Abstract
BACKGROUND The incidence of non-AIDS defining cancer (NADC) is higher in people living with HIV (PLWH) than in the general population, and it is already one of the leading causes of death in the HIV-infected population. It is estimated that the situation will be aggravated by the progressive aging of PLWH. Early diagnosis through intensive cancer screening may improve the ability for therapeutic interventions and could be critical in reducing mortality, but it might also increase expenditure and harms associated with adverse events. The aim of this study is to evaluate an enhanced screening program for early diagnosis of cancer in PLWH compared to standard practice. The specific objectives are (1) to compare the frequency of cancer diagnosed at an early stage, (2) to analyze safety of the enhanced program: adverse events and unnecessary interventions, (3) to analyze the cost-utility of the program, and (4) to estimate the overall and site-specific incidence of NADC in PLWH. METHODS We will conduct a multicenter, non-blinded, randomized, controlled trial, comparing two parallel arms: conventional vs enhanced screening. Data will be recorded in an electronic data collection notebook. Conventional intervention group will follow the standard of care screening in the participating centers, according to the European AIDS Clinical Society recommendations, and the enhanced intervention group will follow an expanded screening aimed to early detection of lung, liver, anal, cervical, breast, prostate, colorectal, and skin cancer. The trial will be conducted within the framework of the Spanish AIDS Research Network Cohort (CoRIS). DISCUSSION The trial will evaluate the efficacy, safety, and efficiency of an enhanced screening program for the early diagnosis of cancer in HIV patients compared to standard of care practice. The information provided will be relevant since there are currently no studies on expanded cancer screening strategies in patients with HIV, and available data estimating cost effectiveness or cost-utility of such as programs are scarce. An enhanced program for NADC screening in patients with HIV could lead to early diagnosis and improve the prognosis of these patients, with an acceptable rate of unnecessary interventions, but it is critical to demonstrate that the benefits clearly outweigh the harms, before the strategy could be implemented.

Abstract
Positron annihilation lifetime spectroscopy is used to experimentally demonstrate the direct relationship between vacancies and the shift of the martensitic transformation temperature in a Ni_{55}Fe_{17}Ga_{28} alloy. The evolution of vacancies assisting the ordering enables shifts of the martensitic transformation up to 50 K. Our results confirm the role that both vacancy concentration and different vacancy dynamics play in samples quenched from the L2_{1} and B2 phases, which dictate the martensitic transformation temperature and its subsequent evolution. Finally, by electron-positron density functional calculations V_{Ni} is identified as the most probable vacancy present in Ni_{55}Fe_{17}Ga_{28}. This work evidences the capability of vacancies for the fine-tuning of the martensitic transformation temperature, paving the way for defect engineering of multifunctional properties.

Abstract
This paper shows that, for a large range of parameters, the journal editor prefers to delegate the choice to review the manuscript to the biased referee. If the peer review process is informative and the review reports are costly for the reviewers, even biased referees with extreme scientific preferences may choose to become informed about the manuscript's quality. On the contrary, if the review process is potentially informative but the reviewer reports are not costly for the referees, the biased reviewer has no incentive to become informed about the manuscript. Furthermore, if the reports are costly for referees but the peer review processes are not potentially informative, the biased reviewers will never become informed. In this paper, we also present a web resource that helps editors to experiment with the review process as a device for information transmission.

Abstract
La hemoglobinuria bacilar (HB) es una enfermedad infectocontagiosa, aguda, producida Clostridium haemolyticum, que afecta principalmente a bovinos y es predispuesta por diferentes factores. En este artículo se realiza un estudio retrospectivo de los casos de HB diagnosticados en bovinos de la provincia de Buenos Aires, por el Servicio de Diagnóstico Veterinario Especializado de INTA Balcarce durante el período 1969-2015 y los casos reportados por veterinarios privados en el Programa de Interacción Profesional en el área de influencia del Centro Regional Buenos Aires Sur del INTA durante el periodo 2001-2007. Se observó marcada estacionalidad de la enfermedad durante los meses de invierno y una asociación con un avanzado estado de preñez de los animales (88% de los casos). Solo en un 15,9 % de los casos se pudo confirmar una infestación simultánea con Fasciola hepatica en los rodeos donde se diagnosticó la enfermedad. En un 47,9 % de estos episodios los animales habían recibido previamente dos dosis de vacuna contra HB. HB es endémica e insidiosa en ciertas regiones de nuestro país. La información sobre algunos aspectos de su etiopatogenia y el control es escasa, dificultando su prevención. Estas áreas deberían ser exploradas en el futuro para tratar de mejorarlas.

