Infrared to visible up-conversion in thulium and holmium doped lutetium aluminum garnet
We report on the up-converted emissions at 367, 458 and 483 nm in thulium doped lutetium aluminum garnet (LuAG) under infrared excitation in the range of 730-800 nm. We also observe blue and strong green emission in thulium and holmium codoped LuAG with near infrared excitation. Excitation spectra, power dependence, temporal behavior and temperature dependence of up-converted emissions were measur
Characterization of non-expressed C4 genes in a case of complete C4 deficiency: identification of a novel point mutation leading to a premature stop codon
The genetic basis of complete C4 deficiency in a patient with SLE was investigated. Previous studies have demonstrated that this patient has two different major histocompatibility complex (MHC) haplotypes that each contain a major deletion and a non-expressed C4 gene. In the present study, non-expression of the C4 genes was explained by the finding of two distinct C4 gene mutations. A previously d
Integrated bioprocess for the production and isolation of urokinase from animal cell culture using supermacroporous cryogel matrices
An integrated cell cultivation and protein product separation process was developed using a new type of supermacroporous polyacrylamide gel, called cryogel (pAAm-cryogel) support matrix. Human fibrosarcoma HT1080 and human colon cancer HCT116 cell lines were used to secrete urokinase (an enzyme of immense therapeutic utility) into the culture medium. The secreted protein was isolated from the circ
Atmospheric mercury near a chlor-alkali plant in Sweden
Atmospheric mercury species/fractions were measured near a chlor-alkali plant in Sweden during August 28 to September 4, 2001. The concentration of total gaseous mercury in the plume from the plant was measured using TEKRAN and GARDIS instruments. Gaseous elemental mercury was measured using a light detection and ranging (LIDAR) technique. From vertical LIDAR sweeps through the plume from the chlo
A key recovery attack on Edon80
Edon80 is a recent stream cipher design that has advanced to the third and last phase of the eSTREAM project. It has remained unbroken and untweaked since it was designed and submitted to eSTREAM. It is now one of the 8 final hardware candidates. In this paper we cryptanalyze the cipher by describing a key recovery attack. The complexity of the attack is around 269 simple operations for a keystrea
Differential activation of signal transducer and activator of transcription (STAT)3 and STAT5 and induction of suppressors of cytokine signalling in T(h)1 and T(h)2 cells
Cytokines direct the differentiation of naive CD4(+) T cells into either IFN-gamma-producing T(h)1 cells or IL-4-producing T(h)2 cells. In this study, we analyzed the activation of signal transducer and activator of transcription (STAT)1, STAT3 and STAT5 (together with STAT4 and STAT6), and the expression of the recently identified suppressor of cytokine signalling (SOCS) proteins, in differentiat
A differential difference comparator for multi-step A/D converters
The proposed Differential Difference Comparator (DDC) provides easy linear voltage summing/subtraction and comparison functions via current operation. The speed of this unconventional comparator drastically improved since there is no feedback loop and coupling capacitors needed to maintain the linearity. The linear input range is also enlarged by the common mode compression. The principle, design

Atrial Fibrillation Following Out-of-Hospital Cardiac Arrest and Targeted Temperature Management - Are We Giving It the Attention it Deserves?
Objectives: Atrial fibrillation has been associated with increased mortality in the general population and mixed populations of critical ill. Atrial fibrillation can also affect patients during post-cardiac arrest care. We sought to assess the prognostic implications of atrial fibrillation following out-of-hospital cardiac arrest, including relation to the level of targeted temperature management.
Agent of change : street art and environmental thinking
This paper applied an ecocritical perspective on street art to expand on the notion that street art can have an impact on how we relate to urban public space. In doing so, it argued that street art is particularly well positioned to affect the way we think and act with regard to the environment.

Oxidative stress, inflammation and treatment response in major depression
OBJECTIVE: Increased inflammation and oxidative stress have been shown in Major Depressive Disorder (MDD), although there is significant heterogeneity across studies. Whether markers of inflammation and oxidative stress are associated with antidepressant treatment response in MDD is currently unclear. The goals of the present study are to investigate markers of inflammation and oxidative stress in
Rational and evolutionary engineering of Saccharomyces cerevisiae for production of dicarboxylic acids from lignocellulosic biomass and exploring genetic mechanisms of the yeast tolerance to the biomass hydrolysate
Background: Lignosulfonates are significant wood chemicals with a $700 million market, produced by sulfite pulping of wood. During the pulping process, spent sulfite liquor (SSL) is generated, which in addition to lignosulfonates contains hemicellulose-derived sugars—in case of hardwoods primarily the pentose sugar xylose. The pentoses are currently underutilized. If they could be converted into v
Natural killer cell activity and antibody-dependent cellular cytotoxicity in newborn infants
The ability of lymphocytes from the peripheral blood of preterm and term infants and adult women and men to mediate natural killing (NK) and K cell activity (antibody-dependent cellular cytotoxicity) was analysed in 4 hours 51Cr-release assays. K 562 cells were targets for NK activity. K cell activity was assayed on antibody-coated rat thymocytes. Lymphocytes from adult male donors were significan

The impact of dermoscopy on melanoma detection in the practice of dermatologists in Europe : results of a pan-European survey
BACKGROUND: Dermoscopy is a widely used technique that can increase the sensitivity and specificity of melanoma detection. Information is lacking on the impact of dermoscopy use on the detection of melanoma in the real-life practice of European dermatologists.OBJECTIVE: To identify factors that influence the benefit of using dermoscopy for increasing melanoma detection and lowering the number of u
Rates of RLN and SLN injury : Data from national quality registries and the literature
The impact of thyroid surgery on voice is a key performance indicator of surgical quality. This chapter discusses factors that can impact on the incidence of both recurrent and external laryngeal nerve (external branch of superior laryngeal nerve-EBSLN) injury. The literature is reviewed and reported incidence of nerve palsy following thyroid surgery is presented. Particular reference is made to t
Transport efficiency of packaging in food supply chains : - Does it matter in a life cycle perspective?
Purpose: Packaging adds weight and volume to food products, thereby increasing the environmental impact of transport processes. This research examines the relative importance of transport efficient packaging in food supply chains that rely on road transport compared to other environmental requirements, such as packaging material minimization and food waste reduction.Design/methodology/approach: Sc
