The Anchoring-and-Adjustment Heuristic01:25

The Anchoring-and-Adjustment Heuristic

7.7K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Lipids as Anchors01:32

Lipids as Anchors

7.2K
In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.
The carboxy-terminal of most of the prenylated proteins, such as Ras proteins, contains...

Anchoring Junctions01:03

Anchoring Junctions

4.9K
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

GPI Anchoring of Proteins in the ER Membrane01:29

GPI Anchoring of Proteins in the ER Membrane

5.4K
GPI-anchoring is a post-translational, reversible protein modification that is ubiquitous in eukaryotes. Such proteins are primarily present on the exoplasmic leaflet of the plasma membrane.
GPI-anchor structure
A sequence of 11 enzymatic reactions results in the synthesis of the complete GPI anchor consisting of a hydrophobic and a hydrophilic portion. The hydrophobic portion comprises phosphatidylinositol, while the hydrophilic part comprises polar groups like phosphoethanolamine,...

Sutures of the Skull01:22

Sutures of the Skull

10.3K
The human skull is composed of several bones that come together to protect the brain and support the structures of the face. The junctions where these bones meet are called sutures.
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...

Tail-anchoring of Proteins in the ER Membrane01:45

Tail-anchoring of Proteins in the ER Membrane

3.7K
Tail-anchored, or TA, proteins are estimated to make up to 3-5% of membrane proteins found in the eukaryotic cell. Such proteins have a single transmembrane domain located approximately 30 amino acid residues upstream from the C-terminal end. As a result, the signal recognition particle (SRP) cannot guide a TA protein to the ER membrane for cotranslational insertion. Hence, they are integrated into the ER membrane post-translationally using their C-terminal end as the anchor. TA proteins...

Area of Science:

  • Orthopedic surgery
  • Sports medicine
  • Biomechanical engineering

Background:

  • Acromioclavicular (AC) joint dislocation is a frequent injury in active individuals.
  • Current surgical treatments for high-grade AC joint dislocations lack a standardized approach for restoring normal joint kinematics.
  • Existing coracoclavicular (CC) fixation methods, like cortical button fixation, show promise but face challenges with horizontal instability and subsidence.

Purpose of the Study:

  • To introduce and evaluate a novel arthroscopic coracoclavicular (CC) fixation technique for acute, high-grade AC joint dislocations.
  • To overcome the limitations of current fixation methods, specifically addressing horizontal instability and subsidence.
  • To achieve ideal horizontal and vertical stability for restoring native AC joint kinematics.

Main Methods:

  • Development of a unique CC fixation technique utilizing multiple small tunnels and all-suture anchors.
  • Application of an arthroscopic approach for the novel fixation technique.
  • Designed to avoid the large bone tunnels associated with cortical button fixation.

Main Results:

  • The novel technique was developed to mitigate complications associated with larger bone tunnels required for cortical buttons.
  • The technique aims to provide superior horizontal and vertical stability compared to existing methods.
  • Potential for restoring native AC joint kinematics through enhanced stability.

Conclusions:

  • The proposed arthroscopic CC fixation technique using all-suture anchors offers a promising alternative for treating AC joint dislocations.
  • This method may effectively address limitations of cortical button fixation, such as horizontal instability and subsidence.
  • The technique is designed to restore optimal biomechanical function and kinematics of the AC joint.
