Biogeographical Distribution And Natural Groupings Among Five Sympatric Wild Cats In Tropical South Asia, Mohammed Ashraf Oct 2007

Biogeographical Distribution And Natural Groupings Among Five Sympatric Wild Cats In Tropical South Asia, Mohammed Ashraf

Mohammed Ashraf

Small to large carnivorous mammals in the tropical belt face extinction at an unprecedented rate. The vanishing of sympatric wild cats appears to be due to habitat fragmentation, human encroachment & poaching. The focus of this study is on ecological and distributional parameters that influence the wild cat communities in tropical South Asia. The distributional data for five sympatric cats is analyzed with the aim of understanding the species-habitat association under a conceptually unified binary-matrix framework. The use of cluster analysis techniques in this ecological study have helped to reveal the natural groupings among felid guilds and their ecological resource …


Meta-Analysis Evidence Of A Differential Risk Of The Fcrl3 -169t->C Polymorphism In White And East Asian Rheumatoid Arthritis Patients, Steven J. Schrodi, Begovich Ann, Chang Monica Jul 2007

Meta-Analysis Evidence Of A Differential Risk Of The Fcrl3 -169t->C Polymorphism In White And East Asian Rheumatoid Arthritis Patients, Steven J. Schrodi, Begovich Ann, Chang Monica

Steven J Schrodi

Association between a functional promoter polymorphism (rs7528684) in the Fc receptor-like gene, FCRL3, and rheumatoid arthritis (RA) has been observed in 3 independent Japanese case-control sample sets ([1][2]). Studies examining the role of this polymorphism in risk of RA in 9 independent white sample sets, however, have yielded conflicting results ([3-8]). Further, a large study of Korean subjects failed to demonstrate association of this single-nucleotide polymorphism (SNP) with RA ([9]). Although the precise function of FCRL3, which has strong structural homology with the classic Fc receptors, is unknown, the existing data are consistent with the hypothesis that it may influence …

Depleted Carbon Monoxide In Fragment C Of The Jupiter-Family Comet 73p/Schwassmann-Wachmann 3, M. A. Disanti, W. M. Anderson, G. L. Villanueva, B. P. Bonev, K. Magee-Sauer, E. L. Gibb, M. J. Mumma May 2007

Depleted Carbon Monoxide In Fragment C Of The Jupiter-Family Comet 73p/Schwassmann-Wachmann 3, M. A. Disanti, W. M. Anderson, G. L. Villanueva, B. P. Bonev, K. Magee-Sauer, E. L. Gibb, M. J. Mumma

Erika Gibb

Carbon monoxide emission was targeted in fragment C of the recently split Jupiter-family comet 73P/Schwassmann-Wachmann 3 during its 2006 apparition, using the Cryogenic Echelle Spectrograph (CSHELL) at the NASA IRTF on Mauna Kea, Hawaii. Simultaneous sounding with H2O near 4.65 μm revealed highly depleted CO, consistent with a mixing ratio of 0.5% ± 0.13%. Along with depleted CH3OH but nearly normal HCN, this may indicate that this comet formed in the inner giant planets' region or, alternatively, that it formed relatively late, after significant clearing of the protosolar nebula.


High-Loading Nanosized Micelles Of Copoly(Styrene-Maleic Acid)-Zinc Protoporphyrin For Targeted Delivery Of A Potent Heme Oxygenase Inhibitor., Arun Iyer Mar 2007

High-Loading Nanosized Micelles Of Copoly(Styrene-Maleic Acid)-Zinc Protoporphyrin For Targeted Delivery Of A Potent Heme Oxygenase Inhibitor., Arun Iyer

