Purdue University researchers have simulated how over 20 different breast tissue ratios respond to heat given off by MRIs at higher field strengths than available in hospitals today.
Even tiny amounts of viruses can have disastrous consequences. RNA identification can reveal the type of virus present. A fast and sensitive technique based on optical detection has now been outlined in the journal Angewandte Chemie. Scientists from Germany and Finland have demonstrated the binding of an RNA target to a probe made of gold nanorods and a DNA origami structure. Chirality switches triggered by binding can be measured by circular dichroism spectroscopy.
A new review by the International Osteoporosis Foundation Working Group on Cancer and Bone Disease looks at the major factors affecting bone health in mematologic stem cell transplant recipients, and provides expert guidance for the monitoring, evaluation and treatment of bone loss in these patients.
Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain.
People who participate in light to moderate physical activity, such as walking at least four hours a week or swimming two to three hours a week, may have less severe strokes than people who are physically inactive, according to a study published in the Sept. 19, 2018, online issue of Neurology®, the medical journal of the American Academy of Neurology.
A multidisciplinary team of researchers at the National University of Singapore (NUS) has developed a portable, easy-to-use device for quick and accurate screening of diseases. This versatile technology platform called enVision (enzyme-assisted nanocomplexes for visual identification of nucleic acids) can be designed to detect a wide range of diseases - from emerging infectious diseases (e.g. Zika and Ebola) and high-prevalence infections (e.g. hepatitis, dengue, and malaria) to various types of cancers and genetic diseases.
'ChemLife' research initiative at the University of Konstanz makes an quintessential contribution to study of DNA polymerases.
Artificial intelligence (AI) can be an invaluable aid to help lung doctors interpret respiratory symptoms accurately and make a correct diagnosis, according to new research presented at the European Respiratory Society International Congress.
Thermal ablation is a safe, effective treatment for early-stage lung cancer, according to a new study. The results show that ablation may be an effective alternative for patients who cannot undergo lung cancer surgery because of age or health status.
International collaborative research led by Ludwine Messiaen, Ph.D., shows that while a three-base pair, in-frame deletion called p.Met992del in the NF1 gene has a mild phenotype for people with the genetic disorder neurofibromatosis type 1, or NF1, the mutation does cause complications. These include non-optic brain tumors, mostly low-grade and asymptomatic, as well as cognitive impairment and/or learning disabilities. This study extends findings first reported in 2007 that included only 19 NF1 adults.
