Change in glutathione reductase lowers inflammation in present-day humans

Very few proteins in the body have a change that makes them unique compared to the corresponding proteins in Neanderthals and apes.

Scientists estimate transmission advantage of Omicron over Delta variant as +105%

Researchers use statistical models to assess the transmission of the SARS-CoV-2 Omicron using variant-specific screening tests and genome sequencing.

Brain volume measurements show differences between conventional and ultrafast 3D T1W MRI sequences

According to an article in ARRS' American Journal of Roentgenology, brain volume measurements in memory-impaired patients show significant differences and systematic biases between conventional and ultrafast 3D T1-weighted (T1W) MRI sequences.

Analyzing cell-free RNA could reliably predict preeclampsia

Imaging techniques such as ultrasound technologies and minimally invasive procedures are powerful tools for assessing pregnancy health and progression.

First-responder cells launching the repair after heart attack promote inflammation overdrive

First-responder cells launching the repair after a heart attack are so frantic about fixing the damage that they promote more inflammation than necessary, new research in mice suggests.

Study defines a novel way to identify potential new interventions for autism

Researchers from King's College London have shown that there are variations in how a brain chemical called GABA regulates the processing of visual stimuli.

New approach could offer a more accurate way to evaluate donor kidney quality

A new way to evaluate the quality of kidneys before transplantation could one day help increase the number of usable donor kidneys.

Study pinpoints brain networks behind speech planning

A new study has identified a brain circuit that is active while we plan our spoken replies during conversation.

Integrin/TGF-β1 inhibitors highly effective in attenuating COVID-19 severity

New study results suggest that integrin inhibitors have the potential to both prevent infection with SARS-CoV-2, including the Delta and Omicron variants, and to decrease TGF-β levels, resulting in a decrease in COVID-19 severity, hospitalization, and death, especially in vulnerable and unvaccinated populations.

Researchers develop new tool to predict pre-eclampsia

A study of pregnant women's blood RNA has found specific molecular profiles that identify women at risk of pre-eclampsia. These insights can identify complications before a woman experiences symptoms.

Exploring SARS-CoV-2-like viruses to mitigate the risk of zoonotic transmission to humans

In a new study, a team of researchers developed a genetic assay to evaluate several clade 2 and clade 3 receptor-binding domains (RBD) of spike (S) protein sequences of genus sarbecovirus.

Study findings suggest spread of Omicron can be ascribed to immune evasiveness rather than an increase in transmissibility

Researchers investigate the household transmission of the Omicron VOC and increased immune evasiveness of both the Omicron and Delta variants

Hospitalization and death associated with SARS-CoV-2 Omicron variant compared to Delta variant

Researchers evaluate the rates of hospitalization and deaths associated with the SARS-CoV-2 Omicron variant as compared to the Delta variant.

Public attitudes to the COVID-19 pandemic during the emergence of the Omicron variant

Researchers from Swansea University have been investigating public attitudes to the pandemic.

Exploring vaccine-induced cellular immunity against SARS-CoV-2 Omicron variant

In a new study, researchers determined CD8+ and CD4+ T cell responses against the SARS-CoV-2 Omicron variant in 51 individuals vaccinated with the messenger ribonucleic acid (mRNA)-based Pfizer and adenovirus vector-based Johnson & Johnson vaccines.

Comparison of the mutational profile of Omicron with other SARS-CoV-2 lineages

Researchers from nference labs in Massachusetts have been examining the origins of a particular mutation in the Omicron variant.

5 Jan 2022

Statistical analysis reveals less severe COVID-19 outcome due to Omicron variant

A new study demonstrated that in the US, the COVID-19 cases arising after the emergence of the SARS-CoV-2 Omicron variant showed reduced severity of infection than in the cases recorded in previous time points (during the Delta variant outbreak).

Erectile dysfunction medication found to intensify abdominal aortic aneurysms in mice

In a laboratory study in mice, sildenafil, a commonly used erectile dysfunction medication, was found to worsen abdominal aortic aneurysms, indicating additional research may be needed to determine if the medication may have the same effect on people, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Efficacy of rapid antigen diagnostic tests for the detection of infectious individuals at mass gatherings

New study findings show that incidence data often underestimates the prevalence of COVID-19 infectious individuals at a given point in time in a population.

COVID-19 mRNA vaccines offer protection against Omicron variant in pregnancy

A new study provides insights into the persistence of extra-neutralizing properties of mRNA vaccine-induced antibodies resulting in protection against the Omicron variant of SARS-CoV-2.
