Revisados los antecedentes bibliográficos, se manifiesta la importancia de incidir en el estudio de los efectos tóxicos de las floraciones y cultivos de cianobacterias, al igual que de MC puras, en peces debido a que: 1. Viven en el mismo medio en el que
Cylindrospermopsin (CYN) is a cyanobacterial toxin that is gaining importance, owing to its increasing expansion worldwide and the increased frequency of its blooms. CYN mainly targets the liver, but also involves other organs. Various mechanisms have been associated with its toxicity, such as protein synthesis inhibition, oxidative stress,...
The application of stilbenes in the food industry is being considered because of their biological activities. Piceatannol, pterostilbene and ε-viniferin have awakened the industry's interest. However, before they can be commercialized, we must first guarantee their safety for consumers. The present work reviews the toxicological studies...
El níquel (Ni) es un metal tóxico cuyo efecto más prevalente en la población general es la dermatitis alérgica de contacto. Existe la preocupación de que individuos sensibilizados al Ni puedan desarrollar reacciones cutáneas eccematosas tras la exposición dietética, dado que su fuente de exposición principal no ocupacional son los alimentos....
Cylindrospermopsin (CYN) is a cyanotoxin produced by various cyanobacterial species. It is a water soluble zwitterion, stable at extreme temperatures and pH. Despite the main route of exposure to CYN is through drinking water and food, there is a lack of data concerning its intestinal absorption and the mechanisms implicated. The aim of this...
Stilbenes are secondary metabolites of great interest produced by many plant species due to their important bioactive properties. These phytochemicals have become of increasing interest in the wine industry as a natural alternative to sulphur dioxide, which has been associated with human health risks. However, there is still little...
Sulfur dioxide is a controversial preservative used in winemaking. Given its potential toxicity, it is of great interest to find alternatives aimed at replacing or reducing sulfur dioxide. The objective was to assess the antioxidant effects of a grapevine-shoot extract with 99% of stilbenes (ST-99), its major compounds (trans-resveratrol and...
La nanotecnología es una ciencia multidisciplinar que está teniendo un gran auge en la actualidad, ya que proporciona productos (nanopartículas) con nuevas propiedades fisicoquímicas, que son las que hacen que tengan una gran cantidad de aplicaciones. La exposición humana a estas nanopartículas se puede producir principalmente por las vías...
Background Sulforaphane (SFN) is a dietary isothiocyanate, derived from glucoraphanin, present in cruciferous vegetables belonging to the Brassica genus. It is a biologically active phytochemical that acts as a nuclear factor erythroid 2-related factor 2 (Nrf2) inducer. Thus, it has been reported to have multiple protective functions including...
