Xinjiang Key Laboratory of Biological Resources and Genetic Engineering, College of Life Science and Technology, Xinjiang University, Urumqi 830017, China. Electronic address:
This study developed antimicrobial peptides (AMPs) from quinoa with high antibacterial activity and stability by mixed-bacteria fermentation. Furthermore, among 9 peptide fractions purified by membrane separation and chromatography, F1 could effectively inhibit the growth and propagation of bacterial microorganisms in apple juice. Subsequently, F1 identified LC-MS/MS as 95 peptides, molecular weights 494.

The inclusion of artificial food additives such as vanillin in infant formula should be strictly monitored to mitigate potential negative impacts on the dietary habits and health of infants. This raises a necessity of an accurate inspection and prompt feedback of vanillin in infant foods. In this study, colorimetric and fluorescent dual-mode assays based on CuNS/FeO@MIPs were established to detect vanillin selectively and sensitively.

Electronic address:
A novel biomimetic molecular imprinted polymer chip with fluorescence (FL) and structural (STR) states, inspired by color patterns of chameleon skin, is fabricated for detecting diethylstilbestrol (DES). The chip features a regularly structured, non-closed-packed (NCP) colloidal photonic crystal (CPC) lattice made monodisperse MIP spheres containing fluorescence poly ionic liquid (FPIL) pigments. The FL color originates from FPIL pigments and is further enhanced by the Purcell effect, while the STR color results from the periodic arrangement of the NCP CPC structure.

J Acquir Immune Defic Syndr
December 2024
Division of Nephrology, Albert Einstein College of Medicine, Montefiore Health System, Bronx, NY.
Background: The Veterans Aging Cohort Study (VACS) Index is a summary measure of routinely obtained clinical variables that predicts numerous health outcomes. Since there are currently no tools to predict acute kidney injury (AKI) in persons with HIV (PWH), we investigated the association of preadmission VACS Index with hospital AKI in PWH.
Methods: We conducted an observational study of PWH hospitalized in a New York City health system between 2010-2019.
Compartmentalizing Donor-Acceptor Stenhouse Adducts for Structure-Property Relationship Analysis.

Department of Chemistry, Loker Hydrocarbon Research Institute, University of Southern California, Los Angeles, California 90089, United States.
The development of photoswitches that absorb low energy light is of notable interest due to the growing demand for smart materials and therapeutics necessitating benign stimuli. Donor-acceptor Stenhouse adducts (DASAs) are molecular photoswitches that respond to light in the visible to near-infrared spectrum. As a result of their modular assembly, DASAs can be modified at the donor, acceptor, triene, and backbone heteroatom molecular compartments for the tuning of optical and photoswitching properties.
