A Pdz-Binding Motif Is Essential But Not Sufficient To Localize The C Terminus Of Cftr To The Apical Membrane, Michal I. Milewski, John E. Mickle, John K. Forrest, Diane M. Stafford, Bryan D. Moyer, Jie Cheng, William B. Guggino, Bruce A. Stanton, Garry R. Cutting

Dartmouth Scholarship

Localization of ion channels and transporters to the correct membrane of polarized epithelia is important for vectorial ion movement. Prior studies have shown that the cytoplasmic carboxyl terminus of the cystic fibrosis transmembrane conductance regulator (CFTR) is involved in the apical localization of this protein. Here we show that the C-terminal tail alone, or when fused to the green fluorescent protein (GFP), can localize to the apical plasma membrane, despite the absence of transmembrane domains. Co-expression of the C terminus with full-length CFTR results in redistribution of CFTR from apical to basolateral membranes, indicating that both proteins interact with the …

Anger, Child Behavior, And Family Distress: Further Evaluation Of The Parental Anger Inventory, Georganna Sedlar, David J. Hansen

Department of Psychology: Faculty Publications

Presumably, anger is a common experience of parenting. Although practitioners and researchers recognize the role of anger in various parenting situations, objective and standardized measures of parental anger have been notably lacking in the field. This study examined the Parental Anger Inventory (PAI), a measure developed specifically to assess parental anger in response to child misbehavior. A diverse sample of 98 parents participated in the study, including (a) physically abusive or neglectful parents, or both, n = 44; (b) nonmaltreating clinic parents seeking assistance for child behavior problems, n = 24; and (c) nonmaltreating, non–help-seeking community parents, n = 30. …

Analysis Of Mitotic Microtubule-Associated Proteins Using Mass Spectrometry Identifies Astrin, A Spindle-Associated Protein, Gary J. Mack, Duane A. Compton

Dartmouth Scholarship

We purified microtubules from a mammalian mitotic extract and obtained an amino acid sequence from each microtubule-associated protein by using mass spectrometry. Most of these proteins are known spindle-associated components with essential functional roles in spindle organization. We generated antibodies against a protein identified in this collection and refer to it as astrin because of its association with astral microtubule arrays assembled in vitro. Astrin is approximately 134 kDa, and except for a large predicted coiled-coil domain in its C-terminal region it lacks any known functional motifs. Astrin associates with spindle microtubules as early as prophase where it concentrates at …

Evaluation Of Directly Observed Therapy In Pulmonary Tuberculosis Patients In Nepal: Treatment Outcome And Patient Compliance, Baishali Bhattacharya

Masters Theses & Specialist Projects

Tuberculosis is the leading cause of infectious disease in Nepal. An estimated 60% of the adult population aged between 15-45 years is infected with tuberculosis, and 45% of the total population is infected. Ten percent of people infected with TB progress to active disease. To combat tuberculosis, Directly Observed Therapy (DOT) was adopted in Nepal in 1996. DOT was administered at four national demonstration sites in 1996 and expanded over time so that 56% of the population to date have been covered by DOT. This study aimed to evaluate DOT in pulmonary TB patients in Nepal in terms of patient …

Inheritance Of Dorsal Fin Coloration In The Metriaclima Species Complex (Teleostei: Cichlidae) Of Lake Malawi, Paulette Reneau

Masters Theses & Specialist Projects

The rock-dwelling cichlids (mbuna) of Lake Malawi have undergone an explosive evolution, giving rise to an assemblage of 300-500 species within the last one million years. Most widespread mbuna 'species' are characterized by the presence of local endemic populations, differing primarily in coloration and often of uncertain taxonomic rank. The recency and rapidity of speciation within the mbuna have led to difficulties in reconstructing an accurate species-level phylogeny, in turn limiting our ability to elucidate the evolutionary dynamics associated with divergence of coloration and other characters. Based on morphometric and meristic characters, Stauffer et al. (1997) erected a new genus …

Anatomy And Three-Dimensional Reconstructions Of The Brain Of The White Whale (Delphinapterus Leucas) From Magnetic Resonance Images, Lori Marino, Timothy L. Murphy, Amy L. Deweerd, John A. Morris, Archibald J. Fobbs, Nathalie Humbolt, Sam H. Ridgway, John I. Johnson

Veterinary Science and Medicine Collection

Magnetic resonance imaging offers a means of observing the internal structure of the brain where traditional procedures of embedding, sectioning, staining, mounting, and microscopic examination of thousands of sections are not practical. Furthermore, internal structures can be analyzed in their precise quantitative spatial interrelationships, which is difficult to accomplish after the spatial distortions often accompanying histological processing. For these reasons, magnetic resonance imaging makes specimens that were traditionally difficult to analyze, more accessible. In the present study, images of the brain of a white whale (Beluga) Delphinapterus leucas were scanned in the coronal plane at 119 antero-posterior levels. Fromthese scans, …

