Abstract
A confirmatory method for the determination of polypeptide antibiotics (bacitracin, colistin, and polymyxin B) in muscle samples has been developed. Extraction is performed with acidified methanol, and a clean-up step by solid-phase extraction with polymeric cartridges is applied. Separation by ultra-high performance liquid chromatography (UHPLC) is carried out using a solid core C18 column and gradient elution with water/acetonitrile containing 0.2% formic acid. High-resolution mass spectrometry (HRMS) (Q-Orbitrap) detection using different working modes has proved to be highly advantageous in eliminating interfering signals from endogenous matrix components. The analytical method has been successfully validated according to Commission Regulation 2021/808/EU and is currently used in a public health laboratory involved in veterinary medicines residue surveillance activities.

Abstract
Agrifood industries generate large amounts of waste that may result in remarkable environmental problems, such as soil and water contamination. Therefore, proper waste management and treatment have become an environmental, economic, and social challenge. Most of these wastes are exceptionally rich in bioactive compounds (e.g., polyphenols) with potential applications in the food, cosmetic, and pharmaceutical industries. Indeed, the recovery of polyphenols from agrifood waste is an example of circular bioeconomy, which contributes to the valorization of waste while providing solutions to environmental problems. In this context, unconventional extraction techniques at the industrial scale, such as microwave-assisted extraction (MAE), which has demonstrated its efficacy at the laboratory level for analytical purposes, have been suggested to search for more efficient recovery procedures. On the other hand, natural deep eutectic solvents (NADES) have been proposed as an efficient and green alternative to typical extraction solvents. This review aims to provide comprehensive insights regarding the extraction of phenolic compounds from agrifood waste. Specifically, it focuses on the utilization of MAE in conjunction with NADES. Moreover, this review delves into the possibilities of recycling and reusing NADES for a more sustainable and cost-efficient industrial application. The results obtained with the MAE-NADES approach show its high extraction efficiency while contributing to green practices in the field of natural product extraction. However, further research is necessary to improve our understanding of these extraction strategies, optimize product yields, and reduce overall costs, to facilitate the scaling-up.

Abstract
Agri-food industries generate a large amount of waste that offers great revalorization opportunities within the circular economy framework. In recent years, new methodologies for the extraction of compounds with more eco-friendly solvents have been developed, such as the case of natural deep eutectic solvents (NADES). In this study, a methodology for extracting phenolic compounds from olive tree leaves using NADES has been optimized. The conditions established as the optimal rely on a solvent composed of choline chloride and glycerol at a molar ratio of 1:5 with 30% water. The extraction was carried out at 80 °C for 2 h with constant agitation. The extracts obtained have been analyzed by high-performance liquid chromatography coupled to tandem mass spectrometry (HPLC-MS/MS) in MRM mode. The comparison with conventional ethanol/water extraction has shown that NADES, a more environmentally friendly alternative, has improved extraction efficiency. The main polyphenols identified in the NADES extract were Luteolin-7-O-glucoside, Oleuropein, 3-Hydroxytyrosol, Rutin, and Luteolin at the concentrations of 262, 173, 129, 34, and 29 mg kg-1 fresh weight, respectively.

Abstract
Winery wastes are rich in polyphenols with high added value to be used in cosmetics, pharmaceuticals, and food products. This work aims at recovering and purifying the polyphenolic fraction occurring in the malolactic fermentation lees generated during the production of Albariño wines. Phenolic acids, flavonoids, and related compounds were recovered from this oenological waste by green liquid extraction using water as the solvent. The resulting extract solution was microfiltered to remove microparticles and further treated by ultrafiltration (UF) using membranes of 30 kDa and 5 kDa molecular weight cut-offs (MWCOs). The feed sample and the filtrate and retentate solutions from each membrane system were analyzed by reversed-phase liquid chromatography (HPLC) with UV and mass spectrometric (MS) detection. The most abundant polyphenols in the extracts were identified and quantified, namely: caftaric acid with a concentration of 200 µg g-1 and trans-coutaric acid, cis-coutaric acid, gallic acid, and astilbin with concentrations between 15 and 40 µg g-1. Other minor phenolic acids and flavanols were also found. The UF process using the 30 kDa membrane did not modify the extract composition, but filtration through the 5 kDa poly-acrylonitrile membrane elicited a decrease in polyphenolic content. Hence, the 30 kDa membrane was recommended to further pre-process the extracts. The combined extraction and purification process presented here is environmentally friendly and demonstrates that malolactic fermentation lees of Albariño wines are a valuable source of phenolic compounds, especially phenolic acids.

