M elanocytic nevi, commonly referred to as moles, are very common in children, and the overwhelming majority of melanocytic nevi in children are benign. Given the increased general awareness of melanoma, however, caregivers often express concerns about the development or appearance of their child’s moles. An understanding of the more common types of melanocytic nevi seen in children and of the ...

AIMS To assess the role of Ki67 immunoreactivity in predicting the clinical progress of hydatidiform mole. METHODS Tissue from 87 hydatidiform moles, 11 normal first trimester placentas, 11 normal term placentas and 17 spontaneous abortions were examined for expression of Ki67 antigen, using the monoclonal antibody MIB1. RESULTS Ki67 immunoreactivity was significantly higher in the tissue f...

Streptomyces antibioticus synthesizes a mixture of actinomycins (I to V), each of which possesses 2 moles of n-valine per mole of antibiotic (1, 2) ; occasionally a sixth substance is produced in trace amounts. Streptomyces chrysomallus, on the other hand, forms a mixture consisting of actinomycins IV (containing 2 moles of n-valine), VI (containing 1 mole of n-valine and 1 mole of n-alloisoleu...

The sudden change in appearance of a mole (a dermatologist may call it a nevus or nevi, if there are more than one) or a recent uptick in their quantity can certainly provoke anxiety. Luckily, most types of moles are harmless. While some change in the appearance and number may occur over time, if and when the moles in question exhibit signs of concern that?s the time to seek medical attention (...

The binding of conjugated bile salts to pancreatic colipase and lipase has been studied by equilibrium dialysis and gel filtration. The results indicate that at physiological ionic strength and pH, conjugated bile salts bind as micelles to colipase: 12-15 moles/mole of colipase for the dihydroxy conjugates and 2-4 for the trihydroxy conjugates. No binding of bile salt takes place from monomeric...

BACKGROUND The melanoma incidence has increased over recent decades. Educational campaigns aim to encourage protection from the sun and early detection of melanoma. METHODS During a campaign in Switzerland, information on risk factors, sun protection and melanoma prevention was distributed. 10987 people completed a questionnaire regarding risk factors, and 2746 people were examined by a derma...
