Estudio previo a la implantación de un ERP en una empresa transitaria

Aquest projecte tracta de l'estudi previ que cal fer en una empresa abans d'aventurar-se a la implantació d'un sistema ERP. Ens centrarem en una PIME que té com a activitat bàsica la importació-exportació de mercaderies a o des de les Illes Canàries. L'estudi s'ha centrat en tres sistemes ERPs que es troben en el mercat actualment. La selecció té com a objetiu exposar els productes dels dos principals fabricants, SAP i Microsoft Navision. En contrapartida, ens ha semblat molt interessant incloure com a tercer sistema estudiat Open Bravo, un ERP basat en software lliure.

Mediterranean populations of the lesser white-toothed shrew (Crocidura suaveolens group): an unexpected puzzle of Pleistocene survivors and prehistoric introductions.

An earlier study revealed the strong phylogeographical structure of the lesser white-toothed shrew (Crocidura suaveolens group) within the northern Palaearctic. Here, we aim to reconstruct the colonization history of Mediterranean islands and to clarify the biogeography and phylogeographical relationships of the poorly documented Middle East region with the northern Palaearctic. We performed analyses on 998-bp-long haplotypes of the mitochondrial cytochrome b gene of 143 samples collected around the Mediterranean basin, including islands and the Middle East. The analyses suggest that the Cypriot shrew belongs to the rare group of relict insular Pleistocene mammal taxa that have survived to the present day. In contrast, the Cretan, Corsican and Menorcan populations were independently introduced from the Middle East during the Holocene. The phylogeographical structure of this temperate Palaearctic species within the Middle East appears to be complex and rich in diversity, probably reflecting fragmentation of the area by numerous mountain chains. Four deeply divergent clades of the C. suaveolens group occur in the area, meaning that a hypothetical contact zone remains to be located in central western Iran.

Neuroendocrine, metabolic, and immune functions during the acute phase response of inflammatory stress in monosodium L-glutamate-damaged, hyperadipose male rat.

In rats, neonatal treatment with monosodium L-glutamate (MSG) induces several metabolic and neuroendocrine abnormalities, which result in hyperadiposity. No data exist, however, regarding neuroendocrine, immune and metabolic responses to acute endotoxemia in the MSG-damaged rat. We studied the consequences of MSG treatment during the acute phase response of inflammatory stress. Neonatal male rats were treated with MSG or vehicle (controls, CTR) and studied at age 90 days. Pituitary, adrenal, adipo-insular axis, immune, metabolic and gonadal functions were explored before and up to 5 h after single sub-lethal i.p. injection of bacterial lipopolysaccharide (LPS; 150 microg/kg). Our results showed that, during the acute phase response of inflammatory stress in MSG rats: (1) the corticotrope-adrenal, leptin, insulin and triglyceride responses were higher than in CTR rats, (2) pro-inflammatory (TNFalpha) cytokine response was impaired and anti-inflammatory (IL-10) cytokine response was normal, and (3) changes in peripheral estradiol and testosterone levels after LPS varied as in CTR rats. These data indicate that metabolic and neroendocrine-immune functions are altered in MSG-damaged rats. Our study also suggests that the enhanced corticotrope-corticoadrenal activity in MSG animals could be responsible, at least in part, for the immune and metabolic derangements characterizing hypothalamic obesity.

Els isòtops radiogènics(Sr i Nd) en diferents contextes geodinàmics: Illes Canaries i Vesuvi. Preparació i anàlisi de mostres mitjançant la tècnica analítica TIMS

Projecte de recerca elaborat a partir d’una estada l’ Osservatorio Vesuviano (Nàpols, Italia) entre novembre del 2006 i març del 2007. Un dels objectius principals de l’estada ha estat conèixer la tècnica analítica Thermal Ionisation Mass Spectrometry (TIMS ) per l’anàlisi d’isòtops radiogènics (Sr i Nd). Aquesta estada ha permès aprendre tant la part de preparació de les mostres, com la part d’utilització i programació de l’instrument. Inicialment en el projecte es va programar l’anàlisi dels isòtops radiogènics en laves i xenòlits de l’illa de Gran Canaria (Illes Canàries) amb l’objectiu de modelar geoquímicament el mantell terrestre sota les illes Canàries. Finalment, i a part de les mostres inicials de Gran Canaria, es van incloure mostres del volcà Vesuvi per tal de concloure un projecte iniciat el 2003 amb el Professor Giovanni Orsi i la Professora Lucia Civetta. L’estudi dels isòtops radiogènics en contextes geodinàmics tant diferents ha permès comparar la variació dels isòtops radiogènics de Sr i Nd que existeix entre volcanisme d’ intraplaca (Illes Canàries) i volcanisme en zones convergents (Vesuvi).

