The Effect Of Female Education On Fertility And Infant Health: Evidence From School Entry Policies Using Exact Date Of Birth, Justin Mccrary, Heather Royer

Faculty Scholarship

This paper uses age-at-school-entry policies to identify the effect of female education on fertility and infant health. We focus on sharp contrasts in schooling, fertility, and infant health between women born just before and after the school entry date. School entry policies affect female education and the quality of a woman’s mate and have generally small, but possibly heterogeneous, effects on fertility and infant health. We argue that school entry policies manipulate primarily the education of young women at risk of dropping out of school.

Modelling The Effect Of Asparaginase In Reducing Acrylamide Formation In Biscuits, Monica Anese, Barbara Quarta, Jesus Maria Frias

Articles

The influence of asparaginase on acrylamide formation, as well as colour development, in short dough biscuits was studied. In particular, asparaginase concentration, incubation time and temperature were changed according to an experimental design. As acrylamide formation was found to vary significantly between biscuits obtained by using the same ingredients and process, a mixed effect model was used to model variation of acrylamide concentration. By contrast a fixed effect model was used for colour polynomial analysis. Within the range of study, the overall results allowed the best conditions for minimising acrylamide formation to be found. It can be suggested that acrylamide …

Bioactive Potential And Possible Health Effects Of Edible Brown Seaweeds, Shilpi Gupta, Nissreen Abu-Ghannam

Articles

Marine macroalgae (seaweeds) are rich in bioactive compounds that could potentially be exploited as functional ingredients for both human and animal health applications. Despite the intensive efforts that are being made to isolate and identify new compounds with potential medicinal, health or pharmaceutical activities, very few compounds with real potency are available. Bioactive compounds that are most extensively researched include sulfated polysaccharides, phlorotannins and diterpenes. These compounds have been reported to possess strong anti-viral, anti-tumor and anti-cancer properties. At the same time, the prebiotic health potential of the polysaccharides from seaweeds is also increasingly being studied either by feeding whole …

Phenolic Composition, Antioxidant Capacity And Antibacterial Activity Of Selected Irish Brassica Vegetables, Amit Jaiswal, Gaurav Rajauria, Nissreen Abu-Ghannam, Shilpi Gupta

Articles

Vegetables belonging to the Brassicaceae family are rich in polyphenols, flavonoids and glucosinolates, and their hydrolysis products, which may have antibacterial, antioxidant and anticancer properties. In the present study, phenolic composition, antibacterial activity and antioxidant capacity of selected Brassica vegetables, including York cabbage, Brussels sprouts, broccoli and white cabbage were evaluated after extraction with aqueous methanol. Results obtained showed that York cabbage extract had the highest total phenolic content, which was 33.5, followed by 23.6, 20.4 and 18.4 mg GAE/g of dried weight (dw) of the extracts for broccoli, Brussels sprouts and white cabbage, respectively. All the vegetable extracts had …

Effect Of Processing Conditions On Phytochemical Constituents Of Edible Irish Seaweed Himanthalia Elongata., Sabrina Cox, Nissreen Abu-Ghannam, Shilpi Gupta

Articles

Seaweed iswell recognized as an excellent source of phytochemicals. This study was a preliminary screening to investigate the effects of various food processing methods on the phytochemicals of Himanthalia elongata. Hydrothermal processing was carried out until an edible texture was achieved. The total phenolic content (TPC) of fresh H. elongata was 175.27 mg gallic acid equivalent (GAE)/100 g fresh weight (FW) while boiling significantly reduced the TPC to 25.4 mg GAE/100 g FW
(P < 0.05).A drying pretreatment before boiling reduced the cooking time therefore leading to less leaching of antioxidants upon boiling. In terms of extract, drying of H. elongata followed by boiling had the most significant effect on the phytochemicals as TPC increased by 174%. Boiled extracts had the most effective 2, 2-diphenyl- 1-picrylhydrazyl scavenging activity (EC50 of 12.5 mg/mL). As a comparison, seaweed subjected to the same treatments was studied in terms of antimicrobial activity.Overall, extracts fromfresh H. elongata achieved the highest inhibition.