Abstract
The aim of this study was to evaluate the recovery of phenolic compounds from olive mill and winery wastes by conventional solid-liquid extraction (SLE) using water as the extraction solvent. The studied variables were extraction time (5-15 min), temperature (25-90 °C), solid-to-liquid ratio (1:10-1:100 (kg/L)), pH (3-10) and application of multiple extractions (1-3). The extraction efficiency was evaluated in terms of total phenolic content (TPC), determined by high performance liquid chromatography (HPLC-UV), but also from the recovery of some representative phenolic compounds. The optimized conditions were one extraction step, 10 min, 25 °C, 1:30 (kg/L), pH 5 for olive pomace, and one extraction step, 10 min, 70 °C, 1:100 (kg/L), pH 5 for winery residues. The extraction method is simple and suitable for scaling-up in industry, and the aqueous extracts are fully compatible with further purification schemes based on the use of membranes or resins. The optimized technique was applied to a set of different representative residues from olive mill and winery industries, to assess their suitability as sources for phenolic compounds recovery. The phenolic content in the extracts was evaluated by chromatographic analysis and by the Folin-Ciocalteu assay (FC). Furthermore, the antioxidant capacity was determined by 2,2-azinobis-3-etilbenzotiazolina-6-sulfonat (ABTS), 2,-diphenyl-1-picrylhydrazyl (DPPH) and ferric reducing antioxidant power (FRAP) assays. Because of their high contents in phenolic compounds and great antioxidant capacity, olive pomace and lees filters were identified as especially suited sources for phenolic compounds recovery.

Abstract
Spinach and orange by-products are well recognized for their health benefits due to the presence of natural polyphenols with antioxidant activity. Therefore, the demand to produce functional products containing polyphenols recovered from vegetables and fruits has increased in the last decade. This work aims to use the integrated membrane process for the recovery of polyphenols from spinach and orange wastes, implemented on a laboratory scale. The clarification (microfiltration and ultrafiltration, i.e., MF and UF), pre-concentration (nanofiltration, NF), and concentration (reverse osmosis, RO) of the spinach and orange extracts were performed using membrane technology. Membrane experiments were carried out by collecting 1 mL of the permeate stream after increasing the flow rate in 1 mL/min steps. The separation and concentration factors were determined by HPLC-DAD in terms of total polyphenol content and by polyphenol families: hydroxybenzoic acids, hydroxycinnamic acids, and flavonoids. The results show that the transmembrane flux depended on the feed flow rate for MF, UF, NF, and RO techniques. For the spinach and orange matrices, MF (0.22 µm) could be used to remove suspended solids; UF membranes (30 kDa) for clarification; NF membranes (TFCS) to pre-concentrate; and RO membranes (XLE for spinach and BW30 for orange) to concentrate. A treatment sequence is proposed for the two extracts using a selective membrane train (UF, NF, and RO) to obtain polyphenol-rich streams for food, pharmaceutical, and cosmetic applications, and also to recover clean water streams.

