Congenital Chagas disease is caused by the protozoan parasite Trypanosoma cruzi that must cross the placental barrier during transmission. The trophoblast constitutes the first tissue in contact with the maternal-blood ...
An Inescapable Cat Odor Exposure Protocol for Studying Innate and Contextual Threat Conditioning in Rats
(2021)
Animals respond to threatening situations by exhibiting a number of defensive behaviors, including avoidance, freezing, and risk assessment. An animal model with an ethological approach offers a deeper insight into the ...
Biochemical aspects of cellular antioxidant systems
(1996)
Aerobic life is characterized by a steady generation of reactive oxygen species balanced by a similar rate of their consumption by antioxidants. To maintain homeostasis, there is a requirement for the continuous regeneration ...
Does a Defensive Pseudoautotomy Mechanism Exist in the Subfamily Xenodontinae? A Study of the Genus Echinanthera
(Soc Brasileira Herpetologia, 2020-12-01)
Pseudoautotomy is presumably a derived character within Lepidosauria and occurs in taxa that have lost the ability to perform autotomy. In general, species capable of employing pseudoautotomy as a defensive strategy against ...
Instance-based defense against adversarial attacks in Deep Reinforcement Learning
Deep Reinforcement Learning systems are now a hot topic in Machine Learning for their effectiveness in many complex tasks, but their application in safety-critical domains (e.g., robot control or self-autonomous driving) ...
Resource-defense polygyny and self-limitation of population density in free-ranging guanacos
(Oxford Univ Press Inc, 2016-01)
Although ecologists and managers have been increasingly preoccupied with the crowding consequences of overabundant herbivores,the potential role of territorial behavior as a self-regulatory agent has seldom been considered. ...
