Published: October 2017

Imidacloprid is active compounds in Confidor 200 SL with have toxical character. Degradation of Imidacloprid in Advanced Oxidation Processes (AOPs) method by using TiO2 catalyst can reduce toxic level. Advanced Oxidation Processes (AOPs) method which is used is Sonolysis, Photolysis, and Ozonolisis. The result of sonolysis, Photolysis, and Ozonolysis measured by spectrophotometer UV-Vis with λ 400-600 nm, and than optimum degradation waste after addition of catalys measured by HPLC. The result of degradation of Imidacloprid 6 mg/L using sonolysis without addition catalys is more smallest from addition catalys which degradated in 60 minute, temperature 25±1 °C. At the same time with Photolysis methode for addition catalys we get the degradation is more biggest from addition catalys. Degradation percentage of imidacloprid without addition of TiO2-anatase reach is small from with addition of TiO2. Measure using HPLC for each methode we get more than one peak in chromatogram. It means there are other coumpounds in imidacloprid solution.

Associations Among Quadriceps Strength and Rate of Torque Development 6 Weeks Post Anterior Cruciate Ligament Reconstruction and Future Hop and Vertical Jump Performance: A Prospective Cohort Study
Authors: Pua Yong-Hao , Mentiplay Benjamin F. , Clark Ross A. , Ho Jia-Ying 
Published: October 2017

Study Design Prospective cohort. Background Quadriceps strength is associated with hop distance and jump height in persons who have undergone anterior cruciate ligament (ACL) reconstruction. However, it is unknown whether the ability to rapidly generate quadriceps torque in the early phase of recovery is associated with future hopping and jumping performance in this population. Objective To evaluate the prospective associations among quadriceps strength and rate of torque development (RTD) and single-leg hop for distance, vertical jump height, vertical ground reaction force (vGRF), and vertical force loading rate during a landing task in persons who have undergone ACL reconstruction. Methods Seventy patients with unilateral ACL reconstruction participated. At 6 weeks post ACL reconstruction, isometric quadriceps strength and RTD were measured using a dynamometer. At 6 months following ACL reconstruction, patients performed the single-leg hop for distance test. Patients also performed the single-leg vertical jump test on a force plate that measured maximum jump height, vGRF, and average loading rate during landing. Results Both quadriceps strength and RTD at 6 weeks post ACL reconstruction were associated with all hopping and jumping measures at 6 months post ACL reconstruction (P≤.04). Single-leg hop distance was associated more closely with quadriceps strength than with quadriceps RTD (P = .05), and vertical jump height and vGRF measures were associated more closely with quadriceps RTD than with quadriceps strength (P = .05 and P<.01, respectively). Both quadriceps measures were associated with loading rate. Conclusion Quadriceps strength and RTD are complementary but distinct predictors of future hopping and jumping performance in persons who have undergone ACL reconstruction. These findings may contribute to improved rehabilitation of patients who are at risk for poor jumping/hopping performance and abnormal knee loading. J Orthop Sports Phys Ther 2017;47(11):845–852.

La conjugalité dans (tous) ses états ! Usages des tic , couple conjugal, couple parental
Authors: Le Douarin Laurence 
Published: October 2017

Dans quelle mesure les outils numériques dans les familles révèlent-ils, transforment-ils ou déplacent-ils les relations conjugales ? En prenant appui sur deux terrains explorés par des méthodes qualitatives, l’article explore deux angles d’analyse de la conjugalité à l’ère numérique : d’abord, les déplacements opérés dans la division du travail domestique et éducatif entre conjoints par le recours aux outils de communication. Les courriels et les sms contribuent-ils à dévoiler le « travail invisible » et à redistribuer la charge mentale entre conjoints ? Ensuite, l’auteur aborde le rôle des outils numériques dans un contexte où la gestion des séparations et des divorces vise le maintien de la coparentalité : comment les technologies de communication permettent-elles ou non d’asseoir le couple parental à défaut du couple conjugal ?
Parents et addiction aux jeux vidéo… de leur enfant : un symptôme écran de la dépression à l’adolescence ?
Authors: Bellevergue Steve 
Published: October 2017

