Phaj kho los yog kab mob kev kho mob yog kho mob siv cov kab mob bacteriophages los kho cov kab mob pathogenic. Phaj txuas rau cov kab mob ntawm cov kab mob, thiab txhaj cov kab mob kis rau hauv lub cell. Cov kab mob kis tau zoo hloov pauv cov kab mob genome, txwv tsis pub kis kab mob.
Tsuas yog li ntawd, phage ua haujlwm li cas?
Hauv lub voj voog lytic, a phage ua zoo li tus kab mob ib txwm muaj: nws hijacks nws tus tswv tsev thiab siv cov cell cov peev txheej los ua ntau yam tshiab phages , ua rau lub cell lyse (burst) thiab tuag nyob rau hauv cov txheej txheem. Nkag: phage txhaj nws ob txoj hlua DNA genome rau hauv cytoplasm ntawm cov kab mob.
Tsis tas li ntawd, kev kho phage siv sijhawm ntev npaum li cas? Xaiv tshiab phages (e.g., tiv phage -cov kab mob uas tsis muaj zog) yog tus txheej txheem nrawm uas tuaj yeem ua tiav ntau hnub lossis ntau lub lis piam. Kev tsim cov tshuaj tua kab mob tshiab (piv txwv li, tiv thaiv cov kab mob tiv taus tshuaj tua kab mob) yog txheej txheem siv sijhawm thiab yuav coj ntau xyoo (16, 51).
Ntawm no, ua li cas phages tua cov kab mob?
Bacteriophages tua cov kab mob los ntawm kev ua rau lawv tawg los yog lyse. Qhov no tshwm sim thaum tus kab mob txuas rau kab mob . Tus kab mob kis tau rau kab mob los ntawm txhaj nws cov noob (DNA lossis RNA). Cov phage tus kab mob luam nws tus kheej (rov tsim dua) hauv kab mob.
Puas yog phages zoo?
Bacteriophage txhais tau tias "noj cov kab mob," thiab cov kab mob zoo li kab laug sab no tuaj yeem yog qhov muaj sia nyob tshaj plaws hauv ntiaj teb. HIV, Kab mob siab C, thiab Ebola tau muab cov kab mob rau lub npe tsis zoo, tab sis me me phages yog cov zoo cov txiv neej ntawm virology ntiaj teb. Phaj kev kho mob muaj ntau yam zoo dua cov tshuaj tua kab mob.

Tib neeg, tsev kawm ntawv thaum ntxov ntawm kev xav uas hais txog tias txhua tus tib neeg yog tus neeg zoo thiab mob siab rau kawm thiab txhim kho kom dhau los ua neeg noj qab haus huv, ua haujlwm tau zoo
Puas yog kev daws teeb meem kev kho mob tib yam li kev daws teeb meem luv luv kho?
Kev kho mob tsom mus rau kev kho mob, tseem hu ua kev daws teeb meem hais qhia luv (SFBT), yog hom kev kho mob uas muab qhov tseem ceeb tshaj ntawm kev tham txog kev daws teeb meem ntau dua (Berg, nd) Lo lus "luv luv" hauv kev kho mob luv luv yog qhov tseem ceeb
Thaum tus kws kho mob tau tso cai tso cai ntau npaum li cas yuav tsum muaj kev sib ntsib tim ntsej tim muag tshwm sim ntawm tus kws kho mob thiab cov kws kho mob qib siab uas tau sau npe rau tus nais maum?
Txawm li cas los xij, yog tias APRN lossis PA tau nyob hauv daim ntawv pom zoo tso cai nrog kws saib xyuas kws kho mob tsawg kawg tsib ntawm xya xyoo dhau los, cov rooj sib tham tim ntsej tim muag yuav tsum tshwm sim tsawg kawg ib hlis txog rau thawj hnub ntawm hnub uas tau pom zoo kos npe
Lub xovtooj ntawm kev sib kho nruab nrab thiab kev txo hwjchim ua haujlwm li cas?
Humoral kev tiv thaiv zais cov tshuaj tiv thaiv los tawm tsam antigens, qhov kev tiv thaiv cell-mediated tiv thaiv zais cytokines thiab tsis muaj cov tshuaj tiv thaiv los tua cov kab mob. Kev tiv thaiv Humoral yog nrawm lossis nrawm hauv lawv qhov kev tawm tsam tiv thaiv antigens, thaum Cell-mediated immunity qhia qeeb txawm tias ua haujlwm mus tas li tawm tsam cov kab mob
Txoj kev kho tus cwj pwm twg yog siv los kho kev ntxhov siab lossis kev ntshai?
Kev kho tus cwj pwm kev paub (CBT) yog kev siv dav tshaj plaws rau kev ntxhov siab. Kev tshawb fawb tau qhia tias nws muaj txiaj ntsig zoo hauv kev kho mob ntawm kev ntxhov siab, phobias, kev ntxhov siab hauv zej zog, thiab kev ntxhov siab ntau yam, ntawm ntau lwm yam mob
