Types of Toxins

1.7K
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.
Environmental pollutants like...

Skin Diseases and Disorders

3.9K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Toxic Reactions: Overview01:26

Toxic Reactions: Overview

981
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,...

The Electron Transport Chain01:30

The Electron Transport Chain

16.8K
The electron transport chain or oxidative phosphorylation is an exothermic process in which free energy released during electron transfer reactions is coupled to ATP synthesis. This process is a significant source of energy in aerobic cells, and therefore inhibitors of the electron transport chain can be detrimental to the cell's metabolic processes.
Inhibitors of the electron transport chain
Rotenone, a widely used pesticide, prevents electron transfer from Fe-S cluster to ubiquinone or Q...

Summary
This summary is machine-generated.

Equine mycotoxicosis, caused by toxins in feed like aflatoxins and fumonisins, presents nonspecific signs such as colic and liver damage. Treatment focuses on removing contaminated feed and supportive care due to rare antidotes.

Area of Science:

  • Equine Health
  • Toxicology
  • Animal Science

Background:

  • Mycotoxins are toxic secondary metabolites produced by fungi that can contaminate animal feed.
  • Equine exposure to mycotoxins is a significant concern, leading to various adverse health effects.
  • Common sources of mycotoxin contamination in equine diets include grains, byproducts, grasses, and hays.

Purpose of the Study:

  • To identify the primary mycotoxins implicated in equine health issues.
  • To describe the common routes of exposure and clinical manifestations of equine mycotoxicosis.
  • To outline current treatment strategies for mycotoxin-induced illnesses in horses.

Main Methods:

  • Review of scientific literature on equine mycotoxicosis.
  • Identification of prevalent mycotoxins affecting horses, including aflatoxins, fumonisins, trichothecenes, and ergovaline.
  • Analysis of clinical signs, diagnostic approaches, and therapeutic interventions.

Main Results:

  • Aflatoxins, fumonisins, trichothecenes, and ergovaline are the principal mycotoxins associated with equine health problems.
  • Clinical signs range from nonspecific symptoms like feed refusal, colic, diarrhea, and liver damage to severe neurological signs (e.g., equine leukoencephalomalacia).
  • Effective antidotes for mycotoxicosis are scarce, necessitating management strategies focused on feed decontamination and supportive care.

Conclusions:

  • Mycotoxin contamination poses a substantial risk to equine health, with diverse clinical presentations.
  • Prompt identification of contaminated feed sources and cessation of exposure are critical for managing mycotoxicosis.
  • Supportive care and dietary management are the cornerstones of treatment in the absence of specific antidotes.
