Objective: In this report, we used a qualitative descriptive design to explore young African American adults' intergenerationally influenced strategies to experienced racial discrimination., Methods: The study was guided by a qualitative descriptive design using criterion and snowball sampling, and semi-structured interview questions. We also explored, quantitatively, gender differences among the racial discrimination experiences encountered and the strategies used., Findings: Forty-nine participants included in this report were an average age of 29.5 (SD = 10.1). Racial discrimination experiences included daily microaggressions such as insensitive comments, stereotyping, exclusion from work and school activities, perceived low expectations, inequities in employment, and police profiling. Intergenerationally influenced strategies used in response to these experiences included religious beliefs and practices, positive reframing, and modeling behaviors used by previous generations. These intergenerationally influenced strategies enabled participants to remain calm, to express goodwill toward others, and to be patient and hopeful for a better future., Conclusion: Since intergenerationally influenced strategies are likely potential sources of strength and resilience for young African Americans, knowledge of these strategies might be useful to health care practitioners seeking to improve the mental health care of this population., (Copyright © 2020 National Medical Association.

Objective: The purpose of this study was to explore whether a particular combination of individual characteristics influences patient satisfaction with the health care system among a sample of African American men in North Carolina with prostate cancer. Patient satisfaction may be relevant for improving African American men's use of regular care, thus improving the early detection of prostate cancer and attenuating racial disparities in prostate cancer outcomes., Methods: This descriptive correlation study examined relationships of individual characteristics that influence patient satisfaction using data from 505 African American men from North Carolina, who prospectively enrolled in the North Carolina-Louisiana Prostate Cancer Project from September 2004 to November 2007. Analyses consisted of univariate statistics, bivariate analysis, and multiple regression analysis., Results: The variables selected for the final model were: participation in religious activities, mistrust, racism, and perceived access to care. In this study, both cultural variables, mistrust (p=<.0001, F=95.58) and racism (p=<.002, F=5.59), were significantly negatively associated with patient satisfaction and accounted for the majority of the variability represented by individual characteristics., Conclusion: Mistrust and racism are cultural factors that are extremely important and have been negatively associated with patient satisfaction and decreased desires to utilize health care services for African American men. To overcome barriers in seeking health care services, health care providers need to implement a patient-centered approach by creating a clinical environment that demonstrates cultural competence and eliminating policies, procedures, processes, or personnel that foster mistrust and racism.

Normal ageing-associated spatial memory impairment has been linked to subtle changes in the hippocampal network. Here we test whether the age-dependent reduction in gamma oscillations can be explained by the changes in intrinsic properties of hippocampal interneurons. Kainate-induced gamma oscillations, but not spontaneous gamma oscillations, were reduced in slices from aged mice. CA3 interneurons were recorded in slices from young and aged mice using Fura-2-filled pipettes. Passive membrane properties, firing properties, medium- and slow-afterhyperpolarisation amplitudes, basal [Ca(2+)](i) and firing-induced [Ca(2+)](i) transients were not different with ageing. Kainate caused a larger depolarisation and increase in [Ca(2+)](i) signal in aged interneurons than in young ones. In contrast to young interneurons, kainate increased the medium- and slow-afterhyperpolarisation and underlying [Ca(2+)](i) transient in aged interneurons. Modulating the slow-afterhyperpolarisation by modulating L-type calcium channels with BAY K 8644 and nimodipine suppressed and potentiated, respectively, kainate-induced gamma oscillations in young slices. The age-dependent and stimulation-dependent increase in basal [Ca(2+)](i), firing-induced [Ca(2+)](i) transient and associated afterhyperpolarisation may reduce interneuron excitability and contribute to an age-dependent impairment of hippocampal gamma oscillations., (Copyright © 2009 Elsevier Inc.

Context: Cancer survivors use distinct sets of coping behaviors that vary in their associations with psychological health and quality of life. However, existing research has largely focused on Caucasian and middle-class subjects., Objectives: This study explores whether clusters with differing coping profiles could be identified among older African American cancer survivors and whether these profiles varied on cultural factors and physical, psychological, and relationship well-being., Methods: Four hundred forty-nine older African American cancer survivors recruited from outpatient oncology clinics completed a questionnaire booklet containing the Ways of Helping Questionnaire (WHQ), the Brief Index of Race-Related Stress, the Religious Involvement Scale, Mutuality Scale, and the Short Form-12 Health Survey Questionnaire. A k-means cluster analysis was conducted using the WHQ., Results: Four distinct coping profiles were identified and labeled as high coping, low encouraging healthy behaviors, low coping, and strong/distracting behaviors. Coping profiles were associated with participant's gender, age, and living-alone status. Controlling for these demographic differences, the coping profiles were associated with religiosity; experiences with racism; and physical, psychological, and relationship well-being., Conclusions: The findings from this study lend support for examining coping profiles and health outcomes among African American cancer survivors. This research also suggests that these profiles vary on cultural factors. This information should prove useful to researchers as they develop culturally appropriate interventions for this underserved population., (Copyright © 2011 U.S. Cancer Pain Relief Committee.

Polyglutamine (polyGln) aggregates are neuropathological markers of expanded CAG repeat disorders, and may also play a critical role in the development of these diseases. We have established a highly sensitive, fast, reproducible, and specific assay capable of monitoring aggregate-dependent deposition of polyglutamine peptides. This assay allows detailed studies on various aspects of aggregation kinetics, and also makes possible the detection and quantitation of low levels of "extension-competent" aggregates. In the simplest form of this assay, polyGln aggregates are made from chemically synthesized peptides and immobilized onto microplate wells. These wells are incubated for different times with low concentrations of a soluble biotinylated polyGln peptide. Europium-streptavidin complexation of the immobilized biotin, followed by time-resolved fluorescence detection of the deposited europium, allows us to calculate the rate (fmol/h) of incorporation of polyGln peptides into polyGln aggregates. This assay will make possible basic studies on the assembly mechanism of polyGln aggregates and on critical features of the reaction, such as polyGln length dependence. The assay also will be a valuable tool for screening and characterizing anti-aggregation inhibitors. It will also be useful for detection and quantitation of aggregation-competent polyGln aggregates in biological materials, which may prove to be of critical importance in understanding the disease mechanism., (Copyright 2001 Academic Press.)
