Augmentation of keratinocyte differentiation by the epidermal mitogen, 8-bromo-cAMP
(Elsevier, 1983-11)
The effect of the epidermal mitogen, 8-bromo-cAMP, on keratinocyte differentiation was studied. A 3 x 10-4 M dose of 8-bromo-cAMP was added to primary neonatal mouse epidermal keratinocyte cultures that slowly proliferate, ...
Galanin inhibits rat pancreatic amylase release via cholinergic suppression
(Elsevier, 1992)
The effects of galanin on pancreatic exocrine function were examined using rat pancreatic tissues. In anesthetized rats, galanin (40 [mu]g/kg/h) decreased amylase secretion stimulated by 2-deoxy glucose (5.8 +/- 0.1 vs. ...
Lack of effect of dihydroergotamine on endothelial and smooth muscle cell proliferation and endothelial cell prostanoid production
(Springer-Verlag; Birkhäuser Verlag, 1988-03)
The most important effect of dihydroergotamine is venoconstriction, but certain metabolic effects and changes in vessel prostanoid activity have also been suggested. In this study endothelial cell production of 6-keto PGF ...
Epidemiology of Aortic Aneurysm Repair in the United States from 1993 to 2003
(Blackwell Publishing Inc, 2006-11)
The epidemiology of abdominal aortic aneurysm (AAA) disease has been well described over the preceding 50 years. This disease primarily affects elderly males with smoking, hypertension, and a positive family history ...
Identification of low molecular weight proteins isolated by 2-D liquid separations
(John Wiley & Sons, Ltd., 2004-07)
Proteins with molecular mass ( M r ) <20 kDa are often poorly separated in 2-D sodium dodecyl sulfate polyacrylamide gel electrophoresis. In addition, low- M r proteins may not be readily identified using peptide mass ...
Stimulation of myenteric plexus neurite outgrowth by insulin and insulin-like growth factors I and II
(Elsevier, 1992)
A defined culture medium containing insulin, insulin-like growth factor I (IGF-I) or insulin-like growth II (IGF-II) supported morphological development of myenteric plexus neurons derived from neonatal guinea pigs. Insulin ...
Automated integration of monolith-based protein separation with on-plate digestion for mass spectrometric analysis of esophageal adenocarcinoma human epithelial samples
(WILEY-VCH Verlag, 2006-09)
A unique approach of automating the integration of monolithic capillary HPLC-based protein separation and on-plate digestion for subsequent MALDI-MS analysis has been developed. All liquid-handling procedures were performed ...
Isoelectric focusing nonporous silica reversed-phase high-performance liquid chromatography/electrospray ionization time-of-flight mass spectrometry: a three-dimensional liquid-phase protein separation method as applied to the human erythroleukemia cell-line
(John Wiley & Sons, Ltd., 2001-09-30)
A liquid-phase three-dimensional protein separation method has been developed that is used to separate the cytosolic fraction of a HEL cell lysate via isoelectric focusing (IEF), nonporous silica (NPS) reversed-phase ...
Design for improved resolution in a time‐of‐flight mass spectrometer using a supersonic beam and laser ionization source
(The American Institute of Physics, 1985-03)
This article describes the design of a time‐of‐flight mass spectrometer (TOFMS) constructed for optimum use with resonance‐enhanced multiphoton ionization spectroscopy in supersonic beams. The use of the supersonic beam ...
Design of a pulsed valve for high‐pressure NH3 injection into supersonic beam/mass spectrometry
(The American Institute of Physics, 1988-11)
A novel design of a pulsed valve for high‐pressure injection of NH3 for supersonic jet expansions is presented. This valve can operate up to 200‐atm reservoir pressure at 180 °C with a pulse width down to 100 μs. This valve ...
