Abstract
During May of 2009, a new devastating disease was observed on pomegranate (Punica granatum L.) that caused losses estimated at 30% as surveyed by 10 orchards in Panzhihua-Xichang Region of Sichuan Province, Southwest China. Characteristic symptoms were yellow and wilting leaves. Initial symptoms only occurred on shoots, but later, leaves of the whole tree turned yellow and wilted, causing extensive defoliation and dieback and the xylem of the trunk turned brown to black with a star burst-like pattern. Finally, heavy infection resulted in the whole tree dying, causing severe yield losses. A fungus was consistently isolated from basal stems and roots of diseased plants. Single conidia were obtained and cultured on potato dextrose agar (PDA) and incubated at 25 ± 1°C with a 12-h light/dark photoperiod. Mycelium was initially hyaline and then rapidly became dark greenish brown. Two types of endoconidia were produced in 5 days. Barrel-shaped conidia were hyaline, 1-celled, and measured 7.3 to 9.4 × 11.6 to 13.2 μm. Cylindrical conidia were hyaline, 1-celled, and measured 9.2 to 29.6 × 3.1 to 6.8 μm. Aleurioconidia were brownish, thick walled, near globose, and measured 8.7 to 18.1 × 8.2 to 10.7 μm. Perithecia were dark brown to black, globose, measured 90.8 to 149.8 μm in diameter, and had a long thin neck, 254.4 to 533.8 μm long, through which ascospores exuded. Ascospores were small, hyaline, hat shaped, measured 3.7 to 6.5 × 3.1 to 5.7 μm, and accumulated in a sticky matrix at the tip of the ascomal neck. The fungus was identified as Ceratocystis fimbriata (anamorph Chalara sp.) (1). The internal transcribed spacer (ITS) region of rDNA was amplified with universal primers ITS4/ITS5 and sequenced (GenBank Accession No. HQ529711), and comparisons with GenBank showed 99% similarity with C. fimbriata on Colocasia esculenta from Brazil (Accession No. AM712448.1). Pathogenicity tests were conducted. Two-week-old seedlings of pomegranate cv. Qingpiruanzi, germinated in plastic containers in the greenhouse, were wounded with a needle to a depth of 0.5 mm at the base of the stem below the soil level and near the root system, and then inoculated by drenching the wounds with a spore suspension (105 conidia per ml). Control plants were inoculated with sterile water. There were four replicates for each treatment. The treated plants were incubated at 25 ± 1°C with 80 to 95% relative humidity under a 12-h light/dark photoperiod in a greenhouse. All inoculated plants wilted within 25 days after inoculation and C. fimbriata was reisolated. All control plants remained healthily. To our knowledge, this is the first finding of pomegranate wilt caused by C. fimbriata in Sichuan Province. This pathogen may pose a serious threat to pomegranate production in Sichuan where it is a major fruit tree. This pathogen has been previously reported in India (3) and Yunnan Province, China (2), but is not known elsewhere. References: (1) C. J. B. Engelbrecht and T. C. Harrington. Mycologia 97:57, 2005.

Abstract
Monodispersed Co nanoclusters have been grown on a graphene moiré on Ru(0001) at room temperature. Scanning tunneling microscopy measurements showed that the Co clusters nucleate at both the fcc and hcp regions. Co forms finely dispersed small three-dimensional (3D) clusters on graphene/Ru(0001), and a defined long-range ordering of Co nanoclusters with increasing coverage is not observed. The size distribution of the clusters is narrow and the size of the clusters is tunable. The absorbed Co begins to intercalate between the graphene layer and the Ru(0001) substrate when annealing the sample at temperatures up to about 473 K.

Abstract
Enamel biomineralization results in a release of protons into the enamel matrix, causing an acidification of the local microenvironment. This acidification, which may be enhanced by more rapid mineral deposition in the presence of fluoride, must be neutralized by the overlying ameloblasts. The electrogenic sodium bicarbonate co-transporter NBCe1 has been localized in mouse ameloblasts, and has been proposed to have a role in matrix pH regulation. In this study, transcript analysis by PCR showed NBCe1-A present in human ameloblasts, whereas mouse ameloblasts expressed NBCe1-B. In situ hybridization and qPCR in mouse and fetal human incisors showed that NBCe1 mRNA was up-regulated as ameloblasts differentiated. Ingestion of 50 ppm fluoride resulted in an up-regulation of NBCe1 mRNA in maturation-stage mouse ameloblasts in vivo, as compared with controls. NBCe1 expression was up-regulated by low pH, but not by fluoride, in human ameloblast-lineage cells in vitro. The up-regulation of NBCe1 in vivo as enamel maturation and mineralization progressed provides evidence that NBCe1 participates in pH modulation during enamel formation. Up-regulation of NBCe1 in fluorosed maturation ameloblasts in vivo, with no effect of fluoride in vitro, supports the hypothesis that fluoride-enhanced mineral deposition results in acidification of the mineralizing enamel matrix.

