Background Accumulating evidence points to an association between gut microbial
abnormalities and depression disorder. The microbiota-gut-brain axis is an emerging target …

Gastrointestinal (GI) comorbidities are common in individuals with mood and behavioral
dysfunction. Similarly, patients with GI problems more commonly suffer from co-morbid …

Background & Aims Mood disorders and constipation are often comorbid, yet their shared
etiologies have rarely been explored. The neurotransmitter serotonin (5-HT) regulates …

Background Relevant studies have shown that gut microbiome plays an important role in the
occurrence, development and treatment of major depressive disorder (MDD). Many studies …

Microbial conversion of dietary or drug substrates into small bioactive molecules represents
a regulatory mechanism by which the gut microbiota alters intestinal physiology. Here, we …

5-Hydroxytryptophan (5-HTP) has positive clinical effects on various neuropsychiatric and
metabiotic disorders, especially depression. Although it increases serotonin levels in the …

Background Existing evidence suggests that alterations in the gut microbiome are closely
associated with major depressive disorder (MDD). We aimed to reveal the causal …

Objective Increasing evidence has shown that the microbiota-gut-brain axis (MGB) is
involved in the mechanism of major depressive disorder (MDD). However, the relationship …

This work reports, for the first time, the association of electrochemical paper analytical
devices (ePADs) with batch injection analysis (BIA) systems. The novel 3D-printed BIA cell …

Here, a new and inexpensive electrochemical paper-based analytical device (ePAD)
containing a pencil-drawn three-electrode setup, in which the working electrode was …
