Abstract
The most common form of facioscapulohumeral dystrophy (FSHD1) is caused by a partial loss of the D4Z4 macrosatellite repeat array in the subtelomeric region of chromosome 4. Patients with FSHD1 typically carry 1 to 10 D4Z4 repeats, whereas nonaffected individuals have 11 to 150 repeats. The ~150-kilobyte subtelomeric region of the chromosome 10q exhibits a ~99% sequence identity to the 4q, including the D4Z4 array. Nevertheless, contractions of the chr10 array do not cause FSHD or any known disease, as in most people D4Z4 array on chr10 is flanked by the nonfunctional polyadenylation signal, not permitting the DUX4 expression. Here, we attempted to correct the FSHD genotype by a CRISPR-Cas9-induced exchange of the chr4 and chr10 subtelomeric regions. We demonstrated that the induced t(4;10) translocation can generate recombinant genotypes translated into improved FSHD phenotype. FSHD myoblasts with the t(4;10) exhibited reduced expression of the DUX4 targets, restored PAX7 target expression, reduced sensitivity to oxidative stress, and improved differentiation capacity.

Abstract
PDZ domains are highly abundant protein-protein interaction modules in human. One of the most extensively characterized PDZ domain, the third PDZ domain from PSD-95 (PDZ3), contains an α-helical C-terminal extension that has a key role in the function of the domain. Here we compared the folding of PDZ3 with a truncated variant (PDZ3Δα3), lacking the additional helix, by means of the so-called Φ-value analysis, an experimental technique that allows inferring the structure of folding transition states. Experiments reveal subtle but detectable differences in the folding of PDZ3Δα3 versus PDZ3, as probed by structural characterization of the folding transition states. These differences appear more remarkable in the early stages of folding, with a detectable shift of the folding nucleus. The presented results allow demonstrating that the native state exerts a weak bias at the early stages of folding, which appear to be characterized by alternative pathways.

Abstract
Horse mares are frequently treated with the progestin altrenogest with the aim to suppress estrous behavior and its negative impact on equestrian performance. Progestogens, however, also have sedative effects in males, and females of different species. The aim of our study was therefore to investigate altrenogest-induced changes in the stress response of female horses during initial equestrian training. Three-yr-old Warmblood mares were randomly assigned to treatment with altrenogest (ALT; 0.044 mg/kg once daily; n = 6) or sunflower oil (CON; n = 5) for 12 wk during training. At predefined steps of the training program (free movement, lunging without and with side reins, lunging with saddle, mounting of a rider, free riding, riding by an unfamiliar rider) salivary cortisol concentration, and heart rate were determined from 60 min before to 120 min after training. The same procedures were performed during repeated gynecologic examinations and 2 novel object tests. Bodyweight and body condition scores (BCS) were assessed at 4-wk intervals. During all training units, salivary cortisol concentration and heart rate increased (P < 0.001), but the increase was smaller in group ALT mares (time x treatment P < 0.001). Gynecologic examinations and novel object tests induced a much smaller increase in cortisol and heart rate (P < 0.001) than equestrian training with no difference between groups ALT and CON. Initially, bodyweight, and BCS decreased during training. The subsequent increase was larger in group ALT vs CON (time x treatment P < 0.05). In conclusion, altrenogest reduced the stress response of 3-yr-old mares to equestrian training. The use of altrenogest during equestrian competitions should therefore be reconsidered.

Abstract
Blue light directed at 1 eye advances the equine ovulatory season but may also advance foaling. In this study, effects of blue LED light on pregnancy outcome were assessed. A total of 20 mares with singleton pregnancies were studied over 2 consecutive years in a cross-over design. In 1 year, mares received an extended photoperiod using 50 lux of blue LED light (468 nm) directed at a single eye from 08:00 until 23:00 daily via head-worn light masks starting mid-December and in the other year remained untreated as controls. Gestation was shorter in blue LED light-treated than in control pregnancies (median 333.0 vs 338.5 days, P = 0.036). Foals born to blue LED light-treated mares had lower wither heights (median 103.0 vs 104.5 cm, P = 0.023), similar weights (median 55.8 vs 54.8 kg, P = 0.732) and took less time to stand after birth than control foals (median 35.0 vs 53.5 min, P = 0.036). Foals born to blue LED light-treated mares had reduced hair length compared to controls (median 12.0 vs 20.0 mm, P = 0.009) and hair regrowth in treated mares was reduced (P = 0.036). In conclusion, blue LED light directed at 1 eye advanced foaling and influenced height and hair coat but not weight in foals.

