Acoustic Energy Harvesting And Sensing Via Electrospun Pvdf Nanofiber Membrane, Nader Shehata, Ahmed H. Hassanin, Eman Elnabawy, Remya Nair, Sameer A. Bhat, Ishac Kandas May 2020

Acoustic Energy Harvesting And Sensing Via Electrospun Pvdf Nanofiber Membrane, Nader Shehata, Ahmed H. Hassanin, Eman Elnabawy, Remya Nair, Sameer A. Bhat, Ishac Kandas

Biology Faculty Publications

This paper introduces a new usage of piezoelectric poly (vinylidene fluoride) (PVDF) electrospun nanofiber (NF) membrane as a sensing unit for acoustic signals. In this work, an NF mat has been used as a transducer to convert acoustic signals into electric voltage outcomes. The detected voltage has been analyzed as a function of both frequency and amplitude of the excitation acoustic signal. Additionally, the detected AC signal can be retraced as a function of both frequency and amplitude with some wave distortion at relatively higher amplitudes and within a certain acoustic spectrum region. Meanwhile, the NFs have been characterized through …

Elucidating The Role Of The High Aliphatic Glucosinolate ( Hag ) Genes In Pennycress ( Thlaspi Arvense L. ) Glucosinolate Production, Dalton Williams May 2020

Elucidating The Role Of The High Aliphatic Glucosinolate ( Hag ) Genes In Pennycress ( Thlaspi Arvense L. ) Glucosinolate Production, Dalton Williams

Theses and Dissertations

Pennycress (Thlaspi arvense L.) is a Brassica species being developed into an oilseed-producing winter cash cover crop. Similar to its relatives, rapeseed (Brassica napus L.) and camelina (Camelina sativa L.), pennycress seeds produce high levels of oil and protein (~34% oil and ~19% protein dry weight). For pennycress to be economically viable and environmentally sustainable as a crop, both the oil and seed meal must be utilized. Pennycress like other Brassicaceae, produces high levels of glucosinolates in the seed coat. Glucosinolates taste bitter and can be metabolized by the enzyme, myrosinase, into toxic isothiocyanates, nitriles, and epithionitriles. Seed meal containing …

When mapped to the environments we interact with on a daily basis, the 36 million microbial cells per hour that humans emit leave a trail of evidence that can be leveraged for forensic analysis. We employed 16S rRNA amplicon sequencing to map unique microbial sequence variants between human skin and building surfaces in three experimental conditions: over time during controlled and uncontrolled incidental interactions with a door handle, and during multiple mock burglaries in ten real residences. We demonstrate that humans (n = 30) leave behind microbial signatures that can be used to track interaction with various surfaces within a …

The Abundant-Centre Is Not All That Abundant: A Comment To Osorio-Olvera Et Al. 2020, Tad Dallas, Samuel Pironon, Luca Santini May 2020

The Abundant-Centre Is Not All That Abundant: A Comment To Osorio-Olvera Et Al. 2020, Tad Dallas, Samuel Pironon, Luca Santini

Faculty Publications

Species abundance is expected to decrease from the centre towards the edge of their ecological niches (abundant niche-centre hypothesis). Recently, Osorio-Olvera et al. (2020) reported strong support for the abundant niche-centre relationship in North American birds. We demonstrate here that methodological decisions strongly affected perceived support. Avoiding these issues casts doubt on conclusions by Osorio-Olvera et al. and the putative support for the abundant nichecentre hypothesis in North American birds.

Biology Faculty Publications

Developmental plasticity generates phenotypic variation, but how it contributes to evolutionary change is unclear. Phenotypes of individuals in caste-based (eusocial) societies are particularly sensitive to developmental processes, and the evolutionary origins of eusociality may be rooted in developmental plasticity of ancestral forms. We used an integrative genomics approach to evaluate the relationships among developmental plasticity, molecular evolution, and social behavior in a bee species (Megalopta genalis) that expresses flexible sociality, and thus provides a window into the factors that may have been important at the evolutionary origins of eusociality. We find that differences in social behavior are derived …

School of Biological Sciences: Faculty Publications

Most proteins associate into multimeric complexes with specific architectures, which often have functional properties such as cooperative ligand binding or allosteric regulation. No detailed knowledge is available about how any multimer and its functions arose during evolution. Here we use ancestral protein reconstruction and biophysical assays to elucidate the origins of vertebrate hemoglobin, a heterotetramer of paralogous α- and β-subunits that mediates respiratory oxygen transport and exchange by cooperatively binding oxygen with moderate affinity. We show that modern hemoglobin evolved from an ancient monomer and characterize the historical “missing link” through which the modern tetramer evolved—a noncooperative homodimer with high …

Genome Skimming And Microsatellite Analysis Reveal Contrasting Patterns Of Genetic Diversity In A Rare Sandhill Endemic (Erysimum Teretifolium, Brassicaceae), José Carlos Del Valle, Julie A. Herman, Justen B. Whittall May 2020

Genome Skimming And Microsatellite Analysis Reveal Contrasting Patterns Of Genetic Diversity In A Rare Sandhill Endemic (Erysimum Teretifolium, Brassicaceae), José Carlos Del Valle, Julie A. Herman, Justen B. Whittall

