Studying Cellular And Molecular Interaction With Two-Photon Fluorescence Microscopy, Arifur Rahaman
Studying Cellular And Molecular Interaction With Two-Photon Fluorescence Microscopy, Arifur Rahaman
Open Access Theses & Dissertations
Advances in microscopy and fluorescent probes provide new insight into studying cellular and molecular interactions. Two-photon fluorescence microscopy is one of the most important recent inventions in cellular and molecular study. This technology enables noninvasive study at cellular and molecular levels in three dimensions with submicrometer resolution. Two-photon excitation of fluorophores results from the simultaneous absorption of two photons. This excitation process has a number of unique advantages, such as reduced specimen photodamage and enhanced penetration depth. In this study, we used our two-photon microscope to observe predatorial behavior of fast moving bacterivorous marine organism Cafeteria roenbergensis and quantify Mycobacterium …
Evaluation Of Small Molecules On The Excitatory Amino Acid Transporter 3 (Eaat3) For The Treatment Of Ocd, Emmanuel Zubia
Evaluation Of Small Molecules On The Excitatory Amino Acid Transporter 3 (Eaat3) For The Treatment Of Ocd, Emmanuel Zubia
Open Access Theses & Dissertations
We seek to discover new drug candidates for the excitatory amino acid transporter 3 (EAAT3) for the treatment of Obsessive Compulsive Disorder (OCD). We hypothesize that decreasing the glutamatergic transmission via EAAT3 intervention will create an amelioration of the symptoms of OCD. For this we have prepared in-silico binding calculations to identify a better compound that can stimulate EAAT3 and decrease glutamatergic transmission. This research will help us further understand and elucidate the role of glutamate in the neural mechanisms of this illness, which to date remain inconclusive. Those areas of study are significant because, until now, there is no …
Role Of Small Molecules In Rescuing Protein Folding Under Oxidative Stress, Mahmoud Fawzi Megahed Helal Khalil
Role Of Small Molecules In Rescuing Protein Folding Under Oxidative Stress, Mahmoud Fawzi Megahed Helal Khalil
Open Access Theses & Dissertations
Increased levels of nitrosative stress intracellularly within the endoplasmic reticulum is a key factor involvled in the pathogenesis of both Parkinson's (PD) and Alzheimer's (AD) diseases. Previous in-vitro studies in our lab showed that increased levels of nitrosative stress lead to aggregation of misfolded proteins and formation of Lewy Bodies, the main biomarker of PD and AD diseases. Although this was mainly through nitrosylation of Protein Disulfide Isomerase (PDI), the chief endoplasmic reticulum (ER) resident oxidoreductase chaperone responsible for maturation of disulfide-bond-containing proteins, we demonstrate in this project that increased levels of nitrosative stress has an additional direct effect on …
Exploratory Study Of Seasonal Indoor Bioaerosols And The Associated Health Outcomes In Low-Income Communities In El Paso, Texas, 2014, Eric Martinez
Exploratory Study Of Seasonal Indoor Bioaerosols And The Associated Health Outcomes In Low-Income Communities In El Paso, Texas, 2014, Eric Martinez
Open Access Theses & Dissertations
Introduction: Structural degradation, moisture levels, and building failures can influence poor indoor air quality and create a good environment for bioaerosols. People spend much of their time indoors and can potentially be exposed to these bioaerosols. Several studies have correlated exposures to high concentrations of bioaerosols to various health problems, severe allergies, asthma, or other respiratory illness. Objectives: The objectives of this study are to describe bioaerosol concentrations, meteorological factors, and health outcomes during the summer and fall seasons; characterize bioaerosols (bacteria and fungi) collected in low-income communities; compare bioaerosol concentrations by season; compare meteorological factors to bioaerosol concentrations by …
An Assessment Of The Role Of Roads In Population Demography And Genetic Structuring In Two Species Of Lizards In The Northern Chihuahuan Desert, Kevin Floyd
Open Access Theses & Dissertations
Roads can fragment habitat and increase mortality rates of wildlife, potentially reducing population sizes and gene flow, which in turn can reduce genetic diversity through genetic drift. Although negative road impacts have been found in a variety of taxa, not all species are impacted. For instance, species that move less and rarely encounter roads and those that avoid the roads are predicted to not be negatively affected. Yet tests of these predictions are uncommon, especially for reptiles and particularly lizards. Side-blotched lizards (Uta stansburiana) are small sit-and-wait predators, while the larger marbled whiptails (Aspidoscelis marmorata) are active foragers. Their responses …
The Impacts Of Water Availability On Macroinvertebrate, Ector Matias Martell
The Impacts Of Water Availability On Macroinvertebrate, Ector Matias Martell
Open Access Theses & Dissertations
In many regions around the world climate is changing and biotic communities are changing with it. In areas like the southwestern U.S., drought is one of the major sources of disturbance. Although droughts are an integral part of the natural hydrological cycles, they can have devastating effects on freshwater ecosystems when disrupted by extended periods of drought, resulting in changes to the structure and function of biotic communities. In this study, we surveyed four streams in the Sacramento Mountains of New Mexico from 2010 to 2014: Agua Chiquita, Rio Peñasco, Wills Creek, and the Sacramento River; These years encompassed an …
Nanoceria Exposure To Kidney Beans (Phaseolus Vulgaris): Implications On Plant Physiology, Nutrition And Their Transfer To Next Trophic Level, Sanghamitra Majumdar
Nanoceria Exposure To Kidney Beans (Phaseolus Vulgaris): Implications On Plant Physiology, Nutrition And Their Transfer To Next Trophic Level, Sanghamitra Majumdar
Open Access Theses & Dissertations
Previous studies investigating the effects of cerium oxide nanoparticles (nanoceria, nCeO2) on plants have primarily focused on the physiological and biochemical changes at early growth stages. Comprehensive information on the effects of nCeO2 through the entire life cycle of plants and the nutritional quality of the edible tissues is limited. No studies have been reported on the interactions between nCeO2 and common beans (Phaseolus vulgaris). Common beans are leguminous crops, which are societally important due to their nutritional benefits. The beans are rich in proteins and essential nutrients like folate, iron, zinc, molybdenum and magnesium, and are consumed worldwide. This …
