This work aimed to conduct a comparative analysis that helps to identify the effect of the developed technology on the chemical composition of drinking yogurts made from Australian and Kazakhstani dromedary camel milk. Camel milk taken from Kazakhstan and Australia has been processed into drinking yogurt and its amino, fatty acid, vitamin, and mineral content was assayed. These identifications enabled us to compare how our developed technology is suitable for both milk types. The results of determination can be interpreted as follows. The essential and non-essential amino acid content in Kazakhstani yogurt was significantly higher compared to Australian yogurt. Aspartic and Glutamic acids were not identified in Kazakhstani yogurt. As a counterpart, Lysine and Histidine were not found in Australian yogurt. The fatty acid results demonstrated that Linoleic acid in Kazakhstani yogurt was significantly higher than in Australian yogurt, and there was more Linolenic acid in Australian yogurt than in Kazakhstani yogurt. The atherogenicity index for Kazakhstani yogurt was at a low level (0.045 %) compared to Australian yogurt (1.90 %). The ratios of omega 6 and omega 3 in Kazakhstani yogurt were 16 % greater than in Australian yogurt. Thiamine level in Kazakhstani yogurt was lower compared to Australian by up to 57 %. However, Riboflavin results in both samples were identical. The Calcium, Potassium, Sodium, and Phosphorus contents in Australian yogurt are defined as 5, 34, 34, and 30 % respectively compared to Kazakhstani yogurt. Nevertheless, Magnesium (47 %) and Iron (60 %) levels were lower in Australian yogurt than in Kazakhstani yogurt. These study results could be useful as preliminary work for scientists and producers of gerodiet products, who intend to work with camel milk as a geroprotector

Objective: Although studies suggest that erythrocyte concentrations of omega-3 and omega-6 fatty acids are lower in individuals with schizophrenia, evidence of beneficial effects of omega-3 fatty acid supplementation is limited. This study therefore aimed to determine whether omega-3 and omega-6 fatty acid levels are causally related to schizophrenia. Methods: Causality was evaluated using the inverse variance weighted (IVW) 2-sample Mendelian randomization (MR) method using fatty acid levels and schizophrenia genome-wide association study results. Weighted median, weighted mode, and MR Egger regression methods were used as sensitivity analyses. To address the mechanism, analyses were performed using instruments within the FADS and ELOVL2 genes. Multivariable MR (MVMR) was used to estimate direct effects of omega-3 fatty acids on schizophrenia, independent of omega-6 fatty acids, lipoproteins and triglycerides. Results: MR analyses indicated that long-chain omega-3 and omega-6 fatty acid levels were associated with lower risk of schizophrenia (docosahexaenoic acid [DHA] ORIVW: 0.83, 95% CI: 0.75-0.92). In contrast, short-chain fatty acids were associated with an increased risk of schizophrenia (alpha-linolenic acid ORIVW: 1.07, 95% CI: 0.98-1.18). Causal effects were consistent across sensitivity and FADS single-SNP analyses. MVMR indicated that the protective effect of DHA on schizophrenia persisted after conditioning on other lipids (ORIVW: 0.84, 95% CI: 0.71-1.01). Conclusions: Results are consistent with protective effects of long-chain omega-3 and omega-6 fatty acids on schizophrenia suggesting that people with schizophrenia may have difficulty converting short-chain to long-chain PUFAs. Long-chain PUFA supplementation or diet enrichment, particularly in higher risk individuals, might help prevent onset of disorder.

Chemical composition and fatty acid profile of fillets from farmed and wild common carp were assessed in the course of four seasons. Ten wild and ten0 farmed fish were collected in the middle month of each season (except summer due to unavailability of wild fish) during the year. Lipid and protein contents of the samples decreased from summer to spring (protein: 17.6 ± 0.3–15.9 ± 1.6; 18.2 ± 0.1–17.9 ± 1.4%, in the farmed and wild carp samples, lipid (5.1 ± 0.2–1.5 ± 0.5; 3.8 ± 0.6–2.8 ± 0.9%, respectively; P > 0.05), moisture content of both samples increased in this period (76.7 ± 1.4–81.4 ± 0.4, 75.5 ± 0.6–78.5 ± 0.2 in the farmed and wild carp, respectively). Protein content of wild carp fillet was higher (17.7 ± 0.8% protein vs. and 16.2 ± 1.2%) and moisture content was lower than those of the farmed counterparts (77.65 ± 0.6 vs. and 79.3 ± 0.1, P < 0.05). In all seasons, MUFA were higher than SFA and also the PUFA. In the wild carp fillet, PUFA was higher than SFA in winter and spring but in the farmed carp it was higher in all seasons except the spring. Palmitic, oleic, and DHA were the major SFA, MUFA, and PUFA in the wild carp fillet, respectively. In the farmed carp fillet, the major SFA and MUFA were similar to those in the wild one but linoleic acid was the major PUFA in all seasons. ω-3/ω-6 PUFA ratios in the wild carp fillet were higher than in the farmed counterparts.

