Introduction: Many radiotracers have been used for sentinel node mapping with acceptable results. The main difference between these radiotracers is the particle size. In the current study, we reported defective labeling of Tc-99m antimony sulfide colloid which resulted in large particle size. Methods: Tc-99m-Antimony sulfide colloid was used for axillary sentinel n...

Objectives: Presence/absence of cervical lymph node metastasis plays a critical role in prognosis and survival of patients with oral squamous cell carcinoma (SCC). This study was designed to assess the diagnostic accuracy of computed tomography (CT) scan for detection of cervical lymph node metastasis in oral SCC in comparison with histopathological analysis after neck dissection Methods: In...

background: the role of diagnostic pathology has become more prominent. this study aimed to compare the accuracy of frozen section compared with permanent section in the morning and afternoon working hours. methods: in this cross-sectional study, 99 patients with stage 1 and 2 breast cancer who underwent sentinel and non-sentinel lymph node biopsy between 2013 and 2015 were included. the result...

to clarify the underlying physiological mechanism of gibberellic acid (ga) in cold tolerance, the effects of exogenous ga3 on malondialdehyde (mda), osmoregulation substances and endogenous hormones levels in the tiller nodes of two wheat cultivars, namely, dongnongdongmai 1 (a cold insensitive cultivar) and jimai 22 (a cold sensitive cultivar), were investigated at three periods of cold winter...

background and objective: fine needle aspiration cytology (fnac) is a well-established method of diagnosis in palpable masses of various sites. this study was conducted to evaluate the usefulness of fnac as a diagnostic tool in the management of patients with cervical lymphadenopathy. patients and methods: totally 178 patients admitted to loghman-hakim hospital , tehran, iran, with cervical mas...

the charts of 27 patients with kawasaki disease (kd) admitted to nemazee hospital in shiraz from january 1991 to october 1998 were reviewed to identify the results of mean peroxidase index (mpxi) values, a measure of neutrophil staining intensity, obtained by the technicon hi analyzer (technicon instruments corp., tarrytown, ny) within the first 10 days of the illness 2 separate groups of patie...

mobile sensor networks rely heavily on inter-sensor connectivity for collection of data. nodes in these networks monitor different regions of an area of interest and collectively present a global overview of some monitored activities or phenomena. a failure of a sensor leads to loss of connectivity and may cause partitioning of the network into disjoint segments. a number of approaches have bee...

introduction: intranodal pathways of atrioventricular (av) node play a vital role in the delay of conduction time in response to various atrial inputs. the present study was aimed to determine the frequency-dependent electrophysiological properties of concealed slow pathway according to a functional model of isolated rabbit atrioventricular node preparation after fast pathway ablation. methods:...
