Gingival Abscess Removal Using A Soft-Tissue Laser, Soni Prasad, Edward A. Monaco, Jr., Sebastiano Andreana

School of Dentistry Faculty Research and Publications

Gingival abscess, also known as parulis, is defined as a localized, acute inflammatory lesion that may arise from a number of sources, including microbial plaque infection, trauma, and foreign body impaction. It often presents as a smooth, fluctuant, red-color swelling and can occasionally be painful. It is generally limited to marginal and interdental gingiva. Based on its location it has been classified as a type of periodontal abscess which does not involve any attachment loss. The treatment comprises of removal of the cause and, in acute situations, excision of the abscess. A typical gingival abscess is easy to diagnose; however, …

The Epithelioid Blue Nevus: A Rare Intraoral Nevomelanocytic Tumor, Atef Hanna, Swati Y. Rawal, Kenneth M. Anderson, Yeshwant B. Rawal

School of Dentistry Faculty Research and Publications

The epithelioid blue nevus (EBN) is considered a cutaneous marker of the Carney complex. Sporadic EBN has been reported in patients not exhibiting the Carney complex. The EBN does not exhibit unique clinical features that help to differentiate it from other lesions and is often provisionally diagnosed as an acquired melanocytic nevus, or a malignant melanoma. A 52-year-old African-American female had a 3-4 mm bluish macule of the left anterior hard palate. An excisional biopsy was performed to rule out an incipient melanoma. Formalin-fixed, hematoxylin and eosin-stained sections were examined microscopically. On the basis of histopathological features, a diagnosis of …

The Association Of Religiosity, Sexual Education, And Parental Factors With Risky Sexual Behaviors Among Adolescents And Young Adults, Kristin Haglund, Richard J. Fehring

College of Nursing Faculty Research and Publications

This study examined the association of religiosity, sexual education and family structure with risky sexual behaviors among adolescents and young adults. The nationally representative sample, from the 2002 National Survey of Family Growth, included 3,168 women and men ages 15–21 years. Those who viewed religion as very important, had frequent church attendance, and held religious sexual attitudes were 27–54% less likely to have had sex and had significantly fewer sex partners than peers. Participants whose formal and parental sexual education included abstinence and those from two-parent families were 15% less likely to have had sex and had fewer partners.

Levo-Tetrahydropalmatine Attenuates Cocaine Self-Administration Under A Progressive-Ratio Schedule And Cocaine Discrimination In Rats, John R. Mantsch, Samantha Wisniewski, Oliver Vranjkovic, Corey Peters, Amanda Becker, Abbey Valentine, Shi-Jiang Li, David A. Baker, Zheng Yang

Biomedical Sciences Faculty Research and Publications

Levo-tetrahydropalmatine (l-THP) is an alkaloid found in many traditional Chinese herbal preparations and has a unique pharmacological profile that includes dopamine receptor antagonism. Previously we demonstrated that l-THP attenuates fixed-ratio (FR) cocaine self-administration (SA) and cocaine-induced reinstatement in rats at doses that do not alter food-reinforced responding. This study examined the effects of l-THP on cocaine and food SA under progressive-ratio (PR) schedules of reinforcement and the discriminative stimulus effects of cocaine. In adult male Sprague–Dawley rats self-administering cocaine (0.5 or 1.0 mg/kg/inf), l-THP significantly reduced breaking points at the 1.875, 3.75 and 7.5 mg/kg …

College of Nursing Faculty Research and Publications

Little is known about the role of nurse researchers (NRs) and the structure of nursing research programs in children's hospitals in the United States. This descriptive study obtained survey data from 33 NRs. Data suggest that the NR role is emerging and has both commonalities and unique components when compared with the previous studies of NRs in adult hospitals. Most participants have been in their position for less than 4 years. Conducting research, having staff development related to research, and facilitating evidence-based practice or research were common responsibilities. The structure of nursing research programs impacts both the NRs and the …

The Association Of Spirituality, Religiosity, Depression, Anxiety, And Drug Use Among Persons Undergoing Methadone Maintenance Therapy, Linda B. Piacentine

Dissertations (1934 -)

The Substance Abuse and Mental Health Services Administration estimated 22.2 million (9.1 %) of Americans ages 12 and older abused or were dependent on an illicit substance or alcohol in 2005. Substance abuse often leads to addiction, and is damaging to the health of persons, families, and society.

