The Effects On The Uv Spectra Of H2Poh-Tphp As Dication And Dianion Formation Occurs, Yadira Barreiro, Priya Mohan, Alexis Otero Apr 2012

The Effects On The Uv Spectra Of H2Poh-Tphp As Dication And Dianion Formation Occurs, Yadira Barreiro, Priya Mohan, Alexis Otero

Undergraduate Student Symposium

Porphyrins differ in the nature of their peripheral substitution; β substituted are known as natural porphyrins and meso substituted as synthetic porphyrins. Within the meso substituted porphyrins we studied the H2pOH-TPhP. The UV absorption spectra of this porphyrin is observed and monitored between 350 and 750 nm. The resulting absorption spectra after the creation of the dianion and dication with the respective titrations using NaHCO3/HCl and NaOH/HCl will be explained based on the position of the OH in the phenyl group and contribution to the formation of the respective dication or dianion.

A B Cell Driven Model Of Antibody Response In An Immunocompromised System, Adam Abdulhafid Apr 2012

A B Cell Driven Model Of Antibody Response In An Immunocompromised System, Adam Abdulhafid

Undergraduate Student Symposium

There are many ways in which the body responds to infections. The collective response of the innate and adaptive immune responses is called the immune response. The adaptive response is more sophisticated, and therefore requires greater study to understand it. It is the adaptive response that controls infections and prevents recurring disease. One of the main adaptive responses is the antibody response that can bind to virions and prevent them from infecting cells. Most studies of infection are done based on a single infectious agent and how it interacts with the immune system. In many cases there are multiple infections …

Angiotensin Iii Induced Stat3 Phosphorylation In Cultured Rat Astrocytes, Nancy Sarmiento Apr 2012

Angiotensin Iii Induced Stat3 Phosphorylation In Cultured Rat Astrocytes, Nancy Sarmiento

Undergraduate Student Symposium

Angiotensin (Ang) III is a biologically active metabolite of Ang II with similar effects and receptor binding properties as Ang II. Most Ang III studies delineate physiological effects of the peptide but, the intracellular pathways leading to the actions are unknown and are a focus of ongoing studies in the laboratory. Recently, we showed that Ang III induces mitogen activated protein kinases and astrocyte growth in a similar manner as Ang II. In these studies, we investigated in cultured brainstem rat astrocytes whether Ang III stimulates signal transducer and activators of transcription (STAT) 3. STAT3 is an important link between …

Applications Of Ethical Theories In Evaluating The Use Of Performance Enhancing Drugs, Prasanna Maranthe Apr 2012

Applications Of Ethical Theories In Evaluating The Use Of Performance Enhancing Drugs, Prasanna Maranthe

Undergraduate Student Symposium

Steroid use is a reality in professional and high school sports. Some fall into the traps of peer pressure and some are obsessed with breaking records. However, like most quick fixes, there is a large price to pay. Steroid users risk their own health. But, denouncing steroid use by simply saying, “That’s bad, don’t do it,” will not change attitudes. In order to persuade and appeal to current and future steroid users, focused, lucid, and valid ethical reasoning must be applied, even if that means steroid use cannot be condemned in a black and white, absolutist manner. By admitting and …

Characterization Of The Uv Absroption Spectra Of N-Methylpyrydil Porphyrins, Kevin Winters

Undergraduate Student Symposium

Protonation of phenyl porphyrins induced by THF has been investigated. After ionization, the positive charge was localized in the π-electron system. UV spectras have been studied for the ortho, meso, and para cation positions. Upond acid treatment of N-methyl-2-pyridyl, and N-methyl-3-pyridyl, the soret peak and Q bands showed a shlight red shift, signifying a lowering of energy levels of the excited and unexcited states of the π-electrons. However, the soret peak and Q bands of N-methyl-3-pyridyl showed a slight blue shift. This accounted for the increased solvation of π-electrons at the meso position, which increased the energy level difference between …

Assessing The Importance Of The Chelator Edta On Binding Of An Angiotensin Ii Analog To Neurolysin In Rat Testis And Brain Tissue Utilizing 3-Dimensional Modeling And Radioligand Binding, Andrea L. Lopez, Kira L. Santos, Yaneve Shemesh, Jamala D. Swindle

Undergraduate Student Symposium

Angiotensin II (Ang II) acts in the brain to increase blood pressure and is a major cause of cardiovascular disease and stroke. A novel non-AT1, non-AT2 binding site for ANG II in the brain was recently identified as a membrance bound-variant of the zinc metallopeptidase neurolysin. In the presence of PCMB (P-chloromercuribenzoate) and EDTA (Ethylenediaminetetracetate) 125I-sar1,ile8 Ang II binds with high affinity to neurolysin in rodent brain. To further explore the interaction of angiotensins with neurolysin we evaluated the 3-dimensional crystal structure of neurolysin. In addition we determined the importance of the zinc …

