Abstract
BACKGROUND In recent years, remarkable improvements in our understanding of atopic dermatitis (AD) have revolutionized treatment perspectives, but access to reliable data from clinical practice is essential. MATERIALS AND METHOD The Spanish Atopic Dermatitis Registry, BIOBADATOP, is a prospective, multicenter database that collects information on patients of all ages with AD requiring systemic therapy with conventional or novel drugs. We analyzed the registry to describe patient characteristics, diagnoses, treatments, and adverse events (AEs). RESULTS We studied data entries for 258 patients who had received 347 systemic treatments for AD. Treatment was discontinued in 29.4% of cases, mostly due to a lack of effectiveness (in 10.7% of cases). A total of 132 AEs were described during follow-up. Eighty-six AEs (65%) were linked to a systemic treatment, most commonly dupilumab (39 AEs) and cyclosporine (38 AEs). The most common AEs were conjunctivitis (11 patients), headache (6), hypertrichosis (5), and nausea (4). There was 1 severe AE (acute mastoiditis) associated with cyclosporine. CONCLUSIONS Initial findings on AEs from the Spanish BIOBADATOP registry are limited by short follow-up times precluding comparisons or calculation of crude and adjusted incidence rates. At the time of our analysis, no severe AEs had been reported for novel systemic therapies. BIOBADATOP will help answer questions on the effectiveness and safety of conventional and novel systemic therapies in AD.

Abstract
Ammonia (NH3) emissions are linked to eutrophication, plant toxicity and ecosystem shifts from N to P limitation. Bryophytes are key components of terrestrial ecosystems, yet highly sensitive to N deposition. Hence, physiological responses of mosses may be indicative of NH3-related impacts, and thus useful to foresee future ecosystem damages and establish atmospheric Critical Levels (CLEs). In this work, samples of Hypnum cupressiforme Hedw. were seasonally collected along a well-defined NH3 concentration gradient in an oak woodland during a one-year period. We performed a comprehensive evaluation of tissue chemistry, stoichiometry, metabolic enzymes, antioxidant response, membrane damages, photosynthetic pigments, soluble protein content and N and C isotopic fractionation. Our results showed that all the physiological parameters studied (except P, K, Ca and C) responded to the NH3 gradient in predictable ways, although the magnitude and significance of the response were dependent on the sampling season, especially for enzymatic activities and pigments content. Nutritional imbalances, membrane damages and disturbance of cellular C and N metabolism were found as a consequence to NH3 exposure, being more affected the mosses more exposed to the barn atmosphere. These findings suggested significant implications of intensive farming for the correct functioning of oak woodlands and highlighted the importance of seasonal dynamics in the study of key physiological processes related to photosynthesis, mosses nutrition and responses to oxidative stress. Finally, tissue N showed the greatest potential for the identification of NH3-related ecological end points (estimated CLE=3.5μgm-3), whereas highly scattered physiological responses, although highly sensitive, were not suitable to that end.

Abstract
Rift Valley fever (RVF) is a mosquito-borne disease caused by the Rift Valley fever virus (RVFV). Rift Valley fever affects a large number of species, including human, and has severe impact on public health and the economy, especially in African countries. The present study examined the vector competence of three different European mosquito species, Culex pipiens (Linnaeus, 1758) form molestus (Diptera: Culicidae), Culex pipiens hybrid form and Stegomyia albopicta (= Aedes albopictus) (Skuse, 1894) (Diptera: Culicidae). Mosquitoes were artificially fed with blood containing RVFV. Infection, disseminated infection and transmission efficiency were evaluated. This is the first study to assess the transmission efficiency of European mosquito species using a virulent RVFV strain. The virus disseminated in Cx. pipiens hybrid form and in S. albopicta. Moreover, infectious viral particles were isolated from saliva of both species, showing their RVFV transmission capacity. The presence of competent Cx. pipiens and S. albopicta in Spain indicates that an autochthonous outbreak of RVF may occur if the virus is introduced. These findings provide information that will help health authorities to set up efficient entomological surveillance and RVFV vector control programmes.

