BACKGROUND: Simultaneous contact allergies to epoxy resins based on diglycidyl ether of bisphenol A (DGEBA-R) or epoxy resins of the bisphenol F-type and the reactive diluent phenyl glycidyl ether (PGE) have been reported. The reason might be cross-reactivity, exposure to an epoxy resin system with PGE as a component, or contamination by PGE in the epoxy resin. AIMS: To study contamination by PGE,

Naive male and female silver Y moths, Autographa gamma (Lepidoptera: Noctuidae), were attracted in a flight tunnel assay to potted creeping thistle, Cirsium arvense (Asteraceae), butterfly-orchid, Platanthera bifolia (Orchidaceae), soapwort, Saponaria officinalis (Caryophyllaceae), greater knapweed, Centaurea scabiosa (Asteraceae), red clover, Trifolium pratense (Fabaceae), and catnip, Nepeta faas

Concentrations of lead (Pb) in blood (B-Pb, geometric mean 34.6 micrograms l-1, n = 127) and inorganic arsenic (As) and its metabolites in urine (U-As, mean 5.1 micrograms/g creatinine, n = 35) did not differ between children living in a village close to a glassworks emitting both Pb and As and children living in a reference area. There was no significant effect on B-Pb and U-As related to parents

Objective: Reduced serum adiponectin levels have been found in obesity and type 2 diabetes and variations in the adiponectin gene (APM1) have been associated with type 2 diabetes and features of the metabolic syndrome in different populations. Study Design: Here, we investigated the expression of APM1 in adipose tissue and studied the relationship between variation in APM1 expression, the APM1 G27

In the past, open surgical techniques such as thrombectomy and bypasses were the treatments of choice for acute and chronic venous occlusive disease of the iliocaval vein segments, but the results were often disappointing. With the introduction of endovascular techniques in the 1990s, open techniques were widely replaced by endovascular interventions. Proper preoperative imaging with computed tomo

We have examined the expression and activity of inducible nitric oxide synthase ( iNOS) and the activity of neuronal constitutive NOS ( ncNOS) in isolated rat pancreatic islets, stimulated by a "hyperglycaemic" concentration of glucose, and whether the NOS activities could be modulated by activation of the cyclic AMP/ protein kinase A ( cyclic AMP/PKA) system in relation to the insulin secretory p

Decompression illness (DCI) is an illness affecting divers subjected to reductions in ambient pressure. Besides a mechanical explanation to DCI, an inflammatory mechanism has been suggested. In this study, levels of interleukin (IL)-8, IL-6, IL-1 receptor antagonist (IL-1ra), secretory leukocyte protease inhibitor (SLPI), and neutrophil gelatinase-associated lipocalcin (NGAL) were measured in dive

Although the assembly of a ternary complex between the SNARE proteins syntaxin-1, SNAP25 and VAMP2 is known to be crucial for insulin exocytosis, the mechanisms controlling this key event are poorly understood. We found that pancreatic beta-cells express different isoforms of tomosyn-1, a syntaxin-1-binding protein possessing a SNARE-like motif. Using atomic force microscopy we show that the SNARE

We solve a nonequilibrium statistical-mechanics problem exactly, namely, the single-file dynamics of N hard-core interacting particles (the particles cannot pass each other) of size Delta diffusing in a one-dimensional system of finite length L with reflecting boundaries at the ends. We obtain an exact expression for the conditional probability density function rho T(yT,t vertical bar yT,0) that a

This paper examines the significance of the schematic domain of BOUNDEDNESS in adjectives. It is proposed that boundedness in adjectives is a fundamental characteristic associated with gradability. Cross-categorial correspondences are made to nouns and verbs, where boundedness is a feature of countability and aktionsart respectively. Two basic types of gradable adjectives are distinguished: those

The Bacillus subtilis aprE leader is a determinant of extreme mRNA stability. The authors examined what properties of the aprE leader confer stability on an mRNA. The secondary structure of the aprE leader mRNA was analysed in vitro and in vivo, and mutations were introduced into different domains of an aprE leader-lacZ fusion. The half-lives of the corresponding transcripts were determined and be

The second messenger cAMP mediates potentiation of glucose-stimulated insulin release. Use of inhibitors of cAMP-hydrolyzing phosphodiesterase (PDE) 3 and overexpression of PDE3B in vitro have demonstrated a regulatory role for this enzyme in insulin secretion. In this work, the physiological significance of PDE3B-mediated degradation of cAMP for the regulation of insulin secretion in vivo and glu

Software process improvement often lacks strong links to project management and control activities, which are concerned with identifying the need of process change and triggering improvement initiatives. Project management, on the other hand, often fails at selecting appropriate software engineering methods and technology that help to ensure project success. This paper proposes a model that guides

Proton-detected NMR diffusion and P-31 NMR chemical shifts/bandwidths measurements were used to investigate a series of liposomal formulations where size and PEGylation extent need to be controlled for ultrasound mediated drug release. The width of the P-31 line is sensitive to aggregate size and shape and self-diffusion H-1 NMR conveys information about diffusional motion, size, and PEGylation ex

The breakup of 12Be into 6He+6He and 4He+8He has been studied using a 378 MeV 12Be beam inelastically excited by 12C and (CH2)n targets. The measurements indicate that breakup occurs from rotational states in the 10 to 25 MeV excitation energy interval, with spins in the range of 4ħ to 8ħ. The inferred moment of inertia is consistent with the cluster decay of an exotic molecular structure in 12Be,

The mechanical properties of polystyrene/polyamide-6 (50/50 wt/wt) blends were improved by additions of small amounts of poly(styrene-g-ethylene oxide) (SEO) during compounding by extrusion. Tensile testing of injection-molded samples revealed that the blends developed a yield point after addition of 1 wt % SEO. The elongation at break increased by almost a factor of 6, and the impact strength inc
