Mechanical loading of bone results in various osteogenic stimuli, including new bone formation as well as repair. Osteocytes are thought to be critical for sending signals to other bone cells However, few markers for osteocytes are recognized and the gene expression patterns and pathways of osteocytes responding to mechanical loading are not well defined. To understand the characteristic genes ...

Terminal deoxynucleotidyl transferase is an enzyme which has the unique property of polymerizing polydeoxynucleotides onto a primer in the absence of a template (1, 2). This enzyme is found both in the thymus and the bone marrow of birds, rodents, and humans (3-7). Whether the marrow cells that contain terminal transferase are related to thymocytes, or are on a separate pathway of differentiati...

Whale bones and wood on the deep-sea floor provide resource pulses that support characteristic faunal assemblages in an otherwise food-poor environment. To isolate role of bathymetric geographical drivers organic-fall diversity community structure, study organic-rich substrates similar sizes, qualities, seafloor durations is necessary. We used a comparative experimental approach to examine role...

A comprehensive study of feed staff animal origin was carried out to identify the most efficient ways use as components compound feeds. In samples feeds (fish meal, fish extrudate, meat and bone meal), parameters nutritional value safety were determined. It found that stable content crude protein essential critical amino acids characteristic which is advisable be used for purpose balancing youn...

conclusion for the identification of nasal bone fractures, ct was significantly superior to conventional radiography. although a staff radiologist showed better values in the identification of nasal bone fracture and differentiation between depressed and non-depressed fractures than a trainee, there was no statistically significant difference in the interpretation of conventional radiography an...

statement of problem: it is not known whether endochondral and intramembranous bones have distinct biological characteristics. octacalcium phosphate (ocp), a hydroxyapatite precursor, has been reported to stimulate bone formation after being implanted in parietal bone defects of rats. purpose: the present study was designed to investigate the response of endochondral and intramembranous bones t...

The diagnosis of a bone tumor in a child can be a source of great anxiety for the patient, the parents, and the treating physician. Fortunately, most bone tumors in children are benign. Although there are a variety of benign bone tumors that affect skeletally immature patients, most have such characteristic clinical and radiographic presentations that the diagnosis can be made with reasonable a...

Many of the sclerosing bone dystrophies fall within the classification employed by Fairbank (1951). However, patients occasionally present features suggesting a possible relationship between osteopoikilosis (spotted bones), osteopathia striata (striated bones, Voorhoeve’s disease), melorheostosis (running wax bones) and osteopetrosis (dense or marble bones). Areas of dense bone arranged in diff...

Introduction: Since between 25-30% bone fractures, and 60% hip fractures in the general population are common in the subgroup which correspond to very old women. This happens due to the high predominance of primary osteoporosis and the incidence of falls which are characteristic of such group; thus, we have decided to investigate, through a systematic revision of the bibliography, the value of ...
