A novel conductive DNA-based nanomaterial, DNA-peptide wire, composed of a DNA core and a peripheral peptide layer, is presented. The electrical conductivity of the wire is found to be at least three orders in magnitude higher than that of native double-stranded DNA (dsDNA). High conductivity of the wires along with a better resistance to mechanical deformations caused by interactions between t...

Eosinophilic enteritis is a rare disease of unknown etiology. It is characterized by eosinophilic infiltration of the bowel wall to a variable depth and symptoms associated with gastrointestinal tract depending upon the predominant layer involved. Diagnosis of eosinophilic enteritis requires a high index of suspicion and exclusion of various disorders that are associated with peripheral eosinop...

The expression of cell adhesion molecule CD44s was analyzed immunohistochemically in 20 odontogenic lesions. CD44s was detected in almost all the cells on the cell membrane in basal and parabasal cells of the odontogenic cystic lining of the dentigerous cysts and the radicular cysts sparing the superficial layer of the cystic lining. CD44s was expressed on the cell membrane of the peripheral co...

Bone marrow stroma contains multi-potential non-hematopoietic progenitor cells capable of differentiating into various tissues of mesenchymal origin, including osteoblasts, endothelial cells, reticular cells, fibroblasts and adipocytes. The bone marrow's microvasculature with a single layer endothelium forms sinusoid, which radically distributes around the draining central sinus. The vasculatur...

Blood flow in a narrow tube is described using the two-layered model in presence of an external uniform magnetic field. The model consists of a core region, enriched with various types of blood cells and a cell-free peripheral plasma layer. Also the constant heat flux convective heat transfer to fully developed blood flow is studied. The velocity and temperature profiles are determined. The exp...

Dextran sulfate 500 (DS) is known to be a potent B-cell mitogen. Injection of this compound (500 micrograms) into the footpads of mice produced characteristic changes in the draining popliteal lymph nodes, including elimination of macrophages from the lymphatic sinuses and lining the subcapsular sinus, a marked blast reaction throughout the nodal parenchyma, damage to the stroma of the outer pe...

there is considerable agreement among linguists that thematic analysis offers writers insights into manuscripts that may be rejected by international journals due to thematic organization problems. whereas many comparative studies have provided valuable information about thematic progression (tp), the role of peripheral themes (pts) has almost been neglected. using the revised model of the tp p...

the effect of nerve growth factor (ngf) on regeneration of rat sciatic nerves in adult rat was studied. the sciatic nerve was cut out across a 6‑mm gap, then the proximal and distal stumps were inserted into the silicone tube chamber. 7s ngf was extracted from submaxillary gland and then was injected into the silicone in experimental group. after seven months nerve was transected and stained wi...

background: the aim of this study was to evaluate the impact of diabetes mellitus (dm) on peripheral vascular disease (pvd) in patients with coronary artery disease (cad). methods: a total of 13702 consecutive patients who underwent coronary artery bypass grafting (cabg) at tehran heart center between january 2002 and march 2007 were included in this study. the demographic data, pvd, and outcom...

there are extensive evidences that show axonal processes of the nervous system (peripheral and/or central) may be degenerated after nerve injuries. wallerian degeneration and chromatolysis are the most conspicuous phenomena that occur in response to injuries. in this research, the effects of post-operative time following sciatic nerve crush on the number of spinal motoneurons were investigated....
