Concanavalin A was covalently bound to porous silica (100-1000 Å) by three different coupling procedures. The performance of the preparations was evaluated from their ability to resolve a mixture of closely related sugars. The Concanavalin A-silica was used for efficient and rapid (5-20 min) analysis/purification of samples containing the glucoproteins peroxidase and glucose oxidase. Such columns
Lactate dehydrogenase has been purified by precipitation with a bis-ligand. The precipitating agent in this case was Bis-NAD. This approach of affinity precipitation is also applicable to other enzymes.
The reactive triazine dye, Cibacron Blue F3G-A, has been covalently attached to microparticulate porous silica and used for the resolution of a number of complementary proteins by high-performance liquid affinity chromatography (HPLAC). Cibacron Blue F3G-A was converted to its 6-aminohexyl derivative by reaction with 1,6-diaminohexane and coupled to γ-glycidoxypropyltrimethoxysilane-activated poro
Three methods were developed for preparing alginate gels containing cells that are stable in phosphate containing media. In Method I preformed alginate beads containing entrapped cells were treated with polyethyl eneimine followed by glutaraldehyde. In Method II alginate sol was treated with a carbodiimide and N-hydroxysuccinimide (to form active esters), mixed with cells and extruded into calcium
This chapter aims to enhance our understanding of the implications international standardisation have for audit innovation at the national level. The study analyses the ways in which transnational regulation effectuates institutional constraints on audit innovation in Sweden as a setting to discuss the capacity for the audit profession to innovate and make audits more socially relevant. Based on d
Complement-mediated kidney diseases are ultrarare conditions characterized by excess complement activation related in most cases to complement gene variants or circulating autoantibodies. These conditions are chronic and can lead to kidney failure. They include atypical hemolytic uremic syndrome (aHUS), C3 glomeru-lopathy (C3G), and, to a certain extent, immune complex-membranoproliferative glomer
Freight transportation security concerns both public and private sector institutions, yet their interests are often misaligned, resulting in tensions and trade-offs between performance criteria. Previous research overlooks the connection of public and private interests and provides a fragmented view of the institutions that impact operational conditions and performance within freight transportatioFreight transportation security concerns both public and private sector institutions, yet their interests are often misaligned, resulting in tensions and trade-offs between performance criteria.

I det här kapitlet beskrivs och diskuteras hur utvecklingen av etiska reglerför revisorer har skett i samverkan med utvecklingen av branschen ochsamhället. Det framgår hur regler använts för att disciplinera revisorernaoch för att öka intressenternas förtroende när det behövts för att stärkaden professionella legitimiteten och yrkets status i samhället.
Background: Peripheral nerve injuries cause substantial problems when not treated properly. A specific problem is reconstruction of nerve defects, which can be treated in different ways. This study aimed to systematically review whether processed nerve allograft (PNA) is justified in reconstruction of a nerve defect in patients after posttraumatic or iatrogenic peripheral nerve injury and to compa
The trimeric caffeic acid derivative pulcaffeate (1) was isolated from the organic crude extract of the roots of Bourreria pulchra (Boraginaceae). The biosynthesis of 1 appears to involve an intramolecular Diels-Alder reaction between a cyclohexa-1,3-diene intermediate, generated by the oxidation of the aromatic ring of a cinnamic acid unit, and the conjugated double bond of a caffeic acid unit. T
Sex chromosomes have evolved repeatedly across the tree of life and often exhibit extreme size dimorphism due to genetic degeneration of the sex-limited chromosome (e.g. the W chromosome of some birds and Y chromosome of mammals). However, in some lineages, ancient sex-limited chromosomes have escaped degeneration. Here, we study the evolutionary maintenance of sex chromosomes in the ostrich (Stru
Objective. The aim was to theoretically and experimentally investigate recovery in SPECT images with objects of different shapes. Furthermore, the accuracy of volume estimation by thresholding was studied for those shapes. Approach. Nine spheres, nine oblate spheroids, and nine prolate spheroids phantom inserts were used, of which the six smaller spheres were part of the NEMA IEC body phantom and
Monika Class reflects on some of the theoretical underpinnings of a translational, post-pandemic medical humanities and suggests that the concept of “material translation” might offer a productive way forward.
Artikel på danska om skandalen när kung Valdemar av Sverige blev förälskad i sin svägerska Jutta av Danmark.Historien om en svensk konge og en dansk prinsesse, hvis forelskelse i hinanden var med til at udløse borgerkrigen, der rev Sverige i stykker
We present a combined geomorphologic, multispectral, and geochemical analysis of crater floor rocks in Jezero crater based on data obtained by the Mast Camera Zoom and SuperCam instruments onboard the NASA Mars 2020 Perseverance rover. The combined data from this analysis together with the results of a comparative study with geologic sites on Earth allows us to interpret the origins of rocks expos
