Neurodevelopmental outcome at 5 years of age of a national cohort of extremely low birth weight infants who were born in 1996-1997

Objective. Increasing survival of extremely low birth weight (ELBW; birth weight < 1000 g) infants raises a concern regarding the risks of adverse long-term outcome such as cognitive dysfunction. Few studies have reported long-term follow-up of representative regional cohorts. The objective of this study was to assess the 5-year outcome of a prospectively followed national ELBW infant cohort. Meth

Megalin is a receptor for apolipoprotein M and kidney-specific megalin-deficiency confers urinary excretion of apolipoprotein M.

Apolipoprotein ( apo) M is a novel apolipoprotein belonging to the lipocalin protein superfamily, i.e. proteins binding small lipophilic compounds. Like other apolipoproteins, it is expressed in hepatocytes and secreted into plasma where it associates with high-density lipoprotein particles. In addition, apoM is expressed at high levels in the kidney tubule cells. In this study, we show that the m

NADH electrooxidation using carbon paste electrodes modified with nitro-fluorenone derivatives immobilized on zirconium phosphate

The basic electrochemistry of carbon paste electrodes modified with two new redox mediators, nitro-fluorenone derivatives, one neutral and one negatively charged, adsorbed on zirconium phosphate has been studied as well as their ability to oxidize NADH electrocatalytically. Cyclic voltammetry of these chemically modified electrodes performed in different aqueous buffer solutions at different pHs r

A prospective study on antibody response to repeated vaccinations with pneumococcal capsular polysaccharide in splenectomized individuals with special reference to Hodgkin's lymphoma

Background. Splenectomy is accompanied by a life-long risk of overwhelming postsplenectomy infection (OPSI), mainly caused by polysaccharide (PS) encapsulated bacteria such as Streptococcus pneumoniae. Despite extensive prophylactic efforts the mortality and morbidity rates remain high. The present study was based on a strategy with a predefined vaccination algorithm including repeated 23-valent p

Molecularly imprinted CEC sorbents: investigations into polymer preparation and electrolyte composition.

The influence of the sorbent preparation protocol and separation parameters on the selectivity and chromatographic efficiency of super-porous molecularly imprinted polymer (MIP) monoliths in capillary electrochromatography (CEC) was studied. Chiral templates were employed and enantiomer separation and resolution were used as measures of imprint selectivity and column efficiency, respectively; the

Patellar fractures. A 30-year follow-up

Forty patients who had had a patellar fracture during the years 1950-58 were reevaluated 30 years later. A clinical and radiographic examination was performed. Fourteen patients had subjective complaints. Two thirds of the patients who had more than 2-mm diastasis or 1-mm incongruity had complaints and reduced quadriceps strength. Radiographically, all the patients had a reduction in the lateral p

Determination of natural radiative lifetimes and Lande factors for highly excited F states in cesium

Natural radiative lifetimes and LandégJ factors for several highly excitedF states in cesium were measured using time-resolved fluorescence spectroscopy. TheF states were excited from the 52D5/2 state with a pulse-modulated CW dye laser, and the delayed-coincidence method was employed to record decay curves, which in some experiments exhibited Zeeman quantum beats. A further CW dye laser was used

Anion-exchange supermacroporous monolithic matrices with grafted polymer brushes of N,N-dimethylaminoethyl-methacrylate

Graft polymerization using potassium diperiodatocuprate as initiator was found to be an effective and convenient method for grafting functional polymer of N,N-dimethylaminoethyl methacrylate (DMAEMA) onto superporous polyacrylamide gels, so-called cryogels (pAAm cryogels). It was possible to achieve grafting degrees up to 110% (w/w). The two-step graft polymerization i.e. first activation of the m

Metastable hydrogen absorption in ejecta close to eta Carinae

Spectroscopy with the high spatial resolution of the Hubble Space Telescope (HST) reveals narrow absorption in the hydrogen Balmer lines in spectra of Eta Carinae and the nearby nebular-scattered starlight. While hydrogen Balmer absorption lines are seen in stellar photospheres and winds, we are not aware of such being seen in galactic nebulae. This exceptional case is caused by intense stellar UV

Century-scale changes of atmospheric CO2 during the last interglacial

The crucial role of atmospheric CO2 in glacial-interglacial transitions is demonstrated by recent ice-core studies that highlight the importance of accurate CO2 records for our understanding of Quaternary climate dynamics. Previous estimates of CO2 levels during the last interglacial stage (the Eemian) relied on measurements on air trapped in the Antarctic Vostok ice core. Due to uncertainties ass

Measurement of charm and beauty photoproduction at HERA using D*mu correlations

A measurement of charm and beauty photoproduction at the electron proton collider HERA is presented based on the simultaneous detection of a D*(+/-) meson and a muon. The correlation between the D* meson and the muon serves to separate the charm and beauty contributions and the analysis provides comparable sensitivity to both. The total and differential experimental cross sections are compared to

A folding variant of human alpha-lactalbumin induces mitochondrial permeability transition in isolated mitochondria

A human milk fraction containing multimeric alpha-lactalbumin (MAL) is able to kill cells via apoptosis. MAL is a protein complex of a folding variant of alpha-lactalbumin and lipids. Previous results have shown that upon treatment of transformed cells, MAL localizes to the mitochondria and cytochrome c is released into the cytosol. This is followed by activation of the caspase cascade. In this st

Enriched environment enhances recovery of motor function after focal ischemia in mice, and downregulates the transcription factor NGFI-A.

The purpose of this study was to investigate the effect of enriched environment on motor function after experimental stroke in mice, and to determine whether time in enriched environment affects functional recovery. Earlier investigations have shown that rats placed in an enriched environment after focal ischemia, remarkably improve motor function, but similar observations in mice have not been re
