Binabago ng Massively Parallel Sequencing (MPS) ang paraan ng pagkilala sa mga tao. (Photo credit: Christian Estrella)

Ang Massively Parallel Sequencing (MPS) ay binago ang forensic DNA analysis sa pamamagitan ng kakayahang suriin ng mga siyentipiko ang maraming DNA markers nang sabay-sabay at sa mas detalyadong paraan kumpara sa tradisyunal na pamamaraan. Gayunpaman, hindi pa rin malawak ang paggamit ng MPS sa mga bansa sa Timog-Silangang Asya.

 

Kamakailan, sinuri ng mga mananaliksik mula sa University of the Philippines Diliman – College of Science Natural Sciences Research Institute (UPD-CS NSRI) ang paggamit ng MPS sa mga forensic DNA laboratory sa rehiyon upang matukoy ang mga pangunahing hamon sa pagpapatupad nito.

 

Sa forensic DNA analysis, ang matagal nang ginagamit na standard ay ang Short Tandem Repeat (STR) profiling gamit ang capillary electrophoresis, na nakikilala ang bawat indibidwal sa pamamagitan ng pagsukat ng haba ng partikular na DNA markers. Kaya nga, puwedeng suriin ng MPS ang parehong markers, ngunit binabasa rin nito ang aktwal na DNA sequence sa loob ng mga ito, na nagbibigay ng mas detalyadong impormasyong genetiko.

 

Mga Hamon sa Paggamit ng MPS

 

Sinuri nina Christian Estrella, Maylowen Lumayna, Minerva Sagum, Maeviviene Sosing, Gayvelline Calacal, Dr. Maria Corazon De Ungria, at Jazelyn Salvador mula sa University of the Philippines Diliman – College of Science Natural Sciences Research Institute (UPD-CS NSRI) DNA Analysis Laboratory ang mga forensic DNA laboratory sa Brunei Darussalam, Indonesia, Malaysia, Philippines, Singapore, Thailand, at Vietnam sa pamamagitan ng isang online survey.


Ayon kay Estrella, ang pinakamalaking hadlang para sa mga laboratoryong wala pang MPS ay kakulangan sa pondo at pasilidad. “Mahirap magsimula ng ganitong teknolohiya kung walang sapat na suportang pinansyal. Hindi ito nakakagulat para sa mga bansang may mababa o katamtamang kita sa Timog-Silangang Asya,” paliwanag niya.

 

Para naman sa mga laboratoryong mayroon nang MPS equipment, mas marami ang kanilang kinahaharap na operational challenges, tulad ng kakulangan ng datos tungkol sa populasyon, hindi pare-parehong paraan ng pag-uulat ng resulta, at hirap sa pagsasama ng bagong teknolohiya sa umiiral na DNA databases.


Dagdag pa niya, isa pang mahalagang hamon ay kakulangan ng batas at pagtanggap sa korte. Bagama’t kinikilala na ang tradisyunal na DNA methods sa korte, may pag-aalinlangan pa rin sa MPS, lalo na dahil mahirap ipaliwanag ang ilang laboratory processes sa mga taong walang sapat na kaalaman sa agham.


Hinaharap ng MPS sa Timog-Silangang Asya


Ayon sa mga mananaliksik, may malaking potensyal ang MPS sa Timog-Silangang Asya sa kabila ng mga kasalukuyang hamon sa pagpapatupad nito. Mataas ang interes ng rehiyon sa paggamit ng teknolohiyang ito, at kung gagamitin nang stratehiko, maaari nitong pabilisin ang pagpapalawak ng DNA databases gamit ang mga markers na mas angkop sa rehiyon.


Maaaring simulan ang paggamit ng MPS sa piling forensic casework. Bagama’t epektibo ang tradisyunal na pamamaraan para sa pangkaraniwang kaso, mahalaga ang MPS sa mas komplikadong sitwasyon, tulad ng mga sample ng DNA na nasira dahil sa sunog o sakuna, o sa mga kasong may kinalaman sa malalayong ugnayang pampamilya. Kayang suriin ng MPS ang mas maliliit na DNA markers, kaya maaari pa rin itong magbigay ng kapaki-pakinabang na resulta kahit hindi na sapat ang tradisyunal na pamamaraan.

