INTRODUCTION Pseudo-Meigs' syndrome is associated with tumors different from the benign ovary tumor, but it has never been described in association to transitional cell carcinoma. CASE REPORT A female 73 year-old patient presenting pleural effusion nonmetastatic associated with renal pelvis transitional cell carcinoma that resolved and did not recur after radical nephroureterectomy. COMMENT...
BACKGROUND The anatomic-electrophysiological correlation of AV nodal reentry is unclear. To localize reentrant circuits during atrial and ventricular echoes and to characterize sites of slow conduction and block, we correlated histology with electrophysiology of the AV node. METHODS AND RESULTS In 10 isolated dog hearts, extracellular electrical activity was recorded in Koch's triangle at 208...
In this report, we describe the identification and characterization of an early embryoid body-derived colony, termed the transitional colony, which contains cell populations undergoing the commitment of mesoderm to the hematopoietic and endothelial lineages. Analysis of individual transitional colonies indicated that they express Brachyury as well as flk-1, SCL/tal-1, GATA-1, (beta)H1 and (beta...
Phosphotungstic acid at low pH and colloidal iron hydroxide have been used to stain sialic acid residues at the surfaces of the transitional epithelium that covers the human urinary bladder. The staining of surfaces of normal epithelium was compared in the electron microscope to staining of surfaces of cells from noninvasive Grade I transitional cell carcinomas and from higher grades of invasiv...
Rac1 and Rac2 GTPases transduce signals from multiple receptors leading to cell migration, adhesion, proliferation, and survival. In the absence of Rac1 and Rac2, B cell development is arrested at an IgD- transitional B cell stage that we term transitional type 0 (T0). We show that T0 cells cannot enter the white pulp of the spleen until they mature into the T1 and T2 stages, and that this entr...
Identifying cross-species similarities and differences in immune development and function is critical for maximizing the translational potential of animal models. Coexpression of CD21 and CD24 distinguishes transitional and mature B cell subsets in mice. In this study, we validate these markers for identifying analogous subsets in humans and use them to compare the nonmemory B cell pools in mic...
We report a case of simultaneous contralateral renal transitional cell carcinoma and renal cell carcinoma. A 63-yr-old male presented with hematuria. He was diagnosed with left renal pelvis tumor and contralateral renal cell carcinoma. Subsequently, the patient received left nephrectomy and paraaortic lymphadenectomy (transitional cell carcinoma, pT3N2M0). Post-operatively, chemotherapy of rena...
