Retrieval01:12

Retrieval

444
Retrieval is the process of getting information out of memory storage and back into conscious awareness. This ability is essential for daily tasks like brushing hair and teeth, driving to work, and performing job duties. Retrieval occurs in three ways: recall, recognition, and relearning.
Recall involves accessing information without cues, such as during an essay test, where individuals must retrieve facts and concepts from memory unaided. Another example is remembering the name of a colleague...

ER Retrieval Pathway01:45

ER Retrieval Pathway

4.8K
In the secretory pathway, vesicles transport proteins from one cellular compartment to another in forward transport to deliver the protein to its correct location. Occasionally, misfolded proteins and incorrect proteins escape their original compartments, and a retrieval pathway is used to return the escaped proteins to their original compartment.
The ER uses many checkpoints to prevent the entry of incorrectly folded or a resident protein as cargo onto a transport vesicle. These mechanisms...

Plant Cell Wall

60.3K
The plant cell wall gives plant cells shape, support, and protection. As a cell matures, its cell wall specializes according to the cell type. For example, the parenchyma cells of leaves possess only a thin, primary cell wall.

Plant Cell Wall01:07

Plant Cell Wall

7.6K
Plant cells have a cell wall, a rigid outer covering that protects the cell and provides shape and support. During cell division, a mixture of enzymes, proteins, and glucose molecules is transported via vesicles to the center of the cell. These vesicles continuously fuse and build a cell plate between the dividing cells. As the cell plate matures, new polysaccharides are added to it to form the cell walls of the daughter cells. The predominant polysaccharide in the cell wall is cellulose, made...

Composite Masonry Walls01:18

Composite Masonry Walls

1.7K
Composite masonry walls combine multiple wythes of the same or different masonry materials to create a unified structure. These walls feature wythes that are bonded together either through mortar-filled collar joints, grouted spaces, or more commonly, with rigid metal ties and reinforcements, with the use of masonry header units being rare. Metal ties are preferred because they effectively minimize water penetration, as these walls primarily absorb moisture and then release it into the...

Masonry Cavity Walls01:26

Masonry Cavity Walls

1.5K
Cavity walls feature a hollow space between the outer and inner wythes, connected only by corrosion-resistant metal ties. When water seeps through the outer wythe, it descends within this cavity, intercepted by flashing and eventually exiting through weep holes. To enhance moisture resistance, the inner wythe's cavity side often receives damp-proofing, doubling as an air barrier. The cavity can also house insulation to mitigate heat transfer.
Maintaining a clean cavity during construction...

Area of Science:

  • Biomedical Engineering
  • Computational Mechanics

Background:

  • Cerebral mechanical emboli retrieval devices (MERDs) are crucial for interventional thrombectomy.
  • Effective wall apposition of MERDs is vital for capturing emboli in tortuous intracranial vessels.
  • Deterioration of wall apposition can occur during embolus capture and device migration.

Purpose of the Study:

  • To computationally evaluate the wall apposition of a novel MERD.
  • To analyze the structural behavior and strain distribution of the MERD during migration in curved vessels.
  • To assess the device's performance under simulated interventional conditions.

Main Methods:

  • Utilized commercial finite element analysis (FEA) solver ABAQUS 6.10 Standard.
  • Employed a user subroutine (UMAT/Nitinol) for material property simulation.
  • Investigated the influence of contacting interference loadings on device deformation and strain.

Main Results:

  • The middle segment of the MERD demonstrated significant contraction or collapse within curved vessels.
  • Peak strain was observed in the apex flow-prone region.
  • Strain levels were found to remain within safe operational limits.

Conclusions:

  • The MERD's structural integrity and wall apposition require further optimization for complex intracranial anatomy.
  • FEA provides a valuable approach for evaluating MERD performance and guiding design improvements.
  • The study highlights the trade-offs between device flexibility and stability during thrombectomy.
