Sjogren’s Disease Latest News

Researchers from Japan recently discovered a self-reinforcing loop between different immune cells that sustains autoimmune responses in patients with Sjögren's disease.

About Sjogren’s Disease

  • Sjögren's disease (also called Sjögren’s syndrome) is a chronic autoimmune disorder where the immune system mistakenly attacks its own moisture-producing glands.
  • It typically attacks the glands that produce tears, saliva, and sweat. Other parts of the body may also be affected. 

Sjogren’s Disease Cause

  • The exact cause of Sjögren's syndrome is unknown, though there seems to be a genetic influence. 
  • It is thought that factors such as viral infections, stress, and hormone changes can trigger symptoms of Sjögren's syndrome. 
  • Sjogren syndrome can happen at any age. But most people are older than 40 at the time of diagnosis. 
  • Ninety percent (90%) of adults diagnosed with Sjögren’s are women.
  • Sjogren’s can occur alone or in association with other autoimmune diseases, most commonly lupus and rheumatoid arthritis (RA). 

Sjogren’s Disease Symptoms 

  • People with Sjögren's syndrome can have:
    • dry eyes, which may also feel painful, burning, itchy, or gritty
    • a dry mouth, making it difficult to swallow, speak, or eat dry foods
    • swelling of the glands in the face and neck areas
  • Some people with Sjögren's syndrome also notice:
    • joint pain, swelling and stiffness
    • dry skin or skin rash
    • vaginal dryness
    • persistent dry cough
    • ongoing fatigue
  • Sometimes the liver and kidneys are affected. A few people will also develop lymphoma (cancer of the lymph nodes). 

Sjogren’s Disease Treatment 

  • There is no cure for Sjögren's syndrome. 
  • Treatment for Sjogren’s disease attempts to relieve the effects of chronic dryness of the mouth and eyes by increasing the lubrication and moisturization of the affected tissues.

Angkor Thom

Angkor Thom Latest News

Archaeologists recently uncovered significant remains of a 12th-century hydraulic system and architectural features within the ancient royal palace complex of Angkor Thom.

About Angkor Thom

  • Angkor Thom, located in present-day Cambodia, was the last and longest-lasting capital of the ancient Khmer Empire. 
  • Angkor Thom translates into English as the “Great City”.

Angkor Thom History

    • It was established after Jayavarman VII reclaimed the Khmer capital from the Cham invaders in 1181. 
    • Unlike earlier Hindu temples, Angkor Thom was designed as a Buddhist city, reflecting the king’s devotion to Mahayana Buddhism. 
    • However, it also incorporated elements of Hinduism and ancestral worship, showcasing the empire’s religious syncretism. 
    • Angkor Thom witnessed the reign of the greatest Angkor king until 1219 and remained the capital of the Khmer Empire throughout its decline, which probably led to the complete abandonment in the 16th century. 

Angkor Thom Features

  • It covers an area of 9 km, within which are located several monuments from earlier eras as well as those established by Jayavarman and his successors. 
  • It is a square-shaped city with walls approximately 8 metres high and about 3 kilometres long on each side.

  • Bayon Temple: At its centre stands the famous Bayon, renowned for its numerous giant stone faces. 
  • Other Important Structures:
    • Terrace of the Elephants
    • Terrace of the Leper King
    • Baphuon

Doctrine Of Forum Non Conveniens

Doctrine Of Forum Non Conveniens

Doctrine Of Forum Non Conveniens Latest News

The Supreme Court recently held that where the question of pursuing a constitutional remedy is involved, and invocation of writ jurisdiction is traceable to clause (1) of Article 226, the doctrine of forum non conveniens may rarely apply.

About Doctrine Of Forum Non Conveniens

  • It is a common law legal principle that allows a court to dismiss or stay a case when it believes that another forum is more appropriate for hearing the case, even if the court itself has jurisdiction over the case and the parties. 
  • The term “forum non conveniens” is Latin for “inconvenient forum,” and the doctrine has been applied in various legal systems, particularly those with roots in English common law.  
  • This doctrine plays a critical role in private international law (conflict of laws), where courts frequently deal with cross-border disputes that involve multiple jurisdictions. 
  • The application of the doctrine is typically discretionary, meaning that trial courts have significant latitude in deciding whether to dismiss or stay a case based on this principle. 
  • Courts are required to balance several factors in determining whether to apply the doctrine, including both private and public interests. 
    • Courts consider various factors, including the convenience of the parties, the location of evidence and witnesses, the applicable law, and the availability of a fair trial in the alternative forum. 
    • The overriding consideration is whether the interests of justice would be better served by litigating the matter in another jurisdiction. 
  • Generally, the doctrine is invoked by defendants who argue that the current forum is inappropriate and that a different jurisdiction would be more suitable for the case. 
  • The defendant must demonstrate that an alternative forum exists where the case can be adequately heard. 
  • This forum must have jurisdiction over the parties and the subject matter of the case and must provide the plaintiff with an adequate remedy.
