A Scalable Field Study Protocol And Rationale For Passive Ambient Air Sampling: A Spatial Phytosampling For Leaf Data Collection, Tonny J. Oyana, Slawomir M. Lomnicki, Chuqi Guo, Stephania A. Cormier

Faculty Publications

© 2017 American Chemical Society. Stable, bioreactive, radicals known as environmentally persistent free radicals (EPFRs) have been found to exist on the surface of airborne PM2.5. These EPFRs have been found to form during many combustion processes, are present in vehicular exhaust, and persist in the environment for weeks and biological systems for up to 12 h. To measure EPFRs in PM samples, high volume samplers are required and measurements are less representative of community exposure; therefore, we developed a novel spatial phytosampling methodology to study the spatial patterns of EPFR concentrations using plants. Leaf samples for laboratory PM analysis …

Influence Of Two Ovulation-Inducing Agents On The Pituitary Response And Follicle Blood Flow In Mares, Y. L. Boakari, J. C. Ferreira, H. S. Canesin, D. L. Thompson, F. S. Lima, J. C.F. Pantoja, C. Meira

Faculty Publications

© 2017 The objective of the current study was to evaluate the effects of deslorelin and hCG, two ovulation-inducing therapies, on LH surge and follicle vascularity in mares. Thirty mares were either treated with 1.5 mg IM of deslorelin, 2,500 IU IV of hCG or 2 mL IM of NaCl 0.9% (GnRH, hCG and Saline groups, respectively). Power-flow Doppler examination and blood collection were performed every hour during the first 12 hours after treatment (H0) and every six hours between hours 12 (H12) and 30 (H30) after treatment. Moreover, endpoints were evaluated every hour through the last six hours before …

Whey Protein Isolate Hydrogels And Their Uses, James E Henry, Mia Dvora

College of Engineering Patents

A biodegradable hydrogel has been made based on high concentrations of whey protein isolate (WPI). WPI gels of different compositions were fabricated by thermally inducing gelation of high-concentration suspensions of protein, and characterized for compressive strength and modulus, hydration swelling and drying properties, mechanical behavior change due to polysaccharide additives, and intrinsic pore network structure. The gels were shown to be compatible with bone cells and could be used as bone tissue scaffolds. In addition, WPI fibers were produced by electrospinning. Several additives could be incorporated into the WPI gels, including structural additives, growth factors, amino acids, etc. The WPI …

Copyright © 2017 The Authors, some rights reserved. Climate change is a well-documented driver of both wildlife extinction and disease emergence, but the negative impacts of climate change on parasite diversity are undocumented. We compiled the most comprehensive spatially explicit data set available for parasites, projected range shifts in a changing climate, and estimated extinction rates for eight major parasite clades. On the basis of 53, 133 occurrences capturing the geographic ranges of 457 parasite species, conservative model projections suggest that 5 to 10% of these species are committed to extinction by 2070 from climate-driven habitat loss alone. We find …

Characteristics Of Ovarian Cancer Detection By A Near-Infrared Fluorescent Probe Activated By Human Nad(P)H: Quinone Oxidoreductase Isozyme 1 (Hnqo1), Yuko Nakamura, Zhenhua Shen, Toshiko Harada, Tadanobu Nagaya, Kazuhide Sato, Shuhei Okuyama, Fusa Ogata, Peter L. Choyke, Robin L. Mccarley, Hisataka Kobayashi

Faculty Publications

© Nakamura et al. Near-infrared (NIR) fluorescent probes are ideal for in vivo imaging, because they offer deeper tissue penetration by the light and lower background autofluorescence than fluorophores that emit in the visible range. Q3STCy is a newly synthesized, NIR light-emitting probe that is activated by an enzyme commonly overexpressed in tumor cells, human nicotinamide adenine dinucleotide (phosphate): quinone oxidoreductase isozyme 1, known as hNQO1 or DT-diaphorase. The purpose of this study is to compare the sensitivity of detecting peritoneal ovarian cancer metastasis (POCM) with Q3STCy and gGlu-HMRG, a green fluorescent probe, upon their surface application. In vitro uptake …

Alu Insertion Polymorphisms As Evidence For Population Structure In Baboons, Mark Batzer, Cody J. Steely, Jerilyn A. Walker, Vallmer E. Jordan, Thomas O. Beckstrom, Cullen L. Mcdaniel, Corey P.

