background: the interaction between the blood and the vessel wall is of great clinical interest in studying cardiovascular diseases, the major causes of death in developed countries. objective: to understand the effects of incorporating fluid-structure interaction into the simulation of blood flow through an anatomically realistic model of abdominal aorta and renal arteries reconstructed from c...

BACKGROUND To clarify various conditions in the transplanted kidney, invasive biopsy must be performed in most cases. In this study, we measured blood flow in the transplanted kidney by color Doppler tomography to examine the usefulness of measuring renal blood flow in clarifying various conditions. METHOD Blood flow in the transplanted kidney was measured using peak flow velocity (PFV) and a...

Objective(s): Considering the lack of information, the effects of mild endurance exercise plus blood flow restriction (BFR) on electrocardiographic parameters, hypertrophy index, and expression of angiotensin II receptors type 1 (AT1R) and type 2 (AT2R) and apelin receptor (APJ) were assessed in hearts of old male rats.Materials and Methods: Animal were grouped as control (CTL), Sham (Sh), lowe...

to study the effect of herb ginger powder on performance, carcass characteristics and blood parameters of broilers used from 192 broiler chicks (ross ) in a completely randomized design with 4 treatments and 4 replicates ( each replicate of 12 chicks ). all treatments, including different levels of ginger powder ratios of 0, 0.5, 1, 1.5 percent respectively called t1, 2t, t3 and t4 that were ad...

background: pulse wave velocity (pwv) is widely used for estimating the stiffness of an artery. v arious invasive and non-invasive methods have been developed to determine pwv over the years. in the present research , the non-invasive estimation of the pwv of large arteries was used as an index for arterial stiffness. methods: a dynamic model based on the navier-stokes equations coupled to elas...

adenosine has many of the characteristics of a regulator of cerebral blood flow and adenosine receptors change in morphine dependency. in this study the changes in adenosine receptors' responsiveness of pial vessels in the hind limb area of the sensory cortex were evaluated in morphine dependent rats (mdr) using the laser doppler flowmetry technique. adult male sprague dawley rats (250-350...

BACKGROUND Diabetes mellitus (DM) is one of the most common diseases worldwide. Uncontrolled and prolonged hyperglycemia can cause diabetic complications, which reduce the quality of life of patients. Diabetic complications are common in DM patients. Because it is impossible to completely recover from diabetic complications, it is important for early detection. In this study, we suggest a novel...

AIMS/BACKGROUND To investigate the reproducibility and potential diurnal variation of choroidal blood flow parameters in healthy subjects over a period of 12 hours. METHODS The choroidal blood flow parameters of 16 healthy non-smoking subjects were measured at five time points during the day (8:00, 11:00, 14:00, 17:00, and 20:00). Outcome parameters were pulsatile ocular blood flow as assesse...
