Abstract
Ovarian cancer is the leading cause of death from gynecologic cancer worldwide. High-grade serous carcinoma (HGSC) is the most common and deadliest subtype of ovarian cancer. While the origin of ovarian tumors is still debated, it has been suggested that HGSC originates from cells in the fallopian tube epithelium (FTE), specifically the epithelial cells in the region of the tubal-peritoneal junction. Three main lesions, p53 signatures, STILs, and STICs, have been defined based on the immunohistochemistry (IHC) pattern of p53 and Ki67 markers and the architectural alterations of the cells, using the Sectioning and Extensively Examining the Fimbriated End Protocol. In this study, we performed an in-depth proteomic analysis of these pre-neoplastic epithelial lesions guided by mass spectrometry imaging and IHC. We evaluated specific markers related to each preneoplastic lesion. The study identified specific lesion markers, such as CAVIN1, Emilin2, and FBLN5. We also used SpiderMass technology to perform a lipidomic analysis and identified the specific presence of specific lipids signature including dietary Fatty acids precursors in lesions. Our study provides new insights into the molecular mechanisms underlying the progression of ovarian cancer and confirms the fimbria origin of HGSC.

Abstract
Integrating tumor heterogeneity in the drug discovery process is a key challenge to tackle breast cancer resistance. Identifying protein targets for functionally distinct tumor clones is particularly important to tailor therapy to the heterogeneous tumor subpopulations and achieve clonal theranostics. For this purpose, we performed an unsupervised, label-free, spatially resolved shotgun proteomics guided by MALDI mass spectrometry imaging (MSI) on 124 selected tumor clonal areas from early luminal breast cancers, tumor stroma, and breast cancer metastases. 2868 proteins were identified. The main protein classes found in the clonal proteome dataset were enzymes, cytoskeletal proteins, membrane-traffic, translational or scaffold proteins, or transporters. As a comparison, gene-specific transcriptional regulators, chromatin related proteins or transmembrane signal receptor were more abundant in the TCGA dataset. Moreover, 26 mutated proteins have been identified. Similarly, expanding the search to alternative proteins databases retrieved 126 alternative proteins in the clonal proteome dataset. Most of these alternative proteins were coded mainly from non-coding RNA. To fully understand the molecular information brought by our approach and its relevance to drug target discovery, the clonal proteomic dataset was further compared to the TCGA breast cancer database and two transcriptomic panels, BC360 (nanoString®) and CDx (Foundation One®). We retrieved 139 pathways in the clonal proteome dataset. Only 55% of these pathways were also present in the TCGA dataset, 68% in BC360 and 50% in CDx. Seven of these pathways have been suggested as candidate for drug targeting, 22 have been associated with breast cancer in experimental or clinical reports, the remaining 19 pathways have been understudied in breast cancer. Among the anticancer drugs, 35 drugs matched uniquely with the clonal proteome dataset, with only 7 of them already approved in breast cancer. The number of target and drug interactions with non-anticancer drugs (such as agents targeting the cardiovascular system, metabolism, the musculoskeletal or the nervous systems) was higher in the clonal proteome dataset (540 interactions) compared to TCGA (83 interactions), BC360 (419 interactions), or CDx (172 interactions). Many of the protein targets identified and drugs screened were clinically relevant to breast cancer and are in clinical trials. Thus, we described the non-redundant knowledge brought by this clone-tailored approach compared to TCGA or transcriptomic panels, the targetable proteins identified in the clonal proteome dataset, and the potential of this approach for drug discovery and repurposing through drug interactions with antineoplastic agents and non-anticancer drugs.

Abstract
BACKGROUND Formalin-fixed paraffin-embedded (FFPE) tissue has been the gold standard for routine pathology for general and cancer postoperative diagnostics. Despite robust histopathology, immunohistochemistry, and molecular methods, accurate diagnosis remains difficult for certain cases. Overall, the entire process can be time consuming, labor intensive, and does not reach over 90% diagnostic sensitivity and specificity. There is a growing need in onco-pathology for adjunct novel rapid, accurate, reliable, diagnostically sensitive, and specific methods for high-throughput biomolecular identification. Lipids have long been considered only as building blocks of cell membranes or signaling molecules, but have recently been introduced as central players in cancer. Due to sample processing, which limits their detection, lipid analysis directly from unprocessed FFPE tissues has never been reported. METHODS We present a proof-of-concept with direct analysis of tissue-lipidomic signatures from FFPE tissues without dewaxing and minimal sample preparation using water-assisted laser desorption ionization mass spectrometry and deep-learning. RESULTS On a cohort of difficult canine and human sarcoma cases, classification for canine sarcoma subtyping was possible with 99.1% accuracy using "5-fold" and 98.5% using "leave-one-patient out," and 91.2% accuracy for human sarcoma using 5-fold and 73.8% using leave-one-patient out. The developed classification model enabled stratification of blind samples in <5 min and showed >95% probability for discriminating 2 human sarcoma blind samples. CONCLUSION It is possible to create a rapid diagnostic platform to screen clinical FFPE tissues with minimal sample preparation for molecular pathology.

