Abstract
BACKGROUND This study compared prucalopride, a selective, prokinetic, 5-HT4 receptor agonist, with polyethylene glycol 3350 + electrolytes (PEG3350), an osmotic laxative, on colonic motility parameters, primarily high-amplitude propagating contractions (HAPCs) in patients with chronic constipation. METHODS This randomized, cross-over, reader-blinded study was conducted at a single site in the USA. The study was open to men and women aged 18-75 years who met study inclusion criteria. Colonic manometry catheters were inserted the day before investigation. On the investigation days, patients received oral 2 mg prucalopride or 2 × 13.8 g PEG3350 in solution. The primary endpoint was HAPC count (threshold: mean amplitude ≥100 mmHg, propagation ≥20 cm [HAPC1 ]) in the 12 h after treatment administration. Analyses were also conducted at two co-primary thresholds: mean amplitude ≥75 mmHg, propagation ≥20 cm (HAPC2 ); and mean amplitude ≥75 mmHg, propagation ≥10 cm (HAPC3 ). Secondary endpoints included HAPC area under the curve (AUC), contraction force, amplitude, duration, and propagation velocity. KEY RESULTS Thirteen women were enrolled, with 12 completing the study. Significantly more HAPC1 (8.7 ± 2.06 vs 2.9 ± 2.06; p = 0.012) and HAPC2 (9.0 ± 2.11 vs 3.3 ± 2.11; p = 0.017) were observed in the 12-h periods with prucalopride than with PEG3350. Prucalopride significantly increased mean propagation distance and velocity (HAPC2 ) and mean AUC, force, and amplitude (HAPC3 ) compared with PEG3350. Adverse events were mild or moderate. CONCLUSIONS & INFERENCES Prucalopride was superior to PEG3350 in inducing HAPCs in patients with chronic constipation. ClinicalTrials.gov number NCT01707667.

Abstract
Euroleon coreanus (Okamoto) is widely distributed in China, and the larval stage can be treated as traditional Chinese medicine. However, the host-bacterium relationship remains unexplored, as there is a lack of knowledge on the microbial community of ant lions. Hence, in the current study, we explored the microbial community of the larval ant lion E. coreanus using Illumina MiSeq sequencing. Results indicated that a total of 10 phyla, 126 genera, and 145 species were characterized from the second instars of E. coreanus, and most of the microbes were classified in the phylum Proteobacteria. Cronobacter muytjensii was the most abundant species characterized in the whole body and gut of E. coreanus, and the unclassified species in the genera Brevundimonas and Lactobacillus were relatively more abundant in the head and carcass. In addition, no Wolbachia-like bacteria were detected, whereas bacteria like Francisella tularensis subsp. Holarctica OSU18 and unclassified Rickettsiella were first identified in ant lion E. coreanus.

Abstract
PURPOSE To evaluate the accuracy of diffusion-weighted imaging (DWI) in comparison to contrast-enhanced, fat-suppressed T1 -weighted imaging (CET1WI) in detecting acute optic neuritis (ON). MATERIALS AND METHODS The clinical data and magnetic resonance imaging (MRI) findings of 42 patients who presented with decreased vision were retrospectively reviewed. Both 3.0T MRI DWI and CET1WI orbital imaging studies were performed. Two neuroradiologists independently evaluated the DWI and CET1WI. The sensitivity, specificity, and accuracy of the DWI and CET1WI were individually calculated using the clinical diagnosis as the reference standard. The interobserver and intraobserver reliability of DWI and CET1WI were assessed by using a weighted Cohen's kappa (κ) test; a value of P < 0.05 was set as the threshold for statistical significance. RESULTS Of the 42 patients, 34 patients (41 nerves) had clinically confirmed acute ON, two had ischemic optic neuropathy, and three had chronic recurrent ON. The sensitivities of DWI and CET1WI for acute ON were 82.9-82.9% and 68.3-85.4%, respectively; the specificities were 81.4-83.7% and 79.1-93.0%, respectively; and the accuracies were 82.1-83.3% and 82.1-90.0%, respectively. The interobserver kappa values were 0.596-0.643 and 0.694-0.734 for DWI and CET1WI, respectively; the intraobserver kappa values were 0.809-0.905 and 0.834-0.924 for DWI and CET1WI, respectively (each P < 0.0001). CONCLUSION Given that its sensitivity and specificity are similar to those of dedicated CET1WI for acute ON, DWI can play an important complementary role in detecting acute ON, especially in atypical ON cases, and can provide a quantitative modality that can be used to evaluate axonal damage in the optic nerves.

