April 19: World Liver Day

The World Liver Day (WLD) is observed every year on April 19 to build awareness and understanding importance of liver in human body and how liver ailments can be treated. The 2018 theme for WLD is ‘Riding New Waves in Liver Diagnosis, Staging & Treatment’. As per World Health Organisation (WHO), liver diseases are 10th most common cause of death in India.

Liver

Liver is unique organ in human body and has special capacity of regeneration. It is the second largest organ and is key player in our body’s digestive system. Everything we consume passes through the liver. It fights infections, removes toxins, controls cholesterol, regulates blood sugar, make proteins and releases bile to help digestion. It has been seen that even 75% of liver can be safely removed without any untoward consequences because of its capacity of regeneration. Hence, to take care of the liver, one needs to adopt a healthy lifestyle and have a balanced diet of proteins, grains, dairy products, fruits, vegetables, and fats.

Scientist develop ingestible 3D-printed snake-like robot

Scientists have developed a tiny, ingestible 3D-printed snake-like robot called SAW (single actuator wave-like robot), that can navigate through the small intestines.

The snake-like tiny robot was made from a set of interlocking 3D-printed “plastic” pieces that look like vertebrae.

Key Facts
  • The robot moves in a wave-like motion and can travel through the extremely squishy environment of the small intestine.
  • The external shape of the robot is a 2D projection of a rotating helix, that result in a continuously moving wave. Its direction can be reversed simply by reversing the direction of rotation of the motor.
  • In tests, the robot was able to move incredibly fast and cross a wide array of terrains, from water to rough, rocky soil.
  • Potential application: It can be used to visualise the digestive system in real time, especially for colonoscopies.