Premier loisir audiovisuel français, le jeu vidéo fascine, inquiète et perturbe les repères éducatifs des familles. Motif de consultation fréquent dans la clinique contemporaine des professionnels, l’addiction au jeu vidéo interroge tout autant sur sa pertinence terminologique que sur les formes qu’elle revêt à l’adolescence. L’article propose d’exposer quelques repères de la littérature scientifique existante sur l’addiction au jeu vidéo et de la mettre en perspective avec les troubles concomitants comme la phobie scolaire et la dépression. La réflexion clinico-théorique s’appuie sur le cas d’un adolescent reçu au sein d’une mda (maison de l’adolescent). Cette étude de cas repose sur l’articulation entre éléments d’entretiens et analyse de l’évaluation psychologique d’un jeune homme de 16 ans. Ceci permettra de discuter l’hypothèse selon laquelle l’espace du jeu vidéo représente un expédient narcissique élaboratif et soutient un aménagement défensif spécifique face à la dépression, en résonance à la désidéalisation parentale.
La grossesse adolescente, au carrefour de virtualités plurielles
Authors: Missonnier Sylvain , Vlachopoulou Xanthie 
Published: October 2017

La clinique du virtuel constitue un champ, d’apparence nouveau, où l’humain est pensé dans le lien inextricable qu’il entretient avec les outils technologiques qu’il côtoie dans son quotidien, ces réalités virtuelles qui rencontrent sa réalité psychique. À la croisée des processus de parentalité périnatale et d’adolescence, l’espace conceptuel du virtuel offre un cadre théorique et clinique heuristique. Les jalons d’une « relation d’objet virtuelle » y sont posés dans cette rencontre entre la virtualité processuelle du devenir adulte et du devenir parent, enrichie par la rencontre avec le virtuel technoscientifique. La grossesse adolescente est une violente collusion du virtuel adolescent et générationnel. Le récit d’une intervention psychothérapique à la maternité dans ce contexte donne l’occasion d’étudier le dynamisme en plein et en creux d’une relation d’objet virtuelle singulière.
Naissance et résistance d’une revue : Présence africaine
Authors: Allouache Ferroudja 
Published: October 2017

Présence africaine est née dans le contexte colonial d’après guerre, période peu propice aux initiatives des élites en situation de domination : répression dans les colonies, censure, manque de moyens financiers, concurrence d’autres revues. Figure de rassembleur, stratège, Alioune Diop est cependant parvenu à se frayer une place dans le milieu littéraire colonial et postcolonial : sa revue, dédiée au monde noir, a su résister à l’idéologie de son temps, imposer une existence dans la durée, comme en témoignent les archives (lettres, brouillons).
Louis XVI, Vergennes and the American Independence
Authors: Hardman John 
Published: October 2017

This paper concentrates mainly on why France entered the American War. Louis XVI later claimed that his ministers took advantage of his youth to involve him in a war which led to the French Revolution. In fact from his accession aged nineteen, Louis, the precocious pupil of the great diplomatist Abbé Jean-Ignace de La Ville, knew precisely what he was doing. His youth as Dauphin had been dominated by the catastrophic French defeats in the Seven Years’ War. La Ville had published on the American origins of that war. Louis was possessed by a fatal attraction for England and the sea. He had a Catullan love/hate relationship with England – teaching himself the language, mastering the complexities of the political system (better than those of his own), but nevertheless seeking a naval rearmament that had no peaceful rationale. His initial and correct response to the American War was to let England and its colonies slug it out to “leur destruction mutuelle”. We will examine why he changed his mind and Vergennes’s role in this.