Abstract
OBJECTIVES Contemporary data from country-wide cohorts are needed to reveal trends in the occurrence of acute myocardial infarction (AMI) in people living with HIV (PLWH). We analysed time trends in the standardized incidence rate (sIR) of AMI in PLWH in Spain from 2004 to 2015, and compared them with trends in the general population. METHODS A longitudinal study in a nationwide contemporary multicentre HIV-infected cohort was carried out. Data on all incident AMI events were collected, and age- and sex-standardized IRs calculated. To analyse the IR of AMI in the general population, the national rates of hospital discharges for AMI per 100 000 inhabitants stratified for age and sex from 2004 to 2015 were obtained using the morbidity report data from the National Statistics Institute. A Poisson regression model was fitted to assess the effect of covariates of interest on AMI occurrence. RESULTS The sIRs of AMI in 2004-2015 were 237.92 [95% confidence interval (CI) 225.95-249.90] and 66.75 (95% CI: 23.49-110.01) per 100 000 patient-years in male and female PLWH, respectively. There was a decrease in the sIR of AMI in male PLWH from 279.02 (95% CI: 265.46-292.59) per 100 000 person-years in 2004-2009 to 222.13 (95% CI: 210.83-233.42) per 100 000 person-years in 2010-2015. Compared with the general population, the sIR ratio was 1.41 (95% CI: 1.26-1.55) in 2004-2009, and 1.28 (95% CI: 1.15-1.43) in 2010-2014. AMI occurrence was associated with older age (P < 0.066 for each 10-year age stratum ≥ 35-years compared with the 25-34 year stratum), higher plasma HIV RNA (P < 0.001), lower CD4 count (P < 0.04 for CD4 strata > 350 cells/μL compared with the 0-100 cells/μL stratum), and the period 2004-2009 (P < 0.001). CONCLUSIONS There has been a decreasing incidence of AMI in PLWH in Spain, associated with improving immune and virological status, but the incidence of AMI has remained higher than in the general population.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is the most frequent primary malignant liver tumor, with the Milan criteria considered to be the gold standard for patient selection for liver transplantation (LT). MATERIALS AND METHODS We performed a descriptive observational study, reviewing 20 years of experience of LT in patients with HCC in the Fundacion Valle del Lilí in Cali, Colombia. Subgroup analysis was undertaken for periods 1999 to 2007 and 2008 to 2015. RESULTS Fifty-seven cases with a pretransplant HCC diagnosis were reviewed. In the first period patients within the Milan criteria had a recurrence-free survival at 5 years of 66.6%, and in those who exceeded the Milan criteria, recurrence-free survival was 75%. In the second period, patients within the Milan criteria, recurrence-free survival at 5 years was 93.5%, and in those who exceeded the Milan criteria, recurrence-free survival was 75.7%. No statistically significant difference was found in either period. For patients with mild and moderate tumor differentiation, the relapse survival rate at 5 years was 69.4% (95% confidence interval [CI] 35.8-87.8) and 74.7% (95% CI 44.5-90), respectively. All patients with poor tumor differentiation relapsed and died within 3 years. CONCLUSION Global and recurrence-free survival among patients who met and patients who exceeded the Milan criteria was not significantly different, suggesting an expansion of the Milan criteria to include potential recipients who were previously excluded. Obtaining histologic differentiation and identifying vascular invasion will provide a more worthwhile contribution to LT decision making.

Abstract
The most compelling candidates for Dark Matter to day are WIMPs and axions. The applicability of gasesous Time Projection Chambers (TPCs) with Micromesh Gas Structures (Micromegas) to the search of these particles is explored within this work. Both particles would produce an extremely low rate at very low energies in particle detectors. Micromegas detectors can provide both low background rates and low energy threshold, due to the high granularity, radiopurity and uniformity of the readout. Small (few cm wide) Micromegas detectors are used to image the axion-induced x-ray signal expected in the CERN Axion Solar Telescope (CAST) experiment. We show the background levels obtained in CAST and the prospects to further reduce them to the values required by the Internation Axion Observatory (IAXO). We also present TREX-DM, a scaled-up version of the Micromegas used in axion research, but this time dedicated to the low-mass WIMP detection. TREX-DM is a high-pressure Micromegas-based TPC designed to host a few hundreds of grams of light nuclei (argon or neon) with energy thresholds potentially at the level of 100 eV. The detector is described in detail, as well as the results of the commissioning and characterization phase on surface. Besides, the background model of TREX-DM is presented, along with the anticipated sensitivity of this search, which could go beyond current experimental limits.

