Abstract

Honey bees, Apis mellifera, are a globally significant pollinator species and are currently in decline, with losses attributed to an array of interacting environmental stressors. Extremely low frequency electromagnetic fields (ELF EMFs) are a lesser-known abiotic environmental factor that are emitted from a variety of anthropogenic sources, including power lines, and have recently been shown to have a significant impact on the cognitive abilities and behaviour of honey bees. Here we have investigated the effects of …

Phenotypically Plastic Responses To Predation Risk Are Temperature Dependent, Thomas M. Luhring, Janna M. Vavra, Clayton E. Cressler, John Delong

School of Biological Sciences: Faculty Publications

Predicting how organisms respond to climate change requires that we understand the temperature dependence of fitness in relevant ecological contexts (e.g., with or without predation risk). Predation risk often induces changes to life history traits that are themselves temperature dependent. We explore how perceived predation risk and temperature interact to determine fitness (indicated by the intrinsic rate of increase, r) through changes to its underlying components (net reproductive rate, generation time, and survival) in Daphnia magna. We exposed Daphnia to predation cues from dragonfly naiads early, late, or throughout their ontogeny. Predation risk increased r differentially across temperatures …

Barrier Membranes Used In Guided Bone Regeneration: A Review, Riad Fardoun

International Arab Journal of Dentistry

Barrier membranes can be mainly classified into bio-resorbable and non-resorbable membranes. Each one of them has its own properties; including biocompatibility, appropriate barrier features (mechanical prevention of soft tissue proliferation), tissue integration, immunologic neutrality, preservation of the space for new alveolar bone, and simplicity of application. Such membrane must hold out against the masticatory forces and tissue tension of the flap and prevent the collapse of soft tissues and wound space reduction. The property of integration into the tissue guarantees wound stabilization and inhibits epithelial migration. The aim of this review was to compare and evaluate the influence of bio-resorbable …

Effect Of A Novel Thermal Treatment On Rough Titanium Implant Surfaces – "In Vitro" Evaluation, Rahil Douweihy, Carole Chakar, Georges Hilal, Zeina Al Majzoub

International Arab Journal of Dentistry

Current trends in modern biomedical research target the development of dental implant surfaces that are more biocompatible, and highly osteoconductive/ osteoinductive to achieve faster osseointegration and stronger bone-to-implant interface, especially under poor local and systemic clinical conditions. Heat treatment has been suggested to alter surface characteristics and result in improved biological response. The objectives of the present in vitro study are to evaluate the impact of a novel heat treatment method of rough titanium implants on cell viability, cell proliferation, and alkaline phosphatase activity. Six groups of grade 4 commercially pure titanium (Ti) discs measuring 6 mm in diameter and …

Regulation Of The Microtubule Cytoskeleton And Cell Wall Development In Arabidopsis Thaliana, Christy J. Fornero

Theses and Dissertations

Regulation of the cortical microtubule cytoskeleton is critical for organized plant cell division. Arabidopsis ton1 and ton2 mutants display random cell division plane placement and lack the plant-specific cortical microtubule array that encircles the nucleus prior to mitosis. In wild type plants, this preprophase band (PPB) of cortical microtubules precisely marks the future division plane. The specific roles of TON1 and TON2 in PPB formation are not yet known. It is suspected that TON1 Recruiting Motif (TRM) proteins may be involved in TON1 and TON2 recruitment to the PPB. Here we describe results for the targeted disruption of a group …

Piezoelastic Pvdf/Tpu Nanofibrous Composite Membrane: Fabrication And Characterization, Eman Elnabawy, Ahmed H. Hassanin, Nader Shehata, Anton Popelka, Remya Nair, Saifallah Yousef, Ishac Kandas

Biology Faculty Publications

Poly (vinylidene fluoride) nanofibers (PVDF NFs) have been extensively used in energy harvesting applications due to their promising piezoresponse characteristics. However, the mechanical properties of the generated fibers are still lacking. Therefore, we are presenting in this work a promising improvement in the elasticity properties of PVDF nanofibrous membrane through thermoplastic polyurethane (TPU) additives. Morphological, physical, and mechanical analyses were performed for membranes developed from different blend ratios. Then, the impact of added weight ratio of TPU on the piezoelectric response of the formed nanofibrous composite membranes was studied. The piezoelectric characteristics were studied through impulse loading testing where the …

A Phonetic Distance Approach To Intelligibility Between Mam Regional Dialects, Megan Simon

Master's Theses

Mam, an indigenous Mayan language spoken primarily in Guatemala, has considerable internal diversity among its regional dialects. The purpose of this thesis is to estimate their varying degrees of intelligibility and to present groups of dialects whose speakers can be reasonably expected to understand one another. The analysis consists of two parts, the computation of a phonetic distance network and a series of sociocultural interviews. Phonetic distance was measured by Levenshtein distance between cognates in word lists and analyzed with a Neighbor-Net network. Interviews with Mam speakers focused on subjective judgments of intelligibility, contact, and social attitudes. Four main dialect …

