Abstract
Background The existence of a cross-talk between peritumoral adipocytes and cancer cells has been increasingly investigated. Several studies have shown that these adipocytes protect tumor cells from the effect of anticancer agents. Methods To investigate a potential protective effect of adipocyte-conditioned medium on HER2 positive breast cancer cells exposed to tyrosine kinase inhibitors (TKI) such as lapatinib, we analyzed the sensitivity of HER2 positive breast cancer models in vitro and in vivo on SCID mice in the presence or absence of adipocytes or adipocyte-conditioned medium. Results Conditioned medium from differentiated adipocytes reduced the in vitro sensitivity of the HER2+ cell lines BT474 and SKBR3 to TKI. Particularly, conditioned medium abrogated P27 induction in tumor cells by lapatinib but this was observed only when conditioned medium was present during exposure to lapatinib. In addition, resistance was induced with adipocytes derived from murine NIH3T3 or human hMAD cells but not with fibroblasts or preadipocytes. In vivo studies demonstrated that the contact of the tumors with adipose tissue reduced sensitivity to lapatinib. Soluble factors involved in this resistance were found to be thermolabile. Pharmacological modulation of lipolysis in adipocytes during preparation of conditioned media showed that various lipolysis inhibitors abolished the protective effect of conditioned media on tumor cells, suggesting a role for adipocyte lipolysis in the induction of resistance of tumor cells to TKI. Conclusions Overall, our results suggest that contact of tumor cells with proximal adipose tissue induces resistance to anti HER2 small molecule inhibitors through the production of soluble thermolabile factors, and that this effect can be abrogated using lipolysis inhibitors.

Abstract
Background:Cardiac involvement in systemic sclerosis (SS) is common and one of the leading causes of mortality (up to 31%). Usually, it appears early and in a silent way. It can affect any cardiac structure and present with various manifestations. Cardiac disease worsens the prognosis and increases mortality, so it should be kept in mind in these patients.Objectives:Study the prevalence of arrhythmias in patients with SS, not affected with pulmonary arterial hypertension (PAH) or other cardiac diseases, and establish its association with left ventricular (LV) dysfunction and heart dysautonomia (HD), as well as with other variables that could predict the development of this complication.Methods:Prospective study of a cohort of patients with SS, excluding those with heart disease, PAH or cardiovascular risk factors. All underwent a clinical assessment, blood test with cardiac biomarkers, electrocardiogram (ECG), Holter 24h (HLT) and echocardiogram (TTE), interpreted by an expert cardiologist blind about the patients. Arrhythmias were classified as clinically significant arrhythmias (CSA) or clinically nonsignificant arrhythmias (CNSA) by ECG and HLT. LV diastolic dysfunction (LVDD) was defined as E/e’> 8, LV systolic dysfunction (LVSD) as a global longitudinal strain <20% and HD as a SDNN <100ms. Demographic, clinical and biological data were collected. A follow-up was performed at 6.2 ± 0.9 years. Statistical analysis was performed using SPSS 23 IBM®.Results:36 patients were included: age 56.7 ± 12.3 years (y), male / female 35/1, disease duration 7 ± 4.1 y. 66% belonged to the limited SS subtype, 66.6% were anti-centromere+, 25% anti-topoisomerase, 2.7% anti-PM/Scl and 2.7% anti-RNA polymerase III+. Raynaud was present in a 100%, telangiectasia in 55.6% and interstitial lung disease in 36.1%. The modified Rodnan skin score (mRSS) was ≤ moderate (0-29 points) in 55.6%; 27.8% had presented digital ulcers that required prostaglandins.27.8% had LVDD, 22% LVSD, 11.1% LVDD + SD and 16.7% HD. 50% (18/36) of patients had ECG alterations, of which 44% corresponded to CSA (Table 1) and, 55.6% (20/36) HLT alterations, of which 75% were CSA (Table 2). 3/36 patients had both HLT and ECG CSA. In 1 patient, impaired LV ejection fraction was detected; in none, valvular disease. 38.8% had elevated NT-proBNP and 13.9% troponin T (TnT). No correlation was found between any parameters and CSA.Table 1.ECG abnormalities.*CSA.Alterations# PatientsMajorComplete Left Bundle Branch Block (BBB)*1MinorAbnormal QRS prolongation in precordial leads1Nonspecific ST-T wave changes3Incomplete Left BBB*3Incomplete Right BBB*4OtherQT prolongation11Table 2.HLT alterations.*CSA.AlterationsSubtype# PatientsSupraventricular ExtrasystolesUncommon7Frequent*3Mono/Polymorphic0Nonsustained Supraventricular Tachycardia*7Ventricular ExtrasystolesBenign4No Benign*4Doublets1Two Morphologies2Accelerated Idioventricular Rhythm11st-degree Atrioventricular Block1Sinus Tachycardia2A correlation was found between mRSS and DLCO (p=0.002), DLCO and digital ulcers (p=0.001), and mRSS and digital ulcers (p=0.005). A correlation was also found between elevated NT-proBNP and TnT (p=0.006) and between elevated NT-proBNP and LVDD (p=0.049).At follow-up after 6.2 ± 0.9 y, 2 patients had died: 1 of neoplasia and 1 of severe biventricular dysfunction 5.2 y after the study.Conclusion:Our data confirm a high prevalence of ventricular arrhythmias and left dysfunction in patients with SS, without heart disease, cardiorespiratory symptoms or HAP, being up to 75% of the arrhythmias CSA. The lack of correlation between CSA and LVSD or DD indicates that arrhythmias could be due, not only to a supposed structural alteration of the myocardium, but to a primary and early cardiac involvement in SS. In addition, the lack of correlation between CSA in ECG and HLT reinforces the importance of a complete cardiac evaluation in these patients to rule out silent cardiac involvement.Disclosure of Interests:LILIAN LÓPEZ-NÚÑEZ: None declared, Irene Carrión Barberà Grant/research support from: I received a grant from the Spanish Rheumatology Foundation (FER) and laboratories KERN PHARMA for a brief stay abroad., Isabel Padró: None declared, Lluis Molina: None declared, Ana Pros: None declared

