Thaum oxidative kev nyuaj siab, cov dawb radicals ntau dhau tuaj yeem ua rau cov qauv hauv lub hlwb puas tsuaj thiab tseem ua rau cell tuag, uas yuav ua rau muaj kev pheej hmoo ntawm Parkinson's disease. Oxidative stress kuj hloov cov proteins tseem ceeb, xws li amyloid-beta peptides.
Yuav ua li cas Thaum oxidative kev nyuaj siab nce?
Ntau oxidative kev nyuaj siab ua rau muaj kev pheej hmoo ntawm kev noj qab haus huv tsis zoo , xws li kab mob plawv thiab qee yam mob qog noj ntshav. Koj lub cev xav tau kom muaj qhov sib npaug ntawm cov dawb radicals thiab antioxidants. Thaum qhov sib npaug no cuam tshuam, nws tuaj yeem ua rau oxidative stress.
Yuav ua li cas oxidative kev nyuaj siab puas hlwb?
Oxidative kev nyuaj siab tshwm sim thaum muaj qhov tsis txaus ntseeg ntawm kev tsim dawb radical thiab lub peev xwm ntawm cov hlwb kom tshem tau lawv. Piv txwv li, ntau tshaj ntawm hydroxyl radical thiab peroxynitrite tuaj yeem ua rau lipid peroxidation, yog li ua rau cov cell membranes thiab lipoproteins.
Lub luag haujlwm ntawm oxidative kev nyuaj siab yog dab tsi?
Oxidative stress tau txais kev saib xyuas raws li ib qho ntawm cov hauv paus ntsiab lus cov txheej txheem ua lub luag haujlwm rau kev txhim kho cov ntshav siabCov pa oxygen Reactive (ROS) muaj lub luag haujlwm tseem ceeb hauv homeostasis ntawm phab ntsa vascular; yog li ntawd, lawv tuaj yeem yog ib feem ntawm cov txheej txheem uas ua rau muaj ntshav siab.
Kev ntxhov siab oxidative ua rau kub siab li cas?
Ntxiv rau, nce oxidative kev ntxhov siab tuaj yeem ua rau cov endothelium puas thiab ua tsis tausendothelium-dependent vascular so thiab nce vascular contractile kev ua. Tag nrho cov teebmeem no ntawm vasculature tuaj yeem piav qhia yuav ua li cas nce oxidative kev nyuaj siab tuaj yeem ua rau kub siab.
