Anatomical terminology. Tight junctions, tseem hu ua occluding junctions los yog zonulae occludentes (singular, zonula occludens) yog multiprotein junctional complexes uas nws canonical muaj nuj nqi yog los tiv thaiv to ntawm solutes thiab dej thiab seals txoj kev paracellular.
Puas muaj kev sib tshuam nruj hauv GI ib puag ncig?
Cov kev sib tshuam nruj, lossis zonula occludens, cov ntaub ntawv ib qho kev cuam tshuam ntawm cov cell epithelial nyob rau hauv lub plab hnyuv thiab daim siabthiab, los ntawm kev txwv kev txav ntawm dej thiab solutes los ntawm qhov chaw intercellular., tuav lub physicochemical cais ntawm cov ntaub so ntswg compartments.
hom cell twg muaj kev sib tshuam nruj?
Cov kev sib tshuam nruj ntawm cov hlwb epithelial xav tias muaj ob lub luag haujlwm no. Ua ntej, lawv ua haujlwm raws li kev txwv tsis pub muaj kev sib kis ntawm qee cov membrane proteins (thiab lipids) ntawm apical thiab basolateral domains ntawm plasma membrane (saib daim duab 19-2).
Dab tsi yog qhov sib txuas sib txuas sib txuas?
Tight junctions form kev nruam intercellular barrier ntawm epithelial cells, uas yuav tsum tau cais cov ntaub so ntswg thiab tswj kev xaiv txav ntawm solutes hla lub epithelium.
piv txwv ntawm kev sib tshuam nruj yog dab tsi?
Tight epithelia muaj qhov sib txuas nruj uas tiv thaiv feem ntau ntawm cov hlwb. Piv txwv ntawm nruj epithelia muaj xws li lub distal convoluted tubule, cov ducts ntawm nephron nyob rau hauv lub raum, thiab cov kua tsib ducts ramifying los ntawm daim siab daim siab.

Roaming aggressiveness yog hais txog lub sijhawm luv luv thiab cov xwm txheej uas yuav ua rau daim npav wireless network nrhiav thiab txuas rau lwm qhov AP. Txhim kho koj qhov kev ua phem roaming nce tus nqi uas koj daim npav network yuav nrhiav AP nrog lub teeb liab muaj zog Kuv yuav tsum teeb tsa kev ua phem rau dab tsi?
Yuav ua li cas yog nruj nruj sab laug loosey?
Thaum koj hnov ib tug neeg hais sab laug, txoj cai nruj nws yog ib txoj hauv kev rau tus ntawd tus neeg yuav tsum nco ntsoov tias cov xov ntawm tus ntsia hlau, txiv ntseej, los yog ntsia liaj qhov rooj los yog koj tig mus rau sab xis kom nruj lawv thiab koj tig mus rau sab laug kom xoob lawv .
Tus neeg muaj koob npe twg yog nruj nruj xyoo 2020?

Puas yog kev nruj nruj ib txwm tshwm sim?
Nyob hauv tib neeg, nruj mortis tuaj yeem tshwm sim sai li plaub teev tom qab tuag. Tsis zoo li cov lus dab neeg thiab kev ntseeg ib txwm muaj, mortis mortis tsis ruaj khov thiab pib dhau li ntawm cov sij hawm pib . Yuav ua li cas mortis ncua sijhawm?
Nyob rau hauv ib qho kev tsis sib haum xeeb pn kev sib tshuam cov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
Nyob rau hauv qhov tsis ncaj ncees PN-kho qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog zero, vim tias sib npaug tab sis cov neeg nqa khoom hla hla kev sib tshuam . Thaum pn kev sib tshuam tsis ncaj ncees qhov kev sib tshuam tam sim no ntawm qhov sib npaug yog?