Abstract
Marine sediments represent an important sink of harmful petroleum hydrocarbons after an accidental oil spill. Electrobioremediation techniques, which combine electrokinetic transport and biodegradation processes, represent an emerging technological platform for a sustainable remediation of contaminated sediments. Here, we describe the results of a long-term mesocosm-scale electrobioremediation experiment for the treatment of marine sediments contaminated by crude oil. A dimensionally stable anode and a stainless-steel mesh cathode were employed to drive seawater electrolysis at a fixed current density of 11 A/m2. This approach allowed establishing conditions conducive to contaminants biodegradation, as confirmed by the enrichment of Alcanivorax borkumensis cells harboring the alkB-gene and other aerobic hydrocarbonoclastic bacteria. Oil chemistry analyses indicated that aromatic hydrocarbons were primarily removed from the sediment via electroosmosis and low molecular weight alkanes (nC6 to nC10) via biodegradation.

Abstract
BACKGROUND Oropharyngeal sensory impairment is a potential target to treat swallowing dysfunction in patients with oropharyngeal dysphagia (OD). AIM To assess the therapeutic effect of stimulating oropharyngeal sensory afferents with TRPV1, TRPA1, or TRPM8 agonists vs increasing bolus viscosity in older and neurologic patients with OD by comparing four studies of similar experimental design. METHODS Swallow function of 142 older patients with impaired safety of swallow at nectar ([50-350] mPa·s) viscosity was evaluated with videofluoroscopy (VFS) while treated with TRPV1 (150 μmol/L), TRPV1/A1 (150 μmol/L and 1 mmol/L), or TRPM8 (1 mmol/L or 10 mmol/L) agonists or modified starch (MS) at spoon thick viscosity (>1750 mPa·s). RESULTS TRPV1 stimulation with capsaicinoids reduced penetrations by 50%, pharyngeal residue by 80%, and LVC time by 24.38% and increased bolus velocity by 36.51%. TRPV1/A1 stimulation with piperine reduced penetrations by 56.32%, LVC time by 25.55% and increased bolus velocity by 23.63%. TRPM8 stimulation with menthol 1 mmol/L reduced penetrations by 37.5% while 10 mmol/L reduced LVC time by 18.44%. Thickeners reduced penetrations by 77.11%, but increased pharyngeal residue by 19.89%, delayed LVC by 41.73%, and reduced bolus velocity by 13.44%. CONCLUSION Natural capsaicinoids have a stronger therapeutic effect on VFS signs and swallow response by stimulating TRPV1 than TRPV1/A1 or TRPM8 agonists. While TRP stimulants increased bolus velocity and reduced swallow response times, thickeners reduced bolus velocity and further delayed the swallow response. This study sets the bases to develop new pharmacologic strategies for older patients with OD, moving away from compensation toward the recovery of swallow function.

Abstract
Morphometric and genetic analyses confirmed the first records of the West African seahorse Hippocampus algiricus at Gran Canaria Island (north-east Atlantic Ocean), and also the first evidence of interspecific hybridization in seahorses. These results provide additional data on the distribution of H. algiricus that may help to establish future conservation strategies, and uncover a new potential sympatric scenario between H. algiricus and Hippocampus hippocampus.

