BACKGROUND Ablation lesion depth caused by radiofrequency-based renal denervation (RDN) was limited to <4 mm in previous animal studies, suggesting that radiofrequency-RDN cannot ablate a substantial percentage of renal sympathetic nerves. We aimed to define the true lesion depth achieved with radiofrequency-RDN using a fine sectioning method and to investigate biophysical parameters that could...

a case of pheochromocytoma of the bladder is presented with a r eview of the literature. we discuss general management principles of bladder pheochromocytoma. successful diagnosis and treatment of this lesion requires a high index of suspicion based upon the patient&apos;s symptom complex, allowing preoperative preparation prior to surgical treatment.

background: marjolin&apos;s ulcer is a rare, aggressive condition that arises on chronic skin lesions and diseases. in this article, we will report 83 cases of this disease. methods: retrospectively, we retrieved 83 records of patients with cancer arising from chronic skin conditions. data concerning demography, type of original skin insult, time interval between original lesion and cancer, can...

central nervous system involvement arising from schistosomiasis is uncommon. it may be produced most fre­quently by schistosoma japonicum infection, but reports of s. mansoni presenting as an intracerebral mass lesion are particularly rare. the authors describe the case of a 35-year-old woman with a 3-month history of partial epilep­tic seizures and head­aches. she immigrated to egypt 4 years a...

Characterization of high-intensity focused ultrasound (HIFU) systems using ex vivo tissues is an important part of the preclinical testing for new HIFU devices. In ex vivo characterization, the lesion volume produced by the absorption of HIFU energy is quantified as operational parameters are varied. This paper examines the three methods used for lesion-volume quantification: histology, magneti...

introduction: the claustrum interconnects with the allocortical and neocortical regions and also projects to the hippocampus and the amygdala. .the role of claustrum in the complex partial seizure is not clear. thus in this study the effect of amygdala lesion on anterior claustrum kindled seizures in rat were investigated. methods: male wistar rats, weighting 250-300 g, were received dc current...

purpose: to report a rare malignant melanoma with chalazion-like presentation.  case report: a 36-year old woman with a chalazion-like mass in the left upper lid, having been resected twice, was referred to our center for the management of recurrence. the total resection of the suspicious area was done. histopathologic examination confirmed the diagnosis of malignant melanoma. the appropriate r...

aim : the purpose of this study was to assess the incidence of 16bp insertion of intron 3 p53 in gastritis lesion and its correlation with clinicopathological aspects. background : p53 alterations have been implicated in the development of gastric malignancies. patients and methods : 97 gastritis and normal adjacent tissues were investigated for p53 gene analysis using pcr-sequencing of intron3...

background: limited data available about the mechanisms of dysphagia and areas involving swallow after brain damage; accordingly it is hard to predict which cases are more likely to develop swallowing dysfunction based on the neuroimaging. the aim of this study was to investigate the relationship between brain lesions and dysphagia in a sample of acute conscious stroke patients. materials and m...

objective(s): there are many reports about the role of rostral ventromedial medulla (rvm) in modulating stress-induced analgesia (sia). in the previous study we demonstrated that temporal inactivation of rvm by lidocaine potentiated stress-induced analgesia. in this study, we investigated the effect of permanent lesion of the rvm on sia by using formalin test as a model of acute inflammatory pa...
