Abstract
Planets with radii between that of the Earth and Neptune (hereafter referred to as 'sub-Neptunes') are found in close-in orbits around more than half of all Sun-like stars1,2. However, their composition, formation and evolution remain poorly understood3. The study of multiplanetary systems offers an opportunity to investigate the outcomes of planet formation and evolution while controlling for initial conditions and environment. Those in resonance (with their orbital periods related by a ratio of small integers) are particularly valuable because they imply a system architecture practically unchanged since its birth. Here we present the observations of six transiting planets around the bright nearby star HD 110067. We find that the planets follow a chain of resonant orbits. A dynamical study of the innermost planet triplet allowed the prediction and later confirmation of the orbits of the rest of the planets in the system. The six planets are found to be sub-Neptunes with radii ranging from 1.94R⊕ to 2.85R⊕. Three of the planets have measured masses, yielding low bulk densities that suggest the presence of large hydrogen-dominated atmospheres.

Abstract
Recent advances in molecular profiling, have reclassified medulloblastoma, an undifferentiated tumor of the posterior fossa, in at least four diseases, each one with differences in prognosis, epidemiology and sensibility to different treatments. The recommended management of a lesion with radiological characteristics suggestive of MB includes maximum safe resection followed by a post-surgical MR < 48 h, LCR cytology and MR of the neuroaxis. Prognostic factors, such as presence of a residual tumor volume > 1.5 cm2, presence of micro- or macroscopic dissemination, and age > 3 years as well as pathological (presence of anaplastic or large cell features) and molecular findings (group, 4, 3 or p53 SHH mutated subgroup) determine the risk of relapse and should guide adjuvant management. Although there is evidence that both high-risk patients and to a lesser degree, standard-risk patients benefit from adjuvant craneoespinal radiation followed by consolidation chemotherapy, tolerability is a concern in adult patients, leading invariably to dose reductions. Treatment after relapse is to be considered palliative and inclusion on clinical trials, focusing on the molecular alterations that define each subgroup, should be encouraged. Selected patients can benefit from surgical rescue or targeted radiation or high-dose chemotherapy followed by autologous self-transplant. Even in patients that are cured by chemorradiation presence of significant sequelae is common and patients must undergo lifelong follow-up.

Abstract
Spectroscopy of transiting exoplanets can be used to investigate their atmospheric properties and habitability. Combining radial velocity (RV) and transit data provides additional information on exoplanet physical properties. We detect a transiting rocky planet with an orbital period of 1.467 days around the nearby red dwarf star Gliese 486. The planet Gliese 486 b is 2.81 Earth masses and 1.31 Earth radii, with uncertainties of 5%, as determined from RV data and photometric light curves. The host star is at a distance of ~8.1 parsecs, has a J-band magnitude of ~7.2, and is observable from both hemispheres of Earth. On the basis of these properties and the planet's short orbital period and high equilibrium temperature, we show that this terrestrial planet is suitable for emission and transit spectroscopy.

Abstract
Furans represent one of the most important classes of intermediates in the conversion of non-edible lignocellulosic biomass into bio-based chemicals and fuels. At present, bio-furan derivatives are generally obtained from cellulose and hemicellulose fractions of biomass via the acid-catalyzed dehydration of their relative C6-C5 sugars and then converted into a wide range of products. Furfural (FUR) and 5-hydroxymethylfurfural (HMF) are surely the most used furan-based feedstocks since their chemical structure allows the preparation of various high-value-added chemicals. Among several well-established catalytic approaches, hydrogenation and oxygenation processes have been efficiently adopted for upgrading furans; however, harsh reaction conditions are generally required. In this review, we aim to discuss the conversion of biomass derived FUR and HMF through unconventional (transfer hydrogenation, photocatalytic and electrocatalytic) catalytic processes promoted by heterogeneous catalytic systems. The reaction conditions adopted, the chemical nature and the physico-chemical properties of the most employed heterogeneous systems in enhancing the catalytic activity and in driving the selectivity to desired products are presented and compared. At the same time, the latest results in the production of FUR and HMF through novel environmental friendly processes starting from lignocellulose as well as from wastes and by-products obtained in the processing of biomass are also overviewed.

