Genetic testing helps predict disease recurrence
A DNA-based analysis of blood cells soon after a stem cell transplant can predict likelihood of disease recurrence in patients with myelodysplastic syndrome (MDS), a group of cancerous disorders characterized by dysfunctional blood cells. Such a practice could help doctors identify patients at high risk of disease recurrence early after a transplant and help guide treatment decisions.

Zika virus strips immune cells of their identity
Macrophages are immune cells that are supposed to protect the body from infection by viruses and bacteria. Yet Zika virus preferentially infects these cells. Researchers at University of California San Diego School of Medicine have now unraveled how the virus shuts down the genes that make macrophages function as immune cells.

Half of European clinical trials do not report results
Half of clinical trials on the EU register have not reported results, despite rules requiring results to be posted within 12 months of completion, finds a study published by The BMJ. Findings show compliance has been poor overall, but companies show higher rates of compliance than academics

Discovering cancer cell mutations with optimized technologies
Cancer cells often have mutations in their DNA that can give scientists clues about how the cancer started or which treatment may be most effective. Finding these mutations can be difficult, but a new method may offer more complete, comprehensive results. A team of researchers has developed a new framework that can combine three existing methods of finding these large mutations - or structural…

Growing cartilage – how does it work?
Anyone with arthritis can appreciate how useful it would be if scientists could grow cartilage in the lab. To this end, Keck School of Medicine of USC scientists in the USC Stem Cell laboratory of Denis Evseenko, MD, PhD, collaborated with colleagues at several institutions to provide new insights into how gene activity drives the development of cartilage. Their findings appear in Nature…

Zika virus proteins inhibit brain development
In healthy individuals, the Zika virus causes flu-like symptoms. If a pregnant woman becomes infected, the unborn child can suffer from severe brain abnormalities as a result of mechanisms that have not yet been explained. A study by the Technical University of Munich (TUM) and the Max Planck Institute of Biochemistry (MPI-B) shows that Zika virus proteins bind to cellular proteins that are…

Liver disease drug could help restore cells damaged by Alzheimer's
A drug which has been used to treat liver disease for decades could help to restore cells damaged by Alzheimer's, a new study from the University of Sheffield has found. The pioneering study discovered the drug ursodeoxycholic acid (UDCA) improves mitochondrial dysfunction – which is known to be a causative factor for both sporadic and familial Alzheimer's disease.

Link between obesity, the brain, and genetics
Clinicians should consider how the way we think can make us vulnerable to obesity, and how obesity is genetically intertwined with brain structure and mental performance, according to new research. The study, led by researchers at the Montreal Neurological Institute and Hospital (The Neuro), was an examination of MRI and cognitive test data from 1,200 individuals, supplied as part of the Human…

Researchers 3D print prototype for bionic eye
A team of researchers at the University of Minnesota have, for the first time, fully 3D printed an array of light receptors on a hemispherical surface. This discovery marks a significant step toward creating a “bionic eye” that could someday help blind people see or sighted people see better. The research is published in Advanced Materials, a peer-reviewed scientific journal covering…

Do our hearts beat digital or analog?
Scientists at the Virginia Tech Carilion Research Institute (VTCRI) have found evidence that may disrupt conventional understanding about how electrical activity travels in the heart — a discovery that potentially can lead to new insight into medical problems such as heart arrhythmia and sudden cardiac death.

The many causes of dilated cardiomyopathy
A major study has been launched to investigate the interaction between genes and lifestyle factors and dilated cardiomyopathy (DCM). Led by Professor Stuart Cook, at the National Heart and Lung Institute, this, the largest ever DCM study, will investigate why people develop DCM, with a focus on who is most at risk of sudden death or heart failure (HF). Six hospital trusts across England –…

ESC 2018: At the heart of research
When delegates from around 150 countries converge on Munich for ESC Congress 2018 they will no doubt reflect on what they themselves eat. Yes, nutrition is up for debate, questioning, for example, whether weight loss therapies can also prevent heart attacks and strokes. Results from the CAMELLIA-TIMI 61 trial of 12,000 overweight individuals with established cardiovascular disease or diabetes…

First steps towards a new, targeted lung cancer treatment
Scientists have identified a key molecular player in a subtype of lung cancer which could lead to a new way to tackle the disease, according to research published in Nature Communications. They found lung squamous cell carcinoma (LUSC) cells contained high amounts of a protein called BCL11A. The study showed that manipulating the gene responsible for the protein stopped the development of LUSC in…

Why getting rid of tighty-whities is good for your fertility
Researchers have discovered a good reason to not wear tight-fitting underwear – beyond the obvious aspect of fashion: According to new research led by Harvard T.H.

CMT: Unlikely ally against deadly neuropathy
Charcot-Marie-Tooth (CMT) disease is the most common hereditary neuropathy and affects more than two million people worldwide. In Germany, at least 30.000 people suffer from CMT which belongs to the class of rare disease. In a close collaboration, researchers at the Max-Planck-Institute for Experimental Medicine and the University Medical Center of Göttingen now hope to use lecithin, a harmless…

New research shows that for the vast majority of individuals, sodium consumption does not increase health risks except for those who eat more than five grams a day, the equivalent of 2.5 teaspoons of salt. Fewer than five per cent of individuals in developed countries exceed that level. The large, international study also shows that even for those individuals there is good news. However, the…

Pathway Ebola virus uses to enter cells pinpointed
The new outbreak of the deadly Ebola virus declared just last week in eastern Democratic Republic of Congo is believed to have claimed more than 30 victims so far, highlighting the continued urgency to find a way to stop the pathogen from killing the people it infects. A new study is shedding light on the role of specific proteins that trigger a mechanism allowing Ebola virus to enter cells to…

Why our brains fold the way they do
Everyone knows what our brains look like – but why is it folded up like that? Looking at other species reveals much less folding or even none at all. Scientists in Dresden, Germany, have now taken a closer look at the ridges and grooves of human brains. They discovered what causes our brains to fold – and what happens when the folding process goes wrong.

Drinking will put your brain at risk (but then again, abstinence might, too)
People who abstain from alcohol or consume more than 14 units a week during middle age (midlife) are at increased risk of developing dementia, finds a study in The BMJ today. However, the underlying mechanisms are likely to be different in the two groups. As people live longer, the number living with dementia is expected to triple by 2050. So understanding the impact of alcohol consumption on…

How cancer cells 'brainwash' their foes
It doesn’t often happen that army generals switch sides in the middle of a war, but when cancer is attacking, it may cause even a gene that acts as the body’s master defender to change allegiance.
