Cellular reprogramming and inherited peripheral neuropathies: perspectives and challenges

引用

Neural Regeneration Research 2015年第6期10卷 894-896页

作者： mario A.Saporta Department of Neurology Universidade Federal Fluminense

Inherited peripheral neuropathies （or Charcot-Marie-Tooth disease, CMT） are a phenotypically and genetically heterogeneous group of disorders, which are currently untreatable. They are the most common inherited neuromuscular disorder, affecting around 1 in every 2,500 people （over 120,000 people in the US）. Based on clinical neurophysiological and histopathological features, inherited neuropathies can be divided into two major forms： demyelinating （type 1） and axonal （type 2） CMT （Saporta, 2014）.

Characteristics of Trays Using Inertial Separation Technology

引用

Chinese Journal of Chemical Engineering 2010年第6期18卷 954-961页

作者： YANG Quan Giuseppe Mosca mario Roza Sulzer Chemtech 10 Benoi Sector 629845 Singapore Sulzer Chemtech Sulzer-Allee 48 P.O. Box 65 Winterthur 8404 Switzerland

Though they look very different,UOP SimulFlowTM,Koch-Glitsch Ultra-FracTM,Jaeger CoFloTM and Shell ConSepTM trays fall into the same category of trays using inertial separation technology. However,flooding mechanisms and the trends of entrainment and efficiency are different due to their different working principles. This paper provides a detailed analysis of these trays using available information from literature and U.S. Patents. Efforts are also made to interpret the observations reported. In terms of tray efficiency,it is found that SimulFlow,Ultra-Frac and CoFlo trays are typical point efficiency devices due to a completely mixed liquid pool on the tray deck,while ConSep trays can take advantage of liquid concentration gradient on the tray deck,which makes this tray at-tractive among all ultra high capacity trays.
