Luo, Na published the artcileDifferential regulation of intramuscular fat and abdominal fat deposition in chickens, Recommanded Product: Docosahexaenoic Acid, the publication is BMC Genomics (2022), 23(1), 308, database is CAplus and MEDLINE.

Chicken i.m. fat (IMF) content is closely related to meat quality and performance, such as tenderness and flavor. Abdominal fat (AF) in chickens is one of the main waste products at slaughter. Excessive AF reduces feed efficiency and carcass quality. To analyze the differential deposition of IMF and AF in chickens, gene expression profiles in the breast muscle (BM) and AF tissues of 18 animals were analyzed by differential expression anal. and weighted co-expression network anal. The results showed that IMF deposition in BM was associated with pyruvate and citric acid metabolism through GAPDH, LDHA, GPX1, GBE1, and other genes. In contrast, AF deposition was related to acetyl CoA and glycerol metabolism through FABP1, ELOVL6, SCD, ADIPOQ, and other genes. Carbohydrate metabolism plays an essential role in IMF deposition, and fatty acid and glycerol metabolism regulate AF deposition. Conclusion: This study elucidated the mol. mechanism governing IMF and AF deposition through crucial genes and signaling pathways and provided a theor. basis for producing high-quality broilers.

Goswami, Ravi Kumar published the artcileEffect of Lemna minor supplemented diets on growth, digestive physiology and expression of fatty acids biosynthesis genes of Cyprinus carpio, Name: Docosahexaenoic Acid, the publication is Scientific Reports (2022), 12(1), 3711, database is CAplus and MEDLINE.

The potential nutritional value of duckweed Lemna minor (Lemnaceae) was evaluated for common carp Cyprinus carpio fry. Fish were fed diets containing five graded levels of duckweed: 0% (LM0, control), 5% (LM5), 10% (LM10), 15% (LM15) and 20% (LM20). The final weight and specific growth rate were significantly higher in LM15 and LM20 diets fed fish compared to others. Amylase activity was significantly higher in LM0 treatment. Total protease, trypsin and chymotrypsin activities showed linear relationships with the increased level of duckweed in the diet. Protein and essential amino acids contents were significantly higher in carp fed diets LM15 and LM20 compared to others. Lipid content was significantly higher in fish fed duckweed-based diets compared to control. A direct relationship was found between the inclusion level of duckweed in the diet and n-3 long-chain polyunsaturated fatty acid (LC-PUFA) content of carp. Contents of desatd. and elongated products of dietary linolenic acid (18:3n-3) including 20:4n-3, 20:5n-3, 22:5n-3 and 22:6n-3 increased in a graded manner with increasing dietary duckweed. The monounsaturated fatty acids and n-6 PUFA contents reduced significantly in fish fed duckweed. Expression of fads2d6, elovl2, elovl5 and fas were higher in carp fed diets LM10, LM15 and LM20 compared to control fish. The inclusion of L. minor in diet enhanced the nutritional value of carp by increasing protein, lipid, amino acids and n-3 PUFA contents.

Vazquez, Luis published the artcileA new urea adducts method for PUFA concentration using green food grade solvents and avoiding ethyl carbamate formation, SDS of cas: 6217-54-5, the publication is Food Chemistry (2022), 133197, database is CAplus and MEDLINE.

This study aimed to selectively enrich stearidonic acid (SDA) together with ¦Ã-linolenic acid (GLA) in Echium plantagineum oil by urea complexation. The complexation process at room temperature was carried out replacing common organic solvents, such as hexane and ethanol, by alternative compounds, included in Green Solvent and Food Grade categories, adapting this process towards the principles of Green Chem. This substitution was also intended to avoid the generation of the toxic compound Et carbamate. Among all the solvents studied, the mixture propionic acid and ¦Á-pinene provided the best results, leading to a final product comprised of ?99% of PUFA, with ?45% SDA (?14% in the original oil), and without apparition of Et carbamate. The procedure was tested on other raw materials (salmon and microalgae oils). The solvent was efficiently recuperated from the liquid phase (?87% recovery) and reutilized once with almost identical results.

Bhat, Rayees Ahmad published the artcileAnalysis of fatty acids and sex steroid hormones in rainbow trout testes (Oncorhynchus mykiss) during the reproductive process, Computed Properties of 6217-54-5, the publication is Aquaculture Research (2022), 53(12), 4426-4436, database is CAplus.

