concurrent hyperthermia and radiation therapy in treatment of cancer show a strong evidence of a synergistic enhancement. we designed a new self-regulating thermo-brachytherapy seed, which serves as a source of both radiation and heat for concurrent administration of brachytherapy and hyperthermia. the thermo-brachytherapy seed has a core of ferromagnetic material which produces heat when subje...

introduction:amphetamines are central nervous system (cns) stimulant substances and amphetamine abuse is considered a growing problem in our country. previous studies revealed destructive effects of amphetamines on metabolism, perfusion and structure of brain. the aim of current study was evaluating regional cerebral blood flow (rcbf) disturbances in methamphetamine (ma) abusers using brain per...

Sensing technology provides quantitative characterization of blood flow, hydration, perfusion, skin temperature, and thermal transport properties.

background: standard methods for the measurement of myocardial perfusion are invasive and require cardiac catheterization or the use of radioisotope dyes. the coronary sinus blood flow (csbf) is an appropriate criterion for the efficacy of myocardial perfusion. this study sought to measure csbf via transthoracic echocardiography (tte) in patients with acute myocardial infarction (ami) and to as...

We simultaneously assessed the blood flow index (BFI) in three respiratory muscles during hyperpnea and high-intensity constant-load cycling sustained at comparable levels of work breathing neural drive patients with COPD. demonstrated that exercise impairs muscle perfusion, as intercostal, scalene, abdominal BFI increased but not cycling. Insufficient adjustment perfusion was associated greate...

Objective: Measurement of blood-brain permeability dysfunction in active and chronic MS lesions with T1-weighted dynamic contrast-enhanced MRI to show variation in inflammatory activity Background: blood-brain-barrier perfusion characterization impaired in MS as some studies have shown recently buta comparison between perfusion parameters in contrast-enhanced and non-enhanced lesions not have ...

Objective. To observe the dermal microcirculation blood perfusion characterization of meridians channels (acupoints). Methods. 20 healthy human subjects were monitored using Pericam Perfusion Speckle Imager (PSI) for the changes in dermal microcirculation blood perfusion on governor meridian and other respective dermal regions as a control. Result. The microcirculation blood perfusion on Govern...
