Polymorphism of Spironolactone
Journal of Pharmaceutical Sciences, 1991Single crystals of two polymorphic and four solvated crystalline forms of spironolactone (C24H32O4S) were obtained using different solvents. The morphology, symmetry, and crystallographic parameters were determined for all crystal forms except for the one obtained from methanol.

An evaluation of entropies and enthalpies of transition and fusion and a comparison of X-ray diffraction patterns and IR spectra of polymorphic forms of structurally related compounds were undertaken to obtain information which might prove useful in correlating the frequency of occurrence of polymorphism with certain aspects of chemical structure ...

The polymorphisms of fucosyltransferases
Legal Medicine, 2001The alpha(1,2)fucosyltransferase Se enzyme regulates the expression of the ABH antigens in secretion. Secretors, who have ABH antigens in their saliva, have at least one functional Se allele in the FUT2 locus, while non-secretors, who fail to express ABH antigens in saliva, are homozygous for the non-functional se allele. Molecular analyses of the FUT2

Encapsulation and Polymorphism
1998This chapter discusses the encapsulation and polymorphic features of Java. It illustrates how the encapsulation facilities can allow quite fine-grained control over the visibility of elements of your programs. The concept of packages is also discussed, along with some concrete examples. The polymorphic nature of Java concludes the chapter.

The polymorphism of sulphathiazole
International Journal of Pharmaceutics, 1981Abstract Three crystalline modifications and one amorphous form of sulphathiazole have been characterized using differential scanning calorimetry, X-ray diffraction and infrared spectroscopy. The melting points of polymorphs I, II and III are 201.0°C, 196.5°C and 173.6°C, respectively.
