ʻO ka momona o nā meaʻai wahine e hoʻoikaika i ka ulu ʻana o nā pēpē ma o ka hāʻawi ʻana iā lākou ʻaʻole wale me nā waiwai waiwai waiwai, akā kākoʻo pū kekahi i ka ʻōnaehana immune ma o ka hoʻololi ʻana i ka hana o nā genes i loko o ka ʻōpū o nā pēpē, hōʻike nā ʻepekema i ka puke pai Nature.
I nā makahiki i hala iho nei, ua piʻi nui ka hoihoi i ka hānai. Ma ka puke hou loa o Nature, ua kālailai ʻo Anna Petherick, he mea kākau moʻolelo mai Sepania, i nā puke ʻepekema i loaʻa a wehewehe i ke kūlana o ka ʻike e pili ana i ka haku ʻana o ka waiū umauma a me nā pono o ka hānai ʻana.
No nā makahiki he nui, ua ʻike ʻia ka waiwai kūpono ʻole o ka waiū kanaka a me kāna kuleana nui i ka hānai ʻana i nā pēpē a me ka hoʻoikaika ʻana i ka ʻōnaehana pale o nā keiki. Hōʻike nā haʻawina mua e pili ana ka waiū umauma i ka hana o nā genes i loko o nā keʻena o ka ʻōpū i nā pēpē.
Ua hoʻohālikelike ka poʻe ʻepekema i ka ʻōlelo RNA i nā keiki hānai hānai (MM) a ua ʻike ʻia nā ʻokoʻa i ka hana o kekahi mau genes koʻikoʻi e hoʻomalu i ka hōʻike ʻana o nā mea ʻē aʻe.
ʻO ka mea hoihoi, ua ʻike ʻia aia nā ʻokoʻa ma waena o ka meaʻai a nā makuahine hānai keiki kāne a me nā kaikamahine - loaʻa i nā keikikāne ka waiū mai ko lākou mau umauma i ʻoi aku ka waiwai o nā momona a me nā protein ma mua o nā kaikamahine. Aia kekahi mau meaʻai nele loa i ka waiwai meaʻai no nā kamaliʻi i ka waiu kanaka, e lawelawe wale ana i ka ulu ʻana i ka pua kūpono o nā maʻi maʻi ʻōpū.
Mahalo i nā ʻenehana hou o ka noiʻi molecular biology a me ka noiʻi evolutionary, ʻike mākou ʻo ka waiu kanaka, ʻokoʻa ka meaʻai no nā pēpē, he mea hoʻouna i nā hōʻailona koʻikoʻi no ka ulu ʻana o nā keiki. (PAP)
