Hyperglycemia in Extremely Preterm Infants—Insulin Treatment, Mortality and Nutrient Intakes

Objective: To explore the prevalence of hyperglycemia and the associations between nutritional intakes, hyperglycemia, insulin treatment, and mortality in extremely preterm infants. Study design: Prospectively collected data from the Extremely Preterm Infants in Sweden Study (EXPRESS) was used in this study and included 580 infants born 180 mg/dL (10 mmol/L) of up to 30% was observed during the fi

Targeting of retroviral vectors through protease-substrate interactions

Targetable, injectable vectors would greatly facilitate the development of in vivo therapy strategies. Viral and nonviral vectors can be targeted through ligand-receptor interactions, but protease-substrate interactions have not previously been exploited for vector targeting. Epidermal growth factor (EGF) was fused to a retroviral envelope glycoprotein via a cleavable linker comprising a factor Xa

Improvement of retroviral retargeting by using amino acid spacers between an additional binding domain and the N terminus of Moloney murine leukemia virus SU

We previously reported a strategy to redirect the retroviral host range by expressing single-chain antibodies (S. J. Russell, R. E. Hawkins, and G. Winter, Nucleic Acids Res. 21:1081-1085, 1993) or ligands (F.-L. Cosset, F. J Morling, Y. Takeuchi, R. A. Weiss, M. K. L. Collins, and S. J. Russell, J. Virol. 69:6314-6322, 1995) at the N terminus of Moloney murine leukemia virus (MoMLV) surface prote

Retroviral display of antibody fragments; interdomain spacing strongly influences vector infectivity

Five different single-chain antibody fragments (scFv) against human cell-surface antigens were displayed on murine ecotropic retroviral vectors by fusing them to the Moloney SU envelope glycoprotein. The spacing between the scFv and the SU glycoprotein was varied by fusing the scFv to residue +7 or to residue +1 of Moloney SU and by inserting linker sequences of different lengths between the domai

On the interaction between single chain Fv antibodies and bacterial immunoglobulin-binding proteins

Using four bacterial immunoglobulin-binding proteins, we have analyzed the binding characteristics of a panel of 34 human single chain Fv antibodies, expressed in E. coli and with known specificity and sequence. Several of the single chain Fv antibodies showed affinity for staphylococcal protein A and peptostreptococcal protein L, but not for the streptococcal proteins G or H. The affinity of the

On the interaction between protein L and immunoglobulins of various mammalian species

Protein L, a cell wall molecule of certain strains of the anaerobic bacterial species Peptostreptococcus magnus, shows high affinity for human immunoglobulin (Ig) light chains. In the present study protein L was tested against a panel of human myeloma proteins of the IgG, IgM, IgA and IgE classes, and strong binding was seen with antibodies carrying kappa light chains. A high degree of specificity

Purification of antibodies using protein L-binding framework structures in the light chain variable domain

Protein L from the bacterial species Peptostreptococcus magnus binds specifically to the variable domain of Ig light chains, without interfering with the antigen-binding site. In this work a genetically engineered fragment of protein L, including four of the repeated Ig-binding repeat units, was employed for the purification of Ig from various sources. Thus, IgG, IgM, and IgA were purified from hu

Protein L from Peptostreptococcus magnus binds to the kappa light chain variable domain

Protein L is an immunoglobulin light chain-binding protein expressed by some strains of the anaerobic bacterial species Peptostreptococcus magnus. The major variable region subgroups of human kappa and lambda light chains were tested for protein L binding; V kappa I, V kappa III, and V kappa IV bound protein L, whereas no binding occurred with proteins of the V kappa II subgroup or with any lambda

Antibody response in immunized rabbits measured with bacterial immunoglobulin-binding proteins

Protein G, an immunoglobulin (Ig)-binding protein isolated from group C or G streptococci, binds to the Fc portion of IgG. Protein L, from the anaerobic bacterium Peptostreptococcus magnus, specifically binds light chains of Ig. In this study, protein G and L were used to measure the production of antibodies in immunized rabbits. Two rabbits were immunized with a mixture of human urinary proteins

Enzyme linked immunosorbent assay using alkaline phosphatase conjugated with streptococcal protein G

Protein G, an IgG-binding protein, purified from the surface of group G streptococci, was coupled to alkaline phosphatase. The conjugate was used for detection of polyclonal goat and rabbit antibodies and monoclonal mouse IgG1, IgG2a and IgG2b in an enzyme-linked immunosorbent assay. A two-step coupling procedure was used, in which glutaraldehyde was allowed to react with the enzyme, excess glutar

Detection and purification of rat and goat immunoglobulin G antibodies using protein G-based solid-phase radioimmunoassays

Using the newly described streptococcal surface protein, protein G, which has powerful immunoglobulin G binding properties, solid-phase radioimmunoassays were developed for the quantitation of goat and rat immunoglobulin G bound to the plastic surface of microtiter plates. The binding of goat immunoglobulin G to the surface via a specific antigen (guinea pig alpha 1-microglobulin) permitted the de

Hip Heritage and Heritage Pasts : Tensions when re-fashioning museum culture

When museums of cultural heritage are no longer defined solely in terms of their collections and cultural environments, how much may they change before they cease to be museums and what do they become then? As a means of approaching this question this chapter focuses on two institutions of Swedish cultural heritage, The American Swedish Institute (ASI) in Minneapolis, Minnesota and Kulturen in Lun

Arbetslivets omreglering, arbetsmarknadens reglering och lärlingsutbildningens betydelse

I kapitlet är syftet att vidga perspektivet på regleringar och diskutera den omreglering som har skett i arbetslivet under de tre-fyra senaste decennierna. Förändringarna i arbetslivet hänger samman med nya konkurrensvillkor, ny teknik och förändrade arbetsorganisationer. Det handlar om en utveckling bort från det som brukar kallas industrisamhället till det post-industriella samhället. Hur påverk

Morphometric analysis of inter‐ and intraspecific variation in the Cambrian helcionelloid mollusc Mackinnonia

Phylogenetic relationships within the helcionelloid molluscs have been difficult to establish. One of the reasons for this is that qualitative approaches to investigating morphological variation in this group have struggled to identify clear patterns. An alternative method of identifying these patterns is to study these organisms quantitatively. Here this approach is exemplified by employing morph
