Induction Of Apoptosis By Jfd-Ws In Human Breast Adenocarcinoma Xenograft Implanted Athymic Nude Mice, Janelle Alvarez, Meera Bhalani, Thanigaivelan Kanagasabai Ph.D., Sivanesan Dhandayuthapani Ph.D., Appu Rathinavelu Ph.D.

Undergraduate Student Symposium

Apoptosis (programmed cell death) can be stimulated when a cell has reached its pre-determined lifespan. The intrinsic pathway is typically activated for cell cycle regulation, thus preventing tumor formation. Bcl-2 family proteins can play a pro or anti-apoptotic role by regulating the expression levels and modes of action of other proteins such as caspases, which cleave cell parts until the cell is no longer functional. Many studies are focusing on proteins that regulate the apoptotic pathway, as anomalies may lead to tumor formation. The purpose of this study was to assess effects of a novel water-soluble cancer drug, known as …

Morphological Variation Of The Penis And Cirral As Well As Potential Denticulated Bristle Function In The Barnacle, Chthamalus Stellatus, Dan Schneck

Undergraduate Student Symposium

Many barnacles have phenotypically plastic cirri and penises. We studied this ability in Chthamalus stellatus over a range of wave exposure, height and population density along the John U. Lloyd State Park jetty. We also examined specialized, serrated bristles found on the cirri to determine functionality of these bristles, as well as to document any variation. We observed no meaningful variation in penis or cirrus morphology with wave exposure, height or crowding. However both correlate with body size, which is greatest in the middle of their vertical range. Barnacles in the middle of their vertical range also had more denticulate …

Spiritual And Supernatural Elements Of English Theatre (1550-1612), Mariah Busk

Undergraduate Student Symposium

In “Spiritual and Supernatural Elements of English Theatre (1550-1612)”, I use four plays to examine the secularization of supernatural elements of English theatre during the High Middle Ages and the Early Modern Period. My research shows that in Everyman (c.1500) by Anonymous, The Tragical History of Dr. Faustus (c. 1588) by Christopher Marlowe, Hamlet (c. 1600) by William Shakespeare, and The White Devil (c.1612) by John Webster good and evil characters digress from being religious, spiritual figures to being humanized representations of these figures. Corresponding to this secularization is the loss of a God-like figure and a more common use …

Temperature Dependent Variation In Self-Reported Contagious Yawning Within A Single Season, Melissa Dauzonne, Yana Prilutskaya, Daniel Garcia, Amani Al Barghouti Apr 2015

Temperature Dependent Variation In Self-Reported Contagious Yawning Within A Single Season, Melissa Dauzonne, Yana Prilutskaya, Daniel Garcia, Amani Al Barghouti

Undergraduate Student Symposium

Previous cross-cultural research on humans has shown that self-reported contagious yawning frequency varies between distinct seasons and climate conditions. However, it remains possible that differences in yawning across seasons may be a result of physiological circadian changes across the year. In attempt to address this question, here we discuss the results of a study investigating the variation in the frequency of self-reported contagious yawning within a single season in one geographic location. A total of 142 pedestrians were recruited outdoors during an 18-day period over the summer in an equatorial monsoon climate in southern Florida, USA. Consistent with the thermoregulatory …

Don't Think It, Don't Do It: Controlling Executive Control, Karissa Delorme, Hannah Dean Apr 2015

Don't Think It, Don't Do It: Controlling Executive Control, Karissa Delorme, Hannah Dean

Undergraduate Student Symposium

Self-control involves the ability to control immediate impulses and desires. According to the ego depletion model, self-control is a limited resource. Many studies have found that participants who perform a selfcontrol task show impaired performance on subsequent executive control tasks, such as those measuring working memory and attention. In this study, we hypothesized that individuals who perform a self-control task would subsequently demonstrate poorer inhibitory control as measured in a Stroop and stop signal task. Participants were first given instructions to list their daily activities for five minutes as they either attempted to not think about a white bear (self-control …

Dsc And Tga Analysis On 3-Flowable Dental-Light Cured Restorative Composite, Samon Nazemian Apr 2015

Dsc And Tga Analysis On 3-Flowable Dental-Light Cured Restorative Composite, Samon Nazemian

