Pamene udzudzu ukukula kuti usagwirizane ndi mankhwala ophera tizilombo, asayansi apeza njira zochepetsera kuberekana kwawo.

Ndi chidziwitso chatsopanochi, ofufuza ali ndi poyambira polimbikitsa kuwongolera dziko lonse lapansikuchuluka kwa udzudzu.
Gulu la asayansi ochokera ku Virginia Tech linafalitsa zotsatira za kafukufuku wawo wa mahomoni a achinyamata (chizindikiro cha mankhwala chofunikira kwambiri pakubereka udzudzu) m'nkhani yofalitsidwa mu magazini ya Proceedings of the National Academy of Sciences.
Kale, ofufuza ankakhulupirira kuti ma receptor awiri osiyana anali ofunikira kuti mahomoni a achinyamata agwire ntchito. Anazindikira kuti metopron tolerance receptor (MET) ndi imodzi mwa izo, koma receptor inayo ikadali chinsinsi.
Wofufuza wamkulu Zhu Jinsong adapeza kuti MET imagwira ntchito mkati mwa maselo komanso pa nembanemba ya selo. Njira zamakono zojambulira zithunzi zimasonyeza kuti zimathandiza kuwongolera kukula, kukhwima, komanso kupangika kwa ma ovate pambuyo pake.
Ofufuzawo ataletsa ntchito ya MET pamalo ena, kubereka kwa udzudzu kunachepa kwambiri.
Mu chikalata chomwe adalengeza kwa atolankhani, Zhu adati: "Udzudzu wachikazi uyenera kugawa mphamvu ndi michere yawo mosamala kuti uyikire mazira, ndipo ngati izi zasokonekera, mphamvu yawo yoberekera imachepa."
Zomwe zapezekazi zingapereke njira ina yothandiza kwambiri m'malo mwa mankhwala ophera tizilombo amakono. Mankhwala ophera tizilombo achikhalidwe amagwira ntchito polimbana ndi mitsempha ya udzudzu, koma udzudzu pang'onopang'ono umakhala wolimbana ndi mankhwala amenewa. Kuphatikiza apo, mankhwala ophera tizilombowa amatha kuwononga tizilombo tina.
Zhu anati: “Cholinga chathu sikuti ndi kungowongolera kuchuluka kwa udzudzu, komanso kupeza njira zenizeni zochepetsera mphamvu zake pa tizilombo topindulitsa.”
Pamene madera ambiri padziko lonse lapansi akukumana ndi nyengo yotentha komanso yonyowa yomwe imalola kuti udzudzu ubereke, ofufuza akufufuza njira zatsopano zopewera ndi kuthana ndi matendawa. Kuchuluka koopsa komwe matenda a dengue akufalikira kumadera atsopano n'kofunikira kwambiri, zomwe zikusonyeza kufunika kopewa ndi kuletsa matendawa.
Kachilombo ka Zika ndi malungo achikasu ndi matenda ena omwe ofufuza amawakonda. Kafukufukuyu akuyang'ana kwambiri udzudzu wa Aedes aegypti, womwe ndi woyambitsa malungo achikasu.
Chochititsa chidwi n'chakuti, monga momwe Zhu akunenera, zomwe apeza zitha kugwiritsidwa ntchito pa zinthu zambiri osati udzudzu wokha. Ofufuza ena amakhulupirira kuti njira yomweyi ingagwiritsidwe ntchito pa tizilombo tina. Ngati njira zofananazi zingagwiritsidwe ntchito polimbana ndi tizilombo taulimi, kafukufuku wa gululi adzakhala wopindulitsa kwambiri.
Kafukufuku wowonjezereka tsopano akufunika zotsatira izi zisanagwiritsidwe ntchito poletsa kuswana kwa udzudzu.
Gulu lofufuza likugwira ntchito kuti limvetse bwino njira ndi momwe MET imagwirira ntchito. Akufufuza ngati kusokoneza MET kungalepheretse kubereka popanda kubweretsa zotsatira zina zoipa.
Zhu anamaliza ndi kuti: “Ngati tikufuna kupanga njira zothanirana ndi udzudzu zogwira mtima komanso zosamalira chilengedwe, tiyenera kumvetsetsa makhalidwe a udzudzu pamlingo wa mamolekyu.”
Lembetsani ku nkhani zaulere za TCD kuti mulandire malangizo othandiza, upangiri wothandiza, komanso mwayi wopambana $5,000 pa ntchito yokonzanso nyumba. Kuti muwone nkhani zina ngati izi, sinthani zomwe mumakonda pa Google apa.
