background : there are growing evidences for chromosomal radioadaptive response in human lymphocytes . highly variable inter- and intra-individual responses have been reported. some individuals are non-responders and even in some donors the frequency of chromatid aberrations induced by a challenge dose increases by pre-exposure to an adapting dose. it has been proposed that the lack of radioada...

this study compares the functional capabilities of different metacarpal fixation constructs under physiological loadings in an attempt to identify the optimal construct rather than the strongest one. one hundred and twenty-six preserved human metacarpals were mechanically tested after oblique osteotomies and internal fixation. maximum load to failure, average structural rigidity, and energy abs...

This talk discusses our investigation into an objective presence measure. In our experiment, we investigated the correlation among a post-experiment presence questionnaire, human peripheral response (electrodermal activity and skin temperature), and a behavioral-presence questionnaire. Our findings show that the measures do correlate and have use as a potential objective surrogate for subjectiv...

Background: Spermatozoa are able to sense an attractant molecule gradient and as a consequence, orient their movement towards the source of the attractant. This mechanism is known as sperm chemotaxis. In recent years, our laboratory contributed to the knowledge of several features of mammalian sperm chemotaxis. These include the size and physiological state of the chemotactic sperm population, ...

This study assessed the effects of natural expressive tendencies on physiological response to stress. Male undergraduates were unobtrusively observed while watching a stressor videotape. On the basis of the subjects' facial responsiveness to the film, a group of 23 natural expressers and 22 natural inhibitors were selected and exposed to a threat of shock situation during which heart rate, resp...

Introduction: It has been hypothesized that dose sculpting/painting of physiological imagingdefined subvolumes of the tumors by intensity-modulated radiotherapy could lead to a better outcome than distributing a uniform dose within a target volume defined by anatomical imaging (1). Our goal is to develop a general method to delineate the subvolumes of a tumor based upon multiple physiological i...
