Subjects were compared on the basis of chronological age as well as by Tanner stage to correct for potential differences in the timing of puberty. Habitual dietary intake and physical activity were also assessed and corGraceDepartmentS.Department...
Changes With Age: Older Tissue Loses Osteocyte Sensitivity to Microdamage Due to continual remodeling throughout life, regions of bone tissue vary in tissue age and do not match the chronological age of an individual. However, interstitial regions that do persist for decades will eventually lose os...
Mesenchymal stem cells promising role in cell-based therapies and tissue engineering appears to be limited due to a decline of their regenerative potential with increasing donor age. Six age groups from bone marrow mesenchymal stem cells of Wistar rats w
Table 2 Spearman correlation coefficients (r′) obtained between chronological age, elastic coefficients, elastic modus and ration of immature/mature cross-links, and the different parameters of the microstructure analysis obtained by μCT (*p< 0.05, #p< 0.01, Juv. represents the juvenile group). ...
Additional chronological control is provided by two known‐age volcanic tephras at the Hukanui sites in the North Island. At the South Island site (Earthquakes #1), an infilled burrow provides independent age control, in that fossils inside the burrow should yield younger ages than the sediments...
Donor age and long-term culture affect differentiation and proliferation of human bone marrow mesenchymal stem cells. "chondrogenic potential did not change [with aging]" The growth of adult(25-50) MSCs was only slightly than child MSCS(0-12) but old had significantly less growth of MSCs. ...

Some of us even look older than our chronological age due to genetics, health conditions, smoking, excessive drinking or repeated unprotected sun damage. Whatever your reason for wanting to look younger, Advanced Aesthetics Las Vegas in Las Vegas, ASA can help...
Results Subjects characterization. The mean chronological age of AIS and Con subjects were 14.8 ± 1.89 and 14.5 ± 4.13 years old, respectively. There was no significant difference between AIS and Con in all the demo- graphic and anthropometric parameters, and femoral ...
carbonation was lower in both tissue regions in the juvenile group as compared to the adult group. Indeed, carbonation was always lower in interstitial bone than in osteonal bone. We conclude that carbonate-incorporation in bone matrix is different based on chronological age and tissue age (“yo...
