Hurdada dhinaca wanaagsan ee maskaxda

Ma aha news in xaaladda ka jirta taas oo qofka la hurda, waxay saamayn kartaa qaabka iyo dheefshiidka, laakiin soo baxday in ay saamayn weyn ku yeelataa aragtiyada iyo caafimaadka maskaxda. baaritaano dhawaan la sameeyay ayaa muujiyay in ay xidhiidh la leh awoodda maskaxda ee ay u fuliyaan shiid ku habboon, oo ay ku jiraan u qaadidda ka difaan kiimikooyin waxyeello leh. Sidaas darteed, waxaa jira qaab hurdada oo dheeraad ah oo ka yar door bidayo.

Waa maxay sababta ka wanaagsan in ay seexdaan on kooxdiisa?

Seynisyahanno ku ogaaday in hurdada aad dhinaca halkii on dhabarka ama calooshaada. Taas da'ayeen ogolaanaya jirka oo si wax ku ool ah oo dheeraad ah laga takhaluso qashinka kiimikada maskaxda. Saaxiibkiisa University of Rochester (New York) Maiken Nedergard, kuwaas oo ku qaatay tiro ka mid ah waxbarashada, Hagidda xaqiiqda xiiso leh: booskaas inta badan barriinsaday sariirta inta badan xoolaha, oo ay ku jiraan dadka deggan duur-joogta, iyo dad door bidaan in ay nastaan bulk of ceeb this gaar ah . saynisyahan waxay aaminsan tahay in xaaladda this maskaxda ugu wax ku ool ah ka daahirsanaato qashinka dheefshiidka ururtay inta lagu guda jiro xillo.

In tijaabo ay, cilmi loo isticmaalo habka ay u firfircoon-barbardhigo imaging resonance magnetic (MRI), taas oo loo ogol yahay aragtida wanaagsan oo isbedel kiimikada dhismeedka gudaha ee unugyada maskaxda kala duwan ka, gaar ahaan, waxa loogu yeero Jid glimfatichesky ah (nidaamka ah oo khamriga filter ah, ie, dheecaanka lafdhabarka oo waxaa lagu badelay dheecaan interstitial wareegsan oo dhan unugyada kale ee jirka). Tani function nafsaaniga ah lagama maarmaan u ogolaanaya in laga takhaluso qashinka iyo kiimikooyinka kale ee ku ururto maskaxda iyo in la saaro (tus, beta-amyloid iyo protein Tau). Ay badin keeni kartaa cudurka Alzheimers iyo Parkinsons.

Sida tijaabooyinka iyo tijaabo, geeddi-socodka ay ka saareen beta-amyloid gayso inta la hurdo. Laakiin sidaas maaha oo dhan. On nadiifinta xoogga saamayn ku ceeb ah, taas oo qof ama xayawaan seexdo.

Nuxurka of tijaabo ah

tijaabo ayaa la sameeyaa dadka waaweyn ee jiirka shaybaarka Hawiyaha hurdada macmal ah (kabuubyeyn) iyo amaah Mire Waqaf oo in mid ka mid ah saddex jagooyinka (dhinaca, on caloosha ama dhabarka). Markaas, daraasadda bandhigi glimfatichesky jidka maskaxda xoolaha hurdada.

Sida sharaxay by Dr. Helene Benveniste, co-author of daraasadda, kuwaas oo natiijada la daabacay ee "Neyrosayns" magazine, falanqaynta muujisay in shiid ahaa ugu waxtarka badan marka hurdo lagu arkay booska lateral. Sida uu sheegay, kuwaas oo natiijada dhici codsan in ay aadanuhu. Agtaagan hurdada dhinaca si cad u badan yahay faa'iidada badan marka la eego xagga dambe ama caloosha.

Haddii ay tani run tahay oo la xiriira dadka?

Tusaale ka mid ah "walaalo yar" waxay muujinaysaa in nuujiya (eyda, bisadaha, iyo xataa maroodi) door bidaan in ay seexdaan jidka in, inkastoo qorayaasha aan guul darreysan karaa in la ogaado in habdhaqanka caadiga ah ee xayawaanka duurjoogta ah waxaa sidoo kale loo sameeyay sarkhaansan yihiin shuruudaha badbaadada iyo, Sidaa darteed, kala duwanaan karaan ka aadanaha ah. Daraasadani waxay la sameeyay on jiirka iyo weli si buuxda uma siinayaa sababo in natiijada wareejiyo aadanaha, inkasta oo aanay ahayn sida fikrad cajiib ah.

noocyo badan oo waallida qaba waxaa la xidhiidha rabshooyin hurdo, oo ay ku jiraan dhib ku seexan. Waxaa laga helay caddaymo sii kordhaya in xanuunadan dardar kartaa khasaare xasuusta in cudurka Alzheimers. "Natiijooyinka Our siiyaan aragti cusub oo ku saabsan arrintan, taas oo muujinaysa muhiimadda ay leedahay in qaabka marka la seexdo," - ayuu ku yiri gabagabo Nedergard.
