Vaginal eubiosis is characterised by beneficial lactobacillus-dominated microbiota. In contrast, vaginal dysbiosis (e.g. bacterial vaginosis, BV), characterised by an overgrowth of multiple anaerobes, is associated with an increased risk of adverse urogenital and reproductive health outcomes. A major distinguishing feature between the vaginal environment in states of eubiosis and dysbiosis is a high concentration of lactic acid, produced by lactobacilli, that acidifies the vagina in eubiosis versus a sharp drop in lactic acid and an increase in pH in dysbiosis. Here we review the antimicrobial, antiviral and immunomodulatory properties of lactic acid and the use of lactic acid and lactobacilli probiotics in preventing or treating BV.

Introduction: Wound treatment is a significant health burden in any healthcare system, which requires proper management to minimize pain and prevent bacterial infections that can complicate the wound healing process.
Rationale: There is a need to develop innovative therapies to accelerate wound healing cost-effectively. Herein, two polymer-based nanofibrous systems were developed using poly-lactic-co-glycolic-acid (PLGA) and polyvinylpyrrolidone (PVP) loaded with a combination of an antibiotic (Fusidic acid, FA) and a local anesthetic (Lidocaine, LDC) via electrospinning technique for an expedited healing process by preventing bacterial infections while reducing the pain sensation.

To enhance exploration on tumor stem-like cells (TSCs) without altering their cellular biological characteristics, researchers advocate for application of single-cell-derived tumor-spheres (STSs). TSCs are regulated by their surrounding microenvironment, making it crucial to simulate a tumor microenvironment to facilitate STS formation. Recently, exosomes that originated from the tumor microenvironment have emerged as a promising approach for mimicking the tumor microenvironment.

Triterpenoids are known for their promising biological activities, and there is a growing focus on green extraction methods for these compounds. In this study, ultrasound-assisted deep eutectic solvents were employed to extract triterpenoids from persimmon leaves, with choline chloride-lactic acid identified as an effective green solvent. The extraction conditions were carefully optimized using response surface methodology, resulting in an extraction efficiency of 12.
