Abstract
Abstract
Thermo-mechanical performance of fuel rods is a key aspect for assessing the spent fuel safety during dry storage. There is a need of assessing fuel rod behaviour codes for dry storage stage and uncertainty quantification can be a useful tool for this assessment. As a first step of these studies, sensitivity analyses can help to understand the effects and to identify the relevant parameters for the predictions. The present work studies the effect of the scenario on sensitivity analyses focused on the cladding stress at the beginning of dry storage. To make this comparison 10 design parameter’s tolerances and 7 model biases have been studied for 2 different fuel rods in terms of design and irradiation. Cladding diameter tolerance and fuel gas release and thermal conductivity model biases are the more influencing parameters independently of the scenario chosen. Overall, moderate differences between scenarios have been obtained. Results obtained in this work are specifically related to the modelling of the code FRAPCON-xt.

Abstract
AbstractThe research on safety of dry stored nuclear fuel poses a number of challenges related to understand and predict its performance under the anticipated conditions. The ultimate goal is the development of analytical capabilities for predicting the integrity of the fuel rod. In this regard, the research carried out by the Unit of Nuclear Safety Research of CIEMAT is enabling the use of predictive tools and analysis methodologies whereby safety conditions can be assessed. To do so, the experience gained in fuel rod thermal-mechanics in reactor is used as a basis; particularly, the fuel performance code FRAPCON is being extended to the dry storage technology, called FRAPCON-xt. This paper shows the work carried out so far, including some applications on aspects related to cladding embrittlement due to hydrides as one of the main concerns.

Abstract
OBJECTIVES The objectives of this study were to investigate the acceptability of rapid HIV testing among general practitioners in Spain and to identify perceived barriers and needs in order to implement rapid testing in primary care settings. METHODS An anonymous questionnaire was distributed online to all members of the two largest Spanish scientific medical societies for family and community medicine. The study took place between 15th June and 31st October 2010. RESULTS Completed questionnaires were returned by 1308 participants. The majority (90.8%) of respondents were General Practitioners (GP). Among all respondents, 70.4% were aware of the existence of rapid tests for the diagnosis of HIV but they did not know how to use them. Nearly 80% of participants would be willing to offer rapid HIV testing in their practices and 74.7% would be confident of the results obtained by these tests. The barriers most commonly identified by respondents were a lack of time and a need for training, both in the use of rapid tests (44.3% and 56.4%, respectively) and required pre- and post-test counselling (59.2% and 34.5%, respectively). CONCLUSIONS This study reveals a high level of acceptance and willingness on the part of GPs to offer rapid HIV testing in their practices. Nevertheless, the implementation of rapid HIV testing in primary care will not be possible without moving from comprehensive pre-test counselling towards brief pre-test information and improving training in the use of rapid tests.

Abstract
PURPOSE To show turnaround time to client source in eight laboratories covering eight Health Areas (2,014,475 inhabitants) of the Valencian Community (Spain). MATERIAL AND METHODS Internal Laboratory Information System (LIS) registers (test register and verification date and time), and daily LIS registers were used to design the indicators, These indicators showed the percentage of key tests requested (full blood count and serum glucose and thyrotropin) that were validated on the same day the blood was taken (inpatients and Primary Care and/or at 12 a.m. (inpatients). Urgent (stat) tests were also registered as key tests (serum troponin and potassium) and were recorded in minutes. Registers were collected and indicators calculated automatically through a Data Warehouse application and OLAP cube software. RESULTS Long turnaround time differences were observed at 12 a.m. in inpatients, and in the day of sample extraction in primary care patients. The variability in turnaround of stat tests is related to hospital size, activity and validation by the laboratory physician. CONCLUSIONS The study results show the large turnaround time disparity in eight Health Care Areas of Valencian Community. The various requesting sources covered by the laboratories create the need for continuous mapping processes redesign and benchmarking studies to achieve customer satisfaction.

