Accessory Structures of the Skin: Nails01:05

Accessory Structures of the Skin: Nails

3.3K
Nails are one of the important accessory structures of the skin. They are hard, protective structures that cover the dorsal surface of the distal phalanges of fingers and toes. Nails are composed of specialized keratinized cells and serve various functions, including protection, sensation, and manual dexterity.
The main components of a nail include the following.
Nail Plate: The nail plate is the visible portion of the nail that extends beyond the fingertips or toes. It is a hard, translucent...

Fixation and Sectioning01:03

Fixation and Sectioning

7.9K
Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens.
The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

Leveling Effect01:29

Leveling Effect

1.4K
In acid-base chemistry, the leveling effect refers to the limitation imposed by the solvent on the strength of acids and bases in solution. When a base stronger than the solvent's conjugate base is used, it deprotonates the solvent until the base is entirely consumed, making it ineffective against weaker acids. Conversely, an acid stronger than the solvent's conjugate acid protonates the solvent until the acid is depleted, rendering it ineffective against weaker bases. Essentially, the...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

711
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Fixing Double-strand Breaks

14.6K
The double-stranded structure of DNA has two major advantages. First, it serves as a safe repository of genetic information where one strand serves as the back-up in case the other strand is damaged. Second, the double-helical structure can be wrapped around proteins called histones to form nucleosomes, which can then be tightly wound to form chromosomes. This way, DNA chains up to 2 inches long can be contained within microscopic structures in a cell. A double-stranded break not only damages...

Area of Science:

  • Orthopedic Surgery
  • Biomedical Engineering

Background:

  • Double-level lengthening and deformity correction often require prolonged external fixation (Ilizarov or similar devices).
  • Alternative techniques aim to reduce the duration and complications associated with external fixators.

Purpose of the Study:

  • To evaluate the efficacy and safety of double-level fixator-assisted nailing for limb deformity correction and lengthening.
  • To compare the duration of external fixation and external fixation index (EFI) with traditional external fixation methods.

Main Methods:

  • A prospective study of 23 patients (27 segments) undergoing double-level fixator-assisted nailing.
  • Comparison with a matched control group of 27 patients treated with conventional external fixation.
  • Data collected included time in fixator, EFI, and clinical outcomes (ASAMI scores).

Main Results:

  • No significant difference in mean length gain between the study group (3.9 cm) and control group (4.2 cm).
  • Significantly shorter mean time in fixator (8.6 weeks vs. 30.2 weeks) and lower mean EFI (17.7 days/cm vs. 73.4 days/cm) in the study group.
  • Excellent or good ASAMI bone and functional scores were achieved in most patients, with no infections.

Conclusions:

  • Double-level fixator-assisted nailing is a safe and effective technique for limb deformity correction and lengthening.
  • This method significantly reduces the time patients spend in external fixation and lowers the EFI.
  • It offers an accurate, cost-effective treatment option with improved patient outcomes.