Deteccion de amastigotas en Leishmaniasis cutanea y mucocutanea por el metodo de inmunoperoxidasa, usando anticuerpo policlonal: sensibilidad y especificidad comparadas con metodos convencionales de diagnostico

Con el objeto de aumentar la sensibilidad del diagnóstico histopatológico de lesiones cutáneas y mucocutáneas causada por subespecies del complejo Leismania braziliensis y para lograr una mejor visualización de los parásitos en las lesiones, se evaluó el método de la inmunoperoxidas indirecta para localizar en forma rápida y específica los amastigotas en biopsia de tejido afectado. Los cortes de tejido se fijaron en formol y se incluyeron en parafina; después se evaluaron por inmunohistoquímica usando un antisuero policlonal producido en conejo, como reactivo primario, Se examinaron 265 biopsias de pacientes con lesiones sospechosas de leishmaniasis de la costa Pacífica y región suroriental colombiana. a 1983 (72.8%) pacientes se les estableció el diagnóstico por métodos clínicos y/o poarasitológicos. Los resultados obtenidos por la inmunoperoxidasa en el grupo de pacientes a los cuales se les confirmó la leishmaniasis se compararn con la histopatología convencional, el examen directo de frotis y el aislamiento del parásito por cultivo del aspirado de la lesión. La localización inmunoenzimática de las amastigotas fue más efectivas (61.3%) que la histopatología com hematoxilina y eosina (34.6%), y que el frotis (43,9%). En cambio, el cultivo de aspirado fue más sensible (89.8%). La eficiencia del método de inmunoperoxidasa fue mayor en las lesiones recientes (72.5%) positivos en los casos con menos de tres meses de evolución) que en las lesiones más antiguas (55.6, 37.5 y 21.1% para 3-5.9, 6-11 meses y mayores o iguales a 12 mese, respectivamente). La combinación de frotis e inmunoperoxidasa incrementó el porcentaje de caso diagnosticados a 72.0%, lo que indica la importancia de combinar métodos para obtener una mayor eficiencia de diagnóstico. La especificidad fue de 100% en controles sanos y 92.9% en pacientes con lesiones causadas por agentes etiológicos distintos a leishmania.

Outcomes of disconnective surgery in intractable pediatric hemispheric and subhemispheric epilepsy.

Objectives: To study the outcome of disconnective epilepsy surgery for intractable hemispheric and sub-hemispheric pediatric epilepsy. Methods: A retrospective analysis of the epilepsy surgery database was done in all children (age <18 years) who underwent a peri-insular hemispherotomy (PIH) or a peri-insular posterior quadrantectomy (PIPQ) from April 2000 to March 2011. All patients underwent a detailed pre surgical evaluation. Seizure outcome was assessed by the Engel's classification and cognitive skills by appropriate measures of intelligence that were repeated annually. Results: There were 34 patients in all. Epilepsy was due to Rasmussen's encephalitis (RE), Infantile hemiplegia seizure syndrome (IHSS), Hemimegalencephaly (HM), Sturge Weber syndrome (SWS) and due to post encephalitic sequelae (PES). Twenty seven (79.4%) patients underwent PIH and seven (20.6%) underwent PIPQ. The mean follow up was 30.5 months. At the last follow up, 31 (91.1%) were seizure free. The age of seizure onset and etiology of the disease causing epilepsy were predictors of a Class I seizure outcome. Conclusions: There is an excellent seizure outcome following disconnective epilepsy surgery for intractable hemispheric and subhemispheric pediatric epilepsy. An older age of seizure onset, RE, SWS and PES were good predictors of a Class I seizure outcome.

Viral envelope glycoprotein processing by proprotein convertases.

