Spatial distribution of fossil fuel derived CO2 over India using radiocarbon measurements in crop plants

Examining the contribution of fossil fuel CO₂to the total CO₂changes in the atmosphere is of primary concern due to its alarming levels of fossil fuel emissions over the globe,specifi cally developing countries.Atmospheric radiocarbon represents an important observationa constraint and utilized to trace fossil fuel derived CO₂(CO_2ff) in the atmosphere.For the firs time,we have presented a detailed analysis on the spatial distribution of fossil fuel der...     

Therapeutic applications of resveratrol nanoformulations

Resveratrol, or 3, 5, 4-trihydroxy-trans-stilbene, is a naturally occurring polyphenol present in several dietary sources such as grapes, soybeans, berries, pomegranate and peanuts. Resveratrol has received recent attention due to its diverse pharmacological activities. However, resveratrol clinical efficacy is limited due to its poor systemic bioavailability, of less than 1%, which is due to its low aqueous solubility, extensive first-pass metabolism and existence of enterohepatic recirculation. Therefore, in order to overcome these limitations, various nanocarriers including polymeric nanoparticles, solid lipid nanoparticles, liposomes, micelles and conjugates have been developed. These nanocarriers are able to enhance the bioavailability of resveratrol by modulating the P-glycoprotein, cytochrome P-450 enzymes and bypassing the hepatic first-pass effect. Here we review resveratrol nanoformulations for enhancing the efficacy of native resveratrol.
