Quick cartilage transformation
eukocytes have a better chance of sticking to neighboring cells with the right ligands if they rotate on their way by, based on results from Dwir et al. (page 649). Flowing leukocytes are captured via L-selectin interactions with carbohydrate ligands on vessel walls and subsets of other leukocytes. L-selectin is an unusual adhesive molecule—shear stress improves its adherance to ligands, wherea...
متن کاملProteoglycans in articular cartilage revealed with a quick freezing and deep etching method.
OBJECTIVES To clarify the three dimensional ultrastructure of proteoglycans, and their relationship with other matrix components in articular cartilage. METHODS Specimens from rat femoral heads were examined using three techniques: (1) Histochemical staining with cationic polyethyleneimine (PEI), using a pre-embedding or a postembedding method. Some tissues were pretreated with chondroitinase...
متن کاملUltrastructural study of upper surface layer in rat mandibular condylar cartilage by quick-freezing method.
The purpose of the present study is to clarify native ultrastructures of upper surface layers of the rat mandibular condylar cartilage in vivo by a quick-freezing method. The mandibular cartilaginous tissues were removed with their articular discs attached without opening the lower joint cavity. The specimens were processed for light microscopy, transmission or scanning electron microscopy. Dee...
متن کاملQuick Summary
Quick Summary is an innovate implementation of an automatic document summarizer that inputs a document in the English language and evaluates each sentence. The scanner or evaluator determines criteria based on its grammatical structure and place in the paragraph. The program then asks the user to specify the number of sentences the person wishes to highlight. For example should the user ask to ...
متن کاملQuick Shaving
Arc-consistency plays such a key role in constraint programming for solving real life problems that it is almost the only algorithm used for reducing domains. There are a few specific problems for which a stronger form of propagation, often called shaving, is more efficient. Nevertheless, in many cases, shaving at each node of the search tree is not worth doing: arc-consistency filtering is muc...
