Abstract
CO2 reacts with simple amines in the presence of water to generate dynamic combinatorial libraries of majority (i.e., ammonium carbamates) and minority (i.e., ammonium carbonates) nonisoenergetic covalent adducts. Over the past two decades, our laboratory has reported on a new class of cavitands, namely, dyn[n]arenes, from which a polyanionic macrocycle is a highly efficient receptor for linear polyammoniums that forms [2]pseudorotaxanes in water at neutral pH. Herein, we demonstrate that the formation of [2]pseudorotaxanes shifts the equilibrium of CO2 capture by polyamines in water toward the quasi-exclusive formation of carbonate adducts, providing the first example of a switch between two competitive and reversible covalent processes triggered by host-guest interactions. In addition, this supramolecular approach to CO2 capture exhibits enhanced capture efficiency by increasing the state of protonation of complexed vs uncomplexed polyamines. Altogether, we report here that a templating approach can divert the outcome of two reversible covalent chemistries involving nucleophilic additions and acid-base reactions, challenging therefore the common knowledge that noncovalent and covalent bonds operate in separate energy frames.

Abstract
Because they hold together molecules by means of non-covalent interactions - relatively weak and thus, potentially reversible - the anionic calixarenes have become an interesting tool for efficiently binding a large range of ligands - from gases to large organic molecules. Being highly water soluble and conveniently biocompatible, they showed growing interest for many interdisciplinary fields, particularly in biology and medicine. Thanks to their intrinsic conical shape, they provide suitable platforms, from vesicles to bilayers. This is a valuable characteristic, as so they mimic the biologically functional architectures. The anionic calixarenes propose efficient alternatives for overcoming the limitations linked to drug delivery and bioavailability, as well as drug resistance along with limiting the undesirable side effects. Moreover, the dynamic non-covalent binding with the drugs enables predictable and on demand drug release, controlled by the stimuli present in the targeted environment. This particular feature instigated the use of these versatile, stimuli-responsive compounds for sensing biomarkers of diverse pathologies. The present review describes the recent achievements of the anionic calixarenes in the field of life science, from drug carriers to biomedical engineering, with a particular outlook on their applications for the diagnosis and treatment of different pathologies.

Abstract
The aim of this study was to formulate and characterize CK2 inhibitor-loaded alginate microbeads via the polymerization method. Different excipients were used in the formulation to improve the penetration of an active agent and to stabilize our preparations. Transcutol® HP was added to the drug-sodium alginate mixture and polyvinylpyrrolidone (PVP) was added to the hardening solution, alone and in combination. To characterize the formulations, mean particle size, scanning electron microscopy analysis, encapsulation efficiency, swelling behavior, an enzymatic stability test and an in vitro dissolution study were performed. The cell viability assay and permeability test were also carried out on the Caco-2 cell line. The anti-oxidant and anti-inflammatory effects of the formulations were finally evaluated. The combination of Transcutol® HP and PVP in the formulation of sodium alginate microbeads could improve the stability, in vitro permeability, anti-oxidant and anti-inflammatory effects of the CK2 inhibitor.

Abstract
The diastereoselective assembly of achiral constituents through a single spontaneous process into complex covalent architectures bearing multiple stereogenic elements still remains a challenge for synthetic chemists. Here, we show that such an extreme level of control can be achieved by implementing stereo-electronic information on synthetic organic building blocks and templates and that non-directional interactions (i.e., electrostatic and steric interactions) can transfer this information to deliver, after self-assembly, high-molecular weight macrocyclic species carrying up to 16 stereogenic elements. Beyond the field of supramolecular chemistry, this proof of concept should stimulate the on-demand production of highly structured polyfunctional architectures.

