Abstract
Non-Abelian gauge theories underlie our understanding of fundamental forces in nature, and developing tailored quantum hardware and algorithms to simulate them is an outstanding challenge in the rapidly evolving field of quantum simulation. Here we take an approach where gauge fields, discretized in spacetime, are represented by qudits and are time evolved in Trotter steps with multiqudit quantum gates. This maps naturally and hardware efficiently to an architecture based on Rydberg tweezer arrays, where long-lived internal atomic states represent qudits, and the required quantum gates are performed as holonomic operations supported by a Rydberg blockade mechanism. We illustrate our proposal for a minimal digitization of SU(2) gauge fields, demonstrating a significant reduction in circuit depth and gate errors in comparison to a traditional qubit-based approach, which puts simulations of non-Abelian gauge theories within reach of NISQ devices.

Abstract
A 78-year-old Caucasian male presented with diplopia and decreased vision in the left eye for 1 month, in addition to a painless fleshy lesion in the inner corner of the left eye for 3-month duration. His best-corrected visual acuity was 20/40 and 20/50. Slit lamp examination revealed a left medial conjunctival and caruncular lesion, measuring 6 mm by 4 mm. Histology of the excised mass showed a cellular submucosal spindle cell neoplasm without cytologic atypia and rare mitoses, immunohistologically diffusely positive for CD34 and STAT6, and negative for SMA. Based on these findings, solitary fibrous tumor was diagnosed. With the combined diagnostic power of light microscopy and immunohistochemistry, SFTs are diagnosed increasingly and more accurately in the orbit. With this first case report of a caruncular SFT, we believe that SFTs should remain on the differential for mesenchymal tumors of the conjunctiva and caruncle.

Abstract
AIMS The aim of this study was to report the predictors and clinical impact of transcatheter heart valve (THV) thrombosis in patients undergoing transcatheter mitral valve implantation (TMVI). METHODS AND RESULTS We included 130 patients who consecutively underwent TMVI. Transoesophageal echocardiography (TOE) and/or computed tomography (CT) were performed in 91.7% of patients at discharge, in 73.3% at three months and in 72% beyond three months. THV thrombosis was defined as the presence of at least one thickened leaflet with restricted motion confirmed by TOE or contrast CT and classified as immediate, early, or late according to the timing of diagnosis. THV thrombosis was observed in 16 (12.3%) patients: immediate in 43.7%, early in 37.5% and late in 18.8%. Most of these thromboses were subclinical (93.7%) and non-obstructive (87.5%). No thromboembolic event occurred. After optimisation of antithrombotic treatment, THV thromboses resolved in all but one patient. Predictors were shock for immediate (p<0.001), male sex for early (p=0.045) and absence of anticoagulation for both early (p=0.018) and late (p=0.023) THV thromboses. CONCLUSIONS THV thrombosis is frequent after TMVI, occurs mainly within the first three months, is mostly subclinical and resolves after optimisation of antithrombotic treatment. An anticoagulation therapy for at least three months after the procedure is mandatory.

Abstract
Abstract
Objective
To provide norms applicable to Spanish-speakers living in the US- Mexico border region for the Halstead Category Test, a test of executive function.
Participants and Method
Healthy Spanish-speakers (n = 252) were recruited from the US–Mexico border regions (Age: M = 37.3, SD = 10.2, range 19-60; Education: M = 10.7, SD = 4.3, range 0-20; 58% female). Participants completed the Category Test as part of a larger neuropsychological test battery. Relationships between demographic variables and raw error scores were assessed using Spearman and Wilcoxon Rank-sum tests. Demographically corrected T-scores for the Category Test were normed using fractional polynomial equations accounting for age, education, and sex. For comparison, T-scores were also computed for the Spanish-speaking normative sample using published norms for English-speaking non-Hispanic Whites and African Americans, which were also adjusted for age, education and sex. Impairment rates based on -1SD (T < 40) were calculated using both, published and current, norms.
Results
Older age was significantly associated with higher number of errors (Spearman ρ = 0.32, p < .001) and higher education was associated with lower number of errors (Spearman ρ = -0.52, p < .001), with no other significant demographic effects. Applying non-Hispanic norms resulted in overestimation of impairment rates in the Spanish-speaking sample (impairment rate: 48% with White norms and 27% with African American norms). This pattern was evident across levels of education except in participants with 13+ years of education, where rates of impairment using African American norms were comparable to those based on the newly developed norms.
Conclusions
The present study is the first to develop norms for the Category test in a sample of Spanish-speakers in the US-Mexico border region. These norms will provide tools for the assessment of executive function in this population. Research concerning generalizability of norms to other Spanish-speaking populations is needed.

