Abstract
The mechanisms underlying host resistance to Mycobacterium avium subsp. paratuberculosis (MAP) infection are largely unknown. In the current study, we hypothesize that cows with an ability to produce higher levels of interferon-gamma (IFNɣ) might control MAP infection more successfully. To test this hypothesis, IFNɣ production was measured using a specific IFNɣ ELISA kit in avian purified protein derivative (aPPD)-stimulated blood samples collected from 152 Holstein cattle. DNA isolated from peripheral blood samples of the animals included in the study was genotyped with the EuroG Medium-Density Bead Chip, and the genotypes were imputed to whole-genome sequencing. A genome-wide association analysis (GWAS) revealed that high levels of IFNɣ in response to the aPPD were associated with a specific genetic profile (heritability = 0.64) and allowed the identification of 71 SNPs, 40 quantitative trait loci (QTL), and 104 candidate genes. A functional analysis using the 104 candidate genes revealed a significant enrichment of genes involved in the innate immune response and, more specifically, in necroptosis. Taken together, our results define a heritable and distinct immunogenetic profile associated with the production of high IFNɣ levels and with the capacity of the host to lyse MAP-infected macrophages by necroptosis.

Abstract
Different studies carried out in the last three decades on the magnetic susceptibility of the spinel ZnFe2O4 ferrite have revealed the positive character of its Curie–Weiss temperature, contradicting its observed antiferromagnetic behavior which is characterized by a well-defined susceptibility peak centered around the Neel temperature (10 K). Some approaches based on ab initio calculations and mixture of interactions have been attempted to explain this anomaly. This work shows how for very low values of the inversion parameter, the small percentage of Fe atoms located in tetrahedral sites gives rise to the appearance of ferrimagnetic clusters around them. Superparamagnetism of these clusters is the main cause of the anomalous Curie–Weiss behavior. This finding is supported experimentally from the thermal dependence of the inverse susceptibility and its evolution with the degree of inversion.

Abstract
Understanding how we are adapting to climate change in coastal areas is an essential issue in the long-term coastal planning. While most of existing studies focus on mapping the current state of adaptation plans, there is a significant lack of studies on the current implementation of adaptation strategies. This study addresses this challenge by assessing how coastal adaptation is being financed and implemented in Spain. In the absence of a detailed roadmap for implementing the Spanish Strategy for Coastal Adaptation to Climate Change, we have analysed how adaptation has been and is currently being funded; which the rationale for investments along the territory is; how adaptation investments compare to regular coastal protection costs; and assessed when implemented measures are really adaptation ones. Our results show that the financing source clearly conditions the type of measures implemented, with those funded under the Environment Promotion Plan for Climate Change Adaptation (PIMA Adapta initiative) being dominated by classical coastal engineering actions, whereas ecosystem-related actions are mostly funded under the LIFE programme. In territorial terms, the Mediterranean coastal regions present the most important problems under current conditions and attract most of the funding. Most of the funded actions have been designed to solve current coastal problems, and although they indirectly contribute to adaptation by improving the coastal base status, they are not specifically designed for climate change. This misuse of the concept of adaptation measure will tend to the society to be overconfident about adopted actions whereas we are not progressing to real adaptation. To overcome this risk, it is necessary to have a clear roadmap for implementing adaptation measures together a proper financing structure.

Abstract
AIMS Pseudomonas spp. have been widely studied for their plant growth-promoting effects. However, their capacity to promote lipid accumulation in oilseed crops is not well characterized. In this study, we evaluated the effect of Pseudomonas fluorescens LBUM677 on lipid accumulation in three oilseed crops: soybean (Glycine max), canola (Brassica napus) and corn gromwell (Buglossoides arvensis), a plant of high nutraceutical interest for its accumulation of the omega-3 stearidonic acid. METHODS AND RESULTS Pot experiments were conducted under controlled conditions where seeds were inoculated or not with LBUM677 and plants were harvested at 4, 8 and 12 weeks. A qPCR assay specifically targeting LBUM677 was used in parallel to correlate LBUM677 soil rhizosphere competency to growth promotion and seed lipid accumulation. Total oil seed content and fatty acid composition were analysed at seed maturity. Results showed that LBUM677 was able to establish itself in the rhizosphere of the three plant species at similar levels, but it differentially increased plant biomass, total oil content and lipid composition in a plant-specific manner. CONCLUSIONS Despite some species-specific differences observed in P. fluorescens LBUM677's effect on different crops, the strain appears to be a generalist plant growth-promoting rhizobacteria of oilseed crops. SIGNIFICANCE AND IMPACT OF THE STUDY LBUM677 shows great potential to be used as an inoculum to promote oil yield and fatty acid accumulation in oilseed crops.