Using Neuman's System Model as the conceptual framework, it was proposed that addiction weakens person's defenses with resultant loss of health. The person with addiction often also suffers from anxiety, depression, or both, increasing the risk for continued substance abuse and its concomitant negative consequences, such as loss of employment, poor finances, …

More Than S.K.I.N. Deep: Decreasing Pressure Ulcer Development In The Pediatric Intensive Care Unit, Christine A. Schindler

Dissertations (1934 -)

Pressure ulcers are defined as localized areas of tissue destruction that develop when soft tissue is compressed between a bony prominence and an external surface for a prolonged period of time. Although any hospitalized child is at risk for the development of a pressure ulcer, the critically ill child is at increased risk. The critical care environment poses special challenges to preventing the development of pressure ulcers secondary to the high acuity of patients and the highly invasive nature of interventions and therapies those patients receive. The incidence of pediatric pressure ulcer development in the critical care population has been …

The Lived Experience Of Hispanic New Graduate Nurses In The United States, Esther Morales

Dissertations (1934 -)

There has been a significant increase in the Hispanic population in the United States that is not mirrored by representation of Hispanic registered nurses in the United States . Hispanic new graduate nurses enter nursing practice with few Hispanic role models and their story is not found in nursing literature. A qualitative study with a phenomenological philosophy and methodology was conducted to investigate the lived experience of seven Mexican American new graduate nurses, a subgroup of Hispanic nurses. Findings of this study were the seven themes: (a) being an employee; (b) an orientation with or without preceptors; (c) a transition; …

The Transition From Hospital To Home In Parents Of Pediatric Solid Organ Transplant Recipients, Stacee M. Lerret

Dissertations (1934 -)

Readiness for hospital discharge is an under-investigated topic in pediatric solid organ transplant. The immediate post-operative period and first few weeks after transplant are a critical time period where patients are at high risk for transplant-related complications.

A correlation design framed by Meleis' Transitions Theory were used to determine; (1) the influences of discharge teaching and care coordination on parent readiness for hospital discharge among parents of children who have experienced solid organ transplantation; and (2) the relationship of parent readiness for hospital discharge with coping, adherence difficulty, utilization of healthcare resources, and family impact in the first three weeks …

Trail, Dr5 And Caspase 3-Dependent Apoptosis In Vessels Of Diseased Human Temporomandibular Joint Disc. An Immunohistochemical Study, Carla Loreto, Luis Eduardo Almeida, M. R. Migliore, M. Caltabiano, Rosalia Leonardi

School of Dentistry Faculty Research and Publications

To evaluate the apoptosis involvement in the angiogenesis as a self-limiting process in patients with temporomandibular joint (TMJ) degenerated disc vessels, we assessed, by immunohistochemistry, the detection of TRAIL, its death receptor DR5 and caspase 3. TRAIL, its death receptor DR5 and caspase 3 expression were studied by immunohistochemistry in 15 TMJ discs displaced without reduction and in 4 unaffected discs. These apoptosis molecules were detected in the intima and media layers of newly formed vessels affected discs. In conclusion, vessels apoptosis activation in TMJ disc with ID could be regarded as a self-limiting process that try to leads to …

The Relationship Of Two Types Of Trauma Exposure To Current Physical And Psychological Symptom Distress In A Community Sample Of Colombian Women: Why Interpersonal Violence Deserves More Attention, Ruth Ann Belknap, Ashley Marie Schumacher, Bernal De Pheils, Janice Carrol Humphreys, Diva Jaramillo, Agnes Tiwari, Gladys Eugenia Canaval

College of Nursing Faculty Research and Publications

Our purpose in this study was to examine the relationship between interpersonal violence and background traumas and symptom distress in a community sample of Colombian women (N = 217). We utilized the Life Stressor Checklist-Revised (LSC-R) to measure lifetime interpersonal violence (IPV) and background trauma exposure and the Brief Symptom Inventory (BSI) to measure current symptom distress. Although both exposures were common in this sample, IPV was strongly correlated with current symptom distress; background traumas made no unique contribution to the variance in current symptom distress. Based on our findings, it is suggested that interpersonal events may be particularly …

Effects Of Hypothyroidism On Cell Proliferation And Neuroblasts In The Hippocampal Dentate Gyrus In A Rat Model Of Type 2 Diabetes, Sun Shin Yi, In Koo Hwang, Ji Won Choi, Moo-Ho Won, Je Kyung Seong, Yeo Sung Yoon

Biomedical Sciences Faculty Research and Publications

We observed how the hypothyroid state affects diabetic states and modifies cell proliferation and neuroblast differentiation in the hippocampal dentate gyrus (DG). For this, 0.03% methimazole, an anti-thyroid drug, was administered to 7-week-old, pre-diabetic Zucker diabetic fatty (ZDF) rats by drinking water for 5 weeks, and the animals were sacrificed at 12 weeks of age. At this age, corticosterone levels were significantly increased in the ZDF rats compared to those in the control (Zucker lean control, ZLC) rats. Methimazole (methi) treatment in the ZDF rats (ZDF-methi rats) significantly decreased corticosterone levels and diabetes-induced hypertrophy of adrenal glands. In the DG, …

