the authors describe a case of histiocyte-rich b-cell lymphoma (hr-bcl), a variant of diffuse large b-cell lymphoma, in a 51-year-old man. the patient presented with large axillary lymphadenopathy. histopathologic and immunohistochemical examination of lymph node biopsy revealed diffuse effacement of the lymph node architecture by reactive histiocytes and neoplastic cd20 positive b cells. react...

background: the aim of this study was to quantify the number of mast cells in focal reactive hyperplastic lesions of the oral cavity and to compare these two number of mast cells in normal gingival tissues and to correlate their presence with the state of connective tissue changes in reactive lesions and probably suggest a role for mast cells in these lesions. materials and methods: patient rec...

background: reactive lesions of the oral cavity are non-neoplastic proliferations with very similar clinical appearance to benign neoplastic proliferation. this similarity is troublesome in the differential diagnosis. the aim of this study was to determine the frequency and distribution of oral cavity reactive lesions. materials and methods: the study was a retrospective archive review. the med...

programmed cell death is a highly regulated form of cell death, mostly distinguished by the activation of a family of cystein-aspartate proteases (caspases) that cleave various proteins resulting in morphological and biochemical changes characteristic of this form of cell death. several recent studies have addressed the role of programmed cell death in inflammatory and chronic pain states. casp...

Isolated rat hepatocytes in culture were incubated with different concentrations of iron-sorbitol (50, 100, 150, and 200 µM) to assess the changes in reactive oxygen species (ROS) and lipid peroxidation leading to apoptotic hepatocyte cell death. The viability of hepatocytes was declined depending on the iron concentration. One hour incubation of the cells with 100 µM iron resulted in decreased...

background: lung carcinoma is a multiple type cancer comprising of small cell and non-small cell carcinomas (nsclc). for therapeutic and diagnostic purposes, serum monoclonal antibodies have been produced against lung cancer. objective: to charac-terize a murine monoclonal antibody (me3d11) reactive with human nsclc. methods: a murine monoclonal antibody (me3d11) reactive with human nsclc was s...
