An artificial bronchus was successfully grafted to a patient in France 78 years who suffered from lung cancer, a world first that has prevented the complete ablation of the body, today announced the management of public hospitals in Paris.
The operation, conducted on October 28, 2009 by a team of Bobbing Avicenna hospital on the outskirts of Paris, “led not only to remove the cancerous lesion with important safety margins but also prevent the planned complete ablation of lung gesture that implies a very high risk of postoperative mortality, “he said in a statement.
The patient “is doing very well,” said Professor Emmanuel Marti nod, the thorax surgeon who performed the operation vascularity.
Artificial bronchus was performed with a biological tissue (aortic) reinforced by a metal structure inside (stent). Was kept cold in a tissue bank. This process gives the advantage of not requiring anti-rejection drugs, contraindicated in cancer.
The experimental work that enabled the world premiere was performed in the laboratory biosurgical Research headed by Professor Alain Carpenter, was noted.
“Our commitment is based on 10 years of research,” said Professor Marti nod He estimated, however, that “had to be careful” in waiting.
A study of 20 to 30 patients to be launched this month to confirm the first result, which will be published in The Annals of Thoracic Surgery.
A groundbreaking study by researchers from Argentina and Portuguese – published in the Journal of Food Protection, “says a path that could make the cheese industry waste into useful products for the food industry.
“The effluent from cheese factories, as is the case of whey, often pollutants, unless they are given a utility,” said Dr. Graciela Garrote, one of the authors of the study who serves as researcher at the Center for Research and Development in Food Cry technology (CIDCA) of the Universidad National de La Plata (UNLP) – CONICET.
The work consisted of whey fermented with kefir grains (a mixture of bacteria and yeast). It was noted that the product obtained had a high antibacterial activity. For example, pathogens such as Salmonella and Escherichia coli, which tend to contaminate food, completely lost their viability when exposed to this new product.
Kefir grains have a look similar to cauliflower flowers are composed of bacteria and yeast robotic (microorganisms that have beneficial effects on the body), proteins and polysaccharides. These granules fermented whey and lactic acid is produced, among other metabolites, which is the main inhibitor of contaminating bacteria.
The composite developed has several advantages: it recycles waste industry has the ability to eliminate pathogens and pollutants and also potentially robotic microorganisms are added, i.e. beneficial to human health. Among the effects associated with its use are immune stimulation, inhibition of tumor growth, antioxidant capacity and reducing cholesterol levels.
For Dr. Garrote, and produces a novel, but still need further scientific studies. “We believe that whey fermented with kefir grains can be used as a robotic in humans or animal studies are completed in vivo evaluation”, concludes the scientist who with a team of colleagues in 2009 received a first prize of Marcos in recognition of this line of research that points to the comprehensive use of dairy effluent to the development and preservation of robotics.
