LONDON: Scientists at the University of Cambridge working with an anti-viral coating technology called DioX believe that it could protect face mask users by killing the deadly coronavirus in as little as an hour.

According to ‘The Daily Telegraph’, the invisible coating on facemasks attacks the virus by rapturing its outer layer, effectively eliminating all new mutant variants, including the UK’s so-called Kent variant and the South African variant.

“The antiviral agent within the coating of the mask kills the virus by breaching its protective outer membrane, which is known as its envelope. Unlike other parts of the virus, the membrane remains the same regardless of any type of mutation. Hence this way of attacking the pathogen will work on any new variant of coronavirus,” Dr Graham Christie, senior lecturer at the Department of Chemical Engineering and Biotechnology at the University of Cambridge, told the newspaper.

“In fact, you could mutate the entire genome of the virus and it would have no effect on the envelope. We expect to see the same response regardless of the strain of coronavirus because structurally they are all very similar,” he said.

The technology called DiOX is based on quaternary ammonium salts – organic compounds widely used in the textile industry for their antimicrobial properties. Laboratory tests showed that the mask coated with it killed 95 per cent of pathogens on its surface within one hour and they were undetectable after four hours.

Experts say the action of the antiviral agent continues to work because it is unaffected by changes in the spike protein of the virus, which is the method by which coronavirus mutates.

“The variants that we are seeing occur in the spike proteins that stud the surface of the virus rather than the membrane of the envelope,” said Dr Christie.

“It is the genetic information that encodes this protein that is mutating, and this is leading to very slight structural changes in the shape of the spike. However, the envelope is derived from part of a human cell that the virus grabs from its host in order to protect its genetic material. It is made from lipids, which unlike the proteins do not change,” he said.

According to the newspaper report, the mask is reusable and can be washed up to 20 times, albeit subject to a reduction in efficacy after multiple washes. During the study, the mask was tested on a coronavirus called MHV-A59, which is genetically and structurally very similar to SARS-CoV-2.

“The Cambridge work followed industry standards for the testing of viruses on material,” said Andy Middleton, co-founder of LiquidNano, the UK company which commissioned the study.

“It also made some critical adaptations to give it a more ‘real-world’ relevance. This included conducting splash tests to mimic sneezing, helping to ensure the tests were as rigorous as possible. We have taken a proven antiviral agent and developed it for fabric in order to create a user-friendly mask,” he said.

DioX D4 claims to offer a patented technology for inhibiting the growth of a wide array of bacteria, mould, mildew, algae, fungi, and yeast on textile materials.

The novel antimicrobial agent provides an invisible microbiostatic coating to inhibit the growth of odour causing bacteria. Given the coronavirus pandemic, DiOX D4 said it has also been independently tested to rapidly reduce bacterial and viral pathogens, “greatly limiting the risk of contact contamination and infection”.

If proved effective in further analyses, the technology could offer an additional layer of protection against deadly viruses over time.

15 juta penduduk UK terima suntikan pertama vaksin

February 16, 2021 | News | No Comments

Lebih 15 juta penduduk United Kingdom (UK) sudah menerima suntikan dos pertama vaksin Covid-19.

Perdana Menterinya, Boris Johnson memuji prestasi luar biasa itu yang dicapai lebih dua bulan selepas individu pertama di negara itu menerima suntikan vaksin itu pada 8 Disember lalu.

BBC melaporkan kerajaan dijangka secara rasmi mengumumkan kejayaan itu pada Isnin.

Ia sekali gus memenuhi janji untuk menawarkan suntikan kepada empat kumpulan paling utama di negara itu.

Empat kumpulan terbabit adalah penghuni rumah penjagaan orang tua dan kakitangannya; individu berusia 80 tahun ke atas, petugas barisan hadapan dan penjaga; individu berusia 75 tahun dan ke atas; dan mereka yang paling mempunyai risiko masalah kesihatan.

Suntikan vaksin selepas ini akan diperluas membabitkan individu berusia lebih 65 tahun dan mereka yang lemah secara klinikal.

Dalam satu video, Johnson memuji usaha berkenaan dengan menyatakan bahawa suntikan vaksin di England sudah ditawarkan kepada semua individu di dalam empat kumpulan utama berkenaan.

Wales juga sudah merekodkan kejayaan sama.

“Kami masih punya jalan panjang. Dan pasti akan ada banyak jalan.

“Tetapi selepas semua yang kami capai, saya tahu kita dengan yakin merekodkan kemajuan,” kata Johnson.

Statistik pada Ahad menunjukkan 15,062,189 orang sudah menerima dos pertama vaksin itu di UK.

