Popular Abstract in Swedish Karl Landsteiner upptäckte blodgruppssystemet ABO och beskrev principen för den antigen-antikroppsreaktion som gäller än idag. För att utföra en säker blodtransfusion krävs det att individens ABO-blodgrupp är känd och därefter kan passande givarblod transfunderas. A- och B-generna ger upphov till enzymen A- respektive B-transferas. Blodgrupp O beror på olika defekter sABO is the most important blood group system in transfusion medicine and transplantation immunology. The ABO blood groups differ by the presence or absence of antigens on RBCs and antibodies in plasma. Accurate determination of ABO status is critical. Genomic typing can increase the precision of blood group determination in complicated cases, e.g. when variant expression of A or B antigen is encou

Perioden från mitten av det första årtusendet av vår tideräkning till mitten av det andra (ca 500-1500) var en tid då det skånska landskapet kom att helt omvandlas, först i och med skapandet av stora aristokratiska gods under periodens början, därefter med en reglering av landskapet i form av bildandet av byar och socknar kring dess mitt.

The entire cDNA corresponding to the C-terminal cysteine-rich domain of the human MUC2 apomucin, after the serine- and threonine-rich tandem repeat, was expressed in Chinese-hamster ovary-K1 cells and in the human colon carcinoma cell line, LS 174T. The C-terminus was expressed as a fusion protein with the green fluorescent protein and mycTag sequences and the murine immunoglobulin K-chain signal

Knee prostheses with metal backing of the polyethylene tibial component are nowadays used almost universally. Eight cases of fracture of the metal tray are reported in the literature. We present a case in which the failure could be expected because of improper design of the tibial tray.

We have shown that electron-spin density can be generated by a dc current flowing across a pn junction with an embedded asymmetric quantum well. Spin polarization is created in the quantum well by radiative electron-hole recombination when the conduction electron momentum distribution is shifted with respect to the momentum distribution of holes in the spin-split valence subbands. Spin current app

The spectroscopic properties of spirilloxanthin in an nhexane solution and bound to the core light-harvesting LH1) complex of Rhodospirillum rubrum were studied by near infrared ultrafast transient absorption spectroscopy. Global analysis of the kinetic traces measured after excitation of spirilloxanthin to the S2 (1Bu +) state enabled us to estimate the species-associated difference spectra that

We have extended the laser probing technique at the CRYRING storage ring to measurement of the extremely long lifetime (28 s) of the metastable 3d2(3P)4s b 4P5/2 level in Ti II. The result obtained demonstrates the power of this method for investigation of such long-lived levels. This is the first experimental lifetime investigation of metastable states in Ti II.

We consider the Euler approximation of stochastic differential equations (SDEs) driven by Levy processes in the case where we cannot simulate the increments of the driving process exactly. In some cases, where the driving process Y is a subordinated stable process, i.e., Y = Z(V) with V a subordinator and Z a stable process, we propose an approximation Y by Z(V-n) where V-n is an approximation of
