BACKGROUND: Scientific interest in acupuncture has led numerous investigators to conduct clinical trials to test the efficacy of acupuncture for various conditions, but the mechanisms underlying acupuncture are poorly understood. METHODS: The author conducted a PubMed search to obtain a fair sample of acupuncture clinical trials published in English in 2005. Each article was reviewed for a physiologic rationale, as well as study objectives and outcomes, experimental and control interventions, country of origin, funding sources and journal type.
High prevalence and low female/male ratio for validated centenarians are observed in Sardinia and these findings appear to be thus far unique to this island. Moreover a specific region on the island is characterized by exceptional male longevity. We calculated the extreme longevity index (ELI), defined as the percentage of persons born in Sardinia between 1880 and 1900, who became centenarians.

To explore factors associated with longevity, we studied geographic distribution of centenarians in Japan, based on 1990 the population census. We calculated the proportion of centenarians from ratio of number of centenarian to that of population aged 65 years or older. Centenarians in Japan consisted of number 4,152 persons. By prefecture, Tokyo had the most centenarians (383), followed by Okinawa (193) and Fukuoka (151) prefectures. Fukui had the least (24), followed by Akita (26) and Ishikawa (29) prefectures.
Community activists in Chicago believed their neighborhoods were being targeted by alcohol and tobacco outdoor advertisers, despite the Outdoor Advertising Association of America's voluntary code of principles, which claims to restrict the placement of ads for age-restricted products and prevent billboard saturation of urban neighborhoods. A research and action plan resulted from a 10-year collaborative partnership among Loyola University Chicago, the American Lung Association of Metropolitan Chicago (ALAMC), and community activists from a predominately African American church, St.
BACKGROUND: Lithium as a substance occurring naturally in food and drinking water may exert positive effects on mental health. In therapeutic doses, which are more than 100 times higher than natural daily intakes, lithium has been proven to be a mood-stabilizer and suicide preventive. This study examined whether natural lithium content in drinking water is regionally associated with lower suicide rates. METHODS: Previous statistical approaches were challenged by global and local spatial regression models taking spatial autocorrelation as well as non-stationarity into account.
The authors examined the degree to which ratings of negative affectivity (NA) and relational security predicted the breakup of long-distance and same-city dating relationships. Couples completed initial surveys and were contacted 1 year later about the status of their relationship. In the initial surveys, both partners completed NA and relational security assessments. Overall, both the NA and relational security of men and women predicted stability. However, as predicted, structural equation modeling revealed a gender difference in the interaction between NA and long-distance status.
OBJECTIVE: Previous studies suggest that unemployment predicts increased cardiovascular disease (CVD) risk, but whether unemployment insurance programs mitigate this risk has not been assessed. Exploiting US state variations in unemployment insurance benefit programs, we tested the hypothesis that more generous benefits reduce CVD risk. METHODS: Cohort data came from 16,108 participants in the Health and Retirement Study (HRS) aged 50-65 at baseline interviewed from 1992 to 2010.
In an inclusive fitness model of social behaviour, a key concept is that of the relatedness between two interactants. This is typically calculated with reference to a "focal" actor taken to be representative of all actors, but when there are different interaction configurations, relatedness must be constructed as an average over all such configurations. We provide an example of such a calculation in an island model with local reproduction but global mortality, leading to variable island size and hence variable numbers of individual interactions.
