Imithi eqondene nomuntu eyenziwe nge-DNA Ingashintsha Ukunakekelwa Kwezempilo Phakade

Wake wazizwa sengathi imiyalo kadokotela wakho ayihambisani ngempela nalokho okufunwa umzimba wakho noma okudingayo? Awu, awuwedwa. Futhi kunegagasi elisha lonke lobudokotela ekhoneni, elibhekwa "njengomuthi owenziwe waba ngowakho," osebenzisa ukulandelana kwe-DNA ukuthuthukisa izindlela zokwelapha ezakhelwe ezakhiweni zofuzo zakho ezihlukile. (Okwamanje, nazi Izindlela Ezi-8 Zokusebenzisa Ngokugculisayo Udokotela Wakho.)

Lokho kusho ukuthini: Ezimweni eziningi, okudingayo yisampula yegazi noma umlomo welebhu yokwenza ibalazwe le-DNA yakho, kusho u-Erica Woodahl, Ph.D., isazi samakhemikhali e-University of Montana. “Abantu abanesifo esifanayo abalashwa ngomuthi ofanayo banezimpendulo ezihlukene,” kuchaza uWoodahl. "Uma sikwazi ukwenza umuthi uhambisane nezakhi zofuzo zomuntu othile, singathuthukisa ezinye zalezo zimpendulo futhi sinciphise amathuba okuthi abantu bangasabeli kahle." Phela, njengoba usayizi wesithupha engeke wakulingana uma ungusayizi wesibili, akuzona zonke izindlela zokwelapha ezilingana nesiguli ngasinye.

Lapho Sikhona Manje

Abantu abaningi-ngisho nalabo abangagulanga-banesifiso sokufunda kabanzi ngezinto zabo zofuzo nokuthi zingaba kanjani nobungozi besifo sabo. Ucwaningo lwakamuva luthole ukuthi amaphesenti angama-98 alabo abahloliwe angafuna ukwazi ukuthi ngabe i-DNA yabo ikhomba yini engcupheni yokwanda kwesifo esisongela impilo. Abesifazane abaningi kufaka phakathi, odume kakhulu, u-Angelina Jolie-basebenzise ukuhlolwa kofuzo ukuhlola ubungozi bezifo ezifana nomdlavuza webele noma wesibeletho, nokuthatha izinyathelo zokubhekana nalezi zingozi. (Owesifazane oyedwa wabelana ngokuthi "Kungani Ngithole Uvivinyo Lwe-Alzheimer's.")

Futhi izinhlelo eziningi ezinkulu zokunakekelwa kwezempilo sezivele zisebenzisa imininingwane ye-DNA ukudala umdlavuza kanye nezinhlelo zokwelashwa kwezifo zenhliziyo. "Ukwelashwa okusekelwe kuzakhi zofuzo zomuntu kakade kuyasetshenziswa futhi kuyasebenza, ikakhulukazi ezindaweni zokwelapha umdlavuza kanye nokwelashwa kwezifo zenhliziyo," kusho uWoodahl.

Kepha lolu hlobo lomuthi oqondene nawe akukabi yindinganiso ezweni lonke okwamanje, futhi u-Woodahl uthi ukusetshenziswa kwezinye izinhlelo zesibhedlela kuhamba kancane kunalokho abantu abaningi emkhakheni wezokwelapha eziqondene nawe okungenzeka ukuthi bebekuqagela. Kungani? “Kunokukhathazeka ngokuthi ngubani ozokhokhela ukuhlolwa, nokuthi ngubani ozokweluleka abahlinzeki ngemininingwane yokuhlolwa,” kuchaza yena. (Aphephe Kangakanani AmaRekhodi Wakho Okhishwa Nge-elekthronikhi?)

Ngokuyisisekelo, odokotela nezinhlelo zesibhedlela badinga isikhathi esengeziwe ukuze bathole isayensi. Lokho kungaba isiphakamiso esibizayo, nakuba kuncipha ngaso sonke isikhathi njengoba ubuchwepheshe buzuza isisekelo ngezidingo zomsebenzi.

Kuyeza maduze

Njengoba lawa masu amasha nobuchwepheshe kwamukelwa, isibhakabhaka singumkhawulo uma kuziwa ekwelashweni okusebenzayo noma ekugomeni. Isibonelo esisodwa: Abaphenyi baseWashington University eSt. Ngokukhomba ukuguqulwa kwamaprotheni okuhlukile kwesiguli ngasinye, abacwaningi bakwazi ukwenza imishanguzo eyandisa amandla ama-T-cell ezibulala umdlavuza weziguli.

Izifundo eziningi ezinjengalezi ezincane zihleliwe. Uma bephumelela ngokulinganayo, bonke abaphethwe yi-melanoma bangase bathole lolu hlobo lokwelashwa okuqondene ne-DNA. Leso yisibonelo esisodwa nje esenzekayo-manje sokuthi umuthi womuntu siqu uthuthukisa kanjani ukunakekelwa kwezempilo. (P.S .: Ubuwazi ukuthi i-Endurance Sports Yenza i-DNA Yakho ibe Nempilo?)

Ikusasa

Imithi eyenziwe yaba ngeyakho kungekudala ingathuthukisa izindlela zokwelapha zayo yonke into kusuka ekuphazamisekeni kwezempilo yengqondo kuya ekuphatheni izinhlungu, kusho uWoodahl. Okunye okungahle kwenzeke ukuthola umthamo ofanele namandla ezidakamizwa kwabaphethwe ukucindezeleka-okuyinto, okwamanje, okufakazela ukuthi kunzima kakhulu. Ulwazi olusekelwe kufuzo kufanele lusize odokotela banikeze imithamo esebenza ngempumelelo, enembile, kusho uWoodahl. Ulindele intuthuko efanayo kumaphilisi ezinhlungu, ekwelashweni kwezifo ezithathelwanayo, nasezidakamizweni zezifo zemizwa ezifana nesifo sokuwa. Kungaba ushintsho olukhulu embonini yezempilo, futhi, ngenhlanhla, kuzwakala sengathi sizoba abahlomuli abakhulu kakhulu.
