1. miRNA-1180 suppresses HCC cell activities via TRAF1/NF-κB signaling pathway
Abstract The miRNA-1180 anti-cancer effects in hepatocellular carcinoma cell were studied. 33 hepatocellular carcinoma patients were collected. In cancer and adjacent normal tissue from patients, TRAF1 protein and miR-1180 expression was determined by HE staining, IHC and RT-PCR methods. In the cell experiments, HepG2 cells were divided into three groups: NC

2. DETERMINATION OF FOUR ARSENIC SPECIES IN ALGAE BY HIGH-PERFORMANCE LIQUID CHROMATOGRAPHY COUPLED WITH HYDRIDE GENERATION ATOMIC FLUORESCENCE SPECTROMETRY
A rapid method has been developed for the determination of silver arsenite As(III), dimethylated arsenic DMA, monomethylated arsenic MMA, and arsenate As(V) in algae sample using liquid chromatography coupled with hydride generation atomic fluorescence spectrometry (LC-HG-AFS). Types, flow rate and pH of mobile phase were optimized. Under the optimal conditi

4. Mancha areolada de Thanatephorus da seringueira na Amazônia: identificação filogenética e variação genética em populações do patógeno
RESUMO A mancha areolada de Thanatephorus é uma das doenças mais importantes da seringueira (Hevea brasiliensis) na Amazônia. Apesar disso, questão importante sobre o real posicionamento filogenético deste patógeno ainda não foi respondida. Neste estudo, nós analisamos os padrões de variação genética em seqüências da região ITS-5.8S do rDNA de

5. LC-UV method to assay raloxifene hydrochloride in rat plasma and its application to a pharmacokinetic study
A specific, precise, and accurate LC-UV method was developed and validated to assay raloxifene hydrochloride in rat plasma. Raloxifene was analyzed after liquid-liquid extraction and quantified by reversed phase liquid chromatography (C18 column) using acetonitrile and ammonium acetate buffer 0.05 M (pH 4.0) as mobile phase at a flow rate of 1 mL.min-1 and U

6. Atomization Characteristics of Droplet and Morphologies of Arc Sprayed Ni-Al Particles and Composition Coatings
Droplet atomization characteristics and its morphology in twin-wire arc sprayed (TWAS) Ni-Al were explored in depth. Both numerical model and theoretical method were built for calculating the process of the droplet deformation and breakup in air flow, which based on the standard k-ε model and the volume of fluid (VOF) dual-phase flow model. The atomization

7. Ischemic preconditioning delays the time of exhaustion in cycling performance during the early but not in the late phase
Abstract Aims: To investigate the early and late ischemic preconditioning (IPC) effect on the trained cyclists’ performance during incremental cycling test until exhaustion. Methods: Twenty-one male cyclists allocated to an IPC (2 x 5-min of blood flow occlusion at 50 mm Hg above systolic pressure followed + 5-min of deflation), SHAM (2 x 5-min at 20 m

8. MODEL PREDICTIVE CONTROL FOR PRODUCTION OF ULTRA-LOW SULFUR DIESEL IN A HYDROTREATING PROCESS
ABSTRACT There is a continual desire around the world to reduce the sulphur content of diesel fuel to ultra-low levels (below 10 ppm) due to environmental concerns and the intention of improving air quality and lowering harmful exhaust emissions of diesel engines. In this work, a hydrodesulfurization unit fed with multiple diesel streams was addressed using

10. Thermal profiles in pervious concrete during summer rain simulations
ABSTRACT Pervious concrete pavement systems may have many environmental benefits including the mitigation of heat island impacts. This mitigation is a complex combination of pervious concrete’s insulating capability and its ability to store water which may provide evaporative cooling. However, the introduction of water may also bring heat into the system,

12. Nutrient Biological Removal in an Up-flow Sludge Bed Reactor under Intermittent Aeration using Glycerol as the Sole Carbon Source
Abstract This work evaluated the feasibility of glycerol as the sole carbon source for nutrient biological removal in an intermittently aerated bioreactor. The reactor operation was divided into two phases: the first one aimed only at removing nitrogen; and the second one aimed at removing nitrogen and phosphorus. In the first operational phase, three C/N (C
