Physical health has a direct relationship with digestive function. Any abnormalities in the link may cause malnutrition, endocrine disorders, and the decline of organ functions. Obestatin, a biologically active peptide, is encoded by the ghrelin gene. Most studies suggest that obestatin is a pleiotropic peptide, which acts by suppressing the motility of the gastrointestinal tract, regulating the secretion of insulin, reducing inflammation and apoptosis, and promoting proliferation. These characteristics suggest that obestatin may represent an efficient way to prevent the occurrence and development of some digestive diseases...

Our emotional state can have many consequences on our somatic health and well-being. Negative emotions such as anxiety play a major role in gut functioning due to the bidirectional communications between gut and brain, namely, the brain-gut axis. The irritable bowel syndrome (IBS), characterized by an unusual visceral hypersensitivity, is the most common disorder encountered by gastroenterologists. Among the main symptoms, the presence of current or recurrent abdominal pain or discomfort associated with bloating and altered bowel habits characterizes this syndrome that could strongly alter the quality of life...

Video capsule endoscopy (VCE) has been applied in the last 15 years in an increasing field of applications. Although many contraindications have been put into perspective, some precautions still have to be considered. Known stenosis of the gastrointestinal tract is a clear contraindication for VCE unless surgery is already scheduled or at least has been considered as an optional treatment modality. In patients with a higher incidence of stenosis, as in an established diagnosis of Crohn's disease, clinical signs of obstruction, prior radiation or surgical small bowel resection, a preceding test with the self-dissolving patency capsule can override this contraindication...

Gastrointestinal sphincters play a vital role in gut function and motility by separating the gut into functional segments. Traditionally, function of sphincters including the esophagogastric junction is studied using endoscopy and manometry. However, due to its dynamic biomechanical properties, data on distensibility and compliance may provide a more accurate representation of the sphincter function. The endolumenal functional lumen imaging probe (EndoFLIP) system uses a multi-detector impedance planimetry system to provide data on tissue distensibility and geometric changes in the sphincter as measured through resistance to volumetric distention with real-time images...

Balneotherapy or spa therapy is usually known for different application forms of medicinal waters and its effects on the human body. Our purpose is to demonstrate the effect of balneotherapy on gastrointestinal motility. A total of 35 patients who were treated for osteoarthritis with balneotherapy from November 2013 through March 2015 at our hospital had a consultation at the general surgery for constipation and defecation disorders. Patients followed by constipation scores, short-form health survey (SF-12), and a colonic transit time (CTT) study before and after balneotherapy were included in this study, and the data of the patients were analyzed retrospectively...

AIM: Functional gastrointestinal disorders affect females more often. Changes in colonic motility may be etiological co-factors for the clinical symptoms. The aim of the present study was to analyze the influence of gonadal hormones on colonic contractile activity. METHODS: In vitro measurements of colonic contractile activity in longitudinal smooth muscle strips of female and male Lewis rats were performed in an organ chamber experiment set-up. After administration of a gonadal hormone (estrogen (EST), progesterone (PROG) and testosterone (TEST)) or ethanol (ETH) solution as control, stimulation with acetylcholine (ACh) or inhibition with norepinephrine (NE) was performed...

Defecation disorders is a common gastrointestinal disease characterized by slow colonic transit and/or paradoxical anal contraction. Gastrointestinal motility test plays an important role in the diagnosis, classification and treatment of defecation disorders. Anorectal manometry (ARM) provides comprehensive information about rectal and anal sphincter function, including resting anal sphincter pressure, squeeze anal sphincter pressure, the rectal and anal sphincter pressure changes during an attempted defecation, rectal sensory testing, rectoanal inhibitory reflex and rectal compliance...

Postoperative ileus, which develops after each abdominal surgical procedure, is an iatrogenic disorder characterized by a transient inhibition of gastrointestinal motility. Its pathophysiology is complex involving pharmacological (opioids, anesthetics), neural, and immune-mediated mechanisms. The early neural phase, triggered by activation of afferent nerves during the surgical procedure, is short lasting compared to the later inflammatory phase. The latter starts after 3-6 h and lasts several days, making it a more interesting target for treatment...