Abstract
Although Heat Waves (HWs) are expected to increase due to global warming, they are a regional phenomenon that demands for local analyses. In this paper, we assess four HW metrics (HW duration, HW frequency, HW amplitude, and number of HWs per season) as well as the share of extremely warm days (TX95, according to the 95th percentile) in South America (SA). Our analysis included observations as well as simulations from global and regional models. In particular, Regional Climate Models (RCMs) from the Coordinated Regional Climate Downscaling Experiment (CORDEX), and Global Climate Models (GCMs) from the Coupled Model Intercomparison Project Phase 5 (CMIP5) were used to project both TX95 estimates and HW metrics according to two representative concentration pathways (RCP4.5 and RCP8.5). We found that in recent decades the share of extremely warm days has at least doubled over the period December-January-February (DJF) in northern SA; less significant increases have been observed in southern SA. We also found that by midcentury, under the RCP4.5 scenario, extremely warm DJF days (as well as the number of HWs per season) are expected to increase by 5-10 times at locations close to the Equator and in the Atacama Desert. Increases are expected to be less pronounced in southern SA. Projections under the RCP8.5 scenario are more striking, particularly in tropical areas where half or more of the days could be extremely warm by midcentury.

Abstract
Soiling by dry deposition affects the power output of photovoltaic (PV) modules, especially under dry and arid conditions that favor natural atmospheric aerosols (wind-blown dust). In this paper, we report on measurements of the soiling effect on the energy yield of grid-connected crystalline silicon PV modules deployed in five cities across a north-south transect of approximately 1300 km in the Atacama Desert ranging from latitude 18°S to latitude 30°S. Energy losses were assessed by comparing side-by-side outputs of four co-planar PV modules. Two of the PV modules of the array were kept clean as a control, while we allowed the other two to naturally accumulate soiling for 12 months (from January 2017 to January 2018). We found that the combination of high deposition rates and infrequent rainfalls led to annual energy losses that peaked at 39% in the northern coastal part of the desert. In contrast, annual energy losses of 3% or less were measured at relatively high-altitude sites and also at locations in the southern part of the desert. For comparison, soiling-induced annual energy losses of about 7% were measured in Santiago, Chile (33°S), a major city with higher rainfall frequency but where urban pollution plays a significant role.

Abstract
The world's highest levels of surface ultraviolet (UV) irradiance have been measured in the Atacama Desert. This area is characterized by its high altitude, prevalent cloudless conditions, and a relatively low total ozone column. In this paper, we provide estimates of the surface UV (monthly UV index at noon and annual doses of UV-B and UV-A) for all sky conditions in the Atacama Desert. We found that the UV index at noon during the austral summer is expected to be greater than 11 in the whole desert. The annual UV-B (UV-A) doses were found to range from about 3.5 kWh/m2 (130 kWh/m2) in coastal areas to 5 kWh/m2 (160 kWh/m2) on the Andean plateau. Our results confirm significant interhemispherical differences. Typical annual UV-B doses in the Atacama Desert are about 40% greater than typical annual UV-B doses in northern Africa. Mostly due to seasonal changes in the ozone, the differences between the Atacama Desert and northern Africa are expected to be about 60% in the case of peak UV-B levels (i.e. the UV-B irradiances at noon close to the summer solstice in each hemisphere). Interhemispherical differences in the UV-A are significantly lower since the effect of the ozone in this part of the spectrum is minor.

