Itch Mediation And How It Differs From Pain, Nechama Rappaport

The Science Journal of the Lander College of Arts and Sciences

Itch, to most, is a common nuisance, although when chronic it can negatively affect quality of life. It is obvious that itch is processed differently than pain, but how it differs is not clear. Researchers have been trying to find a path that specifically mediates itch. They have found that itch is mediated through at least two different pathways: histamine dependent and histamine independent. However, many of the mediators involved in the transduction of itch also mediate pain. Although some itch-specific neurons have been found, the majority of the pruritogenic neurons are also responsive to pain stimuli. Two theories that …

Effects Of Vaccine Preservatives And Adjuvants On Childhood Neurodevelopment, Reut Raveh

The Science Journal of the Lander College of Arts and Sciences

Parental concerns about the safety of childhood vaccinations began in the 1990’s and continue until today. A primary concern of many parents is whether the adjuvants and preservatives added to the vaccines have the potential to cause neurodevelopmental disorders in young children. An overview of various studies was done to determine if thimerosal affects childhood neurodevelopment with studies suggesting that thimerosal potentially causes neurodevelopmental disorders. However, some studies suggest the opposite. As a result it is impossible to conclude whether thimerosal affects childhood neurodevelopment. However, measures should be taken to remove thimerosal from the childhood vaccination schedule. Additionally, the studies …

Oocyte Cryopreservation, Esther Gellis

The Science Journal of the Lander College of Arts and Sciences

Anti-mitotic therapies are a form of therapy used to treat cancer patients. The use of these treatments on females can result in fertility complications. Therefore, prior to treatment, women must seek ways to preserve their ability to conceive children after receiving treatment. This study analyzes the outcomes of oocyte cryopreservation and its many variables. Three important variables that can affect the outcome of oocyte cryopreservation are age, cryopreservation method and cryoprotectants. Evidence indicates that human oocyte cryopreservation can enable a woman to preserve her ability to give birth to a healthy child, following anti-mitotic therapies. Hundreds of babies have been …

Mechanism Of Fecal Bacteriotherapy In Treating Clostridium Difficile Infection And Gi Tract Disorders, Rivka Steinberg

The Science Journal of the Lander College of Arts and Sciences

Clostridium difficile infection, an increasingly prevalent and virulent condition, is often resistant to treatment. Standard antibiotic therapy is rarely efficient when used to treat recurrent C. difficile infection. Fecal microbiota transplantation (FMT) is a safe, effective and inexpensive treatment that has a cure rate of about 90%, according to clinical trials and reports. This approach may also be applicable in treating ulcerative colitis, a type of inflammatory bowel disease, on the basis of the restoration of flora imbalances. Additionally, recent data suggests that a disproportion in composition of the gut microbiome may contribute to obesity. FMT, may restore a healthy …

Cognitive Effects Of Breastfeeding, Abraham Englard

The Science Journal of the Lander College of Arts and Sciences

This paper explores the cognitive effects of breastfeeding through Intelligence Testing and Imaging Testing that compares IQ, success, and brain structure of individuals that were breastfed, formula fed, and both breastfed and formula fed. Intelligence studies available are widespread for all age groups and signify a causal relationship between breastfeeding and intelligence. However, imaging testing is not as extensive, but shows a strong correlation between cognitive development and breastfeeding. The mechanism of breast milk’s impact on cognitive development is at an exploratory phase, with a possibility that docosahexaenoic and arachidonic acids, along with other nutrients found in breast milk, contribute …

A Dietary Approach To Cardiovascular Disease And Cancer: Does A Plant Based Diet Help Prevent And Reverse Cardiovascular Disease And Cancer?, Chana Wircberg

The Science Journal of the Lander College of Arts and Sciences

Modern Western societies seem to suffer from a veritable epidemic of serious diseases, two of the most serious of which are cardiovascular disease and cancer. In contrast, hunter and gatherer groups have a very low incidence of such diseases. Despite the diversity of hunter and gather diets, they all share the same characteristic: the absence of a Western diet. This suggests that there is something uniquely inflammatory about a Western diet, which is high in both fats and carbohydrates. Departures from a Western diet appear to result in better health. Experimental studies have shown that heart disease can be reversed …

