In this study we evaluated the effect of a daily administration of 1 g salmon-oil concentrate containing 0.2 g eicosapentaenoic acid (EPA) on the blood pressure, serum cholesterol, HDL and LDL cholesterol, triglycerides and magnesium of ten patients on chronic haemodialysis. Systolic and diastolic blood pressure values decreased significantly from 156 +/- 27.7/84 +/- 14.3 to 140 +/- 22.8/75.6 +/- 8.21 mmHg. Concordantly, mean arterial pressure (MAP) decreased significantly from 108 to 96 mmHg. Total serum cholesterol decreased significantly by 64%, HDL cholesterol increased by 47% (P less than 0.001). Serum triglyceride values decreased significantly to 48%. There was a distinct decline of magnesium from 1.42 +/- 0.27 to 1.28 +/- 0.13 mg/dl (P less than 0.001). According to these results, the administration of omega-3 fatty acids may be considered as a reasonable approach in the treatment of dyslipoproteinaemia in patients on continuous haemodialysis.

Exaggerated neuronal excitation by glutamate is a well-known cause of excitotoxicity, a key factor in numerous neurodegenerative disorders. This study examined the neurotoxic effect of monosodium glutamate (MSG) in the brain cortex of rats and focused on assessing the potential neuroprotective effects of omega-3 polyunsaturated fatty acids (ω-3 PUFAs). Four groups of adult male rats (n = 10) were assigned as follows; normal control, ω-3 PUFAs (400 mg/kg) alone, MSG (4 mg/g) alone, and MSG plus ω-3 PUFAs (4 mg/g MSG plus 400 mg/kg ω-3 PUFAs).

Meat lipids are determinants of the nutritional, sensory and physiological qualities of meat, encompassing triglycerides, phospholipids, cholesterol and bioactive compounds. These lipids provide essential fatty acids, including omega-3 and omega-6 polyunsaturated fatty acids, critical for metabolic regulation, inflammation control and cognitive health. However, the dual role of meat lipids as essential nutrients and potential contributors to health risks, such as cardiovascular disease and oxidative stress, necessitates a nuanced understanding.

Metabolic syndrome (MS) represents several diseases encompassing a heterogeneous group of biochemical and physiological abnormalities characterized by structural and functional alterations in the myocardium, including the endothelium of the coronary arteries. MS also affects a substantial portion of the global population. Understanding the risk factors, the development and treatment associated with MS are of paramount importance for early identification, treatment and prevention.

Polyunsaturated fatty acids in particular omega-3 fatty acids, such as docosahexaenoic acid (DHA), are essential nutrients and components of the plasma membrane. They are involved in various processes, including synaptic development, functionality, integrity, and plasticity, and are therefore thought to have general neuroprotective properties. Considerable research evidence further supports the beneficial effects of omega-3 fatty acids, specifically on mitochondria, through their antioxidant and anti-apoptotic properties, making them an attractive addition in treatment options for neurodegenerative disorders in which mitochondrial alterations are commonly observed.

Background: COVID-19 is known to cause significant multisystem inflammatory responses, leading to symptoms beyond the acute phase of illness. These "long COVID" symptoms affect quality of life and interfere with daily activities. This pilot study looks at the feasibility, tolerability, and safety of omega-3 (docosahexaenoic acid+eicosapentaenoic acid, EPA) among healthcare workers with long COVID symptoms in New Jersey.
