OBJECTIVES: Although it is commonly recognized that dietary restrictions may improve the clinical course of Menière's disease, their effectiveness has not been definitely demonstrated. The aim of this study was to examine whether caffeine consumption could be involved in Menière's disease. METHODS: Cross-sectional, observational, case-control study, comparing caffeine consumption (intake of coffee, tea, kola-type beverages, energy drinks, and chocolate-containing beverages or foods) between patients with Menière's disease (group A) and patients affected by vertigo with other origins (group B) and/or control subjects (group C)...

Many studies have shown that a maternal low-protein diet increases the susceptibility of offspring to cardiovascular disease in later-life. Moreover, a lower incidence of cardiovascular disease in females than in males is understood to be largely due to the protective effect of high levels of estrogens throughout a woman's reproductive life. However, to our knowledge, the role of estradiol in moderating the later-life susceptibility of offspring of nutrient-deprived mothers to cardiovascular disease is not fully understood...

INTRODUCTION: Accumulating evidence indicates that cognitive decline depends not only upon changes in brain health, but critically, also upon nutritional status. Decline in fluid intelligence, one of the most debilitating aspects of cognitive aging, has been linked to omega-3 polyunsaturated fatty acid (PUFA) status; however, it is not known whether this phenomenon results from specific omega-3 PUFAs acting on particular aspects of brain health. Therefore, this study aims to explore whether particular patterns of omega-3 PUFAs influence fluid intelligence by supporting specific neural structures...

While chronic stress induces dendritic atrophy in the hippocampus and impairs learning and memory, supplementation with n-3 polyunsaturated fatty acids (n-3 PUFA) is known to improve learning and memory of control rats. Whether n-3 PUFA supplementation improves dendritic morphology, synaptic transmission, and memory of chronically stressed rats remains unknown. In this work, we randomly assigned male Sprague-Dawley rats in four experimental groups: two unsupplemented groups, control and stress, and two supplemented groups with n-3 PUFA (DHA and EPA mix), control + n-3 PUFA and stress + n-3 PUFA...

OBJECTIVES: Sleep quality may be directly related with vitamin D serum level. Some studies found that people with lower vitamin D serum level experienced a lower sleep quality. Consequently, this study aimed at determining the effect of vitamin D supplements on sleep score and quality in 20-50 year-old people with sleep disorders. METHODS: This double blind, clinical trial was performed in November 2015-February 2016 on 89 people with sleep disorders based on Petersburg's Sleep Index...

INTRODUCTION: Alzheimer's disease (AD) is a neurodegeneration disorder characterized by progressive impairments of memory, language, reasoning, and other cognitive functions. Evidence suggests that omega-3 fatty acids may act as a possible protection factor in AD. OBJECTIVE: To evaluate the results available in the literature involving omega-3 fatty acids supplementation and its effect on cognitive function in AD patients. METHODS: A systematic review of MEDLINE (from PubMed), Excerpta Medica Database, and Cochrane Library databases was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines...

Glutamate-induced neurotoxicity is related to excessive oxidative stress accumulation and results in the increase of neuronal cell death. In addition, glutamate has been reported to lead to neurodegenerative diseases, including Parkinson's and Alzheimer's diseases.It is well known that Fraxinus rhynchophylla contains a significant level of oleuropein (Ole), which exerts various pharmacological effects. However, the mechanism of neuroprotective effects of Ole is still poorly defined. In this study, we aimed to investigate whether Ole prevents glutamate-induced toxicity in HT-22 hippocampal neuronal cells...

OBJECTIVE: To explore Zn(2+) deficiency-induced neuronal injury in relation to DNA methylation, providing valuable data and basic information for clarifying the mechanism of Zn(2+) deficiency-induced neuronal injury. METHODS: Cultured hippocampal neurons were exposed to the cell membrane-permeant Zn(2+) chelator N,N,N',N'-Tetrakis (2-pyridylmethyl) ethylenediamine (TPEN) (2 μM), and to TPEN (2 μM) plus ZnSO4 (5 μM) for 24 hours. We analyzed intracellular Zn(2+) levels, neuronal viability, and protein/mRNA levels for DNA (cytosine-5) methyltransferase 1 (DNMT1), DNA (cytosine-5-) methyltransferase 3 alpha (DNMT3a), methyl CpG binding protein 2 (MeCP2), Brain-derived neurotrophic factor (BDNF), and growth arrest and DNA-damage-inducible, beta (GADD45b) in the treated neurons...