Abstract
Intestinal IL-17–producing cells, including Th17, γ/δ T, and innate lymphoid cells, are differentially distributed along the gastrointestinal tract. In this study, we show that the gut IL-17–producing γ/δ T (γ/δ T17) cells develop before birth and persist in the tissue as long-lived cells with minimal turnover. Most colon γ/δ T17 cells express, together with Vγ4 and CCR6, the scavenger receptor 2 and are mainly restricted to innate lymphoid follicles in the colon. Colon γ/δ T cells in mice that lack conventional dendritic cells 2 produced increased amounts of IL-17 with concomitant heightened epithelial antimicrobial response, such as the C-type lectins Reg3γ and Reg3β. In the absence of γ/δ T cells or after IL-17 neutralization, this epithelial response was dramatically reduced, underlining the protective role of this unique subpopulation of innate γ/δ T17 cells in the colonic mucosa.

Published: October 2017

AbstractAs an important characteristic of many creatures, structural colors play a crucial role in the survival of organisms. Inspired by these features, an intelligent structural color material with a heterogeneous striped pattern and stimuli‐responsivity by fast self‐assembly of colloidal nanoparticles in capillaries with a certain diameter range are presented here. The width, spacing, color, and even combination of the structural color stripe patterns can be precisely tailored by adjusting the self‐assembly parameters. Attractively, with the integration of a near‐infrared (NIR) light responsive graphene hydrogel into the structural color stripe pattern, the materials are endowed with light‐controlled reversible bending behavior with self‐reporting color indication. It is demonstrated that the striped structural color materials can be used as NIR‐light‐triggered dynamic barcode labels for the anti‐counterfeiting of different products. These features of the bioinspired structural color stripe pattern materials indicate their potential values for mimicking structural color organisms, which will find important applications in constructing intelligent sensors, anti‐counterfeiting devices, and so on.

AbstractA general protocol for iridium catalyzed direct C−H amidation of cyclic N‐sulfonyl ketimines using sulfonyl, acyl and aryl azides as nitrogen source is reported herein. The reaction takes place at room temperature with acyl and aryl azides, while an elevated temperature needed with sulfonyl azides to furnish aminated sultams in excellent yields with complete chemo and regioselectivity, thus providing a robust and environmentally benign process to the synthesis of aminosultams.magnified image
Directed C–H Alkenylation of Aryl Imines with Alkenyl Phosphates Promoted by a Cobalt–N‐Heterocyclic Carbene Catalyst
Authors: Lee Pin‐Sheng , Xu Wengang , Yoshikai Naohiko 
Published: October 2017

AbstractWe report herein an ortho‐C–H alkenylation reaction of aryl imines with alkenyl phosphates promoted by a cobalt–N‐heterocyclic carbene (NHC) catalytic system. While commercially available bulky NHC ligands exhibited only modest catalytic activity, elaboration of the nitrogen substituents and backbone of the NHC enabled the desired transformation to proceed in high yield at a mild temperature. The new Co–NHC system proved applicable to a variety of aryl imines and alkenyl phosphates to afford ortho‐alkenylated aryl imines, which serve as precursors to benzofulvene derivatives.magnified image

AbstractA key target in molecular electronics has been molecules having switchable electrical properties. Switching between two electrical states has been demonstrated using such stimuli as light, electrochemical voltage, complexation and mechanical modulation. A classic example of the latter is the switching of 4,4′‐bipyridine, leading to conductance modulation of around 1 order of magnitude. Here, we describe the use of side‐group chemistry to control the properties of a single‐molecule electromechanical switch, which can be cycled between two conductance states by repeated compression and elongation. While bulky alkyl substituents inhibit the switching behavior, π‐conjugated side‐groups reinstate it. DFT calculations show that weak interactions between aryl moieties and the metallic electrodes are responsible for the observed phenomenon. This represents a significant expansion of the single‐molecule electronics “tool‐box” for the design of junctions with electromechanical properties.

AbstractWe report the discovery of a new bioorthogonal click‐and‐release reaction involving iminosydnones and strained alkynes. This transformation leads to two products resulting from the ligation and fragmentation of iminosydnones under physiological conditions. Optimized iminosydnones were successfully used to design innovative cleavable linkers for protein modification, thus opening up new areas in the fields of drug release and target‐fishing applications. This click‐and‐release technology offers the possibility of exchanging tags on proteins for functionalized cyclooctynes under mild and bioorthogonal conditions.

