The Effects Of The Covid-19 Pandemic On Postgraduate Endodontic Programs In The United States, Bianca Aboubakare, James Chen, Johnah C. Galicia

Orthodontics and Endodontics Theses

In December 2019, the coronavirus disease 2019 (COVID-19) was first identified as an acute infectious disease in Wuhan, China and subsequently led to an ongoing pandemic. At the onset of the pandemic, dental professionals were understood to face the greatest exposure risk to SARS-Cov-2 due to aerosolization of fluids from the oral cavity and respiratory airways . As a result, dental professionals, including academic institutions and their students and residents halted much of their operations to minimize exposure risks and potentially slow the spread of infection to peers and patients alike. Currently, there is little in the literature that describes …

T-Lymphocyte Tyrosine Hydroxylase Regulates T H 17 T-Lymphocytes During Repeated Social Defeat Stress, Safwan K. Elkhatib, Cassandra M. Moshfegh, Gabrielle F. Watson, Adam J. Case

Journal Articles: Cellular & Integrative Physiology

Posttraumatic stress disorder (PTSD) is a debilitating psychiatric disorder which results in deleterious changes to psychological and physical health. Patients with PTSD are especially susceptible to life-threatening co-morbid inflammation-driven pathologies, such as autoimmunity, while also demonstrating increased T-helper 17 (TH17) lymphocyte-driven inflammation. While the exact mechanism of this increased inflammation is unknown, overactivity of the sympathetic nervous system is a hallmark of PTSD. Neurotransmitters of the sympathetic nervous system (i.e., catecholamines) can alter T-lymphocyte function, which we have previously demonstrated to be partially mitochondrial redox-mediated. Furthermore, we have previously elucidated that T-lymphocytes generate their own catecholamines, and strong …

Excluded From Our City: Clement Of Alexandria And The Porous Frontier Of Early Christian Identity, Jordan C. Goneau-Goncalves

Theology Graduate Theses

In the Paedagogus, the second volume of his three major works, Clement of Alexandria develops a “Christian” ethic and sense of identity, which is dependent on one’s “habits, deeds, and passions.”1 The work itself is directed toward “you who are children” and is intended to instruct Christians in matters of character and behavior.2 Though he is preoccupied with attempting to educate—rather, allowing his understanding of Christ to educate—Christians in regard to appropriate behaviors and values, thereby defining and maintaining a unique sense of Christian identity in late second century Alexandria, he is also at home in a …

The Disconnect Between Knowledge And Perceptions: A Study Of Fishermen’S Local Ecological Knowledge And Their Perception Of The State Of Fisheries And How These Are Managed In The Dominican Republic, Elizabeth Layli Mclean, Graham E. Forrester, Carlos G. Garcia-Quijano

Natural Resources Science Faculty Publications

Understanding what fishers know about the ecology of the fish they catch, and how they perceive the state and management of their fisheries can guide efforts towards more sustainable fishing practices. We tested relationships between fishers’ local ecological knowledge (LEK) and their perceptions of their fisheries and of marine protected areas in the Dominican Republic. A qualitative-quantitative methodological sequence using data from interviews with 152 multi-species fishers revealed variable, but generally high levels of LEK, particularly of habitat use and predator–prey interactions. The majority reported negative perceptions of the state of their fishery and were aware of local management actions. …

Online Sale Of Small Turtles Circumvents Public Health Regulations In The United States, Lauren E. Montague, Juliana M. Macrotrigiano, Niamh E. Keane, Hannah E. Marquardt, Jennifer A. Sevin, Nancy E. Karraker

Natural Resources Science Faculty Publications

In the United States (U.S.), pet turtles have been associated with outbreaks of salmonellosis, a serious and sometimes-fatal intestinal illness caused by Salmonella bacteria, with nearly 300,000 people being infected in some years. Children are particularly susceptible because of their propensity to put items, including small turtles, in their mouths. In 1975, a U.S. federal regulation prohibited the sale of turtles <4 inches (101.6 mm) in size, except for the purposes of export, scientific, or educational purposes. This regulation was established to reduce the incidence of salmonellosis, particularly in small children. Previous research has not evaluated the availability of turtles <4 inches in size on websites selling wildlife. We monitored 16 websites in 2021 and quantified listings of small turtles. We determined whether information on Salmonella, the 1975 federal regulation, or related state regulations were provided on the websites and determined legality of sales of small turtles by state regulations. We found that all 16 websites openly advertised and sold turtles <4 inches in size, but only half of these websites provided information about Salmonella and/or …

Conceptual And Methodological Advances In Habitat-Selection Modeling: Guidelines For Ecology And Evolution, Joseph M. Northrup, Eric Vander Wal, Maegwin Bonar, John Fieberg, Michel P. Laforge, Martin Leclerc, Christina M. Prokopenko, Brian Gerber

Natural Resources Science Faculty Publications

Habitat selection is a fundamental animal behavior that shapes a wide range of ecological processes, including animal movement, nutrient transfer, trophic dynamics and population distribution. Although habitat selection has been a focus of ecological studies for decades, technological, conceptual and methodological advances over the last 20 yr have led to a surge in studies addressing this process. Despite the substantial literature focused on quantifying the habitat-selection patterns of animals, there is a marked lack of guidance on best analytical practices. The conceptual foundations of the most commonly applied modeling frameworks can be confusing even to those well versed in their …

