Palm oil is the world’s most commonly used vegetable oil and extracted both from fruit and seed of palm tree. However, its high saturated fatty acid content raised controversies over consumption of the oil. Few scientific findings suggest it as a risk factor for cardiovascular disease and increased consumer’s awareness over healthy diet raised claim over it. So that, this article aimed to review literatures on palm oil extraction process and its positive and negative health consequences and besides suggest strategies for healthy diet. Literature search of relevant articles was conducted by using Google scholar, PubMed, Web of science, MEDLINE, World Health Organization library online catalogue, UNICEF library, Open access thesis and dissertations published between 2009 and 2021 explored. Study reports recommend that palmitic acid from vegetable source has less effect on blood total cholesterol and low density lipoprotein cholesterol level as compared to palmitic acid from animal source. In contrary tocotrienols of palm oil lowers blood bad cholesterol level by 7-38%. Moreover, palm oil triacylglycerol arrangement does not have a cardiovascular risk and evidences from available in vitro and in vivo studies are not sufficient enough to conclude palm oil as a causative agent for cardiovascular disease. For healthy diet consumers should avoid trans fatty acids, solid and semi solid oils. Finally, further studies recommended on mitigation strategies to minimize process induced toxicants of palm oil to acceptable level.

Oils and lipids are common food components and efficient sources of energy. Both the quantity and the quality of oils and lipids are important with regard to health and disease. Fatty acid ester of hydroxy fatty acid (FAHFA) is a novel lipid class that was discovered as an endogenous lipid; FAHFAs have shown anti-diabetic effects in a mammalian system. We analyzed the overall FAHFA composition in nut oils and other common oils: almond (raw, roasted), walnut, peanut, olive, palm, soybean, and rapeseed oils. We developed a method of liquid chromatography coupled with electrospray ionization triple quadrupole mass spectrometry (LC-ESI/MS/MS) for a comprehensive target analysis of FAHFAs. The analysis revealed wide variation in the FAHFA profiles (15 compounds and 62 peaks). For 7-11 compounds of FAHFA, a total level of 8-29 pmol/mg oil was detected in nuts oils; for 11 compounds, 4.9 pmol/mg oil was detected in olive oil, and for 4-9 compounds, < 2 pmol/mg oil was detected in palm, soy, and rapeseed oils. The major FAHFAs were FAHFA 36:3, FAHFA 36:2, and FAHFA 36:4 in nut oil, FAHFA 36:2, FAHFA 34:1, and FAHFA 36:1 in olive oil, and FAHFA 32:1, FAHFA 34:0, FAHFA 36:0, and FAHFA 36:1 in all of the common oils. The composition of FAHFAs in nut oils is mainly unsaturated fatty acids, whereas those in olive oil are unsaturated fatty acids and saturated fatty acids. The composition of FAHFAs in common oils was mainly saturated fats. This is the first report to demonstrate the quality and quantity of the FAHFAs in the nut oils. Nuts have been described to be a great source of many nutrients and to be beneficial for our health. Our present findings comprise additional evidence that the intake of nuts in daily diets may prevent metabolic and inflammatory-based diseases.

Oxidative stress occurs due to the imbalance amount of the free radicals and antioxidants in human body which often associated with numerous chronic diseases. The antioxidant properties of red palm-pressed mesocarp olein (PPMO) have not been widely studied. Therefore, antioxidant properties of PPMO relative to commercially available edible oils, namely red palm olein (RPO), palm olein (PO), extra virgin olive oil (OO) and extra virgin coconut oil (CNO) were studied. PPMO exhibited significant higher phytonutrients which more than 2-fold compared to the edible oils. Overall, antioxidant screening indicated that PPMO has significantly higher antioxidant activities than RPO, PO and CNO in term of DPPH, H₂O₂, NO scavenging and FIC; and significantly higher H₂O₂ and FIC than OO. The outcomes of this study reveal that PPMO is as good as commercially available edible oil, also a good source for food applications and dietary nutritional supplements. More importantly, the utilization of PPMO could mitigate oil palm waste problem and results in positive environmental impact.

