Abstract
273 Background: G has been studied in combination with a variety of agents known to be active in cancer. G has a mild toxicity profile. GC is active in various advanced tumors. Splitting of C dose (D 1 + d8) is better tolerated and can be a good alternative to once a cycle in pts with advanced breast cancer. This phase II trial evaluates G (1000 mg/m2) C (35 mg/ m2) d1+8 repeated every 21 d in the 1st-line treatment of metastatic breast cancer (MBC). The primary objective of the study was to determine the objective tumor response rate (ORR) of 1st-line GC in patients with metastatic breast cancer.The one-stage design tested the null hypothesis that the true response rate for this population should be equal to 50% for efficacy. Overall survival (OS), time to progression (TTP) and toxicity were evaluated. Methods: 70 female MBC pts with the median age of 49.8 ys (range 29.6-80.0) were enrolled. Tumor assessment was performed every other cycle by standard criteria including CT or MRI. 67 pts received a total of 310 cycles GC, out of these 54 pts were evaluable for efficacy. Results: Complete and partial responses were observed in 7/54 (13.0%) and 19/54 (35.2%) evaluable pts, respectively with an overall response of 48.2%. Disease stabilization was noticed in 19/54 (35.2%) pts. Progression was observed in 5/54 (9.3%) pts. TTP was 33.9 weeks (95% CI, 23.9-48.0). OS was 84.0 weeks (95% CI, 58.6-119.3). 1-year overall survival rate was 68.4% (95% CI, 53.6-79.3%). Hematological toxicity G4 was neutropenia in 14.9% (10/67), and no G4 thrombocytopenia. Hypotension G4 (1.5%) was the only severe non-hematological toxicity. Conclusions: GC in the first-line treatment of MBC, demonstrated a substantial overall response rate and had a good toxicity profile. GC is a suitable option for first-line MBC in selected pts.

Abstract
Spin injection across the ferrimagnetic insulator (YIG)/normal metal (Au) interface was studied by ferromagnetic resonance. The spin mixing conductance was determined by comparing the Gilbert damping in bare YIG films with those covered by a Au/Fe/Au structure. The Fe layer in Au/Fe/Au acted as a spin sink as displayed by an increased Gilbert damping parameter α compared to that in the bare YIG. In particular, for the 9.0 nm YIG/2.0 nm Au/4.3 nm Fe/6.1 nm Au structure, the YIG and Fe films were coupled by an interlayer exchange coupling, and the exchange coupled YIG exhibited an increased Gilbert damping compared to the bare YIG. This relationship between static and dynamic coupling provides direct evidence for spin pumping. The transfer of spin momentum across the YIG interface is surprisingly efficient with the spin mixing conductance g(↑↓) ≃ 1.2 × 10(14) cm(-2).

Abstract
We report here the synthesis and characterization of novel diethynylbenzene-based liquid crystalline semiconductor (P1) for organic thin-film transistors (OTFTs). Compound P1 was synthesized by the Sonogashira coupling reaction between 2-bromo-5-(4-hexylthiophen-2-yl)thieno[3,2-b]thiophene and 1,4-bis(dodecyloxy)-2,5-diethynylbenzene. Top contact OTFTs were fabricated by spin casting with 2 wt% solution of P1 in chloroform and their best performance, which exhibited a hole mobility of 4.5 x 10(-5) cm2/Vs, was showed after annealing of the films at liquid crystalline temperature. Time-of-flight (TOF) mobility measured at liquid crystalline phase was observed to be 1.5 x 10(-6) cm2/Vs for both positive and negative carriers. These results indicate that the liquid crystallinity helps to improve the molecular packing and enhance charge mobility for P1. These advantages can be applicable to design and construct solution-processable OTFT materials for electronic applications.

Abstract
BACKGROUND To evaluate the efficacy and safety of oral and i.v. vinorelbine plus trastuzumab as first-line regimen in a patient-convenient application for human epidermal growth factor receptor 2 (HER2)-overexpressing patients with metastatic breast cancer. PATIENTS AND METHODS Forty-two women were enrolled in a multicenter study. The patients received i.v. vinorelbine at a dose of 25 mg/m(2) on day 1 followed by oral vinorelbine at a dose of 60 mg/m(2) on days 8 and 15 in a 3-week cycle. Standard dose trastuzumab was given at 3-week intervals. RESULTS Complete response was observed in 7 patients (18.9%) and partial response in 19 patients (51.4%), for an overall response rate of 70.3% [95% confidence interval (CI) 53.0-84.1]. The disease control rate reached 91.9% (95% CI 78.1-98.3). The median time to progression was 9.3 months, while median overall survival reached 35.6 months. Hematological and non-hematological toxic effects were acceptable with grade 3-4 leukopenia of 14% and neutropenia of 38%; cardiac toxicity did not reach the level of clinical relevance. CONCLUSION The combination of i.v. and oral vinorelbine plus trastuzumab demonstrates high activity and good tolerability in first-line treatment of HER2-overexpressing metastatic breast cancer. In addition, it offers convenience for the patients with only one i.v. treatment every 3 weeks.

