[¹³N] Ammonia Positron Emission Tomographic/Computed Tomographic Imaging Targeting Glutamine Synthetase Expression in Prostate Cancer

Xinchong Shi, Xiangsong Zhang, Chang Yi, Yubo Liu, and Qiao He   Abstract The purpose of this study was to investigate the expression of glutamine synthetase (GS) in prostate cancer (PCa) and the utility of [¹³N]ammonia positron emission tomography/computed tomography (PET/CT) in the imaging of PCa. The uptake ratio of [¹³N]ammonia and the expression of […]

Dairy products, calcium, and prostate cancer risk in the Physicians’ Health Study

Dairy products, calcium, and prostate cancer risk in the Physicians’ Health Study June M Chan, Meir J Stampfer, Jing Ma, Peter H Gann, J Michael Gaziano, and Edward L Giovannucci ABSTRACT Background: A high calcium intake, mainly from dairy products, may increase prostate cancer risk by lowering concentrations of 1,25-dihydroxyvitamin D3 [1,25(OH)2D3], a hormone thought […]
