Incidence Of Responders Vs Non-Responders With Sprint Interval Training, Kyle Schulhauser

Theses and Dissertations (Comprehensive)

The current study examined the incidence of non-response to a traditional 30:240 s sprint interval training (SIT) protocol, as well as for 2 modified SIT protocols of 15:120 s, and 5:40 s over 4 wk of training in 84 recreationally active males and females (52m, 32f). Pre- and post- testing measures included: aerobic capacity (V̇O_2max), aerobic performance (5-km time trial), and anaerobic capacity (30 s sprint). Non-response was determined using 2x typical error for each variable. Chi square analysis indicated a significant difference (P = 0.032) in the frequency of non-responders for aerobic performance where the 30:240 group …

The Use Of Public Consultation To Construct Sex Work Related Policies, Ryan Horan

Theses and Dissertations (Comprehensive)

The present study is a qualitative analysis of the Online Public Consultation of Prostitution -Related Offences (OPCPRO), conducted by the Canadian Department of Justice in 2014. This research describes themes that arose within the discourses of respondents to the OPCPRO, and offers a critical examination of the use of online consultations in the production of public policy. I argue that respondents to the OPCPRO, regardless of their support or opposition for criminalization of sex work, strategically draw on values echoed within the Charter of Rights and Freedoms to frame their policy propositions as consistent with sex workers individual rights. I …

Examining The Potential Involvement Of Sex Hormones On Appetite Regulation In Females Across The Menstrual Cycle, Sara Cabral Moniz

Theses and Dissertations (Comprehensive)

Appetite regulation has exclusively been examined during the follicular phase (FP) of the menstrual cycle, and it remains unclear whether the greater levels of estradiol (E₂) and progesterone (P₄) in the luteal phase (LP) affect this process. Thus, the purpose of this study was to utilize vigorous-intensity continuous training (VICT) as a method to modulate plasma concentrations of E₂ and P₄ and examine their associations with post-exercise alterations in acylated ghrelin, peptide tyrosine-tyrosine_3-36 (PYY_3-36), active glucagon like peptide-1 (GLP-1), subjective appetite perceptions, and energy intake across the menstrual cycle. Eleven women …

Expression, Purification, Functional Characterization And Crystallization Of Three Porphyromonas Gingivalis Gene Products, Katarina Mandic

Theses and Dissertations (Comprehensive)

Dental biofilms are coupled polymicrobial aggregates that have attached to solid surfaces in the oral cavity. These collections of microorganisms are known to cause periodontal diseases that commence as localized inflammation of the gingiva and if untreated, eventually lead to irreversible alveolar bone resorption and tooth loss. Porphyromonas gingivalis is one of three periodontal pathogens that make up the “Red Complex”; a bacterial consortium responsible for the production of polysaccharide-rich biofilms that are essential to the inception and progression of periodontal disease. The dysbiosis and destructive inflammation caused by these organisms propel a self-sustained feed-forward loop that perpetuates periodontal disease. …

Second Language Acquisition And Acculturation Differences Between Immigrants And Refugees, Ali Jasemi

Theses and Dissertations (Comprehensive)

The main difference between refugees and immigrants lies in the reason for their migration. Economic immigrants migrate to other countries voluntarily, while refugees are forced to leave their countries due to fear of death or persecution (UNHCR, 2018). Such fears may lead to psychological trauma among refugees. Research has shown that the presence of trauma can negatively impact language learning (Iversen, Sveaass, & Morken, 2014), which may have important implications for both second language (L2) acquisition and acculturation, particularly in refugees. In addition, strong linguistic abilities in a first language (L1) may be beneficial to acquire other languages (Cook, 2003). …

Environmental Factors Associated With Benthic Macroinvertebrate Communities In Arctic Lakes, Northwest Territories, Rachel Cohen

Theses and Dissertations (Comprehensive)

Lake water quality and the macroinvertebrate communities in Arctic regions are threatened by increased development and climate change. In order to understand how macroinvertebrate communities may respond to their changing environment, I performed a biological and water quality survey of 46 Arctic lakes located in the Gwich’in Settlement Area and the Inuvialuit Settlement Region of the Northwest Territories. Using these survey data, I performed two interrelated studies that asked: 1) how artificial pit lakes associated with gravel extraction for road development compared with natural lakes in terms of their water quality, morphometry, and macroinvertebrate communities; and 2) how water quality …

