Wife turns cold-blooded killer for 'Apadbandhava Ashok'; missing mystery solved

Washington, Jun 30: Researchers in China have discovered a new type of swine flu that is capable of triggering a pandemic, according to a study published Monday in the US science journal PNAS.

Named G4, it is genetically descended from the H1N1 strain that caused a pandemic in 2009.

It possesses "all the essential hallmarks of being highly adapted to infect humans," say the authors, scientists at Chinese universities and China's Center for Disease Control and Prevention.

The researchers then carried out various experiments including on ferrets, which are widely used in flu studies because they experience similar symptoms to humans -- principally fever, coughing and sneezing. 

G4 was observed to be highly infectious, replicating in human cells and causing more serious symptoms in ferrets than other viruses.

Tests also showed that any immunity humans gain from exposure to seasonal flu does not provide protection from G4.

According to blood tests which showed up antibodies created by exposure to the virus, 10.4 percent of swine workers had already been infected.

The tests showed that as many as 4.4 percent of the general population also appeared to have been exposed.

The virus has therefore already passed from animals to humans but there is no evidence yet that it can be passed from human to human -- the scientists' main worry.

"It is of concern that human infection of G4 virus will further human adaptation and increase the risk of a human pandemic," the researchers wrote.

The authors called for urgent measures to monitor people working with pigs.

"The work comes as a salutary reminder that we are constantly at risk of new emergence of zoonotic pathogens and that farmed animals, with which humans have greater contact than with wildlife, may act as the source for important pandemic viruses," said James Wood, head of the department of veterinary medicine at Cambridge University.

A zoonotic infection is caused by a pathogen that has jumped from a non-human animal into a human.

Mangaluru/ Udupi, June 19: As many as 13 fresh coronavirus positive cases were reported in Dakshina Kannada on June 19, taking the total number of cases in the coastal district to 414. In Udupi, the total number of covid cases mounted to 1,050 with 11 new cases.

Four among the 13 patients in Dakshina Kannada had returned from Saudi Arabia and seven had returned from Sharjah recently. Two others were suffering from an influenza-like illness (ILI). All the 13 patients have been shifted to the designated COVID hospital in Mangaluru.

In Udupi, three among the 11 new covid patients are children. Four are Maharashtra returnees and two had come from Tamil Nadu. Five others have contracted infection from other positive patients. 

Only 98 cases are currently active in Udupi among 1,050. As many as 950 patients have been discharged from hospital. Two deaths have occurred in the district including one on Friday.

Abu Dhabi, Feb 17: NMC Health Plc, a hospital operator targeted by short-seller Muddy Waters, said founder Bavaguthu Raghuram Shetty resigned amid investor concern he faced a margin call and misrepresented his stake.

The board asked for Co-Chairman Shetty’s resignation and it takes effect immediately, according to a person with knowledge of the situation. NMC has lost four board members since Friday, including Vice Chairman Khaleefa Butti, whose holdings are also being probed. The stock, the worst performer on the FTSE-100 Index this year, fell as much as 9.2 percent Monday morning and then rebounded.

“The resignation of senior board members should be viewed positively,” said Abdulla Nahlawi, an analyst at Rasmala Investment Bank in Dubai. “The credibility of the current board has been jeopardized with the unfolding of the recent events.”

NMC shares lost almost half their value the first week of February on speculation the company’s main investors faced a margin call, in which banks seize shares pledged as collateral. NMC said Friday that First Abu Dhabi Bank and Al Salam Bank Bahrain obtained 20 million shares in the company from BRS International Holding, an investment vehicle of NMC’s top shareholders. The banks sold more than 8 million of those shares as “enforcement of security,” NMC said.

NMC operates the largest medical network in the United Arab Emirates and in 2012 became the first Abu Dhabi company to list in London. The shares started teetering in mid-December when Muddy Waters alleged that NMC manipulated its balance sheet and inflated the prices of companies it acquired.

Shetty, 77, was born in India and founded NMC in the 1970s after moving to Abu Dhabi. His spokesman said a legal review of the situation is ongoing and declined further comment.

Chief Investment Officer Hani Buttikhi and board member Abdulrahman Basaddiq also stepped down because they were appointees of Shetty and Butti, NMC said, adding that they had no knowledge of the share transfers.

Questions remain over the role of Shetty’s family at the company. His wife and son-in-law both hold roles in senior management.

Almost 10 per cent of NMC’s freely traded shares are shorted, according to Markit Securities data. In mid-December about a third of them were.

Last week GKSD Investment, an investment company backed by hospital investors, said it’s studying a possible offer for NMC. Under U.K. takeover rules, it has until March 9 to make a bid.

NMC has said Muddy Waters’s claims are false and the company hired former FBI Director Louis Freeh to conduct an independent review. The review is due to be completed before the company issues its financial results in March, the person said.

NMC said Mark Tompkins will continue as the company’s sole chairman.