Molecular Requirements For Ethanol Differential Allosteric Modulation Of Ligand-Gated Ion Channels Based On Selective Gβγ Modulation, Gonzalo E. Yevenes, Gustavo Moraga-Cid, Ariel Avila, Leonardo Guzman, Maximiliano Figueroa, Robert W. Peoples, Luis G. Aguayo

Biomedical Sciences Faculty Research and Publications

It is now believed that the allosteric modulation produced by ethanol in glycine receptors (GlyRs) depends on alcohol binding to discrete sites within the protein structure. Thus, the differential ethanol sensitivity of diverse GlyR isoforms and mutants was explained by the presence of specific residues in putative alcohol pockets. Here, we demonstrate that ethanol sensitivity in two LGIC members, the GlyR adult α₁ and embryonic α₂ subunits, can be modified through selective mutations that rescued or impaired Gβγ modulation. Even though that both isoforms were able to physically interact with Gβγ, only the α₁ GlyR was functionally …

Soft Tissue Grafting To Improve Implant Esthetics, Moawi M. Kassab

School of Dentistry Faculty Research and Publications

Dental implants are becoming the treatment of choice to replace missing teeth, especially if the adjacent teeth are free of restorations. When minimal bone width is present, implant placement becomes a challenge and often resulting in recession and dehiscence around the implant that leads to subsequent gingival recession. To correct such defect, the author turned to soft tissue autografting and allografting to correct a buccal dehiscence around tooth #24 after a malpositioned implant placed by a different surgeon. A 25-year-old woman presented with the chief complaint of gingival recession and exposure of implant threads around tooth #24. The patient received …

Transcriptional Profiles For Glutamate Transporters Reveal Differences Between Organophosphates But Similarities With Unrelated Neurotoxicants, Theodore A. Slotkin, Doug Lobner, Frederic J. Seidler

Biomedical Sciences Faculty Research and Publications

The developmental neurotoxicity of organophosphates involves mechanisms other than their shared property as cholinesterase inhibitors, among which are excitotoxicity and oxidative stress. We used PC12 cells as a neurodevelopmental model to compare the effects of chlorpyrifos and diazinon on the expression of genes encoding glutamate transporters. Chlorpyrifos had a greater effect in cells undergoing nerve growth factor-induced neurodifferentiation as compared to undifferentiated PC12 cells, with peak sensitivity at the initiation of differentiation, reflecting a global upregulation of all the glutamate transporter genes expressed in this cell line. In differentiating cells, chlorpyrifos had a significantly greater effect than did diazinon and …

Synaptotoxicity Of Alzheimer Beta Amyloid Can Be Explained By Its Membrane Perforating Property, Fernando Sepulveda, Jorge Parodi, Robert W. Peoples, Carlos Opazo, Luis G. Aguayo

Biomedical Sciences Faculty Research and Publications

The mechanisms that induce Alzheimer’s disease (AD) are largely unknown thereby deterring the development of disease-modifying therapies. One working hypothesis of AD is that Aβ excess disrupts membranes causing pore formation leading to alterations in ionic homeostasis. However, it is largely unknown if this also occurs in native brain neuronal membranes. Here we show that similar to other pore forming toxins, Aβ induces perforation of neuronal membranes causing an increase in membrane conductance, intracellular calcium and ethidium bromide influx. These data reveal that the target of Aβ is not another membrane protein, but that Aβ itself is the cellular target …

Involvement Of Noradrenergic Neurotransmission In The Stress- But Not Cocaine-Induced Reinstatement Of Extinguished Cocaine-Induced Conditioned Place Preference In Mice: Role For Β-2 Adrenergic Receptors, John R. Mantsch, Andy Meyer, Oliver Vranjkovic, Chad E. Beyer, David A. Baker, Holly Caretta

Biomedical Sciences Faculty Research and Publications

The responsiveness of central noradrenergic systems to stressors and cocaine poses norepinephrine as a potential common mechanism through which drug re-exposure and stressful stimuli promote relapse. This study investigated the role of noradrenergic systems in the reinstatement of extinguished cocaine-induced conditioned place preference by cocaine and stress in male C57BL/6 mice. Cocaine- (15 mg/kg, i.p.) induced conditioned place preference was extinguished by repeated exposure to the apparatus in the absence of drug and reestablished by a cocaine challenge (15 mg/kg), exposure to a stressor (6-min forced swim (FS); 20–25°C water), or administration of the α-2 adrenergic receptor (AR) antagonists yohimbine …
