Abstract
Avian pathogenic Escherichia coli (APEC) causes colibacillosis, the main bacterial disease in poultry leading to significant economic losses worldwide. Antibiotic treatments favor the emergence of multidrug-resistant bacteria, and preventive measures are insufficient to control the disease. There is increasing interest in using the potential of bacteriophages, not only for phage therapy but also for prevention and biocontrol. This study aimed to evaluate the efficacy of a phage cocktail administered in ovo to prevent avian colibacillosis in chicks. When 4 different phages (REC, ESCO3, ESCO47, and ESCO58), stable under avian physiological conditions, were combined and inoculated at 17 embryogenic days (ED), they were transmitted to the newly hatched chicks. In a second trial, the 4-phage cocktail was inoculated into the allantoic fluid at ED16 and after hatch 1-day-old chicks were challenged with the O2 APEC strain BEN4358 inoculated subcutaneously. Two phages (REC and ESCO3) were still detected in the ceca of surviving chicks at the end of the experiment (7-days postinfection). Chicks that received the phages in ovo did not develop colibacillosis lesions and showed a significant decrease in intestinal BEN4358 load (8.00 × 107 CFU/g) compared to the challenged chicks (4.52 × 108 CFU/g). The majority of the reisolated bacteria from the ceca of surviving chicks had developed full resistance to ESCO3 phage, and only 3 were resistant to REC phage. The partially or complete resistance of REC phage induced a considerable cost to bacterial virulence. Here, we showed that phages inoculated in ovo can partially prevent colibacillosis in 1-wk-old chicks. The reduction in the APEC load in the gut and the decreased virulence of some resistant isolates could also contribute to control the disease.

Abstract
The increase in antibiotic-resistant avian-pathogenic Escherichia coli (APEC), the causative agent of colibacillosis in poultry, warrants urgent research and the development of alternative therapies. This study describes the isolation and characterization of 19 genetically diverse, lytic coliphages, 8 of which were tested in combination for their efficacy in controlling in ovo APEC infections. Genome homology analysis revealed that the phages belong to nine different genera, one of them being a novel genus (Nouzillyvirus). One phage, REC, was derived from a recombination event between two Phapecoctavirus phages (ESCO5 and ESCO37) isolated in this study. Twenty-six of the 30 APEC strains tested were lysed by at least one phage. Phages exhibited varying infectious capacities, with narrow to broad host ranges. The broad host range of some phages could be partially explained by the presence of receptor-binding protein carrying a polysaccharidase domain. To demonstrate their therapeutic potential, a phage cocktail consisting of eight phages belonging to eight different genera was tested against BEN4358, an APEC O2 strain. In vitro, this phage cocktail fully inhibited the growth of BEN4358. In a chicken lethality embryo assay, the phage cocktail enabled 90% of phage-treated embryos to survive infection with BEN4358, compared with 0% of nontreated embryos, indicating that these novel phages are good candidates to successfully treat colibacillosis in poultry. IMPORTANCE Colibacillosis, the most common bacterial disease affecting poultry, is mainly treated by antibiotics. Due to the increased prevalence of multidrug-resistant avian-pathogenic Escherichia coli, there is an urgent need to assess the efficacy of alternatives to antibiotherapy, such as phage therapy. Here, we have isolated and characterized 19 coliphages that belong to nine phage genera. We showed that a combination of 8 of these phages was efficacious in vitro to control the growth of a clinical isolate of E. coli. Used in ovo, this phage combination allowed embryos to survive APEC infection. Thus, this phage combination represents a promising treatment for avian colibacillosis.