Older Adults’ Social Networks And The Role Of A Telephone Helpline Program, Harmanpreet (Preet) Chauhan

Theses and Dissertations (Comprehensive)

Over the past century, advances in health care, higher levels of education, and improved living conditions have resulted in increased human life expectancy. However, with longer life expectancy comes potential challenges to quality of life, as individuals may face numerous transitions in older age: children leaving home, employment to retirement, or physical declines possibly leading to lack of mobility. As a result, older adults may experience social isolation and difficulty in building new relationships. This is problematic, as lack of social connection is a strong predictor of lower physical and mental health (Fiori & Jager, 2012; Fiori, Smith, & Antonucci, …

Exploring The Personhood And Citizenship Of Persons With Disabilities Among Konkombas In Rural Ghana, Festus Moasun

Theses and Dissertations (Comprehensive)

Persons with disabilities (PWDs) are susceptible to various forms of mistreatments, particularly in the developing world, such that their personhoods are called to question. It was for this purpose that I set out to explore the personhood and citizenship of PWDs in rural Ghana. I used the constructivist paradigm in addition to the personhood and critical disability theories to guide the study which was conducted using an interpretive phenomenological research approach. To make the findings of the study participant driven, semi-structured interviews were held with PWDs. The findings revealed personhood to be perceived in a rank order of three semi-fluid …

Aryl Hydrocarbon Receptor-Mediated Activity Of Gas-Phase Ambient Air Derived From Passive Sampling And An In Vitro Bioassay, Carrie A. Mcdonough, Diana G. Franks, Mark E. Hahn, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

The gaseous fraction of hydrophobic organic contaminants (HOCs) in ambient air appears to be responsible for a significant portion of aryl hydrocarbon receptor (AhR)‐mediated activity, but the majority of compounds contributing to this activity remain unidentified. This study investigated the use of polyethylene passive samplers (PEs) to isolate gaseous HOCs from ambient air for use in in vitro bioassays and to improve our understanding of the toxicological relevance of the gaseous fraction of ambient air in urban and residential environments. Concentrations of polycyclic aromatic hydrocarbons (PAHs) and organic flame retardants (OFRs) were measured in PE extracts. Extracts were also analyzed …

Organophosphate Flame Retardants In The Indoor And Outdoor Dust And Gas-Phase Of Alexandria, Egypt, Mohammed A. Khairy, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Little is known about the presence of organophosphate flame retardants (OPFRs) as a substitute for polybrominated diphenyl ethers in developing countries. This study investigated - for the first time - concentrations, sources and exposure levels of OPFRs in the indoor and outdoor environments of Alexandria, Egypt, in dust and gas-phase samples. Passive samplers were deployed (n = 78) to determine gaseous concentrations, and various dust samples were collected from apartments (n = 25), working places (n = 14), cars (n = 18), and outdoors (OD, n = 30). Indoor concentrations (air: 7.0–64 pg/m³; dust: 150–1850 ng/g) were significantly …

Passive Sampling Of Persistent Organic Pollutants In Four Coastal Aquatic Systems Of Puerto Rico: A Pilot Study, Carlos J. Rodríguez-Sierra, David Adelman, Šimon Vojta, Imar Mansilla-Rivera, Rainer Lohmann

Graduate School of Oceanography Faculty Publications

Little is known about the presence and effects of polychlorinated biphenyls (PCBs) and organochlorine pesticides (OCPs) in Puerto Rico’s waters. Four coastal aquatic systems were investigated using low-density polyethylene passive sampling for PCBs and OCPs in water and its overlying air. The highest total freely dissolved and gaseous concentrations of PCBs were found in Guánica Bay, with 4000 pg/L and 270 pg/m³, respectively. Five OCPs were detected, mainly in water, with greatest concentrations (pg/L) in Guánica Bay: α-HCH (7400), p,pʹ-DDE (390), aldrin (2000), dieldrin (420), and endrin (77). The compound α-HCH was also measured at elevated water concentrations …

Poly- And Perfluoroalkyl Substances In Seawater And Plankton From The Northwestern Atlantic Margin, Xianming Zhang, Rainer Lohmann, Elsie M. Sunderland

