Developmental Ethanol Exposure Causes Central Nervous System Dysfunction And May Slow The Aging Process In A Drosophila Model Of Fetal Alcohol Spectrum Disorder, Khaoula Belhorma, Nahed Darwish, Elizabeth Benn-Hirsch, Annalisa Duenas, Hillary Gates, Navneet Sanghera, Jodie Wu, Rachael L. French

Faculty Research, Scholarly, and Creative Activity

Alcohol is a known teratogen, and developmental exposure to ethanol results in fetal alcohol spectrum disorder (FASD). Children born with FASD can exhibit a range of symptoms including low birth weight, microcephaly, and neurobehavioral problems. Treatment of patients with FASD is estimated to cost 4 billion dollars per year in the United States alone, and 2 million dollars per affected individual's lifetime. We have established Drosophila melanogaster as a model organism for the study of FASD. Here we report that mutations in Dementin (Dmtn), the Drosophila ortholog of the Alzheimer's disease-associated protein TMCC2, convey sensitivity to developmental ethanol exposure, …

Detection Of Antibiotic Resistance Genes In The Wastewater Microbial Metagenome, Alan Caparaz Le Jun 2021

Detection Of Antibiotic Resistance Genes In The Wastewater Microbial Metagenome, Alan Caparaz Le

Master's Projects

The existential threat of emerging antibiotic resistance in microbial communities poses significant risks to public health. In particular, wastewater can serve as a point of confluence for pharmaceuticals and antibiotic-resistant bacteria from urban and agricultural settings. While this is a prime environment for genetic drift and horizontal transfer of antibiotic resistance genes (ARGs) and mobile genetic elements, it also presents an opportunity for resistome monitoring via shotgun metagenomic sequencing and downstream analysis. This project reports the application of a hybrid assembly approach for the detection of ARGs within DNA derived from a wastewater sample collected from the San José-Santa Clara …


Transcriptional Profiling Of Neurological Development Of Drosophila Following Bisphenol A Exposure, Eden Johnson Jun 2021

Transcriptional Profiling Of Neurological Development Of Drosophila Following Bisphenol A Exposure, Eden Johnson

Master's Projects

The ubiquitous environmental chemical bisphenol A (BPA) is an emerging risk factor for neurodevelopmental disorders (NDDs). BPA is an endocrine-disrupting chemical (EDC) that is thought to interfere with neuron development by changing neuronal gene expression. Impacting neurodevelopment in this manner can cause lasting changes in behavior and potentially lead to the development of NDDs. Delineating the molecular processes that incur changes in gene expression following BPA exposure will advance our understanding of how BPA impacts neurodevelopmental pathways and affects the pathophysiology of NDDs. An RNA-Sequencing (RNA-Seq) analysis pipeline was created for transcriptional profiling of neurological development in wild-type Drosophila melanogaster …

Footprints Of Fixed-Gear Fisheries In Relation To Rising Whale Entanglements On The U.S. West Coast, Blake E. Feist, Jameal F. Samhouri, Karin A. Forney, Lauren E. Saez

Faculty Research, Scholarly, and Creative Activity

On the U.S. West Coast, reports of whales entangled in fishing gear increased dramatically in 2014. In this study, a time series of fishing activity maps was developed from 2009 to 2016 for the four fixed-gear fisheries most commonly implicated in entanglements. Maps were generated using vessel monitoring system (VMS) data linked to port-level landings databases, which were related to entangled whale reports over the same time period and with modelled distributions of humpback whales Megaptera novaeangliae Borowski. Over the full study period, neither marked increases in fishing activity nor changes in fisheries footprints within regions with high whale densities …

Faculty Research, Scholarly, and Creative Activity

Understanding encounters between marine predators and fisheries across national borders and outside national jurisdictions offers new perspectives on unwanted interactions to inform ocean management and predator conservation. Although seabird–fisheries overlap has been documented at many scales, remote identification of vessel encounters has lagged because vessel movement data often are lacking. Here, we reveal albatrosses–fisheries associations throughout the North Pacific Ocean. We identified commercial fishing operations using Global Fishing Watch data and algorithms to detect fishing vessels. We compiled GPS tracks of adult black-footed Phoebastria nigripes and Laysan Phoebastria immutabilis albatrosses, and juvenile short-tailed albatrosses Phoebastria albatrus. We quantified albatrosses-vessel encounters …

Heart Rate And Startle Responses In Diving, Captive Harbour Porpoises (Phocoena Phocoena) Exposed To Transient Noise And Sonar, Siri L. Elmegaard, Birgitte I. Mcdonald, Jonas Teilmann, Peter T. Madsen

Faculty Research, Scholarly, and Creative Activity

Anthropogenic noise can alter marine mammal behaviour and physiology, but little is known about cetacean cardiovascular responses to exposures, despite evidence that acoustic stressors, such as naval sonars, may lead to decompression sickness. Here, we measured heart rate and movements of two trained harbour porpoises during controlled exposure to 6–9 kHz sonar-like sweeps and 40 kHz peak-frequency noise pulses, designed to evoke acoustic startle responses. The porpoises initially responded to the sonar sweep with intensified bradycardia despite unaltered behaviour/ movement, but habituated rapidly to the stimuli. In contrast, 40 kHz noise pulses consistently evoked rapid muscle flinches (indicative of startles), …

Library Philosophy and Practice (e-journal)

The retrieval of superior-quality photographs with a minimal exposure is an interesting subject in radiography. Pre-processing is a key phase in signal and image processing such as healthcare, telecommunications, and satellite, and it focuses on reducing or eliminating the extent of noise in the image. Denoising aids in the recovery of finer data and relevant material. Medical images including ECG, Ultrasound, CT-scan, and X-ray provide incredibly fine data that has to be precise and noise-free in order for the knowledge and aspects of interest to be retained during diagnosis. Various noise reduction technologies for medical images, such as wavelet transform, …
