In a conference organized by the DOST, experts from the University of California and the Oxitec Technologies of the United Kingdom (UK) presented the aspects of genetically-engineered male mosquitoes to the scientists and biotechnology experts of DOST and other concerned agencies at the Hyatt Hotel last 12 September 2011. “Male mosquitoes were basically used because they don’t bite humans and they have significant role in the reproduction of mosquitoes,” said Dr. Anthony James, Professor at the Department of Microbiology and Molecular Genetics, University of California. Through the “Release of Insects carrying a Dominant Lethal” (RIDL) technology, male mosquitoes are engineered to contain a gene that can be passed on to female mosquito by mating. The mating results to unviable female mosquito offspring. “The gene targets a certain muscle on a female mosquito that affects the development of wings – thus flightless female mosquitoes are produced.” The flightless female mosquito can’t seek host to take blood meal. Thus, it can’t spread the dengue virus,” said Dr. James. “This is also lethal for female mosquitoes because they are more likely to be eaten by predators. Continuous release of male mosquitoes in the wild will eventually cut-off the population of deadly mosquitoes,” added Dr. James. “From a decade of research in the laboratory, GM mosquitoes have been tested in an open field in Grand Cayman Island and Malaysia. We are extremely successful,” said Dr. Luke Alphy, Chief Scientist Department of Zoology, University of Oxford, United Kingdom and Co-Founder of the Oxitec Technologies – a biotech company based in UK. “The project was also approved by regulating bodies for import and contained testing in Brazil, France, India and Singapore.” Oxitec has released 3 million GM mosquitoes, an estimated 10 males for every native female, in the wild within a 40-acre area of the Grand Cayman Island. According to studies, the population of mosquitoes dropped by 80% compared to the regions of the island where there were no released GM male mosquitoes. “The technology is ready to use. In fact, our team is going out to different countries to promote it and be of help to control the diseases brought by mosquitoes,” said Dr. Alphy. “Once mosquitoes are released in the wild, we expect to see suppression of mosquito’s population within two to three months over a large area.” However, the DOST clarifies and assures the public that they will study the technology first, prior to its approval and implementation in the Philippines. “Our main goal here is to eliminate dengue, not to bring harm in our country,” said Dr. Jaime Montoya of the Philippine Council for Health Research and Development (PCHRD) of DOST. “We know that Filipinos are highly aware of issues like genetically-modified organisms (GMOs) and we expect more comments from the public. In fact, the Philippines is first in Asia to commercialize GMO. Now, we have awareness, we know the pros and the cons. We are now in a better position to decide whether this technology will be useful or not. After all, we have the National Committee on Biosafety who will be the ultimate policy approving body for GMOs in the country, “added Dr. Montoya. Because it is a new technology, Dr. Montoya said that it is important to consider different measures needed to be in place to maintain the technology. “We need manpower to do the confined trials or field trials, refine the biosafety framework particular for GMM, infrastructures, and get the engagement of the community,” concluded Dr. Montoya. | ||

In the Philippines, 70, 000 dengue cases were reported from January to September this year. Though it is 25 percent lower compared to the cases of the same period last year, the government vows to intensify its campaign against dengue. Aside from the nationwide distribution of the Ovicidal Larvicidal (OL) trap technology, the government is exploring other possible interventions such as the use of the geographic information system (GIS). A recent study by Prof. Fernando Garcia from the College of Public Health, University of the Philippines Manila (UPM), An Examination of the Spatial Factors of Dengue Cases in Quezon City, A Geographic Information-Based Approach, showed that GIS can help the government in the quick identification of dengue high risk areas. “In order to effectively control the dengue disease, it is important to understand the vector – the Aedes mosquitoes and the contributing factors that influence its occurrence and reoccurrence,” said Prof. Garcia. In the study, environmental factors such as build-up structures, existing land use or cover types, and presence of water networks were assessed in relation to the occurrence of dengue incidence in Quezon City. 2005-2008 data on dengue incidence from the Quezon City Health Office were used as reference. Together with identified environmental factors, the dengue frequencies were mapped, overlaid, and analyzed. Results of the study showed that the highest frequency of dengue is evident in the eastern portion of Quezon City, covering the Barangays of Matandang Balara, Batasan Hills, Commonwealth and Payatas. Dengue frequencies in these areas were consistently high throughout the four -year period of data. “These are the adjacent areas within the La Mesa Dam Reservoir – part of the river basins of the neighbouring cities and localities such as San Juan Pasig, Marikina, Tullahan, Tenejeros, and Meycauayan, Bulacan.” On the other hand, population density is not significant to dengue occurrence. Based on the data gathered, both high densely populated (Barangay Bagong Pag-asa and Tatalon) and low densely populated areas (Barangay Batasan Hills, Holy Spirit, Payatas, Commonwealth, Matandang Balara and Bahay Toro) in Quezon City recorded high dengue incidence.