Abstract
BACKGROUND We conducted a phase 1 trial in patients with locally advanced cervical cancer by injecting 0.5 ml of the CK2-antagonist CIGB-300 in two different sites on tumours to assess tumour uptake, safety, pharmacodynamic activity and identify the recommended dose. METHODS Fourteen patients were treated with intralesional injections containing 35 or 70 mg of CIGB-300 in three alternate cycles of three consecutive days each before standard chemoradiotherapy. Tumour uptake was determined using (99)Tc-radiolabelled peptide. In situ B23/nucleophosmin was determined by immunohistochemistry. RESULTS Maximum tumour uptake for CIGB-300 70-mg dose was significantly higher than the one observed for 35 mg: 16.1 ± 8.9 vs 31.3 ± 12.9 mg (P = 0.01). Both, AUC24h and biological half-life were also significantly higher using 70 mg of CIGB-300 (P < 0.001). Unincorporated CIGB-300 diffused rapidly to blood and was mainly distributed towards kidneys, and marginally in liver, lungs, heart and spleen. There was no DLT and moderate allergic-like reactions were the most common systemic side effect with strong correlation between unincorporated CIGB-300 and histamine levels in blood. CIGB-300, 70 mg, downregulated B23/nucleophosmin (P = 0.03) in tumour specimens. CONCLUSION Intralesional injections of 70 mg CIGB-300 in two sites (0.5 ml per injection) and this treatment plan are recommended to be evaluated in phase 2 studies.

Abstract
In cattle, ~40% of embryonic loss occurs in the period from Day 8 to Day 16 of pregnancy. A significant proportion of embryo loss may be due to inadequate circulating progesterone (P4) concentrations. Low P4 concentrations have also been implicated as a causative factor in the low pregnancy rates (PR) observed in high-yielding dairy cows. Administration of hCG during the early luteal phase stimulates hypertrophy of the original corpus luteum (CL) and, depending on the day of administration, induces ovulation of the first-wave dominant follicle and formation of a functional accessory CL, which increases circulating P4 concentrations. The aim of this study was to examine whether administration of hCG on Day 2 or Day 5 after oestrus after timed AI (TAI) would lead to an increase in pregnancy rates in dairy cattle. Lactating Holstein cows (n = 194) from 12 commercial dairy herds in Southern Spain (37.8833° N, 4.7667° W) with an average milk production at 37.8 L/cow per day and typically with a PR to first AI of ~30% were randomly assigned based on their body condition score (2.65 ± 0.05; mean ± SEM), parity (2.60 ± 0.09), and days in milk (75.06 ± 0.63) to 1 of 3 treatments and administered a single intramuscular injection of 3000 IU of hCG (4 mL of Veterin Corion) either (1) on Day 2 = 36 h after TAI (n = 65; hCG2 group), (2) Day 5 = 108 h after TAI (n = 64; hCG5 group), or (3) 4 mL of saline on Day 2 = 36 h after TAI (n = 65; control group). Cows were synchronized using a 7-day Ovsynch TAI protocol that included a P4-releasing intravaginal device (PRID DELTA 1.55 g). First, gonadotropin-releasing hormone (Cystorelin 100 mg) treatment was administered at PRID insertion (Day 0) followed by 25 mg Dinoprost (prostaglandin F2α: Enzaprost T) on Day 7 at PRID withdrawal. Then, 56 h later, the second gonadotropin-releasing hormone (100 mg) treatment was administered and all cows were inseminated 16 h later. Pregnancy was diagnosed by ultrasonography 28 to 32 days after TAI. Logistic regression model and chi-squared test were used to analyse data. Pregnancy rate to AI was significantly higher in the hCG2 and hCG5 groups than in the control group (43.1 and 45.3%, v. 27.7%; P < 0.05). A treatment-by-parity interaction was observed; while pregnancy rate for primiparous cows was not affected by treatment, multiparous cows from the hCG2 group had greater pregnancies per AI than those in the control group (47.2% v. 21.1%, respectively; P < 0.05). In conclusion, these preliminary results suggest that hCG administration on Day 2 and 5 after oestrus increases PR at first postpartum AI in Holstein cows. In addition, hCG on Day 2 increases the fertility in multiparous cows.This study was funded by the Spanish Ministry of Science and Innovation (AGL2012–37510) and partially supported by Ceva Salud Animal S.A., Spain – synchronization protocol and DFV, Spain – hCG treatments.

