Les EROs, à cause du stress oxydant qu’elles génèrent, sont impliquées dans de nombreuses pathologies, notamment l’athérosclérose. Les monoamine oxydases (MAOs) sont deux flavoenzymes responsables de la dégradation des catécholamines et des amines biogènes comme la sérotonine ; elles sont une source importante d’EROs. Il a été montré qu’elles peuvent être impliquées dans la prolifération cellulaire ou l’apoptose du fait du stress oxydant qu’elles génèrent. Ce travail de thèse a montré que la MAO-A, en dégradant son substrat (sérotonine ou tyramine), active une voie de signalisation mitogène particulière : la voie métalloprotéase- 2/sphingolipides (MMP2/sphingolipides), et contribue à la prolifération de cellules musculaire lisses vasculaires induite par ces monoamines. De plus, une étude complémentaire a confirmé l’importance des EROs comme stimulus mitogène (utilisation de peroxyde d’hydrogène exogène), et a décrit plus spécifiquement les étapes en amont de l’activation de MMP2, ainsi que l’activation par la MMP2 de la sphingomyélinase neutre (première enzyme de la cascade des sphingolipides).

Abstract: In the present work, an Ir/CeO2 catalyst was prepared by the deposition–precipitation method and tested in the decomposition of hydrazine hydrate to hydrogen, which is very important in the development of hydrogen storage materials for fuel cells. The catalyst was characterised using different techniques, i.e., X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), scanning electron microscopy (SEM) equipped with X-ray detector (EDX) and inductively coupled plasma—mass spectroscopy (ICP-MS). The effect of reaction conditions on the activity and selectivity of the material was evaluated in this study, modifying parameters such as temperature, the mass of the catalyst, stirring speed and concentration of base in order to find the optimal conditions of reaction, which allow performing the test in a kinetically limited regime.

  • Periodic Trends in the Main Group Elements
    Chemistry of The Main Group Elements 1. Hydrogen Hydrogen is the most abundant element in the universe, but it accounts for less than 1% (by mass) in the Earth’s crust. It is the third most abundant element in the living system. There are three naturally occurring isotopes of hydrogen: hydrogen (1H) - the most abundant isotope, deuterium (2H), and tritium 3 ( H) which is radioactive. Most of hydrogen occurs as H2O, hydrocarbon, and biological compounds. Hydrogen is a colorless gas with m.p. = -259oC (14 K) and b.p. = -253oC (20 K). Hydrogen is placed in Group 1A (1), together with alkali metals, because of its single electron in the valence shell and its common oxidation state of +1. However, it is physically and chemically different from any of the alkali metals. Hydrogen reacts with reactive metals (such as those of Group 1A and 2A) to for metal hydrides, where hydrogen is the anion with a “-1” charge. Because of this hydrogen may also be placed in Group 7A (17) together with the halogens. Like other nonmetals, hydrogen has a relatively high ionization energy (I.E. = 1311 kJ/mol), and its electronegativity is 2.1 (twice as high as those of alkali metals). Reactions of Hydrogen with Reactive Metals to form Salt like Hydrides Hydrogen reacts with reactive metals to form ionic (salt like) hydrides: 2Li(s) + H2(g) 2LiH(s); Ca(s) + H2(g) CaH2(s); The hydrides are very reactive and act as a strong base. It reacts violently with water to produce hydrogen gas: NaH(s) + H2O(l) NaOH(aq) + H2(g); It is also a strong reducing agent and is used to reduce TiCl4 to titanium metal: TiCl4(l) + 4LiH(s) Ti(s) + 4LiCl(s) + 2H2(g) Reactions of Hydrogen with Nonmetals Hydrogen reacts with nonmetals to form covalent compounds such as HF, HCl, HBr, HI, H2O, H2S, NH3, CH4, and other organic and biological compounds.

