Undamaged neurons do not change their function after stroke, mice study shows

A study from UCLA neurologists challenges the idea that the brain recruits existing neurons to take over for those that are lost from stroke. It shows that in mice, undamaged neurons do not change their function after a stroke to compensate for damaged ones.

A study of circulating biomarkers in hospitalized patients infected with SARS-CoV-2 alpha variant

Now, a new study published on the medRxiv* preprint server proposes a rapid method to identify the mutations in B.1.1.7 (N501Y mutation and H69/V70 deletion) and the impact of this variant on various biomarkers in hospitalized patients. This is the first study that correlates the biomarker levels to SARS-CoV-2 variants.

Natural compound myricetin shows antiviral potential against SARS-CoV-2

New findings from a team of Chinese researchers suggest natural compounds — specifically the flavonoid myricetin — could also be a potential drug candidate for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection.

Study examines SARS-CoV-2 replication in cells using super-resolution microscopy

Despite tremendous efforts by the global scientific community to curb the spread of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), by developing more efficient testing protocols, therapies, and vaccines at a rapid pace, relatively little is known about the dynamics of SARS-CoV-2 replication within cells.

Differential localization may explain different physiological functions of receptors

In the heart there are two different subtypes of beta-adrenergic receptors - beta1 and beta2 - which are activated by the stress hormones adrenaline and noradrenaline.

Novel calibration process for super-resolution microscopy

Light--and all waves--can bend around the corners of obstacles found along its path. Because of this phenomenon, called diffraction, it is impossible to focus light onto a spot that is smaller than half its wavelength.

Researchers develop new imaging technique for studying nanoscale coronavirus-host interactions

Lei S. Qi of Stanford University, California, and colleagues published research showing a potential framework to better characterize coronaviruses' biology. While most high-resolution imaging techniques show the life cycle of coronaviruses, identifying viral or host proteins and genomes remains poorly understood. Their results use multi-color super-resolution imaging allows them to study nanoscopic parts of the coronavirus, including RNA.

New digital tool makes the analysis of microscopy images much easier

Information technology can make life easier in many areas - including research. In medicine, for example, it is still standard practice to evaluate microscopy images of tissue sections by hand. This is used, for example, to assess how many cancer cells are in a lymph node.

New insight into how platelets help resolve bacterial lung inflammation

Treating patients with acute respiratory failure is a constant challenge in intensive care medicine. In most cases, the underlying cause is lung inflammation triggered by a bacterial infection or - more rarely, despite being frequently observed at present due to the corona pandemic - a viral infection.