 

“Inirerekomenda naming magkaroon ang bawat bansa ng hindi bababa sa isang ganap na MPS laboratory bilang pambansang hub, kung saan maaaring sentralisahin ang forensic services upang mabawasan ang gastos at demand sa resources,” pagtatapos ni Estrella. “Ngunit magtatagumpay lamang ito kung may tuloy-tuloy na suporta sa pondo mula sa gobyerno at matibay na political commitment. Mahalaga ring mahikayat ang pamahalaan na ituring ang MPS bilang pangmatagalang pamumuhunan na nagpapalakas sa pambansang kapasidad sa forensics—hindi lamang para sa mga kriminal na kaso, kundi pati na rin sa disaster response, pagkilala sa tao, at proteksyon ng karapatang pantao.”

UP Study Identifies Opportunities and Challenges for Advanced DNA Technology in SEA Forensics

Massively parallel sequencing (MPS) is transforming the way humans are identified. (Photo credit: Christian Estrella)

Massively parallel sequencing (MPS) has transformed forensic DNA analysis by allowing scientists to examine multiple DNA markers at the same time and in much greater detail than older methods. Even so, MPS is still not widely used in Southeast Asian countries. Researchers from the University of the Philippines Diliman – College of Science’s Natural Sciences Research Institute (UPD-CS NSRI) reviewed the use of MPS in forensic DNA laboratories across the region to identify the key challenges to its adoption.

 

In forensic DNA analysis, the long-standing standard is short tandem repeat (STR) profiling using capillary electrophoresis, which identifies individuals by measuring length variations in specific DNA markers. MPS can analyze these same markers, but it also reads the actual DNA sequence within them, providing far more detailed genetic information.

 

Obstacles facing MPS adoption 

 

Christian Estrella, Maylowen Lumayna, Minerva Sagum, Maeviviene Sosing, Gayvelline Calacal, Dr. Maria Corazon De Ungria, and Jazelyn Salvador from the UPD-CS NSRI’s DNA Analysis Laboratory conducted an online survey of forensic DNA laboratories in Brunei Darussalam, Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam.

 

“For laboratories that do not yet use MPS, the biggest obstacle is funding and infrastructure—it’s difficult even to get started without financial support. This is not surprising for low- and middle-income countries in Southeast Asia,” Estrella explained. “Meanwhile, laboratories that already have MPS equipment face more operational challenges, such as limited population data, inconsistent reporting standards, and incompatibility with existing DNA databases.”

 

He added that another major challenge is the lack of legislation and court acceptance. Traditional DNA methods are already recognized in court, but for MPS, there is still uncertainty about whether courts will accept the results, especially given laboratory processes that can be difficult to explain to non-technical audiences.

 

Future directions for MPS in Southeast Asia

 

According to the researchers, the future of MPS in Southeast Asia holds significant promise despite challenges currently facing its implementation. There is strong regional interest in adopting the technology, which—if used strategically—can significantly accelerate the expansion of DNA databases using markers that are more relevant to the region.

 

Southeast Asia can start by selectively introducing MPS into forensic casework. While conventional methods work well for routine cases, MPS is valuable for challenging samples, such as degraded DNA from fires or disasters, or cases involving distant family relationships. MPS can analyze smaller DNA markers, so it can still produce usable results when traditional methods fall short.

 

“We recommend that each country establish at least one fully capable MPS laboratory as a national hub, where forensic services can be centralized to reduce costs and resource demands,” Estrella concluded. “However, this will only succeed with sustained government funding and strong political commitment. Convincing the government that MPS is a long-term investment that strengthens national forensic capacity—not only for criminal cases, but also for disaster response, human identification, and human rights protection—is key to securing that support.”