How Compatible Is Cow’S Milk With The Human Immune System?, Mindy Knopfler

The Science Journal of the Lander College of Arts and Sciences

Cow’s milk has been part of the human diet for at least 8,000 years and provides a rich source of proteins, lipids, vitamins, and minerals. Despite its longstanding importance in human nutrition, questions remain about how compatible cow’s milk is with our immune system. Cow’s milk allergy (CMA) is the most common form of food allergy in infants and children and cow’s milk has been implicated in a number of immune-mediated disorders. Reviewing current research obtained through Google Scholar and Touro’s library database on CMA and the potential role of cow’s milk in systemic inflammation and autoimmunity reveals a tangle …

Artificial Sweeteners And Weight Gain: Fighting Or Feeding The Obesity Epidemic?, Shanna Frisch

The Science Journal of the Lander College of Arts and Sciences

Our world has developed an obsession with weight control and, as a result, has begun replacing high calorie foods with low-fat and non-caloric substitutes. Artificial sweeteners are a widely used solution to this growing problem. Though the intention when using artificial sweeteners is to lose weight, studies have shown that the opposite sometimes occurs. Researchers attempt to explain this surprising phenomenon with multiple hypotheses. Lack of appetite suppression and reward response may cause individuals to search for more food and to consume more calories. Artificial sweeteners can also have negative affects on biological mechanisms such as resting metabolic rate, as …

The Psychological And Neurological Effectiveness Of Placebo Treatment, Aliza Jeidel

The Science Journal of the Lander College of Arts and Sciences

Placebo effect is an alternative medical approach that doctors utilize in treating health issues. For years, people thought that placebo pills were inert drugs or medically illegitimate measures that have psychological effects on the patient, therefore alleviating the patient’s pain. However, in recent years, with the advent of technology, more studies are involving neurological aspects to the already-proven psychological aspects of the placebo effect. Yet there is still some opposition and much to be proven better on this topic. What is very important is that although there is opposition, there is growing recognition that the placebo effect may actually involve …

Effects Of Moderate Intake Of Alcohol On Coronary Heart Disease, Eli Derdik

The Science Journal of the Lander College of Arts and Sciences

The french paradox is caused by an inconsistency with scientific experimentation: The French have a very high intake of saturated fat and cholesterol, which is associated with coronary heart disease, yet they have un-commensurately low levels of deaths due to this disease. It has been proposed that alcohol, as a part of the French diet, is the factor that helps decrease the risk of heart disease in the French population by 20-30%. Research has been gathered from many medical journals to create a larger and more accurate perspective to determine if alcohol has any effect on coronary heart disease. Experiments …

Recalibration Methodology To Compensate For Changing Fluid Properties In An Individual Nozzle Direct Injection System, Joe D. Luck, Scott A. Shearer, Brian D. Luck, Michael P. Sama

Biosystems and Agricultural Engineering Faculty Publications

Limited advancement of direct injection pesticide application systems has been made in recent years, which has hindered further commercialization of this technology. One approach to solving the lag and mixing issues typically associated with injection-based systems is high-pressure individual nozzle injection. However, accurate monitoring of the chemical concentrate flow rate can pose a challenge due to the high pressure, low flow, and changing viscosities of the fluid. A methodology was developed for recalibrating high-pressure chemical concentrate injectors to compensate for fluid property variations and evaluate the performance of this technique for operating injectors in an open-loop configuration. Specific objectives were …

Encapsulation Of Natural Colorant In Rice Flour Granules, Pornpan Natthawut

Chulalongkorn University Theses and Dissertations (Chula ETD)

The trend of using natural colorants replaced synthetic colorants was increasing in food and cosmetic application. However, the natural colorants had disadvantage on color instability. Usually the color of anthocyanin changes quite quickly after the materials are exposed to various environmental factors including moisture, air and light. In this work, rice granules were used to stabilize roselle, butterfly pea and curcumin extracts. The stabilized natural colorants were then subjected to stability evaluation at various temperatures (room temperature, 4oC and 40oC) for up to 1000 h, and also under light-exposed and light-proof conditions for up to 100 h. The monitoring of …

Bioactive Compounds From Aquilalia Crassna, Garcinia Gracilis And Hydnocarpus Ilicifolia With Antioxidant, Dna Protective And Α-Glucosidase Inhibitory Activities, Chonlakan Supasuteekul

Chulalongkorn University Theses and Dissertations (Chula ETD)

