The Impact Of Gut Passage By Binturongs (Arctictus Binturong) On Seed Germination, Christina P. Colon, Ahimsa Campos-Arceiz

Publications and Research

Binturongs (Arctictis binturong) are the largest of Asian civets and, due to their highly frugivorous diet, are expected to play an important role in seed dispersal processes. To study the effect of binturong gut passage on seed viability, we fed 10 captive binturongs with fruits of longan (Dimocarpus longan), papaya (Carica papaya) and chiku (Manilkara zapota), collected the seeds they defaecated, and planted these to determine seed germination rate and time. Of the defaecated seeds, 90.4% passed through binturong gut intact in under nine hours, and 99.4% passed in under 33 hours. Chiku seeds had the highest germination rate (35.7% …

Expansion Of Electronic Health Record-Based Screening, Prevention, And Management Of Diabetes In New York City, Jeanine Albu, Nancy Sohler, Brenda Matti-Orozco, Jordan Sill, Daniel Baxter, Gary Burke, Edwin Young

Publications and Research

To address the increasing burden of diabetes in New York City, we designed 2 electronic health records (EHRs)-facilitated diabetes management systems to be implemented in 6 primary care practices on the West Side of Manhattan, a standard system and an enhanced system. The standard system includes screening for diabetes. The enhanced system includes screening and ensures close patient follow-up; it applies principles of the chronic care model, including community–clinic linkages, to the management of patients newly diagnosed with diabetes and prediabetes through screening. We will stagger implementation of the enhanced system across the 6 clinics allowing comparison, through a quasi-experimental …

Nutrient Timing Revisited: Is There A Post-Exercise Anabolic Window?, Alan Albert Aragon, Brad Jon Schoenfeld

Publications and Research

Nutrient timing is a popular nutritional strategy that involves the consumption of combinations of nutrients--primarily protein and carbohydrate--in and around an exercise session. Some have claimed that this approach can produce dramatic improvements in body composition. It has even been postulated that the timing of nutritional consumption may be more important than the absolute daily intake of nutrients. The post-exercise period is widely considered the most critical part of nutrient timing. Theoretically, consuming the proper ratio of nutrients during this time not only initiates the rebuilding of damaged muscle tissue and restoration of energy reserves, but it does so in …

The Passiflora Tripartita (Banana Passion) Fruit: A Source Of Bioactive Flavonoid C-Glycosides Isolated By Hsccc And Characterized By Hplc–Dad–Esi/Ms/Ms, Mario J. Simirgiotis, Guillermo Schmeda-Hirschmann, Jorge Bórquez, Edward J. Kennelly

Publications and Research

The banana passion fruit (Passiflora tripartita Breiter, Passifloraceae) known as “tumbo” is very appreciated in tropical and subtropical countries of South America. Methanolic extracts from peel and the fruit juice of P. tripartita growing in Chile were analyzed for antioxidant capacity as well as for flavonoid and phenolic content. A chromatographic method was developed for the rapid identification of the main phenolics in the samples by HPLC-DAD and HPLC-MS. The fast fingerprint analysis allowed the detection of eighteen flavonoid C-glycosides and four flavonoid O-glycoside derivatives which were characterized by UV spectra and ESI-MS-MS analysis. Several of the C-glycosides detected are …

Sexual Orientation And Functional Pain In U.S. Young Adults: The Mediating Role Of Childhood Abuse, Andrea L. Roberts, Margaret Rosario, Heather L. Corliss, David Wypij, Jennifer R. Lightdale, S. Bryn Austin

Publications and Research

Objective: Pain without known pathology, termed ‘‘functional pain,’’ causes much school absenteeism, medication usage, and medical visits. Yet which adolescents are at risk is not well understood. Functional pain has been linked to childhood abuse, and sexual orientation minority youth (gay, lesbian, bisexual, ‘‘mostly heterosexual,’’ and heterosexual with same-sex sexual contact) are more likely to be victims of childhood abuse than heterosexuals, thus may be at greater risk of functional pain.

