Gov’t info officers urged to use social networking

Govt info officers urged to use social networking

ILOILO City Philippine Information Agency (PIA) Region 6 Director Janet Mesa urged government information officers to use online social networking in information dissemination.

Move on to social networking through the use of the internet and be on social networking sites such as Facebook, Twitter and MySpace. Open your municipalities to these new exciting outlets of information and use them effectively to disseminate government information, said Mesa during the induction of the new set of officers of the Association of Government Information Officers in Iloilo held at Damires Hills in Janiuay, Iloilo.

Mesa also urged them to be consistent in their attendance in meetings and submission of accomplishments of their agencies and local government units for dissemination.

Mesa said a municipality is active and efficient not only because of the leadership of the local chief executive but also because of the information support given by the information officers.

The more you talk, the more people will know and support development, said Mesa as she congratulated the new set of officers headed by Juvy Gaton, head of the Information Division of the Department of Agriculture Regional Field Unit 6.

Janiuay Mayor Frankie Locsin inducted Gaton and the other officers that included:

* David Israel Sinay of the Department of Environment and Natural Resources 6 vice president for National Government Agencies

* Susan Jovero of the municipality of Pavia vice president for local government units

* May Castillo of the Department of Social Welfare and Development 6 secretary

Secret of HIV's natural born killers out

Scientists say they have found a key piece in the puzzle as to why a tiny minority of individuals infected with HIV have a natural ability to fight off the deadly AIDS virus.

In a study they say holds promise for an HIV vaccine, researchers from four countries have reported the secret lies not in the number of infection-killing cells a person has, but in how well they work.

Only about one person in 300 has the ability to control the human immunodeficiency virus (HIV) without drugs, using a strain of 'killer' cells called cytotoxic T lymphocyte (CTL) cells, previous research has found.

Taking that discovery further, scientists from the United States, Canada, Japan and Germany reported that the strain has molecules called receptors that are better able to identify HIV-infected white blood cells for attack.

Until now, it was well known that people with HIV 'have tonnes of these killer cells', Bruce Walker, an infectious diseases expert at the Ragon Institute in Massachusetts, told AFP.

'We have been scratching our heads since then, asking how, with so many killer cells around, people are getting AIDS. It turns out there is a special quality that makes them (some cells) better at killing.'

The study looked at 10 infected people, of whom five took antiretroviral drugs to keep HIV under control while five were so-called elite controllers who remained naturally healthy.

HIV kills a type of white blood cell called CD4, leaving people with AIDS wide open to other, opportunistic and potentially deadly infections.

'What we found was that the way the killer cells are able to see infected cells and engage them was different,' said Walker.

'It is not just that you need a killer cell, what you need is a killer cell with a (T cell) receptor that is particularly good at recognising the infected cell. This gives us a way to understand what it is that makes a really good killer cell.'

Secret of HIV killer cells revealed

PARIS: Scientists said that they had found a key clue on why a tiny minority of individuals infected with HIV (human immunodeficiency virus) has a natural ability to fight off AIDS (Acquired Immune Deficiency Syndrome).

In a study they said holds promise for an HIV vaccine, researchers from four countries reported that the secret lies not in the number of infection-killing cells a person has, but in how well they work.

According to previous research, only about one person in 300 has the ability to control the human immunodeficiency virus (HIV) without drugs, using a strain of killer cells called cytotoxic T lymphocyte (CTL) cells.

Taking that discovery further, scientists from the United States, Canada, Japan and Germany reported that the strain has molecules called receptors that are better able to identify HIV-infected white blood cells for attack.

Until now, it was well-known that people with HIV have tons of these killer cells, Bruce Walker, an infectious diseases expert at the Ragon Institute in Massachusetts, told Agence France-Presse.

We have been scratching our heads since then, asking how, with so many killer cells around, people are getting AIDS. It turns out there is a special quality that makes them [some cells] better at killing, he said.

Honey Bee Killer

A parasitic mite helps spread a deadly virus among honey bee colonies.

By Cristina Luiggi | June 11, 2012

A parasitic mite (Varroa destructor) that feeds on the blood of honeybees has helped spread a deadly strain of the virus implicated in the deaths of millions of honeybees worldwide. Known as deformed wing virus (DWV), the RNA virus causes wing and abdominal deformities, suppresses the immune system, and affects the behavior of infected bees.

The mite was accidentally brought over to Hawaii 5 years ago and quickly began affecting honeybee populations, though it has yet to reach all bees on the islandsaffording researchers, led by Stephen Martin from the University of Sheffield, the unique opportunity to study infected and uninfected bee colonies. They found that the mite drastically altered the normal viral landscape of bees, which typically carry billions of different viral strains, and specifically selected for deformed wing virusincreasing its frequency in infected colonies from 10 percent to 100 percent.

Although it remains unclear how the Varroa mite helps the deformed wing virus thrive, the new study, published last week (June 8) in Science, points to effective ways to stop the spread of the virus. So the only way to control the virus is to control the levels of the mite, Martin told BBC News.

Bees exposed to neonicotinoids, a widely-used class of pesticide, navigate poorly and produce fewer queens, suggesting a role for neonicotinoids in colony collapse.

A new subtype of the flu virus is identified in Guatemalan yellow-shouldered bats, and it may share its genes with the human version.
