Understanding the cause of patchy bone distributions in archaeological sites requires that one distinguish bone decomposition in place from ‘‘empty’’ areas where bones were never present. Marked horizontal variations in bone abundance are found in the thick Mousterian layer (E) of Hayonim Cave, a large Paleolithic site in northern Israel. Infra-red analyses of minerals in the sediments identify...

The dielectric properties of bones are found to be influenced by the demineralisation bones. Therefore, microwave imaging (MWI) can used monitor in vivo human and hence aid monitoring osteoporosis. This paper presents feasibility analysis MWI device for Firstly, tissues present heel analysed. Secondly, a transmission line (TL) formalism approach is adopted examine feasible frequency band matchi...

Bone scintigraphies are widely applied for detecting bone metastases. The aim of this study was to investigate distribution features of bone metastases in pulmonary and prostate cancers. Bone scintigraphies were performed in 460 patients with pulmonary cancer and 144 patients with prostate cancer. Patients were divided into three groups according to the total number of bone metastases: few bone...

BACKGROUND It is currently unknown whether bone erosion in gout occurs through an 'inside-out' mechanism due to direct intra-osseous crystal deposition or through an 'outside-in' mechanism from the surface of bone. The aim of this study was to examine the mechanism ('outside-in' vs. 'inside-out') of monosodium urate (MSU) crystal deposition in bone erosion in gout. Specifically, we used three-d...

Using a wide range of modern mineralogical and physicochemical methods, representative collection human bones from seven burial grounds the Vychegda Permians 11th–14th centuries was studied. The microstructure bones, their chemical normative-mineral composition, content microelements, nanoporosity organo-mineral composite, composition properties bioanatite bone collagen were analyzed. Fundament...

In the present study, the process of the skull development and calcification in Persian sturgeon (Acipenser persicus) was studied. Development of cartilage started after hatching around the head and notochord (10.6 mm, total length, TL) and the first calcification process occurred in dermopalatine and dentary bone jaw coincident with mixing feeding. The appearance of dermal skeletal on the body...

The prolonged retention of fetal bone structure is an uncommon condition after a previous abortion. We describe two cases with fetal bone fragment amongst 3589 hysteroscopies (0.05%), who had no complaint other than secondary infertility. In both patients, hyperechogenic areas were found through transvaginal ultrasound and the bones were removed by hysteroscopy. Despite meticulous evaluation du...

UNLABELLED PURPOSE OF THE STUDY In a long-term perspective, it is better to remove implants after fracture healing. However, subsequent full or excessive loading of an extremity may result in refracture, and the bone with holes after screw removal may present a site with predilection for this. The aim of the study was to find ways of how to decrease risk factors for refracture in such a case. T...

AIM The accuracy of bone scintigraphy in diagnosing symptomatic accessory navicular bones has not been well studied. We conducted a retrospective study to explore the results and use of scintigraphy in symptomatic and asymptomatic accessory navicular bones. MATERIALS AND METHODS Thirteen patients with a total of 13 symptomatic and 10 asymptomatic accessory navicular bones were included in the...

Plasmacytoma refers to a distinct and localized growth of plasma cells that are neoplastic monoclonal in nature. Solitary plasmacytomas (SP) can be categorized into two groups based on their location: solitary bone plasmacytoma (SBP), which most commonly occurs the vertebrae secondarily long bones, extramedullary (EMP), encompassing SPs found outside bone. Long bones frequently affected plasmac...
