Biomarkers are components that may be present in biological samples and are related to specific diseases. Therefore, doctors can analyze biological samples from a patient to check their health condition or to monitor the progress of a specific therapy. Typically, these samples need to be purified and diluted before the analysis, and current medical diagnostic … Read more
Tea Covid-19 vaccines authorized for use today were developed at unprecedented speed and surpassed expectations in how well they worked. The billions of people who are protected by them have avoided severe symptoms, hospitalization and deaths. These vaccines are a scientific success beyond measure. And yet they could be even better. The enemy has evolved, … Read more
The ongoing pandemic of coronavirus disease 2019 (COVID-19) has caused severe disruption of social and economic interactions, affecting health services and other important aspects of human life. Until the onset of the Omicron (B.1.1.529) wave, COVID-19 had already had a staggering impact on the world, with over 40% of the world’s population already infected once … Read more
The global outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in the coronavirus disease 2019 (COVID-19) pandemic and has claimed more than 6.26 million lives. Households represent a high-risk exposure setting for SARS-CoV-2 transmission, and the role of children in spreading the virus is not known. A new study published in the … Read more
As Victorians emerged from two years largely defined by lockdowns, the start of 2022 was marked by the sharp rise and fall of cases as a wave of Omicron swept through. That wave, which peaked in early January with tens of thousands of cases per day, subsided somewhat, but epidemiologists warned there would be more … Read more
In a recent study published in Science Advances, researchers generated a recombinant influenza virus expressing micro ribonucleic acid (miRNAs) expressed in cardiomyocytes to infect mice, which served as a model to study the etiology of influenza-associated cardiac pathology. Study: Influenza virus replication in cardiomyocytes drives heart dysfunction and fibrosis. Image Credit: pinkeyes/Shutterstock Background Several studies … Read more
Since the initial global outbreak of severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2), the causal agent of the coronavirus disease 2019 (COVID-19) pandemic, a continuous evolution of the virus has been observed. The emergence of new SARS-CoV-2 variants, which have been classified as variants of concern (VOC) and variants of interest (VOI), has reduced the efficacy … Read more
A nanotech imaging device, tiny enough to fit on a smartphone camera lens, has the potential to make the diagnosis of certain diseases accessible and affordable for people in rural and remote regions, say Australian scientists who developed it. The COVID-19 pandemic has brought diagnostics into sharp focus and the World Health Organization has called … Read more
In a recent study published in the journal Vaccinesresearchers revealed how severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) Omicron escapes neutralizing antibodies (nAbs). Two days after it was first reported on November 24, 2021, the World Health Organization (WHO) designated SARS-CoV-2 Omicron as a variant of concern (VOC). The WHO estimated a potentially higher risk of … Read more
A recent study posted to the medRxiv* preprint server demonstrated that autoantibody levels rise following acute severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and remain to be elevated for about six months. Study: Longitudinal analysis reveals elevation then sustained higher expression of autoantibodies for six months after SARS-CoV-2 infection.
