Abstract: One aspect of the invention relates to chiral bisoxazolidines and their use in asymmetric catalysis. The chiral bisoxazolidines are a novel class of compounds that is expected to find multiple applications, for example, in asymmetric synthesis. For example, a bisoxazolidine ligand enabled the catalytic enantioselective alkynylation and alkylation of a range of aromatic and aliphatic aldehydes, generating chiral propargylic alcohols and secondary alcohols in high yields and enantiomeric excess.
Abstract: Patients with chronic illnesses resist using conventional automated healthcare management systems to supply necessary clinical data because such systems feel impersonal, preferring to actually visit a clinic where the patient interacts with various healthcare practitioners. In this invention, the patient interacts with a clinical management system via a series of initial GUI screens that replicate the experience of actually visiting the clinic. Additional screens allow the patient to submit clinical information, to communicate with that patient's healthcare practitioner and other healthcare practitioners, to access management information that aids the patient in managing that patient's chronic illness, and to access educational information regarding that chronic illness. The clinical management system may be used to manage a plurality of different chronic illnesses while providing a consistent look and feel to the screens.

Abstract: The present invention relates to the development of a pharmacological non-human animal model that associates memory loss to histopathological features found in the brain of a subject having Alzheimer's Disease. In one embodiment, a four-week continuous infusion of a Fe2+, A?42 and buthionine sulfoximine (FAB) solution in the left ventricle of young adult Long-Evans rats induced memory impairment accompanied by increased hyperphosphorylated Tau protein levels in cerebrospinal fluid. Brains from treated animals displayed neuritic plaques, tangles, neuronal loss, astrogliosis and microgliosis in hippocampus and cortex. The present invention may be utilized in evaluating preventive, therapeutic and diagnostic means for neurologic diseases.

Abstract: This invention relates to the discovery that pleiotrophin binds to and activates a pleiotrophin-receptor which is responsible for the events associated with pleiotrophin activity including tumorigenesis, cell proliferation, and cell invasion. By interfering with that association, the cascade of events associated with pleiotrophin activity can be prevented or reversed. Further, by evaluating the effect of different compounds and conditions on the interaction, new drugs and treatments can be identified for use in preventing certain cancers and growth and developmental disorders.

Abstract: One aspect of the present invention relates to a method for the transition metal (e.g., Cu(I)) mediated amidation of C—H bonds using electron-rich aliphatic azides. In certain embodiments, the methods are useful for the C—H insertion of nitrenes generated and stabilized by a ?-diketiminato metal catalyst. In certain embodiments, said nitrenes are generated from organoazides, or by oxidation of the corresponding amine. Another aspect of the present invention relates to olefin aziridination using said ?-diketiminato metal catalysts. In addition, the methods of the present invention include stereoselective C—H bond aminations and olefin aziridinatons. In certain embodiments, the methods are conducted in an aerobic environment. In certain embodiments, the present invention relates to the use of O2 as an oxidant, wherein water is the byproduct of oxidation; this fact avoids the generation of toxic byproducts and renders the methods atom economical.

Abstract: A separation module operates to fractionate or separate an analyte into fractions according to pI, i.e., pI bands, utilizing capillary isoelectric focusing (“CIEF”) within a first microchannel. The fractions are stacked to form plugs, the number of which is determined by a number of parallel second microchannels integrally connected to the first microchannel, into which the fractions are directed according to the buffer characteristics found in each of the individual microchannels. Within the microchannels the plugs are separated into proteins according to a different chemical property, i.e., “m/z,” utilizing capillary electrophoresis (“CE”).

Abstract: The present invention relates to methods, reagents, and kits for assessing organ damage, such as damage due to ischemia reperfusion injury, in the course of a transplantation therapy and/or for assessing organ regeneration following transplantation therapy. The invention provides a method for determining an index of organ health in the course of transplantation therapy comprising measuring the expression level of peripheral-type benzodiazepine receptor (PBR) in the organ. Measuring the expression level of PBR is also useful for assessing the progress of organ regeneration in the course of transplantation therapy by comparing the index of organ health. The expression level of PBR may be used as a predictor of the outcome of transplantation therapy.
