An analysis of inflation rates in the European Union using wavelets : strong evidence against unit roots

In this paper we assume inflation rates in European Union countries may in fact be fractionally integrated. Given this assumption, we obtain estimations of the order of integration by means a method based on wavelets coefficients. Finally, results obtained allow reject the unit root hypothesis on inflation rates. It means that a random shock on the rate of inflation in these countries has transitory effects that gradually diminish with the passage of time, that this, said shock hasn¿t a permanent effect on future values of inflation rates

Pharmaceutical care in an inpatient pediatric intensive care unit: an international multicentric study

Introduction Pediatric intensive care patient represent a population athigh risk for drug-related problems. Our objective is to describe drugrelated problems and intervention of four decentralized pharmacists inpediatric and cardiac intensive care unit.Materials & Methods Multicentric, descriptive and prospectivestudy over a six-month period (August 1st 2009-January 31st 2010).Drug-related problems and clinical interventions were compiled infour pediatric centers using a tool developed by the Socie´te´ Franc¸aisede Pharmacie Clinique. Data concerning patients, drugs, intervention,documentation, approval (if needed), and estimated impact werecompiled. The four pharmacists participating were from Belgium (B),France (F), Quebec (Q) and Switzerland (S).Results A total of 996 interventions were collected: 129 (13%) in B,238 (24%) in F, 278 (28%) in Q and 351 (35%) in S. These interventionstargeted 269 patients (median 22 month-old, 52% male): 69(26%) in B, 88 (33%) in F, 56 (21%) in Q and in S. These data werecollected during 28 non consecutive days in the clinical unit in B, 59days in F, 42 days in Q and 63 days in S. The main drug-relatedproblems were inappropriate administration technique (293, 29%),untreated indication (254, 25%) and supra therapeutic dosage (106,11%). The pharmacist's interventions concerned mainly administrationmode optimization (223, 22%), dose adjustment (200, 20%) andtherapeutic monitoring (164, 16%). The three major drug classesleading to interventions were anti-infectives for systemic use (233,23%) and alimentary tract and metabolism drugs (218, 22%). Interventionsconcerned mainly residents and all clinical staff (209, 21%).Among the 879 (88%) interventions requiring a physician's approval,731 (83%) were accepted. Interventions were considered as having amoderate (51%) or major (17%) clinical impact. Among the interventionsprovided, 10% were considered to have an economicalpositive impact. Differences and similarities between countries willbe presented at the poster session.Discussion & Conclusion Decentralized pharmacist at patient bedsideis a pre-requisite for pharmaceutical care. There are limitedstudies comparing the activity of clinical pharmacists betweencountries. This descriptive study illustrates the ability of clinicalpharmacist to identify and solve drug-related problems in pediatricintensive care unit in four different francophone countries.

Safety of combined heat and moisture exchanger filters in long-term mechanical ventilation.

STUDY OBJECTIVE: To evaluate the safety of a combined heat and moisture exchanger filter (HMEF) for the conditioning of inspired gas in long-term mechanical ventilation (MV). DESIGN: Randomized controlled trial. SETTING: Medical ICU in a large teaching hospital. PATIENTS: One hundred fifteen consecutive patients who required > or = 48 h of MV. INTERVENTIONS: Patients were randomized at intubation time (day 1) to receive inspired gas conditioned either by a water-bath humidifier heated at 32 degrees C (HWBH) or by an HMEF (Hygroster; DAR; Mirandola, Italy). MEASUREMENTS AND MAIN RESULTS: The two study groups were comparable in terms of primary pathologic condition at the time of hospital admission, disease severity as measured by the Simplified Acute Physiology Score, and ICU mortality. They did not differ with respect to ventilator days per patient (mean +/- SD: HMEF, 7.6 +/- 6.5; HWBH, 7.8 +/- 5.8), incidence of endotracheal tube obstruction (HMEF, 0/59; HWBH, 1/56), and incidence of hypothermic episodes (HMEF, five; HWBH, two). In 41 patients receiving MV for > or = 5 days, the morphologic integrity of respiratory epithelium was evaluated on day 1 and day 5, using a cytologic examination of tracheal aspirate smears. The state of ciliated epithelium was scored on a scale from 0 (poorest integrity) to 1,200 (maximum integrity), according to a well-described method. In both patient groups, the scores slightly but significantly decreased from day 1 to day 5 (mean +/- SD: HWBH, from 787 +/- 104 to 745 +/- 88; HMEF, from 813 +/- 79 to 739 +/- 62; p < 0.01 for both groups); there were no statistically significant differences between groups. CONCLUSIONS: These data indicate acceptable safety of HMEFs of the type used in the present study for long-term mechanical ventilation.

