Rapid liquid chromatographic method for the control of doxycycline and tiamulin residues and their metabolites in vivo assays with pigs: Treatment and depletion

 Journal of Pharmaceutical and Biomedical Analysis, 2020, 190, 113428

DOI:10.1016/j.jpba.2020.113428



Results gained from in vivo metabolism could be more authentic to reflect the biotransformation of drugs than in vitro metabolism. This paper discusses the development and characterization of an analytical method for controlling tiamulin (TIA) and doxycycline (DOX) residues in pig plasma and urine, as well as their in vivo biotransformation during treatment and suppression steps at pig farms. For such a purpose, urine samples were taken daily (24-hr intervals) during treatment and until day 8 after last dose. Plasma samples were collected on the last treatment day and up to days 4 and 7 after the last dose. Only traces of TIA and their metabolites have been still detected 8 days after the last day of therapy, in agreement with the period of suppression of both antibiotics set by the manufacturers in 7 days. It was estimated that TIA and DOX half-lives were of two days and one day, respectively. TIA and DOX metabolites have been identified for the first time in plasma and urine pig samples during treatment and suppression steps.

AA1 & EcoChestnut


EcoChestnut project aims at enhancing the development opportunities and boost the growth potential of European chestnut farmers & chestnut products producers.
 
EcoChestnut main output is an online comprehensive and tailored training on organic chestnuts farming & chestnut products manufacturing. The course focuses also on enhancing the competences on marketing strategy, communication with customers, and diversification of the activities.
 
EcoChestnut project supports farmers and producers in development of their potential for production and promotion of organic chestnuts & chestnut products. EcoChestnut will also provide the vocational trainers with learning methods and material to encourage farmers in their initiative.

Objectives

The EU chestnuts market has been experiencing a strong growth in demand for organic chestnut products for the last 10 years. This demand is unsatisfied in volume, so it has to rely on non-EU imports to be satisfied. The Project aims at enhancing the competitiveness of the EU chestnut farmers and producers.

The main objectives are:
  1. Develop specific knowledge on production and promotion of Organic Chestnuts & Chestnut Products through a tailor made training course for farmers & producers.
  2. Support chestnut farmers & chestnut products producers to enter the market of Organic Chestnuts & Chestnut Products in order to enhance their development opportunities and their growth potential.
  3. Raise awareness in chestnuts & chestnut groves as part of cultural, historical and landscape heritage of the countries that produce them.
  4. Promote sustainable agricultural farming & encourage the application of organic farming among new and existing chestnut farmers and producers.
To answer this needs, EcoChestnut proposes
  1. The EcoChestnut Learning Model
  2. A Training Course on Organic Chestnuts & Chestnut Products
  3. A Manual for Trainers
  4. A Guidebook on Certification of Organic Chestnuts
  5. A Handbook on “Utilize the potential of the chestnut groves”
 
The project is running from November 2019 to April 2022.

Scientific basis for the industrialization of traditionally used plants of the Rosaceae family

Food Chemistry, 2020, 330, 127197

https://doi.org/10.1016/j.foodchem.2020.127197



Plants have been traditionally used for the treatment of different types of illness, due to biomolecules with recognised benefits. Rosaceae family is used in traditional Galician medicine. The following plants Agrimonia eupatoria, Crataegus monogyna, Filipendula ulmaria, Geum urbanum, Potentilla erecta and Rosa canina are usually found in treatments. The aim of this study is to perform an ethnobotanical review about the bioactive compounds of these plants and their different bioactivities, both studied in vitro and in vivo. The nature of the bioactive compounds is varied, highlighting the presence of different phenolic compounds, such as phenolic acids, flavonoids or tannins. Understanding the beneficial effects of the administration of the whole plant or target tissues from A. eupatoria, C. monogyna, F. ulmaria, G. urbanum, P. erecta and R. canina as well as those from their individual compounds could lead to the development of new drugs based on the use of natural ingredients.

The effect of two antifungal commercial formulations on the metabolism of a commercial Saccharomyces cerevisiae strain and their repercussion on fermentation evolution and phenylalanine catabolism

 Food Microbiology, 2020, 92, 103554

DOI: 10.1016/j.fm.2020.103554



The effect of two commercial formulations (incorporating mepanipyrim and tetraconazole as active substances) on the metabolism of Saccharomyces cerevisiae Lalvin T73™, growing on a synthetic grape must, and their influence on the alcoholic fermentation course and the biosynthesis of volatiles derived from phenylalanine catabolism was studied. No relevant effects were observed for mepanipyrim except for glycerol production. On the contrary, in the presence of tetraconazole many genes and some proteins related to cell cycle progression and mitosis were repressed. This fact could explain the lower biomass concentration and the lower sugar consumption registered for tetraconazole at the end of the study. However, the biomass-to-ethanol yield was higher in connection with the overexpression of the ADH1 gene. The presence of tetraconazole residues seems to accelerate the Ehrlich pathway. These results agree with the overexpression of several genes (BAT1, PDC1, PDC5, ADH1, SFA1, ATF2, PFK1, PFK2 and ARO3) and a higher abundance of two proteins (Gap1p and Atf2p) involved in this metabolic pathway.
