Heparin binding protein in patients with acute respiratory failure treated with granulocyte colony-stimulating factor (filgrastim) - a prospective, placebo-controlled, double-blind study

Background: Heparin Binding Protein (HBP) is released to blood circulation from activated neutrophils in bacterial infections. It is a potential inducer of vascular leakage and precludes the development of septic shock. Filgrastim induces the production of new neutrophils and modulates their bacterial-killing activity. We evaluated the effect of filgrastim on HBP -concentrations in critically ill

Functional Modeling of Genes Upregulated in Chronic Myeloid Leukemia

Chronic myeloid leukemia (CML) is caused by the transformation of a primitive hematopoietic cell by the BCR/ABL1 fusion gene that is formed through the chromosomal translocation t(9;22). CML is currently successfully treated with tyrosine kinase inhibitors targeting the ABL1 kinase domain. However, the CML stem cells are insensitive to this drug and a large fraction of patients will have relapse f

Increasing the environmental and social sustainability in corporate purchasing: Practices and tools

Despite efforts to stimulate the dissemination of green purchasing practices, their uptake in business and industry has so far proven limited. Reasons for the limited progress remain largely unclear. One factor explored in this thesis, is the role of information in the operationalization and dissemination of green purchasing in organizations and supply chains. The importance of knowledge and infor

Regional wall function before and after acute myocardial infarction; an experimental study in pigs.

Left ventricular function is altered during and after AMI. Regional function can be determined by cardiac magnetic resonance (CMR) wall thickening, and velocity encoded (VE) strain analysis. The aims of this study were to investigate how regional myocardial wall function, assessed by CMR VE-strain and regional wall thickening, changes after acute myocardial infarction, and to determine if we could

The endocrine heart - metabolic actions of atrial natriuretic peptide

Abstract The natriuretic peptides (NPs), namely atrial natriuretic peptide (ANP) and bran natriuretic peptide (BNP), which are secreted from cardiomyocytes in response to cardiac wall stress, play a significant role in the regulation of blood pressure, intravascular volume, and cardiac remodeling. Recently, NPs emerged as hormones with metabolic actions such as inhibition of the renin-angiotensin

Regulated transport as a mechanism for pattern generation: Capabilities for phyllotaxis and beyond

Large-scale pattern formation is a frequently occurring phenomenon in biological organisms, and several local interaction rules for generating such patterns have been suggested. A mechanism driven by feedback between the plant hormone auxin and its polarly localized transport mediator PINFORMED1 has been proposed as a model for phyllotactic patterns in plants. It has been shown to agree with curre

Characterization of the biochemical and biophysical properties of the Saccharomyces cerevisiae phosphate transporter Pho89

In Saccharomyces cerevisiae, Pho89 mediates a cation-dependent transport of Pi across the plasma membrane. This integral membrane protein belongs to the Inorganic Phosphate Transporter (PiT) family, a group that includes the mammalian Na(+)/Pi cotransporters Pit1 and Pit2. Here we report that the Pichia pastoris expressed recombinant Pho89 was purified in the presence of Foscholine-12 and function

Counting the Minutes-Measuring Truck Driver Time Efficiency

How truck drivers spend their time is crucial to the profitability of motor carriers. However, the aspect of time has been marginally addressed in industry practice and academic literature on motor-carrier strategies and operations. Given the importance of the drivers in transport operations, the purpose of this article is to outline how driver time in motor-carrier operations can be measured usin

Underestimation of toluene diisocyanate concentration using long-term sampling with 1-(2-methoxyphenyl) piperazine impregnated filters.

Occupational exposure to toluene diisocyanate (TDI) is a known occupational hazard and the occupational exposure limits in air are very low. One of the most common methods to monitor exposure to isocyanates is to sample air through filters impregnated with 1-(2-methoxyphenyl) piperazine (2MP). In one earlier field study it was found that long-term sampling with 2MP-filters underestimated the expos

InAs nanowire MOSFET differential active mixer on Si-substrate

An active single balanced down-conversion mixer is implemented using InAs nanowire metal oxide semiconductor field effect transistors (MOSFETs) as both active devices and passive resistive loads. Circuits with 6 dB low-frequency voltage gain and a 3 dB bandwidth of 2 GHz are measured for a DC power consumption of 3.8 mW from a 1.5 V supply. The circuits are fabricated using contacts made with 12 μ

Spectroscopic Investigations of Highly Charged Tungsten Ions - Atomic Spectroscopy and Fusion Plasma Diagnostics

Popular Abstract in Swedish Atomspektra har varit ett viktigt forskningsområde inom fysiken sedan mitten av 1800-talet. Då elektromagnetisk strålning, såsom synligt ljus, ultraviolett- och röntgenstrålning, är unik för varje grundämne ger ett observerat spektrum information om vilka slags atomer som emitterar strålningen. Exempelvis så visar spektra av ett vanligt lysrör att ljuset kommer från kviThe spectra of highly charged tungsten ions have been investigated using x-ray and extreme ultraviolet spectroscopy. These heavy ions are of interest in relativistic atomic structure theory, where high-precision wavelength measurements benchmark theoretical approaches, and in magnetic fusion research, where the ions may serve to diagnose high-temperature plasmas. The work details spectroscopic in

Gold- and silver nanoparticles affect the growth characteristics of human embryonic neural precursor cells.

Rapid development of nanotechnologies and their applications in clinical research have raised concerns about the adverse effects of nanoparticles (NPs) on human health and environment. NPs can be directly taken up by organs exposed, but also translocated to secondary organs, such as the central nervous system (CNS) after systemic- or subcutaneous administration, or via the olfactory system. The CN
