Family Environments And Children's Cognitive Skills: Accounting For Heritable Influences Through Comparing Adopted And Biological Children, Shelby Mae Mcneill

Theses and Dissertations

Utilizing ECLS-K:2011 data, this study compares adopted and biological children to account for the role of heritable characteristics in explaining the relationship between family environments and children's cognitive skills. I find that cognitive skills do not differ across adopted and biological children after adjusting for the systematic differences between them. I also find that the relationship between family environment and children's cognitive skills does not differ across adopted and biological children. Taken together, these results suggest that the relationship between family environment and children's cognitive skills is not spurious.

Marital Quality And Cardiovascular Risk In Women During The Menopausal Transition, Tracy E. Brown

Theses and Dissertations

Marital quality is linked to health benefits for men and women. Although women have less risk factors than men for cardiovascular disease prior to menopause, their risk increases substantially after menopause. The purpose of this study was to assess the impact of marital quality and vasomotor symptoms on cardiovascular risk factors including C-reactive protein (CRP) and carotid intima-media thickness (cIMT) in women before, during, and after the menopausal transition. The final sample consisted of 92 married women between the ages of 40 and 60 years. Hypotheses were tested using hierarchical regression and general linear modeling. Results suggest that greater marital …

The Relationship Between Auditory Habituation And Anxiety In Autism Spectrum Disorder, David Nicholas Top

Theses and Dissertations

Many individuals with autism spectrum disorder (ASD) have atypical sensory processing and behaviors including sensory sensitivity and low registration of sensory stimuli as well as sensory seeking and avoiding behaviors. Additionally, many individuals with ASD have clinically distressing levels of anxiety. Previous research suggests that there is a link between abnormal sensory processing, anxiety, and ASD. The purpose of this study was to experimentally observe auditory sensory processing using pupillometry methods, between ASD, control, and high-anxious control groups. While a difference in tonic pupil size was observed, there were no reactivity or habituation differences between the groups. There were no …

Survivors' Perceptions Of Support Following A Parent's Suicide, Suzanne Nicole Bennett

Theses and Dissertations

Children who experience a parent's death by suicide are a vulnerable population at risk for emotional and mental health issues as well as suicide attempts (Cerel, Fristad, Weller, & Weller, 1999; Kuramoto et al., 2010; Wilcox et al., 2010). Yet, in spite of the knowledge that effective postvention is in reality prevention (Cerel et al. 2008), relatively little is known about these children and adolescents, particularly regarding their experiences following the suicide. The current research study investigated which resources, assistance, and actions of those around the child were perceived as most helpful and unhelpful following the parental suicide. Through semi-structured …

Trauma Therapy For Very Young Children Living In Poverty: A Randomized Controlled Trial, Joanna Ruth Love

Dissertations (1934 -)

This study used a randomized control design with immediate treatment and wait list control conditions to evaluate the efficacy of the New Hope program, a home-based, parent-and-child therapy program that has been developed for very young children living in poverty who experienced one or more potentially traumatizing events. Within a three-phase model of treatment, the New Hope program is designed to establish safety, build the caregiver child relationship, create a nurturing environment, teach coping skills, address trauma-related thoughts and feelings, and develop prosocial skills. Training in this program included discussions regarding the cultural implications of providing therapy services in the …

Redox And Spectroscopic Properties Of Protonated Species Of Iron Porphyrin Nitroxlys And Their Analogues, Md. Hafizur Rahman

Dissertations (1934 -)

Nitrite reduction to ammonia or nitrous oxide involves a series of electron transfer and protonation steps which are carried out by assimilatory or dissimilatory nitrite reductases. In the assimilatory process, nitrite incorporated into the biomass while in the dissimilatory process, it is excreted from the cell and the reaction is a source of energy. The complexes that will be studied in this work are models for assimilatory (siroheme) and dissimilatory (heme d1 ) nitrite reductases. Iron porphyrin nitrosyls were reduced in the presence of weak acids such as phenol and substituted phenols. Voltammetric techniques such as cyclic and rotating ring …

Design And Synthesis Of Selective Estrogen Receptor Β Agonists And Their Pharmacology, K. L. Iresha Sampathi Perera

Dissertations (1934 -)

Estrogens (17β-estradiol, E2) have garnered considerable attention in influencing cognitive process in relation to phases of the menstrual cycle, aging and menopausal symptoms. However, hormone replacement therapy can have deleterious effects leading to breast and endometrial cancer, predominantly mediated by estrogen receptor-alpha (ERα) the major isoform present in the mammary gland and uterus. Further evidence supports a dominant role of estrogen receptor-beta (ERβ) for improved cognitive effects such as enhanced hippocampal signaling and memory consolidation via estrogen activated signaling cascades. Creation of the ERβ selective ligands is challenging due to high structural similarity of both receptors. Thus far, several ERβ …

