Abstract
BACKGROUND Biallelic pathogenic variants in SLC5A6 resulting in sodium-dependent multivitamin transporter (SMVT) defect have recently been described as a vitamin-responsive inborn error of metabolism mimicking biotinidase deficiency. To our knowledge, only 16 patients have been reported so far with various clinical phenotypes such as neuropathy and other neurologic impairments, gastro-intestinal dysfunction and failure to thrive, osteopenia, immunodeficiency, metabolic acidosis, hypoglycemia, and recently severe cardiac symptoms. METHODS We describe a case report of a 5-month-old girl presenting two recurrent episodes of metabolic decompensation and massive cardiac failure in the course of an infectious disease. We compare clinical, biological, and genetic findings of this patient to previous literature collected from Pubmed database (keywords: Sodium-dependent multivitamin transporter (SMVT), SMVT defect/disorder/deficiency, SLC5A6 gene/mutation). RESULTS We highlight the life-threatening presentation of this disease, the stagnation of psychomotor development, the severe and persistent hypogammaglobulinemia, and additionally, the successful clinical response on early vitamin supplementation (biotin 15 mg a day and pantothenic acid 100 mg a day). Metabolic assessment showed a persistent increase of urinary 3-hydroxyisovaleric acid (3-HIA) as previously reported in this disease in literature. CONCLUSION SMVT deficiency is a vitamin-responsive inborn error of metabolism that can lead to a wide range of symptoms. Increased and isolated excretion of urinary 3-hydroxyisovaleric acid may suggest, in the absence of markedly reduced biotinidase activity, a SMVT deficiency. Prompt supplementation with high doses of biotin and pantothenic acid should be initiated while awaiting results of SLC5A6 sequencing as this condition may be life-threatening.

Abstract
SETTING Health measures taken during the pandemic deeply modified the clinical research practices. At the same time, the demand for the results of the COVID-19 trials was urgent. Thus, the objective of this article is to share Inserm's experience in ensuring quality control in clinical trials in this challenging context. OBJECTIVES DisCoVeRy is a phase III randomized study that aimed at evaluating the safety and efficacy of 4 therapeutic strategies in hospitalized COVID-19 adult patients. Between March, 22nd 2020 and January, 20th 2021, 1309 patients were included. In order to guarantee the best quality of data, the Sponsor had to adapt to the current sanitary measures and to their impact on clinical research activity, notably by adapting Monitoring Plan objectives, involving the research departments of the participating hospitals and a network of clinical research assistants (CRAs). RESULTS Overall, 97 CRAs were involved and performed 909 monitoring visits. The monitoring of 100% of critical data for all patients included in the analysis was achieved, and despite of the pandemic context, a conform consent was recovered for more than 99% of patients. Results of the study were published in May and September 2021. DISCUSSION/CONCLUSION The main monitoring objective was met thanks to the mobilization of considerable personnel resources, within a very tight time frame and external hurdles. There is a need for further reflection to adapt the lessons learned from this experience to the context of routine practice and to improve the response of French academic research during a future epidemic.

Abstract
The current COVID-19 pandemic was an exceptional health situation, including for drug use. As there was no known effective drug for COVID-19 at the beginning of the pandemic, different drug candidates were proposed. In this article, we present the challenges for an academic Safety Department to manage the global safety of a European trial during the pandemic. The National Institute for Health and Medical Research (Inserm) conducted a European multicenter, open-label, randomized, controlled trial involving three repurposed and one-in development drugs (lopinavir/ritonavir, IFN-β1a, hydroxychloroquine, and remdesivir) in adults hospitalized with COVID-19. From 25 March 2020 to 29 May 2020, the Inserm Safety Department had to manage 585 Serious Adverse Events (SAEs) initial notification and 396 follow-up reports. The Inserm Safety Department's staff was mobilized to manage these SAEs and to report Expedited safety reports to the competent authorities within the legal timeframes. More than 500 queries were sent to the investigators due to a lack of or incoherent information on SAE forms. At the same time, the investigators were overwhelmed by the management of patients suffering from COVID-19 infection. These particular conditions of missing data and lack of accurate description of adverse events made evaluation of the SAEs very difficult, particularly the assessment of the causal role of each investigational medicinal product. In parallel, working difficulties were accentuated by the national lockdown, frequent IT tool dysfunctions, delayed implementation of monitoring and the absence of automatic alerts for SAE form modification. Although COVID-19 is a confounding factor per se, the delay in and quality of SAE form completion and the real-time medical analysis by the Inserm Safety Department were major issues in the quick identification of potential safety signals. To conduct a high-quality clinical trial and ensure patient safety, all stakeholders must take their roles and responsibilities.

