The gut microbiota has been recognized as an important factor in the development of metabolic diseases such as obesity and is considered an endocrine organ involved in the maintenance of energy homeostasis and host immunity. Dysbiosis can change the functioning of the intestinal barrier and the gut-associated lymphoid tissues (GALT) by allowing the passage of structural components of bacteria, such as lipopolysaccharides (LPS), which activate inflammatory pathways that may contribute to the development of insulin resistance...

Hyperkalemia (HK) occurs often among patients with chronic kidney disease (CKD) and heart failure (HF) and those treated with renin-angiotensin-aldosterone system inhibitors (RAASI). Even small deviations from normal potassium levels carry increased risk of mortality. Patiromer is approved for treatment of HK and has been shown in clinical trials to reduce serum potassium among patients with HK and comorbid conditions. Areas covered: We review pooled data from two clinical trials of patiromer in patients with CKD and HK, safety of patiromer in special populations, drug-drug interaction (DDI) studies, and other studies in healthy volunteers...

Behçet's disease (BD) is a systemic inflammatory disorder involving the oral and genital mucosa, skin, eyes, gastrointestinal tract, joints, vasculature, and nervous. The gastrointestinal lesions accompanying with BD can extend along the full length of the tract, from the mouth to the anus, and show various clinical characteristics which is difficult to be differentiate from the other inflammatory bowel diseases including ulcerative colitis and Crohn's disease. Hence, the differential diagnosis is difficult and can affect treatment outcomes...

Psychosocial stress may impair immune functions and provoke the development of pathologies. The underlying communication between the brain and the immune system is being studied predominantly in rodents. However, pigs offer several advantages as preclinical models for humans because pigs are more similar to humans than rodents in many anatomical and physiological characteristics. Unlike in rodents, the main stress-induced glucocorticoid in humans and pigs is cortisol with a similar circadian rhythm. In this study, we summarize data on short-term and long-term effects of social stress in pigs for their immunity and neuroendocrine regulation with consequences for their health and well-being...

House mice ( Mus musculus ) thrive in large urban centers worldwide. Nonetheless, little is known about the role that they may play in contributing to environmental contamination with potentially pathogenic bacteria. Here, we describe the fecal microbiome of house mice with emphasis on detection of pathogenic bacteria and antimicrobial resistance genes by molecular methods. Four hundred sixteen mice were collected from predominantly residential buildings in seven sites across New York City over a period of 13 months...

BACKGROUND: Previous data suggest that fecal S100A12 has clinical utility as a biomarker of chronic gastrointestinal inflammation (idiopathic inflammatory bowel disease) in both people and dogs, but the effect of gastrointestinal pathogens on fecal S100A12 concentrations is largely unknown. The role of S100A12 in parasite and viral infections is also difficult to study in traditional animal models due to the lack of S100A12 expression in rodents. Thus, the aim of this study was to evaluate fecal S100A12 concentrations in a cohort of puppies with intestinal parasites (Cystoisospora spp...

Altered epigenetic regulation is central to many human diseases, including cancer. Over the past two decade, major advances have been made in our understanding of the role of epigenetic alterations in carcinogenesis, particularly for DNA methylation, histone modifications and non-coding RNAs. Aberrant hypermethylation of DNA at CpG islands is a well-established phenomenon that mediates transcriptional silencing of tumor suppressor genes, and it is an early event integral to gastrointestinal cancer development...

Nutmeg is a traditional Chinese medicine used to treat gastrointestinal diseases. Some reports indicated that nutmeg has hepatoprotective activity. In this study, a thioacetamide (TAA)-induced acute liver injury model in mice was used to explore the mechanism of the protective effects of nutmeg extract (NME), including its major bioactive component myrislignan. The results indicated that NME could effectively protect TAA-induced liver damage as assessed by recovery of increased serum liver transaminases, decrease hepatic oxidative stress and lower hepatic inflammation...

OBJECTIVES: Alzheimer's disease (AD) has become the primary cause of dementia. It shows a progressive cognitive dysfunction with degenerating neurons. Acetylcholine receptors (AChRs) propagate the cognitive ability and it consists of two primary members namely muscarinic (mAChRs) and nicotinic receptors (nAChRs). Where mAChRs is G-protein coupled receptor, (nAChRs) are ligand-gated ion channels. The conventional therapeutic regimen for AD consists of three acetylcholinestearse inhibitors while a single NMDA receptor antagonist...

Rendu-Osler-Weber disease, also known as hereditary hemorrhagic telangiectasia, is a rare autosomal dominant disorder which is often characterized by recurrent epistaxis, mucocutaneous and gastrointestinal telangiectasias, and visceral arteriovenous malformations. Patients with gastrointestinal involvement can present with a wide spectrum of severity, which may vary from uncomplicated iron deficiency anemia to continuous and refractory bleeding. We present the case of a 62-year-old female, who was admitted with anemia following several episodes of melena, and whose endoscopic examination revealed multiple angiodysplasias in the stomach and small bowel...

Large bowel obstruction can result in significant morbidity and mortality, especially in cases of acute complete obstruction. There are many possible causes, the most common in adults being colorectal cancer. Endometriosis is a benign disease, and the most affected extragenital location is the bowel, especially the rectosigmoid junction. However, transmural involvement and acute occlusion are very rare events. We report an exceptional case of acute large bowel obstruction as the initial presentation of endometriosis...

Duodenal adenocarcinoma (ADC) represents only 0.3% of gastrointestinal neoplasms. With the frequency being higher between the ages of 40 and 60, it is predominantly located in the second part of the duodenum and around the periampullary region. Symptoms are nonspecific, so the majority of patients present with advanced disease. Neoadjuvant chemotherapy is a therapeutic option that has not been well studied. The global literature includes only isolated reports on this subject. This is why we are presenting the following case: a 60-year-old female patient with a locally advanced, inoperable duodenal ADC received neoadjuvant chemotherapy...

Though the detailed pathological mechanism of post-infectious irritable bowel syndrome (PI-IBS) remains unclear, accumulating evidence indicates that oxidative stress and inflammation are implicated in the process of PI-IBS. Oxidative stress and inflammation are regulated by Nrf2 and NF-κB signaling pathways, respectively. EphA2, a member of Eph receptor family, promotes oxidative stress and inflammatory responses via regulation of Nrf2 and NF-κB signaling pathways in various types of human diseases. Understanding the mechanisms by which EphA2 regulate oxidative stress and inflammation in PI-IBS is important for the development of new strategies to treat PI-IBS...