The Cytotoxic And Genotoxic Effects Of Bisphenol A On Neuronal Cells In Vitro, Shannon O'Sullivan

The Plymouth Student Scientist

Endocrine disrupting chemicals (EDCs) have the potential to cause adverse effects to human health by disrupting normal homeostasis, reproduction, development and behaviour. They can simultaneously act as cytotoxic and genotoxic agents. Bisphenol A (BPA) is a well-documented EDC, widely used in the manufacturing of plastic and epoxy resins. Humans are regularly exposed to this chemical through ingestion of food and beverages. The adverse effects of BPA on reproduction and development have been thoroughly studied. The potential adverse effect of BPA however, on neuronal development has not been entirely explored. In this study, the potential cytotoxic and genotoxic effects of BPA …

Impacts Of Culling Invasive Lionfish (Pterois Spp.) On Native Reef Fish Assemblages In Honduras, Lauren Henly

The Plymouth Student Scientist

The invasion of the Indo-Pacific lionfish (Pterois volitans and P. miles) to western Atlantic and Caribbean coral reefs has been documented as one of the most rapid and damaging marine finfish invasions to date, demonstrating strong negative impacts on native coral reef fish species. Comparatively little is known, however, about the effects of lionfish on whole reef fish assemblages and whether culling programmes actually make a difference reflected in fish assemblage measures. Data on reef fish assemblage metrics and community composition were collected using a diver-operated stereo-video system, in two locations with differing lionfish abundances in Honduras: Utila, where lionfish …

To What Extent Are Veterinary Practices Prepared To Treat Wildlife Patients? A Cross-Sectional Study Of Perceptions Of Responsibility And Capability Of Treating Wildlife In Uk Veterinary Practices, Emily Barnes

The Plymouth Student Scientist

Attribution of responsibility for wildlife is ambiguous, which can be problematic for those inextricably associated with wildlife care and managing decision-making processes, including veterinary professionals within general practice. Large numbers of wildlife casualties are frequently presented to veterinary practices. But there are few published data detailing this demand, the ability to respond to this demand, the attitudes towards this role and any benefits or disadvantages associated. This paper adopts a cross-sectional design involving a semiquantitative online questionnaire to develop understanding of the interface between veterinary practices and wildlife casualty management. The questionnaire was distributed to 1,706 veterinary practices in the …

Thermal Consolidation Of Dredge Sand For Artificial Reef Formations, Alexandro Trevino

Theses and Dissertations

Coral Reef ecosystems have degraded over years due to a variety of environmental issues such as ocean acidification. The continuous stress has detrimental effects on coral reef ecosystems that can possibly lead to the loss of the ecosystem. Our research aims to construct a prototype of an artificial reef by consolidating dredge sand from the ship channels of South Texas. Consolidation is achieved through an aluminum polytetrafluoroethylene self-propagating high temperature process that yields a solid formation to mimic the physical properties of coral reef structures. Using thermodynamic calculations, the variation of initial components was determined that reached an adiabatic temperature …

Oxidative Insults Disrupt Mitochondrial Dynamics, Iraselia A. Garcia

Theses and Dissertations

Mitochondria form an organellar network to provide ATP to the cell. Mitochondrial DNA (mtDNA) combines with nuclear DNA to encode polypeptides critical to forming the complexes of oxidative phosphorylation in the mitochondrial inner membrane, which generate a transmembrane potential (ΔΨm) to synthesize ATP. This ΔΨm is required to maintain mitochondria fission/fusion dynamics: organellar fusion (mediated by OPA1) and fission events (mediated by DRP1) coordinately regulate mitochondrial dynamics. While oxidative stress correlates with mitochondrial dysfunction, it is unclear how oxidants affect mitochondrial structure/function homeostasis. This project seeks to establish and examine the impact of reactive oxygen species (ROS) on mitochondrial dynamics. …

Removal Of Lead And Arsenic From Aqueous Solution By Biochar Produced From Locally-Sourced Biomass, Sergio I. Mireles

Theses and Dissertations

This study evaluated the effectiveness of four adsorbent materials, pyrolyzed corn stover, orange peel, pistachio shell, and magnetic biochar for their ability to adsorb lead (Pb) and arsenic (As III, As V) from aqueous solution. An increase in adsorption was seen as the pH of the solution increased from pH 2 to pH 6. Magnetic orange peel biochar with Fe3O4 particles precipitated on the surface of biochar was synthetized by co-precipitation and used for arsenic adsorption. Initial pH value had an influence on the adsorption behavior of As (III) and As (V). In the pH range of 2–6, As (V) …