Abstract
Setting-up a high quality, compliant and efficient pharmacovigilance (PV) system in multi-country clinical trials can be more challenging for academic sponsors than for companies. To ensure the safety of all participants in academic studies and that the PV system fulfils all regulations, we set up a centralized PV system that allows sponsors to delegate work on PV. This initiative was put in practice by our Inserm-ANRS MIE PV department in two distinct multinational European consortia with 19 participating countries: conect4children (c4c) for paediatrics research and EU-Response for Covid-19 platform trials. The centralized PV system consists of some key procedures to harmonize the complex safety processes, creation of a local safety officer (LSO) network and centralization of all safety activities. The key procedures described the safety management plan for each trial and how tasks were shared and delegated between all stakeholders. Processing of serious adverse events (SAEs) in a unique database guaranteed the full control of the safety data and continuous evaluation of the risk-benefit ratio. The LSO network participated in efficient regulatory compliance across multiple countries. In total, there were 1312 SAEs in EU-Response and 83 SAEs in c4c in the four trials. We present here the lessons learnt from our experience in four clinical trials. We managed heterogeneous European local requirements and implemented efficient communication with all trial teams. Our approach builds capacity for PV that can be used by multiple academic sponsors.

Abstract
Methicillin-resistant Staphylococcus aureus (MRSA) is a bacterial pathogen responsible for significant human morbidity and mortality. Post-transcriptional regulation by small RNAs (sRNAs) has emerged as an important mechanism for controlling virulence. However, the functionality of the majority of sRNAs during infection is unknown. To address this, we performed UV cross-linking, ligation, and sequencing of hybrids (CLASH) in MRSA to identify sRNA-RNA interactions under conditions that mimic the host environment. Using a double-stranded endoribonuclease III as bait, we uncovered hundreds of novel sRNA-RNA pairs. Strikingly, our results suggest that the production of small membrane-permeabilizing toxins is under extensive sRNA-mediated regulation and that their expression is intimately connected to metabolism. Additionally, we also uncover an sRNA sponging interaction between RsaE and RsaI. Taken together, we present a comprehensive analysis of sRNA-target interactions in MRSA and provide details on how these contribute to the control of virulence in response to changes in metabolism.

Abstract
Introduction Les mesures sanitaires mises en place pendant la pandémie, telles que la distanciation sociale et les confinements, ont profondément modifié les pratiques de recherche clinique en restreignant l'accès aux participants en raison des risques de contamination, et en limitant la disponibilité du personnel des sites en raison de la surcharge de travail. Dans le même temps, la demande de résultats issus des essais COVID-19 était urgente et soumise à la pression de la communauté scientifique, de la société civile et des médias. Ainsi, l'objectif de cette communication est de partager l'expérience de l'Inserm pour assurer le contrôle qualité d'un essai clinique dans ce contexte particulier. Methodes DisCoVeRy est une étude de phase III adaptative et randomisée qui visait, dans sa première phase, à évaluer la sécurité et l'efficacité de 4 stratégies thérapeutiques chez des patients adultes hospitalisés pour COVID-19 ayant un besoin de supplémentation en oxygène. Entre le 22 mars 2020 et le 20 janvier 2021, 1176 patients ont été inclus en France. Afin de garantir la qualité des données recueillies, le promoteur a dû s'adapter aux mesures sanitaires en vigueur et à leur impact sur l'activité de recherche clinique. Il s'agissait notamment : d'adapter les objectifs du Plan de Monitoring (vérification des données sources pour 100% des données critiques de tous les participants), d'impliquer les Direction de la Recherche et de l'Innovation (DRI) des hôpitaux participants, de solliciter un réseau d'assistants de recherche clinique (ARC) et des personnels Inserm. Resultats Au total, 91 ARCs ont été impliqués en France et ont effectué 834 visites de monitoring du 24 avril 2020 au 15 octobre 2021, donnant lieu à 539 rapports de monitoring. Parmi les 1176 patients inclus et randomisés, un consentement a été obtenu permettant l'analyse de toutes les données chez 1112 (94,6%), des données jusqu'à la levée de la sédation chez 23 (1,9%), des données jusqu'au retrait du consentement ou à la décision de l'investigateur principal chez 32 (2,7%). Neuf (0,8%) patients n'ont pu être analysés en l'absence de consentement conforme. Le contrôle de 100% des données critiques pour tous les patients inclus dans l'analyse a été réalisé, conformément au Plan de Monitoring. Les résultats de l'étude ont été publiés en mai et septembre 2021. Au regard de l'importance de rendre les résultats publics, ces premières publications ont été soumises sans que toutes les données critiques aient été contrôlées. Le monitoring du consentement, des critères de sélection et du critère d'évaluation principal avait été priorisé afin d'assurer la fiabilité des résultats sur ces éléments majeurs. Conclusion Malgré le démarrage contraint de l'étude avant la mise en place de l'équipe de monitoring, le rythme d'inclusion très élevé, et les contraintes majeures liées au contexte pandémique, l'ensemble des données critiques selon le Plan de Monitoring initial a été monitoré en seulement 18 mois. Ce résultat est notamment dû à la mobilisation de ressources en personnel considérables, dans un délai très court. Cependant, la mise en place d'une telle organisation souligne l'importance de disposer d'indicateurs faciles à consulter en temps réel pour aider au pilotage de l'étude et à la planification de l'utilisation de la base de données et de la publication des résultats.