Abstract
Winery and olive mill industries generate large amounts of wastes causing important environmental problems. The main aim of this work is the evaluation of different membrane separation processes like microfiltration, ultrafiltration, nanofiltration, and reverse osmosis for the recovery of polyphenols from winery and olive mill wastes in aqueous solutions. Membrane processes were tested separately in a closed-loop system, and by an integration in a concentration mode sequential design (open-loop). Feed flow rate was varied from 1 to 10 mL min-1, and permeate samples were taken in order to measure the polyphenols concentration. The separation and concentration efficiency were evaluated in terms of total polyphenol content, and by polyphenols families (hydroxybenzoic acids (HB), hydroxycinnamic acids (HC), and flavonoids (F)), using high performance liquid chromatography. Results showed that MF and UF membranes removed suspended solids and colloids from the extracts. NF was useful for polyphenols separation (HB rejections were lower than for HC and F: HB rejections of 50 and 63% for lees filters and olive pomace extracts, respectively), and RO membranes were able to concentrate polyphenols streams (86 and 95% rejection from lees filters and olive pomace, respectively). Membranes sequential designs for lees filters and olive pomace extracts, using a selective membrane train composed by UF, NF and RO membranes, were able to obtain polyphenol rich streams and high-quality water streams for reuse purposes.

Abstract
More sustainable waste management in the winery and olive oil industries has become a major challenge. Therefore, waste valorization to obtain value-added products (e.g., polyphenols) is an efficient alternative that contributes to circular approaches and sustainable environmental protection. In this work, an integration scheme was purposed based on sustainable extraction and membrane separation processes, such as nanofiltration (NF) and reverse osmosis (RO), for the recovery of polyphenols from winery and olive mill wastes. Membrane processes were evaluated in a closed-loop system and with a flat-sheet membrane configuration (NF270, NF90, and Duracid as NF membranes, and BW30LE as RO membrane). The separation and concentration efficiency were evaluated in terms of the total polyphenol content (TPC), and by polyphenol families (hydroxybenzoic acids, hydroxycinnamic acids, and flavonoids), using high-performance liquid chromatography. The water trans-membrane flux was dependent on the trans-membrane pressure for the NF and RO processes. NF90 membrane rejected around 91% of TPC for the lees filters extracts while NF270 membrane rejected about 99% of TPC for the olive pomace extracts. Otherwise, RO membranes rejected more than 99.9% of TPC for both types of agri-food wastes. Hence, NF and RO techniques could be used to obtain polyphenol-rich streams, and clean water for reuse purposes.

Abstract
Acidic mine Drainage (AMD) is still considered one of the greatest mining sustainability challenges due to the large volumes of wastes generated and the high associated treatment cost. New regulation initiatives on sustainable development, circular economy and the need for strategic elements as Rare Earth Elements (REE) may overcome the traditional research initiatives directed to developing low cost treatment options and to develop research initiatives to identify the potential benefit of considering such AMD as a potential secondary resource. As an example, this study develops the integration of a three-stage process where REE are selectively separated from base metals (e.g. Fe, Al, Mn, Ca, Mg, Cd, Pb) and then concentrate to produce a rich REE by-product recovered as REE-phosphates. Selective separation of Fe (>99%) was achieved by total oxidation to Fe(III) and subsequent precipitation as schwertmannite at pH 3,6 ± 0.2. REE were then extracted from AMD using a sulfonic ion-exchange resin to produce concentrated REE sulfuric solutions up to 0.25 gREE/L. In a final stage selective separation of REE from Al(III), Ca(II) and Mg(II) and transitions elements (Cu, Zn, Ni) was achieved by precipitation with phosphate solutions under optimized pH control and total phosphate concentration. XRD analysis identified low-crystalline minerals. By using a thermal treatment the presence of PrPO4(s) and Cheralite (CePO4(s)) where Ce is substituted by La and Ca and Xenotime (YPO4(s)) were found as main minerals AlPO4(s) Ca,MgYPO4(s) were also identified.

Abstract
The production of olive oil and wine are two of the main agri-food economic activities in Southern Europe. They generate large amounts of solid and liquid wastes (e.g., olive pomace, olive mill wastewater, grape pomace, grape stems, wine lees, and wine processing wastewater) that represent a major environmental problem. Consequently, the management of these residues has become a big challenge for these industries, since they are harmful to the environment but rich in bioactive compounds, such as polyphenols. In recent years, the recovery of phenolic compounds has been proposed as a smart strategy for the valorization of these by-products, from a circular economy perspective. This review aims to provide a comprehensive description of the state of the art of techniques available for the analysis, extraction, and purification of polyphenols from the olive mill and winery residues. Thus, the integration and implementation of these techniques could provide a sustainable solution to the olive oil and winery sectors.

