Suspect and Target Screening of Natural Toxins in the Ter River Catchment Area in NE Spain and Prioritisation by Their Toxicity
toxins Article Suspect and Target Screening of Natural Toxins in the Ter River Catchment Area in NE Spain and Prioritisation by Their Toxicity Massimo Picardo 1 , Oscar Núñez 2,3 and Marinella Farré 1,* 1 Department of Environmental Chemistry, IDAEA-CSIC, 08034 Barcelona, Spain; [email protected] 2 Department of Chemical Engineering and Analytical Chemistry, University of Barcelona, 08034 Barcelona, Spain; [email protected] 3 Serra Húnter Professor, Generalitat de Catalunya, 08034 Barcelona, Spain * Correspondence: [email protected] Received: 5 October 2020; Accepted: 26 November 2020; Published: 28 November 2020 Abstract: This study presents the application of a suspect screening approach to screen a wide range of natural toxins, including mycotoxins, bacterial toxins, and plant toxins, in surface waters. The method is based on a generic solid-phase extraction procedure, using three sorbent phases in two cartridges that are connected in series, hence covering a wide range of polarities, followed by liquid chromatography coupled to high-resolution mass spectrometry. The acquisition was performed in the full-scan and data-dependent modes while working under positive and negative ionisation conditions. This method was applied in order to assess the natural toxins in the Ter River water reservoirs, which are used to produce drinking water for Barcelona city (Spain). The study was carried out during a period of seven months, covering the expected prior, during, and post-peak blooming periods of the natural toxins. Fifty-three (53) compounds were tentatively identified, and nine of these were confirmed and quantified. Phytotoxins were identified as the most frequent group of natural toxins in the water, particularly the alkaloids group. -

Vorsitzende: Univ.‐Prof. Dr. I. Antes Prüfer der Dissertation: 1. Univ.‐Prof. Dr. H.‐W. Mewes 2. Univ.‐Prof. Dr. R. Zimmer (Ludwig‐Maximilians‐Universität München) Die Dissertation wurde am 30. Juli bei der Technischen Universität München eingereicht und durch die Fakultät Wissenschaftszentrum Weihenstephan für Ernährung, Landnutzung und Umwelt am 25. November 2009 angenommen. ACKNOWLEDGEMENTS First and foremost, I would like to express my deep gratitude to my promoter Dr. Volker Stümpflen. Without his continuing, stimulating encouragement and his excellent background in Enterprise technologies still being predominantly used in the IT-industry rather than in academic research, I would not have been able to finish my doctorate in the presented form. Facing the tremendous amount of data that was generated by gathering the positional information of millions of biomedical terms, I was close to cutting the project down to a notably smaller version compared to the text mining system presented in this thesis. Volkers knowledge on database servers and performance tuning significantly contributed to the development of a database schema finally being able to cope with the immense amount of data. I would also like to cordially thank Prof. Dr. Hans-Werner Mewes, head of the Institute for Bioinformatics and Systems Biology (IBIS), for giving me the opportunity to do my doctorate at his institute and for his friendly support and encouragement all along my time at IBIS. -
Properties of Chlorophyllase from Capsicum Annuum L. Fruits

Naturforsch. 56c, 1015-1021 (2001); received June 27/August 6 , 2001 Chlorophyll, Chlorophyllase, Capsicum annuum The in vitro properties of semi-purified chlorophyllase (chlorophyll-chlorophyllido hy drolase, EC 3.1.1.14) from Capsicum annuum fruits have been studied. The enzyme showed an optimum of activity at pH 8.5 and 50 °C. Substrate specificity was studied for chlorophyll (Chi) a, Chi b, pheophytin (Phe) a and Phe b, with K m values of 10.70, 4.04, 2.67 and 6.37 ^im respectively. Substrate inhibition was found for Phe b at concentrations higher than 5 ^m. Chlorophyllase action on Chi a ’ and Chi b' was also studied but no hydrolysis was observed, suggesting that the mechanism of action depends on the configuration at C-132 in the chloro phyll molecule, with the enzyme acting only on compounds with R132 stereochemistry. The effect of various metals (Mg2+, Hg2+, Cu2+, Zn2+, Co , Fe2+ and Fe3+) was also investigated, and a general inhibitory effect was found, this being more marked for Hg2+ and Fe2+. Func tional groups such as -SH and -S-S- seemed to participate in the formation of the enzyme- substrate complex. Chelating ion and the carbonyl group at C3 appeared to be important in substrate recognition by the enzyme. -
Structure of Pigment Metabolic Pathways and Their Contributions to White Tepal Color Formation of Chinese Narcissus Tazetta Var

Received: 7 August 2017; Accepted: 4 September 2017; Published: 8 September 2017 Abstract: Chinese narcissus (Narcissus tazetta var. chinensis) is one of the ten traditional flowers in China and a famous bulb flower in the world flower market. However, only white color tepals are formed in mature flowers of the cultivated varieties, which constrains their applicable occasions. Unfortunately, for lack of genome information of narcissus species, the explanation of tepal color formation of Chinese narcissus is still not clear. Concerning no genome information, the application of transcriptome profile to dissect biological phenomena in plants was reported to be effective. As known, pigments are metabolites of related metabolic pathways, which dominantly decide flower color. In this study, transcriptome profile and pigment metabolite analysis methods were used in the most widely cultivated Chinese narcissus “Jinzhanyintai” to discover the structure of pigment metabolic pathways and their contributions to white tepal color formation during flower development and pigmentation processes. -

The Health Benefits of Grapefruit Furanocoumarins1 Yu Wang and Laura Reuss2
FSHN18-8 The Health Benefits of Grapefruit Furanocoumarins1 Yu Wang and Laura Reuss2 Although not recommended for use with certain medica- tions, grapefruits are known for their numerous health benefits. Both these effects come from, in part, natural chemicals called furanocoumarins. Although these biologically active plant compounds, or phytochemicals, are beneficial to overall health, some compounds have been shown to interact with numerous medications, causing adverse effects known as the “grapefruit juice effect.” Furanocoumarins and flavanones are the major compounds responsible in these drug interactions. Several studies have reported that furanocoumarins present in grapefruit affect absorption of some medications by interfering with a cer- tain liver and intestinal enzyme (Guo et al. 2000). However, numerous studies have shown that compounds in citrus fruits, including furanocoumarins, reduce inflammation and stop cancer cells from multiplying. Furthermore, they Figure 1.
