REVIEW
Vivian C Nanagas, Anna Kovalszki
Hypereosinophilic syndrome and mastocytosis are relatively rare proliferative diseases encountered in the general population. However, allergists frequently consider these disorders in the differential of patients presenting with gastrointestinal, pulmonary, cutaneous, and allergic symptoms. Gastrointestinal symptoms are some of the most frequent and/or debilitating aspects of both disease states and in many cases lead to poor quality of life and functional limitation for the patient. They are the third most common clinical manifestation in hypereosinophilic syndrome and have been found to be the most distressful aspect of the disorder in those with systemic mastocytosis...

In this study, we analyzed and compared the properties of yeast Ulp1 protease in active inclusion bodies (IBs) as special protein immobilizate, and the soluble Ulp1 via oriented immobilization. Fusion of the N-terminal self-assembling peptide GFIL8 to the Ulp1 increased production of active IBs in Escherichia coli. Attachment of the N-terminal cellulose-binding module facilitated the constructed protein immobilized on the regenerated amorphous cellulose (RAC) with a binding capacity up to about 235 mg protein per gram of RAC...

BACKGROUND: Irritable bowel syndrome (IBS) is a chronic, recurring condition, prevalent in the general population. Current medication treatments usually leave patients undertreated. Nowadays, Chinese medicine (CM) is being considered as a promising treatment approach for IBS. However, due to methodological limitations, there is no strong evidence to support CM. Although IBS relapses are common, the relapse assessment has always been neglected in CM study designs. Meanwhile, in clinical practice and studies, it has been found that certain CM formulas can only benefit certain kinds of patients...

Enzymes from the thermolysin family are crucial factors in the pathogenesis of several diseases caused by bacteria and are potential targets for therapeutic interventions. Thermolysin encoded by the gene LIC13322 of the causative agent of leptospirosis, Leptospira interrogans , was shown to cleave proteins from the Complement System. However, the production of this recombinant protein using traditional refolding processes with high levels of denaturing reagents for thermolysin inclusion bodies (TL-IBs) solubilization results in poor recovery and low proteolytic activity probably due to improper refolding of the protein...

BACKGROUND/AIMS: Fecal soiling (FS) is the staining of underwear without loss of significant amounts of fecal material. It is frequently associated with defecation disorders in children. The aim of this study was to search for psychological and clinical correlates of adult patients with soiling. Clinically, the complaint of staining is confused with that of fecal incontinence (FI) in the mind of both patients and attending physicians. DESIGN: Observational study PATIENTS AND METHOD: We included 1454 consecutive outpatients (71% females)...

Antifreeze proteins (AFPs) inhibit ice growth in organisms living in cold environments. Hyperactive insect AFPs are particularly effective, binding ice through "anchored clathrate" motifs. It has been hypothesized that the binding of hyperactive AFPs to ice is facilitated by preordering of water at the ice-binding site (IBS) of the protein in solution. The antifreeze protein Tm AFP displays the best matching of its binding site to ice, making it the optimal candidate to develop ice-like order in solution...

OBJECTIVE: IBS is associated with an intestinal dysbiosis and faecal microbiota transplantation (FMT) has been hypothesised to have a positive effect in patients with IBS. We performed a randomised, double-blind placebo-controlled trial to investigate if FMT resulted in an altered gut microbiota and improvement in clinical outcome in patients with IBS. DESIGN: We performed this study in 52 adult patients with moderate-to-severe IBS. At the screening visit, clinical history and symptoms were assessed and faecal samples were collected...

Corticotropin-releasing hormone (CRH) mediates stress responses in the brain-gut axis. Administration of CRH modulates brain activation, for example by controlling the autonomic nervous system in response to colorectal distention. Here, we investigated the relationship between sympathoadrenal and hypothalamic-pituitary-adrenal (HPA) responses to colorectal distention in patients with irritable bowel syndrome (IBS). We enrolled 32 patients with IBS (16 women and 16 men) and 32 healthy subjects (16 women and 16 men), and randomly divided them between CRH and saline injection groups...

Background: Patients with microscopic colitis (MC) often present with abdominal pain and diarrhoea, and previous data suggest that there may be overlap between MC and irritable bowel syndrome (IBS). We evaluated the prevalence of IBS-type symptoms in patients with MC, and assess the impact of these symptoms on psychological health and quality of life. Methods: We conducted a cross-sectional survey of individuals with a histological diagnosis of MC, collecting demographic data, Rome III IBS-type symptoms, and mood, somatization, and quality of life data...

To achieve confidentiality, authentication, integrity of medical data, and support fine-grained access control, we propose a secure electronic health record (EHR) system based on attribute-based cryptosystem and blockchain technology. In our system, we use attribute-based encryption (ABE) and identity-based encryption (IBE) to encrypt medical data, and use identity-based signature (IBS) to implement digital signatures. To achieve different functions of ABE, IBE and IBS in one cryptosystem, we introduce a new cryptographic primitive, called combined attribute-based/identity-based encryption and signature (C-AB/IB-ES)...

INTRODUCTION AND HYPOTHESIS: Patients in gynecology outpatient clinics (GOPDs) may present with symptoms that do not correlate well with the observed pathology and are usually labelled as having a functional disorder or medically unexplained symptoms (MUS). Underlying central sensitivity syndrome (CSS) with central sensitization (CS) as a potential mechanism may be responsible for some of their symptoms. The aim of this study is to identify the proportion of women with central sensitivity syndrome attending GOPDs...

The pathogenesis of ME/CFS, a disease characterized by fatigue, cognitive dysfunction, sleep disturbances, orthostatic intolerance, fever, irritable bowel syndrome (IBS), and lymphadenopathy, is poorly understood. We report biomarker discovery and topological analysis of plasma metabolomic, fecal bacterial metagenomic, and clinical data from 50 ME/CFS patients and 50 healthy controls. We confirm reports of altered plasma levels of choline, carnitine and complex lipid metabolites and demonstrate that patients with ME/CFS and IBS have increased plasma levels of ceramide...

Alterations in gut microbiota are postulated to be an etiologic factor in the pathogenesis of irritable bowel syndrome (IBS). To determine whether IBS patients in China exhibited differences in their gut microbial composition, fecal samples were collected from diarrhea-predominant IBS (IBS-D) and healthy controls and evaluated by 16S ribosomal RNA gene sequence and quantitative real-time PCR. A mouse model of postinfectious IBS (PI-IBS) was established to determine whether the altered gut microbiota was associated with increased visceral hypersensitivity...

BACKGROUND AND AIM: Metformin has been shown to have anti-cytokine property. Lipopolysaccharide (LPS)- or repeated water avoidance stress (WAS)-induced visceral allodynia and increased gut permeability were proinflammatory cytokine-dependent responses, which were considered to be animal models of irritable bowel syndrome (IBS). We hypothesized that metformin improves symptoms in the patients with IBS by attenuating these visceral changes and tested the hypothesis in rats. METHODS: The threshold of the visceromotor response (VMR) induced by colonic balloon distention was measured...

Human phospholipid scramblase 1 (hPLSCR1) is an ATP independent, Ca2+ dependent transmembrane protein mediating bidirectional translocation of phospholipids across the lipid bilayer but the mechanism of scrambling is unknown. Determination of the hPLSCR1 structure would help understand the mechanism and its multi-functional property. Recombinant hPLSCR1 forms inclusion bodies (IBs), when over-expressed in E. coli BL21 (DE3) and recovery of active hPLSCR1 from IBs, were time-consuming and resulted in low protein yield...
