Morphometric relationships between populations of Papaver radicatum within the southern Norwegian mountains were investigated using canonical variates analysis and Ward's clustering on capsule and leaf character sets. The survey describes patterns of variation among 13 wild-scored populations from five geographically disjunct localities, usually assigned to five races or subspecies. Our results fr
There is a geographic separation of the 2 pollen morphs in European Silene latifolia, with the changeover zone running NW-SE from the Netherlands to Greece. Reticulate grains are characteristic of western populations, microechinate grains of eastern populations. -from AuthorsDept of Population & Evol Biol, Univ of Utrecht, Padualaan 8, 3584 CH Utrecht, The Netherlands.
Silene diclinis is a dioecious perennial herb, restricted to a small area of the SE Spanish province of Valencia. Polyacrylamide gel electrophoresis and morphometric analysis were carried out on cultivated material derived from seed collected from the main population of S. diclinis at Játiva. Only two out of 26 inferred enzyme loci showed substantial variation. There was some indication of populat
Morphological and biochemical data were analysed from 30 greenhouse-grown populations of European Silene latifolia. Six separate character sets (flavones, seed, pollen, capsules, male and female flower morphology) were used in the analyses. There was broad-scale congruence between trends of geographic variation in most character sets, with the populations being assigned to western (or southern and
Three of the loci controlling isovitexin glycosylation in Silene pratensis are polymorphic and show geographic trends which are compared with geographic trends in seed morphology (and other phenotypic characters) as demonstrated by multivariate analysis. Various lines of evidence support the hypothesis that S. pratensis spread into Europe from at least two genetically differentiated sources. S. di
Relative a absolute (pollen concentration) diagrams are presented from Bergebyvatnet, Holmfjellvatnet and Stjernevatnet on Varanger peninsula. All three sites are outside the younger Dryas (Main substage) moraines and the pollen assemblage zones are correlated biostratigraphically with chronozones from Allerød to Middle Flandrian. Radiocarbon dates from Bergebyvatnet appear to have been affected b
A relative and absolute (pollen concentration) diagram is presented from Østervatnet, southern Varanger peninsula, north of the Main sub‐stage (Tromsø‐Lyngen) moraines. The pollen assemblage zones are correlated biostratigraphically with chronozones from Bølling to Middle Flandrian. Sediment analyses (loss on ignition and particle size) and implied sedimentation rates support this chronology. The
North Hoy is an area containing a remarkable diversity of vegetation in a small area. A phytosociological account of the hill vegetation of North Hoy is presented, making use of an ordination method to clarify the inter‐relationships of the moorland vegetation types, as well as traditional methods. It has proved very interesting to compare the vegetation with the account of Scottish Highland veget
The Protein Ensemble Database (PED) (https://proteinensemble.org), which holds structural ensembles of intrinsically disordered proteins (IDPs), has been significantly updated and upgraded since its last release in 2016. The new version, PED 4.0, has been completely redesigned and reimplemented with cutting-edge technology and now holds about six times more data (162 versus 24 entries and 242 vers
Background and Aims: It is unclear whether obesity is associated with the development of inflammatory bowel disease despite compelling data from basic science studies. We therefore examined the association between obesity and risk of Crohn's disease (CD) and ulcerative colitis (UC). Methods: We conducted pooled analyses of 5 prospective cohorts with validated anthropometric measurements for body m
Objectives: Clinical trials demonstrated that golimumab is effective in anti-TNF naïve patients with ulcerative colitis. We aimed to assess the clinical effectiveness of golimumab in a real-world setting. Materials and methods: This was a prospective cohort study, conducted at 16 Swedish hospitals. Data were collected using an electronic case report form. Patients with active ulcerative colitis, d
Forty-two years ago, Stephen Hawking made predictions that radiation does escape from black holes. Known as “Hawking radiation” this phenomenon is too weak to observe with current techniques, and remained the “Holy Grail” for astrophysics. It has remained as such until recently when researchers led by Professor Steinhauer at the Israel Institute of Technology observed radiation emanating from an a

BACKGROUND AND OBJECTIVES: Atrial fibrillation (AF) is associated with inflammation systemically and in the atrial tissue. Oxidized low-density lipoprotein (LDL) is increased in patients with AF and is suggested to be one of the molecules that drives inflammation. Autoantibodies against oxidized LDL and apolipoprotein B100, the protein component of LDL, are linked to atherosclerotic disease. Howev
OBJECTIVE Methylglyoxal (MGO), a reactive aldehyde forming advanced glycation end products (AGEs), is increased in diabetes and recognized by the immune system, resulting in anti-AGE-specific autoantibodies. The association of these immune responses with macro- and microvascular complications in type 1 diabetes remains unclarified. We investigated associations between MGO-modified apolipoprotein B
A Transverse Resonance Island Bucket optics has a betatron tune close to a resonance, such that the particle motion is governed by non-linear terms in the equation of motion. This results in additional stable fixed points in transverse phase-space, which can be populated with a single RF-bunch filling pattern. Thus, these optics have the potential of providing pseudo single-bunch operation, i.e. a
