We recruited 2000 men and 2000 women aged 65 years or older. Baseline BMI, waist-hip ratio (WHR), body fat index (BFI = total body fat/height square), relative truncal fat (RTF = trunk fat/total body fat), and body muscle mass index (BMMI = total body muscle mass/height square) were measured. Mortality was ascertained by death registry after 63.3 (median) months.

Two hundred and forty-two men and 78 women died. In men, mortality hazard ratio (HR) decreased consistently by 0.85 (p < .005), 0.86 (p < .005), and 0.86 (p < .005) per every quintile increase in BMI, BFI, and BMMI, respectively. A J-shaped relationship was observed in central adiposity (RTF and WHR) quintiles;

the minimum values were at the 3rd WHR quintile (0.92-0.94) and 4th RTF quintile (mean WHR, Oligomycin A cost 0.94). When RTF was tested with BFI, both high and low central adiposity were unfavorable while general adiposity became marginally insignificant (p = 0.062). When BFI and BMMI Selleckchem Verteporfin were tested together, increasing adiposity rather than muscle mass favored survival

(BFI quintile, HR 0.97, p .015; BMMI quintile, HR 1.00, p .997).

Older men were resistive to hazards of overweight and adiposity; and mild-grade overweight, obesity, and even central obesity might be protective. This may bear significant implication on the recommended cutoff values for BMI and WHR in the older population.”
“Brn-4, a member of the homeobox family of transcription factors, has previously been implicated in the regeneration and repair of denervated striatum. We investigated the

effects of Brn-4 on the differentiation and development of neural stem cells (NSCs) from E16 rat hippocampus. Dichloromethane dehalogenase Immunocytochemistry revealed that extracts of deafferented hippocampus promoted neuronal differentiation to a greater extent than extracts from normal hippocampus. Deafferented extracts also promoted maturation of newborn neurons as reflected in changes in cell areas and perimeters, and enhanced Brn-4 expression in MAP-2 positive neurons. Suppression or overexpression of Brn-4 in NSCs markedly decreased or increased neuronal differentiation and maturation of newborn neurons, respectively. These results suggest that Brn-4 expression is required both for neuronal differentiation of NSCs and maturation of newborn neurons, and that there may be some regulatory factors in deafferented hippocampus that can regulate Brn-4 expression in neuronal progenitors. Brn-4 is therefore a potential research target for the development of new therapeutics to promote brain repair. (C) 2010 Elsevier Ireland Ltd and the Japan Neuroscience Society. All rights reserved.”
“The prevalence of overweight and obesity has increased in all age groups, including older adults. However, it is not known whether higher body weight is maintained in the very old and in the years prior to death.