Abstract
BACKGROUND Soft-tissue sarcomas (STS) represent a heterogeneous group of rare tumors including more than 70 different histological subtypes. High throughput molecular analysis (next generation sequencing exome [NGS]) is a unique opportunity to identify driver mutations that can change the usual one-size-fits-all treatment paradigm to a patient-driven therapeutic strategy. The primary objective of the MULTISARC trial is to assess whether NGS can be conducted for a large proportion of metastatic STS participants within a reasonable time, and, secondarily to determine whether a NGS-guided therapeutic strategy improves participant's outcome. METHODS This is a randomized, multicentre, phase II/III trial inspired by the design of umbrella and biomarker-driven trials. The setting plans up to 17 investigational centres across France and the recruitment of 960 participants. Participants aged at least 18 years, with unresectable locally advanced and/or metastatic STS confirmed by the French sarcoma pathological reference network, are randomized according to 1:1 allocation ratio between the experimental arm "NGS" and the standard "No NGS". NGS will be considered feasible if (i) NGS results are available and interpretable, and (ii) a report of exome sequencing including a clinical recommendation from a multidisciplinary tumor board is provided to investigators within 7 weeks from reception of the samples on the biopathological platform. A feasibility rate of more than 70% is expected (null hypothesis: 70% versus alternative hypothesis: 80%). In terms of care, participants randomized in "No NGS" arm and who fail treatment will be able to switch to the NGS arm at the request of the investigator. DISCUSSION The MULTISARC trial is a prospective study designed to provide high-level evidence to support the implementation of NGS in routine clinical practice for advanced STS participants, on a large scale.

Abstract
The success of the major opportunistic human Staphylococcus aureus relies on the production of numerous virulence factors, which allow rapid colonization and dissemination in any tissues. Indeed, regulation of its virulence is multifactorial, and based on the production of transcriptional factors, two-component systems (TCS) and small regulatory RNAs (sRNAs). Advances in high-throughput sequencing technologies have unveiled the existence of hundreds of potential RNAs with regulatory functions, but only a fraction of which have been validated in vivo. These discoveries have modified our thinking and understanding of bacterial physiology and virulence fitness by placing sRNAs, alongside transcriptional regulators, at the center of complex and intertwined regulatory networks that allow S. aureus to rapidly adapt to the environmental cues present at infection sites. In this review, we describe the recently acquired knowledge of characterized regulatory RNAs in S. aureus that are associated with metal starvation, nutrient availability, stress responses and virulence. These findings highlight the importance of sRNAs for the comprehension of S. aureus infection processes while raising questions about the interplay between these key regulators and the pathways they control.

