Further evidence does not support hydroxychloroquine for patients with COVID-19 Posted: 15 May 2020 02:44 PM PDT The anti-inflammatory drug hydroxychloroquine does not significantly reduce admission to intensive care or death in patients hospitalized with pneumonia due to COVID-19, finds a study from France. And a randomized clinical trial from China shows that hospitalized patients with mild to moderate persistent covid-19 who received hydroxychloroquine did not clear the virus more quickly than those receiving standard care. |
COVID-19 infection control, radiographer protection in CT exam areas Posted: 15 May 2020 10:54 AM PDT Radiologists from Shanghai discuss modifying exam process and disinfecting exam room, while outlining personal protection measures during the coronavirus disease outbreak. |
The dreaming brain tunes out the outside world Posted: 15 May 2020 10:19 AM PDT Scientists have shown that the brain suppresses information from the outside world, such as the sound of a conversation, during the sleep phase linked to dreaming. This ability could be one of the protective mechanisms of dreams. |
Blood clotting abnormalities reveal COVID-19 patients at risk for thrombotic events Posted: 15 May 2020 10:19 AM PDT A new article highlights early research on blood clotting evaluation work that may help identify and treat dangerous complications of the infection. |
Model of critical infrastructures reveals vulnerabilities Posted: 15 May 2020 08:56 AM PDT Researchers developed a computer simulation that revealed beef supply chain vulnerabilities that need safeguarding -- a realistic concern during the COVID-19 pandemic. |
Heart attacks, heart failure, stroke: COVID-19's dangerous cardiovascular complications Posted: 15 May 2020 08:56 AM PDT A new guide from emergency medicine doctors details the potentially deadly cardiovascular complications COVID-19 can cause. |
Antiviral drug can speed up recovery of COVID-19 patients, study shows Posted: 15 May 2020 07:39 AM PDT Research shows for the first time that interferon-alpha2b improves virus clearance and decreases levels of inflammatory markers in COVID-19 patients. |
Social good creates economic boost Posted: 15 May 2020 07:39 AM PDT As unemployment rates skyrocket around the world due to the COVID-19 pandemic, a new study out of Australia and Sweden has found social venture start-ups not only alleviate social problems but are also much more important for job creation than previously thought. |
Quantifying the impact of interventions in COVID-19 pandemic Posted: 15 May 2020 07:39 AM PDT Since the beginning of March, public life in Germany has been severely restricted due to the coronavirus pandemic. Following the encouraging decline in the number of new cases of COVID-19, the debate on the effectiveness of interventions taken to date and on further relaxation of the restrictions is meanwhile gaining momentum. |
Detailed analysis of immune response to SARS-CoV-2 bodes well for COVID-19 vaccine Posted: 15 May 2020 06:20 AM PDT A new study documents a robust antiviral immune response to SARS-CoV-2 in a group of 20 adults who had recovered from COVID-19. The findings show that the body's immune system is able to recognize SARS-CoV-2 in many ways, dispelling fears that the virus may elude ongoing efforts to create an effective vaccine. |
Malaria parasite ticks to its own internal clock Posted: 14 May 2020 11:35 AM PDT Researchers have long known that all of the millions of malaria parasites within an infected person's body move through their cell cycle at the same time. They multiply in sync inside red blood cells, then burst out in unison every few days. But how the parasites keep time was unclear. Now, a study finds that malaria has its own internal clock that causes thousands of genes to ramp up and down at regular intervals. |
SARS lessons for COVID-19 vaccine design Posted: 14 May 2020 08:58 AM PDT Important lessons learned from the Severe Acute Respiratory Syndrome (SARS) outbreak of 2002-2003 could inform and guide vaccine design for COVID-19, according to a new article. |
Global spread of the multi-resistant pathogen Stenotrophomonas maltophilia Posted: 14 May 2020 08:57 AM PDT Researchers have found a remarkable global spread of strains of a multi-resistant bacterium that can cause severe infections -- Stenotrophomonas maltophilia. The study provides for the first time a systematic understanding of the global phylogeny of S. maltophilia strains and shows ways to efficiently monitor the pathogen using a genomic classification system. |
High calcium levels in mitochondria linked to neuronal death in Alzheimer's disease Posted: 13 May 2020 05:18 AM PDT For the first time, using a mouse model of Alzheimer's disease, scientists have documented a link between raised levels of calcium in mitochondria and neuronal death in the living brain. |
Mucus breakthrough could help patients breathe easy Posted: 13 May 2020 05:17 AM PDT New insights into the molecular mechanisms driving mucus viscosity were have been discovered. A discovery about how mucus thickness is regulated could help to improve airway-clearing treatment options for people with chronic respiratory conditions such as asthma, cystic fibrosis and chronic obstructive pulmonary disease (COPD). |
Novel antiviral targeted drug for nasopharyngeal cancer Posted: 12 May 2020 04:00 PM PDT A research team has developed a novel anti-Epstein-Barr virus (EBV) drug that can selectively disrupt a viral protein produced by EBV, leading to the shrinkage of tumors caused by the virus. It is the first known agent to successfully target the virus and disturb its latency in tumor cells in this way. |
Physically demanding jobs linked to shorter working lives and more sick leave Posted: 12 May 2020 03:59 PM PDT Physically demanding jobs are linked to shorter working lives, more sick leave and unemployment than jobs that don't rely on muscle and brawn, suggests a large long term study of Danish workers in hundreds of different types of jobs. |
