A "metal foam" developed by North Carolina State University researchers could mean a new generation of biomedical implants that would avoid bone rejection that often results from more rigid implant materials, such as titanium. The metal foam is lighter than solid aluminum and can be made...

University of Michigan engineers have developed an artificial foot that recycles energy otherwise wasted in between steps, which could make it easier for amputees to walk. A typical prosthesis doesn't reproduce the force a living ankle exerts to push off of the ground. As a result, test subjects...

Johns Hopkins University biomedical engineers, working with colleagues at Seoul National Laboratory in Korea, have produced a laboratory chip with nanoscopic grooves and ridges capable of growing cardiac tissue that more closely resembles natural heart muscle. The scientists say this chip could be used to design new...

Johns Hopkins University researchers have developed biodegradable nanosized particles that can bypass the body's mucus secretions to deliver a sustained-release medication cargo. The nanoparticles, which degrade over time into harmless components, could someday be used to carry life-saving drugs to individuals suffering...

A constant-force resistive exercise unit (CFREU) has been invented for use in both normal gravitational and microgravitational environments. In comparison with a typical conventional exercise machine, this CFREU weighs less and is less bulky: Whereas weight plates and associated bulky supporting structures...

Oral mucosal drug delivery is an alternative method of systemic drug delivery that offers several advantages over both injectable and enteral methods. Since the oral mucosa is highly vascularised, drugs that are absorbed through the oral mucosa directly enter the systemic circulation,...

As the number of investigational and approved vaccines continues to increase, the frequency of vaccinations will soon reach a practical limit. The development of combination vaccines is a common practice that addresses the concern of repeated visits to the clinic by reducing the total number of...

A new type of sensory feedback system for a myoelectrically controlled biomimetic prosthetic hand was developed. One of the characteristic features of the human neuromuscular control system is the increase in the compliance around a joint with decreasing activity of a muscle....

Hospira (Lake Forest, IL) has introduced the GemStar® SP infusion system with GemStar™ Infusion Suite software. The system is designed to help caregivers better incorporate patient safety best practices at the patient’s bedside. The GemStar Infusion Suite software is a standalone PC-based application that enables efficient and...
