Effects Of Colored Words On Memory Retention, Adriana Gutierrez

Undergraduate Student Symposium

Color seems to have an impact in our everyday lives. Memory color is a phenomenon in which an object's characteristic color enhances our memory retention. The objective of the present study is to examine which color can best facilitate memory retention. A sample of 30 participants (15 males and 15 females) were recruited from Nova Southeastern University. The participants were tested on their ability to recall a list of 20 words in the colors blue, green, orange, and red. Participants were also tested to determine what color they would be able to best recall. The list of 20 words included …

The Effects Of The Herbal Enzyme Bromelain Against Breast Cancer Cell Line Gi101a, Alexandra Paroulek

Undergraduate Student Symposium

Bromelain is a proteinase derived from the stem of pineapple and has been studied for its anti-inflammatory, antithrombotic, and antimetastatic properties. Bromelain has also been known to significantly reduce local tumor growth and to raise the impaired cytotoxicity of monocytes in the immune system against tumor cells. The goal of this project is to advance the mechanistic knowledge of herbal remedies and to confirm the already known antimetastatic properties of Bromelain. Standardization of MTS assay to check the cell viability is in progress. To test the cytotoxic effects of Bromelain, GI101A breast cancer cells cultured to the required confluency of …

What You Can’T See Can Hurt You! Bacterial Invasion At Nsu, Samarah Al-Jamali

Undergraduate Student Symposium

College campuses are typically areas where large numbers of students from diverse geographical areas converge. Close contact in public places such as classrooms, restrooms, and computer labs is common. Illnesses quickly spread through a college campuses population. Many germs are spread via respiratory droplets which can survive on surfaces for hours and even days. I sampled 14 separate locations at NSU to see which surfaces harbored the most bacteria. Bacterial samples were collected using sterile Q-tips which were swabbed over a one square inch area for approximately 10 seconds. The Q- tips were then used to transfer any bacteria present …

Effects Of Beach Renourishment On Inshore Macroinfauna Off John U. Lloyd Beach State Park, Broward County, Fl, Jessica Boyd

Undergraduate Student Symposium

The marine benthic macrofauna at John U. Lloyd Beach State Park (Broward Co., FL) has been surveyed at intervals since 1987 to examine effects of periodic beach renourishments. The current study followed the most recent renourishment, which ran from May 2005 to February 2006. A total of 20 quantitative sediment core samples (926.667 cm³) were taken from four sites (5 replicates per site), ~100 m offshore at depths of 2-5 m in May 2007. Samples were fixed in 10% seawater formalin with Rose Bengal stain, and subsequently passed through a 0.5-mm-mesh sieve and transferred to 70% ethanol in …

Drowned, Amy Carol Harvey

Undergraduate Student Symposium

Written by Amy Harvey in 2007, this poem offers more than meets the eye. The poem is actually an allegory. Its allegorical meaning is based on the true experiences of the author. Here the experience is given a different location, which aids indirectly to the poem's explanation. This poem was created for personal reflection and healing. In sharing it with others, it is the author's hope that those suffering from sexual abuse will find their voice and demand to be heard.

Purification Of Photosystem Proteins From Spinach Leaves, Anisa Andoni, Hai Pham, Priya Somnaran

Undergraduate Student Symposium

Photosystems are protein-pigment complexes responsible for the conversion of light energy into an electron flow in plants. There are two photosystems called photosystem I and photosystem II. Photosystem II is responsible for splitting water molecules into protons and oxygen. In this work, we have used a biochemical protocol to purify photosystems from spinach leaves by detergent solubilization and centrifugation. The photosystem II activity was measured using a Clarke-type oxygen electrode as an indicator for its intactness and purity. This protocol provides us a tool to compare the photosystem protein from spinach with other species.

Is There A Gender Difference Regarding Perceived Efficacy Of Openly Gay Tutors?, Randy Denis

Undergraduate Student Symposium

Research has shown that many college students have more negative attitudes toward homosexuals than toward other minority groups (Liang and Alimo, 2005), even when they do not openly endorse homophobic attitudes (Nosek, 2007). For example, lectures given by homosexuals were rated as having lower quality than identical lectures given by heterosexuals, possibly demonstrating subtle prejudice (Ewing, Stukas and Sheehan, 2003). In addition, recent findings indicate that heterosexual women tend to have a more favorable perception than heterosexual men of male homosexuality (Herek, 1998). In a between-participants design, forty heterosexual undergraduate students will be exposed to a male tutor with a …

Biodegradation And Partitioning Of Triclosan From A Model Municipal Waste Water Treatment Plant, Besty Jacob

Undergraduate Student Symposium

Triclosan is the commercial name of 5-chloro-2-(2,4-dichlorophenoxy)phenol), an antibacterial and antifungal compound used in a variety of household products. Even at low levels, 0.03 to 0.15% by weight, Triclosan is effective at killing bacteria. Products include soaps, toothpaste, shampoos, tissue paper, and cosmetics. There is a growing trend among manufacturers of diverse products to add the antimicrobial as a marketing edge regardless of its utility. Recent studies indicate triclosan is more persistent in the environment than initially reported. In order to study the effectiveness of wastewater treatment on the degradation of triclosan, a small scale water treatment process was duplicated. …

The Effects Of Laughter On Attention, Raquel Sanchez, Marcia Garcia

Undergraduate Student Symposium

Laughter is a cardinal part of human behavior: it is rooted within personality, functions within social dynamics, and is mediated through a species physiological form. Numerous studies have depicted the benefits of laughter (Martin, 2002; Kimata, 2007), but none have thoroughly analyzed its role within cognition. Cognition is required to incite laughter in the instances where humor appreciation must be delineated. Accordingly, in instances where a cognitive task occurs concurrently with humorous stimuli, there is potentially a competition for attentional resources, thereby reducing cognitive abilities during humor processing. The primary goal of the current proposal is to utilize brain electroencephalographic …

