Deteksi Penyebaran Kanker Nasofaring.

Timbulnya ekspresi gen BRLF1 virus Epstein-Barr pada tumor nasofaring menjadi penanda terjadinya metastasis alias penyebaran kanker ke organ lain.

Demikian hasil penelitian Daniel Joko Wahyono untuk disertasinya, “Ekspresi Relatif Gen BRLF1 Epstein-Barr Virus (EBV) sebagai petanda progresivitas tumor karsinoma nasofaring (KNF). Hubungannya dengan polimorfisme gen reseptor sel Tß (TCRß) dan polimorfisme gen reseptor sel T? (TCR?) pejamu”.

Pemeriksaan biomolekuler dilakukan Daniel secara in vivo menggunakan contoh klinis pasien kanker. Sebelumnya, tahun 2008 para peneliti Universitas Toronto Kanada melakukan penelitian serupa tetpai secara in vitro menggunakan kultur.

Menurut Daniel, kasus kanker nasofaring (bagian teratas tekak dibelakang rongga hidung) tertinggi di Asia Tenggara, termasuk Indonesia dengan angka kejadian 6.2 per 100,000 pensusuk pertahun. “Pada umumnya, kasus kanker ini ditemukan pada populasi etnis China dan Melayu”, katanya.

An insect in the ear

In an insect crawl or flies into someone’s ear, its buzzing can sound frighteningly loud and its movements can be very distressing.

You may need to calm and reassure the victim. Make sure that he does not put his finger in his ear, as this may provoke the insect to sting or to bite.

Turn out all the light in the room except for one. Have the victim move the affected ear toward that source of light.

Gently pull the earlobe back and up to straighten the ear canal, and the insect may fly out toward the light. You can also try shinning a flashlight in the ear.
