A monoclonal antibody, Py, was produced by immunizing mice with a glycoprotein fraction isolated from 3-week-old rat hippocampus. Py antibodies gave strong immunocytochemical staining of the perikarya and dendrites of large neurons in many areas of the rat brain, including the cerebral cortex, hippocampus, cerebellum, brain stem, and olfactory bulb. Immunoelectron microscopy showed the antigen ...

To further delineate specific staining patterns and refine the differential usefulness of cytokeratin (CK) 7/20 staining, we studied multiple ovarian tumors and primary nongynecologic neoplasms likely to metastasize to the ovary. Immunohistochemical analysis with semiquantitative grading to give quartile scores (0-4) was performed on 127 cases. Subsequent analysis indicated that a more informat...

Primary pulmonary lymphoma (PPL) is a rare neoplasm. We report case of 45-year-old men who was admitted to hospital for multiple nodules and masses in both lungs. The contrast enhanced chest CT scans revealed varying sizes right upper middle lobes lower lobes. CT-guided percutaneous transthoracic needle biopsy performed. diagnosis PPL confirmed by histopathological examination Immunohistochemic...

The expression of heparan sulfate proteoglycans (HSPGs) by human glioma cells was examined by biochemical and immunological methods in vitro and in vivo. Chondroitin sulfate was shown to represent the major [3H]glucosamine-labeled glycosaminoglycan synthesized by cultured normal brain cells. However, high-grade glioma-derived cells were shown to express significantly increased quantities of hya...

Fluorescent compounds capable of staining cells selectively without affecting their viability are gaining importance in biology and medicine. Recently, a new family of optical dyes, denoted luminescent conjugated oligothiophenes (LCOs), has emerged as an interesting class of highly emissive molecules for studying various biological phenomena. Properly functionalized LCOs have been utilized for ...

INTRODUCTION Several conditions are considered in differential diagnosis of neonatal cholestasis. Of these the most important is extrahepatic biliary atresia (EHBA), while prompt diagnosis and surgical correction of obstruction can ameliorate clinical symptoms, provides long term survival for about one fourth of patients and serves as an important bridge to transplantation for many others. From...

We report the case of an 80-year-old man who presented with pathologically diagnosed chromophobe renal cell carcinoma composed of eosinophilic cells with partial papillary growth. The patient had a 2.5 cm diameter renal mass incidentally detected by abdominal ultrasound examination. Laparoscopic left partial nephrectomy was performed under a diagnosis of left renal tumor. Histopathology demonst...
