In Vitro Drug Release Testing: Overview, Development and Validation01:10

In Vitro Drug Release Testing: Overview, Development and Validation

363
In vitro dissolution and drug release tests assess how quickly and how much of a drug is released from its dosage form into an aqueous medium under standardized laboratory conditions. These tests are essential tools in pharmaceutical development and quality assurance, offering insight into the drug's performance before clinical use.During formulation development, dissolution testing identifies incomplete or inconsistent drug release issues. It also supports decisions on selecting the optimal...

Reliability and Validity01:29

Reliability and Validity

14.1K
Reliability and validity are two important considerations that must be made with any type of data collection. Reliability refers to the ability to consistently produce a given result. In the context of psychological research, this would mean that any instruments or tools used to collect data do so in consistent, reproducible ways.

Data Validation01:15

Data Validation

2.1K
Method validation is a crucial process in analytical chemistry designed to confirm that a given method consistently produces reliable and high-quality results. This process is essential when a method is applied to different sample matrices or when procedural modifications are made, ensuring that the results meet acceptable standards across various applications.
Key parameters for method validation include:

Data Validation

Data validation is an essential part of a comprehensive assessment. Validation is confirming or verifying and opening the door to gathering more assessment data as it clarifies vague or unclear data. The process of checking and verifying the collected information is called data validation. The primary purpose of data validation is to ensure data is as free from error, bias, and misinterpretation as possible.
Nursing assessment guides are generally based on holistic models rather than medical...

Energy-releasing Steps of Glycolysis01:28

Energy-releasing Steps of Glycolysis

147.0K
Glycolysis is divided into two phases based on whether energy is utilized or released. While the first phase consumes ATP, the second phase produces energy in the form of ATP and NADH. The energy is released over a sequence of reactions that turns G3P into pyruvate. The energy-releasing phase—steps 6-10 of glycolysis—occurs twice, once for each of the two 3-carbon sugars produced during steps 1-5 of the first phase.
The first energy-releasing step—the 6th step of glycolysis...

Formulating and Validating Nursing Diagnosis I01:26

Formulating and Validating Nursing Diagnosis I

4.0K
A nursing diagnosis is written when the nurse recognizes a cluster of essential patient data indicating health problems treated with independent nursing interventions. The standardized terminologies of a nursing diagnosis help nurses identify and treat patients' problems. Every electronic health record that uses nursing diagnosis must employ standard diagnostic terminology. Developing an efficient, individualized care plan begins with accurate nursing diagnoses.
There are thirteen domains...

Area of Science:

  • Orthopedic Surgery
  • Musculoskeletal Imaging
  • Minimally Invasive Procedures

Background:

  • The plantaris tendon (PT) is implicated in Achilles region pain syndromes.
  • Traditional management involves open surgical resection.
  • A minimally invasive, sonographically guided technique for PT release has not been described.

Purpose of the Study:

  • To validate a sonographically guided technique for plantaris tendon release.
  • To assess feasibility in an unembalmed cadaveric model.

Main Methods:

  • Twenty cadaveric knee-ankle-foot specimens were used.
  • Sonographically guided hydrodissection and release of the PT were performed.
  • A 3.0-mm hook knife and ultrasound were utilized for the procedure.

Main Results:

  • All 20 plantaris tendon releases were completed successfully in one attempt.
  • Procedures required only a 3- to 5-mm incision.
  • Dissection confirmed complete PT release with no iatrogenic injury to the Achilles tendon or neurovascular structures.

Conclusions:

  • Sonographically guided plantaris tendon release is technically feasible.
  • The technique avoids injury to adjacent critical structures.
  • Further research is needed to evaluate its clinical application for PT-mediated pain.
