Frequency and characteristics of gnathic dense bone islands in a paediatric population residing in Chandigarh, India: a cross-sectional radiographic study.

Aim: To determine the frequency and characteristics of Dense Bone Islands (DBIs) in a paediatric population residing in Chandigarh, India.

Methodology: A total of 3614 orthopantomographs (OPG) of children between the age group of 6-18 years were collected from the database of patients who underwent panoramic radiography for routine dental treatment during the period of 2018-2020. The shape, location of the lesion, and relationship of the Dense Bone Island with the tooth were identified.

Assessment of soil microbial diversity and soil enzyme activities under inorganic input sources on maize and rice ecosystems.

Background: To increase crop productivity, modern agricultural practices comprises fertilizers, algaecides, herbicides and fungicides.

Objective: The purpose of this study was to evaluate the effects of soil microbial population and soil enzyme activity by the use of fertilizer in maize and inorganic input in the rice ecosystem.

Methods: A field experiment (2021 to 2023) was carried out using synthetic fertilizer doses with maize crops followed by rice crops using inorganic inputs.

Elucidating the structural, anticancer, and antibacterial traits of Punica granatum peel extracts-mediated Ag and Ag/GO nanocomposites.

Ag nanoparticles and Ag/GO nanocomposites have been synthesized by facile, eco-friendly, and cost-effective green approach using the peel extracts of Punica granatum. The synthesized Silver Nanoparticles and Silver Graphene Oxide nanocomposites were characterized by UV-visible spectroscopy, X-ray diffraction, transmission electron microscopy, and Fourier transform infrared analysis. AgNPs revealed spherical morphology with particle size ranging from 30 to 40 nm.

Clinico-pathological features in fatal COVID-19 infection: a preliminary experience of a tertiary care center in North India using postmortem minimally invasive tissue sampling.

Objectives: To study the histopathology of patients dying of COVID-19 using post-mortem minimally invasive sampling techniques.

Methods: This was a single-center observational study conducted at JPNATC, AIIMS. Thirty-seven patients who died of COVID-19 were enrolled.

Exploring the influence of varying pH on structural, electro-optical, magnetic and photo-Fenton properties of mesoporous ZnFeO nanocrystals.

An economically viable and superficial technique was indorsed to yield ZnFeO nanocrystals in the system to investigate the impact of pH variation on the optical, structural, electrical, and magnetic properties of as-prepared nanocrystals. The as-synthesized ZnFeO nanocrystals were premeditated with the application protracted to degradation of Methylene blue organic dye. The results specify that the pH plays the utmost decisive facet in photo-Fenton recital.