Abstract
INTRODUCTION A comparative clinical study has been conducted on patients involved using lateral intersomatic arthrodesis for the treatment of adjacent segment disease using titanium and PEEK intersomatic devices. MATERIAL AND METHODS Clinical (EVA and oswestry disability index ODI) and radiological (alignment and fusion), complications (major and minor) and quality of life (EQ5D) of 32 patients intervened from September 2015 to September 2018 have been analyzed and compared, with an average follow-up of 25 months (46-18). The average age in surgery was 66 years (39-89) and 68% of patients were women. RESULTS The most common segment involved was L3-L4 (62%) right retroperitoneal approach 86%. Lumbar EVA improved from 6.2 ± 2.12 to 4.1 ± 1.71 (p = 0.028). The LEG EVA descended from 5.3 ± 2.26 to 1.9 ± 1.58 (p = 0.02). The ODI scales improved from 50.2 ± 18.9 to 33.3 ± 10.2 (p = 0.025) and the EQ5D went from 0.52 to 0.73 (p = 0.039) with no statistically significant differences between the groups (ODI p = 0.18, EQ5D p = 0.293). Radiologically increased intervertebral height, lumbar and segmental lordosis, decreased Cobb's angle and the overall melting rate was 84.3% (88% Ti/82% PEEK), with no differences between the groups. CONCLUSION Lateral lumbar interbody fusion is an effective method for treating adjacent segment disease with clinical-radiological results and literature-like complications. No differences have been found between Ti and PEEK implants.

Abstract
The closet exoplanets to the Sun provide opportunities for detailed characterization of planets outside the Solar System. We report the discovery, using radial velocity measurements, of a compact multiplanet system of super-Earth exoplanets orbiting the nearby red dwarf star GJ 887. The two planets have orbital periods of 9.3 and 21.8 days. Assuming an Earth-like albedo, the equilibrium temperature of the 21.8-day planet is ~350 kelvin. The planets are interior to, but close to the inner edge of, the liquid-water habitable zone. We also detect an unconfirmed signal with a period of ~50 days, which could correspond to a third super-Earth in a more temperate orbit. Our observations show that GJ 887 has photometric variability below 500 parts per million, which is unusually quiet for a red dwarf.

Abstract
Surveys have shown that super-Earth and Neptune-mass exoplanets are more frequent than gas giants around low-mass stars, as predicted by the core accretion theory of planet formation. We report the discovery of a giant planet around the very-low-mass star GJ 3512, as determined by optical and near-infrared radial-velocity observations. The planet has a minimum mass of 0.46 Jupiter masses, very high for such a small host star, and an eccentric 204-day orbit. Dynamical models show that the high eccentricity is most likely due to planet-planet interactions. We use simulations to demonstrate that the GJ 3512 planetary system challenges generally accepted formation theories, and that it puts constraints on the planet accretion and migration rates. Disk instabilities may be more efficient in forming planets than previously thought.

