As neuroscience strives for generalizability and fairness, it is important to understand the diversity of the human brain across populations. To clarify how ethnic/race-related differences in the brain’s functional connectome arise without falling into biological essentialism, the team of Professors Tianyi Yan and Guoyuan Yang from Beijing Institute of Technology recently published a study. the study. Using multimodal behavioral data from the Human Connectome Project (HCP), they built a multilayered framework to systematically uncover the driving mechanisms behind this population diversity. Anatomy serves as a “baton” for function. Researchers found that ethnicity/race-related differences in brain functional topography and functional connectivity…
Children and adolescents with high BMI show distinct differences in brain activity and the way different brain regions communicate with each other. These neurological patterns indicate a decline in the brain’s natural inhibitory systems, which can make it difficult to change deeply ingrained habits. The results of this study were recently published in the journal Clinical Neurophysiology. The human brain continues to develop and be significantly rewired throughout childhood and adolescence. The frontal cortex, the brain region responsible for impulse control and complex decision-making, is one of the last regions to fully mature. During this long period of development, the…
Recent research has shown evidence that TikTok’s recommendation system tends to expose users to more conservative and anti-Democratic political content than liberal content. This ideological imbalance occurs regardless of users’ initial political interests, suggesting that automation plays an important role in modern information access. The study was published in a scientific journal nature. Researchers at New York University Abu Dhabi’s Institute for AI and Society conducted a new study exploring how automated internet systems are shaping the political news people see. Experts debate whether the internet’s polarization is caused by people seeking their preferred viewpoints, or by computer algorithms pushing…
A new study led by a team at the University of Ottawa takes a major step forward in understanding how heart attacks can dramatically alter brain function and cause neurological effects ranging from depression and anxiety to various types of cognitive decline. This “heart-brain axis” concept suggests that neurological conditions after a heart attack may be caused in part by molecular changes caused by damage to the heart. Although many factors and signaling pathways are involved in the heart-brain interaction, this newly published study suggests that toxic byproducts produced within the body play a major role in the brain after…
For many people living with HIV, today’s treatments can suppress the virus and dramatically improve their health. But even when HIV is controlled, the disease’s damage to the gut can persist and cause chronic inflammation that can lead to serious health problems. New research from Tulane University shows that JCI Insights It helps explain why. Researchers have found that long-term antiretroviral treatment does not fully restore important immune functions that protect and repair the intestinal lining. The study also found early evidence that dietary compounds found in mustard family vegetables, such as broccoli and cabbage, may help support immune activity…
Fine particulate matter from wildfires is associated with an increase in mental health emergencies in children and teens, according to a recent multi-country analysis. Researchers observed an increase in patients presenting to emergency departments with symptoms such as anxiety, depression, and schizophrenia after days of exposure to wildfire smoke. These results are detailed in a paper published in Nature Mental Health. Particulate matter consists of tiny water droplets and ash debris suspended in the air. These particles are incredibly small, about one-thirtieth the width of a human hair. Because of their small size, they can be inhaled deep into the…
Research led by researchers in National Heart and Vascular Research Center (CNIC) has identified a mitochondrial “checkpoint” that allows dendritic cells to efficiently activate T lymphocytes against viruses and tumors. Dendritic cells are immune cells that detect threats and activate the body’s defenses, acting as “sentries” that tell T lymphocytes what to attack. This research scientific immunologyshow that restoring the internal chemical imbalance caused by defects in mitochondrial function in dendritic cells restores the ability of immune cells to protect the body from infection. This discovery could open new avenues for improving cancer immunotherapy. This study revealed that the ability…
A new oral antiviral drug candidate has been developed to treat diseases caused by orthoparamyxoviruses, such as measles and croup syndrome, according to research published by researchers at Georgia State University’s Center for Translational Antiviral Research. Research published in journals scientific progress We identified GHP-88310, a clinical candidate for improved orthoparamyxovirus disease management that is urgently needed in rodent and non-rodent infected animal models. Orthoparamyxoviruses, such as human parainfluenza virus, measles virus, and emerging henipavirus, pose a significant threat to human health. We developed GHP-88310 to treat orthoparamyxovirus infections. GHP-88310 is the most promising inhibitor of this virus family…
Background and purpose The optimal management strategy for adults with chronic immune tolerance (IT) hepatitis B infection remains to be defined. This study aimed to investigate the efficacy and predictive factors of pegylated interferon (Peg-IFN)-based therapeutic strategies in IT patients with chronic HBV infection. method In this pilot, open-label, prospective study, 286 patients aged 18 to 60 years with IT characteristics were enrolled and assigned to one of three groups. The combination group received Peg-IFN for 48 to 96 weeks, and tenofovir disoproxil fumarate (TDF) was started at week 12 and continued through week 96 (n = 103). The monotherapy…
More than 135 million adults in the United States have or are at increased risk of developing type 2 diabetes (T2D), increasing the need for reliable nutrition guidance backed by scientific research. A newly published randomized controlled trial (RCT) found that eating 6 to 7 ounces of beef daily had no negative effects on blood sugar regulation, insulin function, inflammation, or other markers of cardiometabolic health in adults with prediabetes. The study was published in the same journal as “The effects of a diet containing beef compared with poultry on pancreatic beta-cell function and other cardiometabolic health indicators in prediabetic…
