Book – Jamais seul

2019-12-13T10:40:20+01:0013 December 2019|That's your concern|Comments Off on Book – Jamais seul

The Eukaryotes, to which we belong, are never alone: “they have acquired their main energetic metabolisms of bacteria which they have packaged into their cells and which have become hereditary”. This quote from the excellent book “Jamais seul” written by Marc-André Selosse, reflects quite well the author’s idea: organisms resulting from the evolution of living world have always dealt with bacteria. The author therefore offers us a vision of the original life and sometimes confusing due to the systematic presence of microorganisms in biological processes. A book that teaches us perfectly the symbiosis notion, described through many examples in the unicellular, [...]

Contact lenses: a device that modifies the ocular microbiota

2019-11-29T09:37:38+01:0029 November 2019|That's your concern, The Science|Comments Off on Contact lenses: a device that modifies the ocular microbiota

Contact lenses are very useful in everyday life for many people. Indeed, they allow invisible vision correction. Placed directly on the eye cornea, contact lenses offer an excellent field of view. But did you know that the eye is harboring its own microbiota? A bacterial community that provides protection against possible harmful microorganisms? Now, you do. This ecosystem which is present on the eyes’ surface, could be altered when it comes into contact with contact lenses. Wearing lenses changes the ocular microbiota… Lens wearers have a bacteria proportion in the eyes identical to those found on the skin. This outcome results [...]

Reducing hangover thanks to a GMO probiotic drink

2019-10-04T12:56:31+02:0004 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+02:0006 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 [...]

Book – « Follow your gut »

2019-08-09T09:33:12+02:0009 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 [...]

Can the ocean modify our microbiota?

2019-08-09T10:48:16+02:0012 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 [...]

Titanium dioxide, enemy of the intestinal microbiota?

2019-08-09T10:45:58+02:0019 June 2019|That's your concern, The Science|Comments Off on Titanium dioxide, enemy of the intestinal microbiota?

Titanium dioxide TiO2 or E171, is a nanoparticulate additive found in certain foodstuffs, including food supplements, as white opacifying and colour. This additive is present in chewing gums, sweets, industrial pastries, toothpastes, sunscreens, caps… Titanium dioxide is currently a very controversial ingredient. Its use should be banned in France by January 1st 2020. Indeed, it would present a risk for the consumer safety. One of the consequences of its ingestion would be an alteration of the intestinal microbiota. E171 has a deleterious effect on the bacterial activity and the intestinal ecosystem balance (dysbiosis), potentially favoring inflammatory diseases or colorectal cancer in [...]

Probiotics, true allies of intimate comfort

2019-08-09T11:00:52+02:0019 April 2019|That's your concern, Women|Comments Off on Probiotics, true allies of intimate comfort

A balanced vaginal microbiota is a crucial component of women’s health warranting particular attention in order to limit infections causing uncomfortable symptoms such as itching, irritation, etc… What is the vaginal microbiota? Discovered by German gynaecologist Albert Döderlein, the vaginal microbiota is dominated by lactic bacteria called Lactobacilli (95%). But it also contains numerous other microorganisms present in lower quantities. Lactobacilli guarantee a healthy, balanced vaginal flora. They form a genuine defence system against infections, via the formation of a protective biofilm on the vaginal mucosa, preventing the proliferation of pathogenic microorganisms. To achieve this, they employ several mechanisms: Stimulation of immune system.
 Competition with other microorganisms for nutrients and adhesion sites on the vaginal epithelium.
 Maintenance [...]
