Human serum contains two isoforms of tartrate-resistant acid phosphatase (TRACP) known as TRACP 5a and TRACP 5b with pH optima of 5.0 and 5.8, respectively. Preliminary data suggest that serum TRACP 5b is derived from osteoclasts and serum TRACP 5a from some other cells. It has been reported that heparin inhibits TRACP 5a but has no effect on the activity(More)
Axial transmission of ultrasound along cortical bone may reflect a combination of material and structural properties of long bone cortices. The goal of this study was to determine the association of speed of sound (SOS) with cortical density (CoD), cortical wall thickness (CWT), and total cortical area (CoA). Quantitative ultrasound (QUS) and peripheral(More)
bone mineral density of the calcaneus in relation to fractures was studied both retrospectively and prospectively among the 75- and 80-year-old men and women resident in the city of Jyväskylä, Finland, in 1989 and 1990, respectively. The bone measurements were performed at the calcaneus by125I-photon absorption. Retrospective fracture (RF) history after age(More)
This study aimed to assess the factors that may influence the distribution and description of broadband ultrasound attenuation (BUA) and to identify specific criteria for diagnostic consideration when collecting BUA reference data. Two hundred Caucasian women (aged 20–79 years) without a history of atraumatic fractures or medicines known to affect bone(More)
The aim of this study was to establish a normative database, assess precision, and evaluate the ability to identify women with low bone mass and to discriminate women with fracture from those without for a highly portable, scanning calcaneal ultrasonometer: the QUS-2. Fourteen hundred and one Caucasian women were recruited for the study. Among them were 794(More)
Ehlers-Danlos Syndrome (EDS) is the most common inherited disorder of connective tissue recognized. The objectives of the present study were to determine bone mineral density (BMD) and biochemical markers of bone metabolism in EDS. Twenty-three subjects with Type III EDS and 23 matched controls underwent BMD measurement by dual-Energy X-ray absorptiometry(More)
There is little information concerning how the mutation of collagen affects bone mineralization and the assessment of bone properties. To estimate these influences, we performed ultrasonic assessments of the calcaneus and bone mineral density (BMD) measurements of the hip and lumbar spine. Females with diseases related to the mutation of collagen(More)
Objective: The present study was aimed to study the effectiveness of botulinum toxin A masseter injection and hyaluronic acid chin injection in pretext of the lower third facial contour remodeling. Methods: 60 Chinese cases that underwent a lower third of facial contour remodeling for the first time were selected. Before surgery, a conventional(More)
