Fixation and Sectioning01:03

Fixation and Sectioning

8.0K
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

749
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...

Sustainable Development

15.2K
As the human population continues to grow and use resources, we must be mindful of our planet’s natural limits. Sustainable development provides a pathway to maintain and improve human life now while also ensuring that future generations will have the resources that they need. The long-term success of sustainability efforts rests on understanding the interplay between human actions and ecological systems.

Column Efficiency: Plate Theory01:10

Column Efficiency: Plate Theory

2.2K
Band broadening in a chromatography column is measured by its efficiency. This is determined by the number of theoretical plates (N). Theoretical plate theory states that a separation column consists of a continuous series of imaginary plates where solute equilibration occurs between stationary and mobile phases.
A higher number of theoretical plates signifies better column efficiency and improved separation capabilities. Plate height affects bandwidth and separation quality; it is inversely...

Electric Field of Parallel Conducting Plates01:16

Electric Field of Parallel Conducting Plates

1.8K
Gauss' law relates the electric flux through a closed surface to the net charge enclosed by that surface. Gauss's law can be applied to find the electric field and the charge enclosed in a region depending on its charge distribution.
Consider a cross-section of a thin, infinite conducting plate having a positive charge. For such a large thin plate, as the thickness of the plate tends to zero, the positive charges lie on the plate's two large faces. Without an external electric field, the...

Fluid Pressure over Curved Plate of Constant Width01:12

Fluid Pressure over Curved Plate of Constant Width

2.0K
When a curved plate of constant width is submerged in a liquid, the pressure acting normal to the plate varies continuously both in magnitude and direction. Calculating the magnitude and location of the resultant force at a point is often challenging for such cases. One of the methods to determine the resultant force and its location involves separately calculating the horizontal and vertical components of the resultant force. This complex calculation can be simplified by representing the...

Area of Science:

  • Orthopedic Surgery
  • Minimally Invasive Procedures
  • Surgical Anatomy

Background:

  • Acetabular fractures present complex fixation challenges.
  • Minimally invasive techniques are sought to reduce morbidity.
  • Laparoscopic approaches offer potential advantages in exposure and precision.

Purpose of the Study:

  • To assess the feasibility and reproducibility of a laparoscopic technique for acetabular fracture fixation.
  • To evaluate the use of infra-pectineal and supra-pectineal plates with laparoscopic guidance.
  • To determine the safety and efficacy of screw placement using a standardized pelvic classification.

Main Methods:

  • A standardized preperitoneal laparoscopic approach was performed on ten adult cadavers.
  • Infra-pectineal and supra-pectineal plates were inserted under laparoscopic control.
  • Screw placement was guided by an eight-zone pelvic classification system.

Main Results:

  • The laparoscopic procedure was successfully completed in 90% of cadaveric specimens.
  • Key anatomical landmarks were consistently identified, and implants were positioned as planned.
  • Mean operative time was 115 minutes, with no major vascular, visceral, or neurological injuries.

Conclusions:

  • The described laparoscopic technique for acetabular fracture fixation is feasible and reproducible.
  • This approach may serve as a minimally invasive alternative for specific acetabular fractures, especially in fragile patients.
  • Further clinical studies are warranted to validate these findings in live patients.