Male dispersal from the natal group at or near maturity is a feature of most baboon (Papio) species. It potentially has profound effects upon population structure and evolutionary processes, but dispersal, especially for unusually long distances, is not readily documented by direct field observation. In this pilot study, we investigate the possibility of retrieving baboon population structure in yellow (Papio cynocephalus) and kinda (Papio kindae) baboons from the distribution of variation in a genome-wide set of 494 Alu insertion polymorphisms, made available via the recently completed Baboon Genome Analysis Consortium. Alu insertion variation in a mixed …

Integrating Soil Silicon Amendment Into Management Programs For Insect Pests Of Drill-Seeded Rice, James M. Villegas, Michael O. Way, Rebecca A. Pearson, Michael J. Stout

Faculty Publications

© 2017 by the authors. Licensee MDPI, Basel, Switzerland. Silicon soil amendment has been shown to enhance plant defenses against insect pests. Rice is a silicon-accumulating graminaceous plant. In the southern United States, the rice water weevil and stem borers are important pests of rice. Current management tactics for these pests rely heavily on the use of insecticides. This study evaluated the effects of silicon amendment when combined with current management tactics for these rice insect pests in the field. Field experiments were conducted from 2013 to 2015. Rice was drill-planted in plots subjected to factorial combinations of variety (conventional …

Role Of Inward Rectifier Potassium Channels In Salivary Gland Function And Sugar Feeding Of The Fruit Fly, Drosophila Melanogaster, Daniel R. Swale, Zhilin Li, Felix Guerrero, Adalberto A. Pérez De León, Lane D. Foil

Faculty Publications

© 2016 The Authors The arthropod salivary gland is of critical importance for horizontal transmission of pathogens, yet a detailed understanding of the ion conductance pathways responsible for saliva production and excretion is lacking. A superfamily of potassium ion channels, known as inward rectifying potassium (Kir) channels, is overexpressed in the Drosophila salivary gland by 32-fold when compared to the whole body mRNA transcripts. Therefore, we aimed to test the hypothesis that pharmacological and genetic depletion of salivary gland specific Kir channels alters the efficiency of the gland and reduced feeding capabilities using the fruit fly Drosophila melanogaster as a …

Effect Of Dietary Salt Intake On Epithelial Na+ Channels (Enac) In Vasopressin Magnocellular Neurosecretory Neurons In The Rat Supraoptic Nucleus, Kaustubh Sharma, Masudul Haque, Richard Guidry, Yoichi Ueta, Ryoichi Teruyama

Faculty Publications

© 2017 The Authors. The Journal of Physiology published by John Wiley & Sons Ltd on behalf of The Physiological Society Key points: A growing body of evidence suggests that epithelial Na+ channels (ENaCs) in the brain play a significant role in the regulation of blood pressure; however, the brain structures that mediate the effect are not well understood. Because vasopressin (VP) neurons play a pivotal role in coordinating neuroendocrine and autonomic responses to maintain cardiovascular homeostasis, a basic understanding of the regulation and activity of ENaC in VP neurons is of great interest. We show that high dietary salt …

Cannibalism And Infectious Disease: Friends Or Foes?, Benjamin G. Van Allen, Forrest P. Dillemuth, Andrew J. Flick, Matthew J. Faldyn, David R. Clark, Volker H.W. Rudolf, Bret D. Elderd

Faculty Publications

© 2017 by The University of Chicago. Cannibalism occurs in a majority of both carnivorous and noncarnivorous animal taxa from invertebrates to mammals. Similarly, infectious parasites are ubiquitous in nature. Thus, interactions between cannibalism and disease occur regularly. While some adaptive benefits of cannibalism are clear, the prevailing view is that the risk of parasite transmission due to cannibalism would increase disease spread and, thus, limit the evolutionary extent of cannibalism throughout the animal kingdom. In contrast, surprisingly little attention has been paid to the other half of the interaction between cannibalism and disease, that is, how cannibalism affects parasites. …

