Parasites As Probes For Prehistoric Human Migrations? (Galley Proofs), Adauto Araújo, Karl J. Reinhard, Luiz F. Ferreira, Scott Lyell Gardner

School of Natural Resources: Faculty Publications

Host-specific parasites of humans are used to track ancient migrations. The archaeoparasitology of some intestinal parasites in the New World points to migration routes other than the Bering Land Bridge. Helminths have been found in mummies and coprolites in North and South America. Hookworms (Necator and Ancylostoma), whipworms (Trichuris trichiura) and other helminths require specific conditions for life-cycle completion. They could not survive in the cold climate of the northern region of the Americas. Therefore, humans would have lost some intestinal parasites while crossing Beringia. Evidence is provided here from published data of pre-Columbian sites for the peopling of the …

Antiretroviral Pre-Exposure Prophylaxis Prevents Vaginal Transmission Of Hiv-1 In Humanized Blt Mice, Paul W. Denton, Jacob D. Estes, Zhifeng Sun, Florence A. Othieno, Bangdong L. Wei, Anja K. Wege, Daniel A. Powell, Deborah A. Payne, Ashley T. Haase, J. Victor Garcia

Biology Faculty Publications

Background: Worldwide, vaginal transmission now accounts for more than half of newly acquired HIV-1 infections. Despite the urgency to develop and implement novel approaches capable of preventing HIV transmission, this process has been hindered by the lack of adequate small animal models for preclinical efficacy and safety testing. Given the importance of this route of transmission, we investigated the susceptibility of humanized mice to intravaginal HIV-1 infection.

Methods and Findings: We show that the female reproductive tract of humanized bone marrow–liver–thymus (BLT) mice is reconstituted with human CD4þ T and other relevant human cells, rendering these humanized mice …

Murky Wetlands Protection Following Rapanos V. United States,547u.S.715(2006), John S. Persell

Southern Illinois University Law Journal

The U.S. Supreme Court potentially dealt a severe blow to wetlands protection under the Clean Water Act with its 2006 plurality decision in Rapanos v. United States. As administered by the U.S. Army Corps of Engineers and the U.S. Environmental Protection Agency, the jurisdictional extent of the Clean Water Act's wetlands protection provisions is now less clear. Congress ambiguously described the reach of the Clean Water Act as extending to all "waters of the United States." Rather than deferring to the Army Corps' interpretation of that phrase, as is appropriate under the Chevron doctrine, the Rapanos plurality chose to overlook …

Novel Molecules For Intra-Oral Delivery Of Antimicrobials To Prevent And Treat Oral Infectious Diseases, Periathamby A. Raj, Latha Rajkumar, Andrew R. Dentino

School of Dentistry Faculty Research and Publications

New molecules were designed for efficient intra-oral delivery of antimicrobials to prevent and treat oral infection. The salivary statherin fragment, which has high affinity for the tooth enamel, was used as a carrier peptide. This was linked through the side chain of the N-terminal residue to the C-terminus of a defensin-like 12-residue peptide to generate two bifunctional hybrid molecules, one with an ester linkage and the other with an anhydride bond between the carrier and the antimicrobial components. They were examined for their affinity to a HAP (hydroxyapatite) surface. The extent of the antimicrobial release in human whole saliva was …

Expectation Modulates Human Brain Responses To Acute Cocaine: A Functional Magnetic Resonance Imaging Study, Peter Kufahl, Zhu Li, Robert C. Risinger, Charles Rainey, Linda B. Piacentine, Gaohong Wu, Alan S. Bloom, Zheng Yang, Shi-Jiang Li

College of Nursing Faculty Research and Publications

Background

Human expectation of psychoactive drugs significantly alters drug effects and behavioral responses. However, their neurophysiological mechanisms are not clear. This study investigates how cocaine expectation modulates human brain responses to acute cocaine administration.

Methods

Twenty-six right-handed non–treatment-seeking regular cocaine abusers participated in this study. Changes in blood oxygenation level-dependent (BOLD) signals were measured, and online behavioral ratings during cocaine expectation and acute cocaine administration were recorded.

