TL;DR: In this article, the same bacterial species were cultured by routine microbiological techniques from only five corresponding tissue samples and inflammatory cells were present in 87% of the samples taken from patients whose implants were culture-negative.
Abstract: Our aim was to determine if the detection rate of infection of total hip replacements could be improved by examining the removed prostheses. Immediate transfer of prostheses to an anaerobic atmosphere, followed by mild ultrasonication to dislodge adherent bacteria, resulted in the culture of quantifiable numbers of bacteria, from 26 of the 120 implants examined. The same bacterial species were cultured by routine microbiological techniques from only five corresponding tissue samples. Tissue removed from 18 of the culture-positive implants was suitable for quantitative tissue pathology and inflammatory cells were present in all samples. Furthermore, inflammatory cells were present in 87% of tissue samples taken from patients whose implants were culture-negative. This suggests that these implants may have been infected by bacteria which were not isolated by the techniques of culture used. The increased detection of bacteria from prostheses by culture has improved postoperative antibiotic therapy and should reduce the need for further revision.

01 Jun 2006TL;DR: In this paper, the main theoretical approaches and computational techniques, from the simplest approximations to the most sophisticated methods, are described, from a theoretical perspective, for electronic structure problems.
Abstract: Electronic structure problems are studied in condensed matter physics and theoretical chemistry to provide important insights into the properties of matter. This 2006 graduate textbook describes the main theoretical approaches and computational techniques, from the simplest approximations to the most sophisticated methods. It starts with a detailed description of the various theoretical approaches to calculating the electronic structure of solids and molecules, including density-functional theory and chemical methods based on Hartree-Fock theory. The basic approximations are thoroughly discussed, and an in-depth overview of recent advances and alternative approaches in DFT is given. The second part discusses the different practical methods used to solve the electronic structure problem computationally, for both DFT and Hartree-Fock approaches. Adopting a unique and open approach, this textbook is aimed at graduate students in physics and chemistry, and is intended to improve communication between these communities. It also serves as a reference for researchers entering the field.

TL;DR: In this article, the first fluorinase enzyme was identified in the bacterium Streptomyces cattleya and it was shown that it can catalyse the conversion of S-adenosylmethionine (SAM) to 5'-fluoro-5'-deoxyfluoroadenosine (5'-FDA).
Abstract: Although fluorine in the form of fluoride minerals is the most abundant halogen in the Earth's crust, only 12 naturally occurring organofluorine compounds have so far been found, and how these are biosynthesized remains a mystery. Here we describe an enzymatic reaction that occurs in the bacterium Streptomyces cattleya and which catalyses the conversion of fluoride ion and S-adenosylmethionine (SAM) to 5'-fluoro-5'-deoxyfluoroadenosine (5'-FDA). To our knowledge, this is the first fluorinase enzyme to be identified, a discovery that opens up a new biotechnological opportunity for the preparation of organofluorine compounds.

TL;DR: In this article, the authors review the development of the field of entrepreneurship as a context for the emergence of learning as an area of scholarly attention, summarize a number of key themes emerging from the organizational learning literature, and outline the article selection process and summarize the key elements of each of the included articles.
Abstract: The context for the research presented in this article arises from increasing interest, by academics and practitioners, in the importance of learning and knowledge in the knowledge-based economy. In particular, we consider the scope for applying concepts of learning within the field of entrepreneurship. While it has gained currency within the field of management, the application of these concepts to entrepreneurship has been limited. In this Introduction to the Special Issue, we review the development of the field of entrepreneurship as a context for the emergence of learning as an area of scholarly attention, summarize a number of key themes emerging from the organizational learning literature, and outline the article selection process and summarize the key elements of each of the included articles. The article concludes with some reflections on future research at the interface between learning and the entrepreneurial context.

TL;DR: Myopia is becoming more common in Europe; although education levels have increased and are associated with myopia, higher education seems to be an additive rather than explanatory factor.
