Fuel reserves affect migratory orientation of thrushes and sparrows both before and after crossing an ecological barrier near their breeding grounds

Fat reserves influence the orientation of migrating songbirds at ecological barriers, such as expansive water crossings. Upon encountering a body of water, fat migrants usually cross the barrier exhibiting 'forward' migration in a seasonally appropriate direction. In contrast, lean birds often exhibit temporary 'reverse' orientation away from the water, possibly to lead them to suitable habitats f

A comparative genetic analysis between collagen-induced arthritis and pristane-induced arthritis.

Objective To compare the genetic regulation of collagen-induced arthritis (CIA) with that of pristane-induced arthritis (PIA) in rats. Methods A genome-wide linkage analysis of an (E3 × DA)DA backcross of rats with CIA (n = 364 male rats; the same strain combinations as previously used to determine the genetic control of PIA) was performed. The strongest loci in both CIA and PIA (i.e., Cia12/Pia4

Impact of different aspects of social participation and social capital on smoking cessation among daily smokers: a longitudinal study.

Objective: To investigate differences in different aspects of social participation and social capital among baseline daily smokers that had remained daily smokers, become intermittent smokers, or stopped smoking at one year follow up. Design/setting/participants/measurements: 12 507 individuals, aged 45–69 years, interviewed at baseline between 1992 and 1994 and at a one year follow up were inve

Neuropeptide Y stimulates proliferation of human vascular smooth muscle cells: cooperation with noradrenaline and ATP

Since the sympathetic nervous system has been shown to exert a trophic influence on vascular smooth muscle cells (SMC), we studied the growth regulating effects of neuropeptide Y (NPY) in cooperation with the sympathetic co-transmitters noradrenaline and adenosine triphosphate (ATP) in human vascular SMC. NPY stimulated DNA synthesis in human SMC grown from subcutaneous arteries and veins (diamete

Weight-setting and quality assessment in simultaneous graphic generalization

Cartographic generalization aims at simplifying the representation of data to suit the scale and purpose of the map. This paper deals with a method that implements the whole graphic generalization process (roughly defined as the operators simplification, smoothing, exaggeration and displacement) called simultaneous graphic generalization. This method is based on constraints, i.e. requirements that

A multitechnique study of the interactions between H+, Na+, Ca2+ and Cu2+, and two types of softwood Kraft fibre materials

Aiming for a better understanding of the interactions between water suspended cellulose fibres and metal ions, this study was focused on characterising the interactions between Ca2+. Cu2+ and two different fibre materials-a fully bleached softwood Kraft pulp, and a chemically modified fully bleached softwood Kraft fibre material. The study was conducted as a function of pH (2-7), and both in the a

Air contaminants in a submarine equipped with air independent propulsion

The Swedish Navy has operated submarines equipped with air independent propulsion for two decades. This type of submarine can stay submerged for periods far longer than other nonnuclear submarines are capable of. The air quality during longer periods of submersion has so far not been thoroughly investigated. This study presents results for a number of air quality parameters obtained during more th

Decoration of amyloid fibrils with luminescent conjugated polymers

In this work we report the coating of a biological template with a polar, but uncharged,luminescent conjugated polymer, soluble in organic solvents but not in water, to produce a nanowire. Amyloid fibrils from bovine insulin were decorated with an alternating polyfluorene derivative. Decorated fibrils were partially aligned on hydrophobic surfaces as separate and bundled fibrils, by means of molec

Increased subpopulations of CD16(+) and CD56(+) blood monocytes in patients with active Crohn's disease

Background: Circulating monocytes may be subdivided according to the presence or absence of the Fc gamma receptor CD16 and the neural cell adhesion molecule CD56. Monocytes classified into these subpopulations Lire characterized by distinct phenotypic and functional features. We hypothesized that patients with active Crohn's disease differ in their peripheral monocyte subpopulations. Methods: Usin

Ptiliidae of the Maritime Provinces of Canada (Coleoptera): new records and bionomic notes

The Ptiliidae of the Maritime Provinces of Canada is surveyed. Twenty-nine new provincial records from the Maritime Provinces of Canada are reported including the first records of the family from Prince Edward Island. Fourteen species are recorded for the first time for the Maritime Provinces as a whole. Acrotrichis josephi (Matthews) is recorded for the first time in eastern North America and Acr

Assessment and evaluation of individual prerequisites for dental education

Since 2001 the School of Dentistry of Malmö University in Sweden has used an alternative procedure based on results of an investigation supported by the Swedish Council for the Renewal of Undergraduate Education. The investigation concerned possibilities of predic¬ting school performance on the basis of an interview, as well as tests of general intelligence, spatial ability, manual dexterity, empa

Attentional bias for negative self-words in young women The role of thin ideal priming and body shape dissatisfaction

Previous research suggests that body dissatisfied women are particularly susceptible to negative affect following exposure to thin media images, whereas body satisfied women may even respond positively to such images. It was thus hypothesised that negative self-referent information would be more accessible in body dissatisfied women than in women satisfied with their bodies after viewing thin idea

Contact allergy to the active ingredients of Bioban P 1487

Bioban P 1487, consisting of the 2 active ingredients 4-(2-nitrobutyl)-morpholine (M) and 4,4'-(2-ethyl-2-nitro-1,3-propanediyl)-bis morpholine (DM), is a preservative recommended for mental working fluids. The aims of this study were to assess the frequency of contact allergy to Bioban P 1487, when added to a standard patch test series, as well as to test the individual active ingredients in pati

Restoration of the striatal dopamine synthesis for Parkinson's disease: viral vector-mediated enzyme replacement strategy.

arkinson's disease is the second most common neurodegenerative disease. It is charaterized by a progressive loss of dopamine (DA) producing neurons in the midbrain, which result in a decline of DA innervations present in the forebrain, in particular, the striatum. The disease leads to appearance of motor symptoms involving akinesia/bradykinesia, gait disturbances, postural imbalance and tremor. Or
