Microtubule Instability02:17

Microtubule Instability

6.3K
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...

piRNA - Piwi-interacting RNAs

7.7K
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...

Nonconscious Mimicry01:13

Nonconscious Mimicry

Nonconscious mimicry occurs when individuals alter their mannerisms to match the behaviors and expressions of those nearby, without intention.

In- and Out-Groups

43.7K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Overview of DNA Repair02:25

Overview of DNA Repair

33.8K
In order to be passed through generations, genomic DNA must be undamaged and error-free. However, every day, DNA in a cell undergoes several thousand to a million damaging events by natural causes and external factors. Ionizing radiation such as UV rays, free radicals produced during cellular respiration, and hydrolytic damage from metabolic reactions can alter the structure of DNA. Damages caused include single-base alteration, base dimerization, chain breaks, and cross-linkage.

    Summary
    This summary is machine-generated.

    This study found that postural instability did not directly cause motion sickness in individuals, even when they could not adapt their posture. Further research is needed to understand the causes of motion sickness.

    Area of Science:

    • Human physiology
    • Aerospace medicine
    • Human factors psychology

    Background:

    • Motion sickness significantly impacts military personnel due to extreme operational demands.
    • Understanding motion sickness mechanisms is crucial for developing effective countermeasures.
    • This study explored the role of postural instability in motion sickness etiology.

    Purpose of the Study:

    • To investigate the causal relationship between postural instability and motion sickness.
    • To test the predictions of the postural instability theory of motion sickness.
    • To examine how active versus passive postural control affects sickness symptoms.

    Main Methods:

    • Subjects experienced various motion profiles under both active (self-adapted posture) and passive (fixed posture) conditions.
    • Postural stability was quantified using sample entropy.
    • Simulator Sickness Questionnaire (SSQ) assessed symptom severity.

    Main Results:

    • Active postural control led to greater stability (M = 0.179) compared to passive control (M = 0.136).
    • Sickness symptoms increased over time in both conditions.
    • No significant difference in SSQ scores was found between active and passive conditions.
    • No correlation was observed between postural instability measures and reported symptoms.

    Conclusions:

    • The findings do not support postural instability as the primary cause of motion sickness.
    • Current evidence suggests other factors are more critical in motion sickness development.
    • Further research is required to fully understand the complex etiology of motion sickness.
