Genomics-Assisted Characterization Of A Breeding Collection Of Apios Americana, An Edible Tuberous Legume, Vikas Belamkar, Andrew Farmer, Nathan T. Weeks, Scott R. Kalberer, William J. Blackmon, Steven B. Cannon
Department of Agronomy and Horticulture: Faculty Publications
For species with potential as new crops, rapid improvement may be facilitated by new genomic methods. Apios (Apios americana Medik.), once a staple food source of Native American Indians, produces protein-rich tubers, tolerates a wide range of soils, and symbiotically fixes nitrogen. We report the first high-quality de novo transcriptome assembly, an expression atlas, and a set of 58,154 SNP and 39,609 gene expression markers (GEMs) for characterization of a breeding collection. Both SNPs and GEMs identify six genotypic clusters in the collection. Transcripts mapped to the Phaseolus vulgaris genome–another phaseoloid legume with the same chromosome number–provide provisional genetic …
Effects Of Parasitism And Mite Control Methods On European Starling Development, Aderinsola Oluwasikemi Odetunde
Effects Of Parasitism And Mite Control Methods On European Starling Development, Aderinsola Oluwasikemi Odetunde
Theses and Dissertations
Certain developmental stressors can lead to developmental trade-offs in young organisms. Hematophagous ectoparasites are a common stressor experienced by European starlings, and we wished to explore what aspects of an ectoparasite infestation drove trade-offs. The first part of this study was to test the hypothesis that blood loss was the sole mediator of trade-offs due to hematophagous ectoparasite infestation. We used nestlings that were exposed to mites in the nests, nestlings in mite-reduced nests experiencing supplementary blood loss, and nestlings in mite reduced nests with no supplementary blood loss. We also used a new heat treatment to reduce mites in …
A World Wide Web Of Unwanted Children: The Practice, The Problem, And The Solution To Private Re-Homing, S. Megan Testerman
A World Wide Web Of Unwanted Children: The Practice, The Problem, And The Solution To Private Re-Homing, S. Megan Testerman
Florida Law Review
A deplorable practice has emerged in the world of adoption. Adoptive families are now using the Internet to give their unwanted adopted children over to complete strangers, some of whom are traffickers, pedophiles, child pornographers, or worse. This practice is known as private rehoming. Through the use of online message boards and a simple notarized power of attorney document, adoptive parents are circumventing the adoption system—including its home study and background check requirements for prospective parents—and placing children in great danger. Because only a handful of states have enacted legislation directly targeting private re-homing and because no such legislation exists …

NYMC Faculty Publications
Background Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specific mortality for 249 causes in 195 countries and territories from 1980 to 2015. These results informed an in-depth investigation of observed and expected mortality patterns based on sociodemographic measures. Methods We estimated all-cause mortality by age, sex, geography, and year using an improved analytical approach originally developed for GBD 2013 and GBD 2010. Improvements included refinements to the estimation of child …

NYMC Faculty Publications
Background Non-fatal outcomes of disease and injury increasingly detract from the ability of the world's population to live in full health, a trend largely attributable to an epidemiological transition in many countries from causes affecting children, to non-communicable diseases (NCDs) more common in adults. For the Global Burden of Diseases, Injuries, and Risk Factors Study 2015 (GBD 2015), we estimated the incidence, prevalence, and years lived with disability for diseases and injuries at the global, regional, and national scale over the period of 1990 to 2015. Methods We estimated incidence and prevalence by age, sex, cause, year, and geography with …

Peninsula Medical School
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context. METHODS: We used the comparative risk assessment framework developed for previous iterations of the Global Burden of Disease Study to estimate attributable deaths, disability-adjusted life-years (DALYs), and trends in exposure by age group, sex, year, and geography for 79 behavioural, environmental and occupational, and metabolic risks or …

Assessing Feasibility And Readiness To Address Obesity Through Policy In American Indian Reservations, Valarie Blue Bird Jernigan, Gail Boe, Carolyn Noonan, Leslie Carroll, Dedra Buchwald
Assessing Feasibility And Readiness To Address Obesity Through Policy In American Indian Reservations, Valarie Blue Bird Jernigan, Gail Boe, Carolyn Noonan, Leslie Carroll, Dedra Buchwald
Journal of Health Disparities Research and Practice
The Institute of Medicine and Centers for Disease Control and Prevention (CDC) have identified policy and environmental strategies as critical to the prevention and control of obesity. However such strategies are rare in American Indian communities despite significant obesity-related disparities. Tribal policymaking processes differ by tribal nation and are often poorly understood by researchers and public health practitioners, hindering the dissemination, implementation, and successful scale-up of evidence-base obesity strategies in tribal communities. To address these gaps in knowledge we surveyed 138 diverse stakeholders in two American Indian reservations to assess the feasibility of and readiness to implement CDC-recommended obesity policy …

Healthcare Providers’ Perceptions Of Socioeconomically Disadvantaged Patients With Chronic Pain: A Qualitative Investigation, Nicole A. Hollingshead, Marianne S. Matthias, Matthew Bair, Adam T. Hirsh
Journal of Health Disparities Research and Practice
Socioeconomically disadvantaged individuals are at-risk for chronic pain and disparate care. In this qualitative study, we explored providers’ experiences with socioeconomically disadvantaged patients, with a particular focus on providers’: (1) perceptions of socioeconomically disadvantaged patients’ barriers to pain care, (2) attitudes towards this patient population, and (3) chronic pain decisions for these patients. Individual interviews were conducted with twenty-four healthcare providers. Providers discussed several patient-level access barriers, such as not having health insurance, financial constraints, and scheduling difficulties. Providers believed socioeconomically disadvantaged patients were at-risk to misuse prescription opioids and were less comfortable prescribing opioids to these patients. This investigation …

