Established electrophoretic techniques for the separation of the lactate dehydrogenase (L.D.H.) isoenzymes of tissues and body fluids, although of value in clinical medicine, are too elaborate for most routine laboratories. A simple method for the separation of these isoenzymes on cellulose acetate and their histochemical staining is described. Spectrophotometric estimations of the total L.D.H....

The periodontal ligament is the tissue that connects teeth to bone. The periodontal ligament is a fascinating tissue from a cell biologist's point of view, and because of its special properties and stem-cell content it has also come into the limelight in emerging fields of regenerative medicine. An increased range of genetically modified mouse models offer new tools for studying molecular mecha...

Dept of Structural Biology, Stanford School of Medicine, Stanford, CA 94305, USA. M any molecules involved in eukaryotic transcription and its control have now been identified, including nucleosomes, polymerases, general transcription factors and the regulatory apparatus. Recent excitement in the field stems, in part, from two findings. First, transcriptional coactivators and corepressors funct...

Medical history is often overlooked as advances keep moving forward. Seldom it that in medicine are truly new, unique ideas, but rather built on ideas have been considered before. Even our latest developments will become or forgotten science and advance.

Endomyocardial fibrosis (EF) is characterized by marked endocardial thickening of the apex and subvalvular apparatus of one or both ventricles. It is considered a primary and chronic form of restrictive cardiomyopathy (the acute form is Löffler’s disease) and is associated with inflammation and hypereosinophilia secondary to chronic processes such as parasite infection or autoimmune disease. We...