Abstract
Chalcographic printer is the name given to a specific type of press which is used to transfer the printing of a metal-based engraved plate onto paper. The printing system consists of two rollers for pressing and carrying a metal plate onto which an engraved inked plate is placed. When the driving mechanism is operated, the pressure exerted by the rollers, also called contact pressure, allows the engraved image to be transferred into paper, thereby obtaining the final image. With the aim of ensuring the quality of the result, in terms of good and even transfer of ink, the contact pressure must be uniform. Nowadays, the strategies utilized to measure the pressure are implemented off-line, i.e., when the press machines are shut down for maintenance, which poses limitations. This paper proposes a novel sensor system aimed at monitoring the pressure exerted by the rollers on the engraved plate while chalcographic printer is operating, i.e., on-line. The purpose is two-fold: firstly, real-time monitoring reduces the number of breakdown repairs required, reduces machine downtime and reduces the number of low-quality engravings, which increases productivity and revenues; and secondly, the on-line monitoring and register of the process parameters allows the printing process to be reproducible even with changes in the environmental conditions or other factors such as the wear of the parts that constitute the mechanical system and a change in the dimensions of the printing materials. The proposed system consists of a strain gauge-based load cell and conditioning electronics to sense and treat the signals.

Abstract
Current microbial water quality monitoring is generally limited to culture-based measurements of fecal indicator bacteria (FIB). Given the many possible sources of fecal pollution within a watershed and extra-intestinal FIB reservoirs, it is important to determine source(s) of fecal pollution as a means to improve water quality and protect public health. The principal objective of this investigation was to characterize the microbial water quality of shellfish harvesting areas in the Gulf of Nicoya, Costa Rica during 2015. In order to achieve this objective, the specificity and sensitivity of 11 existing microbial source tracking (MST) PCR assays, associated with cows (BacCow), dogs (BacCan, DogBac), domestic wastewater (PMMoV), general avian (GFD), gulls (Gull2), horses (HorseBac, HoF), humans (HF183, HPyV), and pigs (PF), were evaluated using domestic wastewater and animal fecal samples collected from the region. The sensitivity of animal-associated assays ranged from 13 to 100%, while assay specificity ranged from 38 to 100%. The specificity of pepper mild mottle virus (PMMoV) and human polyomavirus (HPyV) was 100% for domestic wastewater, as compared to 94% specificity of the HF183 Bacteroidales marker. PMMoV was identified as a useful domestic wastewater-associated marker, with concentrations as high as 1.1 × 105 copies/ml and 100% sensitivity and specificity. Monthly surface water samples collected from four shellfish harvesting areas were analyzed using culture-based methods for Escherichia coli as well as molecular methods for FIB and a suite of MST markers, which were selected for their specificity in the region. While culturable E. coli results suggested possible fecal pollution during the monitoring period, the absence of human/domestic wastewater-associated markers and low FIB concentrations determined using molecular methods indicated sufficient microbial water quality for shellfish harvesting. This is the first study to our knowledge to test the performance of MST markers in Costa Rica as well as in Central America. Given the lack of wastewater treatment and the presence of secondary sources of FIB, this study highlights the importance of an MST toolbox approach to characterize water quality in tropical regions. Furthermore, it confirms and extends the geographic range of PMMoV as an effective tool for monitoring domestic wastewater pollution.

