Gut microbiome linked to behavioral problems in children

Children with behavioral problems may have different compositions in their gut microbiome, with parents playing a major role in how pronounced the differences were, other than the food they provide, a new study suggests.

New analysis method shows how the brain regulates its signals using glutamate

Researchers at Chalmers University of Technology and Gothenburg University in Sweden have achieved something long thought almost impossible - counting the molecules of the neurotransmitter glutamate released when a signal is transferred between two brain cells. With a new analysis method, they showed that the brain regulates its signals using glutamate in more ways than previously realised.

Burnout linked to higher risk for abnormal heart rhythm

A new study published in January 2020 in the European Journal of Preventive Cardiology shows that burnout could really cause your heart to fail as a result of an abnormal heart rhythm called atrial fibrillation (AF).

Researchers study the effects of antidepressants to identify the least harmful drugs

About one in ten women in Québec will suffer from depression during pregnancy. Without treatment, the illness carries risks for both mother and child.

No clear evidence to determine if psychotherapy or medications are more effective for treating PTSD

A new study that sought to find out whether serotonin reuptake inhibitors or trauma-focused psychotherapy is more effective in treating posttraumatic stress disorder (PTSD) concluded there is insufficient evidence at present to make that determination.

Scientists evaluate mouse models used for developing new treatments for Huntington's disease

Huntington's disease (HD) is an incurable and fatal hereditary disease. Developing disease-modifying drugs to treat patients with HD depends on studying them in animal models. Scientists evaluated the mouse models used for developing new treatments for mood disorders in HD and recommended which of these models are most relevant to their studies.

Blood pressure drug could be beneficial in treating alcohol use disorders

A drug used to treat high blood pressure may alleviate anxiety induced by long-term heavy alcohol use, and also halt the damage such drinking can cause to the brain's ability to grow new cells, research at the Queensland University of Technology shows.

New computational method can help predict and design allosteric functions in proteins

Called the "second secret of life", allostery is one of the most fundamental processes of biology and has been a central focus among scientists across the life sciences spectrum, from fundamental biology to drug development.

New findings could help clinicians to improve care for pregnant women and new mums with depression

Professor Sue Jordan from the University's College of Human and Health Science, who led the study, says the findings could be used to help clinicians improve care for women during pregnancy and after they have given birth.

New technique enables the study of transporter proteins at a single-molecule level

Like a boat helping passengers cross a river, transporters move substances across cell membranes. This process is fundamental to the healthy functioning of cells in life forms from bacteria to humans.

Depression in middle and older adulthood associated with nutrition

Your diet can put you at risk of depression, according to a new study. The study also found that the likelihood of depression is higher among middle-aged and older women who were immigrants to Canada when compared to Canadian-born women.

Study supports physical activity as a preventive measure for depression

A new study has found that physical activity may have a preventative effect against depression. Physical activity has long been linked with better mental health due to its ability to reduce the stress hormone cortisol and increase the feel-good hormone serotonin. However, there has been limited empirical evidence to support physical activity as a preventive measure for depression, making these findings very important.

Brain function changes could help diagnose and manage depression

Ever heard of the lateral habenula? Very few, outside of neuroscience, probably have. Yet a new study, published in the journal Neuron, shows that characteristic changes in the way this area of the brain fires can result in a total loss of will to do anything – which is characteristic of one form of depression.
