Helicobacter pylori : Study

The National Institute of Cholera and Enteric Diseases has made quick detection of drug-resistant ‘Helicobacter pylori possible recently.

  • A two-step PCR-based assay of a small region of the Helicobacter pylori (H. pylori) bacteria can help detect H. pylori infection and also identify clarithromycin-resistant bacteria and those that are drug-sensitive in six-seven hours has been developed by a team of researchers from the National Institute of Cholera and Enteric Diseases (ICMR-NICED), Kolkata.

Helicobacter pylori:-

  • It is a bacterium that infects the stomach lining.
  • It is linked to gastrointestinal issues like peptic ulcers and stomach cancer.
  • About two-thirds of the world’s population has it in their bodies.
  • For most people, it never causes any symptoms.
  • In India, H. pylori infection affects 60-70% of the population.
  • This usually happens during childhood and remains in the stomach throughout their life if not treated with antibiotics effectively.
  • Symptoms:
    • An ache or burning pain in your stomach (abdomen)
    • Stomach pain that may be worse when your stomach is empty
  • Treatment:-

Global Positioning System Tracker Anklet:

A prisoner in Jammu and Kashmir was released on bail after he was tagged with a Global Positioning System (GPS) tracker anklet on his foot to monitor his movements.

  • This is the first time in the country that a GPS tracker has been put to such use.
  • GPS anklets are small, wearable devices that are attached to the ankles of individuals who are under some form of legal supervision, such as parole, probation, house arrest, or bail.
  • The tracker can be put on the ankle or arm of a person.
  • Thus, there are GPS anklets and GPS bracelets.
  • GPS anklets are tamper-proof, and any attempt to remove or damage them triggers an alarm.
  • They also have a battery life of several days and can be recharged by the wearer.
  • GPS anklets can also be used to enforce curfews, travel restrictions, or other conditions imposed by the court or the supervising agency.

Picocystis Salinarum: Green Algae

A young researcher has divulged the secret of how the Picocystis Salinarum survives the harshest of conditions by resorting to physiological adaptation to highly saline-alkaline/hyperosmotic conditions.

  • Picocystis Salinarum is a globally widespread picoplanktonic green algae of saline lakes.
  • It is one of the smallest green algae.
  • It is found in hypersaline soda lake Sambhar, Rajasthan, to survive extreme environments.
  • Though the algae had been widely found in saline-soda lakes around the world, it was spotted for the first time in India only in the Sambhar Lake.
  • The unique organism apparently enhances photosynthesis and ATP synthesis along with chaperone proteins as key response to high salinity-alkalinity.
  • Enhanced photosynthetic activity exhibited by P. salinarum in highly saline-alkaline condition is noteworthy as photosynthesis is suppressed under hyperosmotic conditions in most photosynthetic organisms.
