    Notes: Various model systems were designed in order to analyse the way in which addition of different levels of walnut (0, 10, 20%) and processing by high pressure (HPP) (400 MPa for 10 min at 10 °C) influenced the physico-chemical properties of cooked (70 °C for 30 min) meat batters. The addition of walnut increased the fat level and decreased the moisture content in the meat batters. All of the meat batters exhibited good water and fat binding properties. The hardness, cohesiveness, springiness and chewiness of cooked products were reduced by addition of walnut but were unaffected by HPP. Incorporation of nuts in meat products can potentially be used to confer cardiac health benefits.

    Notes: Haploid and amphihaploid Verticillium dahliae isolates were studied using PCR-based molecular markers which: (i) discriminate the defoliating and nondefoliating pathotypes (two primer pairs INTD2f/r and INTND2f/r), and (ii) are species-specific (primer pair 19/22). The results were compared with some known biological and other molecular properties of the isolates. Five discrete sequences of the 19/22 amplicon were found. Sequence 4 was associated with both defoliating isolates from Spain and nondefoliating isolates from Spain and USA; these pathotypes were separated by the primer pairs INTD2f/r and INTND2f/r, but the data showed that the primer espdef01 (derived from the 19/22 amplicon) cannot be used for this purpose. Amplicon sizes and sequences with primers 19/22 divided amphihaploid isolates from crucifers (thought to be interspecific hybrids) into those corresponding to the previously reported α and β groups. The β-group isolates had either sequence 4 or 5 (these two differing by a single base). The distinct amplicon sequence 3 given by the α-group isolates demonstrated that the V. dahliae-like ‘parent’ of this group was molecularly unlike any haploid isolate yet studied. The overall results are discussed in relation to phytosanitary considerations and the probability of defoliating or crucifer pathotypes arising de novo within Europe, either by selection or by interspecific hybridizations.

    Notes: Background:  The term ‘glomeruloid haemangioma’ was coined by Chan et al. for a histologically distinctive cutaneous haemangioma, which they considered a specific cutaneous marker for POEMS syndrome. Glomeruloid haemangiomas appear to be specific to POEMS syndrome, because they have not been reported in patients without this syndrome.Methods:  We report on an 86-year-old man without POEMS syndrome and with a solitary red papule on the face.Results:  A cutaneous biopsy showed histological findings consistent with a glomeruloid haemangioma. Physical examination of the skin did not show any other cutaneous lesion and laboratory and radiological studies ruled out the presence of POEMS syndrome.Conclusions:  Glomeruloid haemangiomas could exceptionally be present as solitary vascular tumours and out of the context of POEMS syndrome. To our knowledge, this is the first case reported of glomeruloid haemangioma without POEMS syndrome. Moreover, the presentation on the face is also highly unusual.

    Notes: Abstract:  Mitochondrial dysfunction might play a role in the pathogenesis of liver damage in erythropoietic protoporphyria (EPP). Changes in mitochondrial respiratory chain activities were evaluated in the Fechm1pas/Fechm1pas mouse model for EPP.Mice from different strains congenic for the same ferrochelatase germline mutation manifest variable degrees of hepatobiliary injury. Protoporphyric animals bred into the C57BL/6J background showed a higher degree of hepatomegaly and liver damage as well as higher protoporphyrin (PP) accumulation than those bred into the SJL/J and BALB/cJ backgrounds. Whereas mitochondrial respiratory chain activities remained unchanged in the liver of protoporphyric mice C57BL/6J, they were increased in protoporphyric mice from both SJL/J and BALB/cJ backgrounds, when compared to wild-type animals. Mitochondrial respiratory chain activities were increased in Hep G2 cell line after accumulation of PP following addition of aminolevulinic acid. As a direct effect of these elevated mitochondrial activities, in both hepatic cells from mutant mouse strains and Hep G2 cells, adenosine 5′-triphosphate (ATP) levels significantly increased as the intracellular PP concentration was reduced.These results indicate that PP modifies intracellular ATP requirements as well as hepatic mitochondrial respiratory chain enzymatic activities and further suggest that an increase of these activities may provide a certain degree of protection against liver damage in protoporphyric mice.

    Notes: The main objective of this work is to develop conductive yarns to be used as electricalwiring in e-textiles with the typical mechanical properties of a textile yarn. Present workdeals with the study of conductive polymer composites filaments of PP (polypropylene)with CB (carbon black), carbon black of high conductivity (CBHC) and CF (carbonfibers) .The novelty of this work resides in creating oriented filaments using traditionalfiber processing techniques together with a specially designed drafting machine. In theauthors’ opinion, the composite conductivity could be improved with the orientation ofthe (nano)carbon-based fillers by melt drawing after extrusion in order to facilitate theflow channels creation

    Notes: Purpose - Aims to contribute to the teleworking literature by analysing the differences between teleworking adopters and non-adopters regarding the use and impact of information and communication technologies. Design/methodology/aproach - Analyses the differences on the use and impact of information and communication technologies in a sample of Spanish companies. The data for the study come from a survey of a representative sample of 479 small and medium sized companies located in Galicia, a Spanish region in the northwest of the country. The data were obtained through interviews with the company managers (CEO, systems information manager, or technology manager) between May and October of 2003 Findings - The results indicate that teleworking companies have adopted more equipment (per company and per employee), and the differences are statistically significant for all type of information equipment but personal computers. Although there is a positive correlation between the number of equipment and firm size (number of employees), there are not statistically significant differences of firm size between teleworking adopters and non adopters. Firm size is not an explanatory variable of equipment use in the adopter companies. Originality/value - Contributes to the teleworking literature by analysing the differences between teleworking adopters and non adopters regarding the use and impact of information and communication technologies

    Notes: By means of reverse transcriptase-polymerase chain reaction, using degenerate oligonucleotides conserved among ethylene-responsive transcription factors, we have isolated and characterized a cDNA clone encoding a protein involved in ethylene signalling during the breaking of dormancy in Fagus sylvatica L. seeds. This clone, named FsERF1, exhibits high homology to ethylene-responsive factors (ERFs) from several plant species. The expression of FsERF1 as a fusion protein in Escherichia coli confirmed that it was able to bind to the GCC box, a cis element present in the promoters of several ethylene-responsive genes, corroborating its role as a DNA-binding protein. Northern analysis showed that the transcript levels increased when dormancy was broken by ethephon (an ethylene-releasing compound), or by moist prechilling pretreatment at restricted water content, and were almost undetectable when seeds remained dormant by the addition of abscisic acid, aminooxyacetic acid (an ethylene biosynthesis inhibitor) or warm pretreatment, and when seeds were artificially dried, suggesting that FsERF1 function may be more closely related with the transition from seed dormancy to germination than with responses to drought stress mediated by ethylene.