AbstractLong-Chain Polyunsaturated Fatty Acid (LCPUFA) is essential throughout pregnancy, since deficiency of LPUFA may linked to obstetrical complications. This study aimed to investigate LCPUFA status in severe preeclampsia and preterm birth. A cross sectional study was conducted in 104 pregnant women, which divided into normal pregnancy, severe preeclampsia and preterm birth groups. Serum percentage and concentration of total LCPUFA, omega-3, alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), omega-6, linoleic acid (LA), and arachidonic acid (AA) were measured using gas chromatography/mass spectrometry. Receiver operating characteristic (ROC), bivariate and multivariate analysis were performed. Severe preeclampsia showed the highest concentration of total PUFA and the lowest DHA percentage, with significantly higher Omega-6/Omega-3 ratio (p = 0.004) and lower omega-3 index (p < 0.002) compared to control. Preterm birth showed the least omega-3 concentrations, with significantly low omega-6 derivates (LA (p = 0.014) and AA (p = 0.025)) compared to control. LCPUFA parameters have shown to increase the risk in both conditions, particularly ALA ≤ 53 µmol/L in preeclampsia with OR 5.44, 95%CI 1.16–25.42 and preterm birth with OR 4.68, 95%CI 1.52–14.38. These findings suggest that severe preeclampsia and preterm birth have an imbalance in LCPUFA status.

Context. Several studies have shown a link between proinflammatory activity and the presence or deficit of some fatty acids. Inflammation is associated with several diseases including diabetes.Objective. To characterize and compare the fatty acids profiles in children with inaugural type 1 diabetes, diabetic children (at least 1 year after diagnosis), and healthy children.Design. Plasma fatty acids profiles in children with inaugural diabetes, children with noninaugural diabetes, and controls, all of whom were prepubescent with a BMI < 85th percentile, were evaluated.Results. Omega-3 fatty acid levels were higher in recently diagnosed subjects with diabetes than in controls. The ratio of omega-6/omega-3 fatty acids was higher in the control population. Omega-6 fatty acid levels were higher in the nonrecent diabetic subjects than in the children with recently diagnosed diabetes, and the levels were higher in the nonrecent diabetes group compared to the control group.Conclusion. Our findings showed higher levels of alpha-linolenic acid, EPA, and DHA, as well as mono- and polyunsaturated fatty acids, in diabetic children. These findings reinforce the importance of precocious nutritional attention and intervention in the treatment of diabetic children.

The study to find cocoa butter equivalent (CBE) as an alternative to cocoa butter (CB) from available and low cost commercial oils or fats has been increased recently. Current study investigates the blending of hard palm oil mid-fraction (PMF) with canola oil to produce high nutritional CBE using immobilized lipase from Rhizomucor miehei. The experiments were designed using Response Surface Methodology (RSM) to optimize the percentage of saturated-unsaturated-saturated (StUSt) triacylglycerols (TAGs). The experiment was performed at hard PMF concentration of 50 to 90% (w/w), lipozyme load between 5% and 10% (based on the weight of substrate) with a reaction time between 2 to 14 hours. The best reaction conditions to attain this target was 89.35% (w/w) of hard PMF concentration, 2 hours of reaction time, and 5% (based on the weight of substrate) of lipozyme load, resulting CBE which contains 64.44±1.18% of StUSt. The addition of canola oil improved the nutritional value of CBE which was marked by the higher percentage of linoleic acid (omega-6, 4.53±0.06%) and linolenic acid (omega-3, 0.74±0.14%) in CBE than CB (omega-6, 2.68±0.34%). Enzymatic interesterification was not altering fatty acid content in the CBE, especially linoleic acid (omega-6) and linolenic acid (omega-3) which was characterized by no significant difference (p > 0.05) between the fatty acid profile of initial mixture (before interesterification) and CBE (after interesterification).
