Several plants use secondary metabolites against insects and pathogens attack. Among such metabolites known glycoalkaloids are the most studied. Plants from Solanaceae Family are the most abundant on those alkaloids. Despite alfa-tomatine is a known glycoalkaloid, its specific action against Moniliophthora perniciosa, fungi responsible for witches broom disease in cocoa plantations was obtained in this work. Alfa-tomatine was infusion-extracted from Solanum lycopersicum leaves, and its action against the fungi growth was shown on the bioassays. In these tests, M. perniciosa growth was totally inhibited but other fungus tested, the inhibition was not totally, or did not present effect on growth, showing in this way, the specificity of alfa-tomatine to M. perniciosa. The advantages of work with a natural molecule for the fungi control is the stability of the molecule, its resistance to high temperature and pressure and for its use, the simple method of extraction used. The confirmation of the alfa-tomatine molecule was done by High Performance Liquid Chromatography and Mass Spectrometry in comparison to the Sigma standard.

Depression in Climacteric Women:Most Meaningful Symptoms

Background: With population aging occurring worldwide, promoting climacteric women’s health has become the object of important studies. Purpose: Observing the prevalence of depression in climacteric women and their self-evaluation of the depression factors is the main goal of this study. Design: This cross-sectional research is enquiry descriptive. Methods: The sample was composed of 48 climacteric women (between 45 and 65 years old) non-selected volunteers, served by the Centers for Psycho and Social Attention (CAPS) of Specialized Mental Medicine, in Sorocaba, via the Beck Depression Inventory (BDI) questionnaire. Results: Checking the mean and frequency distribution, the climacteric women presented a prevalence of 37.5% of moderate depression (BDIindex = 24.39 ± 3.13), and 47.92% of severe depression (BDIindex = 38.13 ± 6.78). Concerning the symptoms, Spearman rank order correlation was found as the highest concerns, hierarchically: indecision (r = 0.72, p Conclusions: The prevalence of depression in these CAPS climacteric women was considered very high (86% ranking from moderate to severe) caused mostly by indecision, anhedonia, guilt, crying and self-esteem, followed by inutility, self-criticism and loss of concentration.

Quasi-freestanding graphene on Ni（110）： A graphene/ metal contact with suppressed interface states

引用

Nano Research 2016年第6期9卷 1795-1800页

作者： antonio Politano Department of Physics University of Calabria via Ponte Bucci 3 I/C 1-87036 Rende (CS) Italy

Graphene/Ni（110） has been studied by time-resolved X-ray photoelectron spectroscopy and near-edge X-ray absorption fine structure. The C ls core level shows a splitting typical of periodically rippled interfaces. The analysis of the C K-edge reveals that the interface states previously observed for graphene/Ni（111） are suppressed in graphene/Ni（110）. This suppression is due to the reduced hybridization of the Dirac-cone electrons in graphene with the d-bands of the （110）-oriented nickel contacts. Our results show that, contrary to commensurate growth of graphene on Ni（111）, epitaxially grown graphene on Ni（110） behaves as a quasi-freestanding sheet, as the lattice mismatch gives rise to a moir6 reconstruction.

Interplay between the glass and the gel transition

引用

Science China(Physics,Mechanics & Astronomy) 2019年第10期62卷 45-50页

作者： Annalisa Fierro antonio de Candia antonio Coniglio CNR-SPIN c/o Complesso di Monte S.AngeloNapoli 80126Italy Dipartimento di Fisica"Pancini" Universita di Napoli"FedericoⅡ"Complesso di Monte S.AngeloNapoli 80126Italy

By changing the control parameters, many physical systems reach a slow dynamics regime followed by an arrested or a quasiarrested state. Examples, among others, are gels and glasses. In this paper, we discuss some experimental and theoretical results in polymer and colloidal systems, where gel and glass transitions interfere, and use models from Mode Coupling Theory（MCT）to illustrate the rich phenomenology observed. The continuous and the discontinuous transition lines, found in the MCT models,are considered suitable to describe respectively the gel and the glass transitions, so we suggest that the interplay between gel and glass may be interpreted in terms of the F13 MCT model, clarifying also the origin of logarithmic decays often observed in such systems. In particular, the theoretical predictions of the MCT in the F13 model are compared with Molecular Dynamics simulations in model systems for chemical gels and charged colloids.
