OBJECTIVE To determine the predominant histopathological patterns seen in the testicular biopsies taken during the investigation of male infertility and to compare the obtained histopathological findings with those seen in other similar studies. METHODS This is a retrospective study performed on 230 testicular biopsies which were examined in the Department of Pathology at King Khalid Universi...

Anticipation describes an inheritance pattern within a pedigree with an increase in disease severity or decrease in age at onset or both in successive generations. The phenomenon of anticipation has recently been shown to be correlated with the expansion of trinucleotide repeat sequences in different disorders. We have studied differences of age at onset and disease severity between two generat...

results long-term exposure to lead acetate caused histopathology effects including dilatation, congestion, nuclei heterochromatic effects, increase in diameter of renal tubules and urinary barrier thickness in rabbit renal tissue. conclusions quantitative and qualitative results of long-term lead acetate exposure showed many histopathology side-effects, especially in the urinary barrier. materi...

OBJECTIVE To determine the association and correlation between morphologic features of breast cancer on gray scale ultrasound, and vascularity patterns and indices on color and spectral Doppler ultrasound. STUDY DESIGN Cross-sectional, analytical study. PLACE AND DURATION OF STUDY Department of Radiology, Dow University of Health Sciences and Civil Hospital, Karachi, from August 2006 to Jun...

The problem of morphologic variation in pneumococcus has been reviewed and the desirability of studying such variation through an examination of bacterial cells rather than of bacterial colonies has been pointed out. To further this objective, a new terminology to describe the morphologic variants of pneumococcus, potentially applicable to other bacterial species, has been proposed. A hitherto ...

The program deduces morphologic elements in contexts formed by not necessarily segmented in words iterative infinite sentences. Experiments with small contexts prove that in them morphologic units’ form varies. The program does not use morphologic information extracted from databases, which allows analyzing multilingual contexts.

Background: Pleomorphic adenoma (PA) is a benign salivary gland tumour with high incidence and recurrence after treatment. It may recur the same appearance or develop toward malignancy, namely as carcinoma ex pleomorphic (CXPA). Howthis can transform into CXPA remains unclear. Purpose: The aim of this study was to analyse possibility pathogenesis progressivity PA CXPA. Methods: Twenty-four samp...
