Je ne suis pas un ultra connecté, mais j'ai toujours vu dans les nouvelles technologies un futur passionnant et sans limite.

J'ai une tablette sur laquelle j'ai regardé ce qu'il y avait sur le médical et j'y ai trouvé plusieurs applications sur le corps humain notamment. Mais soit trop compliquées, soit trop chère. J'ai arrêté de chercher et c'est par hasard que je suis tombé sur cette application : TINYBOP. C'est une très jolie application ludique qui, sans donner trop d'informations, permet aux enfants d'apprendre le fonctionnement du corps humain tout en s'amusant.

C'est un accompagnement que l'adulte peut utiliser aussi pour demander à son enfant ce qu'il ressent. Il y a une vision du corps dans sa globalité et des détails tels que les dents, l'estomac ou les articulations principales.C'est très important de pouvoir expliquer et comprendre le corps humain.

Illustration by Serge Bloch Nearly a year has passed since Rebecca Knickmeyer first met the participants in her latest study on brain development. Knickmeyer, a neuroscientist at the University of North Carolina School of Medicine in Chapel Hill, expects to see how 30 newborns have grown into crawling, inquisitive one-year-olds, using a battery of behavioural and temperament tests. In one test, a child's mother might disappear from the testing suite and then reappear with a stranger. Another ratchets up the weirdness with some Halloween masks. Then, if all goes well, the kids should nap peacefully as a noisy magnetic resonance imaging machine scans their brains. “We try to be prepared for everything,” Knickmeyer says. Knickmeyer is excited to see something else from the children — their faecal microbiota, the array of bacteria, viruses and other microbes that inhabit their guts. The project comes at a crucial juncture. In humans, the data are more limited.

Manipulating the Microbiome: diet, environment, and genetics. Le microbiote intestinal : un organe à part entière - PARLONS SCIENCES. Malgré la cohabitation avec ces milliards de bactéries à l’âge adulte, le nouveau né est stérile à la naissance. Le premier contact avec des bactéries s’effectue lors de l’accouchement. La composition du microbiote varie fortement dans les premiers mois de la vie au gré du passage des bactéries dans notre tube digestif. La diversité des bactéries présentes dans notre tube digestif augmente progressivement et c’est vers l’âge de deux ans que le microbiote se stabilise pour être fonctionnellement proche de celui retrouvé à l’âge adulte. Cette stabilité est néanmoins fragile car le microbiote est soumis à de nombreux facteurs pouvant le modifier tels qu’un régime alimentaire trop gras ou une prise fréquente d’antibiotiques.

La répartition des bactéries le long du tube digestif n’est pas homogène. En pratique, il est difficilement envisageable de récupérer les bactéries intestinales directement dans le côlon car cette procédure est invasive pour le patient et nécessite une anesthésie. 1. Microbiota – the forgotten organ. Back to overview Today, the idea that gut bacteria affects a person’s health is not new. Most of us know that these microbes influence digestion, allergies, and metabolism. New books explaining which diet will lead to optimum bacterial health are published regularly and most of us have at least heard one time about its importance for our health.

Recent studies even suggest that one of the benefits of the Mediterranean diet, recognized as one of the healthiest in the world might come from its favorable impact on gut flora (De Filippis 2015). Microbiota – the forgotten organThe term microbiota basically refers to all the bacteria living in our digestive system and consists of a complex community of microorganisms. Gut flora also has a so-called "barrier effect" which prevents other microorganisms to develop in the host. Gut flora – the never ending storyGut flora is formed over time and from the day you're born. The gut flora as a forgotten organ. Gout diet: Fruit and vegetables could cure painful form of arthritis | Health. Eating plenty of fruit and vegetables can reduce the risk of agonising gout attacks, as it can affect gut bacteria, experts have said. They said following a high fibre diet combats the razor sharp crystals that form in and around the joints and under the skin. Gout is caused by too much uric acid in the bloodstream, which causes urate crystals to start to form in and around the joints and under the skin.

The condition affects about one in 100 people, with men two to three times more likely to be affected than women. However the condition can sometimes affect post-menopausal women. Gout is commonly associated with drinking too much. The condition is a metabolic disease in which crystals of uric acid - a waste product in the blood - form in the body's tissues or joints. However research has shown the action of gut microorganisms, influenced by different types of food, can affect inflammation in the body.

He said future work could lead to practical treatments for gout and other diseases. Coming of age: ten years of next-generation sequencing technologies : Nature Reviews Genetics. Since the completion of the human genome project in 2003, extraordinary progress has been made in genome sequencing technologies, which has led to a decreased cost per megabase and an increase in the number and diversity of sequenced genomes. An astonishing complexity of genome architecture has been revealed, bringing these sequencing technologies to even greater advancements. Some approaches maximize the number of bases sequenced in the least amount of time, generating a wealth of data that can be used to understand increasingly complex phenotypes.