Family Based Treatment For Adults With Anorexia Nervosa Using Insights From Neurobiology, The Center For Balanced Living
Learning Showcase 2016: A Celebration of Discovery, Transformation and Success
Anorexia Nervosa (AN) is a biologically-based brain disorder, which has the highest death rate of all mental illnesses. No effective treatments exist for adults with severe and enduring AN (5-7+ years). Brain imaging studies at University of California San Diego on AN temperament, cognition and eating show common traits related to neural function. The temperaments are characterized by increased trait anxiety and state anxiety related to food and eating, high incidence of co-morbid anxiety disorders, high punishment sensitivity and low reward reactivity, elevated intolerance of uncertainty and exaggerated harm avoidance (HA). HA is a multifaceted temperament trait that contains elements …

A Novel Genetic Variant In Long Non-Coding Rna Gene Nexn-As1 Is Associated With Risk Of Lung Cancer, Hua Yuan, Hongliang Liu, Zhensheng Liu, Kouros Owzar
A Novel Genetic Variant In Long Non-Coding Rna Gene Nexn-As1 Is Associated With Risk Of Lung Cancer, Hua Yuan, Hongliang Liu, Zhensheng Liu, Kouros Owzar
Dartmouth Scholarship
Lung cancer etiology is multifactorial, and growing evidence has indicated that long non-coding RNAs (lncRNAs) are important players in lung carcinogenesis. We performed a large-scale meta-analysis of690,564 SNPs in 15,531 autosomal lncRNAs by using datasets from six previously published genome-wideassociation studies (GWASs) from the Transdisciplinary Research in Cancer of the Lung (TRICL) consortiumin populations of European ancestry. Previously unreported significant SNPs (P value < 1 × 10−7) were further validated in two additional independent lung cancer GWAS datasets from Harvard University anddeCODE. In the final meta-analysis of all eight GWAS datasets with 17,153 cases and 239,337 controls, a novel risk SNP rs114020893 in the lncRNA NEXN-AS1 region at 1p31.1 remained statistically significant(odds ratio = 1.17; 95% confidence interval = 1.11–1.24; P = 8.31 × 10−9). In further in silico analysis,rs114020893 was predicted to change the secondary structure of the lncRNA. Our finding indicates that SNP rs114020893 of NEXN-AS1 at 1p31.1 may contribute to lung cancer susceptibility.
Packaging Film Impact On Food Organoleptic Properties: An Experimental Study, Stefano Tamarindo, Carine Pastore
Packaging Film Impact On Food Organoleptic Properties: An Experimental Study, Stefano Tamarindo, Carine Pastore
Journal of Applied Packaging Research
Most packaged food products deteriorate in quality due to mass transfer phenomena such as moisture absorption, oxygen invasion, flavor loss, undesirable odor absorption and packaging material migration. An approach to increase the shelf life of the packaged food, while exploiting the advantages of flexible packaging, is to use flexible multi-layer polyethylene (PE)-based films including a barrier layer. This paper reviews different oxygen barrier layers used in Doy Pack flexible pouches for fruit puree and presents the impact of storage conditions on the organoleptic properties. In this study, the performances of five types of PE film pouched filled with fruit puree …

Flexible Packaging For High Pressure Treatments: Delamination Onset And Design Criteria Of Multilayer Structures, Giuseppe Mensitieri, Massimiliano Fraldi
Journal of Applied Packaging Research
Multi-layer flexible polymeric films employed for high pressure treatments of food packaging for pasteurization and sterilization frequently display delamination phenomena. This problem limits packaging reliability used for this treatment technology. This contribution is aimed at understanding the delamination phenomena of packaging structures under high pressures. Development of interlaminar stress fields, which promote localized delamination events, is here addressed by considering the case of mechanical failure of bi-layer structures. Analytical models and Finite Element based numerical simulations are exploited to this purpose. The theoretical and numerical results, that highlight the crucial role played by the mismatch of Young moduli and Poisson …
The Intersection Of American Indians/Alaskan Natives And The Child Welfare System: A Review Of The Literature, Rebecca J. Luth
The Intersection Of American Indians/Alaskan Natives And The Child Welfare System: A Review Of The Literature, Rebecca J. Luth
McNair Scholars Research Journal
American Indians/Alaskan Natives (AI/AN) have historically been forcefully integrated into the child welfare system. Their relationship began before a formal child welfare system was established in the United States and continues to the present. It is critical to examine AI/AN history and the child welfare system in the United States to fully understand their difficult and often damaging interactions. This paper will review the literature on this topic in an effort to highlight the intersectionality of AI/ AN children and families, and the policies and practices of the American child welfare system.

Faculty Publications – Biological Sciences
Nuptial gifts produced by males and transferred to females during copulation are common in insects. Yet, their precise composition and subsequent physiological effects on the female recipient remain unresolved. Male decorated crickets Gryllodes sigillatus transfer a spermatophore to the female during copulation that is composed of an edible gift, the spermatophylax, and the ampulla that contains the ejaculate. After transfer of the spermatophore, the female detaches the spermatophylax and starts to eat it while sperm from the ampulla are evacuated into the female reproductive tract. When the female has finished consuming the spermatophylax, she detaches the ampulla and terminates sperm …
