HYPERACUTE rejection (HAR) of the kidney was first recognized 20 years ago in cases of donor-recipient incompatibility for the major blood group and tissue antigen systems. I•3 Recently, three patients at the University of Pittsburgh developed immediate graft dysfunction after receiving a kidney from an ABO-compatible cadaveric donor with a negative warm lymphocytotoxic crossmatch. None of the ...

Syftet med det här arbetet har varit att utveckla en praktisk Man-In-The-Middle-attack mot trådlösa klienter på NetLogon-systemet vid Linköpings Universitet. Målsättningen har varit att attacken skall ske så transparent som möjligt ur offrets synvinkel. Attacken använder DNS-spoofing och en MITM-metod med förfalskade avsändaradresser genom packet injection. Vi har implementerat ett fungerande v...

The current generation of handheld devices have substantially greater processor speeds and graphics capabilities than the previous generation. With these gains, handheld devices have crossed an important technological threshold. It is now possible to blend the methods and practices used to create larger scale Augmented Reality (AR) experiences with those used to design handheld games. Handheld ...

Through empirical research is identified that the hypothesis of normal distribution of returns is no longer observed while verifying the existence of heavy tails and asymmetries in the distribution. Thus, the article has aimed empirically apply copula models using techniques of realized volatility (HAR) with high-frequency data and perform the calculation of Value at Risk for different periods....

Den här uppsatsen behandlar ett antal individer begravda mellan 800 e.Kr. och 1150 e.Kr i ett tidigt kristet gravfält kring ruinen av Varnhems gårdskyrka. Av speciellt intresse är den placeringen som gravarna har i förhållande till kyrkomurarna och vad dessa placeringar innebär statusmässigt. Analys av stabila isotoper har därför utförts på de manliga individerna så att deras diet kan faställas...

Rejections caused by xenotransplantation Transplantation between two different species may give rise to two types of graft rejection. Between so-called discordant species a hyperacute rejection (HAR) occurs within minutes or hours. In so-called concordant species this type of rejection does not occur, but over days a delayed xenograft rejection (DXG) (6) will occur. In all transplanted organs, ...

We describe an 11 year old girl with a de novo unbalanced t(X;10) that resulted in a deletion of Xq26-->Xqter and a trisomy of 10q21-->10qter. Her clinical features were of distal trisomy 10q, but she lacked the cardiovascular and renal malformations observed in duplications of 10q24-->10qter and had only moderate mental retardation. X inactivation was assessed on peripheral blood lymphocytes b...

THE INITIAL barrier to successful organ xenotrans1. plantation in discordant species is hyperacute rejection (HAR) mediated by either natural (preformed) or induced antibodies. 1•2 Hamster cardiac xenografts are normally rejected by this mechanism within 3 days when transplanted into naive LEW or athymic (nude) rats,3 which in the latter is supposedly caused by a T-cell independent process. Thi...

The acidity and stability constants of M(Trp) M: Cu, Cu(Bpy)2+, and Cu(Phen)2+ complexes, were determined by potentiometric pH titration. It is shown that the stability of the binary Cu(Trp) complex is determined by the basicity of the carboxylate group on one side and amino group on the other side. It is demonstrated that the equilibrium, Cu(Har)2+ + Cu(Trp) Cu(Har)(Trp) + Cu, is displacement ...