Abstract
The emerging disease West Nile fever is caused by West Nile virus (WNV), one of the most widespread arboviruses. This study represents the first test of the vectorial competence of European Culex pipiens Linnaeus 1758 and Stegomyia albopicta (= Aedes albopictus) (both: Diptera: Culicidae) populations for lineage 1 and 2 WNV isolated in Europe. Culex pipiens and S. albopicta populations were susceptible to WNV infection, had disseminated infection, and were capable of transmitting both WNV lineages. This is the first WNV competence assay to maintain mosquito specimens under environmental conditions mimicking the field (day/night) conditions associated with the period of maximum expected WNV activity. The importance of environmental conditions is discussed and the issue of how previous experiments conducted in fixed high temperatures may have overestimated WNV vector competence results with respect to natural environmental conditions is analysed. The information presented should be useful to policymakers and public health authorities for establishing effective WNV surveillance and vector control programmes. This would improve preparedness to prevent future outbreaks.

Abstract
Deposition of dissolved organic nitrogen (DON) in both bulk precipitation (BD) and canopy throughfall (TF) has been measured for the first time in the western Mediterranean. The study was carried out over a year from 2012 to 2013 at four evergreen holm oak forests located in the Iberian Peninsula: two sites in the Province of Barcelona (Northeastern Spain), one in the Province of Madrid (central Spain) and the fourth in the Province of Navarra (Northern Spain). In BD the annual volume weighted mean (VWM) concentration of DON ranged from 0.25 mg l(-1) in Madrid to 1.14 mg l(-1) in Navarra, whereas in TF it ranged from 0.93 mg l(-1) in Barcelona to 1.98 mg l(-1) in Madrid. The contribution of DON to total nitrogen deposition varied from 34% to 56% in BD in Barcelona and Navarra respectively, and from 38% in Barcelona to 72% in Madrid in TF. Agricultural activities and pollutants generated in metropolitan areas were identified as potential anthropogenic sources of DON at the study sites. Moreover, canopy uptake of DON in Navarra was found in spring and autumn, showing that organic nitrogen may be a supplementary nutrient for Mediterranean forests, assuming that a portion of the nitrogen taken up is assimilated during biologically active periods.

Abstract
OBJECTIVE To apply new mathematical models according to Non Muscle Invasive Bladder Carcinoma (NMIBC) biological characteristics and enabling an accurate risk estimation of multiple recurrences and tumor progression. The classical Cox model is not valid for the assessment of this kind of events becausethe time betweenrecurrencesin the same patientmay be stronglycorrelated. These new models for risk estimation of recurrence/progression lead to individualized monitoring and treatment plan. MATERIALS AND METHODS 960 patients with primary NMIBC were enrolled. The median follow-up was 48.1 (3-160) months. Results obtained were validated in 240 patients from other center. Transurethral resection of the bladder (TURB) and random bladder biopsy were performed. Subsequently, adjuvant localized chemotherapy was performed. The variables analyzed were: number and tumor size, age, chemotherapy and histopathology. The endpoints were time to recurrence and time to progression. Cox model and its extensions were used as joint frailty model for multiple recurrence and progression. Model accuracy was calculated using Harrell's concordance index (c-index). RESULTS 468 (48.8%) patients developed at least one tumor recurrence and tumor progression was reported in 52 (5.4%) patients. Variables for multiple-recurrence risk are: age, grade, number, size, treatment and the number of prior recurrences. All these together with age, stage and grade are the variables for progression risk. Concordance index was 0.64 and 0.85 for multiple recurrence and progression respectively. CONCLUSION the high concordance reported besides to the validation process in external source, allow accurate multi-recurrence/progression risk estimation. As consequence, it is possible to schedule a follow-up and treatment individualized plan in new and recurrent NMCB cases.

