Highly Luminescent Nitrogen Doped Carbon Quantum Dots for Mercury Ion Sensing with Antibacterial Activity.

Nitrogen doped Carbon Quantum Dots (NCQDs) have been synthesized using most economical and easiest hydrothermal process. Here, N-phenyl orthophenylenediamine and citric acid were utilised as a source of nitrogen and carbon for the preparation of NCQDs. The synthesized NCQDs were characterized using experimental techniques like UV - Vis absorption, FT-IR, transmission electron microscopy (TEM), X-ray Diffraction (XRD), EDX, dynamic light scattering (DLS), fluorimeter and time resolved fluorescence spectroscopy.

Unlocking the Catalytic Potential of Anionic Micelles: Insights into the Ce(IV)-Directed Phenylalanine Oxidation Kinetics in Asymmetric Hydrophobic Environments.

The oxidation kinetics of phenylalanine (Phe) by Ce(IV) have been examined in both the absence and presence of aqueous micellar media with asymmetric tails, specifically using sodium dodecyl sulfate (SDS) and sodium tetradecyl sulfate (STS) surfactants. The reaction progress was monitored by observing a decrease in absorbance using UV-vis spectroscopy. Interestingly, the kinetic profile revealed a consistent increase in the observed rate constant values as the concentration of the surfactant increased.

Prevalence of Vitamin D Deficiency and Its Association With Anthropometric and Hematological Parameters Among Infants at a Tertiary Care Center in Meerut, India: A Cross-Sectional Study.

Introduction: Vitamin D is crucial in calcium homeostasis and bone metabolism, and its deficiency is widespread even in sun-rich regions like India. The present study sought to elucidate the prevalence of vitamin D deficiency in infants and its potential association with various anthropometric and hematological parameters.

Methods: The study was conducted in a tertiary care hospital in northern India (in 2013-14) and involved 77 nine-month-old infants.

Prospects of nano-theranostic approaches against breast and cervical cancer.

The bottleneck on therapeutics and diagnostics is removed by an alternate approach known as theranostics which combines both therapeutics and diagnostics within a single platform. Due to this "all in one" nature of theranostics, it is now extensively applied in the medicinal field mainly in cancer treatment over the conventional therapy. Recently, FDA approval of lutetium 177 (177Lu) DOTATATE and 177Lu-PSMA-based radionuclide theranostics are clinically used and very few theranostics specific to breast cancer are in clinical trials.

Ni(0)-Catalyzed Efficient, Regioselective Synthesis of Dibenzo[,]oxepines and Dibenzo[,][1,2]oxathiepine 6,6-Dioxides: Mechanistic Study by DFT Calculation and Docking Interactions.

Herein, a nickel-catalyzed divergent reductive-Heck reaction of 1-bromo-2-((2-(aryl/alkyl ethynyl)phenoxy)methyl)benzene and 2-(aryl/alkyl ethynyl)phenyl 2-bromobenzenesulfonate derivatives has been demonstrated through the regulation of reducing agents and solvent systems. This scalable protocol offers regio- and stereoselective access to functionalized dibenzo[,]oxepine and dibenzo[,][1,2]oxathiepine 6,6-dioxide scaffolds in high to excellent yields under a mild set of reaction conditions. This methodology offers a predictable route for the synthesis of medium ring oxygen heterocycles and demonstrates wide substrate scope and outstanding tolerance to various functional groups like hydroxyl and, of course, practical instance via the synthesis of doxepin and nordoxepin molecules.
