Ungalisebenzisa igazi lalo mntwana ukwenza uzive ungcono ebudaleni bakho?Wikimedia Commons Ulwelo lomzimba ngokuqondakalayo lwenza abantu babe madolo, ngakumbi xa izinto ezinjengegazi lezilwanyana zisetyenziswa kubugcisa. Kodwa ukuba igazi lomntwana osandul 'ukuzalwa linokukwenza uzive umncinci kwakhona, ungoyisa ukukhathazeka kwakho?
Oko kunokuvakala ngathi yimovie eyoyikisayo, kodwa enkosi kwiqela leenzululwazi zeYunivesithi yaseStanford Iphupha likaPeter Thiel Yokuzitofa ngegazi labantu abancinci kunokuba yinyani.
Abaphandi kwiziko leziko lase-California le-neurology bafumanise ukuba igazi elivunwe kwiintambo zeentsana Iimpembelelo ezichasene nokuguga zinamandla. Ngokukodwa, bafumanisa ukuba iprotein esegazini elincinci ibizwa ngokuba TIMP2 baneepropathi zokuhlaziya. Iziphumo zapapashwa ngoLwesithathu kulindixesha Indalo .
Iqela laseStanford, elikhokelwa ngu UGqirha Joseph Castellano , waqokelela igazi ebantwini kumanqanaba amathathu obomi ahlukeneyo-iintsana, abantu abancinci abakwiminyaka engama-22 nangaphezulu abantu abakwiminyaka yobudala engama-66. Baze batofa incindi yeplasma kwiimpuku ezazimalunga nama-50 kwiminyaka yabantu.
Iimpuku ezafumana intambo yeplasma yeentsana (eyanikelwa ngoomama abavumayo) zaziva ezona ziphumo zimangalisayo-zazikhawuleza ukufunda kwaye zikhumbula indlela enqamlezayo. Oku kungqinelana nomsebenzi owandisiweyo kwihippocampus yabo, kwingingqi yengqondo enoxanduva lokufunda kunye nenkumbulo.
Iimpuku ezazitofwe nge-twentysomethings ’plasma nazo zazinokuphucuka okuthobekileyo ekusebenzeni kwehippocampus, kodwa abo bafumana iplasma kubantu abadala ababonakalisanga kuphucuka.
I-TIMP2 isenokuba sisizathu soku- amanqanaba eprotein ancipha egazini kunye nobudala, okuthetha ukuba iplasma yomntu ngokuthe ngcembe iphulukana nezinto zayo zokubuyisela.
Le hypothesis iqinisekiswa yinto yokuba xa iimpuku ezindala zazifakwe nge-TIMP2 kuphela, babhala imisebenzi ephuculweyo ye-hippocampus kunye nokuhamba kwemaze. Ikwabuyise amandla abo okwakha iindlwane (ubuchule beempuku ezindala).
Abaphandi baseStanford abakaqiniseki ukuba kutheni i-TIMP2 ibaluleke kakhulu ekuqondeni, kodwa iyaziwa ukuthintela iqela lee-enzymes ezibizwa I-matrix metalloproteinases ezichaphazelekayo ukuqhubela phambili kwesifo se-Alzheimer's. Kananjalo, i-TIMP2 inokubakho njengonyango lwe-Alzheimer.
Ewe, ukuzisa igazi labantwana kwingxoxo kunokubangela ukuba kuvalwe ingxoxo-ividiyo evamile echaza inkqubo yeplasma yahluthwa ngabaphawuli abaye bafumanisa ukuba yonke into iyinto engathandekiyo ukuba ingayicinga.