Abstract
Work-related asthma (WRA) accounts for 10-25% of all adult asthma. It therefore seems important to raise questions regarding an asthmatic's approach to occupational or job training activities. WRA takes on two forms: work-exacerbated asthma (WEA) and occupational asthma (OA), which encompasses different subtypes of heterogeneous mechanisms. It currently represents a major challenge for occupational medicine in terms of detailed diagnosis, social care, the economic repercussions for workers and employers and, last but not least, social insurance. This review aims to sensitize health care practitioners to the peculiarities of WRA management in routine practice. More specifically, prognosis depends on early diagnosis, medical care and work adjustment measures. WEA and OA are explained in detail in view of identifying causative agents and at-risk occupations and defining adapted medical strategy. Relevant lines of questioning and complementary exams are presented. In addition, the key role of the occupational physician, especially as regards recognition and identification of occupational disease, is underlined, the objective being to facilitate optimal professional and social management. In future studies, the key role of counseling and orientation mechanisms should be highlighted as means of preventing WRA occurrence.

Abstract
Behavior during the estrous cycle of mares can affect their performance and therefore inhibition of cyclical ovarian activity is indicated. We hypothesized that implants containing the GnRH analog deslorelin downregulate GnRH receptors and inhibit ovulation in mares. The estrous cycles of Shetland mares were synchronized with 2 injections of a PGF2α analog. One day after the second injection (day 0), mares received 9.4 (group D1, n = 6) and 4.7 mg deslorelin (D2, n = 5) as slow-release implants or 1.25 mg short-acting deslorelin as a control (C, n = 5). Ultrasonography of the reproductive tract and ovaries and observation of estrous behavior and collection of blood samples for analysis of progesterone and LH concentrations were performed every second day until day 10 and thereafter at 5-d intervals. Stimulation tests with the GnRH-agonist buserelin were performed on days 10 and 45. Until day 50, there were less spontaneous ovulations in group D1 (P < 0.01) and estrous behavior was reduced in groups D1 and D2 compared with group C (P < 0.05). The time until first ovulation (D1 62.0 ± 8.6, D2 44.2 ± 14.1, C 22.2 ± 3.1 d, P < 0.05) and the number of days with estrous behavior (P < 0.05) differed among groups. On day 10 after treatment, a GnRH stimulation test revealed interactions between group and time (P < 0.001) in plasma LH concentration that were no longer detectable on day 45 after treatment. In conclusion, long-acting deslorelin implants result in a transient downregulation of pituitary GnRH receptors that is associated with inhibition of ovulation and estrous behavior in Shetland mares.

Abstract
Hearing is a mechanical and neurochemical process, which occurs in the hair cells of inner ear that converts the sound vibrations into electrical signals transmitted to the brain. The multi-PDZ scaffolding protein whirlin plays a critical role in the formation and function of stereocilia exposed at the surface of hair cells. In this article, we reported seven stereociliary proteins that encode PDZ binding motifs (PBM) and interact with whirlin PDZ3, where four of them are first reported. We solved the atomic resolution structures of complexes between whirlin PDZ3 and the PBMs of myosin 15a, CASK, harmonin a1 and taperin. Interestingly, the PBM of CASK and taperin are rare non-canonical PBM, which are not localized at the extreme C terminus. This large capacity to accommodate various partners could be related to the distinct functions of whirlin at different stages of the hair cell development.

