Sensitivity and specificity of ex vivo dermatoscopy: a case series.

Background: Sensitivity and specificity of ex vivo dermatoscopy (EVD) for malignancy detection of skin tumors is unknown. We sought to assess whether the use of EVD could be a useful adjunct to histopathological diagnosis of pigmented skin tumors, including cases where complete clinical information is inadequate or missing.

Materials And Methods: EVD was performed on 195 excised, formalin-fixed pigmented skin tumors.

Tissue kidney injury molecule-1 expression in the prediction of renal function for several years after kidney biopsy.

Objectives: Retrospective study was designed to examine the importance of tissue kidney injury molecule-1 (KIM-1) expression in predicting kidney function in sixty patients (27 males) aged 34.15 ± 12.23 years with different kidney diseases over three years after kidney biopsy.

Expression of Bcl-2 and Bax proteins in thyroid glands of rats in experimental thyroiditis.

In the recent years, iodine was associated to the development of apoptosis in thyroid diseases. The aim of the present study is to determine the expression of pro-apoptotic and anti-apoptotic proteins, Bax and Bcl-2, in a Wistar rat experimental model of thyroiditis induced by administration of different doses of potassium iodide. Immunohistochemical staining was done with chromogen diaminobenzidine on avidin-biotin peroxidase using the Animal Research Kit (ARK), stained with antibodies to Bcl-2 and Bax proteins.

Primary non-hodgkin lymphoma of urinary bladder with nine years later renal involvement and absence of systemic lymphoma: a case report.

Aims: Primary bladder non-Hodgkin lymphoma (PBNHL) is very rare, especially as extranodal B-small lymphocytic lymphoma (B-SLL). Also, late isolated renal manifestation of PBNHL is extremely unusual. We report a very rare type of extranodal B-SLL of bladder wall with extremely unusual late isolated renal involvement, clinically manifested by nephrotic syndrome and incipient renal failure.

[HIV infection and the kidneys (Part II): Morphologic changes and their diagnostic significance].

HIV-infected patients may be faced with a variety of renal problem patterns. HIV-associated nephropathy is a unique pattern of sclerosing glomerulopathy and represents the most rapidly progressive form of focal segmental glomerulosclerosis. This study involved the examination of 32 renal biopsies: by light, immunofluorescence, and electron microscopy, in order to determine the most accurate and reliable diagnostic procedure.

[IgA nephropathy: clinico-morphologic correlations].

IgA nephropathy is glomerular disease characterized by the presence of IgA dominant or codominant immunoglobuline deposits in glomerular mesangium which can be demonstrated by immunofluorescence. Clinical manifestations of IgA nephropathy in the majority of cases is hematuria which can be macro or microscopic, isolated or combined with proteinuria, which can be of nephrotic range. The prognosis of the disease is better if presented with haematuria.

[Adhesion molecules in Wilm's tumor: expression and significance of beta-catenin (part II)].

Beta-catenin is a glicoprotein which has an important role in cell-cell adhesion, as well as in cell signal transmission, in u regulation of gen expression and in interaction with axin and APC (adenomatous poliposis coli). Its oncogenic role in several types of carcinomas in human population is well known. It is very likely that beta-catenin as an protooncogen plays an important role in genesis of Wilms tumor.

[Adhesion molecules in Wilm's tumor (part I)].

Adhesion molecules are glicoprotees which have extracellular, transmembranous and intracytoplasmatic part. They show their basic role is in cell interaction in the tissue on one side and between cells and matrix on the other side. They have an important role in stabile integrity of tumor tissue, as well as in differentiation, proliferation, apoptosis and metastatic spread of tumorous cells.

Steric Control of the Electronic Ground State in Six-Coordinate Copper(II) Complexes.

Replacing the 3- and 3''-protons of the ligand 2,6-di(pyrazol-1-yl)pyridine L by mesityl groups changes the electronic ground state of [Cu(L) ] complexes from {d x 2-y 2} to {d z 2} . This is the best example so far for a "homoleptic" Jahn-Teller-compressed six-coordinate Cu complex.
