[EN]Hyperventilation, which is common both in-hospital and out-of-hospital cardiac arrest, decreases coronary and cerebral perfusion contributing to poorer survival rates in both animals and humans. Current resucitation guidelines recommend continuous monitoring of exhaled carbon dioxide (CO2) during cardiopulmonary resucitation (CPR) and emphasize good quality of CPR, including ventilations at 8-10 min1. Most of commercial monitors/de- brilators incorporate methods to compute the respiratory rate based on capnography since it shows uctuations caused by ventilations. Chest compressions may induce artifacts in this signal making the calculation of the respiratory rate di cult. Nevertheless, the accuracy of these methods during CPR has not been documented yet. The aim of this project is to analyze whether the capnogram is reliable to compute ventilation rate during CPR. A total of 91 episodes, 63 out-of-hospital cardiac arrest episodes ( rst database) and 28 in-hospital cardiac arrest episodes (second database) were used to develop an algorithm to detect ventilations in the capnogram, and the nal aim is to provide an accurate ventilation rate for feedback purposes during CPR. Two graphic user interfaces were developed to make the analysis easier and another two were adapted to carry out this project. The use of this interfaces facilitates the managment of the databases and the calculation of the algorithm accuracy. In the rst database, as gold standard every ventilation was marked by visual inspection of both the impedance, which shows uctuations with every ventilation, and the capnography signal. In the second database, volume of the respiratory ow signal was used as gold standard to mark ventilation instants since it is not a ected by chest compressions. The capnogram was preprocessed to remove high frequency noise, and the rst di erence was computed to de ne the onset of inspiration and expiration. Then, morphological features were extracted and a decission algorithm built based on the extracted features to detect ventilation instants. Finally, ventilation rate was calculated using the detected instants of ventilation. According to the results obtained in this project, the capnogram can be reliably used to give feedback ventilation rate, and therefore, on hyperventilation in a resucitation scenario.

Azken hiru hamarkadetan, Euskal Autonomia-Erkidegoan aldaketa garrantzitsua eman da HPB (heziketa premia bereziak) duten ikasleei ematen zaien heziketa-erantzunean, laguntzaren behar orokor eta iraunkorrak aurkezten dituenari dagokionez bereziki. Gaur egun, ikasle hauek, LH eta DBH zentro arruntetan kokatutako gela egonkorretara joan daitezke. Gela hauetako curriculuma zabala eta malgua da eta ez dago era arauemailean Hezkuntza Sailagatik araututa. Gela horietan matrikulatutako ezgaitasuna duten ikasleek, eskola-ordutegi barruan, gorputz-hezkuntzako jarduerak egiteko eskubidea dute, bere etapako beste kideek bezala. Ikasle hauekin bultzatzen diren jarduera fisikoek bere bizi-kalitatea eta komunitatean bere inklusioa hobetzera orientatuta egon behar dute. Beraz, egokia izango litzateke zentro honen H.F. ikasleak jarduera horiek talde horrekin egiteko denbora espezifikoa bere ordutegian kontuan izan zezan . Ikasle horiek zentroaren bizitzan parte hartzeaz gain, institutuko irakasleek parte hartu behar dute mutil horien jardueretan. Inklusioak bere gain hartu behar ditu heziketa komunitatearen kide guztiak. GrAL honetan proposatzen eta justifikatzen da GH irakasleak irakasten duen kirola igeriketa izan dadila, ikasle hauen ezaugarriak kontutan hartuta eta fisiko, psikiko eta sozial mailan eragiten dituen onurengatik. Erabilitako metodoa analisi orokorrekotik kasu zehatz baten praktikara joatea izan da.

High-quality 2at%-doped Yb:CaF2 and Yb,Na:CaF2 single crystals with diameter of 76mm were grown by the temperature gradient technique. For the first time, distribution coefficients (KO) of Yb in the two crystals were determined to be 1.07 and 0.91, respectively, by measuring the Yb concentrations at the growth starting position in the as-grown boules. Absorption and emission spectra of the two different crystals were measured at room temperature. Experimental results show that Na+ ions codoping with Yb3+ as charge compensators make Yb3+ ions in CaF2 lattice to be a quasi-single-center system, and greatly suppress the deoxidization of Yb3+ to Yb2+ (c) 2005 Elsevier B.V.