Abstract
Abstract
BACKGROUND
Standard treatment of glioblastoma (GBM) is focal radiation with concomitant and adjuvant temozolomide (TMZ) for 6 cycles. The GEINO-14-01 trial (NCT02209948) investigated the role of extending adjuvant TMZ to 12 cycles in a randomized multicenter study.
MATERIAL AND METHODS
Between Aug/2014 and Nov/2018, 166 patients (p) were screened and 159 randomized to extend (80p) or not (79p) TMZ treatment to 12 cycles after proving stable disease in the MRI performed before inclusion. The trial was stratified by MGMT status and presence or absence of residual disease (defined as a residual enhancement larger than 1cm on the MRI). The primary endpoint was differences in 6monthsPFS, secondary endpoints were differences in PFS, OS, toxicity, between arms and per stratification factors.
RESULTS
Median age was 60.4 (range 29–83), 97p (61%) were methylated and 83 p (52.2%) were reported with residual disease. Median (m) PFS was 7.9 months (95%CI: 6.1–9.8) and mOS: 20.9 (95%CI: 17.6–24.1). A methylated status was a factor of better PFS (HR=0.29, 95% CI 0.46–0.95; p=0.029) and better OS (HR= 0.43: 95% CI 0.28–0.66; p=0.000) as well as the absence of residual disease (PFS: HR = 0.84: 95% CI =0.71–1.01; p=0.068; OS: HR=0.77, 95%CI 0.63–0.96; p=0.019). We didn’t find any difference in PFS (HR=1.02, 95%CI 0.85–1.21; p=0.82), or OS (HR=0.90; 0.73–1.11; p=0.34) on extending treatment with temozolomide longer than 6 cycles.
CONCLUSION
There is no benefit of continuing TMZ treatment for more than 6 cycles in the adjuvant treatment of glioblastoma. Final data will be presented at the congress. Supported by a Grant of the ISCIII: PI13/01751

Abstract
PURPOSE We retrospectively examined the potential effect on overall survival (OS) of delaying radiotherapy to administer neoadjuvant therapy in unresected glioblastoma patients. PATIENTS AND METHODS We compared OS in 119 patients receiving neoadjuvant therapy followed by standard treatment (NA group) and 96 patients receiving standard treatment without neoadjuvant therapy (NoNA group). The MaxStat package of R identified the optimal cut-off point for waiting time to radiotherapy. RESULTS OS was similar in the NA and NoNA groups. Median waiting time to radiotherapy after surgery was 13 weeks for the NA group and 4.2 weeks for the NoNA group. The longest OS was attained by patients who started radiotherapy after 12 weeks and the shortest by patients who started radiotherapy within 4 weeks (12.3 vs 6.6 months) (P = 0.05). OS was 6.6 months for patients who started radiotherapy before the optimal cutoff of 6.43 weeks and 19.1 months for those who started after this time (P = 0.005). Patients who completed radiotherapy had longer OS than those who did not, in all 215 patients and in the NA and NoNA groups (P = 0.000). In several multivariate analyses, completing radiotherapy was a universally favorable prognostic factor, while neoadjuvant therapy was never identified as a negative prognostic factor. CONCLUSION In our series of unresected patients receiving neoadjuvant treatment, in spite of the delay in starting radiotherapy, OS was not inferior to that of a similar group of patients with no delay in starting radiotherapy.

Abstract
Abstract
Background: Triple negative breast cancer (TNBC) patients with residual disease are characterized for a bad outcome. In these patients nodal involvement after neoadjuvant chemotherapy (NAC) is one of the most important prognostic determinants. In this study we compare two prognostic variables based on nodal status, the lymph node ratio (LNR=#positive nodes/#resected nodes) and residual lymph node status (ypN) in TNBC who received NAC.
Methods: We evaluated a retrospective cohort of TNBC patients with residual disease in the lymph nodes (at least 4 resected nodes) and treated with NAC between 2000-2014 at the Instituto Nacional de Enfermedades Neoplasicas (Lima-Peru). Patients were grouped in three LNR groups (≤0.20, 0.20-0.69 and ≥0.70). Survival differences were calculated by the log rank test. Prognostic factors for progression free survival (PFS) and overall survival (OS) were assessed by the Cox regression analysis.
Results: Overall, 189 were evaluated. Mean age was 48y (range: 26-73) where 53.5% were premenopausal and 16.5% had breast/ovary cancer familial background. A total of 175 pts (92.6%) had clinical T3-T4 tumors and 85.2% had nodal involvement at diagnosis. Indeed, the majority of patients had III CS (94.2%). Regarding to the LNR, 48.2% (n=91), 29.6% (n=56) and 22.2% (n=42) (22.2) had LNR ≤0.20, 0.21-0.69 and ≥0.70, respectively. Distribution of clinical differences was similar between groups, except for the clinical N stage (N2-N3: 15.4%, 46.4%, 52,3%, respectively; p<0.001). The median follow-up was 7 years. Progression risk was higher in patients with LNR ≤0.20 than 0.20-0.69 and ≥0.70 (HR=1.77, 95%CI:1.21-2.59, p=0.003 and HR=2.22, 95%CI:1.47-3.35, respectively, p<0.001). It was similar for the risk of death (HR=1.78, 95%CI: 1.17-2.70, p=0.007 and HR=2.95, 95%CI:1.91-4.56, respectively, p<0.001). LNR groups were associated to progression events (P=0.02) in contrast to ypN groups (P=0.07). In the multivariate analysis, pre-menopausal status, a higher LNR and ypT with non-complete response were prognostic factors of worse DFS. Only a higher LNR has a negative impact on OS (table 1).
Conclusion: LNR was an independent prognostic factor for TNBC in patients with residual disease with better capability than ypN to predict progression events. LNR should be considered in the risk stratification after NAC among these patients.

