DNA Isolation01:24

DNA Isolation

45.1K
DNA isolation protocols can be fast and straightforward or complex and time-consuming depending on the type and quality of DNA required for further processing. For example, plasmid DNA extraction is a bit more complicated than genomic DNA extraction because of the need for an appropriate lysis method to separate plasmid DNA from gDNA during isolation. However, for specific applications, such as long-range DNA sequencing that require a good yield of high- quality DNA samples, we need to follow...

DNA from cells is required for many biotechnology and research applications, such as molecular cloning. To remove and purify DNA from cells, researchers use various methods of DNA extraction. While the specifics of different protocols may vary, some general concepts underlie the process of DNA extraction.

Overview Of Cell Separation And Isolation01:20

Overview Of Cell Separation And Isolation

7.6K
Cell separation was first achieved in 1964 by S. H. Seal, who separated large tumor cells from the smaller blood cells using filtration. Two years later, Pohl and Hawk performed experiments on how cells respond differently to a nonuniform electric field based on the cell type. Such observations were the inception of cell separation methods, which allow isolating a single cell type from a heterogeneous sample.

Cyclic Processes And Isolated Systems

3.5K
A thermodynamic system with zero heat exchange and work is an isolated system. For these systems, the internal energy remains constant.
In the case of a non-isolated system, the change in the internal energy is zero only if the process is cyclic. A thermodynamic process is considered cyclic if the system undergoes a series of changes and returns to its initial state. 
Consider a cyclic process that returns to its initial state, undergoing a four-step process. The heat transfer along each...

Techniques for Isolation of Pure Cultures

2.5K
Microorganisms are routinely cultured in the laboratory using various techniques to isolate, grow, and quantify them for further study. These methods rely on inoculating microorganisms into a suitable growth medium under aseptic conditions to prevent contamination. Depending on the objective, inoculation can involve direct transfer or the use of diluted bacterial suspensions as the inoculum.Streak-Plate Method for IsolationThe streak-plate method is a common technique for obtaining pure...

Reduced Mass Coordinates: Isolated Two-body Problem

2.4K
In classical mechanics, the two-body problem is one of the fundamental problems describing the motion of two interacting bodies under gravity or any other central force. When considering the motion of two bodies, one of the most important concepts is the reduced mass coordinates, a quantity that allows the two-body problem to be solved like a single-body problem. In these circumstances, it is assumed that a single body with reduced mass revolves around another body fixed in a position with an...

Summary

Isolated subtalar arthrodesis via a sinus tarsi approach is a safe and effective surgical technique for hindfoot pathology. This procedure demonstrates high fusion rates and positive functional outcomes in adult patients.

Area of Science:

  • Orthopedic Surgery
  • Foot and Ankle Surgery

Background:

  • Isolated subtalar arthrodesis using a sinus tarsi approach with cannulated screw fixation is a recognized treatment for specific hindfoot conditions.
  • This surgical technique is considered safe, reproducible, and effective in adult populations.

Purpose of the Study:

  • To describe the surgical technique for isolated subtalar arthrodesis through a sinus tarsi approach.
  • To highlight the safety, reproducibility, and effectiveness of this procedure.

Main Methods:

  • The procedure involves comprehensive preoperative planning, specific patient positioning, and a longitudinal incision.
  • The subtalar joint is accessed by reflecting the extensor digitorum brevis, followed by meticulous joint preparation.
  • Reduction and fixation are achieved with cannulated screws, with the joint set at 5° of valgus.