Abstract
Human biomonitoring (HBM) is an effective tool for assessing actual exposure to chemicals that takes into account all routes of intake. Although hair analysis is considered to be an optimal biomarker for assessing mercury exposure, the lack of harmonization as regards sampling and analytical procedures has often limited the comparison of data at national and international level. The European-funded projects COPHES and DEMOCOPHES developed and tested a harmonized European approach to Human Biomonitoring in response to the European Environment and Health Action Plan. Herein we describe the quality assurance program (QAP) for assessing mercury levels in hair samples from more than 1800 mother-child pairs recruited in 17 European countries. To ensure the comparability of the results, standard operating procedures (SOPs) for sampling and for mercury analysis were drafted and distributed to participating laboratories. Training sessions were organized for field workers and four external quality-assessment exercises (ICI/EQUAS), followed by the corresponding web conferences, were organized between March 2011 and February 2012. ICI/EQUAS used native hair samples at two mercury concentration ranges (0.20-0.71 and 0.80-1.63) per exercise. The results revealed relative standard deviations of 7.87-13.55% and 4.04-11.31% for the low and high mercury concentration ranges, respectively. A total of 16 out of 18 participating laboratories the QAP requirements and were allowed to analyze samples from the DEMOCOPHES pilot study. Web conferences after each ICI/EQUAS revealed this to be a new and effective tool for improving analytical performance and increasing capacity building. The procedure developed and tested in COPHES/DEMOCOPHES would be optimal for application on a global scale as regards implementation of the Minamata Convention on Mercury.

Abstract
An integrated data analysis system based on Bayesian inference has been developed for the TJ-II stellarator. It reconstructs the electron density profile at a single time point, using data from interferometry, reflectometry, Thomson scattering, and the Helium beam, while providing a detailed error analysis. In this work, we present a novel analysis of the ambiguity inherent in profile reconstruction from reflectometry and show how the integrated data analysis approach elegantly resolves it. Several examples of the application of the technique are provided, in both low-density discharges with and without electrode biasing, and in high-density discharges with an (L-H) confinement transition.

Abstract
The present work is aimed to evaluate the effects of a surface modification process on the biocompatibility of three vanadium-free titanium alloys with biomedical applications interest. Chemical composition of alloys investigated, in weight %, were Ti-7Nb-6Al, Ti-13Nb-13Zr, and Ti-15Zr-4Nb. An easy and economic method intended to improve the biocompatibiblity of these materials consists in a simple thermal treatment at high temperature, 750 degrees C, in air for different times. The significance of modification of the surface properties to the biological response was studied putting in contact both untreated and thermally treated alloys with human cells in culture, Human Umbilical Vein Endothelial Cells (HUVEC) and Human Peripheral Blood Mononuclear Cells (PBMC). The TNF-alpha release data indicate that thermal treatment improves the biological response of the alloys. The notable enhancement of the surface roughness upon oxidation could be related with the observed reduction of the TNF-alpha levels for treated alloys. A different behavior of the two cell lines may be observed, when adhesion molecules (ICAM-1 and VCAM-1 in HUVEC, ICAM-1, and LFA-1 in PBMC) were determined, PBMC being more sensitive than HUVEC to the contact with the samples. The data also distinguish surface composition and corrosion resistance as significant parameters for the biological response.

