Gastrointestinal disturbances, nutritional deficiencies, and food intolerances are frequently observed in children with neurodevelopmental disorders (NDD). To reveal possible association of celiac disease risk variants (HLA-DQ), lactose intolerance associated variant (LCT-13910C>T) as well as variant associated with vitamin D function (VDR FokI) with NDD, polymerase chain reaction-based methodology was used. Additionally, intestinal peptide permeability was estimated in NDD patients and healthy children by measuring the level of peptides in urine using high-performance liquid chromatography...

BACKGROUND: Differences in the composition of control diets may confound outcomes in studies investigating dietary effects. OBJECTIVE: We compared the effects of two control diets commonly used in mice studies, chow (SD) and a purified low-fat diet (LFD), in relation to a chronic high-fat diet (HFD). We hypothesized that SD and LFD will have similar effects on phenotypic, metabolic, and behavioral outcomes. METHODS: Fifty-four 5-week-old male C57BL/6J mice were randomly assigned to one of the three dietary interventions (SD, LFD, or HFD) for 18 weeks...

BACKGROUND: At present, the impact of macronutrient composition and nutrient intake on sustained attention in adults is unclear, although some prior work suggests that nutritive interventions that engender slow, steady glucose availability support sustained attention after consumption. A separate line of evidence suggests that nutrient consumption may alter electroencephalographic markers of neurophysiological activity, including neural oscillations in the alpha-band (8-14 Hz), which are known to be richly interconnected with the allocation of attention...

There is a significant body of research undertaken in order to elucidate the mechanisms underlying the pathology of Alzheimer's disease (AD), as well as to discover early detection biomarkers and potential therapeutic strategies. One such proposed biomarker is the calcium binding protein S100β, which, depending on its local concentration, is known to exhibit both neurotrophic and neuroinflammatory properties in the central nervous system. At present, relatively little is known regarding the effect of chronic S100β disruption in AD...

BACKGROUND: Overnutrition due to a high-fat diet (HFD) can increase the vulnerability of the metabolic system to maladjustments. Estradiol has an inhibitory role on food intake and this hormone has demonstrated to be a crucial organizer during brain development. OBJECTIVE: Our aim was to determine whether increased levels of estradiol in the early postnatal period modulate the alterations in metabolism and brain metabolic circuits produced by overnutrition. METHODS: Twenty-four male and 24 female Wistar rats were submitted to a HFD (34...

Fatty acid-induced hypothalamic inflammation (HI) is a potential cause of the obesity epidemic. It is unclear whether saturated or n-6 polyunsaturated fat is the primary driver of these effects. Premenopausal women are protected, in part, from obesity and associated comorbidities by circulating 17β-estradiol (E2). It is unknown how HI interacts with E2, because most studies of HI do not examine females despite the involvement of E2 in hypothalamic energy homeostasis. Our objective is to determine the effects of high-fat diets with varying levels of linoleic acid (LA) and saturated fat on the energy and glucose homeostasis in female mice with and without E2...

Polyunsaturated fatty acids (PUFAs) are lipid derivatives of omega-3 (docosahexaenoic acid, DHA, and eicosapentaenoic acid, EPA) or of omega-6 (arachidonic acid, ARA) synthesized from membrane phospholipids and used as a precursor for endocannabinoids (ECs). They mediate significant effects in the fine-tune adjustment of body homeostasis. Phyto- and synthetic cannabinoids also rule the daily life of billions worldwide, as they are involved in obesity, depression and drug addiction. Consequently, there is growing interest to reveal novel active compounds in this field...

The formation of β amyloid plaques is one of the pathological hallmarks of Alzheimer's disease (AD). The process of accumulation of extracellular deposits of amyloid plaques occurs by the abnormal proteolysis of amyloid precursor protein, resulting in the formation of β amyloid peptides which further aggregates and results in the formation of oligomers, protofibrils, fibrils, and plaques. The complexity in understanding the aggregation process has provided avenues for identifying potential targets against amyloid toxicity in the treatment of AD...

BACKGROUND: There is evidence that obesity leads to cognitive impairments via several markers of oxidative stress including glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase and malondialdehyde (MDA) in the hippocampus. Increased inflammatory markers in the brain have obesity triggering effects. In the current study we aimed to investigate the effects of vitamin D on cognitive function, nuclear factor (NF)-κB, tumor necrosis factor (TNF)-α concentration and markers of oxidative stress in the hippocampus of high-fat diet-induced obese rats...

BACKGROUND: Obesity and Type 2 Diabetes (T2D) are chronic nutrient-related disorders that occur together and pose a grave burden to society. They are among the most common causes of ageing and death. Obesity and T2D per se accelerate ageing albeit the underlying mechanisms are unclear yet. Also, it is not clear whether or not superimposing T2D on obesity accelerates ageing. Present study validated the hypothesis, 'super-imposing T2D on obesity accelerates ageing' in WNIN/Gr-Ob, the impaired glucose tolerant, obese rat as the model and evaluated probable underlying mechanisms...

Many aspects of human development and disease are influenced by the interaction between genetic and environmental factors. Understanding how our genes respond to the environment is central to managing health and disease, and is one of the major contemporary challenges in human genetics. Various epigenetic processes affect chromosome structure and accessibility of deoxyribonucleic acid (DNA) to the enzymatic machinery that leads to expression of genes. One important epigenetic mechanism that appears to underlie the interaction between environmental factors, including diet, and our genome, is chemical modification of the DNA...

BACKGROUND: Polyunsaturated fatty acids (PUFAs) play an important role in the pathophysiology of major depressive disorder (MDD), related, in part, to their role in inflammatory systems. The enzymes δ-5 and δ-6 desaturase are the rate-limiting steps in the metabolism of PUFAs and are encoded in the genes fatty acid desaturase (FADS) 1 and 2, respectively. Single nucleotide polymorphisms (SNPs) and haplotypes within the FADS gene cluster have been shown to influence PUFA composition...

OBJECTIVE: Macular pigment optical density (MPOD) - a non-invasive indicator of retinal xanthophylls and correlate of brain lutein - has been associated with superior cognitive function among adult populations. Given that lutein accumulation in the brain occurs in early life, it is possible that the cognitive implications of greater MPOD may be evident in childhood. METHODS: Participants aged 8-9 years (n = 56) completed MPOD measurements via heterochromatic flicker photometry...