Does Time Spent Using Social Media Impact Mental Health?: An Eight Year Longitudinal Study, Sarah M. Coyne, Adam A. Rogers, Jessica D. Zurcher, Laura Stockdale, Mccall Booth

Faculty Publications

Many studies have found a link between time spent using social media and mental health issues, such as depression and anxiety. However, the existing research is plagued by cross-sectional research and lacks analytic techniques examining individual change over time. The current research involves an 8-year longitudinal study examining the association between time spent using social media and depression and anxiety at the intra-individual level. Participants included 500 adolescents who completed once-yearly questionnaires between the ages of 13 and 20. Results revealed that increased time spent on social media was not associated with increased mental health issues across development when examined …

“Go Sue Yourself!” Imagining Intrapersonal Liability For Negligently Self-Inflicted Harms, Lars Noah

Florida Law Review

Are “self-inflicted” harms actionable? Courts increasingly have allowed victims to identify other (typically unrelated) parties that may share responsibility for such injuries. Moreover, insofar as judges now also permit lawsuits against closely related parties, they arguably have expanded what it means for a harm to qualify as self-inflicted. Taking these various doctrinal developments to an illogical extreme, this Article asks whether we should just let victims bring tort claims against themselves, understanding that the victims’ own liability insurers represent the intended targets. That this idea is not as crazy as it sounds suggests the extent to which tort law has …

Cash Me Outside–An Alternative To Wasteful Medical Spending In Terminally Ill Patients, Christopher Neal Loy, Jr.

Florida Law Review

The U.S. health care system is an inefficient machine that is burdened by overconsumption and wasteful spending. The system has long defaulted into maximizing the quantity of life over quality—a choice influenced by corporations that stand to profit with every additional procedure. To stymie health care spending and attempt to restore the true cost of treatment to patients, this Note proposes an alternative to how health insurers provide options to terminally ill cancer patients by offering a partial cash rebate to forgo any life-extending measures. The patient would be free to leave his or her legacy, the health insurer would …

The Global Trade Of Cloned Meat, Andrew Jensen Kerr

Florida Law Review

Until now commercial animal cloning has been generally limited to breeding stock. But Xu Xiaochun of the Chinese company Boyalife Genetics plans to mass produce animal clones for direct meat consumption. The research partnership between Boyalife and South Korean firm Sooam Biotech suggests the possibility of an international market for cloned food animals.

Can cloned food imports be rejected by national governments? This Article outlines the relevant considerations, and argues that a revised understanding of the “precautionary principle” can help to reconcile disparate, and perhaps ineffable, goals like producing high-quality meat and maintaining the integrity of the human experience.

Sweet Child O’ Mine: Adult Adoption & Same-Sex Marriage In The Post-Obergefell Era, Robert Keefe

Florida Law Review

Gay and lesbian partners used adult adoption to create family relationships and to ensure inheritance and property rights in the decades before the Supreme Court’s decision in Obergefell v. Hodges legalized same-sex marriage nationwide. Same-sex partners who chose adult adoption as an alternative to marriage before the Obergefell decision must now dissolve the adoption in order to exercise their constitutional right to marry due to state incest laws prohibiting marriages between parents and their adopted children. It is difficult, however, to dissolve an adoption, and anecdotal evidence indicates that some judges have refused to dissolve adoptions between same sex partners. …

Potential Use Of Dopamine And Dopamine Agonists As Angiogenesis Inhibitors In The Treatment Of Cancer, Benjamin Finley, Katherine Liu, Daniel Powell, Jamie Kellner, David H. Kinder

Pharmacy and Wellness Review

In recent years, there have been numerous developments in monoclonal antibodies used as anticancer drugs with a focus on reducing the ability of cancers to metastasize and produce new vasculature. These agents are called angiogenesis inhibitors and although these agents have been proven effective in treating certain types of cancers, production and administration of monoclonal antibodies comes at a steep cost with a severe side effect profile. Under normal physiologic conditions, angiogenesis is an important mechanism to create new blood vessels from preexisting vessels, usually occurring in adults. Tumor cells can hijack the angiogenesis pathway to produce new distant tumors …

New training initiatives and a comprehensive understanding of the overall needs in emergency situations enables pharmacists to utilize their drug knowledge and accessibility to the public to provide vital medical care in stressful situations.

