UNASSIGNED: Monitoring noncommunicable diseases is regarded as a critical concern that has to be managed in order to avoid a wide variety of complications such as increasing blood lipid levels known as dyslipidemia. Statin drugs, mostly, Rosuvastatin (RSV) was investigated for its effectiveness in treating dyslipidemia. However, reaching the most efficient treatment is essential and improving the effect of RSV is crucial. Therefore, a combination therapy was a good approach for achieving significant benefit. Although RSV is hydrophobic, which would affect its absorption and bioavailability following oral administration, overcoming this obstacle was important.
UNASSIGNED: To that end, the purpose of the present investigation was to incorporate RSV into certain lipid-based nanocarriers, namely, nanostructured lipid carrier (NLC) prepared with virgin coconut oil (CCO).
UNASSIGNED: The optimized RSV-NLC formula was selected, characterized and examined for its in vitro, kinetic, and stability profiles. Eventually, the formula was investigated for its in vivo hypolipidemic action.
UNASSIGNED: The optimized NLC formulation showed a suitable particle size (279.3±5.03 nm) with PDI 0.237 and displayed good entrapment efficiency (75.6±1.9%). Regarding in vitro release, it was efficiently prolonged for 24 h providing 93.7±1.47%. The optimized formula was established to be stable after 3 months storage at two different conditions; 4°C and 25°C. Importantly, including CCO in the development of RSV-NLC could impressively enhance lowering total cholesterol level in obese rat models, which endorse the potential synergistic action between RSV and CCO.
UNASSIGNED: The study could elucidate the impact of developing NLC using CCO for improving RSV anti-hyperlipidemic activity.

A recent pilot study in amyotrophic lateral sclerosis (ALS) patients analyzed the effect of a Mediterranean diet (MeDi) supplemented with nicotinamide riboside (NR, a NAD+ promoter), pterostilbene (PTER, a natural antioxidant) and/or coconut oil on anthropometric variables in ALS patients. The results suggested that the MeDi supplemented with NR, PTER and coconut oil is the nutritional intervention showing the greatest benefits at anthropometric levels. Over the last 30 years, glucose intolerance has been reported in ALS patients. Thus, suggesting that an alternative source of energy may be preferential for motor neurons to survive. Ketone bodies (KBs), provided through a MeDi with a lower carbohydrate content but enriched with medium chain triglycerides, could be a therapeutic alternative to improve the neuromotor alterations associated with the disease. Nevertheless, the use of a coconut oil-supplemented diet, as potentially ketogenic, is a matter of controversy. In the present report we show that a MeDi supplemented with coconut oil increases the levels of circulating KBs in ALS patients.

A protein mixture was prepared using a blend of soybean protein isolate, soybean protein concentrate, and wheat protein through high-moisture extrusion. This study investigated the effects of soybean oil/coconut oil additions (2%, 5%, and 8%) on the physiochemical properties of a soy protein-wheat protein mixture subjected to high-moisture extrusion. The protein extrudates underwent assessment for textural properties, fiber degree, sensory evaluation, microstructure, protein solubility, and protein secondary structure. The findings indicated that plant oils significantly reduced the hardness, springiness, and chewiness of the extrudates, and 5% plant oil significantly increased the fiber degree of the extrudates. In addition, the highest fiber degree and sensory evaluation score were achieved with 5% coconut oil. Observation of the macro- and microstructure indicated that the presence of unsaturated fatty acids in soybean oil did not benefit the improvement of the fibrous structure of protein extrudates during high-moisture extrusion processing. SDS-PAGE and FTIR results revealed that coconut oil, rich in saturated fatty acids, caused the clustering of medium- and low-molecular-weight subunits in texturized protein. Additionally, coconut oil elevated the ratio of 11S protein subunits containing sulfur-based amino acids and facilitated a shift from β-turn to β-sheet. The inclusion of plant oils increased the development of hydrogen and disulfide bonds, resulting in a denser, fibrous structure. DSC demonstrated that plant oils reduced the thermal stability of the texturized proteins but enhanced the order of protein structure.

