Vincent Marks, who has died aged 93, was a world professional in insulin and hypoglycaemia (low blood sugar). In 1985, his professional opinion helped to acquit Claus von Bülow of tried homicide, in a case that was dramatised within the movie Reversal of Fortune (1990).

On 21 December 1980, the American heiress Sunny von Bülow was found comatose in her toilet, and she or he remained in a persistent vegetative state till her dying in 2008. Her husband Claus, a Danish-born lawyer, was tried and located responsible of injecting her with insulin. On attraction in 1985, the defence confirmed there was no injection and, having scrutinised Sunny’s medical notes, Marks stated her collapse was more likely to have been triggered by alcohol-induced fasting hypoglycaemia. “Sunny,” he stated, “was the sufferer of pure sickness and her life-style.”

Marks’ achievements and curiosity in hypoglycaemia started within the late Nineteen Fifties when he created methods to detect low blood sugar and researched how the pancreas and glucose-management hormones work – very important data that underpins the fashionable remedy of diabetes.

From 1957 to 1962 he was a junior physician in chemical pathology on the Nationwide Hospital for Neurology and Neurosurgery in London. He noticed sufferers being identified with dementia and different neurological circumstances as a result of that they had confusion, anxiousness and panic assaults, however they could have had hypoglycaemia, which has the identical signs.

The prevailing check for low blood glucose required laboratory equipment and technical talent, so Marks developed an easier technique for medical doctors to make use of. It relied on the enzyme glucose oxidase, which made blood samples change color in response to the focus of glucose. It was a forerunner of the glucose strips extensively utilized in diabetes in the present day.

Marks labored with the South African researcher Ellis Samols to introduce a brand new method from the US known as insulin radioimmunoassay that might precisely measure the quantity of insulin within the blood. This opened up the entire subject of diabetes analysis. He additionally researched the connection between glucagon and insulin, two hormones produced within the pancreas that preserve blood glucose inside a traditional vary, and the position of a gut-derived hormone known as glucagon-like peptide-1 (GLP-1), which stimulates the pancreas to secrete insulin.

There he created and led a a lot bigger laboratory that grew to become the main centre for insulin testing within the UK. It was additionally there that he based and led the UK’s main MSc course in medical pathology.

Marks’ analysis included monitoring the extent of varied medication within the blood, together with lithium, and he developed an assay (a check) for the hormone melatonin and for insulin-like development factor-1 and a couple of (hormones that promote development of bones and tissues). He was serious about how blood sugar can rise and fall in response to completely different medicines, meals and alcohol, and in 1977 wrote a paper entitled Lunchtime Gin and Tonic: A Reason behind Reactive Hypoglycaemia.

He contributed to his specialty on the highest stage, turning into president of the Affiliation of Scientific Biochemists (1989-91) and vice chairman of the Royal School of Pathologists.

Marks was born in Harlesden, north-west London, the place his father, Lewis, and mom, Rose (nee Goldbaum), ran a pub. He had a youthful sister, Sheila, and an elder brother, John.

In 1995 Marks retired from his NHS and college jobs, however as an emeritus professor he continued to analysis and publish, reviewing one paper a day or so earlier than he died. He additionally remained engaged in medico-legal work, which he wrote about with the journalist Caroline Richmond in Insulin Murders (2007). In addition to his account of the trial to acquit Von Bülow, it tells of his half in securing the conviction of the nurse Beverly Allitt in 1993, who murdered 4 kids, killing two with insulin.

All through his life, Marks vocally supported a variety of causes. Disliking medical fraudsters, he was a founder member of HealthSense (initially HealthWatch); and he supported Dignity in Dying. At a neighborhood stage, he and his spouse campaigned to save lots of a neighborhood park from builders in Guildford.
