Elastin is Responsible for Tissue Elasticity01:12

Elastin is Responsible for Tissue Elasticity

2.4K
Elastic fiber contains the protein elastin along with lesser amounts of other proteins and glycoproteins. The main property of elastin is that it will return to its original shape after being stretched or compressed. Elastic fibers are prominent in elastic tissues found in skin and the elastic ligaments of the vertebral column.
Ligaments and tendons are made of dense regular connective tissue, but in ligaments not all fibers are parallel. Dense regular elastic tissue contains elastin fibers and...

Members Made of Elastoplastic Material

131
The behavior of elastoplastic materials under bending stresses, particularly in structural members with rectangular cross-sections, is crucial for predicting material responses and understanding failure modes. Initially, when a bending moment is applied, the stress distribution across the section follows Hooke's Law and is linear and elastic. This distribution means the stress increases from the neutral axis to the maximum at the outer fibers, up to the elastic limit.
As the bending moment...

Cell-matrix's Response to Mechanical Forces01:13

Cell-matrix's Response to Mechanical Forces

2.7K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue. 
Anchoring junctions mechanically attach a cell to the...

Cell Motility through Blebbing01:16

Cell Motility through Blebbing

2.0K
Blebs are a type of membrane protrusion formed by the internal hydrostatic pressure of the cytoplasm. Blebs are observed in several cell types, including fibroblasts, immune cells, and single-celled organisms like the amoeba. The primary function of blebs is cell locomotion and apoptosis, but they are also found during necrosis and cell division. The life cycle of a bleb comprises an initiation phase followed by the expansion and retraction phases.

Fibril-associated Collagen01:11

Fibril-associated Collagen

2.6K
Fibril-associated collagens are a type of collagens present in the extracellular matrix with interrupted triple helices or FACIT (Fibril-associated collagens interrupted triple-helices). FACIT help connect and attach the collagen fibrils with each other as well as with other proteins of the extracellular matrix.
For example, the type II collagen fibrils in cartilage have covalently bound type IX fibril-associated collagens at regular intervals. Other types of fibril-associated collagens are...

Summary
This summary is machine-generated.

Linear focal elastosis (LFE) presents as asymptomatic, striae-like bands on the trunk. Histopathology reveals increased dermal elastic fibers, with treatment often being ineffective.

Area of Science:

  • Dermatology
  • Histopathology
  • Medical Research

Background:

  • Linear focal elastosis (LFE) is a rare, acquired skin condition.
  • Its exact cause (pathogenesis) remains unclear.
  • LFE manifests clinically as multiple, yellowish, elevated, striae-like lines on the posterior trunk.

Purpose of the Study:

  • To provide dermatologists with insights into Linear focal elastosis.
  • To discuss the clinical and histopathological features of LFE.
  • To highlight the diagnostic challenges and poor treatment response associated with LFE.

Main Methods:

  • Clinical observation of LFE presentation.
  • Histopathological examination of skin biopsies.
  • Review of existing literature on elastotic conditions.

Main Results:

  • LFE is characterized by asymptomatic, horizontal, striae-like bands.
  • The defining histopathological feature is a focal increase in dermal elastic fibers.
  • Striae distensae is the primary condition in the differential diagnosis.

Conclusions:

  • Linear focal elastosis is a distinct, benign elastotic disorder.
  • Accurate histopathological identification is crucial for diagnosis.
  • Current treatment options for LFE show limited efficacy.