Abstract
Oestrus behaviour in mares can contribute to problems in their handleability and reduced performance in equestrian sports. Therefore, methods of transient suppression of oestrous cyclicity in mares are of interest. The aim of our study was to determine whether treatment of mares with slow-release implants containing the gonadotrophin-releasing hormone (GnRH) analogue deslorelin downregulates pituitary GnRH receptors and reduces ovarian function and oestrous behaviour. Shetland mares (age=11.0±1.4 years; bodyweight=185.5±7kg) were oestrous synchronised with two injections of the prostaglandin F2α analogue luprostiol (3.725mg) at an interval of 12 days. One day after the second injection (Day 0), mares were randomly assigned to three groups: slow-release implant with 9.4mg of deslorelin (Suprelorin, Virbac; group D1; n=6), implant with 4.7mg of deslorelin (group D2; n=5), and intramuscular injection of 1.25mg of short-acting deslorelin (control, group C; n=5). Collection of blood samples for analysis of progesterone, LH, and anti-Müllerian hormone (AMH) using established and validated enzyme immunoassays (Scarlet et al. 2018 Theriogenology 117, 72-77), testing for oestrus-like behaviour with a Shetland stallion, and ultrasonography of the genital tract were performed at 2-day intervals until Day 10 after treatment and at 5-day intervals from there. On Days 10 and 45 after treatment, LH stimulation tests with the GnRH agonist buserelin (4µg IV) were performed. Data were normally distributed; differences among groups were analysed using analysis of variance and subsequent Tukey test. Values are means±s.e.m. In all mares without a corpus luteum on Day 0 (progesterone <1ngmL−1; one mare in group D1 and two in group C), ovulation was detected within 9 days after deslorelin treatment. These ovulations were classified as deslorelin induced, whereas ovulations after Day 10 were classified as spontaneous ovulations. The mean interval from deslorelin until the first spontaneous ovulation was 62.0±8.6, 44.2±14.1, and 22.2±3.1 days in groups D1, D2, and C (P<0.05), respectively. Subsequent oestrous cycles were regular. Oestrus-like behaviour until day 50 was reduced in groups D1 (2.0±0.9 days) and D2 (2.4±1.3 days) compared with group C (6.4±1.2 days; P<0.05). Concentration of plasma LH and AMH decreased in group D1 (P<0.05) but not in groups D2 and C. The GnRH stimulation test on Day 10 resulted in an increase (P<0.001) in plasma LH concentration in group C but not in groups D1 and D2 (treatment×time P<0.05). On Day 45, LH concentration increased in all mares in response to buserelin (NS among groups). Within 100 days of treatment, LH concentrations but not AMH concentrations in mares of group D1 returned to baseline. In conclusion, deslorelin slow-release implants transiently suppress ovarian function and oestrus behaviour in mares. Spontaneous ovulation is delayed in a dose-dependent manner. A decrease in AMH concentration suggests inhibitory effects of deslorelin on small antral follicles. Long-term effects on follicular dynamics and fertility in larger horses also need to be assessed.

Abstract
Acid sphingomyelinase deficiency (ASMD), also called Niemann-Pick disease, is a storage disorder with pulmonary involvement but few respiratory symptoms in adults. However, the disease may evolve towards clinically relevant respiratory symptoms with referral to the pulmonologist for management and care. Based on two case reports illustrating respiratory impairment, the aim of this work was to review clinical features, diagnosis, respiratory prognostic and therapeutics for the pulmonologist. Overall, storage disorder should be suspected in the presence of hepatosplenomegaly and interstitial lung disease. Concomitant thrombopenia or hyperlipidemia should also draw attention. Following recent consensus guidelines, diagnosis is based on enzyme assay for ASM activity in blood, with subsequent gene sequencing once the biochemical diagnosis has been confirmed. Disease is slowly progressive and the main causes of death are respiratory and liver failure. Presence of emphysema lesions or worsening of respiratory symptoms should call for the intensification of treatment. Though enzyme replacement therapy is a promising way of development, lung transplantation might be considered for these patients in the absence of contraindication.

Abstract
![]()
Targeted
approaches aiming at modulating NHERF1 activity, rather
than its overall expression, would be preferred to preserve the normal
functions of this versatile protein. We focused our attention on the
NHERF1/PDZ1 domain that governs its membrane recruitment/displacement
through a transient phosphorylation switch. We herein report the design
and synthesis of novel NHERF1 PDZ1 domain inhibitors. These compounds
have potential therapeutic value when used in combination with antagonists
of β-catenin to augment apoptotic death of colorectal cancer
cells refractory to currently available Wnt/β-catenin-targeted
agents.

Abstract
Ever since Ranganathan and coworkers subjected the covariation of amino acid residues in the postsynaptic density-95/Discs large/Zonula occludens 1 (PDZ) domain family to a statistical correlation analysis, PDZ domains have represented a paradigmatic family to explore single domain protein allostery. Nevertheless, several theoretical and experimental studies in the past two decades have contributed contradicting results with regard to structural localization of the allosteric networks, or even questioned their actual existence in PDZ domains. In this review, we first describe theoretical and experimental approaches that were used to probe the energetic network(s) in PDZ domains. We then compare the proposed networks for two well-studied PDZ domains namely the third PDZ domain from PSD-95 and the second PDZ domain from PTP-BL. Our analysis highlights the contradiction between the different methods and calls for additional work to better understand these allosteric phenomena.