Abstract
OBJECTIVE Pilot project focusing on the implementation and evaluation of a health education (HE) program for inmates of the prison of Ocaña I (Spain). The objective was to analyze the intentions for change in health habits and perceptions, and to assess whether the HE-program had differential effects depending on whether the participants belonged to the PAIEM or not and their socio-demographic characteristics. METHODOLOGY The participants were 65 men, who answered an ad hoc questionnaire at the end of each session. Data analysis applied was univariate and bivariate (one-way ANOVA, t-test for Equality of Means and Chi-Square test). RESULTS The average rating of the sessions was 3.51 out of 4 (SD = 0.62). The percentage of positive answers about the intention to adopt healthy habits was higher among non-PAIEM subjects (84.8%) than among those who were part of this program (57.9%). All subjects having a couple indicated an intention to change negative habits, compared to 67.3% for those without a couple. The percentage of subjects who said that their perception on the issue had changed was highest among those without education (89.7%) than among those with education (61.5%). CONCLUSIONS The evaluation of implanted HE-program implemented in the Ocaña I prison was very positive, there are differences between subjects belonging to the PAIEM and those who do not.

Abstract
The heating properties of Fe71.7Si11B13.4Nb3Ni0.9 amorphous glass-coated microwires are explored for prospective applications in magnetic hyperthermia. We show that a single 5 mm long wire is able to produce a sufficient amount of heat, with the specific loss power (SLP) reaching a value as high as 521 W/g for an AC field of 700 Oe and a frequency of 310 kHz. The large SLP is attributed to the rectangular hysteresis loop resulting from a peculiar domain structure of the microwire. For an array of parallel microwires, we have observed an SLP improvement by one order of magnitude; 950 W/g for an AC field of 700 Oe. The magnetostatic interaction strength essential in the array of wires can be manipulated by varying the distance between the wires, showing a decreasing trend in SLP with increasing wire separation. The largest SLP is obtained when the wires are aligned along the direction of the AC field. The origin of the large SLP and relevant heating mechanisms are discussed.

Abstract
Over the past two decades, magnetic hyperthermia and photothermal therapy are becoming very promising supplementary techniques to well-established cancer treatments such as radiotherapy and chemotherapy. These techniques have dramatically improved their ability to perform controlled treatments, relying on the procedure of delivering nanoscale objects into targeted tumor tissues, which can release therapeutic killing doses of heat either upon AC magnetic field exposure or laser irradiation. Although an intense research effort has been made in recent years to study, separately, magnetic hyperthermia using iron oxide nanoparticles and photothermal therapy based on gold or silver plasmonic nanostructures, the full potential of combining both techniques has not yet been systematically explored. Here we present a proof-of-principle experiment showing that designing multifunctional silver/magnetite (Ag/Fe3O4) nanoflowers acting as dual hyperthermia agents is an efficient route for enhancing their heating ability or specific absorption rate (SAR). Interestingly, the SAR of the nanoflowers is increased by at least 1 order of magnitude under the application of both an external magnetic field of 200 Oe and simultaneous laser irradiation. Furthermore, our results show that the synergistic exploitation of the magnetic and photothermal properties of the nanoflowers reduces the magnetic field and laser intensities that would be required in the case that both external stimuli were applied separately. This constitutes a key step toward optimizing the hyperthermia therapy through a combined multifunctional magnetic and photothermal treatment and improving our understanding of the therapeutic process to specific applications that will entail coordinated efforts in physics, engineering, biology, and medicine.

