An accurate and reasonable technique combining direct absorption spectroscopy and laser-induced fluorescence (LIF) methods is developed to quantitatively measure the concentrations of hydroxyl in CH4/air flat laminar flame. In our approach, particular attention is paid to the linear laser-induced fluorescence and absorption processes, and experimental details as well. Through measuring the tempera

This paper analyzes the effects of a multilateral debt relief program on child health. The International Monetary Fund and the World Bank launched the Heavily Indebted Poor Countries Initiative in the late 1990s to reduce the debt burdens of poor countries, and explicitly linked the initiative to the aim of poverty reduction and social targets. As a result, debt-servicing costs have gone down by a

Na+/H+ exchangers are ubiquitous in mammalian cells, carrying out key functions, such as cell volume defense, acid-base homeostasis, and regulation of the cytoskeleton. We used two screening technologies (FLIPR and microphysiometry) to characterize the signal transduction pathway used by the bradykinin beta(2) receptor to activate Na+/H+ exchange in two cell lines, KNRK and CHO. In both cell types

We present a method providing synchronized measurements using the two techniques: quartz crystal microbalance with dissipation (QCM-D) monitoring and localized surface plasmon resonance (LSPR). This was achieved by letting a thin gold film perforated with short-ranged ordered plasmon-active nanoholes act as one of the electrodes of a QCM-D crystal. This enabled transmission-mode optical spectrosco

The most widely used model for rheumatoid arthritis is the collagen-induced arthritis (CIA) in mice. This model has gained acceptance since it is reproducible, well defined and has proven useful for development of new therapies for rheumatoid arthritis, as exemplified by the most recent advancement using TNFalpha neutralization treatment. The collagen-induced arthritis model, however, represents o

Polyamines are essential for tumor cell growth, and the polyamine pathway represents an attractive target for cancer treatment. Several polyamine transport proteins have been cloned and characterized in bacteria and yeast cells; however, the mechanism of polyamine entry into mammalian cells remains poorly defined, although a role for proteoglycans has been suggested. Here, we show that the HIV-Tat

Contemporary value theory has been characterized by a renewed interest in the analysis of concepts like "good" or "valuable", the most prominent pattern of analysis in recent years being the socalled buck-passing or fitting-attitude analysis which reduces goodness to a matter of having properties that provide reasons for pro-attitudes. Here I argue that such analyses are best understood as metaphy

Using quantum dot artificial atoms as a simple toy model, we reflect on the question of whether spin density functional theory (SDFT) can accurately describe correlation effects in low-dimensional fermion systems. Different expressions for the local density approximation of the exchange-correlation energy for the two-dimensional electron gas, such as the much-used functional of Tanatar and Ceperle

BACKGROUND. Androgen deprivation is the only effective systemic therapy available for patients with prostatic carcinoma, but is associated with a gradual transition to a hormone-refractory prostate cancer (HRCAP) in which ligand-independent activation of the androgen receptor has been implicated. The beta(2)-adrenergic receptor (beta(2)-AR) is a well-known activator of the androgen receptor. METHO

The purpose of this study is to investigate how agile development affects collaboration in an organization. Agile processes have received interest from the software development community during the last years as they address changes, such as new customer requirements or re-prioritization of development tasks, which is important to manage in software development. Most of the research published abou

Neuropepticle Y (NPY) prominently inhibits epileptic seizures in different animal models. The NPY receptors mediating this effect remain controversial partially due to lack of highly selective agonists and antagonists. To circumvent this problem, we used various NPY receptor knockout mice with the same genetic background and explored anti-epileptic action of NPY in vitro and in vivo. In Y2 (Y2-/-)

Background. Enteric Helicobacter species might be a risk factor for chronic liver and biliary tract diseases. Aims. To analyse serum antibody levels to three enteric Helicobacter species in patients with various biliary tract and chronic liver diseases and compare results with corresponding parameters for an adult population group, known to have a high prevalence of Helicobacter pylori infection,

GaSb/GaAs quantum dot systems are fabricated using MBE under various growth modes. The as-grown samples are studied with in situ synchrotron radiation XPS covering the As 3d, Sb 4d and Ga 3d core levels and the valence band region. The XPS spectra show dramatic changes with the growth modes, reflecting changes in the local electronic structure and chemical environments of the surface and interface

The purpose of this study was to assess the association between 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) in plasma, a biomarker of exposure to polychlorinated biphenyls (PCB), and time to pregnancy (TTP) in a group of women with a varying dietary exposure to PCB. For 121 Swedish east coast fishermen's wives (median year of birth 1956, range 1945-1968), information on selt-reported TTP for the fi

We present estimates of standardized selection (directional and quadratic) differentials via reproductive success on eight morphological traits in a newly founded long-term study population of great reed warblers Acrocephalus arundinaceus in Sweden. In order to predict the evolutionary response to selection in these traits we present estimates of heritabilities (h(2)), phenotypic (r(P)) and geneti

Background & Aims: Despite treatment with corticosteroids, severe to moderately severe attacks of ulcerative colitis have a high colectomy rate. We intended to find a rescue therapy other than cyclosporin A, which imposes a high risk of side effects and cyclosporine-related mortality. Method : This was a randomized double-blind trial of infliximab or placebo in severe to moderately severe ulce

Objective: Conjunctiva-associated lymphoid tissue is the conjunctival equivalent to mucosa-associated lymphoid tissue (MALT). Mucosa-associated lymphoid tissue lymphoma has been shown to be associated with Helicobacter pylori. In this study, the prevalence and possible role of H. pylori infection in conjunctival MALT lymphoma were evaluated. Design: Retrospective noncomparative case series. Partic

The aim of this study was to investigate the specificity of the H-3-triolein assay and to investigate the recovery of highly purified pancreatic lipase and pancreatic lipase in the form of pure non-activated pig pancreatic juice. Blood plasma from pigs was analysed for pancreatic lipase activity using the H-3-triolein substrate assay, with a method specific for lipoprotein lipase and with a method