Abstract
Objectives We evaluated the clinical, virological and safety outcomes of lopinavir/ritonavir, lopinavir/ritonavir–interferon (IFN)-β-1a, hydroxychloroquine or remdesivir in comparison to standard of care (control) in coronavirus 2019 disease (COVID-19) inpatients requiring oxygen and/or ventilatory support. Methods We conducted a phase III multicentre, open-label, randomized 1:1:1:1:1, adaptive, controlled trial (DisCoVeRy), an add-on to the Solidarity trial (NCT04315948, EudraCT2020-000936-23). The primary outcome was the clinical status at day 15, measured by the WHO seven-point ordinal scale. Secondary outcomes included quantification of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in respiratory specimens and pharmacokinetic and safety analyses. We report the results for the lopinavir/ritonavir-containing arms and for the hydroxychloroquine arm, trials of which were stopped prematurely. Results The intention-to-treat population included 583 participants—lopinavir/ritonavir (n = 145), lopinavir/ritonavir–IFN–β-1a (n = 145), hydroxychloroquine (n = 145), control (n = 148)—among whom 418 (71.7%) were male, the median age was 63 years (IQR 54–71), and 211 (36.2%) had a severe disease. The day-15 clinical status was not improved with the investigational treatments: lopinavir/ritonavir versus control, adjusted odds ratio (aOR) 0.83, (95% confidence interval (CI) 0.55–1.26, p 0.39), lopinavir/ritonavir–IFN–β-1a versus control, aOR 0.69 (95%CI 0.45–1.04, p 0.08), and hydroxychloroquine versus control, aOR 0.93 (95%CI 0.62–1.41, p 0.75). No significant effect of investigational treatment was observed on SARS-CoV-2 clearance. Trough plasma concentrations of lopinavir and ritonavir were higher than those expected, while those of hydroxychloroquine were those expected with the dosing regimen. The occurrence of serious adverse events was significantly higher in participants allocated to the lopinavir/ritonavir-containing arms. Conclusion In adults hospitalized for COVID-19, lopinavir/ritonavir, lopinavir/ritonavir–IFN–β-1a and hydroxychloroquine improved neither the clinical status at day 15 nor SARS-CoV-2 clearance in respiratory tract specimens.

Abstract
Although small regulatory RNAs (sRNAs) are widespread among the bacterial domain of life, the functions of many of them remain poorly characterized notably due to the difficulty of identifying their mRNA targets. Here, we described a modified protocol of the MS2-Affinity Purification coupled with RNA Sequencing (MAPS) technology, aiming to reveal all RNA partners of a specific sRNA in vivo. Broadly, the MS2 aptamer is fused to the 5' extremity of the sRNA of interest. This construct is then expressed in vivo, allowing the MS2-sRNA to interact with its cellular partners. After bacterial harvesting, cells are mechanically lysed. The crude extract is loaded into an amylose-based chromatography column previously coated with the MS2 protein fused to the maltose binding protein. This enables the specific capture of MS2-sRNA and interacting RNAs. After elution, co-purified RNAs are identified by high-throughput RNA sequencing and subsequent bioinformatic analysis. The following protocol has been implemented in the Gram-positive human pathogen Staphylococcus aureus and is, in principle, transposable to any Gram-positive bacteria. To sum up, MAPS technology constitutes an efficient method to deeply explore the regulatory network of a particular sRNA, offering a snapshot of its whole targetome. However, it is important to keep in mind that putative targets identified by MAPS still need to be validated by complementary experimental approaches.

Abstract
BACKGROUND Updated WHO guidelines recommend a dolutegravir-based regimen as the preferred first-line treatment for HIV infection and low-dose efavirenz (400 mg) as an alternative. We aimed to report the non-inferior efficacy of dolutegravir compared with efavirenz 400 mg at week 96. METHODS We did a multicentre, randomised, open label, phase 3 trial in in three hospitals in Yaoundé, Cameroon, in HIV-1 infected antiretroviral-naive adults with an HIV RNA viral load of greater than 1000 copies per mL to compare dolutegravir 50 mg with efavirenz 400 mg (reference treatment), both combined with lamivudine and tenofovir disoproxil fumarate. The primary endpoint was the proportion with a viral load of less than 50 copies per mL at week 48 (10% non-inferiority margin). The study is registered with ClinicalTrials.gov, NCT02777229 and is ongoing. FINDINGS Between July, 2016, and August, 2019, of 820 patients assessed, 613 were randomly assigned to receive at least one dose of study medication, with 310 in the dolutegravir group and 303 in the efavirenz 400 mg group. At week 96 in the intention-to-treat analysis, 229 (74%) of 310 patients receiving dolutegravir and 219 (72%) of 303 patients receiving efavirenz, achieved plasma HIV-1 RNA less than 50 copies per mL (difference 1·6%, 95% CI -5·4 to 8·6; p=0.66). Viral load suppression was reached significantly more rapidly in the dolutegravir group (p<0·001). Virological failure (>1000 copies per mL) was observed in 27 patients (eight in the dolutegravir group, among which, three women switched to efavirenz 600 mg because of the dolutegravir teratogeneicity signal, and 19 in the efavirenz 400 mg group). No acquired resistance mutations to dolutegravir were observed against 17 mutations to efavirenz with or without mutations to lamivudine and tenofovir disoproxil fumarate among the 19 efavirenz 400 mg participants with virological failure. Weight gain was greater in the dolutegravir group (median weight gain, 5·0 kg in the dolutegravir group and 3·0 kg in the efavirenz 400 mg group, p<0·001, and incidence of obesity, 22% in the dolutegravir group and 16% in the efavirenz 400 mg group, p=0·043). The incidence of new WHO HIV-related stage 3 and 4 events was similar in each group (12 [4%] in each group). The two groups had similar rates of serious adverse events (28 [9%] of 310 in the dolutegravir group and 21 [7%] of 303 in the efavirenz 400 mg group). 18 deaths were observed during the 96-week follow-up (eight in the dolutegravir group and ten in the efavirenz 400 mg group). INTERPRETATION The non-inferior efficacy of the dolutegravir-based regimen and non-emergence of dolutegravir resistance at 96 weeks supports its use as a first-line regimen for antiretroviral-naive adults with HIV-1 infection. Viral load suppression was reached more quickly in the dolutegravir group and weight gain was significantly higher. FUNDING UNITAID and the French National Agency for AIDS Research.

