Neuroprotective effects of whey and buttermilk-based formulas on a DSS-induced colitis murine model.

Inflammatory bowel disease is a gut-brain axis disorder that comprises chronic inflammatory conditions affecting the gastrointestinal tract, where alterations in the mood of patients are common. Gut-brain axis is a bidirectional communication that link gut and brain. The close association between inflammatory bowel disease and neuroinflammation has far-reaching implications, as is increasingly recognized as a contributing factor to neuropsychiatric and neurodegenerative diseases.

Involvement of NO/cGMP Signaling Pathway, Ca and K Channels on Spasmolytic Effect of Everlasting Flower Polyphenolic Extract ( (L.) Moench).

Functional gastrointestinal diseases (FGID) are worldwide prevalent conditions. Pharmacological treatments can be ineffective, leading the population to turn to herbal or traditional remedies. (L.

The Potential Role of Everlasting Flower ( Moench) as an Antihypertensive Agent: Vasorelaxant Effects in the Rat Aorta.

Helichrysum stoechas (L.) Moench (H. stoechas) is a medicinal plant traditionally used in the Iberian Peninsula to treat different disorders such as arterial hypertension.

Intestinal serotonergic system is modulated by Toll-like receptor 9.

Intestinal serotonergic system is a key modulator of intestinal homeostasis; however, its regulation is still unclear. Toll-like receptor 9 (TLR9), an innate immune receptor, detects different external agents in the intestine, preserving intestinal integrity. Since little is known about TLR9 role in the intestine, our aim was to address the potential regulation between TLR9 and intestinal serotonergic system.

Jasonia glutinosa (L.) DC., a traditional herbal medicine, reduces inflammation, oxidative stress and protects the intestinal barrier in a murine model of colitis.

Jasonia glutinosa (L.) DC., known as rock tea (RT), is traditionally used in Spain as a digestive due to its beneficial properties in bowel disorders.

Different mechanisms of actions of genistein, quercetin on spontaneous contractions of rabbit duodenum.

Flavonoids are known to relax precontracted intestinal smooth muscle and delay intestinal transit or intestinal peristalsis. The aim of this study was to determine the effects of genistein and quercetin on spontaneous contractions of rabbit duodenum in vitro in an organ bath. Genistein and quercetin (0.

Roles of Toll-Like Receptor 4, IκB Kinase, and the Proteasome in the Intestinal Alterations Caused by Sepsis.

Background: Lipopolysaccharide decreases intestinal contractility and induces the production of cytokines, which play an important role in the pathogenesis of sepsis.

Aim: The objective of the present study was to examine the role of Toll-like receptor 4, IκB kinase, and the proteasome in the intestinal alterations induced by lipopolysaccharide.

Methods: Sepsis was induced in rabbits by intravenous injection of lipopolysaccharide.

Mitogen activated protein kinases blockade improves lipopolysaccharide-induced ileal motor disturbances.

Background: several diseases such as sepsis can affect the ileum. Lipopolysaccharide (LPS), an endotoxin present in the cell wall of gram negative bacteria, is a causative agent of sepsis.

Objectives: the aims of this study were: a) to investigate the role of mitogen activated protein kinases (MAPKs) in the effect of LPS on the acetylcholine-induced contractions of rabbit ileum; and b) to study the localization of MAPKs in the ileum.

Nuclear factor κB is a key transcription factor in the duodenal contractility alterations induced by lipopolysaccharide.

Alterations in intestinal motility are one of the features of sepsis induced by lipopolysaccharide (LPS). This study investigated the role of the nuclear transcription factor κB (NF-κB) in the LPS-induced duodenal contractility alterations, generation of reactive oxygen species (ROS) and production of cytokines in rabbit duodenum. Rabbits were treated with saline, LPS, sulfasalazine + LPS, pyrrolidinedithiocarbamate (PDTC) + LPS or RO 106-9920 + LPS.

Trolox reduces the effect of ethanol on acetylcholine-induced contractions and oxidative stress in the isolated rabbit duodenum.

Trolox is a hydrophilic analogue of vitamin E and a free radical scavenger. Ethanol diminishes the amplitude of spontaneous contractions and acetylcholine (ACh)-induced contractions in rabbit duodenum. The aim of this work was to study the effect of Trolox on the alterations induced by ethanol on contractility and lipid peroxidation in the duodenum.

Role of TLR4 and MAPK in the local effect of LPS on intestinal contractility.

Objectives: Lipopolysaccharide (LPS) has been shown to alter intestinal contractility. Toll-like receptor 4 (TLR4), K(+) channels and mitogen-activated protein kinases (MAPKs) have been proposed to be involved in the mechanism of action of LPS. The aim of this study was to determine the role of TLR4, K(+) channels and MAPKs (p38, JNK and MEK1/2) in the local effect of LPS on the acetylcholine (ACh)-induced contractions in rabbit small intestine in vitro.

Contractile effect of tachykinins on rabbit small intestine.

Aim: To study the role of the tachykinin receptors in spontaneous contractions of longitudinal and circular smooth muscle from rabbit small intestine and to determine the mechanism of action of Substance P (SP).

Methods: Rabbit duodenum, jejunum and ileum segments were prepared. The spontaneous contractions of longitudinal and circular smooth muscle were recorded using a computer via an isometric force transducer.

Lipopolysaccharide-induced intestinal motility disturbances are mediated by c-Jun NH2-terminal kinases.

Background: Lipopolysaccharide (LPS) is a causative agent of sepsis. Many alterations, such as intestinal motility disturbances, have been attributed to LPS.

Aims: Here we investigated the role of c-Jun NH(2)-terminal kinases (JNK) in the effect of LPS on intestinal motility, the oxidative stress status and the cyclooxygenese-2 (COX-2) expression.

Intestinal effects of lipopolysaccharide in rabbit are mediated by cyclooxygenase-2 through p38 mitogen activated protein kinase.

The mediators of the pathophysiological symptoms of septic shock are not completely understood. The intracellular signalling mechanisms of lipopolysaccharide (LPS)-induced effects need further investigation. This study investigates (1) the role of COX-2 in the effect of LPS on (a) the KCl, acetylcholine and prostaglandin E₂-induced contractions of rabbit duodenum and (b) the oxidative stress status in plasma and intestine and (2) the relationship between p38 MAPK and COX-2 expression in rabbit duodenum.

PGE(2) receptors and their intracellular mechanisms in rabbit small intestine.

The effects of PGE(2) on longitudinal smooth muscle, the intracellular mechanisms involved, and the localization of EP receptors were investigated in rabbit small intestine. PGE(2) evoked contractions in small intestine that were reduced by tetrodotoxin and hexamethonium. 17-Phenyl trinor PGE(2), sulprostone, misoprostol and 16,16-dimethyl PGE(2) evoked contractions.
