E,E-Farnesol Inhibits Swarming Motility In Burkholderia Cepacia Through Rhamnolipid Production, Stephanie E. Nicholls, Alayna N. Sanderson, Andrea P. Schwartz, Lauren E. Ward, Jessica N. Weisensee, Molly Yandrofski, Tracy L. Collins
The Research and Scholarship Symposium
Burkholderia cepacia and Candida albicans both exhibit cell-to-cell communication through the use of quorum-sensing molecules (QSM) known as autoinducers. E,E-farnesol is a QSM produced by C. albicans which regulates its conversion from yeast to mycelium. Because there is a positive correlation between the presence of B. cepacia and C. albicans in the lungs of individuals with cystic fibrosis (CF), we examined whether E,E-farnesol had an effect on swarming motility in B. cepacia. Swarming motility was inhibited when B. cepacia was exposed to 250 µM of E,E-farnesol. In addition, there was a 26.8% decrease in rhamnolipid production ...
The Effect Of Photoactivated Tmp On Burkholderia Cepacia Biofilms, 2017 Cedarville University
The Effect Of Photoactivated Tmp On Burkholderia Cepacia Biofilms, Reyna G. Osorio, Chandra N. Swiech, Tracy L. Collins
The Research and Scholarship Symposium
Burkholderia cepacia is an opportunistic pathogen that causes infections in immunocompromised individuals such as cystic fibrosis patients. B. cepacia infections are typically characterized by the formation of complex communities of cells known as biofilms. Because B. cepacia biofilms are difficult to eradicate using antibiotics, it is important to pursue alternative treatment methods. Photodynamic therapy (PDT) is a type of therapy that uses light, a photosensitizer, and oxygen to elicit cell death through the production of reactive oxygen species. PDT has been shown in previous studies to be successful in killing both Pseudomonas aeruginosa and Staphylococcus aureus. In this study, we ...
Therapeutic Application Of Carbon Monoxide In Acute Limb Compartment Syndrome, 2017 The University of Western Ontario
Therapeutic Application Of Carbon Monoxide In Acute Limb Compartment Syndrome, Aurelia Bihari
Electronic Thesis and Dissertation Repository
Acute limb compartment syndrome (CS), a devastating complication of musculoskeletal trauma, develops in response to elevation of the pressure within a closed osseofascial compartment, producing muscle- and limb-threatening ischemia. Full decompression of all involved compartments by fasciotomy is the current gold-standard therapy, but it must be performed within a surgical window of 6-8 hours, before tissue damage becomes permanent.
Carbon monoxide (CO), a byproduct of heme metabolism, has been shown protective in ischemia. While inhalation of CO leads to elevation of carboxyhemoglobin (COHb), recent development of transitional metal carbonyls, CO-releasing molecules (CO-RMs), particularly the water-soluble CORM-3, delivers CO in a ...

Docking Studies Of Isoform-Selectivity Of Phosphatidylinositol 3-Kinase (Pi3k) Inhibitors, Kaitlin Goettsch
Student Research and Creative Activity Fair
Phosphatidylinositol 3-kinases (PI3Ks) and their related pathways are reputed targets for drug-based anticancer therapies. Mutations in PI3K genes, expression, and pathways are frequent among multiple cancer types. Four isoforms of PI3Ks exist: α, β, γ, & δ and studies have identified several ligands for each isoform which are capable of serving as inhibitory therapeutic compounds. However, the biochemical efficacy of these molecules varies and the isoform selectivity is not well understood. In this study, we applied in silico docking methods and free energy calculation methods to estimate the binding of reported PI3K ligands against 5 PI3K structures: PI3Kα (PBD ID: 2RD0 ...

Library Articles and Research
Synovial sarcoma (SS) is an aggressive soft tissue sarcoma (STS) that typically occurs in the extremities near a joint. Metastatic disease is common and usually occurs in the lungs and lymph nodes. Surgical management is the mainstay of treatment with chemotherapy and radiation typically used as adjuvant treatment. Although chemotherapy has a positive impact on survival, the prognosis is poor if metastatic disease occurs. The biology of sarcoma invasion and metastasis remain poorly understood. Chromosomal translocation with fusion of the SYT and SSX genes has been described and is currently used as a diagnostic marker, although the full impact of ...

