Objective To evaluate whether N-acetyleysteine (NAC) infusion during the first week of life reduces the risk of death or bronchopulmonary dysplasia (BPD in infants with extremely low birth weight. Study design In a Nordic multicenter, double-blind trial, infants (n = 391) weighing 500 to 999 g and on ventilator or nasal continuous positive airway pressure were randomized before the age of 36 hours

BACKGROUND: Although the true benefits and disadvantages of prostate cancer screening are still not known, the analysis of fatal cases is important for increasing knowledge of the effects of prostate cancer screening on mortality. Who dies from prostate cancer despite participation in a population-based prostate-specific antigen (PSA) screening program? METHODS: From the Goteborg branch of the Eur

In previous work we have demonstrated increased expression of NOX2 in cardiomyocytes of infarcted human hearts. In the present manuscript we investigated the functional role of NOX2 in ischemically challenged H9c2 cells, a rat cardiomyoblast cell line, and adult rat cardiomyocytes. Expression of NOX2 in H9c2 cells was confirmed by RT-PCR. In Western-blot experiments, increased NOX2 expression was

It has been shown that the gene ERG in 21q22 is rearranged in the the t(16;21)(p11;q22) associated with acute myeloid leukemia (AML). ERG is a member of the ETS gene family and is fused with EWS in a subset of Ewing's sarcomas. EWS in 22q12 has a very high homology with FUS (also called TLS) in 16p11; the latter gene is rearranged in the t(12;16)(q13;p11) that characterizes myxoid liposarcoma. To

The aim was to investigate patients and therapists perception of receiving and giving dialectical behavioral therapy (DBT). Ten deliberate self-harm patients with borderline personality disorder and four DBT-therapists were interviewed. The interviews were analyzed with qualitative content analysis. The patients unanimously regard the DBT-therapy as life saving and something that has given them a

The objective of this article is to report and discuss the changing point prevalence rate of neurosis 1947-1997 in the Lundby cohort. The Lundby Study is a prospective longitudinal study of a geographically defined total population in the south of Sweden. Field investigations were performed in 1947, 1957, 1972 and in 1997, with psychiatrists interviewing the probands in a semi-structured way. Addi

A plane wave impinges on a perfectly conducting thick screen perforated with a periodic array of apertures with arbitrary cross-section. The transmission and reflection coefficients are determined by a mode matching technique, earlier used by other authors for the case where the apertures have the geometry of a classical waveguide. The fields outside the screen are expanded in Floquet modes, while

High-speed communication using the copper network, originally installed for telephony, is one of the dominant Internet access techniques. Several variants of a technology referred to as digital subscriber line (DSL) have been developed, standardized and installed during the last two decades. Essentially, DSL achieves high rates by exploiting wide bands of the copper cable channel. The shorter the

During glacial periods, dust deposition rates and inferred atmospheric concentrations were globally much higher than present. According to recent model results, the large enhancement of atmospheric dust content at the last glacial maximum (LGM) can be explained only if increases in the potential dust source areas are taken into account. Such increases are to be expected, due to effects of low prec

The PCR-mediated plasmid DNA deletion method is a simple approach to delete DNA sequences from plasmids using only one round of PCR, with two primers, and without ligation or purification prior to in vivo recombination. By using only PCR, the method is sequence independent and, as shown in this study, is applicable to various sizes of plasmids and deletions using minimal primer design.

The present study was designed to determine the interrelationships between sex, weaning age, and weaning weight on aspects of physiological and gastrointestinal development in pigs. Forty-eight Large White x Landrace pigs were used in a factorial arrangement with the respective factors being: age at weaning ( 14 or 28 days), weight at weaning ( heavy or light), sex ( boar or gilt), and time after

In this paper, a high-resolution finite volume method for calculating solutions to a hyperbolic conservation law is presented. The method works in two space dimensions on general domains and uses curvilinear meshes. A non-trivial estimation of gradients needed for the reconstructions is presented. The paper contains examples of numerical solutions of the Enter gas dynamics equations.

Aim. This paper reports a study investigating quality of life in relation to loneliness, caregiving, social network, gender, age and economic status among caregiving men and women in a population-based sample aged 75 years or older.Background. Because of demographic changes, in the future more care for older people will be given by informal caregivers who are themselves older. Being old and caring

To develop PDT beyond treatment of thin superficial tumours, to also be an efficient treatment alternative for deeply located and/or thick tumours, a system based on interstitial illumination using multiple fibres has been developed. Conditions that could benefit from such a treatment modality are for instance malignant brain tumours and tumours in the oral cavity. In interstitial PDT one needs to

Three intermediate to rhyolitic Icelandic Holocene tephra horizons (Hekla-3, Kebister, and Hekla-4) have been identified in annually laminated (varved) lake sediments in the Province of Varmland, west central Sweden. Calendar year ages were obtained from varve counts and are supported by additional C-14 dating based on terrestrial plant macrofossils. The varve ages of the three tephras are 3295 +/

InAs nanowire samples grown by metal-organic chemical vapor deposition present a significant amount of wurtzite structure, while the zincblende lattice is known to be the stable crystal structure for the bulk material. The question of the wurtzite distribution in the sample is addressed using phase-sensitive coherent X-ray diffraction with a micro-focused beam at a synchrotron source. The simultan
