Objective(s) Diabetes related dysfunction of resistance vessels is associated with vascular occlusive diseases. Vasorelaxant agents may have a role in control of diabetic cardiovascular complications. Gamma aminobutyric acid (GABA) has demonstrated to cause vasorelaxation. The present study was designed to determine i) the vasorelaxatory effect of GABA on diabetic vessels and ii) the role of e...

generaly pressure vessels should withstand internal and external pressures in the form of static or periodic stresses. if the application of such a vessel requires the lowest possible weight, the fracture mechanics approach may be considened in design procedure in order to obtain the minimum wall thickness. in this work the thickness of the vessel wall was determined using k values and smallest...

plantlets grown in conventional tissue culture systems usually encounter physiological and anatomical abnormalities including inability to photosynthesize, low chlorophyll content, open stomata, lack of a cuticle layer in the leaf, abnormal xylem parenchyma etc. photoautotrophic and photomixotrophic systems could diminish these problems. the purpose of this study was to increase the chlorophyll...

background: paraoxonase-1(pon1), a high-density lipoprotein (hdl) associated enzyme, is believed to contribute in the patho­genesis of coronary artery disease (cad). the aim of this study was to evaluate the association of pon1 promoter c (-107)t polymorphism with the extent of coronary artery stenosis in iranian patients. methods : the rflp analysis for determination of the c(-107)t genotype d...

Objectives- To provide a reference anatomy of the thoracic cavity vessels of the Rayini goat by using Computed tomography. Design- Experimented study. Animals- Five healthy Rayini goat. Procedures- Spiral CT images (with and without contrast media) were acquired from the thoracic region perpendicular to long axis of the body. CT windows were adjusted as necessary to have optimized images of ...
