πŸ”† First-Ever Gene Therapy for Genetic Hearing Loss

πŸ“ Why in News?
βœ… The United States Food and Drug Administration has approved the first gene therapy for genetic hearing lossβ€”Otarmeni, developed by Regeneron Pharmaceuticals.

πŸ“ Key Highlights of the Therapy

β–ͺ️ Target: OTOF Gene Mutation
βœ… The OTOF produces otoferlin, essential for converting sound vibrations into neural signals.
❌ Defective copies lead to severe-to-profound hearing loss (2–8% of inherited cases).

β–ͺ️ How Otarmeni Works
βœ… A one-time biologic-device combination therapy.
βœ… Uses dual AAV (Adeno-Associated Virus) vectors to deliver a functional gene.
βœ… Restores otoferlin production in inner ear hair cells.
βœ… Enables proper auditory signal transmission to the brain.

πŸ“ What is Gene Therapy?

β–ͺ️ Gene therapy involves inserting or modifying genes to treat diseases.
β–ͺ️ Uses vectors (commonly viruses) to deliver therapeutic genes into target cells.
β–ͺ️ It targets the root genetic cause rather than symptoms.

πŸ“ Significance

βœ… First approved gene therapy for hearing loss
βœ… Potential cure for inherited deafness
βœ… One-time treatment vs lifelong management
βœ… Opens new avenues for treating genetic disorders

πŸ“ Concerns

β–ͺ️ High cost and accessibility issues
β–ͺ️ Long-term safety and durability yet to be fully assessed

πŸ“ Conclusion
Gene therapy like Otarmeni marks a breakthrough in precision medicine, shifting healthcare from symptom management to genetic correction.

πŸ”† How far is it correct to say that the First World War was fought essentially for the preservation of balance of power? (250 words)

πŸ“ Introduction
First World War was fought between the Allied and Central Powers. While preservation of balance of power was a key factor, it alone cannot fully explain the outbreak.

πŸ“ Balance of Power as a Cause

β–ͺ️ Alliance System
βœ… Triple Entente aimed to counterbalance
Triple Alliance.

β–ͺ️ Germany’s Rise
βœ… Rapid industrial and military expansion of Germany disturbed European equilibrium, alarming Britain and France.

β–ͺ️ Fear of Dominance
βœ… Powers sought to prevent any single nation from achieving hegemony in Europe.

πŸ“ Other Contributing Factors

β–ͺ️ Imperialism
βœ… Rivalry over colonies in Africa and Asia intensified tensions.

β–ͺ️ Militarism
βœ… Arms race and glorification of military power increased war preparedness.

β–ͺ️ Nationalism
βœ… Ethnic tensions in the Balkans, especially Slavic nationalism, destabilised Europe.

β–ͺ️ Immediate Trigger
βœ… Assassination of Archduke Franz Ferdinand in 1914 escalated into war.

πŸ“ Evaluation
While balance of power politics created a fragile environment, deeper structural causes like nationalism, imperial rivalry and militarism made war inevitable. The alliance system converted a regional conflict into a global war.

πŸ“ Conclusion
Thus, the war was partly about preserving balance of power, but it was equally driven by broader political, economic and ideological factors.