Effect Of Metabolic Status On Conceptus–Maternal Interactions On Day 19 In Dairy Cattle: Ii. Effects On The Endometrial Transcriptome, Stefan Bauersachs, Constantine A. Simintiras, Roger G. Sturmey, Stefan Krebs, Jochen Bick, Helmut Blum, Eckhard Wolf, Pat Lonergan, Niamh Forde

Faculty Publications

The aim of this study was to test the hypothesis that the metabolic stresses associated with lactation alter the ability of the endometrium to respond appropriately to the conceptus by examining endometrial gene expression on day 19 of pregnancy. Immediately after calving, primiparous Holstein cows with similar production and fertility estimated breeding values were randomly divided into two groups and either dried off (i.e. never milked) immediately or milked twice daily. Approximately 65–75 days postpartum, grade 1 blastocysts recovered from superovulated Holstein heifer donors (n = 5) were transferred (1 per recipient) into lactating (n = 11) and nonlactating (n …

Application Of An Advanced Maximum Likelihood Estimation Restoration Method For Enhanced-Resolution And Contrast In Second-Harmonic Generation Microscopy, Mayandi Sivaguru, Mohammad M.

Second-harmonic generation (SHG) microscopy has gained popularity because of its ability to perform submicron, label-free imaging of noncentrosymmetric biological structures, such as fibrillar collagen in the extracellular matrix environment of various organs with high contrast and specificity. Because SHG is a two-photon coherent scattering process, it is difficult to define a point spread function (PSF) for this modality. Hence, compared to incoherent two-photon processes like two-photon fluorescence, it is challenging to apply the various PSF-engineering methods to improve the spatial resolution to be close to the diffraction limit. Using a synthetic PSF and application of an advanced maximum likelihood estimation …

Estimating Parasite Host Range, Tad Dallas, Shan Huang, Charles Nunn, Andrew W. Park, John M. Drake

Faculty Publications

© 2017 The Author(s) Published by the Royal Society. All rights reserved. Estimating the number of host species that a parasite can infect (i.e. host range) provides key insights into the evolution of host specialism and is a central concept in disease ecology. Host range is rarely estimated in real systems, however, because variation in species relative abundance and the detection of rare species makes it challenging to confidently estimate host range. We applied a non-parametric richness indicator to estimate host range in simulated and empirical data, allowing us to assess the influence of sampling heterogeneity and data completeness. After …

Effects Of Elicitor Induced Host Plant Resistance On Lepidopteran Insecticide Efficacy, Abigail Cox

LSU Master's Theses

Soybean looper (SBL), Chrysodeixis includens (Walker), is an important defoliating Lepidopteran pest of southern U.S. soybean and utilizes other agronomic crops and weeds as hosts. With increasing resistance to insecticides, alternative control strategies such as induced host plant resistance were evaluated against SBL. Jasmonic acid (JA) is an elicitor of host plant resistance, and was selected to determine its fit in an IPM plan for SBL. JA was applied to the top of meridic SBL diet and fed to SBL; no effects were found. JA applied as an exogenous elicitor to cotton, sweet potato, okra, cowpea, and soybean did result …

Rice Hull Bioreactor For Recirculating Aquaculture, Marlon A. Greensword

LSU Doctoral Dissertations

The engineering of floating media biofilters has been optimized over the years. The backwashing process has made them more energy and water efficient. Likewise, moving bed bioreactors (MBBR) are gaining interest and popularity because they are relatively affordable to build. Yet, developing countries’ aquaculture production remains largely excluded from the advances made in recirculating aquaculture systems (RAS). This discrepancy is partially driven by the high costs of media such plastic beads and Kaldnes (KMT) media, commonly used in MBBR.

