Antibody Structure01:10

Antibody Structure

65.4K
Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Reproductive Cloning01:27

Reproductive Cloning

32.6K
Reproductive cloning is the process of producing a genetically identical copy—a clone—of an entire organism. While clones can be produced by splitting an early embryo—similar to what happens naturally with identical twins—cloning of adult animals is usually done by a process called somatic cell nuclear transfer (SCNT).
Somatic Cell Nuclear Transfer
In SCNT, an egg cell is taken from an animal and its nucleus is removed, creating an enucleated egg. Then a somatic...

X-Inactivation01:58

X-Inactivation

41.7K
The human X chromosome contains over ten times the number of genes as in the Y chromosome. Since males have only one X chromosome, and females have two, one might expect females to produce twice as many of the proteins, with undesirable results.

Hair Cells01:22

Hair Cells

44.6K
Hair cells are the sensory receptors of the auditory system—they transduce mechanical sound waves into electrical energy that the nervous system can understand. Hair cells are located in the organ of Corti within the cochlea of the inner ear, between the basilar and tectorial membranes. The actual sensory receptors are called inner hair cells. The outer hair cells serve other functions, such as sound amplification in the cochlea, and are not discussed in detail here.

Conservation of Small Populations02:04

Conservation of Small Populations

16.7K
Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...

Summary

This is the first reported case of feline cholesteatoma, a cyst-like mass originating from the middle ear. This diagnosis should be considered for cats with oropharyngeal masses or ear disease history.

Area of Science:

  • Veterinary Medicine
  • Otolaryngology
  • Pathology

Background:

  • Cholesteatoma, a benign epithelial growth, is common in human middle ear disease but rarely reported in felines.
  • Oropharyngeal masses in cats can stem from various causes, necessitating accurate diagnosis.

Observation:

  • A 14-year-old Burmese cat presented with a caudal oropharyngeal mass.
  • Computed Tomography (CT) revealed a cystic structure expanding from the right tympanic bulla.
  • Histopathology confirmed the presence of squamous epithelium and keratin, consistent with cholesteatoma.

Findings:

  • The study documents the first confirmed case of feline cholesteatoma.
  • The mass was characterized as a thin-walled, cyst-like structure involving the tympanic bulla.
  • Histopathological analysis revealed characteristic features of cholesteatoma.

Implications:

  • Feline cholesteatoma should be included in the differential diagnosis for oropharyngeal masses in cats.
  • Consideration for cholesteatoma is particularly relevant in cats with chronic or surgically managed ear disease.
  • Advanced imaging (CT) and biopsies are crucial for diagnosing feline cholesteatoma.
