Grasping is one of a few adaptive mechanisms that, in conjunction with clinging, hooking, arm swinging, adhering, and flying, allowed for incursion into the arboreal eco-space. Little research has been done that addresses grasping as an enhanced manual ability in non-mammalian tetrapods, with the exception of studies comparing the anatomy of muscle and tendon structure. Previous studies showed ...

Abstract Background Ultrasound-guided lumbar pain interventions were thought to be difficult; the high acoustic impedance of bone hides underling structures and needle path. Reviewing sonoanatomy region using different planes angles made better sonographic guidance for spine injections. The aim this prospective study is assess accuracy safety ultrasound (US)-guided trans-foraminal pulsed radiof...

The anatomy of the autonomic sympathetic vasomotor nerve supply of bone was studied in rabbits by methods of histochemistry, and fluorescent and electron microscopy. Our observations show that the intraosseous vessels are richly supplied by adrenergic nerves. The large primary nerves are located on or about the surface of the vessel; the medium sized secondary nerves spiral around the long axis...

accurate measurements of physical characteristics of bone are essential for diagnosis, assessment of change following treatment, and therefore, indirectly, for evaluation of new forms of therapy. this is particularly true of osteoporosis and aging skeleton, in which fractures occur easily. methods: in this study an ultrasonic system was set-up and calibrated on plexiglas tubes of variable thick...

objective(s):various methods for repairing bone defects are presented. cell therapy is one of these methods. bone marrow stromal cells (bmscs) seem to be suitable for this purpose. on the other hand, lots of biomaterials are used to improve and repair the defect in the body, so in this study we tried to produce a similar structure to the bone by the chitosan and hydroxyapatite. materials and me...

Pseudo hypoparathyroidism is a hereditary disorder characterized by symptoms and signs of hypoparathyroidism, typically in association with distinctive skeletal developmental defects. The due to deficient end organ response parathyroid hormone. We describe 26-year-old woman who has typical features Albright's osteodystrophy. Which include round face, short neck stature brachydactyly. Laboratory...

Background: Osteoporosis is a systemic skeletal disease characterized by low bone mineral density (BMD) and micro-architectural deterioration of bone tissue, leading to bone fragility and increased fracture risk. Since Panoramic image is a feasible and relatively routine imaging technique in dentistry; it could provide an opportunistic chance for screening osteoporosis. In this regard, numerous...
