Cholesterol Accumulation Caused Oxidative Stress Associated With Impaired Antioxidant Capability and Mitochondrial Function in the Liver of Nile Tilapia

Aquaculture Nutrition, Volume 2025, Issue 1, 2025.
In mammals, cholesterol accumulation in tissues often results in health damage, such as oxidative stress. In contrast, the adverse effects of cholesterol accumulation on the physiological health of fish remain largely unexplored. The present study investigated the impacts of cholesterol accumulation on oxidative stress and the potential mechanisms ...

Engineering the future of Physalis grisea: A focus on agricultural challenges, model species status, and applied improvements

PLANTS, PEOPLE, PLANET, Volume 6, Issue 6, Page 1249-1260, November 2024.
Groundcherry (Physalis grisea) is a plant species grown for its flavorful fruit. The fruit drops from the plant, hence the common name groundcherry. This makes harvest cumbersome and puts the fruit at risk for carrying soil‐borne pathogens, therefore making them unsellable. Furthermore, insects often damage the plants, reducing yield.

Plant‐based meat analogues marketed in Catalonia: evaluation of the nutritional profile

Food Risk Assess Europe, Volume 2, Issue 3, July 2024.
Abstract In later years, a growing trend is apparent of vegetarian or vegan diets attributable to a number of causes, among of others, consumers’ concern for animal welfare, climate change and, to a lesser degree, for health‐related issues. On a par to this growth, availability of meat analogues in the market has also been on the rise. In this context,
