Heterogeneous Ziegler-Natta and homogeneous metallocene catalysts exhibit greatly different active sitenature in olefin polymerization. In our previous study, it was reported that MgCl2-supported titanocenecatalysts can generate both Ziegler-Natta-type and metallocene-type active sites according to the type of activators.The dual active site nature of the supported titanocene catalysts was furt...

Translocation of precursor proteins from the cytosol into mitochondria is a multi-step process. The generation of translocation intermediates, i.e. the reversible accumulation of precursors at distinct stages of their import pathway into mitochondria ('translocation arrest'), has allowed the experimental characterization of distinct functional steps of protein import. These steps include: ATP-d...

The presence of an unoccupied surface state resonantly coupled to the π* affinity levels precursors, spatially localized in regions where precursors are adsorbed, produces 100% yield photogeneration nonacenes.

This legal research aims to examine the aspect ratio of instruments relating pharmaceutical precursors as they relate rejuvenation efforts; while at same time reviewing based on perspective effectiveness regulation precursors. The results this study state that legislative can be seen from three approaches, namely philosophical, juridical, and sociological. On philosophical aspect, 1945 Constitu...

Finding ways to enhance remyelination is a major challenge in treating demyelinating diseases. Recent studies have suggested that circulating bone marrow cells can home in brain and transdifferentiate into neural cells. To ask whether hematopoietic precursors can form myelinating cells, we investigated the neuropoietic potential of embryonic precursors sorted from the mouse aorta-gonads-mesonep...

discovery of 13c nmr and its application in the biosynthetic pathways prompted the synthesis of several 13c labelled precursors. to investigate the metabolism of phenyllactic acid in the solanaceae family, the double labelled acid was synthesized from barium carbonate (13c) and sodium syanide (13c)

We review monoclonal B-cell lymphocytosis (MBL) as a precursor to chronic lymphocytic leukemia and monoclonal gammopathy of undetermined significance (MGUS) as a precursor to plasma cell disorders. These conditions are present in the general population and increase with age. These precursors aggregate with lymphoproliferative malignancies in families suggesting shared inheritance. MBL and MGUS ...