Wernicke's encephalopathy (WE) is an unexpected common neurological disorder caused by thiamine deficiency often due to alcohol abuse, but WE-not alcohol related is also frequent. A prolonged reduction of food intake can cause WE. This condition can arise in depression disorders, especially in the early stages of these psychiatric syndromes. WE is characterized by the triad of signs: ataxia, ocular dysfunctions and confusional state. However, they rarely appear together and this makes the diagnosis particularly difficult, especially when there is not a history of alcohol abuse...

OBJECTIVES: This fMRI study evaluated the cognitive mechanisms and the cerebral substrates when evaluating the healthiness of food products from nutritional information displayed either with a traffic light (TL) system, a colored nutritional label, or with a guideline daily amount (GDA) system, a numeric label. We postulated that TL label would recruit emotional processes and activation of subjacent cerebral regions (e.g. insula and amygdala). On the contrary, the nutritional information presented in a GDA label, would recruit, due to its numeric format and higher complexity, supplementary cognitive processes and activation of related brain regions (e...

BACKGROUND: Oxidative stress has long been linked to neuronal cell death in many neurodegenerative diseases. Antioxidant conventional supplements are poorly effective in preventing neuronal damage caused by oxidative stress due to their inability to cross the blood brain barrier. Hence the use of molecules extracted from plants and fruits such as phenolics, flavonoids, and terpenoids compounds constitute a new wave of antioxidant therapies to defend against free radicals. OBJECTIVE: In this study we examined the effects of punicalagin, a ellagitannin isolated from the pomegranate juice, on a rat adrenal pheochromocytoma cell line, treated with hydrogen peroxide, evaluating the viability, oxidation potential, mitochondrial function, and eventual apoptosis...

INTRODUCTION: Schizophrenia is a chronic disease that possesses various clinical manifestations. It presents rather heterogeneous characteristics with respect to onset type, symptoms, and the course of the disease. Although the lifetime prevalence is as low as 1%, it can cause serious disability. Thus, it is very important to develop efficient treatment methods. In some studies, it is hypothesized that removing gluten from the diet leads to a significant improvement in disease symptoms...

The study aimed to explore how both sex and dietary restraint impacts brain activation in response to visual food stimuli in young adolescents (12-13 years) under fed and fasted conditions. Food and non-food images were viewed by 15 boys and 14 girls, while functional magnetic resonance images were acquired. The adolescents were either fasted or in a satiated (fed) state following a randomized crossover study design. When satiation state was not considered, girls showed significantly greater brain activity than boys in regions associated with executive function and decision making, working memory, and self-awareness...

Multiple sclerosis (MS) is a multifactorial, inflammatory, and neurodegenerative disease of the central nervous system, where environmental factors interact with genetic susceptibility. The role of diet on MS has not been comprehensively elucidated; therefore, through an extensive search of relevant literature, this review reports the most significant evidence regarding nutrition as a possible co-factor influencing the inflammatory cascade by acting on both its molecular pathways and gut microbiota. Since nutritional status and dietary habits in MS patients have not been extensively reported, the lack of a scientific-based consensus on dietary recommendation in MS could encourage many patients to experiment alternative dietetic regimens, increasing the risk of malnutrition...

OBJECTIVE: The objective of this study was to determine the influence of dietary macronutrient composition on central NPY's orexigenic effect in chicks. METHODS: Day-of-hatch chicks were fed one of three diets (3000 kcal ME/kg) ad libitum from hatch: high carbohydrate (HC), high fat (HF; 30% ME derived from soybean oil), and high protein (HP; 25 vs. 22% CP). In Experiment 1, chicks received intracerebroventricular injections of 0 (vehicle), 0.2, or 2.0 nmol NPY on day 4 and food intake was recorded for 6 hours...

Recent investigations have focused on the potential role of gastrointestinal (GI) abnormalities in the pathogenesis of Parkinson's disease (PD). The 'dual-hit' hypothesis of PD speculates that a putative pathogen enters the brain via two routes: the olfactory system and the GI system. Here, we investigated (1) whether local exposures of the neurotoxin rotenone in the gut or the brain of mice could induce PD-like neurological and GI phenotypes as well as a characteristic neuropathology in accordance with this 'dual-hit hypothesis' and (2) the effects of a diet containing uridine and fish oil providing docosahexaenoic acid (DHA), in both models...
