Purpose: To examine the effects of the oil mixes (ω-9, ω-6 and ω-3) in rats subjected to thermal burn. It was also aimed to assess whether the sources of ω3 would interfere with the effect of such mixes on the thermal injury.
Methods: Thirty-six rats distributed into five groups: burned + water, burned + isolipid mix, burned + oil mix 1 (ALA), burned + oil mix 2 (ALA + EPA + DHA of fish) and burned + oil mix 3 (ALA + DHA from seaweed). The thermal injury was involving total thickness of skin. After the burns animals received the oil mixes for seven days. The lesions were evaluated by immunohistochemistry.
Results: Animals receiving mix 3 showed a smaller extension of the thermal injury as compared to those that were supplemented with other oils mixes. Expression of Ki-67 in the receiving Mix 3 increased as compared to all the other groups. Animals supplemented with mix 3 were able to inhibit NF-κB in injured tissue.
Conclusion: Rats received oil mix in which the source of ω3 (ALA+DHA of seaweed) showed inhibition of NF-κB, increase in cell proliferation, and reduction the extension of thermal lesion.

Hydrogen (H) offers a less carbon-intensive energy production method than natural gas. The potential of utilizing hydrogen at a large scale within the future energy mix to fuel the world opens the door to investigating hydrogen production from heavy and extra-heavy oil reservoirs. Various reaction mechanisms are involved in the in situ combustion gasification of heavy oil to produce sustainable and low carbon intensive hydrogen.

Hermetia illucens larvae oil (HIO) is a promising new ingredient that can potentially be an alternative lipid source in aquafeeds. To assess its viability in gilthead seabream juvenile diets, a 10-week feeding trial was performed, and the effects on antioxidant, immune, and inflammatory responses were evaluated. Four diets were formulated to include HIO at increasing levels: 0, 4, 7.

Background: The best space maintainer in both primary and mixed dentition is the primary tooth itself. This is not only because of the clinical crown but also due to the presence of the roots and periodontium that guide the eruption of the permanent tooth. Although over the years many materials have been tried for obturation of pulpectomized primary teeth, no material has been found to fulfill all requirements.

The aim of this study was to determine the effect of milk thistle (Silybum marianum L., SM) oil supplementation on proinflammatory cytokines, acute phase proteins, rumen metagenomic profile, rumen fluid variables and performance during the milk feeding period of Holstein calves. In the present study, 24 calves that consumed quality and sufficient amount of colostrum (≥50 mg/ml IgG) after birth were divided into three groups, with 8 animals in each group (4 males + 4 females).

The Athabasca oil sands region of Alberta, Canada contains one of the world's largest unconventional petroleum deposits. There is concern about residual contaminants where tailings are integrated during reclamation and the related adverse effects this may have. Some of the primary toxic organic contaminants in oilsands tailings are naphthenic acid fraction compounds (NAFCs).
