Precise Doppler searches for extrasolar planets find a surfeit of planets with orbital periods of 3–4 days, and no planets with orbital periods less than 3 days. The circumstellar distance, R0, where small grains in a protoplanetary disk reach sublimation temperature (∼ 1500 K) corresponds to a period of∼ 6 days. Interior to R0, turbulent accretion due to magneto-rotational instability may evac...

lipoma is the most common soft tissue tumor but the presence of osseous component within the tumor is quite rare. some studies show that less than 1% of lipomas were ossified. we describe the histological, radiological and diagnostic features of an ossified intramuscular lipoma. to the best of the authors' knowledge, a symptomatic ossified intramuscular lipoma without any cortical erosion and h...

BACKGROUND Immunoglobulin G4 (IgG4) related sclerosing disease (rSD) is a new disease entity, first described in 2001, that involves autoimmune pancreatitis. Considered a systemic disease with lesions described in multiple organ systems, IgG4-rSD that affects the sinonasal region is rare. Our goal was to highlight the sinonasal presentation of this unique disease and to review previously report...

Background: En plaque sphenoid wing meningioma is morphological unique in comparison with other intracranial meningiomas, characterized by a carpet-like usually small soft tissue component which invade the dura and extensively involve the bone specially the sphenoid wing and orbit causing significant hyperostosis. Patients & Methods: A retrospective analysis of the clinical data, neuro-radiolog...

This letter underpins the use of three-dimensional computed tomography (3D-CT) reconstruction as an aid to teach veterinary anatomy. Cases were presented to students in order to observe normal and clinically abnormal patients. The images provided excellent details of relevant structures and could serve as a tool for teaching anatomy. Many sources describe different options to enhance anatomical...
