Abstract
Downy mildew, caused by Plasmopara halstedii, is one of the most destructive diseases in cultivated sunflower (Helianthus annuus L.). The dominant resistance locus Pl(ARG) originates from silverleaf sunflower (H. argophyllus Torrey and Gray) and confers resistance to all known races of P. halstedii. We mapped Pl(ARG) on linkage group (LG) 1 of (cms)HA342 × ARG1575-2, a population consisting of 2,145 F(2) individuals. Further, we identified resistance gene candidates (RGCs) that cosegregated with Pl(ARG) as well as closely linked flanking markers. Markers from the target region were mapped with higher resolution in NDBLOS(sel) × KWS04, a population consisting of 2,780 F(2) individuals that does not segregate for Pl(ARG). A large-insert sunflower bacterial artificial chromosome (BAC) library was screened with overgo probes designed for markers RGC52 and RGC151, which cosegregated with Pl(ARG). Two RGC-containing BAC contigs were anchored to the Pl(ARG) region on LG 1.

Abstract
A new long-acting ceftiofur hydrochloride preparation was formulated and its physical properties, stability, and pharmacokinetics were investigated in this study. The prepared ceftiofur hydrochloride suspension demonstrated a milk white consistency, was easy to re-disperse and was stable in light, heat and humidity stability tests. Its other physical properties such as flowability, syringeability, settling volume ratio, particle size and distribution were perfectly consistent with the standard of Ministry of Agriculture of the People's Republic of China. After intramuscular administration of a single dose in swine (5 mg/kg B.W.), the drug concentration-time data in plasma were well fitted using the two-compartment open model. Compared with the ceftiofur hydrochloride preparation (EXCENEL) from Pfizer, the peak concentration (C(max)) in plasma was decreased by 2.34 times (P < 0.001), the half-life of elimination phase (T(1/2beta)) was 1.65 times longer (P < 0.001), and the therapeutic level of ceftiofur above the lowest effective plasma concentration of 0.2 microg/mL (T > 0.2) was prolonged from 87.20 h to 135.36 h (P < 0.001). The ceftiofur hydrochloride suspension prepared in this study provides therapeutically effective plasma concentrations for a longer duration, which make it more effective and more convenient to use in the treatment of respiratory diseases that require the maintenance of therapeutic plasma concentrations over a long duration.

Abstract
Assessments of the behaviour of (99)Tc in terrestrial environments necessitate predicting soil-to-plant transfer. An experiment with 116 plant taxa showed that (99)Tc transfer to plants was positively related to plant dry weight but negatively related to % dry matter and age at exposure. Activities of (99)Tc analysed by hierarchical ANOVA coded with an angiosperm phylogeny revealed significant effects, with 55% of the variance between species explained at the Ordinal level and above. Monocots had significantly lower transfer of (99)Tc than Eudicots, within which Caryophyllales > Solanales > Malvales > Brassicales > Asterales > Fabales. There was a significant phylogenetic signal in soil-to-plant transfer of (99)Tc. This phylogenetic signal is used to suggest that, for example, a nominal Tc Transfer Factor of 5 could be adjusted to 2.3 for Monocots and 5.3 for Eudicots.

Abstract
Cytokines are crucial in activation of the cell-mediated immunity required for eliminating pathogens and controlling intracellular growth of Mycobacterium tuberculosis (TB). Genetic variants in the IL12-IFNG axis are hypothesized to be involved in the development and progression of TB. Genetic polymorphisms of rs2243115 and rs568408 in IL12A, rs3212227 in IL12B and rs2430561 in IFNG(+874) were detected in 522 pulmonary TB cases and 527 controls recruited from Yangzhong and Wujin County of China. It was found that genetic variants TG/GG of rs2243115(IL12A) were associated with a decreased risk of TB, with odds ratio (95% confidence interval) of 0.70 (0.49-0.99), whereas variant genotypes AT/TT of rs2430561(IFNG) conferred 82% less risk for treatment failure, with a hazard ratio of 0.18 (95% confidence interval 0.04-0.73). Cumulative effects analysis revealed that the risk of TB increased significantly with the number of unfavorable genotypes in IL12 genes. Furthermore, MDR analysis showed potential higher-order gene-gene and gene-environment interactions and indicated different outcomes based on distinct genotype profiles. Results from this study demonstrate that genetic polymorphisms of the IL12-IFNG pathway may individually or jointly contribute to the susceptibility to and prognosis of pulmonary TB.

