Abstract
Mutations in the ERBB2 gene were recently found in approximately 2% of primary non-small cell lung cancer (NSCLC) specimens; however, little is known about the functional consequences and the relevance to responsiveness to targeted drugs for most of these mutations. Here, we show that the major lung cancer-derived ERBB2 mutants, including the most frequent mutation, A775insYVMA, lead to oncogenic transformation in a cellular assay. Murine cells transformed with these mutants were relatively resistant to the reversible epidermal growth factor receptor (EGFR) inhibitor erlotinib, resembling the resistant phenotype found in cells carrying the homologous mutations in exon 20 of EGFR. However, the same cells were highly sensitive to the irreversible dual-specificity EGFR/ERBB2 kinase inhibitor HKI-272, as were those overexpressing wild-type ERBB2. Finally, the NSCLC cell line, Calu-3, overexpressing wild-type ERBB2 owing to a high-level amplification of the ERBB2 gene were highly sensitive to HKI-272. These results provide a rationale for treatment of patients with ERBB2-mutant or ERBB2-amplified lung tumors with HKI-272.

Abstract
Autonomous oscillations at the cellular level are important for various timing and signalling functions. The rhythms depend on environmental influences in a specific manner. In particular, the period of some rhythms has been shown to be very robust to certain environmental factors whereas other rhythms show a high sensitivity towards these factors. It is discussed that the robustness of the systems towards environmental changes results from underlying design principles. However, a comparison of robustness properties of different rhythms is lacking. Here we analyse the sensitivity of the oscillatory period with respect to parameter variations in models describing oscillations in calcium signalling, glycolysis and the circadian system. By comparing models for the same and different rhythms it is shown that the sensitivity depends on the oscillatory mechanism rather than the details of the model description. In particular, we find models of calcium oscillations to be very sensitive, those for glycolytic oscillations intermediately sensitive and models for circadian rhythms very robust. The results are discussed with respect to the temperature dependency of the rhythms. The question of what impact design principles have on the robustness of an oscillator, is addressed more explicitly by a direct comparison of systems with positive and negative feedback regulation for various reaction chain lengths. We find that the systems with negative feedback are more robust than corresponding systems with positive feedback. An increase in the length of the reaction chain under regulation leads to a decrease in sensitivity.

Abstract
5090 Background: To determine the dose limiting toxicity and the maximum tolerated dose (MTD) of weekly topotecan in combination with standard dose gefitinib in patients with relapsed, platinum-resistant, ovarian, peritoneal or fallopian tube cancers that are EGF-R positive (>/= 1+). Methods: Patients with measurable, recurrent or persistent cancer after treatment with a platinum and paclitaxel-containing regimen were eligible for this study. Initial treatment was gefitinib at a dose of 250 mg oral dose daily and topotecan at a dose of 2.0 mg/m2 on days 1, 8, and 15, with cycles repeated every 28 days. Dose escalations were planned for topotecan (Dose Levels 1–3: 2, 3, 4 mg/m2) until the MTD was reached. A conventional 3+3 algorithm was used. The 2mg/m2 dose of topotecan was chosen as a starting dose because there are reported responses to this level when it has been used as a single agent on this schedule. Results: Thirteen patients received a total of 45 cycles. Twelve patients were evaluated for toxicity and 11 patients for response. Median age range was 63 years. At the time of initial diagnosis, all twelve patients underwent tumor debulking surgery. One patient had one prior chemotherapy regimen, 6 patients had 2, 4 patients had 3 and 1 patient had more than 3 prior chemotherapy regimens. There were 3 patients treated at dose level 1, 3 patients at dose level 2 and 7 patients treated at dose level 3 (1 patient was inevaluable). One of 6 evaluable patients in the dose level 3 group had a grade 4 thrombocytopenia. Therefore, dose level 3 will used for the Phase II portion of the trial. There were no treatment related deaths. Of the 11 patients evaluated for response, there were 4 patients with stable disease (mean number of cycles 6.5, range 3–12) and 7 had progressive disease. Conclusions: Gefitinib with weekly topotecan infusion is a well-tolerated regimen and suitable for study in platinum-resistant or refractory ovarian or tubal cancers. The phase II component of this study is ongoing. No significant financial relationships to disclose.

Abstract
The paper summarizes the theoretical and practical needs for cellular automata (CA)-type models in coastal simulation, and describes early steps in the development of a CA-based model for estuarine sedimentation. It describes the key approaches and formulae used for tidal, wave and sediment processes in a prototype integrated cellular model for coastal simulation designed to simulate estuary sedimentary responses during the tidal cycle in the short-term and climate driven changes in sea-level in the long-term. Results of simple model testing for both one-dimensional and two-dimensional models, and a preliminary parameterization for the Blackwater Estuary, UK, are shown. These reveal a good degree of success in using a CA-type model for water and sediment transport as a function of water level and wave height, but tidal current vectors are not effectively simulated in the approach used. The research confirms that a CA-type model for the estuarine sediment system is feasible, with a real prospect for coupling to existing catchment and nearshore beach/cliff models to produce integrated coastal simulators of sediment response to climate, sea-level change and human actions.