Abstract
Since 2009, the largest reported outbreak of leishmaniasis by Leishmania infantum in Europe was reported in Fuenlabrada, Spain. In our hospital, 90 adults with localized leishmanial lymphadenopathy (LLL) or visceral leishmaniasis (VL) were treated during this outbreak; 72% were men, and the mean age was 46.2 years (range 15-95 years). A total of 17 cases (19%) were LLL, an atypical form with isolated lymphadenopathies without other symptoms. All LLL cases occurred in immunocompetent subjects, and only one subject (6%) was a native of sub-Saharan Africa. Diagnosis was performed by fine needle aspiration cytology of the lymphadenopathy. Serology was negative in 38%. LLL outcomes at 6 months were benign, even with doses of liposomal amphotericin B that were often lower (10 mg/kg) than those recommended for VL in Mediterranean areas. A total of 73 subjects (81%) presented with typical VL; 66% of this group were immunocompetent, and 50% of those who were immunocompetent were descendants of natives of sub-Saharan Africa. The rK39 test and polymerase chain reaction were the most useful tests for confirmation of the diagnosis. An initial response to treatment was observed in 99% of cases, and relapses occurred in 14% of cases. Leishmaniasis should be included in the differential diagnosis of isolated lymphadenopathies in endemic areas. LLL could be considered a more benign entity, one different than VL, and less aggressive management should be studied in future investigations.

Abstract
JAK 2 mutation is the molecular event responsible for 95% of polycythemia cases and 50% of thrombocythemia vera and myelofibrosis cases. It can be used as a tool for the diagnosis of myeloproliferative disorders. We report a case illustrating the fact that a negative result does not definitively eliminate the diagnosis. A 40-year old woman, with a medical history of familial deep vein thrombosis, developed thrombosis of the inferior vena cava with extension to the suprahepatic veins and pulmonary embolism. No constitutional or acquired thrombophilia was diagnosed; search for JAK 2 mutation was negative. The patient was treated with fluindione. Five years later, she relapsed with popliteo-femoral and vena cava deep vein thrombosis. The etiological work-up included a PET scan which revealed diffuse uptake in bones and suspected neoplasic bone marrow invasion. Progenitor cell cultures were positive and JAK 2 mutation was confirmed. The bone marrow aspirate had the cytologic appearance of a myeloproliferative disorder. This case illustrates the fact that JAK 2 mutation can be identified several years after onset of a latent myeloproliferative disorder. Cases with a high clinical likelihood should lead to renewed search for this mutation. Secondary discovery of this mutation can be explained by a higher proportion of mutation expressing clones.

Abstract
Conventional polymerase chain reaction (PCR) in respiratory samples does not differentiate between Pneumocystis pneumonia (PCP) and Pneumocystis jirovecii (Pj) colonization. We used Pj real-time quantitative PCR (qPCR) with the objective to discriminate PCP from Pj colonization in immunocompromised patients. All positive Pj qPCR [targeting the major surface glycoprotein (MSG) gene] obtained in respiratory samples from immunocompromised patients presenting pneumonia at the Grenoble University Hospital, France, were collected between August 2009 and April 2011. Diagnoses were retrospectively determined by a multidisciplinary group of experts blinded to the Pj qPCR results. Thirty-one bronchoalveolar lavages and four broncho aspirations positive for the Pj qPCR were obtained from 35 immunocompromised patients. Diagnoses of definite, probable, and possible PCP, and pneumonia from another etiology were retrospectively made for 7, 4, 5, and 19 patients, respectively. Copy numbers were significantly higher in the “definite group” (median 465,000 copies/ml) than in the “probable group” (median 38,600 copies/ml), the “possible group” (median 1,032 copies/ml), and the “other diagnosis group” (median 390 copies/ml). With the value of 3,160 copies/ml, the sensitivity and specificity of qPCR for the diagnosis of PCP were 100 % and 70 %, respectively. With the value of 31,600 copies/ml, the sensitivity and specificity were 80 % and 100 %, respectively. The positive predictive value was 100 % for results with more than 31,600 copies/ml and the negative predictive value was 100 % for results with fewer than 3,160 copies/ml. qPCR targeting the MSG gene can be helpful to discriminate PCP from Pj colonization in immunocompromised patients, using two cut-off values, with a gray zone between them.

Abstract
Pseudomonas putida DOT-T1E is an organic solvent tolerant strain capable of degrading aromatic hydrocarbons. Here we report the DOT-T1E genomic sequence (6 394 153 bp) and its metabolic atlas based on the classification of enzyme activities. The genome encodes for at least 1751 enzymatic reactions that account for the known pattern of C, N, P and S utilization by this strain. Based on the potential of this strain to thrive in the presence of organic solvents and the subclasses of enzymes encoded in the genome, its metabolic map can be drawn and a number of potential biotransformation reactions can be deduced. This information may prove useful for adapting desired reactions to create value-added products. This bioengineering potential may be realized via direct transformation of substrates, or may require genetic engineering to block an existing pathway, or to re-organize operons and genes, as well as possibly requiring the recruitment of enzymes from other sources to achieve the desired transformation.