This work aims to study the influence of olive fruit maturity on physicochemical properties and antioxidant activity which determine the quality of virgin olive oils (VOO). According to the results, the values of all parameters were within the range specified by the Codex Alimentarius (2017). With the increase of fruit maturity, the oil content continued to increase until reached the maximum value (20.05%) in the 7th maturity (M7). K₂₃₂, K₂₇₀ and peroxide value (PV) decreased with the increase of maturity, while ΔK increased linearly with the increase of maturity. Free fatty acidity (FFA) first decreased and then increased, until reached the maximum value of (0.52 ± 0.03) % in M7. The total polyphenols (TP) and total flavonoids (TF) that characterized the antioxidant properties of olive oil increased with the increase of fruit maturity, which indicated that the oxidative stability (OS) of VOO of ‘Cornicabra’ increased with the increase of fruit maturity. The oleic acid (C18:1) content remained above 70 % and reached the maximum of (76.68 ± 0.17) % at M7. The values of monounsaturated fatty acids (MUFA) / polyunsaturated fatty acids (PUFA) and oleic acid (C18:1) / linoleic acid (C18:2) showed a decreasing trend with the maturity stage. Principal component analysis (PCA) showed that the quality of FFA, PV, K₂₃₂, K₂₇₀, TP, TF and OS were higher at the 5th maturity (M5), the quality of fatty acid were higher at M7. It can be seen from the analysis that the olive fruit maturity was an important parameter to characterize and distinguish olive oil.

In this study, the effect of altitude on oil amounts, antioxidant activity, polyphenol content and mineral contents of Acacia seeds collected from two different locations (up to 1100 m above sea level) was investigated. Total carotenoid and flavonoid contents of Acacia seeds were detected as 0.76 (Konya) and 1.06 µg/g (Taşucu-Mersin) to 1343.60 (Konya) and 184.53 mg/100 g (Taşucu-Mersin), respectively. Total phenol contents and antioxidant activity values of Acacia seeds were identified as 255.11 (Konya) and 190.00 mgGAE/Taşucu-Mersin) to 64.18% (Konya) and 75.21% (Taşucu-Mersin), respectively. The oils extracted from Acacia seeds in Konya and Mersin province contained 62.70% and 70.39% linoleic, 23.41% and 16.03% oleic, 6.45%and 6.04% palmitic and 2.93% and 4.94% stearic acids, respectively. While 3,4-dihydroxybenzoic acid amounts of seeds are determined as 3.89 (Konya) and 4.83 mg/100 g (Taşucu-Mersin), (+)-catechin contents of Acacia seeds were identified as 3.42 (Konya) and 9.51 mg/100 g (Taşucu-Mersin). Also, rutintrihydrate and ferulic contents of Acacia seeds were found as 23.37 (Konya) and 11.87 mg/100 g (Taşucu-Mersin) to 14.74 mg/100 g (Konya) and 1.12 mg/100 g (Taşucu-Mersin), respectively. Acacia seeds collected from Konya and Mersin contained 4003.75 and 3540.89 mg/kg P, 9819.12 and 16175.69 mg/kg K, 4347.47 and 5078.81 mg/kg P, 2195.77 and 2317.90 mg/kg Mg, 1015.75 and 2665.60 mg/kg S and 187.53 and 905.52 mg/kg Na, respectively.

Refined red palm-pressed mesocarp olein (PPMO) is recovered from palm-pressed mesocarp fiber, which is a by-product from palm oil mill. Its utilization in food industry is extremely limited even though it contains various phytonutrients. Thus, this study aimed to evaluate its toxicity effects by using the male Sprague-Dawley rat model. The rats were administered with a single dose of 2 g/kg PPMO in an acute toxicity study while administered with 2, 1, or 0.5 g/kg PPMO daily for 28 days in a sub-chronic toxicity study. The mortality, oral LD₅₀ value, clinical observation, body and organ weight, hematological and biochemical analyses, pathological and histopathological examinations were assessed. The overall outcomes indicated that PPMO is non-toxic up to 2 g/kg and considered safe to be used in food application, especially as functional food ingredient and supplement attributed to its phytonutrients. Besides, this study provides an insight in alternative utilization of the wastes from palm oil mill.

