N,N-dimethyltryptamine compound found in the hallucinogenic tea ayahuasca, regulates adult neurogenesis in vitro and in vivo

Ayahuasca, Gut Dysbiosis, Gut Microbiota, Gut Permeability / Leaky Gut, Gut-Brain axis, Uncategorized /

N,N-dimethyltryptamine (DMT) is a component of the ayahuasca brew traditionally used for ritual and therapeutic purposes across several South American countries. Here, we have examined, in vitro and vivo, the potential neurogenic effect of DMT. Our results demonstrate that DMT administration activates the main adult neurogenic niche, the subgranular zone of the dentate gyrus of […]

Good bacteria, oxidative stress and neurological disorders: Possible therapeutical considerations

Gut Dysbiosis, Gut Microbiota, Probiotics, Prebiotics and Symbiotics /

Although oxidative agents such as free radicals can fight pathogens, an imbalance of oxidants to anti-oxidant activity can lead to harmful effects in our body known as oxidative stress. Various cellular organelles produce oxidative agents as well as anti-oxidants. The main oxidative stressors are classified under the free radical species; reactive oxygen species and reactive

Consumption of a novel prebiotic mixture rapidly impacted the intestinal microbiota (10 days), reduced the abundance of pro-inflammatory bacteria and promoted the growth of beneficial SCFA-producing bacteria. In addition, prebiotic consumption increased plasma SCFA levels, and improved markers of intestinal barrier integrity and brain health. This proof-of-concept study provides evidence for the importance of intestinal

Acupuncture inhibits neuroinflammation and gut microbial dysbiosis in a mouse model of Parkinson’s disease

Gut Dysbiosis, Gut Microbiota, Gut Permeability / Leaky Gut, Parkinson's Disease, Pre-PD /

Growing evidences show that gut microbiota is associated with the pathogenesis of Parkinson’s disease (PD) and the gut-brain axis can be promising target for the development of the therapeutic strategies for PD. Acupuncture has been used to improve brain functions and inflammation in neurological disorders such as PD, and to recover the gastrointestinal dysfunctions in

Mucin modifies microbial composition and improves metabolic
functional potential of a synthetic gut microbial ecosystem

Gut Dysbiosis, Parkinson's Disease, Pre-PD, Probiotics, Prebiotics and Symbiotics /

Microbial dysbiosis in the gut is associated withhuman diseases, and variations in mucus alter gut microbiota.Therefore, we explored the effects of mucin on the gut microbiotausing a community of 19 synthetic gut microbial species. Cultivationof these species in modified Gifu anaerobic medium (GAM)supplemented with mucin before synthetic community assemblyfacilitated substantial growth of the Bacteroides, Akkermansia,and

Parkinson’s Disease: A Prionopathy?

A-Synuclein, Biomarkers, Gut Dysbiosis, Gut Microbiota, Gut Permeability / Leaky Gut, Gut-Brain axis /

The principal pathogenic event in Parkinson’s disease is characterized by the conformational change of α-synuclein, which form pathological aggregates of misfolded proteins, and then accumulate in intraneuronal inclusions causing dopaminergic neuronal loss in specific brain regions. Over the last few years, a revolutionary theory has correlated Parkinson’s disease and other neurological disorders with a shared

Aging Microbiota-Gut-Brain Axis in Stroke Risk
and Outcome

Gut Dysbiosis, Gut Microbiota, Gut-Brain axis, Probiotics, Prebiotics and Symbiotics, Stroke /

The microbiota-gut-brain-axis (MGBA) is a bidirectional communication network between gut microbes and theirhost. Many environmental and host-related factors affect the gut microbiota. Dysbiosis is defined as compositional andfunctional alterations of the gut microbiota that contribute to the pathogenesis, progression and treatment responses todisease. Dysbiosis occurs when perturbations of microbiota composition and function exceed the ability

Fermented brown rice beverage distinctively modulates the gut microbiota in Okinawans with Metabolic Syndrome: a randomized controlled trial

Accumulating evidence to date suggests that brown rice is superior to white rice in regards to its beneficial impact on a number of risk factors of the metabolic syndrome (MetS). However, little is known about the influence of fermented brown rice beverage on the gut microbiota in humans. We therefore hypothesized that its impact would

The gut microbiome is associated with diverse diseases1,2,3, but a universal signature of a healthy or unhealthy microbiome has not been identified, and there is a need to understand how genetics, exposome, lifestyle and diet shape the microbiome in health and disease. Here we profiled bacterial composition, function, antibiotic resistance and virulence factors in the

Emerging multi-drug resistant pathogens are the main driving force behind the efforts to find analternative treatment approach such as probiotics. Probiotics are considered living drugs that can reduce theconsumption of conventional antibiotics and improve human and animal health. Particularly, bacterial originprobiotics became increasingly popular during the last two decades as a result of the continuously