Abstract
If Dark Matter is made of Weakly Interacting Massive Particles (WIMPs) with masses below [Formula: see text] GeV, the corresponding nuclear recoils in mainstream WIMP experiments are of energies too close, or below, the experimental threshold. Gas Time Projection Chambers (TPCs) can be operated with a variety of target elements, offer good tracking capabilities and, on account of the amplification in gas, very low thresholds are achievable. Recent advances in electronics and in novel radiopure TPC readouts, especially micro-mesh gas structure (Micromegas), are improving the scalability and low-background prospects of gaseous TPCs. Here we present TREX-DM, a prototype to test the concept of a Micromegas-based TPC to search for low-mass WIMPs. The detector is designed to host an active mass of [Formula: see text] kg of Ar at 10 bar, or alternatively [Formula: see text] kg of Ne at 10 bar, with an energy threshold below 0.4 keVee, and is fully built with radiopure materials. We will describe the detector in detail, the results from the commissioning phase on surface, as well as a preliminary background model. The anticipated sensitivity of this technique may go beyond current experimental limits for WIMPs of masses of 2-8 GeV.

Abstract
PURPOSE To analyse the prognostic role of the immunohistochemical expression of pKDR in patients with advanced colorectal cancer treated with oxaliplatin and fluoropyrimidines combination chemotherapy with or without bevacizumab. METHODS Retrospective multicentre study, carried out at four hospitals in the Valencian Community (Spain). Patients evolution was compared based on the immunohistochemical expression of pKDR, classified using 4 categories: 0 (undetectable), 1 (mild), 2 (moderate) and 3 (high intensity). Patients were divided into two groups for the analysis: group 1 with low expression (0-1) vs. group 2 with high expression (2-3). RESULTS Histological samples for the pKDR analysis were available for 84 of the 112 patients selected. Seven (8.3 %) had undetectable or mild expression of pKDR (Group 1) and 77 (91.7 %) showed moderate or high expression of pKDR (Group 2). Response rate in Group 1 was 100 % compared to 54.2 % in Group 2 (p = 0.019). Progression-free survival (PFS) (15 vs. 12 months, p = 0.4) and overall survival (OS) (28 vs. 22 months, p = 0.09) were numerically but not significantly higher in patients from Group 1 vs. Group 2. Patients from Group 2 who received bevacizumab presented a significantly higher PFS (13 vs. 11, p = 0.015) and a numerically higher OS (23 vs. 17 months, p = 0.27) than those treated exclusively with chemotherapy. CONCLUSIONS Our results suggest that the absence or low expression of pKDR is associated with a better prognostic profile in patients with advanced colorectal cancer treated with chemotherapy and bevacizumab. Patients with a high pKDR expression benefit from the combination of chemotherapy with bevacizumab.

Abstract
Exposure to the tellurium oxyanion tellurite (TeO3(2-)) results in the establishment of an oxidative stress status in most microorganisms. Usually, bacteria growing in the presence of the toxicant turn black because of the reduction of tellurite (Te(4+)) to the less-toxic elemental tellurium (Te(0)). In vitro, at least part of tellurite reduction occurs enzymatically in a nicotinamide dinucleotide-dependent reaction. In this work, we show that TeO3(2-) reduction by crude extracts of Escherichia coli overexpressing the zwf gene (encoding glucose-6-phosphate dehydrogenase) takes place preferentially in the presence of NADPH instead of NADH. The enzyme responsible for toxicant reduction was identified as 6-phosphogluconate dehydrogenase (Gnd). The gnd gene showed a subtle induction at short times after toxicant exposure while strains lacking gnd were more susceptible to the toxicant. These results suggest that both NADPH-generating enzymes from the pentose phosphate shunt may be involved in tellurite detoxification and resistance in E. coli.

Abstract
BACKGROUND Endemic goiter remains a serious public health problem and 75 % of people affected live in underdeveloped countries where treatment is difficult for various reasons. The aim of this article is to report our experience in African countries with the management and surgical treatment of endemic goiter, performed in a nonhospital setting and without general anesthesia in the context of a collaborative development project by experienced endocrine surgeons. METHODS Fifty-six black African patients with a goiter were studied. Those in poor general health, the elderly, patients with either small goiters or clinical hyperthyroidism, and those presenting with an acute episode of malaria were excluded from the study. Cervical epidural anesthesia with spontaneous ventilation was used and a partial thyroidectomy was performed. The technique used, its immediate complications, and early and late follow-up were analyzed. RESULTS Surgery was performed on 31 patients with grades 3 and 4 goiter without mortality and a morbidity rate of 11.9 %, with 97 % of all complications being minor. There were no instances of dysphonia or symptomatic hypocalcemia and the mean stay was 1.57 days (range 1.25-1.93). Follow-up in the first year was 71 % and no case of severe or recurrent hypothyroidism was detected. CONCLUSIONS Surgery without general anesthesia performed in a nonhospital setting in underdeveloped countries in patients with goiter is a viable option with good results and low morbidity.

