Lateralization01:28

Lateralization

1.0K
Brain lateralization refers to the division of mental processes and functions between the two hemispheres of the brain, a phenomenon that optimizes neural efficiency and underpins complex abilities in humans. This specialization allows each hemisphere to perform tasks where it has a comparative advantage, facilitating more refined cognitive capabilities across different domains.

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

25.9K
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 Effect01:03

Serial Position Effect

543
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...

Position Vectors

1.9K
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

19.9K
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...

Summary

Patients with lateral placenta previa (PP) experienced significantly less blood loss during cesarean section compared to those with anterior or posterior PP. Anteriorly dominant lateral PP cases showed higher blood loss than posterior dominant cases.

Area of Science:

  • Obstetrics and Gynecology
  • Maternal-Fetal Medicine
  • Diagnostic Imaging

Background:

  • Placenta previa (PP) is a condition where the placenta partially or completely covers the cervix.
  • Lateral PP, with the placenta mainly on the uterine wall, requires specific clinical characterization.
  • Understanding perinatal outcomes associated with different PP localizations is crucial for patient management.

Purpose of the Study:

  • To characterize lateral placenta previa (PP) by analyzing perinatal outcomes.
  • To compare blood loss and other clinical parameters in patients with lateral PP versus non-lateral PP.
  • To investigate differences in outcomes between anteriorly and posteriorly dominant lateral PP.

Main Methods:

  • Retrospective cohort study of 98 patients with PP from January 2006 to December 2016.
  • Placental position classified using magnetic resonance imaging (MRI).
  • Comparison of blood loss at cesarean section (CS) among lateral, anterior, and posterior PP groups, and subgroups of lateral PP.

Main Results:

  • Lateral PP patients (n=30) showed significantly less blood loss at CS (median 1510 mL) compared to non-lateral PP (anterior/posterior, n=68; median 1975 mL; p=.02).
  • No significant differences in rates of assisted reproductive technology conception, prior CS, antepartum bleeding, or placenta accreta spectrum were found.
  • Patients with anteriorly dominant lateral PP bled significantly more (median 2430 mL) than those with posteriorly dominant lateral PP (median 1170 mL; p=.002).

Conclusions:

  • Lateral placenta previa is associated with significantly reduced intraoperative blood loss during cesarean delivery compared to anterior or posterior placenta previa.
  • The dominant position (anterior vs. posterior) within lateral placenta previa influences blood loss, with anterior dominance correlating with higher bleeding.