Arun Iyer

Amphiphilic styrene-maleic acid (SMA) copolymer efficiently formed micelles with a potent heme oxygenase inhibitor-zinc protoporphyrin (ZnPP). The micelles were constructed by subtle pH adjustments to form non-covalent interaction between the hydrophobic ZnPP and amphiphilic SMA. The micelles (SMA-ZnPP) thus formed were nanoparticles with narrow size distribution in water (mean diameter 176.5nm), having tunable loading (from 15% to 60% w/w of ZnPP) with remarkable aqueous solubility. SMA-ZnPP had an average molecular size of 144kDa as determined by size-exclusion chromatography (SEC), this size is a marked increase from the molecular weight of free ZnPP (626.03Da), suggesting the formation of micellar structure. The …

Computational Modeling Of Calcium Dynamics Near Heterogeneous Release Sites, Borbala Mazzag, Zachary Cooper, Michael Greenwood Dec 2006

Computational Modeling Of Calcium Dynamics Near Heterogeneous Release Sites, Borbala Mazzag, Zachary Cooper, Michael Greenwood

Borbala Mazzag

Background: Calcium is known to play an important role in many physiological
processes, such as egg fertilization and heart muscle functions.
Several recent theoretical studies ([4], [1]) investigated calcium dynamics
near so-called release sites – clusters of calcium-regulated channels on
the intracellular calcium stores. Interest in the synchronized openings of
channels within a release site has increased because these openings are
thought to be the building blocks of global calcium events.
Methods: We conduct computational studies of the effect of heterogeneity
in the make-up of the release site on the resulting calcium dynamics.
We introduce heterogeneity into the model of …

Controlled Language: The Next Big Thing In Translation?, Uwe Muegge Dec 2006

Controlled Language: The Next Big Thing In Translation?, Uwe Muegge

Uwe Muegge

Many global organizations are beginning to see the productivity indicators for their translation and localization processes reach a plateau. That’s an inevitable fact even for those organizations that use what’s currently billed as the latest and greatest in translation technology, such as translation memory with automated workflow components or globalization management systems. Even with these tools in place, making content available in multiple languages remains a very expensive and time-consuming proposition. For those looking for ways to reduce the cost of translation to the point where almost all materials that should be translation actually can be translated, controlled language may …


In The Heat Of The Law, It's Not Just Steam: Geothermal Resources And The Impact On Thermophile Biodiversity, Donald J. Kochan, Tiffany Grant Dec 2006

In The Heat Of The Law, It's Not Just Steam: Geothermal Resources And The Impact On Thermophile Biodiversity, Donald J. Kochan, Tiffany Grant

Donald J. Kochan

Significant research has been conducted into the utilization of geothermal resources as a ‘green’ energy source. However, minimal research has been conducted into geothermal resource utilization and depletion impacts on thermophile biodiversity. Thermophiles are organisms which have adapted over millions of year to extreme temperature and chemical compositions and exist in hot springs and other geothermal resources. Their ability to withstand high temperatures makes them invaluable to scientific and medical research. Current federal and California case law classify geothermal resources as a mineral, not a water resource. Acquisition of rights to develop a geothermal resource owned or reserved by the …


Finding Molecular Complexes Through Multiple Layer Clustering Of Protein Interaction Networks, Bill Andreopoulos, Aijun An, Xiangji Huang, Xiaogang Wang Dec 2006

Finding Molecular Complexes Through Multiple Layer Clustering Of Protein Interaction Networks, Bill Andreopoulos, Aijun An, Xiangji Huang, Xiaogang Wang

William B. Andreopoulos

Clustering protein-protein interaction networks (PINs) helps to identify complexes that guide the cell machinery. Clustering algorithms often create a flat clustering, without considering the layered structure of PINs. We propose the MULIC clustering algorithm that produces layered clusters. We applied MULIC to five PINs. Clusters correlate with known MIPS protein complexes. For example, a cluster of 79 proteins overlaps with a known complex of 88 proteins. Proteins in top cluster layers tend to be more representative of complexes than proteins in bottom layers. Lab work on finding unknown complexes or determining drug effects can be guided by top layer proteins.
