Chikonzero chaicho chikonzero nei tarara takarega chimwe chezvinhu zvisingazivikanwi zvikuru zve sayenzi yemazuva ano. Zvinyorwa zvakawanda zvakasiyana-siyana zvakave zvataurwa, asi chokwadi ndechokuti hapana munhu anonyatsoziva kuti nei tichishandisa chikamu chetatu chehupenyu hwedu tarara.
Pakave nekutsvakurudza kwakawanda kuratidza kuti kurara kunobatsira kusimbisa pfungwa uye kugadzirisa muviri, asi masayendisiti mazhinji anotenda kuti zviito izvi hazvitsananguri zvakakwana chinangwa chekurara, zvikurukuru kubva pakuchinja kwemaonero.
Kushandisa mararamiro edu akawanda akarara uye vanotambura kunotisvitsa kusvika kune ngozi huru, saka nyanzvi dzakawanda dzinotenda kuti panofanira kuva nechikonzero chinokurudzira nei tichirara .
Zvimwe zvitsvakurudzo zvenguva ichangopfuura, zvisinei, zvinopa hukuru hukuru kune imwe yenzira dzepamusoro dzekurara, izvo zvinoratidza kuti kurara kunokosha kubvumira uropi kuchenesa nekudzoka kubva pamabasa ezuva rapfuura.
Chimwe chidzidzo chakabudiswa mumagazini ya2013 cheScience chakabudisa pachena kuti kurara kunopa huropi mikana yekuzvichenesa pachayo. Dzidzo yacho pachayo inobatanidza kutarisa kutenderera kwemvura mumutsara wemakonzo mumuka uye kurara. Vatsvakurudzi vakanyanya kunyanya kuratidza kuti mvura inoshanduka inopinda sei mukati meglymphatic system kana nzvimbo dziri pakati peeurons . Ichi chinhu chakafanana nekurasa tsvina, kusunungura marara anokonzera masero europi paanoita mabasa anowanzoitwa.
Fluid Flow Inowedzera Mukurara kweBongo
Zvisinei, kutakura zvinhu izvi zvinosvibisa zvinoda simba guru, uye vatsvakurudzi vakafunga kuti uropi hahukwanise kutsigira mabasa aya ekuchenesa uye kuronga ruzivo rwemashoko panguva imwe chete.
Kuti aedze pfungwa iyi, munyori wekutungamira wekudzidza, Lulu Xie, akapedza makore maviri kudzidzisa mitezo kuti arara pamhando ye microscope iyo inobvumira vatsvakurudzi kuti vaone dae richifamba nemhuka inorarama.
Mushure mekuita kweEEG basa yakasimbisa kuti mbeve dzakanga dzanyarara, dhayi rebhuruya rakakonzerwa mu cerebrospinal fluid yavo.
Ihafu yeawa gare gare makonzo akasvinudzwa uye dhayi tsvuku yakabva yajowa. Nenzira iyi, vatsvakurudzi vakakwanisa kutarisa kushambadzira kwemavara ehute uye matsvuku kuburikidza neuropi. Zvavakaona ndezvokuti apo huwandu hwakawanda hwehutachiona hwakasvibira muuropi panguva yehope, kunyanya kufamba kwakanyatsoonekwa apo wakamuka.
Nzvimbo Pakati Pemajeri eBongo Anokura Mukurara
Saka nei pakanga pane mvura yakakura yakadai ichiyerera panguva dzevete dzorara kunze kwekumuka kwemhepo? Vatsvakurudzi vakacherechedzawo kuti nzvimbo dzomukati pakati pemasero europi dzakawanda zvikuru munguva dzehope, zvichibvumira kushanduka kwemvura kuchiyerera zvakasununguka. Aya mazamu akawedzerwa anenge anenge 60% panguva yokurara. Vatsvakurudzi vakawanawo apo mamwe mapuroteni akaiswa mujecha, mapuroteni akaregedzerwa nekukurumidza munguva yekurara.
Zvinogona Kuitika
"Izvi zvakawanikwa zvine zvakakosha pakurapa 'chirwere chinonyangadza' chirwere cheAlzheimer," akadaro Maiken Nedergaard, mumwe wevanyori vekudzidza. "Kunzwisisa zvakananga uye sei apo uropi hunoita kuti glymphatic system ishande uye kupedza tsvina ndiyo danho rekutanga rinotambudza mukuedza kuti zvigadzirise urongwa uhwu uye huite kuti hushande zvakajeka."
Masayendisiti ave achiziva kwenguva refu kuti mamwe maitiro ehutachiona akadai sehutementia, Alzheimer's ', uye sitiroko zvose zvinosanganiswa nekuvhiringidzika kwehope. Maererano naNedergaard, izvi zvingaratidza kuti kusagona kwekurara kunogona kuita basa rekuita mumamiriro ezvinhu akadaro. Zvino izvo vatsvakurudzi vakaona urongwa uhwu-kuchenesa, tariro yavo ndeyokuti ichaita kuti uwedzere kutsvakurudza kuti nzira iyi inoshanda sei uye iyo inogona kuita iyo inogona kutamba mumamiriro ehutano akafanana neAlzheimer's disease.
Chidzidzo chacho zvakare zvakare chinosimbisa kukosha kwehope. "Izvi zvinogona kuzarura hurukuro yakawanda kune vashandi vanochinja, avo vanoshanda panguva dzeusiku," Nedergaard akaudza Sayansi .
"Zvichida unova nokukuvara kana usingawani kurara kwako."
