Adult rat hepatocytes cultured in a collagen sandwich system maintained normal morphology and a physiological rate of albumin secretion for at least 42 days. Hepatocytes cultured on a single layer of collagen gel essentially ceased albumin secretion within 1 wk but could recover function with the overlay of a second layer of collagen gel. This culture(More)
In an effort to reconstruct the cellular polarity normally found in the liver, adult rat hepatocytes were sandwiched between two layers of hydrated rat tail tendon collagen matrix. Functionally, sandwiched hepatocytes maintained the secretion of albumin, transferrin, fibrinogen, bile acids, and urea for at least 6 weeks, whereas cells cultured on a single(More)
OBJECTIVE To review the surgical experience with pectus excavatum chest deformities at UCLA Medical Center during a 30-year period. BACKGROUND Pectus excavatum is a relatively common malformation that is often symptomatic; however, children's physicians often do not refer patients for surgical correction. METHODS Hospital records from 375 patients who(More)
Current methods of cryopreservation of hepatocytes in single cell suspensions result in low overall yields of hepatocytes, demonstrating long-term preservation of hepatocellular functions. A novel culture method has recently been developed to culture liver cells in a sandwich configuration of collagen layers in order to stabilize the phenotypic expression(More)
An intravenous (i.v.) formulation of mycophenolate mofetil (MMF; CellCept, Roche Pharmaceuticals, Inc., Palo Alto, CA) that will enable its administration to patients unable to tolerate oral medication is available. Two separate studies, an open-labeled pharmacokinetic (PK) study and a double-blind safety study, were performed. Within 24 h after transplant,(More)
Despite more than 30 yr of research and development, an artificial liver has still not yet become clinical reality. Although previous attempts using a multiplicity of techniques including hemodialysis, hemoperfusion, plasma exchange, extracorporeal perfusion, and crosshemodialysis have shown minor improvement in patients with acute hepatic failure, limited(More)
INTRODUCTION Previous studies regarding musculoskeletal injuries sustained during war have been limited by a lack of specificity regarding wounds incurred by combat-specific personnel. This investigation endeavoured to develop a comprehensive catalogue of the extent of musculoskeletal trauma, as well as the frequency of distinct injuries, among soldiers(More)
The survival of infants with tracheoesophageal fistula was stratified by David J. Waterston et al. in 1962. This classification has been used as a guide to direct the timing of operative intervention in these infants. This study examines the current applicability of this classification system. The hospital records of 64 infants with esophageal atresia(More)
CECS is a common source of lower extremity disability among young athletic cohorts and military personnel. The five cardinal symptoms are pain, tightness, cramps, weakness, and diminished sensation. History and clinical examination remain the hallmarks for identifying CECS, although ICP measurements during exercise stress testing may be used to confirm(More)
