New Technique for Cheaper, More Efficient Single Cell Sequencing

by Medgadged • 2017/02/23 • 0 Comments

Single-cell sequencing has shown a lot of promise in identifying genetic differences between cells in a given tissue sample. It is particularly useful for understanding heterogeneity and evolution in resected tumors, and is increasingly used for improving precision medicine approaches. Unfortunately, conventional methods are cost-prohibitive, thus they restrict the cell numbers that can be assessed […]

Adaptive Liquid Lenses and Smartphones Shrink Digital Pathology Into a Tiny Portable Device

by Medgadged • 2017/02/15 • 0 Comments

At Ohio State University researchers have developed a portable pathology slide scanner that uses a smartphone to image, display, and share the scans. Unlike conventional microscopy, digital pathology devices image the entire slide and therefore provide a much wider field of view. This makes it easier to identify tissues that may be a and indicator […]

Cheap Method for Printing Lab-on-Chip Devices Promises Diagnostic Revolution

by Medgadged • 2017/02/09 • 0 Comments

Scientists at Stanford University have developed a new method of manufacturing lab-on-chip devices that cost only pennies to make, which can be used for research and point-of-care diagnostics, particularly in poorer places around the world. The investigators built such devices and showed that they can be used to separate cells from a sample, isolate target […]

New Imaging Technique Provides Quick Tumor Diagnosis During Brain Surgeries

by Medgadged • 2017/02/08 • 0 Comments

If a tumor is suspected during brain surgery, it takes 30-40 minutes from the time of removing the sample from the patient’s brain to the time of diagnosis. The sample is taken through a rigorous process of tissue sectioning, staining, mounting, and interpretation by pathologists. Researchers from University of Michigan have now developed an imaging […]

A Breathalyzer to Detect Inflammatory Signs of Influenza Infection

by Medgadged • 2017/02/03 • 0 Comments

Detecting diseases non-invasively by sampling exhaled breath is a growing field. Previously, we featured Owlstone Medical, who have developed breath sampling devices to store breath samples for later analysis along with an integrated unit for the detection of lung cancer biomarkers. Recent research on breath testing has suggested that viral infections, such as influenza, might be […]

PerkinElmer’s New Vectra Polaris Automated Quantitative Pathology System for Studying Cancer Immunotherapies

by Medgadged • 2017/02/02 • 0 Comments

PerkinElmer is releasing a new automated quantitative pathology system, the Vectra Polaris. It was developed to help study how cancer immunotherapies are affecting their targets and nearby tissues. The machine is able to detect multiple immunohistochemical stains simultaneously thanks to multispectral imaging using seven colors, allowing for more complicated studies that identify interesting correlations. The slides […]

Tiny Acoustofluidic Chip Separates Nanoparticles from Liquid Samples to Detect Disease

by Medgadged • 2017/01/30 • 0 Comments

Scientists at Duke University have developed a way of concentrating nanoparticles inside a small device using only sound waves. This achievement may help introduce portable diagnostics that rely on attaching nanoparticles to biomarkers such as proteins and measuring how many find their targets. There is now a large selection of nanoparticles, and ways to attach […]

Lens-Free Automated Cell Counting System for Diagnosis of Meningitis

by Medgadged • 2017/01/27 • 0 Comments

French researchers from Grenoble Alpes University and Aix-Marseille University have developed an automated lens-free microscopy technique for counting and telling apart red and white blood cells withing cerebrospinal fluid. Cerebrospinal fluid, gathered through a spinal tap, should be clear and have few, if any, blood cells within it. Patients with meningitis, due to inflammation and […]
