ʻAʻole ʻike ka hapa nui o ka poʻe i kēia, akā maʻi kekahi poʻemetala.Wahi a ka ʻike hope i paʻi ʻia ma kahi ʻatikala hou, he ʻumi pākēneka o ka poʻe Kelemania i maʻi i ka nickel.
Akā hoʻohana nā lāʻau lapaʻau i ka nickel.Ke hoʻohana nui ʻia nei nā ʻāpana nickel-titanium ma ke ʻano he mau mea no nā implants cardiovascular ma nā kaʻina hana invasive liʻiliʻi, a ma hope o ka hoʻokomo ʻana, hoʻokuʻu kēia mau mea hoʻohui i nā nickel liʻiliʻi ma muli o ka corrosion.He pilikia anei?
ʻO kahi hui o nā mea noiʻi mai Jena, Prof. Rettenmayr a me Kauka Andreas Undis, hōʻike i nā uea i hana ʻia mai kahi nickel-titanium alloy e hoʻopuka i ka nickel liʻiliʻi loa, ʻoiai i nā manawa lōʻihi.He mau lā wale nō ka manawa hoʻāʻo no ka hoʻokuʻu ʻana metala, e like me ke koi ʻia e ke aupuni no ka ʻae ʻia ʻana o ka lāʻau lapaʻau, akā ua nānā ka hui noiʻi o Jena i ka hoʻokuʻu ʻia ʻana o ka nickel no ʻewalu mahina.
ʻO ka mea o ke aʻo ʻana he uea lahilahi i hana ʻia me kahi alloy nickel-titanium superelastic, i hoʻohana ʻia, no ka laʻana, ma ke ʻano o ka occluder (he mau lāʻau lapaʻau kēia i hoʻohana ʻia e hoʻoponopono i kahi defect septal naʻau).ʻO ka occluder ka mea maʻamau i ʻelua uea liʻiliʻimakaʻu"umbrellas" e pili ana i ka nui o ke kālā euro.Hiki ke huki ʻia ka superelastic implant i loko o kahi uwea lahilahi a laila hiki ke hoʻokomo ʻia i loko o kahi catheter cardiac."Ma kēia ala, hiki ke kau ʻia ka occluder me kahi kaʻina hana liʻiliʻi loa," wahi a Undisch.ʻO ke kūpono, e noho ka implant i ka mea maʻi no nā makahiki a i ʻole mau makahiki.
Occluder i hana ʻia me ka nickel-titanium alloy.Hoʻohana ʻia kēia mau lāʻau lapaʻau e hoʻoponopono i kahi septum puʻuwai hemahema.Kiʻi: Kiʻi: Jan-Peter Kasper/BSS.
Ua makemake ʻo Undis a me ka haumāna kauka ʻo Katarina Freiberg e ʻike i ka mea i loaʻa i ka uwea nickel-titanium i kēia manawa.Hāʻawi lākou i nā laʻana uea me nā ʻano hana mechanical a me ka wela i ka wai ultrapure.A laila hoʻāʻo lākou i ka hoʻokuʻu nickel e pili ana i nā manawa manawa i koho mua ʻia.
"ʻAʻole kēia he mea koʻikoʻi," wahi a Undish, "no ka mea maʻamau ka ʻike ʻana o ka metala i hoʻokuʻu ʻia ma ka palena o ka ʻike.", lanakila i ka hoʻomohala ʻana i kahi kaʻina hana hoʻāʻo ikaika no ke ana ʻana i ke kaʻina hana hoʻokuʻu nickel.
"Ma keʻano laulā, i nā lā mua a me nā pule, e pili ana i ka mālama muaʻana o ka mea, hiki ke hoʻokuʻuʻia ka nui o ka nickel," i hōʻuluʻuluʻo Undisch i nā hopena.Wahi a nā mea ʻepekema waiwai, ʻo kēia ma muli o ka ukana mechanical ma ka implant i ka wā o ka hana.“Hoʻopau ka deformation i ka ʻāpana lahilahi o ka oxide e uhi ana i ka mea.ʻO ka hopena he hoʻonui i ka muanikelahoʻōla hou."ʻO ka nickel mākou e komo ai i ka nui o kēlā me kēia lā.
Ma ka ʻepekema 2.0, he poʻe nūpepa ka poʻe ʻepekema, ʻaʻohe manaʻo politika a i ʻole ka mana hoʻoponopono.ʻAʻole hiki iā mākou ke hana wale i kēia, no laila e ʻoluʻolu e hana i kāu ʻāpana.
He waiwai ʻole mākou, ʻĀpana 501(c)(3) ʻoihana nūhou ʻepekema nāna e hoʻonaʻauao ma mua o 300 miliona mau kānaka.
Hiki iā ʻoe ke kōkua i ka hāʻawi ʻana i ka hāʻawi ʻauhau ʻole i kēia lā a e hele kāu hāʻawi 100% i kā mākou papahana, ʻaʻohe uku a i ʻole keʻena.