Methods: We examined sexual orientation differences in past-year prevalence of functional headache, pelvic, and abdominal pain and multiple sites of pain in 9,864 young adults (mean age = …

Allometric Scaling And Resource Limitations Model Of Tree Heights: Part 1. Model Optimization And Testing Over Continental Usa, Yuli Shi, Sungho Choi, Xiliang Ni, Sangram Ganguly, Gong Zhang, Hieu V. Duong, Michael A. Lefsky, Marc Simard, Sassan S. Saatchi, Shihyan Lee, Wenge Ni-Meister, Shilong Piao, Chunxiang Cao, Ramakrishna R. Nemani, Ranga B. Myneni

Publications and Research

A methodology to generate spatially continuous fields of tree heights with an optimized Allometric Scaling and Resource Limitations (ASRL) model is reported in this first of a multi-part series of articles. Model optimization is performed with the Geoscience Laser Altimeter System (GLAS) waveform data. This methodology is demonstrated by mapping tree heights over forested lands in the continental USA (CONUS) at 1 km spatial resolution. The study area is divided into 841 eco-climatic zones based on three forest types, annual total precipitation classes (30 mm intervals) and annual average temperature classes (2 °C intervals). Three model parameters (area of single …

Functional Neural Correlates Of Attentional Deficits In Amnestic Mild Cognitive Impairment, Nicholas T. Van Dam, Mary Sano, Effie M. Mitsis, Hillel T. Grossman, Xiaosi Gu, Yunsoo Park, Patrick R. Hof, Jin Fan

Publications and Research

Although amnestic mild cognitive impairment (aMCI; often considered a prodromal phase of Alzheimer’s disease, AD) is most recognized by its implications for decline in memory function, research suggests that deficits in attention are present early in aMCI and may be predictive of progression to AD. The present study used functional magnetic resonance imaging to examine differences in the brain during the attention network test between 8 individuals with aMCI and 8 neurologically healthy, demographically matched controls. While there were no significant behavioral differences between groups for the alerting and orienting functions, patients with aMCI showed more activity in neural regions …

Allometric Scaling And Resource Limitations Model Of Tree Heights: Part 2. Site Based Testing Of The Model, Sungho Choi, Xiliang Ni, Yuli Shi, Sangram Ganguly, Gong Zhang, Hieu V. Duong, Michael A. Lefsky, Marc Simard, Sassan S. Saatchi, Shihyan Lee, Wenge Ni-Meister, Shilong Piao, Chunxiang Cao, Ramakrishna R. Nemani, Ranga B. Myneni

Publications and Research

The ultimate goal of this multi-article series is to develop a methodology to generate continuous fields of tree height and biomass. The first paper demonstrated the need for Allometric Scaling and Resource Limitation (ASRL) model optimization and its ability to generate spatially continuous fields of tree heights over the continental USA at coarse (1 km) spatial resolution. The objective of this second paper is to provide an assessment of that approach at site scale, specifically at 12 FLUXNET sites where more accurate data are available. Estimates of tree heights from the Geoscience Laser Altimeter System (GLAS) waveform data are used …

The Prion Dilemma Confounding Science Educators, Igor V. Zaitsev, Ling Chen, Susie Boydston-White, Manita Pavel, Svetlana N. Shugaeva, Alla G. Petrova, Oksana V. Williams

Publications and Research

In this paper, the issue of the prion hypothesis, a simmering controversy within the scientific community, is addressed. We inquire into the appropriateness of the use of certain augmentations and rhetoric approaches used during scientific debates, as well as the aptness of unequivocal statements in textbooks that indicate “abnormal prions” as a primary cause of Transmissible Spongiform Encephalopathies.