[EUS] Gaur egun mundu osoa 2007ko banku krisian murgilduta dabil. Krisiaren sorrera hainbat ikuspuntutik azaldua izan da azken urteotan. Bankuen gobernantzaren eragina 2007ko banku krisian: basileako printzipioak eta adituen iritziak oinarri lanak, 2007-ko krisia banku gobernantzak izandako akatsetatik aztertu egiten du. Horretarako, arriskuaren kudeaketan, ordainsari sistemetan edota kontseiluetan krisi aurreko urteetan egondako gertaerak aztertuko dira. Aipatutako azterketa, Basileako printzipioetan eta bai aditu ezberdinen iritsietan oinarriturik egongo da. Hori dela eta, krisi aurretiko garaian indarrean zeuden Basilea I eta Basilea II azalduko dira lehenik eta behin. 2007ko Krisia eta baita banku gobernantzak bertan izandako akatsak aztertuko diren hurrengo esparruak dira. Banku gobernantzaren akatsen artean, arriskuaren kudeaketa, produktu finantzario berriak, ordainsari edo pizgarri sistemak eta kontseilua azalduko dira batez ere, hauek izan baitziren akats larrienak izan zutenak. Behin krisia eta haren faktoreak azalduta, Basilea III azalduko da krisi aurreko printzipioak (Basilea I eta Basilea II) krisi ondoren zelan aldatu diren ikusteko. Azkenik adituek banku gobernantza zelan hobetuko luketeen azalduko da eta gainera, aditu hauen iritsien eta basileako printzipioen aldaketen arteko konparaketa bat egingo da komunean zein ondoriotara hel daitekeen aztertzeko. Banku gobernantzaren akatsak aztertzeaz aparte, adituen ustez banku gobernantza nola hobe daitekeen ere aztertu egingo da arazoari irtenbideak bilatzeko asmoz. Krisiak Basileako printzipioetan eragindako aldaketak ere azalduko dira, banku gobernantzaren arauak zelan aldatu diren ikusteko. Beraz, banku gobernantzak izandako akatsak aztertuko dira. Akats guzti horiek etika aldetik zein eragin izan duten eta batez ere krisialdiaren hasieran izan zuten papera zein izan zen aztertuko da.

Background & Aims: Pro-inflammatory cytokines are important for liver regeneration after partial hepatectomy (PH). Expression of Fibroblast growth factor-inducible 14 (Fn14), the receptor for TNF-like weak inducer of apoptosis (TWEAK), is induced rapidly after PH and remains elevated throughout the period of peak hepatocyte replication. The role of Fn14 in post-PH liver regeneration is uncertain because Fn14 is expressed by liver progenitors and TWEAK-Fn14 interactions stimulate progenitor growth, but replication of mature hepatocytes is thought to drive liver regeneration after PH. Methods: To clarify the role of TWEAK-Fn14 after PH, we compared post-PH regenerative responses in wild type (WT) mice, Fn14 knockout (KO) mice, TWEAK KO mice, and WT mice treated with anti-TWEAK antibodies. Results: In WT mice, rare Fn14(+) cells localized with other progenitor markers in peri-portal areas before PH. PH rapidly increased proliferation of Fn14(+) cells; hepatocytic cells that expressed Fn14 and other progenitor markers, such as Lgr5, progressively accumulated from 12-8 h post-PH and then declined to baseline by 96 h. When TWEAK/Fn14 signaling was disrupted, progenitor accumulation, induction of pro-regenerative cytokines, hepatocyte and cholangiocyte proliferation, and over-all survival were inhibited, while post-PH liver damage and bilirubin levels were increased. TWEAK stimulated proliferation and increased Lgr5 expression in cultured liver progenitors, but had no effect on either parameter in cultured primary hepatocytes. Conclusions: TWEAK-FN14 signaling is necessary for the healthy adult liver to regenerate normally after acute partial hepatectomy.
