Synergic effect of aqueous extracts of and on the green synthesis of silver nanoparticles and as a preventative agent against antibiotic-resistant food spoiling organisms.

The combination of and leaf water extract synergistically acts as a reducing and capping agent for the synthesis of narrow polydisperse silver nanoparticles (Ag NPs) with controlled sizes depending on the precursor (AgNO) concentration in the plant extract. The toxicity of 40 nm-sized green synthesized Ag NPs is less than that of 10 nm-sized NPs. The Ag NP solution in and leaf water extract shows synergic antibacterial effect on Gram-negative bacteria by effecting the ester group of the lipids (hydrolysis) and also breaking the amide bonds of the bacterial chemical constituents, which leads to their rapid death.

Effect of change in sequence of administration of DTwP and Hepatitis B vaccines on perception of pain in infants: A randomized control trial.

Objective: This study was designed with objective to study pain response of infants to change in sequence of administration of Hepatitis B and DTwP vaccines.

Methods: This was a randomized parallel control trial. The study was carried out in the immunization clinic of the Department of Pediatrics, LLRM Medical College, Meerut.

A repertory grid comparison of endogenous and neurotic depressions.

The Repertory Grid Technique was used to study the construct systems of patients diagnosed as Endogenous and Neurotic Depressions. Twenty-five patients of each category were administered a Rank Order Repertory Grid comprising ten elements and fifteen constructs. The completed matrices were subjected to principal component analysis.
