blog postsDivision of labor within regenerating liver maintains metabolism, mouse study findsMar 1, 2021 2:00 pm237 views The liver has a rare superpower among body organs – the ability to regenerate, even if 70% of its mass is removed. It also keeps up its metabolic and toxin-removing work during the process of regeneration, thanks to a subset of cells that expand their workload while the rest focus on multiplication, a new study in mice found.Virtual reality program lessens physical side effects of hemodialysisFeb 24, 2021 12:00 pm435 views A virtual reality program on mindfulness/meditation helped hemodialysis patients alleviate the physical side effects and tedium of their treatments in a new research project led by social work professor Rosalba Hernandez.Carle Illinois College of Medicine granted provisional accreditationFeb 22, 2021 9:00 am3040 views The Carle Illinois College of Medicine, a partnership between the University of Illinois Urbana-Champaign and Carle Health, has been granted provisional accreditation by the Liaison Committee on Medical Education.

Published in the Journal of Clinical Medicine, the study suggests that the link between cardiorespiratory fitness and cognitive health is evident even earlier in life than previously appreciated.3D microscopy clarifies understanding of body's immune response to obesityFeb 17, 2021 1:00 pm992 views Researchers who focus on fat know that some adipose tissue is more prone to inflammation-related comorbidities than others, but the reasons why are not well understood. Thanks to a new analytical technique, scientists are getting a clearer view of the microenvironments found within adipose tissue associated with obesity. This advance may illuminate why some adipose tissues are more prone to inflammation – leading to diseases like type 2 diabetes, cancer and cardiovascular disorders – and help direct future drug therapies to treat obesity.Study links prolonged sedentary time to distractibility in adults with obesity or overweightFeb 17, 2021 8:15 am441 views Scientists used accelerometers to track daily activity levels for a week in 89 adults with obesity or overweight and, in a series of tests, measured their ability to multitask and maintain their attention despite distractions. The study revealed that individuals who spent more sedentary time in bouts lasting 20 minutes or more were less able to overcome distractions.Patient education program with mental health component reduces cardiovascular disease risksFeb 11, 2021 9:45 am472 views Participants in a health education program that included both mental and physical health information significantly reduced their risk factors for cardiovascular disease and maintained most of those improvements six months later.Lipid epoxides target pain, inflammatory pathways in neuronsFeb 10, 2021 4:00 am1217 views A process known as epoxidation converts two naturally occurring lipids into potent agents that target multiple cannabinoid receptors in neurons, interrupting pathways that promote pain and inflammation, researchers report in a new study.

The study found that new experiences of sexual, emotional and physical abuse at the hands of a romantic partner during this period are associated with increasing symptoms of trauma such as anxiety, depression, self-harm and sleep disorders. It also found that having experienced abuse in childhood appears to worsen the impact of current abuse on those symptoms.Beliefs about cannabis influence older adults' choice of treatments for chronic painJun 17, 2020 7:30 am1546 views Pain levels and quality-of-life issues have little influence on older adults’ decisions to treat chronic pain and other long-term diseases or conditions with cannabis or opioids, a new U. of I. study found.Environmental contaminants alter gut microbiome, healthMay 21, 2020 8:00 am1448 views Scientists review the research linking dozens of environmental chemicals to changes in the gut microbiome and associated health challenges.
