As a result of the ambiguity and complexity surrounding anaerobic digester foaming, efforts have been made by various researchers to understand the process of anaerobic digester foaming so as to proffer a solution that can be universally applied rather than site specific. All attempts ranging from experimental analysis to comparative review of other process has not fully explained the condition...

To clarify the mode of secretion of specific atrial granules, rat atrial muscle cells were examined by transmission electron microscopy. Atrial granule formation and exocytotic features of granules were clearly seen. Abrupt breaks in the unit membrane structure of mature granules were observed in thin sections, but these breaks were not detected in freeze-fracture replicas. These findings suppo...

A common feature of temporal lobe epilepsy and of animal models of epilepsy is the growth of hippocampal mossy fibers into the dentate molecular layer, where at least some of them innervate granule cells. Because the mossy fibers are axons of granule cells, the recurrent mossy fiber pathway provides monosynaptic excitatory feedback to these neurons that could facilitate seizure discharge. We us...

Experimental work was carried out to investigate the influence of impeller speed, granulation time, binder mass and their interactions on granule size distribution, mean size and binder content distribution in a conical high shear granulator. It was observed that the response of high shear granulation to changes in process parameters varies significantly from one operating condition to anot...

Increased energy metabolism in the circulating blood platelet plays an essential role in platelet plug formation and clot retraction. This increased energy consumption is mainly due to enhanced anaerobic consumption of glucose via the glycolytic pathway. The aim of the present study was to determine the role of glucose transport as a potential rate-limiting step for human platelet glucose metab...

The dentate gyrus is the chief route of excitatory input into the hippocampal formation and is thus crucial for appropriate function of the hippocampus in learning and memory. Many pathological states associated with histological abnormalities in the dentate are likely to have their origins during development. These disorders include generalized abnormalities of neuronal migration, e.g. reeler ...

The occurrence of simultaneous partial nitrification, anaerobic ammonium oxidation and denitrification (SNAD) observed in a single partially aerated full-scale bioreactor treating landfill-leachate is reported in this paper. At present, the full-scale bioreactor is treating an average leachate flow of 304 m(3)d(-1) with a sludge retention time between 12 and 18d. The average COD, NH(4)(+)-N and...

Germ granules, specialized ribonucleoprotein particles, are a hallmark of all germ cells. In Drosophila, an estimated 200 mRNAs are enriched in the germ plasm, and some of these have important, often conserved roles in germ cell formation, specification, survival and migration. How mRNAs are spatially distributed within a germ granule and whether their position defines functional properties is ...