In the present study, we aimed to examine the cellular structure of the testes, the hormonal changes occurring throughout the reproductive cycle, and the fatty acid composition in rainbow trout. An electron microscopic anal. was conducted to investigate the morphol. and cellular changes during the development of the testes. Germ cells were observed in different stages of differentiation: primary spermatogonia (PSGs), secondary spermatogonia (SSGs), primary spermatocytes (PSCs), secondary spermatocytes (SSCs), spermatids (SPDs) and spermatozoa (SZs). Differentiated spermatozoa were observed within the cysts. Regarding steroid hormones, the maximum level of testosterone was in the mature stage, and the min. level was in the spent stage; for 11-ketotestosterone, the highest level was in the maturing stage and the lowest level was in the spent stage. In terms of the fatty acid composition, the levels of C14, C15, C16, C18, C16:1n7, C18:1n7, C18:1n9, C20:4n6, n-3 PUFAs, n-6 PUFAs, C20:5n-3 (EPA), C22:5n-3 (DPA) and C22:6n3 (DHA) (g^-1 of gonad wet weight) were the lowest during the immature stage and the highest during the mature stage of the testes. The major significance of the study is the sex steroid hormonal profile, the primary regulators of spermatogenesis and the fatty acid composition, which is important for the development of gonads and sperm. These data should contribute to the knowledge regarding the reproductive biol. of male rainbow trout, for which research data remain scarce.

Tagliaferro, Marina published the artcileAssessment of metal exposure (uranium and copper) in fatty acids and carbohydrate profiles of Calamoceras marsupus larvae (Trichoptera) and Alnus glutinosa leaf litter, Category: catalysis-chemistry, the publication is Science of the Total Environment (2022), 155613, database is CAplus and MEDLINE.

Physiol. changes were explored in fatty acids (FA) and carbohydrate (CHO) composition in the shredder Calamoceras marsupus larvae (Trichoptera) and leaf litter (C. marsupus food) exposed to copper and uranium under natural and exptl. conditions. We measured FA and CHO content in leaf litter and larvae specimens from reference and impacted streams, and exposed for 5 wk to four realistic environmental concentrations of copper (35¦Ìg L-1 and 70¦Ìg L-1) and uranium (25¦Ìg L-1 and 50¦Ìg L-1). Regarding FA, (1) leaf litter had a reduced polyunsaturated FA (PUFA) content in metal treatments, s (14 to 33% of total FA), compared to natural conditions (¡Ý39% of total FA). Leaf litter exposed to uranium also differed in saturated FA (SFA) composition, with lower values in natural conditions and higher values under low uranium concentrations (2) C. marsupus had/showed low PUFA content under Cu and U exposure, particularly in high uranium concentrations Detritivores also decreased in PUFA under exposure to both metals, particularly in high uranium concentrations On the other hand, (1) microorganisms of the biofilm colonizing leaf litter differed in CHO composition between natural (impacted and reference) and exptl. conditions, with glucose and galactose being consistently the most abundant sugars, found in different amounts under copper or uranium exposure; (2) CHO of detritivores showed similar high galactose and fucose concentrations in contaminated streams and high copper treatments, whereas low copper treatment showed distinct CHO profiles, with higher mannose, glucose, arabinose, and fucose concentrations Our study provides evidence of metal exposure effects on FA and CHO contents at different trophic levels, which might alter the quality of food flow in trophic webs.

Mikes, Monica published the artcileTranslating PUFA omega 6:3 ratios from wild to captive hibernators (Urocitellus parryii) enhances sex-dependent mass-gain without increasing physiological stress indicators, Name: Docosahexaenoic Acid, the publication is Journal of Comparative Physiology, B: Biochemical, Systems, and Environmental Physiology (2022), 192(3-4), 529-540, database is CAplus and MEDLINE.

Omega 3 polyunsaturated fatty acids (PUFAs) are well-documented for their influence on health and weight loss. Recent studies indicate omega 3 PUFAs may exert a neg. impact on cellular stress and physiol. in some hibernators. We asked if physiol. stress indicators, lipid peroxidation and mass gain in Arctic Ground Squirrels (AGS) were neg. influenced by naturally occurring dietary omega 3 PUFA levels compared to omega 3 PUFA levels found in common laboratory diets. We found plasma fatty acid profiles of free-ranging AGS to be high in omega 3 PUFAs with balanced omega 6:3 ratios, while standard laboratory diets and plasma of captive AGS are high in omega 6 and low in omega 3 PUFAs with higher omega 6:3 ratios. Subsequently, we designed a diet to mimick free-range AGS omega 6:3 ratios in captive AGS. Groups of wild-caught juvenile AGS were either fed: (1) Mazuri Rodent Chow (Standard Rodent chow, 4.95 omega 6:3 ratio), or (2) balanced omega 6:3 chow (Balanced Diet, 1.38 omega 6:3). AGS fed the Balanced Diet had plasma omega 6:3 ratios that mimicked plasma profiles of wild AGS. Balanced Diet increased female body mass before hibernation, but did not influence levels of cortisol in plasma or levels of the lipid peroxidation product 4-HNE in brown adipose tissue. Overall, as the mass gain is critical during pre-hibernation for obligate hibernators, the results show that mimicking a fatty acid profile of wild AGS facilitates sex-dependent mass accumulation without increasing stress indicators.

