Introduction The current technique for heterotopic cardiac transplantation in patients with high pulmonary vascular resistance entails the interposition of a Dacron conduit1 between the native and donor pulmonary artery (PA) as it is not possible for the donor PA to reach the recipient PA (Figure 1). The original technique of Bernard and Losman2 was abandoned due to intractable arrhythmias. Da ...

An estimated 1-2 million people in W. Africa4 are infected with HIV-2. However, recently da Silva et al5 have reported a decline in HIV-2 prevalence in younger people probably due to lower transmission efficiency of HIV-2 compared to HIV-1 as shedding of HIV-2 in genital secretions is significantly lower. Prevalence was highest amongst women in 45-60 yrs age group probably related to hormonal c...

A simple and practical two-degree-of-freedom control strategy is proposed for unstable processes with time delay. It can decouple load disturbance from setpoint response. By combining the theory on stabilizing PID controller proposed by Silva et al. with IMC method, the process in which the ratio of time delay to unstable time constant is smaller than 2 can be controlled effectively. Simulation...

The Kinnaridae genus Potiguara was established by Hoch & Ferreira (2013) with the type species Potiguara troglobia Hoch et Ferreira, 2013 from Brazil. So far, this genus includes only the type species. Nevertheless, the name Potiguara is preoccupied and it was initially introduced by Machado et Brito, 2006 for an extinct genus of the fish family Pycnodontidae (with the type species Coelodus ros...
