Effects of Caloric Restriction and Intermittent Fasting and Their Combined Exercise on Cognitive Functioning: A Review.

Purpose Of Review: The impact of dietary habits on cognitive function is increasingly gaining attention. The review is to discuss how caloric restriction (CR) and intermittent fasting (IF) can enhance cognitive function in healthy states through multiple pathways that interact with one another. Secondly, to explore the effects of CR and IF on cognitive function in conditions of neurodegenerative diseases, obesity diabetes and aging, as well as potential synergistic effects in combination with exercise to prevent cognitively related neurodegenerative diseases.

PBAT-modified starch blended film extract induces in vitro toxicity in L-02 cells: induction of oxidative stress, inflammation, and modulation of AMPK pathway.

PBAT-modified starch blended film are thermoplastic biodegradable materials with good properties and a wide range of applications. In this study, L-02 cells were used as an in vitro toxicity evaluation system for risk assessment of PBAT-modified starch films with migration studies obtained in different food simulants. Determination of total migration and organic matter revealed that the results were in accordance with the standard except for the total organic matter under 95% (v/v) ethanol food simulant which exceeded the standard.

Lycium barbarum polysaccharides attenuate nonylphenol and octylphenol-induced oxidative stress and neurotransmitter disorders in PC-12 cells.

Nonylphenol (NP) and octylphenol (OP) are environmental contaminants with potential endocrine disrupting effects. However, there is limited research on the mechanisms and intervention of combined NP and OP exposure-induced neurotoxicity. This study aims to explore the cytotoxicity of combined NP and OP exposure and evaluate the potential of Lycium barbarum polysaccharides (LBP) in mitigating the aforementioned toxicity.

Lycium barbarum polysaccharides attenuate oxidative stress and mitochondrial toxicity induced by mixed plasticizers in HepG2 cells through activation of Nrf2.

Aims: In daily life, it is common for humans to be exposed to multiple phthalate esters (PAEs). However, there is limited research on the mechanisms and intervention of combined PAEs toxicity. This study aims to explore the cytotoxicity of combined PAEs and evaluate the potential of Lycium barbarum polysaccharides (LBP) in mitigating the aforementioned toxicity.

Update on new trends and progress of natural active ingredients in the intervention of Alzheimer's disease, based on understanding of traditional Chinese and Western relevant theories: A review.

Alzheimer's disease (AD) is one of the major neurological disorders causing death in the elderly worldwide. As a neurodegenerative disease that is difficult to prevent and cure, the pathogenesis of AD is complex and there is no effective cure. A variety of natural products derived from plants have been reported to have promising anti-AD activities, including flavonoids, terpenes, phenolic acids and alkaloids, which can effectively relieve the symptoms of AD in a variety of ways.

Nicotinamide mononucleotide (NMN) ameliorated Nonylphenol-induced learning and memory impairment in rats via the central 5-HT system and the NAD/SIRT1/MAO-A pathway.

Nonylphenol (NP) exposure can trigger neurotoxicity and cause learning and memory impairment. Nicotinamide mononucleotide (NMN) has a therapeutic effect on neurodegenerative diseases, but the role of NMN on NP-induced learning and memory impairment is not known. Here, we examined the mitigative effect of NMN on the impaired learning and memory ability of rats exposed to NP.

Structural characterization of pectic polysaccharides from Amaranth caudatus leaves and the promotion effect on hippocampal glucagon-like peptide-1 level.

In this study, decolorized pectic polysaccharides (D-ACLP) with molecular weight (Mw) distribution of 3483- 2,023,656 Da were prepared from Amaranth caudatus leaves. Purified polysaccharides (P-ACLP) with the Mw of 152,955 Da were further isolated from D-ACLP through gel filtration. The structure of P-ACLP was analyzed by 1D and 2D NMR spectra.

The mechanisms of learning and memory impairment caused by nonylphenol: a narrative review based on in vivo and in vitro studies.

Learning and memory play a fundamental role on brain cognitive functions which are crucial for human life. Nonylphenol (NP), a serious environmental pollutant over the world, is proven to be harmful for learning and memory mainly via diet exposure. Currently, besides the administrative restrictions for the use of NP, there are rarely other effective approaches against learning and memory impairment caused by NP.

Learning and memory impairment induced by 1,4-butanediol is regulated by ERK1/2-CREB-BDNF signaling pathways in PC12 cells.

1,4-butanediol (1,4-BD) is a known γ-hydroxybutyric acid (GHB) precursor which affects the nervous system after ingestion, leading to uncontrolled behavioral consequences. In the present study, we investigated whether 1,4-BD induces oxidative stress and inflammation in PC12 cells and evaluated the toxic effects of 1,4-BD associates with learning and memory. CCK-8 results revealed a dose-effect relationship between the cell viability of PC12 cells and 1,4-BD when the duration of action was 2 h or 4 h.

Potential for non-starch polysaccharides in the prevention and remediation of cognitive impairment: A comprehensive review.

Non-starch polysaccharides (NSPs) are food ingredients proven to be beneficial in a large number of health issues. However, there is no literature systematic review about the effects and corresponding mechanisms of NSPs on the prevention and remediation of cognitive impairment. In this review, studies on prevention and remediation of NSPs for cognitive deficit caused by diseases, menopause, ageing, chronic stress and environmental pollutants were summarized and the corresponding mechanisms were established.

A Low-Protein High-Fat Diet Leads to Loss of Body Weight and White Adipose Tissue Weight via Enhancing Energy Expenditure in Mice.

Obesity has become a worldwide health problem over the past three decades. During obesity, metabolic dysfunction of white adipose tissue (WAT) is a key factor increasing the risk of type 2 diabetes. A variety of diet approaches have been proposed for the prevention and treatment of obesity.
