Position-effect Variegation02:32

Position-effect Variegation

7.1K
In 1928, a German botanist Emil Heitz observed the moss nuclei with a DNA binding dye. He observed that while some chromatin regions decondense and spread out in the interphase nucleus, others do not. He termed them euchromatin and heterochromatin, respectively. He proposed that the heterochromatin regions reflect a functionally inactive state of the genome. It was later confirmed that heterochromatin is transcriptionally repressed, and euchromatin is transcriptionally active chromatin.

Position and Displacement

26.8K
The position of an object defines its location relative to a convenient frame of reference at any particular time. A frame of reference is an arbitrary set of axes from which the position and motion of an object are described. Earth is often used as a frame of reference, and we often describe the position of an object as it relates to stationary objects on Earth. For example, a rocket launch could be described in terms of the position of the rocket with respect to Earth as a whole. On the other...

Serial Position Effect

563
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

Position Vectors01:29

Position Vectors

2.0K
A position vector is a fundamental concept in mathematics that helps determine the position of one point with respect to another point in space. It is a vector that describes the direction and distance between two points. Position vectors are highly useful in the field of math and science, as they help represent spatial relationships and make calculations easier.
For instance, we want to locate a point P(x, y, z) relative to the origin of coordinates O. In that case, we can define a position...

Anatomical Positions01:11

Anatomical Positions

20.6K
In anatomy, several standard anatomical positions are used as references for describing the position and orientation of different body parts. These positions help provide a common frame of reference when discussing anatomical structures. The anatomical position is the standard reference point for describing the body's position and orientation. In this position:
The body is upright, facing forward, and standing erect.
The feet are parallel and flat on the floor.
The arms are hanging by the...

Area of Science:

  • Neurosurgery
  • Medical Technology

Background:

  • Neuronavigation systems (NS) are crucial for precise lesion localization in neurosurgery.
  • Minimizing errors during navigation is essential for patient safety.

Purpose of the Study:

  • To introduce and evaluate a novel technique for patient tracker positioning in magnetic neuronavigation.
  • To ensure optimal accuracy and minimize displacement during neurosurgical procedures.

Main Methods:

  • A retrospective study of 34 patients undergoing microscopic transcranial or endoscopic endonasal surgery.
  • Patients' palatal tracker positioning was assessed for navigation accuracy.
  • Accuracy was evaluated by two neurosurgeons pre- and post-operatively.

Main Results:

  • The palatal tracker positioning technique was successful in 97% of cases (33 out of 34 patients).
  • No intraoperative or postoperative complications were associated with the palatal tracker.
  • Maximal tracking view and optimal navigation accuracy were achieved.

Conclusions:

  • Palatal positioning of the patient tracker is a safe, accurate, and feasible method for neuronavigation.
  • This technique effectively prevents device displacement without causing invasiveness or discomfort.
  • The method demonstrated a high success rate in diverse neurosurgical procedures.
