Biomarkers Of Mild Cognitive Impairment And Alzheimer's Disease, Mark A. Lovell, Bert C. Lynn

Chemistry Faculty Patents

A method for quantifying a neurodegenerative disorder in a patient that includes obtaining a fluid sample from the subject; measuring a protein biomarker complex in said fluid sample and correlating the measurement with mild cognitive impairment or Alzheimer's disease status. The biomarkers include those that comprise at least one of a transthyretin protein and/or a prostaglandin-H2 D-isomerase protein, and at least one second, different protein selected from a transthyretin, prostaglandin-H2 D-isomerase, beta-2-microglobulin, cystatin C, superoxide dismutase [Cu—Zn], plasma retinol-binding protein, phosphatidylethanolamine-binding protein, carbonic anhydrase 2, prostaglandin-H2 D-isomerase, and/or serotransferrin protein.

Precatalysts Useful In Polyolefin Polymerization Reactions, Omofolami Tesileem Ladipo, Richard Eaves, Alexey Zazybin, Sean Parkin

Chemistry Faculty Patents

Compounds are provided that are useful as precatlysts in the polymerization of olefins such as ethylene and propylene. Other compounds are useful as intermediates in the production of such precatalysts.

Trans-Excision-Splicing Ribozyme And Methods Of Use, Stephen M. Testa, Michael A. Bell

Chemistry Faculty Patents

A group I intron-derived ribozyme which binds RNA in trans, excises an internal segment from within the RNA, and splices the remaining 5′ and 3′ ends of the RNA back together (the trans-excision-splicing reaction) is disclosed. The excised segment can be as long as 28 nucleotides, or more, and as little as one nucleotide. The ribozymes of the invention are easily modified to alter their sequence specificity. Such ribozymes represent a new and potentially powerful class of generally adaptable genetic therapeutics.

White Matter Diffusion Alterations In Normal Women At Risk Of Alzheimer's Disease, Charles D. Smith, Himachandra Chebrolu, Anders H. Andersen, David A. Powell, Mark A. Lovell, Shuling Xiong, Brian T. Gold

Increased white matter mean diffusivity and decreased fractional anisotropy (FA) has been observed in subjects diagnosed with mild cognitive impairment (MCI) and Alzheimer's disease (AD). We sought to determine whether similar alterations of white matter occur in normal individuals at risk of AD. Diffusion tensor images were acquired in 42 cognitively normal right-handed women with both a family history of dementia and at least one apolipoprotein E4 allele. These were compared with images from 23 normal women without either AD risk factor. Group analyses were performed using tract-based spatial statistics. Reduced FA was observed in the fronto-occipital and inferior temporal …

Effects Of Uvb-Induced Oxidative Stress On Protein Expression And Specific Protein Oxidation In Normal Human Epithelial Keratinocytes: A Proteomic Approach, Marzia Perluigi, Fabio Di Domenico, Carla Blarzino, Cesira Foppoli, Chiara Cini, Alessandra Giorgi, Caterina Grillo, Federico De Marco, D.

BACKGROUND: The UVB component of solar ultraviolet irradiation is one of the major risk factors for the development of skin cancer in humans. UVB exposure elicits an increased generation of reactive oxygen species (ROS), which are responsible for oxidative damage to proteins, DNA, RNA and lipids. In order to examine the biological impact of UVB irradiation on skin cells, we used a parallel proteomics approach to analyze the protein expression profile and to identify oxidatively modified proteins in normal human epithelial keratinocytes.

RESULTS: The expression levels of fifteen proteins - involved in maintaining the cytoskeleton integrity, removal of damaged proteins …

Methods And Kit For Determination Of Prostacyclin In Plasma, Sylvia Daunert, Michael Poon, Urvee Desai, Sapna K. Deo

Chemistry Faculty Patents

A solid-phase immunoassay for 6-keto-Prostaglandin F_1α, the stable hydrolysis product of prostacyclin (Prostaglandin I₂) is disclosed. Prostacyclin, a potent vasodilator with anti-platelet and anti-proliferative properties is an effective treatment for primary pulmonary hypertension and pulmonary arterial hypertension associated with scleroderma and scleroderma-like syndrome. Levels of 6-keto-Prostaglandin F_1α can be directly correlated with levels of prostacyclin. Therefore, 6-keto-Prostaglandin F_1α has become the indicator of choice to measure prostacyclin levels. The single step immunoassay for 6-keto-Prostaglandin F_1α uses the bioluminescent protein, aequorin as a label. Analyte-label conjugates were constructed by linking the carboxyl group of …