Abstract
Training and repeated exposure to odorants leads to enhanced olfactory sensitivity. So far, the efficacy of intensive olfactory training on olfactory function in a healthy population and its underlying neurobiological basis remain poorly known. This study investigated the effects of a 6-week intensive and well-controlled olfactory training on olfactory function and brain structure/neuroplasticity. Thirty-six healthy young individuals were recruited and randomly distributed in three groups: (1) 12 participants underwent daily intensive olfactory training of at least 20 min that included an (a) odor intensity classification task, an (b) odor quality classification task and an (c) target odor detection task, (2) 12 participants underwent an equivalent visual control training, and (3) 12 control individuals did not participate in any training. Before and after the training period, all participants performed a series of olfactory tests and those from groups 1 and 2 underwent structural magnetic resonance (MR) imaging, from which we obtained measures such as cortical thickness and tissue density. Participants improved in the respectively trained tasks throughout the 6-weeks training period. Those who underwent olfactory training improved general olfactory function compared to control participants, especially in odor identification, thus showing intramodal transfer. Further, MR imaging analysis revealed that olfactory training led to increased cortical thickness in the right inferior frontal gyrus, the bilateral fusiform gyrus and the right entorhinal cortex. This research shows that intensive olfactory training can generally improve olfactory function and that this improvement is associated with changes in the structure of olfactory processing areas of the brain.

Abstract
INTRODUCTION The study sought to assess the functional results and complications of osteosynthesis using the Lambda(®) plate (Zimmer, Étupes, France) in treating fracture of the distal extremity of the humerus. MATERIALS AND METHODS The initial series comprised 115 patients (116 fractures), treated between 1992 and 2008. Forty-one (mainly foreigners) were lost to follow-up. The final series thus comprised 74 patients (75 fractures): 44 female and 30 male, with a mean age of 46±23 years (range, 16-95 years), 22 (29%) being aged 65 years or over. According to AO classification, 22 of the fractures of the distal extremity of the humerus (29%) were diaphyseal-metaphyseal, corresponding to a particular grade of type A2, 12 (16%) were type A2 or A3, six (8%) type B, and 35 (47%) type C. Eight were open fractures: seven grade 1 and one grade IIa on Gustilo's classification. The Lambda(®) plate is an inverted Y shape, with a stem of up to ten holes and sectile arms that can be remodeled to adapt perfectly to the type of fracture and the shape of the distal end of the humerus. A posterior approach was used in all cases: in 26 cases, an extra-articular transolecranal approach and otherwise a transtricipital approach, either vertical for diaphyseal-metaphyseal fracture or inverted V for type-C fracture. RESULTS Mean follow-up was 115±64 months (range, 24-227 months). There were no cases of infection, non-union of olecranial osteotomy or disassembly of the internal fixation; there was, on the other hand, one case of non-union of the lateral condyle and one of the distal extremity of the humerus, two cases of dysesthesia in the ulnar nerve territory and one in the radial nerve territory (following preoperative paralysis), and four cases of stiffness requiring surgical arthrolysis between 6 and 12 months postoperatively. At follow-up, mean active elbow flexion was 133°±13° (range, 90°-150°) and active extension -12°±14° (range, -45°-0°). Mean elbow flexion range of motion exceeded 100° in 58 patients (77%), was between 50° and 100° in 16 (21%) and was less than 50° in one. Mean Mayo Elbow Performance Score (MEPS) was 97±7 points (range, 40-100), and mean Quick DASH Score (converted as a score out of 100) was 10±18 (range, 0-54). There were 67 excellent results (MEPS, 90-100 points), five good (75-89), two moderate and one poor. The 35 type-C fractures displayed no significant differences from the series as a whole (P=1.24 for MEPS). CONCLUSION Osteosynthesis using the Lambda(®) plate gave excellent medium-term results in terms of both fixation stability and recovery of elbow function after fracture of the distal extremity of the humerus, even in elderly osteoporotic patients. LEVEL OF EVIDENCE Level IV: retrospective study.

