A 6 week labyrinth walking program was pilot tested in a correctional setting and goals were to: 1) determine the feasibility of a labyrinth walking curriculum; 2) pilot test measures of health related quality of life (QOL) (pre and post-surveys) and blood pressure; and 3) examine the influence of relationship-centered teaching on subject satisfaction. Relational communication was used as a fra...

In this paper, we introduce a new approach to computeraided microtonal improvisation by combining methods for (1) interactive scale navigation, (2) real-time manipulation of musical patterns and (3) dynamical timbre adaption in solidarity with the respective scales. On the basis of the theory of well-formed scales we offer a visualization of the underlying combinatorial ramifications in terms o...

The bony labyrinth of mammals, a delicate and complex cavity within the petrosal, houses the organs of hearing and equilibrium of the inner ear. Because this region is typically lodged deep within the skull, there have been few morphological studies of the bony labyrinth in fossils—where it frequently is completely enveloped by surrounding bone and sediment matrix. The recent development of hig...

The membranous labyrinth is contained within the bony labyrinth and surrounded by perilymph. The only two 'potentially yielding' parts of the otherwise solid bony labyrinth are the oval and round windows, which by their relative movements, pressure differentials and resilience are responsible for all the functions attributed to the inner ear. In pathologies, such as trauma, infection or occasio...

In eutherian mammals, embryonic growth and survival is dependent on the formation of the placenta, an organ that facilitates the efficient exchange of oxygen, nutrients, and metabolic waste between the maternal and fetal blood supplies. Key to the placenta's function is the formation of its vascular labyrinth, a series of finely branched vessels whose molecular ontogeny remains largely undefine...

Unusual expression of interleukin-1alpha, -1beta and -6 was previously found in the epiphyseal cartilage of rat fetuses prenatally exposed to various non-steroidal anti-inflammatory drugs (NSAID, i.e., ibuprofen, piroxicam, tolmetin) and selective cyclooxygenase-2 inhibitor (DFU). The aim of the present study was to evaluate the role of placenta in such phenomenon. Morphology of the organ, thic...

Introduction The membranes of the inferior division of the labyrinth in some mammals appear more vulnerable to hydropic distention than those of the superior division. This finding in guinea pigs, cats, and humans has been attributed to the evidently thinner membranes with implied higher stress levels. Objective The objective of this study is to identify other configurational features, if any, ...

Objective To develop a three-dimensional study tool of the membranous labyrinth in order to study the pathophysiology, diagnostic workup and treatment of benign paroxysmal positional vertigo (BPPV). BPPV is the most common cause of peripheral vertigo. Its diagnosis and treatment depend on an understanding of the anatomy of the vestibular labyrinth and its position relative to the head. To date,...

In this, our second temporal bone installment, we will emphasize the vestibular portion of the labyrinth, that relating to balance and equilibrium. Before proceeding, we must again remind the reader of the basic structure of the labyrinth: an inner membranous labyrinth (endolymphatic) surrounded by an outer osseous labyrinth with an interposed supportive perilymphatic labyrinth. We recommend pe...
