Amphiphilic graft copolymers were prepared via the radical copolymerization of poly(ethylene oxide) (PEO) macromonomers with fluorocarbon or hydrocarbon acrylates in toluene with 2,2 ' -azobisisobutyronitrile (AIBN) as an initiator. H-1 NMR spectroscopy confirmed that the composition of the graft copolymers corresponded well to the monomer feed. For gel electrolytes prepared from the amphiphilic c

Recently, we and others reported a recurrent t(7;12)(q36;p13) found in myeloid malignancies in children < or =18 months of age and associated with a poor prognosis. Fluorescence in situ hybridization studies mapped the 12p13 breakpoint to the first intron of ETV6 and narrowed down the region of 7q36 involved. By using the sequences made public recently by the Human Genome Project, two candidate ge

A gastrostomy device is removed from the gastrostoma when no longer needed. The aim of the study was to test the hypothesis of whether it is possible for the surgeon to decide which stoma has to be closed with a gastroraphy and which to leave for a spontaneous closure within a reasonable period of time. Out of a cohort of 321 patients, who had been operated with a video-assisted gastrostomy, we in

There is now considerable evidence for the involvement of K+ channels in nitric oxide (NO) induced relaxation of smooth muscles including the myometrium. In order to assess whether apamin-sensitive K+ channels play a role in NO - induced relaxation of the human uterus, we have studied the effect of specific blockers of these channels on the relaxation of myometrium from non-pregnant women. In vitr

The Eae2 locus on mouse chromosome 15 controls the development of experimental autoimmune encephalomyelitis (EAE); however, in this study we show that it also controls collagen-induced arthritis (CIA). To find the smallest disease-controlling locus/loci within Eae2, we have studied development of CIA in 676 mice from a partially advanced intercross. Eae2 congenic mice were bred with mice congenic

OBJECTIVE-To report the incidence of sight-threatening vascular lesions in type 2 diabetic subjects without retinopathy after adopting a 3-year interval screening program. RESEARCH DESIGN AND METHODS-In all, 1,691 type 2 diabetic subjects with no detectable retinopathy in two 50 degrees red-free fundus photographs were scheduled for follow-up with photography 3 years later. Age at diabetes diagnos

We investigated the wear characteristics and clinical performance of four different total hip joint articulations in 114 patients. Wear and migration was measured by roentgenstereophotogrammetric analysis at five years or at the last follow-up. The mean annual wear was 0.11 mm for a stainless steel/Enduron articulation, 0.34 mm for stainless steel/Hylamer cup, 0.17 mm for zirconium oxide ceramic/E

In the 1990s, two randomised clinical trials started in Scandinavia addressing whether hormone replacement therapy (HRT) is safe for women with previous breast cancer. We report the findings of the safety analysis in HABITS (hormonal replacement therapy after breast cancer-is it safe?), an open randomised clinical trial with allocation to either HRT or best treatment without hormones. The main end

Four green microalgae (Chlorella sorokiniana, Chlorella vulgaris, Scenedesmus obliquus and Selenastrum capricornutum), a wild Bolivian microalga strain and two cyanobacteria (Anabaena catenula and Microcystis aeruginosa) were compared for tolerance to salicylate, O2 production capacity and ability to support salicylate degradation by a Ralstonia basilensis strain in symbiotic microcosms with the m

Compensation behaviour is established for the gas phase hydrodehalogenation of a range of haloarenes over a common Ni/SiO2 catalyst. Analysis of the experimental results delivers an isokinetic temperature (T-iso) at 658 +/- 2K associated with the following reactants: chlorobenzene, 4-chlorotoluene, 3-chlorophenol, 1,3,-dichlorobenzene, 4-chlorophenol, 3,5-dichlorophenol, 1,4-dichlorobenzene, bromo

Objectives: To describe change in functional ability in the oldest-old population during 3 years and examine its relation to life satisfaction (LS). A total of 681 individuals aged 78 and older from the population-based study Good Aging in Skane took part. Methods: Functional ability was assessed using Sonn and Asberg's Activities of Daily Living (ADL) scale and related to LS assessed by Neugarten

The literature on trade facilitation has mostly focused on implications for trade volumes. However, recent theoretical contributions have emphasized that trade costs – such as transaction costs related to cross-border trade procedures – affect both the traded volumes of “old” goods (the intensive margin) and the range of traded goods (the extensive margin). This paper therefore tests whether trade

A highly scattering porous ceramic sample is employed as a miniature random-scattering multipass gas cell for monitoring of oxygen content in opaque media, that is, wood materials in the present work. Gas in scattering media absorption spectroscopy is used by employing a 760 nm near-infrared laser diode to probe the absorption of molecular oxygen enclosed in the pores of the ceramic material worki

The question whether very weak, low frequency magnetic fields can affect biological matter is still under debate. The theoretical possibility of such an interaction is often questioned and the site of interaction in the cell is unknown. In the present study, the influence of extremely weak 60?Hz magnetic fields on the transport of Ca2+ was studied in a biological system consisting of highly purifi
