Pikeperch (Sander lucioperca) is a highly profitable com. species whose economic value has greatly increased in the last decade. As in other species, the quality of spermatozoa in this species is a principal feature inherent in fertilization success and efficient natural and artificial reproduction The capacity of fish spermatozoa to be activated and tolerate environmental changes (in osmolality, ion composition, external pH, temperature, etc.) during the motility period contributes to fertilization success. In this study, we investigated the effects of environmental osmolality and ion composition on spermatozoa motility. To determine if the activation mechanism is affected by sperm quality parameters, we measured semen characteristics such as semen volume, spermatozoa concentration, seminal fluid osmolality and ion composition, and spermatozoa lipid composition An addnl. parameter of sperm quality reflecting spermatozoa osmoresistance, the swelling rate, was measured by the nephelometry method. We detected that sperm samples with the highest content of palmitic (C16:0) and palmitoleic (C16:1) acids showed the lowest motility activation under the studied conditions, suggesting that these fatty acids are possible markers for the determination of spermatozoa quality in fish. Our results show that pikeperch spermatozoa can be activated under different osmotic conditions and that cell swelling always accompanies motility. However, spermatozoa sustain their volume under hypotonic conditions when motility is not initiated, suggesting that pikeperch spermatozoa activation is mainly controlled by ion composition rather than the osmolarity of the surrounding medium.

Dvoretsky, Alexander G. published the artcileFatty acids in the circulatory system of an invasive king crab from the Barents Sea, Safety of Docosahexaenoic Acid, the publication is Journal of Food Composition and Analysis (2022), 104528, database is CAplus.

We assayed fatty acids in the cardiac muscle and hemolymph of adult crabs collected in the coastal Barents Sea. Polyunsaturated fatty acids were the major fatty acids (273μg mL^-1 or 42.8% in the hemolymph and 3130μg g^-1 or 59.7% in the cardiac muscle) followed by saturated fatty acids (201μg mL^-1 or 33.9% and 1290μg g^-1 or 24.8%, resp.) and monounsaturated fatty acids (143μg mL^-1 or 23.3% and 815μg g-1 or 15.6%, resp.). The n-3/n-6 ratios in these tissues were 3.4 and 4.3, resp. Fatty acid profiles were similar in females and males, in crabs with different shell conditions and in different-sized crabs. The crabs captured on soft bottoms contained significantly higher concentrations of fatty acids in their hemolymph than the crabs from hard bottoms probably owing to differences in their diets. In general, fatty acid levels in the cardiac muscle were 1.5-3 times higher than in the leg muscle reflecting higher functional load of the heart compared to walking legs. We suggest that both byproducts that now are discarded during red king crab processing could be considered addnl. sources for extracting valuable n-3 fatty acids.

Aboal, M. published the artcilePhotoautotrophs and macroinvertebrate trophic relations in calcareous semiarid streams: The role of Cyanobacteria, Computed Properties of 6217-54-5, the publication is Science of the Total Environment (2022), 838(Part_3), 156206, database is CAplus and MEDLINE.

Photoautotrophs and macroinvertebrate trophic relations in Mediterranean streams, especially from semiarid areas, are still poorly known, as is the role of Cyanobacteria, which is the most frequently dominant photoautotroph. To investigate the role of Cyanobacteria as a food resource in these systems, the fatty acid composition of primary and secondary producers was investigated in two streams on a semiarid climatic gradient between 200 and 500 mm of rainfall in SE Spain. Fatty acid composition of photoautotrophs and macroinvertebrates differed among streams in summer and among seasons in each stream. Fatty acid fingerprints show that macroinvertebrates usually fed on the dominant photoautotroph assemblage and that Cyanobacteria represent the main food for all the feeding groups in the Alharabe stream in winter although filamentous green algae were preferred in summer. Only scrapers consuming Chlorophyta displayed a selective feeding behavior. The results show the importance of cyanobacteria as food for all collected macroinvertebrates in winter in some semiarid streams and confirm that fatty acids can be used as temporal and spatial markers in fluvial systems.

