The external diameters of rat and rabbit basilar arteries were determined before and after formaldehyde fixation in relaxed and drug constricted vessels. Fixation usually resulted in an immediate vessel constriction followed by partial relaxation after several hours. However, the results were inconstant from vessel to vessel and from area to area of the same vessel. It is concluded that morphol...
Ductal carcinoma in situ (DCIS) is an established precursor of invasive breast carcinoma. Immunoperoxidase stains for selected markers can assist pathologists in the diagnosis of challenging ductal epithelial proliferations, but they cannot replace morphologic evaluation as the primary and critical assessment of this disease. Molecular studies provide further insight into how DCIS progresses to...
PURPOSE Positron emission tomography (PET) with [(18)F]fluorodeoxyglucose (FDG) is increasingly used in early assessment of tumor response after chemotherapy. We investigated whether a change in [(18)F]FDG uptake at 2 days of gefitinib treatment predicts outcome in patients with lung adenocarcinoma. EXPERIMENTAL DESIGN Twenty patients were enrolled. [(18)F]FDG-PET/computed tomographic (CT) sc...
Adrenal cortical carcinoma is a rare but interesting endocrine tumor. Its diagnosis is usually straightforward using morphologic assessment and supplemental immunohistochemistry. However, diagnostically challenging cases exist and pathologic evaluation would benefit from the availability of adjunctive molecular testing. Here, the relevant molecular pathology of adrenal cortical tumors is review...
objective: to study plants purification capability of cu on two cultivars of vetch plant (vigna radiata) in contaminated soils and their effects on morphological characteristics. methods: we conducted a completely randomized trial as factorial. different concentrations of cu (0, 150, 300, and 400 mg/ kg of dried soil) were used. after four weeks growth on contaminated soil, parameters such as...
