The concentration of dissolved organic nitrogen (DON) is increasing in many northern hemisphere lakes, yet its use by phytoplankton and fate in the environment seldom have been quantified. We conducted 1 week, in situ, microcosm incubations across 25 lakes in northeastern North America to understand how DON, dissolved inorganic nitrogen (DIN), and dissolved inorganic phosphorus (P) affected phytoplankton biomass. In addition, we tested whether lakes were limited by single macronutrients (N or P) or colimited by both. Phytoplankton biomass in 80% of lakes responded similarly to DON and DIN additions. Of the lakes where N form produced differential responses, the …

The Influences Of The Religious Tradition Of Ramadan On Dietary Intake And Body Composition In Adolescent Athletes: An Evidence-To-Practice Review, Regina A. Duncan, Shannon E. Ryan, Erin M. Watlington, Nancy A. Uriegas, Zachary K. Winkelmann

Clinical Practice in Athletic Training

When participating in the religious tradition of Ramadan, the body is subject to changes that adjust an athlete's regimented dietary intake. The guiding systematic review and meta-analysis were conducted to gather the results of the limited research on the effect of Ramadan observance on body mass, body composition, and dietary intake in adolescent athletes. Data were extracted from two different databases, and a search through several journals exploring body mass and/or body composition and/or dietary intake was conducted. The methodological quality of each study was assessed via QualSyst. No significant differences were found when comparing the body mass, body composition, …

Healthcare Providers’ Knowledge And Implementation Of Pneumococcal Vaccination Recommendations, Lara Blake, Pam White

MSN Research Projects

Streptococcal pneumoniae is a vaccine preventable disease but remains a leading cause of disease and death in the United States. In 2016, Streptococcal pneumoniae was responsible for 1.2 million deaths in over 195 countries. The illness is attributed to patients having invasive diseases, comorbid diseases, disability and death. The number of adults contracting Streptococcal pneumonia could be lowered dramatically with the use of proper vaccination, which is readily available. In 2022, the Center for Disease Control and the Advisory Committee on Immunization Practices (ACIP) release a new timing schedule and guidelines regarding the vaccination for pneumonia in the adult population. …

Eating Change: A Critical Autoethnography Of Community Gardening And Social Identity, Jessica Gerrior

Antioch University Dissertations & Theses

Community gardening efforts often carry a social purpose, such as building climate resilience, alleviating hunger, or promoting food justice. Meanwhile, the identities and motivations of community gardeners reflect both personal stories and broader social narratives. The involvement of universities in community gardening projects introduces an additional dimension of power and privilege that is underexplored in scholarly literature. This research uses critical autoethnography to explore the relationship of community gardening and social identity. Guided by Chang (2008) and Anderson and Glass-Coffin (2013), a systematic, reflexive process of meaning-making was used to compose three autoethnographic accounts. Each autoethnography draws on the author’s …

Deconstructing Orthorexia In An Age Of Healthism And Social Media, Maddison Paul

Antioch University Dissertations & Theses

Orthorexia, a pathological fixation with healthy eating, has recently emerged as a construct of interest in the field of clinical psychology. Despite its growing recognition, the origin of this construct remains unclear. This dissertation aims to contribute to the understanding of orthorexia by examining its emergence and contextual factors through a constructivist lens. The study found that the cultural, economic, and moralistic landscape of healthism and social medially have played a role in the development of orthorexia. The dominant clinical perspective of orthorexia was also deconstructed, revealing potential biases that may lead to pathologizing the experiences of those who demonstrate …

Safety Procedures To Work With West Nile Virus In Biosafety Level 3 Facilities, Freedom M Green, Shannon E Ronca

Faculty, Staff and Students Publications

West Nile virus (WNV) can cause severe and sometimes fatal disease, but we do not have treatments or therapeutics to manage these outcomes. Since its introduction to the USA in 1999, WNV has been handled in a biosafety level 3 laboratory to decrease risk to researchers, requiring strict safety protocols and important considerations with planning experiments. Recent changes in US guidelines suggest that WNV can be handled at a lower biosafety level due to its endemicity in the USA and generally minor symptoms, but some research still requires the use of the agent at biosafety level 3. This chapter will …