Abstract
INTRODUCTION Obesity is a growing concern in horses. The effects of maternal obesity on maternal metabolism and low-grade inflammation during pregnancy, as well as offspring growth, metabolism, low-grade inflammation, testicular maturation and osteochondrotic lesions until 18 months of age were investigated. MATERIAL AND METHODS Twenty-four mares were used and separated into two groups at insemination according to body condition score (BCS): Normal (N, n = 10, BCS ≤4) and Obese (O, n = 14, BCS ≥4.25). BCS and plasma glucose, insulin, triglyceride, urea, non-esterified fatty acid, serum amyloid A (SAA), leptin and adiponectin concentrations were monitored throughout gestation. At 300 days of gestation, a Frequently Sampled Intravenous Glucose Tolerance Test (FSIGT) was performed. After parturition, foals' weight and size were monitored until 18 months of age with plasma SAA, leptin, adiponectin, triiodothyronine (T3), thyroxine (T4) and cortisol concentrations measured at regular intervals. At 6, 12 and 18 months of age, FSIGT and osteoarticular examinations were performed. Males were gelded at one year and expression of genes involved in testicular maturation analysed by RT-qPCR. RESULTS Throughout the experiment, maternal BCS was higher in O versus N mares. During gestation, plasma urea and adiponectin were decreased and SAA and leptin increased in O versus N mares. O mares were also more insulin resistant than N mares with a higher glucose effectiveness. Postnatally, there was no difference in offspring growth between groups. Nevertheless, plasma SAA concentrations were increased in O versus N foals until 6 months, with O foals being consistently more insulin resistant with a higher glucose effectiveness. At 12 months of age, O foals were significantly more affected by osteochondrosis than N foals. All other parameters were not different between groups. CONCLUSION In conclusion, maternal obesity altered metabolism and increased low-grade inflammation in both dams and foals. The risk of developing osteochondrosis at 12 months of age was also higher in foals born to obese dams.

Abstract
Harmonic mode ultrasound with injection of a contrast enhancement agent allows visualization of mobile microbubbles in the carotid plaque corresponding to neovessels secondary to an inflammation or hypoxia. These neovessels could be considered "precursor" markers of the vulnerable plaque. The aim of this work was to give an update on ultrasound contrast imaging acquisition in the exploration of carotid artery both for atheromatous lesions and for large vessel vasculitis. A precise description of the material to be used, the image acquisition methodology and the environmental conditions is discussed, emphasizing the pitfalls to be avoided as well as proper image interpretation. Microbubbles in a plaque are significantly associated with an increase in cardiovascular events (infarction and acute coronary syndrome) and ipsilateral cerebral ischemic events. Wall irregularities, microfissures and ulcer plaque detection are facilitated by the use of contrast compared to the CT scan. No studies have yet validated contrast enhanced ultrasound in the exploration of asymptomatic carotid stenosis. Contrast enhanced ultrasound also allows to detect vasculitis of the large vessels active phases by the presence of microbubbles in the carotid wall thickening and to monitor the regression under appropriate medical treatment. Future validation studies or even registries are needed to allow better use of this tool in everyday clinical practice.

