Study of precorneal tear film thickness and structure by interferometry and confocal microscopy.

 · 1970

Past measurements of precorneal tear film thickness in rabbits and humans gave values of 4-7 microns. These have been the accepted values. However, measurements presented in this report are much highe…

Quantitative annular dark-field imaging of single-layer graphene.

 · 1970

A quantification procedure for annular dark-field (ADF) imaging, in which a quantitative contrast is given as a scattering intensity normalized by an incident probe current, is presented. The obtained…

Absence of CSF-1-dependent macrophages does not improve function of transplanted islets of Langerhans.

 · 1970

A role of macrophage-mediated inflammatory events in early islet graft loss is increasingly acknowledged. Osteopetrotic mice (op/op) have a complete absence of CSF-1, and thus of most tissue macrophag…

Identification of in vitro parameters predictive of graft function: a study in an animal model of islet transplantation.

 · 1970

The quality of human islets is one of the factors decisive for the success of human islet transplantation. Several parameters have been proposed to characterize islet quality, but none of them has bee…

Dopaminergic growth patterns induced by striatal and cortical grafts show differences in sensitivity to increased striatal trophic activity induced by haloperidol.

 · 1970

During development, dopaminergic neurons innervate the developing striatal target, forming two different growth patterns: a patchy growth and a diffuse growth. Chronic treatment with the dopamine anta…