Biology

Barriers between islands often inhibit gene flow creating patterns of isolation by distance. In island species, the majority of genetic diversity should be distributed among isolated populations. However, a self-incompatible mating system leads to higher genetic variation within populations and very little between-population subdivision. We examine these two contrasting predictions in Erysimum teretifolium, a rare self-incompatible plant endemic to island-like sandhill habitats in Santa Cruz County, California. We used genome skimming and nuclear microsatellites to assess the distribution of genetic diversity within and among eight of the 13 remaining populations. Phylogenetic analyses of the chloroplast genomes revealed a deep …

Flowering Plant Composition Shapes Pathogen Infection Intensity And Reproduction In Bumble Bee Colonies., Lynn S. Adler, Nicholas A. Barber, Olivia M. Biller, Rebecca E. Irwin May 2020

Flowering Plant Composition Shapes Pathogen Infection Intensity And Reproduction In Bumble Bee Colonies., Lynn S. Adler, Nicholas A. Barber, Olivia M. Biller, Rebecca E. Irwin

Department of Occupational Therapy Faculty Papers

Pathogens pose significant threats to pollinator health and food security. Pollinators can transmit diseases during foraging, but the consequences of plant species composition for infection is unknown. In agroecosystems, flowering strips or hedgerows are often used to augment pollinator habitat. We used canola as a focal crop in tents and manipulated flowering strip composition using plant species we had previously shown to result in higher or lower bee infection in short-term trials. We also manipulated initial colony infection to assess impacts on foraging behavior. Flowering strips using high-infection plant species nearly doubled bumble bee colony infection intensity compared to low-infection …

Effects Of Aurora Kinase C Expression On Retina Pigmented Epithelial Cell Migration, Proliferation, And Anchorage Independent Growth, Justin Bejar May 2020

Effects Of Aurora Kinase C Expression On Retina Pigmented Epithelial Cell Migration, Proliferation, And Anchorage Independent Growth, Justin Bejar

Seton Hall University Dissertations and Theses (ETDs)

Cancer is a common and deadly disease in the United States with 1,806,590 new cancer cases in 2019 and 606,520 cancer deaths projected in 2020. These deaths are primarily due to the uncontrolled cell proliferation and migratory nature of the disease. Many cancer cells express genes normally restricted to meiotic cells. For example, Aurora Kinase C (AURKC) is known to regulate chromosome segregation in meiotic cells yet it is expressed in many different types of cancer, such as breast, prostate, colorectal, liver, cervical, thyroid, and testicular cancers. As a means to study the function of AURKC, an …

Determining The Genetic Control Of Neural Tube Malformation Through Genetic Interactions With Idgf3, Elli N. Fox May 2020

Determining The Genetic Control Of Neural Tube Malformation Through Genetic Interactions With Idgf3, Elli N. Fox

Honors Projects

Genetic mutations disrupting human neural tube formation can lead to birth defects such as spina bifida and anencephaly. Defects can result in lack of neural tube closure in either the caudal (spina bifida) or cranial (anencephaly) regions. Little is known about the genes that cause these malformations. Researchers have been using the model organism Drosophila melanogaster in an attempt to determine genes responsible for neural tube malformations. Recently, an ortholog of human chitin-like protein, imaginal disc growth factor 3 (Idgf3), has been identified as important in the proper formation of Drosophila egg dorsal appendages. However, the molecular mechanism responsible for …

Lack Of Replication Disruption Following H2o2-Induced Damage In Escherichia Coli, Sierra S. Schmidt, Justin Courcelle, Charmain T. Courcelle May 2020

Lack Of Replication Disruption Following H2o2-Induced Damage In Escherichia Coli, Sierra S. Schmidt, Justin Courcelle, Charmain T. Courcelle

University Honors Theses

Hydrogen peroxide (H2O2) toxicity has long been thought to be predominantly due to oxidative DNA damage that can disrupt DNA replication and result in lethality. Curiously and contrary to this view, it is also well established that the glycosylases responsible for repairing oxidized-base damage are as resistant as wild-type cells when treated with H2O2. The observation raises the possibility that H2O2-induced DNA damage does not disrupt or prevent replication. To examine this possibility, I examined the sensitivity of recF mutants to H2O2. RecF is …

The Effect Of Intensified Illuminance And Artificial Light At Night On Fitness And Susceptibility To Abiotic And Biotic Stressors, Grascen Shidemantle May 2020

The Effect Of Intensified Illuminance And Artificial Light At Night On Fitness And Susceptibility To Abiotic And Biotic Stressors, Grascen Shidemantle

Biological Sciences Student Scholarship

Changing light conditions due to human activities represents an important emerging environmental concern. Although changes to natural light conditions can be independently detrimental, in nature, organisms commonly face multiple stressors. To understand the consequences of altered light conditions, we exposed a model amphibian (wood frog; Lithobates sylvaticus) to a control and two anthropogenic light conditions: intensified daytime illuminance and artificial light at night - ALAN (intensified daytime illuminance + extended photoperiod). We measured (1) metrics of fitness (hatching success as well as survival to, size at, and time to metamorphosis) (2) susceptibility (time to death) to a commonly cooccurring anthropogenic …

