Department of Microbiology and Immunology Faculty Papers

The heterotrimeric guanine nucleotide-binding protein Galphai2 is involved in regulation of immune responses against microbial and nonmicrobial stimuli. Galphai2-/- mice have a selectively impaired IgM response consistent with a disorder in B cell development yet have augmented T cell effector function associated with increased production of IFN-gamma and IL-4. The goal of the present study was to determine if a deficiency in the Galphai2 protein in mice would affect the protective immune response against Strongyloides stercoralis, which is IL-4-, IL-5-, and IgM-dependent. Galphai2-/- and wild-type mice were immunized and challenged with S. stercoralis larvae and analyzed for protective immune responses …


Transitioning From Acute Care To Ambulatory Care, Beth Ann Swan Mar 2007

Transitioning From Acute Care To Ambulatory Care, Beth Ann Swan

College of Nursing Faculty Papers & Presentations

Trends in health care financing and changes in care delivery from the hospital to outpatient settings have caused an unprecedented demand for registered nurses in ambulatory care.

Nurses transition to ambulatory care expecting to use the same knowledge base and skill set used in their acute care practice.

While some knowledge and skills may be transferable, competencies (and additional knowledge and skills) needed by acute care nurses and ambulatory care nurses are not the same.

The purpose of this article to is describe and dispel myths associated with ambulatory care nursing practice and discuss the knowledge, skills, and competencies that …


Expression Of The Autoimmune Fcgr2b Nzw Allele Fails To Be Upregulated In Germinal Center B Cells And Is Associated With Increased Igg Production, S.M. Ziaur Rahman, H. Niu, D. Perry, Timothy L. Manser, L. Morel Mar 2007

Expression Of The Autoimmune Fcgr2b Nzw Allele Fails To Be Upregulated In Germinal Center B Cells And Is Associated With Increased Igg Production, S.M. Ziaur Rahman, H. Niu, D. Perry, Timothy L. Manser, L. Morel

Department of Microbiology and Immunology Faculty Papers

The inhibitory receptor FcγRIIb regulates B-cell functions. Genetic studies have associated Fcgr2b polymorphisms and lupus susceptibility in both humans and murine models, in which B cells express reduced FcγRIIb levels. Furthermore, FcγRIIb absence results in lupus on the appropriate genetic background, and lentiviral-mediated FcγRIIb overexpression prevents disease in the NZM2410 lupus mouse. The NZM2410/NZW allele Fcgr2b is, however, located in-between Sle1a and Sle1b, two potent susceptibility loci, making it difficult to evaluate Fcr2bNZW independent contribution. By using two congenic strains that each carries only Sle1a (B6.Sle1a(15–353)), or Fcr2bNZW in the absence of Sle1a or Sle1b (B6.Sle1(111–148)), we show that the …

Patient Advocacy Resource Manual, Jeff Hope Mar 2007

Patient Advocacy Resource Manual, Jeff Hope

Student Organizations

Patient Advocacy began as a freestanding group, formed by medical students who wanted to help homeless men and women with their psychosocial needs, such as finding a job, obtaining health insurance, and joining a drug and alcohol rehabilitation program. Later, we merged with Jeff HOPE to form an organization that can address all of the needs of our patients. This combination of energies and talents has proven quite beneficial, especially because our patients often need services that are beyond the scope of what the Jeff HOPE medical clinic can provide. Thus, one of our most important responsibilities is to link …

Cell Fate Determination Factor Dach1 Inhibits C-Jun-Induced Contact-Independent Growth, Kongming Wu, Manran Liu, Anping Li, Howard Donninger, Mahadev Rao, Xuanmao Jiao, Michael P. Lisanti, Ales Cvekl, Michael Birrer, Richard G. Pestell

