Fracture of human femoral bone
Journal of Biomechanics, 1984The work-of-fracture of human femoral bone was determined using the technique of Tattersal and Tappin (1966). The work required to fracture a specimen in three point bending by slow crack propagation through a triangular cross-section is obtained from the load-deflection curve. The area of the resulting fracture surface is measured by macrophotographic

Micromegakaryocytes in Human Bone Marrow
Acta Haematologica, 2009Micromegakaryocytes (MMK) were defined morphologically by the cell area, nucleus form and cytoplasmic structure. Bone marrow smears of 7,156 patients were retrospectively analyzed. MMK were found most frequently and abundantly in acute non-lymphatic leukaemia, chronic myeloid leukaemia and pre-leukaemia.

Bone, 2006
Bone has exceptional regenerative properties. Oral bone appears to be particularly resistant to infection despite exposure to oral flora, even in circumstances such as oral surgery where the thin mucosal layer covering the bone is disrupted. The goal of this study was to determine whether the innate immune system of antimicrobial peptides exists inside

Palatine Bone in Human Cyclopia
Cells Tissues Organs, 1989In human cyclopia, a maxillopalatine mass separates the median orbit from the oral cavity.The palatine component of this bony mass has been studied in serial sections through the median third of the head in three perinatal human specimens presenting with a median orbit and proboscis.

Bone Resorption in Human Cholesteatomas
Annals of Otology, Rhinology & Laryngology, 1982In vivo studies of different aspects of bone resorption in human cholesteatomas are described in the immunodeficient “nude” mice. Cholesteatoma membranes were transplanted into the middle ear cavities of the mice. After 21–28 days, growth of cholesteatoma tissue could be demonstrated in 8 of 13 animals.

Embryogenesis of the human occipital bone
American Journal of Roentgenology, 1976From an original study of fetal specimens, the embryogenesis of the human occipital bone is described. The occipital bone in man is derived from cartilage, except for the interparietal segment which has a membranous origin. Normally there is no midline cerebellar fissure or synchondrosis.

Structure of Human Fluorotic Bone
The Journal of Bone & Joint Surgery, 1973Fluorotic bone specimens obtained from the skeletons of two subjects with advanced fluorosis and from bone biopsies of other patients have been shown to contain deposits of bone on the surface which form an irregular sleeve of new bone and many exostoses.

Studies of Radium in Human Bone
Radiology, 1951EXtensive Experience with human beings and numerous animal experiments have shown beyond doubt that a portion of any quantity of radium which enters the body will be deposited in the bones, and that osteogenic sarcomas are often associated with small quantities of radium which have been fixed in the bone for considerable periods of time (1).

Bone transplantation is often used for the reconstruction of defects. The best results are achieved with autogenous grafts because they induce no immunological reaction, but allogeneic grafts from bone banks are frequently used to provide an adequate volume of bone (Cookson et al 1988).

The impact of microgravity on bone in humans
Bone, 2016Experiencing real weightlessness in space is a dream for many of us who are interested in space research. Although space traveling fascinates us, it can cause both short-term and long-term health problems. Microgravity is the most important influence on the human organism in space.
