The goal of this project was to observe certain paths of lipid metabolism in the aorta under the influence of chronic cadmium poisoning. A statistically very significant concentration of cadmium was found in the aortic walls of poisoned rats. However, the concentration of cadmium was not changed in the blood serum, where only a slight tendency towards increase was observed. Among the lipid compounds traced in the blood serum, a considerable increase in triglycerides was observed. The increase in the concentration of total cholesterol in the aortic wall was slight but statistically significant. The concentration of other analyzed lipids--i.e. free fatty acids, triglycerides and phospholipids--did not change. The above observations suggest the hypothesis of the possible development of atherosclerotic changes resulting from chronic cadmium poisoning.

Environmental concerns are rising the need to find cost-effective alternatives to fossil oils. In this sense, short-chain fatty acids (SCFAs) are proposed as carbon source for microbial oils production that can be converted into oleochemicals. This investigation took advantage of the outstanding traits of recombinant Yarrowia lipolytica strains to assess the conversion of SCFAs derived from real digestates into odd-chain fatty acids (OCFA).

Background: Myocardial infarction (MI) remains a leading cause of mortality globally, often resulting in irreversible damage to cardiomyocytes. Ferroptosis, a recently identified form of regulated cell death driven by iron-dependent lipid peroxidation, has emerged as a significant contributor to post-MI cardiac injury. The endoplasmic reticulum (ER) stress response has been implicated in exacerbating ferroptosis.

Today, active packaging has become essential to increase food safety and decrease food spoilage. In this study, the aim was to delay spoilage and increase the shelf life of rainbow fish fillets with a new hybrid nanocomposite active packaging. Packaging was fabricated with Ethylene vinyl acetate and active compounds such as rosemary extract, zinc oxide nanoparticles, and modified iron (Fe-MMT).