Abstract
INTRODUCTION Schizophrenia causes psychological difficulties (with positive and/or negative symptoms) as well as cognitive disabilities (attention, memory, executive functions and social cognition). Moreover, 40 to 60% of patients suffer from an excess of weight or obesity (due to bad eating habits, eating disorders or medication). All these difficulties impair their autonomy and their insertion into the society. In this context, setting-up a therapeutic tool, which may have cognitive benefits seems relevant. Thus, MODen is a therapeutic educational tool whose aim is to improve cognitive functions and the symptoms by using "nutritional balance" as an aid. METHOD In this treatment program, two therapists lead a group of 5 to 8 patients which group meets once a week during two to four hours for 16 weeks, divided in 4 cycles. The first three weeks of each cycle consists of theoretical instruction: patients talk about their eating habits, information is given about nutritional balance and preparation of meals. In the different cycles, flexibility, planning, memory and attention are trained. For instance, the work on categorisation of foods and nutritional balance allow enhancing flexibility abilities. Writing down the lists of different ingredients needed for one week's meals and preparation of meals train planning abilities. MODen also takes into account ecological issues such as the limited budget of patients to do their shopping (this budget is around 4 euros per meal in France). The budget is also linked to planning abilities and reasoning. Finally, during the last session of each cycle the group prepares a meal (from the shopping to cooking). This last session is all about sharing and social cognition abilities. By the end of the program, patients will have prepared four meals together. Also "homework" has to be done each week in order to facilitate memorisation of what has been learned during the last session and to prepare the beginning of the next session. RESULTS In a pilot study with 8 patients with schizophrenia (DSM-IV), improvements in PANSS negative symptoms and disorganization (respectively P<0.02; P<0.02) were observed. An underlying improvement at BECS scores was also observed (P<0.08). Regarding those preliminary results as well as the ecological qualities of this program, this therapeutic tool could be relevant in the treatment of patients with schizophrenia.

Abstract
The Optic atrophy 1 protein (OPA1) is a key element in the dynamics and morphology of mitochondria. We demonstrated that the absence of IκB kinase-α, which is a key element of the nonclassical NF-κB pathway, has an impact on the mitochondrial network morphology and OPA1 expression. In contrast, the absence of NF-κB essential modulator (NEMO) or IκB kinase-β, both of which are essential for the canonical NF-κB pathway, has no impact on mitochondrial dynamics. Whereas Parkin has been reported to positively regulate the expression of OPA1 through NEMO, herein we found that PARK2 overexpression did not modify the expression of OPA1. PARK2 expression reduced the levels of Bax, and it prevented stress-induced cell death only in Bak-deficient mouse embryonic fibroblast cells. Collectively, our results point out a role of the nonclassical NF-κB pathway in the regulation of mitochondrial dynamics and OPA1 expression.

Abstract
Despite an increasingly vast literature on cophylogenetic reconstructions for studying host–parasite associations, understanding the common evolutionary history of such systems remains a problem that is far from being solved. Most algorithms for host–parasite reconciliation use an event-based model, where the events include in general (a subset of) cospeciation, duplication, loss, and host switch. All known parsimonious event-based methods then assign a cost to each type of event in order to find a reconstruction of minimum cost. The main problem with this approach is that the cost of the events strongly influences the reconciliation obtained. Some earlier approaches attempt to avoid this problem by finding a Pareto set of solutions and hence by considering event costs under some minimization constraints. To deal with this problem, we developed an algorithm, called Coala, for estimating the frequency of the events based on an approximate Bayesian computation approach. The benefits of this method are 2-fold: (i) it provides more confidence in the set of costs to be used in a reconciliation, and (ii) it allows estimation of the frequency of the events in cases where the data set consists of trees with a large number of taxa. We evaluate our method on simulated and on biological data sets. We show that in both cases, for the same pair of host and parasite trees, different sets of frequencies for the events lead to equally probable solutions. Moreover, often these solutions differ greatly in terms of the number of inferred events. It appears crucial to take this into account before attempting any further biological interpretation of such reconciliations. More generally, we also show that the set of frequencies can vary widely depending on the input host and parasite trees. Indiscriminately applying a standard vector of costs may thus not be a good strategy.

Abstract
Plusieurs études montrent l’intérêt des programmes de remédiation cognitive et de psychoéducation dans la prise en charge des patients souffrant de schizophrénie dans le cadre de soins de réhabilitation psycho-sociale [1]. Ces programmes dispensés de façon isolée sont moins efficaces que ceux effectués dans une démarche de soins intégrative [2,3] et en impliquant l’ensemble des acteurs de soins et de réhabilitation (sanitaire, MDPH, médico-social, milieu professionnel). Depuis 2009, le centre intersectoriel Crisalid (pôle FJ5, CHI de Clermont de l’Oise, Picardie) propose un programme intégratif et personnalisé, appelé COMBIMOD (combinaison de modules de remédiation cognitive et d’éducation thérapeutique) destiné aux personnes souffrant de schizophrénie et à leurs proches habitant dans l’Oise, suivi par le sanitaire, le privé et le médico-social. Ce programme combine des modules de remédiation cognitive francophones validés à des modules d’éducation thérapeutique spécifiques construits autour des déficits cognitifs. L’objectif de ce poster est :– de décrire au travers du parcours de soins de 3 personnes souffrant de schizophrénie la mise en place du programme COMBIMOD (de l’importance de : l’entretien motivationnel, l’évaluation globale [clinique, thérapeutique, neurocognitive, cognition sociale, fonctionnelle], la restitution du bilan, la mise en place d’un programme personnalisé et intégratif) jusqu’à la réalisation des objectifs professionnels ;– montrer l’importance de l’articulation entre le sanitaire, le privé, le médico-social et le milieu professionnel.Au terme du programme et grâce à un travail d’articulation entre le sanitaire (secteur : CMP, hôpital de jour, CATTP), la MDPH, le médico-social (centre de réadaptation professionnelle et de formation, ESAT de transition) les 3 patients se sont réinsérer professionnellement en milieu ordinaire.

