Resonantly Enhanced Hybrid Wannier-Mott-Frenkel Excitons in Organic-Inorganic Van Der Waals Heterostructures.

Hybrid excitons formed via resonant hybridization in 2D material heterostructures feature both large optical and electrical dipoles, providing a promising platform for many-body exciton physics and correlated electronic states. However, hybrid excitons at organic-inorganic interface combining the advantages of both Wannier-Mott and Frenkel excitons remain elusive. Here, hybrid excitons are reported in the copper phthalocyanine/molybdenum diselenide (CuPc/MoSe) heterostructure (HS) featuring strong molecular orientation dependence by low-temperature photoluminescence and absorption spectroscopy.

Mammalian nucleophagy: process and function.

The nucleus is a highly specialized organelle that houses the cell's genetic material and regulates key cellular activities, including growth, metabolism, protein synthesis, and cell division. Its structure and function are tightly regulated by multiple mechanisms to ensure cellular integrity and genomic stability. Increasing evidence suggests that nucleophagy, a selective form of autophagy that targets nuclear components, plays a critical role in preserving nuclear integrity by clearing dysfunctional nuclear materials such as nuclear proteins (lamins, SIRT1, and histones), DNA-protein crosslinks, micronuclei, and chromatin fragments.

The Role of SIRT1-BDNF Signaling Pathway in Fluoride-Induced Toxicity for Glial BV-2 Cells.

Chronic fluorosis is often accompanied by neurological symptoms, leading to attention, memory and learning ability decline and causing tension, anxiety, depression, and other mental symptoms. In the present study, we analyzed the molecular mechanisms of SIRT1-BDNF regulation of PI3K-AKT, MAPK, and FOXO1A in F-treated BV2 cells. The cytotoxic effect of sodium fluoride (NaF) on BV2 cells was assessed using Cell Counting Kit-8 (CCK-8), crystal violet, and 5-ethynyl-2'-deoxyuridine (EdU) staining.

Discovery of novel dual tubulin and MMPs inhibitors for the treatment of lung cancer and overcoming drug resistance.

Nowadays, hybrid molecule with dual targets activity or effect is regarded as an effective strategy for combating the drug resistance development in cancer therapy. Herein, novel of bifunctional conjugates targeting tubulin and MMPs inhibitors were synthesized. Among them, 15j exhibited robust anticancer activity in vitro and in vivo, with IC values of 0.

Digital Frequency Customized Relieving Sound for Chronic Subjective Tinnitus Management: Prospective Controlled Study.

Background: Tinnitus is a major health issue, but currently no tinnitus elimination treatments exist for chronic subjective tinnitus. Acoustic therapy, especially personalized acoustic therapy, plays an increasingly important role in tinnitus treatment. With the application of smartphones, personalized acoustic stimulation combined with smartphone apps will be more conducive to the individualized treatment and management of patients with tinnitus.
