An analysis of serial skeletal ages assessed by the methods of Greulich and Pyle and Tanner and Whitehouse has shown that the errors of prediction are less for the Greulich-Pyle method than for that of Tanner and Whitehouse. Furthermore, when predictions are made by rectilinear extrapolation from serial skeletal ages, the errors are larger than those ...

Frontiers in Bioscience, 2001
Age-related changes in muscle mass (sarcopenia) and functional properties are the result of a very complex hierarchical system of basic cell aging processes and cell adaptive responses. A basic aging mechanism pertains to mitochondrial production of free radicals and their associated secondary effects.

Proteomics of skeletal muscle aging
PROTEOMICS, 2009Abstract Extended human longevity has resulted in increasing numbers of elderly persons in the general population. However, old age is also associated with a variety of serious physical disorders. Frailty among sedentary elderly patients is related to the impaired structure and function of contractile fibers. Biochemical research into

The Microcirculation of Skeletal Muscle in Aging
Microcirculation, 2006ABSTRACTMicrovascular structure and function are key aspects of tissue and organ health. At approximately 40% of total body mass, skeletal muscle contains more microvessels than any other organ system in the body. Moreover, skeletal muscle is the most dynamic tissue in the body with the capacity to increase blood flow and metabolic rate 30‐ to 50‐ fold.

Clinical Pediatrics, 1962
The uniqueness of the individual child is a biological fact that is readily recognized by students of child development. The applications of concepts based upon this realization involves the use of methods and technics which allow for the expression of this individuality.

Skeletal muscle proteolysis in aging
Current Opinion in Clinical Nutrition & Metabolic Care, 2009To understand age-related changes in proteolysis and apoptosis in skeletal muscle in relation to oxidative stress and mitochondrial alterations.During aging, a progressive loss of muscle mass (sarcopenia) has been described in both human and rodents.

Skeletal Age and Age Verification in YouthSport
Sports Medicine, 2011Problems with accurate chronological age (CA) reporting occur on a more or less regular basis in youth sports. As a result, there is increasing discussion of age verification. Use of 'bone age' or skeletal age (SA) for the purpose of estimating or verifying CA has been used in medicolegal contexts for many years and also in youth sport competitions ...

Reviews in Clinical Gerontology, 2007
Average world life expectancy has seen a dramatic rise over the last two centuries although active life expectancy remains relatively unchanged. One reason for this is that aging results in skeletal muscle becoming smaller, weaker and more susceptible to contraction-induced injury.

Skeletal Implications of Reproductive Aging
Seminars in Reproductive Medicine, 2010The skeleton's density (mineral content and strength) is due to genetics (~60%), nutrition (~20%), and sex hormones (20%). The last factor increases bone density at puberty, mostly due to estrogen production. During reproductive aging as the ovaries lose most of their follicles, estrogen production declines.

Clinical calcium, 2013
Skeletal aging means aging of calcified bone matrix. Although calcification is an essential part of bone formation and its strength, in case of calcium deficiency, calcium is mobilized from bone at the expense of skeletal integrity. The quality as well as quantity of bone matrix is maintained through remodeling activity collaboratively performed by ...