Detrital zircon and micropalaeontological ages as new constraints for the lowermost tectonic unit (Talea Ori unit) of Crete, Greece

The Talea Ori unit is the lowermost known tectonic unit of Crete and the most external part of the Hellenides. Its stratigraphy ranges from Late Carboniferous to Oligocene and outcrops of the lower part are only known in the Talea Ori mountains (central Crete). In this area, a black sandstone at the base of the Galinos Beds, thought to be the oldest formation, contains zircons which were dated using the single grain evaporation method. The majority of these grains yielded Late Carboniferous ages (Variscan), while a small group yielded Early Proterozoic ages. The age distribution of these zircons suggests that, at the Carboniferous-Permian boundary, not much of the older North Gondwanan basement was exposed and that a river system carried detrital material from the Variscan belt towards the forming Neotethyan rift. Additionally, higher up in the stratigraphy benthic foraminifers (miliolids) were found in clasts from a conglomerate which was so far thought to be of Early Triassic age [Epting, M., Kudrass, H.-R., Leppig, U., Schaffer, A., 1972. Geologie der Talea Ori/Kreta. N. Jb. Geol. Palaont. Abh. 141, 259-285.]. These miliolids belong to the species Hoyenella inconstans [Michalik, J., Jendrejakova, O., Borza, K., 1979. Some new foraminifera species of the Fatra-Formation (Uppermost Triassic) in the West Carpathians. Geol. Carpath. 30 (1), 61-91.], thus attributing a Late Triassic (Carnian-Norian?) maximal age to this conglomerate. The carbonate platform from which the miliolids-bearing clasts come is not known. The presence to the north of a continuous hemipelagic record from the Carboniferous to the Triassic (Phyllite-Quartzite and Tripali units), attributed to the Palaeotethys realm, allows the Talea Ori unit and its lateral equivalents (the Ionian zone) to be assigned to the westward continuation of the Cimmerian block and therefore to the northern margin of the East Mediterranean Neotethys ocean.

Intranasal administration of the synthetic polypeptide from the C-terminus of the circumsporozoite protein of Plasmodium berghei with the modified heat-labile toxin of Escherichia coli (LTK63) induces a complete protection against malaria challenge.

Needle-free procedures are very attractive ways to deliver vaccines because they diminish the risk of contamination and may reduce local reactions, pain or pain fear especially in young children with a consequence of increasing the vaccination coverage for the whole population. For this purpose, the possible development of a mucosal malaria vaccine was investigated. Intranasal immunization was performed in BALB/c mice using a well-studied Plasmodium berghei model antigen derived from the circumsporozoite protein with the modified heat-labile toxin of Escherichia coli (LTK63), which is devoid of any enzymatic activity compared to the wild type form. Here, we show that intranasal administration of the two compounds activates the T and B cell immune response locally and systemically. In addition, a total protection of mice is obtained upon a challenge with live sporozoites.

Controlled expression of recombinant proteins in Physcomitrella patens by a conditional heat-shock promoter: a tool for plant research and biotechnology.

The ability to express tightly controlled amounts of endogenous and recombinant proteins in plant cells is an essential tool for research and biotechnology. Here, the inducibility of the soybean heat-shock Gmhsp17.3B promoter was addressed in the moss Physcomitrella patens, using beta-glucuronidase (GUS) and an F-actin marker (GFP-talin) as reporter proteins. In stably transformed moss lines, Gmhsp17.3B-driven GUS expression was extremely low at 25 degrees C. In contrast, a short non-damaging heat-treatment at 38 degrees C rapidly induced reporter expression over three orders of magnitude, enabling GUS accumulation and the labelling of F-actin cytoskeleton in all cell types and tissues. Induction levels were tightly proportional to the temperature and duration of the heat treatment, allowing fine-tuning of protein expression. Repeated heating/cooling cycles led to the massive GUS accumulation, up to 2.3% of the total soluble proteins. The anti-inflammatory drug acetyl salicylic acid (ASA) and the membrane-fluidiser benzyl alcohol (BA) also induced GUS expression at 25 degrees C, allowing the production of recombinant proteins without heat-treatment. The Gmhsp17.3B promoter thus provides a reliable versatile conditional promoter for the controlled expression of recombinant proteins in the moss P. patens.