Abstract
We describe the use of antisense morpholino oligonucleotides (AMOs) to restore normal splicing caused by intronic molecular defects identified in methylmalonic acidemia (MMA) and propionic acidemia (PA). The three new point mutations described in deep intronic regions increase the splicing scores of pseudoexons or generate consensus binding motifs for splicing factors, such as SRp40, which favor the intronic inclusions in MUT (r.1957ins76), PCCA (r.1284ins84), or PCCB (r.654ins72) messenger RNAs (mRNAs). Experimental confirmation that these changes are pathogenic and cause the activation of the pseudoexons was obtained by use of minigenes. AMOs were targeted to the 5? or 3? cryptic splice sites to block access of the splicing machinery to the pseudoexonic regions in the pre-mRNA. Using this antisense therapeutics, we have obtained correctly spliced mRNA that was effectively translated, and propionyl coenzyme A (CoA) carboxylase (PCC) or methylmalonylCoA mutase (MCM) activities were rescued in patients' fibroblasts. The effect of AMOs was sequence and dose dependent. In the affected patient with MUT mutation, close to 100% of MCM activity, measured by incorporation of (14)C-propionate, was obtained after 48 h, and correctly spliced MUT mRNA was still detected 15 d after treatment. In the PCCA-mutated and PCCB-mutated cell lines, 100% of PCC activity was measured after 72 h of AMO delivery, and the presence of biotinylated PCCA protein was detected by western blot in treated PCCA-deficient cells. Our results demonstrate that the aberrant inclusions of the intronic sequences are disease-causing mutations in these patients. These findings provide a new therapeutic strategy in these genetic disorders, potentially applicable to a large number of cases with deep intronic changes that, at the moment, remain undetected by standard mutation-detection techniques.

Abstract
BACKGROUND The Spanish Family Medicine National Commission is proposing a new portfolio-type Specialist Training Book (STB). OBJECTIVE To pilot its contents, structure, and implementation strategies. DESIGN Cross-sectional, descriptive study. SETTING A Provincial Family Medicine Teaching Unit. PARTICIPANTS Twenty-eight tutors and 36 residents. METHODS For 9 months the participants conducted a training assessment on diverse areas of competence by means of tasks at work. Tutors recorded information on the quality of reflection achieved by residents and the tasks they performed by means of the card model proposed in the STB. Residents filled in an ad hoc survey. A univariate analysis of quantitative data was conducted. RESULTS Thirty-three surveys were received from residents; 21 tutors handed in 67 evaluation reports (average: 3 per tutor). They dealt with all the areas of competence, particularly those of communication, teaching, and ethics. Tasks most used were clinical sessions, critical incidents and video-recording. Both tutors and residents thought that the new method could be useful for reflecting on clinical practice, understanding their own areas of competence better and for strengthening the tutor-trainee relationship, especially if some suggestions to improve its practical use and reduce time and effort involved were taken into account. CONCLUSIONS The new STB in its current version or with some modifications is a useful tool for residents' training assessment and is probably accepted well in our ambit.

Abstract
Mutagenesis of Candida albicans strain ATCC 26555 with N-methyl-nitro-N-nitrosoguanidine followed by plating on solid yeast nitrogen base-N-acetylglucosamine medium at 37 degrees C yielded colony morphology variants that were characterized as forming smooth colonies, in contrast to the rough colonies formed by the parental strain. One yeast monomorphic mutant, CAL4, was studied in detail. Strain CAL4 is defective in filamentous growth, unable to form hyphae or pseudohyphae in vivo and in vitro. These filamentous structures are not elicited by commonly used external stimuli such as serum. The mutant had no obvious alterations in its mannan, glucan or chitin content. The total quantity of non-covalently linked wall proteins was reduced in the mutant strain, but the electrophoretic pattern shown by these proteins was identical to that of proteins from the parental strain. CAL4 showed major differences from the parental strain in its formation of covalently linked wall proteins. An important aspect of these differences lay in the practical absence of proteins recognized by two monoclonal antibodies, 1B12 and 3H8, which are considered valuable tools in the diagnosis of candidiasis in part because they normally react strongly with all strains. The C. albicans mutant, blocked in yeast-mycelium transition, was avirulent in a mouse model, although it was able to grow in animal tissues.