Abstract
Erysipelothrix rhusiopathiae septicemia, associated with an increased mortality of captive psittacines in a mixed-species aviary, was diagnosed by histopathology, Gram staining, bacterial culture and sequencing, immunohistochemistry, and real-time polymerase chain reaction (PCR). Over a period of 23 days with no premonitory signs, 2 rainbow lorikeets and an eclectus parrot died. Of these birds, one lorikeet and the eclectus were submitted for necropsy. The main pathologic findings were thrombosis (2/2), bacterial embolism/thromboembolism (2/2), necrotizing hepatitis (2/2), necrohemorrhagic myocarditis (1/2), fibrinohemorrhagic and heterophilic visceral coelomitis (1/2), submandibular necrosuppurative dermatitis with necrotizing vasculitis and bacterial and fungal thromboembolism (1/2), and locally extensive rhabdomyonecrosis with bacterial embolism (1/2). Intralesional bacteria were positive by Gram staining and immunohistochemistry in both cases. E. rhusiopathiae was isolated by routine bacterial culture from the liver of the lorikeet, which was also positive by real-time PCR. This report is one of the rare descriptions of erysipelas in psittacines, and to the authors’ knowledge, it appears to be the first in the described species using immunohistochemistry and real-time PCR on avian paraffin-embedded tissues for the diagnosis.

Abstract
Quantitative electron tomography is proposed to characterize porous materials at a nanoscale. To achieve reliable three-dimensional (3D) quantitative information, the influence of missing wedge artifacts and segmentation methods is investigated. We are presenting the "Discrete Algebraic Reconstruction Algorithm" as the most adequate tomography method to measure porosity at the nanoscale. It provides accurate 3D quantitative information, regardless the presence of a missing wedge. As an example, we applied our approach to nanovoids in La2Zr2O7 thin films.

Abstract
Paraneoplastic neurological syndromes are associated with various cancers. Cerebellar and limbic paraneoplastic manifestations are known to be associated with Hodgkin's disease (HD), but reports of diffuse encephalitis associated with HD are very rare. We report a case of acute severe diffuse encephalitis revealing a HD. Clinical presentation, cerebro-spinal fluid modifications and magnetic resonance imagery data are described. The treatment associated specific chemotherapy and plasma exchange. The neurological status improved dramatically within the first days of treatment, with parallel neoplasm regression. This case stresses the fact that encephalopathy can be the first sign of an undiagnosed extra-cerebral neoplasm.

Abstract
Ustilago maydis is a ubiquitous pathogen of maize and a well-established model organism for the study of plant-microbe interactions. This basidiomycete fungus does not use aggressive virulence strategies to kill its host. U. maydis belongs to the group of biotrophic parasites (the smuts) that depend on living tissue for proliferation and development. Here we report the genome sequence for a member of this economically important group of biotrophic fungi. The 20.5-million-base U. maydis genome assembly contains 6,902 predicted protein-encoding genes and lacks pathogenicity signatures found in the genomes of aggressive pathogenic fungi, for example a battery of cell-wall-degrading enzymes. However, we detected unexpected genomic features responsible for the pathogenicity of this organism. Specifically, we found 12 clusters of genes encoding small secreted proteins with unknown function. A significant fraction of these genes exists in small gene families. Expression analysis showed that most of the genes contained in these clusters are regulated together and induced in infected tissue. Deletion of individual clusters altered the virulence of U. maydis in five cases, ranging from a complete lack of symptoms to hypervirulence. Despite years of research into the mechanism of pathogenicity in U. maydis, no 'true' virulence factors had been previously identified. Thus, the discovery of the secreted protein gene clusters and the functional demonstration of their decisive role in the infection process illuminate previously unknown mechanisms of pathogenicity operating in biotrophic fungi. Genomic analysis is, similarly, likely to open up new avenues for the discovery of virulence determinants in other pathogens.

Abstract
The aim of the study was to determine the association between the amount and the intensity of physical activity (PA) and lipid profile and fitness in pre-menopausal women. A cross-sectional study was conducted, sampling was stratified according to two age groups and two levels of PA, as assessed by the Minnesota Leisure Time PA Questionnaire. Serum lipid profile and sex hormones were measured. The study included 403 women. Total energy expenditure on PA was directly associated with HDL-cholesterol and inversely with atherogenic index. When intensity was analyzed, only moderate PA was associated with a desirable lipid profile. A decrease of 1.59 mg/dL (standard error [SE] = 0.77) and 0.07 units (SE = 0.02) in LDL-cholesterol and atherogenic index, respectively, and an increase of 1.02 mg/dL (SE = 0.34) in HDL-cholesterol were observed per each 100 MET . min/day spent in moderate PA. After adjusting for body fat mass, the association between moderate PA and LDL-cholesterol was no longer statistically significant (regression coefficient = - 1.21; SE = 0.81) whereas the association between moderate PA and atherogenic index (regression coefficient = - 0.05; SE = 0.02) and HDL-cholesterol (regression coefficient = 0.98; SE = 0.35) remained statistically significant. Only vigorous PA was associated with VO2max. VO2max increased 2.35 mL/kg (SE = 0.39) per each 100 MET . min/day spent in vigorous PA. Only moderate PA is associated with a lower LDL-cholesterol and atherogenic index, and higher HDL-cholesterol. The association between PA and LDL is dependent on body fat mass, but the association between PA and HDL is independent of it. Only vigorous intensity PA is associated with fitness.

