OBJECTIVE One of the indications for the rapidly expanding use of thoracoscopic surgery as an alternative to thoracotomy is the excision of peripheral lung nodules. Nodules judged too small or too far from the pleural surface to be seen or palpated during thoracoscopy must be localized beforehand. The purpose of this study was to evaluate the feasibility and effectiveness of percutaneous placem...

Head on collision of localized waves in cold and dense hadronic matter with and without shear and bulk viscosities is investigated. Non-relativistic dynamics of propagating waves is studied using the hydrodynamics description of the system and suitable equation of state. It will be shown that the localized waves are described by solutions of the Burgers equation. Simulations show that the propa...

The goal of this article is to investigate ultra wideband localization with time difference arrival processing at the anchors. We consider scenarios where anchors are placed very close each other and target be localized around group All target–anchor communications assumed in line-of-sight. Since our analysis shows that symmetries anchors’ placement, respect position, degrade positioning accura...

Hence it excludes proton decay and supersymmetry. The main predictions of a gauge model based on the exceptional simple Lie su-peralgebra mb(3|8) (a localized version of su(3) + su(2) + u(1)) are reviewed.

Results of irradiation-hyperthermia treatment in 11 dogs with naturally occurring hemangiopericytoma were reported. Similarities of canine and human hemangiopericytomas were described. Orthovoltage X-irradiation followed by microwave-induced hyperthermia resulted in a 91% objective response rate. A statistical procedure was given to evaluate quantitatively the clinical behavior of locally invas...

purpose : primary localized amyloidosis of eyelid is a localized type of amyloidosis without evidence of systemic involvement, which is a quite rare clinical condition. here we report a case of primary localized amyloidosis of eyelid. case report : a 40-year-old woman presented with a four-month history of swelling of the left upper eyelid resulting in a mechanical ptosis. the mass had a firm b...

Background: Localized and extensive clinical subtypes of alopecia areata (AA) including alopecia totalis and alopecia universalis differ in genetic and immunologic aspects. Objective: Comparison of epidemiologic aspects of localized and extensive subtypes of AA. Patients and Methods: In a prospective descriptive study, 180 patients suffering from AA attending the skin clinics of Razi Hosp...

Cardiac resynchronization therapy (CRT) offers proven benefit to patients with refractory symptomatic chronic heart failure (New York Heart Association Class III or IV), severe left ventricular (LV) systolic dysfunction (LV ejection fraction <35%), and LV dyssynchrony (QRS width >120 ms). Cardiac resynchronization therapy has the potential to improve survival and functional capacity, reduce hos...

BACKGROUND Myofascial pain is defined as pain that originates from myofascial trigger points in skeletal muscle. It is prevalent in regional musculoskeletal pain syndromes, either alone or in combination with other pain generators. The myofascial pain syndrome is one of the largest groups of under diagnosed and under treated medical problems encountered in clinical practice. Trigger points are ...
