Maud Menten, a Physician and Biochemist
Maud Menten Canadian medical researcher Maud Menten (1879-1960) has been called the "grandmother of biochemistry," a "radical feminist 1920s flapper," and a "petite dynamo." Not only was she an author of Michaelis-Menten equation for enzyme kinetics (like the plot in indigo in my portrait), she invented the azo-dye coupling for alkaline phosphatase, the first example of enzyme histochemistry, still used in histochemistry imaging of tissues today (which inspired the histology background of the portrait), and she also performed the first electrophoretic separation of blood haemoglobin in 1944! Born in Port Lambton, Ontario, she studied at the University of Toronto, earning her bachelor's in 1904, and then graduated from medical school (M.B., bachelor's of medicine) in 1907. She published her first paper with Archibald Macallum, the Professor of Physiology at U of T (who went on to set up the National Research Council of Canada), on the distribution of chloride ions in nerve cells in 1906. She worked a year at the Rockefeller Institute in New York, where along with Simon Flexner, first director of the Institute, she co-authored a book on radium bromide and cancer, the first publication produced by the Institute - barely 10 years after Marie Curie had discovered radium. She completed the first of two fellowships at Western Reserve University (now Case Western Reserve University), then she earned a doctorate in medical research in 1911 at U of T. She was one of the first Canadian women to earn such an advanced medical degree. She then moved to Berlin (travelling by boat, unfazed by the recent sinking of the Titanic) to work with Leonor Michaelis. -
Maud Leonora Menten
Regulars Past Times A woman at the dawn of biochemistry Maud Leonora Menten Athel Cornish-Bowden Ask an average biochemist who was the first to realize that variant proteins could be detected by (Bioénergétique et Ingénierie electrophoresis and sedimentation, and had used this understanding to recognize different forms of des Protéines, CNRS and haemoglobin, the reply would probably refer to Linus Pauling and his work on sickle cell disease. Yet, Aix-Marseille Université, although this work was certainly important, that would be the wrong answer, because Maud Leonora France) and John Lagnado Menten, who sometimes seems to be remembered for one paper only, had this idea several years (Honorary Archivist, the before him, and used it to recognize the differences between foetal and adult haemoglobin1. She was Biochemical Society) unfortunate, however, in that her paper appeared in war time, and was eclipsed a few years later by a far more high-profile study2. In 2013 we celebrate two important centenaries not only of Director, and later the person who appointed Leonor the admission of women to the Biochemical Society (why Michaelis to his position there. With Flexner and James W. did it take so long?), but also of the publication of a paper Jobling, she wrote a book (the first monograph emanating by Maud Menten, who was one of the first women to leave from the Rockefeller Institute) on the effects of radium her mark in biochemistry, with a paper that is cited more bromide on tumours of animals, published in 1910 – often in the 21st Century than it was in the 20th. -
Metabolic Tracing of NAD Precursors Using Strategically Labelled Isotopes of NMN
A thesis submitted in fulfilment of the requirements for the degree of Doctor of Philosophy Metabolic tracing of NAD+ precursors using strategically labelled isotopes of NMN by Lynn-Jee Kim Supervisors Dr. Lindsay E.

NAD+ declines with biological ageing and in age-related diseases such as diabetes and strategies to restore intracellular NAD+ levels are emerging as a promising strategy to protect against metabolic dysfunction, treat age-related conditions and promote healthspan and longevity. One of the most effective ways to increase NAD+ is through pharmacological supplementation with NAD+ precursors such as nicotinamide mononucleotide (NMN) which can be orally delivered. Long term administration of NMN in mice mitigates age-related physiological decline and alleviates the pathophysiologies associated with a high fat diet- and age-induced diabetes. Despite such efforts, there are certain aspects of NMN metabolism that are poorly understood. In this thesis, the mechanisms involved in the utilisation and transport of orally administered NMN were investigated using strategically labelled isotopes of NMN and mass spectrometry. -

IUBMB Newsletter Issue 2.Pdf
IUBMB NEWS Issue 2 October 2016 President’s Message IUBMB aims to promote research and education in In This Issue Biochemistry and Molecular Biology. In this regard, over the President’s Message years we have channelled great efforts into the research aspects of our science. We now consider it timely to turn our Report on the 16th IUBMB attention to educational initiatives. Conference / Young To address this aim and in collaboration with FEBS, we are organising a conference on Education in Biochemistry and Molecular Biology, to be held in Scientists’ Program Rehovot (Israel) in September 2017. The conference seeks to provide a think-tank Tang Prize Foundation setting in which to draw up ideas to improve the current approach to teaching these subjects, and to generate a series of recommendations to be shared with Awardees / IUBMB Travel the educational community. In this regard, this conference will serve to propel the Fellowships changes that are required to bring education in biochemistry and molecular biology st at all levels into the 21 century. Another Way to Think About Another important aspect of education is to provide young scientists from Disease by Gregory Petsko developing countries the opportunity to attend international congresses and meetings. IUBMB is firmly committed to this endeavour and devotes significant Retrospective — financial resources to this end. Given that the number of applications from African countries is very low, I wish to encourage our young African colleagues to apply Osamu Hayaishi and benefit from IUBMB travel awards and Wood-Whelan fellowships. An Appreciation — IUBMB is also launching a new activity, namely Focused Meetings. -
