Four identical 37.5 Liter UASB reactors R1, R2, R3 and R4 were used to study the effect of sulfate concentration on granule formation. Diluted molasses with COD range 1000–1300 mg/l were used as feed and acclimated cow manure was used as seed. Concentration of sulfate ions in the four reactors were 100, 500, 1000 and 1500mg/l. Granules were observed in R2 after 33 days from startup time, while ...

extended-release matrix tablets of diltiazem hydrochloride (dtz) were prepared using waxy materials alone or in combination with kollidon sr. matrix waxy materials were carnauba wax (cw), bees wax (bw), cetyl alcohol (ca) and glyceryl monostearate (gms). dissolution studies were carried out by using a six stations usp xxii type 1 apparatus. the in vitro drug release study was done in 1000 ml ph...

The spherical porous granules of octacalcium phosphate (OCP) and hydroxyapatite (HA) have the potential for applications in scaffolds bone regeneration. alpha-tricalcium were immersed a pH 5.0 buffer solution that contained 0.1 mM ascorbic acid (AscP), an osteogenesis-promoting drug, at 60 °C. This resulted fabrication AscP-loaded HA/OCP granules. OCP HA phases concentrated surface interior gra...

OBJECTIVE To inspect cigarettes with a triple granular filter for charcoal granules on the cut filter surface and, if present, to determine whether the charcoal granules on the filter are released during smoking. DESIGN 400 Lark cigarettes in 20 packs were examined individually by each of three investigators for the presence of charcoal granules on the cut surface of the cellulose acetate fil...

To study the interaction between low-density lipoprotein (LDL) and granules from rat serosal mast cells in vitro, mast cells were stimulated with the degranulating agent 48/80 to induce exocytosis of the secretory granules. Subsequent incubation of the exocytosed granules with 125I-LDL resulted in binding of the labelled LDL to the granules. When increasing amounts of agent 48/80 were added to ...

Cytoplasmic RNA granules in germ cells (polar and germinal granules), somatic cells (stress granules and processing bodies), and neurons (neuronal granules) have emerged as important players in the posttranscriptional regulation of gene expression. RNA granules contain various ribosomal subunits, translation factors, decay enzymes, helicases, scaffold proteins, and RNA-binding proteins, and the...

In post-ganglionic sympathetic neurons, biochemical and electron-microscopical evidence indicate that noradrenaline is stored within granules which, although smaller, resemble adrenal medullary chromaffin granules in some respects. This resemblance between neuronal and adrenal medullary granules has been extended by immunological and enzymic investigations which show that sympathetic nerve gran...

Morphometric evidence derived from studies of mast cells, pancreatic acinar cells and other cell types supports a model in which the post-Golgi processes that generate mature secretory granules can be resolved into three steps: (1) fusion of small, Golgi-derived progranules to produce immature secretory granules which have a highly constrained volume; (2) transformation of such immature granule...
