Extraction: Effects of pH00:53

Extraction: Effects of pH

1.3K
Consider a neutral form of an amine, B, with a partition coefficient, K, in a liquid mixture containing organic and aqueous phases. The pH of the aqueous phase affects the charge on acidic and basic solutes, and the charged form is usually more soluble in the aqueous phase. Suppose the conjugate acid form of the amine is soluble only in the aqueous phase while the base form is soluble in both phases. Then the distribution coefficient, D, can be given as the ratio of amine concentration in the...

Extraction: Advanced Methods

Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is...

Extraction: Partition and Distribution Coefficients

The distribution law or Nernst's distribution law is the law that governs the distribution of a solute between two immiscible solvents. This law, also known as the partition law, states that if a solute is added to the mixture of two immiscible solvents at a constant temperature, the solute is distributed between the two solvents in such a way that the ratio of solute concentrations in the solvents remains constant at equilibrium.
For extracting a solute from an aqueous phase into an...

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.

What is Glycolysis?00:56

What is Glycolysis?

176.4K
Overview
Cells make energy by breaking down macromolecules. Cellular respiration is the biochemical process that converts "food energy" (from the chemical bonds of macromolecules) into chemical energy in the form of adenosine triphosphate (ATP). The first step of this tightly regulated and intricate process is glycolysis. The word glycolysis originates from the Latin glyco (sugar) and lysis (breakdown). Glycolysis serves two main intracellular functions: generating ATP and generating...

Hindsight bias leads you to believe that the event you just experienced was predictable, even though it really wasn’t. In other words, you knew all along that things would turn out the way they did. Can you relate this to the phrase "Hindsight is 20/20" now?

Area of Science:

  • Cardiology
  • Medical Devices
  • Interventional Cardiology

Background:

  • Leadless pacemakers offer advantages but pose management challenges at end-of-service or with complications.
  • Established transvenous lead extraction methods lack standardization for leadless devices.
  • Increasing use of leadless pacing necessitates a structured approach to device removal.

Purpose of the Study:

  • To propose a systematic framework for transvenous leadless pacemaker extraction (TLLE).
  • To define indications, procedural strategies, risk assessment, and institutional requirements for TLLE.
  • To consolidate current knowledge on TLLE for clinical application.

Main Methods:

  • Review of existing literature on leadless pacemaker extraction techniques.
  • Summarization of clinical indications for TLLE, including device failure, dislocation, infection, and upgrades.
  • Analysis of procedural strategies, focusing on femoral access and snare-based techniques, tailored to device specifics.

Main Results:

  • High success rates reported in literature for TLLE procedures.
  • Identified potential complications include cardiac perforation, tamponade, tricuspid valve injury, and embolization.
  • Patient selection and pre-procedural imaging are crucial for decision-making.

Conclusions:

  • A structured approach to TLLE is clinically relevant due to increasing leadless pacemaker use.
  • Balancing procedural risks with the implications of device abandonment is key for patient management.
  • Standardized TLLE protocols are needed to ensure safe and effective leadless pacemaker management.
