Analysis Of Symptom Expressions And Transmission Rates Caused By The Plant Pathogen Phytophthora Ramorum On Native Chaparral Plants From The Genus Arctostaphylos, Bharati Gaonker May 2021

Analysis Of Symptom Expressions And Transmission Rates Caused By The Plant Pathogen Phytophthora Ramorum On Native Chaparral Plants From The Genus Arctostaphylos, Bharati Gaonker

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Phytophthora ramorum is the causal agent of Sudden Oak death (SOD), ramorum dieback and ramorum leaf blight which affect both forest environments and nurseries. This oomycete pathogen has had a huge economic impact on the nursery and lumber industry. Forests in California have experienced substantial mortality of oaks affecting the forest dynamics and diversity. Our research investigates four native species and two ornamental cultivars of plants, which belong to the genus Arctostaphylos (manzanita) and are considered to be new hosts for P. ramorum in the chaparral ecosystem of California. Symptom expression and transmission rates were analyzed on Arctostaphylos glauca, …


Best Practices In A Clinical Development Project Management Office (Pmo) To Achieve A Reference Standard In The Pharmaceutical Industry, Russell Guinto Aug 2018

Best Practices In A Clinical Development Project Management Office (Pmo) To Achieve A Reference Standard In The Pharmaceutical Industry, Russell Guinto

Dissertations, Masters Theses, Capstones, and Culminating Projects

Medications are developed by the pharmaceutical industry starting with the discovery phase, proceeds to preclinical trials, moves into clinical trials (progressing from Phase I to Phase III), and if the data are positive, may lead to Food and Drug Administration (FDA) approval. Once approved, post-marketing surveillance for safety is required as long as the drug is marketed to consumers. This phase may also include clinical trial Phase IV studies if additional safety testing is required. This process usually takes between ten to fifteen years, with clinical development taking seven to ten years of that time (1). Clinical development can …


Mammalian Cell Line Development Platform For Recombinant Protein Production: Expanding The Protein Expression Toolbox For Research And Drug Discovery Applications, Elizabeth Del Greco May 2017

Mammalian Cell Line Development Platform For Recombinant Protein Production: Expanding The Protein Expression Toolbox For Research And Drug Discovery Applications, Elizabeth Del Greco

Dissertations, Masters Theses, Capstones, and Culminating Projects

Recombinant proteins have revolutionized the biomedical industry, providing therapeutics for life-threatening diseases and protein reagents for research applications. BioMarin Pharmaceutical Inc. develops recombinant protein therapeutics to treat rare diseases including lysosomal storage disorders (LSDs), a group of about 50 individually rare disorders together affecting 1 in 8,000 live births. With an increase in the number of novel therapeutics in our drug discovery pipeline, there is a high demand to produce a variety of recombinant proteins for early-stage drug development projects. In order to equip our protein production process with the tools and capability for diverse protein expression, it is valuable …


Stem Cell Derived Osteoprogenitors And Their Role In Bone Repair Using Morphogenic Activators, George Washington Brownridge Iii, Sylvanna Islas, Angelina Miller, Warren Hoeffler Apr 2017

Bone constantly cycles through a dynamic process of breakdown and remodeling. Osteoblasts are the specialized mesenchymal stem cells that have a major role in bone formation and the remodeling process whereas their counterpart osteoclasts, handle bone resorption. Embryonic stem cells can be partially differentiated into Progenitor cells, and we worked with #18, a candidate for being an osteoprogenitor that has the potential to respond to morphogenic activators. In the case of bone remodeling, TGF-β 2, BMP-2 and an abundance of CA++ have been shown to be potential activators of differentiation into osteoblasts. Eight different trials were conducted with the cells …


Development Of Quantitative Tools For The Characterization And Analysis Of The Blood Brain Barrier In Normal And Mps Iiib Mice, Sara M. Rigney May 2015

Development Of Quantitative Tools For The Characterization And Analysis Of The Blood Brain Barrier In Normal And Mps Iiib Mice, Sara M. Rigney

The Blood Brain Barrier (BBB) functions to control homeostasis within the central nervous system (CNS) via strict control over the passage of molecules into and out of the brain. The goal of this barrier is to protect the CNS from harmful external factors while allowing entry of essential nutrients and removal of metabolic byproducts. This restrictive nature of the BBB is due to the protein network at the borders of adjoining cerebral endothelial cells known as the tight junctions (TJs) and the relationship of other supporting cells and proteins such as astrocytes, pericytes, microglia, and the basement membrane and extracellular …


Potential Role Of Micro-Algae On Global Energy Supply, Sage Callaway-Keeley, Stephanie Huynh Apr 2009

Potential Role Of Micro-Algae On Global Energy Supply, Sage Callaway-Keeley, Stephanie Huynh

Student Research Posters

The most effective ways to reduce CO2 emissions are to improve the energy efficiency of each economic sector and to reduce the cutting of tropical and temperate forests around the world. These options, however, may not fully reach their technical and economic potential due to various political and socioeconomic. The most practical of these is to increase CO2 sinks through photosynthesis in both standing tree biomass and in ocean primary producers. The use of marine algae as CO2 sinks is for large-scale CO2 mitigation: the use of phytoplankton through Fe fertilization and macro algal (kelp) farms, which can be used …

The global energy economy is huge and thoughts of replacing large amounts of petroleum based fuels by massive levels of fermentation of grains are not realistic. On an energy basis what global agriculture produces for food will almost cover the energy demands if all of it is redirected to the production of fuels—either as alcohols for gasoline or as fat derivatives for diesel fuel. This means that chemical processes need to be developed that allow inclusion of non-food based agricultural and urban wastes as well as forest debris into the energy economy. These represent opportunities to capture new sources of …
