Available techniques for determining age from human cranial remains are limited. This study examines the efficacy of Meindl and Lovejoy's (1985) method of determining age based on ectocranial suture closure patterns as compared to a baselin...
Regional differences in D/L aspartic acid ratios in the human mandible as a possible indicator of the bone remodeling rate [0.03%]
人下颌骨D/L天冬氨酸比率的地区差异及其作为骨重塑率指示剂的可能性

Susumu Ohtani et al.
In slowly metabolizing tissue such as tooth, bone and ocular lens, D-amino acids converted from L-amino acids accumulate with age and thus reflect the tissue turnover rate. To investigate whether D-amino acids play a role in determining the...
Effects of 2,3,7,8-tetrachlorodibenzo-p-dioxin on molar development among non-resistant inbred strains of mice: a geometric morphometric analysis [0.03%]

Prenatal development is highly sensitive to the effects of environmental contaminants. 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is an environmental toxicant that at very low levels causes teratogenic effects such as irregular tooth develo...
In vivo evaluation of changes in body composition of transgenic mice expressing the myostatin pro domain using dual energy X-ray absorptiometry [0.03%]
双能X线吸收法检测肌生长抑素蛋白质调节转基因小鼠体内体成分的变化

Over expression of the pro domain of myostatin (MLC-pro) interferes with myostatin function, thus promoting muscle growth. The purpose of this study was to use dual energy X-ray absorptiometry (DXA) to monitor, in vivo, the course of change...

Although recent endeavors to discover the mechanisms of the aging process have been numerous and successful, there is still much to be learned. Genes implicated in the aging process were mapped to the canine genome and will serve as additio...
Catch-up in body weight of intrauterine growth retarded (IUGR) rats castrated and treated with growth hormone [0.03%]
