Scientists have made new achievements in the field of brain and bowel axis research!

This study has significant implications for public health, and researchers say excess sugar intake is often associated with obesity-related diseases, such as diabetes, that affect the health of more than 500 million people worldwide;
researcher Hwei-Ee Tan says that when we drink sugar-free sodas or use sweeteners in coffee, they may taste very similar, but our brains can tell the difference; special intestinal-brain circuits that respond to sugar may provide ideas for the development of new sweeteners.

once the worm is full, or the food (in this case, bacteria) runs out, it will start moving again.
now, in a new study, researchers from the Massachusetts Institute of Technology in the United States have revealed in more detail how caenorhabitis elegans' digestive tracts send signals to the brain when they stay in food-rich places.
they found that a class of neurons present in the nematode's intestines were specifically designed to monitor when nematodes ingest bacteria;
also found new ion channels for detecting bacteria in this particular neuron, the study was published in the journal Cell.
researchers already know that serotonin release promotes the slowing down of the worm in order to eat large amounts of food, but they don't know what triggers serotonin release.
To find out, they decided to study a intestinal neuron called neurosecretory-motor neuron (NSM), which produces serotonin, which is located on the inner wall of the nematode's digestive organs.
6 (Xinhua) -- Scientists have found that skin health is affected by the intestinal-brain-skin axis And studies have shown that skin diseases and mental illness are co-pathological, and basic and clinical studies have found that psychosocial factors have an effect on the incidence of skin diseases.
such as psychological stress can aggravate a variety of skin diseases, especially endemoric dermatitis, psoriasis, seborrhed eczema, nodule itch, flat palate, chronic urticaria, baldness and itching.
addition, gut microorganisms can affect the occurrence of skin diseases, and mental state and intestinal microbial condition can reflect the health of the skin.
, skin conditions can also be used as a reference for the assessment of mental state and gut microbial condition.
, however, the relationship between skin diseases, mental illness and gut microbes needs further study.
The Jin Feng Research Group of the Mental Health Key Laboratory of the Institute of Psychology of the Chinese Academy of Sciences found that people with both mental and mental illness had a very high rate of skin problems at the same time, and by testing the composition of gut microorganisms, they found that the composition of their gut symbicisms was significantly different from that of healthy people.
interventions against gut microbes were implemented, the patient's mental state and skin symptoms improved as the intestinal symbic microbes recovered.
scientists call the association between intestinal status, gut microbes, and mental illness and skin diseases the intestinal-brain-skin axis, or gut-brain-skin axis.
7 Science Sub-Journal: Amazing Discovery! In a study published in the international journal Science Translational Medicine, researchers from McMaster University found that bacteria in the gut may be able to affect the gut and behavioral symptoms of patients with irritable bowel syndrome (IBS), a study that may provide new insights into the symptoms of the gut and behavior of patients with irritable bowel syndrome (IBS).
Intestinal irritable syndrome is a common gastrointestinal disease, which affects the body's large intestine tissue, and patients will also suffer abdominal pain and changes in bowel habits, such as diarrhea and constipation, usually accompanied by chronic anxiety and depression, the current treatment is intended to improve the patient's symptoms, but the cause of the patient is not clear, so the efficacy of these treatments is very limited.
In this study, researchers hope that the study will provide further clarification as to whether fecal microorganisms in the body of IBS patients with diarrhea can affect the gut and brain function of the receptor mouse body, and using fecal transplantation, the researchers transferred the microbiome of IBS patients (anxiety or non-anxiety patients) to the sterile mouse body, and then found that mice receiving microorganisms in the body of healthy individuals slowly showed changes in intestinal function and behavior compared to mice receiving healthy individual microorganisms.
