A Brief Period Of Exercise Improves Cognitive Function After Cardiac Arrest, Holly Stradecki Cohan

Open Access Dissertations

Cardiac arrest effects over half a million people in the United States annually. A lack of brain perfusion results in a global brain ischemia resulting in cell death in several regions including the hippocampus, an area important for learning and memory. Nearly half the survivors of cardiac arrest suffer from cognitive deficits. While there remains no well accepted therapy for these patients, it has been shown that exercise after focal brain ischemia (i.e. stroke) enhances both motor and cognitive function. But this has never been explored in the setting of cardiac arrest. In this study, we determined that a brief …

De Novo Origins Of Multicellularity In Response To Predation, Matthew D. Herron, Joshua M. Borin, Jacob C. Boswell, Jillian Walker, I. Chen Kimberly Chen, Charles A. Knox, Margrethe Boyd, Frank Rosenzweig, William C. Ratcliff

Biological Sciences Faculty Publications

The transition from unicellular to multicellular life was one of a few major events in the history of life that created new opportunities for more complex biological systems to evolve. Predation is hypothesized as one selective pressure that may have driven the evolution of multicellularity. Here we show that de novo origins of simple multicellularity can evolve in response to predation. We subjected outcrossed populations of the unicellular green alga Chlamydomonas reinhardtii to selection by the filter-feeding predator Paramecium tetraurelia. Two of five experimental populations evolved multicellular structures not observed in unselected control populations within ~750 asexual generations. Considerable variation …

Reply To: “Global Conservation Of Phylogenetic Diversity Captures More Than Just Functional Diversity”, Florent Mazel, Matthew W. Pennell, Marc W. Cadotte, Sandra Diaz, Giulio Valentino Dalla Riva, Richard Grenyer, Fabien Leprieur, Arne O. Mooers, David Mouillot, Caroline M. Tucker, William D. Pearse

Ecology Center Publications

Academic biologists have long advocated for conserving phylogenetic diversity (PD), often (but not exclusively) on the basis that PD is a useful proxy for “feature diversity”, defined as the variety of forms and functions represented in set of organisms (see below for an extended discussion of this definition). In a recent paper, we assess the extent to which this proxy (which we coined the “phylogenetic gambit”) holds in three empirical datasets (terrestrial mammals, birds, and tropical marine fishes) when using functional traits and functional diversity (FD) to operationalize feature diversity. Owen et al. offer a criticism of our methods for …

Quantifying And Correcting For Clay Content Effects On Soil Water Measurement By Reflectometers, Jasreman Singh, Tsz Him Lo, Daran Rudnick, Suat Irmak, Humberto Blanco-Canqui

Department of Agricultural and Biological Systems Engineering: Faculty Publications

The presence of clay particles increases the specific surface area of a soil and can affect the calibration of electromagnetic soil water sensors including reflectometers. To quantify and correct for this effect in two relatively new reflectometers, three TDR315 and three CS655 sensors were installed in each of five soils with clay content ranging from 5 to 49%. As the soils were dried in a temperature controlled room, sensor reported soil volumetric water content (θ_v) according to the factory calibration was compared against reference θ_v determined by weighing the soils. Sensor reported θ_v was similar to …

Mosaic Dental Morphology In A Terminal Pleistocene Hominin From Dushan Cave In Southern China, Wei Liao, Song Xing, Dawei Li

KIP Articles

Recent studies reveal high degrees of morphological diversity in Late Pleistocene humans from East Asia. This variability was interpreted as complex demographic patterns with several migrations and possible survival of archaic groups. However, lack of well-described, reliably classified and accurately dated sites has seriously limited understanding of human evolution in terminal Pleistocene. Here we report a 15,000 years-old H. sapiens (Dushan 1) in South China with unusual mosaic features, such as large dental dimensions, cingulum-like structures at the dentine level in the posterior dentition and expression of a “crown buccal vertical groove complex”, all of which are uncommon in modern …

Three Key Factors To Balance When Choosing A Calving Season Based On Profitability, Matthew Stockton, Devin Broadhead

Cornhusker Economics

Cow producers base major decisions such as calving season on expected economic outcomes which include productivity, input costs, personal capability, individual preferences, markets, and so on. Calving systems are generally categorized into three seasons, spring, summer and fall. Many producers select the spring calving season to maximize the weaned calf weight at the end of the summer grass season. Unfortunately this increases feeding costs since extra nutrition is needed in the spring, prior to pastures being opened. Also due to the widespread adoption of this early spring calving, the mass marketing in late fall often results in depressed calf prices …

Spatial-Temporal Variability Of In Situ Cyanobacteria Vertical Structure In Western Lake Erie: Implications For Remote Sensing Observations, Karl Bosse, Michael Sayers, Robert Shuchman, Gary L. Fahnenstiel, Steven A. Ruberg, David L. Fanslow, Dack G. Stuart, Thomas H. Johengen, Ashley M. Burtner

Michigan Tech Publications, Part 1

Remote sensing has provided expanded temporal and spatial range to the study of harmful algal blooms (cyanoHABs) in western Lake Erie, allowing for a greater understanding of bloom dynamics than is possible through in situ sampling. However, satellites are limited in their ability to specifically target cyanobacteria and can only observe the water within the first optical depth. This limits the ability of remote sensing to make conclusions about full water column cyanoHAB biomass if cyanobacteria are vertically stratified. FluoroProbe data were collected at nine stations across western Lake Erie in 2015 and 2016 and analyzed to characterize spatio-temporal variability …