In this study, fractionated palm stearin, oleic acid, and linoleic acid were selected as the base materials to prepare human milk fat substitutes (HMFS) rich in OPO and OPL by enzymatic acidolysis combined with physical blending. Under optimum conditions, contents of OPO, OPL, and sn-2 palmitic acid in the OPO and OPL-rich triacylglycerols (TAGs) were higher than that in commercial OPO-rich TAGs, with values of 37.25%, 28.12%, and 79.44%, respectively. Physical blending the OPO and OPL-rich TAGs (47%), bovine milk fat (18%), sunflower oil (13%), coconut oil (13%), corn oil (8%), and palm oil (1%) can obtain HMFS with a fat composition that like HMF. The fatty acid, sn-2 saturated fatty acid, and TAG contents of HMFS were within the lower and upper limit of HMF. The lipolysis degree of infant formula (IF) with HMFS as fat source is 9.0% higher than that of commercial plant oil-based infant formula (PIF), and 3.4% lower than that of human milk. IF with HMFS as fat source released less saturated free fatty acids and more saturated monoacylglycerols during digestion than that of PIF, which would help improve the IF fat utilization by infants.

Lauric acid, a major component of coconut oil, has been studied for its various health benefits over the years. Lauric acid is a medium-chained fatty acid with several potential biomedical applications based on its antimicrobial action, capacity for drug delivery, tissue engineering scaffolds, and cleansing capabilities. Various studies are carried out in vitro and in vivo using experimental animals, such as rats, shedding light on the efficacy of lauric acid. The studies related to lauric acid were brought under one umbrella and emphasized the need for further research to explore the efficacy of lauric acid in human health. This review aims to scientifically assess the reported data and present a narrative review on lauric acid in medicine.

The tire industry needs to become more sustainable to reduce pollution and fight climate change. Replacing fossil ingredients in a tire-tread compound with bio-based alternatives is an approach to create a more sustainable product. For instance, the plasticizer can be replaced, which is a petroleum-based ingredient used in relatively high amounts in the rubber. This approach was followed in the current study. Three plant-based plasticizers were selected as potential substitutes for treated distillate aromatic extract (TDAE) in a simplified tire-tread compound formulation, namely, sunflower oil, coconut oil, and cardanol. Additionally, squalane was used as a TDAE replacement to further investigate the possible interactions between plasticizers and other compound ingredients. Squalane (C30H62) is a fully saturated substance, containing six methyl groups but no additional chemical functional groups. Therefore, it was expected that squalane would result in limited interactions within the studied system. All alternatives to TDAE showed an increased cure rate and decreased scorch time, except squalane. This indicates that the three bio-based plasticizers might interact with the vulcanization system. For example, they could function as an additional coactivator of the curing system and/or shield the silica surface. A severe decrease in maximum torque and an increase in elongation at break were obtained for cardanol and sunflower oil. Both plasticizers also resulted in lower crosslink densities compared to the other compounds. A model study with the bio-plasticizers and sulfur verified that the unsaturation in the cardanol and sunflower oil reacted with the crosslinking agent. This leads to less sulfur available for the curing reaction, explaining the low maximum torque. The tan δ curves showed that all replacements resulted in a decrease in the glass transition temperature of the compound. Although all oil alternatives displayed promising results, none of them are suitable as a direct substitute for TDAE in a tire-tread compound due to its ability to interact additionally with other rubber ingredients and contribute in this form to the reinforcement of the compound.

The effects of oil type, emulsifier type, and emulsion particle size on the texture, gel strength, and rheological properties of SPI emulsion-filled gel (SPI-FG) and TFSP emulsion-filled gel (TFSP-FG) were investigated. Using soybean protein isolate or sodium caseinate as emulsifiers, emulsions with cocoa butter replacer (CBR), palm oil (PO), virgin coconut oil (VCO), and canola oil (CO) as oil phases were prepared. These emulsions were filled into SPI and TFSP gel substrates to prepare emulsion-filled gels. Results that the hardness and gel strength of both gels increased with increasing emulsion content when CBR was used as the emulsion oil phase. However, when the other three liquid oils were used as the oil phase, the hardness and gel strength of TFSP-FG decreased with the increasing of emulsion content, but those of SPI-FG increased when SPI was used as emulsifier. Additionally, the hardness and gel strength of both TFSP-FG and SPI-FG increased with the decreasing of mean particle size of emulsions. Rheological measurements were consistent with textural measurements and found that compared with SC, TFSP-FG, and SPI-FG showed higher G\' values when SPI was used as emulsifier. Confocal laser scanning microscopy (CLSM) observation showed that the distribution and stability of emulsion droplets in TFSP-FG and SPI-FG were influenced by the oil type, emulsifier type and emulsion particle size. SPI-stabilized emulsion behaved as active fillers in SPI-FG reinforcing the gel matrix; however, the gel matrix of TFSP-FG still had many void pores when SPI-stabilized emulsion was involved. In conclusion, compared to SPI-FG, the emulsion filler effect that could reinforce gel networks became weaker in TFSP-FG.

