S OF POSTERS AND DEMONSTRATIONS Interactive computer simulations for teaching basic concepts in respiratory physiology Robert A. Furilla and A. H. Sillau Department of Physiology, University of Puerto Rico, School of Medicine, San Juan, PR 00936-5067 Over the years, we have become aware that classes are not the same as they once were. Class size continues to grow, students are unaware of fundam...

This article is from a symposium presented at the annual meeting of the Human Anatomy and Physiology Society (HAPS) on June 11, 2000. The presentation was funded under the auspices of a National Science Foundation Course, Curriculum, and Laboratory Improvement Program entitled "Development of Active Learning Materials for Physiology and Functional Anatomy: A Cooperative HAPS-APS Initiative." Th...

The distal convoluted tubule is the nephron segment that lies immediately downstream of the macula densa. Although short in length, the distal convoluted tubule plays a critical role in sodium, potassium, and divalent cation homeostasis. Recent genetic and physiologic studies have greatly expanded our understanding of how the distal convoluted tubule regulates these processes at the molecular l...

six patients with mitral stenosis complicated by renal artery embolism studied prospectively are presented. in five patients there was unilateral and in one patient bilateral renal artery involvement. the diagnosis was confirmed by intravenous pyelography, retrograde pyelography, renal angiography, renal scan or a combination of these. all had atrial fibrillation, proteinuria and elevated ldh l...

primary rhabdomyosarcoma (rms) of the kidney is a rare malignant mesenchymal tumor with an aggressive clinical course. adult renal rms is typically a pleomorphic histologic subtype and only a few cases have ever been reported. we herein present a new case of renal rms of the embryonal histologic subtype in a 26-year-old woman.

A computational model of porous media at the microscale will be presented. A collection of solid particles is placed within a regular fluid domain. The particles are represented with less detail by a ‘force cloud’ centered at a given point. Internal no-slip conditions are approximately achieved. This method is easy to implement, computationally inexpensive, and may be used to represent complex ...

Acid-base homeostasis and pH regulation are critical for both normal physiology and cell metabolism and function. The importance of this regulation is evidenced by a variety of physiologic derangements that occur when plasma pH is either high or low. The kidneys have the predominant role in regulating the systemic bicarbonate concentration and hence, the metabolic component of acid-base balance...
