A distributed two-pore model: theoretical implications and practical application to the glomerular sieving of Ficoll

In the present study, an extended two-pore theory is presented where the porous pathways are continuously distributed according to small-and large-pore mean radii and SDs. Experimental glomerular sieving data for Ficoll were analyzed using the model. In addition, several theoretical findings are presented along with analytic solutions to many of the equations used in distributed pore modeling. The

C-reactive protein and leucocyte counts drop faster using the HeartShield® device in patients with DSWI.

Right ventricular heart rupture is a devastating complication associated with negative pressure wound therapy (NPWT) in cardiac surgery. The use of a rigid barrier disc (HeartShield™) has been suggested to offer protection against this lethal complication by preventing the heart from being drawn up by the negative pressure and damaged by the sharp sternum bone edges. Seven patients treated with co

Nova1 is a master regulator of alternative splicing in pancreatic beta cells.

Alternative splicing (AS) is a fundamental mechanism for the regulation of gene expression. It affects more than 90% of human genes but its role in the regulation of pancreatic beta cells, the producers of insulin, remains unknown. Our recently published data indicated that the 'neuron-specific' Nova1 splicing factor is expressed in pancreatic beta cells. We have presently coupled specific knockdo

Model validation image data for breakup of a liquid jet in crossflow: part I

We have applied three different imaging diagnostics: particle imaging velocimetry, high-speed shadowgraphy, and ballistic imaging, to observe the breakup of a liquid jet in a crossflow of air under a variety of conditions. The experimental system was designed to provide well-controlled conditions with minimal amounts of turbulence in the liquid jet and the gaseous crossflow. A variety of Weber num

Age- and time-dependent changes in cancer incidence among immigrants to Sweden: colorectal, lung, breast and prostate cancers

To examine the role of gender, age at immigration and length of stay on incidence trends of common cancers, we studied risk of colorectal, lung, breast and prostate cancers in immigrants to Sweden from 1958 to 2008. The nationwide Swedish Family-Cancer Database was used to calculate standardized incidence ratios for common cancers among immigrants compared to Swedes. Immigrants were classified int

Molecular imprinting of protein in Pickering emulsion.

A new strategy of molecular imprinting to prepare spherical hydrogels via water-in-oil Pickering emulsion polymerization was developed. The imprinted hydrogels exhibited fast adsorption kinetics and significant selectivity for the target protein.

Experimental wavelengths for intrashell transitions in tungsten ions with partially filled 3p and 3d subshells

Spectra and measured wavelengths of intrashell n = 3 transitions in highly charged tungsten ions with partially filled 3p and 3d valence shells, Al-like W61+ through Fe-like W48+, are presented. The ions were created and excited at the electron-beam ion-trap facility at the Lawrence Livermore National Laboratory and measured with a high-resolution grazing-incidence spectrometer. The spectral lines

A reflection on Richard B. Saltman 'Structural patterns in Swedish health policy

Looking back over 30 years of Swedish health care, professor Saltman examines structural changes in the Swedish health care sector. This is a very welcome contribution to the literature, and it makes good sense – institutional change is often a slow process, and it may take considerable time before the effects can be fully appreciated. Saltman’s paper provides a useful analytical overview of thre

Association Between the SVS/AAVS Anatomical Severity Grading Score and Operative Outcomes in Fenestrated Endovascular Repair of Juxtarenal Aortic Aneurysm.

Purpose : To evaluate the association between the Society for Vascular Surgery/American Association for Vascular Surgery (SVS/AAVS) anatomical severity grading (ASG) score and operative outcomes in fenestrated endovascular repair (f-EVAR) for juxtarenal aortic aneurysm. Methods : A review was conducted of all patients treated at our clinic with commercially available, custom-made f-EVAR devices be

Process engineering for bioflavour production with metabolically active yeast - a minireview.

Flavours are biologically active molecules of large commercial interest in the food, cosmetics, detergent and pharmaceutical industry. The production of flavours can take place by either extraction from plant materials, chemical synthesis, through biological conversion of precursor molecules or through de novo biosynthesis. The latter alternatives are gaining importance through the rapidly growing

Hybrid Iterative Reconstruction Algorithm Improves Image Quality in Craniocervical CT Angiography.

OBJECTIVE. The purpose of this study was to evaluate the potential of a hybrid iterative reconstruction algorithm for improving image quality in craniocervical CT angiography (CTA) and to assess observer performance. SUBJECTS AND METHODS. Thirty patients (mean age, 58 years; range 16-80 years) underwent standard craniocervical CTA (volume CT dose index, 6.8 mGy, 2.8 mSv). Images were reconstructed

Reductions in microbial biomass along disturbance gradients in a semi-natural grassland

Soil disturbance is a common phenomenon in semi-natural sandy grasslands, caused by management practices, livestock trampling and erosion. To better understand ecosystem processes when the surface layers of the soil are disturbed, we investigated the effects of disturbance on different functional microbial groups by the use of signature fatty acid analysis. Four levels of disturbance were investig

Diurnal dung beetles use the intensity gradient and the polarization pattern of the sky for orientation.

To escape competition at the dung pile, a ball-rolling dung beetle forms a piece of dung into a ball and rolls it away. To ensure an their efficient escape from the dung pile, the beetles rely on a celestial compass to move along a straight paths. Here, we analyzed the reliability of different skylight cues for this compass and found that dung beetles rely not only on the sun, but also on the skyl

Immunolocalization of Collagens (I and III) and Cartilage Oligomeric Matrix Protein in the Normal and Injured Equine Superficial Digital Flexor Tendon

This is a descriptive study of tendon pathology with different structural appearances of repair tissue correlated to immunolocalization of cartilage oligomeric matrix protein (COMP) and type I and III collagens and expression of COMP mRNA. The material consists of nine tendons from seven horses (5-25 years old; mean age of 10 years) with clinical tendinopathy and three normal tendons from horses (

In vivo cytochrome and alternative pathway respiration in leaves of Arabidopsis thaliana plants with altered alternative oxidase under different light conditions

The in vivo activity of the alternative pathway (V-alt) has been studied using the oxygen isotope fractionation method in leaves of Arabidopsis thaliana modified for the expression of the AtAOX1a gene by anti-sense (AS-12) or overexpression (XX-2). Under non-stressful conditions, V-alt was similar in all plant lines regardless of its different alternative pathway capacities (V-alt). Total leaf res