Academic Editor: Derek J. McPhee Received: 25 November 2014 / Accepted: 15 February 2015 / Published: 19 February 2015 Abstract: Glycation is an ageing reaction of naturally occurring sugars with dermal proteins, with clinical signs appearing in vivo around age 30, and increasing steadily/regularly with age. The suppleness of the dermis is affected by the formation of bridges between proteins and sugars (Maillard’s reaction). The accumulation of advanced glycation end products (AGEs) in skin plays a very important role in skin ageing. Therefore, natural compounds or extracts that possess antiglycation activities may have great anti-ageing potential. In the present study, Silybum marianum flower extract (SMFE) was demonstrated to possess antiglycation activity. We found that SMFE inhibits glycation reaction between BSA and glucose. In addition, antiglycation activity of SMFE was confirmed in a human skin explants model.

  • Dihydrazides - the Versatile Curing Agent for Solid Dispersion Systems
    Dihydrazides - The Versatile Curing Agent for Solid Dispersion Systems Abe Goldstein A&C Catalysts, Inc Abstract This paper will introduce dihydrazides, a relatively obscure class of curing agents useful in virtually all thermoset resin systems. First described in 1958, by Wear, et al.(1) dihydrazides are useful curing agents for epoxy resins, chain extenders for polyurethanes, and excellent crosslinking agents for acrylics. In one-part epoxy systems, depending on the backbone chain of the chosen dihydrazide, Tg's over 150°C and pot life over 6 months as cure time of less than a minute can be seen. In acrylic emulsions, dihydrazides can be dissolved into the water phase and serve as an additional crosslinker, as the emulsion coalesces and cures. As a chain extender for poylurethanes, dihydrazides can be used to increase toughness and reduce yellowing. Introduction O O | | | | Dihydrazides are represented by the active group: H2NHNC(R) CNHNH2, where R is can be any polyvalent organic radical preferably derived from a carboxylic acid. Carboxylic acid esters are reacted with hydrazine hydrate in an alcohol solution using a catalyst and a water extraction step. The most common dihydrazides include adipic acid dihydrazide (ADH), derived from adipic acid, sebacic acid dihydrazide (SDH), valine dihydrazide (VDH), derived from the amino acid valine, and isophthalic dihydrazide (IDH). The aliphatic R group can be of any length. For example, when R group is just carbon, the resulting compound is carbodihydrazide (CDH), the fastest dihydrazide. Or R as long as C-18 has been reported as in icosanedioic acid dihydrazide (LDH). Some of the more common dihydrazides are represented in Figure 1.

A parameterization of the classical molecular interaction models is carried out by using quan- tum chemical calculations and subsequent fitting to experimental vapor pressure and saturated liquid density data. To validate the molecular models, vapor-liquid equilibria for the pure hydrazines and binary hydrazine mixtures with Water and Ammonia are calculated and compared with the available experimen- tal data. In addition, the Henry’s law constant for the physical solubility of Argon, Nitrogen and Carbon Monoxide in liquid Hydrazine, Monomethylhydrazine and Dimethylhydrazine is computed. In general, the simulation results are in very good agreement with the experimental data. ∗ corresponding author, tel.: +49-5251/60-2421, fax: +49-5251/60-3522, email: [email protected] 1 1 Introduction On October 24, 1960, the greatest disaster in the history of rocketry, now also known as Nedelin disaster, occurred [1–3].

Where the work of other authors is referred to, this is clearly indicated. ABSTRACT OF THESIS Some historical aspects of the oxidation reactions of 1,1-disub- stituted hydrazines are reviewed. In particular, the evidence for the proposed intermediacy of diazenes in these reactions is outlined and the nature of the oxidation products is considered in the broader context of diazene-generating reactions. The synthesis of l-alkyl-l-phenylhydrazines has been examined and several preparative procedures are discussed. The alkylation of the sodium salt of phenyihydrazine with the appropriate alkyl halides was found to be the most successful method; the hydrazines prepared in this way all had substituents of the allylic type. Purification (to remove residual phenyihydrazine) can be achieved by selective recrystallisation of the hydrochloride derivative from benzene. Some limitations of this general method are described. The oxidation studies were carried out using lead tetra-acetate and mercuric oxide.