Abstract
Fruits, vegetables, spices, and herbs are a potential source of phenolic acids and polyphenols. These compounds are known as natural by-products or secondary metabolites of plants, which are present in the daily diet and provide important benefits to the human body such as antioxidant, anti-inflammatory, anticancer, anti-allergic, antihypertensive and antiviral properties, among others. Plentiful evidence has been provided on the great potential of polyphenols against different viruses that cause widespread health problems. As a result, this review focuses on the potential antiviral properties of some polyphenols and their action mechanism against various types of viruses such as coronaviruses, influenza, herpes simplex, dengue fever, and rotavirus, among others. Also, it is important to highlight the relationship between antiviral and antioxidant activities that can contribute to the protection of cells and tissues of the human body. The wide variety of action mechanisms of antiviral agents, such as polyphenols, against viral infections could be applied as a treatment or prevention strategy; but at the same time, antiviral polyphenols could be used to produce natural antiviral drugs. A recent example of an antiviral polyphenol application deals with the use of hesperidin extracted from Citrus sinensis. The action mechanism of hesperidin relies on its binding to the key entry or spike protein of SARS-CoV-2. Finally, the extraction, purification and recovery of polyphenols with potential antiviral activity, which are essential for virus replication and infection without side-effects, have been critically reviewed.

Abstract
Phenolic compounds recovery by mechanical stirring extraction (MSE) was studied from orange and spinach wastes using water as a solvent. The statistical analysis showed that the highest total polyphenol content (TPC) yield was obtained using 15 min, 70 °C, 1:100 (w/v) solid/solvent ratio and pH 4 for orange; and 5 min, 50 °C, 1:50 (w/v) solid/solvent ratio and pH 6 for spinach. Under these conditions, the TPC was 1 mg gallic acid equivalent (GAE) g-1 fresh weight (fw) and 0.8 mg GAE g-1 fw for orange and spinach, respectively. MSE substantially increased the phenolic compounds yields (1-fold for orange and 2-fold for spinach) compared with ultrasound-assisted extraction. Furthermore, the antioxidant activity of orange and spinach extracts was evaluated using DPPH, FRAP and ABTS. The obtained results pointed out that the evaluated orange and spinach residues provided extracts with antioxidant activity (2.27 mg TE g-1 and 0.04 mg TE g-1, respectively).

Abstract
RESUMO Porções de íleo terminal foram coletados de 100 suínos com sinais de doença gastrointestinal na área metropolitana de Bucaramanga, a fim de se estudar a eficiência do diagnóstico de enteropatia proliferativa suína (PPE) pela técnica de PCR aninha (PCRa) empregando sequências específicas (primers) para L. intracellularis: 16S ARN região (270pb) e sua correlação com achados clínicos e patológicos. Todas as amostras foram processadas para se determinar a associação entre positividade por PCR, os sinais clínicos, os achados de necropsia e as lesões histológicas. Cinquenta e seis por cento das amostras foram positivas para L. intracellularis pela PCRa. Só 2% exibiram resultados positivos pela técnica Warthin-Starry. Trinta e um de 100 animais com sinais de anorexia resultaram positivos para PCRa (P>0,05). Não houve associação (P<0,05) entre diarreia e queda no crescimento, bem como associação (P<0,05) entre achados anatomopatológicos e histológicos com PCRa positivas.