Phytochemical study of the leaves of Aquilaria crassna Pierre ex Lecomte (Thymelaeaceae) led to the isolation of three major constituents, namely, genkwanin 5-O-β-primeveroside, iriflophenone 3,5-C-β-D-diglucoside and iriflophenone 3-C-β-D-glucoside. The leaves of Garcinia gracilis Pierre (Clusiaceae) yielded 5-hydroxymethyl-2-furaldehyde, vanillic acid and apigenin-8-C-α-L-rhamnopyranosyl-(1→2)-β-D-glucopyranoside. The fruits of Hydnocarpus ilicifolia King (Achariaceae) afforded five compounds, namely, chrysoeriol, schweinfurthinol, luteolin, luteolin 5,3'-dimethyl ether and D-pinitol. Their structures were determined by an analysis of spectroscopic data (NMR and HR-ESI-MS) and comparison with previously reported data. Each of these compounds was evaluated for its antioxidant activity using DPPH and superoxide anion radical scavenging assays. Iriflophenone 3-C-β-D-glucoside from …

“My Masculinity Is A Little Love Poem To Myself”: Trans*Masculine College Students’ Conceptualizations Of Masculinities, T.J. Jourian

Dissertations

Men and masculinities studies in higher education are gaining prominence within the literature, illuminating how cisgender men understand and grapple with masculinity on college campuses. Additionally, the increased visibility of trans* students has fueled the expanding scholarship and attention to their experiences, often however centering on White gender-conforming trans* students with little if any focus on their multiple and intersecting identities. This phenomenological study seeks to bridge these two areas of literature, by investigating how trans*masculine students understand, define, and adopt a masculine identity, and how that identity is informed by their various intersecting and salient identities. Dominant masculinities function …

Vocalization Subsystem Responses To A Temporarily Induced Unilateral Vocal Fold Paralysis, Daniel J. Croake

Theses and Dissertations--Rehabilitation Sciences

Healthy voicing is thought to be dependent on a dynamic balance of three interactive subsystems: respiration, phonation, and resonance. Theoretically, multiple patterns of subsystem interactions likely underlie healthy voice production; however surprisingly little quantitative data exists defining the nature of these subsystem production patterns and interactions across individuals.

The central aim of this study was to quantify the interactions of the vocalization subsystems in a non-perturbed and perturbed condition (induced unilateral vocal fold paralysis) in 10 vocally healthy participants. Respiratory inductance plethysmography, laryngeal aerodynamics, and acoustic formant data were used to measure the proportional contributions of, and changes to, the …

Uv Light-Induced Aggregation Of Titania Submicron Particles, Can Zhou, Yashar Bashirzadeh, Timothy A. Bernadowsky Jr., Xiaoyu Zhang

Mechanical & Aerospace Engineering Faculty Publications

In this study, aggregation of TiO₂ (rutile and anatase) submicron particles in deionized (DI) water under ultra-violet (UV) light irradiation was investigated. While no aggregation was observed in the dark, rutile and anatase submicron particles started aggregating upon application of UV light and ceased aggregation in about 2 and 8.4 h, respectively. It has been demonstrated that UV light directly mitigated the particle mobility of TiO₂, resulting in a neutralization effect of the Zeta potential. It was also observed that rutile particles aggregated much faster than anatase particles under UV radiation, indicating that the Zeta potential of …

A Litigator's Guide To The Internet Of Things, Antigone Peyton

Richmond Journal of Law & Technology

Maybe you've heard about the Internet of Things (loT). It's the network of physical objects (or "things") that connect to the Internet and each other and have the ability to collect and exchange data. It includes a variety of devices with sensors, vehicles, buildings, and other items that contain electronics, software, and sensors. Some loT objects have "embedded intelligence," which allows them to detect and react to changes in their physical state. Though there is no specific definition of loT, the concept focuses on how computers, sensors, and objects interact with each other and collect information relating to their surroundings.

Carinata Fame Production Process And Biofuel Oxidation, Benoit Kindo

Honors College Theses

In this experiment, the contribution of a standard production method for biofuels on their oxidative stability was investigated. Peroxide values were measured at different steps of the production process of Brassica carinata and peanut-based biofuels. The washing and drying steps in this production method showed significant increases in peroxide values for both biofuels and was identified as a major contributor of biofuel oxidation. Further analyses of the physical and thermal properties showed a more pronounced affect in the biofuel from Bassica carinata, and indicated an unusual composition much higher in saturated fatty acids much longer than those found in peanut. …

When The Leaves Fall: Modeling Seasonal Variation Of Litter Flux In An Urban Forest, Scott W. Oswald

