Flavonoid glycosides are metabolized byintestinal bacteria, giving rise to a wide range of phenolicacids that may exert systemic effects in the body. Themicrobial metabolism of flavonoids extracted from theleaves of Diospyros kaki (FLDK) by intestinal bacteria wasinvestigated in vitro. High-performance liquid chromatography/linear trap quadrupole orbitrap mass spectrometrywas performed to analyze the metabolites of flavonoidsin vivo using Xcalibur2.1 software. The results showed thatthe levels of flavonoid glycosides and flavonoid aglyconesdecreased rapidly in the process of microbial metabolismby intestinal bacteria in vitro, and the metabolic rate maybe related to the concentration of intestinal bacteria in theculture solution. In vivo metabolites of FLDK weredetected in rat plasma and urine after oral administration ofFLDK. Eight flavonoids were identified in the urine, andthree were identified in the plasma; however, flavonoidaglycones were not found in the plasma.

Husk proportion (HP) and lignin content (LC) are two important traits of seed quality of B. napus. Efficient selection of these two traits is an important way to improve the seed quality in meal improvement. A set of recombinant inbred lines (RILs) of B. napus (GH06 × Zhongyou 821) was used for mapping QTLs of HP and LC in a two-year study in different environments. 509 markers (78 SSR markers, 66 RAPD markers and 365 SRAP markers) were mapped on 26 linkage groups with an average length of 73.96 cM. The map covered a total of 1923 cM, and the average distance between two adjacent markers was 3.78 cM. Analysis of variance of LC and HP indicated that. LC might not be significantly affected by environment (F = 2.96 < 3.02) and HP might be affected by genotype × environment interactions. A total of 15 significant QTLs were detected in eight linkage groups with a LOD threshold value of 2.5 (LR ≥ 11.5) by CIM, explaining 4.99-16.14% of phenotype variation. Some QTLs of LC and HP were detected in near regions of the same linkage groups, such as qLCBB05-6-1 and qLCWZ06-6-1, qLCBB05-10-2 and qLCBB06-10-1 and qLCWZ06-10-2, qHPBB05-9-3 and qHPBB06-9-1, qHPBB05-10-4 and qHPBB06-10-2 and qHPBB06-10-3 and qHPWZ06-10-1. This study indicates that the repeatedly detected QTLs of LC and HP might be major-effect QTLs of LC and HP.

Background: MicroRNAs are noncoding RNA molecules that posttranscriptionally regulate gene expression. The aim of this study was to determine the role of microRNA-21 in cholangiocarcinomas and its relationship to cholangiocarcinoma RBE cell capacity for invasion and metastasis. Methods: MicroRNA-21 expression was investigated in 41 cases of cholangiocarcinoma samples by in situ hybridization and real-time PCR. Influence on cholangiocarcinoma cell line invasion and metastasis was analyzed with microRNA-21 transfected cells. In addition, regulation of reversion-inducing-cysteine-rich protein with kazal motifs (RECK) by microRNA-21 was elucidated to identify mechanisms. Results: In situ hybridization and real-time quantitative PCR results for patients with lymph node metastasis or perineural invasion showed significantly high expression of microRNA-21 (P<0.05). There was a dramatic decrease in cholangiocarcinoma cell line invasion and metastasis ability after microRNA-21 knockdown (P<0.05). However, overexpression significantly increased invasion and metastasis (P<0.05). Real-time PCR and Western-blot analysis showed that microRNA-21 could potentially inhibit RECK expression in RBE cells. Survival analysis showed that patients with higher expression levels of microRNA-21 more often had a poor prognosis (P<0.05). Conclusions: MicroRNA-21 may play an important role in cholangiocarcinoma invasion and metastasis, suggesting that MicroRNA-21 should be further evaluated as a biomarker for predicting cholangiocarcinoma prognosis.

The current study presents the synthesis and characterization of magnetic silica nanocomposites(MSNCs) decorated with Pluronic F127. The nanocomposites were loaded with doxorubicin (DOX) forhepatocellular carcinoma (HCC) therapy. The X-ray diffraction (XRD) patterns proved that the nanocompositeswere crystalline with diffraction peaks at 2h = 35.44 corresponding to (311) plane of Fe3O4. Thein vitro test demonstrated cell viability of above 90% revealing that MSNCs-F127 were biocompatible andnontoxic to the HEK293T and HepG2 cell lines; however, the MSNCs-F127-DOX formulations exhibited asignificant therapeutic effect against HepG2 cells. A pH-responsive drug release was detected, showing aHiguchi kinetic model at acidic and physiological conditions which demonstrated the best correlationcoefficient with R2 values of 0.969, and 0.932, respectively. The highest level of cell inhibitory rate, necrosis,and apoptosis in mice treated with MSNCs-F127-DOX was achieved by in vivo experiment, hematoxylinand eosin (H&E), and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL)staining. The in vivo experiment revealed a significant tumor inhibition after treatment with MSNCs-F127-DOX. The prepared MSNCs-F127-DOX formulations could be utilized as an innovative drug deliverysystem (DDS) for anticancer therapy for several cancer types.