Ia selepas 505,362 individu menerima suntikan pertama vaksin itu, sehari sebelumnya.

Dalam pada itu, statistik menunjukkan 258 orang lagi meninggal dunia di UK, dalam tempoh 28 hari selepas disahkan positif Covid-19.

Ia menjadikan jumlah keseluruhan kematian akibat virus itu di UK kepada 117,166 orang.

Setakat ini, negara itu merekodkan 4,038,078 positif Covid-19.

MOSCOW – Satu lagi varian Covid-19 (B.1.525) dikesan di United Kingdom (UK), serta 10 negara lain, termasuk Amerika Syarikat (AS) lapor Agensi Berita Sputnik.

Menurut penyelidik University of Edinburgh dalam satu laporan pada Isnin, strain baharu telah ditemui melalui pengesanan genom di 11 negara: UK, Nigeria, Denmark, AS, Perancis, Belgium, Sepanyol, Kanada, Australia, Ghana, dan Jordan.

Denmark mencatatkan jumlah kes tertinggi B.1.525 sebanyak 35 kes, diikuti UK 33 kes, Nigeria 12 kes dan AS 10 kes manakala Perancis setakat ini melaporkan lima kes.

Rantaian terawal strain baharu Covid-19 itu dikesan pada Disember 2020 dengan kes pertama muncul di UK dan Nigeria.

Varian baharu itu dilihat menyamai jenis Afrika Selatan dan Brazil dan lebih berdaya tahan terhadap antibodi.

Varian baharu Covid-19 cetus kebimbangan

December 22, 2020 | News | No Comments

Laporan penyelidik dari United Kingdom (UK) dan Afrika Selatan berhubung varian baharu Covid-19 yang didakwa lebih mudah merebak telah mencetuskan kebimbangan ramai walaupun pakar virus percaya ia tidak akan melemahkan imuniti vaksin.

Selain itu, pakar kesihatan di UK dan Amerika Syarikat (AS) juga memaklumkan virus yang telah mengalami mutasi itu lebih mudah menjangkiti orang lain.

Ketika ini, tiada bukti menunjukkan ia lebih berbahaya berbanding virus asal, namun kebanyakan negara telah mengambil langkah berjaga-jaga mengumumkan larangan penerbangan dan perjalanan dari UK.

Ketua Penasihat Saintifik di London, Patrick Vallance berkata, virus tersebut merebak dengan cepat dan berada ‘di luar kawalan’ serta menjadi varian dominan yang menyebabkan lebih 60 peratus jangkitan di ibu negara UK pada bulan ini.

Kebimbangan paling besar adalah apabila virus bermutasi dengan mengubah protein pada permukaannya, sekali gus menjadikan ia ‘kebal’ daripada ubat-ubatan atau sistem imun.

“Bukti yang muncul percaya keadaan itu mungkin berlaku dengan koronavirus baharu tersebut. Kini, kita menyaksikan penyebaran beberapa varian dan sebahagian daripadanya menunjukkan ketahanan terhadap rawatan antibodi,” kata Pakar Genetik di Pusat Penyelidikan Barah Fred Hutchinson di Seattle, Trevor Bedford.

Sementara itu, Ketua Penasihat Usaha Pengedaran Vaksin di AS, Dr Moncef Slaoui percaya kemungkinan varian baharu itu ‘kebal’ terhadap vaksin adalah rendah. – Agensi

Info:

  • Pada April lalu, penyelidik di Sweden menemui virus yang mengalami dua perubahan genetik yang menjadikan ia kira-kira dua kali ganda lebih berjangkit.
  • Beberapa variasi virus juga dikesan membabitkan individu yang mendapat jangkitan daripada ladang cerpelai di Denmark.
  • Pada Jumaat lalu, Afrika Selatan turut mengenal pasti virus yang mengalami mutasi yang mencetuskan gelombang jangkitan kedua di negara itu.

  • Varian baharu di UK didakwa mempunyai dua perubahan atau lebih termasuk lapan lonjakan protein.

The UK Secretary of State for Foreign Affairs, Dominic Raab recently took to his Twitter page to thank Malaysia for its contribution to frontliners in the UK, as Malaysia sent over 200 tonnes of gloves. One netizen, Greg (@UKRegulator) replied to Raab’s tweet with what seemed like a response that questioned the quality of the gloves.

Dominic Raab wrote, “200 tonnes of gloves for the National Health Service (NHS) arrived in the UK from Kuala Lumpur, heading for our frontline healthcare workers. A huge thank you to our friends in the Malaysian government for facilitating this.”

