The presence of neuron-specific enolase (NSF) and neurofilament proteins (NFP) immunoreactivities (IR) was investigated in dorsal root ganglia (DRG) of adult rats at cervical, thoracic, lumbar and sacral levels. All neurons display NSE-like IR with a variable intensity of immunostain which is not related to the neuronal size. Conversely, the antibody(More)
The epidermal growth factor (EGF) concentration in bile is high (approximately 150 fold higher than that in plasma), but little is known about its physiological control. Acute administration of the alpha 1-adrenergic agonist phenylephrine (1.7 mg/kg, iv) to male mice produced a rapid increase in the EGF concentration in bile. We suggest that this EGF(More)
The localization of S-100 protein-, glial fibrillary acidic protein- and vimentin-like immunoreactivity has been studied in dorsal root ganglia of the rat using monoclonal antibodies. A positive reaction for both S-100 protein-like and vimentin-like was found in satellite and Schwann cells. In addition, some large and intermediate sized neurons also result(More)
BACKGROUND Pancreatic islet grafts are difficult to manipulate and implant in the recipient site mainly because they are formed by a group of cells suspended in a solution. This physical property determines various characteristics that are unique for pancreatic islet transplantation. The purpose of this study was to evaluate the role of fibrin glue as a(More)
OBJECTIVE Enzymatic digestion of the pancreas is a fundamental step in islet isolation and there are many ways to administer the enzyme during procurement. The aim of this study was to evaluate the influence of different methods of Liberase delivery during pancreas harvest on the quality and quantity of islets. METHODS Depending on the type of Liberase(More)
We characterized the surface phenotype of B cells from HIV+ children in order to better understand the biology of B cell dysregulation. Twenty-nine HIV-infected, twenty-one exposed, and nineteen age-matched control children were studied for expression of CD5, CD10, CD21, CD23, CD25, CD62L, CD71, and CD69. We conclude that, despite persistent high(More)
BACKGROUND Fibrin glue has proven to be a good delivery system for cell transplantation but the factors that influence the fibrin-cell relationships are not well understood. The purpose of this study was to assess the effect of different concentrations of fibrin glue components (thrombin and fibrinogen) on the function of pancreatic islets. METHOD Islets(More)
Acetylcholinesterase and fluoride-resistant acid phosphatase activities were contrasted in alternative serial sections of rat dorsal root ganglia. The morphometric analysis demonstrated no correlation between cellular size and enzymatic activity. Differences with previous works in this area are discussed.