Abstract
It was designed and constructed a new thermogravitational column able to operate at high pressures (up to 50 MPa). This new thermogravitational column is of the cylindrical type with closed ends. It is made of stainless steel. The length of the column is 0.5 m and the gap between its two walls is variable. First, the column was validated at atmospheric pressure by means of measurements of the thermodiffusion coefficient of well-known binary mixtures. Then, this new thermogravitational column was used to measure the thermodiffusion coefficient of the binary mixtures 1,2,3,4-tetrahydronaphtalene/isobutylbenzene, 1,2,3,4-tetrahydronaphtalene/n-dodecane, and isobutylbenzene/n-dodecane at high pressures and within the pressure range between 0.1 and 20 MPa at a mean temperature of 25 °C. We have found a linear dependence between the thermodiffusion coefficient and the pressure.

Abstract
PRAME is a tumor associated antigen (TAA) of particular interest since it is widely expressed by lymphoid and myeloid malignancies. Several studies have associated high PRAME RNA levels with good prognosis in acute myeloid leukemia (AML). PRAME expression is regulated at the epigenetic level. For this reason inhibitors of DNA methylation, such as 5-azacytidine, can modulate the expression of this TAAs. In the current study we analyzed the effect of 5-azaC on the expression of PRAME in blasts versus CD34+ cells from healthy donors in an attempt to increase its expression, thus inducing a potential target for therapeutic strategies.

Abstract
The frequencies of human leukocyte antigen (HLA) class I and class II specificities and haplotypic associations were determined in 1940 unrelated donors from Castilla y León and compared with other Iberian, Mediterranean and European populations. Specificities were determined using polymerase chain reaction reverse sequence-specific oligonucleotide or polymerase chain reaction sequence-specific primer techniques. In the analysis, 19, 29 and 13 specificities were found for HLA-A, -B and -DRB1, respectively, with HLA-A*02 (26%), -A*01 (11%), -B*44 (16%), -B*35 (10%), -DRB1*07 (16%) and -DRB1*13 (14%) showing the highest frequencies. In addition, 10 common HLA-A-B-DRB1 haplotypic associations were observed, A*01-B*08-DRB1*03 (3%) and A*29-B*44-DRB1*07 (3%) being the most frequent ones. These findings indicate that the population of Castilla y León is genetically equidistant from the Portuguese and other Spanish populations and shares a common origin with other Iberian populations, in which European, Mediterranean and North African genetic components are present; this is in agreement with the historical and genetic background of the population. These data contribute to a better understanding of the genetic structure of the Iberian Peninsula and provide a healthy control population from our region that should be useful for the study of disease associations.

Abstract
When nonliving cells of Schizosaccharomyces pombe were subjected to the action of alternating uniform and nonuniform electric fields, two types of orientation were produced. The first one, with its longest axis parallel to the field lines, is similar to that obtained with living cells. The second, perpendicular to the direction of the field, is produced for relatively high frequencies and low conductivities; this probably takes place when the conductivities of the external and internal media (cell cytoplasm) become equal. A mixed cell population is produced in a discrete interval of the parameters used. Our results provide direct evidence that cell alignment does not depend on the physiological state of the cells.

Abstract
The physical and biological parameters involved in efficient transformation of Kluyveromyces lactis by electroporation have been analyzed. By using an optimum voltage and a constant volume of cell suspension in a cuvette, the efficiency of transformation increased with increases in cell numbers and plasmid concentration. However, the most important parameter was the time of the pulse. Changes of 1 ms decreased the efficiency of transformation more than 70 to 80%. Under our best conditions, between 10 and 10 transformants per mug of plasmid DNA could be obtained. Under certain conditions, the size of the plasmid also affected electroporation efficiency. In any case, we did not obtain integrative transformation with an autonomously replicating plasmid.

