Mycotoxin contamination is an important issue for food safety and the environment. Removing mycotoxins from food without losing nutrients and flavor components remains a challenge. In this study, a novel strategy was proposed for the targeted removal of aflatoxin B (AFB) from peanut oil using an amphipathic enzyme-metal hybrid nanoreactor (PL-GOx-FeO@COF) constructed with covalent organic frameworks (COFs) which can selectively adsorb AFB. Due to the confined space provided by COFs and the proximity effect between GOx and FeO, the detoxification of AFB is limited in the nanoreactor without affecting the composition and properties of the oil. The detoxification efficiency of AFB in the chemoenzymatic cascade reaction catalyzed by PL-GOx-FeO@COF is six times higher than that of the combination of free GOx and FeO. The AFB transformation product has nontoxicity to kidney and liver cells. This study provides a powerful tool for the targeted removal of mycotoxins from edible oils.

Substance use disorders (SUDs) present a critical global health challenge, as current treatment options often prove insufficient, particularly for substances like ketamine and methamphetamine. In this study, we developed a novel immunotherapeutic strategy utilizing protein-free, polymer-based vaccines, with hyperbranched polyethylenimine (Hb-PEI) as a carrier to enhance immune specificity and remove the production of non-specific antibodies. Haptens for ketamine and methamphetamine were covalently conjugated to the Hb-PEI carrier, along with the Toll-like receptor (TLR) 7/8 agonist 1V209, to stimulate targeted humoral immune responses.

is a vital zoonotic pathogen known for its extensive drug resistance and ability to form biofilms, which contribute to its antibiotic resistance. In this study, the phage vB_C4, specifically targeting , was isolated and subjected to bioinformatic analysis and bacteriostatic activity assays. The combination of phage vB_C4 with antibiotics such as cephalothin and cefoxitin, which target the bacterial cell wall, resulted in a significantly enhanced bacteriostatic effect compared to either the phage or antibiotics alone.

Reticulocyte Binding Protein Homologue (RH5), a leading malaria vaccine candidate, is essential for erythrocyte invasion by the parasite, interacting with the human host receptor, basigin. RH5 has a small number of polymorphisms relative to other blood-stage antigens, and studies have shown that vaccine-induced antibodies raised against RH5 are strain-transcending, however most studies investigating RH5 diversity have been done in Africa. Understanding the genetic diversity and evolution of malaria antigens in other regions is important for their validation as vaccine candidates.

Metformin (MET), a commonly prescribed medication for managing type 2 diabetes, has demonstrated various beneficial effects beyond its primary anti-diabetic efficacy. However, the mechanism underlying MET activity and its distribution within organelles remain largely unknown. In this study, we integrate multiple technologies, including chemical labeling, immunostaining, and high-resolution microscopy imaging, to visualize the accumulation of MET in organelles of cultured cells.

Background: In renal cell carcinoma (RCC), skin metastases (SMs) occur in only 3.3% of cases and are even rarer as an initial manifestation of the disease. Although combination therapy with immune checkpoint inhibitors (ICIs) and targeted agents is the current standard of care, access to these treatments may be limited in certain regions due to cost constraints.
