Affinity screening for weak monoclonal antibodies

When selecting for monoclonal antibodies of a desired affinity, affinity chromatography can be a feasible alternative. This is of particular interest when low affinity monoclonal antibodies (dissociation constant (Kd) > 10(-4) M) are screened, as they are not easily recognised by traditional immunoassay procedures. In this study we have evaluated this approach by monitoring low affinity monoclonal

Renal dysfunction after total knee replacement is not aggravated by bone cement

Background: Total knee replacement (TKR) has been associated with postoperative renal dysfunction. The use of monomeric methylmethacrylate (MMA) bone cement causes hypotension by several mechanisms. Methods: In 30 patients undergoing TKR with (n=16), or without (n=14) bone cement, serum levels of creatinine, cystatin C and creatine kinase (CK) and urinary levels of creatinine and markers for glome

The increase of plasma homocysteine concentrations with age is partly due to the deterioration of renal function as determined by plasma cystatin C

One of the main determinants of plasma homocysteine in healthy subjects is serum creatinine. In the present study, we therefore investigated the relation between plasma homocysteine concentration, serum creatinine and a new marker for glomerular filtration rate, plasma cystatin C concentration. Cystatin C reflects the glomerular filtration better than serum creatinine and is not related to the mus

The changing landscape of genetic testing and its impact on clinical and laboratory services and research in Europe

The arrival of new genetic technologies that allow efficient examination of the whole human genome (microarray, next-generation sequencing) will impact upon both laboratories (cytogenetic and molecular genetics in the first instance) and clinical/medical genetic services. The interpretation of analytical results in terms of their clinical relevance and the predicted health status poses a challenge

The Rhetorical Handling and Construction of Uncertainty in Tax Litigation Concerning Valuation of Financial Instruments

A tax litigation concerning the value of non-traded financial instruments is impregnated by uncertainty. The aim of this paper is to study how uncertainty inherent in financial valuation models is discursively and rhetorically handled and constructed by the litigating parties as well as the court. A discourse analysis guided by the notion of hedging is conducted on The Swedish Tax Agency v. PwC (2A tax litigation concerning the value of nontraded financial instruments is impregnated by uncertainty. The aim of this paper is to study how uncertainty inherent in financial valuation models is discursively and rhetorically handled and constructed by the litigating parties aswell as the court.

Trafikolyckor med traktorer : Trafiksäkerhet med fokus på yngre och äldre förare

Lantbruket rankas konsekvent som en av de mest riskfyllda sektorerna i Sverige såväl som i många andra delar av världen. Förutom lidande för den enskilde beräknas dödliga och icke dödliga skador i svenskt lantbruk kosta samhället 2 – 3 miljarder kr per år. I Sverige inträffade det cirka 5 000 olyckor på jordbruksföretag 2004. Detta innebar att minst en olycka inträffade på 8% av svenska gårdar som

Kaon–proton strong interaction at low relative momentum via femtoscopy in Pb–Pb collisions at the LHC

In quantum scattering processes between two particles, aspects characterizing the strong and Coulomb forces can be observed in kinematic distributions of the particle pairs. The sensitivity to the interaction potential reaches a maximum at low relative momentum and vanishing distance between the two particles. Ultrarelativistic heavy-ion collisions at the LHC provide an abundant source of many had

First measurements of N-subjettiness in central Pb-Pb collisions at √sNN = 2.76 TeV

The ALICE Collaboration reports the first fully-corrected measurements of the N-subjettiness observable for track-based jets in heavy-ion collisions. This study is performed using data recorded in pp and Pb-Pb collisions at centre-of-mass energies of s = 7 TeV and sNN = 2.76 TeV, respectively. In particular the ratio of 2-subjettiness to 1-subjettiness, τ2/τ1, which is sensitive to the rate of two

Search for dark matter in events with missing transverse momentum and a Higgs boson decaying into two photons in pp collisions at √s = 13 TeV with the ATLAS detector

A search for dark-matter particles in events with large missing transverse momentum and a Higgs boson candidate decaying into two photons is reported. The search uses 139 fb−1 of proton-proton collision data collected at s = 13 TeV with the ATLAS detector at the CERN LHC between 2015 and 2018. No significant excess of events over the Standard Model predictions is observed. The results are interpre

Proteinuria selectivity index based upon alpha 2-macroglobulin or IgM is superior to the IgG based index in differentiating glomerular diseases. Technical note

BACKGROUND: The proteinuria selectivity index (SI) may be used to describe changes of the glomerular permeability for macromolecules in glomerular diseases. Proteins the size of alpha 2-macroglobulin (alpha 2 M) or IgM cannot normally pass the glomerular barrier, whereas IgG can pass through the large pores of glomerular basement membrane. Comparison of the clearance of the three high-molecular-we

Facial mimicry in the congenitally blind

Imitation is one of the core building blocks of human social cognition, supporting capacities as diverse as empathy, social learning, and knowledge acquisition1. Newborns’ ability to match others’ motor acts, while quite limited initially, drastically improves during the first months of development2. Of notable importance to human sociality is our tendency to rapidly mimic facial expressions of em

Rheumatoid arthritis : A gene transfer disease

Sera from patients with rheumatoid arthritis (RA) were from the very start instrumental in detecting and delineating the human immunoglobulin (Ig) allotypes in the Gm system. Knowledge that human Ig production is under Mendelian control and not determined by templates of antigen would not have come to the fore if it were not for RA patients. Worldwide experience shows that RA patients are prone to

Cystatin C deficiency in human atherosclerosis and aortic aneurysms

The pathogenesis of atherosclerosis and abdominal aortic aneurysm involves breakdown of the elastic laminae. Elastolytic cysteine proteases, including cathepsins S and K, are overexpressed at sites of arterial elastin damage, but whether endogenous local inhibitors counterbalance these proteases is unknown. We show here that, whereas cystatin C is normally expressed in vascular wall smooth muscle

Urine IgG2/IgG4-ratio indicates the significance of the charge selective properties of the glomerular capillary wall for the macromolecular transport in glomerular diseases

BACKGROUND: Alterations of the charge-selective properties of the glomerular capillary wall are important constituents of the pathogenesis of many glomerular diseases. Thus, differences in the degree of such changes could be of help in understanding the mechanisms governing the transport of macromolecules across the glomerular capillary wall.METHODS: The ratio between urine concentrations of neutr