Abstract
Study question
How many frozen embryos are stored in Spain destined for donation to other couples, research, destruction, own use or abandoned?
Summary answer
In Spain, 5% of frozen embryos are destined for donation to other patients, 17% are fated for research, 17,7% for destruction and 12% are abandoned
What is known already
According to the latest data from the Spanish Fertility Society (SEF) registry, the total number of embryos stored in Spain in 2019, was 668.082. Clinics ask patients to specify their preferences for the embryo’s destinations such as: save the embryos for the future, donation to other patients, research, or discarding the embryos. Embryos were considered abandoned when a patient with frozen embryo/s stored failed to contact the clinic for > 2 years and the patient could not be located. However, it is not known how many embryos are assigned to each destination, neither in Spain nor in any other country
Study design, size, duration
Reflecting concern about the accumulation of frozen embryos in banks, SEF convened a focus group with key figures in ethics, law, and reproductive medicine to identify possible solutions. The first step was to carry out a questionnaire to all the reproduction centres in Spain to know the number of frozen embryos stored and their destinations. A total of 242 IVF units were contacted through SEF newsletter and participants answered between April and July 2021
Participants/materials, setting, methods
Public and private IVF clinics which had cryopreserved embryos were sent questionnaires with requests regarding the number of frozen embryos in each destination: keeping for patients, donated to other patients who met donation criteria (same as for gamete donors) and who did not meet criteria, research to a specific project and without a project, destined for destruction that met the criteria established by law, and that did not meet criteria, and number of embryos abandoned.
Main results and the role of chance
A total of 71 filled-in questionnaires from 242 IVF clinics were obtained. The response rate to the questionnaire was 29%. Of the respondents, a total of 376.445 stored embryos were reported. 46% of the total cryopreserved embryos were kept for later use by patients. 3.7% were donated to other couples but did not meet the criteria for donation: obtained from women over 35 years, or lack of any required test. 1.4% of the embryos were donated fulfilling the criteria for donation to other patients. 17% of the embryos were donated for research, but less than 1% had an assigned project. 17.7% of the frozen embryos were destined for termination of their conservation, and 1.4% of them did not meet the criteria established by law. A total of 46.046 embryos could be considered abandoned since the patients could not be contacted after more than two years of storage. This represents 12.2% of embryos without a defined destination.
Limitations, reasons for caution
The main limitation of this study is the low response rate, since out of 242 centres, which obligatory sent their data to the National Registry in 2019, only 71 centres answered. This could be due to the lack of data from some reproduction units
Wider implications of the findings
It is not known precisely how many frozen embryos have been abandoned in Spain, or what are their other destinations. Clinics are not required by authorities to report these number but to have concrete data on the frozen embryos is crucial to solve the problem of embryo accumulation in banks.

Abstract
INTRODUCTION Acute pulmonary histoplasmosis (APH) is rare in an immunocompetent patient. We report a case of APH diagnosed by culture of broncho-alveolar lavage (BAL) in a patient presenting a pseudo-tumoral form with nodules progressing to cavitation. OBSERVATION A 41 year-old male smoker was hospitalized with a persistent fever, dry cough and dyspnoea on exertion. The first CT scan showed a reticulo-nodular interstitial infiltrate with lymphadenopathy that progressed rapidly to multiple pulmonary nodules with central cavitation. Bronchial endoscopy, with BAL culture, provided the diagnosis of Histoplasma capsulatum, variety capsulatum. The infection may have occurred during work in a hangar in Guadeloupe that was scattered with bats' guano. After two months of treatment by itraconazole, the patient's condition improved clinically and radiologically with reduction of the nodules and their cavitation. CONCLUSION This case presents an immunocompetent patient with pulmonary histoplasmosis and multiple, radiologically atypical, nodules. The diagnosis was established by BAL culture.

Abstract
Abstract
Nitrite and nitrate are used as additives in the food industry to provide color and taste and to control undesirable gas and flavor production by anaerobic bacteria by virtue of their antimicrobial properties. The analytical method that has been widely used to determine nitrite and nitrate involves the use of toxic cadmium. In response to a request from the Nordic Committee on Food Analysis, a study was performed to obtain an alternative chromatographic method to determine residual nitrite and nitrate in meat products. The study was done in 3 stages: (1) comparative evaluation of the performance of 3 liquid chromatographic methods, (2) internal validation of the selected ion chromatographic method, and (3) a collaborative study in which 17 laboratories from European countries participated. Furthermore, the applicability of the method to matrixes other than meat and meat products was demonstrated. The results of the collaborative study show that the European Prestandard prENV 12014-4 is well suited for the determination of nitrite and nitrate in different foods (e.g., meat products, vegetables, baby food, and cheese). The limits of detection for nitrite and nitrate ions are 1 and 10 mg/kg, respectively. Recoveries of residual nitrite/nitrate ranged from 96 to 108%. Repeatability and reproducibility were satisfactory.