New Cholesterol Guidelines: An Update For Pharmacists, Emily Limberg, Benjamin Finley, Stacy Henthorne, Sarah Kradel, David Bright

Pharmacy and Wellness Review

The American College of Cardiology and American Heart Association published new blood cholesterol guidelines in November 2013. The new guidelines place an emphasis on evidence-based treatment of dyslipidemias and primarily use randomized controlled trials to create recommendations for health care providers. Major changes from the previous guidelines include eliminating low-density lipoprotein goals, the classification of statins by lipid-lowering potential and the creation of four major statin benefit groups. The new guidelines also establish the role of non-statins in dyslipidemias and use the Pooled Cohort Risk Assessment Equations to calculate patients' risk for cardiovascular events and the need for cholesterol-lowering medications. …

Crohn's Disease: Management, Emerging Therapies And The Role Of The Pharmacist, Sarah Turley, Tiffany Kneuss, Lydia Suchecki, Alison Steinbrunner, Kristen Timperman

Pharmacy and Wellness Review

Crohn's disease is a relapsing-remitting disorder of the gastrointestinal tract caused by a mixture of genetic and environmental factors. Pharmacologic treatment of Crohn's disease is patient-specific, and regimens vary widely between individuals. Drug regimens are typically based on 5-aminosalicylate therapy and may include a combination of steroids, histamine 2 receptor antagonists, proton pump inhibitors, immunomodulators, antibiotics, biologic agents and other medications aimed at symptom relief. A new medication, vedolizumab, is currently in phase III clinical trials awaiting U.S. Food and Drug Administration (FDA) approval for use in Crohn's disease. Vedolizumab is an alpha-integrin inhibitor, which is anticipated to have a …

Lbrutinib (Lmbruvica™) For Treatment Of Mantle Cell Lymphoma, Brittany Crowe, Joy Hoffman, Hannah Stewart, Alison Steinbrunner, Mark E. Olah

Pharmacy and Wellness Review

Mantle cell lymphoma (MCL) is a rare and moderately aggressive form of non-Hodgkin's lymphoma (NHL) that predominantly presents at an advanced stage in older males. Patients often present with multiple involvement in the lymph nodes, blood, spleen, bone marrow and gastrointestinal tract (GIT). Some patients may be asymptomatic in early stages or present with an incurable, indolent (slow progressing) form, while other patients display rapid growth of more aggressive lymphomas. Overall survival for patients diagnosed with MCL is four to five years and treatment should be initiated in those who are symptomatic. Mantle cell lymphoma responds well to first-line treatment, …

Answers About The Need For Vitamin D Supplementation, Halle Orlinski, Hannah Stewart, Amanda Lanker, Sarah Kradel, Sandra L. Hrometz

Pharmacy and Wellness Review

Vitamin D has a significant role in bone health, calcium homeostasis, immune function and other biological functions. In our bodies, the main source of vitamin D is linked to our skin's exposure to sunlight. It can also be obtained through foods that contain vitamin D. Despite these two sources, vitamin D supplementation is often necessary. It is available in two forms, cholecalciferol and ergocalciferol as over-the-counter (OTC) products, as well as calcitriol as prescription only. Reasons for vitamin D deficiency include lack of sunlight, poor diet, malabsorption of vitamin D, liver and/or kidney disease. Vitamin D deficiencies lead to diseases …

Achieving Provider Status For Pharmacists, Kasie Bellmann, Alexandra Dimit, Kelsey Weisenburger, Donald L. Sullivan

Pharmacy and Wellness Review

In order to receive payment for medical services through Medicare Part 8, health care professionals must be identified as "providers" under the Social Security Act. Pharmacists currently are not included in the list of providers and, therefore, cannot provide many services to patients. Through their extensive education and training, accessibility and immense trust in their profession, pharmacists are the ideal health care professionals to help expand the continuity of care of our nation's patients. On Jan. 1, 2014, Senate Bill 493 was passed into law recognizing pharmacists in the state of California as providers. With this new legislation, the pharmacists' …

Whooping Cough: A Pharmacist's Role In An Emerging Endemic, Haley Armstrong, Lydia Suchecki, Sarah Lipperman, Taylor Roberson, Andrew M. Roecker

Pharmacy and Wellness Review

Pertussis is an acute infectious disease caused by the organism Bordetella pertussis and characterized by a "whooping cough." Incidence of the disease had declined since the development of a vaccine, but is now increasing in reported cases. This increase has been attributed to both an increased awareness but also surmised to be related to a decrease in vaccinations. The pertussis vaccine is given in conjunction with tetanus and diphtheria vaccines to children before the age of 6 in five separate injections over the course of four to six years. A booster is now recommended for the older child and adults …

In Dependence: Haiti In The Period Of Neoliberalism, Mckenzie Kelly

History in the Making

Haiti is often considered to be one of the least developed and unstable countries in the world today. However, many scholars have failed to look into the cause of Haiti’s lack of development in comparison to other countries in similar situations. While some have addressed the colonial history of Haiti, and others have discussed the role of neoliberalism in Haiti’s development, this paper aims to connect the two ideas. The current predicament that Haiti finds itself in did not occur in a vacuum, but instead was the result of colonial and post-colonial foreign policy, the shift to neoliberal policies following …