Abstract
INTRODUCTION Dislocation is a frequent complication of total hip arthroplasties (THA) especially in older patients, especially when using a posterior approach. In these cases, dual mobility (DM) cups developed by Gilles Bousquet in 1975 can be indicated to reduce this complication risk. HYPOTHESIS Dual mobility cups reduce the rate of dislocation in primary total hip arthroplasty using posterior approach in a single-surgeon series. AIM Test this hypothesis in a controlled study to compare the rate of dislocation in primary total hip arthroplasties done in patients over 50 years old either with a dual mobility cup or a conventional metal-on-polyethylene 28-mm diameter head. PATIENTS AND METHODS Two consecutive series of primary total hip replacements were performed by a single surgeon using a posterolateral approach. The piriformis tendon was left intact. The DM series included 105 patients who underwent arthroplasty between January 2005 and June 2007 with a dual mobility cup (60 women and 45 men, mean age 76.6±5.65 years old [53-93]). The control series (S series) included 108 patients who underwent arthroplasty (56 women and 52 men, mean age 74.2±5.9 years old [53-87]) with a conventional 28-mm polyethylene cup between January 2003 and June 2005. All hip replacements included a 28-mm metal-polyethylene cup and a 12-14-mm Morse taper. Both groups were comparable for gender, diagnosis, body mass index, type of anesthesia and ASA score distribution. All patients included in this series had a minimum follow-up of 1 year. RESULTS There were no dislocations in the DM series and five early dislocations (before the third month) in the S series for a rate of 4.63%. Although the rate of dislocation was higher in the S series (4.63% vs 0%), the difference was barely significant (P=0.0597). DISCUSSION This study comparing the incidence of dislocations after THA with conventional or dual mobility cups, shows that even using a posterior approach and in older patients, dual mobility cups increase stability with no postoperative dislocations. Although results are barely significant, a larger series should confirm the benefit of this implant. In this series, morbidity was not increased with dual mobility cups. LEVEL OF EVIDENCE Level III: retrospective case-control study.

Abstract
A harmonized approach for the validation of analytical methods based on accuracy profile was introduced by a SFSTP commission on the validation of analytical procedure. This fourth and last document aims at illustrating this methodology and the statistics used. Therefore the validation of real case methods are proposed such as methods for the quality control of drugs, for the quantitation of impurities in drug substances, for bioanalysis or for the determination of nutriments. Furthermore, different types of analytical methods are used in order to demonstrate the applicability of the proposed approach to a wide range of methods such as liquid chromatography (LC-UV, LC-MS), spectrophotometry or ELISA.

Abstract
Inhibition of semicarbazide-sensitive amine oxidases (SSAO) and monoamine oxidases (MAO) reduces fat deposition in obese rodents: chronic administration of the SSAO-inhibitor semicarbazide (S) in combination with pargyline (MAO-inhibitor) has been shown to reduce body weight gain in obese Zucker rats, while (E)-2-(4-fluorophenethyl)-3-fluoroallylamine, an SSAO- and MAO-B inhibitor, has been reported to limit weight gain in obese and diabetic mice. Our aim was to state whether such weight gain limitation could occur in non-obese, non-diabetic rats and to extend these observations to other amine oxidase inhibitors. Prolonged treatment of non-obese rats with a high dose of S (900 micromol kg(-1) day(-1)) reduced body weight gain and limited white adipose tissue enlargement. When chronically administered at a threefold lower dose, S also inhibited SSAO activity but not fat depot enlargement, suggesting that effects other than SSAO inhibition were involved in adipose tissue growth retardation. However, combined treatment of this lower dose of S with pargyline inhibited SSAO, MAO, energy intake, weight gain and fat deposition. Adipocytes from treated rats exhibited unchanged insulin responsiveness but impaired antilipolytic responses to amine oxidase substrates. Phenelzine clearly inhibited both MAO and SSAO when tested on adipocytes. Obese rats receiving phenelzine i.p. at 17 micromol kg(-1) day(-1) for 3 weeks, exhibited blunted MAO and SSAO activities in any tested tissue, diminished body weight gain and reduced intra-abdominal adipose tissue. Their adipocytes were less responsive to lipogenesis activation by tyramine or benzylamine. These observations suggest that SSAO inhibition is not sufficient to impair fat deposition. However, combined MAO and SSAO inhibition limits adiposity in non-obese as well as in obese rats.