Abstract
There is preliminary evidence that the immune system's cytokines may have impact on ADHD in children. Nevertheless, studies exploring the possible role of pro-inflammatory cytokines in adults with ADHD are lacking. This study aimed to assess differences in serum IL-6 and TNF-α between patients and controls and their possible relationship to resting cortisol. 108 adults with ADHD (DSM-IV), 44 inattentive and 64 combined, age ranging between 18 and 55 years, and 27 healthy controls were included. Major psychiatric disorders and organic comorbidities were excluded. Serum samples for IL-6 and TNF-α and salivary samples to assess cortisol awakening response were collected on the same day. Analysis of variance was applied to study differences in IL-6 and TNF-α between groups. Pearson correlations were used to study associations between IL-6, TNF-α, and CAR. There were no significant differences in serum IL-6 or TNF-α levels between patients and controls or between combined and inattentive patients. Negative associations between IL-6 (r=-0.386, p=0.020), TNF-α (r=-0.372, p=0.023) and cortisol awakening response were found in the inattentive subtype, whereas no association was seen in the combined subtype. A negative correlation between IL-6 and cortisol was also present in the control group (r=-0.44, 0.030). The peripheral pro-inflammatory markers, IL-6 and TNF-α, do not appear to be primarily involved in ADHD in adults, although the role of other inflammatory markers cannot be ruled out. The differences regarding the association between IL-6 and TNF-α and morning cortisol response suggest possible underlying neurobiological differences between the inattentive or combined patients that merit further studies.

Abstract
Ozone (O3) soundings have been performed on Easter Island or Rapa Nui (27°S, 23 109°W, 51 m a.s.l.) since 1994 as part of the Global Atmospheric Watch (GAW) Programme of the World Meteorological Organization (WMO). In this work, we analyze 260 soundings compiled over the period 1994-2014, and make the data available for the international community. We characterize O3 profiles over this remote area of the Pacific by means of statistical analyses that consider, on the one hand, a traditional climatology that describes the data in terms of seasonal cycles based on monthly averages and, on the other hand, a process oriented analysis based on self-organizing maps. Our analyses show the influence of both tropical and subtropical/mid-latitude air masses at Rapa Nui. The former occurs in summer and fall when convective conditions prevail, and the latter in late winter and spring when subsiding conditions are recurrent. The occurrence of stratospheric intrusions in late winter and spring in connection with deep troughs and the presence of the subtropical jet stream is also apparent in the data set. The tropospheric ozone column is in good agreement with the corresponding data derived from satellites but with a systematic overestimate of summer and fall values. We show evidence of an upward trend in ozone near the surface, which suggests the impact of local pollution. We look forward to an enhancement of the Rapa Nui observing site, given its location that offers a privileged position to observe climate change over the sparsely sampled and vast South Pacific Ocean.

Abstract
Interferon-γ (IFN-γ) is known for its important antiviral activity and other immunomodulatory actions. In in vitro studies, this cytokine has also been involved in the control of metallothionein (MT) synthesis. MT is a low molecular weight protein comprised of several isoforms called MT-I to MT-IV; of these, MT-1+11 are widely expressed, whereas MT-III and MT-IV are rather tissue specific. In the present report, we have studied in vivo the role of IFN-γ for a normal liver and brain MT-I+II response to immobilization stress and to an inflammatory process caused by bacterial lipopolysaccharide (LPS, endotoxin), using mice carrying a null mutation in the IFN-γ receptor gene (IFN-γR-/-). Liver MT-I mRNA and MT-(I+II) protein levels during stress of IFN-γR-/- mice were similar to those of the two parental mouse strains used to generate them, namely C57BU6 and 129/Sv mice, and that of the F1 C57BU6 x 129/Sv offspring mice. In contrast, liver MT response to LPS was significantly higher in the IFN-γR-/- mice than in the other strains. MT-I+II response to LPS was also higher in IFN-γR-/- mice in medulla plus pons and tended to in hypothalamus, hippocampus, and cerebellum, but not in the remaining brain. These results suggest that a role of IFN-γ on liver and brain MT-I+II response to stress is unlikely, but that this cytokine exerts an inhibitory effect on the signaling pathways activated by LPS involved in MT-I+II regulation. In situ hybridization analysis for MT-I and MT-III mRNAs of control mice revealed significant effects of the functional IFN-γ deficiency on MT-I but not MT-III mRNA levels in the dentate gyrus and the habenula, while no effects were observed in the remaining brain areas studied.