Abstract
Abstract
Background: Although chemotherapy is not recommended in low-risk early breast cancer, triple-negative breast cancers (TNBC) have twice risk of recurrence despite an aggressive treatment. In this study we evaluated the role of chemotherapy in the outcome of T1N0 TNBC patients in terms of disease-free survival (DFS) and overall survival (OS).
Methods: We evaluated a retrospective cohort T1N0 TNBC patients diagnosed between 2000 to 2014 at the Instituto Nacional de Enfermedades Neoplasicas (Lima-Peru). Survival rates differences were assessed by Log-rank test and prognostic factors were identified using the Cox proportional hazards model.
Results: We identified 123 T1N0 TNBC patients. The median age was 51 years (range: 28-85), where 38.5% were premenopausal. Thirty-six (29.3%) were pT1a/b and 87 were pT1c (70.7%). ACT was administered more frequently in pT1c patients (74.7% vs 55.6%; P=0.036). Locoregional relapse and distant metastases rates were 8.3% vs 19.5% and 5.6% vs 16.1% for tumors pT1a/b and pT1c, respectively. The median of follow-up was 8.8 years. Independent prognostic factors were pT stage and treatment with ACT. In relation to pT stage, DFS rates were 97% vs 78% (at 5-years) and 97% vs 70% (at 8-years) for pT1a/b vs pT1c patients, respectively (HR=4.8; 95%CI:1.46-17.0; P=0.015). In the other hand, patients treated with ACT had a better outcome with DFS rates to 5-years of 86% vs 74% and 8-years of 81% vs 65% (HR: 0.41, 95%CI: 0.17-0.97, p=0.043). Our study had not statistical power to evaluate benefit of ACT in pT1a/b patients. In cases with pT1c tumors, treatment with ACT was the only factor associated with a better DFS (HR=0.29, 95%CI: 0.11-0.77, p=0.012). Because the low mortality in our cohort, OS was not evaluable.
Conclusions: Treatment with adjuvant chemotherapy reduces the recurrence risk in 71% among pT1cN0 TNBC.

