A comparative proteomic study of white and black glutinous rice leaves Electron. J. Biotechnol.
Phonsakhan,Wipada; Kong-Ngern,Kanlaya.
Background Black glutinous rice contains remarkable levels of anthocyanins, which possess anti-oxidative properties and thus have health benefits. The accumulation of anthocyanins in grains of thirty black glutinous rice varieties was measured, and the results revealed that the accumulated anthocyanin content ranged from 0.262 to 2.539 mg/g. Black glutinous rice Br no. 19 was selected, and its leaf protein expression profile was compared with that of white glutinous rice RD 6 using 2D-PAGE, and the protein spots were then directly analyzed after proteolysis by LC-MS/MS. Results The proteins from the leaves of the two rice varieties were separated using 2D-PAGE and silver stained, and the spots were analyzed using Image Master 2D Platinum version 5...

BMAA et cyanotoxines : microalgues productrices et niveaux d’accumulation dans les organismes marins ArchiMer
Reveillon, Damien.
BMAA (â-N-methylamino-L-alanine) is a non proteinogenic neurotoxic amino acid that has been associated with amyotrophic lateral sclerosis. Its analytical detection is widely debated thus the global production of BMAA by cyanobacteria is questioned. We first aimed at developing an analytical method allowing for highly selective identification of BMAA and isomers, using HILIC chromatography coupled to mass spectrometry. Then, we have cultivated and analyzed more than 50 microalgae (e.g. cyanobacteria, diatoms). Unlike DAB, one of its natural isomer, BMAA was only reported in five diatom species and cannot be accounted as a cyanotoxin anymore. In parallel, we have evaluated the presence of BMAA on the three French coasts. The presence of BMAA in different...

Combined oral toxicity of azaspiracid-1 and yessotoxin in female NMRI mice ArchiMer
Aasen, John A. B.; Espenes, Arild; Miles, Christopher O.; Samdal, Ingunn A.; Hess, Philipp; Aune, Tore.
For many years, the presence of yessotoxins (YTXs) in shellfish has contributed to the outcome of the traditional mouse bioassay and has on many occasions caused closure of shellfisheries. Since YTXs do not appear to cause diarrhoea in man and exert low oral toxicity in animal experiments, it has been suggested that they should be removed from regulation. Before doing so, it is important to determine whether the oral toxicity of YTXs is enhanced when present together with shellfish toxins known to cause damage to the gastrointestinal tract. Consequently, mice were given high doses of YTX, at 1 or 5 mg/kg body weight, either alone or together with azaspiracid-1 (AZA1) at 200 μg/kg. The latter has been shown to induce damage to the small intestine at this...

Comparison of High Performance Liquid Chromatography with Fluorescence Detector and with Tandem Mass Spectrometry methods for detection and quantification of Ochratoxin A in green and roasted coffee beans BABT
Bandeira,Raquel Duarte da Costa Cunha; Uekane,Thais Matsue; Cunha,Carolina Passos da; Rodrigues,Janaina Marques; la Cruz,Marcus Henrique Campino de; Godoy,Ronoel Luiz de Oliveira; Fioravante,Andreia de Lima.
Two analytical methods for the determination and confirmation of ochratoxin A (OTA) in green and roasted coffee samples were compared. Sample extraction and clean-up were based on liquid-liquid phase extraction and immunoaffinity column. The detection of OTA was carried out with the high performance liquid chromatography (HPLC) combined either with fluorescence detection (FLD), or positive electrospray ionization (ESI+) coupled with tandem mass spectrometry (MS-MS). The results obtained with the LC-ESI-MS/MS were specific and more sensitive, with the advantages in terms of unambiguous analyte identification, when compared with the HPLC-FLD.

