Mucocele of the Appendix: Dilemmas in Differential Diagnosis and Therapeutic Management.

Mucocele of the appendix (AM) is a descriptive term for mucinous distension of the appendiceal lumen. It refers to the progressive retrograde dilatation of the vermiform appendix. Because of a lack of specific signs or due to its sometime quiet presentation, this condition is frequently diagnosed only at an advanced stage.

Karyotyping of yeast strains of several genera by field inversion gel electrophoresis.

Field inversion gel electrophoresis has been used to improve the resolution of the large chromosomes (greater than 1000 kb) present in Saccharomyces kluyveri and in several genera of yeasts other than Saccharomyces cerevisiae, and thus establish more accurately the electrophoretic karyotype of these yeasts. Field inversion gel electrophoresis has also been used to demonstrate the presence of chromosome length polymorphisms in several of the yeasts studied. By Southern blotting techniques the greater degree of relatedness of S.
