The purpose of the study was to determine the specific periods during pregnancy in which human fetal exposure to stress hormones affects newborn physical and neuromuscular maturation. Blood was collected from 158 women at 15, 19, 25, and 31 weeks' gestation. Levels of placental corticotropin-releasing hormone (CRH) and maternal cortisol were determined from plasma. Newborns were evaluated with the New Ballard Maturation Score. Results indicated that increases in maternal cortisol at 15, 19, and 25 weeks and increases in placental CRH at 31 weeks were significantly associated with decreases in infant maturation among mates (even after con trolling for length …

Psychology Faculty Articles and Research
OBJECTIVE: To extend findings that African American women report greater stress during pregnancy, have higher blood pressure (BP), and are twice as likely to have low birthweight infants relative to white women. This study examines a) racial differences in associations between stress and BP during pregnancy, and b) the combined effects of stress and BP on infant birthweight in a sample of 170 African American and white women.
METHODS: A prospective, longitudinal study of pregnant women was conducted in which measures of BP, stress, and other relevant variables were collected. Multiple measures of systolic and diastolic BP were taken at …
The Evaluation Of Midazolam On Head Injured Patients In The Prehospital Setting, Dragana Klinac
The Evaluation Of Midazolam On Head Injured Patients In The Prehospital Setting, Dragana Klinac
Theses: Doctorates and Masters
Midazolam (Hypnovel ®) is the only sedating agent used by paramedics at St John Ambulance Service W.A. in the management of many conditions including seizure activities, antisocial or uncontrollable behaviours, back pain incidents and head injuries. Midazolam, with a rapid absorption, fast onset of action and short duration on neurological activity, has been accepted as a safe and effective agent in prehospital treatment since the late-1990s. Often, if a patient is not complying with treatment or is uncontrollable or aggressive, paramedics are required to sedate the individual. This study primarily examines the use of midazolam for the sedation of unmanageable …

Purpose: Platelet-derived growth factor (PDGF) is associated with corneal fibroblast migration and proliferation and plays an important role in corneal wound healing. However, the intracellular mechanisms of PDGF-mediated functions in corneal fibroblasts are poorly understood. We tested the hypothesis that PDGF functional activities in the cornea involve the Janus kinase-2/signal transducers and activators of transcription-3 (JAK2-STAT3) signaling pathway and whether PDGF induces the expression of suppressors of cytokine signaling 3 (SOCS3), belonging to the novel family of feedback regulators of cytokine and growth factor activities.
Methods: Human corneal fibroblast (HSF) cultures were used as an in vitro model for functional …
Determining Standard Criteria For Endotracheal Suctioning In The Paediatric Intensive Care Patient: An Exploratory Study [Thesis], Kylie Davies
Theses: Doctorates and Masters
Endotracheal tube (ETT) suction is a common nursing procedure within the paediatric intensive care (PIC) setting. Significant side effects associated with this procedure can dramatically affect the stability of the critically ill ventilated paediatric patient. A comprehensive literature review failed to establish clear standards for determining when the procedure is warranted, especially in the paediatric population. This can present difficulty for the inexperienced paediatric intensive care nurse when assessing a patient's need for ETT suction. The aim of the research was to design an evidence based endotracheal suction assessment tool (ESAT) for use by nurses caring for paediatric patients. The …

Evaluation Of Suspected Renal Colic Patients With Unenhanced Low-Dose Multidetector Computed Tomography (Mdct), Nebayosi Twahirwa
Theses & Dissertations
Acute renal colic is probably one of the most excruciatingly painful event a person can endure. [1]. Though this is typical of urinary tract calculi, it’s important to note that non-calculus and non-genitourinary conditions can present in a similar manner. Unenhanced helical CT (CT KUB), originally described by Smith et al [2] in 1995, is one single radiological test that has proven successful in the valuation of patients presenting with renal colic. This technique has been shown to be more accurate compared to abdominal radiography [3,4], ultrasound and has replaced excretory urography in the detection of urinary tract calculi in …

In vivo induced antigen technology (IVIAT) is an immuno-screening technique that identifies bacterial antigens expressed during infection and not during standard in vitro culturing conditions. We applied IVIAT to Bacillus anthracis and identified PagA, seven members of a N-acetylmuramoyl-L-alanine amidase autolysin family, three P60 family lipoproteins, two transporters, spore cortex lytic protein SleB, a penicillin binding protein, a putative prophage holin, respiratory nitrate reductase NarG, and three proteins of unknown function. Using quantitative real-time PCR comparing RNA isolated from in vitro cultured B. anthracis to RNA isolated from BALB/c mice infected with virulent Ames strain B. anthracis, we confirmed induced …

