Tonicity in Animals00:59

Tonicity in Animals

124.3K
The tonicity of a solution determines if a cell gains or loses water in that solution. The tonicity depends on the permeability of the cell membrane for different solutes and the concentration of nonpenetrating solutes in the solution within and outside of the cell. If a semipermeable membrane hinders the passage of some solutes but allows water to follow its concentration gradient, water moves from the side with low osmolarity (i.e., less solute) to the side with higher osmolarity (i.e.,...

Tonicity in Animals

5.2K
Tonicity describes the amount of solute in a solution. The measure of the tonicity of a solution, or the total amount of solutes dissolved in a specific amount of solution, is called its osmolarity. Three terms—hypotonic, isotonic, and hypertonic—are used to relate the osmolarity of a cell to the osmolarity of the extracellular fluid that contains the cells. In a hypotonic solution, such as tap water, the extracellular fluid has a lower concentration of solutes than the fluid inside...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

9.2K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Animal and Plant Cell Structure

48.3K
Animal and plant cells not only differ in their structure, function, and mode of nutrition but also in how they reproduce, specialize, and organize into complex structures.
Cell Division
Though both plant and animal cells divide by mitosis (for non-gametic cells) and meiosis (for gametic cells), they differ in the specifics of this process. Unlike animal cells, plant cells lack centrosomes — an organelle responsible for organizing the spindle fibers and segregating the chromosomes during...

Molecular Models

43.7K
Physical models representing molecular architectures of chemical compounds play essential roles in understanding chemistry. The use of molecular models makes it easier to visualize the structures and shapes of atoms and molecules.

The Bohr Model02:18

The Bohr Model

80.9K
Following the work of Ernest Rutherford and his colleagues in the early twentieth century, the picture of atoms consisting of tiny dense nuclei surrounded by lighter and even tinier electrons continually moving about the nucleus was well established. This picture was called the planetary model since it pictured the atom as a miniature “solar system” with the electrons orbiting the nucleus like planets orbiting the sun. The simplest atom is hydrogen, consisting of a single proton as the...

Area of Science:

  • Dermatology
  • Toxicology
  • Biotechnology

Background:

  • Current animal models partially replicate human skin, leading to clinical translation challenges.
  • Ethical considerations and the 3Rs principle (Replacement, Reduction, Refinement) drive the need for non-animal alternatives.
  • Human skin's accessibility and the potential for in vitro propagation of cell types facilitate alternative model development.

Purpose of the Study:

  • To review existing non-animal models for dermatological research.
  • To highlight the evolution and potential of these alternative models.
  • To address the need for improved human skin pathophysiology recapitulation.

Main Methods:

  • Review of in vitro reconstructed human skin models.
  • Analysis of in silico computational approaches for pathway modeling.
  • Assessment of bioengineered skin substitutes with increasing complexity.

Main Results:

  • Bioengineered skin substitutes increasingly resemble native skin architecture and biological functions.
  • In silico methods leverage existing human data to model disease pathways without animal testing.
  • A range of non-animal models are available for dermatological applications.

Conclusions:

  • Non-animal models offer promising alternatives to traditional animal testing in dermatology.
  • Technological advancements are enhancing the predictive power of these models for human skin conditions.
  • These models align with ethical research principles and improve the translation of preclinical findings.
