Smartphone-Assisted EY@MOF-5-Based Dual-Emission Fluorescent Sensor for Rapid On-Site Detection of Daclatasvir and Nitenpyram.

Fluorescent metal-organic frameworks (MOFs) are promising sensing materials with tunable and robust structural properties and remarkable luminescent capabilities. In this study, a novel dual-emission fluorescent metal-organic framework (EY@MOF-5) composite is synthesized by a one-pot bottle-around-ship approach. Eosin Y (EY) is encapsulated in MOF-5 to enhance its fluorescence properties and selectivity, effectively addressing typical MOF-5 limitations.

Methods for detection and quantification of gelatin from different sources.

Gelatin is a water-soluble protein obtained from the collagen of various animal origins (porcine, bovine, fish, donkey, horse, and deer hide) and has diverse applications in the food, pharmaceutical, and cosmetics industries. Porcine and bovine gelatins are extensively used in food and non-food products; however, their acceptance is limited due to religious prohibitions, whereas fish gelatin is accepted in all religions. In Southeast Asia, especially in China, gelatin obtained from donkey and deer skins is used in medicines.

Calciphylaxis in a Biopsy of Pyoderma Gangrenosum in a Patient Without End-Stage Kidney Disease.

Calciphylaxis is a rare condition characterized by calcification of the blood vessels in the subcutaneous tissue with tissue ischemia. Calcium deposition is observed within scarred and occluded blood vessels of the subcutaneous tissue when a biopsy of the lesion is performed. Calciphylaxis is usually associated with end-stage kidney disease.
