Fixation and Sectioning01:03

Fixation and Sectioning

7.5K
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...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

671
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...

The Roles of Bacteria and Fungi in Plant Nutrition

47.1K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

C4 Pathway and CAM01:27

C4 Pathway and CAM

48.9K
Most plants use the C3 pathway for carbon fixation. However, some plants, such as sugar cane, corn, and cacti that grow in hot conditions, use alternative pathways to fix carbon and conserve energy loss due to photorespiration. Photorespiration is the process that occurs when the oxygen concentration is high. Under such conditions, the rubisco enzyme in the Calvin cycle binds O2 instead of CO2, which halts photosynthesis and consumes energy.

The Nitrogen Cycle01:49

The Nitrogen Cycle

59.6K
Nitrogen atoms, present in all proteins and DNA, are recycled between abiotic and biotic components of the ecosystem. However, the primary form of nitrogen on Earth is nitrogen gas, which cannot be used by most animals and plants. Thus, nitrogen gas must first be converted into a usable form by nitrogen-fixing bacteria before it can be cycled through other living organisms. The use of nitrogen-containing fertilizers and animal waste products in human agriculture has greatly influenced the...

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery
  • Trauma Surgery

Background:

  • Complex talus pathologies, such as infection, present significant treatment challenges.
  • Arthrodesis is a surgical procedure to fuse bones, often used for severe joint damage or deformity.
  • The Ilizarov fixator is an external device used for bone stabilization and reconstruction.

Purpose of the Study:

  • To evaluate the efficacy of arthrodesis with an Ilizarov fixator for tibiocalcaneana.
  • To assess outcomes in patients with complex talus pathologies, specifically infection.

Main Methods:

  • Twelve patients with talus infection underwent tibiocalcaneana arthrodesis.
  • Surgical techniques included modified Reckling (6 patients) and modified Catagni Ilizarov (6 patients).
  • Outcomes were assessed using the AOFAS scale and patient satisfaction surveys.

Main Results:

  • Achieved 100% union rate with a mean healing time of 6 months.
  • Mean external fixator duration was 9 months; 6 patients underwent lengthening (average 4 cm).
  • Average AOFAS score was 72.5, with all patients reporting satisfaction.

Conclusions:

  • Tibiocalcaneana arthrodesis with the Ilizarov fixator is a viable solution for complex talus pathologies like infection.
  • The procedure resulted in successful bone healing, pain reduction, and high patient satisfaction.
  • Despite a small sample size, the findings support this technique for challenging foot and ankle cases.
