1. An enzymatic assay for microsomal acyl-CoA: cholesterol acyltransferase (ACAT) activity in chicken hepatic tissues was developed using silicic acid chromatography. 2. ACAT activity was increased in response to liver cytosolic protein preparations suggesting the presence of cytosolic modulators of the enzyme. 3. Fractions containing low molecular weight(More)
An unusual appearing gingival amalgam pigmentation (amalgam tattoo) that completely surrounded the maxillary right first premolar in a 13-year-old boy is presented. Because of the wide distribution and apparent clinical progression of the discoloration, an excisional biopsy was performed. The histopathologic diagnosis of amalgam pigmentation was confirmed(More)
This paper explores combining functional modeling and biomimetic design. Observed benefits of applying functional modeling to biomimetic design include a more complete, systematic modeling that reveals additional aspects of biological phenomena to be exploited. Incorporating biological phenomena into a function-based design repository requires that multiple(More)
The neurotropic melanoma is a rare and highly malignant variant of melanoma that possesses a biphasic neoplastic component. A lentigo maligna melanoma commonly precedes a downgrowth of spindle cells that exhibit fascicle formation and striking neurotropism. A strong predilection for occurrence on the lip has been indicated by published reports. Difficulties(More)
Two cases have been presented in which a malignant lymphocytic tumor was found in the oral soft tissues. The first was a "histiocytic lymphoma" that appeared as a rapidly growing, ulcerative lesion. This tumor was the initial presentation of disease and may be considered a primary lesion. The second was a "poorly differentiated lymphocytic lymphoma" which(More)