Tolerance Of Roadside And Old Field Populations Of Common Teasel (Dipsacus Fullonum Subsp. Sylvestris) To Salt And Low Osmotic Potentials During Germination, Laura L. Beaton, Susan A. Dudley

Publications and Research

Maternal families from roadside populations of Dipsacus fullonum subsp. sylvestris displayed greater tolerance of both high salinity and drought during germination than families from old field populations. However, the tolerances were not correlated, indicating that they are separate traits.

Changes In Natural Killer Cell Activation And Function During Primary Hiv-1 Infection, Vivek Naranbhai, Marcus Altfeld, Salim S. Abdool Karim, Thumbi Ndung’U, Quarraisha Abdool Karim, William H. Carr

Publications and Research

Background: Recent reports suggest that Natural Killer (NK) cells may modulate pathogenesis of primary HIV-1 infection. However, HIV dysregulates NK-cell responses. We dissected this bi-directional relationship to understand how HIV impacts NK-cell responses during primary HIV-1 infection.

Methodology/Principal Findings: Paired samples from 41 high-risk, initially HIV-uninfected CAPRISA004 participants were analysed prior to HIV acquisition, and during viraemic primary HIV-1 infection. At the time of sampling post-infection five women were seronegative, 11 women were serodiscordant, and 25 women were seropositive by HIV-1 rapid immunoassay. Flow cytometry was used to measure NK and T-cell activation, NK-cell receptor expression, cytotoxic and cytokine-secretory functions, …

From Toxic Tours To Growing The Grassroots: Tensions In Critical Pedagogy And Community Development, Celina Su, Isabelle Jagninski

Publications and Research

Structural inequalities in American public education are inextricably tied to deep-seated patterns of racial and economic segregation. Children in poor neighborhoods are less likely to have the household resources, neighborhood institutions, or school amenities necessary for a good, challenging education. In response, a growing number of organizations have launched initiatives to simultaneously revitalize neighborhoods and improve public education, emphasizing youth participation as an essential component in their efforts. We draw upon ethnographic data from two such organizations to examine their practice of place-based critical pedagogy in community development. We focus on how they engage marginalized, “hard-to-reach” youth via (1) experiential …

Generalized Least-Squares Regressions I: Efficient Derivations, Nataniel Greene

Publications and Research

Ordinary least-squares regression suffers from a fundamental lack of symmetry: the regression line of y given x and the regression line of x given y are not inverses of each other. Alternative symmetric regression methods have been developed to address this concern, notably: orthogonal regression and geometric mean regression. This paper presents in detail a variety of least squares regression methods which may not have been known or fully explicated. The derivation of each method is made efficient through the use of Ehrenberg's formula for the ordinary least-squares error and through the extraction of a weight function g(b) which characterizes …

The Student As Subaltern: Reconsidering The Role Of Student Life Material Collections At North American Universities, Jessica L. Wagner

Publications and Research

This article argues for college and university archivists to undertake advocacy and activism to better document student life. It discusses key shifts in archival and historical theory that supported an interest in collecting from a wide variety of people rather than just elites. Next, it describes recent archival scholarship on student life materials and considers the extent to which college and university archives are actively documenting the student experience via the collection of these materials. Analysis of the results of a survey of college and university archivists about the nature of these collections sheds further light on prevailing opinions of …

Teaching And Pedagogy In Africana Studies: Implications Of An African Worldview, Karanja Keita Carroll

Publications and Research

The African worldview has informed much of the African centered scholarship produced within contemporary Africana/Black Studies. In doing so, the African worldview has functioned as the methodological foundation for the production, interpretation and dissemination of knowledge related to people of African ancestry. Africana Studies instructors and professors can also utilize the philosophical assumptions that inform the African worldview to create and recreate dynamic, culturally centered teaching practices. Given the central role of teaching at the undergraduate level within the discipline of Africana Studies it is crucial that instructors and professors concentrate on the development of discipline-specific pedagogical practices. This essay …
