Dumped in Ch'garh BJP govt-run shelter, hundreds of cows starved to death

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

New Delhi, Feb 1: An extremist today fired shots at anti-CAA protesters at Shaheen Bagh in Delhi, just three days after another extremist fired at protesters at nearby Jamia Millia University. This is the second daylight shooting in which the police caught the man only after the shots were fired.

The man, apparently a fan of BJP leaders including Narendra Modi and Amit Shah, shouted "Jai Sri Ram" as he fired shots standing near police barricades put up at the south Delhi locality where hundreds of women and children have sat on the road in protest for more than a month. He was caught by the police. No one was injured. 

The shooter was also heard saying: "Humare desh mein sirf Hinduon ki chalegi aur kisi ki nahi (in our country only Hindus will prevail)." He had allegedly come to the area in an auto.

A witness said the man fired two-three times, standing right next to the police, not at the spot of the protest but close enough to a large crowd of unarmed men, women and children. 

"We suddenly heard gunshots. This person was shouting Jai Shri Ram. He had a semi-automatic pistol and he fired two rounds. The police were standing just behind him," said the witness, a volunteer at the protest.

"When his gun jammed, he ran. He tried to fire again, then tossed the gun into the bushes and tried to escape. Some of us and the police caught him, the police dragged him away," he added. Protesters questioned whether the police were more focused on keeping an eye on them rather than tackling crimes like this.

Police officer Chinmay Biswal said the man had fired shots in the air. "The man had resorted to aerial firing. Police immediately overpowered and caught him," he said.

This incident - the second shooting in Delhi at an anti-CAA protest -- has chilling similarities to the one that took place just two km away at Jamia university on Thursday, when a 17-year-old Class 12 boy from Uttar Pradesh fired a crude pistol at unarmed protesters with dozens of policemen behind him, watching. The teen, who left home claiming he was going to school, took a bus to Delhi intending to target Shaheen Bagh but landed at Jamia next-door after an auto-driver dropped him off there to avoid the traffic chaos.

The shootings have taken place in quick succession after controversial slogans of "Goli Maaro Sa***n Ko (shoot the traitors)" were chanted on Monday at a Delhi campaign rally of Anurag Thakur, the Union Minister of State for Finance, who was part of the team involved in Budget 2020 announced today.

Mr Thakur was banned from campaigning in Delhi for three days for egging on BJP workers to shout the "Goli Maaro" slogan.

Delhi Chief Minister Arvind Kejriwal slammed Home Minister Amit Shah, to whose ministry the Delhi Police reports to, over the two shooting incidents. "What have you done to our Delhi, Amit Shah ji? Bullets are being fired in broad daylight... Law and order is being criticised constantly. Elections will come and go, politics will keep happening, but for the sake of the people of Delhi, please focus on fixing law and order," he tweeted.

The Shaheen Bagh protest has attracted attention from across the country in the protests against the CAA or the Citizenship (Amendment) Act, which makes religion a criterion for citizenship. Critics say the law discriminates against Muslims as only non-Muslims from neighbouring Pakistan, Afghanistan and Bangladesh can become Indian citizens if they fled religious persecution and entered India before 2015.

Of late, critics of the Shaheen Bagh protests, mainly pro-CAA activists, have attacked the month-long sit-in on a key road in Delhi connecting to Noida. They say the protest has become a traffic nightmare for commuters.

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.
