Identifying potentially avoidable femoral to popliteal expanded polytetrafluoroethylene bypass for claudication using cross-site blinded peer review.

Objective: The surgical treatment of claudication can be associated with significant morbidity and costs. There are growing concerns that some patients proceed to interventions without first attempting evidence-based nonoperative management. We used a direct, cross-site, blinded expert review to evaluate the appropriateness of the surgical treatment of claudication.

Hand path priming in manual obstacle avoidance: evidence for abstract spatiotemporal forms in human motor control.

Previous research suggests that motor equivalence is achieved through reliance on effector-independent spatiotemporal forms. Here the authors report a series of experiments investigating the role of such forms in the production of movement sequences. Participants were asked to complete series of arm movements in time with a metronome and, on some trials, with an obstacle between 1 or more of the target pairs.

Calcium channel antagonists and adenosine analogues decrease tolerance to opiate pentazocine and U 50488H.

1. A single dose of pentazocine induces cross-tolerance the analgesic effects of the kappa agonist U 50488H. Tolerance is observed by means of the hot plate test or by the i.

Morphological changes on nerves and histopathological effects on liver and kidney of rats by pentachlorophenol (PCP).

1. The chronic toxicity of pentachlorophenol (PCP) was studied in rats after 90-120 days of oral administration ad libitum of 0.3-3 mM PCP aqueous solutions.
