Dopamine, a neurotransmitter in our brains, not only regulates our emotions but also serves as a biomarker for the screening of certain cancers and other neurological conditions. https://medicalxpress.com/news/2024-09-rapid-dopamine.html Thu, 05 Sep 2024 17:03:04 EDT news644774581 Metabolic dysfunction-associated steatohepatitis (MASH) is one of the most common chronic liver diseases, primarily caused by metabolic disorders and systemic inflammatory responses. Although the incidence of MASH is gradually increasing, there is a lack of effective drugs and methods for its treatment, thus limiting therapeutic options for MASH. https://medicalxpress.com/news/2024-07-phytic-acid-based-nanomedicine-metabolic.html Tue, 16 Jul 2024 15:47:17 EDT news640363634 Targeting a non-encoding stretch of RNA may help shrink tumors caused by an aggressive type of brain cancer in children, according to new research in mice reported March 8 in Cell Reports by Johns Hopkins Kimmel Cancer Center investigators. https://medicalxpress.com/news/2024-03-rna-based-therapy-aggressive-childhood.html Wed, 13 Mar 2024 11:10:33 EDT news629547030 Nanomaterials found in consumer and health-care products can pass from the bloodstream to the brain side of a blood-brain barrier model with varying ease depending on their shape—creating potential neurological impacts that could be both positive and negative, a new study reveals. https://medicalxpress.com/news/2021-07-nanomaterials-ability-blood-brain-barrier.html Mon, 05 Jul 2021 15:00:03 EDT news544680668 Oral bacteria are ready to spring into action the moment a dental hygienist finishes scraping plaque off a patient's teeth. Eating sugar or other carbohydrates causes the bacteria to quickly rebuild this tough and sticky biofilm and to produce acids that corrode tooth enamel, leading to cavities. Scientists now report a treatment that could someday stop plaque and cavities from forming in the first place, using a new type of cerium nanoparticle formulation that would be applied to teeth at the dentist's office. https://medicalxpress.com/news/2020-08-tooth-startswithout-bacteria.html Mon, 17 Aug 2020 05:31:09 EDT news516861064 Researchers at the Center for Nanoparticle Research, within the Institute for Basic Science (IBS, South Korea), have developed a set of nanoparticles for Parkinson's disease treatment. Tested in mice and published in Angewandte Chemie as a "hot paper," this study represents the first biomedical application of nanoparticles in the clearance of reactive oxygen by-products in Parkinson's, and gives new hints of therapeutic targets. In the future, the system is expected to be used in the identification and treatment of other pathologies caused by reactive oxygen species, including: cancers, cardiovascular diseases, neurodegenerative diseases, and sepsis. https://medicalxpress.com/news/2018-07-ceria-nanoparticles-parkinson-disease-fronts.html Fri, 27 Jul 2018 08:20:02 EDT news451897830 Twinges. Painful teeth. About one in 10 people suffer from dental sensitivity caused by worn enamel. But rather than providing short-term solutions like special toothpastes or fillings, new techniques could print whole new layers of enamel onto teeth – or even stimulate the body to grow new ones. https://medicalxpress.com/news/2018-02-why-get-a-filling-when.html Tue, 20 Feb 2018 13:00:29 EST news438354021
