Background And Objective: Arachidonic acid (ARA) is essential for the fluidity, selective permeability, and flexibility of the cell membrane. It is an important factor for the function of all cells, particularly in the nervous system, immune system, and vascular endothelium. ARA is the second most common polyunsaturated fatty acid in the phospholipids of the nerve cell membrane after docosahexaenoic acid. ARA metabolites have many kinds of physiologic roles. The major action of ARA metabolites is the promotion of the acute inflammatory response, mediated by the production of pro-inflammatory mediators such as PGE2 and PGI2, followed by the formation of lipid mediators, which have pro-resolving effects. Another important action of ARA derivatives, especially COX, is the regulation of vascular reactivity through PGs and TXA2. There is significant involvement of ARA metabolites in neurodegenerative diseases, including Alzheimer's disease, Parkinson's disease, amyotrophic lateral sclerosis, and neuropsychiatric disorders. ARA derivatives also make an important contribution to acute stroke, global ischemia, subarachnoid hemorrhage, and anticoagulation-related hemorrhagic transformation.
Conclusion: In this review, we have discussed experimental and human study results of neurologic disorders related to ARA and its metabolites in line with treatment options.

Williams Syndrome (WS) is a rare neurodevelopmental disorder with a prevalence of 1 in 7500 to 1 in 20,000 individuals, caused by a microdeletion in chromosome 7q11.23. Despite its distinctive clinical features, the underlying metabolic alterations remain largely unexplored.

Objective: Despite its innumerable, invaluable and unique benefits to human development and welfare, consumption of the omega 6 polyunsaturated fatty acid, arachidonic acid (ARA) generates apprehension due to the association of its metabolites with allergy symptoms. Accordingly, it was deemed important to examine the impact of ARA supplementation on initiation and progress of peanut (PN)-induced allergy in mice of different MHC haplotypes.
Methods: Cohorts of BALB/c, C57BL/6, and outbred CD-1 mice were maintained two weeks before experimentation and until the end of the experiment on mouse food supplemented with equal amounts of milk powder containing 3 or 0 mg ARA/day/mouse, and then exposed to inhalation of 0 or 100 μg/mouse PN flour molecules twice for 4 weeks.

Vitamin D is required for healthy growth and development, but data on human milk vitamin D content is limited. We describe a liquid chromatography tandem mass spectrometry (LC-MS/MS) method for the analysis of vitamin D metabolites in human milk, and its application in samples collected on two consecutive days from women in rural Gambia. Vitamin D compounds were extracted from 1 mL of milk by liquid-liquid extraction and derivatised with 4-phenyl-1,2,4-triazoline-3,5-dione (PTAD) prior to analysis by LC-MS/MS.

Epidemiological studies have demonstrated exposure to cadmium ion (Cd) is significantly associated with the incidence and aggravation of nonalcoholic fatty liver disease (NAFLD) to non-alcoholic steatohepatitis (NASH). Cd exposure could alter lipid metabolism, and changed lipid metabolites are significantly associated with NASH. Arachidonic acid (ArA) is an omega-6 polyunsaturated fatty acid.

Objectives: This study examined the effect of a 4-week unsweetened cranberry beverage (CRAN) (317 mg polyphenols) versus placebo beverage (PLAC) ingestion (240 mL/day) on moderating exercise-induced changes in innate immunity.
Methods: Participants included 25 male and female non-elite cyclists. A randomized, placebo-controlled, double-blind crossover design was used with two 4-week supplementation periods and a 2-week washout period.