Abstract
Phospholipase D (PLD) is a ubiquitous enzyme that cleaves the distal phosphoester bond of phospholipids generating phosphatidic acid (PA). In plants, PA is involved in numerous cell responses triggered by stress. Similarly, in mammals, PA is also a second messenger involved in tumorigenesis. PLD is nowadays considered as a therapeutic target and blocking its activity with specific inhibitors constitutes a promising strategy to treat cancers. Starting from already described PLD inhibitors, this study aims to investigate the effect of their structural modifications on the enzyme's activity, as well as identifying new potent inhibitors of eukaryotic PLDs. Being able to purify the plant PLD from Vigna unguiculata (VuPLD), we obtained a SAXS model of its structure. We then used a fluorescence-based test suitable for high-throughput screening to review the effect of eukaryotic PLD inhibitors described in the literature. In this regard, we found that only few molecules were in fact able to inhibit VuPLD and we confirmed that vanadate is the most potent of all with an IC50 around 58 μM. Moreover, the small-scale screening of a chemical library of 3120 compounds allowed us to optimize the different screening's steps and paved the way towards the discovery of new potent inhibitors.

Abstract
During the last two decades, disulfide-based dynamic combinatorial chemistry has been extensively used in the field of molecular recognition to deliver artificial receptors for molecules of biological interest. Commonly, the nature of library members and their relative amounts are provided from HPLC-MS analysis of the libraries, allowing the identification of potential binders for a target (bio)molecule. By re-investigating dynamic combinatorial libraries generated from a simple 2,5-dicarboxy-1,4-dithiophenol building block in water, we herein demonstrated that multiple analytical tools were actually necessary in order to comprehensively describe the libraries in terms of size, stereochemistry, affinity, selectivity, and finally to get a true grasp on the different phenomena at work within dynamic combinatorial systems. We show that multiple analytical tools are necessary in order to describe the different phenomena within disulfide-based dynamic combinatorial libraries in terms of size, stereochemistry, affinity and selectivity.![]()

Abstract
The Eubacterium saburreum serine protease inhibitor from the human gut microbiota inhibits the eukaryotic pancreatic elastase associated with acute pancreatitis. Interestingly, the inhibition efficiency and stability are markedly increased by the para-sulphonato-calix[8]arene capped silver nanoparticles. Moreover, this enzyme is distinguishable by its high inhibitory effect at broad pH range between 2-10 and temperatures from 10 to 40 °C, in the presence of para-sulphonato-calix[8]arene capped silver nanoparticles the enzyme remains active even at 70 °C.

Abstract
3D printing is attracting considerable interest for its capacity to produce prototypes and small production runs rapidly. Fused deposit modeling (FDM) was used to produce polyvalent test plates for investigation of the physical, chemical, and in-vitro biological properties of printed materials. The polyvalent test plates (PVTPs) are poly-lactic acid cylinders, 14 mm in diameter and 3 mm in height. The polymer ester backbone was surface modified by a series of ramified and linear oligoamines to increase its hydrophilicity and introduce a positive charge. The chemical modification was verified by FT-IR spectroscopy, showing the introduction of amide and amine functions, and contact angle measurements confirmed increased hydrophilicity. Morphology studies (SEM, optical microscopy) indicated that the modification of PVTP possessed a planar morphology with small pits. Positron annihilation lifetime spectroscopy demonstrated that the polymeric free volume decreased on modification. An MTT-based prolonged cytotoxicity test using Caco-2 cells showed that the PVTPs are non-toxic at the cellular level. The presence of surface oligoamines on the PVTPs reduced biofilm formation by Candida albicans SC5314 significantly. The results demonstrate that 3D printed objects may be modified at their surface by a simple amidation reaction, resulting in a reduced propensity for biofilm colonization and cellular toxicity.

Abstract
By means of Silicon Nano Tweezers (SNTs) the effects on the mechanical properties of λ-phage DNA during interaction with calf thymus nucleosome to form an artificial chromatin analog were measured. At a concentration of 100 nM, a nucleosome solution induced a strong stiffening effect on DNA (1.1 N m-1). This can be compared to the effects of the histone proteins, H1, H2A, H3 where no changes in the mechanical properties of DNA were observed and the complex of the H3/H4 proteins where a smaller increase in the stiffness is observed (0.2 N m-1). Para-sulphonato-calix[4]arene, SC4, known for epigenetic activity by interacting specifically with the lysine groups of histone proteins, was studied for its effect on an artificial chromatin. Using a microfluidic SNT device, SC4 was titrated against the artificial chromatin, at a concentration of 1 mM in SC4 a considerable increase in stiffness, 15 N m-1, was observed. Simultaneously optical microscopy showed a physical change in the DNA structure between the tips of the SNT device. Electronic and Atomic Force microscopy confirmed this structural re-arrangement. Negative control experiments confirmed that these mechanical and physical effects were induced neither by the acidity of SC4 nor through nonspecific interactions of SC4 on DNA.

