Synchrotron Radiation Illuminates How Babies’ Protective Bubble Bursts

07.11.2007
Researchers at the University of Reading, School of Pharmacy have developed an important new technique to study one of the most common causes of premature birth and prenatal mortality. The findings are published in the November 7 issue of the online, open-access journal PLoS ONE.

Dr Che Connon, a Research Councils UK Fellow in Stem Cells and Nanomaterials, and his team used a powerful X-ray beam to examine tiny structures within the protective sac - amniotic membrane - which surrounds the developing baby.

This beam can resolve structures far smaller than a light or electron microscope. Furthermore, unlike other more intrusive forms of microscopy, X-ray investigation requires no processing of the tissue before examination, so can produce an accurate measurement of amniotic membrane structure in its normal state.

When the protective sac raptures during labour this is when the mother’s waters burst; if premature rupture occurs it can result in death or mental retardation of the child. Currently premature birth is increasing and 40% are attributed to the early rupture of amniotic membranes. Thus, a better understanding of the rupture process will lead to better treatment, earlier diagnosis and fewer premature deliveries

Dr Connon, an expert in tissue structure, said: “This is of interest to the general public because amniotic membrane rupture is an important stage in the start of labour. More importantly early rupture of the amniotic membranes occurs in up to 20% of all pregnancies worldwide, and is the most common cause of preterm birth, leading to babies dying or having major problems such as cerebral palsy. The paper describes a new breakthrough in understanding the structure of amniotic membranes and how they rupture. Hopefully this will lead to therapies designed to prevent preterm membrane rupture as well.”

“Rupture of amniotic sac has been associated with a weakening of the tissue, but there is very little information available concerning the detailed mechanics of how this actually occurs.”

“We have now identified a regular cross-work arrangement of fibre forming molecules within the amniotic membrane which give the tissue its strength. Furthermore we have detected nanoscale alterations in the molecular arrangement within areas associated with amniotic membrane rupture. These results suggest, for the first time, that it is the loss of this molecular lattice like arrangement that governs the timing of membranes rupture.”

“Therefore, by controlling the amniotic membranes molecular arrangement we believe we can prevent premature rupture and delivery in the future.”

Im Focus: Temperature-controlled fiber-optic light source with liquid core

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...

Im Focus: AchemAsia 2019 will take place in Shanghai

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...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

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.

Im Focus: Sharp images with flexible fibers

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.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
