Pleurotus Ostreatus Copper Nanoparticles: In Vitro and In Silico Evaluation of the Antioxidant, Antibacterial and Antidiabetic Activities.

The rapid growth of nanotechnology has opened new frontiers in biomedical applications, particularly through the use of metal nanoparticles. This study explores the green synthesis of copper nanoparticles (CuNPs) using an aqueous extract of Pleurotus ostreatus (PO-CuNPs), and their characterization through UV-visible spectroscopy, FTIR, SEM, and EDAX. The synthesized PO-CuNPs demonstrated exceptional antioxidant activity, evident in hydrogen peroxide scavenging and phosphomolybdenum assays.

Computational investigation of NO emission in biogas combustion.

Landfills and anaerobic digesters in the waste treatment processes generate biogas. Biogas can be used as a fuel and excess biogas is typically burned in a flare to reduce the greenhouse effect. However, burning biogas produces several pollutants, including CO, NO, and SO.

Utility of Indigenous Cytology Technique in the Diagnosis of Oral Cavity Lesions using Normal Saline as a Processing Fluid: A Comparative Study.

Background: Oral cancer is a major health problem in developing countries. Cytology has been widely accepted as a tool in the early diagnosis of cancer.

Objectives: To evaluate the diagnostic utility of four different cytology techniques, that is, modified brush cytology (BR) technique, brush cytology cytocentrifugation (BRCC) technique, modified scrape cytology (SR) technique, and scrape cytology cytocentrifugation (SRCC) technique and correlate the cytopathological diagnosis with the available histopathological diagnosis.
