(EXCERPTA MEDICA INC, 2003-07-15)
-
(American Chemical Society, 1997)In recent papers we defined a theoretical frame aimed at characterizing the hardness and potential energy profiles along a reduced reaction coordinate (omega) varying from 0 to 1. In this paper we generalize that model to ...
-
(Elsevier, 2020)Some minor constituents of honey samples were determined through a fluorometric-chemical characterization method and related multifactorially with their antibacterial activity against Staphylococcus aureus and Pseudomonas ...
-
(2012)Background Ventricular dyssynchrony is a common finding in patients with heart failure (HF), especially in the presence of conduction delays. The loss of ventricular synchrony leads to progressive impairment of contractile ...
-
(MOLECULAR DIVERSITY PRESERVATION INTERNATIONAL, 2005-09)The relationship between the herbicidal activity of a number of novel 1,2,5- oxadiazole N-oxides and some physicochemical properties potentially related with this bioactivity, such as polarity, molecular volume, proton ...
-
(1995)The metabolites that mediate coronary reactive hyperemia have not been definitely identified. Although adenosine and endothelium derived substances seem to be involved, their relative contributions have not been defined ...
-
(KLUWER ACADEMIC/PLENUM PUBL, 2003-02)Purpose. To evaluate the reaction of a large series of pharmacologically significant 1,4-dihydropyridine (1,4-DHP) compounds with superoxide (O-2(.-)) in dimethylsulfoxide using differential pulse voltammetry and controlled ...
-
(Institute of Food Technologists, 2015)Gallic acid (GA) was encapsulated with native (NIn), cross-linked (CIn) and acetylated (AIn) inulin by spray-drying. Inulin microparticles were characterized by encapsulation efficiency (EE) and their release profile in ...
-
(Elsevier Ltd, 2014)Quercetin (Q), naringenin (N) and epicatechin (E) were encapsulated with inulin (In) as encapsulating agent and Capsul (C) as channelizing agent by spray drying and applying a Box-Behnken design. Q-In, N-In, E-In, Q-In-C, ...
-
(1998)The cationic dye Methylene Blue included in the internal aqueous microphase of dioctadecyldimethylammonium chloride (DODAC) vesicle shows the typical monomer–dimer equilibrium observed in homogenous aqueous solutions. ...
-
(2001)We investigated the possibility that norepinephrine from the human ovary is released after nerve stimulation and that this neurotransmitter is coupled to a steroidogenic response. Biologically significant levels of both ...
-
(Springer, 2017)The bioavailability of polychlorinated biphenyls (PCBs) in soils amended with biosolids was estimated using an aqueous leaching process of the compounds combined with rotating disk sorptive extraction (RDSE), and compared ...
-
(Frontiers Media, 2016)The social amoeba Dictyostelium discoideum has proven to be a useful model for studying relevant aspects of the host-pathogen interaction. In this work, D. discoideum was used as a model to study the ability of Salmonella ...
-
(Elsevier, 2013)In the present work we synthesized a series of hydroxy-3-arylcoumarins (compounds 1–9), some of them previously described as MAO-B selective inhibitors, with the aim of evaluating their antioxidant properties. Theoretical ...
-
(LIBRAPHARM, 2006-09)Objective: To summarize remission rates and dropouts due to adverse drug reactions (ADRs) or lack of efficacy (LoE) of serotonin-norepinephrine reuptake inhibitors (SNRIs), selective serotonin-reuptake inhibitors (SSRIs), ...
-
(Elsevier, 2013)Diels–Alder cycloaddition of 8,8-dimethylnaphthalene-1,4,5(8H)-trione with diastereomeric hydroxysulfinyldienes proceeded with high yields and good p-facial and regioselectivities. The hydroxysulfoxide moiety controls ...
-
(TAYLOR & FRANCIS INC, 2008)Grainless stalk of corn (GLSC) was tested for removal of Cr(VI) and Cr(III) from aqueous solution at different pH, contact time, temperature, and chromium/adsorbent ratio. The results show that the optimum pH for removal ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-06)This is a communication on the removal of copper(II) ions from a residual mine water using an emulsified liquid membrane (ELM). The membrane was prepared by dissolving the extractant LIX-860 (a salicylaldoxime), used as a ...
-
(1991)A simple device for an efficient waste water treatment is described. The procedure uses a massive microalga culture as a source of OH-, which increases the pH of the medium killing the bacterial population. In the device ...
