Types of Toxins01:36

Types of Toxins

4.1K
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...

Bacterial Toxins01:12

Bacterial Toxins

97
Bacterial toxins are sophisticated virulence factors that enable pathogenic bacteria to interact with, invade, and damage host tissues. These toxins fall broadly into two types: protein exotoxins, which are secreted into the environment and target specific host receptors, and lipopolysaccharide endotoxins, which are structural components of the bacterial outer membrane released primarily during bacterial lysis or membrane shedding. Exotoxins generally act more selectively, binding to cell...

Anthelminthic Agents01:15

Anthelminthic Agents

90
Anthelmintic drugs differ significantly from antiparasitic therapies targeting protozoa, primarily due to differences in parasite biology. Whereas most protozoal treatments act on proliferating cells, anthelmintics are typically directed against mature, nonproliferative helminths. The therapeutic approach considers the helminth's reliance on neuromuscular coordination, glucose metabolism, and microtubular integrity for survival, reproduction, and localization within the host. Most anthelmintics...

Local Anesthetics: Differential Sensitivity of Nerve Fibers01:24

Local Anesthetics: Differential Sensitivity of Nerve Fibers

1.7K
Local anesthetics (LAs) block the sodium channels of nerve trunks, sensory nerve endings, and neuromuscular junctions. Although LAs can block all kinds of nerves, the sensitivity of nerve fibers differs according to nerve types and structures. LAs are known to block myelinated fibers faster than unmyelinated ones. Also, they block pain or sensory neurons at low concentrations without affecting the motor neurons involved in muscle contractions. This helps relieve labor pain without affecting the...

Prevention of Further Absorption of Poison01:14

Prevention of Further Absorption of Poison

1.4K
In cases of acute poisoning, the primary objective is to prevent further absorption of the toxic substance into the body. Immediate interventions using various decontamination techniques targeting the gastrointestinal (GI) tract can achieve this. Decontamination is crucial to prevent poison from entering the systemic circulation, which involves washing affected areas with water and mild soap and removing contaminated clothing. Once external decontamination is done, attention must be turned to...

Area of Science:

  • Biochemistry
  • Molecular Biology
  • Evolutionary Biology

Background:

  • Snake venom evolved as a chemical prey capture mechanism, driving the radiation of advanced snakes (Caenophidia).
  • Small venom proteins, often rich in disulfide bonds, form stable scaffolds presenting functional residues.
  • New toxins arise from over-expression of body proteins, followed by gene duplication and neofunctionalization.

Purpose of the Study:

  • To review cysteine-rich small proteins and peptides in snake venoms.
  • To highlight their 3D structures, biological functions, and therapeutic potential.

Main Methods:

  • Literature review focusing on cysteine-rich venom proteins.
  • Analysis of protein structures and functions.
  • Exploration of therapeutic and research applications.

Main Results:

  • Identification of privileged cysteine-rich scaffolds in venom.
  • Examples include natriuretic peptides and phospholipase enzymes.
  • These toxins show potential as therapeutic agents and research tools.