Peeking Behind The Mask Of Tolerance: Investigating Implicit Views Towards Gay Adoption, Christine Harlow Apr 2012

Peeking Behind The Mask Of Tolerance: Investigating Implicit Views Towards Gay Adoption, Christine Harlow

Undergraduate Student Symposium

We examined implicit attitudes (Fazio & Olson, 2003) towards same-sex couples’ rights to adopt. Although there is no clear scientific evidence to suggest that gay couples are less capable of raising adopted children, those opposed to gay adoption argue, from intuition or ideology, that placing adopted children with same-sex parents is detrimental to the children’s well-being. If those opposed to gay adoption base their decision on the well-being of the child rather than the parents’ sexual orientation, it follows that they would also share concern for at-risk children adopted by heterosexual parents and that sexual orientation per se would not …

Paleoceanographic Productivity Reconstructions Using Marine Mammal Bone Collagen, Jonathan H. Gomez Apr 2012

Paleoceanographic Productivity Reconstructions Using Marine Mammal Bone Collagen, Jonathan H. Gomez

Undergraduate Student Symposium

Changes in primary ocean productivity play a key role in determining the structure and biomass yield of the North Pacific ecosystem. Are recent dramatic fluctuations in marine ecosystem productivity a function primarily of industrial and other anthropogenically induced changes or part of larger ecosystem scale processes? Archaeofaunal remains of pinnipeds and cetaceans from the Aleutian Islands, Alaska are used as a proxy for marine productivity changes over decade, century and millennial scales throughout the Holocene. Marine vertebrate remains from several previously excavated well-dated archaeological deposits on Unalaska Island span the period AD 1912-5500 BP. Stable carbon and nitrogen isotope ratios …

To Remove The Hook Or Not: Degradation Rates Of Fishing Hooks: Preliminary Results, John W. Coker, Jesse J. Secord

Undergraduate Student Symposium

Post-release survival is the foundation of sustainability upon which most management plans for Gulf and Atlantic finfish exist. An inherent assumption is that a substantial percentage of fish survive capture. We critically evaluate the merits of leaving hooks in released fish. The work examines the degradation of commonly used hooks in recreational and commercial fisheries. Ten separate hook types, 4 commercial and 6 recreational, were used to represent a variety of fishing applications. Acid solution testing was run for a period of 3 months. Saltwater testing was done for a period of 6 months. These data suggest that seawater may …

The Effects Of Stress And Sleep Restriction On Attention And Inhibitory Task Performance, Brandi Viparina, Isaac Chayo Apr 2012

The Effects Of Stress And Sleep Restriction On Attention And Inhibitory Task Performance, Brandi Viparina, Isaac Chayo

Undergraduate Student Symposium

Stress and sleep deprivation impairs performance on attention and inhibitory tasks. Due to the bidirectional effects of sleep restriction and stress, it is difficult to determine the combined and independent effect of each of these on cognitive performance. In an effort to disentangle the unique contribution of stress and sleep on performance, we sought to examine students during a time in which they are both sleep restricted and stressed. To that end, we employed a repeated measures withinsubject design in which each participant was tested twice, once during a non-exam week and once during exam week. The Stroop and a …

The Influence Of Emotional Stimuli On Response Inhibition, Sarah Yassin Apr 2012

The Influence Of Emotional Stimuli On Response Inhibition, Sarah Yassin

Undergraduate Student Symposium

It has been shown in numerous studies that emotion affects cognition. This study looks at the interaction between emotion regulation and response inhibition. Specifically, it looks at how negative pictures impact one’s performance on a complex task that requires inhibition of an on-going response. This was tested by presenting negative and neutral pictures within the context of a stop signal task while measuring electroencephalograph (EEG) Event Related Potentials (ERPs). We found that there was an increase in the amplitude of an ERP measure of attention to emotional stimuli (the LPP) to negative pictures compared to neutral pictures. We further found …

Indicators Of Relatedness In Adolescent Male Groups: Toward A Qualitative Description, Heidi Hutman, Karolina Anna Konieczna, Emily Kerner, Calli Renee Armstrong, Marilyn Fitzpatrick

The Qualitative Report

Self-determination theorists (SDT) argue that the satisfaction of the need for relatedness is essential for growth and well-being. However, the current research has yet to account for the unique ways in which adolescent males engage in behaviors to fulfill their need for relatedness within their peer groups. This qualitative study investigates relatedness in six 16-to 17-year-old adolescent males. Independent observations of videotape data and a collaborative analysis revealed 13 main indicators of moment-to-moment relatedness. These indicators include expressing belonging, referring to shared experiences, and helping others out. The indicators of relatedness are discussed in the context of SDT, and additional …
