Photonic technologies have received considerable attention regarding the enhancement of radiofrequency electrical systems, including high-frequency analogue signal transmission, control of phased arrays, analog-to-digital conversion and signal processing. Although the potential of radiofrequency photonics for the implementation of tunable electrical filters over broad radiofrequency bandwidths ...

BACKGROUND Radiofrequency surgery is a method of utilizing high frequency (3.8 to 4MHz) radio wave energy to incise, excise, or coagulate tissues. Radiofrequency (RF) is a relatively new modality that is being used for ano-rectal surgeries with increasing frequency. As the RF energy is applied, frictional heating of tissues results, with cell death occurring at temperatures between 60 and 100 d...

BACKGROUND The lethal isotherm for radiofrequency catheter ablation of cardiac myocardium is widely accepted to be 50°C, but this has not been directly measured. The purpose of this study was to directly measure the tissue temperature at the edge of radiofrequency lesions in real time using infrared thermal imaging. METHODS AND RESULTS Fifteen radiofrequency lesions of 6 to 240 seconds in dur...

Background: Drug resistance is widely believed to be an increasingly serious threat to global public health. We have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. In our previous studies, Klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-e...

BACKGROUND Pulsed radiofrequency treatment has recently been described as a non-neurodestructive or minimally neurodestructive alternative to radiofrequency heat lesions. In clinical practice long-lasting results of pulsed radiofrequency treatment adjacent to the cervical dorsal root ganglion for the management of chronic radicular spinal pain have been reported without neurologic complications...

In the microwave-radiofrequency spectrum, Wi-Fi is a short-range wireless broadband technology, which transmits at frequency of 2.5 GHz. This type technology has been positioned itself as one most widely used technological advances in recent years. It reported that direct exposition to radiofrequencies can induce physiological changes different animals and plants species. One degenerative effec...

Wireless communications play a crucial role in human lives. The introduction of cellular network systems, broadband internet services and public Wi-Fi increase the connectivity between people exponentially. These wireless networks require antenna structures to propagate carrier waves through space these are located within Radiofrequency (RF) region electromagnetic spectrum. effects RF on people...

OBJECTIVE Hyperhidrosis (Hh) and facial blushing (Fb) are conditions caused by hyperactivity of the sympathetic system; they affect around 2% of the population. Severe cases have been typically treated with thoracic sympathectomy through a minimally invasive approach. We sought to determine if severe Hh and/or Fb patients, who are reluctant to go through an operation with general anaesthesia, c...

BACKGROUND Sacroiliac joint pain is a common cause of chronic low back pain. Different techniques for radiofrequency denervation of the sacroiliac joint have been used to treat this condition. However, results have been inconsistent because the variable sensory supply to the sacroiliac joint is difficult to disrupt completely using conventional radiofrequency. Cooled radiofrequency is a novel t...
