Bose-Einstein correlations of charged kaons are used to probe Au+Au collisions at s(NN)=200 GeV and are compared to charged pion probes, which have a larger hadronic scattering cross section. Three-dimensional Gaussian source radii are extracted, along with a one-dimensional kaon emission source function. The centrality dependences of the three Gaussian radii are well described by a single linear

OBJECTIVE: To investigate changes in regional blood flows (RBF) and vascular porosity during the early phase of the autologous collagen II induced arthritis model (CIA) in rats and the possible influence of indomethacin and nitric oxide (NO) synthase on these variables. METHODS: RBF was measured with the microsphere method and vascular porosity by determination of extravasation of radiolabeled alb

Molecular characterization of ten marine cyanobacterial isolates belonging to the order Oscillatoriales was carried out using the phycocyanin locus (cpcBA-IGS) and the 16S-23S internally transcribed spacer region. DNA sequences from the phycocyanin operon discriminated ten genotypes, which corresponded to seven morphotypes identified by traditional microscopic analysis. The cpcB coding region reve

We studied long-term trends and the yearly variation in mean spring passage time in 36 passerine bird species trapped at Ottenby Bird Observatory in south-eastern Sweden. Between the years 1952-2002, data were available for 22-45 years depending on species. Most long-distance migrant species passed progressively earlier over the study period (range: 2.5 days earlier to 0.7 days later per 10 years,

OBJECTIVES: This study investigated the association between occupational and hobby exposure and the risk of myelodysplastic syndromes (MDS) while focusing on differential patterns of clonal chromosome aberrations and morphologic subgroups. METHODS: A case-referent study was conducted with 330 MDS patients investigated cytogenetically in 1976-1993 (cases) and matched referents. Telephone interviews

BACKGROUND: The Palliative Medicine Unit at University Hospital of Trondheim, Norway, started an intervention programme that aims to enable patients to spend more time at home and die there if they prefer. Close cooperation was needed with the community health-care professionals, who acted as the principal formal caregivers, and a multidisciplinary consultant team coordinated the care. We did a cl

Islet function is regulated by a number of different signals. A main signal is generated by glucose, which stimulates insulin secretion and inhibits glucagon secretion. The glucose effects are modulated by many factors, including hormones, neurotransmitters and nutrients. Several of these factors signal through guanine nucleotide-binding protein (G protein)-coupled receptors (GPCR). Examples of is

A synthesis inversion based on the atmospheric zoom model TM5 is used to derive top-down estimates of CH4 emissions from individual European countries for the year 2001. We employ a model zoom over Europe with 1 degrees x 1 degrees resolution that is two-way nested into the global model domain (with resolution of 6 degrees x 4 degrees). This approach ensures consistent boundary conditions for the

The colorimetric variations induced upon changes in interfacial refractive index of nanoscale noble metal structures exhibiting localized surface plasmon resonance (LSPR) provides a convenient means of label-free, affinity-based detection of biomolecular recognition reactions. However, despite being similar in nature to conventional SPR, LSPR has so far suffered from significantly lower data quali

Differences in hormonal and constitutional parameters between women with at least one first and/or second degree relative with breast cancer (RBC) and women without such affected relatives were studied in a group of healthy, nulligravid women aged 19-25 years. Present oral contraceptive (OC) users were analysed separately. In women not presently exposed to OCs we found significant correlations bet

Growth hormone (GH) has been used as anabolic therapy to treat catabolic patients. In a recent study, however, administration of high doses of GH to critically ill adults was associated with an increase in morbidity and mortality. Preponderance of septic shock and uncontrolled infections as causes of death in these patients suggests an immuno-modulatory effect of GH. Our hypothesis was that GH tre

The influence of molecular characteristics on the mutual interaction between peptides and nonionic surfactants has been investigated by studying the effects of surfactants on amphiphilic, random copolymers of alpha-L-amino acids containing lysine residues as the hydrophilic parts. The hydrophobic residues were either phenylalanine or tyrosine. The peptide-surfactant interactions were studied by me

The structure of calerythrin, a prokaryotic 20 kDa calcium-binding protein has been determined by solution NMR spectroscopy. Distance, dihedral angle, J coupling, secondary chemical shift, residual dipolar coupling and radius of gyration restraints reveal four EF-hand motifs arranged in a compact globular structure. A tight turn in the middle of the amino acid sequence brings the two halves, each

Aim: Obesity is associated with increased levels of inflammatory mediators. The objective of this study was to evaluate changes in the leucocyte derived inflammatory mediators tumour necrosis factor alpha (TNF-alpha), interleukin 6 (IL-6) and the isoprostane 8-epi-prostaglandin (PG) F2alpha during BMI lowering with orlistat (Xenical®, Roche) or placebo. Methods: TNF-alpha, IL-6, and 8-epi PGF2alp

Pictorial visualization is expected to facilitate communication between industrial professionals when planning working environments and production systems. This hypothesis was investigated by studying how 24 participants including managers, supervisors, machine operators, and occupational health and safety officials, judged three types of computer animated visualization varying in dimensional view

Nine species of hyoliths are described based on material collected in Skane, southern Sweden, during the first half of the last century. The material derives from the middle Cambrian (Cambrian provisional Series 3) Exsulans Limestone Bed at Almbacken east of Lund and the Upper Ordovician (Katian-Hirnantian) Lindegard Formation at Tommarp west of Simrishamn. The Almbacken assemblage consists of thr

Study objective: This didactical essay is directed to readers disposed to approach multilevel regression analysis (MLRA) in a more conceptual than mathematical way. However, it specifically develops an epidemiological vision on multilevel analysis with particular emphasis on measures of health variation (for example, intraclass correlation). Such measures have been underused in the literature as c
