Phase I And Phase Ii Ocular Metabolic Activities And The Role Of Metabolism In Ophthalmic Prodrug And Codrug Design And Delivery, Abeer M. Al-Ghananeem, Peter A. Crooks

Pharmaceutical Sciences Faculty Publications

While the mammalian eye is seldom considered an organ of drug metabolism, the capacity for biotransformation is present. Compared to the liver, the metabolic capabilities of the eye are minuscule; however, phase I and phase II metabolic activities have been detected in various ocular structures. The careful consideration of ocular tissue metabolic processes within the eye has important implications for controlling the detoxification of therapeutic agents and for providing the potential for site-specific bio-activation of certain drug molecules, thus enabling significant improvements in drug efficacy and the minimization of side-effect from either local or systemic drug delivery to the eye. …

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 …

Toward A Biopsychosocial Understanding Of The Patient-Physician Relationship: An Emerging Dialogue, Herbert M. Adler

Department of Family & Community Medicine Faculty Papers

Complexity theory has been used to view the patient-physician relationship as constituted by complex responsive processes of relating. It describes an emergent, psychosocial relational process through which patients and physicians continually and reciprocally influence each other's behavior and experience. As psychosocial responses are necessarily biopsychosocial responses, patients and physicians must likewise be influencing each other's psychobiology. This mutual influence may be subjectively experienced as empathy, and may be skillfully employed by the clinician to directly improve the patient's psychobiology.

Phosphorylation Of The Proline-Rich Domain Of Xp95 Modulates Xp95 Interaction With Partner Proteins, Robert E Dejournett, Ryuji Kobayashi, Shujuan Pan, Chuanfen Wu, Laurence D Etkin, Richard B Clark, Oliver Bögler, Jian Kuang

Faculty, Staff and Student Publications

The mammalian adaptor protein Alix [ALG-2 (apoptosis-linked-gene-2 product)-interacting protein X] belongs to a conserved family of proteins that have in common an N-terminal Bro1 domain and a C-terminal PRD (proline-rich domain), both of which mediate partner protein interactions. Following our previous finding that Xp95, the Xenopus orthologue of Alix, undergoes a phosphorylation-dependent gel mobility shift during progesteroneinduced oocyte meiotic maturation, we explored potential regulation of Xp95/Alix by protein phosphorylation in hormone-induced cell cycle re-entry or M-phase induction. By MALDI-TOF (matrix-assisted laser-desorption ionization-time-of-flight) MS analyses and gel mobility-shift assays, Xp95 is phosphorylated at multiple sites within the N-terminal half of the …

Cholecystectomy Deferral In Patients With Endoscopic Sphincterotomy, Vivian Mcalister, Eric Davenport, Elizabeth Renouf

Surgery Publications

BACKGROUND: Cholecystectomy is not required in up to 64% of patients who adopt a wait-and-see policy after endoscopic clearance of common bile duct stones. Although reports of retrospective cohort series have shown a higher mortality among patients who defer cholecystectomy, it is not known if this is due to the patients' premorbid health status or due to the deferral of cholecystectomy. Randomised clinical trials of prophylactic cholecystectomy versus wait-and-see have not had sufficient power to demonstrate differences in survival.

OBJECTIVES: To evaluate the beneficial and harmful effects of cholecystectomy deferral (wait-and-see) versus elective (prophylactic) cholecystectomy in patients who have had …

Development Of Tilt Table With Visual Feedback Function For Hemiplegia Patients, J. Cho, J. Choi, T. Nam, J. Park, I. Park-Ko, F. Ibrahim

Research Publications (2006 to 2010)

Due to damaged vertebrae nerves, serious disease and aging, patients who have to lie down for long period of time need to exercise to maintain up-right standing position and recover their muscle power of paralytic leg. This study describes the development of an intelligent tilt table which can provide a patient with visual feedback of exercise to increase the effect of rehabilitation. This could be possible by measuring and displaying the knee bent angle and pressure for each foot during exercise in real time. It is expected that patient's exercising effect can increase by self-monitoring these two values during exercise.

