New knowledge of skeletal diseases in rapidly-growing dog breeds

04.09.2008
Can. med. vet. Cathrine Trangerud defended her thesis for the degree of Philosophiae Doctor at the Norwegian School of Veterinary Science on August 22, 2008, entitled "Growth patterns and metaphyseal irregularities in dogs: a study of 4 large breeds with emphasis on irregularities in the distal metaphysis of the radius and ulna in Newfoundland dogs".

The degree studied the relationship between the speed of growth of young dogs and the development of common skeletal diseases such as elbow dysplasia and hip dysplasia. A common conception is that rapidly-growing breeds have a greater risk of developing certain types of skeletal illness. However, no comprehensive research has been conducted in dogs in a domestic environment to establish this.

This thesis is the result of a study of some seven hundred dogs of four different breeds that lived at home with their owners. The dogs were followed closely from birth until the age of two years. Weight was measured, blood samples were collected, and the lower forelimbs were x-rayed several times.

Normal growth curves have now been established for these breeds for the first time. It turns out that the four breeds have different patterns of growth and that bitches grow more slowly than dogs (males).

Surprisingly, the study showed that the Labrador retriever grows faster than the Newfoundland, Irish wolfhound and the Leonberger, indicating that the largest breeds do not necessarily grow the fastest. The predominating view of the correlation between rapid growth and high incidence of common skeletal diseases therefore has to be revised.

Through her doctoral work, Trangerud discovered a new condition in the skeleton of the Newfoundland, which she found in nearly half of the young dogs. The condition resembles human bone dysplasia, but it is presently unclear just what clinical consequences the condition has for affected dogs.

Im Focus: New studies increase confidence in NASA's measure of Earth's temperature

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.

The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...

Im Focus: The geometry of an electron determined for the first time

Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.

The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

Im Focus: Quantum Cloud Computing with Self-Check

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.

Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...

Im Focus: Accelerating quantum technologies with materials processing at the atomic scale

'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.

However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
