Exploring the therapeutic potential of acorn extract in papillomavirus-induced lesions.

Background And Aim: Papillomaviruses (PVs) infections have been documented in numerous animal species across different regions worldwide. They often exert significant impacts on animal health and livestock production. Scientists have studied natural products for over half a century due to their diverse chemical composition, acknowledging their value in fighting cancer.

Behavioral, metabolic, and biochemical alterations caused by an acute stress event in a zebrafish larvae model.

Animal welfare is a growing concern in aquaculture practices. Stress induced by handling or transportation can lead to negative impacts on the sector. Zebrafish has raised as an important aquaculture model, but still with few focus on its stress response in early life stages.

Early developmental effects of propofol exposure in different stages of zebrafish embryos.

The mechanism of action of propofol, a common intravenous anaesthetic, in early life stages is not well understood with contradictory studies showing neurotoxic and neurogenic effects in the developing brain. Zebrafish early life stages have been established as an alternative model for animal experimentation with propofol toxicological effects reported following chronic exposure. Yet, the acute exposure to other anaesthetics has been shown to induce early life stage-dependent toxicological outcomes.

Effects of atrazine, diuron and glyphosate mixtures on zebrafish embryos: acute toxicity and oxidative stress responses.

Synthetic pesticides are known for their toxic effects on non-target aquatic organisms. However, little is known about their effects when present in mixtures, which are closer to realistic exposure scenarios. Therefore, this study evaluates the toxicity of pesticides such as diuron, atrazine and glyphosate, individually and in combination, in zebrafish embryos, investigating their mechanisms of oxidative stress.

Development of antioxidant films based on anthocyanin microcapsules extracted from purple corn cob and incorporated into a chitosan matrix.

Biodegradable food packaging films were prepared from chitosan incorporated with microencapsulated anthocyanins powder (MAP) that was extracted from purple corn cob using the casting method. Anthocyanins extracts were microencapsulated with maltodextrin, gum arabic, and soy protein using a spray-drying method. The film based on chitosan and MAP (CHt@MAP) was prepared through citric acid cross-linking and plasticization with glycerol.