Abstract
Abstract
Background
The aim of this study is to assess the economic burden of diabetes in France based on a top-down allocation of health care expenditure, and to analyze structure and trends of expenditure between 2012 and 2017.
Methods
Using information about 57 millions of individuals from the general scheme insurance database (87% of the French population), we applied algorithms based on ICD-10 diagnoses, long-term diseases, and specific treatments. All reimbursed expenditure (drugs, medical visit and other ambulatory care, hospitalization, disability/sickness benefits) were extracted for each individual. A top-down method was used to allocate expenditure to diabetes. To analyze trends, we applied the same methodology from 2012 through 2017.
Results
In 2016 (results for 2017 will be available for the conference), among the 137 billion euros reimbursed, 6.8 billion (5%) were attributed to diabetes and 3.2 million people were concerned (5.5% of the population). Drugs represented the main expenditure item (31% of the average annual expenditure per patient related to diabetes), followed by nursing (18%) and medical devices (17.5%). From 2012 to 2016, the number of people with diabetes increased by 11.4% (+322 700) with an increase by 2.7%/year, the expenditure attributed to diabetes increased by 2.3%/year. The average expenditure per patient in 2016 was about €2150, slightly decreasing from 2012, mainly due to price controls on antidiabetics drugs which permits to limit expenditure growth.
Conclusions
Our study shows the high economic burden of diabetes in France with a detailed analysis of expenditures and their main drivers. With the arrival of innovation and predicted increase of the number of patients partly related to ageing process, control of expenditure must be a priority. The developed tool will help decision makers to monitor the burden of diabetes but also to provide stakeholders with a better understanding of trends and regulating actions.
Key messages
Diabetes represents a high proportion of healthcare expenditure in France. With the arrival of innovation and predicted increase of the number of patients partly related to ageing process, control of expenditure must be a priority.

Abstract
Abstract
Background
The purpose of this study was to assess the economic burden of cardiovascular diseases (CVDs) in France by analysing the structure and the growth of expenditure attributed to these diseases between 2012 and 2017.
Methods
For each year, 11 CVDs were identified from SNDS data using algorithms based on long-term disease registry and hospitalization diagnoses, applied to the population of national health insurance general scheme beneficiaries. The individuals’ expenditure (26 different items) reimbursed for hospitalisations, ambulatory care and cash payments were included. A top-down method was used to attribute expenditure to each considered groups of diseases based on the average expenditure by disease calculated for individuals with only one disease. To analyse trends, we applied the same methodology from 2012 to 2017.
Results
In 2017, of the €140.1 billion reimbursed, €14.0 billion (10.0%) were attributed to the care of 4.0 million people with a CVD (7.0% of the population). Short-stay hospitalisations accounted for 33% of this total expenditure. This proportion was higher for acute CVD (coronary syndrome: 64%, stroke: 56%, heart failure: 65%, pulmonary embolism: 69%) but also for valvular heart disease (50.0%). Medications represented almost 13% of the expenditure attributed to all CVDs, and up to 25% for chronic coronary heart disease. Disability pension essentially concerned sequelae of stroke (12% of the expenditure attributed to this disease). Between 2012 and 2017, the total expenditure attributed to CVDs increased by 3.3% per year, mainly due to the annual mean increase of the number of patients over the period (+3.1%).
Conclusions
These results demonstrate the high economic burden of CVDs in France with a detailed analysis of expenditures and their main drivers. The developed tool will help decision makers to monitor the burden of these diseases but also to provide stake holders with a better understanding of trends and regulating actions.
Key messages
Economic burden of CVD in France is high: 10% of healthcare expenditure. Implementation of public health policy to prevent CVD and control risk factors must be a priority.

Abstract
Background
The aim of this study is to assess the economic burden of active cancer in France and to analyze structure and trends of expenditure between 2012 and 2017.
Methods
Using information about 57 millions of individuals from the general scheme insurance database (86% of the French population) and applying 5 specifically developed medical algorithms (for lung, colon, breast, prostate and other cancers), we identified all people with active cancer. All reimbursed expenditure (hospitalization, ambulatory care, disability/sickness benefits) were extracted for each individual. To analyze trends, we applied the same methodology from 2012 through 2017.
Results
In 2016 (results for 2017 will be available for the conference), among the 137 billion euros reimbursed by the general assurance scheme, 13 billion (10%) were related to active cancer and 1.2 million people were concerned (2% of the population). About 2.3 billion euros (2%) were related to breast cancer (189,000 people), 1.4 billion euros (1%) for colon cancer (123,000 people), 1.4 billion euros (1%) for lung cancer (77,000 people) and 1 billion (0.8%) for prostate cancer (167,000 people). Hospitalizations represented the main expenditure for colon (71%), lung (61%) and breast cancer (56%). Concerning prostate cancer, hospitalizations stood for 36% while ambulatory care represented 62%. From 2012 to 2016, the expenditure related to active cancer increase by 4.4%/year due to both an increase in patients and in the average annual cost per patient (both +2.2% per year). Focusing on breast cancer, average expenditure increased by 3.2% per year from 10,700€ per year per patient to 12,200€ per year per patient.
Conclusions
Our study demonstrates the high economic burden of active cancer in France with a detailed analysis of expenditures. The developed tool will help to monitor the burden of these diseases and to implement public health policies.
Key messages
Active cancers account for a significant proportion of healthcare expenditure in France. Knowing this weight allows designing and implementing public policies adapted to the situation.

