Abstract
We report the growth of single-crystalline Bi(2)Se(3) nanoribbons with lengths up to several millimeters via a catalyst-free physical vapor deposition method. Scanning transmission electron microscopy analysis reveals that the nanoribbons grow along the (112̅0) direction. We obtain a detailed characterization of the electronic structure of the Bi(2)Se(3) nanoribbons from measurements of Shubnikov-de Haas (SdH) quantum oscillations. Angular dependent magneto-transport measurements reveal a dominant two-dimensional contribution originating from surface states. The catalyst-free synthesis yields high-purity nanocrystals enabling the observation of a large number of SdH oscillation periods and allowing for an accurate determination of the π-Berry phase, one of the key features of Dirac fermions in topological insulators. The long-length nanoribbons open the possibility for fabricating multiple nanoelectronic devices on a single nanoribbon.

Abstract
Heterosexual transmission of HIV through contact with female sex workers (FSWs) is a growing concern for the HIV/AIDS epidemic in China. Using consecutive cross-sectional surveys, we examined the prevalence of HIV and sexually transmitted infections (STIs), risk behaviours, HIV knowledge and the utilization of intervention services among FSWs in Shandong Province. Of 3460 participants, half reported ever having STI-related symptoms, 57.8% had ≥7 clients in the last week, half reported inconsistent use of condoms with clients and 11.2% reported ever using illicit drugs. Consistent use of condoms with clients was associated with higher education, being 20-24 years of age, being recruited from hotels, having ever received free condoms and was inversely associated with STI-related symptoms. HIV-related knowledge was associated with higher education, ever testing for HIV and inversely associated with self-reported STI-related symptoms. The low rates of condom use, high number and frequent turnover of clients, high prevalence of self-reported STIs and drug use highlight the urgency for more effective intervention in these FSWs.

Abstract
It is hypothesized that "cancer stem cells" are responsible for the resistance to chemotherapy of cancer cells in ovarian cancers. The objective of the studies was to explore if the stem cell biomarkers could be used to predict the tumor chemotherapy-resistance in serous ovarian cancer patients. Expression of two putative stem cell markers CD133 and nestin, and vascular epithelial growth factor (VEGF) and epidermal growth factor receptor (EGFR) were detected in 123 cases of advanced serous ovarian cancer specimens by immunohistochemistry. To estimate intra-tumoral microvessel density (MVD), CD34 immunostaining was also performed. CD133 and nestin were defined to be positive in 35.0% and 32.5% of the serous ovarian carcinoma tissues, respectively. It was observed that overexpression of nestin but not CD133 was associated with the cisplatin-based chemotherapy resistance and shorter overall survival of the patients, and nestin was found to be an independent prognostic factor. Moreover, positive nestin expression also correlated to increased expression of EGFR and VEGF, and elevated MVD in tumors. The results of this study suggest that serous ovarian cancers with high expression level of nestin represent an aggressive malignant phenotype associated with poor prognosis, and treatment targeted the nestin positive cancer cells might be a promising therapeutic strategy for this subgroups.

Abstract
The Pib gene in rice confers resistance to a wide range of races of the rice blast pathogen, Magnaporthe oryzae, including race IE1k that overcomes Pita, another broad-spectrum resistance gene. In this study, the presence of Pib was determined in 164 rice germplasm accessions from a core subset of the National Small Grains Collection utilizing DNA markers and pathogenicity assays. The presence of Pib was evaluated with two simple sequence repeat (SSR) markers and a dominant marker (Pib-dom) derived from the Pib gene sequence. Pathogenicity assays using two avirulent races (IE1k and IB1) and a virulent race (IB54) were performed to verify the resistance responses of accessions. Of the 164 accessions evaluated, 109 contained the Pib gene as determined using both SSR markers and pathogenicity assays, albeit different haplotypes were detected. The remaining 52 germplasm accessions were different in their responses to the blast races IB54, IE1k, and IB1, thus indicating the presence of R gene(s) other than Pib. The accessions characterized in this study could be used for marker-assisted breeding to improve blast resistance in indica and japonica cultivars worldwide.