Abstract
INTRODUCTION A large amount of current schizophrenia research has been centered on the understanding of its etiological mechanisms and the detection of vulnerability markers in people at risk. This vulnerability called schizotypy can be identified in people not affected by the illness at the clinical level. AIM To check if the schizotypic personality disorder as a vulnerability marker of the disorders in the schizophrenic spectrum predicts the presence of psychopathologic symptoms and alcohol and drugs intake. SUBJECTS AND METHODS From a population of 442 university students tested with the Schizotypy Personality Questionnaire (SPQ), it was selected a sample including people scoring on the 20% superior and inferior for the characteristic factors of schizophrenia corresponding to positive symptoms (cognitive-perceptual), negative symptoms (interpersonal) and thought disorder (disorganized). Furthermore, it was evaluated the presence of psychopathological problems and symptoms. Also, the participants gave information about alcohol and drugs intake as a passive coping strategy with stress. RESULTS Compared with the low scored, subjects with high scores in the schizotypic personality disorder showed a significant increase in the presence of psychopathological problems and symptoms and a higher alcohol and drugs intake. That occurs mainly when those scores are found in symptoms associated to thought disorder and negative symptoms as lack of interest in social activities and emotional flattening. CONCLUSIONS The schizotypic personality disorder, in accordance with its role as vulnerability factor, seems to co-occur with a higher volume of somatic and psychopathologic symptoms, and alcohol and drugs intake.

Abstract
INTRODUCTION The Spanish Society of Nephrology "Quality in Nephrology Working Group" (QNWG) was created in 2002. The aims of this group are the identification, diffusion, implementation and consolidation of a systematic, objective and comprehensive set of quality performance measures (QPMs) to help along the improvement of patient care and outcomes on hemodialysis, by means of strategies of feedback and benchmarking, and the design of quality improvement projects. The objective of this study is to present the preliminary results of a set of quality performance measures obtained in a group of Spanish hemodialysis centers, as well as to evaluate the repercussion of the application of the aforementioned thecniques on the observed results. METHODS During 2007 a total of 28 hemodialysis units participated in the study; 2516 patients were evaluated. A specific software was designed and used to facilitate the calculation of CPMs in each unit. The clinical indicators used refered to dialysis adequacy; anemia; mineral metabolisme; nutrition; viral infections; vascular access; mortality, morbidity (number and days of hospital admissions); and renal transplant. Every three months each center received its own data and its comparison with the rest of the group. RESULTS Except for hemoglobin levels we observed a global improvement. The percentage of centers reaching the stablished standards defined by the QNWG passed from 65% to 90,9% for Kt/V Daugirdas II (> 1,3 in > that 80% of the patients); from 71,4 % to 77,2 % for PTH (> 30 % of patients with serum PTH between 150 and 300 pg/ml); and from 42,8 % to 63,5 % for phosphate (> 75 % of patients with a serum phsphate < 5,5 mg/dl). More than 50% of centers showed an improvement in their final results as compared with their own initial results in all analyzed CPMs. Those centers that did not obtained an improvement in their results started the study with better percentages of acomplishment than those that showed a significant improvement in QPMs. (80,6+/-15,4 versus 71,8+/-16,6 respectively; p<0,001) CONCLUSIONS We are starting to make progresses in our knowledge of clinical results in our hemodialysis units, although there is still a long way to go over. To monitor and share CPMs results within hemodialysis centers might help to improve their results as well as to reduce intecenters variability.