“In fact, many areas with high dengue incidence were low densely populated barangays,” added Prof. Garcia. The study also examined why dengue incidences are higher in some areas, taking into consideration other factors such as geographical attributes, livelihood activities, and hygiene practices in the community. “For example, poor sanitary practices of people, especially those living near dumpsites, may contribute to high occurrence of dengue and other occupational diseases such as parasitic, enteric and viral infections,” said Prof. Garcia. Incidence of dengue is also higher in areas where there are Soil Organic Carbon (SOC). These are areas where diverse combination of materials such as plants, animals, and other decaying materials are stored. “It maybe in these locations where segregation of waste materials is not properly done, leaving behind solid waste materials such as containers with decaying materials. This makes it more conducive for dengue mosquitoes to lay their eggs,” said Prof. Garcia. “With GIS, we can create dengue risk maps essential in the formulation of evidence -based decisions. Local authorities will be in a better position to target priority areas and decide where to put scarce resources for programs and projects that will address further disease outbreaks,” Prof. Garcia concluded. | ||

Jack Canfield's 90-day goal challenge, one of my financial mentor
Updates on Bo Sanchez Soulfood my financial mentor
Do You Have Patterns Of Success?
It’s easy to be a good boy or good girl once in awhile.
It’s easy to love your spouse once in awhile. (Even a drunk wife-beating husband who maintains 3 girlfriends can love his wife once in a while.)
It’s easy to eat your veggies once in awhile.
It’s easy to stop smoking once in awhile.
It’s easy to come to a prayer meeting like the Feast once in awhile.
But if you want massive changes in your life, you’ve got to do it all the time. The Bible says, And let us not grow weary of doing good, for in due season we will reap, if we do not give up. (Galatians 6:9)
Success, after all, is all about patterns.
Create Patterns Of Success
Do you have to succeed in your life?
If you want success, you need to create Patterns of Success. Habits. Rituals. Almost non-thinking, second nature, repeated behavior.
If you want to be happier in your life, you’ve got to create Patterns of Happiness.
If you want to be healthy in your body, you’ve got to create Patterns of Health.
If you want more love in your relationships, you’ve got to create Patterns of Love.
Here’s a fact: According to research, 90% of our behaviors are patterns. Habits. Rituals. Ninety percent!
You Can’t Help But Win
Here’s the good news. If you create Patterns of Success, it’ll be very difficult not to succeed. You can’t help but win. Even if you tried losing, it won’t be easy.
Example? I was reading about Larry Bird.
Larry Bird is in the Guinness Book of World Records as one of the best shooters in basketball history.
One day, Larry was doing a television commercial.
The director told him, “Larry, here’s what I want you to do. I want you to take a shot and miss.”
Larry said, “Sure!”
“Lights, Camera, Action!” the production assistant shouts.
Larry takes the ball, throws it into the air, and it goes straight into the ring. “Oops,” Larry says, “Sorry!”
“It’s okay,” the Director says, “Miss the shot this time, Larry. Take 2!”
“Lights, Camera, Action!” the man with the clapper hollers again.
Larry grabs the ball, looks up, and shoots… and the ball goes in again. “Oh no,” he says, “I really am very sorry.
“Take three!” the Director shouts again.
Guess what. On the third try, Larry drills it in again.
This is astounding: It took Larry 15 takes before he finally missed a shot.
Why? Because for the past 30 years, Larry had a Pattern of shooting that ball in. His conscious mind was telling him, “Miss the shot!” But his subconscious mind was telling his entire body, “Shoot it in!” And most of the time, the subconscious mind wins.
I read something amazing. For years, after each team practice, Larry Bird would stay behind. When all the players were gone, he’d shut off the lights in the court. And in semi-darkness, he’d shoot for thirty more minutes.
Let me repeat: When you have a Pattern of Success, it’ll be very difficult not to succeed in life.
Focus On Your Magic 20%
And the great thing about success is that it doesn’t involve a humongous list of habits.
Remember the Pareto Principle? 20% of causes produce 80% of the results.
So here’s how to change your life: Focus on the Magic 20% of habits that produce 80% of the results you desire.
I’ve found this true in my life. If you want to be successful in any area of your life, it really boils down to three or four habits only in each of area.
Let me give you three examples from my life…
