Molecular Identification And Characterization Of Viral Pathogens Infecting Sweet Cherry, Aaron J. Simkovich

Electronic Thesis and Dissertation Repository

Stone fruits are a valuable crop grown worldwide, however pathogens such as viruses threaten fruit production by reducing tree health and fruit yield. In an orchard within the Niagara region of Ontario, symptoms typical of viral infection such as chlorosis and leaf deformation were seen on sweet cherry (Prunus avium L.) trees. Next generation sequencing was performed on symptomatic and asymptomatic leaves and four viruses were identified. On the tree displaying the most severe symptoms, Prune dwarf virus (PDV), was the only virus detected. A survey conducted during this work showed 42% of cherry trees on a single …

An Evaluation Of Challenges And Opportunities For Western Heads East [2017], Felicia Krausert, Reshel Perera,, Spencer Yeung, Jacinta Mwachiro, Bob Kigen, Elizabeth Pham

Business and Social Enterprise

Western Heads East (WHE) is “a collaboration between Western staff, students, faculty, and African partners using probiotic food to contribute to health and sustainable development”. The primary objective of this program is to establish a sustainable grassroots social enterprise using the health benefits of probiotic yoghurt in order to improve health of Tanzanian community while empowering local women to become business owners and entrepreneurs. This report investigates the challenges, opportunities, local conditions and previous works to recommend a potential intervention that could support the sustainability and the intended value of probiotic yoghurt kitchens.

There are two main end users for …

Development And Performance Evaluation Of An Antibody-Based Technology For Detection Of E. Coli O157 In Meat Samples And Its Potential Evolution Using Antibody Engineering, Yadira Tejeda Saldaña

Electronic Thesis and Dissertation Repository

Escherichia coli O157 is a persistent pathogen linked to food and waterborne infectious outbreaks with severe health consequences such as hemorrhagic colitis and hemolyticuremic syndrome (HUS). Because it is considered one of the major pathogens that contributes to the global burden of foodborne disease, its early detection within the food chain is an important milestone towards reducing foodborne diseases and economic losses due to contaminated food. Herein, the development and validation of a lateral flow immunoassay (LFIA) point-of-care (POC) device is described. Application of the LFIA test kit was focused on detection of E. coli O157 in raw meat products …

Hd2d Is A Regulator Of Abscisic Acid Responses In Arabidopsis, Joshua A. Farhi

Electronic Thesis and Dissertation Repository

Histone deacetylases have important roles in development and stress response in plants. To further investigate their function, the HD2D gene, of the plant specific HD2 family, was studied. An hd2d-1 mutant and two HD2D overexpression lines were used in this study. Germination was delayed in hd2d-1 and HD2D overexpression seeds only in the presence of ABA. HD2D was found to positively regulate the expression of members of the ABA-response pathway (ABI1, ABI5, and RD29A) leading to increased resistance to drought and salinity treatments. Furthermore, HD2D expression delayed flowering by positively regulating FLC expression. Using bimolecular fluorescence complementation, the HD2D protein …

Clinical And Mechanistic Insights Into Novel Probiotic Functions And Formulations, Jordan Bisanz

Electronic Thesis and Dissertation Repository

Using a combination of hypothesis and discovery based approaches, the goal of this thesis was to better describe novel probiotic functions and their mechanisms while striving to better understand the effect of formulation on Bifidobacterium animalis subsp. lactis, Lactobacillus paracasei and L. rhamnosus.

Using RNA-Seq, a bacterial metatranscriptome analysis of a commonly consumed probiotic yogurt showed that the organisms adapted to storage time and flavor additions. This led to the discovery that in addition to the probiotic health benefits, members of the L. casei group (L. rhamnosus and L. paracasei) produce volatile sulfur compounds mediated by a novel …

Establishing A Kitchen With Jkuat, Kenya [2015], Germaine Tuyisenge

Business and Social Enterprise

Internship Report 2015

From May to August,2015a group of four interns, from Western Universitywere in a placement at Jomo Kenyatta University of Agriculture and Technology(JKUAT), doing an internship with Western Heads East.The interns were working onFiti Projectfor the production of Probiotic Yoghurt. The team of interns was multidisciplinarywith the four students taking different programs at Western: Medical Sciences, finance, political sciences and health-geography. Thiswas an asset for the project,helpingto have a strong approach on how to make ita success, everyone bringing in her own expertise. Our overall goal for the projectwas toestablish a probiotic kitchen at JKUAT, and that kitchen …

Interesting Shapes Of Vegetables: Is It A Strategy To Promote Consumption Among Preschool Children?, Salma H. Alhabshi

Electronic Thesis and Dissertation Repository

This study highlighted the low intake of vegetables by preschool children and determined whether changing the shape of vegetables increased their level of consumption. A new strategy of repeated exposure to interesting-shaped vegetables was a step aimed at increasing vegetable consumption by increasing the fun element in having vegetables as snacks. Vegetables are the less desirable food in comparison to more attractive unhealthy choices available to children, and discovering a strategy to promote vegetables is considered an important step in nutrition. The primary aim was to explore the effect of repeated exposure (eight times) of shaped vegetables on consumption by …

Uncovering The Molecular Link Between Mir156.Spl15 And Carotenoid Accumulation In Arabidopsis, Davood Emami Meybodi

Electronic Thesis and Dissertation Repository

Carotenoid Cleavage Dioxygenases (CCDs) are an enzyme family that cleaves specific double bonds in carotenoids. MicroR156 in Arabidopsis regulates a network of genes by repressing 10 SPL genes, among which, SPL15 was found to regulate shoot branching and carotenoid accumulation. The expression of CCD1, CCD4, CCD7, CCD8, NCED2, NCED3, NCED5, NCED6, NCED9 and SPL15 was evaluated in siliques at 10 days post anthesis and in 10-day-old roots in Arabidopsis wild type, sk156 (miR156 overexpression mutant), RS105 (miR156 overexpression line), spl15 (SPL15 knockout mutant) and two 35S:SPL15 lines. Results showed that most of CCD/NCED genes were …

African Probiotic Yoghurt Network : Western Heads East Internship Report, Emily Trudell

Business and Social Enterprise

The purpose of this report is to explain to all stakeholders, and especially Western Heads East (WHE), the progression of my internship work with APYN alongside the progression of APYN’s establishment as an organization during the second half of my internship,to provide APYN with a recordof the activities we worked on together, and tohand over the documents APYN and I produced collaboratively to APYN to help guide future organizational decisions. I will begin with a review of my planning workshop, from which my two main activities stemmed, and then provide descriptions and analysis surrounding each one in the body of …

Photocalytic Degradation Of Malic Acid Under Thin Coated Tio2, Vanessa Silveira Rodgher

Electronic Thesis and Dissertation Repository

Opaque fluids have a limited irradiation transmission. Thus, their decontamination employing near UV irradiation poses significant technical challenges. In the present study, a thin UV-transparent/waterproof glue layer coated with a 1.5 wt% of TiO₂ and a new PhotoReactor Cell were implemented. TiO₂ irradiation in the PhotoReactor Cell was effected on the TiO₂ particle side, not directly in contact with the fluid, allowing the postulation of an “h⁺” site mobility mechanism on photocatalysis.

Photocatalytic degradation experiments with malic and malonic acid in water at 10, 20, 30 and 40 ppm showed the complete degradation of malic …
