Possible Fungistatic Implications of Betulin Presence in Betulaceae Plants and their Hymenochaetaceae Parasitic Fungi

2010

Betulin and its derivatives (especially betulinic acid) are known to possess very interesting prospects for their application in medicine, cosmetics and as bioactive agents in pharmaceutical industry. Usually betulin is obtained by extraction from the outer layer of a birch bark. In this work we describe a simple method of betulin isolation from bark of various species of Betulaceae trees and parasitic Hymenochaetaceae fungi associated with these trees. The composition of the extracts was studied by GC-MS, whereas the structures of the isolated compounds were confirmed by FTIR and 1H NMR. Additionally, the significant fungistatic activity of betulin towards some fi lamentous fungi was deter…

Antifungal activity and tautomeric cyclization equilibria of formylphenylboronic acids

2019

2-Formylphenylboronic acid and four isomeric fluoro-2-formylphenylboronic acids have been found active against a series of fungal strains: Aspergillus, Fusarium, Penicillium and Candida. The level of antifungal activity was evaluated by agar diffusion tests as well as the determination of minimum inhibitory concentrations (MICs) by serial dilution method. Among the tested compounds, 4-fluoro-2-formylphenylboronic acid - an analogue of the known antifungal drug Tavaborole (AN2690) - proved to be the most potent antifungal agent. The tautomeric equilibrium leading to the formation of 3-hydroxybenzoxaboroles as well as the position of the fluorine substituent were revealed to play a crucial ro…

The soluble dietary fiber inulin can influence the bioaccessibility of enniatins.

2012

Enniatins (ENs) are bioactive compounds produced by the secondary metabolism of several Fusarium strains and are known to have various biological activities, such as acting as enzyme inhibitors, antifungal antibacterial agents, and immunomodulatory substances. This study investigated the bioaccessibility of the ENs in wheat crispy breads produced with three different inulin concentrations (1, 5 and 10%). The mean bioaccessibility data of the four ENs (A, A(1), B and B(1)) ranged from 68.67% to 84.67 in the experiments carried out without inulin, whereas the data ranged from 51.00 to 74.00% in the experiments carried out with the wheat crispy bread produced with 5 and 10% of the inulin.

Aceites esenciales: productos antimicrobianos y antioxidantes naturales en la industria agroalimentaria

2020

[ES] Los consumidores son conscientes del peligro derivado del uso de antioxidantes y antimicrobianos sintéticos en la industria agroalimentaria, demandando alternativas más seguras y ecológicas. En este estudio, se ha determinado la actividad antioxidante de aceites esenciales comerciales mediante el método DPPH y su efecto antimicrobiano frente a la bacteria Pseudomonas syringae y el hongo fitopatógeno Fusarium oxysporum a través del empleo del método estandarizado de disco. Los aceites esenciales de clavo, ajedrea, canela y orégano, así como carvacrol, mostraron la máxima actividad antioxidante, comparable a antioxidantes establecidos. El aceite esencial de gaulteria fue el más potente i…

Free Action and Interventionist Theory of Causality

2019

Intendo discutere il rapporto tra la teoria interventista della causalità e l’azione libera. Gli approcci interventisti alla causalità definiscono la causazione sulla base dell’“intervento”. Queste teorie possono essere riduttive, se spiegano le cause in base all’intervento umano come libero intervento umano, oppure non-riduttive, se considerano cause e interventi come due concetti inter-definiti, dove gli interventi sono considerati come esplicitamente non umani. Intendo mostrare che il dilemma tra teorie interventista della causalità di tipo riduttivo e non-riduttivo può essere superato in favore degli approcci riduttivi, con riferimento a ciò che la causazione è in senso antropologico e …

mHealth for the Monitoring of Brace Compliance and Wellbeing in Adolescents with Idiopathic Scoliosis: Study Protocol for a Feasibility Study

2021

Escoliosis idiopática del adolescente; Aplicación móvil; Eficacia del tratamiento Escoliosi idiopàtica de l'adolescent; Aplicació mòbil; Eficàcia del tractament Adolescent idiopathic scoliosis; Mobile application; Treatment effectiveness Attempts to optimize monitoring of brace adherence prescribed to adolescents with idiopathic scoliosis (IS) have generally relied on sensors. Sensors, however, are intrusive and do not allow the assessment of psychological and physical consequences of brace use that might underlie poor adherence. Mobile applications have emerged as alternatives to monitor brace compliance. However, the feasibility and utility of these app-based systems to assess key psychol…

Chemical composition and antibacterial effect of Smyrnium olusatrum L. Fruit Essential Oil

2020

The plants of the <em>Apiaceae</em> family are mainly used for food purposes and their multiple therapeutic properties and biological activities. This study aims to determine the chemical composition of Essential Oil (EO) of the fruits of <em>Smyrnium olusatrum</em> L. obtained by hydrodistillation in Clevenger-type apparatus. GC/MS analyzed the EO and the antibacterial activity was evaluated against clinical bacterial strains by two complementary methods (Disc diffusion and micro-atmosphere) and determination of Minimal Inhibitory Concentration (MIC). The results of chemical composition show that the EO is dominated by hydrocarbon monoterpenes (55,95%). The antibact…