Graduate School of Oceanography Faculty Publications

The ocean is thought to be the terminal sink for poly- and perfluoroalkyl substances (PFAS) that have been produced and released in large quantities for more than 60 years. Regulatory actions have curbed production of legacy compounds such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), but impacts of regulations on PFAS releases to the marine environment are poorly understood. Here, we report new data for 21 targeted PFAS in seawater and plankton from the coast, shelf, and slope of the Northwestern Atlantic Ocean. We find strong inverse correlations between salinity and concentrations of most PFAS, indicating that ongoing continental …

Crystal Structure Of Vapbc-1 From Nontypeable Haemophilus Influenzae And The Effect Of Pin Domain Mutations On Survival During Infection, Ashley L. Molinaro, Maithri M. Kashipathy, Scott Lovell, Kevin P. Battaile, Nathan P. Coussens, Min Shen, Dayle A. Daines

Biological Sciences Faculty Publications

Toxin-antitoxin (TA) gene pairs have been identified in nearly all bacterial genomes sequenced to date and are thought to facilitate persistence and antibiotic tolerance. TA loci are classified into various types based upon the characteristics of their antitoxins, with those in type II expressing proteic antitoxins. Many toxins from type II modules are ribonucleases that maintain a PilT N-terminal (PIN) domain containing conserved amino acids considered essential for activity. The vapBC (virulence-associated protein) TA system is the largest subfamily in this class and has been linked to pathogenesis of nontypeable Haemophilus influenzae (NTHi). In this …

Demographic Response Of The Gambian Gerbil To Seasonal Changes In Savannah Fallow Fields, Safianu Rabiu, Robert K. Rose

Biological Sciences Faculty Publications

The Savannah gerbil, Gerbilliscus gambianus (Muridae: Gerbillinae) is important to the ecological relations of the dry grassland ecosystem of West Africa, as well as, being a zoonotic agent of human diseases and po-tential crop pest. We examined the impact of seasonal changes on the population dynamics of G. gambianus in northern Nigeria, by completing population estimates using capture–mark–recapture (CMR) and indirect population density indices (PDI) methods. The latter included fecal pellet counts and limited spotlightening. During 1990–1992 we collected both CMR and PDI data, and established their relationship by regression, thus calibrating the PDI values to CMR estimator. We also …

Biological Sciences Faculty Publications

Background

Despite decades of use of control programs, schistosomiasis remains a global public health problem. To further reduce prevalence and intensity of infection, or to achieve the goal of elimination in low-endemic areas, there needs to be better diagnostic tools to detect low-intensity infections in low-endemic areas in Brazil. The rationale for development of new diagnostic tools is that the current standard test Kato-Katz (KK) is not sensitive enough to detect low-intensity infections in low-endemic areas. In order to develop new diagnostic tools, we employed a proteomics approach to identify biomarkers associated with schistosome-specific immune responses in hopes of developing …

Twenty-five patients with Sjögren's syndrome (SjS), 29 with rheumatoid arthritis (RA), and 38 patients with systemic lupus erythematosus (SLE) and 53 healthy controls (NC) were also included. ELISAs with high and low salt …

Prime-Boost Vaccine Regimen For Sjtpl And Sjc23 Schistosome Vaccines, Increases Efficacy In Water Buffalo In A Field Trial In China, Akram A. Da'dara, Changlin Li, Xinling Yu, Mao Zheng, Jie Zhou, Lisa M. Shollenberger, Yue-Sheng Li, Donald A. Ham

Biological Sciences Faculty Publications

Schistosomiasis remains a serious zoonotic disease in China and the Philippines. Water buffalo and cattle account for the majority of transmission. Vaccination of water buffalo is considered a key strategy to reduce disease prevalence. Previously, we showed that vaccination of water buffalo with SjC23 or SjCTPI plasmid DNA vaccines, induced 50% efficacy to challenge infection. Here, we evaluated several parameters to determine if we can develop a two dose vaccine that maintains the efficacy of the three dose vaccine. We performed four trials evaluating: (1) lab produced vs. GLP grade vaccines, (2) varying the time between prime and boost, (3) …

Merritt, Wan Lu Lin, Xiaoying Zhang, Charalambos Solomides, Ifeyinwa Nwaneshiudu, John Gaughan, Dimitri S. Monos, Emilia L. Oleszak, Chris D. Platsoucas