Abstract
The striking excess of affected males in autism spectrum disorders (ASD) suggests that genes located on chromosome X contribute to the etiology of these disorders. To identify new X-linked genes associated with ASD, we analyzed the entire chromosome X exome by next-generation sequencing in 12 unrelated families with two affected males. Thirty-six possibly deleterious variants in 33 candidate genes were found, including PHF8 and HUWE1, previously implicated in intellectual disability (ID). A nonsense mutation in TMLHE, which encodes the ɛ-N-trimethyllysine hydroxylase catalyzing the first step of carnitine biosynthesis, was identified in two brothers with autism and ID. By screening the TMLHE coding sequence in 501 male patients with ASD, we identified two additional missense substitutions not found in controls and not reported in databases. Functional analyses confirmed that the mutations were associated with a loss-of-function and led to an increase in trimethyllysine, the precursor of carnitine biosynthesis, in the plasma of patients. This study supports the hypothesis that rare variants on the X chromosome are involved in the etiology of ASD and contribute to the sex-ratio disequilibrium.

Abstract
Diagnosis of superficial vascular anomalies, previously called "angiomas", is basically clinical. Ultrasound and duplex Doppler imaging is a simple and helpful tool to confirm the clinical diagnosis and/or to suggest further required imaging modalities. The purpose of this work is to demonstrate the usefulness of duplex Doppler and ultrasound for exploring vessel and soft tissue components of vascular anomalies.

AIM To evaluate contrast-enhanced ultrasound (CEUS) as an effective alternative to CT-angiography (CTA) for endoleak detection and aneurismal sac diameter measurement in the follow-up after endovascular abdominal aortic aneurysm repair (EVAR). METHODS From January 2006 to December 2010, 395 patients underwent EVAR follow-up with both CTA and CEUS. The diameter of the aneurismal sac and the presence of endoleaks were evaluated in all the 395 paired examinations. RESULTS Bland-Altman plots showed a good agreement in aneurismal sac diameter evaluation between the two imaging modalities. The mean diameter was 54.93 mm (standard deviation (SD) ±12.57) with CEUS and 56.01 mm (SD ± 13.23) with CTA. The mean difference in aneurismal sac diameter was -1.08 mm ± 3.3543 (95% confidence interval (CI), -0.75 to -1.41), in favour of CTA. The number of observed agreement in endoleak detection was 359/395 (90.89%). The two modalities detected the same type I and type III endoleaks. McNemar's χ(2) test confirmed that CTA and CEUS are equivalent in endoleak detection. CONCLUSIONS CEUS demonstrated to be as accurate as CTA in endoleak detection and abdominal aortic aneurysm diameter measurements during EVAR follow-up, without carrying the risks of radiation exposure or nephrotoxicity. Even if it cannot be proposed as the sole imaging modality during follow-up, our analysis suggests that it should have a major role.

