OBJECTIVE: Ginger and its compound, 6-shogaol, have been known for improving gastrointestinal (GI) function and reducing inflammatory responses in GI tract. Recently, the treatment of GI dysfunction has been recognized as an important part of the management of neurodegenerative diseases, especially for Parkinson's disease (PD). In this study, we investigated whether ginger and 6-shogaol attenuate disruptions induced by 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) on the intestinal barrier and the enteric dopaminergic neurons...

OBJECTIVES: The calcium-sensing receptor (CaSR), the major sensor of extracellular Ca2+ , is expressed in various tissues, including the gastrointestinal tract. Although the essential ligand of CaSR is calcium, its activity can be regulated by aromatic L-amino acids. The expression of CaSR on enteroendocrine cells suggests that CaSR functions as a physiological amino acid sensor for gut hormone release. Here, we investigated the effects of L-tryptophan (L-Trp) on rat glucagon-like peptide-1 (GLP-1), peptide YY (PYY), and insulin secretion, and the role of CaSR in this mechanism in vivo...

Alzheimer disease (AD) is a progressive neurodegenerative brain disorder that causes significant disruption in normal brain functioning, representing the most common cause of dementia in the elderly. The main hallmark of AD is the presence of amyloid plaques in the brain formed by the deposition of insoluble amyloid protein (Aβ) outside of neurons. Despite intensive investigation of the mechanisms of AD pathogenesis during the past three decades, little has been achieved in terms of effective treatments or ways to prevent the disease...

OBJECTIVES: Hypercholesterolaemia has been implicated in the pathogenesis of neurodegenerative diseases. In this work, we tested whether cholesterol-mediated neurodegeneration induced either by cholesterol-rich diet or genetic mutation may share a common mechanism involving increased oxidative stress and mitochondria oxidant status. Additionally, we analysed whether upon cholesterol-rich diet, different brain regions (prefrontal cortex, cortex, hippocampus, and cerebellum) show distinct vulnerability to an oxidative stress response...

The present study investigated the effect of high-temperature-processed green tea extract (HTP_GTE) and its bioactive components on the reduction of reactive oxygen species (ROS) and amyloid-beta (Aβ) protein in human microvascular endothelial cells. Compared to Aβ1-42 -only treatment, pretreatment of HTP_GTE was revealed to effectively inhibit ROS generation (P<0.05). HTP_GTE and catechins not only inhibit Aβ1-42 fibril formation but also destabilize preformed Aβ1-42 fibrils. The presence of HTP_GTE, Aβ1-42 fibril formation was significantly inhibited in a dose-dependent manner at 12...

OBJECTIVES: Recent work suggests potential postprandial benefits for cognition and on-task behavior in children, depending on the macronutrients consumed, as well as individual differences such as sex and glucoregulation. We examined the effects of 1% milk versus apple juice on cognition and on-task behavior among healthy school-age children, predicting that milk would promote better performance and a greater presence of on-task behavior compared to juice. We also examined how sex and glucoregulation influenced cognition and behavior following each beverage...

BACKGROUND: Wernicke encephalopathy (WE) predominantly occurs in alcoholic patients. Few case reports have described this diagnosis as a result of dieting. The diagnosis is often missed or delayed resulting in permanent and severe neurologic sequelae and even death. The typical neurological signs may be absent or missed during the early stages of thiamine deficiency. Case report; A 23-year-old female presented to the hospital with confusion, bilateral lateral rectus palsy, and ataxia...

Background Dietary intake of long-chain omega 3 (n-3) polyunsaturated fatty acids (LCPUFA) represents a putative modifiable risk factor for depression, and a high ratio of omega 6 (n-6) to n-3 LCPUFA is frequently observed in patients with major depressive disorder. Recent reports suggest that the availability of fish and seafood may be associated with lower depression rates. The aim of this study was to investigate associations of fish consumption and LCPUFA levels with depressive symptoms. Methods Participants for this cross-sectional study (n=206) were recruited at a community screening programme in two Torres Strait Islander communities (Mer and Waiben)...

Alzheimer's is an age-related disease with a hallmark of progressive loss of memory formation followed by a damage in the brain function due to the neural degeneration and extracellular beta-amyloid (Aβ) plaques accumulation. This study examines the protective effects of vitamin K2 on toxicity induced by (Aβ) (1-42) and H2 O2 in PC12 cells as an appropriate model of Alzheimer's cell damage. PC12 cells pretreated with vitamin K2 (5-200 μM) for 4, 24 and 48 h, and exposed to either Aβ (25 µM) for 48 h or H2 O2 (150 µM) for 24 h...

Epigallocatechin gallate is the most abundant composition of the tea catechins and is thought to be responsible for the majority of biological activity of green tea extracts such as antioxidant, anti-inflammatory, and antiapoptotic effects. Meanwhile, EGCG has been shown to be some of the neuroprotective effects against neural injuries and neurodegenerative diseases. This paper summarizes current knowledge on neuroprotective effects of EGCG and their molecular mechanisms responsible for the neuroprotection in various models of neurodegenerative and neural injury...

OBJECTIVES: A strong rise of the fructose content in the human diet occurred in the last decade, as corn syrup is widely used as a sweetener for beverages and processed food. Since young people make a widespread consumption of added sugars, we evaluated the effects of a two weeks fructose-rich diet on brain redox homeostasis, autophagy and synaptic plasticity in the cortex of young and adults rats, in order to highlight the early risks to which brain is exposed. METHODS AND RESULTS: Short-term fructose feeding was associated with an imbalance of redox homeostasis, as lower amount of Nuclear factor (erythroid derived 2)-like 2, lower activity of Glucose 6-phosphate dehydrogenase and Glutathione reductase, together with lower Glutathione/Oxidized Glutathione ratio, were found in fructose-fed young and adult rats...

A high-fat diet induces hypothalamic inflammation in rodents which, in turn, contributes to the development of obesity by eliciting both insulin and leptin resistance. However, the mechanism by which long-chain saturated fatty acids trigger inflammation is still contentious. To elucidate this mechanism, the effect of fatty acids on the expression of the pro-inflammatory cytokines IL-6 and TNFα was investigated in the mHypoE-N42 hypothalamic cell line (N42). N42 cells were treated with lauric acid (LA) and palmitic acid (PA)...
