• Prelims –SCIENCE AND TECHNOLOGY

Context: Recently, Brazil scientists developed a new ‘vaccine’ Calixcoca” Vaccine, for cocaine addiction.

About“Calixcoca” Vaccine:-

• Calixcoca’, is a therapeutic vaccine that promises to prevent the addictive effects of cocaine or crack.( Drug Addiction)
• It is offering new hope to millions battling cocaine addiction worldwide. (mRNA Vaccine)

Working:-

• Calixcoca functions by inducing an immune response that generates antibodies capable of binding to cocaine molecules in the bloodstream.
• This binding process results in the enlargement of cocaine molecules, rendering them too large to pass into the brain’s “reward centre” or mesolimbic system.
• This area of the brain is typically stimulated by cocaine to release dopamine, the pleasure-inducing neurotransmitter.
• Consequently, individuals who receive the vaccine will not experience the desired euphoric effects of cocaine, potentially assisting them in breaking the cycle of addiction.
• Furthermore, it reduces the risk of overdose as cocaine molecules are retained in the blood, bound to the antibodies, and thus, unable to act on the heart or arteries.
• Following encouraging results in animal trials, Calixcoca is poised to enter the next phase of development, which involves human trials.
• Calixcoca is designed for recovering addicts who have already discontinued cocaine use and are seeking assistance in maintaining their sobriety.

Significance:-

• Despite the alarming rise in cocaine and crack addiction, there are no approved medications specifically for treating this problem.
• The development of the Calixcoca vaccine, therefore, is a beacon of hope for an effective medical intervention.

Context: A child was diagnosed with the rarest of rare diseases Infantile Hypophosphatasia in India recently.

Background:-

• 16-month-old Sera Nile Fay is India’s only known case of Infantile Hypophosphatasia.

About Infantile Hypophosphatasia:-

• It is a rare genetic disease. (Rare Disease)
• In which the patient’s bones and teeth demineralize, making her fragile and prone to fractures.
• It is caused by mutations in the ALPL gene.
• This is the only gene that causes HPP.
• Genes provide instructions for making proteins that have an important function in the body.
• When a mutation occurs, the protein may be faulty, inefficient, or absent, as in HPP.

Symptoms:-

• It may have no noticeable abnormalities at birth, but complications become apparent within the first six months of life.
• Sometimes the skull bones fuse, called craniosynostosis, which can lead to a deformed head.
• Affected infants have softened, weakened, and deformed bones consistent with rickets.

Treatment:-

• Asfotase alfa is approved (Europe and USA) for enzyme replacement therapy (ERT) in patients with pediatric-onset hypophosphatasia.
• It is associated with healing of the skeletal manifestations of hypophosphatasia as well as improved respiratory and motor function.

As per the data released by the Central Pollution Control Board (CPCB) in Delhi, the air quality was in the ‘moderate’ category in several areas. Meanwhile, for past few days, the AQI of the financial capital of India remained ‘poor’, according to System of Air Quality and Weather Forecasting and Research (Safar). Air pollution in India has reached critical levels, posing severe threats to human health and the environment.

PRIMARY CAUSESOF AIR POLLUTION IN INDIA

• Vehicular Emissions: Vehicles are one of the major sources of air pollution in India, especially in urban areas. According to a study by the Centre for Science and Environment (CSE), vehicles contribute to 40% of PM2.5 emissions in Delhi, 30% in Mumbai, 28% in Kolkata, and 20% in Bengaluru.
• Industrial Chimney Wastes: Industries are another major contributor to air pollution in India, especially in the northern and eastern regions. These plants emitted sulfur dioxide, nitrogen oxides, carbon monoxide, lead, mercury, and VOCs, which can cause acid rain, smog, climate change, and health problems.
• Burning Fossil Fuels: Power plants, factories, and households that use coal, oil, or natural gas as fuel also contribute to air pollution in India by emitting greenhouse gasses. According to the World Bank Group, India is the third-largest emitter of CO2 in the world, after China and the United States.
• Agricultural Activities: Farming practices such as burning crop residues, using fertilizers and pesticides, and raising livestock also produce air pollution in India. According to a study by the IIT Delhi, crop burning contributed to 44% of Delhi’s PM2.5 concentration during the peak pollution season in November 2019.
• Burning of Garbage Waste: Many people in India dispose of their household waste by burning it in open spaces. This practice releases toxic chemicals and dioxins into the air, which can cause cancer and other diseases. According to a study by The Energy and Resources Institute (TERI), waste burning contributed to 29% of Delhi’s PM10 concentration during the winter season in 2018.

CHALLENGES IN ADDRESSING AIR POLLUTION

• Diverse Sources: Air pollution originates from a wide range of sources, including industrial activities, transportation, agriculture, energy production, and natural sources. Coordinating efforts to control and reduce pollution from these diverse sources can be challenging.
• Urbanization: Rapid urbanization in many parts of the world has led to increased vehicular traffic, industrial activities, and energy consumption, resulting in concentrated sources of air pollution in urban areas.
• Industrial Growth: Developing economies often experience rapid industrial growth, which can lead to increased emissions of pollutants. Balancing economic development with pollution control is a delicate challenge.
• Energy Production: The reliance on fossil fuels for energy production is a significant contributor to air pollution. Transitioning to cleaner and more sustainable energy sources presents challenges in terms of infrastructure and policy changes.
• International Cooperation: Air pollution knows no boundaries, and pollutants can travel across borders. Effective cooperation between countries is necessary to address transboundary pollution and to reduce the global impact of air pollution.
• Technological Challenges: Developing and implementing advanced pollution control technologies can be costly and technically challenging, especially for older industries and infrastructure.
• Public Awareness and Behavior: Encouraging individuals to adopt cleaner practices, such as reducing vehicle emissions or using energy-efficient appliances, can be difficult. Public awareness and behavior change campaigns are needed.

CONCLUSION

The battle against air pollution in India is not just about improving the air quality we breathe, it is a fight for public health, environmental sustainability, and the well-being of future generations. Collaboration at local, national, and international levels is essential to make meaningful progress in reducing air pollution and its associated health and environmental impacts.
