introduction: this study evaluated the diagnostic value of the dipyridamole induced electrocardiuogram (ecg) cahnges, comparing with myocardial perfusion imaging. materials and methods: 222 patinets were studied with dipyridamole infusion (based on ecg criteria) as well as dipyridamole-myocardial perfusion imaging (mpi). results: abnormal dipyridamole test and abnormal mpi were noted in 11% and...

introduction: hemangiomas are the most frequent benign tumors of the liver and detecting them from metastasis or other malignant hepatic tumors is of outmost importance. 99mtc- rbc scan is highly specific and is the method of choice for this differentiation. this scintigraphy is performed in planar and spect modes. these two procedures are in agreement most of the times, however since spect is ...

        Abstract   Squamous cell carcinoma (SCC) is the most common malignant tumors of oral cavity. The ratio of men to women is about 2: 1. Generally, it   is admitted that 60% of carcinoma of the mandibular gingival are located in the posterior of premolars. Gingiva is one of the less common sites of oral squamous cell carcinoma (OSCC). Due to the variable clinical and behavioral presentatio...

The key prior items of work are the MetiTarski theorem prover (Cambridge) and the RAHD decision procedure (Edinburgh). RAHD1 is a proof procedure for polynomials over the reals, and MetiTarski additionally is tailored for handling special functions such as log, exp, sin and cos. Both systems are well beyond the first prototype stage, and both have already shown world-leading characteristics [1,...

The aim of this study was to investigate the application [18F]FDG PET/CT images-based textural features analysis propose radiomics models able early predict disease progression (PD) and survival outcome in metastatic colorectal cancer (MCC) patients after first adjuvant therapy. For purpose, 52 MCC who underwent [18F]FDGPET/CT during restaging process therapy were analyzed. Follow-up data recor...

radical resection of a pathological lesion along with the preservation of eloquent cerebral tissue is the principle goal of neurosurgery. brain lesions are usually diagnosed by conventional magnetic resonance imaging (mri), but this method is unable to describe the relationship between lesions and neighboring specific white matter (wm) tracts. diffusion tensor tractograghy (dtt) is a new sophis...

introduction: noradrenergic cells in lc participate in the process of cortical activation and behavioral arousal. the evidence suggests that locus ceoruleus (lc) plays an important role in the sleep-wake cycle. the aim of this study was stereological estimation of cavity caused by lesion and assessment of sleep stages after bilateral lesion of the lc. materials and methods: male wistar rats wei...

male guinea pigs show high susceptibility to burkholderia mallei and have been used as animal models in glanders studies. the purpose of our study was to elucidate glanders comparative pathogenesis in guinea pigs. we present here the histological changes and bacterial isolation that develop over time in guinea pigs inoculated intraperitoneally (ip) with two strain of b. mallei. ten male guinea ...
