despite the long history of the worldwide use of bacillus calmette-guerin (bcg) vaccine, a wide spectrum of adverse reactions has been observed in a small proportion of immunized infants; the most severe complication, disseminated bcgitis, is often fatal but exceedingly rare and is considered to result from host immunodeficiency. at present, ct scan, ultrasound, x-ray and bone marrow aspiration...

Cystic fibrosis (CF) is a common progressive genetic disorder among children which involves lungs, kidneys, intestine and liver. Apart from the significance of genetic factors, various environmental factors particularly bone mineral density are directly associated with CF. Remarkably, bone disease is appeared as a routine and commo...

Delayed bone healing and non-union occur in approximately 10% of long bone fractures. Despite intense investigations and progress in understanding the processes governing bone healing, the specific pathophysiological characteristics of the local microenvironment leading to non-union remain obscure. The clinical findings and radiographic features remain the two important landmarks of diagnosing ...

Replace this text with your own abstract. A natural similarity in body dimensions of terrestrial animals noticed by ancient philosophers remains the main key to the problem of mammalian skeletal evolution with body mass explored in theoretical and experimental biology and tested by comparative zoologists. We discuss the long-standing problem of mammalian bone allometry commonly studied in terms...

Previous studies have shown a strong correspondence between long bone bilateral asymmetry and reported handedness. Here, we compare the pattern of asymmetry in mechanical properties of the humerus and second metacarpal of Pan troglodytes, recent British industrial and medieval populations, and a broad range of human hunter-gatherers, to test whether technological variation corresponds with late...

Distinguishing human from non-human bone fragments is usually accomplished by observation of gross morphology. When macroscopic analysis is insufficient, histological approaches can be applied. Microscopic features, like plexiform bone or osteon banding, are characteristic of non-humans. In the absence of such features, distinguishing Haversian bone as either human or non-human proves problemat...

myositis ossificans (mo) is a pathologic bone formation in soft tissue with unknown pathogenesis. in this article, we reported a case of long standing mo of right medial pterygoid muscle with severe limitation of mouth opening.

The broad biogeographic distribution of Hesperornis fossils in Late Cretaceous Western Interior Seaway deposits has prompted questions about whether they endured polar winters or migrated between mid- and high latitudes. Here, we compare microstructures of hesperornithiform long bones from Kansas and the Arctic to investigate whether migration or Late Cretaceous polar climate affected bone grow...