Anal., in press], a recent SFSTP Commission on the validation of analytical procedure has introduced a harmonized approach for the validation of analytical procedures. In order to complete this guide, the statistical methodology allowing to correctly conclude about the validity of a procedure is proposed in this third part of the guide. Indeed all the steps to obtain the decision tool namely the accuracy profile are described and illustrated step by step by a numerical example. This tool, based on the concept of total error (bias+standard deviation) build with a beta-expectation tolerance interval, allows to easily take the right decision and simultaneously minimizing the risk of the future use of the analytical procedure.

Abstract
As reported in a previous paper, the main objective of the new commission of the Société Française des Sciences et Techniques Pharmaceutiques (SFSTP) was the harmonisation of approaches for the validation of quantitative analytical procedures. In a series of meetings, members of this Commission have first tried to review the objectives of analytical methods and the objectives of validation methods and to recommend the use of two-sided beta-expectation tolerance intervals for total error of validation samples (accuracy profile) in the acceptance/rejection of analytical method in validation phase. In the context of the harmonization, the other objectives were: (i) to propose a consensus on the norms usually recognized, while widely incorporating the ISO terminology; (ii) to recommend to validate the analytical procedure accordingly to the way it will be used in routine; (iii) to elaborate a rational, practical and statistically reliable strategy to assure the quality of the analytical results generated. This strategy has been formalised in a guide and the three latter objectives made by the Commission are summarised in the present paper which is the second part of summary report of the SFSTP commission. The SFSTP guide has been produced to help analysts to validate their analytical methods. It is the result of a consensus between professionals having expertise in analytical and/or statistical fields. The suggestions presented in this paper should therefore help the analyst to design and perform the minimum number validation experiments needed to obtain all the required information to establish and demonstrate the reliability of its analytical procedure.

Abstract
This paper is the first part of a summary report of a new commission of the Société Française des Sciences et Techniques Pharmaceutiques (SFSTP). The main objective of this commission was the harmonization of approaches for the validation of quantitative analytical procedures. Indeed, the principle of the validation of theses procedures is today widely spread in all the domains of activities where measurements are made. Nevertheless, this simple question of acceptability or not of an analytical procedure for a given application, remains incompletely determined in several cases despite the various regulations relating to the good practices (GLP, GMP, ...) and other documents of normative character (ISO, ICH, FDA, ...). There are many official documents describing the criteria of validation to be tested, but they do not propose any experimental protocol and limit themselves most often to the general concepts. For those reasons, two previous SFSTP commissions elaborated validation guides to concretely help the industrial scientists in charge of drug development to apply those regulatory recommendations. If these two first guides widely contributed to the use and progress of analytical validations, they present, nevertheless, weaknesses regarding the conclusions of the performed statistical tests and the decisions to be made with respect to the acceptance limits defined by the use of an analytical procedure. The present paper proposes to review even the bases of the analytical validation for developing harmonized approach, by distinguishing notably the diagnosis rules and the decision rules. This latter rule is based on the use of the accuracy profile, uses the notion of total error and allows to simplify the approach of the validation of an analytical procedure while checking the associated risk to its usage. Thanks to this novel validation approach, it is possible to unambiguously demonstrate the fitness for purpose of a new method as stated in all regulatory documents.

