High-resolution in situ hybridization and TUNEL staining with free-floating brain sections.
We applied in situ hybridization and the TUNEL technique to free-floating (vibratomed) sections of embryonic and postnatal mouse CNS. Full-length cDNAs specific for oligodendrocyte- or astrocyte-specific genes were labeled with digoxigenin using the random primer method. With paraformaldehyde-fixed sections, the nonradioactive in situ hybridization method provides detection of individual, very ...
متن کاملFree Basis Consisting of Strictly Small Sections
Let X be a d-dimensional projective arithmetic variety and L an invertible sheaf on X . We fix a C∞-hermitian metric | · | of L. In Arakelov geometry, we frequently ask whether H(X,L) has a free basis consisting of strictly small sections. However, we know few about this problem in general. For example, Zhang [7] proved that H(X,nL) possesses a free basis as above for n ≫ 1 if the following con...
متن کاملNasolabial Wrinkle Classification
Categorization of facial wrinkles is used in dermatology studies to determine the efficacy of a certain treatment over a certain period of time. These studies, however, are limited by the fact that when dermatologists assign these categorizations, it is done so through qualitative, in-vivo observation. The objective of this study was to train a computer to categorize nasolabial wrinkles into on...
متن کاملWrinkle motifs in thin films
On length scales from nanometres to metres, partial adhesion of thin films with substrates generates a fascinating variety of patterns, such as 'telephone cord' buckles, wrinkles, and labyrinth domains. Although these patterns are part of everyday experience and are important in industry, they are not completely understood. Here, we report simulation studies of a previously-overlooked phenomeno...
متن کاملA Method of Staining Thin Sections with Lead Hydroxide for Precipitate-free Sections
Staining of thin sections results in greater contrast which facilitates focusing and the observation of fine structure. Lead hydroxide, as suggested by Watson (1), has become increasingly popular as a stain for electron microscopy. However, when lead hydroxide is exposed to the carbon dioxide of air, lead carbonate forms and is deposited on the sections as fine, needle-like crystals, large amor...
