    Fish assemblages were investigated in tidal-creek and seagrass habitats in the Suwannee River estuary, Florida. A total of 91,571 fish representing 43 families were collected in monthly seine samples from January 1997 to December 1999. Tidal creeks supported greater densities of fish (3.89 fish/m2; 83% of total) than did seagrass habitats (0.93 fish/m2). We identified three distinct fish assemblages in each habitat: winter−spring, summer, and fall. Pinfish (Lagodon rhomboides), pigfish (Orthopristis chrysoptera), and syngnathids characterized seagrass assemblages, whereas spot (Leiostomus xanthurus), bay anchovy (Anchoa mitchilli), silversides (Menidia spp.), mojarras (Eucinostomus spp.), and fundulids characterized tidal-creek habitats. Important recreational and commercial species such as striped mullet (Mugil cephalus) and red drum (Sciaenops ocellatus) were found primarily in tidal creeks and were among the top 13 taxa in the fish assemblages found in the tidal-creek habitats. Tidal-creek and seagrass habitats in the Suwannee River estuary were found to support diverse fish assemblages. Seasonal patterns in occurrence, which were found to be associated with recruitment of early-life-history stages, were observed for many of the fish species

    The Development of a Community Counseling Training Clinic for Latino Immigrants

    Get PDF
    Latinos are the fasting growing minority in the United States, and among the least likely to access mental health services. Two reasons cited for the significant mental health disparities in the Latino community are: a lack of culturally responsive services and a lack of culturally competent mental health professionals. This manuscript describes the development of a community counseling training clinic constructed through a partnership between a community center and a counselor education and supervision program. Process and clinical outcomes data demonstrate that the program was successful in retaining clients and students had a positive experience at the training site

    A Community-Academic Partnership to Improve Access to Healthy Foods in Low-Income Communities

    Purpose: Access to healthy foods is often limited in low-income communities and prevents the adoption of a healthy diet needed to meet national dietary recommendations, reduce chronic disease, and prevent obesity. The Healthy Harvest Community Gardening Partnership is a community-based participatory research program between faith-based organizations, academic institutions, local philanthropy, and other non-profit institutions, created in 2009 for improving access to healthy foods and quality of life through a community garden network. Methods: Healthy Harvest uses a social ecological framework combining individual, interpersonal, and community level influences into a single program, and employs a train-the-trainer approach for providing expertise in gardening and community-capacity building to low-income, predominately African American communities. Results: To date, garden sites have been constructed at 4 churches (average church size N=353, 98% African American) and one school (287 students, 98% African American) in an inner city, low-income community. Liaisons from each garden site have attended six monthly trainings on gardening and community-capacity building. Monthly evaluations of gardening activity indicate that a total of 139 individual garden plots have been constructed of which 101 show signs of use, 79 have visible plants, 31 have visible produce of which approximately 300 lbs have been donated to local food pantries. A total of 53 community garden volunteer workdays have been conducted with over 90 volunteers participating in garden maintenance and community outreach. Initial data demonstrate the feasibility of this approach for increasing access to fruits and vegetables in low-income communities. Qualitative data is being collected to evaluate the effect of Healthy Harvest on lifestyle (physical activity and diet) and social (perceptions of neighborhood, feelings of connectedness) variables. Furthermore, Healthy Harvest plans to develop a system for distributing produce, therefore providing access to healthy foods on a broader scale. Conclusions: Overall, this novel community-academic partnership has demonstrated initial feasibility to improve access to healthy foods in low-income communities and could provide a model for other communities to prevent obesity

    Bodyweight Perceptions among Texas Women: The Effects of Religion, Race/Ethnicity, and Citizenship Status

