Microtubule Instability02:17

Microtubule Instability

6.1K
Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Virtual Work01:20

Virtual Work

1.4K
The principle of virtual work states that if a body is in static and dynamic equilibrium, then the sum of all the virtual work done by all external forces and couple moments for any given virtual displacement must be zero.
In static equilibrium, a body can experience an imaginary or virtual movement, such as displacement or rotation. The virtual work done by a force is equal to the dot product of force and virtual displacement in the direction of the force. When it comes to virtually rotating a...

Principle of Virtual Work: Problem Solving

1.6K
The principle of virtual work is an essential concept in the field of mechanics and engineering. This is used to solve problems related to the equilibrium of a structure or system. It is based on the assumption that if a system is in equilibrium, the work done by all the forces during a virtual displacement is zero. This principle is applied by considering virtual displacements of the system and the corresponding work done by internal and external forces.
To apply the principle of virtual work,...

Virtual Work for a System of Connected Rigid Bodies

744
Virtual work is a powerful method used to solve problems involving several connected rigid bodies. When the system is in equilibrium, virtual work is zero. This allows the calculation of the resulting forces when a system undergoes a virtual displacement. When attempting to analyze such a system, first, use a free-body diagram, where an independent coordinate represents the configuration of the links, and mark its deflected position resulting from the positive virtual displacement.

Imaging Studies III: Gastrointestinal Motility Studies and Virtual Colonoscopy

400
This lesson explores three gastrointestinal imaging techniques: radionuclide testing, colonic transit studies, and virtual colonoscopy.
Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
In gastric emptying studies, a meal's liquid and...

piRNA - Piwi-interacting RNAs02:57

piRNA - Piwi-interacting RNAs

7.6K
PIWI-interacting RNAs, or piRNAs, are the most abundant short non-coding RNAs. More than 20,000 genes have been found in humans that code for piRNAs while only 2000 genes have been found for miRNAs. piRNAs can act at the transcriptional and post-transcriptional levels and have a vital role in silencing transposable elements present in germ cells. They are also involved in epigenetic silencing and activation. Previously, they were thought to function only in germ cells but new evidence suggests...

Area of Science:

  • Neuroscience
  • Human-Computer Interaction
  • Biomechanics

Background:

  • Virtual reality (VR) adoption is increasing, yet safety guidelines often lack detail.
  • Users may underestimate the potential risks associated with VR use.
  • Understanding VR's physiological effects is crucial for safe implementation.

Purpose of the Study:

  • To assess the impact of virtual reality (VR) on postural balance in healthy adults.
  • To quantify balance changes during different levels of VR immersion.

Main Methods:

  • Fifteen healthy adults underwent the Sensory Organization Test (SOT) to measure Mean Equilibrium Score (MES).
  • Participants completed SOT under normal conditions and while engaging with VR programs categorized by difficulty (Easy, Average, Challenging).

Main Results:

  • Mean Equilibrium Scores (MES) were significantly lower during VR use compared to baseline (Condition 1 vs. Condition 2).
  • Challenging and Average VR programs led to significant balance decrements compared to an eyes-open condition.
  • Even Easy VR programs showed a trend towards reduced balance, though not statistically significant compared to eyes-open.

Conclusions:

  • Virtual reality usage can induce significant postural imbalance in users.
  • Objective measures are required to assess and mitigate VR-related balance deficits.
  • Further investigation into VR's effects on balance is warranted for safety protocols.