Undergraduate Student Symposium

Since their introduction in 1996, dental-light cured flowable composites have been used as restorative materials for filling and repairing minimally invasive cavities. They are commonly used because they are insoluble, aesthetic, insensitive to dehydration, easy to manipulate, and reasonably inexpensive. Various brands advertise multiple advantages and are comprised differently. One property prior flowable composites exhibited was a significant polymerization shrinkage, which makes it unsuitable for occlusal wear. In this project, we analyzed the marginal shrinkage and stability of three different types of composites: CLEARFIL MAJESTY ES Flow, Genesis Flowable Light Cure Composite, and GrandioSO Heavy Flow. The composites were cured …

Why Do Patients Who Are Going Blind Lose Their Blue Color Vision First?, Mariana Ferraz Apr 2015

Why Do Patients Who Are Going Blind Lose Their Blue Color Vision First?, Mariana Ferraz

Undergraduate Student Symposium

Retinitis pigmentosa (RP) is a slowly progressive, inherited retinal degeneration affecting roughly 1 in 4000 people, typically resulting in a loss of peripheral and night vision, with most legally blind by age 40[1] . RP is characterized by the apoptosis of retinal rods and cones (photoreceptors). Cones are responsible for central and color vision, while rods provide peripheral and nighttime vision. Over 20 years ago, it was reported that some RP patients initially lose short wavelength cones (i.e., s-cones for blueviolet colors; e.g., imagine a world in which shades of blue look grey), but no further research on this …

Modeling And Simulation Of Caenorhabditis Elegans Chemotaxis In Response To A Dynamic Engineered Bacteria, Divya Pandya

Undergraduate Student Symposium

Parasitic helminthes remain important causative agents of human, plant and animal diseases. Helminthes seek out food sources and navigate toward potential hosts using olfaction of simple chemical cues, a process called chemoattraction. While several studies have examined how nematodes, including Caenorhabditis elegans, behave in response to a chemoattractant, how the characteristics of the chemoattractant affect worm behavior has yet to explored. In this manuscript, we develop a mathematical model to examine how characteristics of common chemoattractants affect movement and behavior in the model nematode C. elegans. Specifically, we model a scenario where a toxic, engineered bacteria designed to …

Source Memory Recognition After A Distractor Task, Rajeev Jaundoo Apr 2015

Source Memory Recognition After A Distractor Task, Rajeev Jaundoo

Undergraduate Student Symposium

Without the language to describe the objects and events in the environment, is it more difficult to encode memories of those objects and events? Based on our previous research, we expected better memory for objects we have the language to label. Specifically, in our study we examined the relationship between language and source memory. First, participants were presented the names of novel animals to learn. Participants were then asked to draw some of the animals they just learned, along with some novel animals as well. This exposed the participants to novel stimuli, but without any language or labels to describe …

Estimating Growth And Mortality In Elasmobranchs: Are We Doing It Correctly?, Brian J. Moe Apr 2015

Estimating Growth And Mortality In Elasmobranchs: Are We Doing It Correctly?, Brian J. Moe

HCNSO Student Theses and Dissertations

The instantaneous mortality rate (M) is an important parameter in elasmobranch management and conservation, but is difficult to estimate directly. Thus, indirect estimates based on relatively easily obtained life history parameters are commonly used. Many indirect methods incorporate one or more parameters from the von Bertalanffy growth model (VBGM), which is often criticized for its inability to describe changes in growth associated with maturity. The Lester growth model (LGM) is a biphasic alternative to the VBGM that incorporates trade-offs between reproduction, growth, and survival, and may therefore more accurately estimate M. I used published data from 29 …

Positive Psychology’S Character Strengths In Addiction-Spirituality Research: A Qualitative Systematic Literature Review, Sahaya G. Selvam Apr 2015

Positive Psychology’S Character Strengths In Addiction-Spirituality Research: A Qualitative Systematic Literature Review, Sahaya G. Selvam

The Qualitative Report

There is an increasing interest in the scientific study of the association between spirituality and recovery from addiction. While most of these studies have provided evidence for a possible relationship, others have explored the underlying mechanisms and meditators in the relationship. However, generally, many studies and reviews have not approached the issue within a specific theoretical framework of mainstream psychology. In an attempt to fill this gap, the review being reported here undertook a Qualitative Systematic Literature Review (QSLR) of addiction-spirituality literature. QSLR is an orderly manner of searching for academic literature, selecting relevant literature following a set of inclusion/exclusion …
