Kodi mumamva ngati kuti malangizo a dokotala sakugwirizana kwenikweni ndi zomwe thupi lanu likufuna kapena zosowa? Chabwino, simuli nokha. Ndipo pali udokotala watsopano pafupi ndi ngodya, womwe umatchedwa "mankhwala opangira makonda," omwe amagwiritsa ntchito kutsatizana kwa DNA kupanga mankhwala opangidwa mozungulira majini anu apadera. (Pakadali pano, nazi Njira 8 Zopangira Bwino Kusankhidwa Kwa Dokotala Wanu.)

Zomwe zikutanthawuza: Nthawi zambiri, zomwe zimafunika ndi kuyesa magazi kapena kupukuta pakamwa pa labu kuti apange mapu a DNA yanu, akutero Erica Woodahl, Ph.D., katswiri wa biochemist ku yunivesite ya Montana. "Anthu omwe ali ndi matenda omwewo omwe amathandizidwa ndi mankhwala omwewo amakhala ndi mayankho osiyanasiyana," akufotokoza Woodahl. "Ngati titha kusintha mankhwala kuti agwirizane ndi chibadwa cha munthu, titha kusintha zina mwa mayankhowo ndikuchepetsa zomwe zingachitike." Kupatula apo, monga kukula kwachisanu ndi chimodzi sikungakukwanireni ngati muli wamkulu wachiwiri, simankhwala onse omwe amakwanira wodwala aliyense.

Kumene Tili Panopa

Anthu ambiri-ngakhale iwo omwe sali odwala-ali ndi chidwi chofuna kudziwa zambiri zamtundu wawo komanso momwe zingayambitsire matenda awo. Kafukufuku wina waposachedwapa anasonyeza kuti 98 peresenti ya anthu amene anafunsidwawo angafune kudziwa ngati DNA yawo inasonyeza kuti pali ngozi yowonjezereka ya matenda oika moyo pachiswe. Amayi ambiri-kuphatikiza, odziwika kwambiri, Angelina Jolie-agwiritsa ntchito kuyesa kwa majini kuti awone kuopsa kwawo kwa matenda monga khansa ya m'mawere kapena yamchiberekero, ndikuchitapo kanthu kuthana ndi zoopsazi. (Mzimayi wina amagawana "Chifukwa Chake Ndalandira Mayeso a Alzheimer's.")

Ndipo machitidwe ambiri azachipatala agwiritsa ntchito chidziwitso cha DNA kale kuti apange mapulogalamu othandizira khansa komanso matenda amtima. "Chithandizo chokhudzana ndi chibadwa cha munthu chakhala chikugwiritsidwa ntchito kale komanso chothandiza, makamaka pankhani yothandizira khansa komanso matenda amtima," atero a Woodahl.

Koma mtundu wa mankhwala opangidwa ndi makonda sikunayambebe kudalira dziko lonse lapansi, ndipo Woodahl akuti zomwe zachitika m'zipatala zina zachedwa pang'onopang'ono kuposa momwe anthu ambiri amaganizira. Chifukwa chiyani? "Pali nkhawa zakuti ndi ndani amene azilipira kukayezetsa, komanso ndani angalangize opereka ma data pazoyeserera," akufotokoza. (Kodi Zolemba Zanu Zamankhwala Zamagetsi Ndi Zotetezeka Motani?)

Kwenikweni, madokotala ndi machitidwe azipatala amafunikira nthawi yochuluka kuti adziwe za sayansi. Izi zitha kukhala zotsika mtengo, ngakhale zikutsika mtengo nthawi zonse pomwe ukadaulo ukupeza zofunikira pazantchitoyo.

Zikubwera posachedwa

Momwe njira zatsopanozi zilili, njira zakuthambo zikafika pamagwiritsidwe othandiza kapena katemera. Chitsanzo chimodzi: Ofufuza a pa yunivesite ya Washington ku St. Louis posachedwapa anagwiritsa ntchito kutsatizana kwa majini poyerekezera minofu yathanzi ndi minofu ya matenda pakati pa odwala atatu omwe ali ndi melanoma. Powonetsa kusintha kwamapuloteni a wodwala aliyense, ofufuzawo adatha kupanga katemera womwe umakulitsa mphamvu ya T-cell ya odwala yakupha khansa.

Maphunziro ochulukirapo ngati ang'ono awa akukonzedwa. Ngati achita chimodzimodzi, onse omwe ali ndi khansa ya khansa amatha kulandira chithandizo chamtunduwu cha DNA posachedwa. Ichi ndi chimodzi chokha chomwe chikuchitika-pakali pano cha momwe mankhwala opangira makonda akuwongolera chisamaliro chaumoyo. (P.S: Kodi mumadziwa kuti Kupirira Masewera Kumapangitsa DNA Yanu Kukhala Yathanzi?)

Tsogolo

Mankhwala opangidwa ndi makonda posachedwa atha kupititsa patsogolo zochiritsira pachilichonse kuyambira pamavuto amisala mpaka kuwongolera ululu, atero a Woodahl. Kuthekera kwina ndikuzindikira kuchuluka kwa mankhwala osokoneza bongo kwa omwe ali ndi vuto la kupsinjika-komwe, pakadali pano, kumatsimikizira zovuta kwambiri. Zambiri zokhudzana ndi jini ziyenera kuthandiza madotolo kupereka mankhwala oyenera komanso olondola, a Woodahl akutero. Amayembekezeranso kupita patsogolo kofananako kwa mankhwala opha ululu, othandizira matenda opatsirana, komanso mankhwala osokoneza bongo amanjenje monga khunyu. Zitha kukhala zosintha kwambiri pamakampani azaumoyo, ndipo, mwamwayi, zikuwoneka ngati tikhala opindula kwambiri.
