Multidrug resistance (MDR) infectious wounds are a major concern due to drug resistance, leading to increased patient morbidity. Lichenysin (LCN), a lipopeptide and biosurfactant obtained from certain strains of , has demonstrated an excellent antimicrobial property. The present study focuses on the fabrication and comprehensive evaluation of LCN-incorporated poly(vinyl alcohol) (PVA)/polycaprolactone (PCL)-based nanofiber scaffolds using an electrospinning technique as a potential wound healing biomaterial for the treatment of MDR infectious wounds in diabetic rats.

Owing to the "cold" tumor immune microenvironment of prostate cancer, immune-targeting agents have shown limited efficacy in patients with advanced prostate cancer, highlighting the need for new therapies with novel mechanisms of action. In this context, T-cell engagers (TCEs), which induce T-cell-mediated killing of cancer cells by binding the CD3 receptor on T cells and a specific tumor antigen expressed on malignant cells, represent a promising therapeutic option. Multiple studies have explored the use of TCEs in previously treated patients with metastatic castration-resistant prostate cancer, and several ongoing trials are currently assessing novel TCEs either as single agents or in combinatorial regimens with molecules with a distinct mechanism of action (eg, androgen receptor pathway inhibitors and other immune-targeting agents).

Methods: Binding affinity of naringenin (NAR) to mitochondria complex II (CΙΙ) subunits, sirtuin3 (SIRT3), tumor necrosis factor associate protein 1(TRAP1), and succinate receptor (SUCNR1) was studied by molecular docking.

Acute kidney injury (AKI) lacks a definitive therapeutic approach beyond supportive care. One significant pathological mechanism involves the regulated death of tubular epithelial cells; however, the regulatory mechanisms underlying this cell death pathway require further investigation. The N6-methyladenosine (m6A) modification, recognized as the most prevalent modification in eukaryotes, plays a critical role in the regulatory processes associated with AKI.

Mechanisms for absorption improvement of drugs with low water-solubility by self-microemulsifying drug delivery system (SMEDDS) are still controversial except for solubility improvement. We attempted to clarify the mechanisms by utilizing model drugs classified as biopharmaceutics classification system class II. In the in-vitro transport study for microemulsions (MEs) formed from SMEDDS, the permeation clearance (CL) calculated based on free drug concentrations in MEs, was significantly larger than the CL for aqueous solution.
