Cholinergic and GABAergic innervation of the hippocampus plays an important role in human memory function and rat spatial navigation. Drugs which block acetylcholine receptors or enhance GABA receptor activation cause striking impairments in the encoding of new information. Lesions of the cholinergic innervation of the hippocampus reduce the amplitude of(More)
The extraosseous tissue contribution to diaphyseal fracture callus has been investigated using a rabbit tibial fracture model and osteocalcin immunocytochemistry. The extraosseous tissues were isolated for study by reaming and nailing an osteotomy and excising 2 cm of periosteum on either side of the osteotomy. Specimens obtained from the healing fractures(More)
An immunocytochemical method was used to localise osteocalcin-producing cells during fracture healing in a rabbit model. In preliminary studies, tibial growth plates from young rabbits were used as a source of new bone formation, in order to determine the optimal tissue preparatory techniques. In the present study, a tibial shaft fracture was created in(More)
OBJECTIVE To examine and compare in vitro basal and insulin-stimulated glucose uptake in human omental and subcutaneous adipose tissue derived from lean, overweight or obese individuals, and in those with central or peripheral obesity. DESIGN In vitro study of basal and insulin-stimulated 2-deoxyglucose uptake in human omental and subcutaneous adipose(More)

Cross-chip latencies now make multicore architectures resemble distributed systems. The design of distributed protocols is notoriously error-prone, particularly when their analysis is based on the use of global time. Classical memory consistency models for parallel programming, such as linearisability, uses such a global ordering. This talka examines the(More)
48 BIOCYCLE c OMPOSTING is increasingly b e coming the preferred method of treatment of municipal sludges because the process produces a marketable end-product that can be used as a soil conditioner and organic fertilizer. The successful operation of in-vessel (mechanical) and windrow systems depends on the mixing of large amounts of sawdust bulking agent(More)
