An analysis of availability and implications of unlabeled retracted articles on Sci-Hub.

Background: Researchers are increasingly accessing scientific articles through unauthorized websites like Sci-Hub. Sci-Hub contains retracted articles, including those which are not labelled as retracted, and this is a potential threat to academic research.

Methods: This study analyses the extent of the availability of retracted articles within the Sci-Hub, particularly focusing on the presence of unlabeled retracted articles (URA) which may inadvertently be used in subsequent research, thus propagating flawed findings.

Microwave-assisted synthesis of base-modified fluorescent 1,4-dihydropyridine nucleosides: photophysical characterization and insights.

A synthesis of a small library of fluorescent 1,4-dihydropyridine nucleoside analogues has been successfully carried out under solvent-free conditions a one-pot three-component Hantzsch condensation reaction. The process involved a Ba(NO) catalyzed solvent-free reaction between 3',5'-di--acetyl-5-formyl-2'-deoxyuridine, differently substituted β-keto ester and ammonium acetate under microwave irradiation. This facile methodology yielded the desired products with very high yields (86-96%) under solvent-free reaction conditions in a short reaction time, which was followed by a simple workup.

Our investigation focused on understanding the structure-antioxidant property relationship.

The Diversity of Forensic Entomofauna Associated With Decaying Chicken Liver in the Tropical Region of Kerala, India.

Forensic entomology To elucidate the time of death based on insect evidence, there are several studies on forensic entomology on life cycles, environmental factors, and feeding habitats of insects. However, there have not been any comprehensive studies on forensic entomology and its usage in forensic inquiry specific to the region, especially Kerala, India.
