Cerebral Hemispheres01:05

Cerebral Hemispheres

2.5K
The human brain, a complex organ, is functionally divided into two cerebral hemispheres—left and right. These hemispheres are interconnected by a structure of paramount importance, the corpus callosum. This substantial bundle of neural fibers is not just a bridge between the hemispheres but a crucial element for the brain's comprehensive functioning. It enables efficient communication between the two hemispheres, allowing each side of the brain to control and receive sensory and motor...

Lewis Acids and Bases02:33

Lewis Acids and Bases

48.5K
In 1923, G. N. Lewis proposed a generalized definition of acid-base behavior in which acids and bases are identified by their ability to accept or to donate a pair of electrons and form a coordinate covalent bond.
A coordinate covalent bond (or dative bond) occurs when one of the atoms in the bond provides both bonding electrons. For example, a coordinate covalent bond occurs when a water molecule combines with a hydrogen ion to form a hydronium ion. A coordinate covalent bond also results when...

Weak Base Solutions03:21

Weak Base Solutions

25.5K
Some compounds produce hydroxide ions when dissolved by chemically reacting with water molecules. In all cases, these compounds react only partially and so are classified as weak bases. These types of compounds are also abundant in nature and important commodities in various technologies. For example, global production of the weak base ammonia is typically well over 100 metric tons annually, being widely used as an agricultural fertilizer, a raw material for chemical synthesis of other...

Base Excision Repair01:54

Base Excision Repair

26.5K
One of the common DNA damages is the chemical alteration of single bases by alkylation, oxidation, or deamination. The altered bases cause mispairing and strand breakage during replication. This type of damage causes minimal change to the DNA double helix structure and can be repaired by the base excision repair (BER) pathways. BER corrects damaged DNA sequences by removing the damaged base and restoring the original base sequence using the complementary strand as a template.
The first step of...

Salts with Acidic Ions
Salts are ionic compounds composed of cations and anions, either of which may be capable of undergoing an acid or base ionization reaction with water. Aqueous salt solutions, therefore, may be acidic, basic, or neutral, depending on the relative acid-base strengths of the salt’s constituent ions. For example, dissolving the ammonium chloride in water results in its dissociation, as described by the equation:

Summary
This summary is machine-generated.

Upright angiography reveals significant changes in cerebral venous drainage, often rerouting through the paravertebral venous plexus when internal jugular veins collapse. This technique offers valuable insights into venous diseases.

Area of Science:

  • Neurology
  • Radiology
  • Vascular Medicine

Background:

  • Doppler ultrasound suggests cerebral venous drainage shifts to the paravertebral venous plexus in upright positions due to internal jugular vein collapse.
  • Previous studies indicate potential venous drainage alterations in an upright posture.

Purpose of the Study:

  • To present a novel venographic imaging technique during upright catheter-based angiography.
  • To provide additional diagnostic information for cerebral venous diseases.

Main Methods:

  • Acquisition of venographic images in both lying and upright (60°) positions using catheter-based angiography.
  • Utilized anteroposterior projection with radiolucent wedges to support patients in the upright position.

Main Results:

  • Observed activation of the paravertebral venous plexus as supplemental drainage in multiple patients.
  • Demonstrated exacerbation of internal jugular vein stenosis and relative collapse in the upright position.
  • Identified significant changes in venous drainage patterns, including attenuation and occlusion, in upright venography.

Conclusions:

  • Upright angiographic imaging reveals prominent alterations in cerebral venous drainage patterns.
  • Further research is needed to determine the clinical relevance of upright angiography findings in specific patient populations.
