About half of the 700,000 annual cases of suspected appendicitis in the United States lack the usual symptoms – pain in the lower right abdomen, fever and a rising white blood cell count – making the decision to operate somewhat problematic. Now, thanks to a new imaging agent based on technology developed by nuclear medicine researchers at Thomas Jefferson University in Philadelphia, doctors may finally have a way to rapidly and accurately detect those hard-to-diagnose cases.
The U.S. Food and Drug Administration has approved NeutroSpec, a monoclonal antibody that binds to a type of infection-fighting white blood cell, for use in patients five years and older who have inconclusive symptoms of appendicitis.
NeutroSpec is “radiolabeled,” meaning it carries technetium, a radioactive substance. When injected into the blood, NeutroSpec finds and binds to a certain receptor on neutrophils, white blood cells that the body uses to fight infection. Doctors can then locate the antibody and the infection site by using a device called a gamma camera. In case of hard to diagnose cases, the gamma camera pictures allow doctors to accurately see if the appendix is infected or not and permits them to treat the cause appropriately.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
Faster and secure data communication: This is the goal of a new joint project involving physicists from the University of Würzburg. The German Federal Ministry of Education and Research funds the project with 14.8 million euro.
In our digital world data security and secure communication are becoming more and more important. Quantum communication is a promising approach to achieve...
On Saturday, 10 November 2018, the research icebreaker Polarstern will leave its homeport of Bremerhaven, bound for Cape Town, South Africa.
When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure
Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...
