A simplified method for the determination of nitric oxide in biological solutions.

abstract：AIMS:Obesity is a complex health disorder and a trigger to many diseases like Diabetes mellitus (DM) and breast cancer (BrCa), both leading causes of morbidity and mortality worldwide. Also evidence demonstrates that abnormal glucose metabolism termed 'the Warburg effect' in cancer cell is closely associated with malig...
