The effects of oral oxprenolol (480 mg) and lorazepam (2 mg) on skin conductance, reaction time, critical flicker frequency and self-rating visual analogue scales for anxiety, sedation and concentration were investigated in 6 healthy male volunteers. Oxprenolol exerted a central action similar to lorazepam as shown by a significant lowering of skin(More)
BACKGROUND The double-bundle technique has recently gained much interest in ligament reconstruction. In addition to potential kinematic advantages, perhaps double tunnels have the potential for faster and more secure tendon-to-bone healing. HYPOTHESIS Placement of tendons in 2 osseous tunnels, as opposed to 1, will enhance tendon fixation as determined(More)
A review of 179 autopsies was undertaken over a 1-year period to determine if clinically useful information was obtainable from coroners post mortems performed on patients referred from the A&E department. Fifty-six patients had undergone unsuccessful resuscitation. The leading causes of death were heart disease and trauma. Discrepancies between the(More)
This article reviews basic concepts in fundamental elbow biomechanics, particularly how they relate to the skeletally immature elbow in throwing athletes. Adult phases of throwing and the forces generated in each phase are compared with the developmental phases of throwing in children. The impact of elevated forces, poor mechanics, and poor coordination are(More)
Requirements to control the large decrease in serum calcium (Ca) due to parturition and to increase the feed intake soon after parturition have been well accepted in dairy cows. This study was aimed to investigate the feed intake affected by serum Ca concentration with difructose anhydride (DFA) III supplement in dairy cows soon after parturition. Fourteen(More)
The incidence of hypocalcemia increases in high-parity dairy cows because resorption of bone Ca is delayed in these animals, and they appear to have a reduced ability to absorb Ca from the intestine during the early postpartum period. Difructose anhydride (DFA) III has been shown to promote the absorption of intestinal Ca via a paracellular pathway.(More)
PURPOSE The purpose of this study was to quantify the changes in the arc of digital flexion before and after metacarpophalangeal (MCP) silicone arthroplasty with a 30 degrees preflexed design. METHODS Index, middle, and ring fingers of 4 fresh-frozen cadaver hands were used. Each hand was attached (palmar side up) to a custom test apparatus. The tendon(More)
