Study sheds new light on the link between oral bacteria and diseases

Researchers at Karolinska Institutet in Sweden have identified the bacteria most commonly found in severe oral infections. Few such studies have been done before, and the team now hopes that the study can provide deeper insight into the association between oral bacteria and other diseases. The study is published in Microbiology Spectrum.

Previous studies have demonstrated clear links between and , such as cancer, , diabetes and Alzheimer’s disease. However, there have been few identifying which occur in infected oral-and maxillofacial regions. Researchers at Karolinska Institutet have now analyzed samples collected between 2010 and 2020 at the Karolinska University Hospital in Sweden from patients with severe oral infections and produced a list of the most common bacteria.

This was a collaborative study that was performed by Professor Margaret Sällberg Chen and adjunct Professor Volkan Özenci’s research groups.

Study: MRI scans show widespread brain changes in children with ADHD

Nov. 23 (UPI) — Researchers said Wednesday they found changes in almost all the regions of the brain they investigated via MRI scan data of children with attention-deficit/hyperactivity disorder.

Children with ADHD had abnormal connectivity in the brain networks involved in memory processing and auditory processing, a thinning of the brain cortex, and significant white matter microstructural changes, especially in the frontal lobe of the brain.

The results of the new research on brain biomarkers of ADHD — based on analysis of data from MRI exams of 7,805 children — is scheduled to be presented Sunday at the annual meeting of the Radiological Society of North America.

Mapping the effects of pregnancy on resting state brain activity, white matter microstructure, neural metabolite concentrations and grey matter architecture

Animal studies have shown that pregnancy is associated with unique changes in the mammalian brain and behaviour, although pregnancy-associated changes in the human brain are less well studied. Here the authors show that pregnancy is associated with changes in resting state brain activity and brain anatomy which are most pronounced in the default mode network.

Phantom Neuro.
Phantom is a neurotechnology company, spun out of the lab at The Johns Hopkins University School of Medicine, that is enabling lifelike control of robotic orthopedic technologies, such as prosthetic limbs and exoskeletons. Phantom’s solution, the Phantom X, consists of low-risk implantable sensors, AI, and enabling software. By providing superior control of robotic orthopedic mechanisms, the Phantom X will drastically improve the lives of individuals with limb difference who have yet to see a tangible improvement in quality of life despite significant advancements in the field of robotics.

Personality similarity predicts synchronous neural responses in fMRI and EEG data

Successful communication and cooperation among different members of society depends, in part, on a consistent understanding of the physical and social world. What drives this alignment in perspectives? We present evidence from two neuroimaging studies using functional magnetic resonance imaging (fMRI; N = 66 with 2,145 dyadic comparisons) and electroencephalography (EEG; N = 225 with 25,200 dyadic comparisons) to show that: the extent to which people’s neural responses are synchronized when viewing naturalistic stimuli is related to their personality profiles, and that this effect is stronger than that of similarity in gender, ethnicity and political affiliation.

Highly ruminative individuals with depression exhibit abnormalities in the neural processing of gastric interoception

Major depressive disorder is associated with altered interoception — or the ability to sense the internal state of your body. Now, new brain imaging research provides evidence that depressed individuals tend to exhibit “faulty” neural processing of gastric interoception, particularly among those with high levels of rumination. The findings have been published in the Journal of Psychiatric Research.

“Repetitive negative thinking (RNT), usually referred to as ‘rumination’ in persons who suffer from depression, is a very significant clinical problem,” explained study author Salvador M. Guinjoan, a principal investigator at the Laureate Institute for Brain Research and associate professor at Oklahoma University Health Sciences Center at Tulsa.

“The reason is that when it is severe and persistent, RNT conditions higher chances of depression relapse and is associated with residual symptoms after treatment, is more common in persons who do not respond to treatment, and is even related to suicide. This particular communication refers to one among a series of projects in our lab attempting to understand rumination.”

The world’s largest Alzheimer’s study has made a gene discovery that could lead to treatments

The discovery could lead to potential future targeted therapies and treatments for this brain disorder.

Researchers have found two novel genes that increase an individual’s risk of developing Alzheimer’s disease (AD). This disorder is the leading cause of dementia and has an estimated heritability —genetic factor causing variation in the population, or an inherited trait— of 70%.

New Alzheimer’s Genes Discovered in World’s Largest Study

Summary: Researchers have identified two new genes, ATP8B4 and ABCA1, that are implicated in Alzheimer’s disease. The genes impact the brain’s immune system and cholesterol processing, leading to an increased risk of developing Alzheimer’s disease.
