Ethylene controls cambium stem cell activity via promoting local auxin biosynthesis

Qin Yu, Chenxia Cheng, Xiaofeng Zhou, Yonghong Li, więcej

The vascular cambium is the main secondary meristem in plants that produces secondary phloem (outside) and xylem (inside) on opposing sides of the cambium. The phytohormone ethylene has been implicated in vascular cambium activity, but the regulatory network underlying ethylene‐mediated cambial activity remains to be elucidated. Here, we found that PETAL MOVEMENT‐RELATED PROTEIN1 (RhPMP1), an...

Disturbance of Bcl-2, Bax, Caspase-3, Ki-67 and C-myc expression in acute and subchronic exposure to benzo(a)pyrene in cervix

Meili Gao, Yongfei Li, Xiaoying Ji, Xiaochang Xue, więcej

Acta Histochemica > 2016 > 118 > 2 > 63-73

Epidemiological studies have demonstrated that cigarette smoking is an important cofactor or an independent risk factor for the development of cervical cancer. Benzo(a)pyrene (BaP) is one of the most potent tobacco smoke carcinogens in tobacco smoke. BaP induced DNA damage and over expression in p53 cervical tissue of mice as demonstrated in our previous study. Here we present the findings of exposure...

Experimental and Toxicologic Pathology > 2016 > 68 > 2-3 > 149-156

Benzo[a]pyrene [B(a)P], a representative substance of the polycyclic aromatic hydrocarbons, is an ubiquitous environmental contaminant. However, the mechanism of B(a)P neurotoxicity is still not clear. The aim of this study was to investigate the molecular mechanism by assay the expression of Bcl-2, C-myc, Ki-67 oncogene and p53, Bax, Caspase-3 proapoptotic gene in sub-regions of cerebral cortex and...

Novel slurry containing graphene oxide-grafted microencapsulated phase change material with enhanced thermo-physical properties and photo-thermal performance

Kunjie Yuan, Huichun Wang, Jian Liu, Xiaoming Fang, więcej

Solar Energy Materials and Solar Cells > 2015 > 143 > C > 29-37

In this work, a new microencapsulated phase change material, paraffin@ silica (SiO₂)/graphene oxide (GO), is prepared by two steps: engulfing paraffin with silica by in situ hydrolysis and poly condensation of tetraethoxysilane and the modification of the SiO₂ shell with GO. The paraffin@SiO₂/GO composite is composed of spherical capsules with diameters of ~20um. Raman spectrometer analysis verifies...

RT100/expand graphite composite phase change material with excellent structure stability, photo-thermal performance and good thermal reliability

Qi Zhang, Huichun Wang, Ziye Ling, Xiaoming Fang, więcej

Solar Energy Materials and Solar Cells > 2015 > 140 > C > 158-166

The combination of a phase change material (PCM) with expanded graphite (EG) is a simple and effective way to obtain a form-stable composite PCM with relatively high latent heat and enhanced thermal conductivity. In this paper, aiming at developing a high-performance PCM for medium-temperature latent heat storage applications, RT100, a mixture of paraffinic hydrocarbons with a melting point of around...

ChIP-seq predicted estrogen receptor biding sites in human breast cancer cell line MCF7

Qi Li, Huichun Wang, Leyang Yu, Jun Zhou, więcej

Tumor Biology > 2014 > 35 > 5 > 4779-4784

The aim of this study was to find estrogen receptor (ER) binding sites of estradiol (E2)-treated and control groups and discuss the roles of ER activation in the tumorigenesis and progression of various human cancers. The ER ChIP-seq data GSE19013 was downloaded from Gene Expression Omnibus database, including E2-treated data GSM470419 and control data GSM470418. MACS software was utilized to identify...

The uptake diversity of soil nitrogen nutrients by main plant species in Kobresia humilis alpine meadow on the Qinghai-Tibet Plateau

WenYing Wang, YongGui Ma, Jin Xu, HuiChun Wang, więcej

Science China Earth Sciences > 2012 > 55 > 10 > 1688-1695

We studied the uptake of ammonium, nitrate, and a variety of amino acids by alpine plant species in the Kobresia humilis alpine meadow ecosystem in situ. We examined the extent of niche separation in uptake of N source by different plant species in alpine communities, and investigated the contribution of symbiotically fixed N to the total N in alpine meadow. The results are (1) δ ¹⁵N natural abundance...

Synthesis of Sulfonated Carbon Nanocage and Its Performance as Solid Acid Catalyst

Pei Lin, Baolin Li, Jiangtao Li, Huichun Wang, więcej

Catalysis Letters > 2011 > 141 > 3 > 459-466

A carbon nanocage material (CKT) was first successfully sulfonated by introducing sulfophenyl groups on the surface of pore channels through benzenesulfonic acid-containing aryl radical in situ generated from the reaction of 4-aminobenzenesulfonic acid and isoamyl nitrite in water. The sulfonated carbon nanocage material (S-CKT) was characterized by Fourier transform infrared spectroscopy, transmission...

Catalytic oxidation of ethylene and ethane to formaldehyde by oxygen

Yinchuan Lou, Qinghong Zhang, Huichun Wang, Ye Wang

Journal of Catalysis > 2007 > 250 > 2 > 365-368

The selective oxidation of ethylene by oxygen produced formaldehyde with a single-pass yield of ∼30% at a temperature of 863 K and a contact time of 0.08 s g cm ⁻³ over a mesoporous silica (SBA-15)-supported molybdenum oxide catalyst. Oligomeric MoO _x species and polymeric MoO _x clusters were responsible for this reaction. The exploitation of a double-bed catalytic reaction...

SBA-15-supported molybdenum oxides as efficient catalysts for selective oxidation of ethane to formaldehyde and acetaldehyde by oxygen

Yinchuan Lou, Huichun Wang, Qinghong Zhang, Ye Wang

Journal of Catalysis > 2007 > 247 > 2 > 245-255

The selective oxidation of ethane was investigated over SBA-15-supported molybdenum oxide catalysts. Our characterizations suggest that the MoO _x species were dispersed mostly in mesoporous channels of SBA-15 at Mo content <9.5 wt%. At higher Mo content (15.4 and 20.1 wt%), MoO _x nanoparticles together with small amount of MoO ₃ crystallites were found. The growth of MoO...

The effect of land management on plant community composition, species diversity, and productivity of alpine Kobersia steppe meadow

Wenying Wang, Qiji Wang, Huichun Wang

Ecological Research > 2006 > 21 > 2 > 181-187

Grassland degradation is widespread and severe on the Tibet Plateau. To explore management approaches for sustainable development of degraded and restored ecosystems, we studied the effect of land degradation on species composition, species diversity, and vegetation productivity, and examined the relative influence of various rehabilitation practices (two seeding treatments and a non-seeded natural...
