Omentum: ‘Policeman of Abdomen’ is an Important Organ to be studied

The Omentum is the least familiar organ to the scientists as well as to the public.

  • The omentum is a large sheet of fat stretching protecting the stomach, intestines and the liver
  • The research published in the Journal ‘Trends in Immunology’ highlights that the immune organ is actually a nursery for cancer cells
  • Also called the ‘Policeman of Abdomen’, the omentum is central to our body’s immune system

June 06, 2017: 

What is the Omentum?

The omentum is like an apron shaped sheet of fat stretching from the liver, intestines to the stomach. White patches that are known as ‘milky spots’ cover the surface of the omentum. The milky spots gather information from cells, antigens, and bacteria in order to deduce what really is going on. Accordingly, the omentum decides what immune reaction is required by the abdomen. It fights against infections and toxins.

The Good Part:

The omentum is a doctor within your body. It takes reports of the status of your abdomen well-being and acts accordingly. Scientists believe that omentum may have answers on how to stop the rapid growth of aggressive tumors in the human body. The organ is now under scrutiny as most of the things about the omentum are still unknown.

The Bad Part: 

The omentum sometimes provides tolerance and not immunity to the tumor cells. Thus cancer cells are pushed towards the milky spots and they stick there. Cancer cells sometimes prompt a tolerant response from the omentum. Scientists fear that this fact of the omentum makes it a nursery for the breeding ground of more cancer cells. As the study says, omentum “sometimes makes wrong decisions”.

Scientists have announced a new finding about the source of a high-energy neutrino, a subatomic particle detected at an observatory at the Earth’s South Pole.

The study, published Thursday in the journal Science, details the work of more than 1,000 scientists who pooled their research on the tiny particles, which are able to pass through matter in a straight line — like a ghost.

The neutrino’s ability to travel without deviation from its course means its source can be accurately tracked, unlike other types of subatomic particles that can be dragged off course by a magnetic field like the Earth’s.

“[Neutrinos are] very clean, they have simple interactions, and that means every single neutrino interaction tells you something,” said Heidi Schellman, a particle physicist at Oregon State University.

The scientists used a large observatory known as IceCube, in use since 2010, to hunt for neutrinos and try to track the source. A group of neutrinos coming from the same location over the past couple of years was determined to have emanated from a blazar, or black hole that aims a jet of radiation at Earth. The black hole is estimated to have been in a distant galaxy that destructed four billion years ago.

The blazar that is considered the source of the neutrino was named TXS 0506+056 and is believed to be the first known source of a high-energy neutrino.

The discovery could be a breakthrough for multimessenger astronomy, where scientists look at the entire electromagnetic spectrum and pool their findings, using known relationships between types of electromagnetic particles to put together a larger picture.

“It is an entirely new means for us to learn about the cosmos,” Roopesh Ojha of NASA’s Goddard Space Flight Center told The Washington Post. (VOA)
