Bone age assessment is a task performed daily in hospitals worldwide. This involves a clinician estimating the age of a patient from a radiograph of the non-dominant hand. Our approach to automated bone age assessment is to modularise the algorithm into the following three stages: segment and verify hand outline; segment and verify bones; use the bone outlines to construct models of age. In thi...

background: for tissue engineering of bone, anatomical and operational reconstructions of damaged tissue seem to be vital. this is done via reconstruction of bone and appropriate biological joint with bone tissues of damaged areas. in this study the condition of biodegradable bed nano fiber phbv and ussc cells were used to accelerate bone repair of damaged area. methods: hollow nanofabrication ...

INTRODUCTION Bone infections after trauma, i.e. posttraumatic osteomyelitis, pose one of the biggest problems of orthopedic surgery. Even after sufficient clinical therapy including vast debridement of infected bone and antibiotic treatment, regeneration of postinfectious bone seems to be restricted. One explanation includes the large sized defects resulting from sufficient debridement. Further...

  Osteoid osteoma is a benign bone tumor that rarely involves joints. Although there are several reports of arthroscopic osteoid osteoma excisions, to our knowledge, there are no reports of this type of treatment for osteoid osteoma in carpal bones. We report two cases of arthroscopic (a person who had a pain in the left wrist and the other one with carpal tunnel syndrome) with excision of oste...

A large group of human bones were excavated during the 1930’s from the Moundville archaeological site in Alabama. If a chronology could be assigned to them, the bones might provide a guide to the changes which took place as Moundville flourished, since pottery and other objects were often buried with the individuals. A recent pottery classification based on style suggests three major time perio...

Hematopoietic stem cells (HSCs) in the endosteum of mesoderm-derived appendicular bones have been extensively studied. Neural crest-derived bones differ from appendicular bones in developmental origin, mode of bone formation and pathological bone resorption. Whether neural crest-derived bones harbor HSCs is elusive. Here, we discovered HSC-like cells in postnatal murine mandible, and benchmarke...

Two groups of feedlot cattle on two different mineral supplement trials were used to assess the relationship between temperament and cannon bone measurements. The cannon bones of approximately fourteen month old crossbred Bos taurus European, Continental, and British steers (n = 135), primarily Angus, Charolais, and Hereford breeds, and 54 Charolais x Hereford heifers were measured postmortem. ...

The influence of sex on bone mineral density (BMD) and the bone mineral content (BMC) have been analysed in selected bones of the thoracic and pelvic limbs of African ostriches. The examination was conducted with the use of a densitometer, using the technology of affinited beam of X-ray and the programme for animal research. It was shown that the analysed bones of ostrich skeleton differed sign...

Oxidative stress affects bone turnover. Preventative effects of antioxidants such as vitamin E on reduced bone mineral density and fractures associated with aging, osteoporosis, and smoking have been examined in animals and humans. The effects of vitamin E (α-tocopherol; αT) on bone health have yielded conflicting and inconclusive results from animal studies. In this study, to determine the bon...

The influence of pregnancy on bone tissue metabolism is not completely understood. Caffeine also has a potentially negative influence on bones. The aim of this study was the evaluation of changes in the bones of pregnant rats under the influence of caffeine. The experiment was carried out on Wistar rats. The evaluation of rats' bone tissue quality was performed based on bone density measurement...
