Thaum kev hloov pauv, yog tias cov tshuaj tiv thaiv tsis sib haum tau qhia, cov tshuaj tiv thaiv tuaj yeem khi rau txawv teb chaws antigens, ua rau lawv sib sau ua ke, lossis: agglutinate.
Yuav ua li cas thaum ib tus neeg tau txais kev hloov pauv nrog cov lus nug ntshav tsis sib xws?
Xaiv tiv thaiv kab mobuas tshwm sim thaum tus neeg tau txais cov ntshav tsis sib xws. Cov qe ntshav liab sib sau ua ke txiav cov ntshav ntws los ntawm cov hlab ntsha thiab cov hlab ntsha.
Yuav ua li cas thaum ob lub qe ntshav tsis sib xyaw ua ke?
Yog ob hom ntshav tsis sib xyaw sib xyaw, nws yuav ua rau agglutination qhov twg cov antigens sib txawv yuav los ua ke thiab ua rau cov ntshav txhaws.
Yuav ua li cas lawv koom nrog hauv lub cev cov lus teb rau cov ntshav tsis sib xws?
Nws muaj ob lub ntsiab ntawm kev tiv thaiv kab mob: humoral (siv cov tshuaj tiv thaiv) thiab cellular (siv lub cev tiv thaiv kab mob) Cov tshuaj tiv thaiv kab mob sib kis mob hnyav feem ntau cuam tshuam nrog caj npab humoral. Nyob rau hauv cov ntaub ntawv ntawm ib tug txawv teb chaws cov ntshav liab antigen, tus neeg mob lub pre-existing antibodies khi rau cov antigen, txheej tus pub RBCs.
Yuav ua li cas thaum muaj cov tshuaj tiv thaiv ntawm cov ntshav liab thiab cov tshuaj tiv thaiv kab mob hauv plasma tsim ib qho nyuaj?
Cov tshuaj tiv thaiv ntawm cov qe ntshav liab thiab cov tshuaj tiv thaiv kab mob sib xws feem ntau tshwm sim hauv clumping- agglutination-ntawm cov hlwb liab; Yog li ntawd, antigens ntawm qhov chaw ntawm cov hlwb liab no feem ntau hu ua agglutinogens.

Los ntawm cov dej hloov pauv cov tshuaj tiv thaiv?
Cov dej-gas hloov pauv cov tshuaj tiv thaiv (WGSR) piav qhia txog tawm tsam carbon monoxide thiab dej vapor los ua carbon dioxide thiab hydrogen : CO + H 2 O ⇌ CO 2 + H. … Ua ntej lub xyoo pua 20th, hydrogen tau txais los ntawm kev ua pa hauv siab nrog hlau los tsim cov hlau, hlau oxide thiab hydrogen.
Puas yog cov tshuaj tiv thaiv kab mob sib txuas tau suav tias yog kev tiv thaiv kab mob?
Antibody drug conjugates (ADCs) yog ib hom tshuaj tiv thaiv kab mob. Lawv yog tsim los ntawm peb yam: monoclonal antibody (mAb) thiab cytotoxic payload ua los ntawm cov kws khomob kws khomob, uas txuas nrog ua ke siv cov tshuaj sib txuas . Puas yog tshuaj tiv thaiv kab mob tib yam li kev tiv thaiv kab mob?
Cov neeg mob tiv thaiv kab mob yuav tsum tau txais cov tshuaj tiv thaiv?
Vim li cas CDC thiaj pom zoo tias cov neeg uas muaj kev tiv thaiv kab mob tiv thaiv kab mob tau txais koob tshuaj mRNA COVID-19 ntxiv los ntxiv rau 2-dose thawj koob tshuaj tiv thaiv kab mob mRNA COVID-19? Cov neeg uas muaj kev tiv thaiv kab mob los yog cov neeg siv tshuaj tiv thaiv kab mob yog nyob ntawm muaj kev pheej hmoo ntau rau tus kab mob COVID-19 hnyav .
