Optogenetics is a recently developed technique that can control cellular functions by illuminating lights to the cells in which light-sensitive proteins are expressed by gene transfer.

Artificial intelligence can detect serious eye disease in diabetic patients

Rss Feed - Mon, 07/06/2020 - 19:51
Results from the largest study of artificial intelligence use in the English Diabetic Eye Screening Programme (DESP), have shown that the technology can accurately detect serious eye disease among those with diabetes (retinopathy) and could halve the human workload associated with screening for diabetic eye disease, saving millions of pounds annually.

Study examines elderly people's attitudes and compliance to COVID-19 preventive measures

Survey results from 27 countries suggest that, despite their increased risk of severe illness due to COVID-19, elderly people are not more willing to isolate when asked to, and are not more compliant with several COVID-19 preventive measures.

Asthma does not appear to increase the risk for a person contracting COVID-19 or influence its severity, according to a team of Rutgers researchers.

Cell 'membrane on a chip' could help test potential drug candidates for COVID-19

Rss Feed - Mon, 07/06/2020 - 11:25
Researchers have developed a human cell 'membrane on a chip' that allows continuous monitoring of how drugs and infectious agents interact with our cells, and may soon be used to test potential drug candidates for COVID-19.

Researchers detect "biologically relevant" AMH levels in human hair samples

The prospect of a non-invasive test of ovarian reserve is a little closer following results from a study showing that measurement of a fertility hormone can be accurately taken from a sample of human hair.

Oxford COVID-19 vaccine trials move to stage 3 human trials

Rss Feed - Mon, 07/06/2020 - 07:33
The technical name of the vaccine is ChAdOx1 nCoV-19 (AZD1222), as it is made from a virus called ChAdOx1, which is a weakened and non-replicating version of a common cold virus (adenovirus). The vaccine has been engineered to express the SARS-CoV-2 spike protein.

Research suggests protective effect of influenza vaccine against COVID-19 severity and mortality

Rss Feed - Mon, 07/06/2020 - 06:36
A new study involving over 92,000 patients with COVID-19 in Brazil shows that the odds of severe disease, ventilatory support requirement, and death are reduced with a recent trivalent flu vaccine. This seems to indicate that these vaccines should be used as widely as possible to reduce the risk of severe COVID-19, especially among high-risk groups. The study is published on the preprint server medRxiv* in June 2020.
