Mavairasi (mavairasi a m'chilengedwe) ndi zamoyo zopanda maselo zomwe zimadziwika ndi kukula kochepa, kapangidwe kosavuta, komanso kukhalapo kwa mtundu umodzi wokha wa nucleic acid (DNA kapena RNA). Ayenera kupha maselo amoyo kuti abereke ndikuchulukana. Akalekanitsidwa ndi maselo omwe amawalandira, mavairasi amakhala zinthu zamakemikolo zopanda ntchito iliyonse ya moyo ndipo sangathe kudzipanga okha. Mphamvu zawo zobwerezabwereza, kulemba, ndi kumasulira zonse zimachitika mkati mwa selo lolandira. Chifukwa chake, mavairasi amapanga gulu lapadera la zamoyo lomwe lili ndi mphamvu zamakemikolo ndi makhalidwe ofunikira a zamoyo; amapezeka ngati tinthu tating'onoting'ono tomwe timapezeka kunja kwa maselo komanso majini obwerezabwereza mkati mwa maselo.
Mavairasi paokha ndi ang'onoang'ono kwambiri, ndipo ambiri amatha kupezeka pogwiritsa ntchito maikulosikopu ya elekitironi. Mavairasi akuluakulu kwambiri, poxvirus, amafika pafupifupi 300 nanometers, pomwe ang'onoang'ono kwambiri, circoviruses, ali pafupifupi 17 nanometers kukula. Anthu ambiri amadziwa kuti mavairasi ambiri amawopseza kwambiri thanzi la anthu ndi moyo wawo, monga kachilombo ka corona, kachilombo ka hepatitis B (HBV), ndi kachilombo ka HIV. Komabe, mavairasi ena achilengedwe amaperekanso zabwino kwa anthu. Mwachitsanzo, mabakiteriya amatha kugwiritsidwa ntchito pochiza matenda enaake a mabakiteriya, makamaka akamakumana ndi mabakiteriya akuluakulu omwe maantibayotiki ambiri asiya kugwira ntchito.
M'kuphethira kwa diso, padutsa zaka zitatu kuchokera pamene mliri wa COVID-19 unayamba. Komabe, kuyezetsa nucleic acid kumapitirira patali kuposa kuzindikira kachilombo ka corona. Kupatula COVID-19, kuyezetsa nucleic acid kumakhala ngati muyezo wabwino kwambiri wopezera matenda ambiri mwachangu komanso molondola, kuteteza thanzi lathu nthawi zonse. Tisanayambe kuyezetsa nucleic acid, kupeza ma viral nucleic acid abwino kwambiri ndikofunikira kuti tiwonetsetse kuti njira zodziwira matenda zikuyenda bwino.
Chiyambi cha Zamalonda
Chidule cha Zamalonda:
Kiti iyi ili ndi mikanda ya superparamagnetic ndi ma buffer ochotsera omwe adapangidwa kale, zomwe zimapangitsa kuti zikhale zosavuta, kukonza mwachangu, kukolola kwakukulu, komanso kuberekana bwino kwambiri. DNA/RNA ya ma gene omwe amabwera chifukwa cha kachilomboka alibe mapuloteni, nuclease, kapena kusokoneza kwina kulikonse, koyenera kugwiritsa ntchito PCR/qPCR, NGS, ndi ntchito zina za biology. Mukaphatikizana ndiNsomba YaikuluChotsukira cha nucleic acid chopangidwa ndi maginito chokhala ndi bead, ndi choyenera kwambiri pochotsa zitsanzo zambiri zokha.
Zinthu Zogulitsa:
Kugwiritsa Ntchito Zitsanzo Zambiri: Koyenera kuchotsa nucleic acid kuchokera ku magwero osiyanasiyana a mavairasi a DNA/RNA, kuphatikizapo HCV, HBV, HIV, HPV, ndi mavairasi oyambitsa matenda a nyama.
Mwachangu komanso Mwachangu: Ntchito yosavuta yomwe imafuna kuwonjezera zitsanzo zokha musanayambe kukonza makina, kuchotsa kufunikira kwa njira zingapo zoyezera. Imagwirizana ndi zochotsera za nucleic acid zapadera, makamaka zoyenera kukonza zitsanzo zapamwamba.
Kulondola Kwambiri: Dongosolo lapadera la buffer limatsimikizira kuti limatha kuberekanso bwino kwambiri pochotsa zitsanzo za mavairasi zomwe sizili ndi kuchuluka kokwanira.
