The effects of steaming, grilling, and frying in corn and sunflower oils, respectively, on the fatty acid compositions of farmed and wild sea bream were evaluated. The lipid content increased with frying in both oil types. The maximum moisture value was found in steamed fish (P<0.05). Fried sea bream in corn and sunflower oils contained a lower content of n-3 polyunsaturated fatty acids (P<0.05) (3.87 and 5.32% of total fatty acids (TFA) in farmed fish and 2.96 and 2.14% TFA in wild fish). The n-3/n-6 ratio decreased significantly after cooking, particularly after frying in corn and sunflower oils, respectively: from 2.51 to 0.08 and 0.12 in farmed fish and from 0.94 to 0.06 and 0.04 in wild fish. The trans fatty acid levels remain stable after steaming and grilling, but they were significantly affected by frying. Our results reveal that the cooking process has considerable effect on the fatty acid compositions of farmed and wild sea bream.

This study was designed to evaluate the effect of substituting alfalfa hay with graded levels panicum maximum without or with graded levels of spirulina supplementation on rumen fermentation and nutrient degradability. The evaluation was achieved through an in vitro study, rumen fluid was obtained from adult sheep aged 2 years (fed clover hay), immediately after slaughter. Experimental diets were formulated as isonitrogenous and isocaloric and contained 40% forage.

Hepatocellular carcinoma (HCC) is a predominant cause of cancer-related mortality globally, noted for its propensity towards late-stage diagnosis and scarcity of effective treatment modalities. The process of metabolic reprogramming, with a specific emphasis on lipid metabolism, is instrumental in the progression of HCC. Nevertheless, the precise mechanisms through which lipid metabolism impacts HCC and its viability as a therapeutic target have yet to be fully elucidated.

Phosphatidylcholine is a ubiquitous phospholipid. It contains a phosphocholine (PC) headgroup and polyunsaturated fatty acids that, when oxidized, form reactive oxidized phospholipids (PC-OxPLs). PC-OxPLs are pathogenic in multiple diseases and neutralized by anti-PC IgM antibodies.

Challenges in drug development for rare diseases such as pulmonary arterial hypertension can be addressed through the use of mathematical modeling. In this study, a quantitative systems pharmacology model of pulmonary arterial hypertension pathophysiology and pharmacology was used to predict changes in pulmonary vascular resistance and six-minute walk distance in the context of oral treprostinil clinical studies. We generated a virtual population that spanned the range of clinical observations and then calibrated virtual patient-specific weights to match clinical trials.