Abstract
Abstract
Background: Triple-negative breast cancer (TNBC) is characterized by being a heterogeneous disease with different risk factors and poor survival rates. TNBC have a higher prevalence in the Peruvian population (21.3%) than in Caucasian groups. Our study aims to determine the outcome and identify prognostic factors in Peruvian women with TNBC.
Methods: We retrospectively analyzed TNBC patients treated at the “Instituto Nacional de Enfermedades Neoplasicas” between 2000 and 2014. Survival rates and differences were calculated by the Kaplan-Meier method and Log-rank test, respectively. With the Cox regression, in univariate and multivariate analysis, we identified prognostic factors in for our TNBC population.
Results: In total, 2007 patients were diagnosed.The mean age was 50 years (range: 19-95 years); 44.8% were premenopausal and 26.2% had obesity at diagnosis. A family history of breast and/or ovarian cancer was present in 266 (28.9%) patients. Regarding the clinical-pathological features, 1860 (93.5%) had ductal invasive carcinoma and 1024 (51.6%) patients were in Stage (S) III. Local relapse and distant metastasis affected to 34.5% and 51.4% of our patients, respectively. Lung (14.5%) and bone (9.7%) were the most frequent sites of metastasis. The median follow-up was 9 years. The 5 and 10 yrs DFS/OS rates are shown in table 1. In the multivariate analysis, adjuvant chemotherapy (ACT) (HR: 0.60, 95%CI: 0.44-0.82, p=0.001) and radiotherapy (RT) (HR:0.72, 95%CI:0.55-0.93, p=0.014) were associated with a reduced risk of recurrence, while nodal involvement were associated to a high recurrence risk. Factors associated to a reduction in the risk of death were ACT (HR:0.73, 95%CI:0.61-0.88, p=0.001), RT (HR: 0.70, 95%CI: 0.60-0.92, p<0.001), and Neoadjuvant CT (HR: 0.61, 95%CI: 0.51-0.73, p<0.001); in contrast, a NLR≥3 (HR:1.60,95%CI: 1.36-1.87, p<0.001), N stage were associated with a higher risk of death.
Conclusions: Sociodemographic features of Peruvian patients with TNBC resemble other populations; however, our population is diagnosed at more advanced clinical stages, hence DFS and OS were lower than international reports while prognostic factors were similar to previous studies.

Abstract
Glioblastoma (GB) is the most common brain malignancy and accounts for over 50% of all high-grade gliomas. Radiotherapy (RT) with concomitant and adjuvant temozolomide (TMZ) chemotherapy is the current standard of care for patients with newly diagnosed GB up to age 70. Recently, a new standard of care has been adopted for elderly patients (≥ 65 years) based on short course of RT and TMZ. Several clinically relevant molecular markers that assist in diagnosis and prognosis have recently been identified. The treatment for recurrent GB is not well defined, and decision-making is usually based on prior strategies as well as several clinical and radiological factors. The presence of neurologic deficits and seizures can significantly impact quality of life.

Abstract
Congenital knee dislocation is an infrequent condition with unknown etiology. In some cases it occurs as an isolated condition, while in others it coexists with associated conditions or syndromes. The treatment of congenital knee dislocation is driven by the severity and flexibility of the deformity. The literature includes from serial casting or the Pavlik harness to quadriceps tendon plasty or femoral osteotomies. We report herein the case of a congenital dislocation treated with serial casting with a good outcome.

Abstract
The cause of familial isolated pituitary adenomas (FIPA) remains unknown in a high percentage of cases, but the AIP gene plays an important role in the etiology. The aim of the study is to describe a family with FIPA syndrome and the results of genomic studies. A 16-year-old man had a giant prolactinoma resistant tomedical treatment with delayed growth and pubertal development. His mother had been previously diagnosed with a nonfunctioning pituitary macroadenoma. Transsphenoidal endoscopic resection was performed and a genetic study revealed a heterozygous mutation in exon 6: 974G>A (p.Arg325Gln). Because the AIP gene is a tumor suppressor gene, we searched for loss of heterozygosity within the AIP gene by amplifying exon 6 from tumor tissue of the patient. In the electropherogram, only the A allele was amplified (hemizygous state), indicating loss of the normal allele. We report a Spanish family with FIPA in whom a mutation in the AIP gene previously unreported in a familiar context was identified.

