It is well established that many viruses produce inclusion bodies in the nucleus or cytoplasm of an affected cell, and that the morphological appearance of such inclusions may be pathognomonic of a particular infection (Pinkerton, 1950). Similar bodies may also result from the toxic action of certain heavy metals (Lee, 1933; Blackman, 1936; Olitsky and Harford, 1937). They are occasionally foun...

Recent empirical research found that the strong short-term relationship between monetary aggregates and US real output and inflation, as outlined in the classical study by M. Friedman and Schwartz, mostly disappeared since the early 1980s. In the light of the B. Friedman and Kuttner (1992) information value approach, we reevaluate the vanishing relationship between US monetary aggregates and th...

introduction:neurogenic mediastinal tumors comprise a wide range of benign and malignant diseases. a group of these tumors, located at thoracic apex, sometimes spread to cervical spaces causing numerous surgical difficulties. in thoracotomy approaches, due to proximity of the tumors to major blood vessels, complete removal of these tumors from cervical spaces is impossible or may cause intraope...

introduction: different imaging modalities are used to evaluate salivary gland diseases, including tumors. ultrasonography (us) is the preferred method on account of its ease of use, affordability, safety profile, and good tolerance among patients. the aim of this study was to evaluate the role of us in differentiating malignant from benign parotid tumors, in the context of previous controversy...