Abstract
Gene encoding sulphur amino acid-rich protein (HNP) and rol genes were transferred into Medicago sativa L (alfalfa) mediated by Agrobacterium tumafeciens. Regeneration of transgenic plants was induced successfully from hairy root tissue of cotyledon in alfalfa. Cotyledon tissues were an ideally transformed recipient. There was a negative correlation between age of hairy roots and embryogenesis frequency in alfalfa. Production of co-transformed plants with greater yield and super quality was important for development of new alfalfa varieties.

Abstract
Giant Meckel's diverticulum is rare and usually presents in childhood with haemorrhage or bowel obstruction. Bleeding results from the presence of ectopic gastric mucosa causing peptic ulceration of adjacent mucosa. We discuss the case of a 21-year-old man with a giant Meckel's diverticulum who presented with rectal bleeding. A Meckel's scan was negative and histology following surgical excision ruled out the presence of ectopic gastric mucosa. There was however evidence of chronic inflammation and small bowel mucosal ulceration. We hypothesize that this arose from ischaemia and pressure necrosis because of the large size of the diverticulum and chronic distension by food debris. This case highlights the difficulties in investigating anaemia in young adults despite modern imaging techniques.

Abstract
3040 Background: ALT-801 is recombinant human interleukin-2 (IL-2) genetically fused to a single-chain T-cell receptor specific to a peptide antigen of human p53 presented in the context of HLA-A2 positivity. In tumor xenografts in animal models, this fusion protein demonstrated potent and targeted antitumor activity. Methods: A phase I/IIa multicenter clinical study was initiated to assess safety and clinical response of ALT-801 in patients with various metastatic malignancies. Patients screened positively for HLA-A2 and tumors expressed p53 peptide/HLA-A2 complex. In this dose escalation trial, patients received ALT-801 as a daily intravenous infusion for 4 days followed by a 10-day rest period and 4 additional daily doses. Results: Data from three dosing cohorts (0.015, 0.04, and 0.08 mg/kg/dose) indicate that ALT-801 is well-tolerated up to 0.04 mg/kg/dose. The half-life of ALT-801 is 2.5–4 hours per pharmacokinetic analysis, depending on the dose. Even at the 0.015 mg/kg level, there were sufficient concentrations of ALT-801 in the patients’ serum to fully activate cell lytic activity in vitro. Treatment with ALT-801 also led to immune activation in patients as demonstrated by elevated serum IFN-γ levels as well as an increase in IFN-γ-producing immune cells in patients’ blood. Interestingly, serum TNF-α, a major inducer of hypotension in patients receiving high-dose IL-2 treatment, was not induced in patients receiving ALT-801. Evidence of antitumor activity (i.e., stable disease, tumor shrinkage) was observed in some patients after one or two courses of ALT-801. Conclusions: At a dose of 0.04 mg/kg, ALT-801 is a well-tolerated agent that generated a vigorous immune response and demonstrated clinical efficacy in a group of patients with various metastatic malignancies. An expansion cohort of patients is in progress at 0.04 mg/kg. [Table: see text]

Abstract
The distributions of the composition and the strain in the Ge(Si)/Si(001) coherent islands grown by molecular-beam epitaxy are investigated by digital analysis of high resolution transmission electron microscopy (HRTEM) micrographs. Local composition and strain are obtained from the measurement of the lattice displacement based on the Poisson's formula and Vegard's law. The analysis suggests that the islands have high Ge content at the island's central region. The island is partially relaxed by the substrate deformation and strain concentrated around the edge of islands. The alloying of the islands was found due to the Si surface diffusion.

Abstract
BACKGROUND Smoking remains very common in Chinese men, and the economic burden caused by cigarette consumption on smokers and their families may be substantial. Using a large nationally representative household survey, the third National Health Services Survey (NHSS, 2003), we estimated the economic impact of smoking on households. METHODS Smoking status of all household members (over 15 years) was collected by interview for the NHSS, and households classified into one of seven categories based on their smoking status. Information on household income and expenditure, and use of health services was also obtained. We assessed both the "direct" costs (reducing funds available for spending on other commodities such as food, education, medical care, etc, using a fractional logit model), and "indirect costs" (increasing medical expenditures, using a log-linear model). RESULTS Every five packets of cigarettes consumed per capita per month reduces household spending on other commodities, most notably on education (by about 17 yuan per capita per annum) and medical care (11 yuan). The effects are greatest among low-income rural households. Households with quitters spend substantially more on medical care than never-smoking households (64 yuan for households with two or more quitters). CONCLUSIONS If a household member smokes, there is less money available for commodities such as education and medical care. Medical care expenditure is substantially higher among households with quitters, as ill-health is the main reason for quitting smoking in China. Smoking impoverishes a substantial number of poorer rural households.