Abstract
Background Kodamaea ohmeri is a yeast is frequently mistaken for Candida, which belongs to the same family. This micro-organism has been reported to cause life-threatening infections in humans. Case presentation A 81-year-old woman developed a severe fungemic pulmonary infection due to Kodamaea ohmeri that was identified from bronchoalveolar fluid and blood cultures, which is unusual in immunocompetent patients. Because K. ohmeri was first wrongly identified as Candida albicans, the patient inadequately received caspofungin, which was clinically ineffective, especially as the strain was resistant to echinocandins. Clinical cure was obtained after treatment was switched to voriconazole. Conclusions An increasing number of serious infections due to K. ohmeri has been reported in the literature, but the correct identification of this micro-organism remains difficult.

Abstract
Cystinuria is a heterogeneous, rare but important cause of inherited kidney stone disease due to mutations in 2 genes: SLC3A1 and SLC7A9. Antenatal hyperechoic colon (HEC) has been reported in some patients as a non-pathological consequence of the intestinal transport defect. We report 83 patients affected by cystinuria: 44 presented prenatally with a HEC (HEC group) and 39 with a classical postnatal form (CC group). SLC3A1 and SLC7A9 were sequenced. All patients were fully genotyped, and the relationship between the genotype and clinical features was analyzed. We identified mutations in SLC3A1 in 80% of the HEC group and in only 49% of the CC group. The SLC3A1 p.Thr216Met mutation was found in 21% of the alleles in the HEC group but was never found in the CC group. Most of the mutations found in the HEC group were considered severe mutations in contrast with the CC group. Twenty-five novel mutations were reported. This study shows a relationship between genotype and the clinical form of cystinuria, suggesting that only the patients with the most severe mutations presented with an HEC. These results emphasized the need for prenatal cystinuria screening using classical third-trimester ultrasound scan and the early management of suspected newborns.

Abstract
We study the time evolution of the compaction of a noncohesive or cohesive granular material submitted to shaking through experiments and a stochastic model. Beyond well-known empirical expressions, we show that the characteristic time scales depend on the number of objects in the assembly. For a noncohesive granular material, the compaction time scale is governed by the number of individual grains in the system. In the case of a cohesive granular material, a two-scale model (individual particles and clusters) allows one to mimic the time evolution of the compaction of an actual cohesive powder driven by horizontal vibrations. In this case, the two time scales are associated with the numbers of clusters and grains, respectively.

Abstract
Abstract
Background: In 2014, UNICANCER, composed of 18 French Comprehensive Cancer Centers, launched the Epidemiological Strategy and Medical Economics (ESME) program to investigate real-world data in oncology. Real-world data give the opportunity to assess the activity of specific products outside the framework of clinical trials. Oral vinorelbine (OV) is one of the therapeutic options available for metastatic breast cancer (mBC). Few data are available regarding its real clinical efficiency in current practice. We aimed at evaluating such activity within the ESME population.
Methods: The ESME-mBC database was built from information systems, treatment databases and patients' electronic files, with homogenous on-site collected information and high-level quality-control (Delaloge et al, Ann. Oncol 2016 (in press)). All patients having started a systemic treatment for mBC in a cancer center participating in the ESME program between 01-Jan-2008 and 31-Dec-2013 have been selected into the database.
For the purpose of the current analyses, data cut-off was July, 2015 and all patients who received OV at any time during the course of their disease were selected and analyzed. Primary end point was progression-free survival (PFS) from initiation of OV. Secondary end points were descriptive and prognostic analyses, and overall survival (OS).
Results: Among 13.853 patients recorded in the ESME-mBC database, 1402 received OV as a monotherapy or in combination (809 and 593 patients / 57.7% and 42.3% respectively). Most frequent combinations were with capecitabine (368 patients) and anti-HER2 therapy (165 patients). De-novo mBC was observed in 282 patients (20.1%) and 569 patients (40.6%) had only non-visceral metastases. At metastatic diagnosis, 221 patients (16.9%) had HER2-positive and 298 patients (22.9%) triple-negative tumors respectively. At OV initiation, median age was 59.0 [IC95%: 50-67] years. Endocrine therapy was given prior OV in 769 patients (54.9%). For PFS analysis, 1345 patients were evaluable. The following table summarizes PFS results according to the treatment patterns and the OV-line.

