Contact-dependent Signaling01:19

Contact-dependent Signaling

46.9K
Contact-dependent signaling, as the name suggests, requires that communicating cells be in direct contact with each other. This is achieved either through receptor-ligand interactions or by specialized cytoplasmic channels that allow the flow of small molecules between cells. In animal cells, channels called gap junctions facilitate contact-dependent signaling in certain tissues, whereas, plasmodesmata perform a similar function in plants.

Contact Angle

When a solid is dipped inside a liquid, the liquid surface becomes curved near the contact. For some solid–liquid interfaces, the liquid is pulled up along the solid, while for others, the liquid surface is convex or depressed near the solid surface. This phenomenon can be explained using the concept of cohesive and adhesive forces.
The adhesive force is the molecular force between molecules of different materials, that is, between the molecules of the solid and the liquid. The cohesive...

Members Made of Elastoplastic Material

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...

Genetic Material

3.3K
Within the human body, a complex and detailed system of trillions of cells works in unison to sustain life. Each cell houses a nucleus, which contains 46 chromosomes divided into 23 pairs. Chromosomes are highly coiled structures made of the genetic material DNA. These chromosomes are essential carriers of genetic information, with half inherited from the mother through her egg and the other half from the father's sperm, combining to create the unique genetic makeup of an individual.

Bending of Members Made of Several Materials

In analyzing a structural member composed of two different materials with identical cross-sectional areas, it is crucial to understand how their distinct elastic properties affect the member's response under load. The analysis involves assessing stress and strain distributions using the transformed section concept, which accounts for variations in material properties.
Hooke's Law determines stress in each material, stating that stress is proportional to strain but varies due to each material's...

In this lesson, determine the ratio of the maximum bending moments applied to two metal pipes, given that both pipes can withstand a maximum stress of 100 MPa. Both pipes have an outer radius of 1.8 cm. Pipe A has an inner radius of 1.5 cm, and Pipe B has an inner radius of 1 cm. The ratio of the maximum bending moment applied to two metallic pipes, each with a different inner and outer radius, is determined by considering their dimensions. The inner radius of the first pipe is 1.5 cm, and for...

Area of Science:

  • Oral Medicine
  • Dental Materials Science
  • Allergology

Background:

  • Epidemiological data on dental material allergies is scarce.
  • Previous studies, like the German Oral Health Study (DMS V), have not adequately addressed this issue.
  • Understanding the prevalence and symptoms of oral allergies is crucial for patient care.

Purpose of the Study:

  • To determine the frequencies and symptoms of allergies to dental materials.
  • To investigate the types of dental materials causing allergic reactions.
  • To identify common oral manifestations of these allergies.

Main Methods:

  • An observational study was conducted using data from a specialized consultation hour for oral mucosa allergies and material incompatibilities.
  • Clinical patient data, including objective mucosal findings and subjective complaints, were systematically collected since 2012.
  • 86 patients (83.7% female, mean age 63) with oral symptoms of contact allergy were included.

Main Results:

  • Metal allergies, particularly to nickel and cobalt, were most prevalent.
  • Allergies to cosmetic ingredients and composites were also common.
  • Methacrylate-containing denture resins accounted for 5% of allergies.
  • 52.4% of patients exhibited mucosal changes, with contact stomatitis (54.5%) and oral lichenoid lesions (20.5%) being most frequent.
  • 86% of patients reported subjective complaints, primarily oral pain and burning sensations.

Conclusions:

  • Dental material allergies, especially to metals, are a significant concern.
  • Contact stomatitis and oral lichenoid lesions are common oral manifestations.
  • Comprehensive dental allergy history, clinical examination, material analysis, and psychogenic disorder screening are essential for diagnosis.
