PCR Biosystems launches new kit for ultra-sensitive, high-throughput detection of SARS-CoV-2

PCR Biosystems, the UK-based PCR experts, today announced the launch of qPCRBIO Probe 1-Step Virus Detect, a high-concentration 4x RT-qPCR kit designed specifically for ultra-sensitive, high-throughput detection of viral RNA sequences, including SARS-CoV-2.

WVU researchers develop new diagnostic and antibody tests for COVID-19

COVID-19 tests are in short supply. The companies that make the necessary chemicals--called reagents--can't keep up with demand. But researchers at West Virginia University are developing new tests on their own to identify who has COVID-19 now and who had it in the past but recovered.

Irradiation with UV light kills SARS-CoV-2

Researchers in Italy have found that it is possible to completely inactivate severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) using short-wavelength UV (UV-C) irradiation.

New strategy may facilitate development of multi-epitope peptide vaccine against SARS-CoV-2

By combining T and B lymphocyte analysis with manufacturability heuristic, researchers from the US and Germany proposed a set of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccine peptides to use in subsequent animal studies and clinical trials. Their paper is currently available on the bioRxiv preprint server.

Human protein plays key role in transcription and genome integrity

Researchers from the University of Seville and Cabimer discover that the UAP56/DDX39B protein remove DNA-RNA hybrids from the genome

Discharge-ready patients still breathing out SARS-CoV-2 particles, finds study

In just five months, the COVID-19 paralyzed huge cities, confined billions to their homes, and brought economic activity to a standstill in much of the world. Tens of thousands of patients became critically ill, overwhelming healthcare facilities. Even as many recovered and were ready to go home, a new study published in May 2020 on the preprint server medRxiv reports that a significant number of patients ready to go home still have virus particles in their exhaled breath.

New COVID-19 test speeds up access to urgent care

The first analysis of a new point-of-care "nucleic acid test" for SARS-CoV-2 in a UK hospital setting shows these machines dramatically reduce time spent on COVID-19 'holding' wards - allowing patients to be treated or discharged far quicker than with current lab testing set-ups.

Study reveals how essential SARS-CoV-2 protein can be stabilized and scaled for production

A research group from the University of Texas in Austin described a high-yield production of a stabilized severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spike protein (S-protein) that may accelerate the development of vaccines and diagnostic tests. This methodological 'tour de force' paper is currently available on the bioRxiv* preprint server.

No specific COVID-19-linked lesions found despite extensive organ injury

A recent paper published online on the preprint server medRxiv in May 2020 reports autopsy results on COVID-19 patients. The paper concludes that there were no specific hallmark lesions of COVID-19 in any of the many organs found to be injured by the infection in patients who died of the disease.

Scientists track SARS-CoV-2 in wastewater

Epidemiologist David Larsen, from Syracuse University and microbiologists Hyatt Green, from the College of Environmental Science and Forestry and Frank Middleton, from Upstate Medical University are lead members of a multi-institution research project that is expected to have global application in future efforts to track and contain Sudden Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2), the virus that causes Coronavirus Disease 2019 (COVID-19).

Toshiba and Shinshu University jointly develop a 'tumor-tropic liposome technology' for gene therapy

Toshiba Corporation and a team led by Professor Yozo Nakazawa at the Department of Pediatrics, Shinshu University, have together developed a “tumor-tropic liposome technology” for gene therapy. The technology uses unique, nano-sized biodegradable liposomes developed by Toshiba to accurately and efficiently deliver therapeutic genes to targeted cancer cells, and achieves safer gene delivery than viruses used as carriers.

SARS-CoV-2 RNA in blood tests not associated with infectious virus

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has challenged hospitals and laboratory services worldwide. Diagnostic testing for SARS-CoV-2 initially lagged but is now primarily based on the use of reverse transcriptase-polymerase chain reaction (RT-PCR) to detect viral nucleic RNA in the samples. However, viral RNA has also been reported in several small series of cases, though its significance and frequency remain unclear.

EKF secures COVID-19 novel sample collection kit manufacturing and supply contracts

EKF Diagnostics, the global in vitro diagnostics company, announces it has secured new contracts for the manufacture and supply of a novel, patented sample collection device which allows COVID-19 samples to be rapidly inactivated in the collection tube, avoiding contamination and preserving RNA without need for refrigeration.

Study evaluates the effectiveness of interferon beta 1b in COVID-19 pneumonia

As the world struggles to overcome the current COVID-19 pandemic with non-pharmacological interventions, in the absence of an effective drug or vaccine, existing immunomodulators are being repurposed. A new study published on the preprint server medRxiv* in May 2020 shows no clinical benefit to the use of one such drug, called interferon beta 1b (IFN beta1b).

Saliva testing allows quick, accurate and non-invasive SARS-CoV-2 detection

Saliva is one of the ways people can transmit the novel coronavirus to others, but it may also help combat coronavirus disease (COVID-19). Scientists are now looking into using saliva to test for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent for COVID-19 disease.

Experts urge further improvements in COVID-19 testing to increase speed and availability

In an important, comprehensive, and timely review, an expert team from the University of California Berkeley details the methodologies used in nucleic acid-based tests for detecting the presence of SARS-CoV-2, the virus that causes COVID-19.

Viral shedding seen in plasma donors who have recovered from COVID-19

Researchers from the University of Wisconsin-Madison have found that plasma donors who have recovered from the deadly COVID-19 infection were still shedding viral RNA. This could be significant they write in their article titled, “Prolonged viral RNA shedding after COVID-19 symptom resolution in older convalescent plasma donors,” that is published on the preprint server Medrxiv* prior to peer review.
