Lobes of the Cerebrum01:22

Lobes of the Cerebrum

4.3K
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements....

Base Excision Repair01:54

Base Excision Repair

26.1K
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...

Lewis Acids and Bases

48.2K
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 Solutions

24.9K
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...

Ions as Acids and Bases

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

Supratentorial hemangioblastomas are rare but can occur without von Hippel-Lindau disease. Surgical resection is the definitive treatment, and regular follow-up is essential for patients.

Area of Science:

  • Neurology
  • Neurosurgery
  • Pathology

Background:

  • Hemangioblastomas are rare benign vascular neoplasms, typically associated with von Hippel-Lindau disease.
  • They predominantly affect men around 36 years old and rarely occur in the supratentorial region.
  • Diagnostic challenges arise due to rarity and differential diagnoses with other supratentorial neoplasms.

Observation:

  • A 64-year-old woman presented with seizures due to a frontal supratentorial hemangioblastoma.
  • Initial imaging suggested a meningioma due to extra-axial location and dural tail sign, complicating diagnosis.

Findings:

  • Microneurosurgery achieved complete tumor resection, with histopathology confirming hemangioblastoma.
  • The patient experienced clinical improvement and no recurrence over a 2-year follow-up.

Implications:

  • Supratentorial meningeal hemangioblastomas can occur in patients without von Hippel-Lindau disease.
  • Surgical resection is the definitive treatment, and regular follow-up is essential for these rare neoplasms.
