Background: The important of angiogenesis for the progressive growth and viability of solid tumors is well established. Only few data are available for hematologic neoplasms. Materials and Methods: To investigate the role of angiogenesis in the acute myloid leukemia (AML) bone marrow biopsies from 30 adults with newly diagnosed, untreated AML(day 0) were evaluated. Further studies were done aft...
Background& Objective: Micro-vascular proliferation is an important histological feature of brain glioma with more vascular proliferation is present in higher grades of glioma. CD 105 is expressed in new actively proliferating and immature endothelial cells in tumor environment and appears to be capable to distinguish between malignant neo-vasculature and normal vesse...
Introduction: There are few studies investigating the role of neoangiogenesis in biological behavior of salivary gland tumors. CD105 expression has demonstrated greater accuracy for detecting new vessel formation compared with other pan-endothelial molecules. This study aimed to assess and compare intratumoral Micro-Vessel Density (MVD) through using immunohistochemichal expression of CD105 bio...
Background and Objective: This study aimed to evaluate the changes in macular superficial and deep capillary plexus (SCP and DCP) density, Foveal Avascular Zone (FAZ) area, and visual acuity in patients with diabetic macular edema after anti-VEGF therapy. Materials and Methods: This descriptive-analytical study utilized before and after treatment design. In total, 30 eyes of 30 patients with d...
Micro-tomography produces high resolution images of biological structures such as vascular networks. In this paper, we present a new approach for segmenting vascular network into pathological and normal regions from considering their micro-vessel 3D structure only. We consider a partition of the volume obtained by a watershed algorithm based on the distance from the nearest vessel. Each territo...
abstract probiotic products highly affect the health of consumers by reducing the risk of heart attacks and improving of desirable microflora in intestinal tract. in this study the effect of yogurt (500g/d for 3 wk) enriched with either bifidobacterium bifidum or lactobacillus acidophilus on the level of cholesterol, low density lipoprotein (ldl) and high density lipoprotein (hdl) of serum and ...
Background: Pancreatic islet transplantation has emerged as a promising treatment for type I diabetes. However, its efficacy is severely hampered due to poor islet engraftment and revascularization, which have been resulted to partially loss of transplanted islets. It has been shown that local delivery of vascular endothelial growth factor (VEGF) could accelerate transplanted islet revasculari...
background: pancreatic islet transplantation has emerged as a promising treatment for type i diabetes. however, its efficacy is severely hampered due to poor islet engraftment and revascularization, which have been resulted to partially loss of transplanted islets. it has been shown that local delivery of vascular endothelial growth factor (vegf) could accelerate transplanted islet revasculariz...
Steroid-induced osteonecrosis of the femoral head (steroid-induced ONFH) is an avascular necrosis disease of bone. Tetramethylpyrazine (TMP), with significant vascular protective properties, has been widely used for the treatments of ischemic neural disorders and cardiovascular diseases. However, its role in the treatment of steroid-induced ONFH has not been evaluated. In this study, our result...