Cerebral Microdialysis And Glucopenia In Traumatic Brain Injury: A Review, Himanshu Sharma, John P Mcginnis, Katherine E Kabotyanski, Shankar P Gopinath, Jerry C Goodman, Claudia Robertson, Jovany Cruz Navarro

Faculty, Staff and Students Publications

Traditionally, intracranial pressure (ICP) and partial brain tissue oxygenation (PbtO2) have been the primary invasive intracranial measurements used to guide management in patients with severe traumatic brain injury (TBI). After injury however, the brain develops an increased metabolic demand which may require an increment in the oxidative metabolism of glucose. Simultaneously, metabolic, and electrical dysfunction can lead to an inability to meet these demands, even in the absence of ischemia or increased intracranial pressure. Cerebral microdialysis provides the ability to accurately measure local concentrations of various solutes including lactate, pyruvate, glycerol and glucose. Experimental and clinical data demonstrate that such …

Cranberry Vine And Its Effects On The Periparturient Ovine And Her Offspring, Delaney Smith

Open Access Dissertations

Gastrointestinal nematodes (GIN) are a major health concern globally, particularly for small ruminant producers. The most deadly of these GIN is an anemia-inducing parasite called Haemonchus contortus. Infections of H. contortus are most severe during what's known as the periparturient period (PPP), which is the last 6 weeks of gestation and first 8 weeks of lactation in maternal animals. Widespread genetic resistance of H. contortus to the traditionally used chemical dewormers have led producers and researchers alike to turn to the plant kingdom for answers. Plant based compounds have been used as bioactive compounds for centuries to cure a …

Elucidating The Mechanisms Of Stress Tolerance In Reef-Building Coral Holobionts, Emma Strand

Open Access Dissertations

Coral reefs worldwide are threatened by climate change effects like increasing ocean warming and ocean acidification. These increased pressures cause a dysbiosis between the coral host, algal endosymbionts, and associated coral microbiome that results in the coral host expelling algal endosymbionts, leaving the coral host with a stark white ‘bleached’ appearance. Without their endosymbionts, coral hosts are forced to sustain themselves energetically with heterotrophy instead of relying on the autotrophic carbon and energy sources that once came from the algal endosymbionts. When this response, termed ‘coral bleaching’, happens reef-wide during an extreme wave of increased ocean temperatures, this is called …

The Effect Of Acceptance And Commitment Therapy On Value Consistency During A Weight Loss Program, Leah Dorfman

Open Access Dissertations

In the last decade, the prevalence of obesity has increased significantly in populations worldwide. It is well established that overweight and obesity are associated with a host of deleterious health consequences. Standard Behavioral Therapy (SBT) for weight loss has been demonstrated to yield only modest outcomes with poor long-term maintenance. Therefore, efforts must be made to improve upon what is currently considered to be best practices in weight loss interventions, especially with a goal of improving retention and long-term maintenance. Acceptance and Commitment Therapy (ACT) is a behavioral and cognitive intervention that implements both acceptance and mindfulness processes, and commitment …

Biochemical And Genetic Mechanisms Underpinning Escherichia Coli Cell Cycle And Growth Transitions, Josiah Morrison

Open Access Dissertations

Bacterial cell division and the decision to divide is a process that requires a wide variety of factors. In bacterial cells, such as the widely studied Escherichia coli, a large protein complex, termed the Z-ring, assembles at midcell to enable division. The Z-ring is subject to many regulators which govern the spatiotemporal positioning of the ring. The Z-ring is made up of the eukaryotic tubulin homolog FtsZ, which polymerizes to recruit division proteins to the midcell. FtsZ polymers are tethered to the cytoplasmic membrane by the actin homolog FtsA. Together, FtsZ and FtsA act as the first step in …

