pre/parats?

El treball que teniu a les mans és la memòria del projecte de final de grau, el documental Pre/parats?. Aquestes pàgines contenen la feina de nou mesos que va resultar en un documental que investiga la realitat dels joves universitaris dins del marc socioeconòmic actual. Pre/parats? és el títol que dóna nom a aquest documental. La nostra intenció era jugar amb el doble sentit de les paraules per a referir-nos a la situació postuniversitària. Així doncs, plantegem si estem preparats per afrontar el món laboral o si, per contra, som els pròxims a la cua de l’atur. El treball està dividit en funció de les fases que es duen a terme a l’hora de realitzar una peça audiovisual: començant per la primera fase, la presa de decisions; passant també per la resta de fases, com són el desenvolupament del guió, la preproducció, el rodatge, el muntatge i la postproducció; i acabant per la distribució del producte. Per últim, hi ha les conclusions finals de cada un dels membres del grup i les conclusions generals del projecte.

Cooperating pre-T-cell receptor and TCF-1-dependent signals ensure thymocyte survival.

Intrathymic T-cell maturation critically depends on the selective expansion of thymocytes expressing a functionally rearranged T-cell receptor (TCR) beta chain. In addition, TCR-independent signals also contribute to normal T-cell development. It is unclear whether and how signals from the 2 types of pathways are integrated. Here, we show that T-cell factor-1 (TCF-1), a nuclear effector of the canonical wingless/int (wnt)/catenin signaling pathway, ensures the survival of proliferating, pre-TCR(+) thymocytes. The survival of pre-TCR(+) thymocytes requires the presence of the N-terminal catenin-binding domain in TCF-1. This domain can bind the transcriptional coactivator beta-catenin and may also bind gamma-catenin (plakoglobin). However, in the absence of gamma-catenin, T-cell development is normal, supporting a role for beta-catenin. Signaling competent beta-catenin is present prior to and thus arises independently from pre-TCR signaling and does not substantially increase on pre-TCR signaling. In contrast, pre-TCR signaling significantly induces TCF-1 expression. This coincides with the activation of a wnt/catenin/TCF reporter transgene in vivo. Collectively, these data suggest that efficient TCF-dependent transcription requires that pre-TCR signaling induces TCF-1 expression, whereas wnt signals may provide the coactivator such as beta-catenin. The 2 pathways thus have to cooperate to ensure thymocyte survival at the pre-TCR stage.

Automatic Recognition of Leaves by Shape Detection Pre-Processing with Ica

In this work we present a simulation of a recognition process with perimeter characterization of a simple plant leaves as a unique discriminating parameter. Data coding allowing for independence of leaves size and orientation may penalize performance recognition for some varieties. Border description sequences are then used to characterize the leaves. Independent Component Analysis (ICA) is then applied in order to study which is the best number of components to be considered for the classification task, implemented by means of an Artificial Neural Network (ANN). Obtained results with ICA as a pre-processing tool are satisfactory, and compared with some references our system improves the recognition success up to 80.8% depending on the number of considered independent components.

Is a pre-anaesthetic information form really useful?

BackgroundAll patients should be fully informed about the risks and benefits of anaesthetic procedures before giving a written consent. Moreover, the satisfaction level may vary in proportion to the information given. We aimed to determine, in a single-blind randomized-controlled study, whether an information form given before the pre-anaesthetic consultation could improve perceived information, information gain and satisfaction level.MethodsTwo hundred patients ASA 1-3 scheduled for an elective orthopaedic surgery were randomized into two groups: a group that received an information form before the pre-anaesthetic consultation (IF group) and a control group (no information form). A standardized questionnaire was submitted after the pre-anaesthetic consultation and after the operation. This 17-item questionnaire explored perceived information (five items), information gain (three items) and satisfaction level (nine items). The items of each topic were pooled and compared between groups.ResultsOne hundred and eighty-five patients (92.5%) completed the study. The IF group had better perceived information (IF group 73% vs. control group 63%, P=0.002), higher information gain (IF group 75% vs. control group 62%, P=0.001) and a higher satisfaction level (IF group 95% vs. control group 92%, P=0.048).ConclusionsOur study suggests that an information form given before the pre-anaesthetic consultation enhances perceived information, information gain and satisfaction level.

KIR-associated protection from CMV replication requires pre-existing immunity: a prospective study in solid organ transplant recipients.

Previous studies have associated activating Killer cell Immunoglobulin-like Receptor (KIR) genes with protection from cytomegalovirus (CMV) replication after organ transplantation. Whether KIR-associated protection is operating in the context of primary infection, re-activation, or both, remains unknown. Here we correlated KIR genotype and CMV serostatus at the time of transplantation with rates of CMV viremia in 517 heart (n=57), kidney (n=223), liver (n=165) or lung (n=72) allograft recipients reported to the Swiss Transplant Cohort Study. Across the entire cohort we found B haplotypes-which in contrast to A haplotypes may contain multiple activating KIR genes-to be protective in the most immunosuppressed patients (receiving anti-thymocyte globulin induction and intensive maintenance immunosuppression) (hazard ratio after adjustment for covariates 0.46, 95% confidence interval 0.29-0.75, P=0.002). Notably, a significant protection was detected only in recipients who were CMV-seropositive at the time of transplantation (HR 0.45, 95% CI 0.26-0.77, P=0.004), but not in CMV seronegative recipients (HR 0.59, 95% CI 0.22-1.53, P=0.28). These data indicate a prominent role for KIR-and presumably natural killer (NK) cells-in the control of CMV replication in CMV seropositive organ transplant recipients treated with intense immunosuppression.