Abstract
Abstract
Background
Breast cancer (BC) remains a leading cause of cancer-related death among women worldwide. The complexity of this disease, especially its heterogeneity, have prevented its eradication and driven resistance to treatments. To reach precision oncology to eradicate BC, therapy needs to be specific to each tumor clone. Yielding enough molecular information from tumor clones to identify new drug targets represents a technical challenge due to sample size limitation or loss of spatial resolution. Matrix-assisted laser desorption/ionization (MALDI) imaging mass spectrometry combined with microproteomics enables a spatially-resolved unlabeled tumor imaging of its protein distribution, thus revealing proteomic clones. Our aims were to analyze the clonal proteome of luminal breast cancers, and explore its potential to expand new drug target discovery and drug repurposing.
Methods
A retrospective study at the Comprehensive Cancer Centre Oscar Lambret (Lille, France) was conducted to analyze 76 FFPE luminal HER2 negative tumors: 52 primary tumors from patients with early BC and 24 BC metastases. Patients gave their informed consent and the study was approved by the local institutional review board. MALDI mass spectrometry imaging and spatially-resolved on-tissue shotgun microproteomics were performed on FFPE slides of tumor tissue to determine the proteomic profile of selected clones using nanoLC-MS & MS/MS. Protein identification was performed using MaxQuant software against the Uniprot database. Functional annotation and characterization of the identified proteins were performed using Panther software. Candidate druggable targets were searched using DrugCentral druggable genome database, and their druggability level was assessed using the classification by the Illuminating the Druggable Genome Knowledge Management Center. The clonal proteome dataset was compared to publically available TCGA, BC360, and CDx datasets.
Results
The clonal proteome analysis identified a total of 2868 different proteins; 780 proteins were found in more than 50% of the patients. Panther analysis showed that 22% of the proteins were classified as enzymes, 15% were related to DNA processes, 6% were structural proteins, and less than 2% were related to immunity. Panther identified 139 pathways in the clonal proteome dataset. The clonal proteome analysis yielded the highest number of pathways compared to TCGA, BC360, and CDx datasets. 41 pathways (mainly metabolic pathways) were exclusive to the clonal proteome dataset. 1495 proteins of this dataset had an entry and were druggable in DrugCentral database, with 52% of them with known mechanisms of action and drug interaction. The main target classes were enzymes (60%), kinases (23%) and transporters (7%), whereas kinases were dominant in TCGA, BC360, and CDx datasets (46% to 77%). To explore the clonal proteome potential for repurposing anticancer drugs in luminal breast cancers, protein targets matching approved antineoplastic agents were searched using DrugCentral database. 97 approved anticancer drugs were identified, mostly chemotherapy (33%) or protein kinase inhibitors (28%), of whom only 17 were approved for breast cancer treatment. Compared to publically available TCGA, BC360, and CDx datasets, the clonal proteome analysis yielded the highest number of drug target candidate.
Conclusion
Mass spectrometry-based analysis of BC proteomic clones provides the technological means to access large functional molecular information at a clonal level to develop clone specific strategies for drug target discovery and drug repurposing in BC.

Abstract
e13063 Background: Breast cancer mortality is expected to rise by almost 30% by 2030 worldwide, mainly due to the occurrence of distant metastases. The development of drugs specifically targeted at tumor drivers has not yet curbed resistance to treatment, which prevents metastases curability. There is a need for new molecular approaches to tackle metastases complex biology, particularly tumor heterogeneity, a main determinant of resistance. The aim of this study was to use a proteomic mass spectrometry-based approach to reveal functionally heterogeneous’ tumor subpopulations in breast cancer metastases, and identify clone specific drug targets. Methods: Metastasis biopsies (n = 21) were collected retrospectively from patients with advanced breast cancer treated at Oscar Lambret Cancer Center (Lille, France). Tumor heterogeneity was analyzed directly on FFPE tissue sections using MALDI mass spectrometry imaging (MSI) on a RapifleX Tissuetyper. Unsupervised spatial segmentation was performed to reveal tumor subpopulations with distinct proteomic profiles within each metastasis. The full proteomic characterization of these tumor clones was further performed with spatially resolved proteomic mass spectrometry. Results: MSI revealed that breast cancer metastases contained 2 to 5 functionally distinct tumor clones (proteomic clones). Although the clone profiles within a metastasis were correlated, unsupervised hierarchical clustering showed a clear distinction between them and specific proteomic signatures. Enrichment analysis showed that differentially expressed proteins were involved in a variety of biological processes or pathways including regulation of histone acetylation, extracellular matrix degradation, DNA repair, NOTCH pathway, estrogen-responsive target genes or exocytosis. The evolution of the proteomic clones profile during disease progression was also determined by comparison of paired biopsies. To identify the candidate treatments best fitted to metastasis heterogeneity, the specific proteomic signatures of the clones were matched against a druggable genome database. It was possible to unveil candidate drug targets personalized to each metastasis functional clone. Conclusions: MALDI mass spectrometry imaging combined with spatially resolved proteomics has the potential to tackle breast cancer metastases heterogeneity, and identify candidate drug targets specific to functional clones to personalize treatments.

Abstract
3077 Background: Breast cancer is a heterogeneous disease with a wide range of outcomes. Among the intrinsic breast cancer subtypes, luminal A tumors are considered to have a favorable prognosis. However, molecular studies characterizing the genomic landscape of luminal A tumors revealed a molecular heterogeneity within this subtype, which also translated to variability in survival. A better understanding of the biology of this tumor subgroup is therefore needed to determine the appropriate therapeutic strategy. The aims of the study were to determine the frequency of high-risk luminal A tumors in a real life cohort of early breast cancers and provide a proteomic characterization of this subgroup using a mass spectrometry approach. Methods: 222 early breast cancer patients with hormone receptor positive and HER2 negative tumors treated at our institution had a PAM50-based genomic assay Prosigna to estimate their risk of recurrence. This assay assigned each tumor sample to an intrinsic molecular subtype of breast cancer. Luminal A and B tumors were analyzed with MALDI mass spectrometry imaging combined with microproteomics, a spatially-resolved on-tissue shotgun proteomic technology, to determine the proteomic profiles of both cancer cells and stroma. Results: Among the 129 luminal A breast cancers identified in our cohort, 67 (51%) had a risk of distant recurrence of 10% or more (32% had a 10% to 15% risk, and 19% a risk greater than 15%). High-risk luminal A tumors had a distinctive proteomic profile compared to low-risk luminal A or to luminal B tumors. Overexpression of the methionine biosynthesis pathway was the main differential protein expression observed in cancer cells and stroma of high-risk luminal A. Inflammation mediated by chemokine and cytokine signaling pathway and integrin signaling were also overexpressed in high risk luminal A compared to luminal B. In the stroma of luminal B tumors, EGR signaling, Ras and FGF pathways and angiogenesis were overexpressed compared to high-risk luminal A tumors. Conclusions: Real life data showed a significant proportion of high-risk luminal A breast cancers. MALDI mass spectrometry proteomics revealed distinctive tumor and microenvironment profiles in this breast cancer subgroup.

