Close observations of immunofluorescence signals showed that there are three different staining patterns, which correspond to three different nucleolar compartments FC (Fibrillar center), DFC (dense fibrillar component), and GC (granular component). Nucleolus is surrounded by heterochromatin. When the cells are in very active state of its proliferation, the nucleolar compartments and heterochromatin are integrated into a highly intricate structure called nucleolonema . A recent study has suggested that the chromatin associated with the nucleolus is less mobile than... 

There are currently no mathematical techniques to predict blending behavior of granular components without prior experimental work. Therefore, blending studies start with a small scale, try-it-and-see approach. The first portion of this chapter is concerned with the following typical problem a 5-ft - capacity tumble blender filled to 50% of capacity and run at 15 rpm for 15 minutes produces the desired mixture homogeneity. What conditions... 

Additional in vitro effects of feverfew include inhibition of histamine release from mast cells and granular components from leukocytes inhibition of smooth muscle contraction cytotoxic effects on human tumor cell lines and antimicrobial effects against gram-positive bacteria, yeasts, and filamentous fungi. 

The horseshoe crab hemolymph contains mainly one type of blood cells called amoebocytes (Fig. 9.3), which are extremely sensitive to LPS. During a Gram negative infection, the amoebocytes release granular components into the plasma...

Bulk blending of granular components is a process well known in the fertilizer business where it is common to blend various proportions of straight fertilizers to yield appropriate N,P,K grades for specific applications. A standard rule of thumb for fertilizer blending is to maintain a component median diameter difference of less than 5% [11]. Consideration of the component size distribution or spread is also important to consider when comparing properties of materials intended for blending [12]. 

Although the molecules of a single-phase liquid system may differ, and may diffuse at different rates, they will ultimately achieve a random distribution within the confines of the system. Particulate and granular components do not usually have the constant properties of molecular species and can differ widely in physical characteristics. Thus a mixing motion which depends on identical particulate properties is unlikely to achieve its objective. More commonly such a mixer would produce a grading or segregation of...

Fig. 5 Antibody labeling of nucleolar component parts by iromunoelectron microscopy (a, c, and e) and indirect immunofluorescence (b, d, and f). (a and b) Fibrillar centers (FC) labeled with antibody to RNA polymerase I. (c and d) Dense fibrillar component (DFC) labeled with antibody to fibrillarin. (e and f) Granular component (GC) labeled with antibody to protein B23. (a, c, and e) Scale bar, 0.5 /urn. (b, d, and f) Scale bar, 5 /im.

Fig. 6 Distribution of flbrillar centers in PHA-stimulated human lymphocytes at 0 (a and d), 24 (b and e), and 48 hr (c and f) as visualized by conventional electron microscopy (a-c) and by indirect immunofluorescence (d-f) using a human autoantibody to RNA polymerase I. FC, Fibrillar center, DFC, dense flbrillar component G, granular component. The resting, unstimulated lymphocyte (a and d) contains a single large FC (arrowhead in d) that increases in number and decreases in size as the nucleolus grows in size with continued stimulation, (a-c) Scale bar, 0.5 /zm. (d-f) Scale bar, 5 /i.m.

Friction sensitivity studies have shown a relationship to ignition temperature and heat of reaction, but the critical factor in friction sensitivity appears to be the presence in a composition of a significant amount of a gritty or hard granular component. Such a material, when exposed to frictional action, will generate hot spots that can lead...
