Novel vaccine proven effective against Zika virus

Washington, Aug 8: A uniquely designed experimental vaccine against Zika virus has proven powerful in mice, scientists have found, paving the way for preventing the infection that causes babies to develop serious birth defects.

The vaccine, developed by researchers at Ohio State University in the US employs an uncommon two-pronged approach to fighting the virus, which is spread by mosquitoes and is most serious for pregnant women and their foetuses.

The single-dose vaccine, carrying the genes for two or three Zika proteins, proved effective in triggering an immune response that prevented later infection by Zika virus, researchers said.

"In this study, the vaccine was potent, safe and highly effective, at least in the short term. There's a long way to go, but we think this is a promising candidate for a human vaccine," said Jianrong Li, a professor at Ohio State, who led the study published in the journal Nature Communications.

Babies born to Zika-infected mothers are sometimes born with a birth defect called microcephaly.

Other complications include miscarriage, stillbirth and other birth defects. Research also suggests that a small percentage of people infected with the virus can contract Guillain-Barre syndrome, which affects the nervous system.

There's no vaccine available currently and the only protection against Zika are preventative measures such as insect repellant, staying indoors and wearing long sleeves and pants.

Shan-Lu Liu, a study co-author from Ohio State, said the experimental vaccine holds particular promise because it appears to afford an adequate immune response with one dose.

In hard-to-reach and resource-poor areas, that becomes especially valuable, he said.

The study included experiments in mice with severely compromised immune systems - a necessary step to make sure that mice could get sick after infection with Zika virus.

When the vaccinated mice were exposed to Zika virus, their weak immune systems fought it off swiftly and efficiently, convincing the research team that their design had worked.

The early success with this vaccine has encouraged this team to use the same approach to fight other related viruses, including dengue fever, the researchers said.

Washington, Jul 7: The US military "will continue to stand strong” in relationship to a conflict between India and China or anywhere else, a top White House official said on Monday, after the navy deployed two aircraft carriers to the South China Sea to boost its presence in the region.

"The message is clear. We're not going to stand by and let China or anyone else take the reins in terms of being the most powerful, dominant force, whether it's in that region or over here,” White House Chief of Staff Mark Meadows told Fox News.

“And the message is clear. Our military might stands strong and will continue to stand strong, whether it's in relationship to a conflict between India and China or anywhere else,” Meadows said in response to a question.

He was told that India banned Chinese apps because Indian soldiers were killed by Chinese troops last month and asked what's mission of the two aircraft carriers - the Ronald Reagan and the Nimitz - and what's America's mission.

The troops of India and China are locked in an eight-week standoff in several areas in eastern Ladakh including Pangong Tso, Galwan Valley and Gogra Hot Spring. The situation deteriorated last month following the Galwan Valley clashes that left 20 Indian Army personnel dead as the two sides significantly bolstered their deployments in most areas along the LAC.

The Chinese military on Monday began withdrawing troops from the Galwan Valley and Gogra Hot Spring after National Security Advisor Ajit Doval and Chinese Foreign Minister Wang Yi held lengthy talks on Sunday. Doval and Wang are also the special representatives on the India-China boundary talks.

The United States has sent two of its aircraft carriers to the South China Sea. “Our mission is to make sure that the world knows that we still have the preeminent fighting force on the face of the globe,” Meadows said.

President Donald Trump has invested more in the US military, more in not only the hardware, but the men and women who serve so sacrificially each and every day, he said. “He (Trump) continues to do so,” he added.

China is engaged in hotly contested territorial disputes in both the South China Sea and the East China Sea. Beijing has built up and militarised many of the islands and reefs it controls in the region. Both areas are stated to be rich in minerals, oil and other natural resources and are vital to global trade.

China claims almost all of the South China Sea. Vietnam, the Philippines, Malaysia, Brunei and Taiwan have counter claims over the area.

Appearing on the same Fox News on Monday talk show with host Brian Kilmeade, influential Republican Senator Tom Cotton said that the US aircraft carriers are headed to the South China Sea to thwart off any Chinese misadventure against Taiwan or other countries in the region.

"That's one of the reasons why we have those aircraft carrier groups in the South China Sea. I mean, look what China did in the southwest. It's essentially invaded India over the last few weeks and killed Indian soldiers,” Cotton said.

"No country on China's periphery, right now, is safe from Chinese aggression. All those countries want a close relationship with the United States. We ought to have one,” Cotton said.

New York, Feb 26:  A new wearable sensor that works in conjunction with artificial intelligence (AI) technology could help doctors remotely detect critical changes in heart failure patients days before a health crisis occurs, says a study.

The researchers said the system could eventually help avert up to one in three heart failure readmissions in the weeks following initial discharge from the hospital and help patients sustain a better quality of life.

"This study shows that we can accurately predict the likelihood of hospitalisation for heart failure deterioration well before doctors and patients know that something is wrong," says the study's lead author Josef Stehlik from University of Utah in the US.

"Being able to readily detect changes in the heart sufficiently early will allow physicians to initiate prompt interventions that could prevent rehospitalisation and stave off worsening heart failure," Stehlik added.

According to the researchers, even if patients survive, they have poor functional capacity, poor exercise tolerance and low quality of life after hospitalisations.

"This patch, this new diagnostic tool, could potentially help us prevent hospitalizations and decline in patient status," Stehlik said.

For the findings, published in the journal Circulation: Heart Failure, the researchers followed 100 heart failure patients, average age 68, who were diagnosed and treated at four veterans administration (VA) hospitals in Utah, Texas, California, and Florida.

After discharge, participants wore an adhesive sensor patch on their chests 24 hours a day for up to three months.

The sensor monitored continuous electrocardiogram (ECG) and motion of each subject.

This information was transmitted from the sensor via Bluetooth to a smartphone and then passed on to an analytics platform, developed by PhysIQ, on a secure server, which derived heart rate, heart rhythm, respiratory rate, walking, sleep, body posture and other normal activities.

Using artificial intelligence, the analytics established a normal baseline for each patient. When the data deviated from normal, the platform generated an indication that the patient's heart failure was getting worse.

Overall, the system accurately predicted the impending need for hospitalization more than 80 per cent of the time.

On average, this prediction occurred 10.4 days before a readmission took place (median 6.5 days), the study said.

"Aligning the vision and aspiration of the Institute for the future with the vision and contribution of late Arun Jaitley, the Government has decided to rename National Institute of Financial Management (NIFM) as the Arun Jaitley National Institute of Financial Management(AJNIFM)," the statement said.

NIFM has become a premier resource centre to meet the training needs of the central government for senior and middle level of management in the fields of public policy, financial management, public procurement and other governance issues for promoting highest standards of professional competence and practice.
