Krishnagiri, Feb 24: Vidya Rani, daughter of dead sandalwood smuggler Veerappan, joined the BJP on Saturday at an event organised in Tamil Nadu's Krishnagiri.

Party general secretary Muralidhar Rao and former Union Minister Pon Radhakrishnan were present at the event.

"I want to work for the poor and underprivileged irrespective of their caste and religion. Prime Minister Narendra Modi's schemes are for the people and I want to take them to the people," said Vidya Rani.

Besides Vidya Rani, the event saw as many as 1,000 members from other political parties join the BJP.

University of Oxford researchers have claimed that a cheap and widely available drug called dexamethasone can help save the lives of patients who are seriously ill with coronavirus.

Scientists working on the Recovery Trial found the drug could help patients on ventilators and oxygen, but had no effect on those who did not need help breathing.

“Based on these results, one death would be prevented by treatment of around eight ventilated patients or around 25 patients requiring oxygen alone,” researchers said in a statement.

Matt Hancock, the health secretary, tweeted: “This global first exemplifies the power of science.”

“I’m absolutely delighted that today we can announce the first successful clinical trial for a treatment for Covid-19,” Mr Hancock said.

Recovery Trial experts said a randomised group of 2,104 patients was given 6mg of dexamethasone per day for 10 days, while another group of 4,321 were given normal treatment.

Dexamethasone reduced deaths by one-fifth in patients on oxygen feeds and by one-third in those who needed a ventilator to breathe, preliminary results showed.

Mr Hancock added: “This is a huge step forward and it’s because we’ve backed the science.”

Martin Landray, professor of medicine and epidemiology at the Nuffield Department of Population Health, University of Oxford, and one of the trial’s chief investigators, said in a statement: “These preliminary results from the Recovery Trial are very clear – dexamethasone reduces the risk of death among patients with severe respiratory complications.

“Covid-19 is a global disease – it is fantastic that the first treatment demonstrated to reduce mortality is one that is instantly available and affordable worldwide.”

Bengaluru, Mar 28: Sun Tsu, in 'The Art of War' speaks of a skilful general who can subdue his enemy without any fighting. This constitutes the ultimate triumph which is referred to as stratagem. Today, we would need one such when we are faced with the '21-day corona challenge' for India.
Nearly four weeks back, Dr Jyothsna Rao, Dr Gururaj Rao and I sat across the OPD in the afternoon at HCG Bengaluru discussing our ongoing cancer immunology research. While on this topic, we drifted into the discussion on the coronavirus. During this engaging discussion, we wondered the similarity of the enigma between the virus and cancer. I paused to ask Dr Jyothsna and Dr Guru - how we wish we could do something against this virus.
Dr Jyothsna is a PhD from NCBS and had worked under Dr Ralph Steinman, physician and researcher from Rockefeller University, who won the Nobel Prize for his discovery of the dendritic cell and its role in adaptive immunity in 2011. Dr Gururaj is a molecular and cell biologist who did his PhD at the Chapel Hill, University of North Carolina and is the Director of iCrest.
Jyothsna while hearing our perplexing conversation on the covid intervened, "Yes, surely. I think we should take a break from cancer and focus on the innate and adaptive immunity role in COVID-19."
Thus began this sincere attempt to relook the human immune system from the eyes of the COVID-19.
We have 10 types of immune cells at the least which are widely dispersed in millions across the body. When our body is invaded by a foreign organism (bacteria, fungi or virus), these cells work with each other to destroy the invader.
Now, the question is - how do the immune cells talk to each other? They use small-molecule substances called cytokines (cyto means cells; kine means movement). There are many cytokines that are involved in work on the immune system. The most relevant for viruses are interferons.
Interferons (IFN) as the name reflects have an ability to interfere with the viral activity and stop their multiplication. These specialised signal proteins are released by our cells in response to a viral attack to forewarn other cells. They help build the antiviral proteins within the cells to kill the virus as it tries to invade the new cells.
Historically, interferons are a group of cytokines known to be potent antiviral agents against viruses and a hallmark cytokine induced by the host upon viral infections. Interferons possess unique immunoregulatory activities and are signature cytokines released by (TH1) T immune cells, which are crucial in viral infections.
As the outbreak of COVID-19 grapples us, an urgent need for finding strategies to combat the virus is growing. Coronaviruses (CoVs) are a group of RNA viruses. In patients infected with coronavirus, it was indicated that the activation of the IFN does not occur until 48 hours post-infection. Thus the delayed IFN-related antiviral response by the healthy cells leads to coronavirus evade the immune response.
Numerous studies have presented the success in defeating CoVs by the direct administration of IFNs. In a combination as a concoction, it was shown to synergistically inhibit the virus replication in vitro.
Moreover, it is understood that the earlier induction of IFNs in children although they have a less developed immune system could be the reason behind the children being least affected.
The key to success in reducing the disease fatality might be the stimulation of the immune responses to trigger IFN production at the very early stages of the disease, which might be done through the administration of IFN. Despite the evidence for the efficacy of IFNs in treating CoV-induced infections, the proper dosing and ideal timing for such interventions needs to be verified in clinical trials.
For the later stages of the diseases in advance stages where patients are on ventilator and have developed respiratory distress, we propose to utilise the mesenchymal cells derived from donor bone marrow that have been known to treat acute respiratory syndrome. Mesenchymal cells are known to possess anti-inflammatory activity and thus used often in autoimmune diseases.
With this scientific background, we have activated T cells from healthy donors, in a cGMP facility at iCrest - HCG hospital with an enriched cocktail of cytokines rich in Interferons. Injections of this cocktail we believe will result in a surge of cytokines in the body of the infected person and will boost his ability to fight the virus in the early phases. We are in the initial phases of this study and hope to be ready in the coming weeks with meaningful data on its potential utility.
Currently, it awaits government approvals (Union and state) and we have applied to central drugs authority for their initial evaluation and further directions.
As my Guru often expounded the philosophy of 'Seva' - the goal of education is knowledge, the end goal of knowledge is service. In this attempt to serve our fellow humans at this brink of unprecedented crisis, medical fraternity stands with you and promises to do our best for your safety.
We assure to exhaust every bit of our spirit in this fight against coronavirus. We have lost the sight of shores and travelled thus far, but that is the mandatory first step to cross the ocean. Are we going to succeed in this battle, is something only time will answer.