Nutrient extraction and exportation by castor bean hybrid lyra

Information about nutrient extraction and exportation by crops, as well as the periods of highest nutrient demand is important for an adequate fertilization management. However, there are no studies on the nutrient uptake of short-stature hybrid castor bean. Therefore, the purpose of this study was to evaluate nutrient extraction and exportation by short-stature castor bean hybrid Lyra, in the spring-summer and fall-winter growing seasons. The experiments were conducted in the 2005/2006 spring-summer and 2006 fall-winter growing seasons on an Oxisol, in Botucatu, SP, in a randomized block design, with four replications. The plots consisted of plant samplings, which occurred 17, 31, 45, 59, 73, 97 and 120 days after emergence (DAE) in the spring-summer and 17, 31, 45, 59, 80, 100 and 120 DAE in fall-winter growing season. The growth of hybrid Lyra was slow and nutrient uptake lowest between emergence and the beginning of flowering. The period of highest dry matter (DM) accumulation rates and highest nutrient demand were observed 40 to 80 DAE, in both growing seasons. The order of nutrient extraction by the plants in the spring-summer growing season was: N>K>Ca>Mg>S>P>Fe>Mn>Zn>B>Cu>Mo. In fall-winter, S was more absorbed than Mg. Seed yield was higher in the spring-summer (2.995 kg ha-1), but nutrient extraction and exportation per ton of seed were similar in both growing seasons. Around 58 % of N and 84 % of P, and approximately half of the S and B absorbed throughout the cycle were exported with the seeds. However, most of the other nutrients accumulated in the plants returned to the soil in plant residues.

Anomalous specific-heat jump in a two-component ultracold Fermi gas

The thermodynamic functions of a Fermi gas with spin population imbalance are studied in the temperature-asymmetry plane in the BCS limit. The low-temperature domain is characterized by an anomalous enhancement of the entropy and the specific heat above their values in the unpaired state, decrease of the gap and eventual unpairing phase transition as the temperature is lowered. The unpairing phase transition induces a second jump in the specific heat, which can be measured in calorimetric experiments. While the superfluid is unstable against a supercurrent carrying state, it may sustain a metastable state if cooled adiabatically down from the stable high-temperature domain. In the latter domain the temperature dependence of the gap and related functions is analogous to the predictions of the BCS theory.

Automated DNA extraction using the QIAsymphony platform: Estimation of DNA recovery from simulated forensic stains

The aim of this study was to evaluate the forensic protocol recently developed by Qiagen for the QIAsymphony automated DNA extraction platform. Samples containing low amounts of DNA were specifically considered, since they represent the majority of samples processed in our laboratory. The analysis of simulated blood and saliva traces showed that the highest DNA yields were obtained with the maximal elution volume available for the forensic protocol, that is 200 ml. Resulting DNA extracts were too diluted for successful DNA profiling and required a concentration. This additional step is time consuming and potentially increases inversion and contamination risks. The 200 ml DNA extracts were concentrated to 25 ml, and the DNA recovery estimated with real-time PCR as well as with the percentage of SGM Plus alleles detected. Results using our manual protocol, based on the QIAamp DNA mini kit, and the automated protocol were comparable. Further tests will be conducted to determine more precisely DNA recovery, contamination risk and PCR inhibitors removal, once a definitive procedure, allowing the concentration of DNA extracts from low yield samples, will be available for the QIAsymphony.

Extraction sous guidage scopique et scanner des fuites de ciment para-vertebrale lors des cimentoplasties.

Objectifs: Exposer une nouvelle technique permettant le retrait de ciment extra-vertebral par fuite accidentelle lors du retrait du matériel. Matériels et méthodes: Nous injectons le ciment lorsque sa densité est celle d'une pâte dentifrice pour éviter les passages vasculaires. Lorsque la vertèbre est parfaitement remplie,nous patientons quelques minutes pour éviter la fuite de ciment le long du trajet (environ 4 a 6 cc en moyenne par vertèbre sont injectés). Malgré ces précautions,une fuite de ciment peut survenir lors du retrait du trocart. Cette complication est rare lorsque l'on prend les précautions nécessaires. Cependant, si la pressionintra-vertébrale est importante, le ciment peut être aspiré en dehors de la vertèbre. Résultats: L'aiguille du trocart est retirée pour être remplacée par une pince d'endoscopie 13 gauges. Sous guidage scopique, l'extraction se fait sous contrôle continu ; lapince retirant la fuite de ciment. Conclusion: La connaissance de cette intervention peut être très utile pour les équipes de radiologie interventionnelle , d'orthopédie et de neurochirurgie réalisant desvertébroplasties, pouvant être confrontées à ce type de problèmes.

Heat fluctuations in Brownian transducers

The heat fluctuation probability distribution function in Brownian transducers operating between two heat reservoirs is studied. We find, both analytically and numerically, that the recently proposed fluctuation theorem for heat exchange [C. Jarzynski and D. K. Wojcik, Phys. Rev. Lett. 92, 230602 (2004)] has to be applied carefully when the coupling mechanism between both baths is considered. We also conjecture how to extend such a relation when an external work is present.
