Background: Previous studies indicate that there may be infant gender differences in cytokine expression associated with differences in neonatal morbidity. Objective: We tested the hypothesis that umbilical cord interleukin-1 receptor antagonist (IL-1ra) correlates with infant gender and neonatal outcome in preterm infants. Study Design: IL-1ra was measured in cord blood taken from 58 preterm infa

The spectrum of six times ionized sulphur, S VII, has been investigated in the wavelength region 200-4000 Angstrom by means of the beam-foil and laser-produced plasma techniques. The analysis comprises 219 lines of which 105 are newly identified. The present work establishes 123 2s(2)2p(5)nl energy levels of which 66 are new. The level energies are determined with an internal consistency of better

The aim was to test the hypothesis that the human leucocyte antigen (HLA) haplotype that is not inherited from the mother, that is, the non-inherited maternal antigen (NIMA) affects the risk for type 1 diabetes (T1D). A total of 563 children with T1D and 286 non-diabetic control children from Sweden were genotyped for DRB1, DQA1 and DQB1 alleles. The frequency of positively (DR4-DQA1*0301-B1*0302

The biochemical mechanisms that underlie hypoxia-induced NF-kappa B activity have remained largely undefined. Here, we find that prolonged hypoxia-induced NF-kappa B activation is restricted to cancer cell lines infected with high-risk human papillomavirus (HPV) serotypes. The HPV-encoded E6 protein is necessary and sufficient for prolonged hypoxia-induced NF-kappa B activation in these systems. T

Reception of partially correlated fields by two closely coupled electrical dipoles is discussed as a function of load impedances and open-circuit correlations. Two local maxima of the power may be achieved for two different load impedances, but in those cases the output correlations are high. Choosing the loads to give zero output correlations is possible for almost any real-valued open-circuit co

Reverse link capacity of a direct-sequence code-division multiple-access (DS-CDMA) system in a multicell environment has been studied recently, and significant capacity improvements due to the use of beamforming have been observed. However, system performance with beamforming will be affected by several impairments, such as direction of arrival estimation errors, array perturbations, mutual coupli

We have used time-resolved X-ray diffraction to monitor the resolidification process of molten InSb. Melting was induced by an ultra-short laser pulse and the measurement conducted in a high-repetition-rate multishot experiment. The method gives direct information about the nature of the transient regrowth and permanently damaged layers. It does not rely on models based on surface reflectivity or

Integrin alpha 10 beta 1 is a collagen-binding integrin expressed on chondrocytes. In order to unravel the role of the alpha 10 integrin during development, we generated mice carrying a constitutive deletion of the alpha 10 integrin gene. The mutant mice had a normal lifespan and were fertile but developed a growth retardation of the long bones. Analysis of the skeleton revealed defects in the gro

Objective: To investigate the relationship between memory and intensive care sedation. Design and setting: Prospective cohort study over 18 months in two general intensive care units (ICUs) in district university hospitals. Patients: 313 intubated mechanically ventilated adults admitted for more than 24 h, 250 of whom completed the study. Measurements: Patients (n = 250) were interviewed in the wa

The Gaussian wave model has been successfully used in ocean engineering for more than half a century. It is well understood, and there exists both exact theory and efficient numerical algorithms for calculation of the distribution of safety related wave characteristics, such as crest height and steepness. Its drawback is its lack of realism: it produces waves which are stochastically symmetric, bo

Children with specific language impairment (SLI) are often described as having great difficulty with grammatical morphology, but most studies have focused only on these childrens use of verb morphology. In this study, we examined the use of noun phrase (NP) morphology by preschool-age children with SLI who are acquiring Swedish. Relative to typically developing same-age peers and younger peers mat

Larsson PG, Bergstrom M. Forsum U, Jacobsson B, Strand A, Wolner-Hanssen P Bacterial vaginosis. Transmission, role in genital tract infection and pregnancy outcome: an enigma. APMIS 2005; 113:233-45. Whether bacterial vaginosis (BV) is acquired from an endogenous or an exogenous source is subject to controversy Despite findings of an association between sexual behaviour and BV some data indicate t

We present results on the measurement of Lambda and (&ULambda;) over bar production in Au+Au collisions at roots(NN)=130 GeV with the PHENIX detector at the Relativistic Heavy Ion Collider. The transverse momentum spectra were measured for minimum bias and for the 5% most central events. The (&ULambda;) over bar/Lambda ratios are constant as a function of p(T) and the number of participant

Hamburgers and chicken fillets were cooked in convection ovens, deep-fried or contact fried and analysed for mutagenic activity using the Ames test. For the three different convection ovens, the cooking parameters studied included the presence of steam, air velocity, air temperature and holding time. For deep-frying and contact frying, the cooking parameters included cooking temperature and cookin

OBJECTIVE: Acute neck pain developing over hours or a few days is often an alarming symptom that may be due to an inflammatory process or another process affecting the spine or the spinal canal, nerve roots, or peripheral nerves. MATERIALS AND METHODS: Four patients with acute onset of neck pain and dysphagia are presented. They were examined with MRI and CT, barium swallow, and plain radiography

A series of synthetic [2Fe-2S] complexes with terminal thiophenolate ligands and tethered ether or thioether moieties has been prepared and investigated in order to provide models for the potential interaction of additional donor atoms with the Fe atoms in biological [2Fe-2S] clusters. X-ray crystal structures have been determined for six new complexes that feature appended Et (1(C)), OMe (1(O)),