Abstract
Abstract
Objectives: Bone is one of the most common metastatic sites of breast cancer. Recent date from randomized clinical studies suggested that the use of bisphophonates affect bone metastasis and survival in early breast cancer patients. Results from some of these trials are encouraging but somewhat contradictory. We conducted a meta analyses to assess the effect of bisphosphonates on bone metastasis and survival in primary breast cancer patients.
Methods: Trials were retrieved by searching the PubMed database, Cochrane Library and major cancer scientific conferences up to January 2010. All tirals randomized patients to receive any bisphosphonate versus non-use or placebo. Hazard ratios (HR) and its 95% CIs for bone metastasis free survival and overall survival were estimated.
Results: 8 eligible trials including 6132 patients entered the analysis. 3049 patients were treated with bisphosphonates and 3083 received either placebo or no treatment. Compared with no use, bisphophonates in the adjuvant setting improved the overall survival (HR=0.808; 95%CI 0.708-0.923; P = 0.022). However, the reduction of bone metastasis was failure to be seen (HR = 1.011; 95% CI 0.996-1.027; P = 0.667). Conclusion: Our meta-analysis provides additional evidence that adjuvant breast cancer treastment with bisphosphonates brought a survival benefit. However, the result should be carefully interpreted for that the statistical significance was not consistent in the bone benefit. Results of new clinical trials were awaited.

Abstract
A novel 2-positional linked carbazole based β-diketone with methoxyl in the 7-position (EMOCTFBD), and its europium(III) ternary complex Eu(EMOCTFBD)(3)phen were synthesized via a dexterously designed indirect routine, where EMOCTFBD was 1-(9-ethyl-7-methoxyl-9H-carbazol-2-yl)-4,4,4-trifluorobutane-1,3-dione and phen was 1,10-phenanthroline. Eu(EMOCTFBD)(3)phen shows high thermal stability. The introduction of a methoxyl in the 7-position of the carbazole ring remarkably enhanced the excitation band intensity in the blue region, and the complex exhibited intense red emission under blue-light excitation. The lowest triplet state energy was measured and suggests the photoluminescence process as a ligand-sensitized luminescence process (antenna effect). A bright red-emitting diode was fabricated by coating the complex phosphor onto a ∼460 nm-emitting InGaN chip. All the results indicate that Eu(EMOCTFBD)(3)phen is an interesting red-emitting material excited by blue light, and therefore may be applied in many fields without UV radiation.

Abstract
The aim of this study was to construct a lentivirus vector that carries the human myxovirus-resistant A (MxA) anti-virus gene for efficiently infecting rooster spermatogonial stem cells (SSCs). A lentiviral vector carrying the enhanced green fluorescent protein (EGFP) and MxA fusion gene (EGFP-MxA) was constructed using TOPO technology in this study. Enhanced green fluorescent protein-MxA was inserted in the right orientation as determined by restriction enzyme digest. No gene recombination in the vector occurred. After infecting 293FT cells, EGFP-MxA fusion protein was expressed as granular green fluorescence characteristic of EGFP-MxA expression, suggesting that the TOPO expression vector was properly constructed and the fusion protein expressed correctly. The EGFP-MxA recombinant lentivirus was packaged by cotransfecting 293FT cells with EGFP-MxA and the packaging plasmids. We also purified SSCs from testicle tissues from 25-day-old roosters for infection with the EGFP-MxA recombinant virus. After infecting rooster SSCs with the recombinant virus for 72 h, EGFP-MxA expression was detected by EGFP expression. Enhanced green fluorescent protein-MxA expression in SSCs was further confirmed at the transcription level by RT-PCR and at the protein level by immunocytochemistry. Staining with Hoechst 33342 showed that infected SSCs differed from the sertoli cells. Similar to stem cells, SSCs were positive for alkaline phosphoric acid enzyme and for stage-specific embryonic antigen-1 stem cell factor. The results demonstrated that the recombinant virus made in our study can infect rooster SSCs efficiently to express the anti-virus protein MxA, establishing the basis of transferring MxA into SSCs to obtain virus-resistant, genetically-modified roosters.

Abstract
Similar evolution was obtained for the stable carbon isotope signatures delta (13)CH(4) and the model-predicted relative rate of aceticlastic methanogenesis during mesophilic methanization of municipal solid wastes. In batch incubations, the importance of aceticlastic and hydrogenotrophic methanogenesis changes in time. Initially, hydrogenotrophic methanogenesis dominated, but increasing population of Methanosarcina sp. enhances aceticlastic methanogenesis. Later, hydrogenotrophic methanogenesis intensified again. A mathematical model was developed to evaluate the relative contribution of hydrogenotrophic and aceticlastic pathways of methane generation during mesophilic batch anaerobic biodegradation of the French and the Chinese Municipal Solid Wastes (FMSW and CMSW). Taking into account molecular biology analysis reported earlier three groups of methanogens including strictly hydrogenotrophic methanogens, strictly aceticlastic methanogens (Methanosaeta sp.) and Methanosarcina sp., consuming both acetate and H(2)/H(2)CO(3) were considered in the model. The total organic and inorganic carbon concentrations, methane production volume, methane and carbon dioxide partial pressures values were used for the model calibration and validation. Methane isotopic composition (delta (13)CH(4)) evolution during the incubations was used to independently validate the model results. The model demonstrated that only the putrescible solid waste was totally converted to methane.