Abstract
Abstract
Aims: To determine the molecular subtypes existing in a retrospective series of classical lobular carcinoma in situ (LCIS) and to evaluate the risk of relapse in the different groups. To assess by immunohistochemistry the expression of stem cell markers in LCIS.
Material and methods: A series of 58 LCIS have been retrospectively selected in our files according to the availability of clinical data. The expression of E-cadherin (clone 4A2C7, Invitrogen), ER (clone 6F11, Novocastra), PR (clone 1A6, Novocastra), ERBB2 (clone CB11, Novocastra), EGFR (clone 31G7, Zymed), KI67 (MIB1), CD44 (1563C11, Thermo Fisher Scientific), CD24 (clone SN3b, Thermo Fisher Scientific) and ALDH1 (clone 44/ALDH, BD transduction Laboratories) were determined on whole tissue sections for 47 patients with available paraffin blocks. For ER, PR, EGFR and Ki67, 10% of positive cells were used as cut-off. For ERBB2, the interpretation was performed according to the ASCO guidelines for invasive carcinomas. The molecular subtypes were defined as luminal A: ER+ ERBB2- and Ki67<10%; luminal B: ER+, Ki67 >10% or ERBB2+; ERBB2 ER-and ERBB2 3+; basal-like: ER-PR-ERBB2-and EGFR+. All patients’ charters were reviewed and clinical data was recorded. All of the patients underwent tumorectomy without any radiation therapy.
Results: Median age was 50 yrs (min 31; max 72). The majority of the lesions were diagnosed by microcalcifications on mammography (62% of the cases) and treated by lumpectomy (98%). The majority of the lesions were classical LCIS (97%). The majority of the cases were E-cadherin negative (53%), the other cases presenting a weak staining of 10 to 80% of the cells, ER +ve (91%), PR +ve (68%), ERBB2 -ve (100%), KI67 low (81%), EGFR-ve (89%). A total of 33 cases were defined as luminal A (72%), 9 cases as luminal B (20%) and 4 cases were ER-ve/ERBB2-ve. At five years, all patients were alive, 1/33 luminal A experienced a relapse contrasting with 4 out of 9 luminal B (1 LCIS, 3 invasive carcinomas including 2 ductal and 1 lobular) (p= 0.004). The majority of the cases was CD44 +ve (93%), CD24 -ve (57%) and ALDH1 -ve (74%). No statistically significant link was observed between the stem cell phenotype defined as CD44+/CD24-/ALDH1+ and a risk of relapse.
Conclusions: Classical LCIS are in majority of luminal A type (72%). 20% of LCIS are luminal B and present a risk of relapse higher than luminal A LCIS. In this retrospective pilot study, for the first time to our knowledge, we observed a higher risk of relapse associated with the luminal B phenotype of LCIS. This observation needs to be confirmed in a larger series but could contribute to improve the clinical management of classical LCIS patients.

Abstract
Abstract
Purpose: The aim of this retrospective, mono-centric, study was to assess the benefit of breast surgery for inflammatory breast cancer (IBC).Patients and methods:From January 1st 1985 and December 31st 1999; out of 13180 patients diagnosed at the Institut Curie with non metastatic breast cancer, 280 (2%) were treated with curative intent for IBC with primary chemotherapy followed by either exclusive radiotherapy (118 patients, 51%) or surgery with or without radiotherapy (114 patients, 49%). Median follow-up of 11 years.Results:The two groups were comparable apart from a higher rate of tumors smaller than 70mm (43% vs 33%, p=0.003), a higher rate of clinical stage N2 (15% vs 5%, p=0.04) and fewer histopathologic grade 3 tumors (46% vs 61%, p<0.05) in the no-surgery group.The addition of surgery was associated with a significant improvement in locoregional disease control (p=0.04). At 5 years locoregional free interval was 79% in the surgery group vs 66 % in the exclusive radiotherapy group and at 10 years: 78 % vs 59 % respectively.In the univariate analysis, in addition to the absence of surgery (p=0.04), other prognostic factors associated with higher locoregional recurrence rates were: high clinical nodal stage (p=0.009), high histological nodal status (p=0.02) and the absence of taxanes in the neoadjuvant chemotherapy regimen (p=0.02). In the multivariate analysis, only the clinical N2 stage was associated with a higher rate of locoregional recurrences. There were no significant difference in overall survival (52% at 5 years, 38% at 10 years, p=0.32) or disease-free interval (at 5 years 32%, at 10 years 6%,p=0.35).Factors associated in univariate analyses with a decreased overall survival were age over 50 years, the absence of achievement of a clinical response ≥ 50%, absence of hormone receptors and the absence of taxanes in the neoadjuvant chemotherapy regimen.In multivariate analysis, only the absence of hormone receptors and either complete or partial clinical tumor response remained significant.Factors associated in univariate analyses with a higher rate of disease recurrences were the absence of achievement of a clinical response ≥ 50%, absence of hormone receptors and the absence of taxanes in the neoadjuvant chemotherapy regimen.In multivariate analysis, only the absence of hormone receptors and of clinical tumor response remained significant. Late toxicities were not significantly different between the two treatment groups except for a higher rate of fibrosis in the no-surgery group (p<0.0001), and more lymphedema in the surgery group (p=0.002).Conclusion:This study seems to confirm that the addition of breast surgery to radiotherapy should contribute to increase local control after induction chemotherapy. IBC, despite combined modality treatment, continues to suffer from dismal prognosis and efforts must be made to improve overall survival.

