A 53-year-old man was admitted with cervical and inguinal lymphadenopathy. Computed tomography scans showed mediastinal and paraaortic lymphadenopathy and multiple nodular lesions in the liver. An inguinal lymph node biopsy revealed anaplastic Ki-1-positive lymphoma. Laboratory examination showed blood urea nitrogen 66 mg/dl, creatinine 3.6 mg/dl, uric acid 9.9 mg/dl, serum iron 130 μg/dl, tota...

The propagation rate of a fatigue crack in nodular cast iron, loaded cyclic tension, has been studied situ by X-ray computed tomography and digital volume correlation. semi-elliptical initiated from an asymmetric corner notch evolved to semi-circular shape, initially with higher growth towards one edge the before along front became essentially independent position. phase congruency displacement...

nodular fasciitis of the breast is a rare benign pathology of soft tissue that is a consequence of fibroblastic hyperplasia within breast. it can mimic breast cancer clinically, radiologically, and histopathologically. a-43 year-old female with a painless mass within upper-lateral quadrant of her left breast complained of rapid and progressive growth during previous few days. no evidence of nip...

castleman's disease is an uncommon cause of lymph node enlargement that mostly involves the mediastinum and lung hilum. it is divided into 2 types: localized, which is usually asymptomatic and presents with a mass lesion; and multicentric, which is characterized by chills, anemia, generalized lymphadenopathy and hepatosplenomegaly. an extrathoracic site of involvement is very uncommon, and may ...

The current paper is focussed on the nodular cast iron ASTM 80-55-06 (EN-GJS-600). The individual microstructure was investigated by light and scanning electron microscopy as well as micro-hardness measurements. Stress-controlled fatigue tests were performed at ambient temperature with testing frequencies of f = 5 Hz and f = 150 Hz. The cyclic deformation behaviour was characterised by means of...

Ultra High Cycle fatigue leads to a failure initiated in the bulk material of a material. Some results on the nodular cast iron are presented: initiation occurs from the defects, located at the surface or in the bulk. It has been shown that environment plays a major role that could explain the difference between fatigue lives, for the surface and internal initiation. The influence of the defect...
