Background: Insulin increases endothelial nitric oxide (NO) production by activating endothelial nitric oxide synthase (eNOS) through protein kinase B (Akt)-mediated phosphorylation of serine residue 1179 (p-eNOS serine 1179). Because fatty acids modulate insulin-stimulated Akt signaling cascades in smooth muscle cells, we hypothesized that fatty acids would differentially regulate endothelial ...

The authors tested whether a simple model based on the cancellation of the rate of change in bearing angle could account for the behavioral adaptations produced when individuals intercept moving balls while walking. In Experiment 1, the place of arrival of the ball and the angle of approach were varied. In accord with the model, velocity regulations were earlier and more pronounced the larger t...

In my opening remarks the acoustics and signal processing involved in active control will be reviewed: both for enhancing audio signals and for attenuating acoustic noise. The physical limits due to the geometry of practical arrays will be discussed, together with the signal processing design methods that can be used to implement robust practical arrays, whose performance approaches these geome...

In this paper a Kalman filter is used to cancel noise and interference contained in two accelerometers embedded in a car under performance tests. Here, the frequency bands of the signals of interest and their noise (deterministic as well as stochastic) are not strongly mixed with each other but it is very difficult to diminish the noise by using the classical approach to filtering. This reason,...

Introduction: Esophagus injuries secondary to caustic ingestion occurs frequently in children. Oral damages cannot give us a clear image of what has happened in upper GI. Therefore endoscopy is only diagnostic way to evaluate upper GI injuries. In this study, we found out the endoscopic results in children admitted with caustic ingestion in Qaem(A. S.) hospital between 2011 to 2013 , and comp...
