A new European species of Pegomya Robineau-Desvoidy (Diptera : Anthomyiidae) near P-flavoscutellata (Zetterstedt)

A new species of Pegomya Robineau-Desvoidy is described from Europe ( Sweden, Denmark and Finland) by the name of P. curviphallis. It belongs, together with the Holarctic P. flavoscutellata (Zetterstedt) and the Nearctic P. flaviantennata Griffiths, in a species group defined by a sickle-shaped distiphallus. Differential descriptions are given for the two European species of the P. flavoscutellata

The neurobiology of cell transplantation in Parkinson's disease

Over the past decade, neural grafting has emerged as a new treatment option for Parkinson's disease. When performed successfully, grafts of human embryonic neural tissue can give rise to major symptomatic relief in patients, However, a recent report on a double-blind placebo control study, which received worldwide attention, described less pronounced beneficial effects of the grafts, and found the

Cosmogenic Be-10-ages from the Store Koldewey island, NE Greenland

Earlier work in northeast Greenland has suggested a limited advance of the Greenland Ice Sheet during the Last Glacial Maximum (LGM). However, this concept has recently been challenged by marine geological studies, indicating grounded ice on the continental shelf at this time. New Be-10-ages from the Store Koldewey island, northeast Greenland, suggest that unscoured mountain plateaus at the outer

Tissue microarray based analysis of prognostic markers in invasive bladder cancer: Much effort to no avail?

PURPOSE: To evaluate altered protein expression with tissue microarray methodology for 15 different markers with potential prognostic significance in invasive bladder cancer. MATERIALS AND METHODS: Invasive tumor was sampled with the tissue-arraying instrument in 133 consecutive patients who underwent radical cystectomy, and at least 3, 0.6-mm tissue cores were obtained. With immunohistochemistry,

Effects of temperature on UV-B-induced DNA damage and photorepair in Arabidopsis thaliana

DNA damage in the form of cyclobutane pyrimidine dimers(CPDs) and (6-4) photoproducts(6-4PPs) induced by UV-B radiation in Arabidopsis thaliana at different temperatures was investigated using ELISA with specific monoclonal antibodies. CPDs and 64PPs increased during 3 h UV-B exposure, but further exposure led to decreases. Contrary to the commonly accepted view that DNA damage induced by UV-B rad

Personalised nutrition : status and perspectives

Personalised, genotype-based nutrition is a concept that links genotyping with specific nutritional advice in order to improve the prevention of nutrition-associated, chronic diseases. This review describes the current scientific basis of the concept and discusses its problems. There is convincing evidence that variant genes may indeed determine the biological response to nutrients. The effects of

Non-linear regional relationships between climate extremes and annual mean temperatures in model projections for 1961-2099 over Europe

A simple method is tested for scaling climate-extreme results from high resolution regional climate models (RCMs) to time-periods and emission scenarios for which the RCMs have not been run. The 30 yr mean relationships between indicators of extremes (IoEs) and annual mean daily maximum temperature (T-xa) are investigated. Such relationships from the UK Met Office Hadley Centre RCM HadRM3P, along

Contractures induced by reversed Na+/Ca2+ exchange in rat portal vein: effects of calcium antagonists

Spontaneous electrical and mechanical activity was abolished in isolated preparations of rat portal vein by exposure to K+-free Krebs solution. This procedure probably also increased the intracellular [Na+] owing to interference with the active transmembrane Na+-K+ transport. Contractures could be induced under these conditions by lowering extracellular [Na+] from the control level of 144 to 17 mM

A complex system of ligaments and a muscle keep the crystalline lens in place in the eyes of bony fishes (teleosts).

The suspension of the crystalline lens in the eye was studied in 11 species of teleost (bony fish) from 10 families and 7 orders by light and electron microscopy. In all species there were 4-5 ligaments in about the equatorial plane of the eye, in which also the tendon of the retractor lentis muscle attaches to the lens. In two cichlid species two additional ligaments were found running from the m

Reduced inhibition of enzymatic hydrolysis of steam-pretreated softwood

Softwood constitutes the main source of lignocellulosic material in Sweden which can be used for ethanol production from renewable resources. To make the biomass-to-ethanol process more economically feasible, it is preferable to include the sugar-rich prehydrolysate, i.e. the liquid obtained after the pretreatment step, in the enzymatic hydrolysis of the solid fraction. This study shows that the p

The State in European Employment Regulation

The aim of the paper is to examine the changing role of the state in employment regulation in an environment that has become more market-driven and Europeanised since the introduction of the European Monetary Union (EMU) and the European Employment Strategy (EES). The point of departure is a general discussion of the role of the state in capitalist development and a review on the recent debate on

Galectin-inhibitory thiodigalactoside ester derivatives have antimigratory effects in cultured lung and prostate cancer cells.

Aromatic 3,3'-diesters of thiodigalactoside were synthesized in a rapid three-step sequence from commercially available thiodigalactoside and evaluated as inhibitors of cancer- and immunity-related galectins. For each of galectins-1, -3, -7, and -9N-terminal domain, aromatic 3,3'-diesters of thiodigalactoside were found to have affinities in the low micromolar range, which represents a 7-70 fold e

A non-existence result for the Ginzburg-Landau equations

We consider the stationary Ginzburg–Landau equations in Rd, d=2,3. We exhibit a class of applied magnetic fields (including constant fields) such that the Ginzburg–Landau equations do not admit finite energy solutions.

A model of triploid endosperm evolution driven by parent-offspring conflict

The parental investment in angiosperms comprises the endosperm, a nutrient reserve that is used during seed development. The endosperm contains genes from both parents. The most common endosperm form is the 3n Polygonum-type with more maternal genetic influence than paternal, i.e. with two maternal nuclei and one paternal nucleus. The evolutionary original state is thought to be a diploid endosper

Moisture diffusivities evaluated at high moisture levels from a series of water absorption tests

This paper presents measured moisture diffusivities for sedimentary calcareous sandstone, lime silica bricks, bricks, and autoclaved, aerated concrete. The moisture diffusivities were calculated from the relation between the water sorption coefficients and the initial water content in the specimen before testing. The method used is based on Boltzmann transformation. The relation between the water

Census of binaries - The big picture

Gaia will observe huge numbers of binaries with a large range of periods. The present contribution tries to present some estimates of the expected number of detections and/or orbit determinations, based on simplified but large-scale simulations. The simulations have to model both a Galaxy with binaries, the instrument and observations, and the reduction programs. As in previous studies, there are

Neuropeptide Y co-exists with vasoactive intestinal polypeptide and acetylcholine in parasympathetic cerebrovascular nerves originating in the sphenopalatine, otic, and internal carotid ganglia of the rat

Neuropeptide Y co-exists with noradrenaline in the majority of the sympathetic nerves supplying cerebral blood vessels. However, after sympathectomy in the rat the number of cerebrovascular neuropeptide Y nerve fibers are only reduced in number despite a complete disappearance of the adrenergic markers. The origin of these non-sympathetic neuropeptide Y fibers was studied by nerve transections and
