The results of this study indicate that 6 weeks of voluntary alcohol intake are sufficient for the development of physical dependence upon alcohol in the alcohol-preferring P rats as measured by susceptibility to bicuculline-induced seizures. This time is much shorter than the 15-20 weeks reported earlier. Development of physical dependence to alcohol was associated with an increase in daily alcohol intake (40% over the baseline), an increase in alcohol intake during each drinking bout (90% over the baseline), and elevated anxiety during alcohol withdrawal.
CINCH (Consortium for the Immunization of Norfolk's Children) is an urban coalition that was developed in 1993 to improve childhood immunization rates in Norfolk, Virginia. CINCH involves diverse citizens and institutions in effective community-based assessment, planning, and action. A needs assessment from 1993 found that only 49% of Norfolk 2-year-olds were adequately immunized. Using this data, CINCH developed a plan focused on education and communication, support for at-risk families, increased access to immunizations, and improved immunization delivery. After federal funding ended in 1995, members voted to expand the scope of the coalition to address additional child health needs and to broaden the membership. CINCH is a model for a sustainable city-citizen learning environment that intervenes to "help families help themselves to better health." The coalition is presented as an organization that focuses on community empowerment and development. The stages of coalition development and implications for coalition implementation in other sites are discussed.
A strong association has been observed between [3H]zolpidem binding and the presence of gamma-aminobutyric acid (GABAA) receptor mRNA for alpha 1-, beta 2-, and gamma 2-subunits in specific brain regions. This correlates with observed sensitivity of individual neurons to zolpidem and ethanol in these same regions. Previous studies using homogenate binding approaches showed small alterations in [3H]zolpidem binding levels after chronic ethanol exposure. This study was undertaken to ascertain if there is regional specificity of the effects of chronic ethanol administration on [3H]zolpidem binding levels. Chronic ethanol administration induced small, but significant alterations in [3H]zolpidem (5 nM) binding in the inferior colliculus, substantia nigra, and the medial septum. [3H]Zolpidem binding was increased in the inferior colliculus and substantia nigra, and decreased in the medial septum. No significant differences in [3H]zolpidem binding were noted in any other brain area analyzed, including the cortex and cerebellum. These findings show that chronic ethanol administration has small effects on [3H]zolpidem binding, although they occur in a site-specific and bidirectional manner. Moreover, there is no correlation between changes in [3H]zolpidem binding and alterations in GABAA receptor subunit expression.
Coalition development is a major strategy to increase immunization rates. However, if local and state coalitions are to succeed, their staffs need training and technical assistance in coalition development, community planning, and program implementation. The National Coalition Training Institute trains key health agency staff in 87 state, territorial, and urban sites to perform needs assessments, use data to guide planning, plan comprehensive strategies, and evaluate their coalitions. The curriculum is based on training needs that are identified by a national survey of immunization coalitions, effective approaches, and participant evaluation. According to evaluations conducted during its first year, the National Coalition Training Institute is meeting the needs of participants.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
