Gold Nanoparticles: A new approach for cancer detection

Gold nanoparticles are produced in a liquid ("liquid chemical methods") by reduction of chloroauric acid (H[AuCl4]), although more advanced and precise methods do exist. Gold nanoparticles are also found to distinguish between cancer cells and noncancerous cells. Another benefit is that the results are instantaneous. “If you take cells from a cancer stricken tissue and spray them with these gold nanoparticles that have this antibody you can see the results immediately. The scattering is so strong that you can detect a single particle. The interaction between light and gold nanostructures is not only useful for the treatment of cancer but also for its diagnosis.

Phytochemical investigation of the roots ofGrewia microcosLinn.

Image
ABSTRACT: The present study reports the phytochemical investigation of the roots of Grewia microcos linn. Seven Phytoconstituents have been reported namely 9,12- octadecadienoic acid; Ursolic acid; Stigmasterol; 6,4- dihydroxy-3-propen chalcone; Dioctyl phthalate; N-methyl-6-β-(1’,3’,5’-trienyl)-3-β-methoxyl-3-β-methyl piperidine; and Dibutyl phthalate have been reported for the first time from the roots of Grewia microcos.

A Validated specific Stability-indicating RP-HPLC method for Aripiprazole and its related substances

Image
ABSTRACT : A validated specific stability indicating reversed-phase liquid chromatographic method was developed for the quantitative determination of Aripiprazole and its related substances in bulk samples, pharmaceutical dosage forms in presence of degradation products. Forced degradation studies were performed on bulk sample of Aripiprazole as per ICH prescribed stress conditions using acid, base, oxidative, thermal stress and photolytic degradation to show the stability indicating power of the method. Significant degradation was observed during basic stress and no degradation was observed in other stress conditions. The chromatographic method was optimized using the samples generated from forced degradation studies and the impurity spiked with Aripiprazole. Good resolution between the peaks corresponds to impuritiy-1, degradation products from the analyte were achieved on YMC PACK C18 column using the mobile phase consists a mixture of Sodium dihydrogen Orthophosphate dehydra...
