Transport Of Galectin-3 Between The Nucleus And Cytoplasm. I. Conditions And Signals For Nuclear Import, Peter J. Davidson, Su Yin Li, Andrew G. Lohse, Rianna Vandergaast

University Faculty Publications and Creative Works

Galectin-3, a factor involved in the splicing of pre-mRNA, shuttles between the nucleus and the cytoplasm. We have engineered a vector that expresses the fusion protein containing the following: (a) green fluorescent protein as a reporter of localization, (b) bacterial maltose-binding protein to increase the size of the reporter polypeptide, and (c) galectin-3, whose sequence we wished to dissect in search of amino acid residues vital for nuclear localization. In mouse 3T3 fibroblasts transfected with this expression construct, the full-length galectin-3 (residues 1-263) fusion protein was localized predominantly in the nucleus. Mutants of this construct, containing truncations of the galectin-3 …

An In-Depth Investigation Of The Divine Ratio, Birch Fett

The Mathematics Enthusiast

The interesting thing about mathematical concepts is that we can trace their development or discoveries throughout history. Most cultures of the ancient world had some form of mathematics, and these basic skills developed into what we now call modern mathematics. The divine ratio is similar in that it was used in many different sections of history. The divine ratio, sometimes called the golden ratio or golden section, has been found in very diverse areas. The mathematical concepts of the golden ration have been found throughout nature, in architecture, music as well as in art. Phi is an astonishing number because …

Frames Of Reference And Achievement In Elementary Arithmetic, Eddie M. Gray, Demetra Pitta-Pantazi

The Mathematics Enthusiast

This paper considers the relationship between 8-11 years old students’ numerical achievement and a possible disposition towards the construction of particular frames of reference. The paper uses the characteristics of a variety of kinds of images to focus upon frames of reference and explores a possible relationship between children’s verbal descriptions of concrete and abstract nouns and the different ways they respond to aspects of elementary arithmetic. It seeks to establish whether or not children towards the extremes of arithmetical achievement (low and high achievement) have a disposition towards different kinds of frames of reference. The analysis suggests that at …

Negative Effect Of Zebra Mussels On Foraging And Habitat Use By Lake Sturgeon (Acipenser Fulvescens), D. J. Mccabe, Mark Beekey, A. Mazloff, I. E. Marsden

Biology Faculty Publications

1. Lake sturgeon (Acipenser fulvescens) are threatened or endangered throughout much of their range. Juvenile sturgeon utilize sandy and silty habitats extensively during their growth. Invasive zebra mussels change the nature of sandy and silty habitats because they settle on and coat the habitat with the shells of living and dead individuals. The potential impacts of this increased habitat complexity on lake sturgeon is unknown. 2. Juvenile lake sturgeon habitat choice was assessed in laboratory experiments, and zebra mussel impact on the foraging success of juvenile lake sturgeon on three different prey species was measured. 3. Sturgeon foraging on chironomids …

No Direction Home: Will The Law Keep Pace With Human Tracking Technology To Protect Individual Privacy And Stop Geoslavery, William A. Herbert

Publications and Research

Increasingly, public and private employers are utilizing human tracking devices to monitor employee movement and conduct. Due to the propensity of American labor law to give greater weight toemployer property interests over most employee privacy expectations, there are currently few limitations on the use of human tracking in employment. The scope and nature of current legal principles regarding individual privacy are not sufficient to respond to the rapid development and use of human tracking technology. The academic use of the phrase “geoslavery” to describe the abusive use of such technology underscores its power. This article examines the use of such …

Perceptions Of Corporate Social Responsibility: An Empirical Study In Singapore; Strategic Management Policy, Gilbert Yip Wei Tan, Rajah Vellan Komaran

Research Collection Lee Kong Chian School Of Business

In Singapore, there is no doubt that there have been efforts by various local and foreign corporations to incorporate some CSR principles in their operations. Indeed, there was a national initiative modeled after the tripartite approach to industrial relations where national economic and industrial issues are collectively resolved by the government, employers and employees. Against the backdrop of this national initiative and the effort by some corporations to incorporate CSR principles, not much is really known about the state of affairs in Singapore.

Mechanical Properties Of Skin Wounds After Atropa Belladonna Application In Rats, T Toporcer, T Grendel, B Vidinský, P Gál, J Sabo, R Hudák

Journal of Metals, Materials and Minerals

Atropa belladonna is a topical agent used in the treatment of skin wounds in Slovak folk medicine. The aim of this study was to asses the effect of A. belladonna extract on wound tensile strength in Sprague-Dawley rats. Twenty four rats were randomly divided into 3 groups of 8 animals. Two symmetrical skin incisions were performed on the back of each animal and immediately sutured. In the 1st group A. belladonna extract was not applied and the group served as a control. The animals in the 2nd group were treated by daily application of A. Belladonna extract during the first …

He concludes with three recommendations for diversifying the local economy: establishing a base (export-oriented) industry in agriculture, …

Transcriptional Regulation Of The Borrelia Burgdorferi Antigenically Variable Vlse Surface Protein, Tomasz Bykowski, Kelly Babb, Kate Von Lackum, Sean P Riley, Steven J Norris, Brian Stevenson