The aim of this study was to perform biometry of the proximal extremity of the radius and to characterize the shape of the radial head. Knowledge of the size and shape of the radial head is necessary for the creation of a radial head prosthesis that is anatomically and biomechanically correct. Twenty-seven measurements, focused on the proximal extremity, were done on 96 radii. The shape of the radial head was determined by the difference between the maximum diameter and the minimum diameter. We considered the shape to be circular when the difference was less than 1 mm, and elliptical when the difference was greater than 1 mm. The shape of the radial head was compared with the neck/diaphysis angle. Fifty-seven percent of radial heads were elliptical and 43% were circular. When the head was elliptical the maximum diameter was 22 mm +/-2.9 and the minimum diameter was 20 mm +/-2.8 ( P<0.001). When the head was circular the maximum diameter was 21.2 mm +/-2.4 and the minimum diameter was 20.4 mm +/-2.4 ( P<0.14). The angle between the neck and the diaphysis varied with regard to the shape of the radial head. It was 166.75 degrees +/-3 for the circular heads and 168.62 degrees +/-3.2 for the elliptical heads ( P<0.01). The biomechanics of the circular shape and the elliptical shape are different, involving an adaptation of the angle between the neck and the radial diaphysis. This difference must be taken in consideration in the design of a radial head prosthesis.

Abstract
The synthesis and characterization of new modified tetrathiafulvalenes (TTF), the S-position isomers of BEDT-TTF and EDT-TTF, are described. The synthetic strategy presented in this work is based on an efficient and unprecedented two-step sequence for the conversion of a vicinal bis(hydroxymethyl) functionality into a disulfide ring. Different routes are discussed in terms of efficiency for the synthesis of the symmetric S-position isomer of BEDT-TTF and that of EDT-TTF. Their electrochemical properties are combined with data obtained from UV/Vis spectroscopy and orbital calculations, and the electronic influence of peripheral sulfur atoms on the neutral and oxidized species is discussed. The introduction of these outer sulfur atoms at the periphery of the TTF core gives rise to specific intermolecular S...S interactions in the corresponding organic materials. Crystallographic studies of radical cation salts synthesized upon electrocrystallization clearly showed that the network obtained is dictated by the outer sulfur atoms, which are responsible for a characteristic and unprecedented "windmill" array.

Abstract
The discovery of later Middle Pleistocene human remains from the Bau de l'Aubesier, France reinforces an evolutionary model of the gradual accumulation of Neandertal-derived facial and dental features during the Middle Pleistocene of the northwestern Old World. The pronounced maxillary incisor beveling of Aubesier 4 helps to extend the antiquity of nondietary use of the anterior dentition. The interproximal "toothpick" groove on the Aubesier 10 molar increases the sample for these lesions. The pathological loss of the mandibular dentition of Aubesier 11 indicates advanced antemortem masticatory impairment, at a level previously undocumented before the Late Pleistocene. These remains support a view of later Middle Pleistocene humans able to support debilitated individuals despite the considerable use of their bodies to accomplish routine activities.

Abstract
Semicarbazide-sensitive amine oxidase (SSAO) is an amine oxidase related to the copper-containing amine oxidase family. The tissular form of SSAO is located at the plasma membrane, and is mainly expressed in vascular smooth muscle cells and adipocytes. Recent studies have suggested that SSAO could activate glucose transport in fat cells. In the present work, we investigated the potential role of a chronic SSAO activation on adipocyte maturation of the 3T3-L1 pre-adipose cell line. Exposure of post-confluent 3T3-L1 pre-adipocytes to methylamine, a physiological substrate of SSAO, promoted adipocyte differentiation in a time- and dose-dependent manner. This effect could be related to SSAO activation, since it was antagonized in the presence of the SSAO inhibitor semicarbazide, but not in the presence of the monoamine oxidase inhibitor pargyline. In addition, methylamine-induced adipocyte maturation was mimicked by 3T3-L1 cell treatment with other SSAO substrates. Finally, the large reversion of methylamine action by catalase indicated that hydrogen peroxide generated by SSAO was involved, at least in part, in the modulation of adipocyte maturation. Taken together, our results suggest that SSAO may contribute to the control of adipose tissue development.

Abstract
A series of redox-responsive ligands that associate the electroactive tetrathiafulvalene core with polyether subunits of various lengths has been synthesized. X-ray structures are provided for each of the free ligands. The requisite structural criteria for reaching switchable ligands are satisfied for the largest macrocycles, that is, planarity of the 1,1',3,3'-tetrathiafulvalene (TTF) pi system and correctly oriented coordinating atoms. The ability of these ligands to recognize various metal cations as a function of the cavity size has been investigated by various techniques (LSIMS, 1H NMR, and UV/Vis spectroscopy, cyclic voltammetry). These systems exhibit an unprecedented high coordination ability among TTF crown ethers. Their switchable ligating properties have been confirmed by cyclic voltammetry, and metal-cation complexation has been illustrated by X-ray structures of three of the corresponding metal complexes (Pb2+, Sr2+, and Ba2+). Solid-state structures of these complexes display original packing modes with channel-like arrangements.
