Molecular Shapes

61.9K
Molecules have characteristic shapes that are crucial for their function. The arrangement of various electron groups around the central atom dictates their molecular geometry. Electron pairs in the valence shell of a central atom will adopt an arrangement that minimizes repulsions between the electron pairs by maximizing the distance between them. The valence electrons form either bonding pairs, located primarily between bonded atoms, or lone pairs.
Two regions of electron density in a diatomic...

Conserved Binding Sites

5.2K
Many proteins’ biological role depends on their interactions with their ligands, small molecules that bind to specific locations on the protein known as ligand-binding sites. Ligand-binding sites are often conserved among homologous proteins as these sites are critical for protein function.
Binding sites are often located in large pockets, and if their location on a protein’s surface is unknown, it can be predicted using various approaches. The energetic method computationally...

Area of Science:

  • Medical Imaging
  • Obstetrics and Gynecology
  • Diagnostic Ultrasound

Background:

  • Artifacts are common in 3D sonography during pregnancy.
  • These artifacts can disrupt diagnostic procedures and mimic fetal malformations.

Purpose of the Study:

  • To classify artifacts encountered in 3D sonographic examinations of fetuses.
  • To categorize artifacts based on their visual appearance.

Main Methods:

  • Analysis of 2349 healthy fetal ultrasound examinations over five years.
  • Categorization of observed artifacts into six distinct types based on appearance.

Main Results:

  • Significant artifacts were identified in 119 examinations.
  • The most frequent artifacts included fetal movement (39), acoustic shadowing (25), and volume box amputation (19).

Conclusions:

  • Certain artifacts can be avoided by optimizing the volume box and scanning angle.
  • Proper gain, threshold adjustment, and precise use of the electronic scalpel can minimize other artifacts.
  • Recognizing artifacts is vital to prevent misdiagnosis in 3D ultrasound.