Abstract
Abstract
Background
Metastases from breast cancers have not yet reached curability mainly because of the continuous evolution of cancer cells leading to treatment resistance and tumor progression. Despite the identification of the main genomic drivers of breast cancer resistance, and the development of specific targeted therapies, resistance has not been eradicated. A deeper understanding of tumor biology underlying treatment escape and tumor progression is necessary to find new targets. The aim of this study was to determine whether mass spectrometry based imaging and microproteomics are able to capture changes in protein expression and pathways occurring during metastasis progression.
Methods
Ten tumor samples from five progressing metastatic breast cancer patients treated at Oscar Lambret Cancer Center (France) were selected based on the availability of paired metastasis biopsy performed at two time points during the evolution of the disease. The proteomic profiles of paired tumor samples were analyzed using MALDI mass spectrometry imaging combined with microproteomics, a spatially resolved proteomic technology.
Results
Comparison of paired samples showed gain and loss of proteins associated with tumor progression. However, few were shared between patients. The pathways and biological processes mainly represented during tumor progression, and which were found in at least two patients, were those involved in the negative regulation of leukocyte mediated cytotoxicity, the metabolism of carboxilic acid, peptides and nucleosides, in response to stress, oxidation-reduction process, endocytosis, catabolic processes, actin regulation, and extracellular matrix organization. During metastasis evolution, few shared proteins were identified in at least 3 patients such as SRPX2, CILP1, collagen alpha-2(V) chain, Ras-related C3 botulinum toxin substrate 1, filamin-C, PDZ and LIM domain protein 2 and chloride intracellular channel protein 4. The main proteins lost during progression and found in at least 2 patients were cell surface glycoprotein MUC18, collagen alpha-2(IV) chain, polyadenylate-binding protein 2, and latent-transforming growth factor beta-binding protein 4 (LTAGP4). Results from an expanded cohort will be presented at the meeting.
Conclusion
MALDI mass spectrometry proteomics identified private and shared changes in proteins and biological processes associated with breast cancer metastasis progression.

Abstract
Abstract
Background
Breast cancer is a heterogeneous disease with a wide range of outcomes that are not fully predicted by routine clinical and pathologic features. The risk of recurrence of hormone receptor positive early-stage breast cancer, the most frequent tumor subtype, increases continuously over time. Genomic-based signatures have been developed to categorize patients according to their risk of recurrence and guide therapeutic decisions in this tumor subtype. However, the main genomic-based assays used in clinical practice classify up to 40% of the patients in an intermediate risk group. Many interrogations remain about the optimal strategy in this group. The aim of this study was to refine the molecular characterization of the intermediate risk group and determine the proportion of shared features with the low or high-risk groups using a mass spectrometry based proteomic approach.
Methods
Tumors with available routine PAM50 assay (PROSIGNA) results were selected from a cohort of breast cancer patients treated at Oscar Lambret Cancer Center (France). Fifteen tumors evenly split between PAM50 low, intermediate and high-risk groups were analyzed to determine the proteomic profiles of both cancer cells and stroma using MALDI mass spectrometry imaging combined with microproteomics, a spatially resolved proteomic technology.
Results
PAM50-Intermediate risk tumors had a distinctive proteomic profile compared to low and high-risk tumors. Heterogeneous nuclear ribonucleoproteins, 4-aminobutyrate aminotransferase, and pleckstrin homology-like domain family A member 1 are discriminating proteins between intermediate risk and low risk tumors. Differences were observed in expression of integrin beta-1, DNA replication licensing factors, splicing factors and interleukin enhancer-binding factor 2 between intermediate and high-risk tumors. Proteomic profiles of stroma according to tumor risk groups also showed differential protein expressions mainly between intermediate and high-risk groups. Breast cancer markers such as nuclear mitotic apparatus protein 1(NUMA1), C-1-tetrahydrofolate synthase (MTHFD1), cystatin-C (CST3), and T-cell immune regulator 1 (TCIRG1) were identified in high-risk tumors. Specific protein profiles were identified in stroma versus tumor. Immunoglobulin kappa chain, IGHG1, IGHM, IGHM, MMP2, ORM1 & ORM2, podocan, asprorin, immunoglobulin superfamily containing leucine-rich repeat protein (ISLR) were detected in stroma. By contrast, squamous cell carcinoma antigen recognized by T-cells 3 (SART3), shootin-1, mitotic checkpoint protein BUB3, XRCC5 &XRCC6, membrane-associated progesterone receptor component 2 (PGRMC) and hepatocyte growth factor-regulated tyrosine kinase substrate (HGS) were specifically detected in tumor. Further analyses on an expanded cohort of patients will be presented.
Conclusion
MALDI mass spectrometry proteomics reveal distinctive tumor and microenvironment profiles in PAM50 intermediate risk early breast cancers.

