Introduction: Astrocyte dysfunction is the common pathology resulting in failure of astrocyte-neuron interaction in neurological diseases, including Parkinson’s Disease (PD). To date, only few experimental models of selective ablation of astrocytes are known. The aim of present study was to evaluate the effect of striatal injections of selective glial toxin L-aminoadipic acid (L-AA) on the loco...

Introduction: Thermal ablation by microwave (MWA) has proven efficacy in treatment of primary and metastatic cancers. Soft tissue tumors could be ablated completely using MWA. However, bony tissue metastasis particularly spinal vertebral metastasis ablation has not reported yet. Case presentation: A 50 year old male patient with primary diagnosed colon cancer undergone surgical resection of ...

conclusions we can conclude that treatment of af using a right-sided minithoracotomy approach and rf energy in patients undergoing cardiac surgery for various valve diseases is feasible, safe, and reproducible. objectives our aim is to evaluate the feasibility, safety, and immediate plus medium-term results of concomitant af ablation therapy in patients undergoing minimally invasive valve surge...

although the basic question of ablative threshold dose for ablation of thyroid remnant after surgery yet remains unanswered. but radioiodine therapy is being used as a standard method of treatment. in present research, treatment responces for 100 patients with thyroid cancer treated with 3660 mbq of ¹³¹i were studied. significant response differences between female group (66%) and male group (3...

Introduction: Halitosis and foreign body sensation are two common and disturbing symptoms of chronic caseous tonsillitis (CCT). The aim of this study was to compare the efficacy and safety of temperature-controlled radiofrequency (TC-RF) tonsil ablation with CO2-laser cryptolysis (CO2-LC) in the treatment of patients with halitosis caused by CCT.   Materials and Methods: Sixty-two patients who ...

background: radiofrequency catheter ablation (rfca) has been introduced as the treatment of choice for supraventricular tachycardia. the aim of this study was to evaluate the success rate as well as procedural and in-hospital complications of rfca for the treatment of atrioventricular nodal reentrant tachycardia (avnrt).   methods: between march 1995 and february 2009, 544 patients (75.9 % fema...

purpose: to compare visual outcomes and changes in high-order aberrations (hoas) following conventional versus customized photorefractive keratectomy (prk). methods: in this clinical trial, 58 eyes of 29 patients underwent myopic prk using the technolas 217z excimer machine. after comprehensive evaluation for refractive surgery, one eye of each participant randomly received conventional ablatio...

accessory pathways (ap) are abnormal myocardial connections between atria and ventricles with electrical conductive properties. we performed radio frequency (rf) catheter ablation in 66 patients with manifest ap at dr.shariati hospital during 5 years. bipolar mapping was used in 48 patients and unipolar mapping in 18 patients of find the best site for rf energy delivery. we calculated total dur...

The aim of this study was to investigate the therapeutic efficacy of percutaneous radiofrequency (RF) ablation versus microwave (MW) ablation for hepatocellular carcinoma (HCC) measuring ≤ 5 cm in greatest diameter. From January 2006 to December 2006, 78 patients had undergone RF ablation whereas 77 had undergone MW ablation. Complete ablation (CA), local tumour progression (LTP) and distant re...