Abstract
There is little evidence about barriers to pain management or their relationships with pain outcomes of hospice patients with cancer. The purpose of the study was to determine the barriers reported by hospice patients with cancer and their caregivers and the relationships with demographic characteristics and the patients’ pain. In this cross-sectional study, we used selected baseline data from an ongoing randomized clinical trial of patient and lay caregiver dyads receiving home-level hospice care. Participants used an Internet-enabled tablet to complete the valid, reliable measures of pain intensity, pain management barriers (Barriers Questionnaire 13 items [BQ-13]), and demographic characteristics. The responses indicate that the 2 areas of highest concern (mean scores >3) to both patients and caregivers were “pain means disease progression” and “constipation.” Additionally, 3 other areas of highest concern (mean scores >3) to caregivers were “addiction” pain medicine causing “one to do embarrassing things” and “confusion.” The mean BQ-13 scores ranged from 0.2 to 4.9 and averaged 2.6 ± 0.9 for the patients and ranged from 0.5 to 4.7 and averaged 2.7 ± 0.9 for the caregivers. Mean barrier scores remain high and were not different between patients and their caregivers or significantly related to the patients’ pain intensity. However, there were differences in race, ethnic, and hospice setting in the barrier scores. Patients with Hispanic heritage reported higher barrier scores than non-Hispanic patients. Together, these findings not only support prior research findings but also contribute new insights about pain intensity and pain barriers that are relevant to hospices serving minorities with cancer.

Abstract
The Atacama Desert has been pointed out as one of the places on earth where the highest surface irradiance may occur. This area is characterized by its high altitude, prevalent cloudless conditions and relatively low columns of ozone and water vapor. Aimed at the characterization of the solar spectrum in the Atacama Desert, we carried out in February-March 2015 ground-based measurements of the spectral irradiance (from the ultraviolet to the near infrared) at seven locations that ranged from the city of Antofagasta (on the southern pacific coastline) to the Chajnantor Plateau (5,100 m altitude). Our spectral measurements allowed us to retrieve the total ozone column, the precipitable water, and the aerosol properties at each location. We found that changes in these parameters, as well as the shorter optical path length at high-altitude locations, lead to significant increases in the surface irradiance with the altitude. Our measurements show that, in the range 0–5100 m altitude, surface irradiance increases with the altitude by about 27% in the infrared range, 6% in the visible range, and 20% in the ultraviolet range. Spectral measurements carried out at the Izaña Observatory (Tenerife, Spain), in Hannover (Germany) and in Santiago (Chile), were used for further comparisons.

Abstract
Abstract
BACKGROUD: The immunogenicity of some human tumors towards T lymphocytes is well established. Recently, encouraging results have been obtained with immunotherapies inhibiting immune checkpoints in cancers such as melanoma, NSCLC and bladder cancer. Fewer studies explored these treatments in breast cancer (BC) as these tumors are often considered to be poorly immunogenic.
METHODS: We analysed the T cell receptor β-chains variable genes (TCRBV) repertoires of tumor-infiltrating T cells in 17 early BC. We looked for clonally amplified T cells as their presence is an expected consequence of tumor immunogenicity. RNA was extracted and reverse-transcribed from formalin-fixed, paraffin-embedded tumor tissues. A short random sequence was added to the cDNA and used as a unique molecular identifier (UMI) for each cDNA molecule. cDNA encoding TCRBV genes was then amplified and sequenced using high throughput sequencing. Usage of UMIs during this procedure strongly improved the accuracy of the analysis by avoiding amplification biases inherent to the construction of the TCRBV library and by allowing an absolute quantification of TCRBV mRNA molecules normalized with the RPP30 housekeeping gene. TCRBV sequences were aligned using IMGT/HighV-QUEST. The Simpson's index was used to evaluate TCRBV repertoires diversity (ranging from 0 = infinite diversity to 1 = no diversity). For 3 patients, the same procedure was applied on blood T cells collected a few days before tumor resection and the analysis was also carried out on 3 normal tissues obtained from breast reduction surgery.
RESULTS: T cell infiltration varied strongly from one tumor to another ranging from 5 to 2498 TCRBV/103 RPP30 mRNA molecules. TCRBV repertoires analysis indicated that infiltrated T cells corresponded to oligoclonal populations. We observed 3 clonotypes in the smaller repertoire and 74 in the largest one and the Simpson's index ranged from 0.01 to 0.65. Most tumors (16/17) contained at least one clonotype that made up ≥10% of the infiltrating T cells, with the highest observed proportions reaching 80%. Normal breast samples were infiltrated by a more diverse repertoire: 130 to 368 clonotypes were identified in those tissues and Simpson's index ranged from 0.002 to 0.008. Highest observed frequency among those clonotypes was 2%. For 3 BC patients, the frequencies of the most prevalent clonotypes in the tumor were compared to those of the same clonotypes in blood prior to surgery. These T cell clones were 250 to >34000 times more frequent in the tumor than in the blood.
CONCLUSIONS: Some early BC are infiltrated by oligoclonal T cell populations that are highly enriched relative to the blood. Quantitative T cell repertoire analysis allows to distinguish 3 types of BC: (1) tumors without T cell infiltration, (2) tumors with a high T cell infiltration and a small T cell repertoire, and (3) tumors with a high T cell infiltration and a large repertoire. Our observations suggest that anti-tumor T cell responses are ongoing in some early BC and this warrants boosting such responses with immune checkpoint inhibitors in selected patients. T cell repertoire evaluation could be used as a predictive biomarker to identify patients who will benefit from this treatment.

