A new six-parameter two-phase nonlinear growth and decline model is fitted to cross-sectional data on human stature and brain weight obtained from autopsies in Germany at the end of the 19th century. Brain growth may have ended at a total a...

The description of relative growth in the limb bones of Arikara Indians from a large archeological sample (N = 412 nonadults) is approached by (1) using a multivariate generalization of the bivariate scaling relationship, and (2) extracting...
Modification of hypothalamic content of growth hormone regulatory peptides in maternally deprived neonatal rats [0.03%]

The possibility that maternal deprivation (MD) modifies growth hormone releasing hormone (GHRH) and/or growth hormone release inhibiting hormone (GHRIH) in 10-day-old rat pups was investigated by quantifying the total hypothalamic content o...

In this paper, we shall attempt to quantify the rather abstractly and ambiguously used concepts of acceleration of aging and rate or velocity of aging. The use of the phrase "rate of aging", in the gerontological literature, requires that w...
A nonparametric comparison of monomolecular growth curves: application to western painted turtle data [0.03%]

Intractable distributional assumptions are generated in parametric analyses comparing groups of subjects described by nonlinear growth models. The distributional situation becomes more complex when pointwise mean curves best describe group ...

Unilateral cataracts were investigated in 750 day-old BALB/c, C57BL/6 and DBA/2 mice, and the six reciprocal crosses between these strains. This abnormality of the lens appears to be inherited additively in the cross DBA/2xBALB/c (with inco...

Previous studies support the existence of a central set point for target body size. The set point is a hypothetical fixed reference for body size. The present experiments were carried out to determine whether target body size and, by implic...

In this paper we propose a mathematical model for the growth of solid tumors which employs quiescence as a mechanism to explain characteristic Gompertz-type growth curves. The model distinguishes between two types of cells within the tumor,...
