Diversion Of The Inferior Vena Cava Following Repair Of Atrial Septal Defect Causing Hypoxemia, Ellen A. Thompson, Silvestre Cansino, Dennis Moritz, Romaine Perdue Perdue
Internal Medicine
Atrial septal defects (ASDs) are a common congenital abnormality, and operative repair is a routine, safe procedure. Diversion of the inferior vena cava (IVC) into the left atrium is an unusual complication following ASD closure. We report a case that illustrates the problem created by this right-to-left shunt. A middle-aged woman underwent ASD repair. She developed hypoxemia postoperatively. A transthoracic echocardiogram confirmed a right-to-left shunt, found only with agitated saline injected into the femoral vein, not into the basilic vein. Surgical reexploration revealed a residual ASD diverting IVC flow into the left atrium, which was repaired with a pericardial patch. …

The Effects Of Self-Monitoring And Religious Self-Discrepancies On Negative Affect, John Parker
Masters Theses & Specialist Projects
According to Higgins's (1987) self-discrepancy theory, an individual's selfesteem is based upon fulfilling one's self-expectations or the expectations of significant others (e.g., spouse or parent). Failure to live up to these expectations results in greater levels of depression, anxiety, and lower self-esteem. Previous research has also found that those low in Snyder and Gangestad's (1986) self-monitoring construct are more influenced by their own expectations, while those high in self-monitoring are more influenced by others' expectations. It was predicted that Christians who are low in self-monitoring will have greater levels of depression and anxiety and lower self-esteem if they fail to …
Black And White: Structural And Functional Aspects Of Dermal Chromatophores Of The Marbled Whiptail Lizard (Cnemidophorus Marmoratus), James Swan
Masters Theses & Specialist Projects
The skin of reptiles is a complex organ with many sensory, regulatory and behavioral functions. Desert reptiles face a suite of challenges as their skin contacts hot-dry environmental surfaces. The marbled whiptail lizard, Cnemidophorus marmoratus (Lacertilia: Teiidae), is found in hot deserts of southeastern New Mexico and western Texas and is often above ground during the hottest times of the day. When active, these lizards encounter a broad range and intensity of visible and infrared wavelengths. The role of the integument in temperature regulation, although poorly understood, is critically important for these diurnal animals. Albedo, coloration, pattern, and in some …

Deletion Of The Na/K-Atpase Alpha1-Subunit Gene (Atp1a1) Does Not Prevent Cavitation Of The Preimplantation Mouse Embryo., L C Barcroft, A E Moseley, J B Lingrel, A J Watson
Obstetrics & Gynaecology Publications
Increases in Na/K-ATPase activity occur concurrently with the onset of cavitation and are associated with increases in Na(+)-pump subunit mRNA and protein expression. We have hypothesized that the alpha1-isozyme of the Na/K-ATPase is required to mediate blastocyst formation. We have tested this hypothesis by characterizing preimplantation development in mice with a targeted disruption of the Na/K-ATPase alpha1-subunit (Atp1a1) using embryos acquired from matings between Atp1a1 heterozygous mice. Mouse embryos homozygous for a null mutation in the Na/K-ATPase alpha1-subunit gene are able to undergo compaction and cavitation. These findings demonstrate that trophectoderm transport mechanisms are maintained in the absence of the …

Trust And Health Service Use, Jen Chen Huey
Mental Health Law & Policy Faculty Publications
The emergence of managed care into the health care system was intended to change the behaviors of both providers and patients to contain rising health care costs. These management strategies raise concerns about interference with professional trust relationships and its impact on access to care and quality of care, especially for disabled individuals with severe mental illness. Due to their vulnerability, they are less likely to advocate for themselves in receiving proper quality health care. In addition, distrust of health care systems is a prominent feature of this population because of their past experiences with systems of care and providers …

We examined whether excessive alcohol consumption was related to changes in plasma levels of noradrenaline (NA) and whether these changes recover following abstinence. We also explored whether there were differences in NA levels between Type I and Type II alcoholics and controls during active drinking and abstinence. Plasma concentrations of NA were determined in (1) 27 Caucasian men with alcohol dependence who were regularly drinking (active drinkers) within 24 hours of hospitalization, (2) 29 Caucasian alcohol-dependent men who were in remission (abstinent for a minimum of three months), and (3) 28 race- and gender-matched healthy controls. NA concentrations were significantly …

A Survey Of Floss Frequency, Habit, And Technique In A Hospital Dental Clinic And Private, Stuart Segelnick Dds, Ms
Individual Scholarship
The purpose of the study was to determine floss frequency, habits and techniques of patients entering a private periodontal office (office site) vs. a hospital dental clinic (hospital site). It was found that the flossing frequency in a hospital dental clinic is far less than in a private practice, and patients who do floss may not be using the proper flossing technique. Patients need more instruction and care with regard to their interproximal oral hygiene.

