Many studies of aging examine biomarkers one at a time, but complex systems theory and network theory suggest that interpretations of individual markers may be context-dependent. Here, we attempted to detect underlying processes governing the levels of many biomarkers simultaneously by applying principal components analysis to 43 common clinical biomarkers(More)
Chromosome dimers, which form during the bacterial life cycle, represent a problem that must be solved by the bacterial cell machinery so that chromosome segregation can occur effectively. The Xer/dif site-specific recombination system, utilized by most bacteria, resolves chromosome dimers into monomers using two tyrosine recombinases, XerC and XerD, to(More)
XerC and XerD are members of the tyrosine recombinase family and mediate site-specific recombination that contributes to the stability of circular chromosomes in bacteria by resolving plasmid multimers and chromosome dimers to monomers prior to cell division. Homologues of xerC/xerD genes have been found in many bacteria, and in the lactococci and(More)
Physiological dysregulation may underlie aging and many chronic diseases, but is challenging to quantify because of the complexity of the underlying systems. Recently, we described a measure of physiological dysregulation, DM, that uses statistical distance to assess the degree to which an individual's biomarker profile is normal versus aberrant. However,(More)
