The Use Of Geospatial Modeling And Novel Diagnostics To Detect And Map Risk Factors Of Soil-Transmitted Helminths In Feira De Santana, Brazil, Ryan Harry Avery

LSU Doctoral Dissertations

Soil-transmitted helminth (STH) infections impact billions of people worldwide. The traditional STH control approach is a morbidity control strategy implementing mass drug administration (MDA) programs targeting school-aged children (SAC). In Brazil, this control strategy has decreased STH prevalence to less than 20% in most of the country and providing an opportunity to transition from the morbidity control program and towards a surveillance and response system geared towards STH elimination. Surveillance and response systems geared towards elimination require the implementation higher accuracy diagnostics to detect infection in low-transmission communities, surveillance of entire households, high-resolution modeling at the household-habitat scale, and targeted …

Local Electronic Structure Of The Peptide Bond Probed By Resonant Inelastic Soft X-Ray Scattering, L. Weinhardt, A. Benkert, F. Meyer, M. Blum, D. Hauschild, R. G. Wilks, M. Bär, W. Yang, M. Zharnikov, F. Reinert, C. Heske

Chemistry and Biochemistry Faculty Research

The local valence orbital structure of solid glycine, diglycine, and triglycine is studied using soft X-ray emission spectroscopy (XES), resonant inelastic soft X-ray scattering (RIXS) maps, and spectra calculations based on density-functional theory. Using a building block approach, the contributions of the different functional groups of the peptides are separated. Cuts through the RIXS maps furthermore allow monitoring selective excitations of the amino and peptide functional units, leading to a modification of the currently established assignment of spectral contributions. The results thus paint a new-and-improved picture of the peptide bond, enhance the understanding of larger molecules with peptide bonds, and …

Laryngeal Preservation Strategies In Locally Advanced Laryngeal And Hypopharyngeal Cancers., Athanassios Argiris, Jean Louis Lefebvre

Department of Medical Oncology Faculty Papers

For long, the treatment of locoregionally advanced laryngeal and hypopharyngeal squamous cell cancers (SCC) consisted of either total laryngectomy (TL) or definitive radiotherapy (RT). The development of induction cisplatin plus 5-fluorouracil (PF) and the correlation between chemosensitivity and radiosensitivity in previously untreated patients opened a new era of treatment aiming at laryngeal preservation (LP). The fundamental concept was to employ induction PF in order to select patients for subsequent treatment with either TL or RT according to tumor response to PF. The first two trials (VALGSG for laryngeal SCC and EORTC 24891 for hypopharyngeal SCC) concluded that such an approach …

Second-Harmonic Generation Microscopy Analysis Reveals Proteoglycan Decorin Is Necessary For Proper Collagen Organization In Prostate., Kirby R. Campbell, Rajeev Chaudhary, Monica Montano, Renato V. Iozzo, Wade A. Bushman, Paul J. Campagnola

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Collagen remodeling occurs in many prostate pathologies; however, the underlying structural architecture in both normal and diseased prostatic tissues is largely unexplored. Here, we use second-harmonic generation (SHG) microscopy to specifically probe the role of the proteoglycan decorin (Dcn) on collagen assembly in a wild type (wt) and Dcn null mouse (Dcn  -    /    -  ). Dcn is required for proper organization of collagen fibrils as it regulates size by forming an arch-like structure at the end of the fibril. We have utilized SHG metrics based on emission directionality (forward-backward ratio) and relative conversion efficiency, which are both related to …

The Effect Of Caregiver Burnout On Alzheimer's Treatment Compliance, Daniel Kane, Brandon Liu May 2019

The Effect Of Caregiver Burnout On Alzheimer's Treatment Compliance, Daniel Kane, Brandon Liu

School of Psychology, Family, and Community Research Conference

According to the Alzheimer's Association (2019), approximately 5.8 million Americans live with Alzheimer's Disease (AD). Additionally, it is reported that 16 million Americans are considered caregivers to those individuals. While AD is incurable, treatment adherence is a significant predictor of family and patient outcomes. This proposal explores the impact of caregiver burnout on patient treatment compliance of those with Alzheimer's disease (AD). It is hypothesized that the presence of burnout in caregivers of loved ones with AD will negatively affect treatment compliance. A possible implication of this study is improving quality of life outcomes for those managing AD.

Gender Differences In Non-Suicidal Self-Injury In A Sample Of Treatment-Seeking Gamblers, Megan Cowie May 2019

Gender Differences In Non-Suicidal Self-Injury In A Sample Of Treatment-Seeking Gamblers, Megan Cowie

International Conference on Gambling & Risk Taking

Gambling Disorder (GD) is a public health concern with tremendous implications (Smith & Wynne, 2002). The disorder rarely occurs in isolation, often presenting with other conditions. Suicidal ideation and attempts are common among treatment-seeking gamblers (Maccallum & Blaszczynski, 2003). An important yet overlooked risk factor for suicidality is non-suicidal self-injury (NSSI; Klonsky et al., 2013). NSSI can serve many functions: relief of negative emotions; generation of positive states; escape from interpersonal obligations; attention or facilitation of resources (Nock & Prinstein, 2004). Previous research has found gender differences in NSSI. Despite NSSI’s relationship to suicidality and the noted gender differences, literature …

An Overview Of American Ginseng Through The Lens Of Healing, Conservation And Trade, Margaret Wulfsberg May 2019

An Overview Of American Ginseng Through The Lens Of Healing, Conservation And Trade, Margaret Wulfsberg

Lawrence University Honors Projects

American ginseng (Panax quinquefolius) is an herbaceous plant found in the eastern United States and Canada. Due to the high demand for ginseng roots on the Chinese market, it has been harvested at unsustainable rates. If this continues, overharvest along with other environmental factors will lead it to become extinct in the wild. American ginseng became popular due to its similarities with Asian ginseng, (Panax ginseng), a related plant that has been used in Chinese medicine for hundreds of years. Since there is so little Asian ginseng left in the wild, American ginseng now helps satisfy …

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano May 2019

Technical Freediving: An Emerging Breath-Hold Diving Technique, Derek Covington, Robert H. Lee, Steven Toffel, Alberto Bursian, Kirk Krack, Chris Giordano

Journal of Human Performance in Extreme Environments

Technical freediving can be defined as freediving augmented by the use of oxygen-enriched gases or oxygen before, during, or after a freedive. As a result of these techniques, breath-hold divers can visit and enjoy underwater wrecks, reefs, and other diving locations previously located at depths unreachable to apnea divers. By pre-breathing oxygen-enriched gases in conjunction with hyperventilation—which decreases the partial pressure of carbon dioxide (PCO2)—the technical freediver now has additional oxygen to facilitate aerobic respiration during the dive. In addition, pre-breathing oxygen decreases tissue nitrogen tensions, which limits inert gas loading and decreases the risk of decompression sickness (DCS). Finally, …
