Innovative protocol that processes saliva samples before testing may improve COVID-19 detection

The collection of nasopharyngeal swab (NPS) samples for COVID-19 diagnostic testing poses challenges including exposure risk to healthcare workers and supply chain constraints. Saliva samples are easier to collect but can be mixed with mucus or blood, and some studies have found they produce less accurate results.

The potential of mRNA vaccines for a wide range of diseases

A new review article published in the journal Briefings in Functional Genomics focuses on the general characteristic features and mechanisms of mRNA vaccines. Further, this review has summarized the current progress of mRNA vaccines that have been developed for wide-ranging diseases, including COVID-19 disease.

MIT researchers develop a molecular assay to detect sub-picomolar levels of the SARS-CoV-2's receptor-binding domain

A team of researchers at MIT has developed a molecular assay to detect sub-picomolar levels of the SARS-CoV-2’s spike protein receptor-binding domain (S-RBD) using computationally validated peptide beacons in a single-step detection through the production of a fluorescence signal.

Researchers review environmental risk assessments for recombinant COVID-19 viral vector vaccines

In a recent review, published in the journal Vaccines, researchers in Belgium look at the recombinant viral vector-vaccine candidates that are primarily against SARS-CoV-2 still in development and discuss their features from an environmental risk point of view.

Researchers detect Zika virus RNA in free-ranging African bats

A team of Colorado State University scientists, led by veterinary postdoctoral fellow Dr. Anna Fagre, has detected Zika virus RNA in free-ranging African bats. RNA, or ribonucleic acid, is a molecule that plays a central role in the function of genes.

Oligo DNA improves differentiation of skeletal muscles exacerbated by diabetes

Skeletal muscle is the largest organ in the body that accounts for 30 to 40% of body weight and is responsible for multiple functions such as energy metabolism and heat production.

CASdetec: new CRISPR-based SARS-CoV-2 detection platform detects nucleic acids with high sensitivity and specificity

To add to existing CRISPR-based nucleic acid detection protocols, a team of researchers recently established a new SARS-CoV-2 detection protocol based on their previously reported platform - CDetection (Cas12b-mediated DNA detection). They combined nucleic-acid amplification methods and sample treatment protocols with CDetection and established an integrated nucleic acid detection platform called CRISPR-assisted detection or CASdetec. CASdetec has a detection limit of 1×104 copies/mL for SARS-CoV-2 pseudovirus, without any observed cross-reactivity.

Intranasal COVID-19 therapeutic shows promise in preclinical trials

Researchers from the US and Denmark recently described a novel therapeutic option that targets the SARS-CoV-2 ribonucleic acid (RNA) using locked nucleic acid antisense oligonucleotides (LNA ASOs). They identified an LNA ASO that binds to the 5’ leader sequence of SARS-CoV-2 ORF1a/b. This disrupts a highly conserved stem-loop structure with nanomolar efficacy and inhibits viral replication in host cells.

Protein-based vaccines against SARS-CoV-2 may provide advantages over mRNA-based vaccines

Researchers in the UK have developed a protein-based subunit vaccine directed against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that could serve as an alternative to the mRNA-based vaccines currently approved for protecting against coronavirus disease 2019 (COVID-19).

New imaging technique helps reveal the best antibodies for COVID-19 detection

Vaccines are turning the tide of the pandemic, but the risk of infection is still present in some situations. If you want to visit a friend, get on a plane, or go see a movie, there is no highly accurate, instant test that can tell you right then and there whether or not you have a SARS-CoV-2 infection.

Nanotechnology and COVID-19 diagnosis and treatment

The development of nano-biosensors and nanoparticle-based vaccines and medicines has opened a new path toward better management of the coronavirus disease 2019 (COVID-19) pandemic. In a recently published article in the journal ACS Biomaterials Science & Engineering, scientists have reviewed recent advancements in nanotechnology-based diagnostic and therapeutic interventions against human coronaviruses.

A magnetofluidic platform for SARS-CoV-2 variant and respiratory pathogen detection

Recent research published on the medRxiv* server has developed a portable, magnetofluidic cartridge platform, for automated PCR testing in <30 min, for rapid multiplexed screening of pathogens. A multidisciplinary team of researchers at Johns Hopkins University and the Johns Hopkins University School of Medicine developed these cartridges for multiplexed detection of SARS-CoV-2 with distinctive variant mutations or with Influenza A and B.

CNIO researchers unravel why motor neurons die in ALS patients

In Amyotrophic Lateral Sclerosis (ALS), the progressive death of neurons that control body movement leads to paralysis of muscles in the limbs and gradually of the whole body, which ultimately makes it impossible to breathe. ALS is currently untreatable, and its cause is unknown.