We developed a hybrid strain sensor by combining mechanoluminescent ZnS:Cu/rhodamine/SiO2/PDMS composites and piezoresistive CNT/PDMS for qualitative and quantitative analysis of onsite strain. The former guarantees a qualitative onsite measure of strain with red-light emission via mechanoluminescence (ML) and the latter takes part in accurate quantification of strain through the change in electrical resistance. The PDMS matrix enabled a strain sensing in a wider range of strain, spanning up to several hundred percent in comparison to the conventional rigid matrix composites and ceramic-based ML sensors...

The ancient and ubiquitous monoamine signalling molecules serotonin, dopamine, norepinephrine, and epinephrine are involved in multiple physiological functions. The aromatic amino acid hydroxylases tyrosine hydroxylase (TH), tryptophan hydroxylase 1 (TPH1), and tryptophan hydroxylase 2 (TPH2) catalyse the rate-limiting steps in the biosynthesis of these monoamines. Genetic variants of TH, TPH1, and TPH2 genes are associated with neuropsychiatric disorders. The interest in these enzymes as therapeutic targets is increasing as new roles of these monoamines have been discovered, not only in brain function and disease, but also in development, cardiovascular function, energy and bone homeostasis, gastrointestinal motility, hemostasis, and liver function...

Kisspeptin (KP), the endogenous ligand of GPR54, is a mammalian amidated neurohormone, which belongs to the RF-amide peptide family. However, in contrast with the related members of the RF-amide family, little information is available regarding its role in the gastrointestinal motility. With regard to the recent data suggesting KP play an important role in food intake, and while gastrointestinal motility are closely related to it. Thus, in the present work, effects of central administration of KP-13, one of the endogenous active isoforms, on gastrointestinal motility were investigated...

Irritable bowel syndrome (IBS) is one of the most common gastrointestinal (GI) disorders. Despite its prevalence, the pathophysiology of IBS is not well understood though multiple peripheral and central factors are implicated. Recent studies suggest a role for alterations in gut microbiota in IBS. Significant advances in next-generation sequencing technology and bioinformatics, and the declining cost has now allowed us to better investigate the role of gut microbiota in IBS. In the following review, we propose gut microbiota as a unifying factor in the pathophysiology of IBS...

The enteric nervous system (ENS) of the gastrointestinal tract controls many diverse functions, including motility and epithelial permeability. Perturbations in ENS development or function are common, yet there is no human model for studying ENS-intestinal biology and disease. We used a tissue-engineering approach with embryonic and induced pluripotent stem cells (PSCs) to generate human intestinal tissue containing a functional ENS. We recapitulated normal intestinal ENS development by combining human-PSC-derived neural crest cells (NCCs) and developing human intestinal organoids (HIOs)...

The multifunctional neuropeptide calcitonin gene-related peptide (CGRP) and its receptor are expressed throughout the gastrointestinal tract. Previous studies have shown that CGRP has roles in intestinal motility, water secretion, and inflammation. Furthermore, animal studies have demonstrated CGRP involvement in diarrhea secondary to C. difficile and food allergies. Diarrhea thus provides a convenient bioassay of CGRP activity in the GI system. In this proof of principle study, we report that prophylactic administration of an anti-CGRP antibody is able to block CGRP-induced diarrhea in mice...

: Small intestinal muscularis externa macrophages have been associated with interstitial cells of Cajal (ICC). They have been proposed to play various roles in motility disorders and to take part in a microbiota-driven regulation of gastrointestinal motility. Our objective was to understand the reaction of resident macrophages of the musculature to a pro-inflammatory stimulator, lipopolysaccharide (LPS). Mice were injected with LPS or saline and sacrificed after 6 hours. Whole mounts were stained with antibodies toward CD169, ionized calcium-binding adaptor molecule 1 (iba1) (microglial/macrophage marker) and heme oxygenase-1 (HO-1)...
