Susceptibility-weighted imaging (SWI) has continued to develop into a powerful clinical tool to visualize venous structures and iron in the brain and to study diverse pathologic conditions. It is a new art which evaluates and exploits the properties of blood, iron and other tissues. It is a magnitude or filtered phase images or combination of both, obtained with high-resolution 3D fully velocit...

The study of naturally occurring turbulent flows requires ability to collect empirical data down the fine scales. While hotwire anemometry offers such ability, open field studies are uncommon due cumbersome calibration procedure and operational requirements anemometry, e.g., constant ambient properties steady flow conditions. combo probe-the combined sonic-hotfilm anemometer developed tested ov...

introduction: the purpose of the present study was to determine the effect of 17% ethylene,di-amine, tetra-acetic acid (edta), 6% phosphoric acid and erbium: yttrium, aluminum, garnet (er:yag) laser in removing the smear layer by scanning electron microscopy. methods: in this study, 80 single-rooted human teeth were selected. instrumentation was done by use of hand files and step-back technique...

background: the female breast is subjected to a lifetime of hormonal controls, whose effect is evident at the time of menarche and during the menstrual cycle, pregnancy and lactation. studies have reported multiple risk factors for breast cancer, some of which are a reflection of hormonally mediated events. the steroid receptors are also served as prognostic factors for evaluating status of mal...

background :many breast cancer tumor suppressor genes have been reported to undergo hypermethylation, including er, rassf1a, hic, cdh1, gspt1, apc, twist and ccnd2. we first determined the promoter methylation of the above eight tumor suppressor genes as epigenetic markers of breast cancer in three cell lines with different er status. methods : this study was an experimental study performed on ...

Recent results from CLEO on B → Kπ indicate that the phase γ may be substantially different from that obtained from other fit to the KM matrix elements in the Standard Model. We show that γ extracted usingB → Kπ, ππ is sensitive to new physics occurring at loop level. It provides a powerful method to probe new physics in electroweak penguin interactions. Using effects due to anomalous gauge cou...
