Pluripotent hlwb tuaj yeem ua rau tag nrho ntawm ntawm tes hom uas ua rau lub cev; embryo qia hlwb raug txiav txim siab pluripotent . Ntau tus neeg muaj zog hlwb tuaj yeem loj hlob mus rau ntau tshaj ib ntawm tes hom, tab sis muaj ntau txwv ntau dua pluripotent cell ; neeg laus qia hlwb thiab cov hlab ntsha qia hlwb suav hais tias yog multipotent.
Ntxiv mus, qhov txawv ntawm pluripotent thiab totipotent qia hlwb yog dab tsi?
Lub peev xwm no los ua txhua yam ntawm cell hauv cev hu pluripotent . Cov qhov sib txawv ntawm totipotent thiab pluripotent cell tsuas yog qhov ntawd totipotent hlwb tuaj yeem ua rau cov placenta thiab lub embryo. Raws li lub embryo loj hlob cov no pluripotent cell txhim kho mus rau tshwj xeeb, multipotent qia hlwb.
Tsis tas li, dab tsi ntxias pluripotent qia hlwb? Induced Pluripotent Stem Cells (iPS) iPSC yog muab los ntawm daim tawv nqaij lossis ntshav hlwb uas tau reprogrammed rov qab mus rau hauv lub embryonic-zoo li pluripotent xeev uas tso cai rau txoj kev loj hlob ntawm qhov tsis muaj kev txwv ntawm txhua hom tib neeg lub xov tooj xav tau rau kev kho mob.
Ib yam li ntawd, qhov twg pluripotent qia hlwb pom?
Pluripotent qia hlwb . Pluripotent qia hlwb yog hlwb uas muaj peev xwm rov tsim kho tus kheej los ntawm kev faib thiab tsim mus rau hauv peb lub hauv paus loj ntawm tes txheej ntawm lub embryo thaum ntxov thiab yog li ntawd mus rau tag nrho hlwb ntawm cov neeg laus lub cev, tab sis tsis ntxiv-embryonic cov ntaub so ntswg xws li cov placenta.
Yuav ua li cas kom tau pluripotent qia hlwb?
Pluripotent qia hlwb tuaj yeem tau txais los ntawm inducing dedifferentiation ntawm cov neeg laus somatic hlwb los ntawm kev tsim kho tshiab hauv vitro technology, hu ua cell reprogramming [6, 7].

Puas yog tag nrho cov kuab tshuaj yaj hauv cov kuab tshuaj?
Cov kuab tshuaj thiab cov kuab tshuaj tuaj yeem yog txhua yam teeb meem. Muaj ntau cov kuab tshuaj yaj nyob rau hauv dej vim dej yog ib tug heev polar compound. Ib txoj cai dav dav: zoo li dissolves nyiam. Piv txwv li, cov kuab tshuaj polar yaj cov tshuaj solar polar, thiab cov kuab tshuaj nonpolar yaj cov nonpolar solutes
Puas yog tag nrho cov hlab ntsha nqa cov ntshav oxygenated thiab cov leeg nqa cov ntshav deoxygenated?
Cov hlab ntsha ua ib feem ntawm lub circulatory system. Cov hlab ntsha nqa cov ntshav oxygenated tawm ntawm lub plawv mus rau cov ntaub so ntswg, tshwj tsis yog cov hlab ntshav hauv lub ntsws, uas nqa ntshav mus rau lub ntsws rau cov pa oxygen (feem ntau cov leeg ntshav nqa cov ntshav deoxygenated mus rau lub plawv tab sis cov leeg hauv ntsws nqa cov ntshav oxygenated ib yam)
Puas yog tag nrho cov pob qij txha muaj cov kua dej synovial?
Tag nrho cov pob qij txha synovial muaj cov kab mob sib koom ua ke uas muaj cov kua dej synovial uas yog qhov chaw uas cov pob txha ntawm cov pob qij txha sib koom ua ke. Cov tawv nqaij ua haujlwm ntawm cov pob txha tau npog los ntawm cov pob txha pob txha, ib txheej nyias ntawm pob txha mos hyaline
Puas yog tshuaj dawb tua tag nrho cov kab mob thiab cov kab mob?
Bleach yog ib qho tshuaj tua kab mob uas pheej yig thiab muaj txiaj ntsig zoo. Nws tua qee cov kab mob txaus ntshai tshaj plaws, suav nrog staphylococcus, streptococcus, E. coli thiab salmonella - nrog rau ntau yam kab mob, suav nrog mob khaub thuas thiab mob khaub thuas
Cov thyroid cancer puas tuaj yeem rov ua dua tom qab tag nrho cov thyroidectomy?
Cov qog nqaij hlav qog nqaij hlav rov tshwm sim tuaj yeem tshwm sim xyoo-txawm xyoo caum-tom qab pib kho tus kab mob. Hmoov zoo, txawm li cas los xij, kev mob qog nqaij hlav thyroid rov qab tuaj yeem kho tau. Mob qog noj ntshav tau kho, ib feem, los ntawm kev phais tshem tawm tag nrho lossis ib feem ntawm cov qog qog, cov txheej txheem hu ua thyroidectomy