Abstract
The aims of this study were to determine depuration rates for a range of per- and polyfluoroalkyl substances (PFASs) using Chironomus riparius, and to test a concentration-dependency hypothesis for the long-chain perfluorotridecanoic acid (PFTrDA) for this species. Midge larvae were exposed to field sediments collected downstream of a fluorotelomer plant, and to the same sediment spiked with PFTrDA. Elimination kinetics results indicated complete elimination of all PFASs by chironomids after 42h. These data were used to develop two PFTrDA bioaccumulation models accounting for chironomid growth and for compound concentration dependency or not. There was much better agreement between observed and simulated data under the concentration-dependency hypothesis than under the alternative one (passive diffusion). The PFTrDA uptake rate derived from the concentration-dependency model equaled 0.013 ± 0.008gocgwwh-1, and the depuration rate 0.032 ± 0.009h-1.

Abstract
Purpose To compare the safety and efficacy of a new enhanced viscosity ophthalmic formulation of tobramycin, given twice daily (BID), with the existing four times daily (QID) treatment regimen in patients with acute bacterial conjunctivitis. Methods This was a 12-day, multicenter, observer-masked, randomized, parallel group study. Patients received one drop of tobramycin 0.3% (3 mg/mL) enhanced viscosity ophthalmic solution BID or tobramycin 0.3% (3 mg/mL) ophthalmic solution QID in the affected eyes for 7 days. The primary efficacy variable was the percentage of patients with sustained cure/presumed bacterial eradication based on clinical judgment at the test-of-cure visit (Day 12). Pretherapy bacterial isolates were obtained and tested for susceptibility to tobramycin by determination of minimum inhibitory concentrations (MIC). Results A total of 276 patients were enrolled in the study and 203 of these were culture positive and attended all follow-up examinations. In this group, 98% of those treated with tobramycin enhanced viscosity ophthalmic solution and 99% of those treated with tobramycin 0.3% ophthalmic solution were categorized as having sustained cure/presumed eradication at the test-of-cure visit (p=0.6037). Reported adverse events were not serious, mild to moderate in severity, and generally did not prevent continuation in the study. Several pretreatment pathogens demonstrated tobramycin resistance (MIC > 4 mg/mL). However, therapy with both treatments was effective in the majority of the cases. Conclusions Tobramycin enhanced viscosity ophthalmic solution is well tolerated and has equivalent efficacy to the established treatment regimen with a simplified posology. The formulation provides an alternative therapy for acute bacterial conjunctivitis that should improve patient compliance and satisfaction.

Abstract
Aconitum karacolicum from northern Kyrgyzstan (Alatau area) contains about 0.8-1% aconitine as well as other aconite derivatives that have already been identified. In this paper, we compare several methods for the further purification of an Aconitum karacolicum extract initially containing 80% of aconitine. Reverse-phase flash chromatography, reverse-phase semi-preparative HPLC, centrifugal partition chromatography (CPC) and recrystallization techniques were evaluated regarding first their efficiency to get the highest purity of aconitine (over 96%) and secondly their applicability in a semi-industrial scale purification process (in our case, 150g of plant extract). Even if the CPC technique shows the highest purification yield (63%), the recrystallization remains the method of choice to purify a large amount of aconitine as i) it can be easily carried out in safe conditions; ii) an aprotic solvent is used, avoiding aconitine degradation. Moreover, this study led us to the identification of lappaconitine in Aconitum karacolicum, a well-known alkaloid never found in this Aconitum species.

Abstract
Gammarids were exposed to sediments from a deposition site located on the Rhône River (France) downstream of a fluoropolymer manufacturing plant. Gammarids accumulated to various extents four long-chain perfluoroalkyl carboxylic acids (PFCAs) from C9 to C13, one sulfonate, perfluorooctane sulfonate (PFOS) and three of its precursors (the perflurooctane sulfonamide (FOSA), the N-methyl perfluorooctane sulfonamidoacetic acid (MeFOSAA), the N-ethyl perfluorooctane sulfonamidoacetic acid (EtFOSAA) and the 6:2 fluorotelomer sulfonic acid (6:2 FTSA). Whatever the compound, the steady state was not achieved after a 3-week exposure; elimination was almost complete after a 3-week depuration period for perfluorononanoic acid (PFNA), PFOS, the three precursors and the 6:2FTSA. However, this was not the case for long-chain PFCAs, whose elimination rates decreased with increasing chain length. PFAS accumulation in gammarids occurred via the trophic and respiratory pathways, in proportions varying with the carbon chain length and the terminal moiety.

Abstract
Tumor blood vessels participate in the immune response against cancer cells and we previously used pre-clinical models to demonstrate that egfl7 (VE-statin) promotes tumor cell evasion from the immune system by repressing endothelial cell activation, preventing immune cells from entering the tumor mass. In the present study, the expression levels of egfl7 and that of ICAM-1 as a marker of endothelium activation, were evaluated in peritumoral vessels of human breast cancer samples. Breast cancer samples (174 invasive and 30 in situ) from 204 patients treated in 2005 were immunostained for CD31, ICAM-1 and stained for egfl7 using in situ hybridization. The expression levels of ICAM-1 and egfl7 were assessed in peritumoral areas using semi-quantitative scales. There was a strong and significant inverse correlation between the expression of ICAM-1 and that of egfl7 in CD31+ blood vessels. When the ICAM-1 score increased, the egfl7 score reduced significantly (P=0.004), and vice-versa (Cuzick's test for trend across ordered groups). In order to determine which gene influenced the other gene between egfl7 and ICAM-1, the expression levels of either gene were modulated in endothelial cells. Egfl7 regulated ICAM-1 expression while ICAM-1 had no effects on egfl7 expression in the same conditions. Altogether, these results provide further results that egfl7 serves a regulatory role in endothelial cell activation in relation to immune infiltration and that it is a potential therapeutic target to consider for improving anticancer immunotherapies.

