a total of 1500 infected liver with f. hepatica and f. gigantica from slaughtered cattle in different parts of iran were studied. grossly the livers were usually irregular in shape, with prominent bile ducts on the visceral surface as grayish-white, firm-branching streaks. the atrophy of the left lobe due to fibrosis and ischemia were noticed. on the cut surface the main bile ducts wall consist...

We examine the effect of Dean number on inertial focusing spherical particles suspended in flow through curved microfluidic ducts. Previous modelling particle migration ducts assumed rate was small enough that a leading-order approximation background with respect to produces reasonable model. Herein, we extend our model situations involving moderate (in microfluidics context) while Reynolds rem...

Distal airways are less than 2 mm in diameter, comprising a relatively large cross-sectional area that allows for slower, laminar airflow. The airways include both membranous bronchioles and gas exchange ducts, and have been referred to in the past as the ‘quiet zone’, in part because these structures were felt to contribute little to lung mechanics and in part because they were difficult to st...

symptomatic mullerian duct cysts are uncommon. a young adult male presented to us with a palpable supra-pubic mass, pain and lower urinary tract symptoms. initial imaging modalities showed a large cystic lesion in the pelvis with a non-visualized right kidney. a short, blind ending right ureter on retrograde pyelography added to the confusion. on exploration, the lesion was noted to be separate...

CONTEXT AND OBJECTIVE Breast cancer is thought to derive from progressively aberrant, non-invasive breast lesions, but it is not known exactly how invasive breast cancer develops from these lesions. The aim of this study was to verify the changes in c-erbB-2 and p53 protein expression between non-neoplastic ducts, ductal carcinoma in situ and invasive ductal carcinoma found in the same breast. ...

Background: Fasciolosis is a crucial helminthes disease caused by two trematodes of the genus Fasciola: Fasciola hepatica (temperate liver fluke) and gigantica (tropical fluke). Methods: A cross-sectional study was conducted on cattle sheep in slaughterhouse to detect animals infected with Fasciolosis. Liver samples were collected from transferred laboratory for histopathological immunohistoche...

Background: Fasciola hepatica is a genus of the trematodes which mainly affects the liver of sheep and these livestock are accidentally infected by eating plants or drinking water contaminated with the metacercariae of this parasite. These parasites can cause considerable economic damage by destroying the liver and bile ducts. OBJECTIVES: The aim of this study was to evaluate the role of ultras...

This study is concerned with the numerical analysis, formulation, programming and computation of steady, 3D conservation equations of reacting laminar flow heat and mass transfer in ducts of arbitrary cross-sections. The non-orthogonal boundary-fitted coordinate transformation method is applied to the Cartesian form of overall-continuity, momenta, energy and species-continuity equations, parabo...
