Predicting 3D and 2D surface area of corals from simple field measurements.

The structural architecture of coral reefs is a known predictor of species richness, fish biomass and reef resilience. At a smaller scale, three-dimensional (3D) surface area of corals is a fundamental determinant of physical and biological processes. Quantifying the 3D surface area of corals has applications for a broad range of scientific disciplines, including carbonate production estimates, coral predation studies, and assessments of reef growth.

Anaplastic large cell lymphoma: update of findings.

The problem of anaplastic large cell lymphoma (ALCL) is extensively reviewed by depicting the clinical, pathological and biological characteristics of the four main varieties of ALCL: common, Hodgkin's like/Hodgkin-related, lympho-histiocytic, and giant-cell rich. Special emphasis is given to the differential diagnosis between ALCL Hodgkin like and Hodgkin's disease in the light of possible therapeutical differences.

Malignant sarcomatoid mesothelioma of the pleura: a histological and immunohistological study of a case.

The authors describe the case of a 70 year-old asymptomatic female, who showed nodular pleural growths at an occasional chest roentgenogram. Histological examinations and laboratory findings excluded the possibility of an inflammatory granulomatous process, but they did not allow differentiation between malignant sarcomatoid pleural mesothelioma and malignant fibrous histiocytoma. Only at immunohistochemistry was the differential diagnosis made.

Acute idiopathic interstitial giant cell myocarditis. A histological and immunohistological study of a case.

The Authors report on a case of acute idiopathic giant cell myocarditis, which occurred in a young man without previous history of immunodeficiency or tumours, and displayed a rapidly fatal clinical course. Autoptic examination showed diffuse damage to the myocardium, with myocytolysis, granuloma formation and abundant giant cell reaction. No significant changes were observed in the other organs and systems .