Abstract
We have studied the diversity of culturable halophilic Archaea at Rambla Salada, Murcia (south-eastern Spain). We made 8 samplings at different places in this habitat during the years 2006 and 2007 and isolated a total of 49 strains, which were identified by means of phenotypic tests and the hypervariable V1-V3 region of the 16S rRNA gene sequences (around 500 bp). The ribosomal data showed that the isolates belonged to 12 genera within the Halobacteriaceae family, with Haloferax and Natrinema being the most abundant. Five strains showed less than 97% sequence identity with validly described species and may well represent new taxa. All the strains grew best with around 25% w/v salts, required high concentrations of NaCl and magnesium and produced red to pink colonies. They were facultative anaerobes with both respiratory and fermentative metabolisms. The diversity of the archaeal community was analysed with the MOTHUR package. We identified 14 OTUs at the 3% genetic distance level and found quite high diversity. Rarefaction curves of richness estimators and diversity indices demonstrated that our collection of isolates represented the archaeal community at Rambla Salada that can be isolated under the conditions used in this work. This is the first report to be published on the culturable archaea at Rambla Salada, an area of considerable ecological interest.

Abstract
Bacillary angiomatosis is a recently described infectious disease that usually affects immunosupressed hosts with a previous history of contact with cats. We report a rare case of bacillary angiomatosis in an immunocompetent 59-year-old woman with no history of previous exposure to cats, and atypical clinical features (fever and subcutaneous nodules with ulceration on the left ankle). Histopathology of the lesion showed extensive ulceration and reactive tumor-like vascular proliferation of the blood vessels with swollen endothelial cells and an inflammatory infiltrate including neutrophils and lymphocytes in the dermis and subcutis. Staining with the Warthin-Starry method demonstrated the presence of clustered bacilli located in the extracellular matrix adjacent to the proliferating endothelial cells. Diagnosis was confirmed with the detection of Bartonella spp. DNA in the affected skin and in bone marrow using polymerase chain reaction.

Abstract
e19072 Background: The gene expression profile in peripheral blood samples from lung cancer patients is a potential predictor to treatment response. Methods: The study has been developed using 10 healthy volunteers as the control group and 10 lung cancer patients (stage IV). Written informed consent was obtained being the protocol approved by the local Clinical Research and Ethics Committee. Peripheral blood samples were obtained from lung cancer patients before (T0) and after treatment (T15d). RNA from peripheral blood samples was extracted and purified selecting 28S/18S ratios>1.5 to obtain cDNA and cRNA for hybridization of the 20,000 genes included in Human 20K CodeLink. An array from each participant was obtained in duplicate. For each array, 2 μg of cRNA was compared to 2 μg of healthy cRNA.. Significant genes were found using Significance Analysis of Microarrays which uses repeated permutations of the data. Results: The selected genes were expressed >3-fold with a false discovery rate =0.05. Before treatment (T0) when patients were compared to healthy volunteers there was an increase in the expression of: histone 1 H4c, transforming growth factor beta 2, endothelial cell growth factor 1 (platelet-derived), glucose-6-phosphatase catalytic 2, Relaxin 3 receptor 1, Insulin-like growth factor binding protein 2, RAS-like family 11 member B, and ELK4. After treatment (T15d), when each lung cancer patient's results were compared to their own before treatment results (T0), there was an increase in the expression of: Bcl2, myosin light polypeptide 4; interferon alpha-inducible protein 27; interferon gamma receptor 1; RASSF5, ARHGEF6, IGFBP5, tumor protein p53 inducible nuclear protein 1, peroxisome proliferative activated receptor gamma. Conclusions: The data presented identifies biologically relevant over-expressed genes in lung cancer. A validation of these results and the analysis of the genes that identify patients who will respond positively to erlotinib treatment is being carried out.

