(Txhua tus paub kab mob yav dhau los, xws li kab mob thiab kab mob, muaj cov nucleic acids, uas ua rau lawv rov tsim dua tshiab.) prion qhov kev xav piav qhia vim li cas tus neeg kis tus kab mob txawv txav tuaj yeem tiv taus hluav taws xob ultraviolet, uas ua rau tawg cov kua qaub nucleic, tab sis muaj cov tshuaj uas cuam tshuam rau cov protein.
Xav txog qhov no, vim li cas thiaj muaj prions nyob?
Hauv tib neeg, cov thawj coj tau raug txheeb xyuas tias yog ua rau tus mob Creutzfeldt-Jakob tuag taus (tib neeg tus kab mob vwm vwm), thiab cov kws tshawb fawb xav tias lawv tau ua ntau lwm yam kev mob hlwb tsis zoo, suav nrog Alzheimer's, Huntington's, thiab Parkinson's.
Ib yam nkaus, vim li cas prions txaus ntshai? Prions yog cov kab mob sib kis uas tsis tau pom dua uas ua rau pab pawg ntawm cov kab mob tuag taus neurodegenerative los ntawm cov txheej txheem tshiab. Lawv yog cov kis tau yooj yim uas tsis muaj cov nucleic acid. Vim lawv cov yam ntxwv zoo ib yam, Prions tawm raws li qhov muaj peev xwm txaus ntshai txij li lawv tuaj yeem siv los tsim cov riam phom zoo li no.
Ib yam li ntawd, puas muaj prions zoo?
Prions tuaj yeem dhau ntawm cov txiaj ntsig zoo, kev tshawb nrhiav pom. Cov kws tshawb fawb tau pom ze li ntawm 50 pab tau prions hauv cov poov xab thiab cov protein sib piv hauv tib neeg, tawm tswv yim tias hom protein uas txaus ntshai no tuaj yeem txhawb txoj sia thiab ua lub luag haujlwm hauv kev hloov pauv.
Koj yuav tua prions li cas?
Rau rhuav tshem a prion nws yuav tsum tau denatured rau lub ntsiab lus tias nws tsis tuaj yeem ua rau cov protein ib txwm tsis raug. Kev tiv thaiv cua sov rau ob peb teev ntawm qhov kub siab heev (900 ° F thiab siab dua) yuav ntseeg tau rhuav tshem a prion.

Vim li cas peb xav tau cov poov tshuaj hauv peb lub hlwb?
Potassium yog ib qho tseem ceeb ntawm cov zaub mov hauv lub cev. Nws pab tswj cov kua dej sib npaug, cov leeg nqaij thiab cov paj hlwb. Dab tsi ntxiv, kev noj zaub mov muaj poov tshuaj ntau yuav pab txo cov ntshav siab thiab khaws dej, tiv thaiv mob stroke thiab tiv thaiv pob txha thiab pob zeb hauv raum
Vim li cas peb lub qhov ntswg khiav thaum peb quaj?
Koj quaj: Thaum koj quaj, kua muag tawm ntawm cov qog kua muag hauv qab koj daim tawv muag thiab ntws los ntawm cov kua muag uas khoob rau hauv koj lub qhov ntswg. Cov kua muag sib xyaw nrog cov hnoos qeev nyob ntawd thiab koj lub qhov ntswg khiav. Tab sis cov ntshav ntxiv no ua rau cov kua ntau ntxiv
Peb yog vim li cas vim li cas lub cell faib?
Nov yog cov laj thawj vim li cas cov cell faib. Vim li cas 1: Mitosis thiab meiosis yog cov txheej txheem tseem ceeb. Vim li cas 2: Cell faib rau lub cev kev loj hlob thiab kev loj hlob. Yog vim li cas 3: Cov cell faib los kho peb lub cev. Kev faib tawm ntawm tes yog qhov tseem ceeb rau peb lub cev kev loj hlob thiab kev loj hlob
Vim li cas peb thiaj li muaj kev ncaj ncees hauv Kev Sib Tham?
Kev coj ncaj ncees txiav txim siab xaiv. Hauv kev qhuab qhia, kev coj ncaj ncees qhia txog qhov xwm txheej thiab kev coj ua los ntawm tus kws pab tswv yim. Los ntawm qhov xwm txheej ntawm txoj haujlwm, cov kws pab tswv yim yuav tsum ua kom tau txais txiaj ntsig zoo tshaj plaws ntawm lawv cov neeg siv khoom, txhawb cov hom phiaj ntawm cov neeg siv khoom, tiv thaiv cov neeg siv khoom txoj cai, ua kom zoo tshaj plaws thiab txo qis kev puas tsuaj (Stein, 1990)
Vim li cas peb yuav tsum zom peb cov zaub mov?
Kev zom zaub mov yog qhov tseem ceeb rau kev zom cov zaub mov rau hauv cov khoom noj, uas lub cev siv rau lub zog, kev loj hlob, thiab kho cell. Cov zaub mov thiab dej haus yuav tsum tau hloov mus rau hauv me me molecules ntawm cov as-ham ua ntej cov ntshav absorbs lawv thiab nqa mus rau cov hlwb thoob plaws hauv lub cev