Anatomy And Three-Dimensional Reconstructions Of The Brain Of A Bottlenose Dolphin (Tursiops Truncatus) From Magnetic Resonance Images, Lori Marino, Keith D. Sudheimer, Timothy L. Murphy, Kristina K. Davis, D. Ann Pabst, William A. Mclellan, James K. Rilling, John I. Johnson

Veterinary Science and Medicine Collection

Cetacean (dolphin, whale, and porpoise) brains are among the least studied mammalian brains because of the formidability of collecting and histologically preparing such relatively rare and large specimens. Magnetic resonance imaging offers a means of observing the internal structure of the brain when traditional histological procedures are not practical. Furthermore, internal structures can be analyzed in their precise anatomic positions, which is difficult to accomplish after the spatial distortions often accompanying histological processing. In this study, images of the brain of an adult bottlenose dolphin, Tursiops truncatus, were scanned in the coronal plane at 148 antero-posterior levels. From these scans …

Pretreatment Characteristics Of Legally Coerced Drug Treatment Seekers, Bridgett Augustino

Masters Theses & Specialist Projects

This study examines the sociodemographics, drug use, criminal, and treatment histories of 598 residential and outpatient legally coerced drug treatment seekers in the Kentucky Treatment Outcome and Performance Pilot Studies Enhancement Project. Analyses examined whether users/addicts entering chemical dependency treatment under legal coercion differed from nonlegally coerced treatment seekers. Stanley Cohen's theoretical model of social control provided the theoretical framework for the study. Results showed demographic and behavioral differences were noted between respondents under no coercion and those under legal coercion on gender, age, educational status, pretreatment criminality and current treatment modality.

The Effect Of Lead Acetate On The Susceptibility Of C3heb/Fej Mice Infected With The Parasite Trypanosoma Cruzi, Savonna Warren

Masters Theses & Specialist Projects

Lead has been mined by man for centuries with evidence of its use dating back 6000 years. Chronic exposure to lead can result in encephalopathy, anemia, and nephropathy. Today, cases of lead poisoning are uncommon; however, lead continues to be incorporated into the body through subclinical exposures. These low dosages of lead have been shown to have a deleterious effect on the immune system. Experimental animals exposed to low levels of lead are unable to effectively respond to a number of bacterial and viral challenges. The present study focuses on the relationship between lead and parasitic infection. Parasitemia, mortality, serum …

Expression Of Gus Gene In Tobacco (Nicotiana Tabacum) And Corn (Zea Mays) Using Dimboa-Resistant Agrobacterium Strains, Deepti Mohamalawari

Masters Theses & Specialist Projects

This thesis evaluates the ability of Agrobacterium tumefaciens strains resistant to the compound DIMBOA [2, 4-dihydroxy-7-methoxy-2h-l,4- benzoxazin-3(4H)-one] to infect corn. DIMBOA is a secondary plant metabolite and is believed to have antimicrobial properties and provides resistance to the plant against microbial infection. Agrobacteriummediated genetic transformation technique can be employed to genetically alter most dicotyledonous plant species. However, such transformation has been limited in monocotyledonous plants, especially corn. One of the factors responsible for this recalcitrance is the presence of DIMBOA in corn shoots. In this study, we proposed the use of DIMBOA- resistant strains of Agrobacterium tumefaciens, bearing binary plasmids …

Effects Of Antioxidant Supplementation With Vitamin E And Selenium On Cytokine Production In Mice Infected With Trypanosoma Cruzi, Dong Chen

Masters Theses & Specialist Projects

Dietary supplementation with the antioxidants vitamin E and selenium (Se) has been shown to be beneficial against the intracellular parasite Trypanosoma cruzi during experimental Chagas' disease. Supplementation of mice with vitamin E and selenium at levels well above the recommended daily allowance for these two substances results in significantly decreased parasitemia levels and increased longevity. However, the mechanistic role of the antioxidants in this process is not well understood. It is known that vitamin E and selenium can reduce oxidative stress and improve host immune responses. In addition, the synthesis of many regulatory cytokines is known to be influenced by …

Temporal, Perspectives, Dispositional Styles, And Subjective Well-Being, Mary Naeger

