In various organs

It is manufactured by heating dicyandiamide, H2N C(NH) NH CN, either alone or in the presence of ammonia or other alkalis, in various organic solvents. Melamine is an important material in the plastics industry. Condensed with melhanal and other substances it gives thermosetting resins that are remarkably stable to heat and light. U.S. production 1980 80 000 tonnes. 

An interesting set of central nervous system properties has also been discovered and studied (Table VI-10). The work devoted to piscaine must be emphasized besides finding hypnotic properties of 2-amino-4-phenyl-thiazole on fish, the authors studied the structure of the metabolite, as well as the localization of the (radio labeled) metabolic product in various organs. Recently, thiazol-4-yl methoxyamine was shown to inhibit the development of morphine tolerance (1607). 5-Aminothiazole derivatives such as 419a were proposed as cardiovascular agents (1608, 1610). Substitution of the 5-aminothiazole radical on the cephalophosphorin structure gives a series of antibacterial products (1609). 

Hydrogen Chloride-Organic Compound Systems. The solubihty of hydrogen chloride in many solvents follows Henry s law. Notable exceptions are HCl in polyhydroxy compounds such as ethylene glycol (see Glycols), which have characteristics similar to those of water. Solubility data of hydrogen chloride in various organic solvents are Hsted in Table 10. 

Oxamide. This diamide [471 6-5] H2NCOCONH2, mol wt 80.07, is sparingly soluble in water and insoluble in various organic solvents. It... 

Rheology. PVP solubihty in water is limited only by the viscosity of the resulting solution. The heat of solution is — 16.61 kJ/mol (—3.97 kcal/mol) (79) aqueous solutions are slightly acidic (pH 4—5). Figure 2 illustrates the kinematic viscosity of PVP in aqueous solution. The kinematic viscosity of PVP K-30 in various organic solvents is given in Table 13. 

Selected physical properties of benzoic acid are given in Table 1, solubiHties in water in Table 2, solubiHties in various organic solvents in Table 3, and vapor pressures in Table 4.

The gene defective in cystic fibrosis codes for CFTR (cystic fibrosis transmembrane condnctance regulator), a membrane protein that pumps CP out of cells. If this CP pump is defective, CP ions remain in cells, which then take up water from the surrounding mucus by osmosis. The mucus thickens and accumulates in various organs, including the lungs, where its presence favors infections such as pneumonia. Left untreated, children with cystic fibrosis seldom survive past the age of 5 years. 

Incorrect - The two pathways are alternative pathways for converting carbohydrate to pyruvate, and are found in various organisms. They operate in aerobic or anaerobic conditions. 

Chemiluminescence. Cypridina luciferin emits light in various organic solvents in the presence or absence of a base. The most efficient... 

An example that refers to the third method additives can be employed is described below. Markedly enhanced enantioselectivity was reported for P. cepacia lipase and subtilisin Carlsberg with chiral substrates converted to salts by treatment with numerous Bronsted-Lowry adds or bases [63]. This effect was observed in various organic solvents but not in water, where the salts apparently dissociate to regenerate... 

Experiments were undertaken in various organic solvents and over a wide range of temperatures. 

Endosulfan residues are rapidly eliminated from tissues as suggested by a half-life of approximately 7 days estimated in a 14-day oral study in female rats (Dorough et al. 1978). Rapid elimination was also observed in a 28-day study in goats in which half-lives between 1.1 and 3.1 days were estimated for endosulfan residues in various organs and tissues (Indraningsih et al. 1993).

HPLC separation of the toxins present in various organisms during a dinoflagellate bloom in Quartermaster Harbor, Washington (A) dinoflagellates, (B) mussels, (C) littleneck clams, (D) butter clams. The toxin metabolites ("M") were later found to be the decarbamoyl form. See Ref. 4 for HPLC conditions.)...

The PBE dendron has a glass transition at about 40 °C and is soluble in various organic solvents (e.g., THF, acetone, toluene). It is therefore a moldable, thermoplastic, film-forming material. This practical feature is maintained for the lanthanide-cored dendrimer complexes. The complexes are partially miscible with poly(methyl methacrylate), affording transparent luminescence compositions by mixing in solvent. 

CR is distributed in various organs with highest concentrations in skeletal muscle, myocardium, and brain and lesser amounts in the gastrointestinal tract, uterus, urinary bladder, and kidney ( ). The CR content of liver and red blood cells is negligible so that diseases of these tissues are unlikely to increase the serum CR activity. The serum CR level begins to increase in 2-4 hours after myocardial infarction and reaches a peak in 24-36 hours and returns to normal in about 3 days. 

Invasive pathogens either aggressively invade the tissues surrounding the primary site of infeehon or are passively transported around the body in the blood, lymph, cerebrospinal fluid or pleural fluids. Some, espeeially aggressive organisms, do both, setting up a number of expansive seeondary sites of infeehon in various organs. 

In 1941, Mackinney ° published the first specific absorption coefficients for chlorophyll a and chlorophyll b in 80% acetone, quickly followed by other reports citing different solvents. Chlorophylls form aggregates in various organic solvent-water mixtures that may interfere strongly with the absorbance maximum wavelength and the shapes of spectra.
