A new Finnish study, published in the journal Frontiers in Microbiology, finds that endurance exercises may change the composition of gut microbiota.
The researchers developed a 6-week program of bicycle training and enrolled 17 overweight women for this program. All women led a sedentary lifestyle before joining the study.
At the end of the program, the scientists noticed that the number of proteobacteria, gut bacteria that cause inflammation, decreased and the number of beneficial bacteria Akkermansia, linked to better metabolism, increased.
The corresponding author of the study Satu Pekkala, an Academy of Finland research fellow affiliated with the Faculty of Sport and Health Sciences of the University of Jyväskylä, explains: “These changes are beneficial for cardiometabolic health, because VLDL transports lipids from the liver to peripheral tissues, converts into ‘bad’ LDL [low-density lipoprotein] cholesterol in the circulation, and thus has detrimental cardiovascular effects.”
A new international study, led by researchers from the University of Cambridge in the United Kingdom, confirms evidence that dairy fats may decrease the risk of type 2 diabetes.
For the study, a team of the researchers analyzed the data received from 16 prospective cohorts that included 63,682 participants from 12 countries. Having analyzed the data, the researchers discovered that people who consumed more dairy products had the lower risk of type 2 diabetes.
The lead researcher Dr. Fumiaki Iamamura says: “We hope that our findings and existing evidence about dairy fat will help inform future dietary recommendations for the prevention of lifestyle-related diseases.”
A new study, conducted by scientists from the Karolinska Institute and Stockholm University, Sweden, suggests that atrial fibrillation is associated with the increased risk of developing dementia.
For the study, a team of researchers has analyzed the data of 2,685 participants whose average age was 73 years. The scientists interviewed the participants and conducted a medical examination at baseline. After that, the participants younger than 78 was followed for 6 years, and the participants older than 78 were examined every 3 years.
The researchers explain in their paper: “Assuming that there was a cause-and-effect relationship between using blood thinners and the reduced risk of dementia, we estimated that about 54 percent of the dementia cases would have been hypothetically prevented if all of the people with atrial fibrillation had been taking blood thinners.”
A new study, published in the Journal of Endocrinology, suggests that excessive consumption of vitamin A may lead to the higher risk of weak and fracture bones.
In the study, a team of researchers from Sahlgrenska Academy at the University of Gothenburg investigated the influence of vitamin A doses equivalent to doses consumed by people taking supplements during long-time periods.
Dr Ulf Lerner, the lead researcher, comments: “Previous studies in rodents have shown that vitamin A decreases bone thickness but these studies were performed with very high doses of vitamin A, over a short period of time. In our study, we have shown that much lower concentrations of vitamin A, a range more relevant for humans, still decreases rodent bone thickness and strength.”
Researchers from Florida Atlantic University, US, have found a new pathway in the brain associated with the behavioral symptoms of autism spectrum disorder (ASD) and a drug to quell these symptoms.
The drug treated the behavioral disruptions in mice with autism. Scientists believe that it may have the same effect for adults with the condition.
Firstly, 25 years ago, it was discovered that a genetic mutation interferes with the serotonin regulation in people with autism. Serotonin is a key neurotransmitter to the feeling of happiness and plays important role in social functioning.
Then, a particular enzyme was found that had a drastic effect on the reabsorption of serotonin. After that, an experimental compound called MW150 was developed and tested on mice.
