Kushandisa nzvimbo dzekofi pakurapa tsinga

Pane chido chiri kukura chekushandisa zvakare "nzvimbo dzekofi" nekuda kwezvikonzero zvakawanda, sekugadzira zvinhu zvitsva zvinogara zvakadaro, kunyanya sezvo fungidziro inoratidza kuti matani emamiriyoni matanhatu emarara ekofi anoraswa gore rega rega, mazhinji acho anokandwa mumarara, sekureva. izvo zvakaburitswa newebhusaiti Itsva.Atlas yakataurwa muEnvironmental Research.

Vatsvagiri kubva kuYunivhesiti yeTexas El Paso vakatsika nzira yakasiyana zvachose, vachitora kabhoni quantum dots (CACQD) kubva pachigadziko, iyo inogona kuve nekwaniso yekudzivirira masero ehuropi kubva mukurwiswa kwehutachiona hunogona kuisa hwaro hwechirwere cheurourodegenerative.

Nekuda kwake, muongorori anotungamira Jyotish Kumar akati: "Caffeic acid-based carbon quantum dots ine mukana wekushandura mukurapa kweurourodegenerative kusagadzikana."

Kurapa pasina migumisiro yakaipa

Mumasero samples, vaongorori vakawana kuti CACQD inochera kana kuvharira radicals emahara uye inodzivirira kuunganidzwa kweamyloid-kugadzira mapuroteni.

Kunyanya kukosha, haparatidzike kunge paine mhedzisiro yakaipa pamaseru. Nokudaro, kana migumisiro yekudzidza inogona kushandiswa kuwana kurapa kwekudzivirira, zvingave zvichiita kuti chirwere chirege kukura pamberi pemakiriniki ematanho.

Pamutengo unokodzera ruzhinji rwevarwere

"Zvakakosha kurapa zvirwere izvi zvisati zvasvika pachipatara," akadaro Mahesh Narayan, purofesa paYunivhesiti yeTexas, achitsanangura kuti chinangwa chekudzidza ndechekutsvaga mhinduro inogona kubatsira kurapa mamiriro ezvinhu nemutengo unogadziriswa. nhamba hurusa inobvira yevarwere.

Caffeic acid

Caffeic acid inhengo ye polyphenol, inozivikanwa neiyo antioxidant zvimiro, iyo inogona zvakare kupinda mune iyo yakakosha yeropa-brain barriers, iyo yakakosha pakupa kuchengetedzwa kweserura kune iyo saiti inoida.

Zvakare kuve sosi yakagadzikana yecaffeic acid, CACQD inogadzirwa kuburikidza neyakagadzikana "green chemistry". Ikofi yepasi "yakabikwa" pa 93 ° C kwemaawa mana, kuitira kuti idzoke zvakare mu caffeic acid carbon skeleton yeCACQD. Tichifunga nezvehuwandu hwemarara ekofi anoraswa gore rega, iyo sosi zvinhu inopa kusimudzira uye scalability.

Yechipiri yerudzi rwayo

Kunyangwe zvichiri mazuva ekutanga, timu yevaongorori inotarisira kuti kumwe kutsvagisa kuchasimbisa kuyedza kwekutanga, uye kuti rimwe zuva, chimwe chinhu chiri nyore se "nzvimbo yekofi" chinogona kupa huropi hwemunhu nhovo isingaoneki yekudzivirira kubva kune isiri-genetic neurodegenerative zvirwere. .

Chidzidzo chacho chechipiri cherudzi rwayo mumwedzi ichangopfuura, iyo inowana bhenefiti inoshamisa yehutano hwehuropi kubva kune zvigadzirwa zvekofi. MunaGunyana, vaongorori veJapan vakacherekedza komboni inowanikwa mugirinhi bhinzi yekofi, inonzi tragonelin, inoratidza mhedzisiro inovimbisa mukubatsira kuchengetedza ndangariro nekuziva basa muhuropi hwekuchembera.