Abstract
Midge larvae (Chironomus riparius) were exposed to sediments from a deposition sampled at a site along the Rhône River (France) downstream of an industrial site releasing various perfluorinated chemicals. This sediment is characterized by high concentrations of perfluoroundecanoic acid (PFUnA) and perfluorotridecanoic acid (PFTrDA) and a low perfluorooctane sulfonate (PFOS) concentration. Concentrations of 23 perfluoroalkyl compounds, including C4-C14 carboxylate acids, C4-C10 sulfonates, and seven precursors, were analyzed in overlying and pore water, sediment, and larvae. Midge larvae accumulated carboxylate acids (C11-C14), PFOS, and two precursors (perfluorooctane sulfonamide: FOSA and 6:2 fluorotelomer sulfonic acid, 6:2 FTSA). These substances accumulated mainly during the fourth instar larvae exponential growth phase. Accumulation of 6:2 FTSA, PFUnA, and PFOS occured via trophic and tegumentary routes. Other compounds mainly accumulated from food. Kinetics followed a partition model, from which uptake and elimination constants were derived.

Abstract
The craniopharyngioma is a benign intracranial nonglial tumor derived from a malformation of the embryonic tissue. Represents approximately 6-9% of brain tumors in children. It grows close to the optic nerve, hypothalamus and pituitary. The most frequent histological variety in children is adamantinomatous. The initial symptoms of intracranial hypertension is headache and nausea, followed by visual disturbances, impaired hormonal changes such as the secretion of GH, gonadotropins, TSH and ACTH and central diabetes insipidus. We present the clinical case of MD, 5yrs at age, which shows signs of intracranial hypertension syndrome: neuroradiological findings raise the diagnosis of adamantinomatous craniopharyngioma for which the child underwent to sub-total surgical removal of the lesion and radiosurgery treatment. During the disease develops visual impairment, and secondary diabetes insipidus, hypothyroidism hipocotisolism that takes therapy with desmopressin (Minirin), Cortone acetate and L-tiroxine. For the failure of previous therapies, the child has performed chemotherapy with cisplatin (30 mg/sqm/day) and Etoposide (150 mg/mq/day). A year after the end of the last cycle of chemotherapy was detected new progression of the lesion with the appearance of worsening headache and vomiting in the upright position. TC notes the expansion of the third ventricle and the patient undergoes surgery craniotomy. This clinical case underlines the difficulties in treatment of recurrent craniopharyngioma in situations where the anatomical location do not permit aggressive radical surgery. Anyway, new studies are needed to evaluate the effectiveness of systemic chemotherapy as a method of experimental treatment that could reduce the progression of disease.

Abstract
INTRODUCTION Patella alta is one of the primary factors of patellofemoral instability and its importance lies in the reduced engagement between patella and trochlea during the early degrees of flexion. The evaluation of patellar height is based on conventional x-rays, CT scan and, more recently, MRI. The objective of this multicentric prospective study is to describe a novel index to assess in the sagittal plane the functional engagement between patella and trochlea. MATERIALS AND METHODS One hundred and thirty-five patients with objective patellar dislocation were prospectively enrolled between April 2010 and September 2011 and were compared with a second group of 45 controls. All patients underwent a standard MRI and a complete radiographic study. Sagittal engagement was measured as the ratio between the articular cartilage of the patella and the trochlear cartilage length measured on two different MRI slices. RESULTS The mean Sagittal Patellofemoral Engagement (SPE) index was 0.43 ± 0.18 and ranged from 0.02 to 0.913 in the Objective Patellar Dislocation group versus 0.42 ± 0.11 range 0.22 to 0.55 in controls. In the Patellar Dislocation group the mean Caton-Deschamps index was 1.18 ± 0.21 (range 0.71 to 1.91). There were 58 patients with patella alta, in whom the mean SPE was 0.39 ± 0.18 (range 0.02 to 0.87). Sagittal engagement was significantly higher when compared with patients in the Patellar Dislocation group who had no patella alta (mean 0.46 ± 0.16, range 0.1-0.913). DISCUSSION The present study introduces a new method to measure the SPE with the use of MRI. The evaluation of the functional engagement of the patella with the femoral trochlea in the sagittal plane can serve as a supplementary tool to the existing methods of evaluating patellar height, and may help to better identify the cases where inadequate engagement is recorded despite the absence of patella alta, so that the need for tibial tuberosity osteotomy may be re-assessed.

Abstract
INTRODUCTION The aim of this study was to define a new index to measure lateral patellar displacement (LPD) using nuclear magnetic resonance imaging (MRI), an axial index of engagement of the patella (AEI) obtained from two different axial MRI views then to validate its use in a prospective series of patients presenting an objective patellar instability (OPI). MATERIALS AND METHODS One hundred and thirty-five patients with OPI and no history of surgery of the patella were included in a prospective study organized by the French Society of Arthroscopy performed between June 2010 and August 2012. All patients underwent axial and sagittal MRI. The AEI was obtained by projecting predefined patellar and trochlear landmarks (cartilaginous landmarks) on 2 different axial MRI views (one trochlear and one patellar). The results were compared with a series of controls (n=45). RESULTS The preoperative AEI of the patella was 0.94 ± 0.09 for the control group and 0.84 ± 0.16 for OPI group (P=0.000016). The AEI could be obtained in 100% of the cases if it was measured on 2 MRI views while it could not be measured in 38.5% of the cases if the measurement was only obtained from one MRI view or whenever the widest part of the patella was not across from the femoral trochlea. The AEI did not significantly depend on dysplasia or the presence of a supratrochlear spur. The lowest AIE values were associated with trochlear dysplasia with a supratrochlear spur (P=0.0023) and a more prominent trochlea (P=0.0016). The AEI was correlated with patellar tilt (P<0.000001) and TT-TG on MRI (P<0.000001). DISCUSSION AEI is a new index to measure LPD. It can be obtained in all cases because it is obtained from two different MRI views. The normal value is close to 1. It can be used to measure patellar instability on the axial plane in patients with OPI, especially in the most severe cases.

