Dogs aid breast cancer research
Breast carcinoma has long been known to share similarities in dogs and humans.
New similarities found in mammary tumours 

Scientists have discovered new similarities between mammary tumours in dogs and breast carcinomas in humans.

Using archived samples of mammary tumours from dogs, researchers at the University of Zurich found that some cells in the vicinity of the tumour behave in the same way as corresponding cells in humans.

In the development of tumours and the progression of carcinomas, both the characteristics of cancer cells and the cells surrounding the tumour are important. In humans, many tumours are able to reprogram healthy cells around the the tumour so that they support the growth of cancerous cells.

This mechanism plays a major role in human breast carcinoma, but until now it was not known whether this occurs in dogs; despite the fact that breast carcinoma has long been known to share similarities in dogs and humans.

When Zurich scientists analysed the surrounding tissue of canine mammary tumours they found that the healthy tissue around the tumour produced substances that promote the growth of tumours.

Enni Markkanen, of the University of Zurich’s Vetsuisse Faculty, explained: “Simply speaking, the tumour enslaves its environment: it forces the surrounding cells to work to its benefit.”

Researchers say this mechanism works in the same way in dogs and in humans, meaning tumour tissue from dogs is much better suited to research on breast carcinoma than tissue from rats on cells cultivated in the laboratory.

Markkanen added: “Importantly, however, we don’t view our dog patients as test subjects for cancer research. But they can help us to better understand breast carcinoma in both dogs and humans and fight it more effectively.”

Vets to run marathon for World Animal Protection

News Story 1
 Two recently graduated veterinary surgeons will be running the London Marathon in April to raise money for the charity World Animal Protection.

Alex Bartlett and Maeve O'Neill plan to run the race together if they are given the same start times.

Dr O'Neill said: "You're always limited in what you can do to help animals, so it is nice to raise money for a charity that helps animals around the world."

Dr Bartlett added: "I have never run a marathon before and am excited to run my first one for such a good cause!"

Both Dr Bartlett and Dr O'Neill have fundraising pages online.

BSAVA releases new Guide to Procedures

The British Small Animal Veterinary Association (BSAVA) has published a new edition of its Guide to Procedures for Small Animal Practice.

It has added four new procedures; cystostomy tube placement, endotracheal intubation, point-of-care ultrasound and wet-to-dry dressings.

BSAVA says that it is an essential step-by-step guide to diagnostic and therapeutic procedures performed in practice. The textbook includes new images and illustrations, as well as high-definition videos for use prior to procedures.

Nick Bexfield and Julia Riggs, editors of the new edition, said: "We have built upon the success of the previous editions by responding to the feedback received from the BSAVA readership, and hope this new guide helps to further increase the confidence and accuracy with which these procedures are performed."

Print copies are available in the BSAVA store, with a digital version in the BSAVA library.
