Motivation controls behavior [1]. A variety of food-related behaviors undergo motivational modulation by hunger, satiety, and other states [2-4]. Here we searched for critical satiation factors modulating approach to an odor associated with sugar reward in Drosophila melanogaster. We selectively manipulated different parameters associated with feeding, such(More)
BACKGROUND The conserved Fat and Core planar cell polarity (PCP) pathways work together to specify tissue-wide orientation of hairs and ridges in the Drosophila wing. Their components form intracellularly polarized complexes at adherens junctions that couple the polarity of adjacent cells and form global patterns. How Fat and Core PCP systems interact is(More)
BACKGROUND Previous studies have suggested that desmoteplase, a novel plasminogen activator, has clinical benefit when given 3-9 h after the onset of the symptoms of stroke in patients with presumptive tissue at risk that is identified by magnetic resonance perfusion imaging (PI) and diffusion-weighted imaging (DWI). METHODS In this randomised,(More)
A real-time PCR method was developed to quantitate viral DNA that includes duplex amplification, internal standardization, and two-color fluorescence detection without the need to generate an external standardization curve. Applied to human parvovirus B19 DNA, the linear range was from 10(2) to at least 5 x 10(6) copies per ml of sample. The coefficient of(More)
BACKGROUND AND PURPOSE We report the first case of 2 intravenous thrombolysis treatments within 90 hours in a patient with early recurrent stroke. SUMMARY OF REVIEW A 50-year-old man had improved significantly after intravenous thrombolysis for acute stroke. On the fourth day, he deteriorated dramatically because of recurrent stroke. Evidence of vessel(More)
BACKGROUND AND PURPOSE In a very limited number of cases, acute migrainous aura may mimic acute brain infarction. The aim of this study was to recognize patterns of MR perfusion abnormalities in this presentation. MATERIALS AND METHODS One thousand eight hundred fifty MR imaging studies performed for the suspicion of acute brain infarction were analyzed(More)
Hallux valgus represents a combined deformity with malpositioning of the big toe in the metatarsophalangeal joint and metatarsal splaying due to metatarsus primus varus formation. It is defined on the basis of joint condition of the metatarsophalangeal and tarsometatarsal (TMT) joints, the extent and congruence or incongruence of malposition, mobility of(More)
Teil 1: Magnetism and minimal surfaces-A different tool for surface design/ Teil 1: Magnetism and minimal surfaces-A different tool for surface design Abstract The design of free form surfaces is usually based on NURBS and it works well to quickly get shapes that a designer intends to create. Such surfaces then have desired properties like given border(More)
BACKGROUND Various techniques have been developed to estimate spontaneous baroreflex sensitivity noninvasively. However, in the EuroBaVar study it has been shown that they yield differing results. AIM OF THE STUDY To investigate the reliability of these methods further we compared the results of the most common sequence techniques. We used the paradigm of(More)
We systematically compare filtering methods used to extract topological excitations from lattice gauge configurations. We show that there is a strong correlation of the topological charge densities obtained by APE and Stout smearing. Furthermore, a first quantitative analysis of quenched and dynamical configurations reveals a crucial difference of their(More)
