Protein Complex Assembly02:41

Protein Complex Assembly

16.8K
Proteins can form homomeric complexes with another unit of the same protein or heteromeric complexes with different types.  Most protein complexes self-assemble spontaneously via ordered pathways, while some proteins need assembly factors that guide their proper assembly. Despite the crowded intracellular environment, proteins usually interact with their correct partners and form functional complexes.
Many viruses self-assemble into a fully functional unit using the infected host cell to...

Hybridoma Technology

17.8K
Hybridoma technology is used for the large-scale production of monoclonal antibodies. Monoclonal antibodies bind to only a single antigenic determinant or epitope. Such antibodies are used in research, diagnostics, and disease therapy. The hybridoma technology established in 1975 by Georges Köhler and Cesar Milstein was awarded the Nobel Prize in Medicine in 1984 for revolutionizing research and therapy.

Protein Complexes with Interchangeable Parts01:57

Protein Complexes with Interchangeable Parts

2.9K
Groups of proteins may form a complex where each protein in this complex has a different role in the overall execution of the complex’s function. Often some of the proteins in the complex can be replaced by a closely related variant to give a complex that contains many of the same components yet is functionally distinct.
The SCF ubiquitin ligase is a protein complex of five individual proteins. This complex attaches ubiquitin to other target proteins to mark them for degradation. In order...

Complex Numbers01:29

Complex Numbers

322
The real number system cannot represent the square root of a negative number, which restricts solutions for certain equations, such as quadratics with negative discriminants. To address this, the complex number system was developed, introducing the imaginary unit i, where i = √(-1). This extension allows for the representation of all roots, including those involving negative radicands.A complex number is written in the form x + yi, where x and y are real numbers. Here, x represents the...

Formation of Complex Ions

26.2K
A type of Lewis acid-base chemistry involves the formation of a complex ion (or a coordination complex) comprising a central atom, typically a transition metal cation, surrounded by ions or molecules called ligands. These ligands can be neutral molecules like H2O or NH3, or ions such as CN− or OH−. Often, the ligands act as Lewis bases, donating a pair of electrons to the central atom. These types of Lewis acid-base reactions are examples of a broad subdiscipline called coordination...

  • Pulmonology

Background:

  • Increasing lung cancer screening detects early-stage disease, multifocal tumors, and second primaries.
  • Advances in minimally invasive techniques drive innovation in lung cancer surgery.
  • Anatomic segmentectomy is gaining prominence for early-stage lung cancer treatment.

Purpose of the Study:

  • To describe an innovative operative technique for single basilar segmental resection using ICG-guided VATS.

  • Methylene blue dye localization using SuperDimension electromagnetic navigational bronchoscopy.
  • Three-dimensional (3D) modeling of CT scans for tumor visualization.

Main Results:

  • Successful S10 segment removal via VATS with ICG and methylene blue.
  • Parenchymal-sparing segmentectomy removed 5% of lung volume versus 25% for lobectomy.
  • Preserved lung function allows for future treatment options in multifocal disease.