Abstract
Hemodialysis shows an increased prevalence in elderly patients, a population which often presents poor nutrition, high prevalence of cardiovascular, neurological and osteoarticular diseases and psycho-social problems. The objective of this epidemiological, cross-sectional and multicenter study, in patients older than 65 years (n 625) and >75 years (n 558) from 29 Spanish medical institutions was to perform an epidemiological analysis It included demographic information, as well as data regarding chronic renal failure, functional and psychological abilities (Katz Index, Lawton and Karnofsky Scales), dialysis logistics and clinical parameters. The study analyzed data from 1,183 patients (678 female), mean age 75.4+/-5.5 years; mean duration of dialysis 4.3+/-5.1 years (57.7% were referred by the GP: general practitioner). The most frequent etiologies were diabetic nephropathy (21.2%) and vascular renal disease (20.9%). The main comorbilites were high blood pressure (75.6%), Diabetes Mellitus (32.9%) and vascular (29.0%) and osteoarticular (27.3%) diseases. The great majority of patients lived at their family home (85.0%), travelled to their dialysis units alone (80.8%) and by ambulance (56.7%), and it took them less than an hour to arrive (87.5%). Over 75% of patients were fully functional (79.4% under 75 years and 71.6% over 75); meanwhile 10.5% were partially impaired and 13,8% severely impaired. Karnofsky performance scale scored less than 70 in 59.4% of the patients. Analytical parameters rated Hb >or= 11 g/dL for 81.7% of patients; ferritin >or= 100 ng/dL for 98.5%; PTH 150-300 pg/mL for 31.9%; albumin >3.5 g/dL for 75.6%; and serum phosphor <5.5 mg/dL for 70.6%. For the dialysis Kt/V the mean value was 1.4+/-0.3 with a mean duration of dialysis session of 11.7+/-4.0 hours/week. High permeability membranes were used in 52.3% of patients and internal arteriovenous fistula in 74.0%. Around 75% of elderly patients on hemodialysis fulfill age-suitable daily living activities and display adequate dialysis quality parameters.

Abstract
Complexing capacity of naturally occurring ligands in Vitis vinifera (Tempranillo variety) wines has been studied with respect to two target metals (Cu and Zn) by differential pulse anodic stripping voltammetry (DPASV). Eight commercial wines of two certified brands of origin (CBO) and a young wine along its vinification process were monitored. Conditional stability constants and total complexing ligand(s) concentration(s) have been calculated for both metals. Discussion of the particular electrochemical responses for Cu and Zn for all samples is presented. A follow-up of the Cu stripping response allowed differentiating a commercial wine from one under processing related to the cupric casse phenomenon. Interaction of Cu with two molecular forms of cyanidin has been theoretically modeled at natural wine pH.

Abstract
Several isolates were obtained from sporocarps of Amanita caesarea (Scop.: Fr.) Pers. associated with Quercus suber and Castanea sativa coming from the southwest of Spain. Culture conditions were optimized for these isolates. The largest radial growth was obtained at pH 6-7, and optimal growth temperature was 24-28 degrees C depending on the isolate. Albumin bovine and nitrate produced the largest patch size diameters, but the greatest mycelium dry weight yields were obtained with ammonium. Mannitol produced the largest radial growth, and mannitol and glucose yielded the biggest mycelium dry weights. Although variations in growth behaviour between isolates were observed, only one internal spacer sequence-restriction fragment length polymorphism type was obtained.

Abstract
We have analysed 198 fast-growing soybean-nodulating rhizobial strains from four different regions of China for the following characteristics: generation time; number of plasmids; lipopolysaccharide (LPS), nodulation factors (LCOs) and PCR profiles; acidification of growth medium; capacity to grow at acid, neutral, and alkaline pH; growth on LC medium; growth at 28 and 37 degrees C; melanin production capacity; Congo red absorption and symbiotic characteristics. These unbiased analyses of a total subset of strains isolated from specific soybean-cropping areas (an approach which could be called "strainomics") can be used to answer various biological questions. We illustrate this by a comparison of the molecular characteristics of five strains with interesting symbiotic properties. From this comparison we conclude, for instance, that differences in the efficiency of nitrogen fixation or competitiveness for nodulation of these strains are not apparently related to differences in Nod factor structure.

