WELCOME TO iPAD

The internet Primate Aging Database (iPAD) is a multi-centered, relational database of biological variables in aging, captive nonhuman primates. Through joint initiative of the National Institute on Aging (intramural and extramural programs), National Center for Research Resources (NCRR), and the National Primate Research Center at the University of Wisconsin-Madison (WNPRC), we have organized a database to study biomarkers of aging in nonhuman primates. iPAD also provides an invaluable veterinary and clinical resource, and can generate normative data for numbers of animals across research settings. iPAD now contains over 1,000,000 data points for body weight, blood chemistry and hematology, for healthy, non-experimental subjects across time.

Many blood variables that are obtained for a routine clinical screen (e.g., differential WBC, RBC, hematocrit, hemoglobin, mean corpuscular volume, etc.) are currently found in iPAD. We also have blood chemistry data (e.g., albumin, total proteins, glucose, etc.), as well as body weights and blood pressure data. The database consists of both cross-sectional and longitudinal data with age for a variety of non-human primate species.

The iPAD contains data from a number of different primate research facilities, and therefore pooled data across sites may represent different housing conditions, diets, and assay procedures. All subjects were control animals (i.e., non-experimental) and deemed healthy at the time of measurement. Data values for each age represent a mean of the measures for an individual subject for a three-month period.

iPAD-users are cautioned that all data in the database may not be normally-distributed, may be unbalanced (in terms of facilities and across individual subjects) and also may represent repeated measures on individual subjects across time. Statistical analyses should be undertaken at user discretion.
