Independent measures of insulin secretion and insulin sensitivity during the same test: the glucagon-insulin tolerance test.

Background. To validate a test for independent assessment of insulin secretion and insulin sensitivity during the same occasion for metabolic studies in clinical practice, i.e. combined glucagon-stimulated C-peptide test and insulin tolerance test (GITT). Subjects and methods. We measured C-peptide response to 0.5 mg of intravenous glucagon followed 30 min later by administration of 0.05 U kg(-1)

Water, well-being and social complexity in insula V1 : A Pompeian city block revisited

Swedish archaeologists have been working in Pompeii since 2000. Our fieldwork has consisted mainly of the study of standing walls and cleared floor levels in a city block unearthed in the 19th century and of the production of a comprehensive documentation, presented in an open access publication: www.pompejiprojektet.se/insula.php. The perspective of the present paper is the insula as a whole. Its

The role of calcium in neutrophil granule-phagosome fusion.

During phagocytosis, neutrophils kill microorganisms by delivering antimicrobial substances to the phagosome. For this, the intracellular targeting and fusion of granules must be strictly regulated and a dependence on the cytosolic concentration of free calcium has been suggested. New evidence show that different mechanisms regulate early and late stages of Fc receptor-mediated phagocytosis. The e

Laser and synchrotron radiation pump-probe x-ray diffraction experiments

Recent developments have allowed x-ray diffraction techniques at synchrotron radiation facilities to be employed with a temporal resolution of around 1 ps. These developments are the availability of firstly, high brightness third-generation x-ray sources, secondly, passively mode-locked lasers with 100 fs temporal duration and thirdly, averaging streak cameras with sub-picosecond temporal resoluti
