Administering commonly used antidepressant fluoxetine to mice helped restore youthful flexibility to their ageing brain cells, showed a study.
The study provides fresh evidence that the decline in the capacity of brain cells to change, called “plasticity,” rather than a decline in total cell numbers may underlie some of the sensory and cognitive declines associated with normal brain ageing.
Scientists at the MIT revealed that in mice treated with fluoxetine, also known as Prozac, the inhibitory interneurons in the visual cortex remained just as abundant during ageing, but their arbors become simplified and they become much less structurally dynamic and flexible.
They could also restore a significant degree of lost plasticity to the cells.
“Here we show that fluoxetine can also ameliorate the age-related decline in structural and functional plasticity of visual cortex neurons,” said the scientists including lead author Ronen Eavri from MIT.
A previous study had shown that fluoxetine promotes interneuron branch remodelling in young mice, so the team decided to see whether it could do so for older mice and restore plasticity as well.
In the new study, appearing in the Journal of Neuroscience, they put the drug in the drinking water of mice at various ages for various amounts of time.
Three-month-old mice treated for three months showed little change in dendrite growth compared to untreated controls, but 25 per cent of the cells in six-month-old mice treated for three months showed significant new growth (at the age of 9 months).
But among 3-month-old mice treated for six months, 67 per cent of cells showed new growth by the age of 9 months, showing that treatment starting early and lasting for six months had the strongest effect. (IANS)
Since the 7th of December 1949, the Armed Forces Flag Day has been observed in India, annually. This one day is dedicated towards collection of funds from the citizens of India for the welfare of the ‘Indian Armed Forces personnel’. It has become a tradition to pay respect to the people who have served in the army, Navy and Airforce, on this day.
“The idea behind observing a Flag Day was to distribute small flags to the general population and in return collect donations.” The color-scheme of the flag is very similar to the ones used by fellow Commonwealth members like Cyprus, Kenya and Nigeria. The Flag Day signifies that it is the responsibility of the citizens of India to take care of the families and dependents of the armed forces personnel who fight for the country.

A need for such a day was realized by the Government after India gained Independence from the British rule. In order to manage the welfare of its defence personnel, the Defence Minister of India and a committee together decided to recognize 7th December as the Flag Day. This decision was taken on the 28th of August 1949.
The then Prime Minister Jawaharlal Nehru inaugurated the day saying that,
“A few weeks ago, I visited Indo-China and saw our officers and men attached to the International Commission there. It gave me a thrill to see their smart bearing and the good work they were doing in that distant land. What pleased me still more was their general popularity with the people there. By their efficiency as well as their friendliness, they enhanced the reputation of India. Among them were people from all parts of India. They observed no provincial or other differences amongst themselves. I am sure my countrymen will be pleased to learn of them and would like to indicate their appreciation of these young men who serve our country both here and elsewhere so well. A way to indicate that appreciation is to contribute to the Flag Day Fund.”
The fund is collected through official and non-official means with the help of voluntary organizations. The Kendriya Sainik Board, which is under the Ministry of Defence, arranges for the collection of the fund.
The Defence Ministry of India decided to integrate all the related welfare funds into a single unit called the Armed Forces Flag Day fund. The funds that were integrated are:
- Amalgamated Special Fund for War Bereaved, War Disabled and other ex-Servicemen/Serving Personnel
- Flag Day Fund
- St Dunstan's (India) and Kendriya Sainik Board Fund
- Indian Gorkha Ex-Servicemen's Welfare Fund

Problems have to be resolved by and welfare of the ex-servicemen and dependents are mostly settled by the States and the Union Territories, although it was to be a shared responsibility between the Union Government, the State Governments and the governments of the Union Territories. In order to help the Central Government in carrying out this process, there are 32 Rajya Sainik Boards and 392 Zila Sainik Boards. The Kendriya Sainik Board, the Rajya Sainik Board and the Zila Sainik Board are all responsible for the policy formulation and implementation of resettlement and welfare schemes for ex-servicemen, widows and their dependents residing in their respective States or Union Territories or Districts.(Keywords : armed, forces, flag, india, independance, donation, citizen, army, navy, airforce, tradition, respect, government, state, center, union territory, district, funds.)

Social media platforms have come under increased scrutiny of late for their alleged role in spreading misinformation, fake news, abusive and defamatory content and direct incitement to violence. It has become routine for state and local level administrations to temporarily ban access to social media platforms in areas that report tension and fears of violence.
A parliamentary committee has recently submitted a set of recommendations to regulate social media platforms. One major recommendation is to treat them as publishers while the other is to form a regulatory body on the lines of Press Council of India to regulate their activities. (IANS/SP)