The Effect Of "Casitas" On Lobster Biology And Fishery Sustainability In The Bahamas, Lester George Gittens

Biological Sciences Theses & Dissertations

“Casitas” (artificial table-like structures) are a commercial fishing gear used to harvest Caribbean spiny lobster (Panulirus argus) in the Caribbean and in The Bahamas, where lobster is the most valuable fishery. Yet, casitas are largely unregulated in The Bahamas and they may threaten fishery sustainability through alteration of lobster growth, disease, or mortality rates and due to insufficient information concerning their number and location. Focusing on the lobster fishery in The Bahamas, my objectives were to: (1) investigate the mortality, growth, and susceptibility to disease of lobsters collected in casitas compared to wooden traps and those living in …

Metabolite Profiling Of Infection-Associated Metabolic Markers Of Onchocerciasis., Sasisekhar Bennuru, Sara Lustigman, David Abraham, Thomas B. Nutman

Department of Microbiology and Immunology Faculty Papers

The global efforts for onchocerciasis elimination may require additional tools (safe micro and macrofilaricidal drugs, vaccines and biomarkers) as elimination efforts move toward the "end game". Efforts toward the identification of suitable biomarkers have focused on specific protein(s) and/or nucleic acids, but metabolites present an alternative option as they have limited half-lives and are the result of combinatorial effects. In comparison to previously used methodology of LC-MS for metabolomic approaches, we used a non-targeted capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS) to analyze the serum metabolic profiles of Ov-infected and -uninfected individuals (n=20). We identified 286 known metabolites (167 in the …

Acute Presentation Of Congenital Diaphragmatic Hernia Requiring Damage Control Laparotomy In An Adult Patient, S He, Irony Sade, Gary Lombardo, Kartik Prabhakaran

NYMC Faculty Publications

Congenital diaphragmatic hernias constitute an infrequent but potentially serious presentation of bowel obstruction in the adult patient. Herein, we present a rare case of an adult patient with strangulation of colon within a Morgagni's hernia where timely recognition and intervention were life-saving. An 18-year-old female presented with an acute abdomen, respiratory failure, and shock secondary to a strangulated, previously undiagnosed Morgagni hernia requiring emergency laparotomy, reduction of hernia contents and resection of non-viable colon. The patient underwent repair of the hernia with restoration of bowel continuity and reconstruction of her abdominal wall in sequential fashion. Although congenital diaphragmatic hernias have …

Characterization Of 3-Ester And 3-Carbamate Derivatives Of N-Acetyl-D-Glucosamine And Their Use In Controlled Drug Delivery, Consuelo Garcia

Chemistry & Biochemistry Theses & Dissertations

Low molecular weight gelators (LMWGs) are a class of compounds which reversibly form a network that traps solvents to form gels. Gelation by LMWGs is driven solely by non-covalent interactions such as hydrogen bonding, π - π stacking, and hydrophobic interactions. LMWGs can be designed such that the gel-sol and sol-gel transitions happen as a response to a specific stimulus. These stimulus responsive gels or “smart” gels can be used in a wide variety of applications including tissue regeneration, biosensing, and controlled drug delivery.

Among the different types of compounds that are LMWGs, carbohydrate based systems are especially interesting. Carbohydrates …

A Comparative Study Of The Effects Of External Selection On Settleability And Formation Of Aerobic Granular Sludge, Tyler A. Brickles

Civil & Environmental Engineering Theses & Dissertations

Aerobic granular sludge (AGS) has shown much promise in the advancement of the wastewater treatment industry. AGS has been studied intensely since the early 1990’s due to highly desirable characteristics of nutrient removal efficiency, low footprint, and abnormally faster settling rates than conventional activated sludge. With the exception of a few on-going research projects, all AGS systems have been studied and implemented through the use of sequencing batch reactors (SBR). Recently, a novel approach to developing AGS and improving settling characteristics of activated sludge within conventional activated sludge (CAS) processes has being attempted through the use of external selection.

Rediscovery Of The Microtubule System In Chlamydomonas, Yi Liu

Dissertations (1934 -)

Extensive studies have revealed the complex mechanisms underlying the roles of the microtubule system in fundamental cellular processes, the severe consequences in development and health resulted from its anomaly, and the irreplaceable therapeutic agents that perturbs this vital yet inherently unstable cytoskeletal system. Most of the concepts derived from a handful of model organisms become dogma of the field despite contrary observations. By overcoming a major limitation of biflagellate green alga Chlamydomonas - the intense autofluorescence common to photosynthetic cells - this dissertation discovered new phenomena of the microtubule system and conceived an invention. The microtubule system of the green …
