Estimates of species extinction risk under climate change are generally based on differences in present and future climatically suitable areas. However, the locations of potentially suitable future environments (affecting establishment success), and the degree of climatic suitability in already occupied and new locations (affecting population viability) may be equally important determinants of ris

The "Coordination Action" ProDaC (Proteomics Data Collection) - funded by the EU within the 6(th) framework programme - was created to support the dissemination, utilization and publication of proteomics data. Within this international consortium, standards are developed and maintained to support extensive data collection by the proteomics community. An important part of ProDaC are workshops organ

Plastic wave propagation is studied during progressive plastic buckling of elastic viscoplastic slabs. The numerical results of the buckling behaviour are studied using two recent approaches for monitoring the plastic wave propagation. One method is a direct geometrical monitoring of the waves using a sequence of smooth approximations (geo-plot). The other method is a contour plot method (q-plot)

An examination of speech articulator movement used a video-based system for tracking & recording movement in three dimensions - the MacReflex(R). The system is noninvasive with no hazardous radiation or electromagnetic field, & no wires to impede movement. The facility is currently used at the Depts of Clinical Neurophysiology & Clinical Oral Physiology, U of Umea, to study strategies

Parks, remnants of natural habitats and other green areas are important for preserving biodiversity in urban areas. Here, we investigate the relative importance of habitat type and connectivity for butterfly species richness in the city of Malmo, Sweden. Further, we compare species richness and composition in the urban habitats with that in the surrounding agricultural landscape using previously p

To study the associations between intake of various types of fat and risk of prostate cancer (PCa) in a population-based cohort. We have studied 10,564 initially cancer-free men of the Malmo Diet and Cancer cohort, aged 45-73 years. Diet was assessed by a modified diet history method. Cases and clinical characteristics were ascertained via national and regional registry data. During a mean follow-

rECH1, a recently identified rat cDNA (FitzPatrick, D. R., Germain-Lee, E., and Valle, D. (1995) Genomics 27, 457-466) encodes a polypeptide belonging to the hydratase/isomerase superfamily, We modeled the structure of rECH1 based on rat mitochondrial 2-enoyl-CoA hydratase 1, The model predicts that rECH1p has the hydratase fold in the core domain and two domains for interaction with other subunit

The plasminogen activator (PA)/plasminogen activator inhibitor (PAI) system is believed to be involved in connective tissue remodelling in joint disease and both PA and PAI production has been shown in several cell types in the joint. We quantified immunoreactive PA and PAI in synovial fluid (SF) and correlated their levels to levels of cartilage derived proteoglycans, radiologically visible joint

Modal analysis is a widely accepted tool for non-destructive evaluation of mechanical properties of materials and structures. In this paper, a partial modal analysis is used to examine whether internal decay in living trees can be detected by studying the resonance frequencies of the trees. We examine the resonance frequencies of living spruce of species Picea abies (Norway spruce) by means of the

The aromatic beta-carbolines norharman and harman have been implicated in a number of human diseases including Parkinson's disease, tremor, addiction and cancer. It has been shown that these compounds are normal body constituents formed endogenously but external sources have been identified. Here, we summarise literature data on levels of norharman and harman in fried meat and fish, meat extracts,

The goal of this work was to investigate how internal and external forces acting on DNA affect the rate of genome ejection from bacteriophage λ after the ejection is triggered in vitro by a λ receptor. The rate of ejection was measured with time-resolved static and dynamic light scattering, while varying such parameters as temperature and packaged DNA length, as well as adding DNA-binding proteins

In order to obtain information on genes specifically expressed in the ectomycorrhizal symbiosis, 3,555 expressed sequence tags (ESTs) were analyzed from a cDNA library constructed from ectomycorrhiza formed between the basidiomycete Paxillus involutus and birch (Betula pendula). cDNA libraries from saprophytically growing fungus (3,964 ESTs) and from axenic plants (2,532 ESTs) were analyzed in par

Background: The lectin, phytohemagglutinin (PHA) has been shown to induce growth and functional maturation of the gastrointestinal (GI) tract in suckling rats. Objectives: To investigate the effect of the administration route, and whether enteral exposure to PHA was necessary to induce functional maturation. Methods: Fourteen-day-old rats were daily administered PHA via orogastric feeding (0.05 mg

P>Cytochromes of the c-type function on the outer side of the cytoplasmic membrane in bacteria where they also are assembled from apo-cytochrome polypeptide and haem. Two distinctly different systems for cytochrome c maturation are found in bacteria. System I present in Escherichia coli has eight to nine different Ccm proteins. System II is found in Bacillus subtilis and comprises four proteins: C

Down syndrome is a leading genetic cause of mental retardation. Here, we show high fractal dimensions and Lempel-Ziv complexity and lower minimum path fractal dimension (P

In the presence of a recyclable cationic exchange resin hydroxynitriles smoothly undergo a Pinner cyclization/hydrolysis two-step reaction in pure water to give lactones in good to excellent yields.

An algorithm is presented for the multiple crack problem in planar linear elastostatics. The algorithm has three important properties: it is stable, it is adaptive, and its complexity is linear. This means that high accuracy can be achieved and that large-scale problems can be treated. In a numerical example stress fields are accurately computed in a mechanically loaded material containing 10,000

In this work, we have evaluated the performance of a diffusion-sensitive fast spin-echo (FSE) pulse sequence. The proposed pulse sequence utilises velocity-compensating diffusion-encoding gradients and includes the collection of navigator echoes. Spoiler gradients were inserted in the slice-selecting direction to minimise effects from stimulated echoes. Calculations of the b values showed that cro
