Lampbrush Chromosomes01:51

Lampbrush Chromosomes

8.7K
In 1882, Flemming observed lampbrush chromosomes (LBC) in salamander eggs. Later in 1892, Rückert observed LBCs in shark egg cells and coined the term "lampbrush chromosomes" because they looked like brushes used to clean kerosene lamps.
LBCs are made up of two pairs of conjugating homologous chromatids. Each chromatid consists of alternatively positioned regions of condensed-inactive chromatin and loosely placed-active side loops, which can be contracted and extended. The loops...

Polytene Chromosomes

11.0K
Polytene chromosomes are giant interphase chromosomes with several DNA strands placed side by side. They were discovered in the year 1881 by Balbiani in salivary glands, intestine, muscles, malpighian tubules, and hypoderm of larvae Chironomus plumosus. Hence, these are also called "Salivary gland chromosomes." These are found in insects of the order Diptera and Collembola; in certain organs of mammals; and synergids, antipodes of flowering plants. Polytene chromosomes are also...

Light Acquisition02:16

Light Acquisition

9.6K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

Summary
This summary is machine-generated.

Large tonsillar stones, though rare, can cause persistent sore throats and snoring. This case highlights a 3.1 × 2.3 cm tonsillar stone successfully removed with tonsillectomy.

Area of Science:

  • Otolaryngology
  • Oral and Maxillofacial Surgery

Background:

  • Tonsillar stones (tonsilloliths) are calcified debris in palatine tonsil crypts, commonly causing halitosis.
  • While frequent, extremely large tonsillar stones are exceptionally rare clinical findings.

Observation:

  • A 45-year-old male presented with chronic sore throat, recurrent tonsillitis, and snoring.
  • Physical examination revealed unremarkable ears, nose, and throat findings, except for a significantly large tonsillar stone in the left palatine tonsil.

Findings:

  • Imaging confirmed a large tonsillar stone measuring 3.1 × 2.3 cm.
  • The patient underwent successful surgical removal of the tonsillar stone and a tonsillectomy.

Implications:

  • This case underscores the possibility of massive tonsillar stone development, even without typical preceding symptoms.
  • Surgical intervention, including tonsillectomy, is an effective treatment for large, symptomatic tonsillar stones.
