Alveolar albumin leakage during large tidal volume ventilation and surfactant dysfunction
Detergent given as an aerosol and large tidal volume ventilation (LTVV) have been observed, by us, to promote lung injury by an additive effect on alveolocapillary barrier function. The surfactant system may be further damaged if protein leakage occurs into the alveoli. The aim was to study the effect of detergent and LTVV on the alveolar leakage of albumin and also the effect of detergent on surf
Overexpression of Gibbon Ape Leukemia Virus (GALV) Receptor (GLVR1) on Human CD34(+) Cells Increases Gene Transfer Mediated by GALV Pseudotyped Vectors.
Retroviral transduction of CD34(+) cells on Retronectin using gibbon ape leukemia virus (GALV) pseudotyped vectors is inhibited by high concentrations of vector containing medium (VCM). Furthermore, this inhibitory activity is stable for at least 48 hours at 37 degrees C and partially blocks a second hit with a GALV pseudotyped vector. We hypothesized that this inhibition was due to interference a
Diversity of Mhc class I and IIB genes in house sparrows (Passer domesticus)
In order to understand the expression and evolution of host resistance to pathogens, we need to examine the links between genetic variability at the major histocompatibility complex (Mhc), phenotypic expression of the immune response and parasite resistance in natural populations. To do so, we characterized the Mhc class I and IIB genes of house sparrows with the goal of designing a PCR-based geno
Characterization of multimodal hydrophobic interaction chromatography media useful for isolation of green fluorescent proteins with small structural differences.
Hydrophobic interaction chromatography (HIC) has been developed as a powerful technique for separating and purifying proteins. In this study, we have characterized the ability of new multimodal pH-HIC media to resolve proteins with only small differences in their primary structures. This was done by determining the retention times of different green fluorescent protein (GFP) mutants prepared from
Improved radiographic survival of the Charnley prosthesis in rheumatoid arthritis and osteoarthritis. Results of new versus old operative techniques in 402 hips
Two hundred one consecutive, primary, noninfected Charnley (Thackray, Leeds) hip arthroplasties, implanted from 1968 to 1985 due to adult-onset rheumatoid arthritis, were matched in pairs with respect to year of operation, age, and sex with 201 Charnley prostheses implanted due to osteoarthritis. The 10-year survival estimate for nonrevisions was 95% in the rheumatoid group and 89% in the osteoart
The mitotic arrest in response to hypoxia and of polar bodies during early embryogenesis requires Drosophila Mps1
Mps1 kinase plays an evolutionary conserved role in the mitotic spindle checkpoint [1-8]. This system precludes anaphase onset until all chromosomes have successfully attached to spindle microtubules via their kinetochores [9]. Mps1 overexpression in budding yeast is sufficient to trigger a mitotic arrest, which is dependent on the other mitotic. checkpoint components, Bub1, Bub3, Mad1, Mad2, and
MQX-503, a novel topical nitroglycerin formulation, improves severity of symptoms associated with Raynaud's phenomenon
Subsolidus phase equilibria and crystal chemistry in the system BaO-TiO2-Ta2O5.
Subsolidus phase relations have been determined for the BaO:TiO2:Ta2O5 system by X-ray diffraction analysis of ~100 specimens prepared in air at temperatures near but below the solidus (1275 °C to 1500 °C). For the BaO:Ta2O5 subsystem, the formation of all three polymorphs of BaTa2O6 (orthorhombic, tetragonal, and hexagonal) was confirmed. The present study found no stable phases forming between B
Complement factors are expressed in pancreatic islets and affect glucose induced insulin secretion
Oral bioavailability of the antioxidant astaxanthin in humans is enhanced by incorporation of lipid based formulations.
Iron status influences trace element levels in human
Food is the main source of trace elements for the general Population. The gastrointestinal absorption of certain trace elements, e.g., cadmium, is strongly influenced by iron (Fe) status. This factor may also be relevant for the bioavailability of other trace elements. Therefore, we investigated relationships between Fe status indicators and trace element concentrations in blood and serum of 234 b

Quantification of myocardial perfusion defects using three different software packages.
Software packages are widely used for quantification of myocardial perfusion defects. The quantification is used to assist the physician in his/her interpretation of the study. The purpose of this study was to compare the quantification of reversible perfusion defects by three different commercially available software packages. We included 50 consecutive patients who underwent myocardial perfusion

On-line Arabic handwriting recognition with templates
After a long period of focus on western and East Asian scripts there is now a general trend in the on-line handwriting recognition community to explore recognition of other scripts such as Arabic and various Indic scripts. One difficulty with the Arabic script is the number and position of diacritic marks associated to Arabic characters. This paper explores the application of a template matching s
Solvent-free enzymatic synthesis of fatty alkanolamides
An environmentally benign and volume efficient process for enzymatic production of alkanolamides is described. Immobilized Candida antarctica lipase B, Novozym (R) 435, was used to catalyze the condensation of lauric acid with monothanolamine. The raction temperature of 90 degrees C was required to keep the reactants in a liquid state. Atepwise addition of the amine minimized problems caused by th
Patient willingness-to-pay for liraglutide and exenatide in Sweden based on head-to-head clinical trial results
A wavelet semidiscretisation of elastic multibody systems
In this paper we consider a coupled system of elastic and rigid bodies. It can be mathematically formulated as a coupled system of ordinary and partial differential equations, often written in its weak form. The discretisation is performed by a Galerkin-type ansatz in connection with a finite element approach or known eigenfunctions. Here, we demonstrate instead the use of a recently published Gal
Numerically produced forming limit diagrams for metal sheets with voids considering micromechanical effects
A numerical study of how changes in the micromechanical modeling affect the formability of voided metal sheets is conducted. A homogenization technique, where periodic representative volume elements are used, permits investigations of the global formability where the local material mechanisms and the microstructure are accounted for. A nonlocal material model, containing a constitutive material le
