Molecular analysis of the O alleles at the blood group ABO locus in populations of different ethnic origin reveals novel crossing-over events and point mutations

The blood group ABO genotypes of 138 group O individuals with three different ethnic origins in Brazil were determined, including Whites, Blacks and Amerindians. Several previously undescribed O alleles were found, predominantly in the Black group, in which about a third of the samples did not conform to previously known O allele structures. It has been well documented for the first time that some

Tunneling spectroscopy of a quantum dot through a single impurity

A single impurity inside a resonant tunneling diode is used to perform tunneling spectroscopy on an adjacent electrostatically defined vertical quantum dot. This results in tunneling between two zero-dimensional systems, measured as a set of sharp peaks in the current-voltage spectrum for finite bias. Magnetic-field-dependent measurements show that the angular momentum of the tunneling electrons i

Crystallographic characterization of two novel crystal forms of human insulin induced by chaotropic agents and a shift in pH

Background: Insulin is a therapeutic protein that is widely used for the treatment of diabetes. Its biological function was discovered more than 80 years ago and it has since then been characterized extensively. Crystallization of the insulin molecule has always been a key activity since the protein is often administered by subcutaneous injections of crystalline insulin formulations. Over the year

Incidence of hand eczema in female Swedish hairdressers

Objective: To estimate the occurrence of hand eczema in hairdressers in Sweden. Methods: The occurrence of hand eczema was estimated in a Swedish longitudinal retrospective cohort study including all female graduates from vocational schools for hairdressers from 1970 to 1995. A stratified sample from the general population acted as controls. A self-administered questionnaire including questions on

Wave-propagation from medical implants -influence of body shape on radiation pattern

The influence of a patient's body shape and position on the radiation pattern from an implanted radio transmitter has been simulated. Simulations and comparisons have been made with different body shapes (male, female and child) and different arm positions. It can be concluded from the results that the difference between different body shapes are at least as large as the influence of a patients ar

Resonant soft X-ray emission spectroscopy of doped and undoped vanadium oxides

Resonant soft X-ray emission (RSXE) spectra of NaV2O5, MoxV1-xO2 and V2O3 have been recorded for a series of excitation energies at resonances of the V L- and O K-absorption band. Resonant excitation allows us, firstly, to separate V 3d and O 2p projected density-of-states of the valence band and, secondly, to study charge-neutral low-energy excitations due to resonant inelastic X-ray scattering (

Reduced level of serum thiols in patients with a diagnosis of active disease

Oxidative stress, or the production of oxygen-centered free radicals, has been hypothesized as the major source of DNA damage that in turn can lead to altered genetic expression, disease, and aging of humans. Serum protein thiol levels in blood are a direct measure of the in vivo reduction/oxidation (redox) status in humans, because thiols react readily with oxygen-containing free radicals to form

Teambaserad rehabilitering – bäst för motiverad patient.

Motivationen har stor betydelse för att rehabilitering ska ge ett gott resultat, det har studerats och förts till bevis i andra studier. Den första långtidsuppföljningen av motivationens betydelse ur ett hälsoekonomiskt perspektiv vid rehabilitering har genomförts i Kronobergs län.

Making Manufacturing Flexibility Operational Part 2 - Distinctions and an Example

Structures the concept of flexibility by making clear distinctions in three generic dimensions, describes the use of the framework for manufacturing flexibility by working through a concrete example. The framework was presented in “Making manufacturing flexibility operational – part 1: a framework”, IMS, Vol. 6 No. 2. Makes distinctions between the concept of flexibility in the three generic dimen

Vesicular-arbuscular mycorrizae for dating multiple paleosols and carbon loss rate determination

A promising technique for dating paleosols is reported based on radiocarbon (C-14) dating of asexual spores from vesicular-arbuscular mycorrizae (VAM). The soils are dispersed in water and some 6000-8000 spores separated by hand picking under a low power microscope. The dried spores are then dated by accelerator mass spectroscopy (AMS). A chronosequense of closely superimposed paleosols from an ar

Boringholm- en östjysk traeborg

The book is a monographie about a wooden castle in east Jutland in Denmark. The castle existed in the 14:th cent and all kind of archaeological material is extremely well preserved. The excavation took place in 1905 and was made by the famos danish archeologist C.M. Smidt and his assistent Christian Axel Jensen. The work was finished in 1916 but first now after 90 years the report was written

Cholesterol depletion impairs vascular reactivity to endothelin-1 by reducing store-operated Ca2+ entry dependent on TRPC1.

The reactivity of the vascular wall to endothelin-1 (ET-1) is influenced by cholesterol, which is of possible importance for the progression of atherosclerosis. To elucidate signaling steps affected, the cholesterol acceptor methyl-ß-cyclodextrin (mßcd, 10 mmol/L) was used to manipulate membrane cholesterol and disrupt caveolae in intact rat arteries. In endothelium-denuded caudal artery, contract
