25.01.2022 The global march of COVID-19 is beginning to look unstoppablebut its speed and impact can be mitigated. Heres what experts are saying.

12.01.2022 Interesting discovery! So, basically if you have survived the SARS 2003 outbreak, which was caused by SARS-CoV, then you may already have some antibodies that ...can recognize not only the old virus (SARS-CoV), but also the new one (SARS-CoV-2), which is causing COVID-19. This is because both viruses are strikingly similar to each other in many ways. One problem though, the newly discovered antibody reacts strongly to SARS-CoV (the old virus) and weakly to SARS-CoV-2 (the new virus). Although it binds to the new virus, it doesnt neutralize (kill) it. So, researchers hope to do two things: 1- Use it to learn more about the potential vulnerabilities of the new virus thats causing COVID-19. 2- Modify it to react strongly to the new virus, which could then be used as a vaccine.

09.01.2022 An Australian-made coronavirus copy has reached our high-security laboratory in Geelong, where scientists will become the first to test and examine the grown virus to learn more about how it is behaving.

09.01.2022 Detection of SARS-CoV-2 using qRT-PCR ******************************************** 1- Collect specimens (e.g. Nasopharyngeal swab) 2- Preserve specimens in the ...Viral Transport Medium (VTM) 3- Extract the viral RNA using a Viral RNA Mini Kit. 4- Prepare the qRT-PCR Mix (e.g. Superscript III one step RT-PCR). 5- Set the RT-PCR program and launch the reaction: Reverse transcription: 50 C for 15 min (01 cycle) Denaturation: 95 C for 3 min (01 cycle) Amplification: 95 C for 15 s, 58 C for 30 s (40-50 cycles) Cooling: 40 C for 30 s and then 4 C (). qPCR Principle **************** In quantitative PCR we usually use a specific fluorescent probe in addition to primers in order to detect the amplification of the target gene. The probe sequence is labeled at the 5 end with a fluorescent reporter dye (F) and at the 3 end with a quencher dye (Q). In case the probe does not anneal to a specific sequence, the fluorescent reporter will stay physically close to the quencher which will cause the quenching of the reporters fluorescence. However, if the probe anneals to a specific sequence on the target gene, it will be degraded by the 5-3 exonuclease activity of Taq DNA polymerase. The fluorescent reporter will be then released from the quencher which will be no longer close enough to absorb the emission from the reporter dye. The fluorescent signal is thus generated and detected by CCD camera in a LightCycler. The threshold cycle or Ct value is the number of cycles required for the fluorescent signal to cross the fluorescence threshold (the real signal could so be distinguished from background signal). Ct level is inversely proportional to the amount of target RNA in the sample. The lower is the Ct level the bigger is the amount of target RNA in the sample.

05.01.2022 Coronavirus (COVID-19) has officially been declared a pandemic by the World Health Organization (WHO). What does this mean for South Australians? The formal p...andemic declaration doesnt mean you should be alarmed or stockpile. It doesnt mean the virus has become more infectious or more deadly, or that your personal risk of getting the disease is any greater. What it does mean is that we are seeing more cases occurring in more countries. A pandemic can be managed and minimised if we all follow the heath advice we are given and look out for each other. We can all play a part in stopping the spread of infections: Stay home from work and school if you are unwell (e.g. dont go shopping or use public transport until you are well). Avoid contact with others if you are sick (particularly vulnerable people such as older persons and people with chronic medical conditions). If others are sick, keep your distance from them as much as possible (at least 1.5 metres), avoid close contact such as shaking hands, hugging, kissing. Wash hands regularly, particularly after going to the toilet, blowing your nose or handling used tissues. Cover coughs and sneezes with a clean tissue or your elbow. Avoid touching your eyes, nose and mouth, or handling food, until you have washed your hands. Wipe down frequently touched surfaces.

03.01.2022 Great SHE example

03.01.2022 Recent bushfires have affected 272 plant species with 22 of those listed as critically endangered. For 47 plant species, the bushfires have damaged at least 80 ...per cent of their habitat. But many Australian plants have strategies to cope with fire and some species even take advantage of bushfires to germinate. See more