Abstract
14041 Background: Preoperative CT improves survival in esophageal cancer. 50% of patients (pts) do not respond to cisplatin+5-FU (C+F). The reduction of fluorodeoxyglucose uptake after 14 days (d) of CT predicts clinical response (rsp). Our objective was to measure the rsp (rsp) rate after CT adjusted according to PET rsp. Methods: Eligible pts were ≥ stage II esophageal cancer and able to tolerate CT. By adjusting CT according to PET rsp, we expected an increase of rsp rate by 25%. Taking into account a confidence level of 90%, an error β of 20% and a minimal error of 15% (even with such a high error rate the data will exceed the standard results), we calculated a sample size of 23 pts. All underwent esophagoscopy, computed tomography and PET scan prior to C (100mg/m2 d1) +5-FU (1,000mg/m2 d1–5). If PET rsp after first cycle (uptake decreased ≥ 35%), we continued up to third C+F cycle, then if endoscopy rsp: C+F + concurrent radiation only if stage II or III. If no endoscopy rsp, surgery only if stage II or III. On the other hand, if the pts had no rsp in PET after first C+F cycle they continued with 2 cycles of docetaxel (35mg/m2 d 1 & 8) and irinotecan (50mg/m2 d 1 & 8) (D+I) every 21 d and then if endoscopy rsp: radiation + docetaxel only if stage II or III. If no endoscopy rsp, surgery. Results: Since 2/04, 23 pts have been enrolled. Location: 2 cervical, 4 upper thoracic, 7 mid-thoracic, 10 GE junction. PET stage: 7 IIA, 6 IIB, 2 III, 2 IVA, 6 IVB. Up-staging with PET in 6 pts, down-staging in 4 pts. Histology: 10 Adenocarcinoma, 13 squamous carcinoma. Improved swallowing function: from a total of 12 PET responders, 9 had a clinical rsp after C+F, 3 did not. From 11 PET non-responders, 7 had a clinical rsp after D+I, 4 did not. Global clinical rsp = 16/23 (70%). Endoscopy rsp (frequent inaccuracy by overstaging): from a total of 12 PET responders, 6 had a clinical rsp after C+F, 6 did not. From 11 PET non-responders, 7 had a clinical rsp after D+I, 4 did not. Global clinical rsp = 13/23 (57%). Conclusion: Our results suggest that it is possible to significantly increase the percentage of pts who respond to induction CT adjusted according to PET in esophagogastric cancer before concurrent chemoradiotherapy or esophagectomy, or both.

Abstract
BACKGROUND Decreased metabolic activity in the prefrontal cortex during cognitive activation is a recurrent finding and a likely functional marker of schizophrenia. AIMS To investigate the occurrence of hypofrontality in patients with first-episode psychosis, with or without evolution to schizophrenia. METHOD We used fluorodeoxyglucose positron emission tomography during the performance of an attention task and magnetic resonance imaging to study the dorsolateral prefrontal region in 13 men with a first episode of psychosis. Data from patients who progressed to schizophrenia were compared with those of patients who did not meet criteria for this diagnosis after 2 years. RESULTS Patients who developed schizophrenia demonstrated a significant hypofrontality in the dorsolateral prefrontal cortex in comparison with the non-schizophrenia and control groups. CONCLUSIONS Our results suggest that hypofrontality could be a marker of schizophrenia at the time of the first psychotic episode, in agreement with neurodevelopmental theories of schizophrenia.

Abstract
AIMS Recombinant Aspergillus nidulans sVAL040, capable of synthesizing and secreting glucose oxidase derived from Aspergillus niger was used to study the influence of pH and carbon source on enzyme production. METHODS AND RESULTS Glucose oxidase gene (goxC) was expressed under transcriptional regulation by using the promoter of A. nidulans xlnB gene (encoding an acidic xylanase). A maximum specific glucose oxidase activity of approx. 10 U mg(-1) protein and a maximum volumetric productivity of 29.9 U l(-1) h(-1) were obtained at pH 5.5, after 80 h of growth by using xylose as inducer. Enzyme volumetric productivity increased when xylans were used instead of xylose; however, specific glucose oxidase activity did not differ significantly. CONCLUSIONS Specific GOX activity obtained at pH 5.5 are two to three times more than those previously described for goxC multicopy transformants of A. nidulans. Xylans were a more powerful inducer than xylose although fungal growth was lower when the polymers were used. SIGNIFICANCE AND IMPACT OF THE STUDY The obtained results by using xlnB promoter in A. nidulans could be useful in improving heterologous enzyme production by using genetic- and process-engineering strategies.

