Phase Contrast and Differential Interference Contrast Microscopy01:26

Phase Contrast and Differential Interference Contrast Microscopy

14.4K
Phase-Contrast Microscopes
In-phase-contrast microscopes, interference between light directly passing through a cell and light refracted by cellular components is used to create high-contrast, high-resolution images without staining. It is the oldest and simplest type of microscope that creates an image by altering the wavelengths of light rays passing through the specimen. Altered wavelength paths are created using an annular stop in the condenser. The annular stop produces a hollow cone of...

Toxicity Testing in Animals01:23

Toxicity Testing in Animals

1
Toxicity tests in animals are grounded on two main assumptions: first, the effects observed in laboratory animals can be extrapolated to humans, especially when adjusted for body surface area; second, high-dose exposure in animals is essential to identify potential human hazards from lower doses. This is based on the quantal dose-response concept, which faces the challenge of extrapolating results from relatively few test animals to much larger human populations. For example, a 0.01% incidence...

Subviral Agents01:29

Subviral Agents

589
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: Overview01:26

Toxic Reactions: Overview

2.2K
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,...

Drug Toxicity: Overview01:00

Drug Toxicity: Overview

2
Drug toxicity quantifies the harm a compound causes to an organism, varying by dose and potentially impacting whole systems or specific organs like the liver. Toxic reactions may arise from venomous insect or spider bites, with effects ranging from mild symptoms to severe outcomes such as brain damage or death. Common forms of acute poisoning include ethanol intoxication and overdose of pain or fever medications, with substances like GHB and heroin being particularly lethal at doses close to...

Bioactivation and Tissue Toxicity01:25

Bioactivation and Tissue Toxicity

1
Bioactivation is a metabolic process that transforms less reactive substances into highly reactive metabolites, initiating tissue toxicity. This transformation can lead to various toxic effects, including carcinogenesis and teratogenesis. Reactive metabolites are classified into two main types: electrophiles and free radicals.Electrophiles are electron-deficient species and are produced primarily by the enzyme cytochrome P-450 during the metabolism of compounds containing carbon, nitrogen, or...

Area of Science:

  • Radiology
  • Toxicology
  • Pharmacology

Background:

  • Gadolinium-based contrast agents (GBCAs) are linked to nephrogenic systemic fibrosis in patients with renal dysfunction.
  • Recent findings suggest gadolinium brain accumulation even in individuals with normal kidney function.
  • Clinical implications of gadolinium deposition in human tissues, especially the brain, require further investigation.

Purpose of the Study:

  • To discuss the pharmacokinetics and pharmacodynamics of GBCAs.
  • To focus on gadolinium's impact on the brain.
  • To explore potential GBCA-related toxicity in fetal/neonatal and adult/aged populations.

Main Methods:

  • Literature review on GBCA toxicity and pharmacokinetics.
  • Analysis of studies on gadolinium deposition in brain tissue.
  • Discussion of physiological changes influencing GBCA distribution and excretion.

Main Results:

  • GBCA toxicity is associated with molecular stability and pharmacokinetic properties.
  • Physiological changes throughout life affect GBCA distribution, deposition, and toxicity.
  • Specific focus on potential GBCA toxicity during fetal/neonatal and adult/aged periods.

Conclusions:

  • Further research is needed to understand the clinical significance of gadolinium accumulation.
  • GBCA toxicity mechanisms vary based on molecular stability and individual physiology.
  • Life stages significantly influence the risk and nature of GBCA-related toxicity, particularly in the brain.