Abstract
Commercial hardwood biochars ranging in N2 specific surface area of 0.1-427 m(2) · g(-1) were added to an agricultural soil at 0, 1, or 2% levels to determine whether they would predictably reduce the pore water concentration of sulfamethazine (SMT). The soil and biochar-soil mixtures were preweathered under mild (2 d, 20 °C) or more severe (28 d, 40 °C) conditions before spiking. The carbon-normalized biochar-water distribution coefficient (KBC) of the biochars varied by a factor of up to 10(4), depending on biochar properties and SMT concentration. Except for the fast-pyrolysis biochar, KBC greatly exceeded the soil organic carbon-water distribution coefficient KOC. Sorption in the mixtures increased as expected with biochar and dose. However, sorption was dramatically overpredicted (by up to 10(2.5)) by the sum of sorption to the individual components, indicating a strong weathering effect even under the mild conditions. The soil-subtracted weathered biochar-water isotherms were more linear, and the KBC values approached or lay within the range of KOC values reported for SMT in 19 soils. Biochars both in intimate contact with soil and placed in a membrane bag suspended in the solution showed reduced N2-B.E.T. surface area after weathering, implicating fouling of the biochar surface by humic substances transferred through water. The results indicate that only highly surfaceous, carbonaceous biochars would be useful for stabilizing soil contaminated with compounds such as SMT. They also suggest that weathering may attenuate the contribution of native (environmental) black carbon to sorption of such compounds in soils and sediments.

Abstract
An analytical method for determination and confirmation of nine coccidiostatics in eggs is reported. Ethyl acetate is used as extraction solvent, with satisfactory results, and simple automated clean-up is based on gel-permeation chromatography (GPC) . The target compounds are then analysed by liquid chromatography-electrospray ionization-tandem mass spectrometry. The method was validated in-house in accordance with Commission Decision 2002/657/EC. Trueness and precision were determined at four concentrations, and the mean errors obtained were <10 %, with relative standard deviations ranging from 3 to 18 %. For three non-authorized coccidiostatics (clopidol, ethopabate, and ronizadole), decision limit and detection capability were in the ranges 0.12-0.16 and 0.18-0.23 μg kg(-1), respectively. The results obtained prove the suitability of this new analytical method for routine monitoring of these substances in eggs.

Abstract
Residues of tetracyclines reach soils as a result of animal waste application. Sorption is a key process in transport, fate, and effects of contaminants in the environment. In this work, we have attempted to predict the sorption of four widely used tetracyclines (oxytetracycline, tetracycline, chlortetracycline, and doxycycline) from soil physicochemical properties. Batch sorption experiments were performed on 15 natural soils with a broad range of physicochemical properties, and the data were fitted to several isotherm models. Multivariate analysis methods were conducted to identify the main factors affecting the sorption distribution coefficients (K (d)) of the tetracyclines at two aqueous concentration levels (100 and 400 μg L(-1)). All four tetracycline sorption isotherms in alkaline and acidic soils were well described by the Freundlich and Langmuir equation, respectively. At intermediate soil pH (from 5.3 to 7), oxytetracycline and tetracycline exhibited Freundlich behavior, whereas chlortetracycline and doxycycline followed a Langmuir model. Two partial least squares (PLS) models were developed. The first one uses five soil descriptors as input variables; the second uses, pH, cation exchange capacity (CEC), and log K (d,OTC). Both models satisfactorily predicted distribution coefficients within a factor of 1.5. Sorption of tetracyclines in soil is governed by several factors, in the following order of importance: solution speciation, CEC (dominant at acidic-neutral soil pH), transition metal content, and texture. The PLS models indicated that tetracycline sorption can be predicted using a minimal set of soil descriptors including oxytetracycline sorption data.

