BACKGROUND Low back pain is a disabling and common condition, whose etiology often remains unknown. A suggested, however rarely considered, cause is neuropathy of the medial branch of the superior cluneal nerves (mSCN)-either at the level of the originating roots or at the point where it crosses the iliac crest, where it is ensheathed by an osseo-ligamentous tunnel. Diagnosis and treatment have...

OBJECTIVES To utilize single photon emission computerized tomography performed in sequence to determine the osseo-integrating capabilities and osteoblastic activities of a new bone regeneration technique called the membrane--sandwich technique (Ogunsalu sandwich bone regenerating technique) and to compare the quality and quantity of bone formed by this bone regeneration unit to bone regeneratio...

BACKGROUND Finger amputation may result from congenital cause, trauma, infection and tumours. The finger amputation may be rehabilitated with dental implant-retained finger prosthesis. The success of implant-retained finger prosthesis is determined by the implant loading. The type of the force is a determining factor in implant loading. OBJECTIVE To evaluate stress distributions in finger bon...

A variety of conditions may lead to arthritis of the hip during adolescence. Although uncommon, total hip arthroplasty may occasionally be necessary for treatment of end-stage disabling arthritis of the hip in the young. There is paucity of information documenting the outcome of uncemented total hip arthroplasty in adolescents. We report our experience with total hip arthroplasty in patients un...

Bone loss in the oral and maxillofacial region caused by trauma, tumors, congenital disorders, or degenerative diseases is a health care problem worldwide. To restore (reconstruct) these bone defects, human or animal bone grafts or alloplastic (synthetic) materials have been used. However, several disadvantages are associated with bone graft transplantation, such as limited bone volume, donor-s...

The basic problem with the fixation of a prosthesis, cemented or cementless, is biomechanical. The forces transmitted between it and bone will depend on the design and the surface geometry of the implant, the mechanical properties of its surface, and the operative technique. Biological problems may arise from the relative biocompatibility of the implant surface, its biochemistry, the quality of...

In order to respond to the basic requirements of food and pharmaceutical industries, to reduce or eliminate organic solvent residues in the final products, several extraction techniques were tested from the standpoint of performance, with low energy consumption. The aim of this study was to determine biological activities such as antioxidant and antiproliferative activities of flavonolignans fr...
