Pathophysiology of Vomiting01:22

Pathophysiology of Vomiting

2.5K
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

Transmission-based Precautions I: Contact, Enteric, and Droplets

4.4K
Transmission-based precautions are for patients known to be infected or suspected to be infected or colonized with organisms that pose a significant risk to others. Some transmission-based precautions include contact, enteric, and droplet.
Contact Precautions:
Contact precautions are the measures taken to prevent the transmission of infectious agents, especially epidemiologically important microorganisms such as MRSA or influenza, primarily transmitted through direct or indirect contact with an...

Blood Transfusion and Agglutination

13.9K
Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Development of Immunocompetence

726
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...

Animal Mitochondrial Genetics02:59

Animal Mitochondrial Genetics

8.9K
Among all the organelles in an animal cell, only mitochondria have their own independent genomes. Animal mitochondrial DNA is a double-stranded, closed-circular molecule with around 20,000 base pairs. Mitochondrial DNA is unique in that one of its two strands, the heavy, or H, -strand is guanine rich, whereas the complementary strand is cytosine rich and called the light, or L, -strand. Compared to nuclear DNA, mitochondrial DNA has a very low percentage of non-coding regions and is marked by...

Summary

Vomocytosis, a process where pathogens like Cryptococcus neoformans are expelled by host cells, is increasingly understood. However, the exact mechanisms and disease impact of this nonlytic exocytosis remain key research questions.

Area of Science:

  • Microbiology
  • Immunology
  • Cell Biology

Background:

  • Vomocytosis, or nonlytic exocytosis, is a cellular process involving the expulsion of pathogens.
  • First reported for Cryptococcus neoformans in 2006, the phenomenon has since been observed with other pathogens and host cells.

Purpose of the Study:

  • To summarize current findings on vomocytosis.
  • To highlight unresolved questions regarding the mechanisms and implications of vomocytosis in disease.

Main Methods:

  • Literature review of studies on vomocytosis.
  • Analysis of reported molecular components and cellular interactions involved in vomocytosis.

Main Results:

  • The number of known vomocytosing pathogens and host cells has expanded.
  • Various molecular factors associated with vomocytosis have been identified.

Conclusions:

  • Despite advances, the precise trigger (host or pathogen) for vomocytosis is unknown.
  • The impact of vomocytosis on disease progression requires further investigation.