Abstract
The distribution of cells containing lysozyme, S-100 protein, CD3, CD4, CD8, major histocompatibility complex class II antigen and immunoglobulin G (IgG) was analysed in the bronchus-associated lymphoid tissue (BALT) of goats naturally infected with three Mycoplasma species. This study included the immunohistochemical characterization of the pneumonic lesions of 18 goats (3-5 months old) infected with one of the following Mycoplasma species: M. mycoides ssp. mycoides, Large Colony type (goats no. 1-6), M. mycoides ssp. capri (goats no. 7-12) and M. capricolum ssp. capricolum (goats no. 13-18). Microscopically, infected animals showed a moderate broncho-interstitial pneumonia, characterized by lymphoid hyperplasia of the BALT and infiltration of mononuclear cells in the alveolar walls and airways. The main cellular type in the BALT was represented by CD3+ T lymphocytes, and the ratio of CD4+:CD8+ cells was > 2. The BALT showed large germinal centres mainly composed of IgG+ B lymphocytes, with numerous S-100+ follicular dendritic cells. The presence of follicular dendritic cells confirmed the high degree of organization of this lymphoid tissue. The immunohistochemical results showed that activated T lymphocytes, particularly in the CD4 subset, and IgG+ B cells, play a major role in the immune response of the caprine lung infected with these species of mycoplasmas.

Abstract
The new platelet antiaggregant Triflusal or 2-acetoxy-4-trifluoromethylbenzoic acid presents a structural analogy to acetylsalicylic acid (ASA). Alkaline hydrolysis of triflusal was studied in the presence and absence of cationic micelles of N-cetyl-N-ethyl-N,N-dimethylammonium bromide (CDEABr) at different KOH concentrations and different temperatures (25, 30, and 37 degrees C) using a spectrophotometric method. The influence of potassium bromide concentration upon alkaline hydrolysis at 25 degrees C is also discussed. At constant [KOH] pseudofirst-rate constant (k(obs)) decreased with increasing [CDEABr] at concentrations greater than the CMC and also decreased with increasing [KBr] at constant [KOH] and [CDEABr]. To explain the effect of cationic micelles of CDEABr upon alkaline hydrolysis, the pseudophase ion exchange model was used. The values of the micellar properties such as the critical micelle concentration, the degree of micellar ionization and the neutralized fraction of the head group obtained by conductivity measurements were determined previously.

Abstract
PURPOSE We assume that desmopressin decreases nocturnal urine output of the enuretic child. The aim of this study is to evaluate the efficacy of desmopressin plus oxybutynin and to define urodynamic pattern in children with bladder hyperactivity partially-responders to oxybutynin alone (in which nocturnal enuresis persists in spite of bladder stability). METHODS 48 enuretic patients with urodynamically confirmed bladder hyperactivity were enrolled in the prospective study. All patients were treated with oxybutynin, 0.3-05 mg/Kg/day orally, and bladder therapy, for six months. At the end of this period, patients with excellent response (cessation of nocturnal and diurnal symptoms) was designed as group I (28 children, 58%); patients with partial response (persistence of nocturnal enuresis) as group II (19 children, 40%); and patients non-responders as group III (1 patient, excluded because of no completion of treatment). After six months patients were assessed by standardized urodynamic study. Group II patients were treated with combined therapy, desmopressin-20 mcg/day-plus oxybutynin, for six months. Group I patients served as controls. RESULTS The differences between mean bladder accommodation and mean voiding pressure in patients with excellent response and partially response to oxybutynin were statistically significant. After combined therapy 18 of 19 patients (95%) of group II became group I. CONCLUSIONS The efficacy of desmopressin plus oxybutynin is confirmed in patients with low final accommodation (< 3 ml/cm H2O) and high voiding pressure (> 70 cm H2O). Combined therapy can be a good choice of treatment in children with bladder hyperactivity with partial response to oxybutynin alone.