Abstract
Biodiversity studies of native soybean-nodulating rhizobia in soils from the Chinese Hubei province (Honghu county; pH 8, alluvial soil) have been carried out. Inoculation of an American (Williams) and an Asiatic (Peking) soybean cultivar with eleven soil samples led to the isolation of 167 rhizobia strains. The ratio (%) of slow-/fast-growing isolates was different depending on the trap plant used. All isolates were able to nodulate both cultivars, although the N2-fixation efficiency (measured as plant-top dry weight) was different among them. A total of thirty-three isolates were selected for further characterisation on the basis of physiological parameters, PCR-RFLP of symbiotic genes and Low Molecular Weight RNA, lipopolysaccharide, protein and plasmid profiles. Low Molecular Weight RNA profiling indicates that all the isolates belong to species Sinorhizobium fredii. The dendrogram obtained with the physiological parameters has been useful to classify the isolates at strain level, although plasmid profiling was the most discriminating technique to detect differences among the analysed soybean-rhizobia isolates, showing there is not two isolates identical each other. Plasmid profile analyses also revealed that some of the investigated strains contain low molecular weight plasmids (7-8-kb). They are, to our knowledge, the smallest ever found in rhizobia and they could be the starting point for the construction of the first group of vectors based on a native rhizobia replicon.

Abstract
The effect of a variety factors on the survival of several rhizobia strains on inoculants and inoculated seeds has been evaluated. Since the rhizobia strains showed different cell-density-evolution patterns on peat-based inoculants and on inoculated seeds, several inoculant formulations with highly effective Rhizobium/Bradyrhizobium strains (for Lupinus, Hedysarum, Phaseolus and Glycine max.) were monitored under the following storage conditions: (a) the inoculants were kept refrigerated (at 4 degrees C), or (b) at room temperature (25 degrees C). The effect of water content (30-50%, w/w) in the inoculants as well as that of several seed-coating adhesives were also investigated. Alternative carriers including perlite and vermiculite were tested. For all of the strains, survival on sterile peat-based inoculants was higher than on the corresponding unsterile peat formulation; for the latter, refrigerated storage conditions are recommended to ensure high bacterial densities. The water content of the inoculants had a differential effect on strain survival depending on the sterility of the peat, such that a high water content was more detrimental when unsterilized peat was employed. The best adherent for rhizobia survival was a gum arabic/water solution. Perlite was as effective as peat in maintaining a high population of rhizobia, at least for 6 months of storage.

Abstract
The strain Bacillus sp. CECT 450 increased nodulation on bean (Phaseolus vulgaris L.) when co-inoculated with Rhizobium tropici CIAT 899. This positive effect occured under controlled conditions on perlite-vermiculite, sand, or in a mixture of soil and sand. This increase was also observed in a field assay. Nodulation kinetic studies suggested that the synergistic effect is pronounced during the latter stages of cultivation. In contrast, the same bacteria co-inoculated with Bradyrhizobium japonicum USDA 110 reduced nodulation on soybean (Glycine max (L.) Merr.). Inoculation with Bacillus sp. CECT 450 alone had no effect on bean plants, but reduced root growth in soybean. The survival of Bacillus sp. CECT 450 on inoculated seeds was high, even when inoculated seeds were maintained for several months at room temperature.

Abstract
Quantitative analyses of fast- and slow-growing soybean rhizobia populations in soils of four different provinces of China (Hubei, Shan Dong, Henan, and Xinjiang) have been carried out using the most probable number technique (MPN). All soils contained fast- (FSR) and slow-growing (SSR) soybean rhizobia. Asiatic and American soybean cultivars grown at acid, neutral and alkaline pH were used as trapping hosts for FSR and SSR strains. The estimated total indigenous soybean-rhizobia populations of the Xinjiang and Shan Dong soil samples greatly varied with the different soybean cultivars used. The soybean cultivar and the pH at which plants were grown also showed clear effects on the FSR/SSR rations isolated from nodules. Results of competition experiments between FSR and SSR strains supported the importance of the soybean cultivar and the pH on the outcome of competition for nodulation between FSR and SSR strains. In general, nodule occupancy by FSRs significantly increased at alkaline pH. Bacterial isolates from soybean cultivar Jing Dou 19 inoculated with Xinjiang soil nodulate cultivars Heinong 33 and Williams very poorly. Plasmid and lipopolysaccharide (LPS) profiles and PCR-RAPD analyses showed that cultivar Jing Dou 19 had trapped a diversity of FSR strains. Most of the isolates from soybean cultivar Heinong 33 inoculated with Xinjiang soil were able to nodulate Heinong 33 and Williams showed very similar, or identical, plasmid, LPS and PCR-RAPD profiles. All the strains isolated from Xinjiang province, regardless of the soybean cultivar used for trapping, showed similar nodulation factor (LCO) profiles as judged by thin layer chromatographic analyses. These results indicate that the existence of soybean rhizobia sub-populations showing marked cultivar specificity, can affect the estimation of total soybean rhizobia populations indigenous to the soil, and can also affect the diversity of soybean rhizobial strains isolated from soybean nodules.