Estimating The Efficacy Of Mild Heating Processes Taking Into Account Microbial Non-Linearities: A Case Study On The Thermisation Of A Food Simulant, Vasilis Valdramidis, Brijesh Tiwari, Patrick J. Cullen, Alain Kondjoyan, Jan Van Impe

Articles

Traditional and novel approaches for the calculation of the heat treatment efficiency are compared in this work. The Mild Heat value (MH-value), an alternative approach to the commonly used sterilisation, pasteurisation and cook value (F, P, C–value), is calculated to estimate the efficiency of a mild heat process. MH-value is the time needed to achieve a predefined microbial reduction at a reference temperature and a known thermal resistant constant, z, for log-linear or specific types of non log-linear microbial inactivation kinetics. An illustrative example is given in which microbial inactivation data of Listeria innocua CLIP 20-595 are used for estimating …

Effect Of Different Drying Temperatures On The Moisture And Phytochemical Constituents Of Edible Irish Brown Seaweed, Shilpi Gupta, Sabrina Cox, Nissreen Abu-Ghannam

Articles

The effect of different temperatures on the drying kinetics and the phytochemical constituents of edible Irish brown seaweed, Himanthalia elongata were studied. This kinetic study involved the modelling of the terms of Fick’s diffusion equation, for estimation of the diffusion coefficients. The diffusivity coefficient increased from 5.6×10−07-12.2×10−07 m2/s as the drying temperatures increased with an estimated activation energy of 37.2 kJ/mol. The experimental data was also fitted to different empirical kinetic models, Newton, Logarithmic and Henderson-Pabis, and the goodness of fit for the different models was evaluated. The effect of drying temperatures on the phytochemical constituents in seaweed was also …

Application Of Response Surface Methodology For Studying The Influence Of Hydrothermal Processing On The Phytochemical Constituents Of Irish Edible Brown Seaweed, Sabrina Cox

Articles

We used response surface methodology to investigate the effect of time and temperature of hydrothermal processing (blanching) on the phytochemical content, texture and colour of a semi-dried brown seaweed ( Himanthalia elongata ). A central composite design was employed with a hydrothermal processing time of 10 – 30 min and temperature of 60 – 90 ° C. Predicted models were found to be signifi cant for total phenolic content, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity, total fl avonoids, total condensed tannins, texture and colour. The predicted values for each of the responses were in good agreement with experimental values. Processing time had …

The Effect Of Untreated And Enzyme-Treated Commercial Dairy Powders On The Growth And Adhesion Of Streptococcus Mutans, Rachel Halpin, D.B. Brady, E.D. O’Riordan, M. O’Sullivan

Articles

Dental caries is a common bacterial infection, but the progression of this disease can be delayed by preventing initial attachment of cariogenic bacteria such as Streptococcus mutans to tooth surfaces. This study firstly compares the effect of untreated (UT) and enzyme-treated (ET) dairy powders on the adherence of S. mutans to hydroxylapatite (HA), an analogue of tooth enamel. A fluorescence-based method was used to quantify adherence of S. mutans to HA both in the presence (S-HA) and absence (PBS-HA) of saliva. Secondly, binding of proteins present in the test materials to HA was quantified using bicinchonic acid assays and SDS-PAGE. …

Molecular Characterization Of Multidrug-Resistant Escherichia Coli Isolates From Irish Cattle Farms, Maria Karczmarczyk, Ciara Walsh, Rosemarie Slowey, Nola Leonard, Seamus Fanning

Articles

This study describes the genotypic characteristics of a collection of 100 multidrug-resistant (MDR) Escherichia coli strains recovered from cattle and the farm environment in Ireland in 2007. The most prevalent antimicrobial resistance identified was to streptomycin (100%), followed by tetracycline (99%), sulfonamides (98%), ampicillin (82%), and neomycin (62%). Resistance was mediated predominantly by strA-strB (92%), tetA (67%), sul2 (90%), blaTEM (79%), and aphA1 (63%) gene markers, respectively. Twenty-seven isolates harbored a class 1 integrase (intI1), while qacE1 and sul1 markers were identified in 25 and 26 isolates, respectively. The variable regions of these integrons contained aminoglycoside, trimethoprim, and [1]-lactam resistance …

Efficacy Of Biocides Used In The Modern Food Industry To Control Salmonella Enterica, And Links Between Biocide Tolerance And Resistance To Clinically Relevant Antimicrobial Compounds, Orla Condell, Carol Iversen, Shane Cooney, Karen Power, Ciara Walsh, Catherine Burgess, Seamus Fanning

Articles

Biocides play an essential role in limiting the spread of infectious disease. The food industry is dependent on these agents, and their increasing use is a matter for concern. Specifically, the emergence of bacteria demonstrating increased tolerance to biocides, coupled with the potential for the development of a phenotype of cross-resistance to clinically important antimicrobial compounds, needs to be assessed. In this study, we investigated the tolerance of a collection of susceptible and multidrug-resistant (MDR) Salmonella enterica strains to a panel of seven commercially available food-grade biocide formulations. We explored their abilities to adapt to these formulations and their active …

