Brain protein promotes maintenance of chronic pain Posted: 11 Oct 2019 01:53 PM PDT Study results illuminate the potential of novel approach for the treatment of chronic pain. |
Coffee bean extracts alleviate inflammation, insulin resistance in mouse cells Posted: 11 Oct 2019 11:46 AM PDT Food science and human nutrition researchers are interested in the potential of inflammation-fighting compounds found in the silverskin and husk of coffee beans, not only for their benefits in alleviating chronic disease, but also in adding value to would-be 'waste' products from the coffee processing industry. |
Opioid Rx dosages drop with state law changes Posted: 11 Oct 2019 11:46 AM PDT The total amount of opioids dispensed per new opioid prescription decreased by 22% in Penn Medicine outpatient practices in New Jersey after the state passed a law limiting prescriptions to a five-day supply for new opioid prescriptions. Penn Medicine implemented an electronic health record (EMR) alert, or 'nudge,' to notify clinicians if that limit had been reached. |
Sox9 reshapes the biliary tree in Alagille syndrome Posted: 11 Oct 2019 10:19 AM PDT Mose model shows that SOX9 gene influences the severity Alagille syndrome. |
Slower walkers have older brains and bodies at 45 Posted: 11 Oct 2019 08:22 AM PDT The walking speed of 45-year-olds can be used as a marker of their aging brains and bodies. The evidence was there in neurocognitive testing these individuals took at age 3 to indicate who would become the slower walkers. At 45, slower walkers have 'accelerated aging' on a 19-measure scale devised by researchers, and their lungs, teeth and immune systems tended to be in worse shape than the people who walked faster. |
New test diagnoses Lyme disease within 15 minutes Posted: 11 Oct 2019 08:22 AM PDT Current testing for Lyme disease, called the standard 2-tiered approach or the STT, involves running two complex assays (ELISA and western blot) to detect antibodies against the bacterium, and requires experienced personnel in a lab, and a few hours to carry out and interpret. Biomedical engineers have developed a rapid microfluidic test that can detect Lyme disease with similar performance as the STT in a much shorter time -- 15 minutes. |
Under time pressure, people tell us what we want to hear Posted: 11 Oct 2019 08:22 AM PDT When asked to answer questions quickly and impulsively, people tend to respond with a socially desirable answer rather than an honest one, a set of experiments shows. |
Expert second opinion improves reliability of melanoma diagnoses Posted: 11 Oct 2019 08:22 AM PDT A new study has found that obtaining a second opinion from pathologists who are board certified or have fellowship training in dermatopathology can help improve the accuracy and reliability of diagnosing melanoma. |
Overweight before age 40 increases the cancer risk Posted: 11 Oct 2019 08:22 AM PDT The risk of cancer increases considerably if you gain weight before the age of 40. |
Habitual tea drinking modulates brain efficiency: Evidence from brain connectivity evaluation Posted: 11 Oct 2019 08:22 AM PDT The researchers recruited healthy older participants to two groups according to their history of tea drinking frequency and investigated both functional and structural networks to reveal the role of tea drinking on brain organization. |
'Cross-transfer' benefits of special exercise technique questioned Posted: 11 Oct 2019 08:22 AM PDT Researchers question the effectiveness of a patented exercise system for relieving lower back pain. |
Population aging to create pockets of climate vulnerability in the US Posted: 11 Oct 2019 08:22 AM PDT Population aging projections across the US show a divide between cities and rural areas, which could lead to pockets of vulnerability to climate change. |
Overcoming the blood-brain-barrier: Delivering therapeutics to the brain Posted: 11 Oct 2019 06:59 AM PDT For the first time, scientists have identified a simple way that can effectively transport medication into the brain - which could lead to improved treatments for neurological and neurodegenerative diseases. |
Illumination of abnormal neuronal activities caused by myelin impairment Posted: 11 Oct 2019 06:59 AM PDT The neural circuit basis for motor learning tasks when myelination is impaired has been illuminated for the first time. Researchers also succeeded in compensating for the impaired motor learning process by pairing appropriate actions with brain photo-simulation to promote synchronization of neuronal activities. This could contribute to future treatments for neurological and psychiatric diseases in which white matter function is impaired. |
Powerful new genomics method can be used to reveal the causes of rare genetic diseases Posted: 11 Oct 2019 06:59 AM PDT The technique makes use of the fact that people inherit two copies or ''alleles'' of virtually every gene, one from the mother and one from the father. The new method compares activity levels of maternal and paternal alleles across the genome and detects when the activity of an allele lies far enough outside the normal range to be a plausible cause of disease. |
Rare sleep disorder common among veterans with PTSD Posted: 11 Oct 2019 06:59 AM PDT Military veterans with post-traumatic stress disorder or concussion suffer from a thrashing form of sleep behavior at a rate that is far higher than the general population, according to a new study. Researchers next want to probe whether the sleep disorder might provide an early signal of the development of neurodegenerative conditions such as Parkinson's disease. |
Chronobiology: Sleep and synaptic rhythms Posted: 11 Oct 2019 06:59 AM PDT Chronobiologists show how critical the sleep-wake cycle is for protein and phosphorylation dynamics in synapses to ultimately regulate its activity. |
Type 2 diabetes and obesity could be treated by new, less invasive procedure Posted: 11 Oct 2019 06:59 AM PDT New research has found that a newly tested medical device, called Sleeveballoon, mimics the effects of traditional bariatric surgery in rodents and produces impressive results on body weight, fatty liver and diabetes control. |
New genetic link found for some forms of SIDS Posted: 11 Oct 2019 04:47 AM PDT Some forms of sudden infant death syndrome stem from a genetic mutation that keeps infants from processing lipids in milk, a new study has discovered. The build-up of unprocessed fatty material disrupts heart functions. While no treatments are yet available, the finding could help in genetic screening. Drugs are also being tested to see if they can help. |
A reliable clock for your microbiome Posted: 11 Oct 2019 04:47 AM PDT The microbiome is a treasure trove of information about human health and disease, but getting it to reveal its secrets is challenging. A new genetic 'repressilator' circuit acts like a clock that tracks how bacterial growth changes over time with single-cell precision. This tool allows scientists to noninvasively study the dynamics of the microbiome, and also unlocks the potential for complex, synthetic-biology-based diagnostics and therapeutics for the human gut. |
Targeting immune cells may be potential therapy for Alzheimer's Posted: 11 Oct 2019 04:47 AM PDT A study has found that microglia drive neurodegeneration in diseases, including Alzheimer's disease, that are linked to tau protein. Targeting microglia may help treat such diseases. |
Jumping genes can cause rare developmental disorders in children Posted: 11 Oct 2019 04:47 AM PDT The largest study of its kind into childhood developmental disorders has discovered that jumping genes cause genetic changes in some patients with undiagnosed neurodevelopmental diseases. The research enabled genetic diagnoses for three children with previously undiagnosed rare developmental diseases, enrolled in the Deciphering Developmental Disorders project. Reported in Nature Communications, these diagnoses will help the families access support and understand the disease risks for any future children. |
Deciphering the early stages of Parkinson's disease is a matter of time Posted: 11 Oct 2019 04:47 AM PDT Researchers haveidentified for the first time the initial steps of alpha-synuclein protein aggregates related to early onsets of hereditary Parkinson cases. The results may help the understanding of the early stages of the disease and how it develops over time. |