Abstract
1,2,3,4-Tetramethyl-5-(trifluoromethyl)cyclopentadiene (Cp*CF3-H, 1) reacts with [Ti(NMe2)4] (2) under mild conditions to give [Ti(mu-NMe2)(NMe2)(mu-F)(F)]6 (3) in nearly quantitative yield. The molecular structure of 3 consists of a ring of six [TiF2(NMe2)2] edge-bridged octahedra. Titanium complexes containing the Cp*CF3 ligand, which was the primary intention of these investigations, were not observed. C5Me4=C(NMe2)2 (4) was isolated as a by-product. The complete defluorination of an aliphatic CF3 group occurs during the reaction. The reaction mechanism involves the primary formation of a difluorofulvene intermediate C5Me4=CF2 (5), which was monitored by NMR studies. Density functional theory calculations predict a highly charged C6 atom (+0.87) in 5, which is discussed as the driving force of the reaction.

Abstract
We isolated a Tn5-induced Rhizobium tropici mutant that has enhanced capacity to oxidize N,N-dimethyl-p-phenylendiamine (DMPD) and therefore has enhanced respiration via cytochrome oxidase. The mutant had increased levels of the cytochromes c(1) and CycM and a small increase in the amount of cytochrome aa(3). In plant tests, the mutant increased the dry weight of Phaseolus vulgaris plants by 20 to 38% compared with the control strain, thus showing significantly enhanced symbiotic performance. The predicted product of the mutated gene is homologous to glycogen synthases from several bacteria, and the mutant lacked glycogen. The DNA sequence of the adjacent gene region revealed six genes predicted to encode products homologous to the following gene products from Escherichia coli: glycogen phosphorylase (glgP), glycogen branching enzyme (glgB), ADP glucose pyrophosphorylase (glgC), glycogen synthase (glgA), phosphoglucomutase (pgm), and glycogen debranching enzyme (glgX). All six genes are transcribed in the same direction, and analysis with lacZ gene fusions suggests that the first five genes are organized in one operon, although pgm appears to have an additional promoter; glgX is transcribed independently. Surprisingly, the glgA mutant had decreased levels of high-molecular-weight exopolysaccharide after growth on glucose, but levels were normal after growth on galactose. A deletion mutant was constructed in order to generate a nonpolar mutation in glgA. This mutant had a phenotype similar to that of the Tn5 mutant, indicating that the enhanced respiration and symbiotic nitrogen fixation and decreased exopolysaccharide were due to mutation of glgA and not to a polar effect on a downstream gene.

Abstract
INTRODUCTION The bipolar disorder is an important health problem. It presents with severe sintoms, and it tends to cronify. Although lithium has a prophilactic role, it has not controlled the development of severe psychosocial complications. It is necessary to study the psychosocial aspects related to this disorder, to define the areas in which the psychosocial interventions are needed, and the types of psychosocial approaches that can be useful. METHODS Review of the literature, through MEDLINE database in the last fifteen years, about psychosocial complications of bipolar disorder and its treatment. RESULTS Many articles emphasize the important psychosocial deficits that appear in patients with bipolar disorder. These deficits concern to all social functions and persist for a long time. The patients are more vulnerable to stressing events, that can have devastating consecuences. The articles report the influence in the evolution and prognosis of this disorder, by the comorbidity of other medical and pschiatric problems. The psychotherapeutical interventions can be of interest to treat the social aspects that lithium fails to control. CONCLUSIONS Our approach would tend to integrate in the clinical practice both, the biomedical and psychosocial theories. This permits an integral treatment of all the factors implicated in the genesis, maintenance, and consecuences of the mental disorders.

