BACKGROUND: Singletons born after IVF have an adverse perinatal outcome when compared with singletons in the general population. This study investigates maternal characteristics and IVF-treatment-related variables, for a possible influence on obstetric outcomes. METHODS: Data from all IVF clinics in Sweden, including all IVF singletons born after fresh treatment cycles and own oocytes during 2002-
Whether the safest roundabout design for cyclists is to separate cycle crossings or integrate cyclists with motorists is an extensively discussed issue. Studies using accident statistics indicate that a separated cycle crossing is the safest for high motor vehicle volumes. However, the results have not been satisfyingly explained. This article combines quantitative and qualitative methods in traff
This study examines possible success factors when developing technical solutions for dyslexic students. Findings in the literature, in a web survey answered by students and in the experiences from the development process at the Medical Faculty Library, Lund University, were used to find out potential success factors and difficulties. The literature found describes what dyslexia is, the situation f
Primary open angle glaucoma (POAG) is a major blindness-causing disease, characterized by elevated intraocular pressure due to an insufficient outflow of aqueous humor. The trabecular meshwork (TM) lining the aqueous outflow pathway modulates the aqueous outflow facility. TM cell adhesion, cell-matrix interactions, and factors that influence Rho signaling in TM cells are thought to play a pivotal
Background: Prior studies have identified some risk factors for stress fracture in athletes and military recruits. Objective: To determine whether historical factors, physical measures, biochemical variables of skeletal metabolism, genetic factors, bone density (BMD) and bone size could predict risk of stress fracture over 4 years in physically fit cadets at the US Military Academy (USMA). Methods
We investigate theoretically charge transport in hybrid multiterminal junctions with superconducting leads kept at different voltages. It is found that multiple Andreev reflections involving several superconducting leads give rise to rich subharmonic gap structures in the current-voltage characteristics. The structures are evidenced numerically in junctions in the incoherent regime.
It has been difficult to establish whether we are limited to the heart muscle cells we are born with or if cardiomyocytes are generated also later in life. We have taken advantage of the integration of carbon-14, generated by nuclear bomb tests during the Cold War, into DNA to establish the age of cardiomyocytes in humans. We report that cardiomyocytes renew, with a gradual decrease from 1% turnin
This study explores factors associated with the individual's appraisal of anticipated environmental changes caused by energy production facilities. The study took place in a Swedish village where exploratory drilling, that could eventually lead to a uranium mine, was being conducted at the same time as a wind farm was approved. Results from the survey, which included the total population, were int
The intensity of a fire is an important factor determining the recovery of soil microorganisms after a forest fire, since it can alter the quality and quantity of carbon sources. Recovery of the microbial community was studied in a Mediterranean pine forest soil subjected to different temperatures to simulate the short-term effects of fire intensity on bacterial and fungal growth, estimated using
Background: Different molecular subtypes of breast cancer have been identified based on gene expression profiling. Treatment suggestions based on an approximation of these subtypes by immunohistochemical criteria have been published by the St Gallen international expert consensus panel. Ductal carcinoma in situ (DCIS) can be classified into the same molecular subtypes. Our aim was to study the rel
Genome-wide association studies have recently identified at least 15 susceptibility loci for systemic lupus erythematosus (SLE). To confirm additional risk loci, we selected SNPs from 2,466 regions that showed nominal evidence of association to SLE (P < 0.05) in a genome-wide study and genotyped them in an independent sample of 1,963 cases and 4,329 controls. This replication effort identified fiv
Use of utilities, such as steam and cooling water, is very common at industrial sites. Utilities are often shared between several production areas, and a disturbance in the supply of a utility is therefore likely to affect a large part of the production site, and cause great loss of revenue. In order to minimize the loss of revenue due to disturbances in utilities, the optimal supply of utilities
Popular Abstract in Swedish Belysning står för en femtedel av den globala elanvändningen. I Sverige motsvarar efterfrågan på energi för belysning i kontorsbyggnader 20% av den totala elanvändningen. Utbyte av gamla belysningsanläggningar anses vara bland de mest kostnadseffektiva sätten att minska energianvändningen i byggnader. I synnerhet utlovar användningen av avancerade ljusstyrningssystem enLighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. In particular, the use of advanced lighting control systems promises energy savings of between 2 and 60%, but system
The accuracy, precision and limitations of the imaging technique named Structured Laser Illumination Planar Imaging (SLIPI) have been investigated. SLIPI, which allows multiply scattered light to be diminished, has previously demonstrated improvements in image quality and contrast for spray imaging. In the current study the method is applied to a controlled confined environment consisting of a mix
Despite various criticisms, Ian Barbour's fourfold classification of the possible relationships between religion and science remains influential. I compare Barbour's taxonomy with the theories of four authors who, in the last four decades, have addressed the relationship between science and religion from a Muslim perspective. The aim of my analysis is twofold. First, I offer a comparative perspect
Based on an empirical analysis of a yearlong netnography of a Swedish online fashion community, and the explication of the concept of modern cynicism, this paper develops a novel perspective on consumer morality. The analysis suggests that modern cynicism informs consumers of the reasonableness in consciously stating one type of morality while acting out another, in order to handle the morally con
A new approach for photoelectrocatalytic oxidation of NADH is described, based on a graphite electrode (G) modified with a new phenothiazine derivative, polyphenothiazine formaldehyde (PPF). Electrochemical measurements reveal that G/PPF presents a quasireversible voltammetric response, corresponding to a 2e(-)/2H(+) transfer and that G/PPF modified electrodes show electrocatalytic activity for NA