BACKGROUND: Enterococcus faecalis has emerged as a major hospital pathogen. To explore its diversity, we sequenced E. faecalis strain OG1RF, which is commonly used for molecular manipulation and virulence studies.
RESULTS: The 2,739,625 base pair chromosome of OG1RF was found to contain approximately 232 kilobases unique to this strain compared to V583, the only publicly available sequenced strain. Almost no mobile genetic elements were found in OG1RF. The 64 areas of divergence were classified into three categories. First, OG1RF carries 39 unique regions, including 2 CRISPR loci and a new WxL locus. Second, we found nine replacements where a sequence …
The Effect Of Nurse Initiated Paracetamol On Emergency Department Patients With Pain From Low Acuity Injury, Joanne G. Wilson
The Effect Of Nurse Initiated Paracetamol On Emergency Department Patients With Pain From Low Acuity Injury, Joanne G. Wilson
Theses: Doctorates and Masters
Early identification and management of pain was identified at the commencement of this study as a key area requiring research in emergency departments. Prolonged waiting times for analgesia especially, was highlighted in the National Institute of Clinical Studies emergency department collaborative in 2003. Many barriers exist for a patient to receive analgesia. In Western Australia this is compounded by the legislation which restricts prescribing rights for nurses. Three considerations guided the development of the research project. Firstly, the patient has initial contact with the emergency department from the nurse at triage. Secondly, paracetamol was recognised as a potentially effective analgesic …
Understanding The Relationship Between The Diligence Inventory-Higher Education Edition And The Myers-Briggs Type Indicator In The Admission Of College Students To An Orthopaedics-Based Honors Program, Michael A. Harstine
Dissertations
Problem. The Orthopaedic Scholar Institute (OSI) Team realized its need for a more objective selection and admission process that, as much as possible, quantified the characteristics desired in OSI students rather than relying solely on referral perception, intuition, and an interview, but it did not have a clear method or approach to do so. Administering standardized inventories that highlighted these desired characteristics and aided in the selection and admission process seemed to be an objective approach to obtain more quantifiable data. The problem for my study was, therefore, whether the Myers- Briggs Type Inventory (MBTI) alone could measure a student’s …

Journal Articles
Congestive heart failure has long been one of the most serious medical conditions in the United States; in fact, in the United States alone, heart failure accounts for 6.5 million days of hospitalization each year. One important goal of heart-failure therapy is to inhibit the progression of congestive heart failure through pharmacologic and device-based therapies. Therefore, there have been efforts to develop device-based therapies aimed at improving cardiac reserve and optimizing pump function to meet metabolic requirements. The course of congestive heart failure is often worsened by other conditions, including new-onset arrhythmias, ischemia and infarction, valvulopathy, decompensation, end-organ damage, and …

The recognition of the importance of mRNA turnover in regulating eukaryotic gene expression has mandated the development of reliable, rigorous, and "user-friendly" methods to accurately measure changes in mRNA stability in mammalian cells. Frequently, mRNA stability is studied indirectly by analyzing the steady-state level of mRNA in the cytoplasm; in this case, changes in mRNA abundance are assumed to reflect only mRNA degradation, an assumption that is not always correct. Although direct measurements of mRNA decay rate can be performed with kinetic labeling techniques and transcriptional inhibitors, these techniques often introduce significant changes in cell physiology. Furthermore, many critical mechanistic …

Since its inception in the late nineteenth century, the juvenile court has been concerned with the legal problems of children and their families. From the court’s earliest days, it has sought to address child abuse and neglect and juvenile delinquency as social problems that result from familial and community breakdown. Over the decades, researchers from various disciplines have provided varying explanations of how and why family systems break down, why some parents fail to nurture their children, why some physically or sexually abuse their children, and why some children become delinquent.
The Role Of Peroxisome Proliferator-Activated Receptors In The Development And Physiology Of Gametes And Preimplantation Embryos, Jaou-Chen Huang
The Role Of Peroxisome Proliferator-Activated Receptors In The Development And Physiology Of Gametes And Preimplantation Embryos, Jaou-Chen Huang
Journal Articles
In several species, a family of nuclear receptors, the peroxisome proliferator-activated receptors (PPARs) composed of three isotypes, is expressed in somatic cells and germ cells of the ovary as well as the testis. Invalidation of these receptors in mice or stimulation of these receptors in vivo or in vitro showed that each receptor has physiological roles in the gamete maturation or the embryo development. In addition, synthetic PPAR gamma ligands are recently used to induce ovulation in women with polycystic ovary disease. These results reveal the positive actions of PPAR in reproduction. On the other hand, xenobiotics molecules (in herbicides, …

The authors test single nucleotide polymorphisms (SNPs) in coding sequences of 12 candidate genes involved in glucose metabolism and obesity for associations with spina bifida. Genotyping was performed on 507 children with spina bifida and their parents plus anonymous control DNAs from Hispanic and Caucasian individuals. The transmission disequilibrium test was performed to test for genetic associations between transmission of alleles and spina bifida in the offspring (P < .05). A statistically significant association between Lys481 of HK1 (G allele), Arg109Lys of LEPR (G allele), and Pro196 of GLUT1 (A allele) was found ( P = .019, .039, and .040, respectively). Three SNPs on 3 genes involved with glucose metabolism and obesity may be associated with increased susceptibility to spina bifida.

