Overall contamination (on- plus off-streak) of the Isolator (Du Pont Co.) blood culture tube (23%) was greater than that of a conventional broth blood culture bottle (0.6%) or that of a biphasic blood culture bottle (1.3%). To determine the source of this contamination, Isolator cultures of blood from 59 healthy volunteers and of sterile broth from 60 vials were made. A total of 37% of the bloo...
With recent development of the nanotechnology, nanomaterials have been successfully employed in various industrial applications such as medicine and cosmetics. Nanomaterials show the useful properties such as electronic reactivity and the tissue permeability that were not provided by micromaterials. Thus, nanomaterials are expected as innovative materials for the development of medicine and cos...
Recently, it has been proven that cartilage healing is difficult. The most commonly used treatments are autogenously cartilage grafting and allogeneic bone grafting, but grafts cannot fully meet treatment goals because of source, price, safety, and other concerns. Thus, a combination of biological materials and tissue engineering technology has become a recent trend in studies. Among the studie...
For any software system upon which lives depend, the most important question one can ask about it is, ‘How do we know the system is safe?’ Despite the critical importance of this question, no widely accepted, generally applicable answer exists. Instead, debate continues to rage over the question, with theorists and practitioners quarrelling with each other and amongst themselves. This paper sug...
