Lacunar infarcts, small deep infarcts resulting from occlusion of a penetrating artery, account for about a quarter of all ischemic strokes. The view of lacunar infarcts as a benign and rather innocent vascular lesion has been modified during the last years. Although the prognosis is more favourable than other subtypes during the first years, probably due to the small lesion size, in a longer pers

Quenching of photoluminescence in a substituted polythiophene in the presence of a deposited C-60 layer is studied by steady-state and time-resolved photoluminescence (PL). The steady-state PL is evaluated by con -sidering the interference of the absorbed and emitted electro-optical field in the thin film coupled to exciton diffusion in the conjugated polymer. PL quenching occurs for excitons gene

The diffusion of glucose in a cubic lipid-water phase was studied with holographic laser interferometry. The X-ray diffraction data showed that the structure of the cubic phase could be described as a primitive cubic lattice under the experimental conditions used. The present study shows that holographic laser interferometry is suitable for determining the concentration profile due to diffusion, e
OBJECTIVE: To determine the natural history of adnexal cysts incidentally detected at transvaginal ultrasound examination and judged to be benign in postmenopausal women.METHODS: One hundred and thirty-four postmenopausal women referred for ultrasound examination and found to have an adnexal cyst judged to be benign and not causing any symptoms were followed with transvaginal ultrasound at 3, 6 an
A poly(Toluidine Blue O) (poly-TBO) modified electrode was successfully prepared by repeated sweeping the applied potential from -0.6 to + 0.8 V (vs. SCE) on a glassy carbon electrode (GCE) in borate buffer solution at pH 9.1 containing 0.1 M NaNO3 and 0.4 mM Toluidine Blue 0 (TBO). The poly-TBO modified GCE shows electrocatalytic activity toward NADH oxidation in phosphate buffer solution at pH 7
Relative autonomy refers to the space that teachers have or can create to make choices regarding the curriculum of schooling. In order to transform conflicts and to cope with the tensions that arise in time of change, teachers are urged to make constructive use of their relative autonomy. In this paper some of the conflicts and tensions that exist today are discussed in the context of the Swedish
Abstract in UndeterminedHistorically, the function of Arctic ecosystems in terms of cycles of nutrients and carbon has led to low levels of primary production and exchanges of energy, water and greenhouse gases have led to low local and regional cooling. Sequestration of carbon from atmospheric CO2, in extensive, cold organic soils and the high albedo from low, snow-covered vegetation have had imp
Huntington's disease (HD) is caused by a polyglutamine expansion in the protein huntingtin and is characterized by intraneuronal inclusions and widespread neuronal death at the late stage of the disease. In research, most of the emphasis has been on understanding the cell death and its mechanisms. Until recently, it was believed that the vast majority, if not all, of the symptoms in HD are a direc

We evaluated whether urinary excretion of the carboxy terminal domain (NC1) of Type IV collagen is associated with glomerular filtration rate and kidney size in Type I (insulin-dependent) diabetes mellitus (IDDM). Urinary excretion rate of NC1, glomerular filtration rate (GFR), and kidney size were measured in 16 men with Type I diabetes. Their mean age was 33.3 +/- 6.1 years with a duration of di
We have prepared a new type of anion exchanger, which effectively discriminates between RNA and plasmid DNA. The material is based on a Sephacryl S-500 HR matrix provided with quartenary amine anion-exchange groups. A distinguishing feature of the beads is that a thin (2-3 mum) outer layer of the beads lacks ion-exchange groups. In the synthesis of these beads the vinyl groups in the outer layer o