Abstract
By using a combination of readily accessible experimental and computational experiments in water, we explored the factors governing the association between polyanionic dyn[4]arene and a series of α,ω-alkyldiammonium ions of increasing chain length. We found that the lock-and-key concept based on the best match between the apolar and polar regions of the molecular partners failed to explain the observed selectivities. Instead, the dissection of the energetic and structural contributions demonstrated that the binding events were actually guided by two crucial solvent-related phenomena as the chain length of the guest increases: the expected decrease of the enthalpic cost of guest desolvation and the unexpected increase of the favourable enthalpy of complex solvation. By bringing to light the decisive enthalpic impact of complex solvation during the binding of polyelectrolytes by inclusion, this study may provide a missing piece to a puzzle that one day could display the global picture of molecular recognition in water.

Abstract
The extension of the family of dyn[ n]arenes toward a three-membered macrocycle is reported. Through a templated approach, a single diastereoisomer of a dyn[3]arene that bears six carboxyl groups could be isolated by precipitation in 59-63% yield and excellent purity (≥95%). A combination of experimental and computational experiments in water at physiological pH revealed that the macrocycle could bind parent biogenic polyamines with a unique diversity of surface-binding modes. Whereas no binding event could be accurately measured with 1,3-diaminopropane, spermidine formed a classical stoichiometric complex with the dyn[3]arene in the millimolar concentration range. On the other hand, the data obtained for spermine could only be attributed to a more complex binding event with the formation of a 2:1 complex at high [host]/[guest] ratios and redistribution toward a 1:1 complex upon further addition of guest.

Abstract
The asymmetric deformation of a dyn[4]arene upon the binding of various lysine derivatives leads to distinct induced circular dichroism outputs in buffered water, which can be exploited not only for the determination of their enantiomeric excesses, but also for their classification by linear discriminant analysis.

Abstract
Phenazine is known to regroup planar nitrogen-containing heterocyclic compounds. It was used here to enhance the bioavailability of the biologically important compound iodinin, which is near insoluble in aqueous solutions. Its water solubility has led to the development of new formulations using diverse amphiphilic α-cyclodextrins (CDs). With the per-[6-desoxy-6-(3-perfluorohexylpropanethio)-2,3-di-O-methyl]-α-CD, we succeeded to get iodinin-loaded nanoformulations with good parameters such as a size of 97.9 nm, 62% encapsulation efficiency and efficient control release. The study presents an interesting alternative to optimizing the water solubility of iodinin by chemical modifications of iodinin.

Abstract
The opportunistic Gram-negative bacterium Burkholderia cenocepacia causes lethal infections in cystic fibrosis patients. Multivalent mannoside derivatives were prepared as potential inhibitors of lectin BC2L-A, one of the virulence factors deployed by B. cenocepacia in the infection process. An (α1→2)-thio-linked mannobioside mimic bearing an azide functionalized aglycon was conjugated to different multivalent scaffolds such as propargylated calix[4]arenes, methyl gallate and pentaerythritol by azide-alkyne 1,3-dipolar cycloaddition. The interaction between the glycoclusters and the mannose binding BC2L-A lectin from B. cenocepacia was examined by isothermal microcalorimetry, surface plasmon resonance, inhibition of yeast agglutination and analytical ultracentrifugation.

Abstract
A family of p-cyclophanes based on bis- or tetrafunctionalized 1,4-bisthiophenol units linked by disulfide bridges was obtained by self-assembly on a gram scale and without any chromatographic purification. The nature of the functionalities borne by these so-called dyn[4]arenes plays a crucial role on their structural features as well as their molecular recognition abilities. Tuning these functions on demand yields tailored receptors for cations, anions, or zwitterions in organic or aqueous media.

