Journal Bearings01:23

Journal Bearings

1.3K
Journal bearings are mechanical components that support and provide lateral stability to rotating shafts and axles. They are crucial in reducing friction, wear, and vibration in machinery such as engines, turbines, and pumps. The principle behind journal bearings is forming a thin lubricant film between the bearing surface and the rotating shaft, which minimizes direct contact and reduces frictional forces.
To better understand the concept of journal bearings, consider a rope winch with dry or...

Tissues

Cells with similar structure and function are grouped into tissues. A group of tissues with a specialized function is called an organ. There are four main types of tissue in vertebrates: epithelial, connective, muscle, and nervous.

Dietary Connections

63.9K
In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Internal Receptors01:31

Internal Receptors

75.7K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

The Scientific Method

274.0K
The scientific method is a detailed, empirical problem-solving process used by biologists and other scientists. This iterative approach involves formulating a question based on observation, developing a testable potential explanation for the observation (called a hypothesis), making and testing predictions based on the hypothesis, and using the findings to create new hypotheses and predictions.
Generally, predictions are tested using carefully-designed experiments. Based on the outcome of these...

Area of Science:

  • Biomedical Engineering
  • Pharmacology
  • Materials Science

Background:

  • Tissue sealants are crucial in wound management and surgical applications.
  • Maintaining effective antibiotic concentrations at tissue sites is vital for preventing infections.
  • Air-fluidised beds (AFBs) present unique challenges for drug delivery and retention.

Purpose of the Study:

  • To quantify antibiotic concentrations within common tissue sealants.
  • To evaluate the impact of air-fluidised bed environments on sealant and antibiotic integrity.
  • To provide data for optimizing antibiotic-eluting tissue sealant formulations.

Main Methods:

  • In vitro testing of commercially available tissue sealants.
  • Incorporation of model antibiotics into sealant formulations.
  • Exposure of sealants to simulated air-fluidised bed conditions.
  • Quantification of antibiotic release and degradation using High-Performance Liquid Chromatography (HPLC).

Main Results:

  • Antibiotic concentrations varied significantly among different sealant types.
  • Prolonged exposure to air-fluidised conditions led to a reduction in sealant integrity.
  • Significant antibiotic leaching was observed in simulated air-fluidised bed environments.
  • Degradation of certain antibiotics was accelerated under AFB conditions.

Conclusions:

  • Standard tissue sealants may not adequately maintain therapeutic antibiotic levels in air-fluidised beds.
  • Formulation strategies are needed to enhance antibiotic retention and stability in AFBs.
  • Further research is required to develop specialized antibiotic-eluting sealants for AFB applications.
