PURPOSE In cases of thyroid toxic autonomous nodule, anterior projection of Tc-99m pertechnetate image shows a hot nodule that occupies most, or the entire thyroid lobe with near-total or total suppression of the contra lateral lobe. In this case is very difficult to distinguish toxic nodule from lobe agenesis. Our interest was to estimate and determinate the rate of radioactivity when the sour...

A concept is a mental representation that encompasses multiple aspects of an item, but what is the neurological substrate of this representation? One hypothesis states that such representations depend upon multimodal binding processes within a single region. Convergent evidence suggests that such a region may exist within the temporal lobe(see Patterson 2007). To test these hypotheses we utiliz...

In a previous study, we have shown that passive recognition of tactile geometrical shapes (i.e. no exploratory movement) engages prefrontal and premotor areas in addition to somatosensory regions (Savini et al., 2010). In the present study we tested the hypothesis that these regions are involved not only in the perception but also during working memory of such somatic information. We performed ...

a 40-year-old male patient presented to us with complaints of pain in abdomen for the past 2 weeks and fever for 3 days. the patient gave history of being previously operated for hydatid cyst of liver 15 years back. his chest radiograph and com-puted tomography scan revealed a cystic lesion in the right lobe of liver and a cyst in left lung. the patient was managed surgically. aspirate from the...

In the presence of main lobe jamming, performance modern radar system would degrade significantly. this study, a blind source separation (BSS) method based on an Adaptive Opposite Fireworks Algorithm (AOFWA) is proposed to address problem ineffective target echo detection when subjected jamming. First, signal model for BSS applied in anti-main jamming provided, and number signals estimated. The...
