    Notes: This paper presents theories of strategic nonmarket participation in majority-rule and executive institutions and develops from those theories a set of principles for nonmarket strategy. The theories are based on models of vote recruitment in client and interest-group politics and on models of common agency. The basic strategies developed are majority building, vote recruitment, agenda setting, rent-chain mobilization, majority protection, and competitive agenda setting and vote recruitment.

    Notes: This paper provides a theory of private politics in which an activist seeks to change the production practices of a firm for the purpose of redistribution to those whose interests it supports. The source of the activist's influence is the possibility of support for its cause by the public. The paper also addresses the issue of corporate social responsibility by distinguishing among corporate redistribution as motivated by profit maximization, altruism, and threats by the activist. Private politics and corporate social responsibility not only have a direct effect on the costs of the firm, but also have a strategic effect by altering the competitive positions affirms in an industry. From an integrated-strategy perspective the paper investigates the strategic implications of private politics and corporate social responsibility for the strategies of rival firms when one or both are targets of an activist campaign. Implications for empirical analysis are derived from the theory.

    Notes: There is evidence that the oral contraceptive pill (OCP) and smoking contribute independently to risk of circulatory disease. There is mixed evidence that the combined risk may be greater than the sum of these factors operating in isolation. Little is known about how the general population views the risks from OCP use, singly and in combination with smoking. Previous attempts at assessing whether the public views risks as operating synergistically have generally found evidence for subadditive models, where the combined risk is less than the sum of factors operating in isolation. However, concerns have been expressed over the validity of the measures of risk perception used. Therefore, this study used three distinct methods of measurement to assess the extent to which 241 undergraduate students perceive the risks of smoking and the OCP, separately and combined, for circulatory disease. For all three methods, respondents read each of four vignettes describing information about a woman's risk factors (with high and low levels of both OCP and smoking), and then estimated risk of circulatory disease using one of the three risk measures. The three measures produced similar ratings. Consistent with the epidemiological evidence, information about smoking had more impact on estimates of overall risk than did information about the OCP. For all three measures, responses were consistent with an additive model of risk from smoking and the OCP. This convergence of results from different methods suggests that all three methods of measurement employed, which all had a large number of response options, may be valid.

    Notes: Introduction: Dofetilide is the newest drug approved by the United States Food and Drug Administration for the treatment of patients with atrial fibrillation (AF). Few data on the efficacy and safety of dofetilide in a diverse group of patients are available. The aim of this study was to evaluate the results of dofetilide in a consecutive series of 69 patients with AF. Methods and Results: Sixty-nine patients with persistent (n = 53) or paroxysmal (n = 16) AF were administered dofetilide in-hospital. Prior to starting dofetilide, all patients had been adequately anticoagulated, and concomitant agents contraindicated in the presence of dofetilide were discontinued. Heart rhythms were monitored continuously by telemetry in all patients. The initial dose, which was determined using the Cockroft-Gault calculated creatinine clearance, was 500 μg bid, 250 μg bid, and 125 μg bid in 51, 13, and 5 patients, respectively. Reductions in subsequent dosage occurred in 12 patients, 4 for QT prolongation. Dofetilide was discontinued in-hospital in 7 patients, 2 for adverse arrhythmic events and 3 for unacceptable QT prolongation. Twenty-seven (63%) of 43 patients in AF converted spontaneously to sinus rhythm. Fifty-eight patients were discharged receiving dofetilide treatment and were followed as outpatients for 21 ± 7 months. One third of patients continued to take dofetilide at 1 year. One patient had a cardiac arrest 1 day after hospital discharge. Conclusion: Dofetilide is a well-tolerated antiarrhythmic drug with a high conversion rate of AF to sinus rhythm. One third of patients maintained sinus rhythm at 1 year. Proarrhythmia can occur and initiation of therapy must be performed in-hospital.

    Notes: Crystalline mullite was deposited by chemical vapor deposition (CVD) onto SiC/SiC composites overlaid with CVD SiC. Specimens were exposed to isothermal oxidation tests in high-pressure air + H2O at 1200°C. Unprotected CVD SiC formed silica scales with a dense amorphous inner layer and a thick, porous, outer layer of cristobalite. Thin coatings (∼2 μm) of dense CVD mullite effectively suppressed the rapid oxidation of CVD SiC. No microstructural evidence of mullite volatility was observed under these temperature, pressure, and low-flow-rate conditions. Results of this preliminary study indicate that dense, crystalline, high-purity CVD mullite is stable and protective in low-velocity, high-pressure, moisture-containing environments.

