Nitric oxide-mediated regulation of macronutrients in plants.

In plant physiology, nitric oxide (NO) is a widely used signaling molecule. It is a free radical and an important component of the N-cycle. NO is produced endogenously inside plant cells, where it participates in multiple functions and provides protection against several abiotic and biotic stresses.

Micronutrient deficiency-induced oxidative stress in plants.

Micronutrients like iron (Fe), zinc (Zn), copper (Cu), manganese (Mn), boron (B), nickel (Ni), and molybdenum (Mo) perform significant roles in the regulation of plant metabolism, growth, and development. Micronutrients, namely Fe, Zn, Cu, Mn, and Ni, are involved in oxidative stress and antioxidant defense as they are cofactors or activators of various antioxidant enzymes, viz., superoxide dismutase (Fe, Cu/Zn, Mn, and Ni), catalase (Fe), and ascorbate peroxidase (Fe).

Awareness and Safety of COVID-19 Vaccination in Pregnancy.

Background: COVID-19 vaccines are safe in pregnancy, as they do not contain a live attenuated virus. Mass vaccination is a key to control the pandemic. Neonates have been shown to be susceptible to severe illness, so maternal vaccination is important to provide neonatal vaccination.