Reducing Carbon Dioxide Levels Through Carbon Sequestration, Mari Holderby, Hira Hussain, Sebastian Jofre, Aurea Mendez

Undergraduate Student Symposium

There has been a growing interest as to what is identified as global warming over the past five years. Studies have demonstrated that the earth’s atmosphere has become warmer thanks to the increasing levels of carbon dioxide, which trap heat that would normally exit into outer space. Much focus has additionally been placed on the causes of this phenomenon, such as the burning of fossil fuels, using coal-fired power plants, and deforestation. The purpose of this research is to discuss how carbon dioxide emissions can be reduced by the use of carbon sequestration. The significant challenge being addressed by this …

Identifying Selected Regions From Heterozygosity And Divergence Using A Light-Coverage Genomic Dataset From Two Human Populations, T. K. Oleksyk, Kai Zhao, Francisco M. De La Vega, Dennis A. Gilbert, Stephen J. O'Brien, Michael W. Smith

Biology Faculty Articles

When a selective sweep occurs in the chromosomal region around a target gene in two populations that have recently separated, it produces three dramatic genomic consequences: 1) decreased multi-locus heterozygosity in the region; 2) elevated or diminished genetic divergence (F_ST) of multiple polymorphic variants adjacent to the selected locus between the divergent populations, due to the alternative fixation of alleles; and 3) a consequent regional increase in the variance of F_ST (S²F_ST) for the same clustered variants, due to the increased alternative fixation of alleles in the loci surrounding the selection target. In …

Background:

Over the past years a variety of host restriction genes have been identified in human and mammals that modulate retrovirus infectivity, replication, assembly, and/or cross-species transmission. Among these host-encoded restriction factors, the APOBEC3 (A3; apolipoprotein B mRNA-editing catalytic polypeptide 3) proteins are potent inhibitors of retroviruses and retrotransposons. While primates encode seven of these genes (A3A to A3H), rodents carry only a single A3 gene.

Results:

Here we identified and characterized several A3 genes in the genome of domestic cat (Felis catus) by analyzing the genomic A3 locus. The cat genome presents one A3H gene and three …

Who's Eating Whom? Identification And Quantification Of Deep-Pelagic Prey Fishes In The North Atlantic Ocean, A. Heger, Tracey Sutton

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Understanding the structure and functioning of marine ecosystems requires accurate knowledge of trophic interactions. Trophic ecology studies generally underestimate prey diversity due to the difficulties imposed by digestion. Further, this degradation leads to uncertainty in the quantification of prey biomass (i.e., energy flow between various ecosystem components). Trophic interactions in the deep sea are poorly known relative to coastal ecosystems due to an incomplete inventory of meso-and bathypelagic species composition. The CoML field project MAR-ECO has increased our knowledge of the faunal structure of the mid-North Atlantic. Deep-pelagic fish specimens from the 2004 MARECO expedition provided a basis for an …

Bathypelagic Fish Diversity In The Sargasso Sea, Northwestern Atlantic Ocean, Tracey Sutton, Peter Wiebe, Ann Bucklin, Laurence P. Madin

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

Of the various marine habitats, one of the (if not the) most daunting to quantify is the under-sampled bathypelagic zone (> 1000 m depth), which at 60% of the ocean’s volume is the largest habitat on Earth. One project addressing this challenge is the Census of

Marine Zooplankton (CMarZ), whose goal is the assessment of biodiversity of animal plankton throughout the world’s oceans. The 2006 CMarZ cruise in the Western North Atlantic provided an unprecedented opportunity to sample bathypelagic micronekton using a large midwater trawl (10-m2 MOCNESS) outfitted with fine (0.335-mm) mesh netting. This netting allowed non-destructive sampling of the …

The Importance Of Stealth: Recent Findings With The Eye-In-The-Sea Deep-Sea Observatory, Edith A. Widder, E. H. Raymond, Tracey Sutton

Marine & Environmental Sciences Faculty Proceedings, Presentations, Speeches, Lectures

The Eye-in-the-Sea (EITS) observatory was designed to be acoustically quiet and to use far-red illumination to observe deep-sea animals unobtrusively. The EITS has clearly demonstrated the critical importance of stealth in research ocean observatories. Its use has revealed both animals and behaviors never seen before. Additionally recordings of animal activity under different lighting conditions and in the presence or absence of different sound-producing vehicles (ROVs and submersibles) have revealed to what extent tools for exploration bias observations. Recent recordings made during a 2007 NOAA Ocean Exploration mission to deep waters around the Bahamas provide excellent additional examples of the importance …

The Adaptive Evolution Of The Mammalian Mitochondrial Genome, Rute R. Da Fonseca, Warren E. Johnson, Stephen J. O'Brien, Maria J. Ramos, Agostinho Antunes

Biology Faculty Articles

Background

The mitochondria produce up to 95% of a eukaryotic cell's energy through oxidative phosphorylation. The proteins involved in this vital process are under high functional constraints. However, metabolic requirements vary across species, potentially modifying selective pressures. We evaluate the adaptive evolution of 12 protein-coding mitochondrial genes in 41 placental mammalian species by assessing amino acid sequence variation and exploring the functional implications of observed variation in secondary and tertiary protein structures.

Results

Wide variation in the properties of amino acids were observed at functionally important regions of cytochrome b in species with more-specialized metabolic requirements (such as adaptation to …