Faculty, Staff and Student Publications

The Lyme disease agent Borrelia burgdorferi can persistently infect humans and other animals despite host active immune responses. This is facilitated, in part, by the vls locus, a complex system consisting of the vlsE expression site and an adjacent set of 11 to 15 silent vls cassettes. Segments of nonexpressed cassettes recombine with the vlsE region during infection of mammalian hosts, resulting in combinatorial antigenic variation of the VlsE outer surface protein. We now demonstrate that synthesis of VlsE is regulated during the natural mammal-tick infectious cycle, being activated in mammals but repressed during tick colonization. Examination of cultured B. …

Corporate Social Responsibility, Akbar Abdul Ali

Business Review

This paper addresses fundamental questions of corporate governance that, why corporations need to accept responsibility for the social problems that plague our nation? Discussion of corporate actions (i.e., mass layoffs, high CEO payoffs, discrimination in the work force) and how they are ultimately responsible for many of our social disorder (i.e., crime, suicide, alcoholism, domestic violence etc.). Article examines the corporate ethics and international business and how corporate law inhibits corporate social responsibility. I also discuss the philanthropic role of corporations to examine different perceptions of corporate ethics and its social responsibility which is generally lacking in Pakistan.

Language And The Structuring Of The Intellect: Towards The Realization Of The Total Man, D.U. Opata

Business Review

The critical definition of the concept, “the total man”, is encumbered by lot of difficulties – epistemic and pragmatic. First, a man qua man because he is a total entity, a complete homo sapein. However, the phrase “the total man” is used here in a stipulative sense to distinguish the liberally educated person from the pure specialist. Second, even in this contextual sense, the concept of the liberal-minded person is still a problematic. Is liberal-mindedness predicated on a person’s breadth of knowledge, even if in the process the person becomes the proverbial “rolling stone that gathers no mass”? Or is …

The Influence Of Children On Family Purchase Decisions: A Phenomenological Approach, Usman Majeed, Nadia S. Banoori

Business Review

This study was conducted to understand the influence of school-going children between seven to ten years of age on family’s buying decision-making in the area of North Nazimabad. A sample of three children was chosen to be interviewed and were asked a number of questions related to their influence on purchase. Later, their parents were interviewed to counter-check their perceptions about their children’s influence. The results showed that children did exert some influence on decisions, especially in cases where the product was for their own use. Another result was that the level of understanding of the children was high enough …

Sexually Dimorphic Developmental Patterns Of Chemosensory Behaviors In African Elephants (Loxodonta Africana), Dhaval Kartik Vyas

College of Graduate Studies: Theses & Dissertations

Like many polygynous mammals, African elephants exhibit social dimorphism in which females reside in matriarchal groups while males often travel alone or in bachelor groups. Males search for receptive mates who may advertise their condition through chemical and other signals. The difference in adult lifestyles suggests that the developmental pattern of communication for the two sexes should diverge when the social environment and reproductive opportunities of males and females begin to differ. In this study, I examined the differences between the sexes and across four age classes (calves, juveniles, subadults and adults) in the performance of chemosensory behaviors. African elephants …

Crossing The Chasm: The Xid Technologies Story, Arcot Desai Narasimhalu, Roberto Mariani

Research Collection School Of Computing and Information Systems

XID Technologies is a face processing start up company built initially around a disruptive face recognition technology. The technology innovation came from Kent Ridge Digital Labs, a publicly funded software research laboratory in Singapore. Face recognition is the least intrusive and harmless among the various biometric solutions available in the market. The basic approach to human face recognition is to identify a robust feature set that was unique enough to differentiate amongst the many millions of human faces that the system was required to verify. The technology innovation used by XID framed the problem differently and thereby overcame the challenges …

'A Hundred Flowers Bloom': The Re-Emergence Of The Chinese Press In Post-Suharto Indonesia, Chang Yau Hoon

Research Collection School of Social Sciences

During the whole 32 years of Suharto’s regime (1966–98), Chinese publications and the use of Chinese language in public were officially banned in Indonesia. As a result, printed matter in Chinese characters that entered Indonesia was classified as ‘prohibited imports’ (Heryanto 1999: 327). This prohibition came to an end after the fall of Suharto, as part of the process of democratization and Reformasi. The post-Suharto era of Reformasi is thus celebrated for the dramatic revival of the freedom of the press and media in Indonesia and many previously banned as well as new publications have emerged since Suharto’s fall. The …

An Operational Model For Mobile Sensor Cloud Management, Indrajeet Kalyankar

Electrical & Computer Engineering Theses & Dissertations

Mobile sensors provide a safe, cost effective method for gathering information in hazardous environments. When the hazardous environment is either unexplored, such as the surface of Mars, or unanticipated, such as the result of chemical contamination, it is desirable for a system to gather information with a minimal amount of outside control (localization, decision control, etc.) and prepositioned sensors. If one takes a look at the number of the sensors deployed on a scale, at the lower end is the sole, multipurpose sensor unit. The upper end deals with hordes of inexpensive, expendable sensors. In the middle, a cluster of …

