Magnetic resonance imaging (MRI) of the knee articular cartilage is possible owing to the contrast provided by different signal intensities of adjacent menisci and subchondral bone. The objective of this study was to determine the accuracy of MRI in quantitatively detecting thinning and focal defects of articular cartilage in vivo. High resolution MRI was performed followed by dissection of the...

there are many studies about epidural fibrosis after surgical manipulation of the spine. we have studied formation of the post laminectomy epidural fibrosis after application of two materials (silicone and teflon) in this report. this expriment is on two groups of rats. two separated laminectomies were done in each rat, one serving as control while in the other laminectomy spaces silicone was u...

Anatomy has historically been a cornerstone in medical education regardless of nation, racial background, or medical school system. By learning gross anatomy, medical students get a first "impression" about the structure of the human body which is the basis for understanding pathologic and clinical problems. Although the importance of teaching anatomy to both undergraduate and postgraduate stud...

Neurosensory epithelia in the inner ear are the crucial structures for hearing and balance functions. Therefore, it is important to understand the cellular and molecular features of the epithelia, which are mainly composed of two types of cells: hair cells (HCs) and supporting cells (SCs). Here we choose to study the inner ear sensory epithelia in adult zebrafish not only because the epithelial...

Introduction The anatomy of the donkey and how it differs from that of the horse rarely receives mention in standard veterinary anatomy textbooks used in the western world. There is also limited material on this subject readily accessible in the current literature. As a result, the donkey is often presumed to be morphologically the same as the horse, and there are far more similarities between ...

Pathologic findings encountered during cadaver dissection provide an opportunity for integrating the preclinical basic sciences and encouraging critical thinking. The objective of this study was to determine whether it is possible to make a pathologic diagnosis of an unknown mass from an embalmed cadaver. Diagnoses would have to be based solely on gross and microscopic appearance of tissue, wit...
