When a breast tumor is detected, many women opt to have a lumpectomy, which is surgery designed to remove the diseased tissue while preserving the breast. But during this procedure, doctors cannot learn right away whether all of the cancerous tissue has been removed, with no microscopic signs that cancer cells were left behind.
To reduce the need for second surgeries, four Johns Hopkins graduate students have designed a device to allow pathologists to quickly inspect excised breast tissue within 20 minutes, while the patient is still in the operating room. If this inspection indicates that the tumor was not fully removed, additional tissue can then be removed during the same operation.
On this episode of The Pulse, a major step toward an artificial pancreas, detecting disease from just one drop blood, creating mature human cardiac patches from human heart cells, and a smart sock that helps runners improve their technique and prevent injuries.
People who have a traumatic brain injury (TBI) may be more likely to have a future stroke, according to research that appears in the June 26, 2013, online issue of Neurology®, the medical journal of the American Academy of Neurology.
The antibacterial effects of silver are well established. Now, researchers at Yonsei University in Seoul, Republic of Korea, have developed a technique to coat glass with a layer of silver ions that can prevent growth of pathogenic bacteria including Escherichia coli, Salmonella typhimurium and Campylobacter jejuni. The technology could be used to protect medical equipment.
The Society of Women Engineers, along with the American Society of Mechanical Engineers recently honored Noha S. El-Ghobashy with the Kenneth Andrew Roe Award. El-Ghobashy is an inspiring humanitarian working tirelessly to bring opportunities and advancement to underdeveloped nations.
Engineers and biologists at the University of Sheffield have shown how a recent theory-- that skin has 'sleeping' stem cells which can be woken up when required-- best explains how our skin constantly regrows. The research-- conducted in collaboration with The Procter & Gamble Company (P&G), makers of Olay, and published in Nature Scientific Reports-- has implications for combating the effects of aging and perhaps even skin cancer.
Our present understanding of thermodynamics is fundamentally incorrect if applied to small systems and needs to be modified, according to new research from University College London (UCL) and the University of Gdańsk. The findings, published today in Nature Communications, have wide applications in small systems, such as biological motors and systems found in the body.
St. Jude Medical, Inc. (NYSE:STJ), a global medical device company, today announced regulatory approval from the Japanese Ministry of Health, Labor and Welfare (MHLW) and launch of the Accent MRI ™ Pacemaker and the Tendril MRI ™ lead.

This draft guidance document provides draft recommendations for complying with special controls being proposed to support reclassification of the Implanted Blood Access Devices for Hemodialysis into class II (special controls). The device, as proposed...
Available immediately are 6 new analog Z-Drive models with increased current output of 60A peak and 30A continuous designed with the same footprint and pin functionality as the previous 40A versions. These new servo drives provide 50% more power in the same space, making upgrades in power output a simple drop-in replacement.
Galil Motion Control has announced the latest product in their RIO Pocket PLC Series. The new RIO-47300 includes more I/O, screw terminals and two Ethernet ports which allow management of an unlimited number of inputs and outputs without an external Ethernet switch.
At the 2013 International Forum on Design for Manufacture and Assembly (DFMA), Boothroyd Dewhurst announced the release of its DFA Product Simplification software, Version 10. The Design for Assembly software has an improved user interface for speed and ease of use, and helps manufacturers develop more streamlined and profitable products.
Multifunctional devices such as tablets, ultrabooks and even smartphones need high brightness levels and good color rendering without draining the batteries too quickly. The new MicroSideled 3806 from Osram Opto Semiconductors is designed specifically to meet these requirements.
CEA-Leti and nine partners in the NEPHRON+ project are developing an artificial kidney that would provide a major improvement in treating patients with chronic kidney failure. The goal is a next-generation, integrated system that allows real-time, continuous, multiparametric monitoring of the patient and the device via sensors developed by Leti and its partners.