    Chronic cocaine-mediated changes in non-human primate nucleus accumbens gene expression (2001)

    Notes: Chronic cocaine use elicits changes in the pattern of gene expression within reinforcement-related, dopaminergic regions. cDNA hybridization arrays were used to illuminate cocaine-regulated genes in the nucleus accumbens (NAcc) of non-human primates (Macaca fascicularis; cynomolgus macaque), treated daily with escalating doses of cocaine over one year. Changes seen in mRNA levels by hybridization array analysis were confirmed at the level of protein (via specific immunoblots). Significantly up-regulated genes included: protein kinase A α catalytic subunit (PKAcα); cell adhesion tyrosine kinase beta (PYK2); mitogen activated protein kinase kinase 1 (MEK1); and β-catenin. While some of these changes exist in previously described cocaine-responsive models, others are novel to any model of cocaine use. All of these adaptive responses coexist within a signaling scheme that could account for known inductions of genes(e.g. fos and jun proteins, and cyclic AMP response element binding protein) previously shown to be relevant to cocaine's behavioral actions. The complete data set from this experiment has been posted to the newly created Drug and Alcohol Abuse Array Data Consortium () for mining by the general research community.

    Caspase-2 activation is redundant during seizure-induced neuronal death (2001)

    Notes: Seizure-induced neuronal death may be under the control of the caspase family of cell death proteases. We examined the role of caspase-2 in a model of focally evoked limbic seizures with continuous EEG recording. Seizures were elicited by microinjection of kainic acid into the amygdala of the rat and terminated after 40 min by diazepam. Caspase-2 was constitutively present in brain, mostly within neurons, and was detected in both cytoplasm and nucleus. Cleaved caspase-2 (12 kDa) was detected immediately following seizure termination within injured ipsilateral hippocampus, contiguous with increased Val-Asp-Val-Ala-Asp (VDVADase) activity, a putative measure of activated caspase-2. Expression of receptor interacting protein (RIP)-associated Ich-1-homologous protein with death domain (RAIDD) was increased following seizures, whereas expression of RIP and tumor necrosis factor receptor associated protein with death domain (TRADD), other components thought to be linked to the caspase-2 activation and signaling mechanism, were unchanged. Intracerebroventricular administration of z-VDVAD-fluoromethyl ketone blocked seizure-induced caspase-2 activity but did not alter caspase-8 activity and failed to affect DNA fragmentation or neuronal death. These data support activation of caspase-2 following seizures but suggest that parallel caspase pathways may circumvent deficits in caspase-2 function to complete the cell death process.

    Characterization of Copper Interactions with Alzheimer Amyloid β Peptides (2000)

    Notes: Abstract: Cu and Zn have been shown to accumulate in the brains of Alzheimer's disease patients. We have previously reported that Cu2+ and Zn2+ bind amyloid β (Aβ), explaining their enrichment in plaque pathology. Here we detail the stoichiometries and binding affinities of multiple cooperative Cu2+-binding sites on synthetic Aβ1-40 and Aβ1-42. We have developed a ligand displacement technique (competitive metal capture analysis) that uses metal-chelator complexes to evaluate metal ion binding to Aβ, a notoriously self-aggregating peptide. This analysis indicated that there is a very-high-affinity Cu2+-binding site on Aβ1-42 (log Kapp = 17.2) that mediates peptide precipitation and that the tendency of this peptide to self-aggregate in aqueous solutions is due to the presence of trace Cu2+ contamination (customarily ∼0.1 μM). In contrast, Aβ1-40 has much lower affinity for Cu2+ at this site (estimated log Kapp = 10.3), explaining why this peptide is less self-aggregating. The greater Cu2+-binding affinity of Aβ1-42 compared with Aβ1-40 is associated with significantly diminished negative cooperativity. The role of trace metal contamination in inducing Aβ precipitation was confirmed by the demonstration that Aβ peptide (10 μM) remained soluble for 5 days only in the presence of high-affinity Cu2+-selective chelators.
