Porter was elected a fellow of the British Academy in , and was made an honorary fellow of the Royal College of Physicians and the Royal College of Psychiatrists. Starting with the publishing of his PhD thesis, as The Making of Geology in , Porter wrote or edited over books, an academic output that was, and is, considered remarkable.
https://senjouin-kikishiro.com/images/bevokinib/3841.php He is particularly notable for his work in the history of medicine, in pioneering an approach that focuses on patients rather than doctors. Despite his recognition in the history of medicine, he is quoted as saying, "I'm not really a medical historian. I'm a social historian and an 18th century man".
Published online Nov The seminar will comprise a mix of short lectures and class discussion. For example, the Ancient Egyptians also had a strong connection with animals which I hope to explore over the coming months in the UCL Petrie Museum, and the Grant Museum of Zoology also has a couple of gibbon skeletons hanging around. Wine has been with us since the dawn of civilization and has followed humans and agriculture along diverse migration paths Fig 1. He was known for the fact that he needed very little sleep.
In addition to the history of medicine and other sciences, he specialised in the social history of 18th-century Britain and the Enlightenment. He also wrote and lectured on the history of London.
With G. He also edited the journal History of Science for many years. In Roberta Bivins and John V. Several of the essays address Porter's work directly, and William F. Bynum appends a biographical sketch. Updated on May 20, Dodsley p. Lane p.

The engineered wine yeast strains described in this paper show the potential of novel yeast strain development to improve wine quality. Wine industries in most parts of the world have eschewed the use of GMOs in commercial winemaking, leaving most new-generation wine yeasts on the laboratory shelf, where they await more enlightened times. ML01, a transgenic wine yeast, has genes that enable it to perform malolactic fermentation MLF , a deacidifying secondary fermentation in which malic acid—present in grape juice—is decarboxylated to lactic acid. MLF is usually performed by the lactic acid bacterium Oenococcus oeni after alcoholic fermentation.
In addition, lacitic acid bacteria can produce a range of biogenic amines, which are associated with health risks Lonvaud-Funel, A wine yeast that completes both primary and secondary fermentations should therefore have great potential in the wine industry. The genetically modified wine yeast ML01 carries two foreign genes—the Schizosaccharomyces pombe malate transporter gene mae1 and the O.
This enables the host wine yeast to perform MLF, in parallel with alcoholic fermentation. The researchers went to great lengths to ensure the safety of ML The transgenes came from microorganisms found in wine, there were no antibiotic resistance genes or vector sequences carried by the yeast and transcriptome and proteome analysis showed no important differences in gene expression profiles between the genetically modified strain and its parent. This is largely owing to concerns about export markets that do not tolerate GMOs. In fact, wine industries in many countries have banned the use of GMOs in wine production, in order to avoid jeopardizing their exports.
Ethyl carbamate, a potential carcinogen, is the product of yeast-derived urea reacting with ethanol. It is usually produced at such low levels—if at all—that it is not a cause for concern, but it sometimes can make an appearance in some wine-producing regions. This is achieved by the action of an enzyme encoded by DUR1,2 , but this gene is repressed by nitrogen and therefore downregulated throughout much of wine fermentation. Interestingly, this genetically modified yeast is self or cis cloned; it carries no foreign DNA and therefore is not transgenic.
Nonetheless, because it was generated by using techniques that involved the manipulation of DNA in vitro , the regulations of many countries classify it as a GMO.
Again, to the best of our knowledge, this yeast is not being used in the industry. This might be because ethyl carbamate production is not a widespread problem, but it probably also reflects the influence of GMO bans and the reluctance of winemakers to risk losing market share in countries that harbour strong anti-GMO sentiment. Who knows what bottled masterpieces await us as we sculpt novel yeast strains in the laboratory using molecular, systems and synthetic biology. Winemaking, science and technology have interwoven histories and have grown together over the millennia, benefiting from each other.
Although science is an important part of an oenologist's training and scientific methods and equipment are routinely employed in the winery, winemakers are not scientists per se. As for many human endeavours, the Arts progress with developments in technology; think of the use of acrylic paint in the fine arts since its introduction in the s, or David Hockney's use of a Polaroid camera to create photocollages.
In the way that acrylic paint and photography have provided more options to artists, enabling them to broaden their horizons, yeast science and technology is adding to the winemaker's palette. The only real obstacle that we face is consumer acceptance of GMOs; we can only hope that rationality will eventually prevail. We hope that the series serves a delightful menu of interesting articles for our readers.
