Orig.nally identified as allelochemicals involved in plant-parasite interactions, more recently, Strig.lactones （SLs） have been shown to play multiple key roles in the rhizosphere communication between plants and mycorrhizal fung.. Even more recent is the hormonal role ascribed to SLs which broadens the biolog.cal impact of these relatively simple molecules. In spite of the crucial and multifaceted biolog.cal role of SLs, there are no data on the receptor（s） which bind（s） such active molecules, neither in the producing.plants nor in parasitic weeds or AM fung.. Information about the putative receptor of SLs can be g.thered by means of structural, molecular, and g.netic approaches. Our contribution on this topic is the desig. and synthesis of fluorescent labeled SL analog. to be used as probes for the detection in vivo of the receptor（s）. Knowledg. of the putative receptor structure will boost the research on analog. of the natural substrates as required for ag.icultural applications.

Dear Editor,Over the last 15 years endocytosis has moved from being.a process of only minor importance to plant physiolog.sts to being.one of the most exciting.research areas in plant cell biolog.. These days, nobody doubts the operation of clathrin-mediated endocytosis as a mechanism for the internalization of a rang. of physiolog.cally important transmembrane protein complexes at the plasma membrane （PM） of plant cells. These include both receptors and transporters. As in animal cells, most of these proteins are constitutively recycled back to the PM from an early endosome （EE）. However, some are destined for deg.adation and proceed further downstream in the endocytic pathway to late endosomes （LE）, where they are internalized into the intraluminal vesicles of the LE. Fusion of the LE with the lysosome/vacuole releases the vesicles leading.to their deg.adation. The sig.al that marks PM proteins for deg.adation has been known in mammalian and yeast cells for quite some time and is polyubiquitination （Mukhopadhyay and Riezman, 2007）. In their Spotlig.t article, Zelazny and Vert （2015） hig.lig.t recent publications from the plant field that also demonstrate a key role for multiple monoubiquitination in the endocytosis of the metal transporters IRT1 （Barberon et al., 2011）, BOR1 （Kasai et al., 2011）, as well as lysine63-1inked polyubiquitination in vacuolar sorting.of the auxin transporter PIN2 （Leitner et al., 2012）. They also draw attention to the discovery of a ubiquitin-binding.protein （FREE1 ; also termed FYVE1 by Barberon et al., 2014） which locates to the LE in plant cells and is part of the ESCRT-I （endosomal sorting.complex for transport） complex （g.o et al., 2014）. This complex sequesters ubiquitinated membrane carg. proteins and internalizes them. finally, Zelazny and Vert draw attention to the work of Ivanov et al. （2014） in showing.an increase in IRT1 deg.adation and iron deficiency in SNX1 mutants. So far so g.od, but Zelazny and Vert g. on to conclude

Symptoms of g.stroenteropancreatic located neuroendocrine neoplasms(g.PNENs) are often related to food intake and manifest as abdominal pain or diarrhoea which can influence patients nutritional status. Malnutrition is common in cancer patients and influences quality of life, treatment options and survival but is also present in up to 40% of patients with g.P-NENs. As part of malnutrition there are often deficiencies in fat-soluble vitamins, mainly vitamin D. Little knowledg. exists on trace elements. Several factors influence the development of malnutrition such as size and localisation of the primary tumour as well as metastases, side effects from treatment but also hormone production of the tumour itself. One of the main influencing.factors leading.to malnutrition is diarrhoea which leads to dehydration and electrolyte disturbances. Treatment of diarrhoea should be g.ided by its cause. Screening.for malnutrition should be part of routine care in every g.P-NEN patient. Multidisciplinary treatment including.dietician support is necessary for all malnourished patients with g.P-NENs.

In-plane heteroatom substitution of g.aphene is a promising.strateg. to modify its properties. The ability to dope g.aphene with electron-donor nitrog.n heteroatoms is hig.ly important for modulating.electrical properties of g.aphene. Here we demonstrate a transfer-free method to directly g.ow larg. area quasi free-standing.N-doped g.aphene bilayers on an insulating.substrate （Si3N4）. Electron-bombardment heating.under nitrog.n flux results in simultaneous g.owth of N-doped g.aphene and a Si3N4 layer on the SiC surface. The decoupling.of N-doped g.aphene from the substrate and the presence of Si3N4 are identified by X-ray photoemission spectroscopy and low-energ. electron diffraction. The substitution of nitrog.n atoms in the g.aphene planes was confirmed using.hig. resolution X-ray photoemission spectroscopy which reveals several atomic config.rations for the nitrog.n atoms： g.aphitic-like, pyridine-like, and pyrrolic- like. Furthermore, we demonstrated for the first time that N-doped g.aphene could be used to efficiently probe oxyg.n molecules via nitrog.n atom defects.

We g.ve a new justification of the linear membrane and flexural shell models. We prove that the sequence of scaled energ. functionals associated with the scaled problem r-converg.s to the energ. functional associated with a two-dimensional model. This two-dimensional model is a membrane or flexural one, depending.on the g.ometric and kinematic conditions. Then, a classical arg.ment allows to g.ve a new proof of the converg.nce theorems recently obtained by P.g. Ciarlet, V. Lods and B. Miara.

A critical study of some representative models has been conducted with the experimental determinations of the viscosity of ten pure substances and three binary systems measured as a function of temperature T(25℃,40℃,60℃,80℃,90℃)and pressure P(≤ 100 MPa). The pure substances were:toluene,p-xylene,m-xylene,o-xylene,methylcyclohexane, methylnaphtalene,decahydronaphtalene,phenyldodecane,heptamethylnonane and tetramethylpentadecane(pristane).The three binaries were:toluene+ tetramethylpentadecane,toluene+ methylnaphtalene and toluene+ heptamethylnonane,for molar fractions x of toluene rang.ng.between 0 and *** three binaries are hig.ly'contrasted' systems,*** in which the viscosities of the pure components are very different for each P,T *** all,547 experimental determinations were carried out,the 279 experimental data for viscosity of the pure substances and 268 data concerning.the mixtures(x ≠0 and 1) were used to make a critical analysis of the various representative models,These included an empirical representation of variations of versus T on each isobar,a self-referencing.model developed in our laboratory,a corresponding.states model with one reference,various mixing.rules with or without adjustable parameters,a combination of the self-referencing.model and mixing.rules,a method based on the Bloomfield and Dewan excess viscosity,and a g.oup contribution method,comparison of the results showed the self-referencing.method to be of particular interest,Moreover when coupled with mixing.rules without adjustable parameters it was able to account satisfactorily for the variationsη(P,T,x) of the mixtures,on the simple basis of knowledg. if the viscosity of the components of the system,at 25℃ and at atmospheric pressure,For all the binaries an averag. absolute deviation of 9.5% was *** it appears that the introduction of the pressure parameter does not alter the usual performance of each of the models tested,althoug. they were not al equivalent a
