Retinitis Pigmentosa (RP) is a group of uncured retinal diseases with the world wide incidence of about 1/3500. In spite of the huge efforts in past years, the mechanisms underlying this type of hereditary blindness has not been elucidated and nor any effective treatment available. The rd1 mouse strain carries a mutation in ?-subunit of phosphodiesterase gene which hydrolyzes the cGMP and is need

We compare magnetism in two artificial lattice structures, a quantum dot array formed in a two-dimensional electron gas and an optical lattice loaded with repulsive, contact-interacting fermionic atoms. When the tunneling between the lattice sites is strong, both lattices are non-magnetic. With reduced tunneling in the tight-binding limit, the shell-filling of the single-site quantum wells combine

This article deals with the question of heteronormativity, or more precisely, how heteronormativity pertains to the reception of the Swedish film by Lukas Moodysson, Show Me Love (Fucking Åmål).

Digital systems are integrated in our environment and have become a natural part of our every day life. As we rely more on these systems our expectations on them increases. We expect them to perform new tasks, communicate and cooperate. The complexity of these systems are increasing. The increasing complexity and the requirement for flexibility, which allows the system to adapt and evolve over tim

The reduced form of vitamin C, ascorbic acid, is well known for its function as an antioxidant and as a protective agent against scurvy. However, many recent studies indicate other functions for vitamin C in mammalian cells. Novel findings provide possible explanations for observed beneficial effects of a high intake of vitamin C on cell growth, gene transcription, host resistance to infection, up

Recognition is a concept with long standing in discourses on diplomacy, international relations, and international law. Recognition is a prerequisite for reciprocal exchanges in international relations. The principles of diplomatic recognition have, however, varied considerably throughout history, between the two poles highly inclusive and highly exclusive. Paradoxically, the European Union figure

A new method for the preparation of benzo[b]indolizidines and benzo[b]quinolizidines based on two reactions: an amine induced ring-opening of 3-bromo-2,5-dimethylthiophene-1,1-dioxide (1) with 2-allyl-pyrrolidine (2), 2-allylpiperidine (3), 2-[2-(1',3'-dithiolan)methyl]pyrrolidine (4) and 2-[2-(1'-3'-dithiolan)methyl]piperidine (5); and an intramolecular Diels-Alder reaction, is described. Copyrig

OBJECTIVES: To evaluate if patients with acute lacunar syndromes have acute lacunar infarcts or other types of cerebral lesions on diffusion-weighted MRI. METHODS: Patients with acute lacunar syndromes underwent echo-planar diffusion MRI of the brain within 3 days after stroke onset. Localization and size of lesions with hyperintense signal were determined, compared with clinical characteristics a

A search for gravitinos produced in e(+/-)p collisions is performed using the H1 detector at HERA. The data were taken at a centre-of-mass energy of 319 GeV and correspond to an integrated luminosity of 64.3 pb(-1) for e(+)p collisions and 13.5 pb(-1) for e(-)p collisions. If R-parity is not conserved, the t-channel exchange of a selectron can produce a neutralino, which, in models where the gravi

Aim: To value the importance of research on avian migration for the development and current status of Spanish ornithology. Results and Conclusions: Avian migration has always been an outstanding field in ornithology. This assertion is particularly true in Spain, as we illustrate here by discussing the contribution of migration research to both the scientific and historical development of Spanish o

Five molybdenum oxide samples, subjected to conditions of oxidative ammonolysis and ammoxidation of toluene at 450 and 460°C, respectively, have been characterized using X-ray diffraction, scanning and transmission electron microscopy, and specific surface area measurements. In oxidative ammonolysis, the relatively large, freshly prepared MoO3 crystals are reduced to smaller MoO2 crystals with a c

The level of variation and the mutation rate were investigated in an empirical study of 244 chloroplast microsatellites in 15 accessions of Arabidopsis thaliana. In contrast to SNP variation, microsatellite variation in the chloroplast was found to be common, although less common than microsatellite variation in the nucleus. No microsatellite variation was found in coding regions of the chloroplas

The aims of this study were to investigate whether hypertrophy of the small intestinal smooth muscle leads to alterations of myosin isoform composition and shortening velocity and whether possible changes correlate with a change in the sensitivity to ADP of shortening velocity in this tissue. A partial occlusion was introduced in the distal part of the ileum of guinea-pigs. After 2 weeks, the part

OBJECTIVE. The goal was to examine whether being a victim of bullying was associated with medicine use, taking into account the increased prevalence of physical and psychological symptoms. METHODS. The study population included all students in grades 5, 7, and 9 (mean ages: 11.6, 13.6, and 15.6 years, respectively) in a random sample of schools in Denmark (participation rate: 88.5%; N = 5205). The

Twenty chambers for measurement of soil CO2 efflux were compared against known CO2 fluxes ranging from 0.32 to 10.01 mumol CO2 m(-2) s(-1) and generated by a specially developed calibration tank. Chambers were tested on fine and coarse homogeneous quartz sand with particle sizes of 0.05-0.2 and 0.6 mm, respectively. The effect of soil moisture on chamber measurements was tested by wetting the fine

Objective: To describe and compare the consumption of the main groups and subgroups of vegetables and fruits (V&F) in men and women from the centres participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). Design: Cross-sectional analysis. Dietary intake was assessed by means of a 24-hour dietary recall using computerised interview software and standardised pro

Relationships between demographic-, treatment-, and sickness-related factors, metabolic control (HbA1c), perceived burden of illness, and degree of depressive symptoms were examined in a group of 155 insulin-dependent diabetic patients, aged 35.3 +/- 8.9 years. The patients completed a questionnaire measuring depressive symptoms and three aspects of perceived burden of illness. No gender differenc
