Congenital absence of portal vein (CAPV) was a rare event in the past. However, the number of detected CAPV cases has increased in recent years because of advances in imaging techniques. Patients with CAPV present with portal hypertension (PH) or portosystemic encephalopathy (PSE), but these conditions rarely occur until the patients grow up or become old.(More)
Crazing is a failure mode of bulk polymers and occurs under predominant uniaxial tensile load when the bulk eventually forms denser ligaments (or fibrils) while preserving its continuity. The bridging of cracks by such fibrils is an importantmechanism for energy dissipation and toughening in thermoplastic polymers. However, craze phenomena are not observed(More)
Graphene oxide (GO) was functionalized and reduced simultaneously by a new reductant, 4-hydrazinobenzenesulfonic acid (HBS), with a one-step and environmentally friendly process. The hydrophilic sulfonic acid group in HBS was grafted onto the surface of GO through a covalent bond. The successful preparation of HBS reduced GO (HBS-rGO) was testified by(More)
In this paper, bulk polymeric composites with staggered orientation of carbon nanotubes (CNTs) in polymer matrix were prepared by means of a macro layer-by-layer (MLBL) method, while an alternating current (AC) electric field was applied for inducing alignment of the CNTs. Test results verified that there existed a relationship between conductive capacity(More)
An ideal carbon nanotube (CNT) network structure in poly(methyl methacrylate) (PMMA) can be attained by adjusting simultaneously both evolution of the CNTs alignment in methyl methacrylate (MMA) monomer under alternating current (AC) electric field and polymerization of MMA. Alignment of the CNTs in liquid media is time dependent and can be enhanced by(More)
3-Hydroxy-2-naphthoic acid hydrazide (HNH), a new reductant and modifier, was applied to reduce and modify graphene oxide (GO) in a one-step process. The obtained HNH reduced graphene oxide (HNH-rGO) was characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Raman spectroscopy, X-ray photoelectron spectroscopic (XPS) and Fourier(More)
BACKGROUND Hand, foot and mouth disease (HFMD) is an emerging public health problem in China, not only threatening the health of children, but also causing tremendous loss and burden to both families and society. The aim of this study was to characterize the epidemiology and clinical features of HFMD, and to understand the key factors affecting HFMD in the(More)
BACKGROUND Blood pressure control is an essential therapy for patients with acute type B aortic dissection (ABAD) and should be maintained throughout the entire treatment. Thus, vast majority current guidelines recommend control the blood pressure to lower than 140/90 mmHg. Theoretically, a much lower target may further decrease the risk of propagation of(More)
