A pill to learn more about the gut microbiota

2019-11-15T11:45:36+01:0015 November 2019|The Science, Unusual|Comments Off on A pill to learn more about the gut microbiota

The gut microbiota, an organ difficult to define… The intestinal microbiota… What a vast organ! It consists of a very large number of microorganisms including one hundred thousand billion bacteria, the majority of which is housed in our intestines. Bacteria are ten times more numerous than our human cells. we are largely composed of bacteria, with whom we live in symbiosis. We develop our intestinal microbiota from birth. It becomes more complex with time until it becomes mature after 2-3 years. Very complex and diversified ecosystem, it is at the origin of many health essential functions  like the process of digestion [...]

S as synbiotics

2019-11-04T10:08:24+01:0001 November 2019|Glossary, S|Comments Off on S as synbiotics

Synbiotics means the alliance of probiotics and prebiotics. Synbiotics could be defined as : “could beneficially affect the host by improving survival and implantation of live microbial dietary supplements in the gastrointestinal flora, by selectively stimulating the growth or activating the catabolism of one or a limited number of health-promoting bacteria in the intestinal tract, and by improving the gastrointestinal tract's microbial balance” (Roberfroid, 2000). In other words, prebiotics will serve as fuel for probiotics in the product. They facilitate the growth of bacteria and allow them a better implantation in our intestines. The intake of probiotics will help to rebalance [...]

Reducing hangover thanks to a GMO probiotic drink

2019-10-04T12:56:31+01:0004 October 2019|That's your concern, Unusual|Comments Off on Reducing hangover thanks to a GMO probiotic drink

An American start-up, Z-biotics, has just launched a GMO probiotic drink on the market. Reminder: what is a GMO? It is a living genetically modified organism. In other words, the genetic heritage or DNA, has been modified by humans. The living organism then has new properties that it did not possess naturally. They are regulated and you can find them in: sweet corn as such, in ingredients or additives derived from corn, soya, rapeseed or beetroot among others, and more indirectly in animal feed GMOs bring controversy in the agricultural, scientific and economic areas. Indeed, there are uncertainties about the use [...]

If sports performance depended on an intestinal bacterium?

2019-09-06T12:55:44+01:0006 September 2019|That's your concern, The Science|Comments Off on If sports performance depended on an intestinal bacterium?

The holidays are over and it is time to go back to school or work. It is also time for good resolutions! And that can go through the resumption of physical activity. But, as you can imagine, we are not all equal: some are good, some are not...  Physical performance would be due to a bacterium And if the physical abilities were due to the microbiota composition? This is what are reported the team of Joslin Diabetes researchers after analyzing Boston runners in 2015. Scientists recovered fecal samples from athletes over a 2-week period: from one week before until one week [...]

From clothes to probiotics, the new generation of probiotics?

2019-08-22T14:47:15+01:0023 August 2019|Skin, Unusual|Comments Off on From clothes to probiotics, the new generation of probiotics?

Rebalance the skin microbiota by wearing probiotic clothes? It is now almost possible! Currently, it is still in the concept state. An idea from science The science shows that the cutaneous microbiota serves as a barrier against certain microorganisms, allergens and other toxins by limiting the infectious and pathological impact. Acne, eczema, rosacea, psoriasis… Skin conditions potentially caused or exacerbated by an imbalance between good and bad bacteria present on our skin. The hypothesis: the hygienist theory. In other words, inadvertent washing and disinfection causing dysbiosis. In addition, the cosmetic composition of used products and the wearing of certain clothes can [...]

Book – « Follow your gut »

2019-08-09T09:33:12+01:0009 August 2019|That's your concern, The Science|Comments Off on Book – « Follow your gut »

(Freepik) Rob Knight, a researcher from University of California. He is a recognized scientist in the field of gut microbiota.  He has written the book named “Follow your gut” in collaboration with the journalist Brendan Buhler. This book is based on his TED talk (2014) “How our microbes make us who we are”. It gives a general vision of the gut microbiota and current knowledge on it. The author-researcher begins his book on a basic concept. He explains to us that the human being is not alone in his body. Indeed, it lives in symbiosis with innumerable microorganisms having [...]

Modify the skin microbiota to repel mosquitoes, is it possible?

2019-08-09T10:44:47+01:0026 July 2019|Skin, Unusual|Comments Off on Modify the skin microbiota to repel mosquitoes, is it possible?

In any case, this is what the US army wants to do in order to protect their soldiers. Darpa (Defense Advanced Research Projects Agency) has launched a new program, named ReVector, to find ways to reduce or even eliminate the risk of transmitting diseases caused by mosquitoes. Mosquitoes, these vectors of diseases Indeed, these insects (including Aedes, Anopheles and Culex) are vectors of potentially lethal diseases such as malaria, dengue fever, the Murray Valley or Japanese encephalitis. These pathologies represent a great threat for troops deployed abroad. A new approach to repel mosquitoes: modification of the cutaneous microbiota Why not just [...]

Can the ocean modify our microbiota?

2019-08-09T10:48:16+01:0012 July 2019|Skin, That's your concern, The Science|Comments Off on Can the ocean modify our microbiota?

Summer is finally here! You spend your free time enjoying the sun and maybe even going to the beach. But do you know that swimming in the ocean can alter the skin microbiota? And in addition, can increase the infection risk? A team of researchers presented clinical results suggesting some interactions between our skin and the ocean at the annual meeting of the American Society for Microbiology. This clinical trial was motivated by previous studies showing a correlation between swimming at sea, water quality and the infection risk. Indeed, microbiota changes can cause skin, gastrointestinal, or ENT infections including respiratory or [...]
