The results from studies on potential treatment effects of acupuncture are often limited due to serious difficulties in methodology. Randomized controlled trials on acupuncture should test a widely accepted treatment strategy of verum and sham acupuncture. However, in clinical practice various patterns of acupuncture techniques are employed, and up to now no generally accepted guidelines on how to perform a reliable verum or sham treatment have been established.

Caloric restriction (CR), a reduction of food intake while avoiding malnutrition, can delay the onset of cancer and age-related diseases in several species, including mice. In addition, depending of the genetic background, CR can also increase or decrease mouse longevity. This has highlighted the importance of identifying the molecular pathways that interplay with CR in modulating longevity. Significant lifespan extension in mice has been recently achieved through over-expression of the catalytic subunit of mouse telomerase (mTERT) in a cancer protective background.

BACKGROUND: A longitudinal repeated measures design over pregnancy and post-birth, with a control group would provide insight into the mechanical adaptations of the body under conditions of changing load during a common female human lifespan condition, while minimizing the influences of inter human differences.

OBJECTIVE: To examine the relative risk and population attributable risk (PAR) of death with dementia of varying type and severity and other risk factors in a population of exceptional longevity. METHODS: Deaths were monitored over 5 years using vital statistics records and newspaper obituaries in 355 individuals with prevalent dementia and 4,328 without in Cache County, UT. Mean age was 83.3 (SD 7.0) years with dementia and 73.7 (SD 6.8) years without. History of coronary artery disease, hypertension, diabetes, and other life-shortening illness was ascertained from interviews.

Exceptional survival results from complicated interplay between genetic and environmental factors. The effects of these factors on survival are mediated by the biological and physiological variables, which affect mortality risk. In this paper, we evaluated the role of blood glucose (BG) in exceptional survival using the Framingham heart study data for the main (FHS) and offspring (FHSO) cohorts.

BACKGROUND: Physical activity is associated with reduced risks of chronic diseases and premature death. Whether physical activity is also associated with improved overall health among those who survive to older ages is unclear. METHODS: A total of 13,535 Nurses' Health Study participants who were free of major chronic diseases at baseline in 1986 and had survived to age 70 years or older as of the 1995-2001 period made up the study population.

OBJECTIVES: To determine whether offspring of parents with exceptional longevity (OPEL) have a lower rate of dementia than offspring of parents with usual survival (OPUS). DESIGN: Community-based prospective cohort study. SETTING: Bronx, New York. PARTICIPANTS: A volunteer sample of 424 community-residing older adults without dementia aged 75 to 85 recruited from Bronx County starting in 1980 and followed for up to 23 years. MEASUREMENTS: Epidemiological, clinical, and neuropsychological assessments were completed every 12 to 18 months.

CONTEXT: Few studies have examined whether the inflammatory markers IL-6 and C-reactive protein (CRP) are associated with exceptional longevity. OBJECTIVE: Our objective was to determine the association of serum CRP and IL-6 with adult lifespan. DESIGN, SETTING, AND PARTICIPANTS: This was a prospective, population-based study of 610 men and 743 postmenopausal women, mean age 73 yr, who had serum IL-6 and CRP measurements at baseline (1984-1987) and who were followed for mortality for up to 23 yr (through 2008).

OBJECTIVES: To characterize the social characteristics and physical, functional, mental, and cognitive health of exceptional survivors in the United States and how the experience of exceptional longevity differs according to social status. DESIGN: Nationally representative longitudinal study of older Americans. SETTING: United States. PARTICIPANTS: One thousand six hundred forty-nine men and women born from 1900 to 1911 from the Health and Retirement Study: 1,424 nonsurvivors who died before reaching the age of 97 and 225 exceptional survivors who survived to age 97 and older.

Atrophy is one of the major age-related changes in the brain. The absence of brain atrophy in elderly individuals reflects deceleration in the process of biological aging. Moreover, results from human twin studies suggest a large genetic influence on the variance of human brain tissue volumes. To investigate the association of brain volumes with exceptional longevity, we tested whether middle-aged to elderly offspring of nonagenarian siblings have larger brain volumes than their spouses using magnetic resonance imaging.