Abstract
In this study, we investigated the preclinical utility and antitumor efficacy of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) delivered by Ad-IU2, a prostate-specific replication-competent adenovirus (PSRCA), against androgen-independent prostate cancer. Through transcriptional control of adenoviral early genes E1a, E1b and E4, as well as TRAIL by two bidirectional prostate-specific enhancing sequences (PSES), expression of TRAIL as well adenoviral replication was limited to prostate-specific antigen (PSA) and prostate-specific membrane antigen (PSMA)-positive cells. Ad-IU2 induced 5-fold greater apoptosis selectively in PSA/PSMA-positive CWR22rv and C4-2 cells than an oncolytic adenoviral control. Furthermore, prolonged infection with Ad-IU2 reversed TRAIL resistance in LNCaP cells. Ad-IU2 exhibited superior killing efficiency in PSA/PSMA-positive prostate cancer cells at doses 5- to 8-fold lower than required by a PSRCA to produce a similar effect. This cytotoxic effect was not observed in non-prostatic cells, however. As an enhancement of its therapeutic efficacy, Ad-IU2 exerted a TRAIL-mediated bystander effect through direct cell-to-cell contact and soluble factors such as apoptotic bodies. In vivo, Ad-IU2 markedly suppressed the growth of subcutaneous androgen-independent CWR22rv xenografts compared to a PSRCA at six weeks post-treatment (3.1- vs. 17.1-fold growth of tumor). This study demonstrates the potential clinical utility of a PSRCA armed with an apoptosis-inducing ligand.

Abstract
Bone echinococcosis affects the spine and pelvis in 60% of cases. Bone lesions may be silent for between 10 and 20 years. The capsules progress aggressively through the medullary canal and replace the trabecular bone without forming cysts, as occurs in the organs, thus making anaplylaxis rare. The combination of chemotherapy and surgery facilitates anesthetic management and reduces the incidence of anaphylactic events and disease recurrence.

Abstract
This letter analyzes the performance of the neural network training method known as optimization layer by layer. We show, from theoretical considerations, that the amount of work required with OLL-Learning scales as the third power of the network size, compared with the square of the network size for commonly used conjugate gradient training algorithms. This theoretical estimate is confirmed through a practical example. Thus, although OLL is shown to function very well for small neural networks (less than about 500 weights per layer), it is slower than CG for large neural networks. Second, we show that OLL does not always improve on the accuracy that can be obtained with CG. It seems that the final accuracy that can be obtained depends strongly on the initial network weights.

Abstract
The most common complications after surgical extraction of the third mandibular molar are trismus, oedema or swelling, local pain, dysphagia and infection. The aim of this comparative, double-blind, randomized clinical trial was to evaluate the efficacy of two sustained release amoxicillin/clavulanate regimens in the reduction of infection after third molar extractive surgery. A total of 225 patients were randomized into three equal groups: placebo, prophylaxis with single pre-surgical dose of two tablets amoxicillin/clavulanate 1000/62.5 mg, and pre-emptive post-surgery therapy with two tablets amoxicillin/clavulanate 1000/62.5 mg BID for 5 days. A higher rate of infection (P=0.006) was found among patients receiving placebo (16%) than those receiving single-dose prophylaxis (5.3%) or 5-day pre-emptive therapy (2.7%). A relationship between both the duration (13.8% for long versus 7.4% for medium versus 1.6% for short) and difficulty (12.7% with ostectomy versus 3.5% without ostectomy; P=0.011) of surgical procedure and incidence of subsequent infection was also observed. Both prophylactic and therapeutic regimens versus placebo achieved greater reduction of pain after surgery on day 3 (P=0.001). Logistic regression analysis revealed a risk of infection of 24%, 9% and 4% for ostectomy with placebo, prophylaxis and pre-emptive treatment, respectively, whereas it was 7%, 2% and 1% if ostectomy was not performed. Pre-emptive therapy with the oral sustained release amoxicillin/clavulanate formulation reduced the rate of subsequent infection in patients undergoing ostectomy. Prophylaxis was beneficial in simpler procedures and may be indicated in cases where ostectomy is not performed.

Abstract
We report here the first nanoscale surface elasticity measurements on surface-modified titanium alloys using the force spectroscopy mode in scanning force microscopy. Samples of three vanadium-free titanium alloys, Ti-7Nb-6Al, Ti-13Nb-13Zr and Ti-15Zr-4Nb, were investigated. Surface modification of the three alloys was produced by thermal oxidation in air at 750 degrees C for different times, which resulted in the formation of protective oxide layers with different surface composition and morphology. The elastic properties of the surface layers were studied comparatively in the as-received Ti alloys and after the oxidation process using cantilevers with different stiffness to evaluate the influence of the indentation depth. In all cases, Young's modulus of the sample surfaces was found to be lower than 65GPa, and as low as 20GPa for some of the oxidized samples. Variations observed for the three oxidized Ti alloys can be related to the different chemical composition of the outer layers generated for the different oxidation times.