Detecting Rtl Trojans Using Artificial Immune Systems And High Level Behavior Classification, Farhath Zareen

USF Tampa Graduate Theses and Dissertations

Security assurance in a computer system can be viewed as distinguishing between self and non-self. Artificial Immune Systems (AIS) are a class of machine learning (ML) techniques inspired by the behavior of innate biological immune systems, which have evolved to accurately classify self-behavior from non-self-behavior. This work aims to leverage AIS-based ML techniques for identifying certain behavioral traits in high level hardware descriptions, including unsafe or undesirable behaviors, whether such behavior exists due to human error during development or due to intentional, malicious circuit modifications, known as hardware Trojans, without the need fora golden reference model. We explore the use …

Apolipoprotein E4 Alters Astrocyte Fatty Acid Metabolism And Lipid Droplet Formation, Brandon C. Farmer, Jude Kluemper, Lance A. Johnson

Physiology Faculty Publications

Lipid droplets (LDs) serve as energy rich reservoirs and have been associated with apolipoprotein E (APOE) and neurodegeneration. The E4 allele of APOE (E4) is the strongest genetic risk factor for the development of late onset Alzheimer’s disease (AD). Since both E4 carriers and individuals with AD exhibit a state of cerebral lipid dyshomeostasis, we hypothesized that APOE may play a role in regulating LD metabolism. We found that astrocytes expressing E4 accumulate significantly more and smaller LDs compared to E3 astrocytes. Accordingly, expression of perilipin-2, an essential LD protein component, was higher in E4 astrocytes. We then …

Predator Diet Affects Perceived Oviposition Site Quality For Mosquitoes, Brandon Mcdaniel

Honors Theses

Ovipositing freshwater organisms rely primarily on cues to determine site quality (Silberbush and Blaustein 2008) and to select an ideal habitat for their offspring (Resetarits 2014). Characteristics of high quality oviposition sites that yield the greatest fitness for offspring include the absence of predators and high resource availability that allows for optimal growth and development (Kershenbaum et al. 2012). It has been shown that predator presence is a large deterrent of oviposition due to threats of offspring survival, however, there is a little information about the predatory cues mosquitoes experience before ovipositing (Angelon and Petranka 2002). One hypothesis is that …

Astrocytes Infected With Chlamydia Pneumoniae Demonstrate Altered Expression And Activity Of Secretases Involved In The Generation Of Β-Amyloid Found In Alzheimer Disease, Zein Al-Atrache, Danielle B Lopez, Susan Hingley, Denah Appelt

PCOM Scholarly Works

BACKGROUND: Epidemiologic studies strongly suggest that the pathophysiology of late-onset Alzheimer disease (AD) versus early-onset AD has environmental rather than genetic causes, thus revealing potentially novel therapeutic targets to limit disease progression. Several studies supporting the "pathogen hypothesis" of AD demonstrate a strong association between pathogens and the production of β-amyloid, the pathologic hallmark of AD. Although the mechanism of pathogen-induced neurodegeneration of AD remains unclear, astrocytes, a key player of the CNS innate immune response and producer/metabolizer of β-amyloid, have been implicated. We hypothesized that Chlamydia pneumoniae infection of human astrocytes alters the expression of the amyloid precursor protein …

Bulletin of Chinese Academy of Sciences (Chinese Version)

For decades, antimicrobials have played a key role in helping and protecting the sound development of animal husbandry. Undoubtedly, for intensive farming, antibiotics will still be one of the essential strategies for preventing and treating the bacterial infectious disease in a very long time. Nevertheless, due to the widely use of antimicrobials, the resistant bacteria and antimicrobial resistance have emerged, which become a severe challenge threatening the whole public for returning to the "pre-antibiotic era". For comprehensively understanding of this issue, here this study focuses on the pros and cons of using antibiotics in livestock, global experience in balancing the …

Social Ecological Predictors Of Risky Sexual Behavior Among Young Adults, Maureen Muchimba

Journal of Social, Behavioral, and Health Sciences

Most studies on sexual behavior outcomes are restricted to adolescents. However, rates of sexually transmitted diseases (STDs) are highest among young adults. This study examined social–ecological predictors in adolescence that predict risky sexual behavior in young adulthood. Using longitudinal data, logistic regression was used to determine social–ecological factors that predict early sexual debut and a high number of lifetime sexual partners among 3,109 young adults. Risk-taking was associated with early sexual debut and a high number of lifetime sexual partners. Father–child connectedness decreased the odds of early sexual debut and a high number of lifetime sexual. School connectedness also decreased …

Cyanobacterial And Algal Abundance And Biomass In Cave Biofilms And Relation To Environmental And Biofilm Parameters, Slađana Popović, Nataša Nikolić, Jelena Jovanović, Dragana Predojević, Ivana Trbojević, Ljiljana Manić, Gordana Subakov Simić

International Journal of Speleology

Due to life in extreme environments, cyanobacteria and algae from cave biofilms that form at the entrances or deep inside the cave around artificial lights are of increasing interest to many scientists. It is well-known that many phototrophic microorganisms are first to colonize exposed substrata and produce the organic matter on which other biofilm constituents relly. Many studies dealing with phototrophic microorganisms from biofilms focus on the diversity and community composition of cyanobacteria and algae, while quantitative assessments are rarely implemented. Biofilm sampling was conducted in Degurić and Vernjikica Cave located in Western and Eastern Serbia, respectively. Ecological parameters (temperature, …
