Una empresa ens contracta ja que té la necessitat de controlar la gestió del manteniment de tots els aparells que té instal·lats en els 32 centres de treball de que disposa (com poden ser extintors, calderes, aire condicionat, fotocopiadores, escàners, impressores, plotters, etc.), i el manteniment el porten a terme diferents empreses de serveis especialitzades. Aquesta gestió i l'accés a tota la informació necessària es realitzarà mitjançant procediments de Base de Dades.La Base de Dades que es crearà ha de ser capaç de portar a terme la gestió de manteniment de tot el maquinari existent en cadascun dels centres de l'empresa, i ha de disposar d'eines que permetin, per una banda, tractar correctament la informació referent als diferents tipus de manteniment (preventiu, correctiu, adaptatiu) que es pot aplicar als diferents equips, i per l'altra, que li permetin incorporar a la Base de Dades aquelles necessites futures, és a dir, que li permetin ser escalable.Aquesta Base de Dades també disposarà de mecanismes que li permetin tractar possibles problemes d'integració amb la resta del sistema, com per exemple, la creació d'un log de les diferents accions fetes amb la Base de Dades, o diferents mecanismes per fer diversos tests de les funcionalitats del sistema.A part de la gestió de manteniment, es disposarà també un magatzem de dades (DataWarehouse) per tal de poder analitzar la informació que conté la Base de Dades anteriorment esmentada, amb l'objectiu d'ajudar a prendre decisions sobre les dades existents en un moment donat.El projecte està dividit en dos blocs principals, on el primer es dissenyarà i s'implementarà una Base de Dades relacional, amb la seva definició de requeriments, l'anàlisi i disseny, desenvolupament de procediments de base de dades i proves per testejar el correcte funcionament, mentre que el segon es dissenyarà i s'implementarà un magatzem de dades (DataWarehouse) per explotar les dades existents en la base de dades relacional.

During the replication cycle of vaccinia virus, four different forms of viral particles are produced. The two extracellular enveloped forms, cell-associated enveloped virus and extracellular enveloped virus, are responsible for cell-to-cell transmission and long-range spread of infection both in vivo and in vitro. Despite the biological importance of the enveloped forms, the mechanism of envelopment and the components involved in this process have been analysed only recently. Therefore the individual steps and the rate-limiting factors of the envelopment process are still unknown. The protein p37K, an unglycosylated but acylated envelope protein of molecular mass 37 kDa, has been shown to be essential for envelopment. However, this study shows that over-expression of p37K by vaccinia virus recombinants reduces rather than increases the yield of infectious enveloped virus which is mainly due to the enveloped virions exhibiting a strongly diminished specific infectivity.

To gain insight into the function and regulation of malonyl-CoA decarboxylase (MCD) we have cloned rat MCD cDNA from a differentiated insulin-secreting pancreatic beta-cell-line cDNA library. The full-length cDNA sequence shows 69% identity with the cDNA cloned previously from the goose uropygial gland, and predicts a 492 amino acid protein of 54.7 kDa. The open reading frame contains an N-terminal mitochondrial targeting sequence and the C-terminal part of the enzyme ends with a peroxisomal (Ser-Lys-Leu) targeting motif. Since the sequence does not reveal hydrophobic domains, MCD is most likely expressed in the mitochondrial matrix and inside the peroxisomes. A second methionine residue, located 3' of the mitochondrial presequence, might be the first amino acid of a putative cytosolic MCD, since the nucleotide sequence around it fits fairly well with a consensus Kozak site for translation initiation. However, primer extension detects the presence of only one transcript initiating upstream of the first ATG, indicating that the major, if not exclusive, transcript expressed in the pancreatic beta-cell encodes MCD with its mitochondrial presequence. The sequence also shows multiple possible sites of phosphorylation by casein kinase II and protein kinase C. mRNA tissue-distribution analysis indicates a transcript of 2.2 kb, and that the MCD gene is expressed over a wide range of rat tissues. The distribution of the enzyme shows a broad range of activities from very low in the brain to elevated in the liver and heart. The results provide the foundations for further studies of the role of MCD in lipid metabolism and metabolic signalling in various tissues.

The aim of this study was to evaluate the indirect immunoperoxidase virus neutralization (IPVN) and mouse neutralization test (MNT) to detect antibodies against rabies virus from vaccinated dogs and cattle. The IPVN was set up for the ability to measure 0.5 International Units/ml (IU) of antibody required by the World Health Organization and the Office International des Epizooties as the minimum response for proof of rabies immunization. IPVN was developed and standardized in chicken embryo related (CER) cell line when 141 dog and 110 cattle sera were applied by serial five-fold dilutions (1:5, 1:25, 1:125) as well as the positive and negative reference controls, all added in four adjacent wells, of 96-well microplates. A 50 µl amount of CVS32 strain dilution containing 50-200 TCID50/ml was mixed to each serum dilution, and after 90 min 50 µl of 3 x 10(5) cells/mlcell suspension added to each well. After five days of incubation, the monolayers were fixed and the IPVN test performed. The correlation coefficient between the MNT and IPVN performed in CER cells was r = 0.9949 for dog sera (n = 100) and r = 0.9307 for cattle sera (n = 99), as well as good specificity (94.7%), sensitivity (87.5%), and agreement (96.6%) were also obtained. IPVN technique can adequately identify vaccinated and unvaccinated animals, even from low-responding vaccinated animals, with the advantage of low cost and faster then MNT standard test.

HIV-1 infects CD4+ T cells and completes its replication cycle in approximately 24 hours. We employed repeated measurements in a standardized cell system and rigorous mathematical modeling to characterize the emergence of the viral replication intermediates and their impact on the cellular transcriptional response with high temporal resolution. We observed 7,991 (73%) of the 10,958 expressed genes to be modulated in concordance with key steps of viral replication. Fifty-two percent of the overall variability in the host transcriptome was explained by linear regression on the viral life cycle. This profound perturbation of cellular physiology was investigated in the light of several regulatory mechanisms, including transcription factors, miRNAs, host-pathogen interaction, and proviral integration. Key features were validated in primary CD4+ T cells, and with viral constructs using alternative entry strategies. We propose a model of early massive cellular shutdown and progressive upregulation of the cellular machinery to complete the viral life cycle.

The expression of a hybrid gene formed by the promoter region of the Xenopus laevis vitellogenin gene B1 and the CAT coding region is regulated by estrogen when the gene is transfected into hormone-responsive MCF-7 cells. Furthermore, the 5' flanking region of the gene B1 alone can confer inducibility to heterologous promoters, although to a varying extent depending on the promoter used. Deletion mapping of he vitellogenin hormone-responsive sequences revealed that a 13 bp element 5'-AGTCACTGTGACC-3' at position -334 is essential for estrogen inducibility. We have shown previously that this 13 bp element is present upstream of several liver-specific estrogen-inducible genes.
