Vibrational Microspectroscopy For Cancer Screening, Fiona Lyng, Ines Ramos, Ola Ibrahim, Hugh Byrne

Articles

Vibrational spectroscopy analyses vibrations within a molecule and can be used to characterise a molecular structure. Raman spectroscopy is one of the vibrational spectroscopic techniques, in which incident radiation is used to induce vibrations in the molecules of a sample, and the scattered radiation may be used to characterise the sample in a rapid and non-destructive manner. Infrared (IR) spectroscopy is a complementary vibrational spectroscopic technique based on the absorption of IR radiation by the sample. Molecules absorb specific frequencies of the incident light which are characteristic of their structure. IR and Raman spectroscopy are sensitive to subtle biochemical changes …

Multivariate Statistical Methodologies Applied In Biomedical Raman Spectroscopy: Assessing The Validity Of Partial Least Squares Regression Using Simulated Model Datasets, Mark E. Keating, Haq Nawaz, Franck Bonnier, Hugh Byrne

Articles

Raman spectroscopy is fast becoming a valuable analytical tool in a number of biomedical scenarios, most notably disease diagnostics. Importantly, the technique has also shown increasing promise in the assessment of drug interactions on a cellular and subcellular level, particularly when coupled with multivariate statistical analysis. However, an important consideration, both with Raman spectroscopy and the associated statistical methodologies, is the accuracy of these techniques and more specifically the sensitivities which can be achieved and ultimately the limits of detection of the various methods. The purpose of this study is thus the construction of a model simulated data set with …

Social Transformation, Group Reputation, And Reputation Matching, Huan Wang, Yi Zhang

Research Collection School Of Economics

Unlike in small communities where one can strategically interact with another according to the latter’s individual reputation, players in complex societies often have to interact with strangers whose individual reputations cannot be easily acquired. They often have to infer their counterparts’ characteristics from the latters’ group reputation to simplify decision making. We provide a game theoretical model of reputation matching concerning corruption during social transformation. We show that the regime change from acquaintance matching to anonymous matching tends to cause rampant corruption and the effectiveness of anti-corruption policies is non-monotonic with respect to the supervision efforts.

Fertility And Rural Electrification In Bangladesh, Tomoki Fujii, Abu S. Shonchoy

Research Collection School Of Economics

We use a panel dataset from Bangladesh to examine the relationship between fertility and the adoption of electricity with the latter instrumented by infrastructure development and the quality of service delivery. We find that the adoption of electricity reduces fertility, and this impact is more pronounced when the household already has two or more children. This observation can be explained by a simple household model of time use, in which adoption of electricity affects only the optimal number of children but not necessarily current fertility behavior if the optimal number has not yet been reached.

Altared Object, Erin Jameson Brown

Theses

The thesis exhibition Altared Object seeks to undermine and expose the established religious and patriarchal practices that cause harm to women in contemporary society. In my art, I attempt to expose the latent sexist oppression that exists in society and in the church; how fundamental and foundational it is to our societal norms; and how this oppression is still widely accepted and adhered to, but not necessarily acknowledged today. Through the use of massproduced objects which I have purchased from thrift stores or found online, seemingly innocuous objects will be repurposed through a process of appropriation and reintroduced in a …

Assessment Of Serum Prolactin Level In Patients Women With Rheumatoid Arthritis, Rana S. Aboud

Baghdad Science Journal

The prolactin hormone played role in the many autoimmune disorders. To determine the importance of high levels of prolactin in triggering rheumatoid arthritis, thirty patient's women with hyperprolactinemia aged (20-45) years old have been investigated and compared with twenty five healthy individuals. All the studied groups were carried out to measure the concentration of citrulinated peptide(CCP) by enzyme linked immunosorbent assay( ELISA), antikeratin antibodies (AKA)and antinuclear antibodies(ANA) by indirect fluorescent assay IFAT. There was a significant elevation of CCP concentration compared with control groups (P< 0.05). The percentage of antikeratin antibodies and antinuclear antibodies was (20%, 10%) respectively, and there were significant differences (P< 0.05) between incidences percentage of antikeratin and antinuclear antibodies compared with control groups . This study indicated that women with rheumatoid arthritis may play a role as triggering factor of hyperprolactinemia

Observational Learning In The Jumping Spider Phidippus Audax, Robert M. Adams

School of Biological Sciences: Dissertations, Theses, and Student Research

Observational learning is a complex form of learning most frequently studied in social vertebrates. However, evidence for social learning exists in several invertebrate species Evidence of invertebrate observational learning also exists, though to a lesser extent. This study addresses observational learning in a jumping spider (Phidippus audax) through video playback. My results suggest that while observational learning is occurring, the exact mechanism in use remains unclear. Spiders that saw a conspecific satiate itself on a prey item readily attacked a similar prey item when exposed to a live prey item. However, spiders exposed to a conspecific rejecting or …

A Hybrid Cliff × Barn Swallow From Western Nebraska, Charles R. Brown, Catherine E. Page