Abstract
Abstract
Background: Immunotherapy through stimulatory antibodies targeting the CTLA-4 or PD-1 pathways has a clear clinical efficacy in a fraction of patients with various cancers. It is likely that the main immune effectors of these therapies are CD8+ cytolytic T lymphocytes (CTL) recognizing tumor-specific antigens. The antigenicity of human tumors has been demonstrated with studies conducted mostly on melanomas. However the genetic mechanisms leading to antigenicity, notably point mutations in the tumor cells, apply to all cancer types. Thus primary breast carcinoma cells do certainly bear tumor-specific antigens, even though the extent of this antigenicity is unknown. Most melanomas, which are highly antigenic tumors, are also immunogenic, i.e. they stimulate spontaneous anti-tumor CTL responses. This immunogenicity, of which the presence of tumor-infiltrating T cells (TILs) is probably a surrogate marker, might be a predictive marker for clinical benefit to immunostimulatory antibodies. Whether primary breast carcinomas are immunogenic is not known, mainly due the absence of autologous tumor cell lines to analyze patients' T cells. However even in the absence of T-cell aimed immunotherapy the amounts of TILs have been positively correlated with patients' survival. Here we wished to obtain evidence for the presence of tumor-specific CD8+ T cells in TILs from primary breast carcinomas.
Methods: From each tumor we isolated TILs and derived a random set of ±100 CD8+ clones maintained in culture by stimulation with anti-CD3 antibodies, thus irrespective of their antigenic specificity. We screened these clones for recognition of tumor-specific antigens present on the autologous tumor. In the absence of autologous tumor lines we restricted our analysis to mutated antigens selected on the basis of tumor exome sequencing and gene expression profiling. Indels and non-synonymous base substitutions were selected to synthesize candidate mutated peptides.
Results: Thus far we have analyzed two hormone receptor-positive HER2-negative primary carcinomas. For one patient we screened 144 T cell clones for recognition of 40 candidate mutated peptides, without any positive result. For the other patient, 6 out of 98 T cell clones recognized 4 out of 119 candidate mutated peptides. Two peptides were recognized by two different T cell clones, i.e. with different T cell receptor sequences. These 4 'antigenic' mutations appear to be passenger, i.e. the four genes have a low published mutation frequency.
Conclusions: We conclude that some human primary breast carcinomas are immunogenic, as one tumor contained at least 6% of tumor-specific T cells among the CD8+ TILs. It suggests that the corresponding patient could benefit from the currently used immunostimulatory antibodies. More work is required to understand the reasons for the negative results in the first patient. We are pursuing the work on 2 HER2-positive and 2 triple-negative tumors, in which TILs are better correlated with prognosis. Our results warrant more investigations on the activation or inhibition of tumor-specific T cells at early stages of human breast cancer development.

Abstract
AIM Interleukin-6 (IL-6) is a major cytokine controlling body weight and metabolism, but because many types of cells can synthesize and respond to IL-6 considerable uncertainty still exists about the mechanisms underlying IL-6 effects. Therefore, the aim of this study was to analyse the effects of tissue-specific deletion of IL-6 using a fatty acid binding protein (aP2) promoter-Cre inducible system (aP2-Cre-ERT2). METHODS Tissue-specific IL-6 KO mice (aP2-IL-6 KO mice) were produced upon tamoxifen administration and were fed a high-fat diet (HFD, 58.4% kcal from fat) or a control diet (18%) for 14 weeks. RESULTS aP2-IL-6 KO female mice on a HFD gained less weight and adiposity than littermate wild-type mice, but these effects were not observed in males. Hypothalamic factors such as NPY and AgRP showed a pattern of expression consistent with this sex-specific phenotype. PGC-1α expression was increased in several tissues in aP2-IL-6 KO female mice, which is compatible with increased energy expenditure. Serum leptin, insulin, glucose, cholesterol and triglycerides levels were increased by HFD, and in females IL-6 deficiency reversed this effect in the case of insulin and cholesterol. HFD induced impaired responses to insulin and glucose tolerance tests, but no significant differences between genotypes were observed. CONCLUSION The present results demonstrate that deletion of IL-6 driven by aP2-Cre regulates body weight, body fat and metabolism in a sex-specific fashion.

