Thu, 07/02/2020 - 21:17
For military veterans suffering from post-traumatic stress disorder (PTSD), symptoms such as anxiety, anger and depression can have a devastating impact on their health, daily routine, relationships and overall quality of life.

Study identifies a promising way to delay the onset of Alzheimer's disease

Thu, 07/02/2020 - 21:06
Currently we are facing a dementia epidemic, estimations showing that by 2050 approximately 131 million people will be affected. Every 7 seconds a patient is diagnosed worldwide.

New study supports a causal relation of SARS-CoV-2 with COVID toes

Thu, 07/02/2020 - 20:51
There's considerable controversy over whether "COVID toes"—red sores or lesions on the feet and hands in children and young adults—are truly caused by COVID-19.

Studies show how individual cells maintain their internal clocks

Thu, 07/02/2020 - 20:23
Two new studies led by UT Southwestern scientists outline how individual cells maintain their internal clocks, driven both through heritable and random means.

Researchers investigate decision-making processes implemented by Swiss government during COVID-19 crisis

Thu, 07/02/2020 - 20:13
At the beginning of the coronavirus crisis, Switzerland declared a four-month-long state of emergency, the country's longest since the Second World War.

Researchers identify mosquito species that could transmit malaria

Thu, 07/02/2020 - 20:02
During collections for a study to map the distribution of mosquito species in Finland, Anopheles daciae, a species previously not known to occur in Finland was found from several locations in the south of the country.

Novel method shows how cell membranes are damaged by 'Parkinson's protein'

Thu, 07/02/2020 - 12:53
In sufferers of Parkinson's disease, clumps of α-synuclein (alpha-synuclein), sometimes known as the 'Parkinson's protein', are found in the brain.

Study: Oats and rye brans reduce weight gain, hepatic inflammation

Thu, 07/02/2020 - 12:44
In a newly published experimental study, the consumption of dietary fibre from oat and rye brans supported the growth of beneficial gut microbiota, which in turn ameliorated cholesterol metabolism, enhanced gut barrier function and reduced hepatic inflammation.

Researchers outline checklist for implementation of COVID-19 communication strategies

Thu, 07/02/2020 - 11:46
The COVID-19 pandemic has introduced unique challenges for public health practitioners and health communicators that warrant an expansion of existing health communication principles to take into consideration.

Passive stretching can improve blood flow, prevent stroke and diabetes

Thu, 07/02/2020 - 11:46
New research published today in The Journal of Physiology shows that 12 weeks of easy-to-administer passive stretching helps improve blood flow by making it easier for your arteries to dilate and decreasing their stiffness.

ACTIV group uses controlled human infection models to support SARS-CoV-2 vaccine development

Thu, 07/02/2020 - 11:44
In a Perspective for the New England Journal of Medicine, members of the National Institutes of Health's Accelerating COVID-19 Therapeutic Interventions and Vaccines (ACTIV) Vaccines Working Group assess practical considerations and prerequisites for using controlled human infection models (CHIMs), which can be used for human challenge studies, to support SARS-CoV-2 vaccine development.

Oxidized charcoal nanoparticles can help treat COVID-19 patients

Thu, 07/02/2020 - 11:44
Artificial enzymes made of treated charcoal could have the power to curtail damaging levels of superoxides, radical oxygen ions that are toxic at high concentrations.

Novel microbiome-based diagnostic tool can identify liver fibrosis, cirrhosis

Thu, 07/02/2020 - 11:44
Chronic liver disease represents a major global public health problem affecting an estimated 844 million people, according to the World Health Organization. It is among the top causes of mortality in Australia, the UK and the United States.

Structure of the full SARS-CoV-2 RNA genome in infected cells

Thu, 07/02/2020 - 11:37
The current COVID-19 pandemic caused by a single-stranded RNA virus, thought to have jumped across species barriers to infect humans, has spread rapidly across the globe infecting over 10 million individuals. The virus, now known as the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is the causative agent of COVID-19 disease. COVID-19 disease is a respiratory illness where symptoms can range from very mild to severe and include fever, coughing, a sore throat, and shortness of breath.

SARS-CoV-2 infection modeling in iPSC-derived type 2 cells

Thu, 07/02/2020 - 10:26
The most fatal form of COVID-19 disease is acute respiratory distress syndrome (ARDS), caused by direct viral injury as well as indirect noxious effects caused by cytotoxic chemicals and inflammatory processes. A new study published on the preprint server bioRxiv* in June 2020 shows that this is partly due to the rapid onset of inflammation caused by the infection of type 2 alveolar cells with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).

Novavax SARS-CoV-2 vaccine candidate shows promise in animal models

Thu, 07/02/2020 - 10:07
A new study published on the preprint server bioRxiv in June 2020 shows that a candidate spike protein vaccine can induce neutralizing antibodies, antiviral T cell responses, and protection against infection.

Repurposed drug for acute lung injury in COVID-19

Thu, 07/02/2020 - 09:31
Now, a new study addresses the possible use of an FDA-approved monoclonal antibody, called fostamatinib, a spleen tyrosine kinase inhibitor (SYK), to reduce the levels of mucin-1, a molecule associated with acute lung injury and acute respiratory distress syndrome (ARDS). People who have severe COVID-19 disease may develop ARDS.

How lockdown stopped the virus in Italy

Thu, 07/02/2020 - 09:07
Previous studies have shown that many severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cases were tied to asymptomatic carriers or those who do not manifest symptoms of the viral infection. Now, a new study reveals that in the first Italian town hit by the virus, as much as 40 percent of the population had no symptoms of the coronavirus disease (COVID-19).

Coronavirus immunity is higher than previously thought, study finds

Thu, 07/02/2020 - 08:44
Now, a team of researchers at the Karolinska Institutet and Karolinska University Hospital in Sweden has found that the number of people immune to COVID-10 may be higher than previously thought, and that antibody testing may no longer be the appropriate tool to trace it.

Thu, 07/02/2020 - 08:24
A team of scientists at the University of California San Francisco has found out how SARS-CoV-2, the virus that causes the coronavirus disease (COVID-19) invades proteins in the cells that serve as master regulators of key cellular processes.