Masters Theses & Specialist Projects

This study investigated the relationship between time perspective (TP) and the personality dispositions of optimism, pessimism, and realism with regard to their proposed influence on three measures that collectively assessed subjective well-being (SWB). The Depression-Happiness Scale (McGreal & Joseph, 1993) assessed happiness or the presence of positive affect and the absence of negative affect, the cognitiveaffective components of SWB. The Satisfaction with Life Scale (SWLS) (Diener, Emmons, Larsen, & Griffin, 1985) provided the measurement of subjective life satisfaction, the essential final cognitive-judgmental component of SWB. The Life Orientation Scale-Revised (LOT-R) (Scheier, Carver, and Bridges, 1994) and a Reality Scale, composed …

Can Meaningful Effective Connectivities Be Obtained Between Auditory Cortical Regions?, M S Gonçalves, D A Hall, Ingrid Johnsrude, M P Haggard

Brain and Mind Institute Researchers' Publications

Structural equation modeling (SEM) of neuroimaging data can be evaluated both for the goodness of fit of the model and for the strength of path coefficients (as an index of effective connectivity). SEM of auditory fMRI data is made difficult by the necessary sparse temporal sampling of the time series (to avoid contamination of auditory activation by the response to scanner noise) and by the paucity of well-defined anatomical information to constrain the functional model. We used SEM (i.e., a model incorporating latent variables) to investigate how well fMRI data in four adjacent cortical fields can be described as an …

Research Collection School Of Economics

Purpose: A specific TLS-CHOP fusion gene resulting from the t(12;16) is present in at least 95% of myxoid liposarcomas (MLS). Three common forms of the TLS-CHOP fusion have been described, differing by the presence or absence of TLS exons 6-8 in the fusion product. Type 5-2 (also known as type II) consists of TLS exons 1-5 fused to CHOP exon 2; type 7-2 (also known as type I) also includes TLS exons 6 and 7 in the fusion, whereas type 8-2 (also known as type III) fuses TLS exons 1-8 to CHOP exon 2. We sought to determine the impact …

Dextran-Methylprednisolone Succinate As A Prodrug Of Methylprednisolone: Plasma And Tissue Disposition, Xiaoping Zhang, Reza Mehvar

Pharmacy Faculty Articles and Research

Plasma and tissue disposition of a macromolecular prodrug of methylprednisolone (MP), dextran (70 kDa)–methylprednisolone succinate (DMP), was studied in rats. Single 5‐mg/kg doses of DMP or unconjugated MP were administered into the tail veins of different groups of rats (n  = 4/group/time point). Blood (cardiac puncture) and tissues (liver, spleen, kidney, heart, lung, thymus, and brain) were collected at various times after DMP (0–96 h) or MP (0–2 h) injections. Concentrations of DMP and MP in samples were analyzed by size‐exclusion chromatography (SEC) and reversed‐phase high‐performance liquid chromatography (HPLC), respectively. Conjugation of MP with 70‐kDa dextran resulted in 22‐, …

A Decentralized, Patient-Centered Approach To Diabetes Disease Management In The Primary Care Setting, Michael Toscani, John P. O'Connor, David B. Nash

College of Population Health Faculty Papers

Although many disease management programs have been developed for diabetes, no single design has proved best for all providers and patient populations. Cost effectiveness is especially relevant to diabetes programs because significant costs of the disease may come from complications that occur later in life, while the costs of the program are incurred immediately. For this reason, diabetes disease management programs with positive outcomes and low implementation costs are of particular importance. We report here on the outcomes of a pilot test of the Steps to Health program developed by Abbott Laboratories. The Steps to Health program was designed to …

Multimodal Assessment Of The Effect Of Chewing Gum On Nicotine Withdrawal, Lee M. Cohen, Dana M. Britt, Frank L. Collins, Mustafa Al-Absi, Dennis E. Mcchargue

Department of Psychology: Faculty Publications

The present study was designed to evaluate the usefulness of chewing gum to reduce nicotine withdrawal, craving, and salivary cortisol concentrations during temporary nicotine deprivation. A total of 20 male smokers were studied under conditions when gum was and was not accessible during a 4-hour deprivation period. All subjects smoked an initial cigarette shortly after arrival for the two experimental sessions and were informed that they would be unable to smoke for the remainder of each session. The sessions consisted of each subject watching a movie, then waiting in the lab for two consecutive 30-min intervals. Self-reported nicotine withdrawal and …

Immune Response Genes Modulate Serologic Responses To Vibrio Cholerae Tcpa Pilin Peptides, Michael D. Meeks, Terri K. Wade, Ronald K. Taylor, William F. Wade

