This book presents the most important issues related to infections with Mycoplasma bovis, an etiological agent of many disorders in cattle, such as bronchopneumonia, mastitis, arthritis, otitis, keratoconjunctivitis, meningitis, and endocarditis. It consists of one review and eight research articles that discuss lung local immunity in experimental M. bovis pneumonia, antimicrobial susceptibility of M. bovis isolates, aspects related to M. bovis antibody testing, new data on the efficacy of seminal extender in M. bovis, as well as the importance of imported bull examination for this pathogen.

MILS-15 provides an up-to-date review of the metalloenzymes involved in the activation, production, and conversion of molecular oxygen as well as the functionalization of the chemically inert gases methane and ammonia. Found either in aerobes (humans, animals, plants, microorganisms) or in anaerobes (so-called “impossible bacteria”) these enzymes employ preferentially iron and copper at their active sites, in order to conserve energy by redox-driven proton pumps, to convert methane to methanol, or ammonia to hydroxylamine or other compounds. When it comes to the light-driven production of molecular oxygen, the tetranuclear manganese cluster of photosystem II must be regarded as the key player. However, dioxygen can also be produced in the dark, by heme iron-dependent dismutation of oxyanions. Metalloenzymes Mastering Dioxygen and Other Chewy Gases is a vibrant research area based mainly on structural and microbial biology, inorganic biological chemistry, and environmental biochemistry. All this is covered in an authoritative manner in 7 stimulating chapters, written by 21 internationally recognized experts, and supported by nearly 1100 references, informative tables, and over 140 illustrations (many in color). MILS-15 provides excellent information for teaching; it is also closely related to MILS-14, The Metal-Driven Biogeochemistry of Gaseous Compounds in the Environment.  Peter M. H. Kroneck is a bioinorganic chemist who is exploring the role of transition metals in biology, with a focus on functional and structural aspects of microbial iron, copper, and molybdenum enzymes and their impact on the biogeochemical cycles of nitrogen and sulfur. Martha E. Sosa Torres is an inorganic chemist, with special interests in magnetic properties of newly synthesized transition metal complexes and their reactivity towards molecular oxygen, applying kinetic, electrochemical, and spectroscopic techniques.

This thesis addresses fundamental scientific questions such as: How are complex natural products synthesized in vivo? Can we replicate these conditions in a laboratory environment? What is the biological function of such secondary metabolites? What are the biological origins of chirality? These issues are explored in an accessible manner using a multidisciplinary approach spanning chemistry, biology and physics to investigate an interesting family of complex natural products isolated from marine molluscs – the tridachiahydropyrones.   The work has achieved: Elegant biomimetic syntheses of a number of the tridachiahydropyrone compounds in vitro using organic synthesis techniques The characterization of the interactions between these compounds and a range of model membrane systems using a series of fluorescence spectroscopic studies The investigation of the antioxidant and photoprotective properties of the compounds by means of biophysical assay techniques The synthesis of tridachiahydropyrone utilizing the model membrane systems as biomimetic reaction media.

In 1772 in Uppsala the Swedish chemist Karl Wilhelm Scheele discovered the element Oxygen. Two hundred and one years later, in 1973, the International Society on Oxygen Transport to Tissue (ISOTT) was founded. Since then there has been an annual ISOTT meeting. After 24 years of international ISOTT meetings it was decided, at the 2005 summit in Bary, Italy, that the 2007 meeting was to be held in Uppsala, Sweden. Thus, after the Louisville meeting we, in the Uppsala group, withdrew to the Edgewater Resort at Taylorsville Lake outside Louisville and prepared the Uppsala ISOTT meeting by tasting Kentucky Bourbons, smoking cigars while bathing in a jacuzzi in the hot dark Kentucky night full of fire flies and a sky full of stars. The ISOTT program should include different aspects of oxygen - however, it is accepted that each meeting has its own local “touch”. We decided to focus the Uppsala ISOTT meeting on the theme of "Imaging and measuring oxygen changes". With this in mind we invited scientists within and outside the ISOTT society. We then also received lots of good abstracts from ISOTT members that were included in the program. Lars-Olof Sundelöf introduction speech “AIR AND FIRE” concerned how oxygen was discovered in Uppsala in 1772 by Karl Wilhelm Scheele. After the introduction speech a get together event took place in the magnificent and spacious foyer of Uppsala University main building. The vice chancellor Ulf Pettersson welcomed all delegates to Sweden and Uppsala.
