In Vitro Drug Dissolution: Alternative Methods01:17

In Vitro Drug Dissolution: Alternative Methods

242
Alternative drug dissolution methods include the rotating bottle, intrinsic dissolution test, peristalsis, and the Franz diffusion cell method. The rotating bottle method involves meticulously rotating tightly capped controlled-release beads in a temperature-controlled bath. Periodic decanting of samples allows for residue assay, followed by refilling with fresh medium and testing at various pH levels to emulate the gastrointestinal tract conditions.In contrast, the intrinsic dissolution test...

Dimensional Analysis03:40

Dimensional Analysis

65.0K
Dimensional analysis, also known as the factor label method, is a versatile approach for mathematical operations. The main principle behind this approach is: the units of quantities must be subjected to the same mathematical operations as their associated numbers. This method can be applied to computations ranging from simple unit conversions to more complex and multi-step calculations involving several different quantities and their units.

Methods for Studying Drug Absorption: In vitro

626
In vitro experiments are crucial for understanding the transport and absorption of drugs through biological materials. These studies employ varied methods such as the diffusion cell method, the everted sac technique, and the everted ring technique.
The diffusion cell method uses a two-compartment cell, including a donor compartment with the drug solution, which simulates the environment where the drug is applied, and a receptor compartment with a buffer solution, which simulates the environment...

Simple Pendulum01:10

Simple Pendulum

8.1K
A simple pendulum consists of a small diameter ball suspended from a string, which has negligible mass but is strong enough to not stretch. In our daily life, pendulums have many uses, such as in clocks, on a swing set, and on a sinker on a fishing line. 
The period of a simple pendulum depends on two factors: its length and the acceleration due to gravity. The period is completely independent of any other factors, such as mass or maximum displacement. For small displacements, a pendulum is...

Liver Histology

4.5K
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.
Hepatocytes perform a variety of essential functions. They secrete...

Liver Physiology01:30

Liver Physiology

3.8K
The liver, an essential organ in the human body, performs over 200 vital functions that can be broadly categorized into metabolic, hematological, endocrine regulation, and bile production.
Metabolic Regulation:
The liver is the central organ involved in regulating blood composition. It stabilizes blood glucose levels, maintaining them within the range of  70–110 mg/dL. When these levels drop, the liver breaks down glycogen reserves and releases glucose into the bloodstream. It can...

Area of Science:

  • Biomaterials Science
  • Regenerative Medicine
  • Tissue Engineering

Background:

  • Organ reengineering requires functional scaffolds.
  • Previous methods for decellularizing rat livers took 72 hours, leading to matrix protein loss.
  • A faster method is needed to preserve scaffold integrity.

Purpose of the Study:

  • To develop a rapid, naturally derived 3D liver scaffold.
  • To preserve the microvascular system and key extracellular matrix proteins.
  • To create a tool for advanced preclinical drug development.

Main Methods:

  • Sequential perfusion of whole rat livers with mild tensioactive substances.
  • Cellular component removal while preserving laminin, collagen I, IV, and fibronectin.
  • Assessment of scaffold integrity under fluid flow and preservation of growth factors.

Main Results:

  • A 3D naturally derived liver scaffold was obtained within 60 minutes.
  • The scaffold maintained an intact microvascular system capable of withstanding fluid flow.
  • Major extracellular matrix proteins and growth factor islets were preserved.

Conclusions:

  • This rapid method yields a robust, naturally derived liver scaffold.
  • The scaffold retains essential structural and biochemical cues for cell function.
  • This bioengineered scaffold is a promising tool for in vitro systems and preclinical drug testing.