Department of Cancer Biology Faculty Papers

The cell fate determination factor DACH1 plays a key role in cellular differentiation in metazoans. DACH1 is engaged in multiple context-dependent complexes that activate or repress transcription. DACH1 can be recruited to DNA via the Six1/Eya bipartite transcription (DNA binding/coactivator) complex. c-Jun is a critical component of the activator protein (AP)-1 transcription factor complex and can promote contact-independent growth. Herein, DACH1 inhibited c-Jun-induced DNA synthesis and cellular proliferation. Excision of c-Jun with Cre recombinase, in c-jun(f1/f1) 3T3 cells, abrogated DACH1-mediated inhibition of DNA synthesis. c-Jun expression rescued DACH1-mediated inhibition of cellular proliferation. DACH1 inhibited induction of c-Jun by physiological stimuli …

Association Of The Tensin N-Terminal Protein-Tyrosine Phosphatase Domain With The Alpha Isoform Of Protein Phosphatase-1 In Focal Adhesions, Masumi Eto, Jason Kirkbride, Elizabeth Elliott, Su Hao Lo, David L. Brautigan

Department of Molecular Physiology and Biophysics Faculty Papers

Focal adhesions attach cultured cells to the extracellular matrix, and we found endogenous protein phosphatase-1alpha isoform (PP1alpha) localized in adhesions across the entire area of adherent fibroblasts. However, in fibroblasts migrating into a scrape wound or spreading after replating PP1alpha did not appear in adhesions near the leading edge but was recruited into other adhesions coincident in time and space with incorporation of tensin. Endogenous tensin and PP1alpha co-precipitated from cell lysates with isoform-specific PP1 antibodies. Chemical cross-linking of focal adhesion preparations with Lomant's reagent demonstrated molecular proximity of endogenous PP1alpha and tensin, whereas neither focal adhesion kinase nor vinculin …

Department of Medicine Faculty Papers

Millions of women still use postmenopausal hormone therapy (HT). We genotyped 2090 women in Heart and Estrogen/progestin Replacement Study for functional polymorphisms in GP1BA and GP6 and assessed the coronary heart disease (CHD) event rate over 5.8 years of follow-up. In patients receiving placebo, there was an increased CHD death/myocardial infarction (MI)/unstable angina (UA) event rate in carriers of the GP1BA -5C allele (adjusted [adj] P = .006). HT increased the hazard ratio (HR) of CHD events in patients with the GP1BA -5TT genotype by 16% and reduced the HR in patients with the TC+CC genotypes by 46% (adj interaction …

Department of Occupational Therapy Faculty Papers

OBJECTIVE: We sought to assess validity of sensory integration outcomes research in relation to fidelity (faithfulness of intervention to underlying therapeutic principles).

METHOD: We identified core sensory integration intervention elements through expert review and nominal group process. Elements were classified into structural (e.g., equipment used, therapist training) and therapeutic process categories. We analyzed 34 sensory integration intervention studies for consistency of intervention descriptions with these elements.

RESULTS: Most studies described structural elements related to therapeutic equipment and interveners' profession. Of the 10 process elements, only 1 (presentation of sensory opportunities) was addressed in all studies. Most studies described fewer than …

Department of Occupational Therapy Faculty Papers

Goal attainment scaling (GAS) is a methodology that shows promise for application to intervention effectiveness research and program evaluation in occupational therapy (Dreiling & Bundy, 2003; King et al., 1999; Lannin, 2003; Mitchell & Cusick, 1998). This article identifies the recent and current applications of GAS to occupational therapy for children with sensory integration dysfunction, as well as the process, usefulness, and problems of application of the GAS methodology to this population. The advantages and disadvantages of using GAS in single-site and multisite research with this population is explored, as well as the potential solutions and future programs that will …


Three-Portal Technique For Anterior Cruciate Ligament Reconstruction: Use Of A Central Medial Portal, Steven B. Cohen, Freddie H. Fu Mar 2007

Three-Portal Technique For Anterior Cruciate Ligament Reconstruction: Use Of A Central Medial Portal, Steven B. Cohen, Freddie H. Fu