Abstract
At high ambient temperatures, honeybees regulate head teriperature by evaporative cooling of regurgitated honeycrop contents. Thoracic temperature is secondarily stabilized as heat flows from thorax to head by means of passive conduction and physiological facilitation resulting from accelerated blood flow. The mechanism permits flight at the extraordinarily high ambient temperature of 46 degrees C without overheating the head and thorax despite prodigious amounts of heat produced as a by-product of flight metabolism. In contrast, at low ambient temperatures, thoracic rather than head temperature is regulated; no liquid is regurgitated, and the head is heated passively by conduction both in flight and while stationary.

Abstract
UNLABELLED The German paediatric surveillance unit (ESPED) was founded in 1992 with the objective to generate incidence data and to describe symptoms, diagnostic procedures, therapy and prevention for rare paediatric diseases requiring in hospital treatment. Every month the ESPED office sends a mailing card to the heads of all paediatric departments asking for the incident diagnosis of up to 12 conditions. In 2007 about 96% of the cards are returned. Each condition is represented by a principal investigator. Up till now surveillance of 52 conditions has been performed. Reports on the mailing card prompt immediate mailing of the full questionnaire. For 43 conditions the return rates were in the range of 70-100% and for 7 conditions <70% (unknown 2). The highest return rates were achieved if the principal investigator was supported by staff comprising at least two persons or if the mailing of the questionnaire was handled by the ESPED office. The scientific impact of the ESPED System was assessed by the impact factors of the journals, in which the respective ESPED studies were published. By August 31 (st) 2008 the investigators of 38 studies reported up to 7 publications per conditions surveyed. A total of 104 publications was reported: 27 of these appeared in journals without an impact factor. Among the 77 other publications 10 appeared in journals with an impact factor >10. CONCLUSION Surveillance in ESPED has contributed significantly to high quality research on rare conditions in children.

Abstract
The preparation of chloride (1(n)) and bromide (2(n)) derivatives of 1-methyl-3-[3,4-bis(alkoxy)benzyl]-4H-imidazolium with n = 6, 12, 16, 18 is described. The two series of salts possess a rich thermotropic mesomorphism, chain-length dependent. Thus, a lamellar smectic A phase, a bicontinuous cubic Ia3d phase, and a columnar hexagonal liquid crystalline mesophase are induced as a function of increasing chain length. The mesomorphic properties were studied by polarizing optical microscopy, differential scanning calorimetry, and X-ray diffraction, and with the support of dilatometry and molecular dynamics, models for the various supramolecular arrangements of the salts are proposed. Such cationic amphiphiles were expected to be candidate molecules to design a new delivery reagent for nucleic acid transfection, particularly for short interfering RNA (siRNA). The use of an RNA interference mechanism, by introduction into cells by transfection of chemically synthesized siRNAs, is a powerful method for gene silencing studies. To exploit the potential of these amphilic imidazolium salts, these molecules were formulated with cohelper lipids and tested for their efficacy to deliver active siRNAs. Our results show high transfection efficacy of our formulated compounds and high silencing efficiency with more than 80% inhibition of the targeted gene at 10 nM siRNA concentration. Taken together our results show the potency of amphiphilic imidazolium salts as a new generation of transfection reagents for RNA interference.

Abstract
The merger of ionic liquid and liquid crystal fields, obtained by using the imidazolium ring as a common element, has allowed us to tailor a new set of materials which associate specific functionalities. These functionalities are consequences of the original properties of the component, ionic liquids, liquid crystals and their association in a single compound. The study of this interesting association led us to elaborate environment-flexible cationic architectures from which mesomorphic properties emerge. Moreover, we have also explored the influence of different anions on the mesomorphic properties.

Abstract
Due to the importance of using up-to-date data in information systems, this article analyzes how the data-quality dimension currency can be quantified. Based on several requirements (e.g., normalization and interpretability) and a literature review, we design a procedure to develop probability-based metrics for currency which can be adjusted to the specific characteristics of data attribute values. We evaluate the presented procedure with regard to the requirements and illustrate the applicability as well as its practical benefit. In cooperation with a major German mobile services provider, the procedure was applied in the field of campaign management in order to improve both success rates and profits.