Abstract
Mental models constitute an alternative to the rule-based systems in the explanation of human reasoning (Johnson-Laird, 1983). In this paper, we claim that the concept of believability generally used to categorize content and context effects is of little use within a semantic theory. Thus, we propose the use of categories that are directly extracted from subjective relations among concepts within the reasoning problem. We demonstrate that manipulations based on this kind of categorization produce predictable patterns of responses in reasoning problems. We present two experiments to test our predictions, using conditional and syllogistic reasoning problems, and in both cases, we demonstrate the influence of conceptual knowledge not only in natural contexts, but also in experimentally created artificial contexts.

Abstract
Using the experimental data obtained with killed cells of Schizosaccharomyces pombe (1), we have formulated a theoretical model that is able to predict cell orientation for microorganisms with ellipsoidal or cylindrical shapes as a function of the frequency of the electric field and of the conductivity of the external medium. In this model, comparison of the difference in potential energy for both orientations parallel-perpendicular with the thermal agitation energy allows one to interpret the intervals where these orientations occur. The model implies that the conductivity of the cytoplasm is slightly higher than that of the external medium. This assumption is easy to understand taking into account that not all the intracytoplasmic material is released to the exterior during cell death.

Abstract
This report presents qualitative data of the effects of a free radical generator (benzyl viologen) on rat liver. Rats were administered benzyl viologen (0.825 mg per kg of body weight) or saline solution (controls) intraperitoneally, in single daily dosage for 15 days. For microscopic examination animals were killed after 3 or 15 days of treatment. In the control animals, liver ultrastructure remained normal throughout the experiment. But in rats with benzyl viologen it was possible to observe important morphological alterations essentially in mitochondria, frequently forming ring-like bodies. Endoplasmic reticulum was observed as concentric patterns which cover the mitochondria and, on occasion, the lipid droplets within the cell. Increased number of dense granular lysosomes were observed in the apical cytoplasm mainly close to the bile canaliculus. A large quantity of lipid inclusions and cellular degeneration of the liver of treated rats showed a marked dose-response relationship.

Abstract
Saccharomyces cerevisiae showed different dielectrophoretic behavior depending on the source of carbon for growth. Growth on fermentable carbon sources produced a dielectrophoretic response that decreased according to the amount of sugar present in the culture medium. Growth on nonfermentable carbon sources produced a constant dielectrophoretic yield, independent of the amount and source of carbon present in the medium. The dielectrophoretic yield, however, was independent of the nitrogen source. The yield spectrum for S. cerevisiae protoplasts was similar to that for the cells, although a decrease in the absolute value was observed. This decrease could be explained by the reduction in cell size and by assuming that the cell wall contributes a negative net charge to the yield. Fungal spores responded to the nonuniform electric field in the same range of frequencies as assayed for yeast cells.

Abstract
The dielectrophoretic behaviour of yeast cells dividing by budding or by transversal fission was analyzed. The results obtained show that the dielectrophoretic yield is a linear function of alternating voltage, cell concentration and the square root of the time of collection in all the species assayed. Dependence of the rate of collection on the frequency of the voltage applied (between 0.2 and 5 MHz) was also found. This behaviour is similar in the three microorganisms studied. The scale factor correlating the frequency spectrum for Saccharomyces cerevisiae and Saccharomycopsis lipolytica is proportional to cell size. However, these results can not be extended to Schizosaccharomyces pombe. A relationship between the dielectrophoretic yield and the age of the culture and the consumption of glucose has been established for the three yeast strains. Dielectrophoresis also permits the differentiation between viable and non-viable cells.