Abstract
Tumor-associated calcium signal transducer 2 (TACSTD2), a calcium signal transducer, is universally expressed in stratified squamous epithelia of many organs, including skin, esophagus and cervix. Although TACSTD2, was reported to be overexpressed in many epithelial tumors, which has increased interest in using it as a molecular target for cancer therapy, the role of TACSTD2 in carcinogenesis of squamous cell carcinoma (SCC) is largely unclear and controversial. To explore the role of TACSTD2, temporal-spatial expression of TACSTD2 was analyzed in both normal and SCC tissues. Our data demonstrate that Tacstd2 expression and membrane localization are tightly associated with stratified epithelial homeostasis, while loss of TACSTD2 was identified in poorly differentiated SCC tissues collected from cervix, esophagus, head and neck. Gradual loss of TACSTD2 was correlated with stepwise progression of SCC. Consistent with these in vivo observations, our data show that inhibition of Tacstd2 expression significantly inhibited chemotherapeutic reagent-induced apoptosis, and TACSTD2 regulated apoptotic gene expression through P63 containing the transactivation domain (TAp63). These findings indicated that loss of TACSTD2 could promote SCC progression and treatment resistance through attenuating chemotherapeutic reagent-induced apoptosis through TAp63, and TACSTD2 could be used as a marker for pathological grading of SCC.

Abstract
Desmoglein 3 (Dsg3), the pemphigus vulgaris antigen, has recently been shown to be upregulated in squamous cell carcinoma (SCC) and has been identified as a good tumor-specific marker for clinical staging of cervical sentinel lymph nodes in head and neck SCC. However, little is known about its biological function in cancer. The actin-binding protein Ezrin and the activator protein 1 (AP-1) transcription factor are implicated in cancer progression and metastasis. Here, we report that Dsg3 regulates the activity of c-Jun/AP-1 as well as protein kinase C (PKC)-mediated phosphorylation of Ezrin-Thr567, which contributes to the accelerated motility of cancer cells. Ectopic expression of Dsg3 in cancer cell lines caused enhanced phosphorylation at Ezrin-Thr567 with concomitant augmented membrane protrusions, cell spreading and invasive phenotype. We showed that Dsg3 formed a complex with Ezrin at the plasma membrane that was required for its proper function of interacting with F-actin and CD44 as Dsg3 knockdown impaired these associations. The increased Ezrin phosphorylation in Dsg3-overexpressing cells could be abrogated substantially by various pharmacological inhibitors for Ser/Thr kinases, including PKC and Rho kinase that are known to activate Ezrin. Furthermore, a marked increase in c-Jun S63 phosphorylation, among others, was found in Dsg3-overexpressing cells and the activation of c-Jun/AP-1 was further supported by a luciferase reporter assay. Taken together, our study identifies a novel Dsg3-mediated c-Jun/AP-1 regulatory mechanism and PKC-dependent Ezrin phosphorylation that could be responsible for Dsg3-associated cancer metastasis.

Abstract
Objective: To assess the effect of cardioselective b-blockers on pulmonary function in patients with chronic obstructive pulmonary disease (COPD). Methods: The Embase and MEDLINE™ databases and the Cochrane Controlled Trials Register were searched comprehensively to identify all relevant clinical trials in humans published between January 1966 and May 2011. Randomized, blinded, placebo-controlled trials that studied the effects of cardioselective ß-blockers on the forced expiratory volume in 1 s (FEV1) and the responsiveness of the FEV1 to ß-agonist administration in patients with COPD were included in the analysis. Results: Five studies were identified: four of these assessed both cardioselective and nonselective ß-blockers; one assessed only cardioselective ß-blockers. The FEV1 was shown to decrease by 0.14 l with nonselective ß-blockers and by 0.03 l with cardioselective ß-blockers. The responsive -ness of the FEV1 to ß-agonist administration decreased significantly by 13.42% after nonselective ß-blockers, but did not change significantly after cardioselective -blocker administration. Conclusion: This meta-analysis suggests that the use of β-blockers, especially cardioselective β-blockers, should not be contraindicated in patients with COPD.

Abstract
A plane wave model with nonuniform temperature distribution in the thin-disk crystal is developed to describe the dynamic behavior of an end-pumped Yb:YAG thin-disk laser. A set of couple-rate equations and 2D stationary heat-conduction equations are derived. The stable temperature distribution in the disk crystal is calculated using a numerical iterative method. The analytic expression is capable of dealing with more practical laser systems than previous works on this subject as it allows for nonuniform temperature distribution in the disk crystal. Based on these results, we examined laser output intensity as a function of pump intensity, dopant concentration, resonator coupler reflectivity, crystal thickness and temperature of cooling liquid.

Abstract
Delayed cerebral ischemia (DCI) is a major complication that afflicts approximately 30% of patients who suffer an aneursymal subarachnoid hemorrhage (SAH). DCI is often associated with neurological infarction, poor outcome and mortality. Though the pathogenesis of DCI is not yet clear, it is traditionally been attributed to angiographic vasospasm. Unfortunately, clinical trials based on this premise have mostly been disappointing, predominantly unable to prevent ischemic damage and improve patient outcome despite reducing angiographic vasospasm. More recently, increasing concern that vasospasm could not fully account for DCI development has incited novel proposals as to the pathogenesis of DCI. A general theme exists among these theories (microcirculatory constriction, cortical spreading depression, blood brain barrier breakdown, microthrombosis) in that a majority seems to revolve around dysfunction and changes to the microvasculature. This purpose of this review was then to juxtapose macrovascular and microvascular changes after SAH, and provide an overview of current and prospective treatments.