Abstract
Abstract
Background: Triple Negative Breast Cancers (TNBC) represent 12% to 20% of total Breast Cancers (BC) and have a worse outcome compared with other breast cancer subtypes. TNBC often show a deficiency in DNA double strand break repair mechanisms. This deficiency is generally related to inactivation of a repair enzymatic complex involving BRCA1 caused either by genetic mutations, epigenetic modifications, or by post-transcriptional regulations. The identification of BC presenting a BRCA1 deficiency could be useful to select patients that could benefit from PARP inhibitors, alkylant agents or platinum-based chemotherapy.
In this study, we have identified by Comparative Genomic Hybridization array (CGH-array) a recurrent gain in 17q25.3 characteristic of BRCA1 mutated or methylated TNBC.
Methods: 130 formalin-fixed paraffin embedded (FFPE) tumours including TNBC (unknown-BRCA1-status, BRCA1 mutated and non-mutated), Luminal A, Luminal B, Her2-neu amplified (Her2+) BC and BRCA1-mutated non-TNBC (mutated-Luminal A, Luminal B, Her2+) were obtained from our local tumour collection. DNA was extracted and genomic copy-number alterations were analysed by CGH-array (Agilent, SuperPrint G3 Human CGH 8×60K Oligo Microarrays). FISH analyses were performed on section from FFPE samples to validate some chromosomal aberrations belonging to the 17q25.3 amplified region evidenced by CGH-array. The study of BRCA1 promoter methylation status in all tumours was carried out by MDxHealth (Liege, Belgium).
Results: In this study, we have identified by CGH-array a genomic region (17q25.3) amplified in 90% of the BRCA1 mutated tumours (29/32). This chromosomal gain was studied in other subtypes of BC by CGH-array and it was only evidenced in 30% (6/20) of BRCA1 non-mutated TNBC, 26.67% (4/15) of unknown-BRCA1-status TNBC, 13.64% (3/22) of Luminal B, 19.05% (4/21) of Her2+ and 0% (0/20) of Luminal A breast cancers. FISH assays confirmed these chromosomal amplifications and evidenced like CGH array analyses a significant difference between BRCA1 mutated and non-mutated BC for the 17q25.3 gain.
BRCA1 methylation was found only in TNBC (11/58) and was not found in the BRCA1-mutated BC cohort, nor in the Luninal A, Luminal B and Her2+ samples. In BRCA1 non-mutated TNBC, the methylation was found in 8 cases including 4 with 17q25.3 amplification. In the unknown-BRCA1-status TNBC, 3 methylated samples were found with 1 case with co-amplification of the 17q25.3 region.
Recurrence of 17q25.3 amplification in BRCA1 mutated tumours as well as its detection in BC having a methylation in BRCA1 promoter suggests that the 17q25.3 gain could be a marker of the BRCA1 deficiency. Identification of relevant genes whose expression is up-regulated within the recurrently gained region is underway.
Conclusions: The CGH signature observed in 17q25.3 chromosomal region and FISH assay developed in this study could allow the identification of “BRCAness” breast tumours, improving the diagnostic performance and orienting the selection of the appropriate therapy. The up-regulated genes themselves might also represent potential therapeutic targets.

