Abstract: This application describes a novel technology in drug discovery and drug-based imaging/detection: the wrapping technology. This technology is based on identified singularities in the structure of soluble proteins. In contrast with drug-design approaches based on standard structural considerations, the packing of a protein, or more precisely, its dehydron pattern, may be used as a selectivity filter to design small-molecule inhibitors. The wrapping technology described herein is a novel form of rational drug design for avoiding side effects in drug therapy and sharpening the inhibitory impact of drugs on the oncokinome.

Abstract: A fiber is obtainable from or comprises a blend of a propylene based polymer and an ethylene/?-olefin interpolymer characterized by an elastic recovery, Re, in percent at 300 percent strain and 1 cycle and a density, d, in grams/cubic centimeter, wherein the elastic recovery and the density satisfy the following relationship: Re>1481?1629(d). Such interpolymer can also be characterized by other properties. The fibers made therefrom have a relatively high elastic recovery and a relatively low coefficient of friction. The fibers can be cross-linked, if desired. Woven, knitted or non-woven fabrics can be made from such fibers.

Abstract: A sulfate process for producing titania from a titaniferous material (as herein defined) including a step of leaching said titaniferous material with a leachant to form a process solution that includes an acidic solution of titanyl sulfate and iron sulfate, wherein said sulfate process further includes a filtration step comprising filtering said leachant to at least substantially remove titanyl sulfate particles from said leachant prior to supplying said leachant to said leach step.

Abstract: The invention relates to an improved process for controlling the amount of crosslinking in polyolefin based articles such as fibers or films. The invention relates to mixing silane grafted material together with ungrafted material prior to crosslinking. The article can then be formed and cured, optionally with a curing catalyst which can preferably be applied to the surface of a shaped article. The amount of crosslinking will be controlled in part by the level of silane grafting on the grafted silane material as well as the amount of the grafted material in the blend.
