In an important step toward endoscopic diagnosis of cancer, researchers have developed a handheld fibre optic probe that can be used to perform multiple nonlinear imaging techniques without the need for tissue staining. The new multimodal imaging probe uses an ultrafast laser to create nonlinear optical effects in tissue that can reveal cancer and other […]
A new technique developed by researchers at Lawrence Livermore National Lab promises to improve accuracy and lower costs of real-time assessment of kidney function, reports an article published this week by SPIE, the international society for optics and photonics. The paper explores the use of multimodal autofluorescence and light scattering to evaluate functional changes in […]
The fight against skin cancer just got a new weapon. For years, melanoma researchers have studied samples that were considered uniform in size and colour, making them easier to examine by more conventional means. But melanomas don’t always come in the same shape and hue; often, melanomas are irregular and dark, making them difficult to […]
A synthetic, soft tissue retina developed by an Oxford University student could offer fresh hope to visually impaired people. Until now, all artificial retinal research has used only rigid, hard materials. The new research, by Vanessa Restrepo-Schild, a 24-year-old doctoral student and researcher at Oxford University’s Department of Chemistry, is the first to successfully use […]
A recent study, affiliated with UNIST has proposed the possibility of in situ human health monitoring simply by wearing a contact lens with built-in wireless smart sensors. This study has been jointly conducted by Professor Jang-Ung Park of Materials Science and Engineering, Professor Chang Young Lee of Life Science, and Professor Franklin Bien of Electrical […]
Chemists at The University of Texas at Austin have developed a material that holds the key to cheap, fast and portable new sensors for a wide range of chemicals that right now cost government and industries large sums to detect. The innovation could lead to major public health gains, as it holds the potential to […]
Results of a definitive clinical trial show that a new, disposable diagnostic patch effectively detects obstructive sleep apnoea across all severity levels. Results show that the total rate of clinical agreement between the patch and standard in-lab polysomnography was 87.4 percent with 95 percent confidence interval of 81.4 percent to 91.9 percent. According to the […]
A new study finds that about one in three patients admitted to the hospital exhibits symptoms of depression, potentially affecting their clinical outcomes. Depressive symptoms can delay recovery time, increase length of hospital stays, and increase the frequency of readmissions, for example. The findings suggest that screening hospitalized patients for depression should be as routine […]
Using computed tomography (CT) to evaluate muscle health may help identify optimal treatments for older patients who fall and break their hips, a new study led by radiologists from UC Davis and Wake Forest Baptist medical centres has found. The research specifically showed that decreased ‘core’ muscle that stabilizes the spine was associated with decreased […]
Breast-conserving surgery (BCS) is the primary treatment for early-stage breast cancer, but more accurate techniques are needed to assess resection margins during surgery to avoid the need for follow-up surgeries. Now, in a first-in-human study, British researchers have provided a possible solution using Cerenkov luminescence imaging (CLI), which combines optical and molecular imaging by detecting […]
