Triethylammonium (2R,3R)-2,3-bis(benzoyloxy)-3-carboxypropanoate

Disposition in rats of N-pyridinium-propyl-cyclam, N-triethylammonium-propyl-cyclam, and N-[Triethylammonium]-3-propyl-[15]ane-N5, potential cartilage imaging agents.

Quaternary ammonium compounds are known to highly concentrate in articular cartilages after i.v. administration. This property was used to synthesize new potential radiodiagnostic agents for joint imaging. Pharmacokinetic study was performed in rats for three new compounds: N-pyridinium-propyl-cyclam (NPPC), N-triethylammonium-propyl-cyclam (NTPC), and N-[triethylammonium]-3-propyl-[15]ane-N5 (...

T use of antimicrobial drugs in food-producing animals can result in antimicrobial drug–resistant infections in humans. A good example is the use of fluoroquinolone in poultry and the emergence of fluoroquinolone-resistant Campylobacter infections among humans. However, topics of intense debate include the widespread use of antimicrobial drugs in animals, the extent to which antimicrobial drug ...

Planar point location is a problem in which we are given a planar graph (with no crossings) defining a map, such as the boundary of GUI elements. Then we wish to support a query that takes a point given by its coordinates (x, y) and returns the face that contains it (see Figure 1 for an example). As is often the case with these problems, there is both a static and dynamic version of this proble...

Exotic Red-billed Leiothrix Leiothrix lutea numbers have increased in southern, western and central part of Japan since the early 1980’s. Unlike most naturalized birds, this species mainly breeds in natural deciduous forests. We researched the breeding bird density in a deciduous forest on Mt. Tsukuba (877 m), a major breeding area of leiothrix in central Japan, in 1994 and 1995. Leiothrix bred...
