Improved techniques for studies of adipocyte cellularity and metabolism1

Journal of Lipid Research, 1977
Two methods are described for the study of adipose tissue cellularity and metabolism. In the first, 8 M urea was used to liberate osmium tetroxide-fixed adipocytes from the connective tissue matrix.

Lipid fixation during preparation of chloroplasts for electron microscopy

Journal of Lipid Research, 1968
Reaction of osmium tetroxide with isolated spinach chloroplasts fixed completely the glycolipids, phosphatidyl glycerol, and phosphatidyl choline. Under the same reaction conditions only 30% of the chlorophyll was fixed.Reaction of potassium permanganate

Methods for the determination of adipose cell size in man and animals

Journal of Lipid Research, 1968
Four methods for the sizing of adipose cells in small samples of human or animal adipose tissue are compared. These methods depend on the preparation of cell suspensions by incubation of the tissue with collagenase or by prolonged fixation with osmium ...

Towards conformationally-locked difluorosugar analogues : an unexpected sense of dihydroxylation [PDF]

, 2004
Difluorinated cyclooctenones, synthesised using RCM, can be used as templates for stereoselective oxidative transformations to products that undergo transannular reactions to afford conformationally-locked analogues of 2-deoxy-2,2-difluorosugars with ...

Lipid-laden multilocular cells in the aging thymus are phenotypically heterogeneous [PDF]

, 2015
Intrathymic lipid-laden multilocular cells (LLMC) are known to express pro-inflammatory factors that might regulate functional activity of the thymus. However, the phenotype of ageassociated intrathymic LLMC is still controversial.