Abstract
Adsorption of ionizable compounds by black carbon is poorly characterized. Adsorption of the veterinary antibiotic sulfamethazine (SMT; a.k.a., sulfadimidine; pK(a1) = 2.28, pK(a2) = 7.42) on a charcoal was determined as a function of concentration, pH, inorganic ions, and organic ions and molecules. SMT displayed unconventional adsorption behavior. Despite its hydrophilic nature (log K(ow) = 0.27), the distribution ratio K(d) at pH 5, where SMT(0) prevails, was as high as 10(6) L kg(-1), up to 10(4) times greater than literature reported K(oc). The K(d) decreases at high and low pH but not commensurate with the decline in K(ow) of the ionized forms. At pH 1, where SMT(+) is predominant and the surface is positive, a major driving force is π-π electron donor-acceptor interaction of the protonated aniline ring with the π-electron rich graphene surface, referred to as π(+)-π EDA, rather than ordinary electrostatic cation exchange. In the alkaline region, where SMT(-) prevails and the surface is negative, adsorption is accompanied by near-stoichiometric proton exchange with water, leading to the release of OH(-) and formation of an exceptionally strong H-bond between SMT(0) and a surface carboxylate or phenolate, classified as a negative charge-assisted H-bond, (-)CAHB. At pH 5, SMT(0) adsorption is accompanied by partial proton release and is competitive with trimethylphenylammonium ion, signifying contributions from SMT(+) and/or the zwitterion, SMT(±), which take advantage of π(+)-π EDA interaction and Coulombic attraction to deprotonated surface groups. In essence, both pK(a1) and pK(a2) increase, and SMT(±) is stabilized, in the adsorbed relative to the dissolved state.

Abstract
The extraction of six sulfonamides (sulfadiazine, sulfadimidine, sulfathiazole, sulfachloropiridazine, sulfadimethoxine, and sulfaquinoxaline) from soils with different physicochemical characteristics and at several aging times was investigated. Conventional mechanical shaking, microwave-assisted extraction, ultrasound probe-assisted extraction and pressurized liquid extraction techniques were evaluated. The four techniques provided similar results when applied to freshly contaminated soils. However, microwave-assisted extraction was the most suitable to extract sulfonamide aged residues from soils. Microwave-assisted extraction was applied to eight soils aged for 3 months, using acetonitrile:buffer pH 9 (20:80) as the extraction solvent, and recoveries ranged from 15-25% for STZ to 42-64% for SDM.

Abstract
OBJECTIVE To compare the measurements of pulmonary artery occlusion pressure (PAOP) by means of the use a pulmonary artery catheter and those obtained through a formula that relates the systolic artery pressure before and after a Valsalva maneuver. DESIGN Prospective observational study. SCOPE Medical-surgical intensive care unit. PATIENTS A total of 120 patients mechanically ventilated and with deep sedation who had pulmonary artery catheter and arterial line. INTERVENTIONS Provocation of a Valsalva maneuver by maintaining airway pressure at 30 mmHg for 10 seconds that was subsequently released. MAIN VARIABLES OF INTEREST PAOP measured at the end of expiration by means of the use of a pulmonary artery catheter, PAOP was calculated by means of the use of a formula that relates the systolic artery pressure before and after a Valsalva maneuver. RESULTS There was a limited correlation between the measured PAOP and that calculated by means of the Valsalva maneuver in the total population (r=0.44, CI 95%: 0.28 to 0.57, p=0.0001). There was a better correlation in the post-surgical subgroup (r=0.518, CI 95%: 0.1055 to 0.7738, p=0.016) and in the sub-group of "Others diagnosis" (r=0.62, CI: 95%: 0.30 to 0.81, p=0.001). CONCLUSIONS The prediction of the PAOP by means of the Valsalva maneuver showed a limited correlation with that obtained by means of the pulmonary artery catheter.

