A lack of self control during adolescence is not uniquely human

Impulsiveness in adolescence isn’t just a phase, it’s biology. And despite all the social factors that define our teen years, the human brain and the brains of other primates go through very similar changes, particularly in the areas that affect self-control.

New, healthier 'butter' spread almost entirely water

Food scientists have created a new low-calorie ‘butter’ spread that consists mostly of water. A tablespoon of this low-calorie spread has 2.8 grams of fat and 25.2 calories. Butter, on the other hand, which is 84% fat and about 16% water, has about 11 grams of fat and nearly 100 calories. Source: Science Daily, https://www.sciencedaily.com

Toolkit could improve detection and management of iron deficiency in pregnancy

Iron deficiency in pregnancy is a common problem that often goes unrecognized and untreated due to a lack of knowledge of its implications and competing clinical priorities. To enhance screening and management of iron deficiency in pregnancy, a research team has developed a quality improvement toolkit, called IRON MOM. The implementation of IRON MOM resulted … pročitajte više

British food crowned the healthiest in major global survey

Is pollution linked to psychiatric disorders?

Researchers are increasingly studying the effects of environmental insults on psychiatric and neurological conditions, motivated by emerging evidence from environmental events like the record-breaking smog that choked New Delhi two years ago. The results suggests a possible link between exposure to environmental pollution and an increase in the prevalence of psychiatric disorders. Source: Science Daily, … pročitajte više

Discharge incentives in emergency rooms could lead to higher patient readmission rates

In an effort to address emergency department overcrowding, pay-for-performance (P4P) incentive programs have been implemented in various regions around the world, including hospitals in Metro Vancouver. But a new study shows that while such programs can reduce barriers to access for admitted patients, they can also lead to patient discharges associated with return visits and … pročitajte više

New hydrogels show promise in treating bone defects

Bioengineers and dentists have developed a new hydrogel that is more porous and effective in promoting tissue repair and regeneration. Once injected in a mouse model, the new hydrogel is shown to induce migration of naturally occurring stem cells to better promote bone healing. Current experimental applications using hydrogels and stem cells introduced into the … pročitajte više

Examining the link between caste and under-five mortality in India

In India, children that belong to disadvantaged castes face a much higher likelihood of not living past their fifth birthday than their counterparts in non-deprived castes. Researchers examined the association between castes and under-five mortality in an effort to help reduce the burden of under-five deaths in the country.

Multi-tasking protein at the root of neuropathic pain

Neuropathic pain is a chronic condition resulting from nerve injury and is characterized by increased pain sensitivity. Although known to be associated with overly excitable neurons in the spinal cord, the mechanisms leading to chronic pain are poorly understood. Researchers have now shown that expression of a protein called FLRT3 in the spinal dorsal root … pročitajte više

Lab-on-a-chip drives search for new drugs to prevent blood clots

The effectiveness of current anti-clotting medication can be limited due to the risk of complications. This is driving a need for alternatives that can both prevent the formation of blood clots and reduce the risk of excessive and life-threatening bleeding. A new biocompatible lab-on-a-chip could help accelerate the discovery and development of new anti-clotting therapies, … pročitajte više

Mini kidneys grown from stem cells give new insights into kidney disease and therapies

Medical researchers have grown ‘miniature kidneys’ in the laboratory that could be used to better understand how kidney diseases develop in individual patients. These kidney organoids were grown outside the body from skin cells derived from a single patient who has polycystic kidney disease. This method has paved the way for tailoring treatment plans specific … pročitajte više

Pluripotency: 'Butterfly effect' discovered

Pluripotent cells can give rise to all cells of the body, a power that researchers are eager to control because it opens the door to regenerative medicine and organ culture for transplants. But pluripotency is still a black box for science, controlled by unknown genetic and epigenetic signals. Researchers have now uncovered one of those … pročitajte više

Simple computational models can help predict post-traumatic osteoarthritis

Researchers have developed a method to predict post-traumatic osteoarthritis in patients with ligament ruptures using a simplified computational model. The researchers also verified the model predictions against measured structural and compositional changes in the knee joint between follow-up times.

City parks lift mood as much as Christmas

New research shows that visitors to urban parks use happier words and express less negativity on Twitter than before their visit — and that their elevated mood lasts for up to four hours. The effect is so strong that it’s equivalent to the mood spike on Christmas, the happiest day each year on Twitter. With … pročitajte više

E. coli's secret weapon in launching infections

Most types of Escherichia coli are harmless, but the ones that aren’t can cause severe life-threatening diarrhea. These problematic bacteria launch infections by inducing intestinal cells to form tiny structures, called pedestals, that anchor the pathogens in place and help the colonies grow.

Brain takes a beating as arteries age

Researchers have presented a model that explains why memory deteriorates as the body ages. With age, the brain receives an increased load from the heart’s beating as the body’s large arteries stiffen over the years, causing damage to the smallest blood vessels in the brain.

Possible genetic link between children's language and mental health

A new study has examined genetic variants in six genes that are thought to contribute to language development in children. They found that nearly half of the genetic variants which contribute to children’s language difficulties were also associated with poor mental health.

Risk of psychotic disorders has disease-specific brain effects

Brain abnormalities in people at familial risk of schizophrenia and bipolar disorder emerge in unique patterns, despite the symptom and genetic overlap of the disorders, according to a new study. Similarities between schizophrenia and bipolar disorder have led to the diagnoses being increasingly combined in studies of psychosis, but the findings highlight that risk for … pročitajte više
