Abantu abaphezulu bemvelo abaphezulu kwisayensi:

I-yunlong cao ye-Peking eyunivesithi ebizwa ngegama elisha locwaningo olusha lweCoronavirus

Ngomhlaka 15 kuZibandlela 2022, imvelo yamemezela ubunjalo bawo be-10, kuluhlu lwabantu abayishumi abebeyingxenye yemicimbi emikhulu yesayensi, futhi izindaba zabo zinikeza umbono oyingqayizivele kwezinye zezehlakalo ezibaluleke kakhulu zesayensi zalo nyaka.

Ngonyaka wezinkinga nokutholwa okuthokozisayo, imvelo yakhetha abantu abayishumi abavela kwizikhathi zezinkanyezi esibasizile ukuba babuhlakani obude kakhulu bomhlaba, kubacwaningi abasebenza ngocingo olubi kakhulu emqheleni omusha kanye nabakwaMoneypox ababambe umkhawulo wokufakelwa kwezitho, kusho uCich Monastersky, umhleli-in-induna yezici zemvelo.

I-Yunjong Cao ivela enkabeni ye-biomedical Frontier Innovation Center (Biopic) ePeking University. UDkt CAO uthweswe iziqu e-zhejiang University nge-bachelor degree e-physics futhi wathola i-PhD yakhe eHarvard University eHarvard University ngaphansi kwe-Xiaoliang Xie, futhi njengamanje uyi-Associate e-Biomedical Frontier Innovation Center ePeking University ePeking University ePeking University. UYunjong Cao ubelokhu egxile ekuthuthukisweni kobuchwepheshe obuhleliwe obuhlelekile, futhi ucwaningo lwakhe lusize ukulandelela ukuvela kwama-coronaviruses amasha futhi ngabikezela ezinye zezinguquko eziholela ekwakhiweni kwama-multant amasha.

Ngo-18 Meyi 2020, iXiaoliang Xie / Yunlong cao et al. Ishicilelwe iphepha ekhasini le-payli elinesihloko esithi: "Amasosha ama-antibodies anamandla abhekene ne-SARS-Cov-2 ekhonjwe ngokulandelana okuphezulu kweseli elilodwa lamaseli e-convalescent iziguli ze-BAST" B iphepha lokucwaninga.

Lolu cwaningo lubika imiphumela ye-coronavirus entsha (SARS-Cov-2) Ukunciphisa i-antibody screen eyodwa, esebenzisa indawo yokulandelana okuphezulu kwe-RNA ne-VDJ yokulandelana ukuthola ama-antibodies angaphezu kuka-85 ubudala e-IGG1 ezivela kuma-antibodies angama-60 atholakele e-Covid-19 iziguli.

Lolu cwaningo lukhombisa okokuqala lapho ukulandelwa kweseli elilodwa lokungena ngaphakathi kungasetshenziselwa ukutholakala kwezidakamizwa futhi kube nenzuzo yokuba yinqubo esheshayo nephumelelayo, ethembisa ukuguqula indlela abantu ama-antibodies angenakuthethelela amagciwane.

Ngomhlaka 17 Juni 2022, xiaoliang Xie / Yunlong cao et al. Ishicilelwe Iphepha Elinesihloko esithi: BA.2.12.1, i-BA.4 ne-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 I-BA.5 ENCOLO

Lolu cwaningo luthole ukuthi ama-subtype amasha e-omicron mutant perkins ba.2.12.1, bheka uBa.4 noBa.5 bakhombisa ukukhuphuka komzimba nokungathathi hlangothi kwe-plasma kuphunyuke e-Omicron Ba.1 Iziguli ezinegciwane.

Lokhu okutholakele kusikisela ukuthi umuthi wokugomela i-BA.1 osuselwa ku-Omicron kungenzeka ungasafaneleki njenge-booster kumongo wokugoma wamanje nokuthi ama-antibodies adonswayo ngeke anikeze ukuvikelwa okubanzi kwe-mutant kubunzima obusha. Ngaphezu kwalokho, ukungatheleleki komhlambi ngo-Omicron kunzima kakhulu ukufeza ngenxa yento 'ye-immunogenic' yento entsha yama-coronaviruses kanye nokuvela okusheshayo kwezindawo zokuguqulwa komzimba.

Ngomhla zingama-30 ku-Okthoba 2022, iqembu likaXiaoliang Xie / Yunlong CAO lishicilele iphepha elithi Ucwaningo Olunesihloko esithi: I-SARS-Cov-2 Hurmitive Influsity iduduza i-Omicron RBD Evolution ku-biolxiv ye-Preprint biolxiv.