Oxidative Dna Damage In Mild Cognitive Impairment And Late-Stage Alzheimer's Disease, Mark A. Lovell, William R. Markesbery

Chemistry Faculty Publications

Increasing evidence supports a role for oxidative DNA damage in aging and several neurodegenerative diseases including Alzheimer's disease (AD). Attack of DNA by reactive oxygen species (ROS), particularly hydroxyl radicals, can lead to strand breaks, DNA–DNA and DNA–protein cross-linking, and formation of at least 20 modified bases adducts. In addition, α,β-unsaturated aldehydic by-products of lipid peroxidation including 4-hydroxynonenal and acrolein can interact with DNA bases leading to the formation of bulky exocyclic adducts. Modification of DNA bases by direct interaction with ROS or aldehydes can lead to mutations and altered protein synthesis. Several studies of DNA base adducts in late-stage …

Human Health Risk Assessment For Aluminium, Aluminium Oxide, And Aluminium Hydroxide, Daniel Krewski, Robert A. Yokel, Evert Nieboer, David Borchelt, Joshua Cohen, Jean Harry, Sam Kacew, Joan Lindsay, Amal M. Mahfouz, Virginie Rondeau

Pharmaceutical Sciences Faculty Publications

A compendium is provided of aluminium compounds used in industrial settings, and as pharmaceuticals, food additives, cosmetics and as other household products. Most aluminium compounds are solids exhibiting high melting points. The solubility of aluminium salts is governed by pH, because the aluminium(III)-cation (Al³⁺) has a strong affinity for the hydroxide ion, which promotes precipitation. Like Mg²⁺ and Ca²⁺ ions, Al³⁺ in most situations seeks out complexing agents with oxygen-atom donor sites such as carboxylate and phosphate groups, including in biological systems. Aluminium oxides, hydroxides and oxyhydroxides occur in numerous crystallographic forms, which exhibit different …

The Interplay Of Obesity And Asthma, James Plumb, Rickie Brawer, Nancy Brisbon

Department of Family & Community Medicine Faculty Papers

The relationships, interactions, and association between obesity and asthma are complex, and are active sources of hypotheses and research. An association between obesity and asthma has been reported in many studies, although considerable debate about the existence of the association and its meaning still exists. Potential associative relationships may result from genetics, immune system modifications, and mechanical mechanisms. The rising prevalence of asthma and obesity in children and adults, and the significant morbidity from both, makes it imperative that clinicians recognize the importance of weight management in patients with and without asthma.

All In The Family: Atypical Hsp70 Chaperones Are Conserved Modulators Of Hsp70 Activity, Lance Shaner, Kevin A Morano

Faculty, Staff and Student Publications

Divergent relatives of the Hsp70 protein chaperone such as the Hsp110 and Grp170 families have been recognized for some time, yet their biochemical roles remained elusive. Recent work has revealed that these "atypical" Hsp70s exist in stable complexes with classic Hsp70s where they exert a powerful nucleotide-exchange activity that synergizes with Hsp40/DnaJ-type cochaperones to dramatically accelerate Hsp70 nucleotide cycling. This represents a novel evolutionary transition from an independent protein-folding chaperone to what appears to be a dedicated cochaperone. Contributions of the atypical Hsp70s to established cellular roles for Hsp70 now must be deciphered.

Computer Simulation Of Glioma Growth And Morphology, Hermann B. Frieboes, John S Lowengrub, S Wise, X Zheng, Paul Macklin, Elaine L. Bearer, Vittorio Cristini

Faculty, Staff and Student Publications

Despite major advances in the study of glioma, the quantitative links between intra-tumor molecular/cellular properties, clinically observable properties such as morphology, and critical tumor behaviors such as growth and invasiveness remain unclear, hampering more effective coupling of tumor physical characteristics with implications for prognosis and therapy. Although molecular biology, histopathology, and radiological imaging are employed in this endeavor, studies are severely challenged by the multitude of different physical scales involved in tumor growth, i.e., from molecular nanoscale to cell microscale and finally to tissue centimeter scale. Consequently, it is often difficult to determine the underlying dynamics across dimensions. New techniques …
