Results from recent studies investigating the dynamics of bimanual coordination have led to contrasting viewpoints concerning the relative contribution of perceptual and motor processes in mediating coordinative stability. At one end of the spectrum is the belief that coordination is governed primarily by physical limitations such as neuro-muscular constraints and that perceptual factors play l...

The receptor tyrosine phosphatases DPTP69D and DPTP99A are expressed on motor axons in Drosophila embryos. In mutant embryos lacking DPTP69D protein, motor neuron growth cones stop growing before reaching their muscle targets, or follow incorrect pathways that bypass these muscles. Mutant embryos lacking DPTP99A are indistinguishable from wild type. Motor axon defects in dptp69D dptp99A double ...

Sugammadex sodium is a modified γ-cyclodextrin with a very high affinity for rocuronium and, to a lesser extent, vecuronium molecules. In vivo administration results in immediate encapsulation of rocuronium and vecuronium, resulting in termination of neuro- muscular blockade, usually within 3 minutes. This new neuromuscular blocking agent is specific for the aminosteroidal neuromuscular blockin...

This paper reviews a nonlinear complexity within the Human Biodynamics Engine (HBE), a world-class human neuro-musculoskeletal simulator, developed at the Department of Defense, Australia. The HBE development is based on an anthropomorphic tree of Euclidean motion groups SE(3), with 270 active degrees of freedom, realistic muscular mechanics and hierarchical neural-like control. The HBE is form...

Experiments were carried out on the isolated phrenic nerve diaphragm preparation of the rat and isolated sartorius nerve muscle preparations of the frog (Rana tigrina), for the comparison of the neuro-muscular blocking activity. The preparations were set up in 100 ml organ bath containing Tyrode solution at 37°C for rat diaphragm and at room temperature for the frog muscle preparation. The solu...

We present and compare two delayed random walk models of neural information processing. A delayed random walk is a random walk in which the transition probability depends on the position of the walker at a time in the past. The rst model is of human neuro-muscular control for postural sway. The other model is for a stochastic single neuron which has a delayed self{exciting feedback. We study ea...

4Reader, Department of Periodontics, JCD Dental College Sirsa, Haryana, India. ABSTRACT The goal of any prosthetic procedure must include the establishment of a functional occlusion. It is known that natural teeth have periodontal ligament receptors that protect the teeth from excessive occlusal forces, which can cause trauma to supporting tissues and bone. Although many factors are involved in...

The prelude to a training in operative surgery is intensive exposure to many disciplines. A working knowledge of anatomy, and especially visceral anatomy as opposed to the skeletal and neuro-muscular anatomy of the text books, is essential. This knowledge will receive further refinement later in the operating room, the final school of practical anatomy. An awareness of the pathology of the lesi...

OHS is also known as Pickwickian syndrome, named for a character—a “fat boy” who is constantly falling asleep—in The Posthumous Papers of the Pickwick Club by Charles Dickens. Salient features of OHS are: Obesity (body mass index ≥ 30 kg/m • 2) Sleep-disordered breathing (most patients with • OHS are morbidly obese and have severe obstructive sleep apnea1) Chronic daytime alveolar hypoventilati...
