چکیده
Fig. 1 Volume rendered transverse images and manual segmentation (magnified) of the free-running Purkinje fiber network in the LV of a young rabbit heart (left) and an old rabbit heart (right). Lines and arrows in the green and red boxes indicate where sectioning occurred and viewer was located. Interseptal thickness is approximately 3.93 mm (young) and 4.82 mm (old). I: ventricular interseptum, P: papillary muscle, FW: free wall

Non-invasive monitoring of changes in rabbit hearts with aging using MR microscocpy
Background Loss of myocytes followed by compensatory hypertrophy of the remaining cells and interstitial fibrosis are common hallmarks observed in aging hearts [1,2]. The cardiac conduction system is also subject to alterations with aging, resulting in reduced thresholds to diseases [3]. Biopsy is an accurate and informative means to delineate the age-related changes. However, it is destructive...
متن کاملMRI evaluation of rabbit bone marrow after acute irradiation
Background: Magnetic Resonance Imaging (MRI) is a safe modality and useful in characterizing normal and abnormal bone marrow (BM). MRI also presents a more global view of BM than biopsy therefore, it may provide a better understanding of hematologic disorders. The purpose of this study was to monitor radiation-induced alterations of BM in acute phase of irradiation (1-10 day after total body ir...
متن کاملLiquid Biopsy as a Minimally Invasive Source of Thyroid Cancer Genetic and Epigenetic Alterations
In the blood of cancer patients, some nucleic acid fragments and tumor cells can be found that make it possible to trace tumor changes through a simple blood test called “liquid biopsy”. The main components of liquid biopsy are fragments of DNA and RNA shed by tumors into the bloodstream and circulate freely( ctDNAs and ctRNAs). tumor cells which are shed into the blood (circulating tumor cells...

The aim of this study was to compare invasive and non-invasive strains of Shigella flexneri isolated from Tehran by a 120 kDa protein band by SDS-PAGE, electron microscopy of cell culture and Congo red dye methods. Methods: S. flexneri strains were isolated by standard bacterial methods from fecal specimens of children attending to the 3 children’s hospitals. Phenotype analysis for screening v...