Abstract
INTRODUCTION Secondary prevention of venous thromboembolism (VTE) with vitamin K antagonists is often problematic in patients with cancer. We prospectively evaluated the effectiveness and safety of long-term subcutaneous dalteparin in a series of consecutive patients with symptomatic VTE and metastatic cancer. PATIENTS AND METHODS The study included 203 patients, aged 36-96 years. The initial treatment consisted of a 7-day course of subcutaneous dalteparin according to body weight. Then, patients received a fixed dose of 10 000 IU dalteparin once daily for at least 3 months. In patients developing transient thrombocytopenia the dose was reduced to 5000 IU daily while the platelet count remained <50,000; and to 2500 IU daily while it remained <10 000. Patients undergoing any surgical intervention during the study were put on 5000 IU daily during the first 4 days, switching thereafter to 10,000 IU. Patients undergoing any other invasive procedure (i.e. biopsies, punctures) received a 5000 IU dose the same day, instead of 10 000 IU. RESULTS Eleven patients (5.4%) developed major bleeding complications (6 fatal) during the 3-month study period, and 18 patients (8.9%) developed VTE recurrences (2 patients died). There were no higher complication rates in patients with either liver or brain metastases, nor during thrombocytopenia, surgery or invasive procedures. CONCLUSIONS Fixed dose 10,000 IU subcutaneous dalteparin once daily for 3 months was not associated with more complications in patients with liver or brain metastases. The dose adjustment for patients with thrombocytopenia, surgery or invasive procedures was safe too.

Abstract
We have evaluated the status of p53 expression in three squamous carcinoma cell lines that express high levels of PTHrP mRNA and protein and also cause hypercalcemia when grown in nude mice. All three of these lines possess a single p53 allele, each of which harbors a missense point mutation that gives rise to it mutant p53 protein with a denatured conformation. Using site-directed mutagenesis, we created a p53 expression construct bearing a missense mutation at codon 158, identical to that expressed by one of the cell lines. This construct and p53 constructs expressing representative denatured conformation mutants were then used to develop stably transfected lines, which expressed increased levels of PTHrP mRNA. Promoter-specific RNase protection indicated that this increase was due primarily to transcripts originating from the two TATA promoters, and not the GC-rich initiator element within the PTHrP gene. Cotransfection of mutant p53 expression vectors with a series of reporter constructs under the control of the human PTHrP promoter region showed that mutant p53 isoforms activated constructs containing multiple promoter elements and flanking sequences, but failed to activate constructs with individual promoters in isolation. These findings suggest that the activation of PTHrP gene expression by mutant p53 isoforms displaying a denatured conformation is dependent on interactions with sequences in the PTHrP gene regulatory region beyond the basal TATA promoters.

Abstract
Swine sewage could be source of nutrients and pollutants. This work estimates the environmental risk in nine samples from different farm treatment systems based on the evaluation of their effects in Daphnia magna acute test, and on the assessment of Cu, Zn and ammonia as main contributors. NH3 and Cu were responsible for LC50 results (1-5% of dilution). Organic compounds were quantified through several extraction methods (SPMDs, SPE and solvent extraction). A more exhaustive extraction was performed in an additional sample, which showed indole and phenol recoveries much higher than the previous ones. This method also includes PCBs (430 ppb) and fatty acids (approximately =150 ppm) quantification.

