Expectancy or Salience?-Replicating Senders' Dial-Monitoring Experiments With a Gaze-Contingent Window.

Introduction: In the 1950s and 1960s, John Senders carried out a number of influential experiments on the monitoring of multidegree-of-freedom systems. In these experiments, participants were tasked with detecting events (threshold crossings) for multiple dials, each presenting a signal with different bandwidth. Senders' analyses showed a nearly linear relationship between signal bandwidth and the amount of attention paid to the dial, and he argued that humans sample according to bandwidth, in line with the Nyquist-Shannon sampling theorem.

Banking of osteochondral allografts, Part II. Preservation of Chondrocyte Viability During Long-Term Storage.

One of the most important factors concerning the successful clinical outcome after transplantation of osteochondral allografts is the viability of the cartilage.The viability of cryopreserved cartilage is quite poor, 20-30% cell survival has been published. The purpose of this study was to develop a new storage method which improves the chondrocyte viability.

Banking of osteochondral allografts. Part I. Viability assays adapted for osteochondrol and cartilage studies.

The aim of this study was to adapt a reliable, reproducible and simple viability assay for cartilage and osteochondral studies. The previous assays (radioisotope uptake, assessment of matrix components, histological methods, oxygen consumption etc.) were complex, laborious, time consuming or suffer from difficulty of interpretation.

Osteochondral resurfacing of the knee joint with allograft. Clinical analysis of 33 cases.

This retrospective clinical study describes three years of experience with cryoprotected-cryopreserved allograft transplantation. During this period 33 knee joints were operated on for different reasons including osteoarthritis, osteochondritis dissecans and post-traumatic surface irregularity. The mean follow-up was nearly two years and the mean age of the patients was 48 years.
