LC-MS/MS characterisation and determination of dansyl chloride derivatised glyphosate, aminomethylphosphonic acid (AMPA), and glufosinate in foods of…

2021

Abstract Glyphosate and other polar and acidic pesticides have been particularly studied due to the concerns over widespread and intensive use. The chemical properties of these compounds necessitate use of customised methods, such as derivatisation or ion exchange chromatography. These approaches present a compatibility problem with ESI-MS due to presence of salts and non-volatile compounds. For that reason, a simple procedure has been developed for the extraction, pre-column derivatisation with dansyl chloride (5-(dimethylamino)naphthalene-1-sulfonyl chloride), and mass spectrometric detection of glyphosate, AMPA, and glufosinate after the separation on a C18 stationary phase. The dansyl d…

Molecular and morphological identification of larval opecoelids (Digenea: Opecoelidae) parasitising prosobranch snails in a Western Mediterranean lag…

2012

In a study of the digeneans parasitising molluscs in the Els Alfacs lagoon (Ebro Delta, Western Mediterranean) we found heavy infections with sporocysts emitting two types of cotylocercous cercariae in the prosobranch trochid gastropod Gibbula adansonii and with metacercariae in the prosobranch nassariid gastropod Cyclope neritea. A comparative analysis using ITS ribosomal DNA sequences from these larval stages and published sequences of 17 larval and adult opecoelid stages allowed us to elucidate the life-cycle of Macvicaria obovata and to confirm the identification of Cainocreadium labracis based on cercarial morphology. We provide molecular evidence for the identification and the first d…

Anthropometric and pharmacotherapeutic variables on acute emesis induced by cisplatin-containing chemotherapy.

2000

OBJECTIVE: To characterize the effects of anthropometric and pharmacotherapeutic variables on acute emesis induced by cisplatin-containing regimens with dosages ·50 mg·m−2. METHODS: A prospective, cross-sectional, noncontrolled study was performed to analyze acute vomiting during the first 24 hours in patients treated in a Spanish hospital. The patients received an intravenous combination of drugs (2 doses of metoclopramide 3 mg/kg, dexamethasone 20 mg) as first-choice antiemetic therapy. Intravenous ondansetron 8 mg and dexamethasone 20 mg served as an alternative regimen in patients <30 years old with a history of extrapyramidal manifestations or emesis in previous cycles. Therapeutic …

Mobilisation of plasmid-mediated blaVEB-1 gene cassette into distinct genomic islands of Proteus mirabilis after ceftazidime exposure

2021

ABSTRACT Objectives We sought to integrate a VEB-1-encoding gene cassette into the integron of the MDR region of genomic islands (GIs) harboured by Proteus mirabilis strains after antibiotic exposure. Methods An IncP1 plasmid from Achromobacter xylosoxidans carrying the cassette array dfrA14–blaVEB-1–aadB was introduced by conjugation into five strains of P. mirabilis: PmBRI, PmABB, PmSCO and Pm2CHAMA harbouring Salmonella GI 1 and PmESC harbouring Proteus GI 1. Circular intermediates of the cassettes were amplified by PCR. blaVEB-harbouring P. mirabilis were exposed to increasing concentrations of ceftazidime each day. Presence of blaVEB-1 in the GI was assessed by PCR. The complete MDR re…

Identification of microplastics using 4‐dimethylamino‐4′‐nitrostilbene solvatochromic fluorescence

2021

In this work, we introduce the use of 4-dimethylamino-4'-nitrostilbene (DANS) fluorescent dye for applications in the detection and analysis of microplastics, an impendent source of pollution made of synthetic organic polymers with a size varying from less than 5 mm to nanometer scale. The use of this dye revealed itself as a versatile, fast and sensitive tool for readily discriminate microplastics in water environment. The experimental evidences herein presented demonstrate that DANS efficiently absorbs into a variety of polymers constituting microplastics, and its solvatochromic properties lead to a positive shift of the fluorescence emission spectrum according to the polarity of the poly…

Biowaiver Monograph for Immediate-Release Solid Oral Dosage Forms: Ondansetron.

2019

Literature data pertaining to the physicochemical, pharmaceutical, and pharmacokinetic properties of ondansetron hydrochloride dihydrate are reviewed to arrive at a decision on whether a marketing authorization of an immediate release (IR) solid oral dosage form can be approved based on a Biopharmaceutics Classification System (BCS)-based biowaiver. Ondansetron, a 5HT3 receptor antagonist, is used at doses ranging from 4 mg to 24 mg in the management of nausea and vomiting associated with chemotherapy, radiotherapy, and postoperative treatment. It is a weak base and thus exhibits pH-dependent solubility. However, it is able to meet the criteria of "high solubility" as well as "high permeabi…