Greg then replied, “Will they meet UK quality standards? Can you point to Malaysia on a map?”

Triggering Malaysians’ wrath

Malaysians clearly didn’t take well to the comment as he was insulting the quality of the gloves. Many took to Twitter to respond to Greg, including Malaysian actress, singer, activist and philanthropist Maya Karin.

His tweet was actually sarcasm and aimed at someone else

Though, it seems that Greg’s snarky comment was aimed at Malaysia at all, but instead was a sarcastic comment made towards Dominic Raab, as he tried to explain to the Malaysians bombarding him with responses.

I guess it’s safe to say that Malaysia wasn’t exactly his target when he made the comment.

Well, Greg, you honestly have nothing to worry about as Malaysia is home to the world’s largest manufacturer of gloves, Top Glove, that has received global recognition for it’s quality.

Belum masanya UK tarik balik lockdown

May 12, 2020 | News | No Comments

Perdana Menteri United Kingdom (UK), Boris Johnson semalam mengumumkan pelan tiga peringkat untuk melonggarkan lockdown dikuatkuasakan selama hampir tujuh minggu di seluruh negara di tengah-tengah kebimbangan risiko berlakunya gelombang kedua jangkitan koronavirus (Covid-19) di rantau Eropah.

Di bawah langkah itu, sekolah dan operasi premis perniagaan akan mula dibuka bermula 1 Jun depan jika kadar jangkitan berada pada tahap rendah.

Johnson yang pernah didiagnos positif Covid-19 dan dirawat selama seminggu termasuk dimasukkan di unit rawatan rapi (ICU) menyatakan masih terlalu awal untuk melonggarkan sekatan seperti dibuat negara Eropah lain.

“Belum masanya untuk menarik balik sekatan serta-merta pada minggu ini,” ujarnya yang turut mengumumkan ‘pelan bersyarat’ untuk meredakan sekatan itu dalam tempoh beberapa bulan.

Menurutnya, kerajaan akan menggalakkan orang ramai dalam sektor pembuatan dan pembinaan kembali bekerja bermula minggu ini.

Selain itu, ia juga mengehadkan aktiviti di luar yang akan dibenarkan bermula esok dan hanya melibatkan individu dalam keluarga yang sama.

Di bawah peringkat kedua, taman asuhan kanan-kanak dan sesi persekolahan serta operasi perniagaan tidak penting hanya akan bermula seawal 1 Jun.

Ia disusuli dengan peringkat ketiga pada Julai depan melibatkan pembukaan semula industri perhotelan dan tempat awam yang masih akan melaksanakan langkah penjarakan sosial.

Di Perancis dan Sepanyol, jutaan penduduk kembali menjalani aktiviti seperti biasa hari ini selepas pemerintah masing-masing melonggarkan sekatan susulan penurunan kadar kematian yang didakwa paling rendah sejak awal April lalu.

Ketika ini, terdapat ketidakpastian di Jerman berikutan satu daerah perlu melaksanakan semula lockdown susulan penularan wabak itu di sebuah kilang pemprosesan daging selain kadar jangkitan meningkat kembali.

Selain itu, Belgium dan Greece adalah antara negara Eropah yang turut melonggarkan lockdown.

As we all know, Malaysians who return from overseas are mandated to be quarantined in quarantine centres for 14 days. Most quarantine centres are established hotels such as Hilton and even the Palace of Golden Horses. Unfortunately, despite all this comfort, there have been certain people who still managed to find something to complain about.

Amidst that, Abiramy Komaraswamy, an LLM student from the UK reached out to us to share her experience.

Abiramy shares with WORLD OF BUZZ her story of being quarantined at the Impiana KLCC for the past 14 days. She had nothing but praises towards the hotel staffs and frontliners who took care of them in the quarantine centre.

“Today I’m a proud lady of Malaysia. I would shout out loud and say I love Malaysia.”

“I’m extremely amazed with how Malaysia is handling, managing and protecting everyone in the country during this pandemic.”

Abiramy, whose quarantine ends today told that everything was extremely systematic and properly handled. She added that she has nothing to complain about and that she’s even amazed.

“Meals were always given on time and we had proper health screenings with so many essentials given, without us even requesting,” she said.

She also said that she would like to thank all out hardworking frontliners who’ve been battling this Covid-19 pandemic day and night. In the end, she simply said how proud she is to be Malaysian today and that Home means Malaysia!

We need more Malaysians like Abiramy who truly appreciate the effort by our Malaysian government. Let’s never forget what our frontliners did for us during this pandemic!
