Earlier detailed studies of cnidarian planula larvae have revealed a simple nervous system but no eyes or identifiable light sensing structures. Here, we describe the planula of a box jellyfish, Tripedalia cystophora, and report that these larvae have an extremely simple organization with no nervous system at all. Their only advanced feature is the presence of 10-15 pigment-cup ocelli, evenly spac

We have predicted that in suitable multiple barrier structures without applied bias, the thermopower may change sign because of quantum transport process. We have performed detailed numerical calculation to show that the predicted thermopower anomaly can be experimentally observed. This thermopower anomaly does not violate thermodynamic laws.
In our previous genome-wide scan of Finnish nuclear families, obesity was linked to chromosome Xq24. Here we analyzed this 15-Mb region by genotyping 9 microsatellite markers and 36 single nucleotide polyp morphisms (SNPs) for 11 positional and functional candidate genes in an extended sample of 218 obese Finnish sibling pairs (sibpairs) (BMI > 30 kg/m(2)). Evidence of linkage emerged mainly from
The life histories of holo-anhydrobiotic animals differ from those of all other organisms by a regular or irregular entrance into an ametabolic state induced by desiccation. Such ametabolic periods will arrest growth and reproduction completely and thus affect primary life history parameters dramatically. The selective forces and the genetic and physiological trade-offs acting on anhydrobiotic ani
In this paper some integral formulas for the fatigue damage in variable amplitude loading are presented. The formulas, which in their original form appeared in Rychlik (1993), may be used for both the theoretical analysis of the fatigue damage, resulting from different cycle counting algorithms, as well as for the computation of different statistical properties of the fatigue damage.
Genetic variants in the gene encoding for transcription factor-7-like 2 (TCF7L2) have been associated with type 2 diabetes (T2D) and impaired beta cell function, but the mechanisms have remained unknown. We therefore studied prospectively the ability of common variants in TCF7L2 to predict future T2D and explored the mechanisms by which they would do this. Scandinavian subjects followed for up to

We demonstrate how to generalize two of the most well-known random graph models, the classic random graph, and random graphs with a given degree distribution, by the introduction of hidden variables in the form of extra degrees of freedom, color, applied to vertices or stubs (half-edges). The color is assumed unobservable, but is allowed to affect edge probabilities. This serves as a convenient me
To fully support refactorings in a team development environment we have implemented a refactoring-aware repository provider as an extension plug-in to the Java Development Tools in Eclipse. The versioning system treats refactorings as first-class changes described as semantic ac- tions rather than the set of resulting changes scattered over the source tree. We also introduce refactoring-aware merg
n this study we use the N-substituted benzamides declopramide (3-CPA) and N-acetyl declopramide (Na-3-CPA) to investigate the involvement of the transcription factor NF-κB in the induction of apoptosis and surface immunoglobulin κ (Igκ) expression in the mouse pre-B cell line 70Z/3. We first showed that 3-CPA-induced apoptosis at doses around 500 μM and that the 3-CPA-induced apoptosis could be su
Seven novel diterpenoids, named heptemerones A-G, were isolated from the broth of submerged cultures of Coprinus heptemerus, a basidiomycete which previously had not been known to produce secondary metabolites. The compounds were purified by solid phase extraction and silica gel chromatography followed by preparative HPLC. Among the biological activities the inhibition of fungal germination was th
