Salmonellosis continues to be an important health concern in the United States and throughout the world.  Salmonella is a genus of rod-shaped, Gram-negative, non-spore forming, predominantly motile enterobacteria.  Some pathogenic species commonly grow in the intestines of chickens and other warm blooded animals, including humans.  Several factors allowing Salmonella to colonize the intestines of chickens have been identified, such as type 1 fimbriae (hair like projections that surround the cell).  To this end, we have devised a genetic strategy to iden

On April 20th 2010, the Deep Water Horizon Well in the Gulf of Mexico exploded.  Resulting is the worst environmental disaster in the United States' history.  The environmental impacts are wide reaching but for my research I focused on the salt marshes in Louisiana.

Individuals with damage to the hippocampus show marked memory impairments for learning new declarative information in everyday life and on standardized memory tests. However, previous work by Duff and colleagues (2006) has shown that participants with hippocampal amnesia display robust learning for labels used to describe twelve abstract Chinese tangrams in a Barrier Task setting.

It was recently found that one ECF sigma factor, SigV, in Bacillus subtilis is induced by lysozyme stress. Activity of SigV is inhibited by a membrane bound anti-sigma factor RsiV. Many ECF sigma factors are activated by two successive proteolytic events known as site 1 and site 2 cleavage of the anti-sigma factor in response to antimicrobial peptides and other agents that damage the cell envelope. These two sites are cleaved by specific proteases that function to destroy the anti-sigma factor.

OBJECTIVE. Patent ductus arteriosus is a congenital heart defect that leads to abnormal blood flow between the aorta and the pulmonary artery. The incidence of patent ductus arteriosus increases with decreasing gestational age where up to 76.9% of preterm infants are born at 24 weeks gestation. Our goal was to determine if genetic risk factors play a role in patent ductus arteriosus. METHODOLOGY.

Multiple Myeloma is a malignant plasma cell proliferative disorder. Plasma cells are white blood cells that produce large volume of antibodies and they are originating in the lymphatic tissue. Multiple myeloma is incurable with existing therapies. Chemotherapeutic drugs and radiation therapy provide some benefit but all patients relapse with fatal outcome. It is therefore very important to understand how best to eliminate the tumor cells in their normal microenvironment. Malignant cells, in general, are under oxidative stress due to their aberrant metabolic regulations.

This research study sought to determine whether previous findings regarding the effect of diversity on in-group and out-group trust were influenced by social desirability bias. It also sought to uncover the role of community diversity on interpretations of questions on trust, as another potential explanation for the often-reported negative relationship between community diversity and generalized trust.

A challenge with stem cell therapy is identifying where the injected cells will travel; one potential solution is the use of fluorescent biomarkers. In vivo they would give their target a fluorescent color which can be identified using a microscope equipped with a fluorescent filter, this would allow researchers to see if the cells have reached the targeted area, from there they will be able to modify the procedure, making it more effective. Fluorescein isothiocyanate or (FITC) has proven to be a potential biomarker because of its low toxicity [1].

A classic problem in speech perception is the information listeners use to distinguish words.  This must be solved by every child over development as they determine constellation of acoustic cues used by their language. Classic approaches posit that people learn to perceive individual sounds first and then assemble them to acquire words. We asked the converse question: does learning words help acquire individual sounds, more specifically whether learning highly similar words improves speech perception.

Existing research on the achievement gap between Whites and minorities has suggested that the underachievement of minority students can be partially attributed to the psychologically threatening stereotype threat which is the fear of confirming or being evaluated by negative stereotypes (Steele, 1995). The related theory of differential expected consequences (Lovaglia, 2004) proposes that minority students also anticipate a variety of negative consequences to ensue for academic performance that is lower or higher than expected.

The compendium of existing research that focuses on the gap in achievement between White and minority students has supplied compelling psychosocial explanations with empirical support.  Stereotype threat, the disruptive concern of confirming or being evaluated by a negative stereotype (Steele, 1997), has been extensively investigated as a factor that undermines the academic performance of stigmatized minorities.  The related theory of differential expected consequences (Lovaglia, 2004) proposes that minority students expect variegated aversive consequences for academic performance

The purpose of this research was to examine whether, and if so, how mainstream American perceptions of Black men have changed between the years 1950 and 2010. I hypothesized that although progress has been made in positively portraying some affluent Black men, the majority of American society appears to still cling to negative stereotypes and images of Black men created prior to 1950, primarily surrounding slavery.

Emotion, feelings and mood are fundamental factors driving human behavior. Very little is known about whether there are racial differences in response to film-induced emotional stimuli and virtually nothing is known about their psychophysiological manifestations. One's threshold for stress is due in large part to how they process emotion. There are ethnic differences in cardiovascular arousal during stressful situations. In comparison to Caucasians, African Americans encounter higher resting levels of blood pressure, blood pressure reactivity, and mortality from hypertension.

"Physical activity is defined as any bodily movement produced by skeletal muscles that require energy expenditure" World Health Organization, 2010).  Many people benefit by having healthier lifestyles if they increase their physical activity (http://www.nlm.nih.gov/, 2010).  When many individuals think about physical activity, exercise or structured activity may come to mind.  If exercise is coming to mind, it is hard to be physically active if there is no place to exercise or participate in planned physical activity.  If people defi
