Leprosy, tuberculosis, and peanuts


Nitric oxide is a natural part of the body’s immune defense. Linköping University researcher Thomas Schön has studied this compound in connection with the skin disease leprosy and the lung disease tuberculosis. The Swedish researcher has found that nitric oxide probably contributes to the disease in the case of leprosy but, on the other hand, plays a positive role in protecting against tuberculosis. This role can be reinforced by adding a supplement of arginine, which is found in peanuts, for example.

“The production of nitric oxide is high in both leprosy and tuberculosis patients. As regards leprosy, this nitric oxide can have a certain effect of killing off germs in the initial stages of the disease. But it does not always impede the development of the sickness, and in later stages it can even be seen as aggravating skin lesions,” says Thomas Schön.

He has run field studies in Ethiopia, a country where leprosy and tuberculosis often occur. In Ethiopia he studied the results of a synthetic dietary supplement of the amino acid arginine in tuberculosis patients. Arginine is needed to maintain the body’s production of nitric acid, and the supplemental arginine did in fact lead to a reduction of symptoms and a shorter contagious period among the Ethiopian patients.

“Arginine is found in peanuts, among other foods. Eating a supplement of peanuts should thus bolster the body’s defenses against tuberculosis. A simple food supplement like that may be a simple and cheap way to improve the treatment of the disease in poor countries,” says Thomas Schön. He hopes to be able to continue his research by testing this theory in practice.

Tuberculosis most often affects the lungs, killing more than two million people every year around the world. The disease has also reappeared in Sweden, partly because of the prevalence of antibiotics-resistant tubercular bacteria in the Baltic countries and Russia.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Terahertz excitation of selected crystal vibrations leads to an effective magnetic field that drives coherent spin motion

Controlling functional properties by light is one of the grand goals in modern condensed matter physics and materials science. A new study now demonstrates how...

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
