Shkenc\u00ebtar\u00ebt besojn\u00eb se mund t\u00eb ken\u00eb zbuluar pse stresi i b\u00ebn flok\u00ebt t\u00eb zbardhen dhe m\u00ebnyr\u00ebn e mundshme p\u00ebr ta ndaluar k\u00ebt\u00eb t\u00eb ndodh\u00eb.<\/span><\/p>\n

N\u00eb eksperimentet mbi minjt\u00eb, u zbulua se qelizat staminale q\u00eb kontrollojn\u00eb ngjyr\u00ebn e l\u00ebkur\u00ebs dhe flok\u00ebve u d\u00ebmtuan pas stresit t\u00eb fort\u00eb.<\/span><\/p>\n

Minjt\u00eb me g\u00ebzof t\u00eb err\u00ebt u zbardh\u00ebn plot\u00ebsisht brenda disa jav\u00ebsh t\u00eb eksperimentit. Studiuesit amerikan\u00eb dhe brazilian\u00eb q\u00eb kryen k\u00ebt\u00eb hulumtim, thon\u00eb se kjo rrug\u00eb vlen t\u00eb eksplorohet m\u00eb tej p\u00ebr t\u00eb zhvilluar nj\u00eb ila\u00e7 q\u00eb parandalon humbjen e ngjyr\u00ebs s\u00eb flok\u00ebve nga plakja.<\/span><\/p>\n

Burrat dhe grat\u00eb mund t\u00eb b\u00ebhen me thinja nga mesi i t\u00eb 30-ave. Kjo edhe pse varet kryesisht nga procesi natyror i plakjes dhe gjenet, stresi gjithashtu mund t\u00eb luaj\u00eb nj\u00eb rol.<\/span><\/p>\n

Por shkenc\u00ebtar\u00ebt nuk e kishin t\u00eb qart\u00eb se si stresi ndikon n\u00eb qimet n\u00eb kokat tona.<\/span><\/p>\n

Si\u00e7 shkruan BBC<\/a><\/span>, studiuesit nga Universitetet e Sao Paulos n\u00eb Brazil dhe t\u00eb Harvardit, besojn\u00eb se efektet ishin t\u00eb lidhura me qelizat burimore t\u00eb melanociteve, t\u00eb cilat prodhojn\u00eb melanin\u00ebn dhe jan\u00eb p\u00ebrgjegj\u00ebse p\u00ebr flok\u00ebt dhe ngjyr\u00ebn e l\u00ebkur\u00ebs.<\/span><\/p>\n

Dhe nd\u00ebrsa kryenin eksperimente mbi minj, ata gjet\u00ebn prova se ky ishte rasti.<\/span><\/p>\n

“Tani e dim\u00eb me siguri q\u00eb stresi \u00ebsht\u00eb p\u00ebrgjegj\u00ebs p\u00ebr k\u00ebt\u00eb ndryshim specifik t\u00eb l\u00ebkur\u00ebs dhe flok\u00ebve tuaj, dhe m\u00ebnyr\u00ebn se si funksionojn\u00eb.”-<\/em>\u00a0thot\u00eb Prof Ya-Cieh Hsu, autor i hulumtimit nga Universiteti i Harvardit.<\/span><\/p>\n

‘D\u00ebmtimi \u00ebsht\u00eb i p\u00ebrhersh\u00ebm’<\/span><\/strong><\/p>\n

Dhimbja tek minjt\u00eb shkaktoi lirimin e adrenalin\u00ebs dhe kortizolit, duke i b\u00ebr\u00eb zemrat e tyre t\u00eb rrahin m\u00eb shpejt dhe presionin e gjakut t\u00eb rritet, duke ndikuar n\u00eb sistemin nervor dhe duke shkaktuar stres akut.<\/span><\/p>\n

Ky proces m\u00eb pas shpejtoi shterimin e qelizave burimore q\u00eb prodhuan melanin\u00eb n\u00eb gj\u00ebndrat e flok\u00ebve.<\/span><\/p>\n

“Un\u00eb prisja q\u00eb stresi t\u00eb ishte i keq p\u00ebr trupin.”<\/em>– tha Prof Hsu. “Por ndikimi i d\u00ebmsh\u00ebm i stresit q\u00eb zbuluam ishte p\u00ebrtej asaj q\u00eb imagjinoja. Pas vet\u00ebm disa dit\u00ebsh, t\u00eb gjitha qelizat burimore t\u00eb rigjenerimit t\u00eb pigmenteve u humb\u00ebn. Sapo t\u00eb jen\u00eb zhdukur, nuk mund t\u00eb rigjeneroni m\u00eb pigmentin – d\u00ebmi \u00ebsht\u00eb i p\u00ebrhersh\u00ebm”.<\/em><\/span><\/p>\n

\"\"<\/a><\/p>\n

N\u00eb nj\u00eb eksperiment tjet\u00ebr, studiuesit zbuluan se mund t\u00eb bllokonin ndryshimet duke u dh\u00ebn\u00eb minjve nj\u00eb medicament anti-hipertension, i cili trajton presionin e lart\u00eb t\u00eb gjakut.<\/span><\/p>\n

Dhe duke krahasuar gjenet e minjve q\u00eb ishin n\u00eb dhimbje me minjt\u00eb e tjer\u00eb, ata mund t\u00eb identifikojn\u00eb protein\u00ebn e p\u00ebrfshir\u00eb n\u00eb shkaktimin e d\u00ebmtimit t\u00eb qelizave burimore nga stresi.<\/span><\/p>\n

Kur kjo protein, kinaza e varur nga ciklina (CDK) – u mbajt n\u00ebn kontroll, trajtimi gjithashtu parandaloi nj\u00eb ndryshim n\u00eb ngjyr\u00ebn e g\u00ebzofit t\u00eb tyre.<\/span><\/p>\n

Kjo e l\u00eb der\u00ebn t\u00eb hapur p\u00ebr shkenc\u00ebtar\u00ebt p\u00ebr t\u00eb ndihmuar n\u00eb vonimin e shfaqjes s\u00eb flok\u00ebve gri duke synuar nj\u00eb ila\u00e7.<\/span><\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"