Following diagnosis of mBC, median OS was 38.2 months [IC95%: 36.1-40.0] in the cohort of patients who received OV at any time.
Conclusions:This study allows large scale assessment of real life benefit of OV over subsequent lines and shows that OV yields clinical benefit even in heavily pre-treated mBC patients.

Abstract
BACKGROUND Neurocysticercosis is endemic in most countries of Central and South America but has rarely been described in the French West Indies. We aimed to better understand the clinical and radiological presentation of our cases. CASE PRESENTATION We report three cases of neurocysticercosis in patients living in Guadeloupe, with different clinical and radiological presentations. CONCLUSION Given the eventuality of autochtonous transmission, the diagnosis should be considered in all patients living in Guadeloupe presenting with seizures.

Abstract
The aim of this study was to investigate levels of expression of two major genes, the odorant binding protein Gp-9 (general protein-9) and foraging, that have been shown to be associated with behavioural polymorphisms in ants. We analysed workers and young nonreproductive queens collected from nests of the monogyne (single reproductive queen per nest) and polygyne (multiple reproductive queens) social forms of Solenopsis invicta. In workers but not young queens, the level of foraging expression was significantly associated with social form and the task performed (ie localization in the nest or foraging area). The level of expression of Gp-9 was also associated with social form and worker localization. In addition there was a higher level of expression of the Gp-9(b) allele compared with the Gp-9(B) allele in the heterozygote workers and the young nonreproductive queens. Finally, in the polygyne colonies the level of expression of foraging was not significantly associated with the Gp-9 genotype for either workers or young nonreproductive queens, suggesting that both genes have independent non-epistatic effects on behaviour in S. invicta.

Abstract
The objective of this study was to reverse the osmotic stress of sperm in urine contaminated bear ejaculates that were obtained by electroejaculation using pre-freezing washing or density gradient centrifugation isolation. In Experiment 1, ejaculates were divided into six aliquots, five were diluted in each washing extender: 200, 300, 400, 500 and 700 mOsm/kg (prepared from a Tes-Tris-Fructose base, adding water or fructose as corresponds), at a 1:2 ratio (raw semen: washing solution, v/v); and the other aliquot was handled without washing (Control group). Samples were centrifuged at 600 × g for 6 min prior to freezing. In Experiment 2, ejaculates were divided into two aliquots: one was diluted 1:1 with TCG (Tris-Citric acid-Glucose) and centrifuged at 600 × g for 6 min (Centrifugation Control; C-Control); the other was treated with PureSperm density gradient column. After treatments, samples were cryopreserved. Sperm motility, viability (SYBR-14/propidium iodide (PI)) and acrosomal status (peanut agglutinin-fluorescein isothiocyanate (PNA-FITC)/PI) were analyzed before and after freezing. Ejaculates with an initial osmolality of less than 120 mOsm/kg treated with pre-freezing washing, and the Control sample had greater pre-freezing sperm motility than the raw ejaculate, but sperm viability was not different among these groups. The samples washed with 700 mOsm/kg solutions had the least pre-freezing viability. In the post-thawing evaluation, pre-freezing washing treatments did not provide any improvement in comparison with the Control sample, and treatment with 700 mOsm/kg extender had deleterious effects in all urospermic samples. PureSperm density gradient centrifugation applied to urospermic raw semen was suitable for improving sperm motility and viability of pre-freezing samples and the selected spermatozoa had greater freezing capacity.

Abstract
Volatile organic compounds (VOCs) and particles emitted by incense sticks and candles combustion in an experimental room have been monitored on-line and continuously with a high time resolution using a state-of-the-art high sensitivity-proton transfer reaction-mass spectrometer (HS-PTR-MS) and a condensation particle counter (CPC), respectively. The VOC concentration-time profiles, i.e., an increase up to a maximum concentration immediately after the burning period followed by a decrease which returns to the initial concentration levels, were strongly influenced by the ventilation and surface interactions. The obtained kinetic data set allows establishing a qualitative correlation between the elimination rate constants of VOCs and their physicochemical properties such as vapor pressure and molecular weight. The emission of particles increased dramatically during the combustion, up to 9.1(±0.2) × 10(4) and 22.0(±0.2) × 10(4) part cm(-3) for incenses and candles, respectively. The performed kinetic measurements highlight the temporal evolution of the exposure level and reveal the importance of ventilation and deposition to remove the particles in a few hours in indoor environments.