Abstract
By gently scraping off the surface of the lateral ventricles of adult bovine brains, we obtained sheets containing the ependymal layer and some attached sub-ependymal cells. Explants were cultured in serum-free medium or in two media enriched with 20% fetal calf serum or 20% adult bovine cerebrospinal fluid, and processed for different time intervals from 4 h to 60 days. For characterization of the ependymal cells we used antisera against S-100 protein, vimentin and glial fibrillary acidic protein (GFAP). For comparison, the ependyma of adult bovines and of fetuses from days 60 to 120 post coitum was studied in situ. The adult ependyma consisted of a ciliated, cuboid cell monolayer with short basal processes; it displayed S-100 immunoreactivity but only scarce deposits of vimentin and no GFAP. The fetal ependyma had the appearance of a pseudostratified epithelium with elongated nuclei and basal processes containing S-100 and vimentin from day 80 post coitum and GFAP from day 100 post coitum. In explants, no differences were seen between the three culture media; the ependyma became pseudostratified, developed basal processes and showed increasing amounts of S-100 and vimentin first, and subsequently also GFAP. These changes were concomitant with the onset of mitotic activity in the subependymal layer leading to the production of numerous cells. The morphological and immunocytochemical features of ependymal cells in cultured explants resembled those of fetal ependyma. Our results indicate that the culture of ependymal explants from adult bovine lateral ventricles is an useful model system for morphological and functional studies of the ependyma and for the analysis of cell proliferation in the subependymal layer.

Abstract
Cervicothoracic lesions are not uncommon in children. All cervicothoracic lesions except superficial lesions extend from the neck to the thorax through the thoracic inlet. Evaluation of this area involves multiple imaging modalities: plain radiography, ultrasonography, nuclear medicine, computed tomography, and magnetic resonance (MR) imaging. However, MR imaging is the method of choice for assessing the full extents of cervicothoracic lesions and their relationships to neurovascular structures. Cervicothoracic lesions can be classified as congenital lesions, inflammatory lesions, benign tumors, malignant tumors, and traumatic lesions. Lymphangioma is the most common cervicothoracic mass in children; other congenital lesions include hemangioma, thymic cyst, and vascular anomalies. Inflammatory adenopathy reactive to tuberculosis, mononucleosis, tularemia, cat-scratch fever, infection with human immunodeficiency virus, or other upper respiratory tract infections can manifest as cervicothoracic lesions; tuberculous abscesses and abscesses of other origins can also be seen. Lipoma, lipoblastoma, aggressive fibromatosis, and nerve sheath tumors (either isolated lesions or those associated with neurofibromatosis) can also occur as cervicothoracic masses. Malignant cervicothoracic tumors include lymphoma, thyroid carcinoma, neuroblastoma, and chest wall tumors (rhabdomyosarcoma, Ewing sarcoma, and neuroectodermal tumor). Traumatic cervicothoracic lesions include pneumomediastinum of traumatic origin, traumatic pharyngeal pseudodiverticulum, esophageal foreign-body granuloma, and cervicothoracic hematoma.

Abstract
Post-kala-azar dermal leishmaniasis (PKDL) is a rare clinical variant of cutaneous leishmaniasis. It is very common in the Indian subcontinent and less frequent in East Africa, but exceptional in the American and European continents. We have observed a case of PKDL in a renal transplant recipient. No systemic symptoms were present. The patient was treated with liposomal amphotericin B. We emphasize the unusual aspects of this case: the appearance of PKDL in Europe, its relationship with immunosuppression, the severe mucosal involvement and the excellent response to liposomal amphotericin B, a newly described treatment for the disease.

Abstract
BACKGROUND Trisetum paniceum is a grass plant which is characteristic of a Mediterranean continental climate and has been described as one of the major causes of type I allergy in the Madrid region. OBJECTIVES To identify and characterize the allergens of Trisetum paniceum pollen. METHODS Allergenic extracts were prepared by 24 h incubation of pollens in a buffered solution. Proteins were analysed by a new two-dimensional system in which agarose plates were used for isoelectric focusing. Two-dimensionally resolved proteins were electrically transferred to Immobilon membranes and the allergens immunochemically detected. Proteins from six grass pollens were bound to a membrane and incubated with a pool of serum from grass-pollen-sensitized patients. The bound IgE antibodies were then eluted and used to identify the proteins of Trisetum paniceum pollen that allergenically crossreact with allergens from other pollen grasses. RESULTS Relative to total protein content, Trisetum paniceum pollen had a high proportion of reactive proteins. On the basis of their molecular characteristics, allergens could be classified as group 1, 2, 4 and 5 components yet included an atypical proportion of basic components. All identified allergens were crossreactive with allergens from the remaining grass pollens studied. CONCLUSIONS Trisetum paniceum pollen contains a high proportion of allergens and these include a group of basic proteins which are not detected in other phylogenetically related pollens and could be of allergological interest.

