Methods for Studying Drug Absorption: In vitro01:16

Methods for Studying Drug Absorption: In vitro

648
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...

Sign Convention01:30

Sign Convention

3.6K
When analyzing a beam subjected to various loads, it is crucial to understand the internal forces and moments generated within the structure. These internal forces can be broadly classified into normal forces, shear forces, and bending moments. To determine these forces and moments, we use the method of sections and apply a specific sign convention based on their direction and the side of the section being analyzed.
The normal force acts perpendicular to the beam's cross-section and can...

Sampling Plans

1.0K
Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Enolate Mechanism Conventions01:15

Enolate Mechanism Conventions

3.0K
When a carbonyl compound is treated with a strong base, the α position gets deprotonated to give a resonance-stabilized intermediate called an enolate. Enolates are ambident nucleophiles because they possess two nucleophilic sites that can attack an electrophile owing to the delocalization of the negative charge between the α carbon and oxygen atoms. When the oxygen atom attacks an electrophile, it is called O-attack, whereas electrophilic attack via the α carbon is known as...

Planning Nursing Care I

6.1K
The planning phase of the nursing process helps nurses set priorities, outline patient-centered goals and expected outcomes, and tailor nursing interventions to align with the aligned care plan. Through the planning phase, the nurse applies critical thinking skills to align and develop interventions according to the patient's needs. It provides continuity of care allowing patients to receive the maximum benefit from treatment. It serves as a pilot plan for allocating individual staff to a...

Rous Sarcoma Virus (RSV) and Cancer

6.4K
Rous Sarcoma virus or RSV was discovered by F. Peyton Rous in the year 1911 as a filterable transmissible agent that could cause tumors in chickens. He won a Nobel Prize for this discovery in 1966. His experiments clearly demonstrated that some cancers could be caused by infectious agents and led to the discovery of many more cancer-causing viruses in animals as well as humans.
RSV is a retrovirus that contains two copies of a plus-strand  RNA genome. Its genome consists of four main open...

Area of Science:

  • Surgical Oncology
  • Medical Imaging
  • Biomedical Engineering

Background:

  • Accurate surgical planning is crucial for effective tumor resection.
  • Traditional methods rely on 2D imaging and manual measurements, which can have limitations.
  • Advancements in 3D imaging and navigation technologies offer potential improvements in surgical precision.

Purpose of the Study:

  • To conduct an in vitro comparative study of different surgical planning and execution methods for sarcoma resection.
  • To evaluate the efficacy of 2D versus 3D planning, with and without navigation assistance.

Main Methods:

  • Comparative in vitro study.
  • Method 1: 2D digital image planning and freehand execution (ruler and caliper).
  • Method 2: 3D planning and freehand execution (ruler and caliper).
  • Method 3: 3D planning and execution guided with surgical navigation.

Main Results:

  • 3D planning and navigated procedures demonstrated potential advantages over 2D methods.
  • Freehand techniques, even with 3D planning, may be less precise than navigated approaches.
  • Navigation-assisted 3D planning offers enhanced accuracy in simulated sarcoma resection.

Conclusions:

  • 3D planning combined with surgical navigation may lead to more precise sarcoma resection.
  • Navigated 3D planning represents a promising advancement in surgical oncology.
  • Further in vivo studies are warranted to confirm these in vitro findings.