Habte-Tsion, H.-Michael published the artcileThe effects of fish meal substitution by clam meal on the growth and health of Florida pompano (Trachinotus carolinus), Recommanded Product: Docosahexaenoic Acid, the publication is Scientific Reports (2022), 12(1), 7696, database is CAplus and MEDLINE.

A 12-wk feeding trial was conducted to evaluate the effects of fish meal (FM) substitution by clam meal (CM, at 10%, 20% and 30% of the diet) on the growth, feed utilization, hepatic antioxidant enzymes, plasma parameters, fatty acid and amino acid composition, and gut microbiome of juvenile Florida pompano, Trachinotus carolinus. The results indicated that: (1) juveniles fed 10% and 20% CM had a significantly higher final weight than the group fed the control (0% CM); and the control group also showed significantly lower weight gain, feed intake, protein retention value, whole-body crude protein and total amino acids composition, but higher hepatosomatic index and whole-body crude fat; (2) hepatic peroxide content and superoxide dismutase activity were not significantly affected by the substitution of CM, but it did affect glutathione peroxidase activity, with higher levels found in fish fed 30% CM compared to 0% and 10% CM; (3) plasma total protein, alk. phosphatase, alanine aminotransferase, and IgM showed no significant differences among the treatments; (4) there were no significant differences among treatments in terms of fatty acids composition and microbial diversity. Overall, this study concluded that CM has comparable benefit in the diet of Florida pompano as FM does.

Petit, Angelique published the artcileNutrient sources differ in the fertilised eggs of two divergent broiler lines selected for meat ultimate pH, SDS of cas: 6217-54-5, the publication is Scientific Reports (2022), 12(1), 5533, database is CAplus and MEDLINE.

The pHu+ and pHu- lines, which were selected based on the ultimate pH (pHu) of the breast muscle, represent a unique model to study the genetic and physiol. controls of muscle energy store in relation with meat quality in chicken. Indeed, pHu+ and pHu- chicks show differences in protein and energy metabolism soon after hatching, associated with a different ability to use energy sources in the muscle. The present study aimed to assess the extent to which the nutritional environment of the embryo might contribute to the metabolic differences observed between the two lines at hatching. Just before incubation (E0), the egg yolk of pHu+ exhibited a higher lipid percentage compared to the pHu- line (32.9% vs. 27.7%). Although 1H-NMR spectroscopy showed clear changes in egg yolk composition between E0 and E10, there was no line effect. In contrast, 1H-NMR anal. performed on amniotic fluid at embryonic day 10 (E10) clearly discriminated the two lines. The amniotic fluid of pHu+ was richer in leucine, isoleucine, 2-oxoisocaproate, citrate and glucose, while choline and inosine were more abundant in the pHu- line. Our results highlight quant. and qual. differences in metabolites and nutrients potentially available to developing embryos, which could contribute to metabolic and developmental differences observed after hatching between the pHu+ and pHu- lines.

Xu, Min published the artcileTrophic niche partitioning of five sympatric shark species in the tropical eastern Pacific Ocean revealed by multi-tissue fatty acid analysis, Recommanded Product: Docosahexaenoic Acid, the publication is Environmental Research (2022), 214(Part_1), 113828, database is CAplus and MEDLINE.

Fatty acid (FA) anal. of consumer tissues has recently shown utility in drawing further inferences about trophic niche dynamics of marine predators such as sharks. In this study, we examined liver, plasma, and muscle FAs in five coexisting pelagic sharks (blue (Prionace glauca), silky (Carcharhinus falciformis), bigeye thresher (Alopias superciliosus), pelagic thresher (Alopias pelagicus), and smooth hammerhead (Sphyrna zygaena)) inhabiting the tropical eastern Pacific Ocean. Results showed complex inter- and intra-individual and tissue variation among the five shark species. Based on multivariate anal. of the muscle FAs, P. glauca and C. falciformis have the largest FA niche widths, indicating diverse feeding habits or habitat isolation, whereas A. pelagicus and S. zygaena occupied a narrower niche width, reflecting increased trophic specialization. High percentages of muscle FA niche overlap indicated strong resource competition between S.zygaena and C. falciformis and a degree of dietary isolation by P. glauca. Interpretations of feeding ecol. differed based on the anal. of plasma FAs, which could be attributed to higher dietary FA turnover rates. The liver was deemed unsuitable to examine FA niche metrics based on high and unexplained intra-specific variance in liver FAs as well as the unique lipid metabolism in chondrichthyans. Overall, our multi-tissue approach revealed the magnitude of potential competitive interactions among coexisting tropical shark species. It also expanded our understanding of inter-tissue variability and best practices when using FA anal. to estimate trophic niche metrics of sharks.
