Prunus necrotic ringspot ilarvirus (PNRSV) exists as a number of biologically distinct variants which differ in host specificity, serology, and pathology. Previous nucleotide sequence alignment and phylogenetic analysis of cloned reverse transcription-polymerase chain reaction (RT-PCR) products of several biologically distinct sweet cherry isolates revealed(More)
Sulfur is required for the biosynthesis of cysteine, methionine and numerous other metabolites, and thus is critical for cellular metabolism and various growth and developmental processes. Plants are able to sense their physiological state with respect to sulfur availability, but the sensor remains to be identified. Here we report the isolation and(More)
BACKGROUND Magnetic resonance cholangiography is a new technique which has already gained a role in primary sclerosing cholangitis. Computerised tomographic cholangiography is another non-invasive technique which has been used in assessing abnormal biliary tree, but has never been applied to evaluating primary sclerosing cholangitis. AIMS To evaluate the(More)
The toxicity of azetidine-2-carboxylic acid (A2C), a structural analogue of L-proline, results from its incorporation into proteins due to misrecognition by prolyl-tRNA synthetase (ProRS). The growth of Arabidopsis thaliana seedling roots is more sensitive to inhibition by A2C than is cotyledon growth. Arabidopsis contains two ProRS isozymes. AtProRS-Org(More)
Exposure to xylene in a pathology laboratory was evaluated using two algorithms: Stoffenmanager and Archi.me.de. The results were compared with those obtained by applying the environmental and biological monitoring of the exposure. The use of models required a period of self-learning and, for Stoffenmanager, knowledge of the English language. Information on(More)
The efficiency of the honeycomb selection procedure in selecting outstanding genotypes was observed at two interplant distances (d), i.e. d=100 cm, low density, representing noncompetitive conditions and d=15 cm, high density, representing presence of interplant competition. Progress due to selection among the plants grown with and without competition was(More)
The plasma levels of soluble thrombomodulin (TM) were measured in 44 patients with chronic myeloproliferative disorder, 15 with polycythemia vera (PV), 29 with essential thrombocythemia (ET), and a group of 62 matched healthy controls. The younger patients had significantly lower TM levels (mean: 15.6 +/- 4.8 ng/mL) than the older patients (mean: 28.6 +/-(More)
For a second consecutive generation, the efficiency of the honeycomb selection procedure was observed at low and at high density, i.e. interplant distance being 100 cm and 15 cm respectively. Progress due to selection was determined for each of the two plant densities applied by comparing the performance of offspring from selected plants with that of(More)
The paper focuses on a Italian project funded by the European Commission with the objective of improving the capacity of archiving, cataloguing and accessing the cultural heritage represented by business historical archives. The approach identified is to enhance the level of description (semantics) of the data to develop strategies for digital cultural(More)
