Evaluation of the effect of three calcium phosphate powders on osteoblast cells
The aim of the present study was to assess the effect of three calcium phosphate powders entering in the composition of bone substitute materials on osteoblast-cells activity. These powders were hydroxyapatite...

Synthetic hispidin, a PKC inhibitor, is more cytotoxic toward cancer cells than normal cells in vitro
The trypanocidal activity of naturally occurring 6-(3,4-dihydroxystyryl)-4-hydroxy-2-pyrone (hispidin) prompted us to examine its cytotoxic activity toward normal and cancerous cells in culture. Hispidin synth...

Characterization of a specific signal from human pancreatic tumors heterotransplanted into nude mice
In a previous study, we demonstrated the existence of a 3.2 ± 0.2 ppm peak in the1H NMR spectrum at 60 MHz from human pancreatic adenocarcinomas (Capan-1 cell) heterotransplanted intonude mice. This peak, which i...

Anion channels in a human pancreatic cancer cell line (Capan-1) of ductal origin
Transepithelial solute transport and bicarbonate secretion are major functions of pancreatic duct cells, and both functions are thought to involve the presence of chloride channels in the apical membrane of th...

Creatine phosphate as energy source in the cerulein-stimulated rat pancreas study by31P nuclear magnetic resonance
Stimulation of the rat exocrine pancreas by cerulein induces a variety of cellular processes, some of which require the expenditure of energy. In this study, changes in the amounts of various energy metabolite...

Ultrastructural study of pancreatic B cell regeneration in newborn rats after destruction by streptozotocin
An ultrastructural study of endocrine cells was performed in the pancreas of rats treated with a single dose of streptozotocin on the day of birth. Most of the B cells present at birth were destroyed by strept...
