Modes of action of toxic agents.
The principal modes of action of toxic agents are discussed in relation to the type of chemical bond formed between the poison and the target constituent of tissues. Alteration of enzyme activity, interference with the binding of poisonous chemicals to proteins, intercalation with nucleic acids, disturbances in electrolyte balance and the disorganization of cellular water and membrane lipids ar...
متن کاملThe Toxic Action of Copper on Nitella
1. Using the loss of turgidity of the cells as a criterion it is found that the toxicity curve of copper chloride with Nitella is sigmoid. An empirical equation can be constructed which will approximately fit the curve. 2. When the concentration of the copper chloride is varied the toxic effect varies as a constant, fractional, power of the concentration. This relation holds when the concentrat...
متن کاملMechanism of action of toxic halogenated aromatics.
2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) and related halogenated aromatic hydrocarbons are a highly toxic class of environmental contaminants, as evidenced by numerous cases of accidental poisonings of human and animal populations and their extreme toxic potency in laboratory animals. The proposed model for the mechanism of action of TCDD and related compounds is analogous to that of the ster...
متن کاملAction mirroring and action understanding in children
The past decade has experienced an increasing interest in action underestanding and children’s mirroring of others’ behavior. Behavioral investigations have focused on the development and significance of mimicry, goal prediction and imitation. Others have focused on the neural basis of action mirroring, identifying particular electrophysiological markers or related brain regions. A vivid debate...
متن کاملTemperature and toxic Tau in Alzheimer's disease: new insights.
Alzheimer's disease (AD), the most common dementia in the elderly, is characterized by cognitive impairment and severe autonomic symptoms such as disturbance in core body temperature (Tc), which may be predictors or early events in AD onset. Inclusions of phosphorylated Tau (p-Tau) are a hallmark of AD and other neurodegenerative disorders called "Tauopathies." Animal and human studies show tha...
