Researchers discover new insights about tau proteins in people living with ALS

Added: 15.11.2021 17:35 | 352 views | 0 comments

Investigators found elevated levels of tau and a phosphorylated form of the tau protein in brain tissue from deceased people who had amyotrophic lateral sclerosis (ALS) and carried a mutation in the C9orf72 gene. The team also identified new genetic mutations in the tau gene that may exacerbate ALS onset or progression. Tau in the cerebrospinal fluid may be a viable biomarker for ALS because levels correlate with disease progression.

Researchers train computers to predict the next designer drugs

Added: 15.11.2021 17:35 | 280 views | 0 comments

Researchers have trained computers to predict the next designer drugs before they are even on the market, technology that could save lives. Identifying these so-called 'legal highs' within seized pills or powders can take months, during which time thousands of people may have already used a new designer drug. But new research is already helping law enforcement agencies around the world to cut identification time down from months to days, crucial in the race to identify and regulate new versions of dangerous psychoactive drugs.

COVID patients on SSRI antidepressants are less likely to die, study finds

Added: 15.11.2021 17:35 | 286 views | 0 comments

A large analysis of health records from 87 health care centers across the United States found that people taking a class of antidepressants called selective serotonin reuptake inhibitors (SSRIs), particularly fluoxetine, were significantly less likely to die of COVID-19 than a matched control group.

Common blood pressure drug does not slow down the progression of more advanced Alzheimer’s, study finds

Added: 15.11.2021 17:35 | 565 views | 0 comments

New research has shown the drug losartan, normally used to treat high blood pressure (hypertension), is not effective in slowing down the progression of Alzheimer's disease (AD) in people with mild-to-moderate disease after 12 months of treatment. However, the drug could still be of benefit if prescribed for longer and if given to people with very early disease.

A key brain region responds to faces similarly in infants and adults

Added: 15.11.2021 17:35 | 273 views | 0 comments

In a functional magnetic resonance imaging study of babies ranging in age from two to nine months, researchers have found regions of the infant visual cortex that show strong preferences for either faces, bodies, or scenes, just as they do in adults.

Gut microbiota differences seen in people with autism may be due to dietary preferences

Added: 13.11.2021 20:08 | 272 views | 0 comments

Research suggested that autism spectrum disorder (ASD) may be at least partly caused by differences in the composition of the gut microbiota, based on the observation that certain types of microbes are more common in people with autism. But a new study suggests that the link may actually work the other way around: the diversity in species found in the guts of children with autism may be due to their restricted dietary preferences associated with autism, rather than the cause of their symptoms.

The outcome predictive models were developed in part using data from a large multi-center study. The findings provide strong evidence that the current trial-and-error approach used in clinical practice for the selection of the right antidepressant can be replaced with this new precision medicine approach.

In an unexpected discovery, researchers have identified what appears to be a significant vascular defect in patients with moderately severe Parkinson's disease. The finding could help explain an earlier outcome of the same study, in which the drug nilotinib was able to halt motor and non-motor (cognition and quality of life) decline in the long term.

Team engineers new way to get medication past blood-brain barrier

Added: 12.11.2021 17:15 | 294 views | 0 comments

A team of researchers has developed a new technique to open the blood-brain barrier temporarily to deliver medication to the brain. Getting medication past the brain's unique and protective blood vessels, known as the blood-brain barrier, is one of the biggest challenges in treating brain and central nervous system diseases, according to researchers. The technique uses light and nanoparticles to pry open temporarily these barriers -- called tight junctions -- to allow medication to reach its target.
