The Effects Of Different Cryopreservation Techniques On The Survival Rate Of In Vitro Produced (Ivp) And Biopsied Bovine Blastocysts, Diana J. Gumber

Animal Science

This study’s objectives were to determine if the biopsy of expanded blastocysts prior to cryopreservation affected the survival rates and determine if there is a difference between slow-freezing in 10% glycerol, slow freezing in ethylene glycol, and vitrification in terms of survival rate of the embryos. Blastocoeles were reduced prior to cryopreservation by means of biopsy. Embryos for slow freezing were exposed to ethylene glycol (SynGRO Ethylene Glycol with Sucrose, BIONICHE, Pullman, WA, USA) or 10% glycerol (SynGRO 10% Glycerol, BIONICHE, Pullman, WA, USA) as cryoprotectants. Vitrified embryos were exposed to 10% and 40% ethylene glycol. Survival rate of biopsied …

Investigation Of Chromosome Size Effect On The Rate Of Crossovers In The Meiotic Yeast Saccharomyces Cerevisiae, Lanie Maria Galland

Master's Theses

Meiosis is a specialized type of cell division characterized by a single round of DNA replication and two rounds of chromosome segregation, ultimately resulting in four haploid cells. During meiosis I, chromosomes align and reciprocal recombination results in the formation of a crossover, creating the tension required to properly segregate homologs during the first round of meiosis.

Two mechanisms involved in regulating the occurrence of crossing over are assurance and interference. Crossover assurance describes the phenomenon that at least one crossover will form between each pair of homologous chromosomes during prophase I. Crossover interference, on the other hand, describes the …

Development And Implementation Of Assessment Methods For Tissue-Engineered Blood Vessel Mimics, Tanner Stevenson

Biomedical Engineering

Coronary Artery Disease (CAD), the most prevalent form of heart disease, is the result of clogged or damaged coronary arteries and claims around 380,000 Americans annually. A common treatment for CAD involves placing a stent into the artery in order to open the lumen and support the native tissue—a procedure that drastically reduces patient recovery times in comparison to heart bypass surgery. However, stents do not always interact well with the body and require additions such as surface coatings or drug elution in order for additional biocompatibility. These additions necessitate extensive in vitro and in vivo testing which are expensive …

Endothelial And Smooth Muscle-Dependent Vascular Reactivity In Immature Arterialized Collateral Capillaries, Caitlin Koeroghlian

Biomedical Engineering

Peripheral arterial occlusive disease (PAOD) occurs due to the build up of atherosclerotic plaque and reduces blood flow to cause chronic ischemia. Patients with PAOD may experience intermittent claudication, or the pain in limb skeletal muscles due to a decease in blood flow. Collateral arteries can act as a natural bypass and improve blood flow to hypoxic tissue by creating an alternate route for blood to flow, but not all patients with PAOD have pre-existing collateral networks. Animal studies indicate that tissues without pre-existing collateral networks can form de novo collaterals from capillaries following occlusion of a feed artery. Unfortunately, …

Play From The Heart: On Crafting A Community Of Empathy In The Theatre, Kevin Kingston

The Theatre School MFA in Directing Theses

The power of story goes beyond mere escapist entertainment. Yes it should entertain, but that is not the ultimate goal. It may even offer a bit of escape, but again this is not the holy grail. When we experience a well-crafted narrative, we are called to cross a threshold. We pass through the door of our own life and enter into the experience of another. This is what we mean when we say we "got lost" in the story. We take on the experience of another as our own. When a group of people experience a narrative they cross this …

Applications and Applied Mathematics: An International Journal (AAM)

The s teady flow of an incompressible couple stress fluid in a two dimensional uniform channel with stenosis under the influence of a magnetic field has been investigated. Assuming the stenosis to be mild, the flow equations have been analy tically solved using the slip condition and expressions for the resistance to flow and wall shear stress have been derived. The effects of various parameters on these flow variables have been studied. It is found that the resistance to flow as well as the wall shear stress increase with the height of the stenosis and decrease with the couple stress …

Modeling The Transmission Dynamics Of Typhoid In Malaria Endemic Settings, Steady Mushayabasa, Claver P. Bhunu, Ngoni A. Mhlanga

Applications and Applied Mathematics: An International Journal (AAM)

Typhoid and malaria co-infection is a major public health problem in many developing countries. In this paper, a deterministic model for malaria and typhoid co-infection is proposed and analyzed. It has been established that the model exhibits a backward bifurcation phenomenon. Overall, the study reveals that a typhoid outbreak in malaria endemic settings may lead to higher cumulative cases of dually-infected individuals displaying clinical symptoms of both infections than singly-infected individuals displaying clinical symptoms of either malaria or typhoid.