Dartmouth Scholarship

Cholera is an enteric disease caused by Vibrio cholerae. Toxin-coregulated pilus (TCP), a type 4 pilus expressed by V. cholerae, is a cholera virulence factor that is required for host colonization. The TCP polymer is composed of subunits of TcpA pilin. Antibodies directed against TcpA are protective in animal models of cholera. While natural or recombinant forms of TcpA are difficult to purify to homogeneity, it is anticipated that synthesized TcpA peptides might serve as immunogens in a subunit vaccine. We wanted to assess the potential for effects of the immune response (Ir) gene that could complicate a peptide-based …

Rumination And Cigarette Smoking: A Bad Combination For Depressive Outcomes?, Malia Richmond, Bonnie Spring, Beth Kaplan Sommerfeld, Dennis E. Mcchargue

Department of Psychology: Faculty Publications

Ruminative coping has been shown to heighten the risk and severity of depression. The authors hypothesized that ruminators who smoke would experience greater depressive symptoms than ruminators who do not. The rationale is that, by heightening attentional focus, nicotine may increase ruminators' ability to focus on negative thoughts, augmenting depressed mood. Participants (N = 145) self-reported smoking status, rumination, and current and lifetime depressive symptoms, including depressed mood. Results showed that rumination accounted for a larger amount of variance in current and past depressed mood and severity of lifetime depressive symptoms among smokers than nonsmokers. Noncorrelational, experimental research should …

Evaluation Of A Tetracycline-Inducible Promoter In Staphylococcus Aureus In Vitro And In Vivo And Its Application In Demonstrating The Role Of Sigb In Microcolony Formation, B. T. Bateman, N. P. Donegan, T. M. Jarry, M. Palma

Dartmouth Scholarship

An inducible promoter system provides a powerful tool for studying the genetic basis for virulence. A variety of inducible systems have been used in other organisms, including pXyl-xylR-inducible promoter, the pSpac-lacI system, and the arabinose-inducible P_BAD promoter, but each of these systems has limitations in its application to Staphylococcus aureus. In this study, we demonstrated the efficacy of a tetracycline-inducible promoter system in inducing gene expression in S. aureus in vitro and inside epithelial cells as well as in an animal model of infection. Using the xyl/tetO promoter::gfp_uvr fusion carried on a shuttle …

From Product Dispensing To Patient Care: The Role Of The Pharmacist In Providing Pharmaceutical Care As Part Of An Integrated Disease Management Approach, Laura T. Pizzi, Jean M. Menz, Geneen R. Graber, Dong-Churl Suh

College of Population Health Faculty Papers

During the past decade, the profession of pharmacy has changed dramatically. The Doctor of Pharmacy degree has replaced the Bachelor of Science degree as the first professional degree offered at most accredited U.S. pharmacy schools. Advanced clinical training is now a mainstay of pharmacy training, and this has enabled pharmacists to contribute to disease management efforts. In addition, technological improvements in prescription processing have afforded pharmacists more time to participate in disease management activities. This paper describes how the role of the pharmacist has changed and reviews the results of programs involving pharmacists as disease management providers in the areas …

Anti-Class Ii Monoclonal Antibody-Targeted Vibrio Cholerae Tcpa Pilin: Modulation Of Serologic Response, Epitope Specificity, And Isotype, Jia-Yan Wu, Ronald K. Taylor, William F. Wade

Dartmouth Scholarship

Toxin-coregulated pilus (TCP) is a colonization factor required for cholera infection. It is not a strong immunogen when delivered in the context of whole cells, yet pilus subunits or TcpA derivative synthetic peptides induce protective responses. We examined the efficacy of immunizing mice with TCP conjugated to anti-class II monoclonal antibodies (MAb) with or without the addition of cholera toxin (CT) or anti-CD40 MAb to determine if the serologic response to TcpA could be manipulated. Anti-class II MAb-targeted TCP influenced the anti-TCP peptide serologic response with respect to titer and isotype. Responses to TcpA peptide 4 were induced with class …

Evaluation Of Cholera Vaccines Formulated With Toxin-Coregulated Pilin Peptide Plus Polymer Adjuvant In Mice, Jia-Yan Wu, William F. Wade, Ronald K. Taylor

Dartmouth Scholarship

Cholera is an acute diarrheal disease that is caused by the gram-negative bacterium Vibrio cholerae. The low efficacy of currently available killed-whole-cell vaccines and the reactinogenicity coupled with potential reversion of live vaccines have thus far precluded widespread vaccination for the control of cholera. Recent studies on the molecular nature of the virulence components that contribute to V. cholerae pathogenesis have provided insights into possible approaches for the development of a defined subunit cholera vaccine. Genetic analysis has demonstrated that the toxin-coregulated pilus (TCP) is the major factor that contributes to colonization of the human intestine by V. cholerae. In …