Abstract
Silver nanoparticles capped with nine different sulphonated calix[n]arenes were tested for their anti-bacterial effects against B. subtilis and E. coli at an apparent concentration of 100 nM in calix[n]arene. The results show the para-sulphonato-calix[n]arenes are active against Gram positive bacteria and the derivatives having sulphonate groups at both para and alkyl terminal positions are active against Gram negative bacteria. The calix[6]arene derivative with only O-alkyl sulphonate groups shows bactericidal activity.

Abstract
PURPOSE OF INVESTIGATION To describe the French practices regarding contraception after breast cancer in the 2000's. MATERIALS AND METHODS A total of 2,500 forms were sent to gynecologists practicing in France. Inclusion criteria were premenopausal patients who had a history of breast cancer and who had been prescribed contraception after diagnosis. Between June 1, 2002 and January 1, 2003, 197 evaluable responses were retrieved. RESULTS The median age of the sample was 38.5 years. The most commonly used form of contraception was an intrauterine device (n = 144, 73.1%). Hormonal contraception was prescribed for 42 patients (21.3%), and other methods were used in 29 patients (14.7%) (Condoms n = 14, tubal sterilization n = 7, and others n = 8). Recurrence occurred in 27 patients (13%); 2.9% in the progestin group, 16.3% in the IUD group, and 14.8% with the other methods). CONCLUSIONS It is necessary to evaluate current contraception practices after breast cancer to evaluate the efficacy and safety of contraception in these patients.

Abstract
The interactions of silver nanoparticles capped by various calix[n]arenes bearing sulphonate groups at the para and/or phenolic faces with cationic, neutral and anionic surfactants have been studied. Changes in the plasmonic absorption show that only the calix[4]arene derivatives sulphonated at the para-position interact and then only with cationic surfactants. The interactions follow the CMC values of the surfactants either as simple molecules or mixed micelles.

Abstract
This review treats the biological properties of the various anionic calix[n]arenes, both as soluble forms and in the colloidal state. The complexation of these molecules with amino-acids, peptides and proteins is discussed, as is their interaction with model membranes. The complexations with various Active Pharmaceutical Ingredients as complexes, for tamoxifen as solid state and colloidal structures, are treated in depth. Two sections deal with the direct biological action of the calix[n]arenes and their use as biosensors. A final section deals with the toxicity, in reality the lack of toxicity of the calix[n]arenes.

Abstract
Abstract
Background: Breast cancer screening increases the detection of nonpalpable breast lesions, These lesions raise specific concerns, involving radiological imaging, biopsy techniques, and pathological analysis. The objective of the study is to evaluate the management of nonpalpable breast lesions in a breast disease unit.Material and Methods: From 2001 to 2007, 2708 nonpalpable breast lesions were prospectively evaluated by a multidisciplinary team. Radiologic lesions were detected by mammography alone (71,5%), ultrasonography (27,90%), MRI (0,20%). All lesions were classified according to the BI RADS classification. Three hundred and nine (309) core needle biopsies were performed, 807 vacuum assisted biopsies, and 521 open breast biopsies. The pathologic results were correlated with surgery, rebiopsy or long-term imaging follow up.Results: The pathologic results showed 33 % of malignant lesions (DCIS, invasive carcinoma), 9 % of high risk lesions (atypical ductal or lobular hyperplasia, lobular carcinoma in situ) and 58 % of benign lesions. The prevalence of cancer as a function of BI-RADS was: BI-RADS 0 : 2,6% (4/152), BI-RADS 2: 0% (0/55), BI-RADS 3: 2,3% (17/740), BI-RADS 4: 23,4% (352/1502) et BI-RADS 5 : 78,7% (185/235). Twelve of 152 (7,9 %) high risk lesions were upgraded to malignant lesions and 34/211 DCIS (16,1%) were upgraded to invasive carcinoma after surgery. Diagnostic performance rates exhibited the following results: agreement rate=96,6%, sensibility=96,2%, overall underestimation rate=12,6%, and false-negative rate=1,6%.Table 1: Diagnostic performance of core needle biopsy, vacuum assisted biopsy, open breast biopsy core needle biopsy%vacuum assisted biopsy%open breast biopsy%Totaln=309 807 521 1637Pathologic results benign21970,9%48960,6%23444,9%942 (57,5%)High risk82,6%728,9%6813,1%148 (9,0%)malignant8226,5%24630,5%21942,0%547 (33,4%)Diagnostic performance sensibility80/8297,6%228/24593,1%217/21999,1%525/546 (96,2%)agreement304/30998,4%762/80794,4%515/52198,8%1581/1637 (96,6%)high risk underestimate1/616,7%10/7713,0%1/691,4%12/152 (7,9%)DCIS underestimate3/650,0%27/12421,8%4/814,9%34/211 (16,1%)overall underestimate rate4/1330,8%37/20118,4%5/1503,3%46/364 (12,6%)false negative rate1/821,2%7/2462,8%1/2190,5%9/547 (1,6%) After vacuum assisted biopsy, one-step surgery was performed in 82,9% and after core needle biopsy in 68,4%.Conclusion: This kind of quality evaluation in community practice should be encouraged. Management of those lesions continuously evolves with the widespread of RMI and new biopsy techniques. Efforts should be made in exploring imaging-pathologic discrepancies, and in identifying predictive factors of invasion on biopsies. We currently perform a focused analysis on lesions that required two surgical steps despite a prior biopsy, in order to point out new ways to improve our practices.

