Introduction to Medical Biotechnology

Introduction

  • Medical biotechnology is a field of science that combines biology, medicine, and technology to develop tools, treatments, and therapies that improve human health. 
  • By harnessing the principles of biology and the power of cutting-edge technology, medical biotechnology aims to solve complex health problems, from infectious diseases to cancer and genetic disorders.

Key Areas in Medical Biotechnology

  • Drug Development:

    • Designing and producing pharmaceutical drugs using biological systems.
    • Biopharmaceuticals, like insulin and monoclonal antibodies, are prime examples.

  • Gene Therapy:

    • Introducing, removing, or altering genetic material in cells to treat or prevent diseases.
    • Used in treating genetic disorders like muscular dystrophy and haemophilia.

  • Tissue Engineering:

    • Developing artificial organs or tissues for transplant or therapeutic purposes.
    • Involves stem cell research to regenerate damaged tissues.

  • Diagnostic Tools:

    • Creation of advanced diagnostic methods like PCR and DNA sequencing for early disease detection.
    • Biotechnology is crucial for personalized medicine and precision diagnostics.

Scopes of Medical Biotechnology

  • Pharmaceutical Industry:
    • Development of novel drugs and vaccines.
    • Biopharmaceuticals, which include protein-based drugs like insulin, growth factors, and monoclonal antibodies.
    • Genetic engineering for the production of safer, more effective medications.
  • Regenerative Medicine:
    • Stem cell therapy and tissue engineering, aiming to repair or replace damaged tissues and organs.
    • Growing artificial tissues and organs in the lab to be used in transplants and surgeries.
    • Helping in the treatment of spinal cord injuries, diabetes, heart diseases, and more.
  • Diagnostics and Genetic Testing:
    • Genetic tests for disease risk assessment, prenatal diagnosis, and personalized medicine.
    • Advanced diagnostic tools that enable early detection of diseases, such as cancer biomarkers and pathogen detection.
    • Techniques like CRISPR and next-generation sequencing (NGS) improve precision in disease detection.
  • Agriculture and Healthcare Interface:
    • Use of biotechnology in producing genetically modified organisms (GMOs) to improve nutrition and health outcomes.
    • Biopharmaceuticals derived from plants, including edible vaccines and therapeutic proteins.
  • Infectious Disease Control:
    • Vaccine development and the creation of antiviral therapies using biotechnology.
    • Production of immunotherapies to boost the immune system's response to infectious agents.
    • Tools to rapidly detect, diagnose, and monitor outbreaks of diseases like COVID-19, malaria, and tuberculosis.
  • Research and Academia:
    • Biotechnology research offers insights into disease mechanisms and potential treatments.
    • Opportunities for careers in academic and industrial research focused on drug discovery, cell biology, and molecular biology.

Charter of Queen Elizabeth I & the East India Company

  Charter of Queen Elizabeth I & the East India Company   Background Francis Drake’s Voyage (1580) : First Englishman to sail around the world, inspiring exploration. Defeat of Spanish Armada (1588) : England’s naval victory boosted confidence to challenge Spain/Portugal in global trade. Portuguese & Dutch Profits : Europeans made huge money from Asian spices, textiles, and goods → England wanted a share! Formation of the East India Company 1599 : Group of English merchants ( Merchant Adventurers ) formed a company to trade in Asia. 31 December 1600 :  Queen Elizabeth I  granted them a  Royal Charter , giving: Exclusive Rights : Only this company could trade east of Africa (monopoly). Name : “Governor and Company of Merchants of London trading into the East Indies” (later called  East India Company ). 1609 : Monopoly extended  indefi...
