LOND\u00ddN – Mnoh\u00ed \u013eudia pova\u017euj\u00fa elektronick\u00e9 cigarety za bezpe\u010dnej\u0161iu alternat\u00edvu klasick\u00e9ho faj\u010denia. Nov\u00e1 \u0161t\u00fadia v\u0161ak priniesla znepokojuj\u00face zistenia. Vedci tvrdia, \u017ee niektor\u00e9 pr\u00edchute m\u00f4\u017eu s\u00favisie\u0165 so zmenami vo fungovan\u00ed tis\u00edcok g\u00e9nov, ktor\u00e9 sa sp\u00e1jaj\u00fa s v\u00e1\u017enymi ochoreniami.<\/p>\n
Elektronick\u00e9 cigarety sa v posledn\u00fdch rokoch stali mimoriadne popul\u00e1rne najm\u00e4 medzi mlad\u00fdmi \u013eu\u010fmi. Mnoh\u00ed ich vn\u00edmaj\u00fa ako menej \u0161kodliv\u00fa alternat\u00edvu ku klasick\u00fdm cigaret\u00e1m. Vedci z University of Southern California v\u0161ak pri\u0161li so zisteniami, ktor\u00e9 vyvolali obavy medzi odborn\u00edkmi na verejn\u00e9 zdravie.<\/p>\n
V\u00fdskumn\u00edci analyzovali vzorky buniek od 83 \u013eud\u00ed vr\u00e1tane faj\u010diarov, pou\u017e\u00edvate\u013eov elektronick\u00fdch cigariet a nefaj\u010diarov. Pomocou modern\u00fdch genetick\u00fdch met\u00f3d sk\u00famali, ako vaping ovplyv\u0148uje aktivitu g\u00e9nov v organizme. V\u00fdsledky ich prekvapili.<\/p>\n
Uk\u00e1zalo sa, \u017ee pravideln\u00ed pou\u017e\u00edvatelia elektronick\u00fdch cigariet mali zmenen\u00fa aktivitu a\u017e 3 124 g\u00e9nov v porovnan\u00ed s \u013eu\u010fmi, ktor\u00ed nefaj\u010dili ani nevapovali, p\u00ed\u0161e The Sun. Mnoh\u00e9 z t\u00fdchto zmien boli spojen\u00e9 s biologick\u00fdmi procesmi, ktor\u00e9 sa v minulosti sp\u00e1jali s rakovinou, ochoreniami srdca, p\u013e\u00fac \u010di nervov\u00e9ho syst\u00e9mu. Vedci z\u00e1rove\u0148 zd\u00f4raz\u0148uj\u00fa, \u017ee \u0161t\u00fadia nedokazuje, \u017ee vaping priamo sp\u00f4sobuje rakovinu, ale upozor\u0148uje na potenci\u00e1lne rizik\u00e1.<\/p>\n

Pod\u013ea v\u00fdsledkov boli s najv\u00fdraznej\u0161\u00edmi genetick\u00fdmi zmenami spojen\u00e9 ovocn\u00e9 pr\u00edchute, najm\u00e4 mango a mel\u00f3n. Vedci zistili, \u017ee pr\u00e1ve ovocn\u00e9 n\u00e1plne ovplyv\u0148ovali pribli\u017ene 31 percent zaznamenan\u00fdch genetick\u00fdch zmien. E\u0161te v\u00fdraznej\u0161\u00ed efekt sa objavil u \u013eud\u00ed, ktor\u00ed kombinovali viacero pr\u00edchut\u00ed naraz. V tejto skupine bolo ovplyvnen\u00fdch viac ako 64 percent sledovan\u00fdch genetick\u00fdch zmien.<\/p>\n
Naopak, mentolov\u00e9 a m\u00e4tov\u00e9 pr\u00edchute vykazovali podstatne men\u0161\u00ed vplyv na g\u00e9nov\u00fa aktivitu.<\/p>\n

Vedcov prekvapilo aj \u010fal\u0161ie zistenie. V\u00e4\u010d\u0161\u00ed vplyv ne\u017e samotn\u00e1 frekvencia vapovania mali typ zariadenia a pou\u017eit\u00e9 n\u00e1plne.<\/p>\n