Abstract
BACKGROUND To evaluate the long-term efficacy of multilayer amniotic membrane transplantation for reconstruction of epithelium and stroma in non-traumatic corneal perforations (less than 2 mm) or deep ulcers with descemetocele. DESIGN Retrospective, non-comparative, interventional case series. PATIENTS AND METHODS Eleven consecutive patients with non-traumatic corneal perforations or deep corneal ulcers with descemetocele refractory to conventional treatments: herpetic or zoster keratitis (n = 4), Sjögren's syndrome (n = 2), rosacea (n = 1), hydrops (n = 1), mucous membrane pemphigoid (n = 1), bacterial keratitis (n = 1) and perforation after protontherapy for melanoma (n = 1). Intervention was: multilayer amniotic membrane transplantation with cryopreserved amniotic membrane. Complication rate and clinical outcome were evaluated in this long-term follow-up. RESULTS Mean follow-up was 32 months (12 to 60). Integration of the multilayer amniotic membrane was obtained in 10 cases after one year. Corneal epithelium healed above the membrane in 10 cases within 3 weeks and remained stable after 32 months in 9 cases. Thickness of the stroma was increased and remained stable during the follow-up in 9 cases. In one case herpetic keratitis recurred with a corneal perforation. The clearing of the amniotic membrane was gradually obtained over a period of 11 months. Complications occurred in 15% of the eyes during the long-term follow-up. CONCLUSION Multilayer amniotic membrane transplantation is a safe and efficient technique for a long restoration of the corneal integrity after non-traumatic corneal perforations or deep corneal ulcers with descemetocele. Long-term prognosis of these eyes depends of the gravity of the initial disease.

Abstract
Centrifugation is a crucial procedure in sperm cryopreservation protocols of brown bear (Ursus arctos), because the semen must be processed to increase sperm concentration and/or clean urine-contaminated samples. The efficacy of three media for centrifugation (Maxifreeze [IMV technologies, L'Aigle, France], Cushion Fluid Equine (Minitübe, Tiefenbach, Germany), and PureSperm [Nidacon, Gothenburg, Sweden]) on the quality of bear spermatozoa was evaluated. In experiment one, two cushioned media used for protecting against mechanical stress during centrifugation were analyzed. In experiment two, a density gradient based on PureSperm was assessed in relation to the maximum retrieval and the quality of fresh spermatozoa, and the freezability of the spermatozoa selected in this density gradient was studied in experiment three. Finally, the selection of frozen-thawed sperm using PureSperm was analyzed in experiment four. Our results indicate that the use of dense isotonic cushion solutions (Maxifreeze, Cushion Fluid Equine) in centrifugation did not improve the quality of recovered spermatozoa compared with standard centrifugation. However, a density gradient prepared with PureSperm improved the quality of spermatozoa in fresh semen and frozen-thawed semen, but the spermatozoa selected from the fresh sample with this density gradient did not show a better resistance to freezing with this density gradient in comparison with the control sample.

Abstract
The trace metal (TM: Cd, Cu, Ni, Pb and Zn) budget (stocks and annual fluxes) was evaluated in a forest stand (silver fir, Abies alba Miller) in north-eastern France. Trace metal concentrations were measured in different tree compartments in order to assess TM partitioning and dynamics in the trees. Inputs included bulk deposition, estimated dry deposition and weathering. Outputs were leaching and biomass exportation. Atmospheric deposition was the main input flux. The estimated dry deposition accounted for about 40% of the total trace metal deposition. The relative importance of leaching (estimated by a lumped parameter water balance model, BILJOU) and net biomass uptake (harvesting) for ecosystem exportation depended on the element. Trace metal distribution between tree compartments (stem wood and bark, branches and needles) indicated that Pb was mainly stored in the stem, whereas Zn and Ni, and to a lesser extent Cd and Cu, were translocated to aerial parts of the trees and cycled in the ecosystem. For Zn and Ni, leaching was the main output flux (>95% of the total output) and the plot budget (input-output) was negative, whereas for Pb the biomass net exportation represented 60% of the outputs and the budget was balanced. Cadmium and Cu had intermediate behaviours, with 18% and 30% of the total output relative to biomass exportation, respectively, and the budgets were negative. The net uptake by biomass was particularly important for Pb budgets, less so for Cd and Cu and not very important for Zn and Ni in such forest stands.