The proprotein convertases (PCs) are a family of nine mammalian enzymes that play key roles in the maintenance of cell homeostasis by activating or inactivating proteins via limited proteolysis under temporal and spatial control. A wide range of pathogens, including major human pathogenic viruses can hijack cellular PCs for their own purposes. In particular, productive infection with many enveloped viruses critically depends on the processing of their fusion-active viral envelope glycoproteins by cellular PCs. Based on their crucial role in virus-host interaction, PCs can be important determinants for viral pathogenesis and represent promising targets of therapeutic antiviral intervention. In the present review we will cover basic aspects and recent developments of PC-mediated maturation of viral envelope glycoproteins of selected medically important viruses. The molecular mechanisms underlying the recognition of PCs by viral glycoproteins will be described, including recent findings demonstrating differential PC-recognition of viral and cellular substrates. We will further discuss a possible scenario how viruses during co-evolution with their hosts adapted their glycoproteins to modulate the activity of cellular PCs for their own benefit and discuss the consequences for virus-host interaction and pathogenesis. Particular attention will be given to past and current efforts to evaluate cellular PCs as targets for antiviral therapeutic intervention, with emphasis on emerging highly pathogenic viruses for which no efficacious drugs or vaccines are currently available.

El suro com a adsorbent del plom i el poloni

S’ha estudiat la utilització del suro com a adsorbent de metalls i radionúclids, com el plom i el poloni. Aquesta metodologia es pot aplicar en diferents camps, principalment per la separació d’aquests elements tant per a la seva posterior anàlisi com per l’eliminació i descontaminació en medis naturals. El suro és un bon adsorbent del plom, ja que de promig n’adsorbeix un 80%, i existeix dependència amb la relació superfície – volum del suro. La capacitat de càrrega màxima, a partir de les vuit hores, correspon al suro de diàmetre de partícula de 0.5 a 1 mm, amb un valor proper a 6·10-2 mmol Pb/g suro. El poloni presenta una eficiència d’adsorció menor a la del plom, d’un 50% del poloni present en la solució de càrrega inicial. Del present treball es pot concloure que el suro és un bon material adsorbent per a metalls i/o radionúclids, i per tan pot ser emprat com a una tècnica de separació i/o recuperació alternativa a les actualment establertes, sent més econòmica i biodegradable.

Aging and motor programming: differential effects according to the selection of action

There are controversial reports about the effect of aging on movement preparation, and it is unclear to which extent cognitive and/or motor related cerebral processes may be affected. This study examines the age effects on electro-cortical oscillatory patterns during various motor programming tasks, in order to assess potential differences according to the mode of action selection. Twenty elderly (EP, 60-84 years) and 20 young (YP, 20-29 years) participants with normal cognition underwent 3 pre-cued response tasks (S1-S2 paradigm). S1 carried either complete information on response side (Full; stimulus-driven motor preparation), no information (None; general motor alertness), or required free response side selection (Free; internally-driven motor preparation). Electroencephalogram (EEG) was recorded using 64 surface electrodes. Alpha (8-12 Hz) desynchronization (ERD)/synchronization (ERS) and motor-related amplitude asymmetries (MRAA) were analyzed during the S1-S2 interval. Reaction times (RTs) to S2 were slower in EP than YP, and in None than in the other 2 tasks. There was an Age x Task interaction due to increased RTs in Free compared to Full in EP only. Central bilateral and midline activation (alpha ERD) was smaller in EP than YP in None. In Full just before S2, readiness to move was reflected by posterior midline inhibition (alpha ERS) in both groups. In Free, such inhibition was present only in YP. Moreover, MRAA showed motor activity lateralization in both groups in Full, but only in YP in Free. The results indicate reduced recruitment of motor regions for motor alertness in the elderly. They further show less efficient cerebral processes subtending free selection of movement in elders, suggesting reduced capacity for internally-driven action with age.

Laurostrongylus hoineffae n. gen., n. sp., a relict trichostrongylid from an endemic madagascan rodent

A new nematode, the type of a new genus and a new species Laurostrongylus hoineffae, parasitic in the cricetid rodent Gymnuromys roberti in Madagascar, is described. The species belongs to the Graphiidinae subfamily of Trichostrongylidae but some features point to its affinity to certain Libyostrongylinae, especially to two monospecific genera endemic in Madagascar Pararhabdonema and Cnizostrongylus. This ensemble of relict species seems thus to support the concept of a common ancestor for the Libyostrongylinae and Graphidiinae. The two subfamilies were supposed to originate in the Ethipian region. The presence of the three generain Madagascar could either indicate their Madagascan origin or, more likely, a continental origin with an insular niche allowing the preservation of the species.