Abstract
15514 Background: In the Pignon’s meta-analysis, the OS benefit was 8% with chemoradiation in LA SCCHN. Unfortunately it is still unclear what scheme is the best, cisplatin (CDDP) being the most widely used drug. Other drugs such as gemcitabine (GMZ) has promising results, although toxicity has been severe but tolerable. We have published an initial study using GMZ and radiotherapy (ann oncol. 2004;15:301). In the present study we wished to determine if a scheme in which GMZ is alternated with CDDP and concomitant radiotherapy reduced toxicity yet maintains our previously described therapeutic effectiveness. This is a preliminary report with a short follow-up period. Methods: Inclusion criteria: patients with SCCHN (EC: III, IVa and IVb ) or with recurring disease, and no sytemic metastases or patients rejection of surgery between 03/2003 and 09/2004. Chemotherapy scheme consisted of GMZ at 100 mg/m2 once a w, ws 1, 3, 5, 7 and CDDP at 50 mg/m2 once a w, ws 2, 4, y 6. Radiotherapy consisted of 2 Gy/day, for a total of 70 Gy during the 7 ws. Toxicity evaluation focused on mucositis, xerostomia, dysphagia y leukopenia. Results: 28 patients were treated. 7 (25%)/ stage III, 11 (39.3%) IVa, 10 (35.7%) IVb. The tumor sites distribution was as follows: 9 patients with oropharynx and larynx disease (32.1%), 6 patients with oral cavity disease (21.4%), 3 patients with paranasal sinus disease (10.7%), and 1 hypopharinx (3.5%). A CCR was observed in 21 patients (75%), a partial response was observed in 5 patients (17%). Organ preservation was achieved in 68% of the patients. Toxicity: mucositis Grade 3–4 was in 42% of patients, leucopenia grade III in 29%, dysphagia in 19% and xerostomia in 10%. 40%of the patients stopped treatment for one or two weeks due to toxicity without affecting the doses of both treatments. Conclusions: The scheme with alternating GMZ and CDDP concomitant with radiotherapy is safe and effective. We observed a lower incidence in mucositis and few systemic toxic effects. Our findings support further studies in which alternating chemotherapeutic schemes are utilized given that tumor response is increased without an increment in toxicity. No significant financial relationships to disclose.

Abstract
15502 Background: Previous studies with cetuximab in SCCHN demonstrate to be clinically beneficial. In the present study we wished to evaluate the efficacy and safety of a chemotherapeutic scheme using gemcitabine, radiotherapy and cetuximab for SCCHN. Preliminary report of 20 of 40 enrolled patients into a phase II clinical trial. Methods: inclusion criteria; histological confirmation of epidermoid carcinoma, ages 18 to 70, K > 70%, normal renal, hepatic and haematologic functions, without previous treatment, surgically inoperable disease, or patients with operable disease that did not consent to surgery. All patients signed an informed consent form. Radiotherapy: 200 cGy/d/5/w until 70Gy were completed. Cetuximab: an initial dose of 400 mg/m2 one week prior to initiation of radiotherapy, followed by 250 mg/m2 weekly until completion of radiotherapy. Gemcitabine: 50 mg /m2 weeks 1–2, 4–5 and 7. Results: 20 patients were enrolled (16m/4f) from november of 2004 to november of 2005, (5 oral cavity, 5 oropharynx, 8 larynx, 1 hypopharynx and 1 paranasal sinus). Mean age 56 yrs (33–75). Tumor staging: 7/III, 8/IVa and 5/IVb. One female was excluded, 19 completed the study and were evaluated. GR 17/19 (89.5%), CR 13/17 (76.5%) and PR 4/17 (23.5%). 2/19 NR (10.5%). CR of the 1ary tumor 15/19 patients (78.9%); CR 6/11 patients with lymphatic disease at diagnosis (54.5%), PR 3/19 (27.3%). Toxicity: mucositis g/III-IV 8/19 patients; rash g/III 4 patients. 2/19 did not complete treatment with chemotherapy due to mucositis but did with radiotherapy. No relationship was found between clinical response and the severity of the rash. One patient developed leukopenia g/III. 4 patients developed disphagia g/II, one has not resolved after 8 month follow up. Xerostomia g/II was 7/19 patients. Dermatological toxicity resolved by the end of the treatment. Mean follow up: 6 months, 1 patient which did not respond died and 1 patient with a PR recurred. Conclusions: The scheme is safe and effective with tolerable toxicity. In our previously reported experience, the addition of cetuximab to gemcitabine and radiotherapy does not increment local toxicity, statistical validation of these findings require the completion of the 40 patient study. No significant financial relationships to disclose.

