Summary
Toxic peripheral neuropathies, caused by xenobiotics, damage the peripheral nervous system. Understanding neurotoxicant mechanisms aids in developing detection methods and treatments for these acquired polyneuropathies.
Area of Science:
- Neuroscience
- Toxicology
- Biochemistry
Background:
- Toxic peripheral neuropathies are acquired polyneuropathies resulting from xenobiotic exposure.
- Understanding their mechanisms is crucial for developing diagnostic and therapeutic strategies.
Purpose of the Study:
- To provide an overview of toxic peripheral neuropathies.
- To elucidate the targeting of the peripheral nervous system by neurotoxicants.
- To discuss degenerative pathways involved in these conditions.
Main Methods:
- Review of experimental data and hypotheses on neurotoxicant mechanisms.
- Focus on agents causing neuronopathies, axonopathies, or myelinopathies.
- Discussion of molecular and cellular damage mechanisms.
Main Results:
- Xenobiotics induce peripheral nerve damage through various mechanisms.
- These include covalent/noncovalent modifications, energy compromise, oxidative injury, and ionic gradient disruption.
- Inter-component signaling and programmed cell death pathways are implicated.
Conclusions:
- Elucidating neurotoxicant mechanisms is key to developing predictive models and interventions.
- Targeting glia-neuron-axon signaling and programmed degeneration offers therapeutic avenues.
- This review synthesizes current knowledge on toxic peripheral neuropathies.

Subviral Agents
546
Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Toxic Reactions: Overview
1.8K
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

Air-entraining Agents
262
Air-entraining agents improve the durability and workability of concrete in climates with frequent freezing and thawing. These agents prevent cracks by introducing small air bubbles into the mix, creating spaces accommodating water expansion when temperatures drop. The air-entraining agents lower the surface tension of water, forming stable, small air bubbles. This method is more effective than having accidental large voids, as the intentional, smaller, and evenly distributed air voids improve...

Reaction Mechanisms
30.6K
Chemical reactions often occur in a stepwise fashion, involving two or more distinct reactions taking place in a sequence. A balanced equation indicates the reacting species and the product species, but it reveals no details about how the reaction occurs at the molecular level. The reaction mechanism (or reaction path) provides details regarding the precise, step-by-step process by which a reaction occurs.
For instance, the decomposition of ozone appears to follow a mechanism with two steps:

Masking and Demasking Agents
3.5K
EDTA titrations may necessitate masking and demasking agents to temporarily protect a particular metal ion in a mixture from the EDTA reaction. These agents facilitate the sequential analysis of the metal ions by forming stable complexes with some—but not all—metal ions during certain steps.
There are many masking agents, such as cyanide, fluoride, triethanolamine, thiourea, and 2,3-bis(sulfanyl)propan-1-ol (formerly 2,3-dimercapto-1-propanol), with the masking agent chosen based on...

Mechanical Protein Functions
5.5K
Proteins perform many mechanical functions in a cell. These proteins can be classified into two general categories- proteins that generate mechanical forces and proteins that are subjected to mechanical forces. Proteins providing mechanical support to the structure of the cell, such as keratin, are subjected to mechanical force, whereas proteins involved in cell movement and transport of molecules across cell membranes, such as an ion pump, are examples of generating mechanical force.