Abstract
Brca1 deficiency leads to the development of breast cancer. We previously found that Brca1 deficiency activates the Akt oncogenic pathway. Reduced expression of Brca1 was highly correlated with increased activated Akt in human breast cancer samples. Furthermore, activation of Akt1 was involved in Brca1-deficiency-mediated tumorigenesis in mice. Defective homologous recombination (HR) is thought to be a major contributor to tumorigenesis in Brca1 deficiency. Here, we show that Akt1 promotes chromosome instability in Brca1-deficent cells. DNA breaks in Brca1-deficent cells are aberrantly joined into complex chromosome rearrangements by a process dependent on Akt1. Depletion of Akt1 increases HR in Brca1-mutant cells, which is rescued by expression of wild-type, but not mutant Akt1 with deletion of Brca1-binding domain. Mechanistically, activated Akt1 in Brca1-deficient cells impairs Chk1 nuclear localization and subsequently disrupts interaction of Chk1 and Rad51 leading to HR defects. Our results indicate that Brca1 deficiency might activate Akt1 contributing to tumorigenesis through regulation of the Chk1-Rad51 signaling.

Abstract
Various combinations of heat time and relative humidity (RH) were tested for their ability to kill Pseudomonas syringae pv actinidiae (Psa) the cause of kiwifruit canker on freshly harvested anthers artificially contaminated with this bacterium Pollen viability and Psa survival were tested after treatment Although short durations at high temperatures and high RH did kill Psa these treatments were also lethal to pollen When RH was reduced the time before pollen viability was lost increased but Psa survival was also enhanced The most promising treatment was 35C at a RH of 50 or less at which pollen viability was not affected even after 20 h but Psa did not survive when applied at 106 cfu/ml Modelling suggests that extending the time of treatment would kill higher concentrations of Psa The mechanism for Psa death at 35C is probably by a combination of heat and desiccation

Abstract
AIM This study documents our experience with the use of ECMO in adult cardiac transplantation. Furthermore, in an attempt to improve outcomes of donor hearts with long ischemic times (LITs) we evaluated the efficacy of a strategy based on intraoperative ECMO (i-ECMO) circuit extended into postoperative cardiopulmonary support. METHODS From February 2005 to September 2009, 11 patients (i-ECMO group) receiving allografts with LITs >7 hours underwent intraoperative ECMO circuit strategy with routine extension of ECMO into postoperative period. Eleven contemporary patients (s-CPB group) received ECMO support after standard CPB at the various intervals after the transplantation as a salvage therapy. RESULTS Overall weaning rate was 86.4%; overall 30-day and 1-year survival rates were 81.8% and 72.7%, respectively. There was no difference in mortality between the two groups. Length of stay in the intensive care unit, the requirement for packed red blood cells administration and the total in-hospital cost were significantly reduced in i-ECMO group patients (P<0.05). CONCLUSION The salvage of failing cardiac allograft with ECMO allows effective stabilization of the hemodynamic and leads toward myocardial recovery. Extending ECMO into postoperative period provides early, continues and effective support for donor hearts with LITs and maximizes the use of such marginal organs.

Abstract
The breast cancer susceptibility gene 1 (Brca1) has a key role in both hereditary and sporadic mammary tumorigenesis. However, the reasons why Brca1-deficiency leads to the development of cancer are not clearly understood. Activation of Akt kinase is one of the most common molecular alterations associated with human malignancy. Increased Akt kinase activity has been reported in most breast cancers. We previously found that downregulation of Brca1 expression or mutations of the Brca1 gene activate the Akt oncogenic pathway. To further investigate the role of Brca1/Akt in tumorigenesis, we analyzed Brca1/Akt expression in human breast cancer samples and found that reduced expression of Brca1 was highly correlated with increased phosphorylation of Akt. Consistent with the clinical data, knockdown of Akt1 by short-hairpin RNA inhibited cellular proliferation of Brca1 mutant cells. Importantly, depletion of Akt1 significantly reduced tumor formation induced by Brca1-deficiency in mice. The third generation inhibitor of mammalian target of rapamycin (mTOR), Palomid 529, significantly suppressed Brca1-deficient tumor growth in mice through inhibition of both Akt and mTOR signaling. Our results indicate that activation of Akt is involved in Brca1-deficiency mediated tumorigenesis and that the mTOR pathway can be used as a novel target for treatment of Brca1-deficient cancers.

Abstract
We isolated a novel strain of Alphaproteobacteria from a patient, who had medical history of chronic rhinitis for more than twenty years and recently experienced local skin abscess and ulcer. He eventually died of multiple organ failure due to multi-antibiotics resistance. We identified the microorganism by 16SrRNA sequencing and found that it belonged to the genus Rhodoplanes. It was named as Rhodoplanes sp. strain ZLJ-0. It is resumed that Rhodoplanes sp. strain ZLJ-0 might be an emerging human pathogen involving in unknown febrile conditions and could cause local infection of any tissues or organs. Differential diagnosis of febrile patients should be conducted in clinical practice and research on emerging pathogens of Alphaproteobacteria should be performed to determine the epidemiology, clinical symptoms and pathogenic features of these pathogens.