Abstract
Between 2008 and 2011, symptoms of cobweb were observed in commercial white button mushroom (Agaricus bisporus) crops in Castilla-La Mancha (Spain). Typical symptoms started as white, cobweb-like mycelial growth over the surface of the casing soils and fruiting bodies. Later, the mycelium changed to a grayish white, dense powder and the affected fruiting bodies turned pale yellow or reddish brown before rotting. Two types of cap spotting were observed, dark brown spots with a poorly defined edge and light brown spots. The first symptoms were commonly seen in the second or third break (flush) of mushrooms. Infected tissues of A. bisporus were plated onto potato dextrose agar (PDA) and a parasitic fungus was isolated. Fungal colonies consisted of abundant, cottony, aerial mycelium spreading rapidly over the PDA, and red pigment spreading into the agar. The cultures lacked a camphor odor. Conidiogenous cells were 24 to 45 μm long, 3 to 6 μm wide basally, and tapered slightly to the tip. Conidia were cylindrical to narrowly ellipsoidal, 15 to 28 × 8 to 11 μm, and zero- to three-septate. Total DNA was extracted and the internal transcribed spacer (ITS) region of rDNA amplified for one mycelial isolate using ITS1F/ITS4 primers (2,4). The amplicon was sequenced (GenBank Accession No. JQ004732). BLAST analysis showed highest similarity (99 and 100%) of the ITS sequence to four ITS sequences of Cladobotryum mycophilum (teleomorph Hypomyces odoratus) (GenBank Accession Nos. AB527074, JF505112, Y17095, and Y17096) (1,3) among other sequences of the same species. Two pathogenicity trials (A and B) were performed in mushroom-growing rooms, with 24 blocks in each assay containing pasteurized, spawned, and incubated A. bisporus substrate (10 kg, 0.15 m2). The blocks were cased with a 35-mm layer of a peat-based casing soil (5.5 liter/block). Nine days after casing, a conidial suspension (7.5 × 103 conidia/ml) of one isolate of C. mycophilum was sprayed (20 ml/block) onto the surface of the casing layer of 12 blocks at 106 conidia/m2. Twelve blocks were sprayed with sterile distilled water as a control treatment. Blocks were maintained at 17.5°C and 90% relative humidity. The first cobweb symptoms developed 25 days after inoculation, between the second and third breaks in trial A; and after 11 days, between the first and second breaks in trial B. C. mycophilum was consistently reisolated from eight inoculated blocks (67%) in trial A, and 11 inoculated blocks (92%) in trial B. The total area of the crop affected by cobweb was 30% in inoculated blocks in trial A and 45% in trial B. The noninoculated blocks remained healthy. Compared with the noninoculated control blocks, a 10.7% decrease in yield of mushrooms was observed in trial A and 9.1% in trial B. Previously, C. dendroides was the only known causal agent of cobweb in Spain. To our knowledge, this is the first report of C. mycophilum causing cobweb in white button mushroom in Spain, although the disease and causal agent were previously reported on cultivated king oyster mushroom (Pleurotus eryngii) in Spain (3).

Abstract
The dietary intake of total arsenic (tAs), inorganic arsenic (iAs) and total mercury (tHg) in lunch and breakfast servings provided by the Chilean School Meal Program (SMP) was estimated, using the duplicate-portion variant of the total diet study. Lunch and breakfast samples were collected from 65 schools throughout the country in 2006. The population sample was a group of girls and boys between 6 and 18 years old. The tAs concentration was measured via hydride-generation atomic absorption spectrometry. The total mercury concentration was measured via cold-vapor atomic absorption spectroscopy. The estimated iAs intake was 12.5% (5.4 μg/day) of the Provisional tolerable daily intake (PTDI) as proposed by the FAO/WHO, and the tHg intake was 13.2% (1.9 μg/day) of the PTDI as proposed by the FAO/WHO. It was therefore concluded that tAs, iAs and tHg intake from food provided by the SMP do not pose risks to student health.

Abstract
AIM Upper oesophageal pH monitoring may play a significant role in the study of extra-oesophageal GERD, but limited normal data are available to date. Our aim was to develop a large series of normal values of proximal oesophageal acidification. METHODS 155 healthy volunteers (74 male) participated in a multi-centre national study including oesophageal manometry and 24 hours oesophageal pH monitoring using two electrodes individually located 5 cm above the LOS and 3 cm below the UOS. RESULTS 130 participants with normal manometry completed all the study. Twelve of them were excluded for inadequate pH tests. Twenty-seven subjects had abnormal conventional pH. The remaining 91 subjects (37 M; 18-72 yrs age range) formed the reference group for normality. At the level of the upper oesophagus, the 95th percentile of the total number of reflux events was 30, after eliminating the meal periods 22, and after eliminating also the pseudo-reflux events 18. Duration of the longest episodes was 5, 4 and 4 min, respectively (3.5 min in upright and 0.5 min in supine). The upper limit for the percentage of acid exposure time was 1.35, 1.05 and 0.95%, respectively. No reflux events were recorded in the upper oesophagus in 8 cases. CONCLUSION This is the largest series of normal values of proximal oesophageal reflux that confirm the existence of acid reflux at that level in healthy subjects, in small quantity and unrelated to age or gender. Our data support the convenience of excluding pseudo-reflux events and meal periods from analysis.