Department of Orthopaedic Surgery Faculty Papers

Standard endoscopic reconstruction of the anterior cruciate ligament (ACL) is performed with the use of 2 arthroscopic portals. The surgical error most commonly associated with ACL reconstruction is improper positioning of the tunnel. Errors in femoral tunnel position may be related to poor visualization of the lateral wall. When anatomic double-bundle ACL reconstruction is performed, proper visualization of the lateral wall is essential to ensure correct placement of both tunnels. We propose the use of a central portal, in addition to more standard anterolateral and anteromedial portals, to enhance visualization of the lateral wall. In addition, the arthroscope can be …


Untangling The Signalling Wires, Boris N. Kholodenko Phd, Dsci Mar 2007

Untangling The Signalling Wires, Boris N. Kholodenko Phd, Dsci

Department of Pathology, Anatomy, and Cell Biology Faculty Papers

Mitogen-activated protein kinase (MAPK) cascades process myriads of stimuli, generating receptor-specific cellular outcomes. New work exploits emergent mathematics of network inference to reveal distinct feedback designs of the RAF/MEK/ERK cascade induced by two different growth factors. It shows that response specificity can arise from differential signal-induced wiring of overlapping protein networks.

The Functional Significance Of Nuclear Receptor Acetylation., Vladimir M. Popov, Chenguang Wang, L . Andrew Shirley, Anne Rosenberg, Shengwen Li, Marja Nevalainen, Maofu Fu, Richard G. Pestell

Department of Cancer Biology Faculty Papers

The endocrine signaling governing nuclear receptor (NR) function has been known for several decades to play a crucial role in the onset and progression of several tumor types. Notably among these are the estrogen receptor (ER) in breast cancer and androgen receptor (AR) in prostate cancer. Other nuclear receptors may be involved in cancer progression including the peroxisome-proliferator activating receptor gamma (PPARgamma), which has been implicated in breast, thyroid, and colon cancers. These NR are phylogenetically conserved modular transcriptional regulators, which like histones, undergo post-translational modification by acetylation, phosphorylation and ubiquitination. Importantly, the transcriptional activity of the receptors is governed …


Somatic Excision Demonstrates That C-Jun Induces Cellular Migration And Invasion Through Induction Of Stem Cell Factor, Sanjay Katiyar, Xuanmao Jiao, Erwin Wagner, Michael P. Lisanti, Richard G. Pestell Feb 2007

Somatic Excision Demonstrates That C-Jun Induces Cellular Migration And Invasion Through Induction Of Stem Cell Factor, Sanjay Katiyar, Xuanmao Jiao, Erwin Wagner, Michael P. Lisanti, Richard G. Pestell

Department of Cancer Biology Faculty Papers

Cancer cells arise through sequential acquisition of mutations in tumor suppressors and oncogenes. c-Jun, a critical component of the AP-1 complex, is frequently overexpressed in diverse tumor types and has been implicated in promoting cellular proliferation, migration, and angiogenesis. Functional analysis of candidate genetic targets using germ line deletion in murine models can be compromised through compensatory mechanisms. As germ line deletion of c-jun induces embryonic lethality, somatic deletion of the c-jun gene was conducted using floxed c-jun (c-junf/f) conditional knockout mice. c-jun-deleted cells showed increased cellular adhesion, stress fiber formation, and reduced cellular migration. The reduced migratory …

Cephalalgiaphobia: A Possible Specific Phobia Of Illness., Mario F P Peres, Juliane P P Mercante, Vera Z Guendler, Felipe Corchs, Marcio A Bernik, Eliova Zukerman, Stephen Silberstein

Department of Jefferson Headache Center Papers and Presentations

Psychiatric comorbidity, mainly anxiety and depression, are common in chronic migraine (CM). Phobias are reported by half of CM patients. Phobic avoidance associated with fear of headache or migraine attack has never been adequately described. We describe 12 migraine patients with particular phobic-avoidant behaviours related to their headache attacks, which we classified as a specific illness phobia, coined as cephalalgiaphobia. All patients were women, mean age 42, and all had a migraine diagnosis (11 CM, all overused acute medications). Patients had either a phobia of a headache attack during a pain-free state or a phobia of pain worsening during mild …