Abstract
We have analyzed the folding state of cytosolic proteins imported in vitro into lysosomes, using an approach originally developed by Eilers and Schatz, (Eilers, M., and Schatz, G. (1986) Nature 322, 228-232) to investigate protein import into mitochondria. The susceptibility toward proteases of mouse dihydrofolate reductase (DHFR), synthesized in a coupled transcription-translation system with rabbit reticulocytes, decreased in the presence of its substrate analogue, methotrexate. This analogue complexes with high affinity with the in vitro synthesized DHFR and locks it into a protease-resistant folded conformation. DHFR was taken up by freshly isolated rat liver lysosomes and methotrexate reduced this uptake by about 80%. A chimeric DHFR protein, which carries the N-terminal presequence of subunit 9 of ATP synthase preprotein from Neurospora crassa fused to its N terminus, was taken up by lysosomes more efficiently. Again, methotrexate abolished the lysosomal uptake of the fusion protein, which was partially restored by washing of methotrexate from DHFR or by adding together methotrexate and dihydrofolate, the natural substrate of DHFR. Immunoblot analysis with anti-DHFR of liver lysosomes and of other fractions, isolated from rats starved for 88 h and treated with lysosomal inhibitors, suggests that DHFR is degraded by chaperone-mediated autophagy. Competition with ribonuclease A and stimulation by ATP/Mg(2+) and the heat shock cognate protein of 73 kDa show that the lysosomal uptake of the fusion protein also occurs by this pathway. It is concluded that the lysosomal uptake of cytosolic proteins by chaperone-mediated autophagy mainly occurs by passage of the unfolded proteins through the lysosomal membrane. Therefore, this mechanism is different from protein transport into peroxisomes, but similar to the import of proteins into the endoplasmic reticulum and mitochondria.

Abstract
Echinococcus granulosus is the agent that causes the classical hydatidosis or cystic echinococcosis. The most spread cycle in South America is the sheep-dog cycle, and offers favorable conditions for the development of the parasite. As the province of La Pampa shows an endemic presence with notification of cases and infected dogs, the present work has the aim of contributing to the study of the distribution and prevalence of the disease in the district of Maracó, La Pampa, Argentina. Dogs of 36 farms that had ovines, were dosed with arecoline hydrobromide at a dose of 3.5 mg/kg. Dogs from 27 (75%) farms resulted positive to Tenia sp. and 3 (8.3%) to E. granulosus. Blood samples were taken to all the people living in all the inquired farm and were processed by the ELISA test for hydatidosis. A retrospective survey on cases of human hydatidosis attended in the Hospital of General Pico, head if the sanitary region, and in two private clinics was performed. Analysis of clinical records indicated 11 cases operated during the period 1996/1997 (annual incidence rate of 6.8 per 100,000 inhabitants). It is of public health interest to fulfill epidemiologic investigations in other districts of the Province of La Pampa with the aim of delimitating the endemic distribution within the province and also organizing surveillance systems on human hydatidosis.

Abstract
Urea or hot sodium dodecyl sulphate extracted a significant amount of the same proteins from the matrix of the cell wall of the yeast form and mycelial cells of Candida albicans. Gel filtration analysis of the urea-extracted proteins revealed that they occurred in the form of large complexes which were unaffected by up to 8 M urea. Among them, proteins en route to becoming covalently associated within the wall scaffold were identified by their reaction with specific antibodies. When urea was removed by dialysis, some of these proteins specifically reassociated into large aggregates which bound strongly with ConA, whereas others remained soluble in smaller associated products. The ability of some of these proteins to bind to the insoluble wall polysaccharides was also assessed. No self-assembling proteins were able to bind to glucans and/or chitin. Specificity of the binding to polysaccharides made of beta-bound glucosyl or N-acetylglucosaminyl residues was determined by the competitive effect of several disaccharides. Whereas laminaribiose and diacetylchitobiose were strong inhibitors of protein binding to both glucan and chitin, lactose, maltose and sucrose were ineffective.

Abstract
Cell wall regeneration of individual Candida albicans yeast and mycelial protoplasts was studied with confocal and electron microscopy using polyclonal antibodies and lectins. Quantitative measurements of the fluorescence emitted by individual protoplasts during the process of regeneration indicate that chitin is the first polymer to be laid down, whereas beta (1,3)- and beta (1,6)glucan are incorporated at a later stage. Mannoproteins were found on the surface of fresh protoplasts and those newly synthesized were then deposited with time. During the first steps of wall regeneration, the proteins that interacted covalently with chitin or glucan were different, but the same species were found linked to each polymer in yeast and mycelial regenerating forms. The aggregates formed by regenerating protoplasts were shown to be due to the chitin and mannoprotein network initially laid.

Abstract
OBJECTIVE To report on our experience with the EKL-Compact (Olympus) lithotriptor in the treatment of ureteral calculi. METHODS/RESULTS From December, 1994 to December, 1995, we performed 192 ureteroscopy procedures for endoscopic treatment of ureteral calculi. Stone removal was achieved without necessitating fragmentation in 131 cases. In the remaining cases, stone fragmentation with the EKL-Compact (Olympus) electrokinetic lithotriptor achieved a 95% success rate. CONCLUSION We have achieved a high success rate with the EKL-Compact lithotriptor. Its components are easily assembled, which facilitates sterilization and storage. It is compact and easily transportable.

