The magnet lattice of the MAX IV storage rings
A successor of the present MAX facility is currently being studied. This proposed MAX IV facility will then have two new storage rings operated at 1.5 and 3 GeV respectively. The magnet lattices of the two storage rings are almost identical and the rings are placed coaxially, one on top of the other. A third ring, the MAX III ring, now under construction, should be transferred to the new facility.
A documented amphibian decline over 40 years: Possible causes and implications for species recovery
Amphibians are declining worldwide, but lack of long-term regional data makes identifying possible causes difficult, hindering conservation efforts. We evaluated whether habitat destruction, terrestrial habitat adjacent to ponds and the physico-chemical characteristics of ponds could explain the regional and local decline of the spadefoot toad (Pelobates fuscus) in Sweden. Analyses of aerial photo
A meta-analysis of four European genome screens (GIFT Consortium) shows evidence for a novel region on chromosome 17p11.2-q22 linked to type 2 diabetes.

Pictures and spoken descriptions elicit similar eye movements during mental imagery, both in light and in complete darkness
This study provides evidence that eye movements reflect the positions of objects while participants listen to a spoken description, retell a previously heard spoken description, and describe a previously seen picture. This effect is equally strong in retelling from memory, irrespective of whether the original elicitation was spoken or visual. In addition, this effect occurs both while watching a b
Costly steroids: egg testosterone modulates nestling metabolic rate in the zebra finch
The transfer of non-genetic resources from mother to the offspring often has considerable consequences for offspring performance. In birds, maternally derived hormones are known to influence a variety of morphological, physiological and behavioural traits in the chick. So far, the range of these hormonal effects involves benefits in terms of enhanced growth and competitive ability as well as costs
Urban shading - a design option for the tropics? A study in Colombo, Sri Lanka
Recent urban microclimate studies in Colombo, Sri Lanka, indicate that the maximum daily temperature within street canyons decreases with increasing height to width (H/W) ratio, but higher H/W ratio negatively affects street-level wind flow. There is also evidence pointing to the cooling effect of sea breeze. The nocturnal heat island is small in contrast to daytime urban-rural differences. In thi
A novel diode laser system for photodynamic therapy
In this paper a novel diode laser system for photodynamic therapy is demonstrated. The system is based on linear spatial filtering and optical phase conjugate feedback from a photorefractive BaTiO3 crystal. The spatial coherence properties of the diode laser are significantly improved. The system provides an almost diffraction limited output which is efficiently coupled into a 50 mum core diameter

The growth of external AM fungal mycelium in sand dunes and in experimental systems
We estimated the biomass and growth of arbuscular mycorrhizal (AM) mycelium in sand dunes using signature fatty acids. Mesh bags and tubes, containing initially mycelium-free sand, were buried in the field near the roots of the dune grass Ammophila arenaria L. AM fungal mycelia were detected at a distance of about 8.5 cm from the roots after 68 days of growth by use of neutral lipid fatty acid (NL
Enhancement of hepatitis A propagation in tissue culture with 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole
The adenosine analog 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB) was found to increase the production of hepatitis A (HAV) antigen in two monkey kidney cell lines (Frhk-4 and Vero cells). DRB, a known inhibitor of the synthesis of messenger RNA, caused moderate changes in cell morphology. However, Frhk-4 cells could be maintained for several weeks at 80 microM of DRB, the concentration
Reduction of intraocular pressure and glaucoma progression: results from the Early Manifest Glaucoma Trial.
Molecular organization in striated domains induced by transmembrane alpha-helical peptides in dipalmitoyl phosphatidylcholine bilayers
Transmembrane (TM) alpha-helical peptides with neutral flanking residues such as tryptophan form highly ordered striated domains when incorporated in gel-state 1,2-dipalmitoyl-sn-glycero-3-phosphocholine (DPPC) bilayers and inspected by atomic force microscopy (AFM) (1). In this study, we analyze the molecular organization of these striated domains using AFM, photo-cross-linking, fluorescence spec
Endotoxin receptor CD14 in PiZ alpha-1-antitrypsin deficiency individuals
Background: CD14, a receptor for lipopolysaccharides (LPS), is found in both a membrane-bound form (mCD14) and a soluble form (sCD14). It is suggested that sCD14 is mainly released from blood monocytes by serine protease-mediated shedding. Because alpha(1)-antitrypsin (AAT), an inhibitor of serine proteases, has been shown to regulate CD14 expression in human monocytes in vitro, we sought to inves
Temporal trends of esophageal cancer during 1995-2004 in Nanao Island, an extremely high-risk area in China
The purpose of our study was to investigate the temporal malignant tumor incidence rates among the 70,000 residents at the relatively isolated Nanao Island in South China Sea. The data on all malignant tumor cases from Nanao Cancer Registry during 1995-2004 were coded, computerized, and analyzed using the software SPSS10.0. The tumor incident cases, crude incident rate, age-standardized incidence
Integrated system for interstitial photodynamic therapy
A novel photodynamic therapy system based on interstitial illumination using multiple fibres is under development. The aim with this system is to enable treatment of large tumour volumes and also to utilise real-time measurements to allow on-line dosimetry. Important dosimetric parameters to measure are light fluence rate, sensitizer fluorescence intensity and local blood oxygenation. A constructi
Cancer Risk in Patients With Rheumatoid Arthritis Treated With Anti-Tumor Necrosis Factor alpha Therapies Does the Risk Change With the Time Since Start of Treatment?
Objective. To determine the short-term and medium-term risks of cancer in patients receiving antitumor necrosis factor alpha (anti-TNF alpha) therapies that have proven effective in the treatment of chronic inflammatory conditions. Methods. By linking together data from the Swedish Biologics Register, Swedish registers of RA, and the Swedish Cancer Register, we identified and analyzed for cancer o
Lateglacial and early Holocene vegetation development in the Gutaiului Mountains, northwestern Romania
Pollen analyses and AMS C-14 measurements were performed on lacustrine sediments and peat sequences from two former crater lakes (Preluca Tiganului, Steregoiu) situated in the Gutaiului Mountains in northwestern Romania, in order to reconstruct the vegetation development during the Lateglacial and Early Holocene. Before c. 14,700 cal. years BP (GS-2) open vegetation with shrubs (Salix, Juniperus),
