Bengaluru, Mar 27: Oncologist Dr. Vishal Rao, HCG Hospital Bengaluru on Friday said that human body cells release interferon chemical to kill viruses but it cannot be released by cells in the case of COVID-19 cases, leading to weak immune system. However, a therapy of specific concoction could be useful in treating COVID-19 patients.

"We got hold of some preprint suggesting that interferon is effective in COVID19," said Rao.

Speaking to news agency, he continued saying "When we withdraw blood for regular check-ups, we get buffy coat which can be used to take out cells and form interferon. These two chemicals and some other cytokines, in a specific concoction, could be potentially very useful in treating COVID-19 patients."

Rao said that they have built a concoction of cytokines which can be injected to reactivate immune system in COVID-19 patients.

"We are in a very initial stage and hope to be ready with its first set by this weekend. We have applied to the governement for an expedited review. We have also presented this before the state government" said Rao.

"We have a team of infection specialist, ICU team and other...all of us have worked together to build something that we believe. We want to serve the society at this hour of need," he added.

Dr Rao clarified that this is not a vaccine and this particular interferon therapy does not help to prevent the infection of COVID-19. However, this is focused and targeted towards COVID-19 positive patients or those who have just incubated the virus.

"We believe that in early stages as well as the patients who have just incubated, this particular therapy of interferon gama and other concoction of cytokines could be an effective method. In the late stages we are looking at specific dosage of the cells which are our own body cells which can actually be affective and could also be of use for the ventilator patients," he added.

Meanwhile, Dr Gururaj, Immunologist and Scientist told ANI that they are trying to cover two aspects, one is the early stage patients where they are trying to improve their immune systems.

"As Dr Vishal said, we are trying to see whether we can use the cytokines from our own immune cells which is a natural process but it is hampered in infected patients," said Dr Gururaj.

"In the last phase we are using cells which are used from the bone marrow of the patient or donors. We can use those cells to reduce the inflation and so called cytokines release syndrome which is basically the inflammatory response of the body," he added.

New Delhi, May 9: The Finance Ministry on Friday announced relief to those who have been facing difficulty with their residency status in India under section 6 of the Income-tax Act due to lockdown and suspension of international flights owing to COIVD-19 outbreak, as they have had to prolong their stay in India.

According to a Central Board of Direct Taxes (CBDT) release, Finance Minister Nirmala Sitharaman today allowed discounting of prolonged stay period in India for the purpose of determining residency status after considering various representations received from people who had to prolong their stay in India due to lockdown and suspension of international flights.

They expressed concern that they will be required to file tax returns as Indian residents and not as NRIs after 120 days of stay.

The Finance Ministry stated that the lockdown continues during the financial year 2020-21 and it is not yet clear when international flight operations would resume, a circular excluding the period of stay of these individuals up to the date of resumption of international flight operations shall be issued for determination of the residential status for the financial year 2020-21.

A circular also said that in order to avoid genuine hardship in such cases, the CBDT has decided that for the purposes of determining the residential status under section 6 of the Act during the previous year 2019-20 in respect of an individual who has come to India on a visit before March 22, 2020 and:

(a) has been unable to leave India on or before March 31, 2020, his period of stay in India from March 22, 2020 to March 31, 2020 shall not be taken into account; or

(b) has been quarantined in India on account of novel coronavirus (Covid-19) on or after March 1, 2020 and has departed on an evacuation flight on or before March 31, 2020 or has been unable to leave India on or before March 31, 2020, his period of stay from the beginning of his quarantine to his date of departure or March 31, 2020, as the case may be, shall not be taken into account; or

(c) has departed on an evacuation flight on or before March 31, 2020, his period of stay in India from March 22, 2020 to his date of departure shall not be taken into account."

The release said there are number of individuals who had come on a visit to India during the previous year 2019-20 for a particular duration and intended to leave India before the end of the previous year for maintaining their status as non-resident or not ordinary resident in India.

"However, due to declaration of the lockdown and suspension of international flights owing to outbreak of COVID-19, they are required to prolong their stay in India. The status of an individual whether he is resident in India or a non-resident or not ordinarily resident, is dependent, inter-alia, on the period for which the person is in India during a year," it said.
