The new cutoff values for a metric widely used by geriatricians, physical therapists and nutritionists are more accurate, facilitate early diagnosis and contribute to preventive treatment.
The preliminary trial results of a novel radiopharmaceutical for PET imaging of inflammation developed at the University of Turku, Finland, have been published. The compound, which targets the vascular adhesion protein 1 (VAP-1) that regulates inflammatory cell traffic, is the first radiopharmaceutical that has been developed completely in Finland and has advanced to clinical trials. In the study that started with healthy volunteers, the radiopharmaceutical was found to be well tolerated and safe.
Early in the COVID-19 pandemic, doctors recognized that patients who developed a "cytokine storm" -- a surge of pro-inflammatory immune proteins -- were often the sickest. But a cytokine storm can also occur in other illnesses, such as influenza. Now, scientists report a sweat sensor that acts as an early warning system for an impending cytokine storm, which could help doctors more effectively treat patients. The researchers will present their results today at ACS Spring 2021.
New research shows that a novel positron emission tomography (PET) tracer that targets inflammation is safe and can clearly identify early stages of rheumatoid arthritis. The promising PET tracer, 68Ga-DOTA-Siglec-9, rapidly clears from blood circulation, has a low radiation dose, and can be easily produced. This first-in-human study was published in the April issue of The Journal of Nuclear Medicine.
Scientists have been exploring the cellular mechanisms underlying cancers for centuries in an attempt to successfully treat them. Collating recent research on one avenue of this exploration, the role of cell membrane receptor neuropilin-1, a review article published in Chinese Medical Journal gives a glimpse of how much we know of the disease, how much we still need to find out, and new promising treatments that we've begun to apply.
Novel insights into repair of DNA double-strand breaks (DSB), the most severe form of DNA damage, help scientists understand how proteins work to seal nicks. High resolution images show near-complete cycle of DSB detection and repair. Findings have implications in enhancing cellular response to radiation and chemotherapy.
The complex patterns of genetic ancestry uncovered from genomic data in health care systems can provide valuable insights into both genetic and environmental factors underlying many common and rare diseases--insights that are far more targeted and specific than those derived from traditional ethnic or racial labels like Hispanic or Black, according to a team of Mount Sinai researchers.
Detecting hidden genetic defects by applying an existing method to an existing datasets. Researchers at Radboud university medical center have succeeded: they showed that the 'Expansion Hunter' method can detect errors in the DNA that lead to repeat expansion diseases, such as the movement disorder ataxia. This result provides guidance to fellow researchers worldwide on how to use this method to diagnose patients with genetic disorders.
A Scientific E-Poster to be presented at the 2021 ARRS Virtual Annual Meeting found that as the United States Medical Licensing Examination (USMLE) Step 1 transitions from a numerical score to pass or fail--as early as January 2022--radiology residency program directors will likely rely on USMLE Step 2 Clinical Knowledge (CK) scores as an objective and standardized metric to screen applicants.
A Scientific E-Poster to be presented at the 2021 ARRS Virtual Annual Meeting found that in the setting of a high pretest probability of COVID-19 infection or with a quick turnaround of the rapid real-time reverse transcriptase-polymerase chain reaction (RT-PCR) COVID-19 test, a chest x-ray (CXR) scoring system may be used prospectively to predict patient outcomes.t