Abstract
The CERN Axion Solar Telescope has finished its search for solar axions with (3)He buffer gas, covering the search range 0.64 eV ≲ ma ≲ 1.17 eV. This closes the gap to the cosmological hot dark matter limit and actually overlaps with it. From the absence of excess x rays when the magnet was pointing to the Sun we set a typical upper limit on the axion-photon coupling of gaγ ≲ 3.3 × 10(-10) GeV(-1) at 95% C.L., with the exact value depending on the pressure setting. Future direct solar axion searches will focus on increasing the sensitivity to smaller values of gaγ, for example by the currently discussed next generation helioscope International AXion Observatory.

Abstract
A novel method for superparamagnetic nanoparticle detection using copper impedance as the sensing property is presented. The increase of impedance produced by the proximity of the nanoparticles in the copper is comparable to that of classical magnetoimpeditive materials. A physical interpretation of the detection in terms of the induction of eddy currents in the copper element by the oscillating magnetic moments of the particles is proposed. Experimental research has been done to support this hypothesis, namely, analyses of the influence of the driving current frequency and amplitude, and of the geometry and size of the sensing conductor. The ability of copper to quantify the number of nanoparticles was successfully verified, evidencing the great potential of this new method.

Abstract
The CERN Axion Solar Telescope (CAST) has extended its search for solar axions by using (3)He as a buffer gas. At T=1.8 K this allows for larger pressure settings and hence sensitivity to higher axion masses than our previous measurements with (4)He. With about 1 h of data taking at each of 252 different pressure settings we have scanned the axion mass range 0.39 eV≲m(a)≲0.64 eV. From the absence of excess x rays when the magnet was pointing to the Sun we set a typical upper limit on the axion-photon coupling of g(aγ)≲2.3×10(-10) GeV(-1) at 95% C.L., the exact value depending on the pressure setting. Kim-Shifman-Vainshtein-Zakharov axions are excluded at the upper end of our mass range, the first time ever for any solar axion search. In the future we will extend our search to m(a)≲1.15 eV, comfortably overlapping with cosmological hot dark matter bounds.

Abstract
This study investigated simultaneous treatments in contextual interference (blocked and random practice) and their effect on the process of learning four tennis shots. 8 tennis players participated in the research, which was carried out in two phases. The first phase involved a 3-wk. period of 12 sessions with 192 practice tennis shots per session for each tennis player. The second phase comprised 4 retention tests carried out at 48 hr. and 2, 4, and 6 weeks following the learning phase. This phase consisted of evaluating the retention of the skills that had been practiced during the learning phase. The results indicated an improvement in the quality of shots for both practice conditions during the learning phase. Differences in retention appeared relative to differences in the type of practice conditions (random or blocked) in which the skill was learned and also depended on the type of shot and the time that had elapsed since the learning period.

Abstract
BACKGROUND Despite years of experience with lung transplantation, perioperative morbidity rates remain high. The objective of this study was to analyze our series of lung transplant recipients, seeking to identify possible intra- and postoperative risk factors associated with mortality. PATIENTS AND METHODS We performed a descriptive, retrospective study of 224 consecutive patients undergoing lung transplantation over a period of 112 months; we excluded retransplant procedures. We gathered details of the surgical procedure and postoperative period in the recovery unit. Univariate analysis using the chi-square test identified variables associated with the incidence of mortality. RESULTS From 1999 to 2008, we performed 224 lung transplants, including 66% in men and 34% in women. Their overall mean age was 49.9 +/- 13.5 years. The conditions that led to transplantation were pulmonary fibrosis (38.4%); chronic obstructive pulmonary disease emphysema (29%); cystic fibrosis (10.7%); bronchiectasis (8.9%); pulmonary hypertension (3.1%); and other diseases (9.9%). A total of 124 (55.4%) patients underwent single and 100 (44.6%) received sequential bilateral lung transplantations. Surgical risk factors were identified in 51.3% of the cases, the most frequent being hemorrhage (25.3%), followed by severe pulmonary hypertension (14.7%) and cardiopulmonary bypass (12.1%). Greater perioperative mortality was detected among patients with surgical risk factors, namely, significantly related to cardiopulmonary bypass, pulmonary hypertension, and air leak. A higher frequency of surgical risk factors was observed among patients with bilateral lung transplantations and longer procedures, but they were not associated with greater perioperative mortality. Reoperation was necessary in 16 patients (7.2%), mainly owing to bleeding, it was not significantly related to mortality risk. CONCLUSIONS The incidence of surgical risk factors in lung transplantation was high, especially in bilateral lung transplantations and prolonged procedures. Postoperative bleeding requiring reoperation was not frequent and not associated with increased preoperative mortality in our series.

