Port Coquitlam, Vc M, H. D. Taghirad, P. R. Belanger, A. Helmy

Despite widespread industrial application of harmonic drives, modelling and control of such systems has not been fully addressed. In this theoretical/experimental study of harmonic drive systems a...

Enhanced vasodilatation to endothelin antagonism in patients with compensated cirrhosis and the role of nitric oxide

Helmy, A, Newby, D E, Jalan, R, Hayes, P C, Webb, D J

Background and aims: Patients with advanced cirrhosis have systemic vasodilatation and increased nitric oxide (NO) production despite activated vasopressor systems, including the endothelin system....

Randomised controlled trial of long term portographic follow up versus variceal band ligation following transjugular intrahepatic portosystemic stent shunt for preventing oesophageal variceal rebleeding

Tripathi, D, Lui, H F, Helmy, A, Dabos, K, Forrest, E, Stanley, A J, ...

Background/aims: Transjugular intrahepatic portosystemic stent shunt (TIPSS) is effective in the prevention of variceal rebleeding but requires invasive portographic follow up. This randomised...
