Basic principles for interpretation of cytologic preparations

Anatomic Pathology / COMPARISON OF FIVE MELANOMA MARKERS IN CYTOLOGIC PREPARATIONS

We determined the sensitivity and specificity of 3 novel antibodies (microphthalmia transcription factor [Mitf], Melan-A, and tyrosinase) as markers for melanoma in cytologic preparations and compared the results with those of commonly used markers (S-100 protein [S-100] and HMB-45). We stained 72 cell blocks from 40 patients with melanoma and 32 with nonmelanocytic malignant neoplasms with ant...

RODINGITIZATION OF IRANIAN BASIC ROCKS: A NEW INTERPRETATION

Mineral paragenesis of rodingitized basic rocks of Iranian ophiolites are presented and metasomatic reactions between Ca+2 bearing aqueous fluids issued during serpentinization of host ultramafic rock – with magmatic minerals of basic rocks leading to present paragenesis of rodingites are discussed. It is concluded that Ca+2 rich aqueous fluid in equilibrium with serpentinite has high Ca+2 chem...

Basic Principles for Learning Environments

The introduction of new media technology for learning and teaching is frequently linked to hopes for “better” learning. However, previous experience has shown that many of these expectations regarding the “optimisation” of learning are doomed to be disappointing. Virtual worlds are showing quite a different trend: They are viewed with great scepticism as regards their use for teaching and learn...
