The essential fatty acids react with enzymes to produce a group of compounds known as specialized pro-resolving mediators, or SPMs. Researchers continually discover new members of the four groups of precursors that comprise the SPM family, called lipoxins, resolvins, protectins, and maresins. These stereospecific molecules shut down inflammation and restore the body to homeostasis, a mechanism researchers are targeting for treatment as an alternative to anti-inflammatory pathways.

The Impact

One of the main problems in the departments of anesthesiology and intensive care is the lack of energy in patients. In order to solve it, parenteral nutrition, which contains fat emulsions is prescribed for critical patients. It is known that fat emulsions consist of essential fatty acids which can have both pro-inflammatory (linoleic acid) and anti-inflammatory (linolenic acid) effects. In order to reduce the impact on the immune system, the use of alternative fat emulsions is recommended, as this may provide better clinical results. The first generation of fat emulsions consisted of soybean oil, but it was proven that this oil can increase the risk of purulentseptic complications. Second-generation fat emulsions contain medium-chain triglycerides, the metabolism of which can lead to acidosis, so their use is limited, especially in patients with diabetes. Third-generation fat emulsions contain olive oil, which reduces the risk of thrombosis, is considered immunoneutral and less sensitive to lipid peroxidation. Fourth-generation fat emulsions contain fish oil, which has anti-inflammatory properties and can reduce the duration of patients staying in critical condition. The most promising is the usage of balanced fats, among which there is a 20% SMOFlipid available in Ukraine. For patients who require parenteral nutrition, fat emulsions are an integral part of it, and for critically ill patients fat emulsions containing fish oil are recommended. However, it is recommended to assess baseline triglycerides prior to administration. Thus, lipids provide the delivery of fatty acids that affect important body processes, including metabolism, immune response, blood clotting. Alternative fat emulsions can be a better source of energy, also showing antioxidant effects and less suppression of immune system.

Food is not just a pleasure in life, it is also an important factor for our health. Human nutrition is a mixture of nutrients, which are the only source of energy needed for survival. Energy-poor diet endangers many life functions, and above all the working ability. In the world, the meaning of the diet is very serious, and hence the demands for a –rational, healthy and safe diet are growing. Human nutrition contains saturated and unsaturated fatty acids. Essential fatty acids (EFAs) must be ingested in everyday diet because the body does not produce it. They are very important for human health. They are present in each cell of the human body and are an important factor for the normal growth, development and functioning of cells, muscles, nerves and organs. They are also used in the production of certain hormones - such as prostaglandins, which are crucial for the performance of certain important processes. The deficit from EFAs is due to a number of health problems, including more serious diseases.

Batch Spawning

Fatty acid composition of eggs affects development, growth and ecological performance of fish embryos and larvae, with potential consequences for recruitment success. Essential fatty acids in eggs derive from the maternal diet, and the time between ingestion and deposition in eggs is ecologically important but unknown. We examined the dynamics of diet–egg transfer of arachidonic acid (ARA) in the batch-spawning fish, red drum ( Sciaenops ocellatus ), by measuring ARA concentrations in eggs after a single diet shift and during a period of irregular variations in diet. ARA concentrations in eggs changed within 2–16 days of a diet shift. The rate of change was proportional to the magnitude of the shift, with no evidence of equilibration. These results are not consistent with eggs being assembled entirely from accumulated body stores. The immediate source of ARA in eggs appears to be the recent diet. We propose that batch spawning produces rapid diet–egg transfer of ARA because it removes large amounts of fatty acids from the body and prevents equilibration. The immediacy of the diet–egg connection suggests that spawning migration combined with short-interval batch spawning may have evolved to take advantage of nutrients critical for offspring survival that are available at the spawning site.

Therapy for canine atopic dermatitis can be described as foundation or supplementary. Foundation therapy, which refers to allergen-specific immunotherapy, ciclosporin, glucocorticoids, lokivetmab and oclacitinib, is needed in all but the mildest of cases of canine atopic dermatitis. Supplementary therapies include drugs such as antihistamines, essential fatty acids, topical therapy and other systemic anti-inflammatory drugs. While it is uncommon for any of these supplementary drugs to provide adequate control of many cases of canine atopic dermatitis, they can reduce the frequency of relapse and reduce the amount of foundation therapy that is required when used in combination with them.

Omega-3 fatty acids (Alpha-linolenic acid) and omega-6 fatty acids (Linoleic acid) are a group of essential fatty acids. Essential fatty acids are fatty acids that cannot be synthesized by the body so that must be supplied from the diet. One of the sources of essential fatty acids is derived from fish oil. This study aims to determine the effect of Crude Fish Oil (CFO) in the feed to EPA and DHA content in penaeid shrimp meat. The research method used was a completely randomized design. The treatments used are the varying content of Crude Fish Oil (CFO), which are P0 (0%), P1 (2%), P2 (4%), P3 (6%), and P4 (8%). The results of the study showed significant differences (p <0.05) on the content of EPA and DHA in penaeid shrimp meat. The highest content of EPA and DHA found in P4 treatment (8%) and the lowest at P0 treatment (0%). The use of CFO in penaeid shrimp feed need further study related to the growth of shrimps and prawns reproductive cycle to increase the productivity of penaeid shrimp. CFO on feed should be used at a dose of 6%.

