9 Abstract Many of the time-honored methods for histopathological analysis of tissue sections have been superseded by new histological techniques, immunohistochemistry, or other diagnostic tests. Some of the dyes that were used for generations are no longer available, and chemicals used in some older methods are now considered hazardous. Additionally, the histotechnologists and pathologists fam...

Summa ry The growth of our knowledge of normal and pathological histology has been accelerated by two periods of spectacular technical developments. The first, a t the end of the nineteenth century, produced most of the dye staining methods for sections that are now in use. The second, dating from the 1950's to the present time, has seen the application of electron microscopy, histochemistry an...

Background and Objective: Clinical behavior of basal cell carcinoma (BCC) is known to be different according to histological growth pattern and basosquamous cell carcinomas (BSC) are known with their aggressive behavior and metastatic capacity. In this study, we evaluated bcl-2 and cyclin D1 expressions in BCC and BSC cases comparatively, to explore their predictive value on the aggres...

Mining frequent patterns from large databases plays an essential role in many data mining tasks and has broad applications. Most of the previously proposed methods adopt apriorilike candidate-generation-and-test approaches. However, those methods may encounter serious challenges when mining datasets with prolific patterns and/or long patterns. In this work, we develop a class of novel and effic...

The objective of the investigation was to compare the degree of interobserver agreement in determining the histological grade of uterine endometrial endometrioid adenocarcinoma using the criteria proposed by the three-grade FIGO classification (1988) and the new, two-grade system proposed by Lax et al. (2000). In the FIGO system, the assessment is focused on the amount of solid, non-squamous gr...

Samples from 34 patients were studied both histologically and immunocytochemically by the indirect biotin-avidin peroxidase technique to analyse the distribution of the extracellular matrix components (type IV collagen, fibronectin, types I and III collagens) in dissection of the aorta. Most showed defects in type IV collagen around medial smooth muscle cells. Defects in smooth muscle cell base...

A female's risk at birth of having ovarian tumor sometime in her life is 6-7%. Relative frequency of ovarian tumor is different for western and Asian countries. Two third of ovarian tumors occur in women of reproductive age group. This study was done in Tribhuvan University Teaching Hospital with aim to find out frequency of different histological types of ovarian tumors and their age distribut...

Altered tumour cell glycosylation in relation to cellular heterogeneity in human brain tumours remains relatively unexplored. It has been reported that meningiomas express variability in glycosylation properties; however only limited meningioma subtypes have been studied with lectins histochemistry. The aim of this study was to compare the binding pattern of biotinylated lectins in seven subtyp...
