It takes two to fight cancer


New research at the Institute of Food Research shows that two food components recognised for their ability to fight cancer are up to 13 times more powerful when put to work together. The results are published in the latest issue of international journal Carcinogenesis.

The study focuses on genes that play an important role in tumour formation, tumour progression, and the spread of tumour cells. The food components sulforaphane and selenium were found to have an increased impact on these genes when used as a combined treatment.

“As a result of this research, we hope to begin a human cancer prevention trial next year. It opens up new possibilities for functional foods, food supplements or simply new guidelines for healthy eating”, says Dr Yongping Bao, senior researcher at the IFR.

Sulforaphane is found at high concentrations in broccoli, sprouts, cabbage, watercress and salad rocket. Selenium-rich foods include nuts, poultry, fish, eggs, sunflower seeds and mushrooms.

The plant chemical sulforaphane is recognised not only for its powerful role in cancer prevention, but also as a potentially useful curative cancer drug.

Selenium is an essential mineral and its deficiency is associated with the incidence of many types of cancers, including prostate cancer. The UK dietary intake has halved over the last 20 years and British bread-making wheat contains 10 to 50 times less selenium than that in the US and Canada.

“High concentrations in the diet are normally required to protect against cancer, but when these compounds act synergistically lower doses are needed to prevent cancer formation. This is particularly good news as selenium and sulforaphane can be toxic at high levels”, says Dr Bao.

The research demonstrates the complex interactions between food components and the limitations to studying them in isolation. “IFR is committed to a whole food approach, reflecting the way that nutrient and non-nutrient components are eaten in every day life”, says Director of IFR, Professor Alastair Robertson.

At the 2018 ILA Berlin Air Show from April 25–29, the Fraunhofer Institute for Laser Technology ILT is showcasing extreme high-speed Laser Material Deposition (EHLA): A video documents how for metal components that are highly loaded, EHLA has already proved itself as an alternative to hard chrome plating, which is now allowed only under special conditions.

When the EU restricted the use of hexavalent chromium compounds to special applications requiring authorization, the move prompted a rethink in the surface...

Im Focus: Radar for navigation support from autonomous flying drones

At the ILA Berlin, hall 4, booth 202, Fraunhofer FHR will present two radar sensors for navigation support of drones. The sensors are valuable components in the implementation of autonomous flying drones: they function as obstacle detectors to prevent collisions. Radar sensors also operate reliably in restricted visibility, e.g. in foggy or dusty conditions. Due to their ability to measure distances with high precision, the radar sensors can also be used as altimeters when other sources of information such as barometers or GPS are not available or cannot operate optimally.

Drones play an increasingly important role in the area of logistics and services. Well-known logistic companies place great hope in these compact, aerial...
