Herein, we demonstrate a novel strategy to tailoring and stabilizing the active sites interface on hierarchical three-dimensional (3-D) iron-cobalt phosphides Fe1-xCoxP nanosheets on nickel oxide nanoparticles for overall water splitting....
Microbial community has been a major part in the drug industry. They are known for their effectiveness and do not cause any undesirable effects. Exploitation of bacteria could be fruitful for mankind. Bacteria play a major role in producing useful bioactive compounds. HSV-1 infection causes 80% of oral lesions. A majority of the population is infected by at least one herpes subtype of HSV-1 before adulthood. The infection in some cases does not produce any symptoms. Drugs for HSV-1 are becoming suppressive. In the present study, isolation of endophytic bacteria was carried out from medicinal plant. A grown bacterium was identified and confirmed using molecular 16S rRNA sequencing followed by extraction of bioactive compounds using solvents. Twelve bioactive compounds were then investigated for in vitro cytotoxicity assay and in vitro antiviral assay. Chloroform extract was found to be effective in inhibiting the virus.
Tomato is adapted to a wide range of climatic conditions but most sensitive to water stress, especially at the flowering stage, causing drastic yield reduction. In the present study, a pot culture experiment was conducted to evaluate the efficacy of naphthalene acetic acid (NAA) and salicylic acid (SA) nanoformulations against drought effects in tomato during flowering stage. The drought was imposed at 50% flowering by withholding irrigation, and foliar application of nanoformulations was given when the reduction in soil moisture reaches 20 percent. The treatments include NAA (20 & 40 ppm), salicylic acid (50 & 100 ppm), and NAA (20 ppm) + salicylic acid (50 ppm) as straight and nanoformulations along with a control. Observations done on first, second and third day after foliar application revealed a significant increase in chlorophyll index, relative water content, membrane stability index, and chlorophyll stability index due to the application of nanoformulation of NAA + salicylic acid in the plants under drought. The results indicated the efficacy of nanoformulation of NAA + salicylic acid in ameliorating the deteriorative effects of drought in tomato by improving the physiological traits compared to the application of the NAA and salicylic acid as straight formulations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