A 0.18-μm CMOS 3-Gb/s equalizer with an adaptive swing controller is presented for 4K2K large display panels to compensate a 24-dB channel loss. Employing the output-swing control technique, we propose the adaptive loop for the equalizer to improve adaptation accuracy without degrading the boost tuning and input swing ranges. Besides, cascading two bandpass filters (BPF) measured energy in a narrow range is much more accuracy than conventional highpass filters (HPF). The measured jitter of 3-Gb/s and 1.5-Gb/s data are 0.23-UI and 0.356-UI for 1.23-m FR4 board, respectively. The core area occupies 0.12-㎟ and the power consumption is 27-mW at 3 Gb/s from a 1.8-V supply.

Hepatocellular carcinoma (HCC) is the most prevalent type of liver cancer, accounting for about 75% of allliver cancers. It is the third most common basis for cancer mortality worldwide, and unfortunately, itstreatment is often limited by the shortage of appropriate therapeutic options and side effects causedby the current treatment methods. To overcome this, doxorubicin (DOX)-loaded pH-/thermoresponsivemagnetic mesoporous nanocarriers were formulated and evaluated for their in vitro anticanceractivity against HCC. These nanocarriers consist of iron oxide (IO) nanoparticles conjugated withSBA-15 (S15) and Pluronic F127 (PF) to form IOS15 nanocomposites and IOS15@PF nanocarriers. The preparednanocarriers were superparamagnetic with saturation magnetizations of IOS15 and IOS15@PFbeing 76.3 and 72.1 emu/g, respectively. Small-angle neutron/X-ray scattering (SANS/SAXS) studiesshowed that the developed nanocarriers are temperature-sensitive and possess hexagonally arrangedstructures. Cell viability studies demonstrated that IOS15@PF@DOX nanocomplexes induced more apoptosisor necrosis. A temperature (69% release after 48 h)- and pH (70% release after 48 h)-dependent DOXrelease was observed, whereby more DOX was released at a high temperature of 42 C and pH value of5.4. Thus, the developed nanocarriers possess great potential for use in the targeted delivery of conventionalchemotherapeutic drugs with enhanced efficiency.
Online damage detection using pair cointegration method of time-varying displacement
Cui Zhou,Hong-Nan Li,Dong-Sheng Li,You-Xin Lin,Ting-Hua Yi 국제구조공학회 2013 Smart Structures and Systems, An International Jou Vol.12 No.3
Environmental and operational variables are inevitable concerns by researchers and engineers when implementing the damage detection algorithm in practical projects, because the change of structural behavior could be masked by the conditions in a large extent. Thus, reliable damage detection methods should have a virtue of immunity from environmental and operational variables. In this paper, the pair cointegration method was presented as a novel way to remove the effect of environmental variables. At the beginning, the concept and procedure of this approach were introduced, and then the theoretical formulation and numerical simulations were put forward to illustrate the feasibility. The jump exceeding the control limit in the residual indicates the occurrence of damage, while the direction and magnitude imply the most potential damage location. In addition, the simulation results show that the proposed method has strong ability to resist the noise.

The hot deformation behavior of pre-forged AZ80 magnesium alloy is investigated by the isothermal compression tests attemperatures of 523&amp;ndash;683 K and strain rates of 0.0001&amp;ndash;0.1 s&amp;minus;1, and analyzed by the processing maps for guiding isothermaldie forging. Flow localization and even cracking occurs at low temperatures and high strain rates, where shear deformationdegree shows a positive correlation with the &amp;#55349;&amp;#57097;( &amp;#775;&amp;#55349;&amp;#57088; ) value. Two stability regions with high efficiency is found out by theprocessing maps. At common stability region with high temperatures and low strain rates, peak power dissipation efficiencydoes not represent optimum deformation condition as reported in other materials. A Z parameter criterion is introduced forparameters optimization. javascript:void(0); a new stability domain of 523&amp;ndash;590 K and 0.0001&amp;ndash;0.01 s&amp;minus;1 is observed, which istypical for fine microstructure composed of equiaxed clean &amp;alpha;-Mg grains and big particles both about 1 &amp;mu;m (573 K/0.01 s&amp;minus;1).Super plasticity is speculated to occur at that condition.
