The pteropod mollusk, , is a useful model system for understanding the neural basis of behavior. Of particular interest are the unique swimming behavior and neural circuitry that underlies this swimming behavior. The swimming system of has been studied by two primary groups-one in Russia and one in the United States of America-for more than four decades. The neural circuitry, the cellular properties, and ion channels that create and change the swimming locomotor rhythm of -particularly mechanisms that contribute to swimming acceleration-are presented in this review.

Background: Girls' physical activity and healthful eating behaviors decline throughout adolescence. These trajectories may be linked to the underdevelopment of exercise and healthful eater identities. Youth programs might consider prioritizing identity development as an innovative health promotion strategy, especially during the formative preadolescent life stage.

Phenanthrene is considered a priority polycyclic aromatic hydrocarbon due to its ubiquitous presence in aquatic and terrestrial environments and its toxic potential. Tadpoles are sensitive ecotoxicological models that provide important information regarding effects of contaminants in amphibian species. The goal of the present study was to generate information regarding the acute and chronic toxicity of phenanthrene to the neotropical tree frog Dendropsophus branneri early life stages.

Background: During their nighttime shoaling, the flashlight fish Anomalops katoptron produce fascinating, bioluminescent blink patterns, which have been related to the localization of food, determination of nearest neighbor distance, and initiation of the shoal's movement direction. Information transfer e.g.

Diisopentyl phthalate (DiPP) is present in many consumer goods, but can be absorbed into the human body, and can disrupt the endocrine system affecting reproductive health and fetal development. Studies revealed that biological samples of pregnant women in Brazil contained DiPP, raising even more the concerns about its usage. This study investigated how DiPP concentrations (12.

Dimethyl phthalate (DMP) has been extensively utilized as a plasticizer on a global scale for many years. Its presence in the environment and its harmful effects on living organisms have raised concerns. This study aimed to examine its potential developmental neurotoxicity by utilizing zebrafish as a model.