Abstract
Block copolymers form nanostructures that have interesting physical properties because they combine, for a single compound, the complementary features brought by each block. However, in order to fully exploit these properties, the physical state of each kind of domain must be precisely controlled. In this work, triblock PS-b-PEO-b-PS copolymers consisting of a central poly(ethylene oxide) (PEO) block covalently bonded to polystyrene (PS) blocks were synthesized by Atom Transfer Radical Polymerization. Their morphology was investigated by X-ray scattering and TEM experiments whereas their thermodynamic behavior was characterized by DSC. A strong decrease of both the melting temperature and the degree of crystallinity of PEO, due to its confinement between the PS domains, was observed and analyzed with a modified Gibbs-Thomson equation, following the approaches used for fluids confined in porous media. The existence of an amorphous bound layer, a few nanometers thick, at the PEO/PS interface, that does not undergo any phase transition in the temperature range investigated, accounts for both the melting temperature depression and the decrease of crystallinity upon confinement. This interfacial layer may significantly affect the mechanical and transport properties of these block copolymers that find applications as solid polymer electrolytes in batteries for example. Moreover, the value obtained for the solid PEO/liquid PEO surface tension is lower than those previously published but is thermodynamically consistent with the surface tensions of polymers at the solid/vapor and liquid/vapor interfaces.

Abstract
PURPOSE Anti-tissue transglutaminase antibodies (ATTG) have helped to distinguish atypical and silent clinical forms of celiac disease (CD). Immunological diagnosis or follow-up of the disease is now based in France in first line upon IgA ATTG serum evaluation. In the University Hospital of Marseille, the serological diagnosis of CD had consisted during several years in simultaneous determination of both IgA anti-endomysial antibodies (AEA) and IgA ATTG. In literature, few studies focused on the concordance between the two tests and a very few epidemiological data about CD in France are available. METHODS Five thousand nine hundred and eighty-one patients for whom both AEA and ATTG testing were available were retrospectively included. Characteristics of this cohort were detailed. We numbered and analyzed especially bioclinical charts from patients with AAE/AATG discordance. RESULTS Among our patients, all ages and all medical subspecialties were represented. Eighty-five new cases of CD were identified. Among the 6516 serum evaluations performed, only 31 tests were discordant. CONCLUSIONS Our data give information about CD epidemiology in France. They support the contention that ATTG have to be evaluated in first line for CD diagnosis.

Abstract
As all arthropods, microcrustaceans shed their chitinous exoskeleton (cuticule, peritrophic membrane) to develop and grow. While the molting is the most crucial stage in their life cycle, it remains poorly investigated in term of pollutant biodistribution within the organisms. In this paper, we used optical, electronic, and X ray-based microscopies to study the uptake and release of CeO2 nanoparticles by/from Daphnia pulex over a molting stage. We measured that D. pulex molts every 59 ± 21 h (confidence interval) with growth rates about 1.1 or 1.8 μm per stage as a function of the pieces measured. Ingestion via food chain was the main route of CeO2 nanoparticles uptake by D. pulex. The presence of algae during the exposure to nanoparticles (sub-lethal doses) enhanced by a factor of 3 the dry weight concentration of Ce on the whole D. pulex. Nanoparticles were localized in the gut content, in direct contact with the peritrophic membrane, and on the cuticle. Interestingly, the depuration (24 h with Chlorella pseudomonas) was not efficient to remove the nanoparticles from the organisms. From 40% to 100% (depending on the feeding regime during exposure) of the CeO2 taken up by D. pulex is not release after the depuration process. However, we demonstrated for the first time that the shedding of the chitinous exoskeleton was the crucial mechanism governing the released of CeO2 nanoparticles regardless of the feeding regime during exposure.

Abstract
OBJECTIVE Brainstem tumors (BSTs) are usually gliomas and are divided into diffuse BSTs (DBSTs) and focal BSTs (FBSTs). The aim of this study is to investigate the different outcomes of these two entities. METHODS Thirty-one patients with BSTs were admitted to our institution from 1995 to 2003. Patients with DBSTs were treated with locoregional radiotherapy (1.8 Gy/day for 54 Gy) and weekly vincristine for radiosensitization (1.5 mg/sm for six total doses). Patients with FBSTs underwent surgical resection. Chemotherapy and/or radiotherapy were considered in progression. RESULTS AND CONCLUSIONS Fourteen patients were diagnosed as having DBSTs. The responses to treatment were ten cases of partial response, three of stable disease, and one of progressive disease. General and/or neurological symptoms improved in more than 80% of patients. The median time from diagnosis to progression and to death were, nonetheless, 8 (range of 3-13) and 13 (range of 4-25) months, respectively, with a 2-year overall survival rate of 12.3% [standard error (SE) 11.2]. Seventeen patients were diagnosed as having FBSTs. Gross total removal was achieved in 4/17 cases, subtotal removal in 7/17, and partial removal in 6/17. There was one surgery-related death. Eight out of 17 patients had adjuvant chemo- and/or radiotherapy after progression: 6/8 are without neurological symptoms and 2/8 have died due to tumor progression. The 4-year overall and disease-free survival rates are 87.4 (SE 8.4) and 58.8% (SE 11.9), respectively, the extent of resection being the most important prognostic factor (p=0.012). DBSTs continue to carry a dismal prognosis, thus demanding new treatment modalities; FBSTs can be treated surgically and patients benefit from a better prognosis.