BACKGROUND: High incidence of cardiovascular disease (CVD) in South Asia is linked to genetic predisposition and diets high in saturated fatty acids (SFAs). Increased CVD prevalence correlates with rising palm oil consumption in some South Asian countries, where coconut oil and palm olein oil are primary SFA sources.
OBJECTIVE: Compare the effects of coconut oil and palm olein oil on serum lipoprotein lipids and biochemical parameters in healthy adults.
METHODS: A sequential feeding crossover clinical trial with two feeding periods of 8 weeks each was conducted among 40 healthy adults. Participants were provided palm olein oil in the first feeding period followed by coconut oil with a 16-week washout period in between. The outcomes measured were the difference in serum low-density lipoprotein cholesterol (LDL-C), total cholesterol (TC) and high-density lipoprotein cholesterol (HDL-C), TC/HDL-C ratio, triglycerides (TG), very-low-density lipoprotein cholesterol (VLDL-C), fasting plasma glucose (FPG), and liver enzymes.
RESULTS: Thirty-seven participants completed the study. LDL-C decreased by 13.0 % with palm olein oil (p < 0.001) and increased by 5.6 % with coconut oil (p = 0.044), showing a significant difference (p < 0.001). TC decreased by 9.9 % with palm olein oil (p < 0.001) and increased by 4.0 % with coconut oil (p = 0.044).
CONCLUSIONS: Palm olein oil consumption resulted in more favorable changes in lipid-related CVD risk factors (TC, LDL-C, TC:HDL-C, and FPG) compared to coconut oil. Clinical Trial Registry number and website where it was obtained: (SLCTR/2019/034); https://slctr.lk/trials/slctr-2019-034.

In this study, we conducted an 8-week feeding trial to investigate the effects of replacing fish oil (FO) with coconut oil (CO) on the growth performance, blood components, tissue fatty acid (FA) profile, and mRNA levels of genes related to lipid metabolism in the liver of the orange-spotted grouper (Epinephelus coioides). Five isolipidic and isoproteic diets were formulated through increasing the CO levels (0, 25%, 50%, 75%, and 100%, respectively). Triplicate groups of twenty-five fish (initial wet weight of about 22.4 g/fish) were fed one of the diets twice daily to apparent satiety. The 25% CO diet had the highest growth rate and feed utilization, and the 100% CO diet exhibited a comparable growth and feed utilization with that of the control diet, indicating a suitable FO substitute. Moreover, the hepatosomatic index, intraperitoneal fat rate, liver lipid content, as well as the serum HDL-C content and ALT activity had positive linear and/or quadratic responses, but the serum TC and LDL-C contents exhibited the opposite trend, with an increasing CO inclusion level. The FA profile in the liver and muscle generally mirrored the FA profile in the feed. Furthermore, the mRNA levels of the fas, acc, g6pd, srebp-1c, and δ6fad genes in the liver had positive linear and/or quadratic responses, but the mRNA levels of elovl 4 and elovl 5 had the opposite trend, with increasing dietary CO inclusion levels. When compared with the control diet, 25% and 50% CO diets up-regulated the mRNA levels of cpt 1, while the 75% and 100% CO diets down-regulated its mRNA levels. The hsl and atgl were down-regulated through the addition of dietary CO. The mRNA level of lpl was not affected by dietary treatments. Results showed that CO could completely replace FO without affecting growth performance, but high CO will lead to the significant liver lipid deposition and lower LC-PUFAs contents of fish flesh.

The effectiveness of Oil Pulling Therapy (OPT) with coconut (CO) and sesame oil (SO) on gingivitis patients is of interest. Forty patients were randomly distributed into group A and B for CO and SO respectively. Participants of group A were explained in detail about the OPT with CO and group B with SO along with their routine oral hygiene practice for 30 days. The mean plaque index of CO and SO reduced from 1.5 to 1.32 and 1.65 to 1.36 (p<0.05) respectively after 30 days. The mean gingival index of CO and SO declined from 1.12 to 0.9 and 1.1 to 0.81 respectively after 30 days (p<0.05) compared to initial scores. The mean no. of colonies in the case of CO and SO declined from 35.8 x 103 to 32.4 x 103 and 6.8 x 103 to 34.6 x 103 after 30 days (p<0.05). OPT reduced plaque and gingivitis, according to the results of one month. Hence, we must increase awareness about oil pulling, as this home therapy can prevent gingival diseases in countries with limited resources like ours.
