Tumour-imaging nanosystem to improve diagnostic imaging

Tumour-imaging nanosystem to improve diagnostic imaging
Researchers at Sanford Burnham Prebys Medical Discovery Institute (SBP) have developed a proof-of-concept nanosystem that dramatically improves the visualisation of tumours. Published in Nature Communications, the platform achieves a five-fold increase over existing tumor-specific optical imaging methods. The novel approach generates bright tumor signals by delivering “quantum dots” to cancer cells without any toxic effects.

'Pen' device accurately identifies cancer in seconds

'Pen' device accurately identifies cancer in seconds
A powerful tool that rapidly and accurately identifies cancerous tissue during surgery has been invented by a team of scientists and engineers at The University of Texas at Austin. The tool delivers results in about ten seconds - more than 150 times as fast as existing technology. The MasSpec Pen is an innovative handheld instrument that gives surgeons precise diagnostic information about what tissue to cut or preserve, helping improve treatment and reduce the chances of cancer recurrence.

Selfies could screen for pancreatic cancer

Selfies could screen for pancreatic cancer
Pancreatic cancer has one of the worst prognoses - with a five-year survival rate of 9% - in part because there are no telltale symptoms or non-invasive screening tools to catch a tumor before it spreads. Now, University of Washington researchers have developed an app that could allow people to easily screen for pancreatic cancer and other diseases - by snapping a smartphone selfie.

AI predicts dementia before onset of symptoms

AI predicts dementia before onset of symptoms
Imagine if doctors could determine, many years in advance, who is likely to develop dementia. Such prognostic capabilities would give patients and their families time to plan and manage treatment and care. Thanks to artificial intelligence research conducted at McGill University, this kind of predictive power could soon be available to clinicians everywhere.

Self-powered ‘SPEDs’ may lead to medical-diagnostic tools

Self-powered ‘SPEDs’ may lead to medical-diagnostic tools
A new medical-diagnostic device made out of paper detects biomarkers and identifies diseases by performing electrochemical analyses - powered only by the user’s touch - and reads out the color-coded test results, making it easy for non-experts to understand. “You could consider this a portable laboratory that is just completely made out of paper, is inexpensive and can be disposed of through incineration,” said Ramses V. Martinez, an assistant professor of industrial and biomedical engineering at Purdue University.

Retinal imaging can improve Alzheimer’s detection

Retinal imaging can improve Alzheimer’s detection
A team of researchers at Cedars-Sinai Medical Center in Los Angeles and NeuroVision Imaging, a Sacramento, California firm, have developed a retinal imaging system that could allow early detection of Alzheimer’s disease. One of the hallmarks of Alzheimer’s disease is the accumulation of beta-amyloid protein in the brain. There are numerous ways to monitor levels of beta-amyloid in the nervous system, including cerebrospinal fluid analysis, or imaging techniques like positron emission tomography.

Blood test predicts prostate tumour resistance

Blood test predicts prostate tumour resistance
When bacteria develop antibiotic resistance, treatment with these medications becomes ineffective. Similarly, tumour cells can also change in such a way that renders them resistant to particular medications. This makes it vitally important for cancer patients and their doctors to determine as early as possible whether a specific therapy is working or not. A new blood test developed by researchers at the Technical University of Munich (TUM) can predict drug resistance in patients with advanced prostate cancer.

AFE enables wearing your heart rate on your sleeve

AFE enables wearing your heart rate on your sleeve
The MAX30004 biopotential analogue front-end (AFE) from Maxim Integrated is in stock at Mouser Electronics. The device is a single-channel biopotential heart-rate detection AFE solution for wearable medical applications, such as chest bands and single-lead wireless patches for heart rate monitoring. It eliminates the need to extract and process electrocardiogram (ECG) data on its microcontroller for high-motion environments.
