The wrist and hand region has been the most commonly used for estimating age and osseous development due to the great number of ossification centers. The aim was to determine which method, Tanner & Whitehouse's (TW3), Greulich & Pyle's (GP) or Eklof & Ringertz's, more closely relates to the chronological age in subjects with Down syndrome with chronological ages between 61 and 180 months, using...

This paper compares traditional averagesbased model with other various age estimation models in the range from the simplest to the advanced ones, and introduces novel Tabular Constrained Multiple-linear Regression (TCMLR) model. This TCMLR model has similar complexity as traditional averages-based model (it can by evaluated manually), but improves the mean absolute error in average about 0.30 y...

Understanding the relationship between age and work attitudes is widely recognized as crucial for organizational success (Glass, 2007; Greller & Stroh, 1995; Kanfer & Ackerman, 2004). Our need for this information is emphasized by recent demographic trends. Workers over 40 years of age currently dominate the North American workforce (Bureau of Labor Statistics, 2002; Fullerton, 1999) and labor ...

Estimates of biological age based on DNA methylation patterns, often referred to as "epigenetic age", "DNAm age", have been shown to be robust biomarkers of age in humans. We previously demonstrated that independent of chronological age, epigenetic age assessed in blood predicted all-cause mortality in four human cohorts. Here, we expanded our original observation to 13 different cohorts for a ...

The relationship between chronological age and the development of permanent teeth has been investigated according to the method described by Dcmirjian et a! . Panoramic radiographs of 1085 children (male and female) of varying ages (2 years to IS years) were evaluated. Only healthy children with full complement of permanent teeth for their chronological age were used in this study. The degree o...

The use of chronological or/and corrected age administering BSITD-III in preterm children was investigated in a sample of preterm infants and full-term infants. BSITD-III was administered at 12 months corrected age. The performance scores for the three BSITD-III subscales were calculated according to the child’ chronological age and considering the BSITD-III request for correction referring to ...

Aging is commonly accompanied by a decline in cognitive functions such as learning and memory. In social insects, aging is tightly linked to social role. The honeybee (Apis mellifera L.) offers the unique opportunity to separate chronological age from social role. In the present paper, we tested whether chronological age, social role and the duration of performing this role affect tactile learn...

OBJECTIVE To quantify the degree of perceived age change after aesthetic facial surgical procedures to provide an objective measure of surgical success. METHODS Sixty patients undergoing various aging face surgical procedures were randomly chosen for analysis. Preoperative and postoperative photographs were evaluated. Raters were presented with photographs in a random assortment and were aske...
