Phosphatidylserine: A comprehensive overview of synthesis, metabolism, and nutrition.

Phosphatidylserine (PtdS) is classified as a glycerophospholipid and a primary anionic phospholipid and is particularly abundant in the inner leaflet of the plasma membrane in neural tissues. It is synthesized from phosphatidylcholine or phosphatidylethanolamine by exchanging the base head group with serine, and this reaction is catalyzed by PtdS synthase-1 and PtdS synthase-2 located in the endoplasmic reticulum. PtdS exposure on the outside surface of the cell is essential for eliminating apoptotic cells and initiating the blood clotting cascade. It is also a precursor of phosphatidylethanolamine, produced by PtdS decarboxylase in bacteria, yeast, and mammalian cells. Furthermore, PtdS acts as a cofactor for several necessary enzymes that participate in signaling pathways. Beyond these functions, several studies indicate that PtdS plays a role in various cerebral functions, including activating membrane signaling pathways, neuroinflammation, neurotransmission, and synaptic refinement associated with the central nervous system (CNS). This review discusses the occurrence of PtdS in nature and biosynthesis via enzymes and genes in plants, yeast, prokaryotes, mammalian cells, and the brain, and enzymatic synthesis through phospholipase D (PLD). Furthermore, we discuss metabolism, its role in the CNS, the fortification of foods, and supplementation for improving some memory functions, the results of which remain unclear. PtdS can be a potentially beneficial addition to foods for kids, seniors, athletes, and others, especially with the rising consumer trend favoring functional foods over conventional pills and capsules. Clinical studies have shown that PtdS is safe and well tolerated by patients.

Cottonseed oil: A review of extraction techniques, physicochemical, functional, and nutritional properties.

Seed oils are the richest source of vitamin-E-active compounds, which contribute significantly to antioxidant activities. Cottonseed oil (CS-O) is attaining more consideration owing to its high fiber content and stability against auto-oxidation. CS-O has gained a good reputation in the global edible oil market due to its distinctive fatty acid profile, anti-inflammatory, and cardio-protective properties. CS-O can be extracted from cottonseed (CS) by microwave-assisted extraction (MAE), aqueous/solvent extraction (A/SE), aqueous ethanol extraction (A-EE), subcritical water extraction, supercritical carbon dioxide extraction (SC-CO2), and enzyme-assisted extraction (E-AE). In this review, the importance, byproducts, physicochemical characteristics, and nutritional profile of CS-O have been explained in detail. This paper also provides a summary of scientific studies existing on functional and phytochemical characteristics of CS-O. Its consumption and health benefits are also deliberated to discover its profitability and applications. CS-O contains 26-35% saturated, 42-52% polyunsaturated, and 18-24% monounsaturated FA. There is approximately 1000 ppm of tocopherols in unprocessed CS-O, but up to one-third is lost during processing. Moreover, besides being consumed as cooking oil, CS-O discovers applications in many fields such as biofuel, livestock, cosmetics, agriculture, and chemicals. This paper provides a comprehensive review of CS-O, its positive benefits, fatty acid profile, extraction techniques, and health applications.HighlightsCS-O is a rich source of exceptional fatty acids.Various techniques to extract the CS-O are discussed.Numerous physicochemical properties of CS-O for the potential market are assessed.It has a wide range of functional properties.Nutritional quality and health benefits are also evaluated.

Comparative Evaluation of the Treatment Outcomes of Pulpotomy in Primary Molars Using Mineral Trioxide Aggregate and 3Mixtatin: A Randomized Clinical Trial.

Objective: To evaluate and compare the efficacy of 3Mixtatin and mineral trioxide aggregate (MTA) for pulpotomy in primary teeth by assessment of pre- and postoperative clinical and radiographic data. Materials and methods: In this randomized clinical trial, 50 primary molars from 48 healthy children aged 3-8 years were randomly allocated into two groups. Deep dentinal caries approaching pulp in primary teeth were treated by pulpotomy using MTA and 3Mixtatin. Over the intervening period, restoration was done using glass ionomer cement (GIC) and composite, followed by stainless steel crown. Clinical and radiographic examinations were conducted at 3, 6, and 12 months after treatment. The data were compared using Chi-squared test at a significance level of 0.05. Results: A total of 39 patients were available for follow-up study. By the end of 12 months, the overall success rates were 95.5% in MTA and 91.3% in 3Mixtatin. No statistically significant difference was found among the outcomes of MTA and 3Mixtatin groups (p > 0.05). Conclusion: Radiographic and clinical outcomes in MTA and 3Mixtatin group in this study show 3Mixtatin as a suitable alternative for pulpotomy medicament in primary teeth.