Adapting A Mobile App To Support Patients With Anorexia Nervosa Following Post-Acute Care: Perspectives From Eating Disorder Treatment Center Stakeholders, Anneliese Haas, Agatha A Laboe, Claire G Mcginnis, Marie-Laure Firebaugh, Jillian Shah, Anna M Bardone-Cone, Kathleen M Pike, C Barr Taylor, Denise E Wilfley, Ellen E Fitzsimmons-Craft

2020-Current year OA Pubs

INTRODUCTION: Anorexia nervosa (AN) is a harmful, life-threatening illness. Patients with severe AN often receive acute treatment but, upon discharge, experience high relapse rates. Evidence-based, outpatient treatment following acute care is critical to preventing relapse; however, numerous barriers (e.g., location, financial limitations, low availability of providers) preclude individuals from accessing treatment. mHealth technologies may help to address these barriers, but research on such digital approaches for those with AN is limited. Further, such technologies should be developed with all relevant stakeholder input considered from the outset. As such, the present study aimed to garner feedback from eating disorder (ED) treatment …

Women's Empowerment And Child Nutrition In A Context Of Shifting Livelihoods In Eastern Oromia, Ethiopia, Karah Mechlowitz, Mark J Manary, Et Al.

2020-Current year OA Pubs

Agriculture, and particularly livestock and animal source foods, has been closely linked to improvements in human nutrition. Production, income, and women's empowerment improve household food security and child nutritional outcomes in interacting ways. Khat production in Eastern Ethiopia is changing the economic and livelihood landscape for communities that have traditionally relied upon small-scale mixed agriculture and livestock production. How this shifting livelihood landscape and the empowerment of women in these communities are affecting nutritional outcomes has not been investigated. Using cross-sectional data collected during formative research for the Campylobacter Genomics and Environmental Enteric Dysfunction (CAGED) project, we developed models to …

Vancomycin-Induced Gut Microbial Dysbiosis Alters Enteric Neuron-Macrophage Interactions During A Critical Period Of Postnatal Development, Ellen Merrick Schill, Elisabeth L Joyce, Alexandria N Floyd, Sreeram Udayan, Brigida Rusconi, Shreya Gaddipati, Bibiana E Barrios, Vini John, Mitchell E Kaye, Devesha H Kulkarni, Jocelyn T Pauta, Keely G Mcdonald, Rodney D Newberry

2020-Current year OA Pubs

Vancomycin is a broad-spectrum antibiotic widely used in cases of suspected sepsis in premature neonates. While appropriate and potentially lifesaving in this setting, early-life antibiotic exposure alters the developing microbiome and is associated with an increased risk of deadly complications, including late-onset sepsis (LOS) and necrotizing enterocolitis (NEC). Recent studies show that neonatal vancomycin treatment disrupts postnatal enteric nervous system (ENS) development in mouse pups, which is in part dependent upon neuroimmune interactions. This suggests that early-life antibiotic exposure could disrupt these interactions in the neonatal gut. Notably, a subset of tissue-resident intestinal macrophages, muscularis macrophages, has been identified as …

Microbiome-Targeting Therapies In The Neonatal Intensive Care Unit: Safety And Efficacy, Anna Deveaux, Jian Ryou, Gautam Dantas, Barbara B Warner, Phillip I Tarr

2020-Current year OA Pubs

Microbiome-targeting therapies have received great attention as approaches to prevent disease in infants born preterm, but their safety and efficacy remain uncertain. Here we summarize the existing literature, focusing on recent meta-analyses and systematic reviews that evaluate the performance of probiotics, prebiotics, and/or synbiotics in clinical trials and studies, emphasizing interventions for which the primary or secondary outcomes were prevention of necrotizing enterocolitis, late-onset sepsis, feeding intolerance, and/or reduction in hospitalization length or all-cause mortality. Current evidence suggests that probiotics and prebiotics are largely safe but conclusions regarding their effectiveness in the neonatal intensive care unit have been mixed. To …
