Measuring iron in the brain can point to dementia

According to the first author of the study George Thomas, “It’s really promising to see measures like this, which can potentially track the varying progression of Parkinson’s disease, as it could help clinicians devise better treatment plans for people based on how their condition manifests.”

The co-author of the study, Dr. Julio Acosta-Cabronero from Tenoke Ltd. and the Wellcome Centre for Human Neuroimaging, UCL, also comments on the findings:

Treatment of Neuroterrorism

Bioterrorism is defined as the intentional use of biological, chemical, nuclear, or radiological agents to cause disease, death, or environmental damage. Early recognition of a bioterrorist attack is of utmost importance to minimize casualties and initiate appropriate therapy. The range of agents that could potentially be used as weapons is wide, however, only a few of these agents have all the characteristics making them ideal for that purpose. Many of the chemical and biological weapons can cause neurological symptoms and damage the nervous system in varying degrees. Therefore, preparedness among neurologists is important. The main challenge is to be cognizant of the clinical syndromes and to be able to differentiate diseases caused by bioterrorism from naturally occurring disorders. This review provides an overview of the biological and chemical warfare agents, with a focus on neurological manifestation and an approach to treatment from a perspective of neurological critical care.

Scientists Find a Way to Create Needle-Free Vaccines That Dissolve in Your Mouth

The race is on to identify an effective vaccine for the COVID-19 virus. Once discovered, the next challenge will be manufacturing and distributing it around the world.

My research group has developed a novel method to stabilize live viruses and other biological medicines in a rapidly dissolving film that does not require refrigeration and can be given by mouth.

Since the ingredients to make the film are inexpensive and the process is relatively simple, it could make vaccine campaigns much more affordable. Large quantities could be shipped and distributed easily given its flat, space saving shape.

Coronavirus expert: ‘War is an appropriate analogy’

AI and Machine Learning: Streamlining and Focusing Clinical Trial Recruitment

Artificial intelligence (AI) and machine learning are increasingly becoming a part of drug discovery and development beginning with identifying new compounds to structuring and designing clinical trials and targeting clinical trial populations.

A recent example came out of Linköping University in Sweden. The investigators utilized an artificial neural network to create maps of biological networks based on how different genes or proteins interact with each other. They leveraged a large database with information about the expression patterns of 20,000 genes in a large group of people. The AI was then taught to find patterns of gene expression.

And in mid-February, a drug developed using AI began testing in human clinical trials. The molecule, DSP-1181, is currently in Phase I clinical trials for obsessive-compulsive disorder. The compound is a long-acting potent serotonin 5-HT1A receptor agonist developed using AI that was part of a collaboration between Japan’s Sumitomo Dainippon Pharma and the UK’s Escientia. The AI developed the compound in about 12 months, compared to a more typical five-year process.

Genome Sequencing for Healthy People: Is it Time?

Would you want to know if you’re at risk of Alzheimer’s disease, for example?


The integration of sequencing into health care doesn’t fit very well in the model of how medicine is practiced today, but is well aligned with the future vision of health care that so many of us have — a vision that focuses upon prediction and prevention.

We imagine that personal genome sequencing could play a central role in bringing about a more personalized and participatory form of medicine — including a health care system where patients have more knowledge of their own risks and diagnoses and are empowered to act upon that information.

With that in mind, more of us are asking this question: Rather than focusing only on people with a suspected or diagnosed genetic disease, why not also use genome sequencing to help seemingly healthy people screen for all sorts of conditions, even diseases for which they have no known family history?
