The biota of herbivorous arthropods and pathogenic microorganisms associated with Rosa rugosa in its native and exotic ranges is reviewed. This is done as an initial step towards the identification of potential agents for biological control of this plant species invasive in Europe and North America. It is shown that more insect (but apparently not fungal) species attack R. rugosa in its native ran

The scheme of concepts we employ in daily life to explain intentional behaviour form a belief-desire model (BD model), in which motivating states are sorted into two suitably broad categories. The BD model embeds a philosophy of action, i.e. a set of assumptions about the ontology of motivation with subsequent restrictions on psychologising and norms of practical reason. A comprehensive critique o

Boundary issues are central to globalisation - the expansion and time-space integration of human societies - and to both biological and cultural diversity. The latter are, in turn, intrinsically related in processes of coevolution that generate change in the patchwork quilt of cultural and natural landscapes. These processes are especially discernible in small island societies. This paper argues t

ABSTRACT Optimal breeding of mice is very important in biomedical science today. The understanding why some strains breed better and some worse enable scientists to create better in vivo models for human diseases. The aim of this thesis was to identify and characterize new genetic regions linked to reproductive performance and autoimmune inflammation in female mice. Collagen-induced arthritis (CIA

A peptide derived from the N-terminus of the unprocessed bovine prion protein (bPrPp), incorporating the hydrophobic signal sequence (residues 1-24) and a basic domain (KKRPKP, residues 25-30), internalizes into mammalian cells, even when coupled to a sizeable cargo, and therefore functions as a cell-penetrating peptide (CPP). Confocal microscopy and co-localization studies indicate that the inter

Soil solution is the direct source of mineral nutrients to vascular plants. Soil solutions of sieved samples at water-holding capacity of a seminatural calcareous soil, never cultivated or treated by fertilizers, were collected by sequential centrifugation at 24-18,900 X g relative centrifugal force (RCF), followed by ultrafiltration (0.2 mu m), and analysed for Al, Ca, Fe, K, Mg, Mn, Mo, Na, P, S

A series of samples of vanadia supported on monoclinic zirconia were prepared with nominal loadings from a half up to sixteen theoretical vanadia layers. The samples were characterized with X-ray diffraction, scanning electron microscopy combined with energy dispersive X-ray analysis, high-resolution electron microscopy, Raman and diffuse reflectance infrared spectroscopy, and were used in the oxi

Twenty-five patients with isolated unilateral cleft lip took part in a follow-up study at a mean age of 28.6 years. All had had a primary, Millard lip repair, at a mean age of 4.6 months. In 20 patients, at least one secondary correction had been undertaken during adolescence. The overall long-term outcome was thought to be good, leaving a fairly inconspicuous fine lip scar and acceptable nose con

Low molecular weight protein tyrosine phosphatase (LMW-PTP) dimerizes in the phosphate-bound state in solution with a dissociation constant of K-d = 1.5(+/-0.1) mM and an off-rate on the order of 10(4) s(-1).H-1 and N-15 NMR chemical shifts identify the dimer interface, which is in excellent agreement with that observed in the crystal structure of the dimeric S19A mutant. Two tyrosine residues of

In 44 consecutive patients with systemic sclerosis (SSc), plasma concentrations of von Willebrand factor (vWf) were higher than those of the vWf propeptide, but the propeptide showed less variability within patient subgroups. Higher values of the propeptide were observed in patients with early pulmonary involvement. A closer correlation of the propeptide than of vWf to biochemical markers of activ

Heating equimolar mixtures of Sb2O3 and V2O5 at 800 degrees C in flowing gas with varying O-2/N-2 ratios produces a continuous nonstoichiometric series of rutile type, i.e., Sb(0.9)V(0.9+x)square(0.2-x)O(4), 0 < x < 0.2, and varying amounts of alpha-Sb2O4. Oxidized Sb(0.9)V(0.9)square(0.2)O(4), a = 4.63, c = 3.03 Angstrom (X ray powder data, XRD), is formed in pure oxygen and exhibits a modulated

Supported lipid membranes are particularly attractive for use in biochemical assays because of their resistance to nonspecific adsorption and their unique ability to host transmembrane proteins. Although ideal for use in many surface-based detection techniques, supported bilayers can make the incorporation of proteins problematic due to the steric constraints of the underlying substrate. A recentl
