We previously reported that patients with a clinical complete response (CR) following radiofrequency thermal treatment exhibit significantly increased body temperature compared with other groups, whereas patients with a clinical partial response or stable disease depended on the absence or presence of output limiting symptoms. The aim of this study was to evaluate the correlation among treatmen...
OBJECTIVE This paper describes the successful treatment of two patients with chronic fatigue syndrome (CFS) using repeated thermal therapy. METHODS Two patients with CFS underwent treatment with prednisolone (PSL), with no satisfactory effect. They were subjected to thermal therapy that consisted of a far-infrared ray dry sauna at 60 degrees C and postsauna warming. The therapy was performed ...
The aim of this research is to analyze the efficacy of radiofrequency ablation (RFA) for varying electrothermal parameters. An attempt has been made to study the RFA for the effect of thermal conductivity, electrical conductivity and blood perfusion rate with Taguchi’s design of experiments methodology. Their combined effect was analyzed quantitatively in different tissues. It was found that ab...
high‑intensity focused ultrasound (hifu) is a novel treatment modality used by scientists and clinicians in the recent decades. this modality has had a great and significant success as a noninvasive surgery technique applicable in tissue ablation therapy and cancer treatment. in this study, radio frequency (rf) ultrasound signals were acquired and registered in three stages of before, during, a...
OBJECTIVES Thermal pulsation (LipiFlow) has been advocated for meibomian gland dysfunction (MGD) treatment and was found useful. We aimed to evaluate the efficacy and safety of thermal pulsation in Asian patients with different grades of meibomian gland loss. METHODS A hospital-based interventional study comparing thermal pulsation to warm compresses for MGD treatment. Fifty patients were rec...
لوله گرمایی وسیله ای برای انتقال حرارت با ضریب هدایت گرمایی خیلی بالا می باشد که انرژی گرمایی را به وسیله تبخیر و میعان یک سیال عامل با افت دمای ناچیز منتقل می کند. هنگامی که گرما به اواپراتور می رسد سیال عامل تبخیر می شود و یک گرادیان فشار در لوله ایجاد می کند. این گرادیان فشار باعث می شود بخار در طول لوله حرکت کند تا به کندانسور برسد. در کندانسور بخار میعان شده، گرمای نهای تبخیر آن آزاد می شو...
تنش های پسماند جوشی بواسطه اعمال حرارت موضعی در حین فرآیند جوشکاری در اتصالات جوشی به وجود به وجود می آیند. این تنش ها با توجه به بارگذاری های خارجی می توانند کارکرد سازه را تحت تاثیر قرار دهند. علاوه بر این تنش های پسماند می تواند عامل تغییر شکل های جوشی نیز بشود که این مورد در مونتاژ قطعات مشکل ساز است. بنابراین در سازه ی جوشکاری شده جهت آزاد نمودن تنش های پسماند عملیات حرارتی تنش گیری انجام ...
BACKGROUND This study was performed to assess the photothermal response of highly focused laser energy using infrared thermal imaging instrument to detect and assess the actual temperature distribution during flash lamp pumped pulsed dye laser (FLPPDL) treatment for port wine stain (PWS) patients and avoiding its complications. METHODS A retrospective review of 40 patients with PWS birthmark ...
The field of focal ablative therapy for the treatment of cancer is characterized by abundance of thermal ablative techniques that provide a minimally invasive treatment option in selected tumors. However, the unselective destruction inflicted by thermal ablation modalities can result in damage to vital structures in the vicinity of the tumor. Furthermore, the efficacy of thermal ablation intens...
