Molecular factors control the developmental ingrowth of axons to the tooth pulp. Here we examine the ability of pulpal cells to induce neurite outgrowth from neonatal rat trigeminal neurones (TGNs) in vitro. We found that TGNs emitted neurites and formed networks of branches in relation to pulpal cells. Neurones co-cultured with a mixture of pulpal cells and 3T3 fibroblasts formed networks exclusi
An experimental system was developed for the rapid measurement of the aspiration/transfer efficiency of aerosol samplers in a wind tunnel. We attempted to measure the aspiration and particle transfer characteristics of two inlets commonly used for sampling airborne Particulate Matter ( PM): the 'Total Suspended Particulate' or TSP inlet, and the louvered 'dichotomous sampler inlet' typically used
Cladribine has single-drug activity in acute myeloid leukaemia (AML), and may enhance the formation of the active metabolite (ara-CTP) of cytosine arabinoside (ara-C). To evaluate the feasibility of adding intermittent cladribine to intermediate-dose ara-C (1 g/m(2)/2 h) b.i.d. for 4 d with idarubicin (CCI), we performed a 2:1 randomized phase II trial in AML patients aged over 60 years. Primary e
General bonding principles are used to predict the structure of individual nanocrystals in nanocrystalline materials with semiionic bonding. The relationship between the general principles and actual nanocrystal structures is demonstrated using titanium dioxide in the anatase form. The proposed nanocrystals simultaneously fulfill strict criteria of stoichiometry, high coordination, and balanced ch
The use of continuous prognostic variables is clinically impractical, and arbitrarily chosen cut-off points can result in a loss of prognostic information. Here we report findings from a study of primary breast cancer, showing how the prognostic value of the fraction of cells in the S-phase of the cell cycle (SPF), as measured by flow cytometry, can be affected by the SPF cut-off level(s) adopted.
The Homogeneous Charge Compression Ignition Engine, HCCI has the potential to combine the best of the Spark Ignition and Compression Ignition Engines. With high octane number fuel, the engine operates with high compression ratio and lean mixtures giving Cl engine equivalent fuel consumption or better. Owing to pre-mixed charge without rich or stoichiometric zones, the production of soot and NO, ca
The apposition compound eye of a nocturnal bee, the halictid Megalopta genalis, is described for the first time. Compared to the compound eye of the worker honeybee Apis mellifera and the diurnal halictid bee Lasioglossum leucozonium, the eye of M. genalis shows specific retinal and optical adaptations for vision in dim light. The major anatomical adaptations within the eye of the nocturnal bee ar
Lipooligosaccharide (LOS) heptose (Hep) glycan substitutions influence gonococcal serum resistance. Several gonococcal strains bind the classical complement pathway inhibitor, C4b-binding protein (C4BP), via their porin (Por) molecule to escape complement-dependent killing by normal human serum (NHS). We show that the proximal glucose (Glc) on HepI is required for C4BP binding to Por1B-bearing gon
A persistent vegetative state (severe dementia) developed in a 30-year-old man following hypoglycemic coma. Despite the poor clinical outcome, sensory evoked response recovered between 6 and 34 months after the insult. The cerebral blood flow level at rest after 34 months was slightly above the normal range. This finding contrasts with the low cerebral blood flow regularly reported in patients who
Background: The goal of this study was to investigate whether Interactive Voice Response is a technology with which to perform real-time assessments of alcohol consumption and stress. Methods: Fifteen subjects (men and women) were recruited from a previous 4-year intervention study (n = 2,032). The Interactive Voice Response technique was based on mobile telephones. During 1 week, stress and alcoh
The S-phase fraction (SPF) in flow cytometric DNA histograms in soft tissue sarcoma (STS) can be calculated in various ways. The traditional planimetric method of Baisch has been shown to be prognostic, but is hampered by a failure rate of around 40%. We therefore tested other models to see if this rate could be decreased with retained prognostic value. In 259 STS of the locomotor system the SPF w
The interaction between fungal laccases from Trametes basidiomycetes and different lignins has been studied using electrochemical and chromatographic methods. The kinetic parameters for the oxidation reaction of hydroquinone and for Kraft lignin by molecular oxygen catalysed by Trametes hirsuta laccase have been investigated. Polymerisation of lignin by laccase was shown. The process was independe
This paper draws on extensive theoretical research and literature reviews, and presents two cases to illustrate practical applications. It addresses the problem of how learning both from extracorporate sources, like universities, as well as across internal corporate functions, like R&D and manufacturing, can enhance company flexibility and performance in innovation. This paper aims at deliveri
In fragmented landscapes, mobility is an important trait for population persistence but the predictions on the relationship between habitat fragmentation and extinction risk are contradictory. Here, we test the effects of the two main aspects of fragmentation, patch area and isolation, on the species richness of groups of butterflies associated with semi-natural grasslands, differing in mobility.
The aim of the study was to investigate the effects of estradiol and tamoxifen alone and in combination on the estrogen binding site status of the urogenital tract in the rabbit. Bilaterally ovariectomized rabbits were divided into four groups of six. Wereas the control group received no treatment, the remaining rabbits were treated with estrogen orland tamoxifen. Cytosolic and nuclear fractions w