    Despite previous work exploring linkages between religious participation and health, little research has looked at the role of religion in affecting bodyweight perceptions. Using the theoretical model developed by Levin et al. (Sociol Q 36(1):157–173, 1995) on the multidimensionality of religious participation, we develop several hypotheses and test them by using data from the 2004 Survey of Texas Adults. We estimate multinomial logistic regression models to determine the relative risk of women perceiving themselves as overweight. Results indicate that religious attendance lowers risk of women perceiving themselves as very overweight. Citizenship status was an important factor for Latinas, with noncitizens being less likely to see themselves as overweight. We also test interaction effects between religion and race. Religious attendance and prayer have a moderating effect among Latina non-citizens so that among these women, attendance and prayer intensify perceptions of feeling less overweight when compared to their white counterparts. Among African American women, the effect of increased church attendance leads to perceptions of being overweight. Prayer is also a correlate of overweight perceptions but only among African American women. We close with a discussion that highlights key implications from our findings, note study limitations, and several promising avenues for future research

    Health and Disease—Emergent States Resulting From Adaptive Social and Biological Network Interactions

    Health is an adaptive state unique to each person. This subjective state must be distinguished from the objective state of disease. The experience of health and illness (or poor health) can occur both in the absence and presence of objective disease. Given that the subjective experience of health, as well as the finding of objective disease in the community, follow a Pareto distribution, the following questions arise: What are the processes that allow the emergence of four observable states—(1) subjective health in the absence of objective disease, (2) subjective health in the presence of objective disease, (3) illness in the absence of objective disease, and (4) illness in the presence of objective disease? If we consider each individual as a unique biological system, these four health states must emerge from physiological network structures and personal behaviors. The underlying physiological mechanisms primarily arise from the dynamics of external environmental and internal patho/physiological stimuli, which activate regulatory systems including the hypothalamic-pituitary-adrenal axis and autonomic nervous system. Together with other systems, they enable feedback interactions between all of the person's system domains and impact on his system's entropy. These interactions affect individual behaviors, emotional, and cognitive responses, as well as molecular, cellular, and organ system level functions. This paper explores the hypothesis that health is an emergent state that arises from hierarchical network interactions between a person's external environment and internal physiology. As a result, the concept of health synthesizes available qualitative and quantitative evidence of interdependencies and constraints that indicate its top-down and bottom-up causative mechanisms. Thus, to provide effective care, we must use strategies that combine person-centeredness with the scientific approaches that address the molecular network physiology, which together underpin health and disease. Moreover, we propose that good health can also be promoted by strengthening resilience and self-efficacy at the personal and social level, and via cohesion at the population level. Understanding health as a state that is both individualized and that emerges from multi-scale interdependencies between microlevel physiological mechanisms of health and disease and macrolevel societal domains may provide the basis for a new public discourse for health service and health system redesign

    Orai/CRACM1 and KCa3.1 ion channels interact

    Get PDF
    open access articleBACKGROUND: Orai/CRACM1 ion channels provide the major Ca(2+) influx pathway for FcεRI-dependent human lung mast cell (HLMC) mediator release. The Ca(2+)-activated K(+) channel KCa3.1 modulates Ca(2+) influx and the secretory response through hyperpolarisation of the plasma membrane. We hypothesised that there is a close functional and spatiotemporal interaction between these Ca(2+)- and K(+)-selective channels. RESULTS: Activation of FcεRI-dependent HLMC KCa3.1 currents was dependent on the presence of extracellular Ca(2+), and attenuated in the presence of the selective Orai blocker GSK-7975A. Currents elicited by the KCa3.1 opener 1-EBIO were also attenuated by GSK-7975A. The Orai1 E106Q dominant-negative mutant ablated 1-EBIO and FcεRI-dependent KCa3.1 currents in HLMCs. Orai1 but not Orai2 was shown to co-immunoprecipitate with KCa3.1 when overexpressed in HEK293 cells, and Orai1 and KCa3.1 were seen to co-localise in the HEK293 plasma membrane using confocal microscopy. CONCLUSION: KCa3.1 activation in HLMCs is highly dependent on Ca(2+) influx through Orai1 channels, mediated via a close spatiotemporal interaction between the two channels
