Kearns - Sayre syndrome yog ib qho xwm txheej tshwm sim los ntawm qhov tsis xws luag hauv mitochondria, uas yog cov qauv hauv cov hlwb uas siv cov pa oxygen los hloov lub zog ntawm cov zaub mov mus rau hauv cov hlwb ua tau siv. Kev tshem tawm ntawm mtDNA ua rau muaj kev puas tsuaj ntawm oxidative phosphorylation thiab txo qis hauv cellular kev tsim hluav taws xob.
Tom qab ntawd, ib tus kuj tseem yuav nug tau tias, organelle dab tsi Kearns Sayre syndrome cuam tshuam?
Kearns-Sayre syndrome yog mitochondrial DNA (mtDNA) tshem tawm syndrome. Nws tshwm sim los ntawm qhov txawv txav hauv DNA ntawm cov mitochondria - cov qauv me me zoo li tus pas nrig pom nyob hauv txhua lub xov tooj ntawm lub cev uas tsim lub zog uas ua haujlwm ntawm tes.
Ib yam li ntawd, cov tsos mob tseem ceeb ntawm Kearns Sayre syndrome yog dab tsi? Cov cim thiab tsos mob ntawm Kearns-Sayre syndrome suav nrog cov hauv qab no:
- Cov leeg tsis muaj zog - Cov kab mob sib thooj myopathy, ptosis, thiab sab nraud ophthalmoplegia.
- Central nervous system (CNS) tsis ua haujlwm - Retinitis pigmentosa, cerebellar ataxia, kev paub tsis meej, cataracts, thiab encephalopathy.
Kuj Paub, puas yog Kearns Sayre syndrome ua rau neeg tuag taus?
Kearns - Sayre Syndrome feem ntau yog tshwm sim los ntawm ib leeg, kev hloov pauv loj ntawm mitochondrial DNA. Hauv Kearns - Cov tsos mob ntawm Sayre , kev mob plawv loj zuj zus tuaj ib txwm muaj thiab tuaj yeem ua tau tuag ; yog li ntawd, kev tso chaw raws sijhawm ntawm lub tshuab ua kom lub plawv tuaj yeem txuas ntxiv lub neej.
Kearns Sayre Syndrome zoo li cas?
Kearns - Sayre Syndrome (KSS) yog a tsawg neuromuscular tsis meej pem . Hauv cov teeb meem no, muaj ntau qhov txawv txav ntawm cov mitochondria puas lawm. Hauv kwv yees li 80 feem pua ntawm cov tib neeg cuam tshuam ntawm KSS, kev ntsuam xyuas yuav nthuav tawm cov khoom siv caj ces uas ploj lawm (kev tshem tawm) cuam tshuam nrog DNA tshwj xeeb hauv mitochondria (mtDNA).

Lub voj voog ntawm tes cuam tshuam li cas los ntawm kev mob qog noj ntshav?
Xaus. Mob qog noj ntshav yog tsis txheeb xyuas kev loj hlob ntawm tes. Kev hloov pauv hauv cov noob tuaj yeem ua rau mob qog noj ntshav los ntawm kev ua kom cov cell faib qis lossis cuam tshuam kev tswj hwm ib txwm muaj ntawm cov kab ke, xws li kev kaw lub voj voog ntawm tes lossis kev tuag ntawm tes. Raws li pawg loj ntawm cov qog nqaij hlav cancer loj tuaj, nws tuaj yeem tsim ua qog
Kev cuam tshuam cuam tshuam li cas rau nthwv dej?
Lub teeb yog refracted thaum nws hla lub interface los ntawm huab cua rau hauv iav uas nws txav qeeb dua. Txij li thaum lub teeb hloov pauv ntawm lub interface, lub nthwv dej ntawm lub teeb yuav tsum hloov, ib yam nkaus. Lub wavelength txo qis thaum lub teeb nkag mus rau nruab nrab thiab lub teeb yoj hloov pauv kev taw qhia
Lub ntsiab lus ntawm kev cuam tshuam thiab cuam tshuam yog dab tsi?
Feem ntau, koj yuav xav tau cuam tshuam raws li cov lus qhia lub ntsiab lus cuam tshuam rau qee yam thiab cuam tshuam rau qee yam uas tau cuam tshuam. Qhov sib txawv ntawm kev cuam tshuam thiab cuam tshuam yog li ntawd cov neeg tau pib siv 'cuam tshuam' raws li cov lus piav qhia
Dab tsi yog x cuam tshuam hauv daim ntawv nqes hav cuam tshuam?
Peb tuaj yeem siv daim ntawv nqes hav-intercept (y = mx + b). Qhov kev cuam tshuam x yog pom los ntawm kev teeb tsa y = 0, vim qhov ntawd yuav ua rau peb x-tus nqi uas cov kab hla ntawm x-axis
Alzheimer's cuam tshuam li cas ntawm daim nyias nyias ntawm tes?
Cov xovtooj ntawm tes muaj thaj tsam hu ua lipid rafts uas muaj cov roj cholesterol thiab gangliosides. Cov protein sib xyaw ua kom puas lub cell membrane thiab cuam tshuam kev sib txuas lus ntawm cov hlwb hauv lub hlwb, ua rau poob ntawm kev nco thiab kev paub txog kev ua haujlwm hauv Alzheimer's disease