Abstract
INTRODUCTION The indication for single or double lung transplantation in patients diagnosed with pulmonary emphysema is a topic of current debate. Our aim was to analyze the differences in the incidence of perioperative complications, survival, and quality of life between single and double lung transplantations. MATERIALS AND METHODS From 1999 to 2008, 223 subjects underwent transplantation in our department, of whom 62 (28%) had a previous diagnosis of pulmonary emphysema. A retrospective study was performed to establish possible differences between group 1 (single lung) and group 2 (double lung) transplants analyzing overall survival using the Kaplan-Meier method and differences between groups using the log-rank test. Pearson chi-square test was used to compare the frequency of postoperative complications, bronchiolitis obliterans BOS acute rejection episodes, and infections. RESULTS We included 62 patients who underwent transplantation for emphysema. Cumulative 5-year survival rate, excluding preoperative mortality, was 54% overall, 59% for group 1, and 56% for group 2. No significant differences were observed between the groups (P = .47). The frequency of BOS was 34% in group 1 and 42% in group 2 (P = .52). At least 1 acute rejection episode occurred in 52% of group 1 patients and 51% of group 2 patients (P = .98). Bacterial infections were experienced by 50% of group 1 patients and 54% of group 2 patients (P = .72). Fungal infections affected 10% of group 1 patients and 15% of group 2 patients (P = .71). Intraoperative complications were recorded in 27.6% of group 1 patients versus 54% of group 2 patients, a difference that was statistically significant (P = .032). CONCLUSIONS The study results supported the decision of our group to consider single lung transplantation the treatment of choice in emphysema, which may be complemented with volume reduction surgery in the native lung or subsequent transplantation of the contralateral lung.

Abstract
INTRODUCTION The major limiting factor for lung transplantation (LT), both worldwide and in Spain, is the number of suitable lung donors. This, together with the increased demand for LT, led us to propose the performance of 2 single lung transplantations simultaneously using the same donor (the "twinning procedure"). OBJECTIVE The objective of this study was to analyze the outcome of patients who underwent transplantation with this procedure, assessing differences between the first and the second transplant. PATIENTS AND METHODS From November 2001 to August 2008, 46 single lung transplantations (SLTs) were performed with 23 donors. RESULTS The mean ischemia time was 258 minutes (median, 265) for the first transplantation and 312 minutes (median, 320) for the second transplantation. Primary graft dysfunction occurred in 5 patients (24%) in the first group and 9 in the second group (39%; P = .27). The median intubation time was 8 hours for the first and 6.5 hours for the second group. The mean hospital stay was 39 and 31 days, respectively. Postoperative mortality was 2 (8.7%) and 3 (13%) patient, respectively (P = .99). There was no significant difference in the incidence of acute rejection episodes, infections, or chronic rejections. Five-year survival rates were 67.9% for the first and 61.5% for the second (Kaplan-Meier). CONCLUSIONS The performance of 2 SLTs using the same donor and in the same hospital was feasible with adequate planning, permitting better use of donors and reducing waiting list time and mortality. Our results showed no increased risk for recipients of the second transplant in the early postoperative and long-term periods.

Abstract
In Arabidopsis thaliana Columbia (Col-0) plants, the restriction of Tobacco etch virus (TEV) long-distance movement involves at least three dominant RTM (restricted TEV movement) genes named RTM1, RTM2, and RTM3. Previous work has established that, while the RTM-mediated resistance is also effective against other potyviruses, such as Plum pox virus (PPV) and Lettuce mosaic virus (LMV), some isolates of these viruses are able to overcome the RTM mechanism. In order to identify the viral determinant of this RTM-resistance breaking, the biological properties of recombinants between PPV-R, which systemically infects Col-0, and PPV-PSes, restricted by the RTM resistance, were evaluated. Recombinants that contain the PPV-R coat protein (CP) sequence in an RTM-restricted background are able to systemically infect Col-0. The use of recombinants carrying chimeric CP genes indicated that one or more PPV resistance-breaking determinants map to the 5' half of the CP gene. In the case of LMV, sequencing of independent RTM-breaking variants recovered after serial passages of the LMV AF199 isolate on Col-0 plants revealed, in each case, amino acid changes in the CP N-terminal region, close to the DAG motif. Taken together, these findings demonstrate that the potyvirus CP N-terminal region determines the outcome of the interaction with the RTM-mediated resistance.

