A novel method for recycling PLA using low-temperature, low-pressure reactions with alcohol or water has been discovered by Zeus Research. PLA is used today in many applications ranging from food packaging to implantable medical devices. Because of its sensitivity to thermal degradation, PLA is difficult to recycle and actually becomes a contaminant in the plastics stream of municipal solid waste.

Researchers have designed the first neurosurgical robotic system capable of performing bilateral stereotactic neurosurgery inside a magnetic resonance imaging (MRI) scanner. The MRI-guided robot facilitates less-invasive stereotactic procedures on the patient under general anesthesia because surgeons can accurately control and evaluate the stereotactic manipulation bilaterally to the left and right brain targets in real time. This innovative technological breakthrough can facilitate the treatment of Parkinson’s disease and other neuropsychiatric disorders.

DBS therapy, like a heart pacemaker, can deliver electrical signals through implanted electrodes to the deep brain targets. It helps to restore normal nerve cell activity. Conventional DBS is performed while the patient is awake under local anesthesia. Surgeons have to rely on verbal or physical interactions with the patients to ensure the electrode placement is going well. This surgery demands accuracy in order to target only the tiny nucleus structures and not damage the surrounding critical tissue. Without the intra-operative updates of a surgical “roadmap,” the brain may shift after the skull is opened, which inevitably lowers the targeting accuracy.

Researchers have created an automated blood drawing and testing device that provides rapid results, potentially improving the workflow in hospitals and other health-related institutions to allow healthcare practitioners to spend more time treating patients.

“This device represents the holy grail in blood testing technology,” says Martin L. Yarmush, senior author of the study and Paul & Mary Monroe Endowed Chair & Distinguished Professor in the Department of Biomedical Engineering at Rutgers University–New Brunswick. “Integrating miniaturized robotic and microfluidic (lab-on-a-chip) systems, this technology combines the breadth and accuracy of traditional blood drawing and laboratory testing with the speed and convenience of point-of-care testing.”

Early detection has been shown to increase breast cancer survival rates, but many women avoid having their mammograms taken as often as they should because of the discomfort involved. Researchers say they have developed something better: a laser-sonic scanner that can find tumors in as little as 15 seconds by shining pulses of light into the breast. The scanning system, known as photoacoustic computed tomography, or PACT, was developed in the lab of Lihong Wang, Caltech’s Bren Professor of Medical Engineering and Electrical Engineering.

PACT works by shining a near-infrared laser pulse into the breast tissue. The laser light diffuses through the breast and is absorbed by oxygen-carrying hemoglobin molecules in the patient's red blood cells, causing the molecules to vibrate ultrasonically. Those vibrations travel through the tissue and are picked up by an array of 512 tiny ultrasonic sensors around the skin of the breast. The data from those sensors are used to assemble an image of the breast's internal structures in a process that is similar to ultrasound imaging, though much more precise. PACT can provide a clear view of structures as small as a quarter of a millimeter at a depth of 4 centimeters. Mammograms cannot provide soft-tissue contrast with the level of detail in PACT images, Wang says.

ICU Medical, Inc., which makes medical devices used in infusion therapy and critical care applications, has become the first medical device manufacturer to obtain certification under the UL Cybersecurity Assurance Program (UL CAP), a new cybersecurity management program from UL designed to minimize risks by creating standardized, testable criteria for assessing software vulnerabilities and weaknesses to help reduce exploitation, address known malware, enhance security controls, and expand security awareness.

This presentation will describe the benefits of parametric release and how best to establish a compliant and capable process design. Topics covered include:

With a rapidly aging population and increased incidence of cardiovascular disease, stroke is becoming one of the leading causes of morbidity and mortality in the United States and across the world. Up to 80 percent of strokes can be prevented but currently there is no way to assess and monitor the risk of stroke at home.

Researchers have developed an integrated system for early diagnosis of diseases using wearable monitors. Able to continuously monitor physiological indicators without disturbing the user, the system can repair itself in the event of a tear or scratch, and receives the energy required for operation from the wearer.

This could help spare patients much pain and suffering, greatly reduce medical expenses, and provide extensive and detailed information for epidemiological studies.

A new device could streamline the drug-testing process to speed the development of new medicines to treat pulmonary fibrosis. The technology mimics the damaging effects of lung fibrosis.

The innovation relies on the same technology used to print electronic chips, photolithography. Only instead of semiconducting materials, researchers placed upon the chip arrays of thin, pliable lab-grown lung tissues — in other words, its lung-on-a-chip technology.
