Genetic parameters for degree of kyphosis were estimated from a Duroc-Landrace F(2) population (n = 316) and from a composite population (line C) composed of Duroc, Large White, and 2 sources of Landrace (n = 1,552). Live presentation did not indicate kyphosis in pigs or sows. Degree of kyphosis was measured by scoring the shape of the vertebral column of split carcasses on a scale from 0 (norm...

OBJECTIVE To estimate how axial rotation of lumbar vertebrae quantitatively affects bone mineral density, as measured by dual energy X-ray absorptiometry in the anteroposterior plane. DESIGN Observational study. SETTING University teaching hospital, Hong Kong. PATIENTS Cadaver lumbar vertebrae (L2 to L4) were removed from four adults. MAIN OUTCOME MEASURES Using dual energy X-ray absorp...

BACKGROUND In osteoporotic patients, inferior mandibular cortex undergoes resorption which its manifestations can be detected on dental panoramic radiographs as a simple and available method. The aim of this study was to evaluate the correlation between width and morphology of mandibular inferior cortex in digital panoramic radiography and postmenopausal osteoporosis. METHODS Bone mineral den...

It is important to assess the general bone condition in dental implant treatment. The relationships between the bone mineral densities (BMDs) of lumbar vertebrae and mandibular cortical bone condition in the inferior border using multi-slice computed tomography (CT) were assessed in postmenopausal women. If a strong correlation between them is obtained, the mandibular cortical bone condition ma...

Presacral vertebrae, excluding the atlas and axis, obtained from fifty dried vertebral columns were carefully examined to detect the muscular tubercles derived from the attachments of the paravertebral muscles. On the basis of the divisions of these muscles, the tubercles may be classified as follows : (1) tubercles of the median attachments of the back muscles observed at the tips of the spine...

The purpose of this study was to draw attention the number lumbar vertebrae in BA B1 crosses (Bafra×F1 (Bafra×Akkaraman)) lambs (75% Bafra and 25% Akkaraman), effect 7 on some carcass traits. Even though studies reported that might be considerably different dependent sheep genotype, has not been for Turkish breeds. While a performed, seven have identified four eighteen lambs. means length (80.8...

Introduction: While there have been numerous studies demonstrating the effect of bisphosphonates in rats as either a preventative treatment or recovering treatment for osteoporosis, few have directly compared the two treatment alternatives with respect to their effects on bone microstructure and strength. This paper, then, investigates the effects of treatment timing using Zoledronate [ZOL], a ...

Current vertebral fracture prevention measures use Dual-energy X-ray Absorptiometry (DXA) to quantify the density of the vertebrae and subsequently determine the risk of fracture. This modality however only provides information about the projected Bone Mineral Density (BMD) while the shape and spatial distribution of the bone determines the strength of the vertebrae. Quantitative Computed Tomog...

OBJECTIVE The semi-quantitative method of bone scintigraphy [bone to soft tissue (B/ST) ratio] has been used in diagnosing and evaluating systemic metabolic bone diseases. The aim of this study is to evaluate of the therapeutic effect of secondary hyperparathyroidism (SHP). METHODS The subjects were ten hemodialysis patients with SHP. Seven patients underwent parathyroidectomy (PTX), and 22-O...
