Ngaba ishampu kunye gel ishawari kunokubangela umhlaza?

Xa Cell kwijenali wapapasha inqaku neengcaphephe kutshanje kuqhutywa isifundo esitsha. Le ngxelo yabangela inkathazeko kumajelo eendaba, baza baqalisa ukuthetha ngento yokuba phantse zonke i "chemistry 'ngemihla ukuba sisebenzise, kunokubangela umhlaza. Kucacile ukuba, umyalezo enjalo akabanjwa uwathandabuze impoxo, kwaye phambi kokuba enze naziphi na izigqibo, ukwazi kakuhle oko kuthethwa ababhali isifundo.

izinto eziyityhefu

Kuye kwabanjwa phantsi kolwalathiso izazinzulu eCambridge University, owayendifundisa nefuthe kwimpilo yabantu kunokuba iklasi lweekhemikhali kwakunye aldehydes ezinjalo. iziqholo ezininzi aldehydes, yaye ngokufuthi equlethwe neegesi zeemoto zezithuthi zemveliso webhate, icuba elektroniki kunye nezinto zokwakha.

Izazinzulu zithi ukuba ezinye aldehydes zinokuphazamisana iindlela wokulungisa zeselula, ngoko bagqiba ekubeni ubungakanani isiphumo yabo enokubakho umhlaza. Iqela swi formaldehyde kunye acetaldehyde.

Ukusebenzisa iintlobo leeseli umhlaza kwabasetyhini ayafukanywa kwezi khemikhali, iqela wathelekisa DNA ngoku kubo, ngaphambi nasemva sesichengeni. ingqalelo ekhethekileyo zahlawula isakhi ekuthiwa BRCA2, ngenxa yokuba izifundo zangaphambili lubonise ukuba nakuphi na ukwaphulwa oko kukhokelela elandileyo uvakalelo amachiza ayityhefu kunye notshintsho kubume chromosome.

Eneneni, omabini aldehyde kukhokelele kumonaka- BRCA2. Ukuba umntu ikopi enye kuphela ukusebenza zofuzo, umonakalo iya kukhokelela ukusilela indlela protein ekuphulukenwe ezingundoqo, leyo ngokumandla kusenokubangela umhlaza. Kungenxa yoko le nto eendaba ziye ingxelo ibe imvakalelo waza waqalisa ukuba babonisa ukuba abaninzi aldehydes equlethwe zokutya, kunokwandisa umngcipheko wokuhlaselwa ngumhlaza womlomo.

iinkcukacha eziphambili

Noko ke, abalahlekelwanga ezimbalwa iinkcukacha eziphambili. Okokuqala, ingozi yomhlaza ngenxa ukusetyenziswa ngeshampu okanye ukusezela neentwana umphunga ukusuka umdiza elektroniki engephi. Okwesibini, inkoliso aldehydes nto ayipheleli lokwenziwa, kodwa kokusingqongileyo.

Abaphandi kwakhona musani igama i kwizigaba ezithile yityhefu ezi aldehydes, ukuze akucaci bangaphi abaya kuba bekhuselekile kwaye kunokubangela umonakalo lokwenene. Asingabo bonke abantu basengozini wezakhi le BRCA2 zofuzo, kwaye abayiqondi kutheni.

Ngaba izazinzulu ziye wenze impazamo?

Oku akuthethi ukuba iimpazamo kwenziwa isifundo. Ingxaki yeyokuba iziphumo ziye zonakaliswa eendaba. Isifundo isinika uluvo encinane kubaluleke kangakanani na ukufunda umngcipheko usebenzisa aldehydes. Nangona kunjalo, kuba yinto embi kulowo uthi ukuba ukusetyenziswa ngeshampu okanye ishawari gel, umzekelo, sisesona sizathu lomhlaza ebantwini. Abaphandi lodwa imodeli zebhayoloji ukubonisa ethile indlela iikhemikhali ekuthiwa aldehydes, kunokubangela umhlaza.