Biological Sciences Faculty Publications

Abdominal aortic aneurysm (AAA) is a life-threatening immunological disease responsible for 1 to 2% of all deaths in 65 year old or older individuals. Although mononuclear cell infiltrates have been demonstrated in AAA lesions and autoimmunity may be responsible for the initiation and account for the propagation of the disease, the information available about the pathogenesis of AAA is limited. To examine whether AAA lesions from patients with AAA contain clonally expanded α-chain TCR transcripts, we amplified by the non-palindromic adaptor-PCR (NPA-PCR)/Vα-specific PCR and/or the Vα-specific PCR these α-chain TCR transcripts. The amplified transcripts were cloned and sequenced. Substantial proportions …

Mapping Status And Conservation Of Global At-Risk Marine Biodiversity, Casey C. O'Hara, Juan Carlos Villaseñor-Derbez, Gina M. Ralph, Benjamin S. Halpern

Biological Sciences Faculty Publications

To conserve marine biodiversity, we must first understand the spatial distribution and status of at‐risk biodiversity. We combined range maps and conservation status for 5,291 marine species to map the global distribution of extinction risk of marine biodiversity. We find that for 83% of the ocean, >25% of assessed species are considered threatened, and 15% of the ocean shows >50% of assessed species threatened when weighting for range‐limited species. By comparing mean extinction risk of marine biodiversity to no‐take marine reserve placement, we identify regions where reserves preferentially afford proactive protection (i.e., preserving low‐risk areas) or reactive protection (i.e., mitigating …

The Positive Predictive Value Of The Phq-2 As A Screener For Depression In Spanish-Speaking Latinx, English-Speaking Latinx, And Non-Latinx White Primary Care Patients., Ana J. Bridges, Aubrey R. Dueweke, Elizabeth A. Anastasia, Juventino Hernandez Rodriguez

Psychological Science Faculty Publications

Although the Patient Health Questionnaire 2 (PHQ-2) is frequently used to screen for depressive disorders in primary care patients, there is little information about its psychometric properties in diverse populations. The present study evaluated the positive predictive value (PPV) of the PHQ-2 in three groups of primary care patients at a federally qualified health center (78% female, M age = 42.73 years, range 18–78): Spanish-speaking Latinxs (n = 490), English-speaking Latinxs (n = 134), and non-Latinx Whites (n = 690). Universal screening with the PHQ-2 of consecutive adult primary care patients took place during a 5-month period. Any “yes” response …

Fall Detection Using Channel State Information From Wifi Devices, D.M Sameera Palipana

PhDs

Falls among the independently living elderly population are a major public health worry, leading to injuries, loss of confidence to live independently and even to death. Each year, one in three people aged 65 and older falls and one in five of them suffers fatal or non fatal injuries. Therefore, detecting a fall early and alerting caregivers can potentially save lives and increase the standard of living. Existing solutions, e.g. push-button, wearables, cameras, radar, pressure and vibration sensors, have limited public adoption either due to the requirement for wearing the device at all times or installing specialized and expensive infrastructure. …

Structural Investigation Of Bcsc: Insight Into Periplasmic Transport During Cellulose Export, William Scott, Joel T. Weadge

Theses and Dissertations (Comprehensive)

A biofilm can be defined by a community of microbes coexisting within a self-produced protective polymeric matrix. Exopolysaccharide (EPS) is a key component in biofilms and a contributor to their virulence and pathogenicity. The cellulose bacterial synthesis complex is one such EPS system that is found in many Enterobacteriaceae,including Escherichia coli and Salmonella spp., and is responsible for the production and secretion of the EPS cellulose. BcsC is the periplasmic protein responsible for the export of the exopolysaccharide cellulose and was the focus of this research. Sequence homology comparisons and structural predictions between BcsC, and the previously characterized alginate …

Marjolin's Tumor Complicating Chronic Periprosthetic Infection Of A Total Knee Arthroplasty, Timothy Horan, Matthew T. Wallace, Albert J. Aboulafia, Janet D. Conway

Orthopedic Surgery Resident Research

Marjolin's tumor is a term used to describe a malignancy developing in the setting of a chronic wound, infection, or other tissue subject to chronic inflammatory changes. These malignancies usually present after many years of chronicity, and can range from lower grade basal cell carcinomas to high-grade sarcomas. We present the case of a squamous cell carcinoma that developed within a chronic periprosthetic infection of a total knee arthroplasty of 7 years duration. The intra-articular location, association with an orthopaedic implant, and brief latency period are all unique features of this case.