Abstract
A liquid chromatography-mass spectrometry (LC-MS) method was developed for the determination of five macrolides in natural water samples, using kitasamycin as surrogate. The macrolides were extracted from water samples using Oasis HLB cartridges. Pre-concentration factors up to 250 were obtained. Separation was carried out in an end-capped silica-based C18 column and mobile phases consisting of water/acetonitrile mixtures containing ammonium acetate. Detection was performed by mass spectrometry with a single quadrupole and a triple quadrupole using an electrospray interface. The quality parameters obtained with these two approaches were compared. The detection limits of the whole process were about 1 ng l(-1). The recoveries from 250 ml of water samples spiked at 25-125 ng l(-1) level were in the range 85-115%, except for azithromycin levels, which were around 70%. Erythromycin-H2O, clarithromycin and azithromyzin were found, at the sub ng l(-1) level, in the studied rivers.

Abstract
A method is reported for the determination, in water samples, of 10 quinolones which are used as veterinary drugs. Analytes are isolated from samples by solid-phase extraction (SPE) and analysed by reversed-phase high-performance liquid chromatography using fluorimetric detection. A solid-phase extraction procedure based on retention on HBL OASIS cartridges and elution with a mixture of acetonitrile-water in basic medium is suitable for pre-concentration of the analytes. Pre-concentration factors up to 250 can be obtained. The quinolones are separated with an octyl silica-based column and mobile phases consisting of aqueous oxalic acid solutions and acetonitrile mixtures. The attained detection limits of the whole process are in the ng l(-1) level when 250 ml of water sample is processed. Recovery rates, from natural water samples spiked at 2060 ng l(-1) level, range from 70 to 100% and common standard deviation are about 6-12%.

Abstract
The Raipore R1030 membrane, an anion-exchange membrane containing ammonium groups as ionogenic groups, was evaluated as the interface of an optical sensor for Cr(VI), and the effect of chemical parameters affecting Cr(VI) transport were studied. Good transport features were obtained, demonstrating the suitability of the Raipore R1030 membrane for this application. Thus, an optical sensor for chromium(VI) monitoring in industrial process waters was developed. The sensor is based on the renewable reagent approach and uses the Raipore R1030 membrane as the interface between the sample and the sensor head, which contains 1,5-diphenylcarbazide as spectrophotometric reagent for chromium. Chromium(VI) crosses the membrane and reacts with the reagent inside the sensor head, resulting in changes in the absorption of light. These changes are monitored in situ through a system of optical fibers. The sensor performance was tested by analysing samples from a waste water treatment plant for effluents from electroplating industries.

Abstract
A liquid chromatography-mass spectrometry method is proposed for the determination of seven macrolides authorised in the EU as veterinary drugs for food-producing animals. Sample treatment involves extraction of the analytes with a water-methanol mixture containing metaphosphoric acid and clean-up by SPE with a cation-exchange cartridge. Separation was carried out in an end-capped silica-based C18 column and mobile phases consisting of water/acetonitrile mixtures containing trifluoroacetic acid. A gradient elution, from 28 to 40% acetonitrile was used. Detection was performed by mass spectrometry with electrospray ionisation in the positive mode. Several parameters affecting the mass spectra were studied. The protonated molecular ion was selected for quantitation purposes under selected ion monitoring mode. Detection limits were in the range 1-20 microg l(-1). Recoveries ranged between 56 and 93% with RSD lower than 12%. The method has been successfully applied for multiresidue determination of seven macrolides below the MRLs established by the European Union.

Abstract
Liquid chromatography coupled to electrospray-mass spectrometry (LC-ES-MS) with positive ion detection was evaluated for the determination of tributyltin and triphenyltin in water samples using tripropyltin as internal standard. The separation was performed in the isocratic mode on a silica-based C18 column with a mobile phase containing 0.02% trifluoroacetic acid in acetonitrile-water (50:50, v/v). The optimum LC-ES-MS conditions were established and quantification was performed on the basis of the [M]+ ions. Limits of detection for standard solutions were 100 and 200 pg Sn injected for triphenyltin and tributyltin, respectively, and good reproducibility was observed. Solid-phase extraction was carried out on C18 cartridges to preconcentrate the analytes from natural water samples, with recoveries ranging from 80 to 110%. Limits of detection for SPE-LC-ES-MS were in the range of low ng l(-1), which demonstrates the suitability of the method for environmental samples.