The Effects Of Apigenin On Cell Proliferation And Apoptosis In Glioblastoma Multiforme, Trevor Stump, Brittany Santee, Lauren Williams, Chelsae Heinze, Rachel Kunze, Samson Amos, Denise S. Simpson
Samson Amos, R.Ph., Ph.D.
Glioblastoma multiforme (GBM) is a WHO grade IV brain tumor. These tumors are highly proliferative, infiltrative, necrotic, angiogenic, and resistant to apoptosis. One major characteristic of GBM is the overexpression of epidermal growth factor receptor (EGFR), which leads to cell growth and proliferation when activated. GBM is very difficult to treat due to its location, heterogeneity, and invasiveness; an effective treatment is therefore needed. The use of flavonoids, which are natural compounds found in many fruits and vegetables, has been studied in the treatment of many different tumor types. Apigenin is a specific flavonoid that has previously been shown to ...

Electronic Theses and Dissertations
Sexually transmitted infections affect hundreds of millions of worldwide. Both human immunodeficiency virus (HIV-1 and -2) and herpes simplex virus-2 (HSV-2) remain incurable, urging the development of new prevention strategies. While current prophylactic technologies are dependent on strict user adherence to achieve efficacy, there is a dearth of delivery vehicles that provide discreet and convenient administration, combined with prolonged-delivery of active agents. To address these needs, we created electrospun fibers (EFs) comprised of FDA-approved polymers, poly(lactic-co-glycolic acid) (PLGA) and poly(DL-lactide-co-ε-caprolactone) (PLCL), to provide sustained-release and in vitro protection against HIV-1 and HSV-2. PLGA and PLCL EFs, incorporating the ...

Effects Of Prenatal Exposure To Bisphenol A On Fetal Lung Development, Ayten Hijazi
Electronic Thesis and Dissertation Repository
Prenatal exposure to bisphenol A (BPA), one of the most prevalent endocrine disrupting chemicals, is associated with lung dysfunction and diseases in later life. However, it is unknown if this association has a fetal origin. In this thesis, a series of in vivo and in vitro experiments were conducted to determine the effects of prenatal exposure to BPA on fetal lung development, and define the underlying molecular mechanisms. Environmentally relevant doses of BPA were administered to pregnant mice via diet from embryonic day (E) 7.5 to 18.5. Fetal lungs were analyzed at E18.5 for changes in structure ...

Light-Enhanced Startle As An Experimental Model Of Withdrawal, 2016 College of William and Mary
Light-Enhanced Startle As An Experimental Model Of Withdrawal, Augustin C. Hennings
Undergraduate Honors Theses
Nicotine is extremely addictive, and the negative effects of withdrawal, such as increased anxiety, contribute to relapse. Nicotine produces significant changes in the extended amygdala, the brain regions responsible for regulating anxiety. Light-Enhanced Startle is an established method for assessing anxiety in animal models and is sensitive to drug manipulations. This thesis had two goals, Experiment 1 asked: can LES be used to investigate the anxiety of extended nicotine withdrawal following chronic nicotine administration in rats? We hypothesized that exposing rats to chronic nicotine would result in elevated LES during spontaneous withdrawal as compared to controls, and that this elevation ...
Studies On The Prevalence And Control Of Parasitic Helminths In "Natural" Laying Hens, 2016 University of Arkansas, Fayetteville
Studies On The Prevalence And Control Of Parasitic Helminths In "Natural" Laying Hens, Brittany R. Weir
Animal Science Undergraduate Honors Theses
One societal trend that has been gaining much traction and popularity since the 21st century began is “organic” and/or “natural” food products. In 1999, the global market accounted for $15.2 billion dollars worth of organic food and drink, compared to the market in 2014 where we consumed $80 billion dollars worth (Willer et. al, 2016). With “natural” production of food animals however, “natural” parasite transmission may be a consequence. To that end, this experiment examines the prevalence of helminths in 110 “natural” laying hens from three regional farms and the efficacies of fenbendazole, piperazine, and levamisole on ...
