Probiotic Lactobacillus Plantarum 299v decreases kynurenine concentration and improves cognitive functions in patients with major depression: A double-blind, randomized, placebo controlled study
November 7, 2021
0
0
Main idea: Complex treatment of selective serotonin reuptake inhibitor with probiotic bacteria LP299v  improved cognitive performance and decreased inflammatory markers concentration in mood disorder patients. Decreased kynurenine concentration could contribute to the improvement of cognitive functions in the LP299v group compared to the placebo group. To our knowledge results of this study are the first […]

0
Abstract There has been an increased interest in understanding the therapeutic effect of gut-microbiota on health, particularly in mental health. Limited research into the connection between gut microbiota and mental health makes this study an important endeavor. Eligible participants completed a baseline survey before being assigned to a condition, which consisted of four probiotics conditions […]

Flavonoid-Rich Orange Juice Intake and Altered Gut Microbiome in Young Adults with Depressive Symptom: A Randomized Controlled Study
November 7, 2021
0
0
Main idea: There’s novel interventional evidence that alteration in the microbiome due to flavonoid treatment (in orange juice) is related to a potential improvement in depression in young adults. Abstract Depression is not just a general mental health problem but a serious medical illness that can worsen without treatment. The gut microbiome plays a major role […]

Effect of gut microbiota on depressive-like behaviors in mice is mediated by the endocannabinoid system
November 7, 2021
0
0
Main idea: Unpredictable chronic mild stress, diet, and gut microbiota generate a pathological feed-forward loop that contributes to despair behavior via the central endocannabinoid system. Abstract Depression is the leading cause of disability worldwide. Recent observations have revealed an association between mood disorders and alterations of the intestinal microbiota. In a mouse model of depression, mice […]

0
0
Main idea: gut microbiome regulates the work of gastrointestinal glial cells (part of the neural system) and plays a crucial part in mood disorders formation. Abstract The immune-inflammatory response is a fundamental component of the pathophysiology of major depressive disorder (MDD) Psychological stress and various inflammatory conditions contribute to such immune activation. The gastrointestinal tract, intestinal […]

Sex-related patterns of the gut-microbiota-brain axis in the neuropsychiatric conditions
November 7, 2021
0
0
Main idea: Although the clinical and preclinical studies are sparse and not very consistent, they suggest that sex differences in the gut microbiota may play an essential role in some neuropsychiatric conditions. Abstract Sex differences are often observed in psychiatric patients. The microbiota-gut-brain axis hypothesis arises to explain some aspects of the complex pathophysiology of neuropsychiatric […]

Relation between Mood and the Host-Microbiome Co-Metabolite 3-Indoxylsulfate: Results from the Observational Prospective NutriNet-Santé Study
November 7, 2021
0
0
Main idea: indole production by the gut microbiota may play a role in the onset of mood disorders in humans, urinary excretion of 3-indoxyl sulfate can be a marker for indole production. Abstract Gut microbiota metabolizes tryptophan(an essential amino acid) into indole, which can influence the brain and behavior. Some oxidized derivatives of indole have neuroactive […]

The Microbiome-Gut-Brain Axis and Resilience to Developing Anxiety or Depression under Stress
November 7, 2021
0
0
Main idea: gut microbiome can eliminate stress effects in mood disorders formation. Abstract Episodes of depression and anxiety commonly follow the experience of stress, however, not everyone who experiences stress develops a mood disorder. Stress alters the gut microbiota and plausibly this could contribute to stress-related changes in mood. Stress-resilience is influenced by several psychological and […]
