State Key Laboratory of Virology , Key Laboratory of Combinatorial Biosynthesis and Drug Discovery (MOE) , Hubei Provincial Key Laboratory of Developmentally Originated Disease , Wuhan University School of Pharmaceutical Sciences , Wuhan 430071 , China . Email:

Near-infrared II fluorescence imaging holds great promise for imaging and imaging-guided surgery with deep penetration and high spatiotemporal resolution. However, most NIR-II aromatic luminophores suffer from the notorious aggregation-caused quenching (ACQ) effect in the aqueous solution, which largely hinders their biomedical application . In this study, the first NIR-II organic aggregation-induced emission (AIE) fluorophore (), encapsulated as nanoparticles ( dots) for biomedical imaging, was designed and synthesized. Read More

Contribution of ghrelin to functional gastrointestinal disorders' pathogenesis.

World J Gastroenterol 2019 Feb;25(5):539-551

Department of Basic Medical Science, Laboratory of Biology, School of Medicine, University of Athens, Athens 11527, Greece.

Functional gastrointestinal disorders (FGID) are heterogeneous disorders with a variety of clinical manifestations, primarily defined by signs and symptoms rather than a definite underlying cause. Their pathophysiology remains obscure and, although it is expected to differ according to the specific FGID, disruptions in the brain-gut axis are now thought to be a common denominator in their pathogenesis. The hormone ghrelin is an important component of this axis, exerting a wide repertoire of physiological actions, including regulation of gastrointestinal motility and protection of mucosal tissue.

Recent understanding of the pathophysiology of functional dyspepsia: role of the duodenum as the pathogenic center.

J Gastroenterol 2019 Feb 14. Epub 2019 Feb 14.

Division of Gastroenterology, Department of Gastroenterology, Hyogo College of Medicine, Mukogawa-cho 1-1, Nishinomiya, Hyogo, 663-8501, Japan.

Over almost 30 years since functional dyspepsia (FD) was defined, researchers have endeavored to elucidate the pathophysiology of functional gastrointestinal disorders. Now a consensus is emerging that the gastric symptoms of FD are caused mainly by gastric motility abnormalities and gastric hypersensitivity. The involvement of other causative factors including acid, Helicobacter pylori, psychological factors, and diet has been debated, but how they are involved in the manifestation of dyspeptic symptoms remains unclear.

Ulcer-associated cell lineage expresses genes involved in regeneration and is hallmarked by high neutrophil gelatinase-associated lipocalin (NGAL) levels.

J Pathol 2019 Feb 11. Epub 2019 Feb 11.

Centre of Molecular Inflammation Research, NTNU, Norwegian University of Science and Technology, Trondheim, Norway.

Neutrophil gelatinase associated lipocalin (NGAL), also known as Lipocalin 2, is an antimicrobial protein, encoded by the gene LCN2, strongly upregulated in inflammatory bowel disease (IBD) and a promising biomarker for IBD. Here we demonstrate that NGAL is highly expressed in all parts of pyloric metaplasia, also known as the ulcer-associated cell lineage (UACL), a metaplastic cell lineage suggested to play a role in wound healing in Crohn's disease (CD). We further show NGAL expression in regenerative intestinal crypts and in undifferentiated patient-derived colonoids. Read More

Melatonin treatment alleviates spinal cord injury-induced gut dysbiosis in mice.

J Neurotrauma 2019 Jan 29. Epub 2019 Jan 29.

No. 10 Jiaomen North Road, Fengtai DistrictBeijing, China , 100068 ;

Spinal cord injury (SCI) disturbs the autonomic nervous system and induces dysfunction in multiple organs/tissues, such as the gastrointestinal (GI) system. The neuroprotective effects of melatonin in SCI models have been reported; however, it is unclear whether the beneficial effects of melatonin are associated with alleviation of gut dysbiosis. In this study, we showed that daily intraperitoneal injection with melatonin following spinal cord contusion at thoracic level 10 in mice improved intestinal barrier integrity and GI motility, reduced the expression levels of certain pro-inflammatory cytokines, improved animal weight gain and metabolic profiling, and promoted locomotor recovery.

Effects of the long-term storage of human fecal microbiota samples collected in RNAlater.

Sci Rep 2019 Jan 24;9(1):601. Epub 2019 Jan 24.

Danone Nutricia Research, Innovation, Science and Nutrition Department, RD 128 - Avenue de la Vauve, 91767, Palaiseau, France.

The adequate storage of fecal samples from clinical trials is crucial if analyses are to be performed later and in long-term studies. However, it is unknown whether the composition of the microbiota is preserved during long-term stool storage (>1 year). We therefore evaluated the influence of long-term storage on the microbiota composition of human stool samples collected in RNAlater and stored for approximately five years at -80 °C. Read More

Motilin: from gastric motility stimulation to hunger signalling.

