Data from epidemiological and experimental studies have shown that diet and eating patterns have a major role in the pathogenesis of many age-associated diseases. Since 1935, calorie restriction (CR) has been identified as one of the most effective nongenetic dietary interventions that can increase lifespan. It involves reducing calorie intake by about 20%–40% below ad libitum, without malnutrition. Restricting food intake has been observed to increase lifespan and prevent many age-associated diseases in rats, mice, and many other species. Understanding the metabolic, molecular, and cellular mechanisms involved in the anti-aging effects of CR can help us to find dietary interventions that can mimic its effects. Recently, different studies have shown that intermittent fasting, protein restriction, and an epigenetic diet can have similar effects to those of CR. These approaches were selected because it has been indicated that they act through a similar molecular pathway and also, are safe and effective in delaying or preventing diseases. In this review, we focus on the mechanistic pathway involved in CR. Then, we review the mimicking interventions through the mechanistic approach. For this purpose, we reviewed both animal and human articles, mainly available through the PubMed online database. We then selected the most relevant full texts which are summarized in this article.

Resilience has received increased attention among both practitioners and scholars in recent years. Child resilience has received notable attention in disaster risk reduction (DRR) during the creation of the Sendai Framework 2015–2030 to improve child protection in the event of disasters. As resilience is a subjective concept with a variety of definitions, this study evaluates its different factors and determinates in the existing research to clarify the path for the near future and objective research. A systematic literature review was conducted by searching and selecting the peer-reviewed papers published in four main international electronic databases including PubMed, SCOPUS, WEB OF SCIENCE, and PsycINFO to answer the research question: “What are the criteria, factors or indicators for child resilience in the context of a natural disaster?” The process was based on PRISMA guidelines. In total, 28 papers out of 1838 were selected and evaluated using thematic analysis. The results are shown in two separate tables: one descriptive and the other analytical. Two main themes and five subthemes for criteria for child resilience in a disaster have been found. The factors found cover the following areas: mental health, spiritual health, physical, social behavior, and ecological, and as well as environmental. The majority of the included studies mentioned the scattered criteria about children resilience without any organized category. Although this concept is multifactorial, additional research is needed to develop this study and also observe other kinds of disasters such as human-made disasters.