Identification Of A Novel Bovine Herpesvirus 1 Transcript Containing A Small Open Reading Frame That Is Expressed In Trigeminal Ganglia Of Latently Infected Cattle, Melissa Inman, Joe Zhou, Heather Webb, Clinton J. Jones
School of Veterinary and Biomedical Sciences: Faculty Publications
Bovine herpesvirus 1 (BHV-1), like other Alphaherpesvirinae subfamily members, establishes latency in sensory neurons. The latency-related (LR) RNA is abundantly expressed during latency, and expression of an LR protein is required for the latency reactivation cycle in cattle. Within LR promoter sequences, a 135-aminoacid open reading frame (ORF) was identified, ORF-E, that is antisense to the LR RNA. ORF-E is also downstream of the gene encoding the major viral transcriptional activator, bICP0. Strand-specific reverse transcription-PCR demonstrated that a transcript containing ORF-E was consistently expressed in trigeminal ganglia (TG) of latently infected calves, productively infected cultured cells, and acutely infected calves. …

Synthesis Of Nanocrystalline Nickel-Zinc Ferrites Via A Microemulsion Route, Vuk Uskoković, Miha Drofenik
Pharmacy Faculty Articles and Research
Nanostructured NiZn-ferrites were synthesized using a low-temperature co-precipitation method within the reverse micelles of ternary CTAB/1-hexanol/water microemulsions. The influence of pH on the precipitation reaction was investigated. It was found that a higher pH resulted in more crystalline particles. Subsequent oxidation of the ferrous ions precipitate, which leads to the formation of spinel ferrites, is discussed. Diffraction-lines broadening and specific surface area measurements yielded an average particle size of ~ 3 nm. The saturation magnetization of the samples was 20 times smaller than for traditionally synthesized NiZn-ferrites, while the coercivities were 10 - 100 times larger than bulk NiZn-ferrites, which …

Age-related hearing loss, known as presbyacusis, is characterized by the progressive deterioration of auditory sensitivity associated with the aging process and is the leading cause of adult auditory deficiency in the USA. Presbyacusis is described as a progressive, bilateral, high-frequency hearing loss that is manifested on audiometric assessment by a moderately sloping pure tone audiogram. Approximately 23% of the population between 65 and 75 years of age, and 40% of the population older than 75 years of age are affected by this condition. It was estimated in 1980 that 11% of the population was 76 years or older and this …

The Sexual Abuse Crisis In The Roman Catholic Church: What Psychologists And Counselors Should Know, Thomas G. Plante, Courtney Daniels
Psychology
Recent events regarding child sexual abuse committed by Roman Catholic priests in the Archdiocese of Boston and elsewhere have yet again resulted in a tremendous amount of media attention and frenzy regarding this topic. During 2002 alone, approximately 300 American Catholic priests, including several bishops, were accused of child sexual abuse. Many were forced to resign their positions while others were prosecuted and went to prison. Curiously, there still exist many myths and misperceptions about priests who sexually abuse children and their victims. Since psychologists and other mental health professionals are likely to interact with many who have been impacted …

Although neurological disease has been recognized since antiquity, neurology as a systematic clinical discipline is less than 130 years old. Neurological practice has traditionally been constrained by the complexity of the human nervous system, which has been slow to yield its secrets. Over the last three decades, however, clinical neurology has been transformed in terms of both diagnostics and therapeutics and now marches in lockstep with the cutting edge of medicine. Efficacious treatments are now available for the majority of neurological diseases, including epilepsy, migraine, Guillain-Barre syndrome, Parkinson's disease, multiple sclerosis, and ischemic stroke. This neurological revolution has been enabled …

Simulation Of Drosophila Circadian Oscillations, Mutations, And Light Responses By A Model With Vri, Pdp-1, And Clk, Paul Smolen, Paul E. Hardin, Brian S. Lo, Douglas A. Baxter, John H. Byrne
Faculty, Staff and Student Publications
A model of Drosophila circadian rhythm generation was developed to represent feedback loops based on transcriptional regulation of per, Clk (dclock), Pdp-1, and vri (vrille). The model postulates that histone acetylation kinetics make transcriptional activation a nonlinear function of [CLK]. Such a nonlinearity is essential to simulate robust circadian oscillations of transcription in our model and in previous models. Simulations suggest that two positive feedback loops involving Clk are not essential for oscillations, because oscillations of [PER] were preserved when Clk, vri, or Pdp-1 expression was fixed. However, eliminating positive feedback by fixing vri expression altered the oscillation period. Eliminating …

We present a system designed to study the pressure at various ‘hot spots’ on the back of the body and the deformation of the spine experienced by a patient when strapped to a spinal board, and the potential alleviation of both by the addition of an inflatable “spinal raft” (or other similar device). In measuring pressure we devised a system of air-filled sacks interfaced with a PC. Each sack, placed under a particular key point on the body, is inflated until its faces just begin to separate and a switch thereby opens. The pressure reading is then captured and displayed …

Himmelfarb Health Sciences Library librarians developed and taught "Introduction to Medical Informatics" to first-year medical students through the 2002/03 school year. In 2003/04, this course was restructured and integrated into the "Problem-Based Learning" (PBL) course taken by all first-year medical students. The goal was to improve resource selection and search skills, provide point-of-use learning and instruction, and to enhance the student experience. Librarians were assigned to individual PBL groups to act as advisors and guided the students through the informatics-related curriculum.