Maldonado-Pereira, Lisaura published the artcileEvaluation of the nutritional quality of ultra-processed foods (ready to eat + fast food): Fatty acids, sugar, and sodium, Application of Docosahexaenoic Acid, the publication is Journal of Food Science (2022), 87(8), 3659-3676, database is CAplus and MEDLINE.

The average American consumes more than 50% of their total dietary energy from ultra-processed foods (UPFs). From a nutritional standpoint, as UPFs intake increases, fiber, vitamin, and mineral intake decrease. High consumption of UPFs, mainly from fast foods (FF) and ready-to-eat (RTE) food items, emerges as a critical public health concern linking nutritional quality and food safety. In the present work, a systematic database of the fatty acid composition of the most consumed UPFs in the Midwest is reported. Saturated and monounsaturated fatty acids were predominant in RTE (42.5%) and FF (43.2%), resp. In addition, the fatty acid profile in UPFs is reported according to six food categories: meat and poultry, eggs and derivatives, dairy products, seafood, baby foods, and others. Meat and poultry, and dairy products were the dominant food categories among UPFs. Meanwhile, polyunsaturated fatty acids were abundant in the eggs and seafood groups UPFs (61.8% and 46.4%, resp.) regardless of the food group. Furthermore, no significant differences were found in sugar content in UPFs. Caloric content was pos. correlated with sodium (ρ = 0.748) and price (ρ = 0.534). The significance of this study relies on providing new quant. data on the fat, sodium, and sugar contents of the most consumed UPFs in the Midwestern area of the United States. This information suggests paying more attention to these nutritional attributes, aiming to reduce their incorporation in UPF preparations Addnl., more quant. data are needed regarding other nutritional parameters such as protein and lipid degradation in UPFs.

Lo, Enlin published the artcilePhysiological insights into enhanced lipid accumulation and temperature tolerance by Tetraselmis suecica ultraviolet mutants, Name: Docosahexaenoic Acid, the publication is Science of the Total Environment (2022), 156361, database is CAplus and MEDLINE.

High outdoor temperatures significantly inhibit the growth and lipid production of the industrially promising marine microalga Tetraselmis suecica, which is viewed as a potential feedstock for high-value bioproducts and biofuels. To overcome this limitation, T. suecica was subjected to UV irradiation to generate mutants capable of being productive at higher temperatures The top two high-lipid mutants UV-25 and UV-31 isolated at 25°C and 31°C, resp., were compared to the wild type (WT) to delineate physiol. alterations and shed light on the mutants increased biomass and lipid productivity. At 25°C, UV-25 and UV-31 exhibited lipid productivity of 36.12 and 31.33 mg/L day, which were 1.4- and 1.2-fold higher than WT, resp. This increase in lipid biosynthesis correlated well with increased carotenoid content in UV-25 (2.2-fold) and UV-31 (3.6-fold), indicating an improved capacity to quench reactive oxygen species. At 31°C, the growth and lipid accumulation of UV-31 remained high, signifying adaptation to higher temperatures This is attributed to a well-coordinated modulation of the mutant’s cellular metabolism through an increase in galactose and phosphatidylglycerol levels, as well as in protein, all of which contributed to its performance at elevated temperatures The study successfully established a UV mutagenesis strategy for producing superior- performing microalgae strains with industrially desired traits, paving the way for future outdoor cultivation deployment.

Quispe, Renato published the artcileControversies in the Use of Omega-3 Fatty Acids to Prevent Atherosclerosis, Related Products of catalysis-chemistry, the publication is Current Atherosclerosis Reports (2022), 24(7), 571-581, database is CAplus and MEDLINE.

