Background. Urban birth, a risk factor for schizophrenia, is more frequent among secondgeneration immigrants. The aim of the current study was to determine whether the increased risk for schizophrenia found in second-generation immigrants is explained by the degree of urbanization of birthplace and/or factors related to parentage, such as geographic origin or history of residence abroad during upb

Desert locusts are guided by olfactory cues in different behavioural contexts. In order to understand the basis for the variable olfactory guided behaviour displayed by different developmental stages and by solitary and gregarious locusts, we investigated their central olfactory system with neuroanatomical and neurophysiological methods. The primary olfactory centre of the brain, the antennal lobe

A method has been developed for establishing a "University Without Walls" for the purpose of studying the relationship between electrocardiographic estimation and magnetic resonance imaging measurements of myocardial infarct size. The research team includes faculty and students from 4 medical centers, with expertise extending from clinical to technical. Weekly interactive videoconferences provide

Background: Social interaction is crucial for whether a person will successfully accomplish important life tasks. Aim and method: This study investigated the importance of sociodemographic, clinical and self-perceived health-related factors for social interaction among 103 individuals with persistent mental illness, mainly psychoses, visiting an outpatient unit. Results: Bivariate analyses pointed

The possibility and biological effects of substituting silicon in a-tricalcium phosphate (alpha-TCP) by way of solid-state reaction have been evaluated. a-TCP powders with varying substitution amounts (1 and 5 mol % Ca2SiO4) were synthesized by reacting mixtures of CaCO3, Ca(2)P(2)O7, and SiO2, at a rate of 4 degrees C(min)(-1) to 1100 degrees C, left to dwell for 2 h and then heated to 1325 degre

In this article we present a spatio-temporal dynamic model that can be realized using image warping. Image warping is a non-linear deformation which maps every point in one image plane to a point in another image plane. Using thin-plate splines, these deformations are defined by how a small set of points is mapped, making the method computationally tractable. In our case the dynamics of the proces

Aspects of parental interaction were assessed in 20 families with diabetic, insulin-dependent children, using hour-long video-taped interviews, the children being in optimal (O, n = 10) or poor (P, n = 10) metabolic control and showing optimal or poor psychological adaptation. In comparison with the O-group parents, the P-group parents were less appreciative of one another, were less congruent in

Sera from 79 patients with acute self-limiting hepatitis, 17 patients with acute hepatitis B evolving into chronic HBsAg carriership, and 43 chronic HBsAg carriers without a history of acute hepatitis were analyzed for presence of hepatitis B virus (HBV)-DNA by a molecular hybridization technique. In acute self-limiting hepatitis, HBV-DNA was cleared within a few weeks after the onset of clinical

The aim of this study was to explore possible regional differences in the use of coercion in psychiatric care as experienced by patients and relatives. At four psychiatric care settings in different parts of Sweden, 138 committed and 144 voluntarily admitted patients were interviewed at admission using the Nordic Admission Interview. At discharge or, if the care episode was still ongoing, after 3

When a child is hospitalized, the parents find themselves in an unfamiliar environment and their parental role changes. They are in a stressful and often anxiety-filled situation and it may be difficult for them to participate in decisions. The purpose of this study was to examine the extent to which parents participate in decisions during the course of events when their child is hospitalized. Thi

In situ postgrowth annealing of (Ga,Mn)As layers under As capping is adequate for achieving high Curie temperatures (T-C) in a similar way as ex situ annealing in air or in N-2 atmosphere practiced earlier. Thus, the first efforts give an increase of T-C from 68 to 145 K after 2 h annealing at 180 degrees C. These data, in combination with lattice parameter determinations and photoemission results

Podophyllotoxin (CPH86), at concentrations of 5 ng/ml or more, inhibited [3H]-thymidine uptake of ConA-induced proliferation of human peripheral mononuclear blood cells. Tween80, the detergent included in the anti-inflammatory drug Proresid, containing podophyllum lignan derivatives, also inhibited lymphocyte proliferation in a dose-dependent manner. Combination of the two drugs did not, or did on

Disorders of the vestibular nerve and end organs are the most common causes of vertigo. The advances in recognizing different forms of canalolithiasis and cupulolithiasis, which sometimes present with continuous positional nystagmus, have revealed a peripheral vestibular aetiology in which central nervous system lesions were previously suspected. Treatments using repositioning manoeuvres are also

Good genes" are genetic elements that contribute to lifetime reproductive success, regardless of an individual's additional genotype. Their existence is debated, and most work has targeted their viability benefits to the offspring of choosy females. In the present study, we analyze a case of potential good genes effects in adult male sand lizards ( Lacerta agilis). We show that males with a partic

Large eddy simulations (LES) are performed for single and multiphase jets in crossflow (JICF). The multiphase JICF are compared to the single-phase case for the same momentum and mass flow, ratios but with droplets of different sizes. Multiphase JICF have stronger counterrotating vortex pairs (CVPs) than a corresponding single-phase JICF. Moreover their trajectories are higher and their induced wa