UP Scientists Gumamit ng Green Method Para Makagawa ng Silver Nanoparticles Para sa Antibacterial Applications

UP Scientists Gumamit ng Green Method Para Makagawa ng Silver Nanoparticles Para sa Antibacterial Applications

Nagsulong ang mga scientist mula sa University of the Philippines–Diliman College of Science (UPD-CS) ng greener approach sa silver nanoparticle (AgNP) synthesis sa pamamagitan ng paggamit ng gamma irradiation kasama ng natural na seaweed-derived biopolymer ι-carrageenan. Bagaman dati nang naiulat ang mga rutang gamma-radiolytic para sa pagbuo ng AgNP, ang mismong papel ng ι-carrageenan sa pag-stabilize at pag-impluwensya sa pagbuo ng nanoparticle sa ilalim ng proseso ng radiolysis ay nanatiling hindi pa ganap na nauunawaan.

 

Mga colloidal silver nanoparticles na ginawa gamit ang gamma irradiation sa iba’t ibang doses, na makikita sa pagbabago ng kulay mula walang kulay, nagiging dilaw, hanggang kayumanggi habang nagko-convert ang silver ions into antibacterial silver nanoparticles. Mas madilim ang kulay, mas mataas ang co

Sa halip na gumamit ng matatapang na kemikal, gumamit ang mga mananaliksik na sina Mon Bryan Gili, Wendell Manuel, at Dr. Marienette Vega ng UPD-CS Materials Science and Engineering Program (MSEP); Dr. Marlon Conato ng UPD-CS Institute of Chemistry (IC); at Rakshith Gowda Shankaregowda at Dr. Manh-Huong Phan ng University of South Florida ng gamma radiation at isang natural na seaweed-derived substance na tinatawag na carrageenan upang makalikha ng mga nanoparticle.

 

“Sa madaling salita, hinahayaan namin ang radiation na gawin ang ‘trabaho’ ng pagbuo ng mga particle, habang pinapanatili ng seaweed extract ang mga ito na matatag at ligtas. Pagkatapos ay sinubukan namin kung gaano kabisa ang mga particle na ito laban sa mga pangkaraniwang bacteria,” paliwanag ni Gili. Kung ikukumpara sa mga tradisyonal na chemical methods, ang pamamaraan ng mga mananaliksik ay maituturing na mas ‘green’.

 

Madalas na nangangailangan ang chemical synthesis ng mga malakas na reducing agent at stabilizer, na maaaring nakakalason at mahirap itapon nang hindi nakapipinsala sa kalikasan. Sa kanilang pamamaraan, ganap na pinapalitan ng gamma radiation ang mga kemikal na ito. Nagiging sterilized din ang mga nanoparticle habang sila’y nabubuo, na isang malaking pakinabang para sa mga medical application. “Sa pangkalahatan, nangangahulugan ito ng mas maikling proseso, mas kaunting chemical waste, at mas ligtas na produkto para sa tao at sa kapaligiran,” dagdag ni Gili.

 

Bilang isang researcher sa nuclear science, nasasabik si Gili na ilapat ang teknolohiya ng radiation sa paraang direktang nakikinabang sa kalusugan at sustainability. Ang pag-aalala para sa kaligtasan sa kapaligiran at ang lumalaking isyu ng antibiotic resistance ay nag-udyok sa kanya at sa kanyang pangkat na maghanap ng mga alternatibong paraan para sa paggawa ng mga silver nanoparticle. Maraming mga nakasanayang proseso ang gumagamit ng mga nakalalasong kemikal na maaaring makapinsala sa mga tao at sa kapaligiran.

 

“Kabilang sa mga susunod na hakbang ang pagpapabuti ng kanilang long-term stability, pagsubok sa mga ito sa mga real-world products, at pagsusuri kung ligtas silang gamitin ng tao,” sabi ni Gili. “Sa huli, inaasahan namin na ang teknolohiyang ito ay hahantong sa mura at lokal na gawang mga antibacterial material gamit ang likas na yaman ng Pilipinas at kadalubhasaan sa nuclear science.”

 

Ang kanilang papel, “Antibacterial evaluation of radiolytically synthesized silver nanoparticles with ι-carrageenan stabilizers,” ay nailathala sa Radiation Physics and Chemistry, isang journal na nagtatampok ng mga pag-aaral na nakatuon sa pananaliksik at mga pagpapaunlad gamit ang ionizing radiation sa radiation physics, radiation chemistry, at radiation processing.
