Simple and sensitive monitoring of polycyclic aromatic hydrocarbons in edible oils by polydimethylsiloxane/pyrazine-based hyper-crosslinked polymer coated stir bar sorptive extraction followed by gas chromatography-mass spectrometry detection.

Background: Edible oils are susceptible to contamination with polycyclic aromatic hydrocarbons (PAHs) throughout production, storage, and transportation processes due to their lipophilic nature. The necessity of quantifying PAHs present in complex oil matrices at trace levels, which bind strongly to impurities in oil matrices, poses a major challenge to the accurate quantification of these contaminants. Therefore, the development of straightforward and effective methods for the separation and enrichment of PAHs in oil samples prior to instrumental analysis is paramount to guaranteeing food safety.

EGFP/RFP-based FRET sensors for botulinum neurotoxin A biological activity detection and methodological validation.

Background: Botulinum neurotoxin type A (BoNT/A) is the most potent and prevalent neurotoxin known to cause botulism, and is also widely used in medical and cosmetic applications. The detection of BoNT/A is of great significance for botulism diagnosis and drug potency determination. Currently, the mouse bioassay (MBA) has long been the gold standard method but has disadvantages of ethical concerns, long testing duration, and high costs.

Point of view: Challenges in implementation of new immunotherapies for Alzheimer's disease.

The advancement of disease-modifying treatments (DMTs) for Alzheimer's disease (AD), along with the approval of three amyloid-targeting therapies in the US and several other countries, represents a significant development in the treatment landscape, offering new hope for addressing this once untreatable chronic progressive disease. However, significant challenges persist that could impede the successful integration of this class of drugs into clinical practice. These challenges include determining patient eligibility, appropriate use of diagnostic tools and genetic testing in patient care pathways, effective detection and monitoring of side effects, and improving the healthcare system's readiness by engaging both primary care and dementia specialists.

Bupivacaine multivesicular liposomes/meloxicam nanocrystals in a thermosensitive gel adapted to the "microenvironment" for long-term analgesia.

Inflammatory factor production can create acidic environments, limiting drug delivery. In this study, we developed a novel injectable formulation comprising bupivacaine multivesicular liposomes of high osmotic pressure (H-MVL) and meloxicam nanocrystals (MLX) in a thermosensitive gel (H-MVL/MLX@GEL) adapted to the microenvironment for long-term postoperative analgesia.

Traditional Chinese medicines (TCMs) hold significant potential for the management of HF.

Recent advances in the dual effects of activin A on tumors.

Activin A, a gonadal protein, not only stimulates the pituitary to secrete follicle-stimulating hormone (FSH) but also plays a crucial role in regulating various cell behaviors, such as cell proliferation, differentiation, apoptosis, migration, and invasion. Studies have shown an association between activin A expression and tumor progression, highlighting its dual role in cancer. Similar to transforming growth factor-beta (TGF-β), activin A can have both pro-tumor and anti-tumor effects, for instance, it inhibits the migration of lung adenocarcinoma cells, while promotes the migration of triple-negative breast cancer cells.
