Gulu lofufuza motsogozedwa ndi Jo Freudenheim, katswiri wa matenda a miliri ku Yunivesite ya Buffalo, adzapatsidwa ntchito yowunikira kusiyana kwa DNA methylation pakati pa ogwiritsa ntchito ndudu zamagetsi, osuta ndi osasuta. Cholinga ndikufanizira zomwe zimachitika m'mapapo mwanga aliyense.
PHUNZIRO LOTI KUDZIWA ZAMBIRI ZOKHUDZA ZOKHUDZA ZOKHUDZA PA THUPI.
Kafukufukuyu wopangidwa ndi katswiri wa miliri wochokera ku yunivesite ya Buffalo kotero akufuna kupereka mayankho pa zotsatira za ndudu za e-fodya pa thupi. Ndizowona kuti mayankho amafunikira popeza ndudu za e-fodya zakula kwambiri ndipo Food and Drug Administration imawongolera.
Malinga ndi Jo Freudenheim, pulofesa wodziwika ku yunivesite ku Buffalo komanso wapampando wa dipatimenti ya Epidemiology and Environmental Health adati.Kugwiritsa ntchito fodya wa e-fodya kukuwonjezeka mofulumira, kuphatikizapo pakati pa achinyamata omwe sanasutepo ndudu»
Mphatso ya $100 kuchokera ku Kupewa Cancer Foundation, bungwe lokhalo lopanda phindu la ku America lodzipereka kwambiri popewa khansa komanso kuzindikira msanga. Kufufuza za zotsatira za ndudu za e-fodya ndikofunikira kwambiri chifukwa chosowa chidziwitso chokhudza thanzi la ogwiritsa ntchito.
« Pali chidwi chochuluka pakumvetsetsa momwe ndudu za e-fodya zingakhudzire thupi", Freudenheim adatero. “ A FDA alinso ndi chidwi kwambiri ndi deta yokhudzana ndi chilengedwe cha ndudu za e-fodya. Phunziroli lithandizira ku izi. »
Zomwe zimapangidwira mu e-zamadzimadzi ndi chikonga, propylene glycol ndi/kapena glycerol. Mukagwiritsidwa ntchito muzakudya ndi zodzoladzola, zinthu zomwe siziri chikonga zimawonedwa ngati zotetezeka ndi FDA. Komabe, ndizochepa zomwe zimadziwika ponena za momwe mankhwalawa angakhudzire mapapo a munthu pambuyo pokoka mpweya ndikutsatira kutentha komwe kumachitika mu ndudu ya e-fodya.

PHUNZIRO LIMENE LIMENE LIKUYENERA KUKHALA NDANI?
Pa kafukufuku woyendetsa ndegeyu, Freudenheim ndi anzawo awunika zitsanzo kuchokera m'mapapo a osuta athanzi, osasuta, komanso ogwiritsa ntchito ndudu ya e-fodya azaka zapakati pa 21 mpaka 30. Otenga nawo gawo mu kafukufukuyu adapanga njira yotchedwa bronchoscopy, ndi zitsanzo za maselo am'mapapo omwe amasonkhanitsidwa kudzera munjira yothamangitsira.
Ofufuza aphunzira zitsanzo kuti awone ngati pali kusiyana kwa DNA methylation pakati pa magulu atatuwa. Aphunzira mawanga 450 pa DNA ya minofu.
« Selo lililonse m’thupi lanu lili ndi DNA yofanana, koma mbali zina za DNAyo zimagwira ntchito zosiyanasiyana. Kusintha kwa DNA methylation kumathandiza kusiyanitsa mitundu ya maselo awa », akufotokoza Freudenheim.
Phunziro la Freudenheim lidzamangidwa pa kafukufuku wina woyendetsa ndege yemwe wangoyamba kumene Peter Shield, MD, wa Ohio State University College of Medicine, wofufuza wamkulu pa thandizo la Prevent Cancer Foundation. Cholinga chake ndi kupempha ndalama zothandizira maphunziro okulirapo.
Jo Freudenheim ali ndi chidwi cha nthawi yayitali ku DNA methylation, makamaka makamaka pa zotupa za m'mawere, pamene Peter Shields ali ndi chidziwitso chochuluka pa kafukufuku wa fodya ndi e-fodya. Agwira ntchito limodzi kwa zaka zoposa 20 kufufuza njira zopewera khansa.
