introduction: to compare the efficacy and cost-effectiveness of femtosecond laser versus mechanical microkeratome corneal flap creation in correction of refractive errors. methods: i this review, a comprehensive search of medline, scopus, cochrane, trip database, supplemented by hta and economic databases was performed. we searched for randomized controlled trials (rcts) of femtosecond laser wh...

polycrystalline mfi zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 k. the synthesized zeolite membranes were characterized by xrd, sem and single gas permeation. the influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. mfi zeolite membrane prepared by four subsequent hydrothermal trea...

the simultaneous flow of oil and water in porous media is described by relative permeability curves, mainly derived from laboratory experiments. relative permeability is of paramount importance in predicting reservoir production performance and drive mechanisms and its value depends largely on the volume fraction of fluids present in the test samples. nowadays x-ray scanners are one of the most...

preparation and characterization of thermoresponsive in-situ forming poloxamer hydrogel for controlled release of nile red-loaded solid lipid nanoparticles. nanoparticles (nps) are cleared rapidly from systemic circulation and do not provide sustained action in most cases. to solve this problem, this investigation introduces an erodible in-situ forming gel system as potential vehicles for prolo...

nloaded ection of circulating tumor cells (CTC) is advancing as an effective predictor of patient outcome and eutic response. Unfortunately, our knowledge of CTC biology remains limited, and the impact of treatments on CTC metastatic potential is currently unclear. Improved CTC imaging in vivo and is of free-floating tumor cells now show that cytoskeletal regulation in CTCs contrasts starkly wi...

While previous studies have identified FeMes2(SciOPP) as the active catalyst species in iron-SciOPP catalyzed Kumada cross-coupling of mesitylmagnesium bromide and primary alkyl halides, the active catalyst species in cross-couplings with phenyl nucleophiles, where low valent iron species might be prevalent due to accessible reductive elimination pathways, remains undefined. In the present stud...

MicroRNA (miRNA) regulation is highly cell-type specific. It is sensitive to both the miRNA-mRNA relative abundance and the competitive endogenous RNA (ceRNA) effect. However, almost all existing miRNA target prediction methods neglected the influence of the cellular environment when analyzing miRNA regulation effects. In this study, we proposed a method, MIROR (miRNA Occupancy Rate predictor),...

Machine learning systems have recently received increased attention for their broad applications in several fields. In this study, we show for the first time that histological types of breast tumors can be classified using subtle morphological differences of microenvironmental myoepithelial cell nuclei without any direct information about neoplastic tumor cells. We quantitatively measured 11661...
