patients with valvular heart disease and suffering atrial fibrillation of more than 12 months duration have a low probability of remaining in sinus rhythm after valve surgery alone. we performed intra-operative radiofrequency ablation or cryoablation as an alternative to surgical maze ііі procedure to create linear lesion lines for conversion of this arrhythmia to sinus rhythm. a total of 30 pa...

Photoacoustic imaging systems offer a platform with high resolution to explore body tissues, food, and artwork. On the other hand, plasmonics constitutes source of resonant heating thermal expansion generate acoustic waves. However, its associated techniques are seriously limited laser penetration nonspecific hyperthermia in sample. To address this issue, present work adopts paradigm shift phot...

The temperature-independent effects of electromagnetic fields (EMF) have been controversial for decades. Here, we critically analyze the available literature on non-thermal radiofrequency (RF) and microwave EMF. We present a review preclinical clinical data antiproliferative various EMF applications, including conventional RF hyperthermia (HT, cRF-HT). Further, suggest evaluate plausible biophy...

Abstract We elaborated a technique of pulsed laser ablation in gas mixtures (He-N 2 ), maintained under residual pressures 0.5–5 Torr to deposit silicon (Si)-based nanostructured films on substrate. show that the deposited can exhibit strong photoluminescence (PL) emission with position peaks depending pressure ambient and ratio gases mixture. Nanostructured prepared pure He exhibited band infr...

Low-field magnetic resonance imaging (MRI) has become increasingly popular due to cost reduction, artifact minimization, use for interventional radiology, and a better safety profile. The different applications of low-field systems are particularly wide (muscle–skeletal, cardiac, neuro, small animals, food science, as hybrid scanner hyperthermia, in radiology radiotherapy). scanners produce low...

Serotonin is believed as an important factor in brain function. The role of serotonin in cerebral psycho-patho-physiology has already been well established. However, the function of serotonin antagonist in anesthetized subjects under hyperthermia has not been studied properly. Methods: Experiments were performed in three groups of urethane-anesthetized rats, such as: (i) control group, (ii) wh...

Introduction:  The  success  of  hyperthermia  depends  on  the  accuracy  of  the  temperature  monitoring in the tumor and the surrounding normal tissue. In this study, the temperature changes  were determined by computing the speckle displacement in the ultrasound digital images. Speckle  tracking algorithm was used to compute the displacement.  Materials and Methods: The experiment was perf...

background: a possible mechanism by which hyperthermia enhances tumor immunogenicity is the induction of nkg2d ligands on tumor cells. although the expression of mhc class i chain-related protein a and b (mica/b) has previously been reported in different carcinomas, there is no information about mica/b expression in liposarcomas. objective: to investigate mica/b induction in a human liposarcoma...