This article is an examination of the Analeptic Applications of Omega-3. The scientific development and subsequent clinical applications of Omega-3 in Healthcare continue to influence researchers all over the globe today. This article examines the research done and published by researchers and scientists. Consideration of current trends and data in scientific queries and demonstrates further aspects of the applications of Omega-3 on various health backgrounds, including. Cardiovascular Health: The study addresses the comparison of Omega-3 and Omega-6 in cardiovascular diseases. Higher intake of dietary Omega-3 helps activation, inhibition, and alteration of metabolic and signaling pathways which is associated with better cardiovascular health, while Omega-6 decreases the risk of coronary heart diseases and cardiovascular disease mortality. Immunology: Omega-3 Polyunsaturated Fatty Acids (PUFAs) have been found to show an anti-inflammatory effect in the body by downregulating the activation of various immune cells. They regulate immunological functions via eicosanoids and resolvins which are anti-inflammatory. External supplementation can reduce chronic and acute inflammation as well as reduce the chances of graft rejection. The regulatory effect is shown by modifying gene expression and/or signal transduction in human cells. They are also involved in altering the membrane composition of Fatty Acids(FA) and as a result, they affect the lipid raft structure and also membrane trafficking. Joint Health: The study shows the effects of omega-3 and other fatty acid consumption in Rheumatoid Arthritis(RA), bone marrow lesions, and knee cartilage lesions. It notes the interrelations between synovitis, plasma levels of Omega-3 and Omega-6 PUFAs in OsteoArthritis (OA) patients along with risk factors for OA, which could help consider liable treatments for improvement of OA. The study highlights the importance of the Omega-6:Omega-3 PUFA ratio and clinical and functional outcome measures which can help us in better understanding the role of PUFAs and possible treatments for people with knee osteoarthritis while showing the effect of Omega-3 fatty acids on muscle health in RA. Skin Disorders: Fish oils rich in PUFAs are reported to improve several inflammatory disorders, including rheumatoid arthritis and psoriasis. They have also been broadly reported as a potential supplement to ameliorate the severity of some skin disorders such as photoaging, skin cancer, allergy, dermatitis, cutaneous wounds, and melanogenesis. The significance of omega-3 in skin structure was proved by describing a syndrome caused by stringent fat reduction in the diet that leads to erythema with scaling, hair loss, itching, and increased water loss.

<p>Lipid and fatty acids are two factors determining reproductive performance of fish and survival rate of hatched larvae. Lipid has important role as energy source and to maintain the stability of membrane permeability.  The requirement of fatty acids differs among fish species.  Freshwater fishes need more n-6 than n-3 fatty acids, or appropriate combination of them.  In several fish species, feeding HUFA increase their fecundity, fertilization rate and eggs quality.  In this study, zebra fish, <em>Danio rerio</em> were fed with diet containing 0% n-3 essential fatty acids and different n-6 level; 0, 1 and 2%.  The result showed that there were no significant differences in gonado somatic index and several reproductive performances observed.  However, 1% of n-6 fatty acids supplementation produced a higher protein and lipid content in the body by 16.85% and 55.10%, respectively.</p> <p>Keywords: fatty acid, n-3, n-6, <em>Danio rerio</em>, reproductive performance</p> <p> </p> <p>ABSTRAK</p> <p>Lemak dan asam lemak merupakan faktor yang sangat mempengaruhi performa reproduksi dan kelangsungan hidup larva yang menetas. Lemak berperan penting sebagai sumber energi dan menjaga kestabilan permeabilitas membran. Kebutuhan asam lemak berbeda untuk setiap jenis ikan.  Ikan air tawar biasanya lebih banyak membutuhkan asam lemak <em>n</em>-6 daripada asam lemak <em>n</em>-3 atau campuran asam lemak <em>n</em>-6 dan <em>n</em>-3. Pada beberapa ikan , pemberian HUFA melalui pakan induk dapat meningkatkan fekunditas, derajat pembuahan dan kualitas telur.  Pada penelitian ini ikan zebra diberi pakan mengandung asam lemak esensial dengan kadar <em>n</em>-3 tetap (0%) dan <em>n</em>-6 berbeda yaitu 0, 1 dan 2%. Hasil penelitian menunjukkan bahwa tidak ada perbedaan nyata terhadap nilai Gonado Somatik Indeks serta beberapa parameter penampilan reproduksi lainnya pada ikan zebra, <em>Danio rerio</em>. Namun kadar asam lemak <em>n</em>-3 sebesar 0% dan <em>n</em>-6 sebesar 1% menghasilkan kadar protein dan kadar lemak tubuh tertinggi yang masing-masing mencapai 16,85% dan 55,10%</p> <p>Kata kunci: asam lemak,  <em>n</em>-3, <em>n</em>-6, <em>Danio rerio</em>, performa reproduksi</p>
