This study was designed to assess intraobserver and interobserver agreement in the diagnosis of 56 endometrial specimens by five European expert gynecologic pathologists using the WHO classification and to establish which histologic features are significantly associated with each classification category. The seven categories were simple hyperplasia, complex(More)
It is extremely useful in investigations of the central nervous system (CNS) to measure mRNA expression in cells by in situ hybridization. However, this approach is limited by the difficulties of a reliable quantitative evaluation. In the present paper we describe a method for quantifying radioactive hybrids on individual cells by a silver grain count in(More)
Renin-angiotensin-aldosterone and sympathetic nervous systems overactivity play a major role in worsening the extent of heart failure. Attenuation of neurohumoral activation with angiotensin-converting enzyme (ACE) inhibitors and beta-blockers has proven beneficial in congestive heart failure. Because ACE inhibition is a recommended treatment for heart(More)
SUMMARY GAAS, Gene Array Analyzer Software supports multi-user efficient management and suitable analyses of large amounts of gene expression data across replicated experiments. Its management framework handles input data generated by different technologies. A multi-user environment allows each user to store his/her own data visualization scheme, analysis(More)
In the kidney, aging is characterized by the development of structural changes, including glomerulosclerosis and interstitial fibrosis. Transforming growth factor-beta1 (TGF-beta1) is known to play a critical role in the genesis of these alterations in pathologic conditions. The present experiments were designed to test the hypothesis that TGF-beta1 may be(More)
BACKGROUND/AIMS The effect of interferon on the reduction of liver fibrosis is controversial. We aimed to compare semiquantitative methods with a quantitative digital image analysis system to assess liver fibrosis in biopsies from patients with chronic hepatitis and different responses to interferon. METHODS We studied 98 liver biopsies with chronic(More)
Interstitial fibrosis and morphologic changes in kidney glomeruli, the structural effects of many diseases, lead to significant pathologic alterations. A reliable and objective method to accurately quantify the extent of interstitial fibrosis and the degree of alteration in glomerular morphology is needed for both clinical practice and experimental work.(More)
BACKGROUND/AIMS Liver fibrosis is one of the most important and characteristic histologic alterations in progressive and chronic liver diseases. Thus, in both clinical and experimental practice, it is fundamental to have a reliable and objective method for its precise quantification. Several semi-quantitative scoring systems have been described. All are(More)
Statistical and clustering analyses of gene expression results from high-density microarray experiments produce lists of hundreds of genes regulated differentially, or with particular expression profiles, in the conditions under study. Independent of the microarray platforms and analysis methods used, these lists must be biologically interpreted to gain a(More)
This paper presents a low cost software platform prototype supporting health care personnel in retrieving patient referral multimedia data. These information are centralized in a server machine and structured by using a flexible eXtensible Markup Language (XML) Bio-Image Referral Database (BIRD). Data are distributed on demand to requesting client in an(More)
