Introduction: One of the markers that change due to deoxyribonucleic acid (DNA) damage and the production of free radicals in the poly (ADP-ribose) Polymerase-1 (PARP-1) gene, which plays an essential role in inflammation, apoptosis, and necrosis. This study aimed to evaluate the effect of eight weeks of high-intensity interval training on cardiac PARP-1 gene expression in methamphetaminedepend...

Background: During intensity modulated radiation therapy (IMRT) technique, theoretically, presence of flattening filter (FF) across the beamline of clinical linear accelerator (linac) is not essential to obtain uniform lateral profiles due to intensity modulation of photon beams by multileaf collimators (MLCs). The aim of this study was to investigate the dosimetrical properties of 18 MV photon...
A real-time display system has been designed and tested for use with a radiation field monitor. The system uses only pulse and waveform generators, a multiplexer, and an oscilloscope. The display consists of either a three-dimensional representation of the field intensity distribution or a series of simultaneous profiles.
High-intensity focused ultrasound (HIFU) is a minimally invasive medical procedure which has shown considerable potential for a variety of therapeu tic applications. Some of the medical applications of HIFU include thermal ablation of tumors and uterine fibroids, vessel cauterization, thrombolysis, drug delivery, and gene activation (Curra and Crum [1]). HIFU ablation, unlike other minimally i...
Concentrated high intensity electric field (CHIEF) is non-thermal pasteurization technology that uses microsecond pulses of electricity to inactivate bacteria without causing undesirable changes in flavor or quality of a product. This technology was explored as an alternative to current milk pasteurization processes, and was examined for its effects on microbial stability, sensory, quality and ...
