Smallest Air Pollution Can Trigger Lung Cancer-Study Reveals

Air Pollution

Scientists have found the first link to how small air pollution can precipitate lung cancer. The effects of air pollution on your respiratory system can vary according to the components and the concentration of the pollutants. Fine particulate matter (FPM), which is the smallest inhalable particle present in air pollution has been indicted as a Group I carcinogen and a major health risk.

Zhenzhen Wang, an associate researcher at Nanjing University (NJU) in Nanjing, China in partnership with labs at NJU and the University of Macau gathered FPM from seven different locations in China. The team evaluated the effects of FPM on cytotoxic T-cells, which are the key immune cells that fight tumor development (CTLs). It was seen that the subjects of the experiment (Mice) who were exposed to FPM had very poor T cell proliferation and the growth of tumors happened unhindered. However, in the group which was not exposed to FPM, there was a rapid proliferation of the T cells which quickly annihilated the tumor cells and their development was stopped.

The Effects Of Air Pollution On Your Lungs

Higher pollutant levels have more lethal effects on people who have respiratory ailments such as asthma. The severity of the symptoms are increased manyfold if the person is inhaling highly polluted air.  Asthmatic patients need to use their reliever inhaler more frequently than usual. It’s also critical that you use your preventer inhaler on a regular basis.

There is strong evidence that outdoor air pollution causes lung cancer. Prolonged exposure to high air pollution levels can also cause asthma, bronchitis, and even emphysema.  Air pollution also has a debilitating effect on the development of lung tissues in growing children.

Latest data also suggests that kids who grow up in polluted environments are more likely to develop asthma.

IIT-K and BFI forge partnership to accelerate healthcare innovation in India

Kanpur, April 17 (IANS) – The Indian Institute of Technology Kanpur (IIT-K) has entered into a strategic partnership with Blockchain For Impact (BFI) to drive advancements in healthcare in India. Under the BFI-Biome Virtual Network Programme, this collaboration aims to nurture innovations in the healthcare sector.

As part of the partnership, BFI will support IIT Kanpur in promoting entrepreneurial initiatives through the Startup Incubation & Innovation Centre (SIIC). A Memorandum of Understanding (MoU) was signed at IIT Kanpur by Prof. Kantesh Balani, Dean of Resources and Alumni (DoRA), IIT Kanpur; and Dr. Gaurav Singh, CEO BFI.

BFI has committed to allocating over $150,000 across three years to develop programmes tailored to healthcare-focused startups at IIT Kanpur’s SIIC. This collaboration harnesses IIT Kanpur’s expertise in fostering entrepreneurship and BFI’s dedication to advancing biomedical research.

Prof. Kantesh Balani, DoRA, IIT Kanpur, expressed his optimism about the partnership, stating, “This MoU will help us share knowledge, support startups effectively, and improve our capacity-building efforts.” Dr. Gaurav Singh, CEO of BFI, highlighted the inspiring work of IIT Kanpur incubatees in healthcare innovation and the alignment of missions to accelerate impactful solutions in biomedical research.

This partnership signifies a significant step towards advancing healthcare innovation in India by leveraging expertise and resources. The collaboration between IITK and BFI holds promise for improving public health and ensuring equitable healthcare access for all.

Doctors are hopeful that gene therapy could be a breakthrough for haemophilia, a blood disorder

Gene therapy holds promise for blood disorder haemophilia: Doctors

On World Haemophilia Day, doctors highlighted the potential of gene therapy in treating haemophilia, a hereditary blood disorder. Haemophilia is caused by missing or defective clotting factors and raises the risk of severe bleeding and joint damage. Genetic counselling and screening are crucial for affected individuals. India has a high number of haemophilia cases, but many go undiagnosed due to lack of screening capabilities.

Gene therapy offers a promising approach to treating haemophilia by delivering functional genes to correct the genetic defect responsible for deficient clotting factor production. Recent clinical trials show positive outcomes, including the use of lentiviral vectors at CMC Vellore. While current treatment involves factor VIII infusions, gene therapy may offer a cure for haemophilia, especially in low and middle-income countries.

According to Anoop P, Sr. Consultant – Haematology at Aster RV Hospital, “Gene therapy is a potentially curative treatment for haemophilia.” It allows for editing the faulty gene of a baby inside the uterus, known to be born with haemophilia due to a family history. Ongoing research on gene therapy shows promising results, indicating a potential paradigm shift in the management and cure of haemophilia.

How daytime sleep can raise dementia risk

New Delhi, April 17 (IANS) Compensating for lack of sleep during the daytime may not be as effective as previously thought, warned Dr. Sudhir Kumar, a neurologist based in Hyderabad. According to Dr. Sudhir, daytime sleep is not in sync with the body’s natural clock and can increase the risk of dementia and other psychiatric disorders.

Dr. Sudhir, from Indraprastha Apollo Hospitals, highlighted in a post on X.com that daytime sleep is lighter and does not fulfill the body’s sleep requirements. He explained, “This fact is supported by numerous studies of night shift workers, who are predisposed to stress, obesity, cognitive deficits, and an elevated risk of neurodegenerative diseases.”

The neurologist pointed out that the glymphatic system, responsible for clearing the brain of protein waste products, is most active during sleep. Therefore, when there is a lack of sleep, the glymphatic system may fail, increasing the risk of dementia. Dr. Sudhir stated, “Glymphatic failure is the common pathway of dementia, leading to the accumulation of abnormal proteins in the brain.”

Factors such as poor sleep quality, age, sedentary lifestyle, cardiovascular diseases, obesity, sleep apnoea, circadian misalignment, substance abuse, and depression can also suppress or result in the failure of the glymphatic system. Dr. Sudhir emphasized, “Good sleepers tend to live longer, weigh less, have a reduced incidence of psychiatric disorders, and maintain cognitive function for longer periods.”

In conclusion, Dr. Sudhir advised that consistently sleeping well at night can lead to better cognitive function and decrease the risk of dementia and psychiatric disorders. It is essential to prioritize quality sleep to maintain overall brain health and reduce the risk of neurodegenerative diseases.
