Pyrogallol-based dipodal optical probe as new smart analytical tool for sustainable detection of cobalt in biosystem.

The present research focuses on the micro-level detection of cobalt ions in biological and environmental samples using a new probe. The probe is a multifunctional symmetrical dipodal molecule with two pyrogallol binding units attached to the malonate scaffold through a propylene spacer. It was synthesized and characterized by H NMR, C NMR, IR, electronic spectroscopy, and mass spectrometry.

Determination of causes of adult deaths using minimally invasive tissue sampling in Gandaki province of Nepal: a multicenter hospital-based study.

Background: Minimally Invasive Tissue Sampling (MITS) has been successfully used to establish the cause of death in low- and middle-income countries, mostly in stillbirths and neonates. The objective of this study was to determine the causes of death among adults using MITS in the Gandaki province of Nepal and to find out the contribution of MITS to identify the causes of death.

Methods: A multicentric hospital-based pilot study was conducted to enroll 100 cases of adult deaths.

The Ominous Aspergillus With Cancer of Blood Vessels: A Case of Invasive Aspergillosis and Epithelioid Angiosarcoma of the Lung.

Invasive aspergillosis occurs in the setting of risk factors such as severe or prolonged neutropenia, defects in cell-mediated immunity, and receipt of immunosuppressive therapy, particularly in patients with graft-versus-host disease (GVHD). Pulmonary epithelioid angiosarcomas (EASs) are rare malignant vascular tumors that are aggressive, frequently metastatic, and associated with a poor prognosis. We describe these two rare conditions occurring concurrently.

Effect of altitude and solvent on Psidium guajava Linn. leaves extracts: phytochemical analysis, antioxidant, cytotoxicity and antimicrobial activity against food spoilage microbes.

Background: Guava (Psidium guajava Linn.) has been traditionally used in the treatment of a wide range of diseases due to its rich content of secondary metabolites.

Aim: This study was aimed to evaluate the effect of altitude and solvent systems on guava leaves crude extract's phenolics and flavonoid content, antioxidant, antimicrobial, and toxicity nature.

Schiff Bases: A Versatile Fluorescence Probe in Sensing Cations.

Metal cations such as Zn, Al, Hg, Cd, Sn, Fe, Fe and Cu play important roles in biology, medicine, and the environment. However, when these are not maintained in proper concentration, they can be lethal to life. Therefore, selective sensing of metal cations is of great importance in understanding various metabolic processes, disease diagnosis, checking the purity of environmental samples, and detecting toxic analytes.
