Waste-Derived Copper Flakes for Solvent-Free Reductive Acetamidation of Nitroarenes.

Herein, waste-derived copper (Cu) flakes have been used as heterogeneous catalysts for the solvent-free and one-pot reductive acetamidation of nitroarenes. Metallic copper flakes (f-ZCu) were isolated from waste copper Cu scrap/flakes/turnings generated after the grinding and cutting (from the Cu industries). f-ZCu is being used to synthesize acetanilide with a considerable yield (∼82%) in one-step and solvent-free conditions within a reaction time of 6 h.

Comparative Dynamic Pulmonary Function Tests Between Apparently Healthy Young Adult Offspring of Asthmatic and Non-asthmatic Parents: A Pilot Study.

Background While the hereditary component of asthma has been established, its influence on early respiratory function changes in otherwise healthy offspring remains to be explored. Dynamic lung function tests assess airflow in and out of the lungs, providing valuable insights into respiratory health and detecting potential airflow limitations. This study aimed to compare the dynamic lung functions between offspring of asthmatic and non-asthmatic parents.

Seed priming with brassinolides improves growth and reinforces antioxidative defenses under normal and heat stress conditions in seedlings of Brassica juncea.

Environmental stresses pose a major challenge for plant researchers to fulfill increasing food demand. Researchers are trying to generate high-yielding and stress-tolerant or resistant varieties using classical genetics and modern gene-editing tools; however, both approaches have limitations. Chemical treatments emerged as an alternative to improve yield and impart stress resilience.

Migratory behaviour of Brown planthopper, (Stål) (Hemiptera: Delphacidae), in India as inferred from genetic diversity and reverse trajectory analysis.

Unlabelled: The brown planthopper, (Stål) is a major sucking insect pest of rice. This insect has long been considered as migratory; however, its route in India is still unknown. Hence, to find out its migration route genetic diversity, genetic structure and gene flow of 16  populations from major rice growing regions of India was studied based on mitochondrial cytochrome oxidase I (COI).

Analytical performances of different diagnostic methods for SARS-CoV-2 virus - A review.

Covid-19 is a dreadful pandemic of the 21st century that has created fear among people, affected the whole world, and taken thousands of lives. It infects the respiratory system and causes flu-type symptoms. According to the WHO reports, 2,082,745 deaths and 96,267,473 confirmed cases were perceived all around the globe till January 22, 2021.

DNA barcoding and Taxonomic account on some selected species of subfamily Plusiinae (Lepidoptera: Noctuidae) from India.

This study represents a detailed taxonomic account of 31 species of Plusiinae (Lepidoptera: Noctuidae) from India. The survey and collection of 39 localities from different regions of India between 2015 and 2018. The tribe Argyrogrammatini Eichlin Cunningham, 1978 with Ctenoplusia Dufey, 1970 was the most species rich genera with seven species, followed by Thysanoplusia Ichinose, 1973 and Chrysodeixis Hubner, 1821 with four and three species respectively.

Genetic homogeneity in South American tomato pinworm, : a new invasive pest to oriental region.

South American tomato leaf miner, (Meyrick, 1917) (Lepidoptera: Gelechiidae), is an important invasive pest of Tomato which invaded India and Nepal in 2014 and 2016, respectively. In the present study, samples from five localities of India and one from Nepal were used for the investigation of genetic diversity of by employing a fragment in the mtDNA gene-encoding cytochrome oxidase I (COI). Based on the partial COI gene, high genetic homogeneity was detected in populations of India and Nepal with rest of the world.

Vibrational spectra and first order hyperpolarizability studies of dimethyl amino pyridinium 4-nitrophenolate 4-nitrophenol.

Vibrational spectra of the organic nonlinear optical crystallized dimethyl amino pyridinium 4-nitrophenolate 4-nitrophenol have been recorded and analyzed. The spectral interpretation has been done based on the density functional theory using the standard B3LYP/LANL2DZ basis set. Total energy distribution is calculated using the scaled quantum mechanic program.

Cell death does not herald epithelial involution ("atrophy") in oral sub mucous fibrosis: a TEM study.

The disease progression in oral submucous fibrosis (OSF) seems to be in a biphasic manner, along both fibroblastic and keratinocytic lineages. The epithelial malignancy is considered to be a sequel of connective tissue changes. "Atrophy" of epithelium makes it amenable to the effect of oral carcinogens.
