Umsebenzi ushicilelwa kuma-biolyxiv reaprints. Ingane ngeNkathi Ephakathi, njengoba yaziwa, yayiyingozi kakhulu futhi yayinezingozi ezinkulu zomama, kanye nengane. Abesifazane babulawa ngenxa yokutheleleka kwe-postpartum, ukukhunjulwa kwesibeletho nezinye izinkinga, ngakho-ke isikhathi sokuphila sobulili obuhle ngalezo zikhathi sasifushane kakhulu kunabesilisa.
Akumangazi ukuthi ama-talissans amaningi axhumene nokuzalwa kwengane, okwakunikezela ukugqoka isonto lamaKatolika kwabesifazane. Phakathi kwazo kunezinkomba eziningi kumabhande okuzalwa azenzelwa izinto ezahlukahlukene - usilika, iphepha, isikhumba. Ezithombeni eziningi ezifanayo, imikhuleko ilotshwe ekuvikelweni komuntu nempilo yakhe, kufaka phakathi ukuvikelwa kokuzalwa.
Iningi le- "maternity burtts" labhujiswa ngemuva kweNguquko yebandla, ngakho-ke inani elincane lifika kulolu suku. Imibhalo yesandla yasendulo ikhombisa ukuthi amabhande asetshenziswa ngesikhathi sokubeletha njengohlobo "lokwelashwa", kepha abukho ubufakazi obuqondile bokugqoka amabhande ngesikhathi sokuzala izingane.
Ososayensi abavela eCambridge, eDinburgh naseYunivesithi yaseLondon (United Kingdom) banquma ukubamba ukuhlaziywa kwe-biomolecular kwenye yamabhande agcinwe "agciniwe" futhi uthole impendulo ngqo kulo mbuzo. Kuyaphawuleka ukuthi abacwaningi bakhethe ngqo lesi sampula, esasigcina imithandazo ethile ukuvikela kowesifazane nokukhuluma ngabangcwele abahambisana nabesifazane kanye nokuzalwa kwengane. Ngaphezu kwalokho, kunobufakazi obubonakele bokuthi ibhande lalisetshenziswa ngempela futhi ligqoke, ngoba eminye imibhalo isusiwe, kukhona namabala amaningi endabuko engaqondakali.
Ngemuva kokuhlaziya amasampula athathwe kulezi zindawo, ososayensi bafinyelela esiphethweni sokuthi bavumelana namaprotheni omuntu woketshezi lwesitho sangasese sowesifazane. Ngokubambisana namaqiniso angenhla, lokhu kungabhekwa njengobufakazi bokuthi ibhande lalisetshenziswa ngempela ngesikhathi sokuzalwa kwengane. Abaphenyi bakholelwa ukuthi izinto ezinjalo bezigqokwa ngokufana nebhande lokuthembeka.