Defensin Transcript Distribution In Tissues And Life Stages Of The Ixodid Ticks Amblyomma Americanum And Ixodes Scapularis, Stephanie M. Todd

Biological Sciences Theses & Dissertations

A number of bacterial, viral, and protozoan diseases are transmitted to humans via arthropods. Arthropods possess an innate immune system to destroy invading microorganisms. However, arthropods unable to rid their systems of pathogens function as disease vectors. The American dog tick, Dermacentor variabilis, destroys invading Borrelia burgdorferi spirochetes, preventing transmission. In contrast, the black-legged tick, Ixodes scapularis, which is unable to destroy acquired B. burgdorferi, successfully vectors the pathogen. The Lone Star tick, Amblyomma americanum, vectors a similar pathogen called Borrelia lonestari. The distribution of defensin, an antimicrobial peptide of the innate immune system, was examined in A. americanum and/. …

Chemical Evidence For Dietary Toxin Sequestration In The Asian Snake Rhabdophis Tigrinus, Deborah A. Hutchinson

Biological Sciences Theses & Dissertations

Rhabdophis tigrinus (Colubridae: Natricinae) is an oviparous, bufophagous (toad-eating) snake from eastern Asia that possesses defensive integumentary glands on the neck known as nuchal glands. These glands are used in antipredator displays and typically contain bufadienolide toxins. Whereas toads are known to synthesize bufadienolide steroids from cholesterol precursors, we found that chemically undefended R. tigrinus must sequester bufadienolides from ingested toads in order to exhibit these compounds in their nuchal glands. Chemically defended females are capable of provisioning their embryos with these toxins so their unfed hatchlings possess defensive bufadienolides prior to consuming toads themselves. All of the hatchling R. …

Learning As A Nonlinear Line Of Attraction For Pattern Association, Classification And Recognition, Ming-Jung Seow

Electrical & Computer Engineering Theses & Dissertations

Development of a mathematical model for learning a nonlinear line of attraction is presented in this dissertation, in contrast to the conventional recurrent neural network model in which the memory is stored in an attractive fixed point at discrete location in state space. A nonlinear line of attraction is the encapsulation of attractive fixed points scattered in state space as an attractive nonlinear line, describing patterns with similar characteristics as a family of patterns.

It is usually of prime imperative to guarantee the convergence of the dynamics of the recurrent network for associative learning and recall. We propose to alter …

Extracellular Superoxide Dismutase Protects Cardiomyocytes During Hyperoxia, Mervat Elsayed Ali

Theses and Dissertations in Biomedical Sciences

Reactive oxygen species are implicated in tissue damage in many cardiovascular diseases. The current study was designed to test the hypothesis that exposure to high inspired oxygen concentrations (100%) damages cardiac mitochondria and that a biogenic response is needed for cell survival. The study was done in mice with a transgene (TG) for extracellular superoxide dismutase (EC-SOD) or with the EC-SOD gene knockout (KO). Adult EC-SOD mice and their wild type littermates and EC-SOD KO mice and their wild type littermates were exposed to 100% oxygen for 6 hours and for 72 hours, and the hearts were subsequently removed under …

Cellular Mechanism Of Arglabin-Dimethylaminohydrochloride Cytotoxicity, Xiaofei Qin

Theses and Dissertations in Biomedical Sciences

Cancer is the second leading killer in the United States. Anticancer drug development is always based on the understanding of molecular and cellular mechanisms of carcinogenesis, as well as comprehensive knowledge of potential anticancer drugs. Arglabin-dimethylaminohydrochloride (arglabin-DMA) represents one of the new classes of anti-cancer agents that have shown promise in suppressing the growth of various tumor cells. However, the cellular mechanism of arglabin-DMA cytotoxic effects on tumor cells is still unclear. The current study was to determine the farnesyltransferase (FTase) inhibitory activity of arglabin-DMA and to investigate the effects of arglabin-DMA on three proteins: Ras, Rho and cyclin kinase …

Equality And The Dialectic Between Identity And Difference, Michel Rosenfeld

Articles

Modern equality as derived from the Enlightenment has always had problems with difference. Whereas feudalism set inequality as the baseline, modern society sets equality as the baseline, but allows for unequal treatment based on differences. Thus, differences among the sexes have been invoked to treat women as inferiors and racial differences to deprive racial minorities of equal treatment. Liberalism has countered these moves by promoting a conception of equality as identity according to which race or gender-based differences are irrelevant for purposes of political participation or employment. More recent claims for equality based on identity politics which callfor a type …

International Volunteerism In The United States, 2005, Benjamin Lough

Center for Social Development Research

This working paper uses 2005 CPS data to describe the frequency of international volunteerism in the United States by select demographic characteristics and length of service abroad. Nearly one million individuals reported volunteering internationally at least once in 2005. Young or middle-aged college graduates with higher-incomes, employed full-time, and married without dependent children were the most frequent candidates for service abroad. The majority of volunteers spent two weeks or less overseas, and volunteered with a faith-based organization either domestically or internationally. Limitations in the data help identify areas needing further research.