Abstract
OBJECTIVE To assess the preoperative management in our emergency surgical service and to improve the quality of the care provided to patients. MATERIAL AND METHODS In order to find the causes of non-compliance, the Ishikawa Fishbone diagram was used and eight assessment criteria were chosen. The first assessment includes 120 patients operated on from January to April 2007. Corrective measures were implemented, which consisted of meetings and conferences with doctors and nurses, insisting on the importance of the informed consent as a legal document which must be signed by patients, and the obligation of giving a copy to patients or relatives. The second assessment includes the period from July to October 2007 (n=120). RESULTS We observed a high non-compliance of C1 signing of surgical consent (CRITERION 1: all patients or relatives have to sign the surgical informed consent for the operation to be performed [27.5%]) and C2 giving a copy of the surgical consent (CRITERION 2: all patients or relatives must have received a copy of the surgical informed consent for the Surgery to be performed [72.5%]) and C4 anaesthetic consent copy (CRITERION 4: all patients or relatives must have received a copy of the Anaesthesia informed consent corresponding to the operation performed [90%]). After implementing corrective measures a significant improvement was observed in the compliance of C2 and C4. In C1 there was an improvement without statistical significance. CONCLUSIONS The carrying out of an improvement cycle enabled the main objective of this paper to be achieved: to improve the management of informed consent and the quality of the care and information provided to our patients.

Abstract
Cathodoluminescence and photoluminescence techniques have been used to investigate room temperature light emission from beta-Ga(2)O(3):Eu nanostructures, which were obtained by two methods. In one of them, a mixture of Ga(2)O(3)/Eu(2)O(3) powders was used as precursor material and annealed under an argon flow. In the other one, undoped beta-Ga(2)O(3) nanostructures were first obtained by thermal oxidation of metallic gallium and europium was subsequently incorporated by a diffusion process. Room temperature luminescence at 610 nm due to Eu(3+) intraionic transitions from beta-Ga(2)O(3):Eu has been observed. Waveguiding of this red emitted light through the structures was shown.

Abstract
In vitro activity of fosfomycin, compared with other antibiotics used for urinary tract infections (UTI), against extended spectrum beta-lactamase (ESBL)-producing Escherichia coli and Klebsiella pneumoniae clinical isolates obtained from UTIs, was determined. The activity of fosfomycin, co-trimoxazole, ciprofloxacin, nitrofurantoin, amoxicillin/clavulanic acid and gentamicin against 71 ESBL-producing E. coli clinical isolates and 13 ESBL-producing K. pneumoniae clinical isolates obtained from UTI was studied by the agar-dilution method or E-test. E. coli isolates produced mainly CTX-M type ESBL (76.1%), especially CTX-M 14 (56.3%). K. pneumoniae isolates produced most predominantly SHV-type ESBL (92.3%), mainly SHV-2 (76.9%). Gentamicin (4.4%), fosfomycin (5.6%) and nitrofurantoin (5.6%) showed the lowest resistance proportions against E. coli. Co-trimoxazole and ciprofloxacin (7.7%) showed the lowest resistance proportions against K. pneumoniae.

Abstract
Primary ovarian lymphoma is a rare entity. We submit a case of a 34-year-old black patient presenting with a bilateral adnexal tumor. She underwent hysterectomy with double salpingo-oophorectomy followed by polychemotherapy treatment. Histology confirmed Epstein-Barr virus-positive bilateral Burkitt's lymphoma. The patient died from septic shock after a month of treatment. Endemic Burkitt's lymphoma has a predilection for the female genital tract, manifesting itself clinically as a pelvic mass and less frequently as a menstrual disorder. It is a rare entity in our environment but should be kept in mind when treating patients of African origin.

