patients and methods twenty-two young men (age = 23.34 ± 2.56 years, weight = 72.47 ± 12.01 kg, and height = 174.10 ± 5.75 cm) were recruited and randomly assigned into control (n = 10) and hiit (n = 12) groups. echocardiography was used to evaluate left ventricular mass (lvm), end-systolic volume (esv), end-diastolic volume (edv), interventricular septal wall thickness (ivswt), stroke volume, ...

background: high intensity interval training (hiit) is a novel training method which has received most attention in recent years. the aim of this study was to examine the effect of 8 weeks of high intensity interval training (hiit) on plasma levels of adiponectin and leptin in overweight nurses. m aterials and methods: 27 nurses (mean age 25.81±60 years, height 158.01±67 cm and weight 69.41±25 ...

objective(s):high-intensity interval training (hiit) increases energy expenditure and mechanical energy efficiency. although both uncoupling proteins (ucps) and endothelial nitric oxide synthase (enos) affect the mechanical efficiency and antioxidant capacity, their effects are inverse. the aim of this study was to determine whether the alterations of cardiac ucp2, ucp3, and enos mrna expressio...

background: the aim of this study was to investigate the effects of high-intensity interval training (hiit) on nitric oxide metabolites (no2 - , no3 - ) and myocardial infarct size after ischemia/reperfusion (i/r) injury in healthy male rats. methods: a total of 44 wistar rats were randomly divided into 4 groups including hiit (n=8), hiit + ir protocol (n=14), control (n=8), and control + ir (n...

Background/introduction Anti-tumor immune response caused by High Intensity Focused Ultrasound (HIFU) therapy has been a subject of controversy. Most agree that the response is more likely to be induced by mechanical, rather than thermal effects of HIFU. The goal of the current work was to study the effect of HIFU-induced liquefaction of a tumor on tumor-specific and non-specific T-cell mediate...

Introduction Ultrasound is widely applied in the clinical field today, such as ultrasound contrast agent imaging, High Intensity Focused Ultrasound (HIFU), Extracorporeal Lithotripsy, sonodynamic therapy. Some of these have a close relation to the dynamic behavior of micro bubbles and that of a bubble cloud. In an ultrasound imaging, micro bubbles are used as contrast agents. Extracorporeal Foc...

A new approach for characterizing high intensity focused ultrasound (HIFU) transducers is presented. The technique is based upon the acoustic streaming field generated by absorption of the HIFU beam in a liquid medium. The streaming field is quantified using digital particle image velocimetry, and a numerical algorithm is employed to compute the acoustic intensity field giving rise to the obser...

Laser-enhanced cavitation during high intensity focused ultrasound (HIFU) was studied in vivo using a small animal model. Laser light was employed to illuminate the sample concurrently with HIFU radiation. The resulting cavitation was detected with a passive cavitation detector. The in vivo measurements were made under different combinations of HIFU treatment depths, laser wavelengths, and HIFU...