Complex Toxin Profile of French Mediterranean Ostreopsis cf. ovata Strains, Seafood Accumulation and Ovatoxins Prepurification ArchiMer
Brissard, Charline; Herrenknecht, Christine; Sechet, Veronique; Herve, Fabienne; Pisapia, Francesco; Harcouet, Jocelyn; Lemee, Rodolphe; Chomerat, Nicolas; Hess, Philipp; Amzil, Zouher.
Ostreopsis cf. ovata produces palytoxin analogues including ovatoxins (OVTXs) and a putative palytoxin (p-PLTX), which can accumulate in marine organisms and may possibly lead to food intoxication. However, purified ovatoxins are not widely available and their toxicities are still unknown. The aim of this study was to improve understanding of the ecophysiology of Ostreopsis cf. ovata and its toxin production as well as to optimize the purification process for ovatoxin. During Ostreopsis blooms in 2011 and 2012 in Villefranche-sur-Mer (France, NW Mediterranean Sea), microalgae epiphytic cells and marine organisms were collected and analyzed both by LC-MS/MS and hemolysis assay. Results obtained with these two methods were comparable, suggesting ovatoxins...

Desenvolvimento e validação de método para determinação de florfenicol e seu metabólito em tilápia por LC-MS/MS. Repositório Alice
SHIROMA, L. S.; JONSSON, C. M.; QUEIROZ, S. C. do N. de; BOTTOLI, C. B. G..
Atualmente há um crescimento na produção de pescado no mundo devido à busca dos consumidores por alimentos mais saudáveis e com alto valor nutritivo.1 Para atender a esse aumento na demanda de pescados surgiu o cultivo intensivo. Porém neste sistema de produção há uma maior ocorrência de infecções, pois a alta densidade populacional de peixes resulta em má qualidade da água, mudanças nos valores de pH, oxigênio, maior acúmulo de resíduos orgânicos e nutrição insuficiente dos peixes. Essas infecções podem ocasionar lesões superficiais, nas barbatanas, nas caudas e doenças branquiais.2 Para controlar isso, são administrados antibióticos, que são compostos que previnem ou tratam infecções microbianas. Entretanto o uso indiscriminado dessas substâncias pode...

FERRACINI, V. L.; QUEIROZ, S. C. do N. de; ROSA, M. A.; LOPES, P. R. C..
Paclobutrazol (PBZ) é um regulador de crescimento que tem sido utilizado para alterar o ciclo fenológico da mangueira visando a produção de frutos em qualquer época do ano. É bastante utilizado na região nordeste do Brasil e a determinação dos resíduos na fruta é importante pois há pouco conhecimen- to sobre o acúmulo desta substância na planta em condições brasileiras. Para isso foi necessário adaptar um método analítico para determinar resídu- os de paclobutrazol em frutos de manga. Após a extração do PBZ na matriz o extrato foi analisado por LC-MS/MS. Os limites de detecção (LOD) e de quantificação (LOQ) obtidos para o PBZ foram de 0,25 ?g Kg-1 e 1,25 ?g Kg-1, respectivamente. As recuperações foram de 82 a 94% e se encontram dentro da faixa considerada...

Determination of moxidectin in serum by liquid chromatography-tandem mass spectrometry and its application in pharmacokinetic study in lambs. Repositório Alice
BAPTISTA, R. C.; FERNANDES, M. A. M.; GILAVERTE, S.; QUEIROZ, S. C. do N. de; ASSALIN, M. R.; FERRACINI, V. L.; MONTEIRO, A. L. G.; REYES, F. G. R..
Abstract: The widespread use of moxidectin (MOX), a parasiticide used in the sheep breeding, has induced the parasite resistance in Brazilian farms. As a consequence, the farmers often increase the dose and frequency of drug utilization, and disregards safety of meat or milk. In order to establish adequate therapeutic treatment it is necessary to know the pharmacokinetics of the drug in the animal's body. Thus, high performance liquid chromatography-electrospray ionization-tandem mass spectrometry (HPLC-ESI-MS/MS) method was developed for the determination of MOX in serum lamb. Serum samples were treated with acetonitrile to precipitate proteins. A clean up by dispersive extraction in solid phase (SPE-d), using primary/secondary amine (PSA) and C18...