Abstract
OBJECTIVE The existence of Platanus pollinosis is not generally accepted despite the production of very large quantities of airborne Platanus pollen in many cities of the United States and Europe. The aim of this study was to investigate if Platanus pollen really contributes to the symptoms of the patients with pollinosis in the Madrid area. METHODS We carried out systematic skin prick testing with Platanus pollen extract on 47 patients seen in our allergy center with spring-summer pollinosis symptoms. Each patient maintained symptom score diaries before, during, and after the Platanus pollination season. The average symptom scores were calculated and compared with the Platanus pollen counts. Measurements of specific IgE by ELISA and immunoblotting also were performed in each patient. RESULTS The Platanus skin tests were positive in 33 of the 39 patients first seen with seasonal symptoms during Platanus pollen season and only in three of the eight patients without symptoms during Platanus exposure (Fisher's exact test; p < 0.05). Twenty-two of the 33 Platanus-positive skin test patients also had a positive ELISA result. Furthermore, the average 24-hour rhinitis symptom scores of the 39 patients first seen with seasonal symptoms during March through April showed significant correlation with Platanus pollen counts (r(s) = 0.57, p < 0.05). The immunoblot results suggest that a 17 kd pollen protein could be a major allergen in patients with Platanus pollinosis. CONCLUSIONS Platanus pollen is an important cause of pollinosis in Madrid. A protein with a molecular weight of 17 kd appeared to be its major allergen.

Abstract
BACKGROUND Twelve cases of xanthogranulomatous cholecystitis (XGC) are presented, and their radiologic appearance is described. METHODS Four men and eight women, aged 31-82 years old, with XGC were reviewed. Abdominal ultrasound (US) was performed in all patients. Computed tomography (CT) was performed in five patients, barium enema examination in two, and percutaneously CT-guided fine-needle aspirative biopsy of the gallbladder in one. RESULTS Barium enema examination showed an indentation of the hepatic flexure. Cholelithiasis was present in all patients, and sludge was present in six. The gallbladder wall was thickened in all patients, irregular in nine, and could not be properly differentiated from surrounding liver parenchyma or from other adjacent structures in most patients. A curvilinear halo, hypoechoic on US and with low attenuation on CT, within the gallbladder wall was found in three patients and pericholecystic fluid in two others. On CT, the pericholecystic fat had streaky soft tissue densities in three cases. Percutaneously CT-guided fine-needle aspirative biopsy of the gallbladder was nondiagnostic. The diagnosis of gallbladder carcinoma was considered preoperatively in three patients. CONCLUSION Despite the characteristic histologic appearance of XCG, radiologic findings are nonspecific, varying from signs observed in other forms of cholecystitis to the appearance of a gallbladder neoplasm.

Abstract
OBJECTIVE A 15-year pollen count was performed in the atmosphere of Madrid, Spain, to determine the months in which the highest concentrations of allergenic pollens occur. METHODS Pollen counts were done with a Burkard spore trap (Burkard Manufacturing, Rickmansworth, Herst., U.K.). The results were subsequently compared with results of skin tests in patients with pollinosis born and living in and around Madrid. RESULTS The highest airborne presence (percent of total yearly pollen counts, mean of counts from 1979 to 1993) was for Quercus spp. (17%); followed by Platanus spp. (15%), Poaceae (15%), Cupressaceae (11%), Olea spp. (9%), Pinus spp. (7%), Populus spp. (4%), and Plantago spp. (4%). The most predominant pollens from January to April are tree pollens (Cupressaceae, Alnus, Fraxinus, Ulmus, Populus, Platanus, and Morus), although these are also abudant in May and June (Quercus, Olea, and Pinus spp.). The grass pollination period shows a double curve: the first peak occurs from February to April (8% of yearly grasses), and the second peak occurs from May to July (90% of yearly grasses). Among allergenically significant weeds, the most notable is Plantago; in contrast, Rumex, Urticaceae, Cheno-Amaranthaceae, and Artemisia spp. have very low concentrations (< or = 2% yearly total pollens). The most significant allergenic pollen is that of grasses, with a prevalence of positive prick test results of 94%, followed by Olea europaea (61%), Plantago lagopus (53%), Platanus hybrida (52%), and Cupressus arizonica (20%). CONCLUSION The population of Madrid is exposed to high concentrations of allergenic pollen from February to July, although the most intense period is from May to June. Grass pollens are the most important cause of pollinosis in this area.

