Triteleia peyerimhofficomb. n. (Kieffer, 1906) is redescribed taking into account its great variability and is considered the senior synonym of Triteleia dubia (Kieffer, 1908), Calliscelio lugens (Kieffer, 1910) and Triteleia striolata Kononova & Petrov, 2000, syn. n. Neotypes are designated for Triteleia dubia and Triteleia peyerimhoffi. Triteleia peyerimhoffi is a new record for Greece, Franc...

Tubular and fibrillar forms of P protein (slime) have been reported in sieve elements of a wide range of higher vascular plants . However, all P protein components encountered in previous investigations have been extranuclear in their occurrence . At this time we are reporting on the presence of tubular and fibrillar forms of P protein in both nucleus and cytoplasm of differentiating sieve elem...

The paper uses the SCOP theory of concepts to model the role of environmental context on three levels of entrepreneurial opportunity: idea generation, idea development, and entrepreneurial decision. The role of contextual-fit in the generation and development of ideas is modeled as the collapse of their superposition state into one of the potential states that composes this superposition. The p...

The objectives of this study were to examine the foliar sensitivity to ozone exposure of 12 tree, shrub, and herbaceous species native to southern Switzerland and determine the seasonal cumulative ozone exposures required to induce visible foliar injury. The study was conducted from the beginning of May through the end of August during 2000 and 2001 using an open-top chamber research facility l...

A significant interaction between N-methyl-D-aspartate (NMDA) and muscarinic receptors has been suggested in the modulation of learning and memory processes. The present study further investigates this issue and explores whether d-cycloserine (DCS), a partial agonist at the glycine binding site of the NMDA receptors that has been regarded as a cognitive enhancer, would reverse scopolamine (SCOP...

An analysis was performed on 335 pairs of structurally aligned proteins derived from the structural classification of proteins (SCOP http://scop.mrc-lmb.cam.ac.uk/scop/) database. These similarities were divided into analogues, defined as proteins with similar three-dimensional structures (same SCOP fold classification) but generally with different functions and little evidence of a common ance...