This dissertation evaluates the usability and profitability of rice hulls (RH), an abundant by-product in many developing nations, as a sinking …

Epigenetic Response Of Imprinted Domains During Carcinogenesis, Corey L. Bretz, Ingeborg M. Langohr, Joomyeong Kim

Faculty Publications

© 2017 The Author(s). Background: Imprinted domains have been identified as targets for aberrant DNA methylation during carcinogenesis, but it remains unclear when these epigenetic alterations occur and how they contribute to tumor progression. Epigenetic instability at key cis-regulatory elements within imprinted domains can concomitantly activate proto-oncogenes and turn off tumor suppressor genes. Thus, to further characterize the epigenetic response of imprinted domains during carcinogenesis, we compared the stability of DNA methylation at a variety of cis-regulatory elements within imprinted domains in two fundamentally different mouse tumors, benign and malignant, induced by the KrasG12D mutation. Results: We report that imprinted …

A Preliminary Study To Evaluate Issues Involved Under In Vivo Conditions Of A Delivery System Containing Immobilized Lactobacillus Plantarum Ncimb 8826 On Rice Bran Fiber Extract, Chen Liu

LSU Master's Theses

Gut diseases like diarrhea, irritable bowel symptoms, and inflammatory bowel disease (IBD) can be treated with probiotics therapy. Probiotics have been recognized for their ability to promote the development of gut health and improve immune system. However, a difficulty involved with the use of probiotics is the need for and the ability to deliver a sufficient concentration of viable probiotic to the appropriate site. This can be difficult since the most common (and probably easiest) method of delivering the probiotic is orally. As such, the probiotic must be capable of surviving the hostile conditions of passage through the G.I. tract. …

An Initial Psychometric Evaluation Of The Korean Version Of The Matson Evaluation Of Social Skills With Youngsters-Ii (K-Messy-Ii), Jina Jang

LSU Doctoral Dissertations

Social skills impairment in autism spectrum disorder (ASD) is often considered a hallmark of the disorder. Impairments in social skills impede the development of meaningful social relationships in individuals with ASD. As children get older, social relationships and environments become more complex, further increasing social skills impairments and distress. Although social skill training has received a lot of attention in the last decade, more reliable and valid social skills measures that are adapted to use in the ASD population are needed. Given that social norms and expectations differ across cultures, more culturally valid measures are needed. The Matson Evaluation of …

Reproductive And Metabolic State Differences In Olfactory Responses To Amino Acids In A Mouth Brooding African Cichlid Fish, Alexandre A. Nikonov, Julie M. Butler, Karen E. Field, John Caprio, Karen P. Maruska

Faculty Publications

© 2017. Published by The Company of Biologists Ltd | Journal of Experimental Biology. Olfaction mediates many crucial life-history behaviors such as prey detection, predator avoidance, migration and reproduction. Olfactory function can also be modulated by an animal's internal physiological and metabolic states. While this is relatively well studied in mammals, little is known about how internal state impacts olfaction in fishes, the largest and most diverse group of vertebrates. Here we apply electroolfactograms (EOGs) in the African cichlid fish Astatotilapia burtoni to test the hypothesis that olfactory responses to food-related cues (i.e. L-amino acids; alanine and arginine) vary with …

Repeated Evolution Of Vertebrate Pollination Syndromes In A Recently Diverged Andean Plant Clade, Laura P. Lagomarsino, Elisabeth J. Forrestel, Nathan Muchhala, Charles C. Davis

Faculty Publications

© 2017 The Author(s). Evolution © 2017 The Society for the Study of Evolution. Although specialized interactions, including those involving plants and their pollinators, are often invoked to explain high species diversity, they are rarely explored at macroevolutionary scales. We investigate the dynamic evolution of hummingbird and bat pollination syndromes in the centropogonid clade (Lobelioideae: Campanulaceae), an Andean-centered group of ∼550 angiosperm species. We demonstrate that flowers hypothesized to be adapted to different pollinators based on flower color fall into distinct regions of morphospace, and this is validated by morphology of species with known pollinators. This supports the existence of …
