In the arid areas of river itself, direction flow is characterized by changes depending on its hydrological regime. As a result these changes, can be branched into several streams and distributed differently in terms quantity. passes through lightly washed soils, have different depths, hydraulic elements morphometry vary at intensities. Changes resistance as such affect water permeability strea...

background: for a long time, intestinal parasite infections are among the major problems of public health in iran. our aim was epidemiological studies on the frequency of intestinal parasites in patients re­ferred to three hospitals in tehran during 2007-2008. methods : during 2007-2008, by simple random selection, 1000 stool samples were collected from mi­lad, hazrat-e-rasoul and shahid fahmid...

subulura brumpti infection was observed in japanese quails and caused heavy production loss up to 10%. gross lesions were confined to caecum of the affected birds. pathological changes suggestive of acute cecal hemorrhagic enteritis were recorded. closer observation of the cecal loop revealed wavy movement with thousands of tiny worms. based on morphometry, the worms were identified as s. brump...

Background: The hippocampus and corpus callosum have been shown to be vulnerable in head injury. Various neuroimaging modalities and quantitative measurement techniques have been employed to investigate pathological changes in these structures. Cognitive and behavioural deficiencies have also been well documented in head injury. Aims: The aim of this research project was to investigate structur...

Multisubject statistical analyses of diffusion tensor images in regions of specific white matter tracts have commonly measured only the mean value of a scalar invariant such as the fractional anisotropy (FA), ignoring the spatial variation of FA along the length of fiber tracts. We propose to instead perform tract-based morphometry (TBM), or the statistical analysis of diffusion MRI data in an ...

This paper presents feature-based morphometry (FBM), a new, fully data-driven technique for identifying group-related differences in volumetric imagery. In contrast to most morphometry methods which assume one-to-one correspondence between all subjects, FBM models images as a collage of distinct, localized image features which may not be present in all subjects. FBM thus explicitly accounts for...

Objectives: Knowledge of the shape and dimensions of the glenoid are important in the design and fitting of glenoid components for total shoulder arthroplasty. An understanding of variations in normal anatomy of the glenoid is essential while evaluating pathological conditions like osseous Bankart lesions and osteochondral defects. Methods: This study was done on 202 dry, unpaired adult human s...

Three different methods to determine intramyocellular lipid (IMCL) contents in human skeletal muscle have been compared. (1)H-magnetic resonance spectroscopy (MRS) was evaluated against electron microscopic morphometry and biochemical assays of biopsy samples from m. tibialis anterior of 10 healthy subjects. The results of (1)H-MRS and morphometry were strongly correlated, proving the validity ...

Intestinal obstruction may be duo to various mechanical or functional reasons. Worms, especially Ascaris worms are one of the mechanical reasons of intestinal obstruction. Obstruction due to Taenia saginata is a rare phenomenon. Here we report a case of intestinal obstruction due to Taenia saginata infection in a 30 year-old male patient undergoing laparatomy with the diagnosis of intestinal ob...
