Persistent activation of signal transducers and activators of transcription 3 (STAT3) is commonly detected in many types of cancer including pancreatic cancer. Whether STAT3 is activated in stem cell-like pancreatic cancer cells and the effect of STAT3 inhibition, is still unknown. Flow cytometry was used to isolate pancreatic cancer stem-like cells which are identified by both aldehyde dehydrogenase (ALDH)-positive (ALDH+) as well as cluster of differentiation (CD) 44-positive/CD24-positive subpopulations (CD44+/CD24+)...

BACKGROUND: The inflammatory bowel diseases (IBD), Crohn's disease (CD) and ulcerative colitis (UC) have been associated with an increased risk of preterm birth. MATERIAL AND METHODS: We identified all 246 singleton preterm births among women with IBD between July 2006 and December 2010 as cases and an equal number of controls with IBD from the Swedish national health registers, matched by maternal age, parity and IBD diagnosis (CD/UC). From register data and medical charts, we obtained information on reproductive history, comorbidity, disease activity and drug treatment (corticosteroids, 5-aminosalicylates, sulfasalazine, thiopurines and anti-TNF) as risk factors for preterm birth...

The simultaneous realization of high device efficiency, stable color spectra, high color rendering index (CRI), low efficiency roll-off and long operational lifetime in a fluorescent white organic light-emitting diode (WOLED) still re-mains a big challenge. Here, we demonstrate high-performance conventional fluorescent dopants-based fluorescent WOLEDs by strategic management of singlet and triplet excitons within an efficient emissive zone. This design consists of two separated red/green sub-EMLs with ultralow doping concentration and a sandwiched sub-EML doped the red and green fluorescent dyes with a relatively high concentration, which can harness all electrogenerated excitons and reduce the energy loss at the utmost extent...

BACKGROUND: Paneth cell dysfunction has been implicated in a subset of Crohn's disease (CD) patients. We previously stratified clinical outcomes of CD patients by using Paneth cell phenotypes, which we defined by the intracellular distribution of antimicrobial proteins. Animal studies suggest that Paneth cells shape the intestinal microbiome. However, it is unclear whether Paneth cell phenotypes alter the microbiome complexity in CD subjects. Therefore, we analyzed the correlation of Paneth cell phenotypes with mucosal microbiome composition and ileal RNA expression in pediatric CD and noninflammatory bowel disease (non-IBD) patients...

Cluster of differentiation (CD)44 has been implicated in cancer metastasis to bone. Clinical and experimental studies have suggested that the standard isoform of CD44 (CD44s) and the variant isoform of CD44 (CD44v) enhance metastasis. The present study examined the differential roles of CD44s and CD44v, particularly CD44v8-10, in the development of bone metastases. For this purpose, MDA-MB-231 human breast cancer cells and A549 human lung cancer cells were stably transduced with epithelial splicing regulatory protein 1 (ESRP1), which regulates the alternative splicing of several genes, including CD44...

A subpopulation of breast cancer cells with cluster of differentiation (CD)44-positive and CD24-negative expression has been reported to have stem cell properties and to have a higher tumorigenic capacity than other cells. However, the clinicopathological characteristics of this subpopulation are not fully understood. In this study, we aimed to identify the correlations between the expression of CD44 and CD24 and clinicopathological parameters and overall survival. We studied specimens from 262 patients with invasive breast cancer...

Analyzing the concentrations of heavy metals in the sera of umbilical cord blood samples can provide useful information about prenatal exposure to environmental agents. An analytical method based on ICP-MS to simultaneously determine multiple elements in umbilical cord blood samples was developed for assessing the in utero exposure to metallic and metalloid elements. The method only required as little as 100 μL of serum diluted 1:25 for direct analysis. Matrix-matched protocol was used to eliminate mass matrix interference and kinetic energy discrimination mode was used to eliminate the polyatomic ion interference...

BACKGROUND: Laparoscopic roux-en-Y gastric bypass (LRYGB) has gained increasing popularity as the primary procedure of choice for the management of patients with morbid obesity. Despite the advances, a few patients will still develop complications and predicting these early complications in morbidly obese patients can prove to be difficult. Radiological investigations have limited diagnostic value and have associated side effects and cost. We propose that C-reactive protein (CRP) is a useful predictor for early postoperative complications...

INTRODUCTION: The establishment of prognostic models for Crohn's disease (CD) is highly desirable, as they have the potential to guide physicians in the decision-making process concerning therapeutic choices, improving patients' health and quality of life. Our aim was to derive models for disabling CD disease and reoperation based solely on clinical/demographic data. METHODS: A multicentric and retrospectively-enrolled cohort of CD patients, subject to early surgery or immunosuppression, was analized to build Bayesian network models and risk matrices...

PURPOSE: Pediatric Cushing's disease (CD) is rare and there are limited data on the long-term outcomes. We assessed CD recurrence, body composition, pituitary function and psychiatric comorbidity in a cohort of pediatric CD patients. METHODS: Retrospective review of 21 CD patients, mean age at diagnosis 12.1 years (5.7-17.8), managed in our center between 1986 and 2010. Mean follow-up from definitive treatment was 10.6 years (2.9-27.2). RESULTS: Fifteen patients were in remission following transsphenoidal surgery (TSS) and 5 were in remission following TSS + external pituitary radiotherapy (RT)...

Cadmium (Cd) pollution in vegetable crops has become a serious problem in recent years. Owing to the limited availability of arable land resources, large areas of Cd-contaminated lands are inevitably being used for the production of vegetables, posing great risks to human health via the food chain. However, strategies to improve yield and reduce Cd concentration in crops grown in contaminated soils are being developed. In the present study, using pot experiments, we investigated the effects of two slow-release nitrogen fertilizers (SRNFs), resin-coated ammonium nitrate (Osmocote313s), and resin-coated urea (urea620), on the growth and Cd concentration of the Cd-contaminated pakchoi...

Light-emitting diodes based on organic (OLEDs) and colloidal quantum dot (QLEDs) are widely considered as next-generation display technologies because of their attractive advantages such as self-emitting and flexible form factor. The OLEDs exhibit relatively high efficiency, but their color saturation is quite poor compared with that of QLEDs. In contrast, the QLEDs show very pure color emission, but their efficiency is lower than that of OLEDs currently. To combine the advantages and compensate for the weaknesses of each other, we propose a hybrid tandem structure which integrates both OLED and QLED in a single device architecture...
