Each of 102 Nordic routine clinical biochemistry laboratories collected blood samples from at least 25 healthy reference individuals evenly distributed for gender and age, and analysed 25 of the most commonly requested serum/plasma components from each reference individual. A reference material ( control) consisting of a fresh frozen liquid pool of serum with values traceable to reference methods

Pancreatic tissue grafting is by far the most physiological therapeutic solution to the insulin deficiency of diabetes. Recent clinical trials have indicated somewhat successful use of nonsteroidal immunosuppressive regimens and a successful nonhuman primate trial using CD154 for costimulation blockade was reported. However, these protocols need to be replaced with safe and efficacious ones in whi

Periconceptional use of folic acid is thought to reduce the risk for both neural tube defects and other congenital malformations. Most published data were obtained retrospectively. We used the Swedish Medical Birth Registry to study congenital malformations in infants born of women who reported the use of folic acid in early pregnancy (of which 70% probably used it also preconceptionally) and comp

Nigella damascena seeds were extracted by cold press, in a Soxhlet apparatus and with CO2 The yield obtained with liquid CO2 was only 10.57%. EtOH (1%) increased the yield by 50%. CO2-extracts were separated into the 2 fractions. The yield in the first fraction increased 2 times by increasing the pressure from 150 to 350 bar. EtOH (1%) increased the yield 2 times at 150 bar. Linoleic acid was the

In a 5-y retrospective follow-up study in southern Sweden that initially included > 1000 individuals with previously diagnosed erythema migrans, factors that influenced the risk of reinfection with Lyme borreliosis were elucidated. The total frequency of reinfection was 4% and the number of tick bites influenced the risk of reinfection: those bitten > 10 times during the observation period had a 4

Ribosomal protein S6 kinase (S6K) is activated by an array of mitogenic stimuli and is a key player in the regulation of cell growth. The activation process of S6 kinase involves a complex and sequential series of multiple Ser/Thr phosphorylations and is mainly mediated via phosphatidylinositol 3-kinase (PI3K)-3-phosphoinositide-dependent protein kinase-1 (PDK1) and mTor-dependent pathways. Upstre

Calponin (4.1-5.9 microM, pig stomach) inhibited maximal shortening velocity (Vmax) by 20-25% with only minor influence on force in skinned smooth muscle from guinea-pig taenia coli activated at different Ca2+ levels and with thiophosphorylation. Similar results were obtained with a fragment of the N-terminal 1-228 amino acids engineered using a mouse cDNA construct (5.4 microM). Both the native c

High spin states in the transitional nucleus Nb-87 up to 14 MeV excitation have been established for the first time via the reactions Ca-40(Cr-50, 3p)Nb-87 and Ni-58(S-32, 3p)Nb-87. The Nb-87 gamma-radiations have been identified through gamma-ray spectra taken in coincidence with the evaporation residues detected in the Daresbury recoil separator or with multiple proton emission. Gamma-gamma coin

Traditionally, human embryonic stem cells (hESCs) are propagated by mechanical dissection or enzymatic dissociation into clusters of cells. To facilitate up-scaling and the use of hESC in various experimental manipulations, such as fluorescence-activated cell sorting, electroporation, and clonal selection, it is important to develop new, stable culture systems based on single-cell enzymatic propag

AIMS: Although the perpetuation of several supraventricular arrhythmias is critically dependent upon intra-atrial conduction, the literature lacks detailed information on normal values of conduction velocity and degree of anisotropy. In order to explore these factors further, we have measured conduction velocities at the right atrial free wall during sinus rhythm and during atrial pacing in four d

The calpain-10 gene (CAPN10) has been associated with type 2 diabetes, but information on molecular and physiological mechanisms explaining this association is limited. Here we addressed this question by studying the role of CAPN10 for phenotypes associated with type 2 diabetes and free fatty acid (FFA) metabolism. Among 395 type 2 diabetic patients and 298 nondiabetic control subjects from Finlan

Popular Abstract in Swedish Matematiska modeller och simulering är viktiga verktyg för att hantera tekniska system. Trenden idag är att öka komplexiteten i system genom integrerad produktion och processoptimering. Att hantera dessa komplexa system kräver kunskaper inom många områden samtidigt. Modellbibliotek är ett bra sätt att paketera kunskap. Kommersiella simuleringsprogram tillandahåller bra This thesis describes basic models for thermo-fluid systems and the implementation of the models using a flexible object-oriented structure in the ThermoFluid library. Model libraries provide an excellent way to package engineering knowledge of systems to be reused by non-experts. Many commercial simulation packages provide good model libraries, but they are usually domain specific and closed. Mod

Vascular smooth muscle cell migration, occurring after intimal injury, is a substantial clinical problem in atherosclerosis and restenosis after stenting. Here we investigate the effects of polyamine synthesis inhibition on vascular smooth muscle cell migration after maximal and submaximal growth stimulation with PDGF-AB or FCS. Vascular smooth muscle cells were obtained from mouse aorta explants.