Nebraska Bird Review

The Cliff Swallow (Petrochelidon pyrrhonota) and the Barn Swallow (Hirundo rustica) occupy sympatric breeding ranges across much of North America, often nesting at colony sites that contain both species. Mixed-species nesting aggregations typically occur in box-shaped concrete culverts underneath roads or railways. Cliff Swallows’ enclosed mud nests can be as close as 1 m to Barn Swallows’ open mud nests, and at such sites Cliff Swallows regularly usurp both inactive and active Barn Swallow nests. The close proximity of these two ecologically similar species leads to at least occasional social interaction among them, such as during …

Environmental Microbes And Uveitis: Is Microbial Exposure Always Bad?, Chandirasegaran Massilamany, A. Gangaplara, J. Reddy

School of Veterinary and Biomedical Sciences: Faculty Publications

The eye generally is considered to be an immune-privileged organ, but this notion is being increasingly challenged as ocular antigens can be expressed in the generative lymphoid organs, resulting in attainment of self-tolerance. What triggers a break in this tolerant state is a fundamental question in autoimmunity research. The general belief is that exposure to environmental microbes can break self-tolerance in genetically susceptible individuals, leading to the induction of autoimmune responses. The molecular mimicry hypothesis has been proposed as one major mechanistic, pathway through which microbes, by generating crossreactive immune responses, can induce ocular damage of the kind that might …

Stress And Eyewitness Memory: Timing Of Stressor And Association With Cortisol Stress Responding, Timothy Ryan Robicheaux

Department of Psychology: Dissertations, Theses, and Student Research

Witnesses to and victims of criminal events can face significant stress during such encounters. Stress responding consists of a multitude of responses (e.g., anxiety, cardiovascular changes, cortisol responding). In the current study, I utilized a physiological stressor (i.e., the cold-pressor test) and a facial recognition paradigm to examine the relationship between cortisol change following stress exposure and memory accuracy. More specifically, I examined whether cortisol levels at specific memory stages (i.e., acquisition and retrieval) predicted stress responding differently.

Findings suggested that individual differences in cortisol stress responding to the cold-pressor test predicted facial recognition when peak cortisol was at a …

Department of Earth and Atmospheric Sciences: Faculty Publications

The Southeast Asian mainland is located in the central path of the Asian summer monsoon, a region where paleoclimatic data are still sparse. Here we present a multi-proxy (TOC, C/N, δ13C, biogenic silica, and XRF elemental data) study of a 1.5 m sediment/peat sequence from Lake Pa Kho, northeast Thailand, which is supported by 20 AMS 14C ages. Hydroclimatic reconstructions for Pa Kho suggest a strengthened summer monsoon between BC 170–AD 370, AD 800–960, and after AD 1450; and a weakening of the summer monsoon between AD 370–800, and AD 1300–1450. Increased run-off and a higher nutrient supply after AD …

Mortality Patterns Among Critically Ill Children In A Pediatric Intensive Care Unit Of A Developing Country, Naveed-Ur-Rehman Siddiqui, Zohaib Ashraf, Humaira Jurair, Anwarul Haque

Department of Paediatrics and Child Health

Background and Aim: Advances in biomedical technology have made medical treatment to be continued beyond a point, at which it does not confer an advantage but may increase the suffering of patients. In such cases, continuation of care may not always be useful, and this has given rise to the concept of limitation of life-sustaining treatment. Our aim was to study mortality patterns over a 6-year period in a Pediatric Intensive Care Unit (PICU) in a developing country and to compare the results with published data from other countries.
Materials and Methods: Retrospective cohort study was conducted in a PICU …

Long-Term Changes In Seasonal Fish Assemblage Dynamics In An Adventitious Desert Stream, Seiji Miyazono, Christopher M. Taylor

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Tornillo Creek, a tributary of the Rio Grande in Texas, United States, has historically been an important nursery and spawning habitat for several native fish species. We examined variation in the seasonal fish assemblages in Tornillo Creek within and between two time periods (1967–1970 vs. 2009–2011), and contemporary fish assemblage–environment associations, in order to understand what environmental factors were associated with seasonal fish abundance and occupancy patterns. Our results indicated that fish assemblages were very different between the two time periods. Contemporary seasonal fish assemblage patterns in Tornillo Creek were less variable than historical assemblages and were linked to several …

School of Integrative Biological & Chemical Sciences (Formerly Dept. of Biology)

Annual outbreaks of green peach aphid, Myzus persicae (Sulzer), limit commercial production of brassica crops, especially in organic systems in subtropical areas such as South Texas. We assessed the influence of companion plants that emit attractant, repellent, and natural enemy-attractant stimuli (i.e., insectary plants) on abundance of green peach aphid in organic kale (Brassica oleracaea L. var. acephala) fields in South Texas. We also monitored the assemblage of arthropod predators and parasitoids on kale and evaluated the response of numerically dominant species to companion plants. Indian mustard (Brassica juncea (L.) Vassiliĭ Matveievitch Czernajew; attractant), dill (Anethum graveolens L.; repellent), fennel …
