Searching For Binding Partners For The Novel Phkg1 Variant, Phkγ 181, Kishore Polireddy Apr 2008

Searching For Binding Partners For The Novel Phkg1 Variant, Phkγ 181, Kishore Polireddy

Student Research Conference Select Presentations

Phopshorylase kinase (PhK) is a hexadecameric holoenzyme made up of four different subunits in the arrangement (αβγδ)4 and has total molecular mass of 1.3MDa. Alpha and β are regulatory subunits, γ is catalytic, and δ is an intrinsic molecule of calmodulin. PhK is a serine threonine kinase with glycogenolytic regulatory functions. Our lab has recently discovered that the γ subunit can be alternatively processed to produce a truncated form of 181 residues (γ-181). This variant of γ contains a phosphorylation site for PK-C, and its activity is influenced by this phosphorylation. We are using a LexA based yeast two hybrid …

Photochemical Studies Of Nutraceuticals In The Presence Of Cyclodextrins, Zlata Tofzikovskaya, Christine O'Connor, Mary Mcnamara Jan 2008

Photochemical Studies Of Nutraceuticals In The Presence Of Cyclodextrins, Zlata Tofzikovskaya, Christine O'Connor, Mary Mcnamara

Conference Papers

The photostability studies of Folic acid and Menadione Sodium Bisulfite, also known as vitamin K3, were carried out in their aqueous solutions at room temperature. Solutions of Folic acid ( 4.8 x 10-5 M) and Menadione Sodium Bisulfite (4.0 x 10-4 M) were exposed to ultraviolet radiation at a wavelength of 365 nm. During exposure absorbance of both solutions was measured using a Perkin Elmer Lamda 900 UV/VIS/NIR Spectrometer. During the stability tests it was noted that addition of β Cyclodextrin (1:1 ratio) to aqueous solutions containing the vitamin slowed down the photodegradation process. The unique shape of Cyclodextrins allows …

Metallopharmaceuticals As Photoactivatable Anticancer Drugs, Samar Moqadasi, Christine O'Connor, Denis O'Shea, Michael Devereux Jun 2007

Metallopharmaceuticals As Photoactivatable Anticancer Drugs, Samar Moqadasi, Christine O'Connor, Denis O'Shea, Michael Devereux

Conference Papers

Target-based research (treating infected site only), directed towards the design and mechanism of action of metal-based anticancer complexes is expanding rapidly due to the selectivity and activity of such novel therapeutics. The photo activation of Ruthenium (II) complexes as therapeutic drugs has recently escalated as the complexes are suitable for photoactivation due to their well published photochemical and photophysical properties which in turn is the basis of photodynamic approaches to therapy.1-5 The aim of this study is to synthesise a series of metallo-complexes of which will be tested on tumour and non-tumour cell lines in the Radiation & Environmental Science …

Activated Carbon Open Circuit Potential Shifts In Aqueous Solutions, Mikhail M. Goldin, Gary Blanchard, Alexander Volkov, Mogely Khubutiya, Vladimir Kolesnikov, Anatoly Evseev, Mark Goldin Jan 2007

Activated Carbon Open Circuit Potential Shifts In Aqueous Solutions, Mikhail M. Goldin, Gary Blanchard, Alexander Volkov, Mogely Khubutiya, Vladimir Kolesnikov, Anatoly Evseev, Mark Goldin

Faculty Publications and Presentations

Interaction of certain organic compounds with activated carbon and its effect on the carbon open circuit potentials were studied. It was shown that shifts in open circuit potentials depended on the filling of the activated carbon surface. Whereas adsorption of the investigated compounds on the carbon led to positive potential shifts, their elimination (desorption) from carbon surface led to shifts in the opposite direction. It was also observed that the time dependence of potential shifts is similar for different carbon brands. The magnitude of shifts depended on adsorption activity and porometric characteristics of the carbon adsorbent, as well as the …

Wind Turbine Project At The University Of Rhode Island, Auriane Koster Apr 2006

Wind Turbine Project At The University Of Rhode Island, Auriane Koster

Senior Honors Projects

In the Fall of 2003, an initiative to develop and install a wind turbine on the University of Rhode Islands Kingston Campus was proposed by an undergraduate student, Courtney Blodgett. To spearhead this initiative, the Renewable Energy Club (REC) was created and recognized by the Student Senate, and support was received by the URI Offices of the President and Provost. The University recognized the benefits of investing in a wind turbine both in terms of money spent on energy costs, and in promoting research in renewable energy. Turbines are at the cutting edge of technology. This is the first such …

Landscape Patterns Of Streams & Lakes In Montane Watersheds Determine Water Temperatures & Nutrient Transport: Watershed Analyses And N Tracer Experiments, Wayne A. Wurtsbaugh, J. Garrett, G. Burkart, W. Fleenor, K. Nydick, R. Hall, Michelle A. Baker Jan 2005

Landscape Patterns Of Streams & Lakes In Montane Watersheds Determine Water Temperatures & Nutrient Transport: Watershed Analyses And N Tracer Experiments, Wayne A. Wurtsbaugh, J. Garrett, G. Burkart, W. Fleenor, K. Nydick, R. Hall, Michelle A. Baker

Watershed Sciences Faculty Publications

In glaciated mountains, lakes are interspersed through watersheds and connected by streams. Although lakes or streams are frequently studied as individual water bodies, studying them as integrated functional units provides considerable insight on temperature patterns, nutrient transport and other functions. In the Sawtooth Mountains (Idaho), inter-lake distance averages 2.8 km. In summer, lakes are solar collectors, and warm outflow streams as much as 10 C, thus increasing metabolic rates. These streams seldom cool to equilibrium temperatures before encountering another lake, where the waters tend to overflow and mix into the epilimnion. With overflow, N-15 tracer experiments demonstrated that water and …
