OBJECTIVE Discuss the main points of diagnosis of cortriatrium; patient's color Doppler echocardiography (CDE), provide basis for clinical treatment. PATIENTS AND METHODS Inspect 12 cortriatrium cases with CDE, 10 cases with cardiovascular angiography, 12 patients were confirmed by operation. Operations were all carried out under the moderate hypothermia cardiopulmonary bypass with intracardi...

The aim of this prospective cohort study was to investigate the effect of head and neck positioning on cerebral perfusion during shoulder arthroscopy in the beach chair position. Regional cerebral tissue oxygen saturation (rSO2) was monitored intraoperatively using near-infrared spectroscopy on 51 consecutive patients undergoing arthroscopic shoulder surgery in the beach chair position. The hea...

A novel approach of Content Based Image Retrieval(CBIR), which combines color, texture and shape descriptors to represent the features of the image, is discussed in this paper. The proposed scheme is based on three noticeable algorithms: color distribution entropy(CDE), color level co-occurrence(CLCM) and invariant moments. CDE takes the correlation of the color spatial distribution in an image...

Clinical research data generated by a federation of collection mechanisms and systems often produces highly dissimilar data with varying quality. Poor data quality can result in the inefficient use of research data or can even require the repetition of the performed studies, a costly process. This work presents two tools for improving data quality of clinical research data relying on the Nation...

The asymmetric unit of the title compound, C(16)H(20)N(4), contains two half-mol-ecules, which are completed by crystallographic inversion symmetry. The pyridazine rings are conjugated and the cyclo-hexane rings adopt envelope conformations.

The Gas6/Axl pathway has been increasingly implicated in regeneration and tissue repair and, recently, in the control of innate immunity. In liver, we have demonstrated that Gas6 and its receptor Axl are expressed in macrophages, progenitor cells, and myofibroblasts and that Gas6 deficiency reduced inflammation and myofibroblast activation, causing delayed liver repair in response to acute inju...

Objective: The objective of this study is to explore the influence of combined femtosecond laser and phacoemulsification on postoperative curative effect and safety on cataract patients. Method: One hundred forty-five cataract patients (148 eyes) needing operation were selected and grouped by difference in operation method: control group, 72 patients (74 eyes) were treated with traditional phac...

An electron microscopic, immunocytochemical, and enzyme cytochemical analysis of the previously established oval cell lines OC/CDE 6 and OC/CDE 22 was performed to characterize the phenotype and differentiation patterns of long-term cultures of oval cells. It was found that alpha-fetoprotein, albumin, and cytokeratin 19 are present in all cultured cells. This indicates that oval cells constitut...

N. Toride, F. J. Leij, and M. Th. van Genuchten. The CXTFIT Code for Estimating Transport Parameters from Laboratory or Field Tracer Experiments, Version 2.0, Research Report No. 137, U. S. Salinity Laboratory, USDA, ARS, Riverside, CA. Successful predictions of the fate and transport of solutes in the subsurface hinges on the availability of accurate transport parameters. We modified and updat...

Abstract Calcined diatomaceous earth (CDE) with a maximum grain size of 143 ?m was used to partially replace 5 and 10% cement in ultra-high-performance concrete (UHPC) mixtures. The other materials producing the include Ordinary Portland Cement, iron ore powder, river sand sizes 112.5, 231, 766.2 ?m, respectively. Moreover, UHPC specimens designed water–cement ratio 0.2 superplasticizer 1.5% fr...
