The purpose of this study was to compare the structural properties of a new vs. established design of composite replicate femurs and tibias. The new design has a cortical bone analog consisting of short-glass-fiber-reinforced (SGFR) epoxy, rather than the fiberglass-fabric-reinforced (FFR) epoxy in the currently available design. The hypothesis was that this new cortical bone analog would impro...

To determine whether ancient DNA (aDNA) can be used to study the palaeopathology of venereal syphilis, we carried out a comprehensive analysis of the preservation of human and pathogen DNA in a set of 46 bones of various ages, most of which displayed osteological indications of the disease. Bones came from seven English cemetery sites that were in use during the 9the19th centuries. Twelve of th...

hyperparathyroidism is an endocrine abnormality that frequently causes diffuse osteopenia in the bones. osteosclerosis is a rare phenomenon in adults with primary hyperparathyroidism since the usual skeletal manifestation is generalized osteopenia. we describe a patient with generalized osteosclerosis in the jaws and skull in association with primary hyperparathyroidism, while the other skeleta...

Syphilis of bones is one of those conditions which is generally regarded as being less common than it used to be; and certainly one can hardly doubt that, within the span of living memory, there has been a considerable decline in its incidence. Looking through the literature of the last 20 years or more, one is struck by the fact that there have been relatively few references to this condition,...

As a general practitioner to whom patients presumably look for a source of disinterested information about their health, I have difficulty knowing what to make of the latest recommendations in the osteoporosis clinical practice guidelines and accompanying commentary. Contained therein is an expanded list of indications for testing and drug treatment for osteoporosis as recommended by a group of...

Tuberculosis appears to be increasing throughout the world after years of continuous decline, despite the introduction of effective chemotherapy. This resurgence is related to the increasing number of patients immunocompromised by chemotherapeutic agents used to treat other diseases or AIDS; the appearance of multiple drug-resistant strains of tuberculosis, and aging population. Several species...

If all we want from a syntactic parser is a dependency tree, what do we gain by first computing a different representation such as a phrase structure tree? The principle of parsimony suggests that a simpler model should be preferred over a more complex model, all other things being equal, and the simplest model is arguably one that maps a sentence directly to a dependency tree – a bare-bones de...