Characterizing The Function Of Lyases Involved In The Biosynthesis Of Phycoerythrin I And Ii From Marine Synechococcus Cyanobacteria, Lyndsay A. Carrigee

LSU New Orleans Theses and Dissertations

Marine Synechococcus are the second most abundant oxygenic phototrophs in the open ocean. They are efficient at harvesting available light using complex antenna, or phycobilisome, composed of allophycocyanin proteins and extended rod structures of phycocyanin and one or two types of phycoerythrin (PEI and PEII). This dissertation focuses on the enzymes called bilin lyases required for the biogenesis of PEI and PEII in marine strains of Synechococcus which undergo type 4 chromatic acclimation (CA4). I used interruption mutant analysis, high performance liquid chromatography, a protein expression system in E. coli, and liquid chromatography tandem mass spectrometry to characterize the …

Investigation Of Bax-Vdac Interactions And Their Role In Apoptosis, Marie Merrell May 2020

Investigation Of Bax-Vdac Interactions And Their Role In Apoptosis, Marie Merrell

Honors Theses

Apoptosis is the process of programmed cell death. Increasing knowledge of this biological process can lead to understanding of neurodegenerative diseases and cancer alike. In mammals, this process occurs through mechanisms that are localized to the mitochondria. The release of cytochrome c is from the mitochondrial outer membrane (MOM) is regulated by pro and anti-apoptotic Bcl-2 family proteins. If the latter are successful, then cytochrome c’s release into the cytosol activates a caspase cascade, resulting in apoptosis of the cell. Pro-apoptotic Bax is present in complexes that contain voltage dependent anion channels (VDACs). We hypothesized that in healthy cells, VDACs …

Developmental Programming Effects Of Maternal Obesity, Carolle J. Kassab May 2020

Developmental Programming Effects Of Maternal Obesity, Carolle J. Kassab

University Honors Theses

Population studies within the United States indicate increasing rates of obesity, considerably prominent for women within reproductive age. Maternal obesity is associated with the offspring’s hyperlipidemia, diabetes, and cardiovascular disease, which have chronic consequences. Obesity in pregnancy causes metabolic and epigenetic perturbations within the fetal environment, disrupting future health of offspring. This phenomenon is known as developmental programming. Although the relationship between maternal undernutrition and developmental programming has been demonstrated, its relationship to maternal obesity remains understudied.

Long Term Effects Of Concussions And The Frequency Of Injury To The Different Regions Of The Human Brain, Marissa S. Swadener May 2020

Long Term Effects Of Concussions And The Frequency Of Injury To The Different Regions Of The Human Brain, Marissa S. Swadener

University Honors Theses

Concussions, or mild traumatic brain injuries, do not have a universally accepted definition but there are key features that the experts agree upon; most notably that they are caused by a direct blow, they cause functional disturbances, and that they cannot be explained by another injury or impairment. Most concussions are resolved within a few days but 10-20% have lingering effects that can last for years. In this study, frequency of lingering injury to each brain region was determined from data from thirteen studies and compared to Scheid et. al's frequency of short term injury by brain region using ANOVA …

Physiological And Behavioral Correlates Of Hif-1 Alpha Protein Levels In The Gulf Killifish, Fundulus Grandis, Jasmine Harris May 2020

Physiological And Behavioral Correlates Of Hif-1 Alpha Protein Levels In The Gulf Killifish, Fundulus Grandis, Jasmine Harris

LSU New Orleans Theses and Dissertations

Although the hypoxia-inducible transcription factor (HIF) orchestrates molecular responses to low oxygen, the amount of HIF-1α protein expressed during hypoxia varies among species, individuals, and tissues. This study measured HIF-1α protein levels along with several physiological and behavioral variables in the estuarine fish Fundulus grandis under normoxia (> 7 mg l-1 dissolved oxygen) and hypoxia (1 mg l-1 dissolved oxygen). Fish under hypoxic conditions had higher tissue levels of HIF-1α, hematocrit, blood glucose, blood lactate, frequency of aquatic surface respiration (ASR), and lower activity than normoxic controls. Under hypoxia, HIF-1α abundance in gill was positively correlated with body …

Proposal For Comparative Morphometrics Of Tübingen (Tu) And Tübingen Longfin (Tl) Zebrafish (Danio Rerio), Andrew Draper May 2020

Proposal For Comparative Morphometrics Of Tübingen (Tu) And Tübingen Longfin (Tl) Zebrafish (Danio Rerio), Andrew Draper

University Honors Theses

The TL strain of zebrafish (Danio rerio) originated from the TU strain, and differs in fin pattern with a phenotype predominated by increased fin length. Two genes are known to affect the phenotype: leo and lof. The pattern-affecting leo gene is not believed to affect the growth rate, development, or proportionality of the body. The lof gene does however result in significant increase in fin length compared to the wild-type phenotype of TU. Using populations from both TL and TU genetic strains, development was observed from 48 hours post fertilization through sexual maturity at 90 days post fertilization …