Abstract
Diamino-bicycloundecane mono-deprotonates H-calix[4]arene and the solid-structure of the resulting salt has been determined by X-ray crystallography. Two different complexes are present in the structure with the Diamino-bicycloundecane cation held in the calix[4]arene cavity by CH-p interactions. In the packing there is a hydrogen-bonded polymeric chain. Both the complexes formed layered structures with differing inter-layer distances.

Abstract
On 24-25 October 2005 a cluster of five haemolytic uraemic syndrome (HUS) cases was reported in southwest France. An investigation was undertaken to identify the outbreak source and implement control measures. Cases were defined as individuals with HUS or diarrhoea with isolation of Escherichia coli O157:H7 in stools or a positive antibody response to E. coli O157 lipopolysaccharide, resident in southwest France with symptom onset after 19 September 2005. Sixty-nine identified patients had symptom onset between 5 October and 3 November 2005, including 17 cases of HUS. One brand of frozen beef burgers produced on 22 August 2005 was consumed by all patients in the week before symptom onset. E. coli O157:H7 strains from patients, patients' burgers and the manufacturing plant were genetically related. This is the largest community-wide outbreak of E. coli O157:H7 in France to date and the first associated with consumption of contaminated frozen beef burgers.

Abstract
The preparation of aqueous suspensions of nanoparticles of the fluorinated amphiphilic alpha-cyclodextrins hexakis[6-deoxy-6-(3-perfluoroalkylpropanethio)-2,3-di-O-methyl]-alpha-cyclodextrin and their hydrocarbon analogues was studied. The complexation of acyclovir by modified alpha-cyclodextrin, the encapsulation efficiency and release profile were measured as an assessment of the properties of such nanoparticles regarding drug delivery applications. Stable aqueous suspensions of nanoparticles were prepared using nanoprecipitation method without using surface-active agent. The organic solvent (ethanol) and cyclodextrin concentration (0.4 mM) were carefully selected. The nanoparticles prepared from these new amphiphilic alpha-cyclodextrin derivatives according to optimized conditions have an average diameter of 100 nm for fluorinated derivatives and 150 nm for hydrocarbon analogues. Suspensions were stable over at least 9 months. Acyclovir forms inclusion complexes of 1:1 stoichiometry and high stability constants (from 700 mol L(-1) to 4000 mol L(-1) in ethanol) as assessed from UV/vis spectroscopy and Electrospray Ionization Mass Spectroscopy. Satisfactory loading of acyclovir inside the nanoparticles was achieved according to the "highly loaded" preparation method (encapsulation efficiency approximately 40%). Nanoparticles based on the fluorinated compounds delayed the drug release up to 3 h with little initial burst release. Fluorinated amphiphilic alpha-cyclodextrins self-assemble in the form of nanospheres that encapsulate acyclovir and allow sustained release, showing their potential for applications to drug delivery.