Lolu cwaningo lubonisa ukuthi inzuzo ye-XBB ngaphezulu kwe-BQ.1 ingahle ibekwe ngokwengxenye yangemuva kwesizinda se-spinosin (i-XBB futhi ikwazi ukuphunyula izingxenye ze-spinosin, i-XBB futhi ikwazi ukuthelela abantu ama-antibodinal nge-BQ.1 futhi ehlobene nayo ama-subtypes. Kodwa-ke, kufanelekile ukuthi ukubheka ukuthi izinguquko ezifundweni ze-NTD zenzeka ku-BQ.1 ngesilinganiso esisheshayo. Lezi zinguquko zithuthukisa kakhulu ikhono lalezi zinhlobonhlobo zokubalekela ama-antibodies angathathi hlangothi akhiqizwa ngokugoma nokutheleleka kwangaphambili.

UDkt Yundong Cao uthe kungenzeka kube nokuvikelwa ku-XBB uma etheleleke nge-BQ.1, kodwa kudingeka ucwaningo olwengeziwe ukuze kunikezwe ubufakazi ngalokhu.

Ngaphezu kwe-yunjong cao, abanye abantu ababili benze lolu hlu ngeminikelo yabo evelele ezindabeni zezempilo zomphakathi zomphakathi, uLisa McCorkell noDieie Ogoina.

ULisa McCorkell ungumcwaningi onekhono ende nanjengeLungu Lokusungula Ucwaningo Oluhlanganyelwe, usize ekuqwashiseni nasezimalini ukuze zicwaninge ngalesi sifo.

UDimie Ogoina ungudokotela wezifo ezithathelwanayo eyunivesithi eNiger Delta eNigeria nasekusebenzeni kwakhe kuMokeypox Ubhubhane eNigeria unikeze imininingwane ebalulekile ekulweni ne-monkeypox ubhubhane.

Ngomhlaka 10 kuJanuwari 2022, i-University of Maryland School of Medical Medicated Inhliziyo yokuqala ehlelwe ngohlobo lwezinhlobo zenhliziyo enezingane eziphilayo ezweni eliphilayo, lapho isiguli esineminyaka engu-57 ubudala uDavide uDavid Bennett ethola impilo yakhe.

Yize le nhliziyo yengulube idlulisela kuphela impilo kaDavid Bennett ezinyangeni ezimbili, kube yimpumelelo enkulu kanye ne-accough angokomlando emkhakheni we-xenotransplant. UMuhammad Mohiuddin, udokotela ohlinzayo owahola iqembu eliphothule lokhu kufakelwa komuntu kwenhliziyo yengulube ehlelwe ngofuzo, ngokungangabazeki kwakubizwa ngegama labantu abayi-10 endalo yohlu lonyaka.

Abanye abaningana bakhethwa ukuthuthukisa impumelelo yesayensi evamile nentuthuko ebalulekile yenqubomgomo, kufaka phakathi i-astronomer iJane Rightby of NASA's Goddard Space Center ukuthola isibonakude futhi asebenze kahle, ukuthatha ikhono lesintu lokuhlola indawo yonke. I-Alondra Nelson, njengoMqondisi Wezinqubomgomo ze-US Science and Technology wasiza ukuphathwa kwebhideneli kaMongameli ukuba athuthukise izinto ezibalulekile ze-ajenda yayo yesayensi, kubandakanya nenqubomgomo ngobuqotho besayensi kanye nemihlahlandlela emisha kwisayensi evulekile. I-Diana Greene Foster, umcwaningisi isisu isisu e-University of California, eSan Francisco, ihlinzeke ngemininingwane ebalulekile kumthelela olindelekile wesinqumo seNkantolo ephakeme yase-US ukuqeda izivikelo ezingokomthetho zamalungelo okuhushula isisu.

Kukhona namagama ohlwini oluyishumi ophambili lwalo nyaka olufanele ekuthuthukisweni kokushintsha kwesimo sezulu nezinye izingxabano zomhlaba wonke. Yilezi: Unobhala-Jikelele we-António, Jikelele we-United Nations, Umqondisi Wezizwe Zamazwe Amazwe Amazwe Amazwe Okuguquguquka kwe-Dhaka, e-Induction of Ukraine ephanelisweni yesimo sezulu ekushintsheni kwesimo sezulu (IPCC).
