Kev ntxhov siab Oxidative tuaj yeem ntsuas tsis ncaj los ntawm ntsuas qib DNA / RNA kev puas tsuaj, lipid peroxidation, thiab protein oxidation / nitration, es tsis yog ntsuas ncaj qha ntawm cov pa oxygen reactive. Cov cim oxidative kev ntxhov siab no muaj kev ruaj khov dua li cov pa oxygen reactive.
Koj ua li cas kuaj rau oxidative stress?
Lub xub ntiag ntawm oxidative kev nyuaj siab yuav raug sim nyob rau hauv ib qho ntawm peb txoj kev: (1) ntsuas ncaj qha ntawm ROS; (2) Kev ntsuas qhov tshwm sim ntawm kev puas tsuaj rau biomolecules; thiab (3) nrhiav pom cov tshuaj antioxidant.
Qhov ntsuas ntawm oxidative kev nyuaj siab yog dab tsi?
Kev tsim cov superoxide radical (O2(•-)) tau ntsuas raws li qhov ntsuas ntawm cov pa oxygen reactive ntau lawm; lipid peroxidation (TBARS) thiab cov qib protein carbonyl tau suav tias yog cov cim ntawm kev puas tsuaj oxidative, thiab kev ua haujlwm ntawm antioxidant enzymes superoxide dismutase (SOD), catalase (CAT), glutathione …
Dab tsi yog oxidative stress biomarkers?
Biomarkers ntawm oxidative stress. Biomarkers ntawm oxidative kev nyuaj siab tuaj yeem raug cais raws li molecules uas tau hloov kho los ntawm kev cuam tshuam nrog ROS hauv microenvironment; thiab cov molecules ntawm cov kab mob antioxidant uas hloov pauv hauv cov lus teb rau kev ntxhov siab redox.
Koj ntsuas ROS li cas?
Cov qib intracellular ntawm ROS tuaj yeem ntsuas tau los ntawm flow cytometry siv dihydrofluorescein diacetate (DCFH) txhawm rau txheeb xyuas cov kab mob hauv cov cellular hydrogen peroxide radicals. Cov xim no yog oxidized rau cov fluorescent derivative dichlorofluorescein (DCF), uas tau kuaj pom los ntawm kev siv cov flow cytometer [46, 47, 48, 82].

Ntsuas qhov ntsuas qhov ntsuas li cas?
Tus odometer yog ib qho cuab yeej siv rau ntsuas qhov kev ncua deb ntawm lub tsheb. Lub odometer feem ntau yog nyob rau hauv lub tsheb lub dashboard. Lo lus "odometer" yog muab los ntawm ob lo lus Greek lub ntsiab lus thiab kev ntsuas .
Dab tsi yog kev ntsuas ntsuas ntsuas?
Metrology yog kev tshawb fawb txog kev ntsuas. Nws tsim kom muaj kev nkag siab zoo ntawm cov units, tseem ceeb hauv kev sib txuas ntawm tib neeg cov dej num. Niaj hnub nimno metrology muaj nws cov hauv paus hniav nyob rau hauv lub Fabkis Revolution txoj kev nom kev tswv kev txhawb nqa rau standardize units nyob rau hauv Fabkis, thaum ib tug ntev tus qauv coj los ntawm ib tug natural qhov chaw tau npaj.
Yuav ntsuas ntsuas ntsuas ntsuas li cas?
Ib lub ntsuas hluav taws xob muaj peev xwm ntsuas tus nqi ntawm cov khoom tawg tag nrho (TDS) hauv cov tshuaj, hauv cov khoom ntawm ib lab (ppm) lossis milligrams ib liter. Tus qauv kev sib raug zoo ntawm TDS kev ntsuas ntawm kev daws teeb meem thiab kev ntsuas kev ntsuas yog:
Los ntawm oxidative kev nyuaj siab?
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 lub ntsuas ntsuas ntsuas digital yuav dov?
Cov tsheb digital odometers tuaj yeem ua tau "dov rov qab" los ntawm kev hloov lub tsheb lub rooj tsav xwm thiab kho cov kab tsheb kauj vab kom nyeem tus lej twg koj muab tso rau hauv. … Txo lossis thim rov qab lub tsheb mileage tuaj yeem ua rau lub tsheb zoo li nws tau siv tsawg dua li qhov nws muaj, ua rau nws tus nqi nce ntxiv .
