Basa racho rinobudiswa mune iyo Biorxiv Preprints. Kuchengeta vacheche mumakore epakati, sezvazvinozivikanwa, zvaive nengozi zvakanyanya uye kutakura mangozi akakosha kuna amai, uye nemwana. Vakadzi vakafa kubva patapartum hutachiona, kurangarirwa kwechibereko uye zvimwe zvinonetsa, saka kutarisira kwehupenyu hwebonde kakawanda munguva idzodzo pane vapfupi pane varume.
Hazvishamisi kuti vazhinji talismans vakabatana nekuzvara, izvo zvakapa kupfeka chechi yeKaturike kune vakadzi. Pakati pavo pane zvakawanda zvinongedzo kune anonzi anonzi mabhanhire anogadzirwa kubva kune akasiyana siyana zvinhu - Silika, pepa, parchment. Muzvinyorwa zvakawanda zvakafanana, minamato yakanyorwa kuchengetedzwa kwemurume neutano hwake, kusanganisira kuchengetedzwa kwemabhiri.
Vazhinji ve "mabhandi" ana maternity "akaparadzwa mushure mekushandurwa kwechechi, saka vashoma chete ndivo vakasvika nhasi. Manyoro ekare anoratidza kuti aya mabhanhire aishandiswa pakubereka serudzi rwe "kurapwa", asi hapana humbowo hwakananga hwekupfeka mabhanhire panguva yekubereka.
Masayendisiti anobva kuCambridge, Edinburgh uye University of London (United Kingdom) akasarudza kuongorora kweioboleculy yeimwe yeiyo yakachengetedzwa "mabhanhire" anowana mhinduro chaiyo kumubvunzo uyu. Zvinokosha kuziva kuti vaongorori vakasarudza chaizvo muenzaniso, uyo wakachengetedza minyengetero chaiyo yekudzivirira kwechikadzi uye kutaurwa kwevatsvene vanosangana nevakadzi uye kubereka mwana. Mukuwedzera, icho chinoratidza kuona kuti bhandi raishandiswa chaizvo uye rakapfeka chaizvo uye rakapfeka, sezvo zvimwe zvakanyorwa uye zvifananidzo zvakadzimwa, kune mamwe madhiri mazhinji asinganzwisisike.
Pashure pokuongorora masangano anotorwa kubva kune aya masayera, masayendisiti akauya kumhedziso yekuti vanoenderana nemapuranga emunhu wePerman-aginal Fluid. Mukubatana nezvinhu zviri pamusoro, izvi zvinogona kufungwa nezvakareva kuti bhandi raishandiswa chaizvo panguva yekuzvara mwana. Vanotsvagurudza vanotenda kuti zvinhu zvakadaro zvakange zvakapfekwa zvakangofanana nebhandi rekuvimbika.