Abstract
BACKGROUND Polycystic ovary syndrome (PCOS) is a common endocrine disorder in women of reproductive age. The aim of the present study was to investigate the role of CALPAIN-5 (CAPN5) gene in PCOS susceptibility. METHODS We analysed four intronic polymorphisms of the CAPN5 gene in 148 well-characterized women with PCOS and 606 unrelated controls. We performed a case-control study and an intracohort analysis of clinical characteristics associated with PCOS. RESULTS Analysis of haplotypes distribution between PCOS population compared to controls showed a strong deviation (P = 0.00029). The haplotypes GGCA and GGTG were overrepresented in PCOS patients (P = 0.009 and P = 0.001, respectively). In addition, we identified several CAPN5 haplotypes associated with phenotypic differences observed between PCOS patients, such as the presence of obesity (P = 0.02), cardiovascular complications (P = 0.02), familial antecedents of obesity (P = 0.003) and of hypertension (P = 0.007) and type 2 diabetes mellitus aggregation (P = 0.04). CONCLUSIONS These results suggest a role of CAPN5 gene in PCOS susceptibility in humans. Moreover, novel candidate risk alleles have been identified, within CAPN5 gene, which could be associated with important phenotypic and prognosis differences observed in PCOS patients.

Abstract
Moli1901 is a 19 residue polycyclic peptide antibiotic which increases chloride transport and water mobilization in airway epithelium. These properties suggest that it may be a useful treatment for cystic fibrosis (CF). In this study, we used accelerator mass spectrometry (AMS) to quantify Moli1901 following administration of only 0.045 microCi of 14C-Moli1901 per dog. Limits of quantitation of AMS were 0.03 (urine) to 0.3 (feces) ng equiv. Moli1901/g. Administration of 14C-Moli1901 by intratracheal instillation (approximately 100 microg) into the left cranial lobe of the lung of beagle dogs resulted in retention of 64% of the dose in the left cranial lobe for up to 28 days. Whole blood and plasma concentrations of 14C were <5 ng/ml at all times after the dose. Concentrations of 14C in whole blood and plasma declined over the first day after the dose and rose thereafter, with the rise in plasma concentrations lagging behind those in whole blood. During the first 3 days after the dose, plasma accounted for the majority of 14C in whole blood, but after that time, plasma accounted for only 25-30% of the 14C in whole blood. Tissue (left and right caudal lung lobe, liver, kidney, spleen, brain) and bile concentrations were low, always less than 0.25% the concentrations found in the left cranial lung lobe. Approximately 13% of the dose was eliminated in urine and feces in 28 days, with fecal elimination accounting for about 10% of the dose. The data presented here are consistent with that obtained in other species. Moli1901 is slowly absorbed and excreted from the lung, and it does not accumulate in other tissues. Moli1901 is currently in the clinic and has proven to be safe in single dose studies in human volunteers and cystic fibrosis patients by the inhalation route. No information on the disposition of the compound in humans is available. This study in dogs demonstrates the feasibility of obtaining that information using 14C-Moli1901 and AMS.

Abstract
A 33 year old female had febrile aplasia following a first chemotherapy treatment for acute T lymphoid leukaemia. She was transferred to intensive care for acute respiratory distress due to bilateral pneumonia with Stenotrophomonas maltophilia septicaemic shock. After an initial improvement with antibiotic treatment, she developed multiple necrotic cutaneous lesions. A skin biopsy showed the presence of Aspergillus flavus in large quantities in the vascular lumina. Echocardiography revealed a voluminous vegetation on the mitral valve supporting aspergillus endocarditis. Despite antifungal treatment, shock and coma developed rapidly. Cerebral CT scan suggested multiple septic emboli. Within several hours, the scenario progressed towards multiorgan failure leading the death of the patient. Aspergillus endocarditis is exceptional and usually only occurs in immunosuppressed patients. The diagnosis is difficult, and the prognosis is appalling with a mortality greater than 90% despite treatment.

