In a novel initiative, about 20,000 students of Chennai Corporation-run schools have turned health ambassadors and appealed to the people to maintain cleanliness in their houses and streets, said a statement on Friday.

The campaign is for preventing the spread of monsoon related diseases.

The Chennai Corporation has also released a video film featuring student ambassadors as part of its awareness campaign “Clean Chennai, Healthy Chennai.”

The student health ambassadors were selected from various educational institutions across the city last month.

Tamil Nadu Minister for Municipal Administration S.P.Velumani, had met the student ambassadors, congratulated them and gave them their identity cards.

He requested the student ambassadors to create awareness about cleanliness, sanitation and about dengue and other contagious diseases in their neighbourhood.

An audio-visual presentation made by Chennai Corporation, featuring the student ambassadors was released.

The campaign began with a “Clean homes, clean streets” message, and stressed the need for self-motivation to keep homes and the neighbourhood clean, and requested the cooperation of the audience to combat the dengue mosquitoes.

The Chennai Corporation also plans to run awareness campaigns via auto-rickshaws in fifteen zones during weekends on diseases that occur during the monsoon and the preventive steps that need to be taken.

Rallies are also planned in all the 15 zones, with the participation of 20,000 city school students, to spread awareness about prevention of mosquito-borne diseases during monsoon, stopping open defecation, stopping usage of plastic, preventing stagnation of sewage or clean water and rainwater harvesting.

On behalf of Chennai Corporation, it was announced that the students will take out rallies near their schools and distribute pamphlets and flyers with these messages. (IANS)

Immune Cells Become Active and Repair Brain While Sleep: Study

For the findings, researchers conducted the study on mice

Study suggests that the enhanced remodeling of neural circuits and repair of lesions during Sleep may be mediated in part by the ability of microglia to dynamically interact with the Brain. Pixabay

Researchers have found that immune cells called microglia, which play an important role in reorganising the connections between nerve cells, fighting infections, and repairing damage, are also primarily active while we sleep.

Microglia serve as the brain’s first responders, patrolling the brain and spinal cord and springing into action to stamp out infections or gobble up debris from dead cell tissue.

“This research shows that the signals in our brain that modulate the sleep and awake state also act as a switch that turns the immune system off and on,” said study lead author Ania Majewska, Professor at University of Rochester in the US.

In previous studies, Majewska’s lab has shown how microglia interact with synapses, the juncture where the axons of one neuron connects and communicates with its neighbours.

The microglia help maintain the health and function of the synapses and prune connections between nerve cells when they are no longer necessary for brain function.

For the findings, researchers conducted the study on mice.

The current study points to the role of norepinephrine, a neurotransmitter that signals arousal and stress in the central nervous system.

This chemical is present in low levels in the brain while we sleep, but when production ramps up it arouses our nerve cells, causing us to wake up and become alert.

The study showed that norepinephrine also acts on a specific receptor, the beta2 adrenergic receptor, which is expressed at high levels in microglia.

When this chemical is present in the brain, the microglia slip into a sort of hibernation.

The study, which employed an advanced imaging technology that allows researchers to observe activity in the living brain, showed that when mice were exposed to high levels of norepinephrine, the microglia became inactive and were unable to respond to local injuries and pulled back from their role in rewiring brain networks.

“This work suggests that the enhanced remodeling of neural circuits and repair of lesions during sleep may be mediated in part by the ability of microglia to dynamically interact with the brain,” said study first author Rianne Stowell.

“Altogether, this research also shows that microglia are exquisitely sensitive to signals that modulate brain function and that microglial dynamics and functions are modulated by the behavioural state of the animal,” Stowell said.

The study was published in the journal Nature Neuroscience. (IANS)