Diseases are believed to arise from dysregulation of biological systems (pathways) perturbed by environmental triggers. Biological systems as a whole are not just the sum of their components, rather ever-changing, complex and dynamic systems over time in response to internal and external perturbation. In the past, biologists have mainly focused on studying either functions of isolated genes or steady-states of small biological pathways. However, it is systems dynamics that play an essential role in giving rise to cellular function/dysfunction which cause diseases, such as growth, differentiation, division and apoptosis. Biological phenomena of the entire organism are not only determined by …

Maldi Mass Spectrometry Imaging For The Discovery Of Prostate Carcinoma Biomarkers, Lisa Harris Cazares
Theses and Dissertations in Biomedical Sciences
The elucidation of new biological markers of prostate cancer (PCa) should aid in the detection, and prognosis of this disease. Diagnostic decision making by pathologists in prostate cancer is highly dependent on tissue morphology. The ability to localize disease-specific molecular changes in tissue would help improve this critical pathology decision making process. Direct profiling of proteins in tissue sections using MALDI imaging mass spectrometry (MALDI-IMS) has the power to link molecular detail to morphological and pathological changes, enhancing the ability to identify candidates for new specific biomarkers. However, critical questions remain regarding the integration of this technique with clinical decision …

INTRODUCTION: Hemophagocytic lymphohistiocytosis is an immune-mediated syndrome that typically has a rapidly progressive course that can result in pancytopenia, coagulopathy, multi-system organ failure and death. CASE PRESENTATION: A 57-year-old Caucasian woman was referred in fulminant hemophagocytic lymphohistiocytosis, with fever, pancytopenia, splenomegaly, mental status changes and respiratory failure. She was found to have stage IV classical Hodgkin lymphoma, in addition to Epstein-Barr virus and cytomegalovirus viremia. Her presentation was preceded by a 3-year prodrome consisting of cytopenia and fever that were partially controlled by steroids and azathioprine. CONCLUSION: Fulminant hemophagocytic lymphohistiocytosis may follow a prodromal phase that possesses features suggestive of …

Noninvasive serial monitoring of the fate of transplanted cells would be invaluable to evaluate the potential therapeutic use of human hepatocyte transplantation. Therefore, we assessed the feasibility of bioluminescent imaging using double or triple fusion lentiviral vectors in a NOD-SCID mouse model transplanted with immortalized human fetal hepatocytes. Lentiviral vectors driven by the CMV promoter were constructed carrying reporter genes: firefly luciferase and green fluorescence protein with or without herpes simplex virus type 1 thymidine kinase. Human fetal hepatocytes immortalized by telomerase reconstitution (FH-hTERT) were successfully transduced with either of these fusion vectors. Two million stably transduced cells selected by …

Childhood Sexual Abuse In Black Men Who Have Sex With Men: Results From Three Qualitative Studies, Sheldon D. Fields, David J. Malebranche, Sonja Feist-Price
David J Malebranche
This report describes the high prevalence and context of childhood sexual abuse (CSA) among Black men who have sex with men (MSM) across 3 independent qualitative studies. Semistructured one-on-one interviews were conducted with 87 Black MSM across 3 cities (Rochester, NY, n=28; Lexington, KY/Atlanta, GA, n=30; and Atlanta, GA, n =29). A combined CSA prevalence of 32% (28/87) was found among the 3 samples, despite variation in geographic location, mean age, and sexual identification. Common themes emerging across the 3 samples included prolonged and repeated abuse by a close male relative; blaming of same-sex desire on CSA; and descriptions of …

Bisexually Active Black Men In The United States And Hiv: Acknowledging More Than The "Down Low", David J. Malebranche
David J Malebranche
HIV is disproportionately impacting Black men who have sex with men and heterosexual women in theUnited States. Current speculation posits a ‘‘bisexual bridge’’ of HIV transmission connecting these two subpopulations of the Black community. Specifically, bisexually active Black men who identify as heterosexual but do not disclose their same-sex behavior, or ‘‘down low’’ (DL) men, have received the most attention and blame as the primary group fueling this epidemic. This essay explores the current knowledge and limitations of public health research on bisexually active Black men. Implications for future research initiatives are discussed.

Helical tomotherapy (HT) is a novel technique to deliver intensity modulated radiation therapy guided by 3D megavoltage CT imaging. The purpose of our study is to assess the dosimetric parameters related to HT and 3DCRT in advanced non-small cell lung cancer (NSCLC). Eleven patients from the London Regional Cancer Centre and the Cross Cancer Institute with NSCLC underwent individualized treatment planning on both HT and 3DCRT. Corresponding HT and 3DCRT plans for each patient were analyzed using dose-volume histograms for GTV, PTV (median dose 60Gy/30 fractions), and critical structures (lung V5-30, esophageal V50-60, and spinal cord D1). Observed differences in …
