The purpose of this study was to estimate patient doses during coronary angiography (CA) and different complex percutaneous transluminal coronary angioplasty (PTCA) procedures in China. Consecutive 290 patients (90 CA, 200 PTCA) with known or suspected coronary artery disease were enrolled prospectively into six groups. Differences in patient doses among(More)
Most biomass pretreatment processes for sugar production are run at low-solid concentration (<10 wt.%). Subcritical carbon dioxide (CO2) could provide a more sustainable pretreatment medium while using relative high-solid contents (15 wt.%). The effects of subcritical CO2 pretreatment of sugarcane bagasse to the solid and glucan recoveries at different(More)
OBJECTIVE To re-evaluate the effects of different treatments to prevent from phlebitis induced by Chansu injection. METHOD Patients treated with Chansu injection were divided randomly into 4 groups with 50 per group, control group, the magnesium sulfate group, phentolaminum group, and anisodamine group. Patients in the control group only received the(More)
In the present work, nickel phosphide (Ni12P5) modified graphitic carbon nitride (g-C3N4) nanosheets were synthesized by a simple grinding method. The structural characterization clearly proved that Ni12P5 nanoparticles were well loaded on the surface of g-C3N4 nanosheets. The photocatalytic activity of the composites was tested by catalyzing the reduction(More)
Acetic acid ethanol-based organosolv pretreatment of sugar cane bagasse was performed to enhance enzymatic hydrolysis. The effect of different parameters (including temperature, reaction time, solvent concentration, and acid catalyst dose) on pretreatment prehydrolyzate and subsequent enzymatic digestibility was determined. During the pretreatment process,(More)
The different physical and chemical properties of lignin might have various effects on the enzymatic hydrolysis of lignocellulosic substrates. In this study, the influence of lignin on enzymatic digestibility of cellulose was assessed. Addition of 20% (4g/L) isolated enzymatic lignin (lignin 2 and 3) and kraft lignin (lignin 4) resulted in 5-20% drop of(More)
In this paper, we report a simple method to fabricate lead oxide nanorods by electrochemical reduction. In our experiment, the electrolyte was lead nitrate aqueous solution containing zirconium oxide chloride and titanium chloride solution. Stainless steel plate was employed as both cathode and substrate. The controlled current that was supplied by a direct(More)
For identifying the catalyst, we performed SAED analysis for the samples. Fig. S1(a) shows a CNF that is attached to a catalyst particle. This CNF and the Y-shaped CNFs are co-existed in the same samples. This TEM image and Fig. 3 were taken from the same TEM copper grid sample at the same time of TEM characterizations. According to SAED pattern, we can(More)
BACKGROUND Increasing evidence suggests that microRNAs are widely involved in cancer progression and metastasis. However, the specific role of miR-31 in papillary thyroid carcinoma (PTC) is still largely unknown. METHODS The level of miR-31 and HuR was detected in 30 pairedcancerous and noncancerous tissue samples using real time PCR. The impact of miR-31(More)
The construction of exceptionally robust and high-quality semiconductor-cocatalyst heterojunctions remains a grand challenge toward highly efficient and durable solar-to-fuel conversion. Herein, novel graphitic carbon nitride (g-C3N4) nanosheets decorated with multifunctional metallic Ni interface layers and amorphous NiS cocatalysts were fabricated via a(More)
