Researchers at The Hospital for Sick Children (SickKids) have found that intravenous morphine used alone or with a topical anaesthetic (tetracaine) effectively reduced levels of pain in newborn infants undergoing insertion of central venous catheters (central lines). This research is reported in the February 15, 2006 issue of the journal JAMA.
About 10 to 15 per cent of newborns require prolonged hospitalization for conditions such as preterm birth, congenital defects and sepsis (a blood stream infection). As part of their medical care, these infants are often exposed to multiple invasive procedures that may be painful.
"It was not so long ago that infants routinely underwent painful procedures without the benefits of analgesia. Our previous studies showed that infants do feel extreme pain, that they remember this pain and that it affects their future pain responses," said Dr. Anna Taddio, the studys lead author and principal investigator, a SickKids scientist and pharmacist, and an assistant professor of Pharmacy at the University of Toronto.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
Cardiovascular tissue engineering aims to treat heart disease with prostheses that grow and regenerate. Now, researchers from the University of Zurich, the Technical University Eindhoven and the Charité Berlin have successfully implanted regenerative heart valves, designed with the aid of computer simulations, into sheep for the first time.
Producing living tissue or organs based on human cells is one of the main research fields in regenerative medicine. Tissue engineering, which involves growing...
A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