Abstract
This work describes three patients suffering from bronchial asthma after being naturally exposed to airborne plane-tree pollen. The three patients gave immediate response in skin tests and dual response in bronchial provocations using Platanus hybrida extract. There was specific seric IgE activity against this/these antigen(s) with the CAP system. The three patients also showed significant correlation (P < 0.001) between their rhinitis and asthma symptom-scores registered on their diary cards and plane-tree pollen counts, collected using the Burkard spore trap. Among 187 patients living in Madrid and who came to our centre with a history of rhinitis and/or seasonal asthma, we found a prevalence of positive skin-prick tests to Platanus of 56%, only surpassed by gramineous pollen (Dactylis glomerata and/or Trisetum paniceum) 92% and Olea europaea 63%. The aerobiological sampling of the pollen content of the air in Madrid, carried out between 1 January 1979 and 31 December 1993 revealed an airborne presence (per cent of total yearly pollen count, mean of 1979-1993) of 14.9% for the Platanus, 14.8% for grasses, 9.8% for Olea and 3.6% for Plantago. The Platanus is one of the most frequently found pollens in the atmosphere over Madrid. At present, in this geographical area, a high percentage of patients with pollinosis are sensitive to this pollen. At least in some of these patients Platanus pollen is capable of inducing rhinitis and bronchial asthma.

Abstract
Inbreeding is known to lead to decreased survival and reproduction in captive populations of animals. It is also important to know whether inbreeding has deleterious effects in natural habitats. An estimate was made of the effects of inbreeding in white-footed mice, Peromyscus leucopus noveboracensis, derived from a wild population. This study demonstrates that inbreeding had a significant detrimental effect on the survivorship of mice reintroduced into a natural habitat. This effect was more severe than the effect observed in laboratory studies of the population.

Abstract
The aim of the present study was to ascertain whether sex differences exist in GH response to GHRH, and the influence that menstrual cycle have on this response. A GHRH test was performed on nine healthy men and ten women on days one and twelve of the menstrual cycle. Basal GH levels, (mean +/- SE) (7.98 +/- 3.09 ng/ml in women and 0.13 +/- 0.07 ng/ml in men, p less than 0.05) as well as maximal GH response (40.17 +/- 11.96 ng/ml in women and 9.63 +/- 2.32 ng/ml in males, p less than 0.01) were significantly higher in women than in men. In spite of a significant increase in estradiol levels during the menstrual cycle (75.88 +/- 2.48 pg/ml on day one and 198.40 +/- 28.65 pg/ml on day twelve, p less than 0.01) neither basal plasma GH levels, nor GH response to GHRH were significantly different. In conclusion, these results confirm that GH response to GHRH is higher in women than in men, and that this difference is not modified during the first phase of the menstrual cycle.

Abstract
We report a case of eosinophilic cystitis (EC) in an elderly patient who had previously undergone transurethral resection of a bladder tumor which is the reason why this diagnosis was not taken into consideration and was discovered by the pathologist in a fragment whose intraoperative diagnosis had been that of tumor recurrence. We describe the radiologic features of this disease entity and its similarity to other malignant conditions. Because of the foregoing, a differential diagnosis--both clinical as well as radiologic--must be made.