The present study was designed to provide information regarding the influences of pH and inorganic salts on the surface activity of the amido Gemini amine oxide surfactants, the formula of which was C _n H_{2 n +1}CONH(CH₂)₂N⁺O^-(CH₃)-(CH₂)₂-(CH₃)N⁺O^-(CH₂)₂NHCOC _n H_{2 n +1} (n=11, 13, 15, and 17). Their biodegradability was also investigated. The results showed that the critical micelle concentration (CMC) and the corresponding surface tension (γ_CMC) changed regularly with the increase of the mass concentration of NaCl and CaCl₂. The optimal CMC and γ_CMC can be obtained by adjusting the inorganic salt content. Besides, the CMC near the isoelectric point of the surfactant is higher than the CMC within the isoelectric point. Furthermore, the biodegradability test revealed that the prepared surfactants had good biodegradability which was above 96% after 7 days.

We report on the synergic effect of surfactants and chelating agents on the mechanism to remove stubborn keratin grime (keratin-Ca), which is bound with calcium ions and one of the most difficult grimes to remove, in order to make it easier to clean bathtubs in less time and with less scrubbing. Our approach was to focus on keratin swelling, which we achieved by applying aqueous solutions with chelating agents and anionic surfactants, the combination of which greatly improved the swelling ratio, resulting in quick, easy removal of keratin-Ca with water rinsing and little scrubbing. For the swelling process, we added chelating agents and anionic surfactants to swell the keratin-Ca by both capturing calcium ions and improving solution permeation. Furthermore, we measured the structural change of the keratin-Ca during swelling by TD-NMR and confirmed that a certain combination of chelating agent and anionic surfactant improved swelling by affecting not only the amorphous part such as the keratin matrix, but also the crystalline part such as the intermediate filaments (IFs).

Surface treatment of wood surface is an effective method to improve the physical properties. The friction dynamics of wood coated with vegetable oil were evaluated and compared to wood treated with polyurethane and untreated wood. The kinetic friction coefficient, µ _k , was 0.39±0.01, which was smaller than the values for polyurethane-treated wood and untreated oak. The effect of the surface treatment was also observed in the dependence of velocity on the friction coefficient. The friction profile of the wood surface treated with vegetable oil was similar to that of untreated wood, and the friction coefficient was nearly constant, except in the static friction region of sliding out. These results suggest that wood treated with vegetable oil is suitable for inducing a smooth feel.

Lung cancer has the highest incidence rate among malignant tumors all over the world, and it is also the leading cause of death. In this present research, we aimed to evaluate the anti-cancer activity of the Populus nigra extract against the lung cancer and study the genome evolution of the Populus nigra. Firstly, the inhibitory activity of the Populus nigra extract on the NCI-H292 lung cancer cell viability was determined with Cell Counting Kit-8 (CCK-8) assay. The trans-well assay was conducted and the influence of the Populus nigra extract on the NCI-H292 lung cancer cell migration and invasion ability was determined. In addition to this, the chloroplast (cp) genome of Populus nigra was sequenced with high-throughput Illumina pair-end sequencing, which was a classical useful model for genome evolution assessment. The CCK-8 and trans-well assay indicated the Populus nigra extract exhibited excellent inhibitory activity on the NCI-H292 lung cancer cell viability, migration and invasion ability. The circular cp genome of the Populus nigra was 156,354 bp in size, including a large single-copy (LSC) region of 84,528 bp and a small single-copy (SC) region of 16,564 bp, which were separated by two inverted repeat (IR) regions (38,612 bp each). A total of 132 genes were predicted, including 8 ribosomal RNAs (rRNAs), 37 transfer RNAs (tRNAs), and 90 protein-coding genes (PCGs). Furthermore, phylogenetic analysis revealed that Populus nigra has the closest relationship with Populus alba var. pyramidalis. In addition to Populus alba var. pyramidalis, Populus adenopoda and Populus tomentosa are also has closely relationship with Populus nigra.