Abstract
PURPOSE To compare the safety and efficacy of a new enhanced viscosity ophthalmic formulation of tobramycin, given twice daily (BID), with the existing four times daily (QID) treatment regimen in patients with acute bacterial conjunctivitis. METHODS This was a 12-day, multicenter, observer-masked, randomized, parallel group study. Patients received one drop of tobramycin 0.3% (3 mg/mL) enhanced viscosity ophthalmic solution BID or tobramycin 0.3% (3 mg/mL) ophthalmic solution QID in the affected eyes for 7 days. The primary efficacy variable was the percentage of patients with sustained cure/presumed bacterial eradication based on clinical judgment at the test-of-cure visit (Day 12). Pretherapy bacterial isolates were obtained and tested for susceptibility to tobramycin by determination of minimum inhibitory concentrations (MIC). RESULTS A total of 276 patients were enrolled in the study and 203 of these were culture positive and attended all follow-up examinations. In this group, 98% of those treated with tobramycin enhanced viscosity ophthalmic solution and 99% of those treated with tobramycin 0.3% ophthalmic solution were categorized as having sustained cure/presumed eradication at the test-of-cure visit (p = 0.6037). Reported adverse events were not serious, mild to moderate in severity, and generally did not prevent continuation in the study. Several pre treatment pathogens demonstrated tobramycin resistance (MIC > 4 mg/mL). However, therapy with both treatments was effective in the majority of the cases. CONCLUSIONS Tobramycin enhanced viscosity ophthalmic solution is well tolerated and has equivalent efficacy to the established treatment regimen with a simplified posology. The formulation provides an alternative therapy for acute bacterial conjunctivitis that should improve patient compliance and satisfaction.

Abstract
OBJECTIVE To publish our experience in the management of Meckel's diverticula in adults, and compare our results with those published elsewhere. DESIGN Retrospective investigation of casenotes. SETTING Multicentre study, Switzerland. SUBJECTS 119 patients aged over 16 years who had Meckel's diverticula resected between 1980 and 1997. MAIN OUTCOME MEASURES Assessment of the usefulness of various investigations and the criteria for removing asymptomatic diverticula. RESULTS 67 diverticula (56%) were resected during laparotomy for another cause, and 52 (44%) for symptoms caused by the diverticula. In both groups the condition was more common in men, and most likely to present during the fourth decade. The most common investigation in the 52 symptomatic cases was a plain film of the abdomen (n = 47, 90%), and in none was a Meckel's diverticulum suggested as the cause of the symptoms. The success rates of other investigations were: small bowel enema 4/9, 99mTc scan 3/4, angiography 1/3, and computed tomography 1/14. No ultrasound scans were done. Our results compared favourably with those reported elsewhere, with no deaths in either group, 2 complications that required reoperation in the incidental group, and 1 in the symptomatic group. CONCLUSIONS The criteria to be taken into account when deciding to resect an asymptomatic diverticulum are: male sex, age <40, ASA score, the operation being done, the size and position of the diverticulum, whether it is palpable, and whether there are other reasons for the patient's complaints.

Abstract
OBJECTIVE Approximately one out of five patients with Graves' disease (GD) undergoes a thyroidectomy after a mean period of 18 months of medical treatment. This retrospective and non-randomized study from a teaching hospital compares short- and long-term results of total (TT) and subtotal thyroidectomies (ST) for this disease. METHODS From 1987 to 1997, 94 patients were operated for GD. Thirty-three patients underwent a TT (mostly since 1993) and 61 a ST (keeping 4 to 8 grams of thyroid tissue--mean 6 g). All patients had received propylthiouracil and/or neo-mercazole and were in a euthyroid state at the time of surgery; they also took potassium iodide (lugol) for ten days before surgery. RESULTS There were no deaths. Transient hypocalcemia (< 3 months) occurred in 32 patients (15 TT and 17 ST) and persistent hypocalcemia in 8 having had TT. Two patients developed transient recurrent laryngeal nerve palsy after ST (< 3 months). After a median follow-up period of seven years (1-15) with five patients lost to follow-up, 41 patients having had a ST are in a hypothyroid state (73%), thirteen are euthyroid (23%), and two suffered recurrent hyperthyroidism, requiring completion of thyroidectomy. All 33 patients having had TT--with follow-ups averaging two years (0.5-8)--are receiving thyroxin substitution. CONCLUSIONS There were no instances of persistent recurrent laryngeal nerve palsy in either group, but persistent hypoparathyroidism occurred more frequently after TT. Long after ST, hypothyroidism developed in nearly three of four cases, whereas euthyroidy was maintained in only one-fourth; recurrent hyperthyroidy was rare.

Abstract
The recent development of endoscopic surgery and its use in treating several abdominal and thoracic surgical pathologies lead us to suggest its application in the treatment of posttransplant lymphoceles. The authors report two cases treated by the laparoscopic approach. Recurrence occurred in one of them. The technique is described and its place among other therapeutic modalities is discussed.

Abstract
The pharmacokinetics and pharmacodynamics of rolafagrel (FCE 22178), a novel thromboxane synthase inhibitor, were evaluated after single and multiple oral doses in eight healthy volunteers. After a single dose (400 mg), the drug was absorbed rapidly, peak plasma concentrations being attained within 2 h in all subjects. Elimination followed a biphasic course, with a rapid initial decline followed after 12-24 h by a late phase with a terminal half-life of about 10 h. About 100% of the administered dose could be recovered in urine within 72 h, mostly in conjugated form. During multiple dosing (400 mg t.i.d. for 5 days), steady-state conditions were approached on day 2 and AUC values over a dosing interval were similar to those observed after a single dose (72.3 vs 76.3 micrograms.ml-1.h). Pharmacokinetic parameters calculated after multiple doses were similar to those observed after a single dose (Cmax: 20.1 vs 18.2 micrograms.ml-1; tmax: 1.2 vs 1.1 h; terminal half-life: 10.9 vs 11.4 h; CL: 85.2 vs 70.4 ml.h-1.kg-1; V: 1.23 vs 1.24 l.kg-1). Platelet generation of thromboxane B2, the stable breakdown product of thromboxane A2, was inhibited by 85% at a plasma rolafagrel concentration of about 4 micrograms.ml-1, and only a small increase in inhibition was observed at higher concentrations.

