High-fat diets, characterised by their high lipid content, have been associated with structural and functional alterations in the hippocampus of rodents, including a reduction in the expression of brain-derived neurotrophic factor (BDNF), which negatively impacts learning and memory. Evidence suggests that these impairments may be attenuated by regular physical exercise. This review aimed to gather relevant scientific evidence available on the effects of the association between high-fat diets and physical exercise on BDNF expression levels in the hippocampus of rats. The studies analysed highlight a neuroprotective effect of exercise, capable of positively modulating BDNF levels and, consequently, improving the cognitive functions of these animals.

A erosão costeira ocorre em várias partes do mundo. Ela, por vezes, destrói equipamentos e casas próximas da linha de costa causando prejuízos econômicos. No Estado do Ceará existem trechos que estão retrogradando, exemplo clássico é da área próxima do Porto do Mucuripe (Fortaleza). Diante do exposto, o objetivo deste estudo foi analisar a evolução da linha de costa de todo o Estado do Ceará, dentro da escala temporal de 1984 a 2018. Para alcançar esse objetivo foram realizados o processamento digital de imagens de satélite, confecção de mapas de variação da linha de costa e quantificação das áreas de progradação e retrogradação. Em termos matemáticos, na zona costeira do Ceará houve equilíbrio dinâmico entre os processos de acreção e erosão, contudo, existem alguns hotspots de erosão nos diferentes setores do litoral. Há a necessidade de monitoramento contínuo da zona costeira em diferentes escalas espaciais e temporais para melhor compreensão do comportamento costeiro, bem como políticas que inibam a ocupação deletéria a essa região. Shoreline variation in Ceará coastal zone (1984-2018) A B S T R A C TCoastal erosion occurs in several parts of the world. Sometimes, it destroys structures close to the shoreline causing economic damage. In the state of Ceará, Brazil, there are stretches with retrogradation. A classic example is from the area near the Mucuripe harbor (Fortaleza). From this context, the objective of this paper was to analyze the evolution of the State of Ceará shoreline between 1984 and 2018. To achieve this objective, the digital processing of satellite images was performed, developing maps of shoreline variation and quantification of progradation and retrogradation areas. In mathematical terms, at the coastal zone of Ceará there was a dynamic balance between the processes of accretion and erosion. However, there are some erosion hotspots in different sectors of the state shoreline. There is a need for continuous monitoring of the coastal zone in different spatial and temporal scales to better understand coastal behavior, as well as policies that inhibit the deleterious occupation of this region.Keywords: Coastal zone; Monitoring; Coastal Erosion.
