标题:Efficacy Of Photodynamic Therapy Using Tio2 Nanoparticles Doped With Zn And Hypericin In The Treatment Of Cutaneous Leishmaniasis Caused By Leishmania Amazonensis
摘要:Since Leishmania Parasites Exhibit Resistance Outbreaks To Drugs Conventionally Used In Medical Treatments,Research Of New Antileishmanial Compounds Or Alternative Treatment Therapies Are Essential. A Focus Of Interest Has Been The Implementation Of Light-Based Therapies Such As Photodynamic Therapy,Where Inorganic Compounds Such As Titanium Dioxide Have Shown Promising Results As Drug Delivery Carriers. In This Work,Nanoparticles Of Tio2 Doped With Zn (Tio2/zn) Were Synthesized Through Solution Combustion Route And With Hypericin (Hy) In Order To Enhance Its Photodynamic Activity In The Visible Light Region. Scanning (Sem) And Transmission (Tem) Electron Microscopy Analyses Showed Particles Of (Tio2/zn) With Sizes Smaller Than 20 Nm And Formation Of Aggregates Smaller Than 1 Mu M,Whilst Electron Diffraction Spectroscopy (Eds) Analysis Ensured The Presence Of Zn In The System. The Association Of The Tio2/zn With Hy (Tio2/zn-Hy) Was Further Confirmed By Fluorescence Spectrometry. Measurements Of Its Cellular Uptake Showed The Presence Of Smaller Molecules Into Promastigotes After 120 Min Incubation. Tio2/zn-Hy Showed Good Antileishmanial Activity (Ec50 Of 17.5 +/-0.2 Mu G Ml(-1)) And Low Cytotoxicity Against Murine Macrophages (Cc50 35.2 +/-0.3 Mu G Ml(-1)) In The Visible Light (22 Mw Cm(-2) ; 52.8 J Cm(-2)). Moreover,In The In Vivo Analysis,Tio2/zn-Hy Decreased The Parasite Load Of L. Amazonensis-Balb/c Infected Mice By 43%-58% After A Combination Of Blue And Red Light Presenting 22 Mw Cm(-2 )Of Intensity And 52.8 J Cm(-2) Of Fluency Delivered. All Together,These Data Indicate A New Combined System Of Nanoparticles Associated With A Photosensitizer And Pdt As Alternative To Amphotericin B For The Treatment Of Cutaneous Leishmaniasis.

权利人:PAUL JEAN-MICHEL; ARKEMA FRANCE
摘要:The subject of the invention is a method for the synthesis of (meth)acrylic esters by transesterification in the presence of a catalyst corresponding to the formula [(R′O) 3 Ti] x R″ in which R′ is a linear or branched alkyl radical having from 2 to 8 carbon atoms which may contain heteroatoms or R′ is a phenyl radical, R′ is a polyfunctional radical, originating from a polyol R′(OH) x comprising x alcohol functional groups and x is an integer ranging from 2 to 6. The method according to the invention is particularly well suited to the synthesis of dialkylaminoalkyl (meth)acrylates from methyl (meth)acrylate and a dialkylaminoalcohol.

权利人:UNIV LEHIGH
摘要:Provided herein is a hydrothermal process for the rapid synthesis of inorganic nanomaterials (e.g., nanofibers) containing sodium, bismuth, titanium, and oxygen, as well as new compositions made thereby. The process involves heating an aqueous solution or suspension of suitable salts of aforementioned elements at elevated temperature and pressure under constant stirring in a hermetically sealed vessel for a predetermined amount of time (e.g., less than two hours). The powder thus obtained contains nanofibers of rectangular cross-section, with the smallest fibers typically have a cross section of 16 nm×40 nm. Example fibers made by such processes have an aspect ratio exceeding 200.

摘要:The invention relates to a method for obtaining a polylactide polyol by ring-opening polymerization of lactide with lactide and a polyol as direct raw materials. The method includes the following steps: A, lactide purification: a lactide crude product is purified to obtain lactide with a content of more than 99.5% and an optical purity of more than 99%; B, synthesis of polylactide polyol: the purified lactide and the polyol are added into a reaction kettle, then a catalyst is added, in a weight ratio to lactide of 0.5/1000-1/1000, into the reaction kettle for polymerization, and polylactide polyol with a viscosity average molecular weight of 100-5000 is obtained, wherein the catalyst is a composite catalyst of one or more of zinc lactate, zinc oxide, zinc powder, diethyl zinc, tin lactate, tin oxide, tin dioxide, stannous oxide, stannous lactate, stannous octoate, stannous chloride, tin powder, propanoic acid or tetrabutyl titanate. The method of the invention has a simple process and easy operation, is suitable for industrialized production applications, and has no 'three wastes' emissions.

摘要:The present invention discloses a method for synthesis of narrowly dipsersed colloidal PbS nanocrystals that offer size-tunable near-infrared emission. The stability and processibility of these near-infrared emitting quantum dots makes them ideal materials for device applications. The use of cost-effective and non-pyrophoric precursors as well as the success of larger scale reactions means the present invention provides a method for the industrial scale production of PbS nanocrystals.

摘要:The subject of the invention is anatase nanoparticles and ways of the synthesis thereof by a gel- sol method from sodium titanate, which is produced from metatitanic acid in a reaction with NaOH. The molar ratio between NaOH and TiO 2 must be low for a synthesis of sodium titanate, if the goal is to synthetize anatase, i. e. is between 1 :3 to 1 : 1. If the goal is to synthetize rutile, the molar ratio must be higher, at least between 3: 1 to 4: 1. In the gel-sol reaction between sodium titanate and acid very small anatase particles are formed that are of spherical morphology, polycrystalline and present in the acidic suspension. The size of crystallites that constitute the anatase particles is approximately 5 nm, wherein the particles themselves are bigger, somewhere between 40 to 60 nm. The subject of the invention is also a manner of stabilising the acidic suspension of nanoparticles, which allows an increase in pH value without causing excessive agglomeration, which is achieved by the use of an suitable dispersant, citric acid. A further subject of the invention is a hydrothermal method, which allows re-crystallisation of polycrystalline anatase nanoparticles into a monocrystalline form under hydrothermal conditions in an autoclave at a temperature about 130 °C or more and at adequate pressure of the water vapour.