Abstract
Hafnia alvei, a Gram negative bacillus related to the Enterobacteriaceae family, is considered an opportunistic pathogen of several animal species and humans. In this communication, we describe fimbrial-like structures from different strains of H. alvei that cannot be easily ascribed to any of the previously reported fimbrial types in this species (type I or type III). Polymerase chain reaction (PCR) and immunofluorescence assays were carried out to study fimbriae and flagella in H. alvei strains isolated from different sources. No correlation between the results obtained by PCR and those obtained by phenotypic methods were found, and the antibodies used gave cross or different recognition patterns of the surface structures present in these strains. We report as well that strain and growth temperature influence fimbriation and expression of flagella in human and animal isolates of H. alvei. This study also indicates that the absence of fimbriae have a significant positive influence on the initial adhesion of H. alvei to human epithelial cells.

Abstract
This investigation examined the effects of distributed and massed practice on the learning and retention of a discrete computerized skill (Exp. 1) and a continuous computerized skill (Exp. 2). 40 men were randomly assigned to one of four groups, of which two groups took part in Exp. 1 and two groups in Exp. 2. Performance was assessed at various points during acquisition and then on 8 retention tests conducted at varying times after acquisition. Learning curves for practice were highly similar for the two conditions. Participants in the distributed-practice group performed significantly better than those in the massed-practice group at the end of practice on both the discrete and continuous skills. However, participants in the distributed-practice group performed significantly more poorly on retention during 24 hr. and after acquisition. Participants in the massed-practice condition performed significantly better on retention tests than did those who learned in the distributed-practice condition.

Abstract
phi29 DNA-containing 12-13- particles (produced by infecting nonsuppressor hosts of Bacillus subtilis with phage containing suppressible mutations in cistrons 12 and 13) can be complemented with lysates containing proteins p12* and p13 to yield infectious phage. Complementation of these particles with lysates containing p12* but not p13 or complementation with purified p12* in the absence of p13 produces a structure (called complex) which has a markedly different organization. Electron microscopy and sedimentation analysis after digestion with DNase I or proteinase K indicate that complex is composed of an intact phage head with a genome-sized linear DNA molecule attached at the collar-tail region. EcoRI digestion establishes that the DNA molecule has a unique orientation. Gel electrophoresis indicates that p12*, the neck appendage protein, is transferred to the particles when complex is formed. Complex can also be produced by incubation of 12-13- particles at 42 degrees , by incubation at pH 6.0, or by incubation in the presence of 20 mM EDTA. Complex is also formed from DNA-containing 12- particles but to a lesser extent.

Abstract
We report the case of a 29-year-old man with hemoptysis. The patient came to the emergency department, where a laboratory test and chest radiograph were reported as normal. The following day the patient again had hemoptysis, though less than previously. He reported no chest pain, dyspnea, fever, catarrh, changes in urine or feces, contact with patients with bacillus disease or constitutional symptoms. Doppler ultrasound of the chest showed right basal parenchymatous condensation containing a vessel with arterial flow (in the opposite direction to the aortic flow) compatible with an aberrant vessel, possibly a sequestration, leaving the aorta above the celiac trunk. Because of the findings of the chest echogram and magnetic resonance study, thoracoabdominal computed tomography angiography was undertaken; this showed right basal condensation and an anomalous vessel originating 1 cm above the celiac trunk, supplying the right lower lobe. An aortic and pulmonary arteriogram via an arterial and right femoral vein approach confirmed the findings. The patient was treated successfully with percutaneous embolization with coils. The relevant literature is reviewed.

Abstract
Abstract. The main objectives of this work are to analyze, firstly, the detail of the causes of a low ozone event which occurred in January 2006 and, secondly, the related effects of this anomalous episode on ultraviolet (UV) radiation measured at three locations in Extremadura (South-Western Spain). On 19 January 2006, the OMI total ozone column (TOC) was 16–20% below the January mean value of TOMS/NASA TOC (period 1996–2005). The back trajectories analysis with the HYSplit model indicates that the notable decrease of TOC could be attributed to a fast rise of the isentropic trajectories height. Concomitantly, UV erythemal radiation greatly increases (between 23% and 37%) on 19 January 2006 respect to UV erythemal radiation measured on 19 January 2005. This notable increase in winter UV solar radiation may involve harmful effects for organisms adapted to receive less radiation during that season (e.g. early developmental stages of terrestrial plants and phytoplankton).
