Kodi mankhwala ochapira tsitsi ndi angakhale angelo shawa zikhoza kuyambitsa khansa?

Mu magazini Cell inalemba nkhani asayansi amene posachedwapa anachita kafukufuku latsopano. ripoti anachititsa chipwirikiti pa TV, ndipo anayamba kukambirana zoti pafupifupi onse tsiku ndi tsiku "zasayansi" kuti tigwiritse ntchito, zikhoza kuyambitsa khansa. Mwachionekere, uthenga umenewo kumwedwa ndi uzitsine monyoza, ndi pamaso kupanga mfundo iliyonse, ndendende zomwe amati olemba kuphunzira.

poizoni

Unachitikira motsogoleredwa ndi asayansi ku University Cambridge, amene anaphunzira zimakhudza thanzi la munthu akhoza kukhala ndi kalasi ngati mankhwala komanso aldehydes. onunkhiritsa ambiri aldehydes, ndipo nthawi zambiri zopezeka mpweya utsi wa magalimoto katundu kusamba, ndudu pakompyuta ndi zomangira.

Akatswiri a sayansi amanena kuti ena aldehydes Vuto ndi njira ma kukonza, choncho anaganiza kuchuluka angathe mmene carcinogenic. Gulu lolunjika pa formaldehyde ndi acetaldehyde.

Ntchito zosiyanasiyana maselo a khansa akazi yoyambitsidwa mu mankhwala amenewa, timu anayerekezera DNA alipo mwa iwo musanayambe komanso mukamaliza kukhudzana. chidwi linaperekedwa kwa losokonekera otchedwa BRCA2, chifukwa maphunziro yapita asonyeza kuti kuphwanya chirichonse cha izo kumachititsa tilinazo kuchuluka kwa mankhwala akupha ndi kusintha kapangidwe khromozomu.

Inde, onse aldehyde zinachititsa kuti kuwonongeka BRCA2. Ngati munthu mmodzi yekha ntchito buku la jini, ndi kuwonongeka ake kungachititse kuti kulephera kiyi limagwirira mapuloteni kuchira, amene ikhoza kuyambitsa matenda a khansa. N'chifukwa chake atolankhani tayenda lipoti ku zotengeka ndi kuyamba kunena kuti ambiri a aldehydes ali mu zakudya, mulole azitaya khansa.

mfundo Ofunika

Komabe, iwo anamuphonya ochepa mfundo kiyi. Choyamba, ngozi za khansa chifukwa ntchito shampu kapena wina akapuma wochepa nthunzi kuchokera ndudu pakompyuta ndi kochepa. Chachiwiri, ambiri a aldehydes si sachoka mankhwala yokumba, komanso chilengedwe.

Akatswiri salola mayina enieni milingo poizoni wa aldehydes izi, kotero kuti si bwino angati kukhala omasuka ndi zomwe zikhoza kuwonongeka kwenikweni. Osati anthu onse timakhala masinthidwe a BRCA2 jini, ndi sakumvetsabe chake.

Kodi asayansi ndalakwitsa?

Izi sizikutanthauza kuti zolakwitsa anapangidwa phunzirolo. vuto ndi zotsatira anali molakwika ndi atolankhani. phunziro kwenikweni amatipatsa lingaliro laling'ono la n'kofunika kuphunzira za chiopsezo cha ntchito aldehydes. Komabe, n'kulakwa kunena kuti ntchito shampu kapena akusamba gel osakaniza Mwachitsanzo, ndi chifukwa akuluakulu a khansa anthu. Akatswiri yekha ntchito chitsanzo kwachilengedwenso kuonetsa mmene yeniyeni mankhwala otchedwa aldehydes, zikhoza kuyambitsa khansa.