Genetic studies including the quest, cloning and expression of genes encoding proteins responsible for various vital physiological processes and beneficial characteristics of economic perspective have made the biotechnology research progressively auspicious. Due to its great zootechnical and industrial importance somatotropin gene have been cloned from various animal species. Current study was designed to clone mature ovine growth hormone complementary DNA (oGH cDNA) of a sheep breed, Kajli and carry out over expression studies of cloned GH cDNA in a suitable prokaryotic expression system. Sheep GH cDNA was cloned in T/A (thymine / adenine) vector with signal peptide and confirmed by nested polymerase chain reaction (PCR) and restriction digestion. The gene was then ligated in pLEX expression vector and restricted plasmids showed a fragment insert of ~ 600 bps. Restriction analysis confirmed positive clones, were induced for protein expression analysis. The pET vectors (plasmid for expression by T7 RNA polymerase) have an isopropylthio-β-galactoside (IPTG) inducible strong T7 promoter and Escherichia coli expression strain of BL21 (DE3) pLysS contains DNA fragment from T7 phage which harbors RNA polymerase. Therefore, for expressing recombinant proteins, cells were induced with various IPTG concentrations to optimize expression levels. Cells were induced with different IPTG concentrations (0.1 to 0.8 mM) followed by sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE). Results indicated maximum expression level of oGH at 5 hrs after induction of cells with 0.3 mM IPTG concentration with a molecular weight of 22 kDa. As for as cellular localization of protein is concerned accumulation of expressed oGH is observed in inclusion bodies. The successful expression of the cloned GH cDNA of sheep confirmed the functional viability of the clone. The above mentioned technique of genetic engineering has provided to boost the dairy industry by the production of large quantities of recombinant bovine somatotropin (rbST).

The antiadipogenic activity of conjugated linoleic acids (CLA) in the form of phosphatidylcholine-bound (CLA-PC) or free fatty acids (FFA; CLA-FFA) was evaluated using 3T3-L1 adipocytes. Phosphatidylcholine from soya (soy-PC) was used as the comparison of PC form. Both the lipid accumulation and activity of glycerol-3-phosphate dehydrogenase were measured to determine lipogenesis, whereas the glycerol content was measured to evaluate lipolysis. The CLA uptake also measured to find out the utilization of CLA by the cells. As a results, lipid accumulation in 3T3-L1 adipocytes was inhibited in a dose-dependent manner following treatment with CLA-PC (50-400 μM). Both CLA-PC and soy-PC significantly suppressed lipid accumulation compared with CLA-FFA, even though the amount of CLA in CLA-PC was a half than CLA-FFA. The CLA uptake of PC form was superior to FFA form, however, no difference was noted between CLA-PC and soy-PC. These forms exerted their antiadipogenic activity via the suppression of lipogenesis, and not by increasing lipolysis. Short-term treatment, especially in the middle stage of differentiation, was more effective than long-term treatment; especially for CLA-FFA. The antiadipogenic effect of CLA-PC was partially attributed to the chemical structure of the PC molecule. These results provide important information for the utilization of physiologically functional fatty acids and particularly CLA in the food and medical fields.

