Juice extracted from North American lowbush blueberries, biotransformed with bacteria from the skin of the fruit, holds great promise as an anti-obesity and anti-diabetic agent.
The study, published in the International Journal of Obesity, was conducted by researchers from the Université de Montréal, the Institut Armand-Frappier and the Université de Moncton who tested the effects of biotransformed juices compared to regular blueberry drinks on mice.
"Results of this study clearly show that biotransformed blueberry juice has strong anti-obesity and anti-diabetic potential," says senior author Pierre S. Haddad, a pharmacology professor at the Université de Montréal's Faculty of Medicine. "Biotransformed blueberry juice may represent a novel therapeutic agent, since it decreases hyperglycemia in diabetic mice and can protect young pre-diabetic mice from developing obesity and diabetes."
The scientists tested the effect of biotransformed blueberry juice on a group of mice prone to obesity, insulin resistance, diabetes and hypertension. Incorporating biotransformed blueberry juice into the water of mice reduced their food intake and their body weight. "These mice were an excellent model that closely resembles obesity and obesity-linked type 2 diabetes in humans," says Dr. Haddad, who is also director of the CIHR Team in Aboriginal Anti-Diabetic Medicines at the Université de Montréal.
Biotransformation of the blueberry juice was achieved with a new strain of bacteria isolated from the blueberry flora, specifically called Serratia vaccinii, which increases the fruit's antioxidant effects. "The identification of the active compounds in biotransformed blueberry juice may result in the discovery of promising new antiobesity and antidiabetic molecules," says Dr. Haddad.
As for the impact of blueberry products on diabetes, says Tri Vuong, lead author and recent PhD graduate from the Université de Montréal's Department of Pharmacology: "Consumption of fermented blueberry juice gradually and significantly reduced high blood glucose levels in diabetic mice. After three days, our mice subjects reduced their glycemia levels by 35 percent."

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.
