Application of a pH responsive multimodal hydrophobic interaction chromatography medium for the analysis of glycosylated proteins.

Protein glycosylation has significant effects on the structure and function of proteins. The efficient separation and enrichment of glycoproteins from complex biological samples is one key aspect and represents a major bottleneck of glycoproteome research. In this paper, we have explored pH multimodal hydrophobic interaction chromatography to separate glycosylated from non-glycosylated forms of pr

Electron-Beam Patterning of Polymer Electrolyte Films To Make Multiple Nanoscale Gates for Nanowire Transistors

We report an electron-beam based method for the nanoscale patterning of the poly(ethylene oxide)/LiClO4 polymer electrolyte. We use the patterned polymer electrolyte as a high capacitance gate dielectric in single nanowire transistors and obtain subthreshold swings comparable to conventional metal/oxide wrap-gated nanowire transistors. Patterning eliminates gate/contact overlap, which reduces para

Associations of hormone replacement therapy and oral contraceptives with risk of colorectal cancer defined by clinicopathological factors, beta-catenin alterations, expression of cyclin D1, p53, and microsatellite-instability

BACKGROUND: Postmenopausal hormone therapy (HRT) and oral contraceptive (OC) use have in several studies been reported to be associated with a decreased colorectal cancer (CRC) risk. However, data on the association between HRT and OC and risk of different clinicopathological and molecular subsets of CRC are lacking. The aim of this molecular pathological epidemiology study was therefore to evalua

The influence of solid/liquid separation techniques on the sugar yield in two-step dilute acid hydrolysis of softwood followed by enzymatic hydrolysis.

ABSTRACT: BACKGROUND: Two-step dilute acid hydrolysis of softwood, either as a stand-alone process or as pretreatment before enzymatic hydrolysis, is considered to result in higher sugar yields than one-step acid hydrolysis. However, this requires removal of the liquid between the two steps. In an industrial process, filtration and washing of the material between the two steps is difficult, as it

Non-coding RNAs revealed during identification of genes involved in chicken immune responses

Recent large-scale cDNA cloning studies have shown that a significant proportion of the transcripts expressed from vertebrate genomes do not appear to encode protein. Moreover, it was reported in mammals (human and mice) that these non-coding transcripts are expressed and regulated by mechanisms similar to those involved in the control of protein-coding genes. We have produced a collection of cDNA

Residual Stresses in Inertia-Friction-Welded Dissimilar High-Strength Steels

The welding of dissimilar alloys is seen increasingly as a way forward to improve efficiencies in modern aeroengines, because it allows one to tailor varying material property demands across a component. Dissimilar inertia friction welding (IFW) of two high-strength steels, Aermet 100 and S/CMV, has been identified as a possible joint for rotating gas turbine components and the resulting welds are

Robot Joint Modeling and Parameter Identification Using the Clamping Method

The usage of industrial robots for milling tasks is limited by their lack of absolute accuracy in presence of process forces. While there are techniques and products available for increasing the absolute accuracy of free-space motions, the mechanical weaknesses of the robot in combination with the milling forces limits the achievable performance. If the dynamic effects causing the deviations can b

Perceived Severity of Visually Accessible Fires

Investigations of past fires suggest that building occupants faced with a fire have problems defining the severity of it, especially in the early stages of the fire. An experiment was therefore carried out to study people’s ability to estimate fire growth, and their perceived ability to extinguish a fire using a portable fire extinguisher. A total of 535 persons, namely 304 men and 231 women, were

Importance of renal function in cardiac surgery

Popular Abstract in Swedish Njurfunktion inom hjärtkirurgi Akut njursvikt (AKI) efter hjärtkirurgi är en allvarlig komplikation som förekommer i 25-35 % av alla patientfall. AKI medför förhöjd risk för allvarliga komplikationer och död efter hjärtkirurgi. Ett stort fokus ligger på detektion, prevention och behandling av AKI och forskningsfältet uppdateras kontinuerligt. En rad olika läkemedel har Abstract Acute kidney injury (AKI) is a common and serious complication after cardiothoracic surgery and is associated with increased short- and long-term mortality risk. Despite extensive studies in the field, a comprehensive understanding of this syndrome has remained elusive, partly due to divergent definitions of AKI and partly due to the limitations of available routine biomarkers to predict,

On the synthesis of ultra-flat ITO thin films by conventional dc magnetron sputtering at RT

Highly transparent, conductive Sn-doped In2O3 (ITO) thin films with a characteristic root mean square surface roughness RMS below 1 nm were obtained from deposition of amorphous ITO and subsequent annealing treatment. ITO thin films with ultra flat surface were produced by (i) controlling crystallization mechanisms (nucleation and growth) of amorphous ITO through optimization of hydrogen content a

Does Practice Make Perfect? Craft Expertise as a Factor in Aggrandizer Strategies

The focus of this article is on exploring craft expertise and its potential as a factor in aggrandizer strategies. It is argued that there are elements of natural aptitude which enabled certain individuals to excel at flintknapping, allowing them to create objects of exceptional size and beauty in acts of elaborate knapping. Practice alone will enable an individual to reach a certain level of prof

The pentraxin serum amyloid P component is found in the male genital tract and attached to spermatozoa

Serum amyloid P component (SAP) belongs to the pentraxin family of proteins, members of which are characterized by radial pentameric structure and calcium-dependent ligand binding. SAP is present in all types of amyloidosis and has been shown to bind to several ligands, but the physiological function of this protein has not been fully elucidated. The present study identified and characterized SAP

Genetic variants for liver fat accumulation and circulating triglyceride levels

Non-alcoholic fatty liver disease (NAFLD), obesity and type 2 diabetes(T2D) are strongly associated and today their prevalence reaches epidemic proportions. NAFLD has a multi-factorial aetiology, both genetic and environmental factors are equally important. The aim of this thesis was to investigate genetic factors associating with NAFLD and circulating triglyceride (TG) levels in overweight or obe

Evidence for reduced collectivity around the neutron mid-shell in the stable even-mass Sn isotopes from new lifetime measurements

Precise measurements of the lifetimes of the first excited 2(+) states in the stable even-A Sn isotopes Sn112-124 have been performed using the Doppler shift attenuation technique. For the isotopes Sn-112, Sn-114 and Sn-116 the E2 transition strengths deduced from the measured lifetimes are in disagreement with the previously reported values and indicate a shallow minimum at N = 66. The observed d

Polarized neutron powder diffraction studies of antiferromagnetic order in bulk and nanoparticle NiO

In many materials it remains a challenge to reveal the nature of magnetic correlations, including antiferromagnetism and spin disorder. Revealing the spin structure in magnetic nanoparticles is further complicated by the large incoherent neutron scattering cross section from water adsorbed at the particle surfaces and by the broadening of diffraction peaks due to the finite crystallite size.