Abstract
The potential health effects of fine and ultrafine particles are of increasing concern. A better understanding of particle characteristics and dispersion behavior is needed. This study aims at characterizing spatial and temporal variations in fine and ultrafine particle dispersion after emission from a model source in an experimental house. Particles emitted by an incense stick burning for 15 min were characterized. Number concentration, specific surface area and mass were measured. Partial chemical analysis of particles was also realized. Near the burning incense stick, the maximum concentration was 25,500 particles/cm(3); the indoor PM(2.5) concentration reached 197 microg/m(3), and the specific surface area concentration was 180 microm(2)/cm(3). The estimated incense smoke density was 1.1 g/cm(3). Time of Flight Aerosol Mass Spectrometer measurements indicated that the organic fraction was predominant in the aerosol mass detected, and other minor components identified were K(+), NO(3)(-), and Cl(-). The combustion of an incense stick in the living room was associated with significant modifications of the concentrations of particles measured in the different rooms of the house. This demonstration of pollution by particle dispersion by a model source of moderate intensity may have significant implications in terms of assessment of indoor exposure to such particles. Practical Implications The particles emitted in a domestic environment by a source of moderate intensity such as burning incense disperse throughout the house, even in rooms with closed doors and in rooms as far away as the next floor. This dispersion has significant implications in terms of evaluating human indoor exposure to fine and ultrafine particles.

Abstract
Maintenance of population viability, especially endangered species, requires preservation of as much genetic variability as possible, therefore genetic resource banks are very important. For male gametes, preservation of all available sources (ejaculates and epididymal) are useful. Information regarding sperm characteristics of most wild ruminant species is limited compared to that from domestic species. The objective of this work was to characterize the freezability of electroejaculated and epididymal spermatozoa from a wildebeest (5 year old; housed in Cabárceno Nature Park, Cantabria, Spain) that was castrated because of behavioral problems. After general anesthesia (ethorfine + xilazine, 1.8 mL + 0.5 mg kg–1) with dart, semen was collected by electroejaculation (3 V and 75 mA). Sperm concentration was 250 × 106 mL–1 (total spermatozoa: 1128.6 × 106). After castration, epididymides were disected and spermatozoa were collected by making several incisions in the caudal epididymis. Concentration was 12 441 × 106 spermatozoa mL–1 (total spermatozoa: 24 882 × 106). Samples were diluted to 200 × 106 spermatozoa mL–1 (TesT-Fructose-Egg yolk-Glycerol-Antibiotics) and chilled to 5°C during 2 h. Diluted semen was packaged in 0.25-mL straws and frozen from 5°C to –100°C (–20°C min–1) in a programmable cell freezer (Kryo 10, Planer). Straws were plunged into liquid nitrogen until analysis and thawed in a water bath (65°C, 6 s). Fresh, pre-freezing and post-thawed samples were analysed for motility (total motility TM, %; progressive motility PM, %; path velocity VAP, μm s–1; track speed VCL, μm s–1; progressive velocity VSL, μm s–1) using a CASA (ISAS, Proiser, Valencia, Spain). Viability (VIAB %) (SYBR-14 and propidium iodide) and mitochondrial membrane potential (MIT %) (JC1) were assessed by flow cytometry. Post-thawing results for electroejaculated v. epididymal samples were, respectively: TM: 87.0 v. 64.6%; PM: 68.7 v. 33.4%; VAP: 95.9 v. 49.8 μm s–1; VCL: 108.3 v. 71.6 μm s–1; VSL: 86.7 v. 40.2 μm s–1; VIAB: 57.0 v. 73.9%; MIT: 59.5 v. 77.5%. Motility parameters were higher for the electroejaculated sample; however, viability was higher for the epididymal sample. Recovery rates (post-thawed value/pre-freezing value × 100) for electroejaculated v. epididymal samples were: TM: 97.2 v. 93.4%; PM: 113.3 v. 103.2%; VAP: 88.9 v. 122.0 μm s–1; VCL: 87.5 v. 126.0 μm s–1; VSL: 93.4 v. 125.3 μm s–1; VIAB: 75.0 v. 97.7%; MIT: 69.2 v. 95.9%). These rates suggest a good freezability of electroejaculated and epididymal spermatozoa in blue wildebeest.