Published: October 2017

AbstractAn unstable conjugated homoporphyrin was successfully stabilized by introducing meso‐aryl substitutents. It was evident from the moderate diatropic ring current found by NMR analysis that the newly formed 20π conjugated free base and its protonated form exhibited Möbius aromatic character. Furthermore, complexation as a ligand with an RhI ion afforded a unique binding mode and retained the Möbius aromaticity. Overall, these compounds are the smallest Möbius aromatic molecules, as confirmed by spectral and crystal‐structure analysis and supported by theoretical studies.

Published: October 2017

AbstractModification of nuclear and cytoplasmic proteins by the addition or removal of O‐GlcNAc dynamically impacts multiple biological processes. Here, we present the development of a chemoenzymatic histology method for the detection of O‐GlcNAc in tissue specimens. We applied this method to screen murine organs, uncovering specific O‐GlcNAc distribution patterns in different tissue structures. We then utilized our histology method for O‐GlcNAc detection in human brain specimens from healthy donors and donors with Alzheimer's disease and found higher levels of O‐GlcNAc in specimens from healthy donors. We also performed an analysis using a multiple cancer tissue array, uncovering different O‐GlcNAc levels between healthy and cancerous tissues, as well as different O‐GlcNAc cellular distributions within certain tissue specimens. This chemoenzymatic histology method therefore holds great potential for revealing the biology of O‐GlcNAc in physiopathological processes.
The Complex Solid‐State Landscape of Sodium Diatrizoate Hydrates
Authors: Najib Mohd Nadzri Mohd , Back Kevin , Edkins Katharina 
Published: October 2017

AbstractPharmaceutical sodium salts are prone to incorporate water into their crystal structures. The model compound diatrizoic acid monosodium salt, an X‐ray contrast agent, has been investigated in depth towards its interaction with water in the solid state. Five hydrates with water content ranging from 0.3 to 8 molar equivalents of water show a high degree of interconvertibility, stoichiometric and non‐stoichiometric behaviour, and potential of amorphisation during release of water. A DMSO/water mixed solvate further highlights the high attraction of this salt to incorporate water. All incorporated solvent coordinates to the sodium cation and can further interact and stabilise the respective crystal forms by hydrogen bonding. DTS thus highlights the importance of an in‐depth investigation of sodium salts used pharmaceutically to guarantee dose uniformity and stability of final formulation.
Rhodium‐Induced Reversible C−C Bond Cleavage: Transformations of Rhodium(III) 22‐Alkyl‐m‐benziporphyrins

Published: October 2017

AbstractThe structurally prearranged carbaporphyrins 22‐methyl‐ and 22‐ethyl‐m‐benziporphyrins provide the platform stabilizing aromatic rhodium(III) 22‐(μ‐methylene‐m‐benziporphyrin) and rhodium(III) 22‐(μ‐ethylidene‐m‐benziporphyrin). An intramolecular conversion facilitated by the m‐phenylene reactivity and observed for both aromatic complexes efficiently leads to rhodium(III) 21‐(μ‐methylene)‐21‐carbaporphyrin and rhodium(III) 21‐(μ‐ethylidene)‐21‐carbaporphyrin. The distinctive macrocyclic environment of rhodium(III) 21‐carbaporphyrin created an opportunity to trap unique organometallic transformations of inner core substituents affording the fulvene‐like bond pattern or the rearrangement to 21‐vinyl substituent. The one‐electron reduction of the rhodium(III) carbaporphyrin anion π‐radical with a (dxy)2(dxz)2(dyz)2–(P.−) electronic configuration is demonstrated. The further process of reduction of paramagnetic species triggers the ethyl migration from carbon(22) to rhodium(III), affording the diamagnetic rhodium(III) meta‐benziporphyrin containing the apically coordinated σ‐ethyl ligand providing an example of reversible C(sp2)−C(sp3) bond cleavage.