Forest Degradation Drives Widespread Avian Habitat And Population Declines, Matthew G. Betts, Zhiqiang Yang, Adam S. Hadley, Adam C. Smith, Josée S. Rousseau, Joseph M. Northrup, Joseph J. Nocera, Noel Gorelick, Brian Gerber

Natural Resources Science Faculty Publications

In many regions of the world, forest management has reduced old forest and simplified forest structure and composition. We hypothesized that such forest degradation has resulted in long-term habitat loss for forest-associated bird species of eastern Canada (130,017 km2) which, in turn, has caused bird-population declines. Despite little change in overall forest cover, we found substantial reductions in old forest as a result of frequent clear-cutting and a broad-scale transformation to intensified forestry. Back-cast species distribution models revealed that breeding habitat loss occurred for 66% of the 54 most common species from 1985 to 2020 and was strongly …

How Is H. Pylori Implicated In The Etiology Of Cancer?, Chaya S. Lowy Jan 2022

How Is H. Pylori Implicated In The Etiology Of Cancer?, Chaya S. Lowy

The Science Journal of the Lander College of Arts and Sciences

Gastric cancer is a major public health concern due to the many deaths it is associated with. H. pylori is present in almost all gastric cancer patients; thus, it is fundamental to understand how H. pylori is implicated in the etiology of gastric cancer. The research in this paper is primarily based on studies acquired from Touro College Online Libraries. The bacteria have the means to survive the harsh environment of the stomach by creating a safe microenvironment and propelling themselves toward safer territory. If the bacteria attach to host cells, H. pylori injects cytotoxin-associated protein A (CagA) and vacuolating …

Software Choice And Sequencing Coverage Can Impact Plastid Genome Assembly–A Case Study In The Narrow Endemic Calligonum Bakuense, Eka Giorgashvili, Katja Reichel, Calvinna Caswara, Vuqar Kerimov, Thomas Borsch, Michael Gruenstaeudl

Biological Sciences Faculty Publications

Most plastid genome sequences are assembled from short-read whole-genome sequencing data, yet the impact that sequencing coverage and the choice of assembly software can have on the accuracy of the resulting assemblies is poorly understood. In this study, we test the impact of both factors on plastid genome assembly in the threatened and rare endemic shrub Calligonum bakuense. We aim to characterize the differences across plastid genome assemblies generated by different assembly software tools and levels of sequencing coverage and to determine if these differences are large enough to affect the phylogenetic position inferred for C. bakuense compared to congeners. …

Maternal Stress And Excessive Weight Gain In Infancy, Katelyn Fox, Maya Vadiveloo, Karen Mccurdy, Sara E. Benjamin-Neelon, Truls Østbye, Alison Tovar

Nutrition Faculty Publications

Rapid weight gain in infancy increases the risk of developing obesity early in life and contributes significantly to racial and ethnic disparities in childhood obesity. While maternal perceived stress is associated with childhood obesity, little is known about the impact it has on infant weight gain. Therefore, this study explores the impact of maternal perceived stress on change in weight-for-length (WFL) z-scores and the risk of rapid weight gain in infancy. We conducted a secondary data analysis of the longitudinal Nurture birth cohort (n = 666). Most mothers in the cohort were non-Hispanic/Latinx Black (71.6%). About one-half of mothers had …

Effect Of Nest Box Temperature Mitigation Treatments On Nest Success And Nestling Condition In A Southeastern Population Of Eastern Bluebirds (Sialia Sialis), Christopher G. Horacek, Katie Stumpf, Wayne Powell

Graduate Research Showcase

Understanding behavioral responses of wildlife to climate change will be important as global temperatures continue to rise. Effects of rising temperatures may impact many species, including those that breed in seemingly protected nests, such as cavity nesting birds. Variations in nest cavity microclimate during the early development of secondary cavity nesting passerines may affect the growth of offspring and impact nesting success and survival. We examined the effect of two heat mitigation treatments (white exterior, n=11, and an internal foil heat shield, n=16) and nest box opening orientation (north, south, east, west) on internal nest box temperatures and the effect …

On Solving Partial Differential Equations By A Coupling Of The Homotopy Perturbation Method And A New Integral Transform, Inas A. A., E. E. Eladdad Jan 2022

On Solving Partial Differential Equations By A Coupling Of The Homotopy Perturbation Method And A New Integral Transform, Inas A. A., E. E. Eladdad

Applied Mathematics & Information Sciences

In this work, we use a combination between a new integral transform and the homotopy perturbation method. This combination presents an accurate methodology to obtain an exact and numerical solutions for linear and nonlinear partial differential equations. The aim of using this new integral transform is to overcome the deficiency. It is mainly caused by unsatisfied conditions in the other semi-analytical methods such as HPM, VIM, and ADM. More than, this new method appears more applicable, it needs fewer computations. As in the provided numerical example, this method can be used in engineering computations.