Dissolved azaspiracids are absorbed and metabolized by blue mussels (Mytilus edulis) ArchiMer
Jauffrais, Thierry; Kilcoyne, Jane; Herrenknecht, Christine; Truquet, Philippe; Sechet, Veronique; Miles, Christopher O.; Hess, Philipp.
The relationship between azaspiracid shellfish poisoning and a small dinoflagellate, Azadinium spinosum, has been shown recently. The organism produces AZA1 and -2, while AZA3 and other analogues are metabolic products formed in shellfish. We evaluated whether mussels were capable of accumulating dissolved AZA1 and -2, and compared the toxin profiles of these mussels at 24 h with profiles of those exposed to live or lysed A. spinosum. We also assessed the possibility of preparative production of AZA metabolites by exposing mussels to semi-purified AZA1. We exposed mussels to similar concentration of AZAs: dissolved AZA1+2 (crude extract) at 7.5 and 0.75 µg L-1, dissolved AZA1+2 (7.5 µg L-1) in combination with Isochrysis affinis galbana, and lysed and live...

Jauffrais, Thierry.
This study has been conducted in order to develop the analysis of AZAs and to produce AZAs from A. spinosum culture. It also aimed at studying the effect of environmental and nutritional factors on growth and toxin production. The study also demonstrated a link between A. spinosum and the accumulation of AZAs in shellfish, followed by the clarification of the processes of accumulation, detoxification and biotransformation of AZAs into mussels. A quantitative analysis of AZAs in A. spinosum cultures was developed, and the formation and structure of the AZA methylated analogues was explained and minimised. This work also demonstrated the feasibility of a sustainable production of AZAs from A. spinosum culture and highlighted the main factors influencing...

Effect of Dilution Rate on Azadinium spinosum and Azaspiracid (AZA) Production in Pilot Scale Photobioreactors for the Harvest of AZA1 and -2 ArchiMer
Jauffrais, Thierry; Sechet, Veronique; Truquet, Philippe; Amzil, Zouher; Herrenknecht, Christine; Hess, Philipp.
Azadinium spinosum, a small dinoflagellate has recently been discovered and identified as the primary producer of azaspiracid-1 (AZA) and -2. Since AZA poisoning has been reported following consumption of contaminated shellfish it is important to have these toxins available for toxicological studies, and a sustainable production of AZAs as calibrants in monitoring programs without having to rely on natural events. In order to address this concern, continuous pilot scale cultures were carried out to evaluate the feasibility of AZA production from A. spinosum. Algae were cultured using two 100 L chemostats in series (R1 and R2), with agitation and pH control. Four different dilution rates were tested (0.15, 0.2, 0.25 and 0.3 day−1) to evaluate chemostat...

Roue, Melanie; Darius, Helene Taiana; Picot, Sandy; Ung, Andre; Viallon, Jerome; Gaertner-mazouni, Nabila; Sibat, Manoella; Amzil, Zouher; Chinain, Mireille.
Ciguatera Fish Poisoning (CFP) is a foodborne disease classically related to the consumption of tropical coral reef fishes contaminated with ciguatoxins (CTXs), neurotoxins produced by dinoflagellates of the Gambierdiscus genus. Severe atypical ciguatera-like incidents involving giant clams, a marine resource highly consumed in the South Pacific, are also frequently reported in many Pacific Islands Countries and Territories. The present study was designed to assess the ability of giant clams to accumulate CTXs in their tissues and highlight the potential health risks associated with their consumption. Since giant clams are likely to be exposed to both free-swimming Gambierdiscus cells and dissolved CTXs in natural environment, ex situ contamination...

Guideline values and human risk assessment for the presence of anti-inflammatory drugs remaining in drinking water after lab scale treatment BJPS
Pais,Mariana Castello Novo; Nascimento,Elizabeth de Souza.
Abstract This study aimed to determine whether the anti-inflammatory drugs that are most commonly consumed in Brazil, including diclofenac, ketoprofen, naproxen, indomethacin, ibuprofen and acetaminophen, are present in drinking water and to derive guideline values to characterize the human risk. These pharmaceuticals were quantified in surface waters by LC-MS/MS with solid phase extraction, both before and after conventional treatment on a laboratory scale, using a jar test assay. The methods used to quantify these drugs showed good results: the chromatographic analysis obtained correlation coefficients between 0.9952 and 0.9991, with limits of quantification of 0.5 ng.mL-1 - 50 ng.mL-1 and precision standard deviations (0.08 - 2.08). Only ketoprofen and...
