End-stage vascular access failure: can we define and can we classify?
BACKGROUND Renal replacement therapy using dialysis has evolved dramatically over recent years with an improvement in patient survival. With this increased longevity, a cohort of patients are in the precarious position of having exhausted the standard routes of vascular access. The extent of this problem of failed access or 'desperate measures' access is difficult to determine, as there are no ...
متن کاملModulating multidrug resistance: can we target this therapy?
The Multidrug Resistant Phenotype The MDR phenotype was developed by exposing cells to very high concentrations of cytotoxic agents in vitro (1). The best understood mechanism of resistance in MDR is the increased expression of P-gp, a transmembrane energy-dependent drug efflux pump, which is most efficient at transporting natural occurring substances such as the anthracyclines, Vinca alkaloids...
متن کاملCan We Define Levels Of Artificial Intelligence?
The paper argues for a graded approach to the study of artificial intelligence. In contrast to the Turing test approach, such an approach permits the measurement of incremental progress in AI research. Results on the conceptual abilities of pigeons are summarized. These abilities far exceed the generalization abilities of current AI programs. It is argued that matching the conceptual abilities ...
متن کاملHow can we define intrinsic motivation?∗
Intrinsic motivation is a crucial mechanism for open-ended cognitive development since it is the driver of spontaneous exploration and curiosity. Yet, it has so far only been conceptualized in ad hoc manners in the epigenetic robotics community. After reviewing different approaches to intrinsic motivation in psychology, this paper presents a unified definition of intrinsic motivation, based on ...
متن کاملFrequency-response characteristics of vascular resistance vessels.
ROSENBAUM, ‘MAURICE, AND DAVID RACE. Frequency-response characteristics of nascdar resistance vessek Am. J. Physiol. 215(6) : 1397-1402. 1968.-The dynamic response of the hindlimb resistance vessels to sympathetic stimulation was studied in 16 dogs, using step and sinusoidally modulated stimuli. The system is nonlinear and the form of the rise in resistance differs from that of the fall. A step...
