Nelumbo nucifera Gaertn is a recognised herbal plant in ancient medical sciences. Each portion of the plant leaf, flower, seed and rhizome is utilised for nutritional and medicinal purposes. The chemical compositions like phenol, alkaloids, glycoside, terpenoids and steroids have been isolated.

Psychological Distress and Coping Among Dental Practitioners During the COVID-19 Pandemic: A Survey From India.

Aim: Most dental procedures are aerosol-generating and hence highly risky for spreading SARS-CoV-2 (COVID-19) infection. This can lead to sufficient psychological distress, avoidance of risky procedures, and impact on dental practice. We intend to examine the effect of the COVID-19 pandemic on dental practice and psychological distress among dental practitioners.

Enhanced reactivity and selectivity of asymmetric oxa-Michael addition of 2'-hydroxychalcones in carbon confined spaces.

Carbon nanotubes (CNTs) are employed as nanoscale reaction vessels for the asymmetric oxa-Michael addition of 2'-hydroxychalcones. A systematic comparison of the catalytic activities of chiral phosphoric acid treated ferrite nanoparticles (chiral ferrites) has been studied for the synthesis of flavanones. Higher reactivity and selectivity with switching of enantiomers were observed when these chiral ferrites are inside the CNT channel.
