Rau kev tshawb fawb ntawm kev txav tsis zoo, stereology tuaj yeem siv tau los ua ntaub ntawv hloov pauv pathological lossis poob ntawm cov hlwb lossis innervation hauv kev sim raug mob ua qauv. Ua tib zoo xyuas kom muaj nuj nqis los ntawm cov kev tshawb fawb no tuaj yeem muab cov ntaub ntawv ntau dua li cov lus piav qhia zoo lossis ib nrab ntawm ib leeg.
Vim li cas stereology tseem ceeb?
Stereology yog ib txoj hauv kev siv random, systematic sampling los muab cov ntaub ntawv tsis ncaj ncees thiab ntau ntau. Nws yog ib qho tseem ceeb thiab muaj txiaj ntsig zoo hauv ntau daim ntawv thov ntawm microscopy (xws li petrography, cov ntaub ntawv tshawb fawb, thiab biosciences suav nrog histology, pob txha thiab neuroanatomy).
Lub ntsiab lus ntawm kev siv tshuaj yog dab tsi?
: ib ceg ntawm kev tshawb fawb txog kev cuam tshuam txog peb qhov khoom ntawm cov khoom lossis qhov teeb meem ib txwm pom ob-dimensionally.
Yam stereology ua haujlwm li cas?
Cov txheej txheem Stereology tso cai rau kev piav qhia ntau npaum li cas ntawm cov khoom 3D yuav tsum tau ua los ntawm 2D ntsuas. Qhov no ua tiav los ntawm kev tsim Z-pem ntawm 2D cov duab txhawm rau tsim cov qauv 3D (West li al., 1991; West, 2012a).
Tus qauv tsim raws li kev xav yog dab tsi?
Kev tsim qauv tsim qauv muab cov cuab yeej kom tau txais qhov tseeb, meej cov ntaub ntawv muaj nuj nqis los ntawm cov ntaub so ntswg. … Nws txawv ntawm lwm txoj hauv kev morphometric raws li kev txheeb xyuas cov ntaub so ntswg los ntawm kev muab kev kwv yees uas siv tau,peb-dimensional tiag tiag, thiab xa mus rau tag nrho lub cev.

Thaum twg siv los yog tsis siv?
Ib leeg: ib leeg txhais tau tias "ib ntawm ob"; tsis txhais hais tias "tsis muaj ntawm ob." Siv cov lus qhia ib leeg. Ib yam ua ke nrog lossis; tsis yog ua ke nrog los yog. Koj hais kuv los tsis yog kuv thiab? Tsis yog grammatically tseeb.
Thaum twg siv i.e. thiab thaum twg siv xws li?
I.e. yog ib qho luv luv rau kab lus id est, uas txhais tau tias "uas yog." I.e. yog siv los rov hais dua ib yam dab tsi uas tau hais yav dhau los txhawm rau kom meej nws lub ntsiab lus. E.g. luv luv rau exempli gratia, uas txhais tau tias "
Thaum twg siv polyacrylamide thiab thaum twg agarose?
Agarose gels siv nrog DNA, vim qhov loj ntawm biomolecules (DNA feem ntau yog ntau txhiab kDa). Rau cov protein gels, polyacrylamide muab daws teeb meem zoo, raws li qhov me me me (50 kDa yog qhov raug) zoo dua rau qhov sib txawv ntawm cov gel.
Thaum twg siv cov khoom siv?
Throughput yog hais txog ntau npaum li cas cov ntaub ntawv tuaj yeem xa los ntawm ib qhov chaw mus rau lwm qhov hauv lub sijhawm. Nws yog siv los ntsuas qhov kev ua tau zoo ntawm hard drives thiab RAM , nrog rau kev sib txuas hauv Is Taws Nem thiab network.
