Simple at-home taste test could predict duration and severity of SARS-CoV-2 symptoms

A JAMA Network Open research paper published today (26 May 2021) by Doctorpedia contributor Henry P. Barham, M.D correlating an association between the bitter taste receptor phenotype and clinical outcomes among patients with COVID-19 has confirmed that a simple at-home taste test could be a gamechanger in predicting duration and symptom severity of the virus.

Glycosylation a significant element in SARS-CoV-2 infection and vaccine design, says study

A new study by researchers from Taiwan and the US suggests that the removal of unnecessary glycans from spike glycoprotein of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) exposes highly conserved sequences and opens the door for the development of broadly protective vaccines against the virus and its variants.

Will emerging SARS-CoV-2 variants affect T cell immunity? A meta-analysis

New research by a team of scientists at The Hong Kong University of Science and Technology sheds light on the epitopic targets of SARS-CoV-2 by T cells in COVID-19 convalescents. The team’s findings suggest that the epitopes targeted by T cells during infection may not be affected by the emergence of SARS-CoV-2 variants.

Researchers discover cross-reactive coronavirus antibody triggered during COVID-19 infection

Even before the COVID-19 pandemic, most people in the United States already had been sick with a coronavirus, albeit a far less dangerous one.

New biomarker could be used to determine resistance of ovarian cancer to platinum chemotherapy

Epithelial ovarian cancer (EOC) is the most common lethal gynaecological cancer. Ovarian cancer is usually treated with platinum-based chemotherapy; however, a significant number of patients are resistant to such treatments and relapse soon afterwards.

Pfizer-BioNTech COVID-19 vaccine may not be associated with adverse effects on fertility and breastfeeding, says study

A recent study by researchers in Singapore shows the absence of evidence for adverse effects on fertility or the presence of the vaccine mRNA (messenger ribonucleic acid) in breast milk, following the administration of the Pfizer BNT162B2 COVID-19 vaccine. This supports efforts to prevent the spread of false information about the effects of the vaccine.

Study shows CoronaVac to have high seroconversion rate after 40 days

Researchers from the Federal University of Paraná, Brazil, looked into the seroconversion rate after vaccination with the CoronaVac. Using immunoassays, they measured the immunoglobulins (IgG) for anti-nucleocapsid protein (anti-N) antibodies and anti-spike-1 (anti-S1) protein antibodies.

Vagus nerve stimulation may be a potential adjunct therapy for COVID-19

COVID-19 was initially described as lung inflammation, or pneumonia, in older adults. However, we now know that SARS-CoV-2 infections can cause a wide range of symptoms in people of all ages, ranging from no symptoms at all to systemic inflammation and even death.

New porous biomaterial could help in bone repair

Scientists at Nanyang Technological University, Singapore (NTU Singapore) have developed a new biomaterial made entirely from discarded bullfrog skin and fish scales that could help in bone repair.

Study sheds new light on complex dynamics involved in microbial infections

Included in the vast fallout stemming from the COVID-19 pandemic, scientists are paying closer attention to microbial infections and how life forms defend against attacks from pathogens.

Salmonella bacteria colonize the gut using intestinal epithelial cells

The immune system's attempt to eliminate Salmonella bacteria from the gastrointestinal (GI) tract instead facilitates colonization of the intestinal tract and fecal shedding, according to National Institutes of Health scientists.

Intensity and duration of SARS-CoV-2 immunity may depend on ABO blood group

A team of scientists from Canada and Spain recently evaluated the durability of antigen-specific immune responses in COVID-19 recovered individuals. They have also identified potential host factors associated with robust and long-lasting anti-SARS-CoV-2 immunity.

An exploratory study of T-cell and antibody responses after COVID-19 mRNA vaccination

Recent COVID-19 investigations have found that up to half of immunocompromised individuals struggle to produce antibodies after receiving their severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccinations.

Immunologists decode T cell responses that occur during COVID-19 infection

An international team of researchers from the Institute for Research in Biomedicine, affiliated to the Università della Svizzera italiana, has deciphered, at single cell resolution, the T cell responses occurring during COVID-19 infection.

Previous H3N2 influenza A infection may explain some cases of severe COVID-19

According to research from the University of California, some cases of severe coronavirus disease 2019 (COVID-19) may be related to the immunological memory of previous H3N2 influenza A infection.

Study shows how rare but serious post-COVID-19 complication develops in children, adolescents

A multidisciplinary team from MassGeneral Hospital for Children (MGHfC), Brigham and Women's Hospital and other institutions have identified the mechanism of how an extremely rare but serious post-COVID-19 complication develops in children and adolescents.

Study attempts to standardize humoral immune Correlates of Protection (CoP) in COVID-19

A new study aims to identify antibody-based biomarkers associated with the humoral immune response that could be a standard CoP candidate for COVID-19. Further, standardization of research methods to measure these biomarkers has also been conducted.