A review. Abstract: Purpose of Review: We discuss current controversies in the clin. use of omega-3 fatty acids (FA), primarily eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), and examine discrepancies between recent trials. Furthermore, we discuss potential side effects reported in these studies and the role of mixed omega-3 FA dietary supplements and concerns about their use. Recent Findings: REDUCE-IT showed that addition of icosapent Et, a highly purified form of EPA, can reduce risk of cardiovascular events among statin-treated individuals with high triglycerides. Addnl. supportive evidence for EPA has come from other trials and meta-analyses of omega-3 FA therapy. In contrast, trials of mixed EPA/DHA products have consistently failed to improve cardiovascular outcomes. Discrepancies in results reported in RCTs could be explained by differences in omega-3 FA products, dosing, study populations, and study designs including the placebo control formulation. Evidence obtained from highly purified forms should not be extrapolated to other mixed formulations, including “over-the-counter” omega-3 supplements. Summary: Targeting TG-rich lipoproteins represents a new frontier for mitigating ASCVD risk. Clin. and basic research evidence suggests that the use of omega-3 FA, specifically EPA, appears to slow atherosclerosis by reducing triglyceride-rich lipoproteins and/or inflammation, therefore addressing residual risk of clin. ASCVD.

Adeyemi, Kazeem D. published the artcileGrowth Performance, Carcass Traits, Muscle Fatty Acids, Intramuscular Fat, Cholesterol, and Antioxidant Status in Rabbits Supplemented with Kigelia pinnata Leaf Meal, Quality Control of 6217-54-5, the publication is European Journal of Lipid Science and Technology (2022), 124(8), 2200014, database is CAplus.

The effects of dietary Kigelia pinnata leaf (KPL) on growth, carcass, muscle fatty acids, antioxidant status, cholesterol, physicochem. properties, and sensory profile of Longissimus thoracis et lumburum (LTL) muscle in rabbits are investigated. Seventy-two, 32 d old male New Zealand rabbits (684 ± 18 g) are randomly assigned to diets containing either no KPL (KPL-0), 5% KPL (KPL-5) or 10% KPL (KPL-10) for eight weeks, and euthanized, and the LTL is refrigerated for 6 days. Dietary KPL does not influence growth performance and carcass cuts in rabbits. Abdominal fat is lower in KPL- rabbits than in the KPL-0 rabbits. Supplemented LTL has lower i.m. fat and cholesterol, and higher crude protein, polyphenol content, glutathione reductase, and catalase compared with the control LTL. Concentration of C18:3n-3, C22:6n-3, and C20:5n-3 is higher in supplemented LTL than the control LTL. Supplemented meat has lower cook loss than the KPL-0 meat at 24 h postmortem. The KPL-10 meat has higher redness and lower malondialdehyde content than other meats on d 6 postmortem. Juiciness and overall acceptance of the supplemented meat are higher than that of the KPL-0 meat. Supplementation with KPL-10 enhances muscle n-3 fatty acids, sensorial quality, and oxidative stability of rabbit meat. Rabbit meat is replete in n-6 polyunsaturated fatty acid (PUFA) but low in n-3 PUFA, which heightens its n-6/n-3 ratio. Higher n-6/n-3 PUFA intake can pose serious health risks to consumers. This suggests a need to ameliorate the n-3 PUFA of rabbit meat. Dietary KPL causes ‘147-184% increase in n-3 PUFA and a 66-77% decrease in n-6/n-3 ratio in rabbit meat. Moreover, KPL improves sensorial quality and oxidative stability and lowers i.m. fat and cholesterol content of rabbit meat. These results support the delivery of a healthier rabbit meat that responds to consumer demands. This study explicates the potential of KPL in ameliorating the nutritional value and sensory quality of rabbit meat.

Reis, Mariza G. published the artcileComparative evaluation of miniaturized and conventional NIR spectrophotometer for estimation of fatty acids in cheeses, Formula: C22H32O2, the publication is Spectrochimica Acta, Part A: Molecular and Biomolecular Spectroscopy (2022), 121433, database is CAplus and MEDLINE.

