BACKGROUND: The possible excess of congenital malformations in infants born after in vitro fertilization (IVF) has been much discussed in the literature, with controversial conclusions. This population based study is aimed at analyzing the presence of congenital malformations in a large group of infants born after IVF and to compare malformation risk both with that of all infants born and accordin

BACKGROUND: Central venous oxygen saturation (ScvO2) and oxygen tension (PcvO2), obtained from the superior vena cava, correlate well with mixed venous (pulmonary arterial) oxygen saturation (SvO2) and tension (pvO2) when the hematocrit is normal. The present study was undertaken to assess whether extreme hemodilution affects this relation. METHODS: We compared mixed and central venous blood durin

The 7-10 November 2004 period contains two events for which the local ground magnetic field was severely disturbed and simultaneously, the solar wind displayed several shocks and negative B-z periods. Using empirical models the 10-min RMS Delta X and Delta Y at Brorfelde (BFE, 11.67 degrees E, 55.63 degrees N), Denmark, are predicted. The models are recurrent neural networks with 10-min solar wind

The paper focuses on the changing economic geographies of the outer city of Copenhagen. The outer city is not a well-defined place but can be understood as a set of processes transforming the urban economic landscape outside the built- up area. Several central and interrelated economic processes transform the outer city. The paper examines the changing industrial dynamics and location spaces withi

The classic kinetic model for cellulose hydrolysis is often referred to as pseudo-homogeneous, a term revealing the insight that the process is actually heterogeneous. During the past 10-15 yr, the shortcomings of this model have been demonstrated in various studies and the interest in the heterogeneous aspects has increased. The present work presents a simplistic model in which the intrinsic, het

In several cases, inorganic salts have been used to induce partly structured states in protein folding. But what is the nature of these states: Do they represent key stepping stones in the folding process, or are they circumstantial pitfalls in the energy landscape? Here we report that, in the case of the two-state protein S6, the salt-induced collapsed state is off the usual folding routes in the

Effective treatment of haemophilic arthropathy requires a detailed evaluation of joint integrity. Methodological assessment of magnetic resonance imaging (MRI) scores are needed to assure reproducibility of measurements when comparing results of clinical trials conducted in different centres. We compared the reliability of two MRI scoring systems for assessment of haemophilic arthropathy: one prog

The strength and range of surface forces in a system consisting of charged polymers with variable intramolecular stiffness confined between two charged planar surfaces have been investigated by Monte Carlo simulations. The negatively charged surfaces are neutralized by polymers carrying charges of opposite sign. Introducing the intermediate intrinsic stiffness of the chains gives rise to a weaker,

The overall aim of the present study was to assess in greater detail the sustained effects of a broad-based cognitive training programme on the neuropsychological performance of children with acquired brain injury. In particular, the long term (6 months) effects on cognitive functions, as well as how various moderators (gender, age at the time of injury/diagnosis, time since injury/diagnosis, age

The human L3MBTL gene is located in 20q12, a region that is commonly deleted in myeloproliferative disorders (MPD), myelodysplastic syndromes (MDS), and acute myeloid leukemia (AML). L3MBTL is highly homologous to the D-lethal(3) malignant brain tumor [D-l(3)mbt] gene, which is a putative tumor-suppressor gene (TSG) identified in Drosophila and which is closely related to the Drosophila sex combs

Studies of how organisms are adapted to regional climatic conditions are valuable when predicting the effects of global climatic changes on biota. Here we report on the geographical variation in timing of breeding and moult of an Arctic breeding wader, the dunlin (Calidris alpina). The Palearctic study sites range latitudinally between 68 and 76 degreesN and longitudinally between 46 and 179 degre

Individuals (n = 18) in remission from acute leukemia or highly malignant lymphoma were asked to narrate their lived experience of falling ill, of being under treatment, and life following this event. The transcribed texts were analyzed from a phenomenological-hermeneutic perspective, expanded by their medical and social history as related in interviews. The analysis revealed 3 themes: (I) Believe

A procedure for obtaining quantitative wave and morphodynamic data in a laboratory setting using video images has been developed. The steps include image capture, rectification, and data extraction. All the necessary steps were maintained within the MATLAB environment so the process was streamlined and large amounts of data processed. The procedure involves the use of a program to rectify images,

In this paper we study the adsorption at cationic emulsion droplets of starch which had been hydrophobically modified with octenyl succinic anhydride (OSA), a modification which also renders the starch anionic. Emulsions were formed with didodecyldimethylammonium bromide (DDAB) after which the OSA-starch was added. The emulsions were separated by centrifugation and the surface load of OSA-starch w

Neurofibroma is a benign tumor originating from Schwann cells in peripheral nerve sheaths and may occur as a sporadic tumor or as part of the dominantly inherited tumor syndrome NF1. NF1 is caused by constitutional mutations in the NF1 gene, located in chromosome band 17q11 Whereas the involvement of the NF1 gene in neurofibroma development in NF1 patients has been fairly well characterized, the s

This article is based on an interview study of how ten young male crime victims talk about violent events and actors involved. It focuses on how the young men present their identities as ‘young men’ who have been victims of violent crimes. In their narrations the men struggle with a cultural understanding that ‘masculinity’ is associated with strength and power, while ‘victim’ is associated with w

Sediment sequences retrieved from Lake Medvedevskoye (60degrees13'N 29degrees54'E) and Lake Pastorskoye (60degrees13'N, 30degrees02'E). Karelian Isthmus, northwestern Russia, were analysed for lithology, pollen and diatom stratigraphy, total organic carbon content and mineral magnetic parameters. Age control for both sequences was provided by AMS C-14 measurements and the Vedde Ash tephra. The rec
