PAN@FBN/TPP) containing modified boron nitride (FBN) and triphenyl phosphate (TPP).

The study of the mechanism of oligoasthenospermia, which is a major cause of male infertility, has been the focus of research in the field of male reproduction. TAp73, a member of the p53 family of oncogenes, is endowed with tumor-suppressing activity due to its structural and functional homology with p53. It has been found that TAp73, plays a key role in spermatogenesis and maintaining male reproduction.
