Estimates of numbers vary, but most experts agree that around 1 woman in 13 in the UK will have thyroid disease, with the figure increasing for older women. Figures being presented at the Birmingham meeting will show indicate that a tendency to thyroid disease is even more common in older cats.
In humans, low thyroid activity is common, but in cats having an overactive thyroid is a more common problem. Apart from humans, cats are the only species where non-cancerous hyperthyroidism has been recorded. Hyperthyroidism in cats was first reported in the late 1970s and has since been recognised as the most common hormonal disease of older cats.
Dr Jenny Wakeling’s research at the Royal Veterinary College (London), studied 100 cats over 8 years of age, visiting a veterinary practice for routine health checks. The thyroid hormone measurements were repeated after a period of about a year.
They found that in apparently healthy older cats – cats more than 8 years old – around 6% of cats had hyperthyroidism. In addition 20% had subclinical hyperthyroidism – in other words they had an abnormal thyroid function, but not the full-blown disease. However the research also showed that cats with subclinical hyperthyroidism had a high risk of becoming hyperthyroid within 18 months.
In 1999, Cats Protection estimated that there are 5 million domestic cats in the UK, not including stray and feral cats. It’s not known how many of these are more than 8 years old.
Dr Wakeling said:
"What this means is that around a quarter of older cats – older than around 8 years - will either have thyroid disease, or have a tendency to develop it. It’s something that owners need to keep an eye on.
"You tend to notice it if your cat is eating a lot but losing weight. Then you may pick up other symptoms, such as hyperactivity, fast heart rate, and a poor coat. You might also find that the cat gets stressed and angry more easily. This can easily be treated, and if in doubt you should take your cat along to your vet for a blood test. It’s not only humans who get hormonal problems."

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
