Introduction: The levels of docosahexaenoic acid (DHA, 22:6n-3) and arachidonic acid (AA, 20:4n-6) are critical for the normal structure and function of the brain. Trans fatty acids (TFA) and the source of the dietary fatty acids (FA) interfere with long-chain polyunsaturated fatty acids (LC-PUFA) biosynthesis.
Objectives: The aim of this study was to investigate the effect of TFA supplementation in diets containing different proportions of n-9, n-6, and n-3 FA on the brain FA profile, including the retention of TFA, LC-PUFA levels, and n-6/n-3 PUFA ratios. These parameters were also investigated in the liver, considering that LC-PUFA are mainly bioconverted from their dietary precursors in this tissue and transported by serum to the brain. Also, stearoyl-CoA desaturase-1 (SCD1) and sterol regulatory element-binding protein-1c (SREBP-1c) gene expressions were evaluated.
Methods: Male CF1 mice were fed (16 weeks) diets containing different oils (olive, corn, and rapeseed) with distinct proportions of n-9, n-6, and n-3 FA (55.2/17.2/0.7, 32.0/51.3/0.9, and 61.1/18.4/8.6), respectively, substituted or not with 0.75% of TFA. FA composition of the brain, liver, and serum was assessed by gas chromatography.
Results: TFA were incorporated into, and therefore retained in the brain, liver, and serum. However, the magnitude of retention was dependent on the tissue and type of isomer. In the brain, total TFA retention was lower than 1% in all diets.
Discussion: Dietary n-3 PUFA decreased TFA retention and increased DHA accretion in the brain. The results underscore the importance of the type of dietary FA on the retention of TFA in the brain and also on the changes of the FA profile.

Background: Prostaglandin analogs are first-line treatments for open-angle glaucoma due to their proven efficacy in reducing intraocular pressure. Despite their topical administration, systemic adverse drug Events (ADEs) have been reported. This study investigates the systemic ADEs associated with topical prostaglandin analogs using the United States Food and Drug Administration (USFDA) Adverse Drug Event Reporting System (AERS) database.

This study aimed to investigate the temporal accumulation of odor fatty acids (OFAs) in the dorsal subcutaneous adipose tissue, and uncover their dynamic regulatory metabolic pathways from the transcriptomic perspective in lambs from birth to market. Thirty-two Hulun Buir lambs were selected and randomly assigned to four different sampling stages following their growth trajectories: neonatal (day 1), weaning (day 75), mid-fattening (day 150), and late-fattening (day 180) stages. Results indicated that the contents of three OFAs increased progressively as lambs matured, with the most drastic change occurred at mid-fattening vs.

Introduction: Previous randomised controlled trials (RCTs) have indicated a protective role of pregnancy supplementation with fish oil and high-dose vitamin D, respectively, on offspring asthma, infections and several other disorders in early childhood. However, current evidence is not considered sufficient for recommending these supplements in pregnancy. In two RCTs, we aim to investigate whether these protective effects can be confirmed in larger trials with the goal of changing clinical practice and improving child health.

Owing to the high prevalence of gastrointestinal dysfunction in patients, the gut-brain axis is considered to play a vital role in neurodevelopment diseases. Recent pieces of evidence have pointed to the usage of antibiotics at an early developmental stage to be a causative factor in autism due to its ability to induce critical changes in the gut microbiota. The purpose of the study is to determine the neuroprotective effect of capric acid (CA) on autism in antibiotic-induced gut dysbiosis in rodents.

(Mtb) is a leading cause of death, with an escalating global occurrence of drug-resistant infections that are partially attributed to cell wall mycolic acids derived from type II fatty acid biosynthesis (FAS-II). Here, the central acyl carrier protein, AcpM, contributes to the regulation of complex and specific protein-protein interactions (PPIs), though the orchestration of these events remain largely unresolved due to unique features of AcpM. Limitations include complexities in generating modified AcpM in a single state.
