State University of New York (SUNY) Chancellor John B. King Jr. today announced that this technology is a recipient of the latest round of seed funding through the SUNY Technology Accelerator Fund (TAF), which provides grants to faculty inventors and scientists. The inventors have developed a portable handheld spectral reflection (PHASR) scanner that is alignment-free and can acquire three-dimensional spectroscopic images in the terahertz range of 0.1-3 THz. The PHASR scanning device uses an asynchronous optical sampling system to achieve short scan times and is attached only by an umbilical. The device’s portability and quick scan times allow it to be used in clinical settings where previous devices could not be used. The device has been used to characterize burn injuries in animal studies, and a human clinical trial is planned to further test its use for diagnosing burn wounds and predicting wound-healing outcomes.
University Hospitals Cleveland Medical Center has been awarded a five-year, $56.25 million cooperative agreement from the Health Resources and Services Administration (HRSA) – $11.25 million annually – to lead the newly established Pediatric Prevention Network (PPN). It is the largest grant UH has ever received and marks a major national investment in pediatric emergency preparedness.
About the Study: In this multicenter qualitative study, differences in the relationship between palliative care and oncology teams were identified that may mechanistically affect end-of-life patient outcomes. These findings are important to ensure the delivery of high-quality care for all patients with cancer.
An NIH-funded scientific team has shown that a new brain-computer interface (BCI) can allow people with vocal tract and bodily paralysis to convey both speech and upper-body gestures simultaneously. While BCIs have facilitated one or the other in the past, this new system is the first to enable both modes of communication at once, more closely replicating natural expression.
New research from UBC's Centre for Molecular Medicine and Therapeutics and BC Children's Hospital Research Institute explains why some people with Huntington disease develop symptoms a decade earlier and points to a promising treatment target.
