Chemical Equilibria: Redefining Equilibrium Constant01:20

Chemical Equilibria: Redefining Equilibrium Constant

1.3K
The effect of an inert salt on the solubility of a sparingly soluble salt is known as the salt effect. The degree of the salt effect varies with the ionic strength of the solution, which in turn depends on the activity of the species in the solution. The activity is expressed as the product of concentration and the activity coefficient of the species.
To calculate the equilibrium constants of solutions of moderately high ionic strength, one must account for the salt effect. This redefined...

Computed Tomography

Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Positron Emission Tomography

Positron emission tomography (PET) is a medical imaging technique involving radiopharmaceuticals — substances that emit short-lived radiation. Although the first PET scanner was introduced in 1961, it took 15 more years before radiopharmaceuticals were combined with the technique and revolutionized its potential.
One of the main requirements of a PET scan is a positron-emitting radioisotope, which is produced in a cyclotron and then attached to a substance used by the part of the body...

Properties of Enantiomers and Optical Activity

21.9K
It is essential to understand the difference between chiral and achiral interactions and the implications thereof in optical activity and their applications. Just as our feet, which are chiral, interact uniquely with chiral objects, such as a pair of shoes, but identically with achiral socks, enantiomers of a molecule exhibit different properties only when they interact with other chiral media. An example of a significant implication from this facet is the phenomenon known as optical activity,...

Imaging Biological Samples with Optical Microscopy

11.1K
Optical microscopy uses optic principles to provide detailed images of samples. Antonie van Leeuwenhoek designed the first compound optical microscope in the 17th century to visualize blood cells, bacteria, and yeast cells. In 1830, Joseph Jackson Lister created an essentially modern light microscope. The 20th century saw the development of microscopes with enhanced magnification and resolution.
In optical microscopy, the specimen to be viewed is placed on a glass slide and clipped on the stage...

Area of Science:

  • Ophthalmology
  • Neuroscience
  • Medical Imaging

Background:

  • Amblyopia was historically considered a functional visual disorder without identifiable organic causes.
  • Optical Coherence Tomography (OCT) provides new insights into amblyopia's etiopathology by revealing retinal morphologic anomalies.
  • Understanding the structural basis of amblyopia is crucial for diagnosis and treatment.

Purpose of the Study:

  • To systematically analyze macular thickness, optic nerve changes, and choroidal thickness in patients with amblyopia.
  • To synthesize findings from existing literature on OCT-based evaluations of amblyopia.
  • To identify common structural alterations associated with amblyopia.

Main Methods:

  • A comprehensive literature review of 30 clinical trials published between 2006 and 2016.
  • Studies were identified through the PubMed database.
  • Analysis focused on OCT findings related to macular, optic nerve, and choroidal structures in amblyopic eyes.

Main Results:

  • The majority of studies (19) investigated macular and optic nerve changes, while others focused on choroidal (7) and retinal changes (6).
  • Variability in results was observed across studies.
  • Macular and choroidal involvement appeared more frequently suggested than optic nerve involvement in amblyopia.

Conclusions:

  • OCT demonstrates morphologic anomalies in the retina of amblyopic eyes.
  • Macular and choroidal alterations are more consistently implicated in amblyopia than optic nerve changes.
  • Further research is needed to clarify the complex structural changes in amblyopia.
