Researchers at the University of Warwick, and the University Hospitals Coventry and Warwickshire NHS Trust, have devised a new sensor which dramatically improves the amount of early warning doctors and midwives get of a dangerous situation in the birth process when the unborn child’s brain is starved of oxygen - Fetal Hypoxia.
The threat of fetal hypoxia carries dangers not only for the child but also for the woman giving birth as doctors often proceed quickly to a caesarean section if they feel there is a significant threat of fetal hypoxia. However current tests for this condition require blood samples to be taken to a lab for examination leading to delays which means doctors having to decide sometimes to proceed with a cesarean section rather than take the risk on waiting on that full analysis.
University of Warwick researcher Professor Nick Dale had been looking at the science surrounding a chemical that can be found in blood called hypoxanthine. An unborn child with more than 5 micromoles (5 millionths of a mole) of hypoxanthine per litre of their blood is at severe risk of fetal hypoxia. Professor Dale was frustrated at the lack of effective instrumentation available to detect and study this chemical and devised his own fine tuned probe to examine the chemical. On talking with colleagues in the University of Warwick’s Medical School and University Hospitals Coventry and Warwickshire NHS Trust they pointed out that the probes would be of massive benefit to doctors in the delivery room.
Warwick Medical School researchers have examined the probes and say that the use of Professor Dale’s probes to test for hypoxanthine would give doctors in delivery rooms almost instant data on whether the unborn child faced fetal hypoxia. This would allow doctors to take more informed decisions as to whether to proceed to a caesarean section and probably therefore reduce the number of caesareans conducted. Another advantage is that Professor Dale’s test also requires much less fine tuning than current tests (the blood PH test currently used to detect fetal hypoxia problems needs to identify a shift of as little of 0.05 PH).
Professor Dale is thrilled by the medical interest in his probes and is now working through a spin-out company Sarissa Biomedical Ltd - to take the work further. Sarissa is already talking with a number of medical instrument manufacturers and aims to establish a partnership between Sarissa, a medical instrument manufacturer and venture capitalists to produce a full blown medical instrument using the new probes and then to take it to full clinical trials in hospital delivery rooms.

At the Hannover Messe 2018, the Bundesanstalt für Materialforschung und-prüfung (BAM) will show how, in the future, astronauts could produce their own tools or spare parts in zero gravity using 3D printing. This will reduce, weight and transport costs for space missions. Visitors can experience the innovative additive manufacturing process live at the fair.
Powder-based additive manufacturing in zero gravity is the name of the project in which a component is produced by applying metallic powder layers and then...
Physicists at the Laboratory for Attosecond Physics, which is jointly run by Ludwig-Maximilians-Universität and the Max Planck Institute of Quantum Optics, have developed a high-power laser system that generates ultrashort pulses of light covering a large share of the mid-infrared spectrum. The researchers envisage a wide range of applications for the technology – in the early diagnosis of cancer, for instance.
Molecules are the building blocks of life. Like all other organisms, we are made of them. They control our biorhythm, and they can also reflect our state of...
University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