Abstract
We investigated the impact of five monetary subsidy regimes on economic values of traits in a cow-calf pasture production system with surplus calves fed for slaughter. The following regimes were analysed: (1) maximum prices for slaughter animals actually received in the Czech Republic during 2004, with no subsidies of any kind; (2) prices as in (1), with subsidies awarded per hectare of permanent grassland and per calf born; (3) prices as in (1), with subsidies awarded per hectare of agricultural land, per hectare of pasture and meadow, per beef cow in a forage system and per livestock unit; (4) prices as in (1), with subsidies awarded per hectare of agricultural land; (5) no subsidies, but prices received for slaughter animals that covered production costs and resulted in 1% profitability. The modelled farm showed negative profit under real price conditions with no subsidies (regime 1), which led to an underestimation of economic values for functional traits. The same results were obtained in regimes in which subsidies did not depend on the number of animals (3) or on meat production from the enterprise (4). Economic values of production traits (growth and carcass traits) did not vary among subsidy regimes. To determine optimum economic values for functional traits in beef cattle, we advocate using the method applied in subsidy regime 5, no subsidies but prices for slaughter animals that cover production cost and a small profit.

Abstract
Chediak-Higashi syndrome (CHS) is a rare autosomal recessive lysosomal disorder characterized by frequent infections, oculocutaneous albinism, high bleeding tendency, and various neurological symptoms. Onset in early childhood mostly leads to lymphohistiocytic infiltration into multiple organs, which is usually lethal without bone marrow transplantation. The adult form of CHS has a milder course, no lymphohistiocytic infiltration, and is characterized by neurological manifestations such as polyneuropathy, parkinsonism, dementia, and ataxia. In young adults, a combination of these defects with oculocutaneous albinism or recurrent infections should bring CHS into consideration. Diagnosis is established by the presence of characteristic eosinophilic peroxidase-positive giant granules in leukocytes. This article summarizes current knowledge about the pathogenesis, clinical course, and therapy of CHS and reports on experience with two adult CHS patients.

Abstract
Nucleic acids are well suited to serve as biosensors for the fast and reliable detection of small organic molecules, such as a number of metabolites or antibiotics, specific nucleic acid sequences, peptides, proteins or metal ions. One of the main advantages of using nucleic acids as biosensors is that they can be modulated to respond allosterically to specific effectors. Thus molecular recognition is transformed directly into a catalytic process with observable results. In particular, catalytic RNA structures, such as the hammerhead and hairpin ribozymes, have been used for biosensor engineering. The review reports on the function mode of nucleic acid biosensors and introduces recent developments and applications in the field.

Abstract
OBJECTIVE To determine whether the depiction of injury prevention practices in children's movies released during 1998-2002 is different from an earlier study, which found that characters were infrequently depicted practicing recommended safety behaviors. METHODS The top 25 G (general audience) and PG (parental guidance suggested) rated movies per year from 1998-2002 comprised the study sample. Movies or scenes not set in the present day, animated, documentary, or not in English were excluded; fantasy scenes were also excluded. Injury prevention practices of motor vehicle occupants, pedestrians, bicyclists, and boaters were recorded for characters with speaking roles. RESULTS Compared with the first study, the proportion of scenes with characters wearing safety belts increased (27% v 35%, p<0.01), the proportion of scenes with characters wearing personal flotation devices decreased (17% v 0%, p<0.05), and no improvement was noted in pedestrian behavior or use of bicycle helmets. CONCLUSIONS Despite a modest increase in safety belt usage, appropriate injury prevention practices are still infrequently shown in top grossing G and PG rated movies. The authors recommend that the entertainment industry incorporate safe practices into children's movies. Parents should call attention to the depiction of unsafe behaviors in movies and educate children to follow recommended safety practices.

Abstract
AIMS/HYPOTHESIS The aim of this study was to investigate whether either increased weight or BMI are associated with the earlier manifestation of type 1 diabetes mellitus in children. METHODS We evaluated anthropometric measurements in a large cohort of 9,248 patients of European extraction who were diagnosed in the years 1990-2003 in 116 pediatric clinics throughout Germany and Austria. RESULTS Patients were divided into four groups according to age (0-4.9 years, 5-9.9 years, 10-14.9 years and 15-20 years). Significantly higher standard deviation scores (SDSs) for weight and BMI at diabetes onset were found for both boys and girls in the three younger age groups (up to 14.9 years of age) compared with the reference population (p<0.00001). In addition, the BMI SDS and the weight SDS were significantly higher in the 0-4.9-years age group than in all other groups (p<0.00001), and BMI SDS at onset gradually decreased with increasing age at manifestation (p<0.0001). Over the >10-year study period, there was a continuous rise in the weight-SDS and the BMI-SDS in the cohort (p<0.0001), especially in the 5-9.9-years and the 10-14.9-years age groups. Multivariate analysis revealed a significant influence of male sex and of year of manifestation on BMI SDS (p<0.0001) and demonstrated a negative association between the patients' BMI SDS and age at diagnosis, with a mean annual decrease in BMI SDS of -0.0248 (95% CI -0.0294 to -0.0202, p<0.0001). CONCLUSIONS/INTERPRETATION A higher BMI was associated with a younger age at diabetes onset. Increased weight gain could therefore be a risk factor for the early manifestation of type 1 diabetes.