Sterculia tragacantha (ST) Lindl leaf is commonly used locally in the management of diabetes mellitus (DM) and its complications. This study was aimed at assessing the valuable effects of ST leaf on streptozotocin-diabetic cardiomyopathy (DCM). Streptozotocin was administered intraperitoneally to the experimental animals to induce DM, and hence, placed on different doses of ST for 14 days. Thereafter, on the 15^th day of the experiment, the animals were euthanized, and a number of cardiomyopathy indices were investigated. The diabetic rats exhibited a momentous increase in hyperlipidemia, lipid peroxidation as well as a significant (p < 0.05) decline in antioxidant enzyme activities. The serum creatine kinase MB (CK-MB), C-reactive protein (CRP), cardiac troponin I, tumour necrosis factor-alpha (TNF-α) and urotensin II expression revealed a significant (p < 0.05) upsurge in diabetic rats. Also, the expression of GLUT4 and fatty acid-binding protein 3 (FABP3) were significantly (p < 0.05) reduced in diabetic rats. However, at the conclusion of the experimental trial ST significantly (p < 0.05) attenuated hyperlipidemia, oxidative stress biomarkers by augmenting the antioxidant enzyme activities and decrease in lipid peroxidation, ameliorated CK-MB, CRP, cardiac troponin I, TNF-α, and urotensin-II levels, and improved GLUT4 and FABP3 expressions. Similarly, the administration of ST prevented histological alterations in the heart of diabetic animals. Therefore, the obtained results suggest that ST could mitigate DCM in streptozotocin-induced diabetic rats.

Atherosclerosis (AS) is a cardiovascular disease that arise due to dysfunction of lipid deposition and metabolism. AS is causes the mortality and morbidity worldwide. Sinomenine isolated from the Sinomenium acutum is used extensively against the various cardiac diseases in China. However, the anti-atherosclerosis effect of sinomenine still not explore. In this study, we explore the cardioprotective and anti-atherosclerosis effect of sinomenine against Vitamin D3 and High fat induced atherosclerosis in rats. Sprague Dawley (SD) rats were used in this study. The rats were received the vitamin D (60000) and High fat diet to induce the atherosclerosis and divided into groups and received the oral administration of sinomenine (2.5, 5 and 10 mg/kg) and simvastatin (5 mg/kg). Body weight, organ weight and biochemical parameters were estimated. The mRNA expression of MyD88, TLR4, NF-κB and IκB were estimated. Sinomenine treated rats significantly (p<0.001) suppressed the body weight and modulated the organ weight (hepatic, renal and heart). Sinomenine significantly (p<0.001) decreased the level of triacylglycerols (TG), low density lipoprotein cholesterol (LDL-c), total cholesterol (TC), very low-density lipoprotein cholesterol (VLDL-c) and augmented the level of high-density lipoprotein cholesterol (HDL-c). Sinomenine treatment also reduced the level of atherogenic index (TC/HDL-c and LDL-c/HDL-c). Sinomenine treatment decrease the ratio of HMG CoA/Mevalonate and level of collagen and total protein. Sinomenine significantly (p<0.001) altered the level of heart parameters, antioxidant parameters and inflammatory cytokines. Sinomenine significantly (p<0.001) reduced the expression of MyD88, TLR4, NF-κB and IκB. Taken together, sinomenine exhibited the protective effect against the atherosclerosis via alteration of TLR4/NF-κB signaling pathway.

The pathogenic mechanism of dementia is still unknown, and the fundamental treatment remains to be established. Thus, there is growing interest in preventing dementia through diet. One of the functional ingredients attracting attention is docosahexaenoic acid. We conducted a 12-month, randomized, double-blind, placebo-controlled clinical trial in healthy elderly Japanese individuals with a Mini-Mental State Examination score of 28 or higher at baseline using a docosahexaenoic acid-enriched milk beverage containing 297 mg docosahexaenoic acid and 137 mg eicosapentaenoic acid. Consumption of a docosahexaenoic acid-enriched milk beverage increased the fatty acid levels of docosahexaenoic acid and eicosapentaenoic acid in erythrocyte membranes, which was the primary outcome of this study. Moreover, intake of this beverage prevented age-related cognitive decline and decreased serum bone resorption marker levels. Our data demonstrate that, even at a low dose, long-term daily intake of docosahexaenoic acid prevents dementia and may show beneficial effect on bone health.
