PMID: 25520698
Front Neurol. 2014 Dec 01;5:250. doi: 10.3389/fneur.2014.00250. eCollection 2014.

Multiple sclerosis (MS) is a complex debilitating disease of the central nervous system (CNS) perceived to result from the autoimmune effect of T cells in damaging myelin sheath. However, the exact pathogenesis of the disease remains elusive. Initial studies...

Rapid neodymium release to marine waters from lithogenic sediments in the Amazon estuary.

Nature communications

Rousseau TC, Sonke JE, Chmeleff J, van Beek P, Souhaut M, Boaventura G, Seyler P, Jeandel C.
PMID: 26158849
Nat Commun. 2015 Jul 09;6:7592. doi: 10.1038/ncomms8592.

Rare earth element (REE) concentrations and neodymium isotopic composition (ɛNd) are tracers for ocean circulation and biogeochemistry. Although models suggest that REE release from lithogenic sediment in river discharge may dominate all other REE inputs to the oceans, the...

PMID: 18601159
Biotechnol Bioeng. 1992 Aug;40(5):625-33. doi: 10.1002/bit.260400510.

A fluidized-bed biofilm reactor using activated carbon particles of 1.69 mm diameter as the support for biomass growth and molasses as the carbon source is used for wastewater denitrification.The start-up of the reactor was successfully achieved in 1 week...

Micro-pumping flow system for spectrophotometric determination of anionic surfactants in water.

Analytical and bioanalytical chemistry

Lavorante AF, Morales-Rubio A, de la Guardia M, Reis BF.
PMID: 15761737
Anal Bioanal Chem. 2005 Mar;381(6):1305-9. doi: 10.1007/s00216-004-3029-8. Epub 2005 Mar 11.

A novel procedure has been developed for spectrophotometric determination of anionic surfactants in water using a solenoid micro-pump as fluid-propulsion device. The proposed method is based on substitution of methyl orange (MO) by anionic surfactants in the formation of...

An environmental friendly procedure for photometric determination of hypochlorite in tap water employing a miniaturized multicommuted flow analysis setup.

Journal of automated methods & management in chemistry

Borges SS, Reis BF.
PMID: 21747732
J Autom Methods Manag Chem. 2011;2011:463286. doi: 10.1155/2011/463286. Epub 2011 May 05.

A photometric procedure for the determination of ClO(-) in tap water employing a miniaturized multicommuted flow analysis setup and an LED-based photometer is described. The analytical procedure was implemented using leucocrystal violet (LCV; 4,4',4''-methylidynetris (N,N-dimethylaniline), C(25)H(31)N(3)) as a chromogenic...

New insights into the early biochemical activation of jasmonic acid biosynthesis in leaves.

Plant signaling & behavior

Bonaventure G, Baldwin IT.
PMID: 20037473
Plant Signal Behav. 2010 Mar;5(3):287-9. doi: 10.4161/psb.5.3.10713. Epub 2010 Mar 19.

In plants, herbivore attack elicits the rapid accumulation of jasmonic acid (JA) which results from the activation of constitutively expressed biosynthetic enzymes. The molecular mechanisms controlling the activation of JA biosynthesis remain largely unknown however new research has elucidated...

Functional properties of hemoglobin immobilized in coacervates prepared from gelatin A and polyanionic carbohydrates.

Biotechnology and bioengineering

Brouwer M, Cashon R, Bonaventura J.
PMID: 18592584
Biotechnol Bioeng. 1990 Apr 05;35(8):831-6. doi: 10.1002/bit.260350811.

Complex coacervation is a phenomenon of phase separation that may occur in a solution of positively and negatively charged polyions. The resulting two phases are distinguished by the total concentration of both polyions, with the concentrated phase often containing...

Downscaling a multicommuted flow injection analysis system for the photometric determination of iodate in table salt.

Analytica chimica acta

Borges SS, Peixoto Jde S, Feres MA, Reis BF.
PMID: 20457294
Anal Chim Acta. 2010 May 23;668(1):3-7. doi: 10.1016/j.aca.2010.03.005. Epub 2010 Mar 15.

In this work a downscaled multicommuted flow injection analysis setup for photometric determination is described. The setup consists of a flow system module and a LED based photometer, with a total internal volume of about 170 microL. The system...