Abstract
Physical activity (PA) is associated with a reduced risk of coronary heart disease, and may favorably modify the antioxidant-prooxidant balance. This study assessed the effects of aerobic PA training on antioxidant enzyme activity, oxidized LDL concentration, and LDL resistance to oxidation, as well as the effect of acute PA on antioxidant enzyme activity before and after the training period. Seventeen sedentary healthy young men and women were recruited for 16 weeks of training. The activity of superoxide dismutase in erythrocytes (E-SOD), glutathione peroxidase in whole blood (GSH-Px), and glutathione reductase in plasma (P-GR), and the oxidized LDL concentration and LDL composition, diameter, and resistance to oxidation were determined before and after training. Shortly before and after this training period they also performed a bout of aerobic PA for 30 min. The antioxidant enzyme activity was also determined at 0 min, 30 min, 60 min, 120 min, and 24 h after both bouts of PA. Training induces an increase in GSH-Px (27.7%), P-GR (17.6%), and LDL resistance to oxidation, and a decrease in oxidized LDL (-15.9%). After the bout of PA, an increase in E-SOD and GSH-Px was observed at 0 min, with a posterior decrease in enzyme activity until 30-60 min, and a tendency to recover the basal values at 120 min and 24 h. Training did not modify this global response pattern. Regular PA increases endogenous antioxidant activity and LDL resistance to oxidation, and decreases oxidized LDL concentration; 30 min of aerobic PA decreases P-GR and B-GSH-Px activity in the first 30-60 min with a posterior recovery.

Abstract
1. Administration of aerosolized, radiolabelled Moli1901 (duramycin, 2622U90), a 19 amino acid polycyclic peptide, to rats resulted in the deposition of high amounts of radiolabel in the respiratory tract, with deposited radiolabel persisting almost unchanged through 7 days after dosing. Little to no radiolabel was present in the bloodstream of these rats. 2. Rats absorbed little radiolabel after p.o. administration, with nearly all of the dose excreted in the faeces by 2 days after dosing. 3. At 7 days following an intravenous dose, rats excreted 54% of the radiolabel in faeces and 5.4% in the urine, with 44% remaining in the carcass, primarily in the liver (33%). 4. Following an intratracheal instillation dose to rats, radiolabel was eliminated from the pulmonary system with a half-life of 64 days. Excretion was almost exclusively via faeces, with an elimination half-life of 52 days. Plasma and blood concentrations in these animals were uniformly <1 ng eq. ml(-1) at all sampling times. 5. Results in mice given intravenous and oral doses were consistent with those observed in rats. 6. Prolonged retention of Moli1901 in pulmonary tissue supports its use in the treatment of respiratory diseases.

Abstract
Gas chromatography with electron capture detector (ECD), nitrogen-phosphorus detector (NPD), and tandem mass spectrometry (MS/MS) was used to identify 36 pesticides, widely used to control various pest and diseases in vegetables, in water after a preconcentration step on C18 cartridges. The recoveries obtained ranged from 70 to 135% at a fortification level of 100 ng/L with relative standard deviations of <36.2%. The limits of detection and quantitation were < or =48 and < or =160 ng/L, respectively. Important advantages of MS/MS over ECD and NPD in the determination of pesticides are also presented. The proposed analytical methodology was applied to the determination of pesticides in groundwater samples from an agricultural area, the Campo de Dalías (Almería, Spain). The most frequently encountered pesticides were endosulfan sulfate and metalaxyl, whereas the pesticide found at the highest concentration was fenamiphos.

Abstract
The physiological roles of insulin and insulin-like growth factors (IGFs) are distinct, with insulin acting to regulate cellular uptake and metabolism of fuels, whereas IGFs promote cell growth, survival and differentiation. The only components of signalling pathways known to be unique to insulin and IGFs are their respective receptors, and even these display substantial structural and functional similarity. Specificity of action in vivo must in part reflect relative levels of receptor expression in different tissues. The extent to which the receptors differ in intrinsic signalling capacity remains unclear, but specificity might in principle arise from differences in ligand-binding mechanism or properties of intracellular domains. To identify ligand binding determinants we expressed receptor fragments as soluble proteins. Both N-terminal domains and a C-terminal peptide sequence from the alpha-subunit are essential for ligand binding with moderate affinity. However, binding of ligand with high affinity and specificity requires higher-order structure. To compare signalling capacities, we constructed chimaeras containing intracellular domains of insulin or IGF receptors fused to the extracellular portion of TrkC. Expression and activation of these chimaeras in cell lines reveals subtle differences in signalling and end-point responses, which may depend on cell background.

