A notorious ornamental plant, commonly known as dumb cane, has been found to be useful in controlling the spread of cancer cells in the body.

A study conducted by students from Notre Dame of Dadiangas University in General Santos City discovered that dumb cane plant, scientifically known as Dieffencachia maculata, contains active ingredients that cause antiangiogenesis, a process that inhibits the growth and development of new blood vessels in the body.

Antiangiogenesis controls the spread of tumour cells in the body by disabling the transport of nutrients toward the cancerous cells. Normally, tumour starts from a single cell and divides to make more cancer cells. The growth of malignant cells will depend on the availability of specific nutrients being transported by blood vessels.

In laboratory experiments, researchers separately analyzed the effects of dumb cane’s essential oil, leaf extracts, mineral water and Simvastatin (an anti-cholesterol drug with anti-angiogenic effects) to wild duck embryos. Results showed that embryos exposed to dumb cane’s essential oil and leaf extracts had lower blood vessel branching points than the embryos in the mineral water solution. The antiangiogenic properties of both dumb cane’s essential oil and leaf extracts were also comparable to Simvastatin.

Toxicity tests, meanwhile, revealed that dumb cane’s essential oil and leaf extracts are tolerable to humans. Using human lymphocytes, researchers determined the actual toxicity of dumb cane’s essential oil and leaf extracts on human cell. Though dumb cane contains glycoside, an organic poisonous compound, researchers explained that cell viability after 24 hours of incubation is still high.

With the findings, researchers claimed that dumb cane’s ability to prevent blood vessel growth and development can be possibly used in the formulation of anti-cancer drug to help prevent the spread of cancer cells in the human body. They recommended further studies to isolate the specific components of dumb cane responsible for antiangiogenic activity and determine the appropriate concentrations for pharmaceutical purposes.

Good news for those who want to study abroad! The ASEAN Foundation (AF) and Chulabhorn Graduate Institute have signed an agreement to develop highly qualified human resources in the area of science and technology within ASEAN member countries through the Chulabhorn Graduate Institute – ASEAN Foundation Post-Graduate Scholarship program in Science and Technology.

Five scholarships for ASEAN Nationals are offered for the following Master’s degree programs:

  1. Applied Biological Sciences: Environmental Health;
  2. Environmental Toxicology;
  3. Chemical Biology

The application for the CGI-AF Scholarship Program is due on 30 October 2013.

The recent deaths of three government officials due to untested stem cell treatments has bought to light the lack of government oversight on human health research. The numerous stories on potential cures and a vaccine for dengue bring a lot of hope, but also concerns over the safety of these treatments.
The establishment of guidelines and government oversight failsafes on research safety and ethical human health research has finally come to fruition with the passage of Republic Act 10532 or The Philippine National Health Research System Act of 2013 (PNHRS) last June 1.

To help address the issues and challenges facing the Philippine research industry, the first public consultation for the implementing rules and regulations (IRR) of PNHRS was held ON June 25  in Davao City.

Stakeholders from different sectors of the academe, the health industry, the public and private sector, different government agencies, local government units and the media were invited to help point out any flaws, inconsistencies or inadequacies in the draft IRR.
Two more public consultations will be held, tomorrow in Iloilo and next in Manila, before a final draft of the IRR would be submitted.

7th PNHRS Week

On August 7-9, 2013, the 7th Philippine National Health Research System (PNHRS) Week will be held at the Plaza del Norte Hotel and Convention Center, Laoag City, Ilocos Norte with the theme “People at the Center of Health and Health Research.

Hosted by the Region 1 Health Research and Development Consortium, the PNHRS Week celebration will provide a platform for the different stakeholders in health R&D to interact, to learn from each other, to share information and experiences, to voice their concerns, to contribute research-based solutions to health problems, among other things.

Expected to grace the three-day celebration were Provincial Governor Maria Imelda Josefa R. Marcos, Secretary Mario G. Montejo of the Department of Science and Technology (DOST) and Secretary Enrique T. Ona of the Department of Health (DOH).

Around 500 participants from all the 17 regional health research consortia are expected to participate in the event. For more information, please contact PNHRS secretariat at telephone numbers: (02) 8377534 or (02) 8377537 or visit PNHRS website at http://www.healthresearch.ph/.

PNHRS Week is held annually on the second week of August by virtue of Presidential Proclamation No. 1309 signed in 2007.

PH seizes global recognition in health research

We have successfully won the bid to host Global Forum for Health Research in 2014, it’s a great opportunity for the voices of our people to be heard in the global health research arena,” said Dr. Jaime C. Montoya, Executive Director, Philippine Center for Health Research and Development (PCHRD-DOST) during PCHRD’s 31st anniversary last March 18, 2013 at Sofitel Philippine Plaza.

The Global Forum for Health Research in 2014 will be the very first biennial meeting jointly organized by the Council on Health Research for Development (COHRED) Group and the Philippine government, through the Department of Science and Technology (DOST) and Department of Health (DOH).
