Owing to the critical role of ascorbic acid (vitamin C, VC) in human bio-activities as an antioxidant and free radical scavenger, the development for an easy and fast VC detection has always been pushed. In this work, a traditional ligand bipyridine (bpy) was firstly oxidized (denoted as bpy-O) and then coordinated to Eu(III) (denoted as Eu-bpy-O). Due to the oxidization of bpy N atoms, which led to improper triplet ligand energy level and increased ligand-to-Eu distance, the efficient ligand energy transfer (ET) to Eu(III) was suspended, resulting in a low emission quantum yield of 1...

<b/>The effect of green tea administration on serum lipids' concentrations remains unclear as various investigations, which have explored this topic, have produced conflicting results. Gender might be one of the factors influencing the impact of green tea on the lipid profile. Hence, we conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) to assess the effect of green tea intake on the lipid profile in overweight and obese women. We searched five databases (Web of Science, SCOPUS, Embase, PubMed/Medline, and Google Scholar) using a combination of MeSH and non-MeSH terms...

The optimal spray-drying conditions for manufacturing Japanese apricot ( Prunus mume Sieb. et Zucc.) juice powder (JAJP) using response surface methodology (RSM) were investigated. The optimization was performed using two independent factors, which are inlet air temperature (130-180 °C) and different concentrations of nondigestible maltodextrin (NMD) as a carrier agent (10-30%). Responses such as drying yield, moisture content, water solubility index (WSI), bulk density, color, pH, and antioxidant activities of JAJP were investigated...

Vitamin K is a vital micronutrient implicated in a variety of human diseases. Warfarin, a vitamin K antagonist, is the most commonly prescribed oral anticoagulant. Patients overdosed on warfarin can be rescued by administering high doses of vitamin K because of the existence of a warfarin-resistant vitamin K reductase. Despite the functional discovery of vitamin K reductase over eight decades ago, its identity remained elusive. Here, we report the identification of warfarin-resistant vitamin K reductase using a genome-wide CRISPR-Cas9 knockout screen with a vitamin K-dependent apoptotic reporter cell line...
