Ib pab neeg tshawb fawb los ntawm University of Liverpool tau tsim cov khoom tshiab uas tuaj yeem ntes cov kab mob coronavirus zoo. Qhov kev tawg no tuaj yeem txhim kho kev ua tau zoo ntawm lub ntsej muag lub ntsej muag thiab cov ntxaij lim dej, ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv kev sib kis ntawm Covid-19 thiab lwm yam kab mob.
Hauv lawv txoj kev tshawb fawb luam tawm hauv Nature Communications, Liverpool cov kws tshawb fawb tau pom tias cov khoom siv tshiab, thaum muab tso rau hauv lub ntsej muag tus qauv, tau nthuav tawm qhov zoo siab 93% nce hauv kev ntes cov protein, suav nrog cov kab mob coronavirus. Zoo kawg li, qhov kev txhim kho no tau cuam tshuam tsawg kawg nkaus rau kev ua pa.
Txoj kev loj hlob ntawm cov khoom no yog coj los ntawm xibfwb Peter Myers, tus kws tshaj lij hauv chromatography, thiab Dr Simon Maher, tus kws tshaj lij hauv huab hwm coj spectrometry. Lawv tau koom tes nrog cov txheej txheem ua kua chromatography siab heev, tsom rau cov proteins uas ua raws li cov ntaub ntawv txhawb nqa chromatographic.
Thaum lub sijhawm muaj kev sib kis, tus xibfwb Myers tau muaj kev pom zoo tias kev thim rov qab cov txheej txheem no tuaj yeem ua rau kev nqus cov protein, tshwj xeeb tshaj yog cov protein S1 spike uas npog cov lipid daim nyias nyias ntawm SARS-CoV-2 tus kab mob.
Pab neeg tshawb fawb los ntawm University of Liverpool Department of Chemistry thiab Hluav Taws Xob Engineering thiab Electronics tau ua haujlwm ua ke los hloov kho qhov chaw ntawm lawv cov chromatography spherical silica particle. Lawv ua kom nws nplaum heev rau Covid-19 S1 spike protein los ntawm "rov kho dua" nws. Tsis tas li ntawd, lawv tau nce qhov particle qhov porosity, ua rau thaj tsam loj ntawm 300m2 ib gram, zoo ib yam li lub tsev hais plaub ntaus pob tesniv. Lub ntim sab hauv ntawm silica sphere kuj tau nthuav dav kom haum rau cov kab mob loj.
Txawm hais tias tseem nyob rau hauv cov ntaub ntawv pov thawj ntawm lub tswv yim theem, cov khoom tshiab twb tau qhia nws cov txiaj ntsig ntawm lub ntsej muag lub ntsej muag thiab ntau lub tshuab lim cua, xws li cov siv dav hlau, tsheb, thiab cov tshuab cua txias.
Cov pab pawg tshawb fawb, uas suav nrog Liverpool Tsev Kawm Ntawv ntawm Tshuaj Kho Mob Kub Kub, kuj tau tsim ib txoj hauv kev los txuas cov nplaum nplaum no rau lub ntsej muag lub ntsej muag.
Xib fwb Peter Myers tau hais ntxiv tias qhov kev tshawb fawb no tsuas yog qhov pib xwb, muaj peev xwm loj dhau ntawm Covid-19 kev hem thawj. Pab neeg no tsom mus tsim cov nplaum nplaum ntau dua uas muaj peev xwm ntes tau ntau yam ntawm bioaerosols, suav nrog BA.2 tshiab.86 Covid variant, kab mob khaub thuas, thiab lwm yam kab mob tuag taus zoo li Nipah.