Evolutionary History And Spread Of Multidrug Resistant Inchi1 Plasmids In Salmonella Typhi, Kathryn Holt, Minh Duy Phan, Stephen Baker, Pham Thanh Duy, Tran Vu Thieu Nga, Satheesh Nair, Arthur Keith Turner, Ciara Walsh, Seamus Fanning, Sinead Farrell-Ward, Shanta Dutta, François-Xavier Weill, Julian Parkhill, Gordon Dougan, John Wain

Articles

Typhoid fever, infection with Salmonella enterica serovar Typhi (S. Typhi), remains a serious health concern in many parts of the world, particularly where sanitation is poor. While vaccines against S. Typhi are available, coverage in endemic regions is low, leaving antimicrobial therapy central to disease control. Unfortunately, drug resistant S. Typhi emerged in the mid-1970s and multi-drug resistance (MDR) is now a significant problem in many typhoid endemic areas. In the S. Typhi population, MDR is almost exclusively conferred by self-transmissible IncHI1 plasmids carrying a suite of antimicrobial resistance genes. We compared eight IncHI1 plasmid sequences and identified single nucleotide …

Modeling Measurement Error In Tumor Characterization Studies, Cyril Rakovski, Daniel J. Weisenberger, Paul Marjoram, Peter W. Laird, Kimberly D. Siegmund

Mathematics, Physics, and Computer Science Faculty Articles and Research

Background: Etiologic studies of cancer increasingly use molecular features such as gene expression, DNA methylation and sequence mutation to subclassify the cancer type. In large population-based studies, the tumor tissues available for study are archival specimens that provide variable amounts of amplifiable DNA for molecular analysis. As molecular features measured from small amounts of tumor DNA are inherently noisy, we propose a novel approach to improve statistical efficiency when comparing groups of samples. We illustrate the phenomenon using the MethyLight technology, applying our proposed analysis to compare MLH1 DNA methylation levels in males and females studied in the Colon …

The Energy Landscape Analysis Of Cancer Mutations In Protein Kinases, Anshuman Dixit, Gennady M. Verkhivker

Mathematics, Physics, and Computer Science Faculty Articles and Research

The growing interest in quantifying the molecular basis of protein kinase activation and allosteric regulation by cancer mutations has fueled computational studies of allosteric signaling in protein kinases. In the present study, we combined computer simulations and the energy landscape analysis of protein kinases to characterize the interplay between oncogenic mutations and locally frustrated sites as important catalysts of allostetric kinase activation. While structurally rigid kinase core constitutes a minimally frustrated hub of the catalytic domain, locally frustrated residue clusters, whose interaction networks are not energetically optimized, are prone to dynamic modulation and could enable allosteric conformational transitions. The results …

Cooperative Learning And Peer Tutoring To Improve Third-Grade Students’ Test Scores On Grade-Level Assessment, Francina Y. Thurston

Abraham S. Fischler College of Education ETD Archive

This applied dissertation was designed to utilize learning strategies that emphasized small-group instructions where students work together cooperatively and with peers to achieve mastery. Traditionally, the classroom practices used in this school lent themselves primarily to whole-class instructions that emphasized competitive and individualistic goals rather than small groups and cooperative practices. The multistrategy used in this study sought to shift the focus of classroom instructions away from what was traditional. However, the introduction of the multistrategy that called for small group teaching required training for teachers and students.

The writer developed several solution strategies that trained students and teachers in …

Rapid Identification Of Oil Contaminated Soils Using Visible Near Infrared Diffuse Reflectance Spectroscopy, Somsubhra Chakraborty

LSU Doctoral Dissertations

Initially, 46 petroleum contaminated and non-contaminated soil samples were collected and scanned using visible near-infrared diffuse reflectance spectroscopy (VisNIR DRS) at three combinations of moisture content and pretreatment. The VisNIR spectra of soil samples were used to predict total petroleum hydrocarbon (TPH) content using partial least squares (PLS) regression and boosted regression tree (BRT) models. The field-moist intact scan proved best for predicting TPH content with a validation r2 of 0.64 and relative percent difference (RPD) of 1.70. Those 46 samples were used to calibrate a penalized spline (PS) model. Subsequently, the PS model was used to predict soil TPH …

Revolutionary Republics: U.S. National Narratives And The Independence Of Latin America, 1810-1846, James Weldon Long

LSU Doctoral Dissertations

Revolutionary Republics analyzes how U.S. literature depicted the independence of Latin America, focusing on the period from the beginning of the Spanish American revolutions in 1810 to the outbreak of the U.S.-Mexican War in 1846. During this brief timespan, the nation’s literature featured a radical transition in which the independent republics of Latin America shifted from being viewed as “southern brethren” of the United States, a term used by such prominent public figures as Daniel Webster and John Quincy Adams, to hostile enemies allegedly in need of assistance from their northern neighbor. This reversal exposes a contradiction between the imperialist …
