Antibodies to SARS-CoV-2 spike protein and RBD detected in saliva of mRNA-vaccine recipients

A team of researchers from the US and the Netherlands recently reported that antibodies to the spike protein and the RBD are detected in saliva samples from healthcare workers vaccinated with mRNA vaccines.

SARS-CoV-2 is extremely sensitive to type I IFN pre-treatment, study finds

Researchers have found that SARS-CoV-2 is extremely sensitive to type I IFN pre-treatment. Therefore, strategies such as focusing on limiting the production of IFN, rather than its function, could restrict the mechanism of SARS-CoV-2 that increases its viral load with delayed or absent symptoms.

Pooling COVID-19 tests to detect future outbreaks

How could pooling SARS-CoV-2 tests help to detect future viral outbreaks? News-Medical spoke to Dr. Jean-François Rupprecht to find out more.

New book provides general introduction about COVID-19, history, and diagnosis

Recently, a novel coronavirus (2019-nCoV) emerged in China and rapidly spread worldwide. It is declared an ongoing outbreak as a global public health emergency by the World Health Organization (WHO).

New study sheds light on cancer metastasis

Breast cancer is harmful enough on its own, but when cancer cells start to metastasize -- or spread into the body from their original location -- the disease becomes even more fatal and difficult to treat.

Scientists increase potency of HIV-1 antibody, identify new ways to develop vaccines

Much like coronavirus, circulating HIV-1 viruses mutate into diverse variants that pose challenges for scientists developing vaccines to protect people from HIV/AIDS.

COVID-19 mRNA vaccines can reduce risk of asymptomatic COVID-19 infection

Ten days after receiving a second dose of a messenger RNA, or mRNA, vaccine for COVID-19, patients without COVID-19 symptoms are far less likely to test positive and unknowingly spread COVID-19, compared to patients who have not been vaccinated for COVID-19.

Exposure to COVID-19 can cause rare but life-threatening pediatric condition

Exposure to SARS-Co-V2, the virus that causes COVID-19, can put otherwise healthy children and adolescents at risk for Multisystem Inflammatory Syndrome in Children (MIS-C), a rare but possibly life-threatening pediatric condition that can cause severe inflammation in organs like the heart, brain, lungs, kidneys and gastrointestinal system.

New approach could treat infertility caused by abnormal GnRH secretion

Reports suggest that at least 25% of ovarian disorders are due to dysfunction of the brain mechanism in the hypothalamus that controls the gonadotropin-releasing hormone (GnRH), which is a molecule that governs the reproductive function in men and women by regulating the release of a range of reproductive hormones into the body, particularly gonadotropins, from the pituitary gland, which is located underneath the brain.

Spike protein mutations in SARS-CoV-2 variants help resist antibody neutralization

Researchers based in Beijing and Shenzhen, China, report that they have identified mutations in the spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) that may allow variant strains to avoid neutralization by monoclonal antibodies and convalescent blood plasma.

N501Y mutation in SARS-CoV-2 responsible for increased viral transmission

Researchers at the University of Texas, USA, have confirmed the specific mutation in the B.1.1.7 variant of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of coronavirus disease 2019 (COVID-19), has allowed for it to be more transmissible than the ancestral strain. The N501Y substitution is one of 8 spike protein substitutions present in the UK variant and has also appeared convergently in the Brazil (P.1) and South Africa (B.1.351) variants.

Structure and function of locked conformation of the SARS-CoV-2 spike protein identified

A new preprint research paper, posted to the bioRxiv* server, uncovered more information on the different structural conformations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The findings suggest the spike protein turns into a locked state to stabilize the spike protein during virus egress.

Delaying second dose of Pfizer-BioNTech SARS-CoV-2 vaccine may be feasible in some cases

Researchers in Spain have conducted the most extensive study to date investigating the effectiveness of vaccinating healthcare workers with a single dose of the Pfizer-BioNTech vaccine to protect against coronavirus disease 2019 (COVID-19).

Study addresses glycosylation concerns in SARS-CoV-2 vaccine design

An international team of researchers has found that glycosylation patterns are conserved across the native spike protein of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – the agent that causes coronavirus disease 2019 (COVID-19) – and the recombinant spike proteins made in laboratories for use in vaccines.

Early tracheotomy shortens ICU stay and lowers risk of ventilator-associated pneumonia

Surgically opening the windpipe, or trachea, within the first seven days of the start of mechanical ventilation decreases the time patients spend on ventilators, shortens their ICU stay and lowers their risk of ventilator-associated pneumonia, according to a systematic review published Thursday (March 11) in JAMA Otolaryngology-Head & Neck Surgery.
