Acid Attack on Concrete01:21

Acid Attack on Concrete

757
When acids come into contact with concrete, they initiate a chemical reaction that dissolves the hydrated cement paste. This process leads to softening and structural weakening of the concrete. This issue is commonly observed in environments such as chimneys, sewers, and industrial settings. The severity of the damage increases as the pH of the water interacting with the concrete drops below 6.5. In particular, a pH under 4.5 can cause significant concrete damage.
The rate at which hydrogen...

Microtubule Instability02:17

Microtubule Instability

6.2K
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...

Sulfate Attack on Concrete01:29

Sulfate Attack on Concrete

742
Sulfate attack on concrete is a deterioration process characterized by a whitish discoloration beginning at the edges and corners, accompanied by cracking and spalling. This phenomenon occurs when sulfates react with the components of hardened concrete, forming compounds like calcium sulfate and calcium sulfoaluminate which occupy more space than the substances they replace, causing the concrete to expand and disrupt.
Sulfates from sources like soil, groundwater, or industrial effluents...

CRISPR and crRNAs02:53

CRISPR and crRNAs

19.1K
Bacteria and archaea are susceptible to viral infections just like eukaryotes; therefore, they have developed a unique adaptive immune system to protect themselves. Clustered regularly interspaced short palindromic repeats and CRISPR-associated proteins (CRISPR-Cas) are present in more than 45% of known bacteria and 90% of known archaea.
The CRISPR-Cas system stores a copy of foreign DNA in the host genome and uses it to identify the foreign DNA upon reinfection. CRISPR-Cas has three different...

Fixed Action Patterns01:06

Fixed Action Patterns

17.7K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

piRNA - Piwi-interacting RNAs02:57

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...

Summary

Migraine attacks significantly impair postural control, increasing body sway during standing. This suggests a temporary cerebellar dysfunction and altered sensory processing during acute migraine episodes.

Area of Science:

  • Neurology
  • Neuroscience
  • Vestibular System

Background:

  • Migraine is often linked to dizziness and unsteadiness.
  • Postural control during migraine attacks has not been previously studied.

Purpose of the Study:

  • To measure upright stance stability in migraine patients during acute attacks.
  • To investigate postural control changes during the ictal state of migraine.

Main Methods:

  • Prospective assessment of static balance in 30 migraine patients and 30 controls using a force platform.
  • Recordings were taken during quiet stance under varying visual and proprioceptive feedback conditions, both during attacks (ictal) and pain-free periods (interictal).

Main Results:

  • Migraine patients exhibited significantly increased postural sway during attacks compared to pain-free periods and controls.
  • Sensory re-weighting occurred, with reduced reliance on visual and proprioceptive input during ictal states.
  • Romberg and vestibular Romberg quotients remained unchanged, but were inversely correlated with headache severity.

Conclusions:

  • Increased postural instability during migraine attacks suggests transient cerebellar dysfunction.
  • Acute migraine episodes alter sensory processing, favoring reduced dependence on visual and proprioceptive information.