Abstract
Candida albicans cell wall components were analyzed by ethylenediamine (EDA) treatment. Based on their different solubility properties, the cell wall components produced three fractions (A, B, and C). Fractions B (EDA-soluble, water-insoluble) and C (EDA-insoluble) contained glucan, chitin, and protein in different proportions. After zymolyase (mainly a beta-glucanase complex) or chitinase treatment of fractions B and C, more polysaccharides and proteins were solubilized by a second EDA treatment, suggesting that the solubility of the polymers in EDA depends on the degree of polymer interactions. Western blot analysis using two monoclonal antibodies (1B12 and 4C12) revealed electrophoretic patterns that were similar in mycelial and yeast morphologies, except that in material obtained from mycelial walls, an additional band was detected with MAb 1B12. Fluorescence microscopy of cell wall fractions treated with FITC-labeled Con-A, Calcofluor white, and FITC-labeled agglutinin showed that glucan and mannoproteins are uniformly distributed in fractions B and C, while chitin is restricted to distinct patches. Transmission electron microscopy demonstrated that fraction C maintained the original shape of the cells, with an irregular thickness generally wider than the walls. When fraction C was treated with chitinase, the morphology was still present and was maintained by an external glucan layer, with an internal expanded fibrillar material covering the entire cellular lumen. Degradation of the glucan skeleton of fraction C with zymolyase resulted in the loss of the morphology.

Abstract
Cytoskeletons provide valuable information on the composition and organization of the cell's contractile machinery, and in many cases these cell models retain the ability to contract. To quantitate contraction rates, we developed a novel stopped-flow assay permitting simultaneous analysis of thousands of Dictyostelium cytoskeletons within milliseconds of mixing with Mg-ATP. Cytoskeletons were placed in one syringe of the stopped flow apparatus and the appropriate buffer was placed in the second syringe. Mixing with Mg-ATP caused an immediate increase in the absorbance at 310 nm. Rapid fixation of the cytoskeletons during the reaction confirmed that this change in absorbance was highly correlated with contraction of the cytoskeletons. This spectroscopic change was used to measure the effects of temperature, pH, ionic strength, and nucleotides on contraction rate. Treatment with high salt and ATP removed most of the myosin, some actin, and small amounts of minor proteins. These extracted cytoskeletons lost the ability to contract, but after the addition of purified Dictyostelium myosin they regained full function. In contrast, rabbit skeletal muscle myosin was unable to restore contractility, even though it bound to the extracted cytoskeletons. Cytoskeletons prepared from a myosin-null mutant did not contract. Upon the addition of purified ameba myosin, however, they became contractile. These results suggest that filamentous Dictyostelium myosin II is essential for contraction, and that the actin cytoskeleton and associated proteins retain their functional organization in the absence of myosin.

Abstract
We interviewed 219 patients with a questionnaire to evaluate the prevalence of insomnia, and to assess whether benzodiazepine therapy was correctly indicated. Insomnia was present in 86 patients (39%), being initial in more than one half. Thirty-two of the patients with insomnia were receiving benzodiazepines (37%), 24 of whom (75%) had been treated for more than one year. The drug was incorrectly indicated in 18 (56%), in most cases because it was inappropriate for the type of the patient's insomnia. In six of these patients (33%), incorrect indication was related with self-medication. The benzodiazepine was incorrectly indicated in all the patients with diurnal oversedation. We emphasize the frequency of incorrect indications of these drugs, and we insist on the need that general practitioners have of a better knowledge of the pharmacokinetics of each drug, which is the basis for a correct indication.

Abstract
Red-cell deformability was assessed with the Hanss' haemorheometer in 63 carriers of the thalassaemic trait (20 beta and 43 delta beta). Impaired deformability (rigidity index 10.5 +/- 1.4) was present in 80% of the carriers of both beta- and delta beta-traits, as compared with a control group (rigidity index 8.7 +/- 0.6). No correlation was found between such indices and several parameters capable of influencing upon red-cell deformability, namely, MCV, MCH, RDW and MDA. The possibility of any impairment of lipid compounds in red cell membrane is suggested as a cause of decreased deformability in thalassaemia carriers.
