- Type 2 or non-insulin-dependent diabetes mellitus (NIDDM) is the most common form of diabetes worldwide, affecting approximately 4% of the world's adult population. It is multifactorial in origin with both genetic and environmental factors contributing to its development. A genome-wide screen for type 2 diabetes genes carried out in Mexican Americans localized a susceptibility gene, designated NIDDM1, to chromosome 2. Here we describe the positional cloning of a gene located in the NIDDM1 region that shows association with type 2 diabetes in Mexican Americans and a Northern European population from the Botnia region of Finland. This putative diabetes-susceptibility gene encodes a ubiquitously expressed member of the calpain-like cysteine protease family, calpain-10 (CAPN10). This finding suggests a novel pathway that may contribute to the development of type 2 diabetes.

- We have performed x-ray magnetic circular dichroism, x-ray resonant magnetic scattering and scanning tunnelling microscopy measurements on ultrathin Co films deposited on flat and vicinal Cu(111). The range of film thickness varies between one and 25 monolayers. For the vicinal Cu(111), Co deposition below one monolayer leads to the formation of elongated islands preferentially oriented along the step edges. These islands extend over lateral length scales of up to several thousand angstroms. For the thicker films we still observe that the vicinal surface leads to the occurrence of a preferential uniaxial growth direction. No such preferential growth direction can be identified for the flat surface. In correlation to the Co growth we observe an increase of both the orbital and the spin moment per Co atom on vicinal Cu(111) of about 25% versus what was observed for Co on flat Cu(111). This enhancement is observed in both the x-ray absorption and the reflectivity measurements. Similar to what was earlier reported for Co on Cu(100) we also observe for the case Co on Cu(111) an increase in the ratio m(l)/m(s), (orbital to spin moments) of 40% for thin Co films. In contrast to what has been reported for Co films on flat and vicinal Cu(100) we do not observe any major variations in the occupancy of the Co 3d states for Co grown on the vicinal Cu(111) surface.

- The aim of the present study was to identify in a standardized experimental rat liver tumor system the drugs which are most appropriate in influencing the relationship between liver tumor and normal liver parenchyma blood flow as estimated with 133Xe washout clearance method, and thereby positively influencing the kinetics of chemotherapeutic drugs. A battery of vasoactive drugs, which according to a literature review were considered to be active, were tested.

Pathway of the shear-induced transition between planar lamellae and multilamellar vesicles as studied by time-resolved scattering techniques
- 2003

Tidskriftsartikel (refereegranskat)abstract
- We report on the shear-induced transition from an oriented lamellar phase (L, phase) to multilamellar vesicles (MLV) in two nonionic surfactant systems, namely, a 40 wt % sample of triethylene glycol monodecyl ether (C10E3) and a 40 wt % sample of tetraethylene glycol monododecyl ether (C12E4) in D2O. This transition was studied by time-resolved small-angle neutron and light scattering under shear. Within a range of shear rates from 2 to 100 s(-1) at 25 degreesC the transition from the L-alpha, phase to MLVs in the C10E3 system apparently is controlled by strai . This transition involves an intermediate structure with cylindrical scattering symmetry. This can be interpreted as multilamellar cylinders (MLCs) or as a coherent stripe buckling with the wave vector of the undulation in a neutral direction. The intermediate structures found along the transition path are stable for long times, when shear is turned off. This allows for studies on trapped intermediate structures and experiments where different positions within the gap of a couette shear cell were examined in so-called gap-scan experiments. These experiments revealed that the transition from planar lainellae to MLVs is homogeneous throughout the gap. A temperature increase to 32 degreesC changes neither the pathway nor the strain control in comparison with experiments run at 25 degreesC. Upon a further increase in temperature to 38 degreesC, the transition leads to a mixture of MLC and planar lamellae or a weakly buckled state. With C12E4 as surfactant, and therefore with changed bilayer properties, a strai control is still observed, but less strain is needed for the transition compared to that of the C10E3 system. A comparison of the transition for the two systems, their transient as well as their steady-state viscosities, indicates that the transition is controlled by the stress.