Abstract
The aim of the study is to investigate serum lipoproteins abnormalities including low-density lipoprotein (LDL) particle size, and their relationship with other cardiovascular risk factors in men with essential hypertension. Plasma glucose and serum insulin levels during oral glucose tolerance test (OGTT), serum lipoprotein(a), apolipoprotein (apo) A-I. apo B. cholesterol and triglycerides in serum and in lipoproteins, and LDL particle diameter were measured in thirty-eight consecutive newly-diagnosed non-diabetic untreated hypertensive men and 38 healthy male controls. Plasma glucose at baseline, 60 and 120 min during OGTT was significantly higher in patients than controls whereas serum insulin levels did not differ between patients and controls. Serum apo B and triglycerides were significantly raised in patients compared with controls (1.08 +/- 0.17 g/L [mean +/- SD] vs 0.97 +/- 0.22 g/L. p < 0.05, and 1.56 +/- 0.90 mmol/L vs 1.15 +/- 0.57 mmol/L, p < 0.05, respectively). Very-low-density lipoprotein (VLDL) triglycerides and LDL-cholesterol were increased in patients compared with controls (0.89 +/- 0.79 mmol/L and 0.54 +/- 0.35 mmol/L, p < 0.05, and 4.08 +/- 0.85 mmol/L and 3.60 +/- 0.92 mmol/L, p < 0.05, respectively) whereas high-density lipoprotein (HDL) cholesterol was lower in patients compared with controls 0.95 +/- 0.22 mmol/L and 1.07 +/- 0.20 mmol/L, p < 0.05). Adjustment for body mass index, abdominal/hip perimeter ratio and area under the glucose curve did not attenuate the relationship between hypertension and VLDL-triglycerides. Six patients and two controls had a mean LDL diameter < or = 25.5 nm and in the former serum triglycerides ranged from 1.86 mmol/L to 2.37 mmol/L. Mean LDL particle diameter in both patients and controls showed an inverse relationship with log-transformed serum triglycerides (r = - 0.51, p < 0.001 and r = - 0.47, p < 0.005, respectively). Among patients, those with serum triglycerides > or = [corrected] 1.58 mmol/L had a lesser mean LDL diameter than those with triglycerides above this threshold (25.78 +/- 0.47 nm vs 26.30 +/- 0.35 nm, p < 0.001). Higher plasma glucose, serum apo B and LDL-cholesterol as well as the decrease in serum HDL-cholesterol in patients with hypertension are consistent with high coronary heart disease risk. Not only mild hypertriglyceridemia but also high-normal serum triglycerides in themselves or as a surrogate of a predominance of small dense LDL particles in plasma convey an additional risk for cardiovascular disease in hypertensive patients even though routine plasma lipids are within or near normal range.

Abstract
Fever is frequently the only clinical sign of infection in patients with chemo-induced neutropenia. In this setting, empirical administration of broad spectrum antibiotics must be rapid. The aim of this work was to compare, for the first time, cefpirome (CPO) and piperacillin-tazobactam (PT) in a large randomized trial. Two hundred-eight febrile neutropenic episodes (FNE) (> or = 38.5 degrees C and ANC < or = 0.5 giga/l) were treated by randomization, as first line therapy, using either CPO 2 g x 2/day (105 cases) or PT 4 g x 3/day (103 cases), alone (CPO: 15/PT: 15), or plus aminoglycoside (165 cases, CPO: 82/PT: 83) or quinolone (CPO: 2/PT: 2). There were 131 men and 77 women aged between 17 and 83 years (median: 49) who received chemotherapy (n = 160) or allogeneic (n = 10) or autologous (n = 38) stem cell transplantations. Underlying diseases were: acute leukemia (n = 131), lymphoma (n = 33), myeloma (n = 16), solid tumor (n = 8), myeloproliferative disorder (n = 9), chronic lymphoid leukemia (n = 5), aplastic anemia (n = 3), myelodysplasia (n = 3). Distribution of age, neutropenia duration (median: 17 days), underlying disease, and protocol therapy duration (median: 11 days) was comparable in both arms. A microbiologically documented infection (MDI) was evidenced in 57 cases (27%). Bacteria were isolated from blood cultures in 54 cases (Gram positive: 32 cases). Their in vitro susceptibility rates to CPO and PT were not different. Two days after antibiotics initiation, clinical (fever disappearance) and microbiological (culture negativation) success rates (SR) were 62% for CPO versus 61% for PT and 50% versus 55% respectively in case of MDI (p = 0.89). Two deaths and 77 failures were registered. At the end of protocol, SR (no antibiotic change/absence of superinfection) was 59% with CPO versus 50% with PT (p = 0.27) and 53% versus 40% respectively in the 151 cases with neutropenia > or = 10 days (p = 0.17). The occurrence of side effects was similar in both arms. In our hands, the efficacy of CPO and PT was comparable for treating FNE.

Abstract
Echinococcal infestation of the heart is uncommon. We report a case of a 35-year-old man with an hydatid cyst located in distal interventricular septum. Clinical presentation was chest pain and urticaria. Diagnosis was made by echocardiography and magnetic resonance imaging. Surgical resection was performed; the cyst was punctured and its content was drained, hypertonic glucose solution was instilled for sterilization, and it was removed. The patient did well and remains asymptomatic. Diagnosis and ultimate surgical treatment of this disease prevented potentially lethal complications such as cyst rupture with embolic phenomena and anaphylactic shock.