Abstract
INTRODUCTION FOLFOX 4 chemotherapy (5-fluorouracil, leucovorin and oxaliplatin) is the standard adjuvant treatment for stage III colon cancer. The principal secondary effects described are haematological, gastro-intestinal or neurological. A single case of obliterative bronchiolitis with organising pneumonia has been described recently. CASE REPORT We report the case of a female patient aged 74 years who, after 12 courses of FOLFOX 4 chemotherapy, developed acute onset of severe shortness of breath and a dry cough but remained afebrile. A thoracic CT-scan showed symmetrical bilateral interstitial infiltration that was reticular in appearance, and predominantly basal and peripheral in distribution. Broncho-alveolar lavage revealed an alveolitis with 9% eosinophils and 4% neutrophils. Transbronchial biopsies showed the appearances of obliterative bronchiolitis with organising pneumonia. Systemic corticosteroid treatment led to a remarkable clinical and functional improvement. CONCLUSION To our knowledge, this is the second case of obliterative bronchiolitis with organising pneumonia that has been described following adjuvant treatment based on FOLFOX 4.

Abstract
Previous studies have described altered expression of metallothioneins (MTs) in neurodegenerative diseases like multiple sclerosis (MS), Down syndrome, and Alzheimer's disease (AD). In order to gain insight into the possible role of MTs in neurodegenerative processes and especially in human diseases, the use of animal models is a valuable tool. Several transgenic mouse models of AD amyloid deposits are currently available. These models express human beta-amyloid precursor protein (AbetaPP) carrying different mutations that subsequently result in a varied pattern of beta-amyloid (Abeta) deposition within the brain. We have evaluated the expression of MT-I and MT-III mRNA by in situ hybridization in three different transgenic mice models of AD: Tg2576 (carrying AbetaPP harboring the Swedish K670N/M671L mutations), TgCRND8 (Swedish and the Indiana V717F mutations), and Tg-SwDI (Swedish and Dutch/Iowa E693Q/D694N mutations). MT-I mRNA levels were induced in all transgenic lines studied, although the pattern of induction differed between the models. In the Tg2576 mice MT-I was weakly upregulated in cells surrounding Congo Red-positive plaques in the cortex and hippocampus. A more potent induction of MT-I was observed in the cortex and hippocampus of the TgCRND8 mice, likely reflecting their higher amyloid plaques content. MT-I upregulation was also more significant in Tg-SwDI mice, especially in the subiculum and hippocampus CA1 area. Immunofluorescence stainings demonstrate that astrocytes and microglia/macrophages surrounding the plaques express MT-I&II. In general, MT-I regulation follows a similar but less potent response than glial fibrillary acidic protein (GFAP) expression. In contrast to MT-I, MT-III mRNA expression was not significantly altered in any of the models examined suggesting that the various MT isoforms may have different roles in these experimental systems, and perhaps also in human AD.

Abstract
The neutral oxygen vacancy (OV) energy formation for bulk, subsurface sites at different depths from the surface and various surface sites has been estimated for single crystals, unsupported ultrathin films of MgO, CaO, and BaO, and MgO ultrathin films supported on Ag(001). From the calculated energy barriers for diffusion through the surface and from the surface to the bulk it is found that diffusion is a hindered event, especially for MgO. Nevertheless, diffusion from the terrace to step edges is largely favored while diffusion through terrace sites is less likely and surface to bulk has a very low probability. It is argued that this explains recent scanning tunneling microscopy images for MgO thin films supported on Ag(001) showing OV populating preferentially the step edge sites.

Abstract
Oxygen vacancies in metal oxides are known to determine their chemistry and physics. The properties of neutral oxygen vacancies in metal oxides of increasing complexity (MgO, CaO, alpha-Al2O3, and ZnO) have been studied using density functional theory. Vacancy formation energies, vacancy-vacancy interaction, and the barriers for vacancy migration are determined and rationalized in terms of the ionicity, the Madelung potential, and lattice relaxation. It is found that the Madelung potential controls the oxygen vacancy properties of highly ionic oxides whereas a more complex picture arises for covalent ZnO.