Alternatively, other approaches now aim to sequence longer contiguous pieces of DNA, which are essential for resolving structurally complex regions. These and other strategies are providing researchers and clinicians a variety of tools to probe genomes in greater depth, leading to an enhanced understanding of how genome sequence variants underlie phenotype and disease.

Could our gut micriobiome hold a key to treating or preventing autism? Microbiome may be next big frontier in medicine. The GLP aggregated and excerpted this blog/article to reflect the diversity of news, opinion and analysis. The human gut microbiome — which includes the community of trillions of bacteria living within our intestines — has been called one of the next big frontiers in medicine. In recent years, a growing body of research has shown that the bacteria in our gut exert a powerful influence on our immune and endocrine systems, brain health, mood and cognitive function, and other key biological processes. We know that the balance of good and bad bacteria in the gut can keep us healthy — or can contribute to disease.

Now, the next step for this exciting medical frontier is learning how to leverage the power of the microbiome to treat disease. In new research, biologists and medical engineers at the Massachusetts Institute of Technology are doing just that by reprogramming gut bacteria to act as “living therapeutics” that can correct the metabolic dysfunctions underlying certain ailments.

January High Five – Writing and Re-writing History – Altmetric. Welcome to a new year of the Altmetric High Five! On a monthly basis, my High Five posts examine a selection of the most popular research outputs Altmetric has seen attention for that month. This month’s theme is changing history. The top scientific papers this month according to Altmetric.com all have big implications for our understanding of human, and celestial, history. Pluto may no longer be a planet, but another “planet nine” may lurk beyond it. Pluto in false color. Image credit: NASA’s Marshall Space Flight Center. Paper #1. Our top High Five paper this month is titled “Evidence for a distant giant planet in the solar system,” published in The Astronomical Journal on January 20. Did scientists just discover Planet Nine of our solar system?! Not quite, or at least not yet. The study was picked up by over 300 news outlets and dozens of blogs.

There might be a ninth planet in the solar system after all, and it is not Pluto. “[H]ow did we not observe this planet before?” More reading: Sorry, it turns out you are human after all | MicrobiologyBytes. Sorry, it turns out you are human after all It’s often said that the bacteria and other microbes in our body outnumber our own cells by about ten to one. But that’s a myth that should be forgotten according to a new paper – the ratio between resident microbes and human cells is more likely to be one-to-one.

The myth arises from a rough estimate made in 1972 which has persisted ever since. Of course, this only applies to cells – the number of viruses in your body vastly outnumber all the cells. Revised estimates for the number of human and bacteria cells in the body. (2016) bioRxiv We critically revisit the ″common knowledge″ that bacteria outnumber human cells by a ratio of at least 10:1 in the human body. Like this: Like Loading...

Voilà qui est un peu décevant. Du moins, débobinant pour un journaliste toujours assoiffé de manchettes grosses comme ça, croustillantes extra-sauce. Parce que, vous voyez, dans la recherche infinie de sensation, ça faisait toujours un bel effet d’écrire que le corps humain s’accommode tellement bien des bactéries, et qu’il en a en fait tellement besoin, qu’il compte dix bactéries pour chaque cellule humaine. En majuscule, ça frappait encore plus fort, regardez-moi ça : POUR CHACUNE DE VOS CELLULES, VOUS TRANSPORTEZ DIX BACTÉRIES ! Pour faire chic et savant, on pouvait même dire que le corps abrite 101 fois plus de bactéries que de cellules. Mais ces beaux jours, que dis-je, cet âge d’or est désormais révolu.

Alors l’inévitable a fini par se produire : quand on court après le trouble, on parvient invariablement à le rattraper et un trio de chercheurs d’Israël et du Canada a fait paraître ces derniers jours un nouvel estimé franchement déprimant. (Soupir.) Microbiome remains malleable after birth. The GLP aggregated and excerpted this blog/article to reflect the diversity of news, opinion and analysis. Trillions of bacteria – and other tiny single-celled organisms, such as archaea and protozoa – live in our bodies, largely in our gut. They’re estimated to outnumber the actual cells of “our” bodies. This ecosystem of tiny creatures we carry around with us is thought to have profound effects on our health. The Human Microbiome Project says that the makeup of an animal’s microbiome has an impact on its immune systems, heart health, and behaviour, among other things.

It’s thought that early life events, notably birth and breastfeeding, might affect our microbiomes. People who are born by caesarean section seem to be slightly more at risk of obesity, asthma, and some immune conditions. Now a new study has found that the effects of these early events don’t last as long as previously thought.
