To test the hypothesis that dobutamine-induced myocardial ischemia causes early-systolic asynchrony predominantly in the regional left ventricular wall, color kinesis (CK) images during dobutamine stress echocardiography (DSE) were recorded in 13 patients with coronary artery disease and in 10 patients without, all of whom showed normal wall motion at rest. Based on the visual interpretation of...

Takotsubo cardiomyopathy (TTC) is characterized by transient regional systolic dysfunction of the left ventricle in the absence of angiographic evidence of obstructive coronary artery disease or acute plaque rupture. In most cases of takotsubo cardiomyopathy, the regional wall motion abnormality extends beyond the area perfused by a single epicardial coronary artery. It mimics acute coronary sy...

An algorithm for animal searching behaviour was constructed that allows independent variation at random of movement parameters such as speed, duration, step size, and maximum right or left turn angle. The area, radius of the object searched for, and number of objects and searchers can also be varied. A capture algorithm is presented that can determine whether a searching animal intercepts a cir...

—This study investigates the movement and growth of cohorts in a coastal fish stock by simulating animal responses to spatial heterogeneity of biotic and abiotic conditions in a dynamic marine landscape. A coastal bay is modeled using spatial and temporal data on prey distribution, benthic habitat, depth, and salinity. Prey abundance and salinity vary daily through an annual cycle to create a s...

Neuronal development and neurite regeneration depends on the locomotion and navigation of nerve growth cones (GCs). There are few detailed descriptions of the GC function and structure in the adult auditory system. In this study, GCs of adult dissociated and cultured spiral ganglion (SG) neurons were analyzed in vitro utilizing combined high resolution scanning electron microscopy (SEM) and tim...

Bilirubin, a powerful endogenous antioxidant, is one of the catabolites of heme oxygenases (HOs). In this study, the plasma bilirubin concentration was measured to establish bilirubin kinesis after traumatic brain injury (TBI). Furthermore, in in vitro studies, the free radical scavenging activity and antioxidant potency of bilirubin was also investigated at various concentrations, including ph...

BACKGROUND Regional left ventricular (LV) diastolic wall motion abnormalities detected by color kinesis (CK), an echocardiographic technique, may be a more sensitive measure to postischemic damage following coronary spasm than parameters of global diastolic function. METHODS AND RESULTS Regional LV diastolic wall motion was evaluated by using CK in 18 patients with variant angina on the day f...

Avian cranial kinesis, in which mobility of the quadrate, pterygoid and palatine bones contribute to upper bill elevation, is believed to occur in all extant birds. The most widely accepted model for upper bill elevation is that the quadrate rotates rostrally and medially towards the pterygoid, transferring force to the mobile pterygoid-palatine complex, which pushes on the upper bill. Until no...

Vertebrate Morphology, Session I. Malcolm T. Jollie indicated that the "spits" observed by others in the cranial bones of caecilians may represent a complex sensory system similar, at least in function and innervation, to the lateral line system of acquatic amphibians. Kinesis in all tetrapods may be traced back to the crossopterygian condition, according to Walter J. Bock. The presence of a ki...
