conclusions our study revealed that patients with the diagnosis of breast cancer have greater bpe in comparison with control group. the results may be indicative for higher probability of developing breast cancer in patients with higher bpe. therefore, ce-mri could be a useful tool for breast cancer risk assessment. objectives background parenchymal enhancement (bpe) on contrast-enhanced magnet...

conclusions this method could be feasibly used for purification of large quantities of allicin from garlic extract. results semi-preparative hplc yielded a distinct peak with a retention time of 12.28 minutes. the purity (≥ 95%) and biological activity (p > 0.05) of purified allicin were comparable to the standard allicin. purified allicin produced same peak areas compared to the standard allic...

As worldwide demand of hydrocarbon is growing fast, the oil and gas companies have been forced to explore reservoirs with more hostile conditions, such as high-pressure, high-temperature conditions. Improved technology, material selection and testing procedures are required to overcome the common problems in these conditions. One of the main phases of well construction is cementing job. Appropr...

introduction abnormal neural impulses in the nervous system may lead to various diseases and disabilities. high frequency alternating currents (hfac) has been used to block the propagation of such impulses and improve the symptoms or disabilities. the technique is safe, reversible, and relatively selective, and its reliability, the optimum stimulation parameters, and elimination of the onset re...

in the present study, a comprehensive and systematic strategy was described to evaluate the performance of several three-way calibration methods on a bio-analytical problem. parallel factor analysis (parafac), alternating trilinear decomposition (atld), self-weighted alternating trilinear decomposition (swatld), alternating penalty trilinear decomposition (aptld) and unfolded partial least squa...