The miniaturization of near-IR spectrometers has been growing rapidly. Several designs are now available, but there is a lack of understanding of how spectral data from these designs are affected by complex matrixes and what are the limitations when compared to established systems. This study compares a popular miniaturized NIR device based on Hadamard-transform spectrometer (named miniaturized NIR) with a system based on dispersive spectrometer (named handheld-NIR) to assess:. (1) Their predictive performance;. (2) The effect of a complex matrix on the performance, and. (3) Ability to discriminate multiples compounds in that matrix. The devices were challenged with a wide range of cheese types (n = 36) from different species (cow, goat, ewe and buffalo), brands (n = 30), countries of origin (n = 9) and with a broad range of cheese matrixes (soft, fresh, semi-hard, hard and aged) to predict fat composition Spectra were collected non-invasively with no sample preparation Three wavelength ranges from handheld NIR were compared to miniaturized NIR based on two modeling approaches were used: a linear (Partial Least Square – PLS) and a non-linear (Support Vector Machine – SVM). The important wavelengths for each model were identified and used to assess the ability of the spectral data to differentiate among fatty acids. The highest prediction performance was observed for saturated fatty acids (C4.0, C14.0, C15.0 C16.0, total SCF and total SFA) with the RPD_EXT-VAL for the external validation dataset presenting values higher than 3 and the coefficient of determination for the external validation dataset (R²_EXT-VAL) higher than 0.89, mostly for SVM models. The sum of fatty acids also shows good prediction performance with RPD_EXT-VAL higher than 3 and R²_EXT-VAL higher than 0.89. Models with RPD_EXT-VAL between 2 and 3 includes: C6.0; C17.0; C18.0; C10.1; C16.1; C17.1; iso.C15.0; iso. C.16; iso.C17; C18.1.c11; C18.1.c9; anteiso C17; total MUFA; and total BCFA. The cheese matrix affected the linearity between spectral data and fatty acids concentration requiring a more complex model (SVM), but this effect was not enhanced by the instrument type. It was shown that the spectral information allows discrimination among fatty acids and this ability was not affected by the type of instrument. These findings demonstrated that the miniaturized NIR can be directly applied to a cheese matrix to monitor fatty acid composition with results equivalent to an optical-based design.

Martinot, Pauline published the artcileLC-PUFA enrichment in infant formula and neurodevelopment up to age 3.5 years in the French nationwide ELFE birth cohort, Category: catalysis-chemistry, the publication is European Journal of Nutrition (2022), 61(6), 2979-2991, database is CAplus and MEDLINE.

For decades, consistent associations between breastfeeding and children′s neurodevelopment have been attributed to breastmilk content in long-chain polyunsaturated fatty acids (LC-PUFAs). However, the beneficial effect of LC-PUFA enrichment of infant formula on neurodevelopment remains controversial. This study examined the association of LC-PUFA enrichment of infant formulas with neurodevelopment up to age 3.5 years. Analyses were based on 9372 children from the French nationwide ELFE birth cohort. Monthly from 2 to 10 mo, parents declared their infant′s feeding mode, including breastfeeding and the name of the infant formula, which allowed for identifying formulas enriched in arachidonic (ARA), eicosapentaenoic (EPA) and/or docosahexaenoic (DHA) acids. Neurodevelopment was assessed at age 1 and 3.5 years with the Child Development Inventory (CDI-1 and CDI-3.5); at 2 years with the MacArthur-Bates Communicative Development Inventories (MB-2); and at 3.5 years with the Picture Similarities subtest of the British Ability Scale (BAS-3.5). Associations were assessed by linear regression adjusted for any breastfeeding duration and main confounding factors, including socioeconomic characteristics. One-third of formula-fed infants consumed LC-PUFA-enriched formulas. Most of these formulas were enriched in both DHA and ARA, and about 10% of infants consumed formula further enriched in EPA. LC-PUFA enrichment of infant formula was not associated with neurodevelopmental scores at age 1 (CDI-1, – 0.16 [- 0.39, 0.07]), age 2 (MB-2, 0.78 [- 0.33, 1.89]), or age 3.5 (CDI-3.5, – 0.05 [- 0.27, 0.17]; BAS-3.5, – 0.93 [- 2.85, 0.98]). In the ELFE study, LC-PUFA enrichment of infant formula was not associated with neurodevelopmental scores up to 3.5 years.
