BACKGROUND: Gastric motility is controlled by the autonomic and enteric nervous systems and by interstitial cells of Cajal (ICCs). Although histamine is known to be released from enterochromaffin-like cells in the gastric mucosa, its regulatory roles in gastric motility are still controversial. Therefore, we investigated the functional roles of histamine in gastric motility. METHODS: Stomach preparations from hamsters were used because the stomach of hamsters can be easily separated into the forestomach and the glandular stomach...

REVIEW

Chronic intestinal pseudo-obstruction (CIPO) is a severe form of gastrointestinal dysmotility (often due to derangement of the innervation/smooth muscle/interstitial cells of Cajal) with recurrent episodes of intestinal subocclusion mimicking a mechanical obstruction. Because of its complexity and heterogeneity, CIPO is often misdiagnosed or remains unrecognized until advanced stages. Management is a critical aspect in CIPO patient care. So far, most prokinetic drugs have not proven efficacy in restoring intestinal propulsion, thus nutritional support, fluid/electrolyte replacement, and antibiotics are the mainstay of treatment...

Seesaw nystagmus is characterized by cyclic eye movements with a conjugate torsional component and a dissociated vertical component. In the first half of the cycle, one eye elevates and intorts, whereas the other eye depresses and extorts. The pattern is reversed in the remaining half of the cycle. We describe a patient with a giant pituitary adenoma who developed pendular seesaw nystagmus. Disturbance in the visuovestibular system is postulated to contribute to this form of seesaw nystagmus. Lesions compressing the optic chiasm and the accessory optic system could interrupt the transmission of retinal error signals to the inferior olivary nucleus and the interstitial nucleus of Cajal, thus interfering with the adaptive mechanism of the vestibulo-ocular reflex and leading to pendular seesaw nystagmus...

Microsatellite instability (MSI) is a hallmark tool for Lynch syndrome (LS) screening and a prognostic marker for sporadic colorectal cancer (CRC). In regions with limited resources and scarce CRC molecular characterization as South America, the implementation of universal MSI screening is under debate for both its purposes. We sought to estimate the frequency of BAT26 in colorectal adenocarcinomas and to determine associated clinical and histological features. Consecutive patients from a CRC registry were included...

REVIEW
Khadeejah T Sultan, Song-Hai Shi
First described by Ramon y Cajal as 'short-axon' cells over a century ago, inhibitory interneurons in the cerebral cortex make up ~20-30% of the neuronal milieu. A key feature of these interneurons is the striking structural and functional diversity, which allows them to modulate neural activity in diverse ways and ultimately endow neural circuits with remarkable computational power. Here, we review our current understanding of the generation of cortical interneurons, with a focus on recent efforts to bridge the gap between progenitor behavior and interneuron production, and how these aspects influence interneuron diversity and organization...

INTRODUCTION: Functional health, a reliable parameter of the impact of disease, should be used systematically to assess prognosis in paediatric intensive care units (PICU). Developing scales for the assessment of functional health is therefore essential. The Paediatric Overall and Cerebral Performance Category (POPC, PCPC) scales have traditionally been used in paediatric studies. The new Functional Status Scale (FSS) was designed to provide more objective results. This study aims to confirm the validity of the FSS compared to the classic POPC and PCPC scales, and to evaluate whether it may also be superior to the latter in assessing of neurological function...

Lung cancer is one of the most aggressive tumours with very low life expectancy. Altered microRNA expression is found in human tumours because it is involved in tumour growth, progression and metastasis. In this study, we analysed microRNA expression in 47 lung cancer biopsies. Among the most downregulated microRNAs we focussed on the miR-99a characterisation. In vitro experiments showed that miR-99a expression decreases the proliferation of H1650, H1975 and H1299 lung cancer cells causing cell cycle arrest and apoptosis...

Diabetic gastroparesis (DGP) is an important complication of diabetes, and seriously impacts the patient's quality of life. In the present paper, the authors summarize national and international research on the mechanism of acupuncture therapy in improving DGP and the pathogenesis of DGP over the past 10 years. The authors illustrate the mechanism of acupuncture underlying the improvement in DGP as follows:1) the effect on autonomic nerves and neurons of the central nervous system; 2) promoting restoration of the enteric nervous system; 3) the effect on Cajal interstitial cells; 4) improving gastrointestinal hormone disorder; 5) improving hyperglycemic state; 6) the effect on gastric smooth muscle...

Chronic constipation (CC) and idiopathic megacolon (IMC) occur frequently in cats. The aim of the study was to investigate the effects of a multi-strain probiotic (SLAB51™) in constipated cats (n=7) and in patients with megacolon and constipation (n=3). Ten pet cats with a diagnosis of chronic constipation, non-responsive to medical management received orally 2×10(11) bacteria daily for 90 days. For microbiota analysis, selected bacterial groups were analysed by qPCR. Histological samples in megacolons were evaluated for interstitial cells of Cajal (ICC), enteric neurons, and neuronal apoptosis...

Diabetes mellitus (DM) can affect the structure and function of the colon promoting commonly encountered lower gastrointestinal symptoms such as constipation, diarrhea, abdominal distention, bloating, and abdominal pain. Specific colonic disorders for which adults with DM are at greater risk include chronic constipation, enteropathic diarrhea, colorectal cancer (CRC), inflammatory bowel disease, microscopic colitis, and Clostridium difficile colitis. Smooth muscle structure and function, density of the interstitial cells of Cajal, and the health and function of the autonomic and enteric nerves of the colon are all potential affected by DM...

INTRODUCTION: Gastrointestinal stromal tumors (GISTs), originating from Cajal cells, are most commonly located in the stomach; therefore they can be found in the specimens excised during bariatric operations. The global prevalence of GISTs is about 130 cases per million population. Morbidity differs depending on geographical latitude. Although surgery is the treatment of choice for GISTs, 40-50% of patients after radical surgical treatment will have a relapse or metastases. AIM: To analyze the incidence of GISTs in patients undergoing bariatric surgery and to verify whether an operation performed according to the bariatric protocol is oncologically radical in case of GIST...

Gastrointestinal stromal tumors (GISTs) include 80% of gastrointestinal mesenchymal tumors that originate from interstitial Cajal cells and include 0.1-3% of GI malignancies, and the stomach is the most commonly involved organ. The only potentially curative treatment is surgical resection with clear margins. Although laparoscopic resection of small GISTs is a standard treatment, there is controversy about laparoscopic surgical resection for large and giant GISTs. A 52-year-old woman, a known case of large GIST of the stomach that was under neoadjuvant imatinib therapy, was admitted to the emergency department due to acute massive gastrointestinal bleeding (GIB)...

Interstitial Cells of Cajal (ICC) initiate and actively propagate electrical events in the gastrointestinal tract known as slow-waves. The slow-waves coordinate the contraction of the gastrointestinal tract necessary for breakdown and mixing of ingested food. Degradation of the ICC numbers has been linked to several gastrointestinal motility disorders. However, limitations in imaging techniques and techniques for the quantification of ICC network structure have hindered our understanding of these disorders...

The interstitial cells of Cajal (ICC) generate electrophysiological events called slow waves that regulate the motility of the gastrointestinal (GI) tract. Recent studies have demonstrated that the Ca(2+)-activated Cl(-) -channel, encoded by the anoctamin1 (Ano1) protein, has a major role in regulating intestinal slow waves and motility. The main aim of this study was to develop a multi-scale mathematical model capable of simulating both normal slow wave entrainment and the effects of Ano1 knockout (KO) on the normal activity...