Abstract
Hyperglycosylated human chorionic gonadotropin (H-hCG) is secreted by the placenta in early pregnancy. Decreased H-hCG levels have been associated with abortion in spontaneous pregnancy. We retrospectively measured H-hCG and dimeric hCG in the sera of 87 in vitro fertilization patients obtained in the 3 weeks following embryo transfer and set the results in relation to pregnancy outcome. H-hCG and dimeric hCG were correlated (r(2) = 0.89), and were significantly decreased in biochemical pregnancy (2 microg/l and 18 IU/l, respectively) compared to early pregnancy loss (22 microg/l and 331 IU/l) and ongoing pregnancy (32 microg/l and 353 IU/l). Only H-hCG tended to discriminate between these last two groups.

Abstract
BACKGROUND Chromomycosis is a widespread subcutaneous fungal infection seen essentially in tropical and subtropical regions and transmitted via skin injury caused by the prickles of plants or infected wood splinters. It is prevalent throughout the West Indies including Guadeloupe, where its incidence is not well known. PATIENTS AND METHODS This retrospective and descriptive study concerns five histologically established cases of chromomycosis in Guadeloupe between 1995 and 2005. The five patients were diagnosed and treated at Pointe-à-Pitre University Teaching Hospital. RESULTS The study concerned four male patients and one female patient with an average age of 78 years; four were from the Basse-Terre district and one was from the Grande-Terre district. The most frequent clinical aspect was nodular or verrucous. The most common initial topography was the upper limbs. Fonsecaea pedrosoi was the only species identified. Diagnosis was confirmed by histopathology, which in all cases revealed sclerotic cells. Three patients underwent surgical treatment and two received medical treatment; only two patients were cured by 2005. DISCUSSION Our study confirms the presence of a source of chromomycosis in Guadeloupe, where Fonsecaea pedrosoi is clearly the best adapted species. It also highlights the difficulties of therapeutic care in tropical areas.

Abstract
Application of new sperm assessment techniques would improve our capability to determine the effects of cryopreservation on sperm function. This becomes relevant when germplasm banks are established for endangered species, as in the case of the brown bear in Spain. Different triple stain techniques have been used in conjunction with flow cytometry to assess various sperm attributes including viability and acrosome status. However, fluorochromes with similar emission spectra may interfere with data resolution, making acquisition and interpretation of data difficult. The double stain combination of SYBR-14 and PI (propidium iodide; max λ 617) has been widely used to differentiate live from dead spermatozoa (spz), and, more recently, merocyanine 540 (MC; max λ 555) has been used to detect a sperm membrane lipid disorder associated with sperm capacitation. In the present study, we analyzed the suitability of combining SYBR-14/PI with MC for simultaneous determination of the viability and capacitation status of frozen–thawed spermatozoa of brown bears (n = 10; semi-free ranging; Cabarceno Park, Cantabria, Spain) obtained by electroejaculation under general anesthesia (7 mg kg-1 tiletamine + zolazepan and 2 mg kg-1 ketamine). Semen was diluted (Tes-Tris-fructose, 8% glycerol, 20% egg yolk, EDTA, and Equex paste), loaded in 0.25-mL straws, and frozen in a biofreezer at 20�C min-1 to -100�C. After storage in liquid nitrogen, samples were thawed at 65�C for 6 s, divided into 2 aliquots (1–2 million spz mL-1), extended with 300 �L PBS, and stained with SYBR14 (1.2 �L) and PI (3 �L; LIVE/DEAD� Sperm Viability Kit; Molecular Probes, Inc., Eugene, OR, USA). To evaluate the possible interaction of MC on sperm viability, half of the aliquots were counterstained with 1.5 �L of MC (diluted with 2.7 �M of DMSO); the other half were not counterstained (control). All tubes were incubated at 37�C for 30 min, and assessed by flow cytometry (FACSCalibur; BD Biosciences, San Jose, CA, USA). Data were analyzed with Bland-Altman. Results indicated that MC staining was mainly confined to dead spermatozoa (22.2 � 7.7%), whereas a lower percentage of live spermatozoa (5.7 � 1.6%; P < 0.05) were also stained with MC. Possibly, the staining of dead spermatozoa with MC was due to capacitation changes induced by cryopreservation. The percentage of live spermatozoa was not different between samples counterstained with MC (68.9 � 9.2) and non-MC-stained control samples (68.6 � 8.8). Thus, we consider that MC does not influence SYBR14/PI discrimination of viable spermatozoa, and that the 3 stains can be used simultaneously. However, more studies are necessary to determine whether MC can be used to distinguish the capacitation status of brown bear thawed spermatozoa.