Results

Distinct regional characteristics in BOLD responses to expected and unexpected cocaine infusions were observed in the medial orbitofrontal gyrus (Brodmann area [BA] 11), frontal pole (BA 10), and anterior cingulate gyrus regions. …

Preparation And Characterization Of Tapioca Starch–Poly(Lactic Acid) Nanocomposite Foams By Melt Intercalation Based On Clay Type, Siew-Yoong Lee, Han Chen, Milford Hanna

Department of Agricultural and Biological Systems Engineering: Dissertations, Theses, and Student Research

Abstract Tapioca starch (TS), poly(lactic acid) (PLA), and four different organoclays (Cloisite 10A, Cloisite 25A, Cloisite 93A and Cloisite 15A) were used to produce nanocomposite foams by melt-intercalation. Structural, thermal, physical and mechanical properties were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), differential scanning calorimetry (DSC), and an Instron universal testing machine, respectively. The first XRD peaks for all four nanocomposite foams, were observed to shift to lower angles, indicating that intercalation occurred. The extent of intercalation depended on the type of organoclay and was exhibited in the sequence of Cloisite 10A > 25A > 93A > 15A. Glass transition temperatures …

Assessment Of Paper Birch Trees Tapped For Sap Harvesting Near Fairbanks, Alaska, Lori Trummer, Tom Malone

Publications

With increased growth in the birch sap extraction industry, the need for assessments of tree health and sustainability of birch tapping practices also grows. Site visits and evaluation of tapping practices were conducted at two commercial harvest locations in the Fairbanks area, Eva Creek in Ester and Cache Creek near Murphy Dome in 2007. In this evaluation we report on walk through observations and a pilot dissection study of tapped trees at each location. Numerous improper tapping practices are reported as well as breach of the Alaska Birch Syrupmakers’ Association (ABSA) “Best Practices Guidelines for Tree Tapping”. There will be …

Dealing With The Malicious Insider, Andy Jones, Carl Colwill

Australian Information Security Management Conference

This paper looks at a number of issues relating to the malicious insider and the nature of motivation, loyalty and the type of attacks that occur. The paper also examines the changing environmental, social, cultural and business issues that have resulted in an increased exposure to the insider threat. The paper then discusses a range of measures that can be taken to reduce both the likelihood of an attack and the impact that such an attack may have. These measures should be driven by focused and effective risk management processes.

Monolayer-Protected Nanoparticle Film Assemblies As Platforms For Controlling Interfacial And Adsorption Properties In Protein Monolayer Electrochemistry, Andrew F. Loftus, Katelyn P. Reighard, Susanna A. Kapourales, Michael C. Leopold

Chemistry Faculty Publications

Assembled films of nonaqueous nanoparticles, known as monolayer-protected clusters (MPCs), are investigated as adsorption platforms in protein monolayer electrochemistry (PME), a strategy for studying the electron transfer (ET) of redox proteins. Modified electrodes featuring MPC films assembled with various linking methods, including both electrostatic and covalent mechanisms, are employed to immobilize cytochrome c (cyt c) for electrochemical analysis. The background signal (non-Faradaic current) of these systems is directly related to the structure and composition of the MPC films, including nanoparticle core size, protecting ligand properties, as well as the linking mechanism utilized during assembly. Dithiol-linked films of Au225(C6)75 are …

Using Regression Models To Analyze Randomized Trials: Asymptotically Valid Hypothesis Tests Despite Incorrectly Specified Models, Michael Rosenblum, Mark J. Van Der Laan

U.C. Berkeley Division of Biostatistics Working Paper Series

Regression models are often used to test for cause-effect relationships from data collected in randomized trials or experiments. This practice has deservedly come under heavy scrutiny, since commonly used models such as linear and logistic regression will often not capture the actual relationships between variables, and incorrectly specified models potentially lead to incorrect conclusions. In this paper, we focus on hypothesis test of whether the treatment given in a randomized trial has any effect on the mean of the primary outcome, within strata of baseline variables such as age, sex, and health status. Our primary concern is ensuring that such …