Abstract
Flavonoids form an important family of compounds widely present in plants and therefore in food, sometimes as substitutes for synthetic antioxidants. Although the excretion routes of flavonoids in animals has been explored, little is known about the details of their conjugation in the xenobiotic metabolism pathway. In this study, we investigate the metabolism of diosmetin as a model compound in the rat, particularly its level in blood after treatment (100 mg/kg, po) and the presence of its glucuronide(s) in both blood and urine. We demonstrate that after po treatment of the rat, a rapid glucuronidation takes place and that diosmetin circulates as glucuronides, whereas no free diosmetin is present in blood and urine. The glucuronides formed are present in the blood plasma at a high level (approximately 10 micrograms/ml), for at least 6 hr after the treatment and the conjugates are excreted in urine. We have detected four different glucuronides in blood and characterized the two major ones after purification by a combination of MS, NMR, and UV spectroscopy: diosmetin-7,3'-diglucuronide and diosmetin-3'-glucuronide. A brief characterization of the in vitro glucuronidation of some flavonoid compounds using liver microsomal preparations suggests that this important class of natural compounds might be conjugated by a specific isoform of UDP-glucuronosyltransferase. Thus, this work brings evidence that diosmetin is rapidly glucuronoconjugated in the rat and provides an explanation for the low po bioavailability of the unchanged compound that can be generalized to this important class of natural compounds.

Abstract
Fenticonazole vaginal ovules of 200 mg, 600 mg and 1,000 mg were administered to 42 women prior to gynecological surgery. Tissue concentrations in the vaginal mucosa were determined after 3 h and 12 h in biopsy specimens taken from the same position in the posterior fornix. Tissue concentrations were higher at 3 h in comparison to 12 h with all 3 doses. There was no statistical difference between the concentrations yielded by the 3 different ovules at 3 h, while after 12 h the concentrations were dose-dependent and significantly higher after 1,000 mg in comparison to 200 mg, but not to 600 mg.

Abstract
Fifty-seven patients with spinal metastases underwent 60 operations. 36 patients were operated on by anterior approach with decompressive coporectomy and stabilization by metal and methylmetacrylate and 24 patients by laminectomy and/or stabilization by osteosynthesis. Postoperative improvement of the pain syndrome was observed after 56 operations. Neurologic signs were present in 23 patients with paraplegia (5 patients) or paraparesis (18 patients); 15 of the latter patients improved and recovered walking capacity. Two types of metastasis were distinguished: corporal metastasis, in which vertebral wedging and posterior protrusion led to neural deficit, with a good prognosis if treated by anterior surgery, and pericordal metastasis in which the cord compression is due to metastatic proliferation into the spinal canal. Results after decompressive surgery, either by posterior or anterior approaches are more doubtful. Surgery is beneficial and should be preferred to radiation when there is medullary compression by corporal metastasis and also in the presence of intense pain or potential instability of the spine.

Abstract
Two methods, using gas chromatography (GC) and high-performance liquid chromatography (HPLC), were developed in order to investigate the pharmacokinetics of denzimol hydrochloride, N-[beta-[4-(beta-phenylethyl)phenyl]-beta-hydroxyethyl] imidazole hydrochloride, which is a new anticonvulsant drug, and of its main metabolite, N-[beta-[4-(beta-phenyl-beta(alpha)-hydroxyethyl)phenyl] -beta-hydroxyethyl]-imidazole (referred to as M2), in humans. Both methods involve the use of a homologue of denzimol as an internal standard. The GC method is more sensitive (sensitivity limit 2.5 ng/ml for denzimol and 15 ng/ml for M2) and was utilized for the determination of denzimol and M2 in plasma. The GC method is specific, precise (relative standard deviations are 3.26, 2.12 and 1.72% at 10, 100 and 1000 ng/ml for denzimol and 6.45, 4.17 and 3.38% at 50, 500 and 1000 ng/ml for M2) and accurate (mean recovery +/- S.D. is 102.58 +/- 4.10% for denzimol and 99.72 +/- 7.75% for M2). The HPLC method is very simple and quick to perform. This method has a sensitivity limit of 0.5 micrograms/ml for denzimol and 1 microgram/ml for M2, and allows the determination of both compounds in urine with high selectivity, reproducibility (relative standard deviations are 2.05, 3.50 and 1.02% for denzimol and 2.78, 2.80 and 1.73% for M2, at concentrations of 15, 35 and 70 micrograms/ml) and accuracy (mean recovery +/- S.D. is 103.57 +/- 2.97% for denzimol and 95.91 +/- 1.59% for M2). The common anticonvulsants, when present in plasma, do not interfere with the monitoring of denzimol levels.

Abstract
The relationship between plasma, brain and cerebellum concentrations of Denzimol a new anticonvulsant agent, and its anticonvulsant and neurotoxic effects were studied in the rat. Sixty minutes after oral administration, a high brain/plasma concentration ratio of 10:1 was found. Mean plasma, brain and cerebellum half-lives of the drug were 8.4, 7.1 and 9.2 hr, respectively. The anticonvulsant activity of the drug was examined by maximal electroshok seizures (MES). Neurotoxicity was determined both by the rotarod performance test and by behavioural observation. Denzimol was effective against MES, in the ranges of 0.8-5 micrograms/ml and 10-50 micrograms/ml for plasma and brain concentrations, respectively, without causing clear signs of neurological toxicity. It is concluded that the anticonvulsant and neurotoxic effects of denzimol are correlated to its plasma and brain concentrations.