Honors College Theses

I propose a statistical model to describe the seasonal variation in forest litter flux rates. To examine the effectiveness of the proposed model and to estimate the model parameters, a small set of litter flux data was collected. Data collection was continuous from November 2014 to January 2016. Model parameters were estimated from the data. Using the estimated parameters, the model was applied to an existing dataset to provide some evidence of the model's potential to predict future litter flux rates. While the model did reasonably fit the data, it only had some limited success at prediction. Future research is …

Scalability Of Microscale Fractal-Like Branching Channel Networks, James R. Miller Iii

Honors College Theses

Fractal-like branching channel networks have been shown to offer the advantages of reduced pumping power and lower maximum wall temperatures when employed in the design of microscale heat sinks. Unfortunately, previous literature has been limited to microscale flow networks. In this paper, a microscale flow network will be scaled up to result in a mesoscale flow network and a macroscale flow network. In order to compare the pressure drop across the flow networks of varying scales the results will be nondimensionalized in the form of the Euler number. For a laminar inlet Reynolds number the microscale, mesoscale, and macroscale fractal-like …

An Investigation Of Irish Culinary History Through Manuscript Cookbooks, With Particular Reference To The Gentry Of County Kilkenny (1714-1830), Dorothy Cashman

Doctoral

This thesis argues that Irish culinary manuscripts have a significant contribution to make to an understanding of Irish culinary history. It does so by identifying one particular manuscript, NLI MS 34,952 (Baker) as being representative of the genre but singular in terms of the archival and literary support available for an in-depth study. Analysis of the manuscript is undertaken using a methodology devised by the culinary historian Wheaton for researchers attending her workshops at Radcliffe College, Harvard. In these workshops Wheaton studies historic cookbooks to ascertain what these complex texts can reveal by breaking them down into five categories, that …

Mechanisms Of Native Shrub Encroachment On A Virginia Barrier Island, Joseph Thompson

Theses and Dissertations

Species composition, temperature, soil nutrients, and leaf area index (LAI) were recorded across three encroaching Morella cerifera thicket edges and three free- standing shrubs on Hog Island, Virginia to characterize the effect of shrub thickets on the plant community and microclimate. Electron transport rate (ETR) was taken on shrub leaves to determine if microclimate benefits M. cerifera physiology. Species richness was lowest inside shrub thickets. Soil water content and LAI were higher in shrub thickets compared to grassland. Soil organic matter, N, and C were higher inside shrub thickets. Summer and fall maximum temperatures were more moderate in shrub thickets …

Natural Variation In Maternal Care And Cross-Tissue Patterns Of Oxytocin Receptor Gene Methylation In Rats, Annaliese K. Beery, Lisa M. Mcewen, Julia L. Macisaac, Darlene D. Francis, Michael S. Kobor

Neuroscience: Faculty Publications

Since the first report of maternal care effects on DNA methylation in rats, epigenetic modifications of the genome in response to life experience have become the subject of intense focus across many disciplines. Oxytocin receptor expression varies in response to early experience, and both oxytocin signaling and methylation status of the oxytocin receptor gene (Oxtr) in blood have been related to disordered social behavior. It is unknown whether Oxtr methylation varies in response to early life experience, and whether currently employed peripheral measures of Oxtr methylation reflect variation in the brain. We examined the effects of early life rearing experience …

Sexualization, Sex Discrimination, And Public School Dress Codes, Meredith J. Harbach

Law Faculty Publications

This essay joins the conversation about sexualization, sex discrimination, and public school dress codes to situate current debates within in the broader cultural and legal landscapes in which they exist. My aim is not to answer definitively the questions I pose above. Rather, I ground the controversy in these broader contexts in order to better understand the stakes and to glean insights into how schools, students, and communities might better navigate dress code debates.

Birth City: Race And Violence In The History Of Childbirth And Midwifery In The El Paso-Ciudad Juárez Borderlands, 1907-2013, Heather Marie Sinclair

Open Access Theses & Dissertations

Since the founding of The Maternity Center by midwife Shari Daniels in 1976, thousands of women have traveled from throughout North America to El Paso, Texas to train in midwifery, making the U.S.-Mexico border region the epicenter of the North American home birth movement. Through an analysis of government reports, periodicals, archival documents, and oral histories, this study investigates the complex process through which midwifery and birthing at home, racialized as "primitive" and Mexican by White health officials and reformers in early twentieth-century El Paso, transformed into practices associated with White middle-class women by the century's end. Centered on themes …
