Diseases related to tobacco smoking have been shown to kill approximately half of long-term smokers when compared to average mortality rates faced by non-smokers. Giving up smoking has huge benefits … Continue Reading Brain circuit that supports smoking cessation identified.
It is known that brain structure is under strong genetic control, and while researchers understand that genes strongly underpin brain development, it is still unclear which specific genes are implicated … Continue Reading Neurogenetic twin study provides a new model of the human brain.
Magnetic resonance imaging (MRI) has been used to evaluate obstetrical, placental, and fetal abnormalities in pregnant patients for more than 30 years. MRI is recognized as a beneficial diagnostic tool … Continue Reading Study shows that MRIs in first trimester of pregnancy not associated with increased risk to fetus.
With the growing prevalence of childhood obesity, the incidence of type 2 diabetes in children and adolescents is increasing at an alarming rate. Type 2 diabetes may become the most … Continue Reading Neuroimaging shows gray matter changes in brains of teenagers with type 2 diabetes.
Body mass index (BMI) is an important risk factor for breast cancer development and invasiveness. After menopause, women have an increased risk of developing breast cancer with increased BMI, while … Continue Reading New MRI technique links saturated fats to breast cancer in postmenopausal women.
Performance of cognitive tasks requires reallocation of resources within and among cortical networks. Understanding the molecular mechanisms that govern such network dynamics is a longstanding goal of cognitive neuroscience. A … Continue Reading Neuroimaging maps interaction between neural networks during working memory.
The blood-brain barrier (BBB), a collection of cells and subcellular structures in the cerebrovascular wall that separates the circulating blood from the brain, is essential to keep brain tissue in … Continue Reading Leakages identified in the blood-brain barrier of patients with early Alzheimer’s disease.
Mesenchymal stem cells (MSCs) are among the major stem cells used for cell therapy and regenerative medicine. In-vivo cell-tracking by magnetic resonance imaging (MRI) is crucial for regenerative medicine, allowing … Continue Reading Biomimetic method produces large numbers of MRI-trackable mesenchymal stem cells.
With more than 25% of high school seniors reporting recent use and 6.5% of 12th graders being daily users, marijuana (MJ) is the most frequently used illicit substance among adolescents. … Continue Reading Neuroimaging shows that young starting age of marijuana causes arrested neurodevelopment.
Homeostasis is the property of a system in which variables are regulated so that internal conditions remain stable and relatively constant. The human body manages a multitude of highly complex … Continue Reading Neuroimaging identifies previously unknown circuitry in brain homeostasis.
Alzheimer’s disease is a progressive illness that is the leading cause of dementia and the sixth leading cause of death in the United States. There is no cure for the … Continue Reading Neuroimaging links two Alzheimer’s risk genes to brain atrophy, promising blood markers.
Internet gaming disorder (IGD) is defined as a failure to control one’s impulses to excessively use online gaming. IGD results in serious negative outcomes, such as decreased physical and mental … Continue Reading Neuroimaging identifies brain differences in compulsive video game players.
As a part of the human immune system, white blood cells create a number of enzymes that help fight disease. Sometimes, these enzymes can malfunction, causing damage to the body … Continue Reading Study sheds light on cancer-spreading enzymes produced by the immune-system.
Cerebral blood flow is rigorously regulated by various mechanisms to safeguard the match between cerebral metabolic demand and supply. The question of how a change in heart health affects cerebral … Continue Reading Large-scale human study identifies link between early-stage heart and brain disease.
People with diabetes are more likely to have high blood pressure and high cholesterol and are much more likely to develop cholesterol blockages in their arteries. A person with diabetes … Continue Reading 3-D MRI can show stroke risk in diabetic patients even before narrowing of arteries.