Effect Of Toxic Metal On Root And Shoot Biomass Of A Plant A Mathematical Model, O. P. Misra, Preety Kalra

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, a mathematical model is proposed to study the impact of toxic metals on plant growth dynamics due to transfer of the toxic metal in plant tissues. In the model, it is assumed that the plant uptakes the metal from the soil through the roots and then it is transfered in the plant tissues and cells by transport mechanisms. It is observed experimently that when toxic (heavy) metals combines with the nutrient they form a complex compound due to which nutrient loses its inherent properties and the natural charaterstics of the nutrient are damaged. It is noticed that …

Dynamics Of Phytoplankton, Zooplankton And Fishery Resource Model, B. Dubey, Atasi Patra, R. K. Upadhyay

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, a new mathematical model has been proposed and analyzed to study the interaction of phytoplankton- zooplankton-fish population in an aquatic environment with Holloing’s types II, III and IV functional responses. It is assumed that the growth rate of phytoplankton depends upon the constant level of nutrient and the fish population is harvested according to CPUE (catch per unit effort) hypothesis. Biological and bionomical equilibrium of the system has been investigated. Using Pontryagin’s Maximum Principal, the optimal harvesting policy is discussed. Chaotic nature and bifurcation analysis of the model system for a control parameter have been observed through …

The Future Of Weapons Of Mass Destruction: Their Nature And Role In 2030, John P. Caves Jr., W. Seth Carus

WMD Occasional Papers

The longstanding efforts of the international community writ large to exclude weapons of mass destruction (WMD) from international competition and conflict could be undermined in 2030. The proliferation of these weapons is likely to be harder to prevent and thus potentially more prevalent. Nuclear weapons are likely to play a more significant role in the international security environment, and current constraints on the proliferation and use of chemical and biological weapons could diminish. There will be greater scope for WMD terrorism, though it is not possible to predict the frequency or severity of any future employment of WMD. New forms …

Combining Familial Searching And Abandoned Dna: Potential Privacy Outcomes And The Future Of Canada's National Dna Data Bank, Amy Conroy

Canadian Journal of Law and Technology

This article aims to respond to the government’s request by explaining the nature of that relationship and by arguing that the combined use of familial searching and analysis of abandoned DNA would present a serious risk for genetic privacy. The risk is particularly acute given that it would effectively circumvent the existing justification for the NDDB, leading to inclusion of individuals whose DNA profiles have not been uploaded directly onto the data bank. To substantiate this main argument, this article proceeds in three parts. The first describes the current Canadian law on familial searching and the ongoing interest in amending …

Understanding the mechanism of OA development in the TMJ helps in understanding how OA progresses and how to treat this disease. The goal of this investigation is to examine the process of cartilage degeneration and OA biomarker expression in the TMJ to understand their role in TMJ OA onset and development.Chapter one covers mechanisms that are altered in TMJ OA during disease progression. Using animal models with different stressors such as mechanical disturbances, direct injury, and …

Rapid Adaptation Of Dopamine D2 Receptor Responses In The Brain And Blood Following Acute Ethanol, Ryan J. Folsom

Theses and Dissertations

Dopamine (DA) D2 receptor expression parallels DA levels in the brain and these autoreceptors have been shown to be modulated by long-term ethanol exposure. We have previously demonstrated that ventral tegmental area (VTA) GABA neurons also express D2 autoreceptors (D2R), and that DA and D2R agonists markedly enhance the excitability of VTA GABA neurons, opposite to their well-known auto-receptor inhibition of DA neurons. Most importantly, D2R antagonists block ethanol inhibition of VTA GABA neurons and D2R expression in VTA GABA neurons down-regulates with chronic ethanol, as others have shown for whole VTA D2R expression. The aim of this study was …

Examination Of Anabolic Signaling And Muscle Growth With Caffeine Treatment In Overloaded Hindlimb Muscle And Electrically Stimulated Muscle Lacking Liver Kinase B1, Timothy Michael Moore

Theses and Dissertations

Skeletal muscle has the ability to increase in size (hypertrophy) after resistance is placed upon it. This hypertrophy is marked by significant upregulation of the mammalian target of rapamycin (mTOR) and its downstream targets. The upstream kinases, protein kinase B (also known as Akt) and AMP-activated protein kinase (AMPK), are two of the many regulators of the mTOR pathway. Recent studies suggest that the widely consumed neuroactive compound caffeine could potentially inhibit mTOR by acting through Akt and/or AMPK. The purpose of this thesis was to: 1) determine if caffeine can inhibit the mTOR pathway and ultimately attenuate skeletal muscle …

Discovery Of Novel Serum Biomarkers For Diagnosing And Staging Alzheimer's Disease, Dipti Jigar Shah

Theses and Dissertations

Discovery of Novel Serum Biomarkers for Diagnosing and Staging Alzheimer’s DiseaseDipti Jigar ShahDepartment of Chemistry and Biochemistry, BYUDoctor of PhilosophyAlzheimer’s disease (AD) is an untreatable neurologic disease affecting more than 5 million Americans, most over 60 years of age. Protein plaques and neurofibrillary tangles typify AD brain pathology and are thought to cause the progressive dementia and brain shrinkage observed in AD. Currently there are no methods to diagnose the disease at a time before damage becomes irreversible.Biochemical tests for AD using cerebrospinal fluid analysis or neuroimaging are not yet sufficiently sensitive and specific, and they are invasive. This points …