Abstract
Crossbreeding effects on milk production traits of Czech dual-purpose and dairy cattle breeds were estimated. Nearly 370,000 cows with known gene proportions from Czech Pied, Ayrshire or Holstein cattle were selected from the national milk recording data base. Single-trait animal models were calculated for milk, fat and protein yield, fat and protein content. The model of Dickerson including additive, additive maternal, heterotic and recombination effects was used for the part of the animal model describing the crossbreeding effects in all calculations. For milk yield, the additive genetic effect (defined as deviation from Czech Pied cattle) was 850-900 kg for Holstein and 240-480 kg for Ayrshire. The maternal effects were low and negative. Low significant positive heterotic effects were observed being up to approximately 100 kg for Czech Pied x Holstein. The recombination effects were negative and statistically significant for Czech Pied x Holstein. The results for fat and protein yield were similar to the results for milk yield. For fat and protein content, nearly no statistically significant crossbreeding effects were found.

Abstract
PATIENTS AND METHODS We assessed the frequency of coeliac disease in 281 children with Type 1 diabetes and the effect of gluten-free diet (GFD) in newly diagnosed cases. Serological screening was performed using anti-gliadin and anti-endomysium antibodies. Data were obtained about clinical symptoms, height and weight-for-height. RESULTS A small intestinal biopsy was recommended to 18 patients (6.4%) with positive serological results and 12 children agreed. Nine of them had coeliac disease. Three out of nine coeliac children complained about gastrointestinal symptoms. On a GFD, the symptoms disappeared in two patients. Iron-deficiency anaemia was present in four subjects and disappeared in the three patients who accepted the GFD. In three patients (33%), coeliac disease was asymptomatic. Height and weight-for-height were in the normal range for all patients. For well-complying patients, there was a significant increase in height standard deviation at diagnosis and on follow-up (-0.28 vs. +0.35) (P = 0.03). Changes in weight-for-height were not significant (-4.0% vs. +1.4%) (P = 0.28). There was a trend to an improvement in HbA(1c) (8.0 vs. 7.3%) (P = 0.05). CONCLUSIONS Serological screening is effective. There is a therapeutic benefit for some screening-detected patients, but confirmatory studies are needed.

Abstract
Within the framework of a Tyndall Centre research project, sea level and wave changes around the UK and in the North Sea have been analysed. This paper integrates the results of this project. Many aspects of the contribution of the North Atlantic Oscillation (NAO) to sea level and wave height have been resolved. The NAO is a major forcing parameter for sea-level variability. Strong positive response to increasing NAO was observed in the shallow parts of the North Sea, while slightly negative response was found in the southwest part of the UK. The cause of the strong positive response is mainly the increased westerly winds. The NAO increase during the last decades has affected both the mean sea level and the extreme sea levels in the North Sea. The derived spatial distribution of the NAO-related variability of sea level allows the development of scenarios for future sea level and wave height in the region. Because the response of sea level to the NAO is found to be variable in time across all frequency bands, there is some inherent uncertainty in the use of the empirical relationships to develop scenarios of future sea level. Nevertheless, as it remains uncertain whether the multi-decadal NAO variability is related to climate change, the use of the empirical relationships in developing scenarios is justified. The resulting scenarios demonstrate: (i) that the use of regional estimates of sea level increase the projected range of sea-level change by 50% and (ii) that the contribution of the NAO to winter sea-level variability increases the range of uncertainty by a further 10-20cm. On the assumption that the general circulation models have some skill in simulating the future NAO change, then the NAO contribution to sea-level change around the UK is expected to be very small (<4cm) by 2080. Wave heights are also sensitive to the NAO changes, especially in the western coasts of the UK. Under the same scenarios for future NAO changes, the projected significant wave-height changes in the northeast Atlantic will exceed 0.4m. In addition, wave-direction changes of around 20 degrees per unit NAO index have been documented for one location. Such changes raise the possibility of consequential alteration of coastal erosion.

Abstract
Waves and sea levels have been modelled for the storm of 31 January-1 February 1953. Problems in modelling this event are associated with the difficulty of reconstructing wind fields and validating the model results with the limited data available from 50 years ago. The reconstruction of appropriate wind fields for surge and wave models is examined. The surges and waves are reproduced reasonably well on the basis of tide-gauge observations and the sparse observational information on wave heights. The maximum surge coincided closely in time with tidal high water, producing very high water levels along the coasts of the southern North Sea. The statistics of the 1953 event and the likelihood of recurrence are also discussed. Both surge and wave components were estimated to be approximately 1 in 50 year events. The maximum water level also occurred when the offshore waves were close to their maximum. The estimation of return period for the total water level is more problematic and is dependent on location. A scenario with the 1953 storm occurring in 2075, accounting for the effects of sea level rise and land movements, is also constructed, suggesting that sea level relative to the land could be 0.4-0.5m higher than in 1953 in the southern North Sea, assuming a rise in mean sea level of 0.4m.