Abstract
Abstract
Purpose: To determine whether exclusive radiotherapy (ERT) could be an option after complete clinical response (cCR) to neoadjuvant chemotherapy (NCT) for early breast cancers (EBC).Patients and methods: Between 1985 and 1999, 1477 patients received NCT for EBC considered to be too large for primary conservative surgery. Of 165 patients with cCR, 65 were treated by breast surgery (with radiotherapy) and 100 by ERT.Results: The two groups were comparable in terms of baseline characteristics, except for larger initial tumor sizes in the ERT group. There were no significant differences in overall, disease-free and metastasis-free survivals. Five-year and 10-year overall survivals were 91% and 77% in the no surgery group and 82% and 79% in the surgery group, respectively (p = 0.9). However, a non-significant trend towards higher locoregional recurrence rates (LRR) was observed in the no surgery group (31% vs. 17% at 10 years; p = 0.06). In patients with complete responses on mammography and/or ultrasound, LRR were not significantly different (p = 0.45, 10-year LRR: 21% in surgery vs. 26% in ERT). No significant differences were observed in terms of the rate of cutaneous, cardiac or pulmonary toxicities.Conclusion: Omission of breast surgery in patients who achieved cCR to NCT was not associated with an increased risk of distant metastases or death. However a trend towards an increased risk of locoregional recurrence was observed in the ERT group. Imaging modalities appear to be essential to monitor chemotherapy response and possibly select patients in whom ERT can be proposed.

Abstract
Large collections of protein-encoding open reading frames (ORFs) established in a versatile recombination-based cloning system have been instrumental to study protein functions in high-throughput assays. Such ‘ORFeome’ resources have been developed for several organisms but in virology, plasmid collections covering a significant fraction of the virosphere are still needed. In this perspective, we present ViralORFeome 1.0 (http://www.viralorfeome.com), an open-access database and management system that provides an integrated set of bioinformatic tools to clone viral ORFs in the Gateway® system. ViralORFeome provides a convenient interface to navigate through virus genome sequences, to design ORF-specific cloning primers, to validate the sequence of generated constructs and to browse established collections of virus ORFs. Most importantly, ViralORFeome has been designed to manage all possible variants or mutants of a given ORF so that the cloning procedure can be applied to any emerging virus strain. A subset of plasmid constructs generated with ViralORFeome platform has been tested with success for heterologous protein expression in different expression systems at proteome scale. ViralORFeome should provide our community with a framework to establish a large collection of virus ORF clones, an instrumental resource to determine functions, activities and binding partners of viral proteins.

Abstract
INTRODUCTION The cancer of the cervix annually occurs in 150 women in Brittany in the absence of organized screening. MATERIAL AND METHODS Retrospective study concerning 191 patients treated for an invasive cancer of the uterine cervix between 2000 and 2005 analyzing their cytological past. The average age of the patients was 52 years (22-87 years). The socioeconomic level of the patients was recorded. The distribution of under histological types was: squamous, 73% (54 years average age) and adenocarcinoma, 22% (average age 47 years). All the stages were represented: stage I 46%, II 32%, III 9% and stage IV 13%. RESULTS Cancer was symptomatic in 89% of the cases and 72% of the patients had not profited from cytological screening according to French recommendations (50% no follow-up, 22% follow-up between three and 10 years), while 28% of the patients had a smear in the three years. The socioeconomic level of the patients strongly influenced the participation in screening. The proportion of patients having an invasive adenocarcinom was 31% in the patients with a smear going back to less than three years (versus 22% in our total population) and this histological subtype was mainly represented in patients less than 35 years old (35%). Lastly, 2,6% of the patients were lost after realization of a pathological smear. CONCLUSION The extension of screening and its organization remain a priority in our area. The average sensitivity of the smear is illustrated by the on-representation of the adenocarcinoma, in particular among young women.