Nat Rev Endocrinol 2019 Jan 23. Epub 2019 Jan 23.

Translational Research in Gastrointestinal Disorders (TARGID), Department of Chronic Diseases, Metabolism and Ageing (CHROMETA), KU Leuven, Leuven, Belgium.

After the discovery of motilin in 1972, motilin and the motilin receptor were studied intensely for their role in the control of gastrointestinal motility and as targets for treating hypomotility disorders. The genetic revolution - with the use of knockout models - sparked novel insights into the role of multiple peptides but contributed to a decline in interest in motilin, as this peptide and its receptor exist only as pseudogenes in rodents. The past 5 years have seen a major surge in interest in motilin, as a series of studies have shown its relevance in the control of hunger and regulation of food intake in humans in both health and disease.

The MOVEMENT Trial.

J Am Heart Assoc 2019 Jan;8(2):e010152

1 Department of Molecular Medicine and Surgery Karolinska Institutet Stockholm Sweden.

Background Morphine administration is a strong predictor of delayed onset of action of orally administered ticagrelor in patients with ST-segment-elevation myocardial infarction, likely because of impaired gastrointestinal motility. The aim of this study was to evaluate whether the peripheral opioid antagonist methylnaltrexone could improve pharmacodynamics and pharmacokinetics of orally administered ticagrelor in patients with ST-segment-elevation myocardial infarction receiving morphine. Methods and Results The MOVEMENT (Methylnaltrexone to Improve Platelet Inhibition of Ticagrelor in Morphine-Treated Patients With ST-Segment Elevation Myocardial Infarction) trial was a multicenter, prospective, randomized, controlled trial in patients with ST-segment-elevation myocardial infarction treated with morphine and ticagrelor.

Overview of Deep Learning in Gastrointestinal Endoscopy.

Gut Liver 2019 Jan 11. Epub 2019 Jan 11.

Department of Internal Medicine, Kyung Hee University School of Medicine, Seoul, Korea.

Artificial intelligence is likely to perform several roles currently performed by humans, and the adoption of artificial intelligence-based medicine in gastroenterology practice is expected in the near future. Medical image-based diagnoses, such as pathology, radiology, and endoscopy, are expected to be the first in the medical field to be affected by artificial intelligence. A convolutional neural network, a kind of deep-learning method with multilayer perceptrons designed to use minimal preprocessing, was recently reported as being highly beneficial in the field of endoscopy, including esophagogastroduodenoscopy, colonoscopy, and capsule endoscopy.

Arcuate Nucleus Orexin-A Signaling Alleviates Cisplatin-Induced Nausea and Vomiting Through the Paraventricular Nucleus of the Hypothalamus in Rats.

Front Physiol 2018 17;9:1811. Epub 2018 Dec 17.

Pathophysiology Department, School of Basic Medicine, Qingdao University, Qingdao, China.

The most common side effects of cisplatin chemotherapy are nausea and vomiting, and the overwhelming majority of research studies on the mechanism of cisplatin-induced nausea have been focused on the "vomiting center." As a modulatory center of gastric motility, the roles of the hypothalamus in nausea and vomiting remain unclear. In the present study, we investigated the effects of exogenous orexin-A injected into the arcuate nucleus (ARC) on cisplatin-induced nausea and vomiting, and the possible underlying mechanism.

Multiple rapid swallow testing in patients with gastroesophageal reflux disease.

Indian J Gastroenterol 2018 Nov 7;37(6):555-558. Epub 2019 Jan 7.

Department of Gastroenterology, Gleneagles Global Health City, 439, Cheran Nagar, Chennai, 600 100, India.

Patients with gastroesophageal reflux disease are commonly referred to a gastrointestinal motility unit for assessment of esophageal physiology tests prior to an anti-reflux procedure. On esophageal manometry, most patients have normal peristalsis; however, minor disorders of motility such as ineffective esophageal motility and fragmented peristalsis are not uncommon. Multiple rapid swallow (MRS) test is a provocative method for assessing peristaltic reserve in such patients. Read More

Fecal Microbiota Transplantation for the Critically Ill Patient.

Nutr Clin Pract 2019 Feb 18;34(1):73-79. Epub 2018 Dec 18.

Division of Gastroenterology & Hepatology, Johns Hopkins University School of Medicine, Baltimore, Maryland.

The gut microbiome has been implicated in a diversity of diseases, such as irritable bowel syndrome, inflammatory bowel disease, hepatic steatosis, metabolic syndrome, obesity, and anxiety. Current research also suggests the presence of a bidirectional relationship between the composition of the gut microbiome and critical illness. In the critical care setting, multiple factors (eg, use of antibiotics, aberrant nutrition, bloodstream infections, bowel ischemia, and abnormal bowel motility) strongly contribute to intestinal dysbiosis.
