Compared with conventional angiogram-guided procedure, intravascular imaging modalities give us a lot of useful information to make the procedure better. Intravascular imaging modalities give us the information about lesion characters, reference vessel diameter and the interaction between the stent strut and the plaque such as stent strut malapposition or plaquqe prolapse in real time during the procedure. We can change our strategy according to these information. Intravascular ultrasound (IVUS) is a most common intravasculr imaging modality during CAS in these days...

Rational heteroatom engineering is applied to develop high-performance electron-transporting naphthalenediimide copolymers. Top-gate field-effect transistors fabricated from selenophene-containing polymers achieve an ultrahigh electron mobility of 8.5 cm(2) V(-1) s(-1) and excellent air-stability. The results demonstrate that the incorporation of selenophene heterocycles into the polymers can improve film-forming ability, intermoleclar interaction, and carrier transport significantly.

Ultrafine-grained die-upset Nd-Fe-B magnets are of importance because they provide a wide researching space to redesign the textured structures. Here is presented a route to obtain a new die-upset magnet with substantially improved magnetic properties. After experiencing the optimized heat treatment, both the coercivity and remanent magnetization of the Dy-Cu press injected magnets increased substantially in comparison with those of the annealed reference magnets, which is distinct from the reported experimental results on heavy rare-earth diffusion...

OBJECTIVES: Adenoma detection rate (ADR) is a key colonoscopy quality indicator in Western clinical literature. Our low ADR prompted us to assess novel methods to improve performance. Western retrospective reports suggested that water exchange (WE) could increase ADR. However, most of these studies used pain score or intubation rate as the primary outcome. Here we test the hypothesis that WE significantly increases ADR among Chinese colonoscopists and design a prospective randomized controlled trial using ADR as our primary outcome...

Plasmonic structures couple oscillating electromagnetic fields to conduction electrons in noble metals and thereby can confine optical-frequency excitations at nanometre scales. This confinement both facilitates miniaturization of nanophotonic devices and makes their response highly sensitive to mechanical motion. Mechanically coupled plasmonic devices thus hold great promise as building blocks for next-generation reconfigurable optics and metasurfaces. However, a flexible approach for accurately batch-fabricating high-performance plasmomechanical devices is currently lacking...

INTRODUCTION: Cognitive remediation therapy (CRT) has been reported to positively affect neurocognitive processes among patients with schizophrenia; however, the degree to which changes in cognition is linked to improved clinical symptoms, remains poorly understood. The current study aimed to investigate whether cognitive gains were associated to improvements in negative symptoms' severity in patients with schizophrenia living in two Italian psychiatric facilities. METHODS: Patients with a diagnosis of schizophrenia were consecutively assigned to CRT (n = 33) and compared with an historical control group (n = 28)...

A meta-analysis was performed to examine the efficiency and safety of trastuzumab in patients with advanced gastric and gastroesophageal cancer (AGC). By searching multiple databases from 1990 to March 2016, all randomized controlled trials (RCTs) which compared the effect of trastuzumab-combined chemotherapy (TC) versus chemotherapy alone (CT) in gastric cancer would be included. Five RCTs with a total of 875 patients were included. Trastuzumab can improve the overall survival (OS) rate, progression-free survival (PFS), one-year survival rate, two-year survival rate and overall response rate (ORR) of patients with AGC...

Obstructive sleep apnoea syndrome (OSA) is a disease very frequently occurring in people with type 2 diabetes, that significantly increases cardiovascular morbidity and mortality. In a number of studies, OSA has been identified as an independent risk factor for the development of insulin resistance, glucose intolerance and type 2 diabetes mellitus. Disorders of glucose homeostasis in patients with OSA are probably mediated by chronic intermittent hypoxia and/or sleep fragmentation through activation of the sympathetic nervous system, the hypothalamic-pituitary-adrenal stress axis, pro-inflammatory paths or oxidative stress...

The most widely used method for isotope analysis at natural abundance is isotope ratio monitoring by Mass Spectrometry (irm-MS) which provides bulk isotopic composition in (2) H, (13) C, (15) N, (18) O or (34) S. However, in the 1980s, the direct access to Site-specific Natural Isotope Fractionation by Nuclear Magnetic Resonance (SNIF-NMR(TM) ) was immediately recognized as a powerful technique to authenticate the origin of natural or synthetic products. The initial - and still most popular - application consisted in detecting the chaptalization of wines by irm-(2) H NMR...

INTRODUCTION: Chiari malformation type-1 (CM-1) may be treated by intradural (ID) or extradural (ED) posterior fossa decompression, although the optimal approach is debated. The Chiari Severity Index (CSI) is a pre-operative metric to predict patient-defined improvement after CM-1 surgery. In this study, we evaluate the results of ID versus ED decompression and assess the external validity of the CSI. METHODS: We performed a retrospective cohort study of pediatric CM-1 patients undergoing decompression at a single academic children's hospital...
