Contact Angle01:13

Contact Angle

22.1K
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...

Contact-dependent Signaling01:19

Contact-dependent Signaling

47.6K
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.
Gap Junctions
In animal cells, gap junctions are formed...

Transmission-based Precautions I: Contact, Enteric, and Droplets

4.7K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Lattice Centering and Coordination Number

11.7K
The structure of a crystalline solid, whether a metal or not, is best described by considering its simplest repeating unit, which is referred to as its unit cell. The unit cell consists of lattice points that represent the locations of atoms or ions. The entire structure then consists of this unit cell repeating in three dimensions. The three different types of unit cells present in the cubic lattice are illustrated in Figure 1.

Improving Translational Accuracy

Base complementarity between the three base pairs of mRNA codon and the tRNA anticodon is not a failsafe mechanism. Inaccuracies can range from a single mismatch to no correct base pairing at all. The free energy difference between the correct and nearly correct base pairs can be as small as 3 kcal/ mol. With complementarity being the only proofreading step, the estimated error frequency would be one wrong amino acid in every 100 amino acids incorporated. However, error frequencies observed in...

Summary
This summary is machine-generated.

Carmine, a natural food additive, can cause immediate and delayed allergic reactions, including systemic contact dermatitis. Identifying carmine intolerance is crucial for managing recalcitrant dermatitis through elimination diets and topical treatments.

Area of Science:

  • Allergy and Immunology
  • Dermatology
  • Food Science

Background:

  • Carmine is a common natural food additive derived from cochineal insects.
  • It is known to cause immediate hypersensitivity reactions.
  • Systemic contact dermatitis can occur following re-exposure to allergens.

Purpose of the Study:

  • To highlight carmine as a potential trigger for systemic contact dermatitis.
  • To emphasize the importance of considering carmine intolerance in recalcitrant dermatitis cases.
  • To suggest diagnostic and management strategies for carmine-induced reactions.

Main Methods:

  • Review of clinical presentations of carmine hypersensitivity.
  • Discussion of diagnostic approaches including patch testing.
  • Consideration of elimination diets and topical product avoidance.

Main Results:

  • Carmine can induce both immediate and delayed hypersensitivity reactions.
  • Systemic contact dermatitis is a recognized manifestation of carmine intolerance.
  • Positive carmine intolerance history and patch tests are significant indicators.

Conclusions:

  • Carmine intolerance should be suspected in patients with unexplained or recalcitrant dermatitis.
  • Diagnostic elimination of carmine from diet and topical products is recommended.
  • Management involves identifying and avoiding carmine-containing foods and products.
